Cumulative fix details for BIG-IP v16.1.3 that are included in this release

999901-1 : Certain LTM policies may not execute correctly after a system reboot or TMM restart.

Links to More Info: K68816502, BT999901

Component: Local Traffic Manager

Symptoms:
After a system reboot or TMM restart, LTM policies referencing an external data-group may not execute correctly, regardless of a successful matching condition.

This can cause a wide range of issues, including misrouted traffic, unshaped traffic, the bypassing of ASM, or complete traffic failure (based on the policy actions).

Note that if a virtual server references multiple LTM policies, and only some of those policies reference an external data-group, all LTM policies attached to the virtual server will be affected.

Conditions:
-- LTM policy with an external data-group configured on a virtual server.
-- System reboot or TMM restart.

Impact:
LTM policies may be unable to execute the appropriate action on a successful matching condition, leading to a wide range of traffic-impacting consequences.

Workaround:
Remove and re-add the affected policy to the desired virtual-server. Alternatively, to fix a wider number of affected virtual servers in one go, reload the system configuration by executing 'tmsh load sys config'.

Fix:
TMM now loads LTM policies with external data-groups as expected.

Fixed Versions:
14.1.4.6, 15.1.5.1, 16.1.2.2


999125-1 : After changing management IP addresses, devices can be stuck indefinitely in improper Active/Active or Standby/Standby states.

Links to More Info: BT999125

Component: TMOS

Symptoms:
After a device (or multiple devices) in a sync-failover device-group undergoes a management IP change, multiple devices in the group can be stuck indefinitely in improper Active/Active or Standby/Standby failover states.

Conditions:
-- One or more devices belonging to a sync-failover device-group undergo a management IP change.

Impact:
-- The affected units are unable to pass traffic, as they are either both Standby or Active (resulting in either no service availability or IP address conflicts in the network).

Workaround:
If you are planning to change management IP addresses on your devices, consider doing so during a maintenance window, in order to account for the eventuality this issue might occur.

Then, if this issue does occur, you can restore correct system functionality by restarting the sod daemon on all units that had their management IP address changed. To do so, run the following command:

tmsh restart sys service sod

Note: This is a one-time workaround, and the issue may re-occur if the devices undergo further management IP address changes in the future.

968581-4 : TMSH option max-response for "show /ltm profile ramcache" command may not comply with its description

Links to More Info: BT968581

Component: Local Traffic Manager

Symptoms:
The TMSH command "show /ltm profile ramcache" has a max-response option to output a number of records designated in this parameter. Due to calculation algorithm, the command may output less records than RAMCACHE stores or more records than the limit prescribes.

Conditions:
-- A virtual server is configured on BIG-IP.
-- A webacceleration profile with no web application is attached to the virtual server.
-- Traffic is sent over the virtual server with a number of unique cacheable documents that exceed a designated limit.

Impact:
Output of the command may not match to actual list of stored documents in RAMCACHE.

Fix:
Command "show /ltm /profile ramcache" respects a limit defined as "max-response" parameter.

962589-4 : Full Sync Requests Caused By Failed Relayed Call to delete_suggestion

Links to More Info: BT962589

Component: Application Security Manager

Symptoms:
When using parent policies with learning enabled in an auto-sync device group, in some use cases deleting an ignored suggestion on a parent policy will cause a full sync to occur.
This can cause unexpected delays in configuration being synchronized between peers, and in the event of repeated instances in quick succession could fill the /var partition

Conditions:
1) Device Group with ASM and auto-sync enabled
2) Parent Policies with learning are in use.
3) Ignored Suggestions are deleted on the parent policy after they have 0 suggesting children left.

Impact:
ASM configuration requests a full sync which can cause unexpected slowness in config synchronization and may fill the /var partition if done multiple times in quick succession.
A full /var partition can lead to bd cores.

Fixed Versions:
14.1.4.4, 15.1.4, 16.1.1

953601-4 : HTTPS monitors marking pool member offline when restrictive ciphers are configured for all TLS protocol versions

Links to More Info: BT953601

Component: Local Traffic Manager

Symptoms:
HTTPS monitor marks pool member/nodes as down and they remain down until bigd is restarted or the monitor instance is removed and created again.

Conditions:
BIG-IP is configured with restrictive ciphers that are only compatible with TLS 1.2 (ECDH+AESGCM) but all of the TLS protocol versions are allowed. When HTTPS monitor TLS 1.0 handshake fails, due to incompatible ciphers with the server being monitored. It does not try TLS 1.2 version and marks pool members or nodes as down.

948113-1 : User-defined report scheduling fails

Links to More Info: BT948113

Component: Application Visibility and Reporting

Symptoms:
A scheduled report fails to be sent.

An error message with the following format may appear on /var/log/avr/monpd.log file (some parts of the error message were replaced with '.....' in here to leave only the common parts):
     DB|ERROR|....... Error (err-code 1054) executing SQL string :
.....
.....
.....
 Because : Unknown column ....... in 'order clause'

Conditions:
1. Using predefined-report in scheduled-report.
2. Predefined-report has more than one measure.
3. Sort-by value is different from the first measure on predefined-report

Impact:
Internal error for AVR report for ASM pre-defined.

Workaround:
First, remount /usr to read-write:
mount -o remount,rw /usr

Next, open file /usr/share/perl5/vendor_perl/F5/AVReporter/Client.pm and change the following line:
push(@measures,@{$base_request->{measures}}[0]);
to this:
push(@measures,@{$base_request->{sort_by}}[0]->{measure});

The above can be achieved with the following script-line (please first backup the Client.pm file and then verify it changed it correctly):
sed -i 's/push(@measures,@{\$base_request->{measures}}\[0\])/push(@measures,@{$base_request->{sort_by}}[0]->{measure})/' /usr/share/perl5/vendor_perl/F5/AVReporter/Client.pm

Lastly, remount /usr back to read-only:
mount -o remount,ro /usr

Fix:
Using 'sort-by' measure when building PDF (instead of the first value on measure-list)

947341-4 : MySQL generates multiple error 24 (too many files open) for PRX.REQUEST_LOG DB tables files.

Links to More Info: BT947341

Component: Application Security Manager

Symptoms:
1) var/lib/mysql/mysqld.err is filled with log entries that contain:
------------
  200824 11:04:43 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24)
  200824 11:18:46 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24)
  200824 11:35:58 [ERROR] mysqld: Can't open file: './PRX/REQUEST_LOG.frm' (errno: 24)
------------

2) There are a lot of PRX.REQUEST_LOG partitions, in some cases up to 1024, many of which are empty.

Conditions:
ASM/AVR provisioned

Impact:
MySQL runs out of resources when opening the file
PRX.REQUEST_LOG and an error message states the file is corrupt.

Workaround:
1. If the /appdata partition is filled to 100% and MySQL restarts continuously, refer to the following Knowledge Articles:
   https://support.f5.com/csp/article/K14956
   https://support.f5.com/csp/article/K42497314

2. To identify the empty partitions, look into:
   mysql -su root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e "SELECT * FROM INFORMATION_SCHEMA.PARTITIONS WHERE table_name = 'REQUEST_LOG' AND table_schema = 'PRX'\G"

3. For every partition that is empty, manually (or via shell script) execute this sql:
   mysql -su root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e "ALTER TABLE PRX.REQUEST_LOG DROP PARTITION <empty_partition_name>;"

   Note: <empty_partition_name> must be substituted with the partition name, for example p100001.


4. Increase 'open_files_limit' to '10000'.
--------------------------------

   In the /etc/my.cnf file:
   1. Change the value of the 'open_files_limit' parameter to 10000.
   2. Restart MySQL:
   bigstart restart mysql
--------------------------------

5. pkill asmlogd

Note: This workaround does not survive upgrade. It must be reapplied after every upgrade until the upgraded version contains a fix.

Fix:
This release increases the default 'open_files_limit' to '10000'.

Fixed Versions:
14.1.4.1, 15.1.3, 16.0.1.2, 16.1.2

945357 : BIG-IP must be able to set CA=True when creating Certificate Signing Requests from TMSH.

Links to More Info: BT945357

Component: Local Traffic Manager

Symptoms:
A Certificate Signing Request (CSR) is generated on the BIG-IP device to be used to create a certificate. It is possible for the entity owning the just-created certificate to serve as a Certificate Authority (CA) and be able to issue certificates and private keys to other parties. However, that ability does not exist unless the certificate has the CA field set to True (by default it is set to False).

Conditions:
In the TMSH prompt on the Command Line Interface (CLI), an attempt is made to generate a Certificate Signing Request (CSR) to be used to eventually create a certificate and corresponding private key.

Impact:
Without this change, certificates and private keys generated on the BIG-IP device cannot be directly provided to certification authorities so they can be used to sign certificates they would issue to other parties.

Workaround:
This is a new facility, not provided before, and overcomes a limitation. Without this facility, existing users of the BIG-IP are not impacted at all. As such, there is no workaround applicable.

Fix:
This fix enables certificates and private keys generated on the BIG-IP device via CSR's to be directly provided to certification authorities for their use. Because the CA field is set to now True, this fix adds convenience for certification authorities.

Fixed Versions:
16.1.3

943577-1 : Full sync failure for traffic-matching-criteria with port list under certain conditions

Links to More Info: BT943577

Component: TMOS

Symptoms:
Performing a full configuration sync with traffic-matching-criteria (TMC) under specific conditions fails with errors similar to:

err mcpd[6489]: 01070710:3: Database error (13), Cannot update_indexes/checkpoint DB object, class:traffic_matching_criteria_port_update status:13 - EdbCfgObj.cpp, line 127.
err mcpd[6489]: 01071488:3: Remote transaction for device group /Common/Failover to commit id 245 6869100131892804717 /Common/tmc-sync-2-bigip1.test 0 failed with error 01070710:3: Database error (13), Cannot update_indexes/checkpoint DB object, class:traffic_matching_criteria_port_update status:13 - EdbCfgObj.cpp, line 127..

Conditions:
This may occur on a full-load config sync (not an incremental sync)
On the device receiving the ConfigSync:
   - a traffic-matching-criteria is attached to a virtual server
   - the traffic-matching-criteria is using a port-list
On the device sourcing the ConfigSync:
   - the same traffic-matching-criteria is attached to the same virtual server
   - the original port-list is modified (e.g. a description is changed)
   - the TMC is changed to reference a _different_ port-list

Impact:
Unable to sync configurations.

Workaround:
Copy the "net port-list" and "ltm traffic-matching-criteria" objects from the source to target system, merge them with "tmsh load sys config merge", and then perform a force-full-load-push sync from source to target.

If the BIG-IP systems are using device groups with auto-sync enabled, disable auto-sync temporarily while performing this workaround.

1. On the source system (the system whose configuration you want to sync to peer), save the configuration and extract the ltm traffic-matching-criteria and port-lists:

tmsh save sys config

(shopt -s nullglob; echo "#"; echo "# $HOSTNAME"; echo "# generated $(date +"%F %T %z")"
    cat /config{/partitions/*,}/bigip{_base,}.conf |
    awk '
        BEGIN { p=0 }
        /^(ltm traffic-matching-criteria|net port-list) / { p=1 }
        /^}/ { if (p) { p=0; print } }
        { if (p) print; }
    ' ) > /var/tmp/portlists-and-tmcs.txt

2. Copy /var/tmp/portlists-and-tmcs.txt to the target system

3. On the target system, load that file:

    tmsh load sys config replace file /var/tmp/portlists-and-tmcs.txt

3a. If loading the config file on the target system fails with the same error message seen during a ConfigSync, follow the procedure in
K13030: Forcing the mcpd process to reload the BIG-IP configuration :: https://support.f5.com/csp/article/K13030.

   tmsh save sys config
   clsh touch /service/mcpd/forceload
   clsh reboot

4. On the source system, force a full-load sync to the device-group:

    tmsh run cm config-sync force-full-load-push to-group <name of sync-group>

939877-3 : OAuth refresh token not found

Links to More Info: BT939877

Component: Access Policy Manager

Symptoms:
When an OAuth client sends a refresh token to renew the access token, BIG-IP reports an error:

err tmm[13354]: 01990004:3: /Common/my_OAuth_v1:Common: Request Refresh Token from Source ID ... failed. Error Code (id_not_found) Error Description (The refresh token is not found)

Conditions:
-- The refresh token expiration interval is longer than authcode and accesstoken.
-- The Authorization code table entry does not exist because of an internal clearing/purging operation.
-- tmm restarts or failover to standby thus losing refresh-token value from primarydb

Impact:
OAuth APM client end user fails to renew the access token even with a valid refresh token.

Workaround:
Clear/reset the Authorization code column value manually:

As a root user run below BIG-IP shell
(tmos)# list apm oauth db-instance
apm oauth db-instance oauthdb { db-name <db_name> description "Default OAuth DB." }

Copy the value corresponding to <db_name>.

Log into mysql from the bash prompt:
# mysql -u root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw)

mysql> use <db_name>;

mysql> update master set auth_code = NULL where refresh_token='affected_refresh_token_id';

(Substitute the affected refresh token ID with affected_refresh_token_id in the previous command.)

Fix:
Do not report error if the Authorization code does not exist when a valid refresh-token/access-token exists.

14.1.4.4, 15.1.4, 16.1.2


936441-7 : Nitrox5 SDK driver logging messages

Links to More Info: BT936441

Component: Local Traffic Manager

Symptoms:
The system kernel started spontaneously logging messages at an extremely high rate (~3000 per second):

Warning kernel: EMU(3)_INT: 0x0000000000000020
warning kernel: sum_sbe: 0
warning kernel: sum_dbe: 0
warning kernel: sum_wd: 0
warning kernel: sum_gi: 0
warning kernel: sum_ge: 0
warning kernel: sum_uc: 1

The above set of messages seems to be logged at about 2900-3000 times a second.

These messages continue after TMM fails its heartbeat and is killed. The system is rebooted by the host watchdog.

Conditions:
These messages are triggered by Nitrox5 driver when EMU microcode cache errors corrected by hardware.

Impact:
High rate of logging messages. The tmm heartbeat eventually fails, and tmm is restarted. Traffic disrupted while tmm restarts.

Workaround:
None.

Fixed Versions:

935249-3 : GTM virtual servers have the wrong status

Links to More Info: BT935249

Component: Global Traffic Manager (DNS)

Symptoms:
GTM virtual servers have the wrong status (up when they should be down, or down when they should be up).

Conditions:
-- The GTM virtual servers are monitored with an HTTP or HTTPS monitor that performs HTTP status matching.

-- The status code (for example, 200) being searched for in the response appears elsewhere than in the first line (for example, in a following header).

Impact:
The system incorrectly matches the status code in a response line which is not the Status-Line. As a result, the availability status reported for a virtual server may be incorrect. This may cause the GTM system to send traffic to unsuitable resources causing application disruptions.

Workaround:
You can work around this issue by not performing HTTP status matching in your HTTP/HTTPS GTM monitors.

Fix:
The HTTP status code is now correctly searched only in the first line of the response.

Fixed Versions:
15.1.5, 16.1.2.1


935177-3 : IPsec: Changing MTU or PMTU settings on interface mode tunnel cores tmm

Links to More Info: BT935177

Component: TMOS

Symptoms:
TMM crashes when the maximum transmission unit (MTU) or 'Use PMTU' setting is changed while passing IPsec traffic.

Conditions:
-- IPsec tunnel configured and passing traffic.
-- The MTU or 'Use PMTU' setting for the IPsec tunnel (in interface mode) is changed.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not change MTU or PMTU settings for the tunnel while it is passing traffic.

The settings can be changed while passing traffic, but TMM may crash very soon after the change. If the settings are changed and TMM does not crash soon after, then it will not spontaneously crash at some later point.

Fixed Versions:
16.1.2.2


934697-5 : Route domain not reachable (strict mode)

Links to More Info: BT934697

Component: Local Traffic Manager

Symptoms:
Network flows are reset and errors are found in /var/log/ltm:

Route domain not reachable (strict mode).

Conditions:
This might happen in either of the following scenarios:
Scenario 1
==========
-- LTM with iRules configured.
-- The iRule directs traffic to a node that is in a route domain.

Scenario 2
==========
-- LTM with an LTM policy configured.
-- The policy directs traffic to a node that is in a route domain.

Impact:
Traffic is not sent to the node that is in a route domain.

The iRule 'node' method and/or LTM policy 'node' specification require a route_domain to be specified in order for the traffic to be sent to a node that is assigned to a route domain.

Workaround:
Specify the node along with Route domain ID.

-- For iRules, change from this:
when HTTP_REQUEST {
 node 10.10.10.10 80
}

To this (assuming route domain 1):
when HTTP_REQUEST {
 node 10.10.10.10%1 80
}


-- For LTM policies, change from this:
actions {
    0 {
        forward
        select
        node 10.2.35.20
    }
}

To this (assuming route domain 1):
actions {
    0 {
        forward
        select
        node 10.2.35.20%1

932133-1 : Payloads with large number of elements in XML take a lot of time to process

Links to More Info: BT932133

Component: Application Security Manager

Symptoms:
ASM experiences high CPU and latency usage while processing a large XML request.

Conditions:
-- ASM provisioned
-- HTTP request with a large XML payload (several MB) is sent to the backend server which triggers the XML parser.

Impact:
High CPU and latency occurs while bd processes the payload. This may cause a bottleneck for different requests that arrive concurrently with the large XML payload request.

Workaround:
None

Fix:
This fix includes performance improvements for large XML payloads.

Fixed Versions:
13.1.5, 14.1.4.4, 15.1.4.1, 16.1.2

929213-2 : iAppLX packages not rolled forward after BIG-IP upgrade&start;

Links to More Info: BT929213

Component: Device Management

Symptoms:
Certain iAppLX packages are not rolled forward after a BIG-IP upgrade or restoring a UCS file generated from an affected system, and will be unavailable for use.

1. f5-cloud-failover-1.4.0-0.noarch.rpm
2. f5-service-discovery-1.2.9-2.noarch.rpm
3. f5-telemetry-1.12.0-3.noarch.rpm

Conditions:
-> Installing any of the below iAppLX packages
1. f5-cloud-failover-1.4.0-0.noarch.rpm
2. f5-service-discovery-1.2.9-2.noarch.rpm
3. f5-telemetry-1.12.0-3.noarch.rpm

-> Performing an upgrade

-> Trying to access the LX packages from GUI by navigating to iApps -> Package Management LX

Impact:
After upgrading or restoring a UCS file generated from an affected system, the cloud-failover, service discovery, and telemetry iAppLX apps are not available for use, and will result in 404 error, while accessing them from GUI

Workaround:
The package needs to be uninstalled and installed again for use.

Steps:
-> From GUI, Navigate to iApps -> Package Management LX
-> select the package to uninstall and click on Uninstall
-> click on Import and provide the path of package to install again

Fix:
A new database key has been added, 'sys db iapplxrpm.timeout', which allows the RPM build timeout value to be increased.

sys db iapplxrpm.timeout {
    default-value "60"
    scf-config "true"
    value "60"
    value-range "integer min:30 max:600"
}

For example:

tmsh modify sys db iapplxrpm.timeout value 300

tmsh restart sys service restjavad

Increasing the db key and restarting restjavad should not be traffic impacting.

After increasing the timeout, the RPM build process that runs during a UCS save should be successful, and the resulting UCS should include the iAppsLX packages as expected.

Note: The maximum db key value of 600 may be needed in some cases.

Conditions:
-- Configuration contains active and inactive ASM policies.
-- Upgrade the BIG-IP system to any later version.
-- You can check existing ASM policies in tmsh:
tmsh list asm policy

Impact:
Only the active ASM policies are preserved; the inactive policies are deleted.

Workaround:
None.

924945-5 : Fail to detach HTTP profile from virtual server

Links to More Info: BT924945

Component: Application Visibility and Reporting

Symptoms:
The virtual server might stay attached to the initial HTTP profile.

Conditions:
Attaching new HTTP profiles or just detaching an existing one.

Impact:
The virtual server stays attached to the former HTTP profile, meaning that the virtual server might be attached to a different HTTP profile than what the GUI displays. Configuration changes to the HTTP profile the GUI shows as attached are not reflected in the virtual server. For example, the new HTTP profile might enable XFF, but if the former attached profile does not enable it, the virtual server does not accept XFF.

Workaround:
Create new similar virtual server and attach it to the correct HTTP profile.

Fixed Versions:
15.1.3, 16.0.1.2, 16.1.1


923221-8 : BD does not use all the CPU cores

Links to More Info: BT921697

Component: Application Security Manager

Symptoms:
Installing a new Attack Signature Update (ASU) file on ASM/AWAF device that has large number of active policies can result in a failure due to memory exceptions. The following errors can be observed:

/var/log/ts/asm_config_server.log:
F5::ASMConfig::Handler::handle_error,,Code: 406 , Error message = Process size (232341504) has exceeded max size (200000000)

Conditions:
1. Adding and activating a large number of policies on a BIG-IP system configured with ASM/AWAF. It is not known exactly how many policies are required to encounter this, but it appears to be between 50 and 90 where this becomes a risk.

2. Installing a new ASU file

Impact:
The attack signature update fails.

Workaround:
Impact of workaround:
Performing this workaround requires restarting ASM, so it affects traffic processing briefly; therefore, it is recommended that you perform this during a maintenance window.

Increase 'max memory size' from the default ~200 MB (200000000) to 300 MB:

1. Take a backup of the original file.
# cp /etc/ts/tools/asm_config_server.cfg /var/tmp/asm_config_server.original.cfg

2. Add the following to the end of file /etc/ts/tools/asm_config_server.cfg:
# AsyncMaxMemorySize=314572800

3. Restart ASM.
# bigstart restart asm

921365-2 : IKE-SA on standby deleted due to re-transmit failure when failing over from active to standby

Links to More Info: BT921365

Component: TMOS

Symptoms:
IKE-SAs are deleted on standby BIG-IP systems after a failover.

Conditions:
-- High availability (HA) environment
-- Dead-peer detection (DPD) / liveness checks are enabled
-- An HA failover occurs

This is a timing issue and can occur intermittently during a normal failover.

Impact:
Some of the IKE-SAs are missing on the standby device. When a failover happens, IPsec traffic will be dropped for those missing SAs.

Workaround:
Set IKE DPD interval time to ZERO (i.e., disable).

Fix:
When the BIG-IP system is in standby mode, the system no longer retries sending IKE/IPSEC control messages, which prevents this issue from occurring.

Fixed Versions:
15.1.4, 16.1.2

912149-7 : ASM sync failure with Cgc::Channel error 'Failed to send a message, error:15638476'

Links to More Info: BT912149

Component: Application Security Manager

Symptoms:
The system exhibits various symptoms related to sync and control plane, and reports errors similar to the following:

/var/log/:

asm:
-- (asm_config_server.pl,F5::Cgc::Channel::send): Failed to send a message, error:15638476.

ts_debug.log:
-- |ZEROMQ|May 21 23:27:31.840|24813|25914|25914|epoll.cpp:0060|~epoll_t()|(zmq_assert) Assertion failed: load.get () == 0

Conditions:
-- Two devices in a sync-failover/sync-only device group.
-- Other conditions required to reproduce this issue are under investigation.

Note: The occurrences of the Cgc::Channel message in the /var/log/ and /var/log/ts/asm_config_server logs are the most reliable indicator of this issue.

Impact:
-- Config-sync does not work, resulting in a different configuration among the devices in a sync group.

-- Security log profile changes are not propagated to other devices.

-- Portions of the GUI hang, e.g.: Security module tab, and 'security' menu under virtual server.

-- Policies with learning enabled do not generate learning suggestions.

Workaround:
Restart asm_config_server on the units in the device group.

# pkill -f asm_config_server

911141-1 : GTP v1 APN is not decoded/encoded properly

Links to More Info: BT911141

Component: Service Provider

Symptoms:
GTP v1 APN element was decoded/encoded as octetstring and Only GTP v2 APN element is decoded/encoded as DNS encoding.

Conditions:
- GTP version 1.
- APN element.

Impact:
iRules become more complex when dealing with GTP v1 APN element, as it may need to convert between octetstring and dotted style domain name value after decoding or before encoding the data.

Workaround:
Use iRules to convert between octetstring and dotted style domain name values.

Fix:
GTP version 1 APN information element is now decoded/encoded as DNS encoding.

Behavior Change:
GTP v1 apn element is now decoded/encoded using DNS-like encoding. Previously, it was decoded/encoded as octetstring.

Fixed Versions:
13.1.5, 14.1.4.4, 15.1.4, 16.1.1

910213-7 : LB::down iRule command is ineffective, and can lead to inconsistent pool member status

Links to More Info: BT910213

Component: Local Traffic Manager

Symptoms:
Use of the LB::down command in an iRule may not have the desired effect, or may result in pool members that are down for load balancing, but indicate up/available in the GUI and CLI.

Specifically, the pool member is marked down within the tmm instance executing the iRule, but the status change is not updated to mcpd, or to other tmm instances.

As a result, the message 'Pool /Common/mypool member /Common/1.1.1.1:80 monitor status iRule down' does not appear in the log, and the status of the pool member is not updated when viewed in the GUI or via 'tmsh show ltm pool xxxx members'.

Note: If [event info] is logged in the LB_FAILED event, it will indicate that the load balancing decision failed due to "connection limit"

Conditions:
Using the LB::down command in an iRule.

Impact:
Because mcpd believes the pool member to be up, it does not update tmm's status, so tmm continues to regard it as down indefinitely, or until a monitor state change occurs.

If the LB::down command is used on all members of a pool, the affected tmms cannot load balance to that pool, even though the GUI/tmsh indicate that the pool has available members.

Because pool member status is stored on per-tmm basis and incoming connections are distributed across tmms using a hash, this can lead to apparently inconsistent results, where some traffic (traffic hitting a particular tmm) is rejected with an RST cause of 'No pool member available'.

Workaround:
- Delete and recreate affected pool members
(or) Restart tmm
(or) Restart the BIG-IP.

There is no direct workaround, but the use of an inband monitor instead of the LB::down command may be effective. You must tune the inband monitor's settings to values consistent with the desired behavior.

901669-6 : Error status in 'tmsh show cm failover-status', and stale data in some tmstat tables, after management IP address change.

Links to More Info: BT901669

Component: TMOS

Symptoms:
-- The 'tmsh show cm failover-status' command shows a status of 'Error' when the command is run on a peer of a device that underwent a management IP address change.

-- Should the sod_tg_conn_stat or sod_tg_msg_stat tmstat tables be inspected using the tmctl command, the tables show stale information in the entry_key column.

Note: Additionally, in certain cases, it is possible for failover functionality to be broken after the management IP address change, meaning devices remain stuck in an improper Active/Active or Standby/Standby state. This further aspect of the issue is tracked under ID999125. This ID tracks only the cosmetic defect.

Conditions:
-- Two or more devices in a sync-failover device-group.
-- The management IP address is changed on one of the devices.

The error appears under either of these conditions:
-- The 'tmsh show cm failover-status' is run on a peer of the device that underwent the management IP address change.
-- The sod_tg_conn_stat or sod_tg_msg_stat tmstat tables are inspected using the tmctl command.

Impact:
The 'tmsh show cm failover-status' command indicates an error.

Workaround:
You can work around this issue by running the following command on the peers of the device which underwent a management IP address change:

tmsh restart sys service sod

895557-5 : NTLM profile logs error when used with profiles that do redirect

Links to More Info: BT895557

Component: Local Traffic Manager

Symptoms:
As of BIG-IP version 14.1, HTTP iRule commands that inspect HTTP state after the commands HTTP::respond, HTTP::redirect, and HTTP::retry returns errors instead of returning corrupt data (https://support.f5.com/csp/article/K23237429).

When the NTLM profile is configured, it does the same through a built-in TCL rule where among several things, it tries to check if HTTP::cookie exists. If a profile like HTTP exists wherein a redirect/respond/retry is configured, it results in a TCL error informing the admin that they are accessing an invalid HTTP state.

Conditions:
-- NTLM profile is configured alongside HTTP profile
-- One of the redirect/respond/retry commands has been executed before the NTLM profile accesses the state of HTTP (for ex. HTTP::collect, HTTP::close, HTTP::cookie, etc.).

Impact:
Tcl error is seen in /var/log/ltm informing the admin that the iRule operation executed after HTTP::redirect/retry/respond is not supported.

For example -
TCL error: _plugin_rule_/Common/ntlm_default_iis <HTTP_REQUEST> - ERR_NOT_SUPPORTED (line 1) invoked from within "HTTP::cookie exists [PROFILE::ntlm insert_cookie_name]"

Conditions:
-- The payload is filled with the percent character in between every other character.
-- The bad unescape violation is turned off.
-- The illegal metacharacter violation is turned off.

Impact:
An attack goes undetected.

Workaround:
Turn on the bad unescape violation or the metacharacter violation.

Fix:
Added an internal parameter, normalization_remove_percents. Its default is 0 (zero), meaning that the previous behavior is maintained. When enabled, the normalization of the data before running the signature removes the percent characters (as it does to high ASCII and space characters).

882709-6 : Traffic does not pass on tagged VLANs on VE configured on Hyper-V hypervisors&start;

Links to More Info: BT882709

Component: TMOS

Symptoms:
Traffic does not pass on tagged VLANs when a BIG-IP Virtual Edition (VE) is deployed on a Hyper-V hypervisor.

This may manifest as traffic failing after an upgrade from earlier (unaffected) software versions.

Note: This functionality worked as expected in v13.x and earlier, and if the same VE is downgraded to v13.x, VLAN tagging functionality is restored.

This is due to an interoperability issue between RedHat Enterprise Linux (RHEL) and Microsoft Hyper-V, which seems to affect RHEL v7.3 and RHEL v7.5.

Hyper-V on Windows Server 2016 and Windows Server 2012 do not seem to identify the version of the built-in LIS correctly on Centos 7.3 or Centos 7.5 (which are built on RHEL 7.3 and RHEL 7.5 respectively).

Although there is a statement of support by Microsoft for VLAN tagging on RHEL 7.3 and 7.5 when running on Hyper-V, that functionality does not appear to work at present: Supported CentOS and Red Hat Enterprise Linux virtual machines on Hyper-V :: https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/Supported-CentOS-and-Red-Hat-Enterprise-Linux-virtual-machines-on-Hyper-V.

Conditions:
-- BIG-IP VE is deployed on a Hyper-V hypervisor.
-- VLAN configured in BIG-IP VE with tagged interfaces, e.g.:

    net vlan external {
        interfaces {
            1.1 {
                tagged
            }
        }
        tag 4000
    }

-- At present, VLAN tagging on the v14.x and v15.x releases does not work because those releases are running on CentOS 7.3 and 7.5 respectively, which both are affected by the MS/RHEL interoperability issue.

-- BIG-IP v12.x and v13.x use a different (older) CentOS version, so VLAN tagging works without issue on those releases.

Impact:
-- The system does not prevent you from configuring tagged VLANs, even though they do not pass traffic.

-- Although upgrades complete and you can reboot into the new boot location (or you can set up on Hyper-V from scratch), traffic does not pass (into the guest) across VLANs that are tagged.

Important: If using tagged VLANs on VE setups on Hyper-V is critical to your configuration, you might want to elect to postpone upgrading from a working, v12.x and v13.x release.

Workaround:
Essentially, there is no workaround in this release; you must reconfigure the virtual machine to use separate, untagged interfaces for each VLAN.

Note: Although this is technically a problem between Hyper-V and the built-in LIS on RHEL 7.3/7.5, this issue is being tracked internally in this bug.

Behavior Change:
In this release, traffic does not pass on tagged VLANs when a BIG-IP Virtual Edition (VE) is deployed on a Hyper-V hypervisor.

This functionality worked as expected in v13.x and earlier, and if the same VE is downgraded to v13.x, VLAN tagging functionality is restored.

Important: If using tagged VLANs on VE setups on Hyper-V is critical to your configuration, you might want to elect to postpone upgrading from a working, v12.x and v13.x release.

881085-4 : Intermittent auth failures with remote LDAP auth for BIG-IP managment

Links to More Info: BT881085

Component: TMOS

Symptoms:
There are intermittent auth failures when accessing the BIG-IP administration interfaces via SSH or the GUI.

Conditions:
-- Remote LDAP auth is configured.
-- An idle timeout RST is received on the LDAP connection before the configured auth LDAP idle-timeout expires. This RST might be generated by tmm (if the connection to the LDAP server is via a defined VLAN), some other intervening device on the network, or from the LDAP server itself (depending on its connection time limit).

Impact:
There might be intermittent remote-auth failures.

Workaround:
Set the auth ldap idle-timeout to a smaller value, for example, via tmsh:
modify auth ldap system-auth idle-timeout 299

Fixed Versions:
14.1.4.5, 15.1.4.1, 16.1.2


876677-2 : When running the debug version of TMM, an assertion may be triggered due to an expired DNS lookup.

Links to More Info: BT876677

Component: Global Traffic Manager (DNS)

Symptoms:
When running the debug version of TMM, if a particular DNS lookup takes more than 30 seconds, TMM may assert with a message in the /var/log/tmm file similar to the following example:

notice panic: ../modules/hudfilter/3dns/cache_resolver.c:2343: Assertion "standalone refcnt must be one" failed.

Conditions:
-- Using the debug TMM
-- Using the RESOLV::lookup iRule command
-- The DNS server targeted by the aforementioned command is running slowly or malfunctioning

Impact:
TMM crashes and, in redundant configurations, the unit fails over.

Workaround:
Do not use the debug TMM.

Fix:
The debug assert was removed and replaced by a debug log.

Fixed Versions:
16.1.2.2


874941-4 : HTTP authentication in the access policy times out after 60 seconds

Links to More Info: BT874941

Component: Access Policy Manager

Symptoms:
HTTP authentication in the access policy times out after 60 seconds, where previously, the timeout was 90 seconds.

Conditions:
Encountering the timeout of HTTP authentication in the access policy in this version of the software.

Impact:
HTTP authentication times out 30 seconds earlier than it did in previous versions. There is no way to configure this timeout value, so authentication fails for operations that require greater than 60 seconds to complete.

Workaround:
None.

Fix:
Added options to configure the HTTP connection and request timeouts in HTTP authentication.

1. A db key to configure Connection Timeout for HTTP Server configuration:

+[APM.HTTP.ConnectionTimeout]
+default=10
+type=integer
+min=0
+max=300
+realm=common
+scf_config=true
+display_name=APM.HTTP.ConnectionTimeout


2. A db key to configure Request Timeout for HTTP Server configuration:

+[APM.HTTP.RequestTimeout]
+default=60
+type=integer
+min=0
+max=600
+realm=common
+scf_config=true
+display_name=APM.HTTP.RequestTimeout

Behavior Change:
Added db variables APM.HTTP.ConnectionTimeout and APM.HTTP.RequestTimeout as options to configure the HTTP connection and request timeouts in HTTP authentication.

The APM.HTTP.ConnectionTimeout defaults to 10 seconds, and the APM.HTTP.RequestTimeout defaults to 60 seconds.

Note: These defaults are the same as the values in earlier releases, so there is no effective functional change in behavior.

854129-6 : SSL monitor continues to send previously configured server SSL configuration after removal

Links to More Info: BT854129

Component: In-tmm monitors

Symptoms:
After an SSL profile has been removed from a monitor, a monitor instance continues to use settings from the previously-configured server SSL profile, such as client certificate or ciphers or supported TLS versions.

Conditions:
-- In-TMM monitors enabled.
-- SSL monitor configured with a server SSL profile.
-- Setting the monitor's 'SSL Profile' parameter to 'none'.

Impact:
The previously configured settings, such as certificate or cipher, continue to be used for monitoring pool members, which may result in unexpected health check behavior/pool member status.

Workaround:
An administrator can avoid this issue by ensuring the monitor's 'SSL Profile' parameter specifies a profile (i.e., is not 'none').

Note: In some software versions, changing a monitor's SSL profile from one profile to a different profile may not take effect. For information about this behavior, see https://cdn.f5.com/product/bugtracker/ID912425.html

844045-4 : ASM Response event logging for "Illegal response" violations.

Links to More Info: BT844045

Component: Application Security Manager

Symptoms:
Response log is not available when the request is legal but returns an illegal response status code.
In ASM, logging profiles allow the logging of all blocked responses. The existing response logging allows either all requests or illegal requests only which does not contain response logging data.

Conditions:
-- Response logging is enabled
-- An illegal response occurs

Impact:
Response logging does not occur.

Workaround:
N/A

Fix:
When a response has ASM response violations and response logging is enabled only for when there was a violation, ASM includes the response in the log.

Added an internal variable:

842013-1 : ASM Configuration is Lost on License Reactivation&start;

Links to More Info: BT842013

Component: Application Security Manager

Symptoms:
After re-activating a BIG-IP license, if the configuration fails to load and reverts to a base config load, the ASM policy config contains 'default' or 'stub' policies, even after fixing the error that caused the configuration to fail to load.

Conditions:
1) A parsing error exists in the BIG-IP config such that 'tmsh load sys config verify' would fail
2) There is a license reactivation or the configuration is reloaded

Impact:
ASM policy configuration is lost and all policies are reverted to empty 'stubs'

Workaround:
In the case of license re-activation/before upgrade:

   Run the command "tmsh load sys config verify" prior to license activation on ASM units to be sure that the config will pass parsing and avoid the fallback to base configuration load.

   In a case of booting the system into the new version:

   Option 1:

      1. Using the steps in either K4423 or K8465, fix the issue that was preventing the config to load.
      2. Reload the config from the fixed UCS file using the command in K13132.

   Option 2:

      1. Roll back to the old version.
      2. Fix the issue that was preventing the config to load.
      3. Before activating the Boot Location of the new version at System >> Software Management : Boot Locations, make sure to set the option Install Configuration to Yes. see: K64400324

   Option 3: If one of the high availability (HA) units successfully upgraded, then use config-sync to push the working config to the failing unit.

838305-9 : BIG-IP may create multiple connections for packets that should belong to a single flow.

Links to More Info: BT838305

Component: Local Traffic Manager

Symptoms:
Due to a known issue, BIG-IP may create multiple connections for packets that should belong to a single flow. These connections will stay in the connection table until the idle timeout is reached. These connections can be used for forwarding the traffic.

Conditions:
BIG-IP may create multiple connections for packets that should belong to a single flow when both following conditions are true:
- Packets are coming at a very high rate from the network.
- Flow handling these packets is torn down.

Impact:
This might result in packets from the client being handled by one flow and packets from the server being handled by a different flow.

830341-5 : False positives Mismatched message key on ASM TS cookie

Links to More Info: BT830341

Component: Application Security Manager

Symptoms:
ASM system triggers false positives for ASM Cookie Hijacking violation with reason "Mismatched message key"

Conditions:
-- An HTTP request containing an old frame cookie with a different message key from the main ts cookie is rejected
-- The cookie is left intact

Impact:
All subsequent requests are rejected on ASM Cookie Hijacking violation

Workaround:
1. Disable "Learn Host Names" flag all policies. If the policy builder is on manual mode, they need to change it back to Auto mode, disable "Learn Host Names", then change to manual mode.

OR

2. Delete the mismatched cookie. This will cause the violations to stop occurring if the request comes from a legit endpoint

Fix:
In order to activate the changed functionality, set internal parameter ignore_cookies_msg_key to 1 and restart asm by executing following commands in CLI:
/usr/share/ts/bin/add_del_internal add ignore_cookies_msg_key 1
bigstart restart asm

Once enabled, ASM system does not trigger false positives.

828761-5 : APM OAuth - Auth Server attached iRule works inconsistently

Links to More Info: BT828761

Component: Access Policy Manager

Symptoms:
The iRule attached to the OAuth Resource Server (RS) is not triggered when the traffic hits the virtual server.

Conditions:
The issue occurs during a reboot of the BIG-IP device containing an OAuth server config and an attached iRule, or when the iRule is initially assigned to the OAuth Server.

Impact:
OAuth scope check agent fails with 'HTTP error 503': as the iRule attached to the RS virtual server is not triggered.

Workaround:
For existing OAuth servers with the iRule attached, modify the iRule, for example, adding a log. This makes the iRule trigger when it is initially attached or loaded.

Fix:
The iRule is triggered when a request comes to the OAuth RS virtual server.

Links to More Info: K51011533, BT803965


803109-4 : Certain configuration may result in zombie forwarding flows

Links to More Info: BT803109

Component: Local Traffic Manager

Symptoms:
OneConnect profile in conjunction with 'Source-port preserve-strict' or cmp-hash setting of 'dst-ip' or 'src-ip' on the server-side VLAN may result in zombie forwarding flows.

On the server-side the incoming traffic hits a different TMM from the one that handles the outgoing traffic.

Unexpected 'Inet port exhaustion' messages may be logged in the LTM log file.

Conditions:
-- OneConnect configured.

And one of the following:

-- Source-port is set to preserve-strict.
-- The cmp-hash setting on the server-side VLAN is set to 'dst-ip' or 'src-ip'.

Impact:
Zombie forwarding flows. Over time, the current allocation count grows and does not return to its prior level when traffic stops.

The current allocation can be checked with this command:
# tmctl memory_usage_stat name=connflow -s name,cur_allocs

Workaround:
You can use any of the following workarounds:

-- Remove the OneConnect profile from the Virtual Server.

-- Do not use 'source-port preserve-strict' setting on the Virtual Server.

-- Set the 'cmp-hash default' on the server-side VLAN if it is set to 'cmp-hash src-ip' or 'cmp-hash dst-ip'.

Note: After making this change, it may be necessary to run the command 'tmsh restart sys service tmm', which will clear the old flows but also impact traffic. Traffic interrupted while tmm restarts.

797797-7 : CVE-2019-11811 kernel: use-after-free in drivers

Links to More Info: K01512680, BT797797


794385-6 : BGP sessions may be reset after CMP state change

Links to More Info: BT794385

Component: Local Traffic Manager

Symptoms:
A CMP (Clustered Multiprocessing) state change occurs when the state of the BIG-IP system changes.

This happens in the following instances:
  - Blade reset.
  - Booting up or shutting down.
  - Running 'bigstart restart'.
  - Setting a blade state from/to primary/secondary.

During these events, there is a small chance that ingress ACK packet of previously established BGP connection is going to be disaggregated to the new processing group(TMMs) and selected TMM is ready to process traffic, but is not ready yet to process traffic for existing connection. In this case, connection isn't processed and reset instead.

Conditions:
-- VIPRION chassis with more than one blade.
-- CMP hash of affected VLAN is changed from the Default value, for example, to Source Address.
-- BGP peering is configured.
-- CMP state change is occurred on one of the blades.
-- BGP ingress ACK packet is disaggregated to TMM, which either wrong TMM or not ready to process the packet of already established connection

Impact:
Affected BGP peering is reset and dynamic routes learnt by the configured protocol are withdrawn, making it impossible to advertise dynamic routes of affected routing protocols from the BIG-IP system to the configured peers. This can lead to unexpected routing decisions on the BIG-IP system or other devices in the routing mesh.

In most cases, unexpected routing decisions are from networks learnt by affected routing protocols when the routing process on the BIG-IP system becomes unreachable. However, this state is short-lived, because the peering is recreated shortly after the routing protocol restarts. The peering time depends on the routing configuration and responsiveness of other routing devices connected to the BIG-IP system. It's the usual routing convergence period, which includes setting the peering and exchanging routing information and routes.

Workaround:
There is no workaround, but the issue was never seen with a configuration where CMP hash of affected VLAN is changed back to Default value.

Fix:
BGP session is no longer reset during CMP state change.

14.1.5, 15.1.5.1, 16.1.2.2


755976-9 : ZebOS might miss kernel routes after mcpd deamon restart

Links to More Info: BT755976

Component: TMOS

Symptoms:
After an mcpd daemon restart, sometimes (in ~30% of cases) ZebOS is missing some of kernel routes (virtual addresses).

One of the most common scenario is a device reboot.

Conditions:
-- Dynamic routing is configured.
-- Virtual address is created and Route Advertisement is configured:
imish -e 'sh ip route kernel'
-- mcpd daemon is restarted or device is rebooted.

Impact:
The kernel route (virtual address) is not added to the ZebOS routing table and cannot be advertised.

Workaround:
There are several workarounds; here are two:

-- Restart the tmrouted daemon:
bigstart restart tmrouted

-- Recreate the affected virtual address.

Fix:
The kernel route is now present in the ZebOS routing table after mcpd daemon restart.

749332-1 : Client-SSL Object's description can be updated using CLI and with REST PATCH operation

Links to More Info: BT749332

Component: TMOS

Symptoms:
REST PUT fails to update the object description when proxy-ca-cert and proxy-ca-key are not configured, and triggers an error:
SSL forward proxy RSA CA key is missing.

Conditions:
Issue is seen only with REST PUT operation, and when proxy-ca-cert and proxy-ca-key are not configured.

Impact:
REST PUT operation cannot be used to update/modify the description.

Workaround:
You can use either of the following:

-- You can use TMSH to update/modify the description, even if proxy-ca-cert and proxy-ca-key are not configured.

-- You can also use PATCH operation and send only the required field which need modification.

Fixed Versions:

742753-8 : Accessing the BIG-IP system's WebUI via special proxy solutions may fail

Links to More Info: BT742753

Component: TMOS

Symptoms:
If the BIG-IP system's WebUI is accessed via certain special proxy solutions, logging on to the system may fail.

Conditions:
This issue is known to happen with special proxy solutions that do one of the following things:

- Remove the Referer header.

- Modify the HTTP request in such a way that the Referer and Host headers no longer tally with one another.

Impact:
Users cannot log on to the BIG-IP system's WebUI.

Workaround:
As a workaround, you can do any of the following things:

- Access the BIG-IP system's WebUI directly (i.e., bypassing the problematic proxy solution).

- Modify the proxy solution so that it does not remove the Referer header (this is only viable if the proxy does not alter the Host header).

- Modify the proxy solution so that it inserts compatible Referer and Host headers.

Fix:
CSRF checks based on HTTP headers pre-logon have been improved.

724653-5 : In a device-group configuration, a non-empty partition can be deleted by a peer device during a config-sync.

Links to More Info: BT724653

Component: TMOS

Symptoms:
In a device-group configuration, a BIG-IP administrator can add a non-synced object to a partition on one device, then delete that partition on a peer device, syncing the delete (this is assuming the partition is empty on the peer).

Although the config-sync operation will report as having completed successfully on both devices, and no errors will be visible in the /var/log/ltm file of either device, a number of issues can manifest at a later time.

For instance, assuming the non-synced object was a VLAN, listing all VLANs across all partitions will return the following error:

root@(bigip-ntr-d)(cfg-sync In Sync)(Active)(/)(tmos)# list net vlan recursive
01070712:3: Internal error, can't load folder or nested folder for: /test/my_vlan

And reloading the config will return the following error (as the partition has been deleted, including its flat config files):

root@(bigip-ntr-d)(cfg-sync In Sync)(Active)(/Common)(tmos)# load sys config

01070523:3: No Vlan association for STP Interface Member 1.2.
Unexpected Error: Loading configuration process failed.

These are just examples, and the exact failures will depend on the type of non-synced object and its use within your configuration.

Conditions:
-- Two or more devices in a device-group configuration.
-- Using partitions that contain non-synced objects.
-- Deleting the partition on a device and syncing the changes to the other devices.

Impact:
The partition is deleted on the peer device, even though it still contains non-synced objects. A number of config issues can arise at a later time as a result of this.

Workaround:
In some cases, if you need to define non-synced objects, you can do so in partitions or folders that are associated with 'device-group none' and 'traffic-group none'. This would prevent the partition or folder from synchronizing to other devices in the first place.

Fix:
Validation has been added that will make a config-sync receiver reject the operation if this includes the deletion of a non-empty partition. In this case, the config-sync will fail and report an error message similar to the following example:

0107082a:3: All objects from local device and all HA peer devices must be removed from a partition (test) before the partition may be removed, type ID (467), text ID (60706)

669046-7 : Handling large replies to MCP audit_request messages

Links to More Info: BT669046

Component: TMOS

Symptoms:
When receiving very large replies to MCP messages (e.g., when viewing audit logs from the GUI), MCP can run out of memory and produce a core file. This is due in part to the amount of data returned, and also due in part to memory handling.

In a production environment, fragmentation naturally occurs over the lifetime of MCP, thus increasing the odds of this happening. In addition, larger configurations cause more space to be consumed in MCPD and might more easily lead to the fragmentation, resulting in this issue.

Conditions:
Receiving very large replies to MCP messages (e.g., from audit_request messages, which occurs when you view audit logs from the GUI).

Memory usage is already high.

Impact:
Allocation of memory for viewing the audit logs fails. MCP can run out of memory and produce a core file.

Workaround:
Use tmsh/bash to view the audit logs instead of the GUI when audit logs are extremely large and memory usage is already high.

Fix:
Viewing audit logs in the GUI is now limited to 10,000 lines, so this issue no longer occurs.

Behavior Change:
The GUI is limited to viewing no more than 10,000 lines of the audit log.

You can use tmsh/bash to view audit logs larger than 10,000 lines.

528894-5 : Config-Sync after non-Common partition config changes results in extraneous config stanzas in the config files of the non-Common partition

Links to More Info: BT528894

Component: TMOS

Symptoms:
Configuration stanzas that do not belong in the files of a non-Common partition appear there. These stanzas could include, for example, 'net trunk' or 'sys ha-group' objects.

Conditions:
-- The system includes partitions other than Common.

-- Configuration in a partition other than Common is modified.

-- A Config-Sync operation not involving an overwrite takes place (it is also possible to reproduce this issue on a standalone BIG-IP system by doing a save operation like the following: "tmsh save sys config partitions { Common other }").

Impact:
/config/partitions/<partition_name>/bigip_base.conf will contain extraneous config stanzas (such as the ones mentioned in Symptoms).

/config/bigip_base.conf will no longer contain config stanzas that belong there.

Note that the impact is mostly cosmetic. An affected device will still be able to correctly load its configuration even if some config stanzas appear in the wrong flat config file.

However, Administrators performing audits of the flat config files will be perplexed as to why some stanzas are moving back and forth between partitions.

Workaround:
If you wish to restore your flat config files to their proper state after the issue has already occurred, simply run "tmsh save sys config" on the affected device.

Alternatively, to prevent the issue in the first place, you can Config-Sync using the following command "tmsh run cm config-sync force-full-load-push to-group <device-group>".

Note that neither workaround is permanent and the issue will reoccur.

1087201-6 : OpenSSL Vulnerability: CVE-2022-0778

Links to More Info: K31323265, BT1087201


1084173-1 : Unable to specify "no caching desired" for ephemeral DNS resolvers (i.e. RESOLV::lookup).

Links to More Info: BT1084173

Component: Global Traffic Manager (DNS)

Symptoms:
Each time the iRule command RESOLV::lookup is invoked with a different target IP address or internal virtual server, a unique resolver context is created.

However, for performance and memory preservation reasons, all ephemeral resolvers are backed by the same set of DNS caches.

This means that repeated identical queries to different ephemeral resolvers will always return the answer from the cache that was retrieved by the first ephemeral resolver (until the TTL of the record expires).

While this is fine in the traditional use of DNS, this may be problematic in certain specific use-cases. For example, this does not allow for per-user DNS servers to return different results for the same query. This technique could be used by an iRule to retrieve user-specific information to then spin up user-unique virtual environments.

Conditions:
Sending repeated queries for the same FQDN to different ephemeral resolvers (before the TTL expires) and expecting different results back.

Impact:
Inability to support specific use-cases in a BIG-IP iRule.

Fix:
Versions with the fix include a new DB key called dnscache.ephemeralsnocache, which defaults to "disable".

When set to "disable", the system behaves exactly as in previous releases.

When set to "enable", ephemeral resolvers spawned in an iRule by the RESOLV::lookup command no longer cache anything, thus allowing for use-cases similar to the example mentioned under Symptoms.

Fixed Versions:
16.1.3

1068237-1 : Some attack signatures added to policies are not used.

Links to More Info: BT1068237

Component: Application Security Manager

Symptoms:
Some attack signatures added to an existing signature set may not be utilized by Policies associated with the signature set, despite the attack signatures being reported as now present in the Policies.

Conditions:
1. Have one or more policies utilizing a manual attack signature set.

2. Update the attack signature database by installing an ASU or creating a custom attack signature.

3. Update the previously created manual attack signature set with one or more attack signatures which were not updated by the ASU (if ASU installed) or are not the newly created custom attack signature (if new custom signature created).

Impact:
The additional attack signatures added to the attack signature set will show up in the Policies utilizing the signature set however the Policies will not actually use those additional attack signatures.

Workaround:
There are two workarounds:

1. When adding additional attack signatures to a Policy, place them in a new attack signature set rather than re-using an existing signature set.

2. If adding signatures to an existing set, afterwards create a new custom attack signature, add it to a new manual attack signature set, add the set to any active policy and then remove the set from the policy (the set and signature can then be deleted if desired).

Both workarounds will result in all attack signatures listed as present in all Policies being fully and properly utilized by the Policies.

1064617-1 : DBDaemon process may write to monitor log file indefinitely

Links to More Info: BT1064617

Component: Local Traffic Manager

Symptoms:
If debug logging is enabled for a database monitor (mssql, mysql, postgresql or oracle), the DBDaemon process may write to a monitor log file indefinitely, including after the monitor log file is rotated and/or deleted.

Conditions:
This problem may occur when:
- using a database monitor (mssql, mysql, postgresql or oracle) which is configured with the "debug" value set to "yes"
- using a database monitor (mssql, mysql, postgresql or oracle) for a pool member which is configured with the "logging" set to "enabled"

Impact:
The DBDaemon process may write debug logging messages to the affected monitor log file indefinitely, including after the monitor log file has been rotated and/or deleted.
As a result, storage in the /var/log volume may be consumed to the point that other logging cannot be performed, and the BIG-IP instance may be restarted/rebooted.

Workaround:
To work around this issue, restart the DBDaemon process.

To find the PID of the DBDaemon process, observe the output of the following command:
ps -ef |grep -v grep | grep DB_monitor.jar | awk '{print($2)}'

To confirm whether the DBDaemon process is writing to a monitor log file, and if so, which file:
lsof -p $(ps -ef | grep -v grep | grep DB_monitor.jar | awk '{print($2)}') | grep -e COMMAND -e '/var/log/monitors'

To kill the DBDaemon process:
kill $(ps -ef | grep -v grep | grep DB_monitor.jar | awk '{print($2)}')

NOTE:
Killing the DBDaemon process will cause a short-term loss of database monitoring functionality, until DBDaemon is restarted by the next database monitor probe.

Traffic outage as the affected virtual server(s) no longer passes any traffic.

Workaround:
To recover an affected system, either restart TMM (bigstart restart tmm) or delete and redeploy the iApp service.

To prevent this issue from occurring again, modify the iApp configuration to use the default NTLM profile rather than a custom one (if the iApp template involved allows this).

Fix:
Disabling strict-updates for an iApp service, which includes a non-default NTLM profile, no longer causes virtual servers associated with the profile to suddenly stop working.

1047169-1 : GTM AAAA pool can be deleted from the configuration despite being in use by an iRule.

Links to More Info: BT1047169

Component: TMOS

Symptoms:
A BIG-IP Administrator is incorrectly able to delete a GTM AAAA pool from the configuration, despite this object being referenced in an iRule in use by an AAAA wideip.

An error similar to the following example will be visible in the /var/log/gtm file should the iRule referencing the pool run after the pool has been deleted:

err tmm[11410]: 011a7001:3: TCL error: Rule /Common/my_rule <DNS_REQUEST> - GTM Pool 'my_pool' of type 'A' not found (line 1)GTM Pool 'my_pool' of type 'A' not found (line 1) invoked from within "pool my_pool"

Note the error message incorrectly reports the pool as type A (it should report type AAAA).

Conditions:
-- Two GTM pools of type A and AAAA share the same exact name (which is legal).

-- The pool name is referenced in an iRule by the 'pool' command.

-- The iRule is in use by an AAAA wideip.

-- A BIG-IP Administrator attempts to delete the AAAA pool.

Impact:
The system incorrectly allows the deletion of the AAAA pool from the configuration.

Consequently, the next time the GTM configuration is reloaded from file, the operation will fail.

Additionally, traffic which relied on the pool being present in the configuration will fail.

1046785-1 : Missing GTM probes when max synchronous probes are exceeded.

Links to More Info: BT1046785

Component: Global Traffic Manager (DNS)

Symptoms:
GTM probes are missing, resources are marked down.
When instances fail and BIG-IP is not aware of the failure, some virtual servers/pool members are marked as available and some objects are marked down on part of the sync group members.

In the /var/log/gtm file, the following message may be seen:

011ae116:4: The list processing time (x seconds) exceeded the interval value. There may be too many monitor instances configured with a y second interval

Note that this message is only logged once when gtmd is restarted, or when monitors are added or removed in the gtm configuration.

Conditions:
Max synchronous probes are exceeded. This value is controlled by the GTM global variable max-synchronous-monitor-requests.

Impact:
-- Resources are marked down.
-- Inconsistent monitor statuses across BIG-IP DNS systems in a single sync group
-- Because some monitor instances don't have monitor traffic, if an instance fails, the BIG-IP DNS systems may not be aware of the failure.

Workaround:
Increase the value of Max Synchronous Monitor Requests:

tmsh modify gtm global-settings metrics max-synchronous-monitor-requests value <value - default is 20>

Fix:
All monitors are now allowed to probe without triggering a failure.

1045229-1 : APMD leaks Tcl_Objs as part of the fix made for ID 1002557

Links to More Info: BT1045229

Component: Access Policy Manager

Symptoms:
APMD memory grows over time causing OOM killer to kill apmd

Conditions:
Access policy has resource assignment agents/variable assignments

Impact:
APMD memory grows over time and OOM killer may terminate apmd thereby affecting traffic. Access traffic disrupted while apmd restarts.

If APMD is not killed by OOM killer the system may start thrashing and become unstable, generally resulting in cores from innocent processes that are no longer scheduled correctly - keymgmtd, bigd, mcpd are typical victims.
Ultimately system may restart automatically as watchdogs fail.

1042917-1 : Using 'Full Export' of security policy should result with no diffs after importing it back to device.

Links to More Info: BT1042917

Component: Application Security Manager

Symptoms:
'Declarative policy import' is adding entities into the policy according what it has in the JSON file.

When it imports the policy builder settings, some automatic changes are created in the policy, and it may override other entities which were added before.

1042509-1 : On an HTTP2 gateway virtual server, TMM does not ever update the stream's window for a large POST request

Links to More Info: BT1042509

Component: Local Traffic Manager

Symptoms:
On an HTTP2 gateway virtual server (HTTP/2 on clientside, no httprouter profile), TMM does not update the stream's window (i.e. acking data at the HTTP/2 stream layer). This causes large HTTP requests with payloads (i.e. POSTs) to stall and eventually time out.

TMM does sometimes send WINDOW_UPDATE messages for the entire connection, but not for the stream. Since flow control is required at both the connection and stream levels, the client stalls out.

Conditions:
-- Virtual server with HTTP2 profile
-- Configured as HTTP2 Gateway (HTTP2 profile on clientside and no 'httprouter' profile)
-- Client sends large data transfer to the virtual server

Impact:
Client data transfer through HTTP/2 virtual server (POST / PUT / etc) fails.

Workaround:
Use an HTTP router profile (assign the 'httprouter' profile to the virtual server, or select the 'HTTP MRF Router' option in TMUI)

Fixed Versions:
16.1.2.2

N/A

Fix:
Attack signatures that share words with other attack signatures will be matched correctly now.

Fixed Versions:
13.1.5, 14.1.4.5, 15.1.4.1, 16.1.2.1


1042009-1 : Mcpd fails to reply if a request is proxied to another daemon and the connection to that daemon closes

Links to More Info: BT1042009

Component: TMOS

Symptoms:
Mcpd does not reply to the request if the publisher's connection closes/fails, in this case when bcm56xxd
is restarted. The perceivable signs of the failure are the snmpwalk failing with a timeout and the
"MCPD query response exceeding" log messages

Conditions:
1) Configure snmp on the BIG-IP so you can run snmpwalk locally on the BIG-IP.

2) From one session on the BIG-IP, run a snmpwalk in the while loop.
    
while true;do date; snmpwalk -v2c -c public 127.0.0.1 sysDot1dbaseStat;sleep 2;done

Sample output:

Sat Aug 21 00:57:23 PDT 2021
F5-BIGIP-SYSTEM-MIB::sysDot1dbaseStatResetStats.0 = INTEGER: 0
F5-BIGIP-SYSTEM-MIB::sysDot1dbaseStatMacAddr.0 = STRING: 0:23:e9:e3:8b:41
F5-BIGIP-SYSTEM-MIB::sysDot1dbaseStatNumPorts.0 = INTEGER: 12
F5-BIGIP-SYSTEM-MIB::sysDot1dbaseStatType.0 = INTEGER: transparentonly(2)

3) From a second session on the BIG-IP restart bcm56xxd

bigstart restart bcm56xxd

4a) the snmpwalk will continually report the following:

Timeout: No Response from 127.0.0.1

And snmpd will continually log "MCPD query response exceeding" every 30 seconds in /var/log/ltm

Impact:
SNMP stopped responding to queries after upgrade

Workaround:
Snmpd restart

13.1.5, 14.1.4.6, 15.1.5.1, 16.1.2.2


1040677 : BIG-IP D120 platform reports page allocation failures in N3FIPS driver

Links to More Info: BT1040677

Component: Local Traffic Manager

Symptoms:
Despite having free memory, the BIG-IP system logs kernel page allocation failures to the /var/log/kern.log file. The first line of the output appears similar to the following example:

swapper/6: page allocation failure: order:2, mode:0x204020

After that, a stack trace follows. The process name in the line ('swapper/16', in this example). You may see generic Linux processes or processes specific to F5 in that line.

Conditions:
This issue is known to occur on the appliance D120 (iSeries i15820-DF).

Impact:
As different processes can experience this issue, and the system may behave unpredictably. Software installation may fail.

Workaround:
You can work around this issue by increasing the value of the min_free_kbytes kernel parameter. This controls the amount of memory that is kept free for use by special reserves.

It is recommend to increase this to 128 MB (131072 KB).

When instantiating this workaround, consider whether you want the workaround to survive only reboots, or to survive reboots, upgrades, RMAs, etc. This is an important consideration to make, as you should stop using this workaround when this issue is fixed in a future version of BIG-IP software. So consider the pros and cons of each approach before choosing one.

-- If you want the workaround to survive reboots only, perform the following procedure:

1) Log on to the advanced shell (BASH) of the primary blade of the affected system.

2) Run the following commands (with the desired amount in KB):

# clsh "sysctl -w vm.min_free_kbytes=131072"
# clsh "echo -e '\n# Workaround for ID 851785' >> /etc/sysctl.conf"
# clsh "echo 'vm.min_free_kbytes = 131072' >> /etc/sysctl.conf"

-- If you want the workaround to survive reboots, upgrades, RMAs, etc., perform the following procedure:

1) Log on to the advanced shell (BASH) of the primary blade of the affected system.

2) Run the following commands (with the desired amount in KB):

# clsh "sysctl -w vm.min_free_kbytes=131072"
# echo -e '\n# Workaround for ID851785' >> /config/startup
# echo 'sysctl -w vm.min_free_kbytes=131072' >> /config/startup

Note that the last two commands are not wrapped inside 'clsh' because the /config/startup file is already automatically synchronized across all blades.

Once the issue is fixed in a future BIG-IP version, remove the workarounds:

-- To remove the first workaround:

1) Edit the /etc/sysctl.conf file on the BIG-IP appliance and remove the added lines at the bottom.

2) Reboot the system by running 'clsh reboot'. This will restore the min_free_kbytes kernel parameter to its default value for the BIG-IP version you are running.

-- To remove the second workaround:

1) Edit the /config/startup file on the BIG-IP appliance and remove the extra lines at the bottom.

2) Reboot the system by running 'clsh reboot'. This restores the min_free_kbytes kernel parameter to its default value for the BIG-IP version you are running.

To verify the workaround is in place, run the following command (this should return the desired amount in KB):

# clsh "cat /proc/sys/vm/min_free_kbytes"

Fix:
The BIG-IP system no longer experiences excessive kernel page allocation failures.

Fixed Versions:
16.1.1


1040361-1 : TMM crashes during its startup when TMC destination port list attached/deleted to virtual server.

Links to More Info: BT1040361

Component: Local Traffic Manager

Symptoms:
-- Log message written to TMM log file:
   panic: ../kern/page_alloc.c:736: Assertion "vmem_hashlist_remove not found" failed.

Conditions:
-- Virtual Server using a traffic-matching-criteria (TMC) with a destination-port-list, with multiple distinct ranges of ports.

-- Config changes to virtual server with traffic-matching criteria can cause memory corruption which can lead to delayed TMM crashes.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not use Traffic Matching Criteria with destination port lists.
TMM restart is required in case the virtual server is modified with traffic-matching-criteria related config.

Fix:
TMM no longer crashes under these conditions.

Fixed Versions:
14.1.4.5, 15.1.5, 16.1.2


1039553-1 : Non-200 HTTP status codes fail to be matched by GTM HTTP(S) monitors

Links to More Info: BT1039553

Component: Global Traffic Manager (DNS)

Symptoms:
GTM virtual servers have the wrong status (up when they should be down, or down when they should be up, depending on the monitor's configuration).

Conditions:
-- The GTM virtual servers are monitored with an HTTP or HTTPS monitor that performs HTTP status matching.

-- The monitor tries to match an HTTP status code other than 200 (for example, 301).

-- The monitor uses HTTP version 1.0 or 1.1 for the request (the default is 0.9).

Impact:
The system incorrectly considers all non-200 responses a failed monitor attempt, despite what the user specified as acceptable status codes in the monitor's configuration. As a result, the availability status reported for a virtual server may be incorrect. This may cause the GTM system to send traffic to unsuitable resources causing application disruptions.

Workaround:
You can work around this issue in any of the following ways:

-- Use HTTP version 0.9 for the monitor requests.

-- Match on the 200 HTTP status code.

-- Do not use HTTP status matching altogether.

Fix:
GTM HTTP(S) monitors using HTTP version 1.0 or 1.1 can now successfully match status codes other than 200 in the response.

Fixed Versions:
15.1.5, 16.1.2.1

Links to More Info: BT1038629

Component: Local Traffic Manager

Symptoms:
With the DTLS virtual server, when client sends the CLOSE_NOTIFY alert, BIG-IP is simply closing the connection without sending the CLOSE_NOTIFY back to client as well as the backend server. This causes the backend server to not close/shutdown the connection completely.

Conditions:
This issue occurs with all DTLS virtual servers which has associated client-ssl and server-ssl profiles.

Impact:
Backend server and client will have a dangling connection for certain period of time (Based on the timeout implementation at the respective ends).

1034589-1 : No warning is given when a pool or trunk that was in use by an high availability (HA) Group is deleted from the configuration.

Links to More Info: BT1034589

Component: TMOS

Symptoms:
It is possible to delete a Pool or Trunk from the configuration while one or more high availability (HA) Groups still reference it.

As a result, the configuration of affected high availability (HA) Groups is automatically and silently adjusted (i.e. the deleted object is no longer referenced by any high availability (HA) Group).

The lack of warning about this automatic change could lead to confusion.

Conditions:
A pool or trunk is deleted from the configuration while still being referenced from a high availability (HA) Group.

Impact:
The automatic and silent removal of the deleted object from all high availability (HA) Groups may go unnoticed by BIG-IP Administrators, with potential consequences on the failover behavior of the devices.

1029949-2 : IPsec traffic selector state may show incorrect state on high availability (HA) standby device

Links to More Info: BT1029949

Component: TMOS

Symptoms:
IPsec traffic selector state can be viewed in the config utility or by tmsh with the "tmsh show net ipsec traffic-selector" command. On an high availability (HA) standby device, some selector states may be incorrect.

Conditions:
-- High availability (HA) environment
-- Standby reboots or in some way, such as a tmm restart, is forced to re-learn all the mirrored IPsec security associations (SAs).

Impact:
There is no functional impact. The issue is that a selector may incorrectly appear down in one or both directions.

1029897-1 : Malformed HTTP2 requests can be passed to HTTP/1.1 server-side pool members.

Links to More Info: K63312282, BT1029897

Component: Local Traffic Manager

Symptoms:
The BIG-IP system may pass malicious requests to server-side pool members.

Conditions:
1. The BIG-IP LTM has one or more virtual servers configured to proxy HTTP/2 requests from the client-side to HTTP/1 requests on the server-side.
2. An HTTP/2 client sends a request with one of the following issues and the BIG-IP passes it to the server-side pool members:
a. H2.TE request line injection
   I. An HTTP/1 request embedded within an HTTP/2 pseudo-header value
   II. Individual carriage return (CR) or line feed (LF) allowed within an HTTP/2 pseudo-header
b. Request line injection (folder traps)
c. Request line injection (rule bypass)

Impact:
Malicious HTTP/2 requests can be translated to HTTP/1 requests and sent to the pool member web server. Depending on the behavior of the pool member web server, this can lead to an HTTP request smuggling attack. When the affected virtual server is configured with the OneConnect profile, an attacker might be able to impact the responses sent to a different client.

Workaround:
You can configure the BIG-IP ASM system or Advanced WAF to block an HTTP/1 request that is embedded within an HTTP/2 pseudo header value from being sent to the backend server.

Fix:
This has been fixed so that client requests are appropriately rejected by BIG-IP.

If both IKEv1 and IKEv2 try to listen to the same self IP address on the BIG-IP for a local tunnel IP address, only one can win, and previously a v2 ike-peer would be blocked if a v1 listener managed to get installed first.

If a partial tunnel config exists, with no ike-peer and only ipsec-policy and traffic-selector definitoins, this is understood to be IKEv1 implicitly, by default, and will install a v1 listener for the IP address and port.

Then if a fully configured ike-peer is added using IKEv2, it can fail to establish the required listener for v2 when an existing v1 listener is squatting on that IP address.

Conditions:
Conflict between IKEv2 and IKEv1 on the same IP address when:

-- a v2 ike-peer has local tunnel IP address X

-- a v1 ike-peer, or a traffic-selector with no peer at all, has the same local IP address X

Impact:
An IKEv2 tunnel can fail to negotiate when v2 packets cannot be received on a local IP address because a listener for IPsec cannot be established on that IP address.

Workaround:
You can avoid conflict between v1 and v2 by:

-- removing a traffic-selector not in use (which is v1)

-- avoiding use of the same local IP in both v1 and v2 definitions of ike-peer

Fix:
The fix gives precedence to IKEv2, so any pre-existing IKEv1 listener is simply removed from an IP address whenever a v2 listener is desired for that IP address.

This means IKEv1 can never be negotiated on a local IP address which is also in use by an IKEv2 ike-peer.

Importantly, this fix may cause tunnels to be permanently down after an upgrade. Prior to this change it was possible to have IKEv1 and IKEv2 tunnels working on the same self IP, but in that scenario some tunnels would intermittently fail to establish and the success of the tunnel establishment depended on whether the BIG-IP was the Initiator. IKEv1 and IKEv2 tunnels on the same self IP may still work after this change, but are not considered a valid or supported config by F5.

1024761-1 : HTTP adds Transfer-Encoding and terminating chunk to responses that cannot have a body

Links to More Info: BT1024761

Component: Local Traffic Manager

Symptoms:
When rechunking is requested, HTTP responses with methods or status codes indicating that no body be present (like HEAD or 304) are receiving a Transfer-Encoding header and a terminating chunk. These responses should not have a body of any sort.

Conditions:
HTTP virtual server with rewrite profile present with the server that does HTTP caching.

Impact:
HTTP clients are unable to connect.

Workaround:
Remove the rewrite profile.

Possibly change http profile response-chunking from sustain to unchunk. This resolves the issue for the 304, but means that all other requests are changed from either chunking or unchunked with Content-Length header to unchunked without Content-Length and with "Connection: Close".

1024225-3 : BIG-IP sends "Transfer-Encoding: chunked" to http/2 client after HEAD request

Links to More Info: BT1024225

Component: Local Traffic Manager

Symptoms:
BIG-IP proxying http2 -> http1.1. In response to a HEAD request, pool member sends response with "Transfer-Encoding: chunked" header without chunked payload. BIG-IP sends "Transfer-Encoding: chunked" header back to http2 client which generates RST_STREAM, PROTOCOL_ERROR. According to RFC 7450 a proxy SHOULD remove such headers.

Conditions:
1) H2 <-> H1 is configured on virtual server
2) HEAD request over http2->http1.1 gateway getting chunked response.

Impact:
Http2 connection is reset

Workaround:
iRule to remove "Transfer-Encoding: Chunked" header from response.

Conditions:
Deletion of an expired ike-sa.

Impact:
Restart of tmm and re-negotiation of IPsec tunnels. Traffic disrupted while tmm restarts.

Workaround:
None

Fix:
The internal list data structure has been reorganized to use fewer entities in less-complex relationships. This makes it less likely for a corrupted list to occur, so this issue is less likely to occur.

Fixed Versions:

1022637-1 : A partition other than /Common may fail to save the configuration to disk

Links to More Info: BT1022637

Component: TMOS

Symptoms:
A mismatch between the running-configuration (i.e. what is returned by "tmsh list ...") and the saved-configuration (i.e. what is stored in the flat configuration files) for a partition other than /Common, despite a "tmsh save config" operation was just performed (either by the user or as a result of a config-sync).

Conditions:
- One or more partitions other than /Common exist on the system.

- One or more of said partitions have no more configuration objects defined in them (i.e. are empty).

- A config save operation similar to "tmsh save sys config partitions { Common part1 [...] }" occurs, either manually initiated by an Administrator or as a result of a config-sync operation (in which case the device-group must be configured for manual synchronization).

Impact:
Should a BIG-IP Administrator notice the mismatch, the only immediate impact is confusion as to why the config save operation was not effective.

However, as the flat config files are now out-of-date, performing a config load operation on a unit in this state will resurrect old configuration objects that had been previously deleted.

On an Active unit, this may affect traffic handling. On a redundant pair, there is the risk that the resurrected objects may make it to the Active unit after a future config-sync operation.

Workaround:
If you notice the mismatch, you can resolve it by performing a config save operation for all partitions (i.e. "tmsh save sys config").

Fix:
Non /Common partitions now get saved to disk as intended.

Workaround:
One of the following:

-- Add an HTTP Compression profile to the virtual server, and ensure that 'Keep Accept-Encoding' is not selected.
-- Use an iRule to remove the Accept-Encoding header from requests, e.g.:

ltm rule workaround {
    when HTTP_REQUEST {
        HTTP::header remove Accept-Encoding
    }
}

1020789-4 : Cannot deploy a four-core vCMP guest if the remaining cores are in use.

Links to More Info: BT1020789

Component: TMOS

Symptoms:
When trying to deploy a vCMP guest on an i11800 vCMP host using four or more cores while all of the other cores are in use, the following error message may be seen:

err mcpd[<pid>]: 0107131f:3: Could not allocate vCMP guest (<guest_name>) because fragmented resources

--------------------------------------------------
one more similar issue has raised for 8 guests allocation failure

When trying to deploy a eight core guest on an i11800 vCMP host where four 2 cores are in use, the following error message may be seen:

0107131f:3: Could not allocate vCMP guest (guest-8cores-A) because fragmented resources

Conditions:
-- VCMP provisioned and all or most cores are in use.
-- Attempt to deploy a guest.

This is more likely to occur with vCMP guests that use four or more cores.

Impact:
All of the available cores cannot be used.

Workaround:
You may be able to work around this by deploying the largest guests first, then any remaining 2-core guests.

There is currently no other fix.

Component: Application Security Manager

Symptoms:
The policy versions cleanup process sometimes removes versions in incorrect order. Newer versions are removed while older versions are preserved.

Conditions:
"maxSizeOfSavedVersions" configuration parameter in "/etc/ts/tools/policy_history.cfg" has very low value.

Impact:
Newer versions are removed.

Workaround:

1020705-2 : tmsh show analytics dos-l3 report view-by attack-id" shows "allowed-requests-per-second" instead "attack_type_name

Links to More Info: BT1020705

Component: Application Visibility and Reporting

Symptoms:
Output of "tmsh show analytics dos-l3 report view-by attack-id" command has changed from version 13.x to 15.x. "Attack type" was removed from the system, so it was automatically replaced by the first metric "allowed-requests-per-second". For DOS L3 "Attack type" was replaced by "Vector Name" but it currently is not shown in the report along wit "Attack ID"

Conditions:
AFM is provisioned

Impact:
This change might cause scripts to fail if they use the name of the field.

Workaround:
1) edit /etc/avr/monpd/monp_dosl3_entities.cfg file. Change [dosl3_attack_id] section the following way: add 'vector_name' to measures list and add an additional parameter 'default_measure' as specified below :

[dosl3_attack_id]
...
measures=allowed_requests_per_sec,count,drop_per_sec,drop_count,total_per_sec,total_count,attacks_count,attack_type_name,category_name,vip_name,period,vector_name
default_measure=vector_name
...

2) edit /etc/avr/monpd/monp_dosl3_measures.cfg file. Add in the end the following section:

[vector_name]
id=vector_crc
formula=IF(count(distinct FACT.vector_crc)>1,'Aggregated',attack_vector_str)
merge_formula=IF(count(distinct vector_name)>1,'Aggregated',vector_name)
dim=AVR_DIM_DOS_VIS_ATTACKS_VECTOR
dim_id=attack_vector_crc
tmsh_display_name=vector-name
display_name=Vector
comulative=false
priority=65

3) restart the BIG-IP system: bigstart restart

After the system is up you can apply the same tmsh command: "tmsh show analytics dos-l3 report view-by attack-id"
You will get a result similar to 13.x. Note that "attack_type_name" is replaced by "vector-name"

Fix:
Workaround applied as fix.

Fixed Versions:
14.1.4.4, 15.1.3.1, 16.1.2


1020549-1 : Server-side connections stall with zero window with OneConnect profile

Links to More Info: BT1020549

Component: Local Traffic Manager

Symptoms:
Serverside connections from pool member to BIG-IP hang, with the BIG-IP advertising a TCP zero window.

Conditions:
-- Virtual server with OneConnect profile
-- The BIG-IP applies flow-control to the serverside connection (e.g. the server's response to the BIG-IP is faster than the BIG-IP's forwarding the response to the client)
-- The serverside connection is subsequently re-used

Impact:
Serverside connections hang in the middle of data transfer, and will eventually time out.

Workaround:
If possible, remove the OneConnect profile from the virtual server.

Note: removing a OneConnect profile may cause problems with persistence, as described in
K7964: The BIG-IP system may appear to ignore persistence information for Keep-Alive connections (https://support.f5.com/csp/article/K7964)

Fixed Versions:
16.1.2.2


1020377-1 : Missing IKEv2 listeners can send IKE packets to the IKEv1 racoon daemon

Links to More Info: BT1020377

Component: TMOS

Symptoms:
If an IKEv2 tunnel terminates with an error condition, afterward it is possible for IKE packets to be received by the IKEv1 racoon daemon, which is listening to local host (i.e 127.0.0.1) on ports 500 and 4500.

Conditions:
To get the problem to occur, you may need these details:

-- an IKEv2 config where traffic selector narrowing happens
-- termination of an IKEv2 tunnel with an error condition
-- some other BIG-IP service using the same local self IP

Packets can reach the IKEv1 racoon daemon only when some BIG-IP service uses bigself as the proxy, which forwards packets to localhost (127.0.0.1) with the same port number. So even if no IKEv1 config is present for a local self IP, if some other BIG-IP service also uses bigself as a proxy, this can forward IKE packets to localhost as well.

Impact:
The IKEv2 tunnel does not get renegotiated, because IKE packets reach the IKEv1 daemon, which ignores them, because the proper listener to handle IKEv2 is missing. As a result, tunnel service is interrupted.

Workaround:
Deleting and re-adding the problematic ike-peer and traffic-selector should bring back IPsec support for that tunnel.

If the initiating and responding sides of the tunnel have identical traffic-selector proposals, then narrowing should not happen, and this would also prevent the problem in the first place.

Fix:
BIG-IP systems now manage and handle multiple references to the same listener in a more rigorous way, so the IKEv2 listener cannot go away while it is still needed.

Fixed Versions:
16.1.2

1019357-2 : Active fails to resend ipsec ikev2_message_id_sync if no response received

Links to More Info: BT1019357

Component: TMOS

Symptoms:
In high availability (HA) setup, after failover, the newly active BIG-IP device, will send ikev2_message_id_sync messages to the other device.

If the BIG-IP device did not receive a response, it has to retransmit the packet. Some of the IKE tunnels are trying to retransmitting the packet, but its not going out of BIG-IP due to wrong state of relation between IKE tunnel and connection flow.

After 5 retries, it marks the peer as down, and the IKE tunnel is deleted.

Conditions:
-- High availability (HA) environment
-- IKE tunnels configured
-- A failover occurs

Impact:
Traffic loss.

Workaround:
None

Fix:
Fetch latest connection flow during retransmission of IKE/IPSEC packet.

1018577-4 : SASP monitor does not mark pool member with same IP Address but different Port from another pool member

Links to More Info: BT1018577

Component: Local Traffic Manager

Symptoms:
When the LTM SASP monitor is applied to a pool with multiple members having the same IP Address but different Ports, only one of the pool members with the duplicated IP Address will be monitored (marked UP or DOWN as appropriate). Other pool members sharing the same IP Address will remain in a 'checking' state.

Conditions:
This occurs when using the SASP monitor in a pool with multiple members having the same IP Address but different Ports.
For example:
ltm pool sasp_test_pool {
    members {
        sasp_1:80 {
            address 10.10.10.1
        }
        sasp_1:8080 {
            address 10.10.10.1
        }
        sasp_2:80 {
            address 10.10.10.2
        }
        sasp_2:8080 {
            address 10.10.10.2
        }
    }
    monitor sasp_test
}

In this case, only one pool member with a given IP Address will be correctly monitored by the sasp monitor.
Any additional pool members with the same IP Address but different port will not be monitored by the SASP monitor and will remain in a 'checking' state.

Impact:
Not all pool members may be effectively/accurately monitored by the SASP monitor.

Fix:
The ltm sasp monitor correctly monitors members of a pool which share the same IP Address but different Ports.

Fixed Versions:
13.1.5, 14.1.4.5, 15.1.4.1, 16.1.2


1018493-1 : Response code 304 from TMM Cache always closes TCP connection.

Links to More Info: BT1018493

Component: Local Traffic Manager

Symptoms:
When a virtual server is configured to accelerate HTTP traffic, it caches responses with 200 and 304 response codes. Serving a response with "304 Not Modified" code, TMM may close a connection to a client.

Conditions:
-- A virtual server has a web-acceleration profile (without a web application for versions prior 16.0.0).
-- A response with code 304, stored in TMM cache, is served to a request.

Impact:
A client needs to open a new TCP connection every time when a response with "304 Not Modified" code is served.

Fix:
TMM correctly serves a response with "304 Not Modified" code, allowing to correctly handle TCP connection status.

1018285-2 : MRF DIAMETER to select automatic removal of a persistence entry on completion of a transaction

Links to More Info: BT1018285

Component: Service Provider

Symptoms:
MRF DIAMETER is not DIAMETER-application aware. It does not have application-specific business logic. When creating a DIAMETER solution, BIG-IP operators often need to write iRule scripts that remove a session persistence entry at the end of a transaction.

Conditions:
Some applications require removal of the persistence entry upon successful and unsuccessful completion of a transaction.

root@(bigip1)(cfg-sync Standalone)(Active)(/Common)(tmos)# list ltm rule log_dia_error
ltm rule log_dia_error {

       log local0. "Persistence record delete-on-any"
       DIAMETER::persist delete-on-any
    }
 }
}

Impact:
iRule script is required.

Fix:
DIAMETER::persist irule are supported to remove a persistence entry based on the result status of a answer message.

1018145 : Firewall Manager user role is not allowed to configure/view protocol inspection profiles

Links to More Info: BT1018145

Component: Protocol Inspection

Symptoms:
A user account with the "firewall-manager" role that is assigned permissions only to custom partitions will not be able to configure protocol inspection profiles.

Conditions:
-- A user account is created with the role firewall-manager.
-- A custom partition is created.
-- The newly created user is given access to the newly created partition.

Impact:
Any user account without access to "/Common" partition is not allowed to configure protocol inspection profiles.

Workaround:
- If the user account is provided access to "/Common" partition as well, the user should be able to configure protocol-inspection profiles in the newly created custom partitions.

Fix:
The permissions are granted for any non-admin user to configure protocol inspection profiles in a custom partition as long as they have access to "/Common" partition as well.

1017153-4 : Asmlogd suddenly deletes all request log protobuf files and records from the database.

Links to More Info: BT1017153

Component: Application Security Manager

Symptoms:
Asmlogd suddenly deletes all request log protobuf files and records from the database.

Additionally, after the deletion happens, newly generated event logs seen in database do not show up in TMUI.

Conditions:
-- ASM provisioned
-- Config-sync setup, with frequent sync recovery and/or with a manual-sync device-group with ASM sync enabled.

Impact:
Sudden loss of request logs.

Workaround:
Delete all empty partitions and restart asmlogd.

1) View all the partitions:

   # perl -MF5::Db::Partition -MData::Dumper -MF5::DbUtils -e 'print Dumper(F5::Db::Partition::retrieve_partitions_info(dbh => F5::DbUtils::get_dbh(), table_name => "PRX.REQUEST_LOG"))'

Take note of the 'PARTITION_NAME' and 'TABLE_ROWS' for each partition.

2) For every partition_X (in PARTITION_NAME) with '0' in TABLE_ROWS, delete it by:

   # perl -MF5::Db::Partition -MF5::DbUtils -e 'F5::Db::Partition::delete_partition(dbh => F5::DbUtils::get_dbh(), table_name => "PRX.REQUEST_LOG", partition_name => "partition_X")'

3) restart asmlogd if and after done all deletes:

   # pkill -f asmlogd

NOTE: this workaround is temporary. Meaning, that the number of empty partitions will again accumulate and the same issue will happen again. The MAX number of partitions is - 100. Thus, it is advised to monitor the total number of *empty* partitions and repeat the workaround periodically. A cron script should work well. Normally, empty partitions should NOT accumulate. Thus, it is safe to run this script once an hour and remove all empty partitions.


Optionally, if you are having TMUI issue with newly generated event logs, perform the additional command below to delete rows from PRX.REQUEST_LOG_PROPERTIES for which no corresponding rows exist in PRX.REQUEST_LOG.

# mysql -t -u root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e 'delete from PRX.REQUEST_LOG_PROPERTIES where request_log_id > (select id from PRX.REQUEST_LOG order by id desc limit 1)'

Fix:
Upgrading to a fixed software version will not delete accumulated partitions and will not clear the symptom away. The fix will prevent ASM from accumulating partitions unnecessarily in the scenarios.

If your ASM system is experiencing this and partitions are accumulated, perform the workaround to clear the symptom. Using a fixed software version, you only need to perform the workaround once. You no longer have to perform it periodically.

Fixed Versions:
14.1.4.5, 15.1.4.1, 16.1.2


1016449-3 : After certain configuration tasks are performed, TMM may run with stale Self IP parameters.

Links to More Info: BT1016449

Component: Local Traffic Manager

Symptoms:
A Self IP instantiated by performing specific configuration tasks (see Conditions) does not work (e.g. the system does not respond to ARP requests for it).

On the contrary, the system continues to use (e.g. respond to ARP requests for) an old version of the Self IP specifying a different address.

Conditions:
This issue is known to occur when one of the following operations is performed:

- Restoring a UCS or SCF archive in which a Self IP with a specific name specifies a different address.

- Performing a config-sync between redundant units in which the sender changes a Self IP with a specific name to use a different address. For example:

tmsh delete net self <name>
tmsh create net self <name> address <new_address> ...
tmsh run cm config-sync to_group ...

- Performing specific tmsh CLI transactions involving Self IP modifications.

Impact:
The system does not utilise the configured Self IP address. Traffic will be impacted as a result (for example, in connections to the unit, in snat automap, etc.).

Workaround:
Restart TMM (bigstart restart tmm) on affected units.

Fix:
TMM now correctly handles supported Self IP address modifications.

1016113-1 : HTTP response-chunking 'sustain' profile option may not rechunk responses when also using a web acceleration profile.

Links to More Info: BT1016113

Component: Local Traffic Manager

Symptoms:
Configurations containing HTTP response-chunking 'sustain' and a Web Acceleration profile do not rechunk payload regardless of whether the web server responds with a chunked response.

Conditions:
-- Incoming response payload to the BIG-IP system is chunked.
-- HTTP profile is configured with response-chunking 'sustain'.
-- Web Acceleration profile also configured on the same virtual server.

Impact:
The BIG-IP response is not chunked, regardless of whether the associated web server responds with a chunked payload when the Web Acceleration is utilized.

Workaround:
For a chunked response to be delivered to the client, apply the iRule command 'HTTP::rechunk' to responses when a Web Acceleration profile is used.

Fix:
The BIG-IP response is chunked appropriately when a Web Acceleration profile is used.

1015133-5 : Tail loss can cause TCP TLP to retransmit slowly.

Links to More Info: BT1015133

Component: Local Traffic Manager

Symptoms:
If a long tail loss occurs during transmission, TCP might be slow to recover.

Conditions:
-- A virtual server is configured with the TCP profile attached.
-- SACK and TLP are enabled.
-- A tail loss of multiple packets sent by the BIG-IP occurs.

Impact:
BIG-IP retransmits one packet per RTT, causing a long recovery. The impact is more pronounced if an entire window is lost.

Workaround:
Disabling TLP may improve performance in this particular case, but may degrade performance in other situations.

Fix:

Links to More Info: BT1008849

Component: Application Security Manager

Symptoms:
To fulfill "A4 XML External Entities (XXE)", some required signatures need to be enforced.

Due to an update in some of those attack signatures names, this section does not find the signatures and by mistake it shows that the signatures are not enforced.

Also, when you choose to enforce the required signatures, this section tries to enforce the signatures, but looks for them via the old name, so it does not find them, and can't enforce them.

Conditions:
The attack signatures file is updated with the new names for the XXE signatures.

The old names are in use while trying to find and enforce the signatures, but it does not find them and can't enforce them and also can't see if they are already enforced.

Impact:
"A4 XML External Entities (XXE)" Compliance can't be fully compliant.

Workaround:
N/A

Fix:
The signature ID is being used instead of signature name, and now it can find them and enforce them if needed.

In Virtual Server (/common/my_virtual_server) an http2 profile with enforce-tls-requirements enabled is incompatible with client-ssl/server-ssl profile with renegotiation enabled. Value must be disabled.

Conditions:
BIG-IP system allows this configuration and fails later:

-- Virtual server with HTTP/2, HTTP, and client SSL profiles (with renegotiation disabled).

1. Enable the 'Enforce TLS Requirements' option in the HTTP/2 profile (by default it is enabled).
2. Add server SSL profile with 'TLS Renegotiation' enabled.
3. Save the configuration.
4. Load the configuration.

Impact:
The configuration will not load if saved.

Workaround:
If enabling 'Enforce TLS Requirements' in a HTTP/2 profile configured on a virtual server, ensure that 'TLS Renegotiation' is disabled in the Server SSL profiles on that virtual server.

Fix:
There is now a validation check to prevent this configuration, which is the correct functionality.

Links to More Info: BT1007901

Component: TMOS

Symptoms:
The module provides a service to output module name/identifier and version that can be mapped to the validation records.
The 'tmsh show sys version' command shows a version, but it does not show a module name, where the "module name" is the name on the FIPS certificate.

Conditions:
Running 'tmsh show sys version' while the system is running in FIPS mode

Impact:
The module does not provide a service to output module name/identifier and version that can be mapped to the validation records.

Workaround:
N/A

Fix:
Added the FIPS module information to output of command "show sys version". FIPS module information is now appended after "Project" field info of the "show sys version"

The syntax of the new field is "FIPS Module <FIPS_module_name>"

In the GUI, FIPS module info shall be appended to existing "Version" information shown under system(tab)→Device→Version

1007749-2 : URI TCL parse functions fail when there are interior segments with periods and semi-colons

Links to More Info: BT1007749

Component: Local Traffic Manager

Symptoms:
URI::path, URI::basename, etc., return the wrong strings, e.g., URI::path can return a subset of what it should return.

Conditions:
This happens for URIs like these:
   /alpha/beta/Sample.text;param/trailer/
   /alpha/beta/Sample.text;param/file.txt

Impact:
iRules fail to work as expected for these types of URIs.

This occurs because the combination of the period and semi-colon in 'Some.thing;param' confuses the BIG-IP system parser, causing incorrect results to be returned.

Workaround:
If this is happening for known URIs, then it should be possible to process those URIs in a special way within iRules to do things like temporarily replacing interior periods with another character, like a plus sign.

1007113-3 : Pool member goes DOWN if the time difference between SCTP INIT and SCTP ABORT is less than two seconds

Links to More Info: BT1007113

Component: Service Provider

Symptoms:
In case of diameter over SCTP, while aborting the connection of the pool member, if SCTP INIT is sent by the BIG-IP system before the SCTP ABORT is processed, the pool member is marked UP (provided the SCTP connection is established successfully), and then goes down later, immediately after ABORT is fully processed.

Conditions:
The time difference between SCTP ABORT and SCTP INIT is very small, i.e., 2 seconds or less

Impact:
Pool member is marked DOWN even though it is active

Workaround:
If the watchdog is configured in the diameter session profile (i.e., watchdog-timeout is greater than 0), the pool member is marked UP after DWA is received from the pool member.

Fix:
The system now marks the pool member as UP if DWA is received from the pool member.

Known Issue details for BIG-IP v16.1.x

999881-6 : Tcl command 'string first' not working if payload contains Unicode characters.

Links to More Info: BT999881

Component: Local Traffic Manager

Symptoms:
Tcl command 'string first' returns an incorrect value when Unicode characters are present in the payload.

Conditions:
-- Tcl command 'string first' is used in iRules.
-- Payload contains Unicode characters.

Impact:
Traffic processing with iRules that contains the 'string first' command might not work as expected.

Workaround:
You can use any of the following workarounds:

-- Use iRuleLX.
-- Do not use Unicode characters in the payload.
-- Use a custom Tcl proc to iterate through the string using lindex


999709-6 : iRule 'pool'/'virtual' commands not triggered in CLIENT_ACCEPTED with HTTP/2.

Links to More Info: BT999709

Component: Local Traffic Manager

Symptoms:
The 'pool'/'virtual' iRule commands cause the specified pool to be used directly. However, with HTTP/2, the 'pool'/'virtual' command may fail to execute within the CLIENT_ACCEPTED event. This results in no traffic being sent.

Conditions:
-- A 'pool'/'virtual' command is used under CLIENT_ACCEPTED event.
-- An HTTP/2 profile applied to virtual server.
-- The HTTP/2 protocol in use.
-- HTTP/2 Message Routing is disabled.

Impact:
With HTTP/2 configured, the iRule 'pool'/'virtual' commands fail to execute within the CLIENT_ACCEPTED event, causing no traffic to be sent to the desired pool/virtual.

Workaround:
As a workaround, you may use HTTP_REQUEST event instead of CLIENT_ACCEPTED in iRule syntax.


999669-1 : Some HTTPS monitors are failing after upgrade when config has different SSL option&start;

Links to More Info: BT999669

Component: Local Traffic Manager

Symptoms:
Some HTTPS monitors are failing after upgrade when the config has different SSL option properties for different monitors.

Conditions:
-- Individual SSL profiles exist for different HTTPS monitors with SSL parameters.
-- A unique server SSL profile is configured for each HTTP monitor (one with cert/key, one without).

Impact:
Some HTTPS monitors fail. Pool is down. Virtual server is down.

Workaround:
None


999085-1 : REST endpoint registration errors in restjavad logs

Links to More Info: BT999085

Component: Device Management

Symptoms:
Errors are logged to /var/log/restjavad.0.log at the SEVERE log level:

[SEVERE]... [IcrWorker] Unable to register iControl endpoint "/xxxx/xxxx". Error: uriPath '/tm/xxxx/xxxx' already registered

Conditions:
The system reports these errors during startup of the restjavad service because of multiple registrations of the same endpoint.

Impact:
There is no functional impact and these errors can be ignored.

Workaround:
None


999021-2 : IPsec IKEv1 tunnels fail after a config sync from Standby to Active

Links to More Info: BT999021

Component: TMOS

Symptoms:
When racoon (the IKEv1 daemon) sees a tunnel config change, which occurs due to a config sync from the standby device, the change causes tmm and racoon to have conflicting views on the state of that tunnel.

If the IKEv1 tunnel is up at the time of the config change, tmm fails to restart the tunnel.

Conditions:
-- IPsec IKEv1 tunnel in use.
-- Changes made to IPsec IKEv1 tunnel on the Standby BIG-IP device, which are then sync'd to the Active BIG-IP device.
-- And/or a full config sync from the Standby to Active BIG-IP system.

Impact:
IPsec IKEv1 tunnels fail and do not start again.

Workaround:
-- Do not make changes to IPsec IKEv1 tunnels on the Standby device.

-- Avoid full syncs from Standby to Active.

How to recover when the problem occurs:

-- Disable the affected ike-peer and re-enable it.


998957-1 : Mcpd consumes excessive CPU while collecting stats.

Links to More Info: BT998957

Component: TMOS

Symptoms:
Mcpd CPU utilization is 100%.

Conditions:
This can occur when the BIG-IP system has a large number of virtual servers, pools, and pool members for which statistics are being collected.

Impact:
CPU utilization by mcpd is excessive.

Workaround:
None


998649-1 : Log hostname should be consistent when it contains ' . '

Links to More Info: BT998649

Component: TMOS

Symptoms:
Messages that are logged to journald use the configured hostname, while sylog-ng uses the hostname (machine name) and truncates it starting at the first '.' (period). This results in hostnames being inconsistent when it contains '.'; e.g., 'my.hostname' is logged as 'my' by syslog-ng, and 'my.hostname' by journald. This can make it difficult for log analysis tools to work with the log files.

Conditions:
-- Hostname contains a period
-- Viewing log files emitted from journald and from syslog-ng

Impact:
The full hostname is logged for system logs while logs that go directly to syslog-ng use a truncated hostname.

Workaround:
None.


998253-4 : SNI configuration is not sent via HTTPS when in-tmm monitors are disabled

Links to More Info: BT998253

Component: Local Traffic Manager

Symptoms:
The Server Name Indication (SNI) extension is missing on the HTTPS handshake.

Conditions:
-- Global in-tmm monitors are disabled
-- HTTPS monitor traffic

Impact:
The HTTPS client-server handshake occurs without a TLS SNI.

Workaround:
None


998225-6 : TMM crash when disabling/re-enabling a blade that triggers a primary blade transition.

Links to More Info: BT998225

Component: TMOS

Symptoms:
TMM crashes during the primary blade transition.

Conditions:
-- Using bidirectional forwarding detection.
-- Primary blade transition occurs.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None


997793-3 : Error log: Failed to reset strict operations; disconnecting from mcpd&start;

Links to More Info: K34172543, BT997793

Component: TMOS

Symptoms:
After rebooting the device you are unable to access the GUI. When checking the ltm logs in the SSH / console, it repeatedly prompts an error: tmm crash

Failed to reset strict operations; disconnecting from mcpd.

Conditions:
-- APM provisioned.
-- Previous EPSEC packages that are still residing on the system from earlier BIG-IP versions is installing upon boot.

Impact:
Mcpd fails to fully load and the device fails to come up fully, and it cannot pass traffic.

An internal timer might cause the installation to be aborted and all daemons to be restarted via 'bigstart restart. Traffic disrupted while tmm restarts.

Workaround:
You can recover by restarting the services. Traffic will be disrupted while tmm restarts:

1. Stop the overdog daemon first by issuing the command:
   systemctl stop overdog

2. Restart all services by issuing the command:
   bigstart restart

3. Wait for 10 to 20 mins until EPSEC packages are successfully installed and mcpd successfully starts.


997561-5 : TMM CPU imbalance with GRE/TB and GRE/MPLS traffic

Links to More Info: BT997561

Component: TMOS

Symptoms:
When handling unidirectional GRE traffic, a lack of inner payload entropy can lead to CPU pinning.

In some circumstances, handling this traffic should not require maintaining state across TMMs.

Conditions:
This occurs with GRE/TB (transparent ethernet bridging) and GRE/MPLS traffic.

Impact:
TMM utilization across CPUs is imbalanced, which can impact overall device performance.

Workaround:
None


997541-5 : Round-robin GRE Disaggregator for hardware and software

Links to More Info: BT997541

Component: TMOS

Symptoms:
GRE tunnel traffic is pinned to one CPU.

Conditions:
GRE traffic is passed through BIG-IP system.

Impact:
Traffic is pinned to one CPU and overall performance is degraded.

Workaround:
None


997357-1 : iRule command "SSL:session invalidate" not working as expected

Links to More Info: BT997357

Component: Local Traffic Manager

Symptoms:
The iRule command "SSL:session invalidate" allows session resumption to happen. Session resumption not supposed to occur when this iRule command is used in an iRule.

Conditions:
"SSL:session invalidate" is used in the iRule event HTTP_REQUEST

Impact:
Session resumption would happen where the iRule is used with "SSL:session invalidate" included which is not supposed to occur

Workaround:
Session resumption should be disabled in SSL profiles


996985-1 : No IP address format validation while adding IP addresses in IPv4 LAN Address Space or IPv4 Exclude Address Space when configuring Network Access Resource.

Links to More Info: BT996985

995097-1 : Certain management-dhcp supersede options fail to restore correctly when the configuration is reloaded from a file.

Links to More Info: BT995097

Component: TMOS

Symptoms:
After reloading the configuration from a file, management-dhcp supersede options whose values contained a double quote character (") no longer contain the character.

For instance, after reloading the configuration, the following section:

# tmsh list sys management-dhcp sys-mgmt-dhcp-config supersede-options
sys management-dhcp sys-mgmt-dhcp-config {
    supersede-options {
        domain-name {
            value { "example.com" }
        }
        domain-name-servers {
            value { 8.8.8.8 }
        }
        domain-search {
            value { "example.com" }
        }
    }
}

Becomes:

# tmsh list sys management-dhcp sys-mgmt-dhcp-config supersede-options
sys management-dhcp sys-mgmt-dhcp-config {
    supersede-options {
        domain-name {
            value { example.com }
        }
        domain-name-servers {
            value { 8.8.8.8 }
        }
        domain-search {
            value { example.com }
        }
    }
}

This also affects the configuration file for the dhclient/dhclient6 daemons that the system automatically generates from the aforementioned config stanza.

Conditions:
This issue occurs when the following statements apply:
--- The values of management-dhcp supersede options contain double quote characters.
--- The configuration is reloaded from file.

The BIG-IP system reloads the configuration from file in the following cases:
-- When you issue the 'tmsh load sys config' command.
-- After an upgrade, as the mcpd binary database does not exist yet.
-- When troubleshooting requires removing the mcpd binary database and reloading the config from file.
-- When the system is relicensed.
-- When system provisioning changes.
-- When a UCS/SCF archive is restored.
-- When someone merges in config from file or terminal (but this is limited to the actual contents being merged in, not the entire configuration).

Impact:
The in-memory mcpd configuration relating to management-dhcp supersede options is incorrect.

The /etc/dhclient.conf file that is automatically generated contains incorrect syntax.

As a result of this, the dhclient/dhclient6 daemons fail to parse the file and run with an incomplete configuration.

Ultimately, the system does not behave as configured in regard to its management-dhcp configuration.

Workaround:
Reapply the desired management-dhcp supersede-options configuration using the tmsh utility.

For example, to restore the intended in-memory configuration shown under Symptoms, you would run within tmsh:

# modify sys management-dhcp sys-mgmt-dhcp-config supersede-options none
# modify sys management-dhcp sys-mgmt-dhcp-config supersede-options add { domain-search { value add { \"example.com\" } } }
# modify sys management-dhcp sys-mgmt-dhcp-config supersede-options add { domain-name { value add { \"example.com\" } } }
# modify sys management-dhcp sys-mgmt-dhcp-config supersede-options add { domain-name-servers { value add { 8.8.8.8 } } }
# save sys config

On versions earlier than 15.0.0, you must also restart the dhclient/dhclient6 daemons by running:

bigstart restart dhclient dhclient6

Note that the workaround is not permanent and will be invalidated the next time the config is loaded from file again.


994985-3 : CGNAT GUI shows blank page when applying SIP profile

Links to More Info: BT994985

Component: Carrier-Grade NAT

Symptoms:
The virtual server properties GUI page shows blank when a SIP profile is applied to the virtual server.

Workaround:
None.


994365-1 : Inconsistency in tmsh 'object mode' for some configurations

Links to More Info: BT994365

Component: TMOS

Symptoms:
Tmsh does not support object mode when modifying certain configurations, such as the node configuration. This results in misleading error 'not found' even though the configuration is available.

Conditions:
Modify node config results in error, even though the config is present.

# Node Object 'example' is created successfully
(tmos)# create ltm node example address 1.2.3.4

# On modifying the node 'example', tmsh gives error
(tmos)# modify ltm node example
      Data Input Error: node "example" not found

The modify command does work when a property is specified:
(tmos)# modify ltm node example description "Node 1234"

Impact:
Inconsistent tmsh syntax when using 'object mode' for modifying the configuration.

Workaround:
Use 'tmsh modify' commands, or the GUI, to make the required changes without 'entering' the object in tmsh.


994361-2 : Updatecheck script hangs/Multiple updatecheck processes

Links to More Info: BT994361

Component: TMOS

Symptoms:
Multiple updatecheck and 'rpm -qf' processes running simultaneously.

Updatecheck is not functional

Conditions:
Updatecheck is run periodically via a cronjob. Updatecheck runs 'rpm -qf' command.

Impact:
Due to that 'rpm -qf' command hangs. This causes multiple updatecheck and 'rpm -qf' processes. High CPU and memory usage.

The most likely explanation is that rpmdb has gotten corrupted.

Workaround:
To rebuild rpmdb:

1. Halt all running updatecheck and 'rpm -qf' processes.

2. Run these commands:
rm /var/lib/rpm/__db*
rpm --rebuilddb

993269-3 : DoS timestamp cookies are incompatible with FastL4 TCP timestamp rewrite option

Links to More Info: BT993269

Component: Advanced Firewall Manager

Symptoms:
Using DoS timestamp cookies together with a FastL4 profile with the timestamp rewrite option enabled might lead to traffic failures.

DoS timestamp cookies might also lead to problems with traffic generated by the Linux host.

Conditions:
-- DoS timestamp cookies are enabled, and either of the following:

-- FastL4 profile with the timestamp rewrite option enabled.

992813-7 : The list of dhcp-options known to mcpd is outdated, leading to the inability to instantiate certain management-dhcp configurations.

Links to More Info: BT992813

Component: TMOS

Symptoms:
The mcpd daemon performs validation of the request-options and supersede-options a BIG-IP administrator specifies via the tmos.sys.management-dhcp endpoint in tmsh.

As the list of dhcp-options known to mcpd is outdated, it is possible you may be returned an error when attempting to configure valid request-options or supersede-options.

For example, you may be returned the following error when attempting to supersede the domain-search option:

01071627:3: Management Dhcp resource supersede-option - Invalid dhcp option: domain-search

Conditions:
You attempt to configure a dhcp-option unknown to mcpd as part of the request-options or supersede-options properties.

Note: A common dhcp-option of which mcpd has no knowledge is domain-search. You are unlikely to experience this issue unless you are requesting or superseding this particular dhcp-option.

Impact:
You are unable to instantiate the desired management-dhcp configuration.

Workaround:
None

991265-3 : Persistence entries point to the wrong servers for longer periods of time

Links to More Info: BT991265

Component: Local Traffic Manager

Symptoms:
Persistence entries point to the wrong servers for a longer than expected.

Conditions:
A pool member goes down, causing the persistence entry to change to a new pool member. Then, the pool member comes back up.

Impact:
The persistence entry does not change to the pool member that came back up. It does not expire as client requests using this cookie continue to refresh the persistence entry that goes to the wrong server.

This can delay recovery of the pool members when they are marked down for regular maintenance, or if all pool members are cycled up/down periodically, it causes persistence entries to point to the wrong servers for longer periods of time than necessary.

Workaround:
None.

990853-1 : Mcpd restarts on Secondary VIPRION blades upon modifying a vCMP guest's management IP address or gateway.

Links to More Info: BT990853

Component: TMOS

Symptoms:
The mcpd daemon restarts on all secondary VIPRION blades after logging error messages similar to the following example to the /var/log/ltm file:

-- err mcpd[6250]: 0107098a:3: The ip address (10.10.10.3%1) for a VCMP Mgmt IP in partition () references a route domain (1) in a different partition (part1). Objects may only reference objects in the same or the 'Common' partition
-- err mcpd[6250]: 01070734:3: Configuration error: Configuration from primary failed validation: 0107098a:3: The ip address (10.10.10.3%1) for a VCMP Mgmt IP in partition () references a route domain (1) in a different partition (part1). Objects may only reference objects in the same or the 'Common' partition... failed validation with error 17238410.

Conditions:
-- Multi-blade VIPRION system provisioned as vCMP host.
-- The system is configured with partitions using non-default route-domains.
-- Using the GUI, an Administrator attempts to modify the management IP address or management gateway of a vCMP guest.
-- A non-Common partition is selected in the GUI Partition drop-down menu when making the change.

Impact:
MCPD restarts, causing all other daemons on the blade to restart as well. The vCMP guests running on the affected blades suffer an outage and are unable to process traffic while the daemons restart.

Workaround:
Ensure that when you make management IP address or gateway changes to a vCMP guest, you do so while the Common partition is selected in the GUI.


990173-1 : Dynconfd repeatedly sends the same mcp message to mcpd

Links to More Info: BT990173

Component: Local Traffic Manager

Symptoms:
If dynconfd sends a single message to mcpd containing two or more operations, and one of the operations fails mcpd validation, dynconfd repeatedly sends same message to mcpd.

An example of two operations in one mcp message would be an ephemeral node creation and an ephemeral pool member creation in a single mcp message.

Conditions:
This can occur when:

-- Using FQDN nodes and FQDN pool members.

-- There is an additional issue where the message from dynconfd fails validation within mcpd (e.g., a misconfiguration in which the monitor assigned to the pool is configured with a wildcard destination and the pool member is added to the pool with a port of '0' or 'any'.

Impact:
By repeatedly resending the same messages, which fail repeatedly, dynconfd causes increased mcpd CPU utilization.

This might cause the population of ephemeral nodes and pool members to fail and become out of sync with what the DNS server is resolving.

Workaround:
Examine the LTM logs for mcpd error messages indicating failed attempts to create ephemeral nodes or ephemeral pool members, and resolve the cause of the failed node or pool-member creation.


989937-2 : Device Trust Certificates Expiring after 2038-01-19 show date of 1969

Impact:
Increased resource usage and excessive logging.

Workaround:
None.


989517-3 : Acceleration section of virtual server page not available in DHD

Links to More Info: BT989517

Component: TMOS

Symptoms:
Cannot use Advanced Menu to create a virtual server for HTTP/2 on systems with DHD licenses. This occurs because the Acceleration section is not available.

You can via TMSH then it works, but at as soon as you use the GUI to modify the virtual server, it loses the HTTP/2 configuration.

Conditions:
The Acceleration section is not visible in case 'DoS' is provisioned (available with the DHD license).

Impact:
1) You are unable to use the GUI to modify any parameters of the Acceleration table in the virtual server page.

2) Loss of configuration items if making changes via the GUI.

Workaround:
A virtual server with parameters present in the Acceleration table can still be created using TMSH. However, do not edit that virtual server in the GUI, or the Acceleration parameters will be lost.

987081-1 : Alarm LED remains active on Secondary blades even after LCD alerts are cleared

Links to More Info: BT987081

Component: TMOS

Symptoms:
When a condition occurs which causes an alert message to be logged to the LCD display for a VIPRION chassis, the Alarm LED on the blade where the condition was reported may be set (to solid or flashing amber or red) according to the severity of the reported condition.

When the LCD alert messages are cleared, the Alarm LED on the Primary blade in the chassis will be cleared (or set according to remaining alert messages if only a subset of messages are cleared).

However, the Alarm LED on the Secondary blades in the chassis will not be cleared, and will continue to indicate the highest severity of the previously reported alert messages.

Conditions:
This occurs when:
-- A condition is reported by a Secondary blade in the chassis which causes its Alarm LED to be set (to solid or flashing amber or red) and a message logged to the chassis LCD display.
-- The LCD alert messages are cleared, such as by issuing the 'tmsh reset-stats sys alert lcd' command.

Impact:
The Alarm LED on one or more Secondary blades in the chassis continues to indicate an alert condition even after the previously reported alert messages have been cleared.

Workaround:
To restore the Secondary blade LEDs to their proper state, restart the fpdd daemon on each affected blade.

For example, if the Alarm LED is not reset on the blade in slot 4, issue one of the following commands from the console of the Primary blade in the chassis:
-- clsh --slot=4 "bigstart restart fpdd"
-- ssh slot4 "bigstart restart fpdd"

Alternately, you may log in to the console of the affected blade and issue the 'bigstart restart fpdd' command directly.

985925-3 : Ipv6 Routing Header processing not compatible as per Segments Left value.

Links to More Info: BT985925

Component: Local Traffic Manager

Symptoms:
Packet should forward the packet with the route header unmodified when Segments Left is 0 (zero). It performs as expected when Segments Left is non-zero by dropping the packet and sending an ICMP error.

Conditions:
-- An IPv6 packet whose Next Header in IP header is Routing Header IPv6.
-- In the Routing Header IPv6 header, the Type field is 0.
-- In the Routing Header IPv6 header, the Segment Left field is 0.

Impact:
With Next Header field in IP header being Routing Header for IPv6, BIG-IP system fails to forward the ICMPv6 Echo Request packet to server, rather, it drops the packet.

Workaround:
None

984897-1 : Some connections performing SSL mirroring are not handled correctly by the Standby unit.

Links to More Info: BT984897

Component: Local Traffic Manager

Symptoms:
Some of the connections performing SSL mirroring do not advance through TCP states as they should on the Standby unit.

Additionally, these connections do not get removed from the connection table of the Standby unit when the connections close. Instead, they linger on until the idle timeout expires.

Conditions:
A virtual server configured to perform SSL connection mirroring.

Impact:
Should the units fail over, some connections may not survive as expected.

Additionally, given a sufficient load and a long idle timeout, this could cause unnecessary TMM memory utilization on the Standby unit.

Workaround:
None.

984521-4 : Accept-Encoding header is stripped by Bot Defense profile in case of incompatible file extension and a dot in the file name

Links to More Info: BT984521

Component: Application Security Manager

Symptoms:
Bot Defense profile checks if a page is not an HTML page by checking the file extension (among other ways).

In case the filename contains a dot (.) - the parsing is wrong and it is not detected as incompatible. As a result, the Accept-Encoding header is removed (to allow injection in the response).

Conditions:
-- Bot Defense profile is attached to s virtual server configured with any response injection (Device ID, Browser Verification, or Single Page Application).
Request is sent to an incompatible file extension (one of gif,png,bmp,jpg,ico,css,mp3,mp4,mpg,avi,wmv,mov,3gp,fla,swf,js), and filename contains a dot (.).

Impact:
Accept-Encoding header is removed, causing the server to not send a gzipped response.

Workaround:
Add this specific URL to sys db:

dosl7.parse_html_excluded_urls


984449-2 : Unnecessary swagger validation violation may raise due to behavioral WAF parameter traps that have identical name

Links to More Info: BT984449

Component: Application Security Manager

Symptoms:
An unnecessary swagger validation violation may be raised about illegal parameters which is actually the parameter trap that was injected by ASM and failed to be ignored by the enforcer. Only one of these parameter traps will be ignored - enforcement will be avoided for it. Expected behavior is to avoid enforcement for both parameters traps.

Conditions:
Security team provide 2 traps with type parameter and with identical name but with different values. In adition one of these parameter traps was injected by ASM to the web-page.

Impact:
Unecessary swagger validation violation may raise regarding one of these parameters traps and request may be blocked, instead of ignoring swagger enforcement for both parameters traps.

976525-5 : Transparent monitors can have the incorrect source address when snat.hosttraffic is enabled

Links to More Info: BT976525

Component: Local Traffic Manager

Symptoms:
In BIG-IP v13.1.3.2 and later, there is new functionality to SNAT the traffic coming from the host system. When there are multiple routes to a destination address and transparent monitors are in use, tmm occasionally picks the wrong source IP for these connections.

Conditions:
-- The db variable snat.hosttraffic is enabled.
-- Gateway pool with multiple members.
-- Transparent monitors.

Impact:
The system chooses the wrong source IP address for the egress interface. That incorrect source IP address might cause traffic to return on the wrong VLAN.

Workaround:
Use either of the following workarounds:

-- Disable VLAN keyed connections: modify sys db connection.vlankeyed value disable

-- Upgrade to a version with a fix for ID 826905 (https://cdn.f5.com/product/bugtracker/ID826905.html) and disable snat.hosttraffic.


976517-2 : Tmsh run sys failover standby with a device specified but no traffic group fails

Syntax Error: There is no failover device with a name (/Common/bigip2.localhost).

Conditions:
Two or more BIG-IPs configured with high availability (HA)

Impact:
You are required to specify all the traffic groups you want to failover to a peer.

Workaround:
For each traffic group that you want to failover to a peer run the tmsh run /sys failover standby.

For example if you want to fail over both traffic groups traffic-group-1 and traffic-group-2 to failover to bigip2.localhost, run the following:

tmsh run /sys failover standby device bigip2.localhost traffic-group traffic-group-1

tmsh run /sys failover standby device bigip2.localhost traffic-group traffic-group-2

If you want the device to be standby for all traffic groups but you don't care what device takes over as active, run the following command (note there is no traffic-group nor device):

tmsh run /sys failover standby

969553-1 : A DNS Cache (or Network DNS Resolver) returns SERVFAIL to some queries.

Links to More Info: BT969553

Component: Global Traffic Manager (DNS)

Symptoms:
- A DNS Cache (or Network DNS Resolver) returns SERVFAIL responses to clients, despite the BIG-IP system receiving a good (albeit delayed) response from upstream servers.

- When this happens, the BIG-IP system rejects the responses from the upstream servers with ICMP errors (Destination unreachable - Port unreachable).

- If the db key dnscacheresolver.loglevel is set to debug5, the following error message is visible in the /var/log/ltm file when this issue occurs:

debug tmm[13147]: DNScache: request example.com. has exceeded the maximum number of glue fetches 17 to a single delegation point

- If a Network DNS Resolver is used with an HTTP Explicit Proxy profile, the symptoms can appear as "503 Service Unavailable" responses to clients due to DNS lookup failure.

Conditions:
This issue occurs when the following conditions are met:

- A DNS Cache (or Network DNS Resolver) is in use on the BIG-IP system.

- The aforementioned object is configured with a forward-zone that uses multiple servers to perform resolutions.

- The RTT of the servers fluctuates. For example, the servers are generally fast to reply for most domains, but take extra time to reply for a given domain.

- 'Randomize Query Character Case' is enabled in the DNS Cache (or Network DNS Resolver).

- If the requests for the domain take a long time to resolve, BIG-IP may reply with SERVFAIL.

Impact:
Clients of the BIG-IP DNS Cache (or Network DNS Resolver) are not returned an answer. As a result, application failures may occur.

Workaround:
You can work around this issue by changing 'Randomize Query Character Case' to 'No' in the DNS Cache (or Network DNS Resolver) settings.

966949-6 : Multiple FQDN ephemeral nodes not deleted upon deleting FQDN template node

Links to More Info: BT966949

Component: TMOS

Symptoms:
If an FQDN template node is configured with "autopopulate enabled" and the FQDN name resolves to multiple IP addresses, multiple FQDN ephemeral nodes will be created.
If the FQDN template node is then deleted, the associated FQDN ephemeral nodes (sharing the same FQDN name) will not be deleted as expected.

Conditions:
This may occur under the following conditions:
-- An FQDN template node is configured with "autopopulate enabled"
-- The configured DNS server resolves the FQDN name to multiple IP addresses
-- You are running an Affected Version of BIG-IP, or an Engineering Hotfix based on a non-Affected Version of BIG-IP which contains a fix for ID 722230

This issue does not occur if only one FQDN ephemeral node is created for the associated FQDN template node.

Impact:
Unused FQDN ephemeral nodes may remain in the active configuration.
-- Since is it not possible to delete an FQDN template node if there are any FQDN template pool members referring to that node, it is not possible for any FQDN ephemeral pool members to remain when the steps that lead to this issue occur.
-- Since traffic can only be passed to FQDN ephemeral pool members, the existence of the unused FQDN ephemeral nodes does not lead to traffic being passed to such nodes.

Workaround:
It is possible to work around this issue by one of the following methods:
-- Manually deleting the remaining FQDN ephemeral nodes using the "tmsh" command-line interface (CLI)
(Note that this is normally not possible. It is possible to manually delete an FQDN ephemeral node only if the corresponding FQDN template node no longer exists.)
-- Restarting BIG-IP (for example, using the command "bigstart restart")

Workaround:
0) If the /appdata partition is filled to 100% and MySQL restarts continuously, refer to the following Knowledge Articles:
   https://support.f5.com/csp/article/K14956
   https://support.f5.com/csp/article/K42497314

1) To identify the empty partitions, look into:
   SELECT * FROM INFORMATION_SCHEMA.PARTITIONS WHERE table_name = 'REQUEST_LOG' AND table_schema = 'PRX'\G

2) For every partition that is empty, manually (or via shell script) execute this sql:
   ALTER TABLE PRX.REQUEST_LOG DROP PARTITION empty_partition_name
where 'empty_partition_name' is the partition name as 'p100001'

4) Increase 'open_files_limit' to '10000'.
--------------------------------
In the /etc/my.cnf file:
1. Change the value of the 'open_files_limit' parameter to 10000.
2. Restart MySQL:
   bigstart restart mysql
--------------------------------

5) pkill asmlogd

Note: This workaround does not survive upgrade. It must be reapplied after every upgrade until the upgraded version contains a fix.


959613-1 : SIP/HTTPS monitor attached to generic-host virtual server and pool shows 'blank' reason

Links to More Info: BT959613

Component: Global Traffic Manager (DNS)

Symptoms:
When you double-monitor a Generic Host Virtual Server (pool level + virtual server level) using the same SIP/HTTPS monitor, the 'Reason' is omitted from the output. 'tmsh show gtm server <server> virtual-servers' shows a "blank" reason for monitoring failure/success.

Conditions:
Double-monitor a Generic Host virtual server (pool level + virtual server level) using the same SIP/HTTPS monitor.

Impact:
Impedes your ability to identify the failure/success reason quickly.

Workaround:
Do not use the same monitor on both the virtual server and the pool level.


959241-1 : Fix for ID871561 might not work as expected on the VCMP host

Links to More Info: BT959241

Component: TMOS

Symptoms:
Attempting to deploy an engineering hot fix (EHF) for ID871561 (https://cdn.f5.com/product/bugtracker/ID871561.html) fails in the same manner

Conditions:
-- Attempting to install an EHF containing a fix for ID871561 on a vCMP guest
-- The fix for ID871561 has not already been applied to the vCMP guest

Impact:
Unable to perform software installations on vCMP guests using installation media located on the vCMP host even if fix for ID871561 is available on VCMP guest.

Workaround:
Option 1:
===========
Make sure that the .iso files for both base image and engineering hotfix are copied to the vCMP guest (under /shared/images) before starting the installation. If installing the software from the command line, use syntax similar to the following:

tmsh install sys software hotfix <hotfix-image-name> volume <volume.name>

Option 2:
===========
Even if the engineering hotfix installation has failed, the base image should still have been installed properly. You can restart the vCMP guest and perform a hotfix installation on top of already installed base image, using syntax similar to the following:

tmsh install sys software hotfix <hotfix-image-name> volume <volume.name>

Option 3:
===========
Even if the engineering hotfix installation has failed, the base image should still have been installed properly. Ensure there is copy of the engineering hotfix image locally within the vCMP Guest.

Then restart the lind service on the vCMP Guest:
  tmsh restart sys service lind

If running the vCMP Guest on multiple slots, you may need to restart lind on all slots. From the primary slot on the vCMP Guest, run:
  clsh tmsh restart sys service lind

The hotfix installation should begin again, this time using the hotfix from within the /shared/images/ location on the vCMP Guest.

Option 4:
===========
Manually eject the CD from the vCMP guest's virtual CD drive, and then restart lind. On the vCMP Guest:

1. Confirm the wrong ISO image is still locked (inserted in the CD drive):
  isoinfo -d -i /dev/cdrom

Note: Pay attention to the volume ID in the output from within the vCMP guest.

2. Unlock (eject) the image:
  eject -r -F /dev/cdrom && vcmphc_tool -e

3. Verify the CD drive is now empty:
  isoinfo -d -i /dev/cdrom

The output should report an error that includes:
<...> Sense Code: 0x3A Qual 0x00 (medium not present) Fru 0x0 <…>

4. Restart lind:
  tmsh restart sys service lind

If running the vCMP Guest on multiple slots, you may need to restart lind on all vCMP Guest slots. From the primary slot on the vCMP Guest, run:
  clsh tmsh restart sys service lind

956645-4 : Per-request policy execution may timeout.

Links to More Info: BT956645

Component: Access Policy Manager

Symptoms:
When attempting to access a resource that requires subsession validation, the client may receive an HTTP 503 "Service Unavailable" response, and the logs indicate that per-request policy execution time has expired.

Conditions:
Multiple connections are accessing the same subsession, triggering subsession lock contention.

Impact:
Some clients will fail to connect to their destination.

Workaround:
Add criteria to the gating criteria to enable more fine-grained subroutines to reduce subsession contention. For example, add category, or application name, to the gating criteria. In the case of API protection, consider concatenating credentials with the resource hostname (plus port).

Increase the per-request policy execution timeout value, controlled by the variable tmm.access.prp_global_timeout, to a higher value.

956109-4 : Modifying a traffic-matching-criteria with a port-list during a full sync may result in an incorrect configuration on the sync target

Links to More Info: BT956109

Component: Local Traffic Manager

Symptoms:
In a device service cluster, changing a traffic-matching-criteria object's port configuration and then performing a full-sync will cause the sync target's traffic-matching-criteria ports to be modified incorrectly.

Once systems are in this state, further ConfigSyncs may result in these error messages:

err mcpd[6489]: 01070710:3: Database error (13), Cannot update_indexes/checkpoint DB object, class:traffic_matching_criteria_port_update status:13 - EdbCfgObj.cpp, line 127.

Conditions:
-- Two or more BIG-IPs in a DSC.
-- Using traffic-matching-criteria, and making changes.

Impact:
BIG-IP configurations are out of sync (even though they show "In Sync"). Affected virtual servers will process more traffic than configured.

Workaround:
On an affected system, perform one of the two procedures to correct MCPD's in-memory configuration:

1. Remove the traffic-matching criteria from all virtual servers (or only affected virtual servers, if known), and then re-add the traffic-matching criteria.

2. Save the configuration and then follow the procedure in

2. 1. NULL Value for attribute . Example in tcpdump taken on affected user :

vals: 1 item
    AttributeValue: 00

Impact:
Logging in via the GUI will fail silently
Logging in via ssh will cause the sshd service on LTM to crash and logs will be seen under /var/log/kern.log

The logs will be similar to :

info kernel: : [460810.000004] sshd[31600]: segfault at 0 ip 00002b3abcb2ef3e sp 00007fffef3431a0 error 4 in pam_ldap.so[2b3abcb2c000+7000]
info kernel: : [460810.002036] traps: sshd[31598] general protection ip:fffffffffffffff3 sp:80000 error:0

Workaround:
There is no Workaround on the LTM side.

For LDAP, you change/add the value from none/NULL on the affected attribute to ANY dummy value which will prevent the issue

947125-7 : Unable to delete monitors after certain operations

Links to More Info: BT947125

Component: Local Traffic Manager

Symptoms:
Unable to delete monitor with an error similar to:

01070083:3: Monitor /Common/my-mon is in use.

Conditions:
-- Monitors are attached directly to pool members, or node-level monitors exist.
-- Performing an operation that causes the configuration to get rebuilt implicitly, such as "reloadlic".

Impact:
Unable to delete object(s) no longer in use.

Workaround:
When the system gets into this state, save and reload the configuration:
tmsh save sys config && tmsh load sys config


945413-2 : Loop between keymgmtd and mcpd causes BIG-IP to be out of sync or in constant automatic config sync

Links to More Info: BT945413

Component: TMOS

Symptoms:
The BIG-IP system constantly downloads the certificate bundle if the CA-bundle manager config includes a URL.

Symptoms are different depending on if BIG-IP systems is in a manual or automatic sync device group.

Manual sync device groups will not stay in sync.

Automatic sync device groups will constantly sync.

Conditions:
The CA-bundle manager is configured.

Impact:
The keymgmtd and mcpd process gets into a loop that causes constant config changes and if the ca-bundle-manager includes a URL, the BIG-IP system constantly downloads the bundle.


945189-5 : HTTPS monitor fails due to missing ECDHE-RSA-AES256-CBC-SHA&start;

Links to More Info: BT945189

Component: Local Traffic Manager

Symptoms:
After upgrade, the 'DEFAULT' cipher in the server SSL profile attached to the HTTPS monitor does not include the ECDHE-RSA-AES256-CBC-SHA cipher suite in the Client Hello.

Conditions:
After upgrade, HTTPS monitor cipherlist is read from server SSL profile ciphers and set to DEFAULT after upgrade.

Impact:
1. Upgrade breaks the SSL pool monitoring.
2. It is also possible that the pools monitoring succeeds but with different ciphers

That can cause multiple issues:

2a. After upgrade, the ciphers are of a lower strength, and now the traffic is vulnerable to attacks
2b. After upgrade, the ciphers are of a higher strength, causing BIGD overload up to control plane crashes and device reboots

Workaround:
Set ciphers as DEFAULT:+SHA:+3DES:+EDH for profile server-ssl

Links to More Info: BT942217

Component: Local Traffic Manager

Symptoms:
With certain configurations, virtual server keeps rejecting connections for rstcause 'VIP down' after 'trigger' events.

Conditions:
Required Configuration:

-- On the virtual server, the service-down-immediate-action is set to 'reset' or 'drop'.

-- The pool member has rate-limit enabled.

Required Conditions:

-- Monitor flap, or adding/removing monitor or configuration change made with service-down-immediate-action.

-- At that time, one of the above events occur, the pool member's rate-limit is active.

940837-4 : The iRule command node is not triggered in CLIENT_ACCEPTED with HTTP/2.

Links to More Info: BT940837

Component: Local Traffic Manager

Symptoms:
The node iRule command causes the specified server node to be used directly, thus bypassing any load-balancing. However, with HTTP/2, the node command may fail to execute within the CLIENT_ACCEPTED event. This results in no traffic being sent to configured node.

Conditions:
-- A node command is used under CLIENT_ACCEPTED event.
-- An HTTP/2 profile applied to virtual server.
-- The HTTP/2 protocol in use.

Impact:
With HTTP/2 configured, the iRule node command fails to execute within the CLIENT_ACCEPTED event, causing no traffic to be sent to the desired node.

Workaround:
As a workaround, you may use HTTP_REQUEST event instead of CLIENT_ACCEPTED in iRule syntax.

937649-4 : Flow fwd broken with statemirror.verify enabled and source-port preserve strict

Links to More Info: BT937649

Component: Local Traffic Manager

Symptoms:
Flow forwarding does not work with statemirror.verify enabled and source-port is preserve strict. Depending on the number of tmms and the IP addresses/ports on the network, this causes return traffic to get dropped.

Traffic captures show packets leaving the BIG-IP system on one tmm and being returned on another. The return traffic that encounters the second tmm is dropped.

Conditions:
-- Mirroring is enabled.
-- High availability (HA) peer is connected.
-- The source-port setting is preserve-strict.
-- The statemirror.verify option is enabled.
-- There is more than one tmm.

Impact:
Server-side return traffic to the BIG-IP is dropped. This causes connection timeouts and resets.

Workaround:
-- Disable statemirror.verify, disable source-port preserve-strict, disable mirroring.

-- On BIG-IP Virtual Edition (VE), add the following to tmm_init.tcl on both units and restart tmm:
 ndal ignore_hw_dag yes


937573-1 : Connections drop in virtual server with Immediate Action On Service Down set to Drop

Links to More Info: BT937573

Component: Local Traffic Manager

Symptoms:
In a virtual server configured with Immediate Action On Service Down set to Drop and an iRule to pick a pool different from the one attached to the virtual server, if the default pool is attached in an offline state, connections are always dropped even when the default pool becomes available later.

Conditions:
- Virtual server configured with Immediate Action On Service Down set to Drop.
- An iRule selects a different pool from the one attached to the virtual server.

Impact:
Connections are silently dropped.

Workaround:
Change the virtual server's Immediate Action On Service Down setting to None.

937481-5 : Tomcat restarts with error java.lang.OutOfMemoryError

Links to More Info: BT937481

Component: TMOS

Symptoms:
In the GUI, while trying to list a large configuration, tomcat restarts with error java.lang.OutOfMemoryError: Java heap space due to a large read operation.

Conditions:
-- From the GUI, navigate to Local Traffic :: Pools :: Pool List.
-- The configuration contains approximately 10,000 objects (objects include pools, nodes, virtual servers, etc.).

Impact:
When the system attempts to list the large configuration, tomcat restarts, resulting in 503 error.

Workaround:
Use the provision.tomcat.extramb database variable to increase the maximum amount of Java virtual memory available to the tomcat process.

Impact of workaround: Allocating additional memory to Apache Tomcat may impact the performance and stability of the BIG-IP system. You should perform this procedure only when directed by F5 Technical Support after considering the impact to Linux host memory resources.

-- Using a utility such as free or top, determine if you have enough free memory available to use this procedure.

For example, the following output from the free utility shows 686844 kilobytes available:
total used free shared buffers cachedMem:
16472868 15786024 686844 807340 827748 2543836
-/+ buffers/cache: 12414440 4058428
Swap: 1023996 0 1023996

-- View the current amount of memory allocated to the tomcat process by typing one of the following commands:
ps | grep " -client" | egrep -o Xmx'[0-9]{1,5}m'

The command output appears similar to the following example:

Xmx260m
Xmx260m

-- View the current value of the provision.tomcat.extramb database variable by typing the following command
tmsh list /sys db provision.tomcat.extramb

-- Set the provision.tomcat.extramb database variable to the desired amount of additional memory to be allocated using the following command syntax:
modify /sys db provision.tomcat.extramb value <MB>

-- If the device is part of a high availability (HA) configuration, the provision.tomcat.extramb database value should be synchronized to the peer devices from the command line. To run the ConfigSync process, use the following command syntax:
tmsh run /cm config-sync <sync_direction> <sync_group>

For example, the following command pushes the local device's configuration to remote devices in the Syncfailover device group:

tmsh run /cm config-sync to-group Syncfailover

-- Restart the tomcat process by typing the following command:
restart /sys service tomcat

936361-2 : IPv6-based bind (named) views do not work

Links to More Info: BT936361

Component: Global Traffic Manager (DNS)

Symptoms:
Bind does not match IPv6 addresses configured for a zone view, and returns REFUSED responses, rather than the
expected answers.

After enabling debug logging in bind (see K14680), the apparent source address of the IPv6 DNS requests shows as being in the fe80::/96 range, rather than the IPv6 source address that sent the request.

For example:

debug 1: client @0x579bf188 fe80::201:23ff:fe45:6701%10#4299: no matching view in class 'IN'

Conditions:
- BIG-IP DNS is provsioned
- One or more ZoneRunner views is defined using IPv6 addresses.
- A DNS query is sent from an IPv6 source address

Impact:
You cannot use DNS views in bind (zonerunner) based on IPv6 addresses.

Workaround:
If possible, use only IPv4 addresses to define views for DNS queries


936093-5 : Non-empty fipserr files loaded from a UCS archive can cause a FIPS BIG-IP platform to remain offline

Links to More Info: BT936093

Component: TMOS

Symptoms:
Loading a UCS file with non-empty fipserr files can cause a FIPS-based system to remain offline.

Conditions:
-- Using a BIG-IP with a Platform FIPS license.
-- Loading a UCS file with a non-empty fipserr file.

Impact:
System is completely offline with spurious 'fipserr' failures, even after loading the UCS file.

933777-5 : Context use and syntax changes clarification

Links to More Info: BT933777

Component: Application Visibility and Reporting

Symptoms:
There are two context and syntax-related issues:

-- In v14.x, the context for tmsh analytics commands related to server side connections changed. For example, 'total-server-side-conns' became a simple 'server-side-conns'.

-- In v13.x and 14.x, the calculation method for 'max-tps' changed from cumulative to commutative.

Conditions:
This occurs in either of the following scenarios:
-- Using tmsh analytics commands related to max-tps in v13.x or later.
-- Using tmsh analytics commands related to server side connections in BIG-IP v14.x and later.

Impact:

932857-5 : Delays marking Nodes or Pool Members DOWN with in-TMM monitoring

Links to More Info: BT932857

Component: In-tmm monitors

Symptoms:
When configured with a large number of in-TMM monitors, Nodes or Pool Members may not be marked DOWN immediately after the configured timeout period once the target stops responding to pings.

Conditions:
This may occur when:
-- In-TMM monitoring is enabled (via sys db bigd.tmm).
-- A large number of Nodes and/or Pool Members (several hundreds or thousands) are configured and monitored.

Impact:
Nodes or Pool Members which are not responsive may not be marked DOWN in a timely fashion.

Workaround:
You can work around this issue by disabling in-TMM monitoring, at the expense of decreased monitoring performance (higher CPU usage by the bigd daemon).

931149-3 : Some RESOLV::lookup queries, including PTR lookups for RFC1918 addresses, return empty strings

Links to More Info: BT931149

Component: Global Traffic Manager (DNS)

Symptoms:
RESOLV::lookup returns an empty string.

Conditions:
The name being looked up falls into one of these categories:

-- Forward DNS lookups in these zones:
    - localhost
    - onion
    - test
    - invalid

-- Reverse DNS lookups for:
    - 127.0.0.0/8
    - ::1
    - 10.0.0.0/8
    - 172.16.0.0/12
    - 192.168.0.0/16
    - 0.0.0.0/8
    - 169.254.0.0/16
    - 192.0.2.0/24

    - fd00::/8
    - fe80::/10
    - 2001:db8::/32
    - ::/64

Impact:
RESOLV::lookup fails.

Workaround:
Use a DNS Resolver ('net dns') and RESOLVER::name_lookup / DNSMSG:: instead of RESOLV::lookup:

1. Configure a local 'net dns' resolver, replacing '192.88.99.1' with the IP address of your DNS resolver:

    tmsh create net dns-resolver resolver-for-irules answer-default-zones no forward-zones add { . { nameservers add { 192.88.99.1:53 } } }

2. Use an iRule procedure similar to this to perform PTR lookups for IPv4 addresses:

proc resolv_ptr_v4 { addr_v4 } {
    # Convert $addr_v4 into its constituent bytes
    set ret [scan $addr_v4 {%d.%d.%d.%d} a b c d]
    if { $ret != 4 } {
        return
    }

    # Perform a PTR lookup on the IP address $addr_v4, and return the first answer
    set ret [RESOLVER::name_lookup "/Common/resolver-for-irules" "$d.$c.$b.$a.in-addr.arpa" PTR]
    set ret [lindex [DNSMSG::section $ret answer] 0]
    if { $ret eq "" } {
        # log local0.warn "DNS PTR lookup for $addr_v4 failed."
        return
    }

    # Last element in '1.1.1.10.in-addr.arpa. 600 IN PTR otters.example.com'
    return [lindex $ret end]
}

-- In an iRule, instead of:
    RESOLV::lookup @192.88.9.1 $ipv4_addr
Use:
    call resolv_ptr_v4 $ipv4_addr

928353-4 : Error logged installing Engineering Hotfix: Argument isn't numeric&start;

Links to More Info: BT928353

Component: TMOS

Symptoms:
When installing an Engineering Hotfix, the following error may be logged in /var/log/liveinstall.log:

Argument "" isn't numeric in numeric eq (==) at /var/tmp/install/pkgcpio/usr/local/lib/tm_install/Hotfix.pm line 651.

Conditions:
This error may occur when installing an Engineering Hotfix, if the Engineering Hotfix does not include an update to the nash-initrd component.

Impact:
The error message gives a mistaken impression that the Engineering Hotfix did not install successfully. However, it does install correctly, and the system operates without issue. You can safely ignore this message.

928161-3 : Local password policy not enforced when auth source is set to a remote type.

Links to More Info: BT928161

Component: TMOS

Symptoms:
The local password policy is not enforced when the auth source type is set to the value of 'Remote'. Any non-default password policy changes are not enforced for local users.

Conditions:
1) Some parts of the local password policy has been changed from the default values, for example, changing the password required-uppercase to 2.

2) The auth source is set to a remote source, such as LDAP, AD, or TACACS.

Impact:
The system does not enforce any of the non-default local password policy options.

For example, even if the required-uppercase is set to 2, a local user's password can be set to something less than 2.

Even if the minimum-length is set to 12, a local user's password can be set to something less than 12.

Another example, even if the max-duration is set to 90 days, the password does not expire for 99999 days (the default).

Workaround:
None

927025-1 : Sod restarts continuously

Links to More Info: BT927025

Component: TMOS

Symptoms:
After upgrading to v14.1.2.6, sod keeps restarting and dumping core.

Conditions:
This occurs when /dev/shm/chmand is missing and the system restarts chmand and sod upon reload.

Note: It is unknown how this condition might occur.

Impact:
Unstable sod process can affect failover functionality in BIG-IP systems.

Note: This happens only the first time after upgrade. To recover, you must power down the system for a full reboot.

Workaround:
Run the following command:

restorecon /dev/shm/chmand


926549-3 : AFM rule loops when 'Send to Virtual' is used with Virtual Server iRule 'LB::reselect'

Links to More Info: BT926549

Component: Advanced Firewall Manager

Symptoms:
With some configurations, executing a command such as 'tmsh show security firewall global-rules active' loops continuously, causing stat counters to rise, and possibly log messages to be written to /var/log/ltm.

Conditions:
-- AFM is routing traffic to a Virtual Server through the 'Send to Virtual' option.
-- The target Virtual Server uses the 'LB_FAILED' iRule to select a new Virtual Server through virtual command and 'LB::reselect'.

Impact:
The iRule loops continuously, causing stat counters to rise, and possibly logging messages in /var/log/ltm.

Workaround:
This configuration should be avoided, but if it is used, and if this does happen, you can restart tmm:
bigstart restart tmm

This stops the current looping, until it is triggered again.

Impact of workaround: Traffic disrupted while tmm restarts.


926425-4 : Hardware SYN Cookies may not deactivate after the SYN attack ends and valid TCP traffic starts

Links to More Info: BT926425

Component: Advanced Firewall Manager

Symptoms:
Hardware SYN Cookies activated on a virtual server under a SYN attack may not deactivate after the SYN attack ends and valid TCP traffic starts. The non-supported TCP options under SYN Cookie protection continue to be unsupported until hardware SYN cookies are disabled.

Conditions:
SYN Cookie activated on Neuron-capable platforms:
  + VIPRION B4450N blade
  + BIG-IP iSeries devices (ix800) except the i850, ix2800, and ix4800:
     -- BIG-IP i5800 Series
     -- BIG-IP i7800 Series
     -- BIG-IP i11800 Series
     -- BIG-IP i15800 Series

Impact:
This can successfully cause hardware SYN cookies to be activated on the BIG-IP virtual server under attack. However, once the attack subsides and falls below the SYN check threshold, SYN cookies may not immediately deactivate.

Because SYN cookie protection is still active, and because under SYN cookie protection some TCP options are not supported, the options are not taken into account when processing traffic. For example, under SYN cookie protection, MSS is fixed to a few sizes. For traffic that arrives with a different MSS size, the system uses a supported size instead.

Workaround:
You can use any of the following to clear the HSB issue:
-- Restart neurond.
-- Restart TMM,
-- Reboot the device.


926341-5 : RtIntervalSecs parameter in /etc/avr/avrd.cfg file is reset on version upgrade&start;

Links to More Info: BT926341

Component: Application Visibility and Reporting

Symptoms:
Unusually high AVR CPU utilization occurs following an upgrade.

Conditions:
-- BIG-IP software upgrade to v13.0.x or later.
-- Running AVR.

Impact:
AVR CPU utilization can be unusually high for an unusually long period of time.

Workaround:
After upgrade manually edit /etc/avr/avrd.cfg to decrease AVR CPU usage is high by increasing the time period of real-time statistics collection. In order to do so:
1. Change value of RtIntervalSecs in /etc/avr/avrd.cfg file to 30 or 60 seconds.
2. Restart the system by running the following command at the command prompt:
bigstart restart.

When changing RtIntervalSecs please take into consideration two important limitations:
-- Value of RtIntervalSecs cannot be less than 10.
-- Value of RtIntervalSecs must be 10 on BIG-IP devices that are registered on BIG-IQ DCD nodes.


926085-2 : GUI: Node/port monitor test not possible in the GUI, but works in tmsh

Links to More Info: BT926085

Component: Local Traffic Manager

Symptoms:
The node address field is disabled when trying to create a custom HTTP/HTTPS/FTP monitor, so you cannot enter a node address. This prevents you from using the Test operation to test this type of monitor in the GUI.

Conditions:
-- In a new monitor derived from HTTP/HTTPS/FTP, click the Test tab.
-- View the Address field, and then try to run the test.

Impact:
The Address field is disabled, with *.* in the field. You cannot enter a node address. The test fails with a message:

invalid monitor destination of *.*:80.
invalid monitor destination of *.*:443. (:port used to test)

Workaround:
Run either of the following tmsh commands:

for HTTP
-- tmsh run ltm monitor http my_http destination <IP address>:<port>

-- tmsh modify ltm monitor http my_http destination *:*

for HTTPS
-- tmsh run ltm monitor https my_https destination <IP address>:<port>

-- tmsh modify ltm monitor https my_https destination *:*


925469-2 : SubjAltName (SAN) cannot be sent in the Certificate Order Manager for Comodo / Sectigo

Links to More Info: BT925469

Component: TMOS

Symptoms:
When using the Certificate Order Manager to request new Multi-Domain certificate from the Sectigo Certificate Authority (CA), the request the BIG-IP sends is missing the field 'subjectAltName'.

Conditions:
-- Certificate Order Manager is configured to send requests to the Comodo/Sectigo CA.

-- Configure a new key with Subject Alternative Name (SAN).

Impact:
The BIG-IP system sends a request to the Sectigo CA that is missing the 'subjectAltName' field. That makes Certificate Order Manager not suitable for requesting Multi-Domain certificates.

Workaround:
There is no workaround other than not using Certificate Order Manager for Multi-Domain certificates.


924589-3 : PEM ephemeral listeners with source-address-translation may not count subscriber data

Links to More Info: BT924589

Component: Policy Enforcement Manager

Symptoms:
When a PEM profile is associated with a protocol that can create dynamic server-side listeners (such as FTP), and source-address-translation is also enabled on the virtual server, traffic on that flow (for example ftp-data) is not associated with the subscriber, and is therefore not counted or categorized.

Conditions:
-- Listener configured with PEM and FTP profiles
-- Some form of source address translation is enabled on the listener (for example, SNAT, Automap, SNAT Pool)

Impact:
Inaccurate subscriber traffic reporting and classification.

Workaround:
None.


924297-4 : Ltm policy MCP objects are not being synced over to the peer device

Links to More Info: BT924297

Conditions:
-- Sync/failover device group with full load on sync disabled
-- A draft policy is attached to a parent policy's rule actions and published.
-- A config sync occurs (manually or automatically)

Impact:
The LTM policy does not sync to the peer device.

Workaround:
Perform a full config sync:

tmsh run cm config-sync force-full-load-push to-group <device group name>

Impact:
Traffic disrupted while tmm restarts.


922641-6 : Any iRules that park in a clientside or serverside command leave the iRule attached to the wrong flow

Links to More Info: BT922641

Component: Local Traffic Manager

Symptoms:
iRule commands issued after a clientside or serverside command operate on the wrong peer flow.

Conditions:
An iRule contains a script that parks in a clientside or serverside command.

Examples of parking commands include 'table' and 'persist'.

Impact:
The iRule commands operate on the wrong peer flow.

Workaround:
Avoid using commands that park inside the clientside or serverside command.


922613-6 : Tunnels using autolasthop might drop traffic with ICMP route unreachable

Links to More Info: BT922613

Component: TMOS

Symptoms:
Traffic that should be encapsulated and sent via tunnel might get dropped with an ICMP error, destination unreachable, unreachable route. This happens in a scenario where no route exists towards the remote tunnel endpoint and the BIG-IP system relies on autolasthop to send the encapsulated traffic back to the other end of the tunnel.

Conditions:
No route exists to the other end of the tunnel.

Impact:
Traffic dropped with ICMP error, destination unreachable, unreachable route.

Workaround:
Create a route towards the other remote end of the tunnel.


922413-8 : Excessive memory consumption with ntlmconnpool configured

Links to More Info: BT922413

Component: Local Traffic Manager

Symptoms:
OneConnect allows load balancing of HTTP requests from the same client connection over a pool of server side connections. When NTLM authentication is used, the NTLM Conn Pool allows reuse of server-side connections for authenticated client side connections. It holds HTTP authentication headers which is no longer necessary once a client is authenticated.

Conditions:
-- The virtual server is configured with both OneConnect and NTLM Conn Pool profiles.
-- A large number of client systems with NTLM authentication are load balanced via the virtual server with long-lived connections.

Impact:
The BIG-IP system experiences memory pressure, which may result in an out-of-memory condition and a process crash, and potentially cause failover and interruption of traffic processing.

Workaround:
None.


922153-5 : Tcpdump is failing on tmm 0.x interfaces

Links to More Info: BT922153

tcpdump: pcap_loop: TMM side closing: Aborted

Conditions:
Capturing the packets on tmm interfaces.

Impact:
Unable to capture the packets on specific tmm interfaces.

Workaround:
There are two possible workarounds:

-- Start tcpdump on the tmm that actually owns the interface using the TCPDUMP_ADDR command; for example, using blade1 for 1/0.16, run the command:

TCPDUMP_ADDR=127.1.1.16 tcpdump -w testcap.pcap -s 0 -i 1/0.16


-- Send the TCPDUMP_ADDR command to a specific tmm, which could work from any blade (127.20.<slot>.<tmmnumber+1> (e.g. 127.20.1.1 == slot1/tmm0, 127.20.2.16 == slot2/tmm15):

TCPDUMP_ADDR=127.20.1.16 tcpdump -w testcap.pcap -s 0 -i 1/0.16

921441-4 : MR_INGRESS iRules that change diameter messages corrupt diam_msg

Links to More Info: BT921441

Component: Service Provider

Symptoms:
-- 'DIAMETER::host origin' command may not be set correctly.

There are errors in ltm/log:
err tmm[18562]: 014c0001:3: DIAMETER: hud_diam_handle error: Not found

Conditions:
-- Virtual server is configured with a diameter profile enabled with an ingress iRule, for example:

ltm rule Diameter - iRule {
  when MR_INGRESS {
    DIAMETER:: host origin "hostname.realm.example"
  }
}

-- Traffic arrives containing CER and ULR messages.

Impact:
Using the iRule to change the host origin corrupts the diameter message.

Workaround:
None.


920817-7 : Wide IP operations performed in quick succession result in missing resource records and out of sync journals.

Links to More Info: BT920817

Component: Global Traffic Manager (DNS)

Symptoms:
Two issues occur with Wide IP operations performed in quick succession:
1. DNS Zone syncing is missing resource records.
2. In some cases it throws named/zrd error: journal rollforward failed: journal out of sync with zone.

Conditions:
This issue can occur when a large number of configuration changes, including Wide IP changes, are made simultaneously on multiple GTM/DNS devices in a sync group.

Impact:
DNS resource records can be missing from the BIND DNS database.

The impact of this issue is that if GSLB Load Balancing falls back to BIND, the DNS resource records may not be present.
Manually remove the .jnl files in order to restore named/zrd on all GTMs.

Workaround:
Restrict configuration (Wide IP) changes to one GTM/DNS device in a device group.

Note: It is also possible to turn off zone syncing. GTM/DNS configuration is still synced, but you lose the ability to sync non-Wide IP changes to the BIND DB.
If you do not use ZoneRunner to add additional non-Wide IP records, this is only a problem when GSLB resorts fallback to BIND.
This can be mitigated with DNSX and DNS (off device) for non Wide IP Resource Records.

Manually remove the .jnl files in order to restore named/zrd on all GTMs.

A duplicate value was received for a non-primary key unique index field. DB exception text (Cannot update_indexes/checkpoint DB object, class:gtm_wideip_alias status:13)
Unexpected Error: Loading configuration process failed.

Conditions:
-- A wideip alias is moved from one wideip to another
-- GTM sync occurs, or a gtm config is loaded manually.

This issue can occur any time a GTM config is loaded or synchronised where the new configuration has a wideip with an alias, which is already configured on a different wideip in the existing in-memory GTM configuration.

Impact:
You are unable to load config or full sync from peer GNS/GTM.

Workaround:
Follow this procedure:
1. Delete the wide IP alias on the destination device.
2. Try the sync or load config operation again.

When the IKEv1 racoon daemon starts, it may immediately exit with a core file.

Conditions:
One of the following events may lead to the restart:
-- BIG-IP systems start or restart as a standalone device.
-- BIG-IP becomes the Active member of High Availability (HA) setup.

Impact:
Racoon restarts. Because this restart happens when racoon is trying to start, no IPsec IKEv1 tunnels are affected because they are down anyway.

Workaround:
None

Do not set log.gtm.level equal to or higher than debug.


910777-1 : Sending ASM report via AWS SES failed duo to wrong content type

Links to More Info: BT910777

Component: Application Visibility and Reporting

Symptoms:
When you attempt to send an ASM report via AWS SES, the message bounces with the following message:
  Could not send e-mails: SMTP Error: data not accepted.; Transaction failed: Expected MIME type, got ;; Error code: 554.

This occurs because the BIG-IP system is sending out the report message with an empty Content-Type in the multipart MIME, which the AWS mail host cannot process.

Conditions:
This is encountered in the following scenario:
1. Set up SMTP and ASM schedule report.
2. Click Send Now, and get the error message in GUI.
3. SSH into the BIG-IP system.
4. Add this line under the following snippet:

[admin@bigip:Active:Standalone] ~ # chmod 644 /var/ts/dms/script/avrexport/avrmail.php
[admin@bigip:Active:Standalone] ~ # vi /var/ts/dms/script/avrexport/avrmail.php

if (!$mail_subject) $mail_subject = "BIG-IP Analytics Report";
if (!$mail_body) $mail_body = "Attached to this e-mail is a BIG-IP Analytics Report issued at $mail_time\n\n";
if (!$mail_from) $mail_from = 'BIG-IP Reporter';
if (!$mail_content_type) $mail_content_type = 'text/html'; <<<< Add this line for add text/html into content type.

[admin@bigip:Active:Standalone] ~ # chmod 444 /var/ts/dms/script/avrexport/avrmail.php

5. Click Send Now again and it works.


Note: To use AWS SES, you must verify your email address first (as a Sender). You can search SES in AWS and verify your email in Email Addresses. AWS sends an email. Click the embedded link after receipt, and then you can use it as the Sender address on the BIG-IP system.

Impact:
Cannot receive ASM reports.

Conditions:
-- Password memory in auth settings is not 0 (zero).
-- Attempt to specify a previously specified password

Impact:
Password history to prevent user from using same password is not enforced.

Workaround:
None.


908453-5 : Trunks with names longer than 32 characters update working-mbr-count in vCMP guests incorrectly

Links to More Info: BT908453

Component: TMOS

Symptoms:
When a trunk is configured with a name longer than 32 characters on a vCMP host, guests update the working-mbr-count for the trunk incorrectly when another trunk on the host changes. This might result in vCMP guests failing over unexpectedly.

Conditions:
-- Trunk configured with a name longer than 32 characters on vCMP host.
-- Trunk made available to guests for high availability (HA) Group scoring.
-- At least one other trunk configured on vCMP host.
-- Interface state changes in any other trunk.

Impact:
The vCMP guests may fail over unexpectedly.

Workaround:
Do not use trunk names longer than 32 characters.


908001-2 : vCMP guest CPU usage may increase 4-5% after upgrade of vCMP host to v16.1.x&start;

Links to More Info: BT908001

Component: Performance

Symptoms:
All vCMP guest configurations might see a 4-5% increase in CPU usage while running on VIPRION and iSeries platforms with the vCMP host upgraded to v16.1.x

Conditions:
-- All configurations (guest software version is not relevant)
-- Running vCMP on VIPRION and iSeries platforms
-- 'Host' upgraded to v16.1.x

Impact:
Increase of CPU usage of about 4-5% on the vCMP guest. This is not expected to cause noticeable performance impacts unless the vCMP guest CPU is already close to 100% use, when it is possible there may be up to a 15% TPS decrease.
 
If you are running vCMP on VIPRION and iSeries platforms, first evaluate your scenarios and capacity plan if you plan to upgrade the 'host' to 16.1.x.

Note: There is no CPU usage increase when v16.1.x 'guest' instances are run on an earlier 'host' version.

Guidance: In determining whether to upgrade the vCMP host to v16.1.x, carefully evaluate the performance and sizing requirements of your specific configuration.

Workaround:
None


907177-5 : Priority of embedded APM iRules is ignored

Links to More Info: BT907177

Component: Local Traffic Manager

Symptoms:
Custom iRule events are executed before the embedded APM iRule events, despite the custom iRule's priority value being larger than the APM iRule's priority value.

Conditions:
-- APM is provisioned.
-- Custom iRule with a priority value larger the APM iRule's priority value.

Impact:
Custom iRule event is executed before APM iRule event.

Workaround:

906653-1 : Server side UDP immediate idle-timeout drops datagrams

Links to More Info: BT906653

Component: Local Traffic Manager

Symptoms:
With immediate idle-timeout, flows may be closed before a datagram is forwarded.

Conditions:
-- Immediate idle-timeout is set on the server context of a UDP virtual server.

Impact:
Datagrams are dropped periodically depending on traffic load.

Workaround:
None.


905477-6 : The sdmd daemon cores during config sync when multiple devices configured for iRules LX

Links to More Info: BT905477

Component: Local Traffic Manager

Symptoms:
The iRules LX workspaces belong on only one device in a Device Service Cluster (DSC). If you have the same iRules LX workspace configured on multiple devices and then perform a config sync operation, the sdmd daemon cores.

Conditions:
-- Multiple devices configured with the same iRules LX workspace in a DSC.
-- Change one of the devices such that the configuration requires a config sync.
-- Perform the config sync.

Impact:
The sdmd daemon cores. Although having multiple devices configured with the same iRules LX workspace is an incorrect configuration, sdmd should not core.

Workaround:
When the iRules LX workspace is correctly configured, i.e., on only one device in a DSC, there is no need to config sync, so this issues does not occur.


904713-2 : FailoverState device status and CM device status do not match shortly after triggering failover

Links to More Info: BT904713

Component: TMOS

Symptoms:
After triggering failover, the result returned by the API endpoint /mgmt/tm/shared/bigip-failover-state (the BIG-IP failover state worker) may not match the actual device failover state.

Conditions:
This may happen on an high availability (HA) setup with a sync-failover device group.

Impact:
Actions that require the correct output of the BIG-IP failover state worker may fail. For instance, deleting an SSL Orchestrator topology followed by immediately triggering failover may encounter this issue, causing the deletion to fail.

Workaround:
After waiting for a short amount of time, the BIG-IP failover state worker gets in sync with the device failover state. So in the example of deleting an SSL Orchestrator topology, the deletion should be successful if you try again after a short wait.


904537-1 : The csyncd process may keep trying to sync the GeoIP database to a secondary blade

Links to More Info: BT904537

Component: Local Traffic Manager

Symptoms:
The most common symptom is when csyncd repeatedly syncs the GeoIP files and loads the GeoIP database, causing a large number of Clock advanced messages on all tmms.

Repeated log messages similar to the following are reported when a secondary slot logs into the primary slot to load the sys geoip database:

-- info sshd(pam_audit)[17373]: 01070417:6: AUDIT - user root - RAW: sshd(pam_audit): user=root(root) partition=[All] level=Administrator tty=ssh host=x.x.x.x attempts=1 start="Wed Apr 29 13:50:49 2020".
-- notice tmsh[17401]: 01420002:5: AUDIT - pid=17401 user=root folder=/Common module=(tmos)# status=[Command OK] cmd_data=load sys geoip.

Conditions:
-- VIPRION or vCMP guests.
-- Either of the following:
   - First installing the GeoIP database if the /shared/GeoIP/v2 directory does not exist.
   - When a new blade is installed into a chassis.

Impact:
Repeated logs of Clock advanced messages.

Workaround:
Run the command:
 clsh bigstart restart csyncd


904401-5 : Guestagentd core

Links to More Info: BT904401

Component: TMOS

Workaround:
Remove 'dnssec-enable no' from named.conf in options section.


903501-3 : VPN Tunnel establishment fails with some ipv6 address

Links to More Info: BT903501

Component: Access Policy Manager

Symptoms:
VPN Tunnel establishment fails with some ipv6 address

Conditions:
- APM is provisioned.
- Network Access with IPv6 virtual server is configured.

Impact:
VPN Tunnel cannot be established.

Workaround:
1. Disable the DB variable isession.ctrl.apm:
tmsh modify sys db isession.ctrl.apm value disable

2. Perform 'Apply Access Policy' for the access policy attached to the virtual server.

Important: The iSession control channel is needed if optimized apps are configured, so use this workaround only when 'No optimized apps are configured' is set (available in the GUI by navigating to Access :: Connectivity / VPN : Network Access (VPN) : Network Access Lists :: {NA resources} :: 'Optimization' tab).


903313-4 : OWASP page: File Types score in Broken Access Control category is always 0.

Links to More Info: BT903313

Component: Application Security Manager

Symptoms:
Under Broken Access Control category, the contribution of Disallowed File Types seems to be 0 no matter what is the number of Disallowed File Types in policy. As a result, it is not possible to reach full compliance.

Conditions:
Security Policy is configured. Not Applicable for parent or child policy.

Impact:
For any OWASP configurable policy (i.e. not parent or child policy), the policy cannot reach the maximum score for Broken Access Control category


901569-4 : Loopback traffic might get dropped when VLAN filter is enabled for a virtual server.

Links to More Info: BT901569

Component: Local Traffic Manager

Symptoms:
Loopback traffic (local traffic) destined to a virtual server might get dropped when the incoming packet matches a terminating connection flow.

Conditions:
-- VLAN filter is enabled on the virtual server created for loopback traffic processing.
-- An incoming packet matches a terminating connection flow (i.e., the connection flow terminates because of timeout, being dropped by iRule, etc.).

Impact:
Traffic that is matched against a terminating connection flow of a virtual is not processed by the virtual server.

Workaround:
Because this filter is ignored for loopback traffic, removing the 'Enabled On VLAN' filter at the virtual server mitigates the issue.


899253-1 : [GUI] GTM wideip-pool-manage in GUI fails when tens of thousands of pools exist

Links to More Info: BT899253

Component: Global Traffic Manager (DNS)

Symptoms:
Making changes to wide IP pools through GUI management do not take effect.

Conditions:
-- GTM configuration contains a sufficiently high number of pools (~ 15,000).
-- Using the GUI to assign a pool to a wide IP.

Impact:
Changes do not take effect. Unable to use the GUI to manage which pools are associated with a wide IP.

Workaround:
Use TMSH.


898381-3 : Changing the setting of apm-forwarding-fastl4 profile does not take effect

Links to More Info: BT898381

Component: Access Policy Manager

Symptoms:
Changing the setting of apm-forwarding-fastl4 profile does not take effect and is not getting applied to the last leg of client-initiated VPN traffic.

Conditions:
- APM is configured on the BIG-IP system.
- BIG-IP Administrator (Admin) has configured a VPN tunnel.
- Admin is trying to change the TCP characteristic of the last leg of VPN tunnel traffic by tuning the parameters of FastL4 profile apm-forwarding-fastl4.

Impact:
Admin cannot enforce the updated values of apm-forwarding-fastl4 profile on the last leg of client-imitated VPN tunnel traffic.

Workaround:
None.


897437-7 : First retransmission might happen after syn-rto-base instead of minimum-rto.

Links to More Info: BT897437

Component: Local Traffic Manager

Symptoms:
If a TCP profile is configured with a syn-rto-base value that is lower than minimum-rto, the first retransmission might happen after syn-rto-base.

This behavior is encountered only if the BIG-IP system is unable to compute the new RTO value before the retransmission timer expires, meaning:

-- The BIG-IP system has not received a packet with a TCP timestamp reply.
-- The BIG-IP system has not received an ACK for a timed sequence number.

Conditions:
Configured value of syn-rto-base is lower than minimum-rto.

Impact:
Retransmission might happen sooner than expected.

Workaround:
There are two possible workarounds:

-- Avoid using a syn-rto-base value that is lower than the minimum-rto value (the default values are 3 seconds for syn-rto-base and 1 second for minimum-rto).

-- Consider enabling timestamps to allow faster RTT measurement.


894593-2 : High CPU usage caused by the restjavad daemon continually crashing and restarting

Links to More Info: BT894593

Component: TMOS

Symptoms:
Restjavad may become unstable if the amount of memory required by the daemon exceeds the value allocated for its use.

Conditions:
The memory required by the restjavad daemon may grow significantly in system configurations with either a high volume of device statistics collection (AVR provisioning), or a with relatively large number of LTM objects managed by the REST framework (SSL Orchestrator provisioning).

Impact:
The overall system performance is degraded during the continuous restart of the restjavad daemon due to a relatively high CPU usage.

Workaround:
Increase the memory allocated for the restjavad daemon (e.g., 2 GB), by running the following commands in a BIG-IP terminal.
 
tmsh modify sys db restjavad.useextramb value true
tmsh modify sys db provision.extramb value 2048
bigstart restart restjavad

Note this may lead to impact on multi-module systems with ASM as approximately only 50-60% of provision.extramb value would be allocated as extra host memory and restjavad may take up to 80% of provision.extramb. It also lowers the ASM specific host allocation resulting in some tighter memory contraints on ASM daemons. Try to use the smallest value that works.


891145-7 : TCP PAWS: send an ACK for half-open connections that receive a SYN with an older TSVal

Links to More Info: BT891145

Component: Local Traffic Manager

Symptoms:
SYNs received with TSVal <= TS.Recent are dropped without sending an ACK in FIN-WAIT-2 state.

Conditions:
-- Timestamps are enabled in TCP profile.
-- Local TCP connection is in FIN-WAIT-2 state.
-- Remote TCP connection abandoned the flow.
-- A new TCP connection sends a SYN with TSVal <= TS.Recent to the local connection.

Impact:
The new TCP connection cannot infer the half-open state of Local TCP connections, which prevents faster recovery of half-open connections. The local TCP connection stays around for a longer time.

Workaround:
There are two workarounds:

-- Reduce the Fin Wait 2 timeout (the default: 300 sec) so that TCP connection is terminated sooner.

-- Disable TCP Timestamps.


890169-4 : URLs starting with double slashes might not be loaded when using a Bot Defense Profile.

Links to More Info: BT890169

Component: Application Security Manager

Symptoms:
When a URL starts with double slashes (i.e. "http://HOST//path"), and Bot Defense Profile decides to perform simple redirect, the request results with loading failure.

Conditions:
-- Bot Defense profile on blocking mode (or "Verification and Device-ID Challenges in Transparent Mode" is enabled) is attached to a virtual server.
-- A request is sent to a URL starting with double slash, to a non-qualified URL, during the profile's grace period.

Impact:
Request is not loaded (failure message is seen on browser), and the browser may be identified as a suspicious browser by Bot Defense.

Workaround:

Nslookup generates a core file. The core file name might start with "nslookup", "isc-worker", "isc-timer" or "isc-socket".

Conditions:
Multiple instances of nslookup are running when the system shuts down.

Impact:
A core file is generated. However, since this is during system shutdown, the impact should be minimal.


882729-5 : Applied Blocking Masks discrepancy between local/remote event log

Links to More Info: BT882729

Component: Application Security Manager

Symptoms:
Applied Blocking Masks discrepancy between local/remote event log, ASM logging event logs both locally and remotely to BIG-IQ has discrepancy.

Conditions:
This occurs when "Applied Blocking Masks" logs are emitted on a device where local and remove event logging is configured.

Impact:
This is cosmetic but can lead to confusion.


881937-2 : TMM and the kernel choose different VLANs as source IPs when using IPv6.

Links to More Info: BT881937

Component: Local Traffic Manager

Symptoms:
IPv6 traffic generated from the host, either from a host daemon, monitors, or from the command line, can use a MAC and IPv6 source address from different VLANs.

Conditions:
-- Multiple VLANs configured with IPv6 addresses.
-- Multiple routes to the same destination, either the same or more specific, default routes, etc., that cover the traffic destination.
-- Changes are made to routes that cause the traffic to the destination to shift from one VLAN and gateway to another. This can be typically observed with dynamic routing updates.
- The db key snat.hosttraffic is set to disable.

Impact:
Traffic to the destination may fail because the incorrect source IPv6/MAC address is used, which might cause monitor traffic to fail.

Workaround:
tmsh list sys db snat.hosttraffic
tmsh modify sys db snat.hosttraffic value enable
tmsh save sys config


881065-5 : Adding port-list to Virtual Server changes the route domain to 0

Links to More Info: BT881065

Component: Local Traffic Manager

Symptoms:
When attaching the port-list to virtual server dest:port-list, the route domain of the virtual server is changed to the default value of 0, and the port-list is not correctly applied. This is encountered in the GUI but not in the CLI.

Conditions:
Using port-list along with virtual server in non default route domain using the GUI.

Impact:
You are unable to use the GUI to attach a port-list that uses a non-default route domain to a virtual server.

Workaround:
Use tmsh to attach a port-list to a virtual server if the port-list uses a non-default route domain.


880689-1 : Update oprofile tools for compatibility with current architecture

Links to More Info: BT880689

Component: TMOS

Symptoms:
Current operf as shipped with BIG-IP is out of date and will not work.

Per the oprofile page (https://oprofile.sourceforge.io/news/) the version included in our systems (0.9.9) was released in 2013.

Conditions:
Opcontrol still works but operf will not load.
# operf --version
use the opcontrol command instead of operf.

Impact:
Outdated operf means that it cannot be used for troubleshooting purposes.


880565-5 : Audit Log: "cmd_data=list cm device recursive" is been generated continuously

Links to More Info: BT880565

Component: Device Management

Symptoms:
The system generates and logs the following message continuously, at the rate of 3 times a minute, in /var/log/audit:

-- bigip1 notice tmsh[47755]: 01420002:5: AUDIT - pid=47755 user=root folder=/ module=(tmos)# status=[Command OK] cmd_data=cd / ;
-- bigip1 notice tmsh[47755]: 01420002:5: AUDIT - pid=47755 user=root folder=/ module=(tmos)# status=[Command OK] cmd_data=list cm

Conditions:
This occurs during normal operation.

Impact:
Audit log file contains numerous 'cmd_data=list cm device recursive' messages.

Workaround:
-- To suppress all messages, do the following:

1. Edit the 'include' section of syslog configuration to suppress audit logs of 'cmd_data=cd /' and 'cmd_data=list cm device recursive':

# tmsh edit /sys syslog all-properties

2. Replace 'include none' with following syntax:
===
sys syslog {
- snip -
    include "
filter f_audit {
       facility(local0) and match(AUDIT) and not match(\"cmd_data=list cm device recursive|cmd_data=cd /\");
};"
- snip -
}


-- To filter the messages sent to existing remote syslog servers, do the following:

1. Set sys syslog remote-servers none:
# tmsh modify sys syslog remote-servers none

2. Define the remote syslog server in the 'sys syslog include' statement.

3. Add the following filter:

   filter f_remote_server {
   not (facility(local0) and message(\"AUDIT\") and match(\"cmd_data=list cm device recursive|cmd_data=cd /\"));
    };

Result: The system sends all messages to the remote syslog server, excluding the messages that match the filter.


Here is a sample filter, with sample data:

sys syslog {
    include "
    filter f_remote_server {
    not (facility(local0) and message(\"AUDIT\") anD match(\"cmd_data=list cm device recursive|cmd_data=cd /\"));
    };
    destination d_remote_loghost {
        udp(\"10.0.0.1\" port(514));
    };
    log {
        source(s_syslog_pipe);
        filter(f_remote_server);
        destination(d_remote_loghost);
    };
    "
}


879969-8 : FQDN node resolution fails if DNS response latency >5 seconds

Links to More Info: BT879969

Component: TMOS

Symptoms:
When resolving FQDN names for FQDN nodes/pool members, pending DNS requests are timed out after 5 seconds with no response from the DNS server.
If there is a persistent latency of 5 seconds or greater in the DNS server responses, FQDN name resolution will fail and ephemeral nodes/pool members will not be created.

Conditions:
- BIG-IP using FQDN nodes/pool members
- Persistent latency of 5 seconds or greater in the DNS server responses

Impact:
Ephemeral pool members may not be created, thus no traffic will be sent to the intended pool members.

Workaround:
Resolve any persistent latency issues that might cause delays of 5 seconds or more in DNS server responses.


878641-3 : TLS1.3 certificate request message does not contain CAs

Links to More Info: BT878641

Component: Local Traffic Manager

Symptoms:

878253-5 : LB::down no longer sends an immediate monitor probe

Links to More Info: BT878253

Component: Local Traffic Manager

Symptoms:
The iRule command LB::down is supposed to send an immediate monitor probe, but it does not.

Conditions:
-- Executing LB::down in an iRule.

Impact:
A monitor probe is not immediately sent, which may cause a pool member to be marked down longer than it should be.


876569-2 : QAT compression codec produces gzip stream with CRC error

Links to More Info: BT876569

Component: Local Traffic Manager

Symptoms:
When an HTTP compression profile is enabled on BIG-IP platforms with Intel QuickAssist Technology (Intel QAT) compression accelerators, gzip errors are produced.

Conditions:
This occurs when the following conditions are met:

-- The following platforms with Intel QAT are affected:
   + 4450 blades
   + i4600/i4800
   + i10600/i10800
   + i7600/i7800
   + i5600/i5800
   + i11600/i11800
   + i11400/i11600/i11800
   + i15600/i15800

-- The compression.qat.dispatchsize variable is set to any of the following values:
   + 65535
   + 32768
   + 16384
   + 8192

-- The size of the file being compressed is a multiple of the compression.qat.dispatchsize value, for exampld:

   + 65355*32768
   + 8192*32768

Impact:
Clients cannot decompress the compressed file because there is an invalid gzip footer.

Workaround:
Disable hardware compression and use software compression.


872165-4 : LDAP remote authentication for REST API calls may fail during authorization

Links to More Info: BT872165

Component: TMOS

Symptoms:
LDAP (or Active Directory) remote authentication fails during authorization for REST API calls.

Clients receive 401 Unauthorized messages and /var/log/restjavad.x.log may report messages similar to the following:

-- [I][1978][26 Mar 2021 13:23:36 UTC][8100/shared/authn/login AuthnWorker] User remoteuser failed to login from 192.0.2.1 using the tmos authentication provider

-- [WARNING][807][26 Mar 2021 14:43:24 UTC][RestOperationIdentifier] Failed to validate Authentication failed.

Conditions:
LDAP (or Active Directory) remote authentication configured with a User Template instead of a Bind Account.

Impact:
Unable to authenticate as remote-user for access that uses authorization, like REST API calls.

Workaround:
You can use either of the following workarounds:

-- Configure LDAP/AD remote authentication to utilize a Bind account instead of the User Template.
-- Create a local user account for each remote user, allowing local authorization (authentication remains remote).


869049-7 : Charts discrepancy in AVR reports

Links to More Info: BT869049

Component: Application Visibility and Reporting

Symptoms:
Discrepancy in AVR reports. When filtering on the 'last month' interval, a specific number of total requests per virtual server is shown. Then when filtering to the present day from a date that encompasses that month, a lower number is reported.

Conditions:
-- Number of records in database exceeds the maximum mount of data that AVR can aggregate between different table-resolutions.
-- There are metrics on the report other than the default one (hits-count).

Impact:
Stats on DB get corrupted and incorrect.

Workaround:
None.


868557-1 : Unable to initiate SWG database download from Admin UI when management network has no direct internet connectivity.

Component: Access Policy Manager

Symptoms:
If the management network is not directly connected to the internet, 'Download Now' action on 'Access ›› Secure Web Gateway : Database Settings : Database Download' fails the connectivity check and refuses to start database download.

Conditions:
-- Configure proxy in the same subnet and block BIG-IP management traffic on the gateway
-- Remove default routes from linux routing table and add route to the proxy server if necessary.

Impact:
Database download fails and you see an error message:

"Database download server (download.websense.com) could not be reached. Please verify the correctness of the DNS lookup server configured on this BIG-IP system."

Workaround:
-- Run the following tmsh command:
tmsh modify sys url-db download-schedule urldb download-now true

-or-

-- Configure download settings and wait until the scheduled database download.


867985-6 : LTM policy with a 'shutdown' action incorrectly allows iRule execution

Links to More Info: BT867985

Component: Local Traffic Manager

Symptoms:
BIG-IP systems provide manipulation tools over a connection with an LTM policy and/or iRule. LTM policy takes precedence over iRules and has an option to shutdown a connection based on satisfied conditions. When a connection is closing, an iRule should not be executed under the same conditions.

Conditions:
-- The BIG-IP system has a virtual server with an LTM policy and an iRule.
-- The LTM policy has action 'shutdown connection' under certain conditions.
-- The iRule has an event which is triggered under the same conditions.

Impact:
The iRule is executed before the connection is being reset.

Workaround:
None.


867549-1 : LCD touch panel reports "Firmware update in progress" indefinitely&start;

Links to More Info: BT867549

Component: TMOS

Symptoms:
After a software upgrade that includes an LCD firmware update, the LCD touch panel may remain stuck reporting an error indefinitely / for longer than 30 minutes:
Firmware update in Progress may take up to 30 minutes.

Conditions:
This issue occurs when all of the following conditions are met:

-- You have one of the following BIG-IP platforms:
 * i850
 * i2x00
 * i4x00
 * i5x00
 * i7x00
 * i10x00
 * i11x00
 * i15x00
 * HRC-i2x00
 * HRC-i5x00
 * HRC-i10x00

-- You perform a software upgrade that updates the firmware on the LCD touch panel, e.g. upgrading from BIG-IP v13.1.x to BIG-IP v14.1.x or newer.

Impact:
The system is functional, but the LCD displays the firmware update screen indefinitely. The LCD cannot be used while it is frozen on the firmware update warning screen.

Workaround:
Important: Before attempting this workaround, check that there are no indications the system is still performing a firmware update (such as a terminal prompt), and that the following messages can be found in /var/log/ltm after the most recent boot:

notice chmand[6302]: 012a0005:5: firmware update succeeded.
notice chmand[6302]: 012a0005:5: Firmware check finished.

These messages indicates that the firmware update has finished, and the LCD is displaying the warning screen in error, so it is safe to perform the workaround.

Reboot the BIG-IP system to return the LCD to normal operation.

After a reboot of the BIG-IP operating system, the LCD touch panel should be responsive.


867253-4 : Systemd not deleting user journals

Links to More Info: BT867253

Component: TMOS

Symptoms:
When setting 'SystemMaxUse' to any value, systemd does not honor this limit, and the specified size is exceeded.

Conditions:
Using a non-TMOS user account with external authentication permission.

Note: Systemd-journald is configured to create a user journal for every remote user that logs into the BIG-IP system.

Impact:
Journald filling up the file system. These journals are allocated with a minimum size of 4MiB and are not removed when the log entries age-out.

Workaround:
Option 1:
To immediately free up space, manually remove per-user journal logs from the following location:
  /var/log/journal/*/user-*

Option 2:
To prevent the system from creating these journal files going forward:

1. Edit /etc/systemd/journald.conf and add the following at the bottom of the file:
  SplitMode=none

2. Restart systemd-journal service
  # systemctl restart systemd-journald

3. Delete the existing user journal files from /var/log
  # rm /var/log/journal/*/user-*

Note:
-- You must apply this workaround separately to each blade of a VIPRION or vCMP guest running on a VIPRION.
-- You must reapply this workaround after performing software installations.


865653-1 : Wrong FDB table entries with same MAC and wrong VLAN combination

Links to More Info: BT865653

Component: TMOS

Symptoms:
Forwarding DataBase (FDB) table has duplicate MAC entries with the incorrect VLANs.

MAC entries are correct in the switch but not in the control plane.

Conditions:
Enable L2Wire.

Impact:
Duplicate MAC entries with incorrect VLANs in FDB table.

Workaround:
Restart bcm56xxd:
bigstart restart bcm56xxd

Note: You can use tmsh to see the table:
tmsh -m show net fdb


862001-6 : Improperly configured NTP server can result in an undisciplined clock stanza

Links to More Info: BT862001

Component: Local Traffic Manager

Symptoms:
There can be an undisciplined clock stanza in /etc/ntp.conf, resulting in an undisciplined clock.

NTP documentation:
http://support.ntp.org/bin/view/Support/UndisciplinedLocalClock

Conditions:
This might occur in at least the following ways:
-- No server is specified in 'sys ntp servers {}'.
-- A server does exist, but an improper method was used to configure the NTP server.

Impact:
When the LOCAL undisciplined clock is left as a valid time-source, it delays the system synchronizing time to a real NTP server. It can also result in time being adjusted incorrectly if the the remote time-source becomes unreachable.

Workaround:
Configure a dummy server via 'ntp servers {}' that does not respond.

While this removes the undisciplined local clock, it does result in ntpd having an unreachable time source, and could be flagged in diagnostics, misdirect other troubleshooting, generate unnecessary traffic, etc.
 
However, if the 'dummy' source starts responding, it could become a rogue time source.


860573-6 : LTM iRule validation performance improvement by tracking procedure/event that have been validated

Links to More Info: BT860573

Component: TMOS

Symptoms:
Loading (with merge) a configuration file that references some iRules results in validating every iRule and ends up validating the same procedures multiple times for every virtual server a single iRule is associated with.

Conditions:
Configuration which has 100's of virtual servers, some iRules that are assigned to all virtual servers and a few library iRules.

Impact:
Task fails (via REST) or ends up taking a really long time when run manually.

Workaround:
None.

851837-1 : Mcpd fails to start for single NIC VE devices configured in a trust domain

Links to More Info: BT851837

Component: TMOS

Symptoms:
Single NIC BIG-IP Virtual Edition (VE) devices configured in a trust domain (e.g., in high availability (HA)) cannot reload a running configuration when restarted and/or when mcpd fails to load the config, and reports a validation error:

err mcpd[25194]: 0107146f:3: Self-device config sync address cannot reference the non-existent Self IP ([IP ADDR]); Create it in the /Common folder first.

Conditions:
Single NIC VE devices configured in a trust domain (e.g., HA)

Impact:
The mcpd process fails to start, and the configuration does not load.

Workaround:
Manually copy and paste the self IP configuration snippet into the /config/bigip_base.conf file:

net self self_1nic {
    address 10.0.0.1/24
    allow-service {
       default
    }
    traffic-group traffic-group-local-only
    vlan internal
}

Note: replace 10.0.0.1 with the IP indicated in the error message

3. Save the changes and exit.

4. Load the configuration using the command:
tmsh load sys config

5. If APM or ASM is provisioned/configured, then also restart services with this command:

851385-8 : Failover takes too long when traffic blade failure occurs

Links to More Info: BT851385

Component: Local Traffic Manager

Symptoms:
When blades 1 and 4 are disabled on the active chassis, the failover period is between 3.4 to 4.7 seconds before the next-active device starts processing messages.
  
If the blades are physically pulled from the chassis,
the failure occurs within 1 second.

Conditions:
-- Multi-blade VIPRION system
-- Blades 1 and 4 are connected to the network via trunks, blades 2 and 3 are CPU-only blades
-- Blades 1 and 4 are disabled via the GUI

Impact:
Significant delay before BIG-IP delivers a web page during between-cluster failover


851121-6 : Database monitor DBDaemon debug logging not enabled consistently

Links to More Info: BT851121

Component: Local Traffic Manager

Symptoms:
Debug logging in the database monitor daemon (DBDaemon) for database health monitors (mssql, mysql, postrgresql, oracle) is enabled on a per-monitor basis.
When a ping is initiated for a particular monitor with debug logging enabled in the monitor configuration, debug logging in DBDaemon is enabled.
When a ping is initiated for a particular monitor with debug logging disabled in the monitor configuration, debug logging in DBDaemon is disabled.
When monitoring database pool members with a mix of monitors with debug logging enabled vs. disabled, the result can be that debug logging in DBDaemon is enabled and disabled at times which do not correspond to all actions related to a specific database monitor, or pool members monitored by that monitor.
In addition, debug messages logging internal DBDaemon state related to the management of the full collection of monitored objects, active threads, etc. may not be logged consistently.

Conditions:
-- Using multiple database health monitors (mssql, mysql, postrgresql, oracle)
-- Enabling debug logging on one or more database health monitors, but not all

Debug logging for database health monitors is enabled by configuring the "debug" property of the monitor with a value of "yes".
Debug logging is disabled by configuring the "debug" property with a value of "no" (default).

# tmsh list ltm monitor mysql mysql_example debug
ltm monitor mysql mysql_example {
    debug yes
}

Impact:
Logging of database monitor activities by DBDaemon may be inconsistent and incomplete, impeding efforts to diagnose issues related to database health monitors.

Workaround:
When attempting to diagnose database health monitor issues with DBDaemon debug logging, enable debug logging for ALL database monitors currently in use.
Once diagnostic data collection is completed, disable debug logging for all database monitors currently configured/in use.


846977-7 : TCP:collect validation changed in 12.0.0: the first argument can no longer be zero&start;

Links to More Info: BT846977

Component: Local Traffic Manager

Symptoms:
Validation for TCP::collect was changed in BIG-IP software v12.0.0 (with the introduction of JET specifications). Prior to 12.0.0, there were no restrictions on the values of the two arguments. As of 12.0.0, the first argument ('collect_bytes') must be a positive integer, and the second argument ('skip_bytes) must be a non-negative integer.

Occurrences of 'TCP::collect 0 0' in iRules experience issues when upgrading to a newer version, producing warnings in LTM log:

/Common/T_collect:9: warning: [The following errors were not caught before. Please correct the script in order to avoid future disruption. "invalid argument 0; expected syntax spec:"136 17][TCP::collect 0 0].

Conditions:
-- Using a version of BIG-IP software earlier than 12.0.0, configure an iRule with a 'TCP::collect 0 0' command.
-- Upgrade to 12.0.0 or later.

Impact:
Warning in the LTM log file. The iRules containing 0 values do not function as expected. There is no other impact.

Workaround:
Change 'TCP::collect 0 0' to a value other than 0 (zero) in any iRules before or after upgrade.


844925-5 : Command 'tmsh save /sys config' fails to save the configuration and hangs

Links to More Info: BT844925

Component: TMOS

Symptoms:
The 'tmsh save /sys config' command hangs and fails to save the configuration if there is a memory allocation failure when creating the reply.

Conditions:
-- A large number of iApps: in the thousands.
-- Each iApp has tens of variables.

Impact:
Because tmsh cannot save the configuration, if the BIG-IP system reboots, any changes made since the last successful save are lost.

Workaround:
Run the command:
tmsh save /sys config binary

This does not save the configuration to files in /config, but it does at least allow you to save the binary configuration.

That way, you can reboot the BIG-IP system and not lose the configuration.

Note: It is possible that a reboot will provide sufficient memory to save to configuration files. It depends on the configuration of virtual memory at the time of the save. It is possible that every time you want to save the config, you must use the binary option.


843293-1 : When L7 performance FPGA is loaded, "tmsh show sys fpga" shows standard-balanced-fpga.

Links to More Info: BT843293

Component: TMOS

Symptoms:
When L7 performance FPGA is loaded, "tmsh show sys fpga" shows standard-balanced-fpga. "tmsh list sys fpga" will list the expected type "l7-performance-fpga".

Conditions:
-- iSeries i5000/i7000/i10000/i11000/i15000 platform
-- Pay as you grow (PAYG) license applied
-- L7 performance FPGA is loaded

Impact:
"tmsh show sys fpga" shows standard-balanced-fpga

This is cosmetic and there is no function impact. "tmsh list sys fpga" will list the correct type "l7-performance-fpga".

Workaround:
N/A


842669-6 : Syslog-ng / systemd-journald cannot handle logs with embedded newlines, write trailing content to /var/log/user.log

Links to More Info: BT842669

Component: TMOS

Symptoms:
Systemd-journald cannot handle logs with embedded newlines, write trailing content to /var/log/user.log. Bare ')' being logged to /var/log/user.log., for example:

cat /var/log/user.log
[...]: Deleting file /shared/core/*.core.*
[...]: Deleting file /shared/core/*.core.*
[...] )
[...] )

Conditions:
This occurs when the system logs syslog messages containing embedded newlines, such as

- The cron process tries and fails to send an email because of output from a cron script.
- Modifying the syslog 'include' configuration
- Applying ASM policy configuration change
- GTM.debugprobelogging output from big3d
- iqsyncer mcpd message debug output (log.gtm.level=debug)

Impact:
The logging subsystem accepts syslog messages with embedded newlines, and writes first line to the appropriate file, and remaining lines to /var/log/user.log.

Workaround:
View the logs using journalctl


842193-6 : Scriptd coring while running f5.automated_backup script

Links to More Info: BT842193

Component: iApp Technology

Symptoms:
When the iApp, f5.automated_backup, script is terminated due to the max-script-run-time, the script still continues and finishes, sometimes with scriptd coring and posting error messages in /var/log/ltm:

-- info logger[17173]: f5.automated_backup iApp autobackup: STARTED
-- info logger[17175]: f5.automated_backup iApp autobackup: pem.f5lab.com_20191004.ucs GENERATING

(/var/local/ucs)
-- info logger[19372]: f5.automated_backup iApp autobackup: FINISHED

Conditions:
Configure the iApp application with f5.automated_backup template to do auto-backup at regular intervals.

Impact:
Scriptd core.

Workaround:
Increasing the sys scriptd max-script-run-time higher then the default of 300 seconds might be helpful if the higher timeout allows the script to complete.

For example, if the script is saving a UCS and the save takes 400 seconds, then increasing the max-script-run-time to 430 seconds would allow the script to finish and would work around this issue.


839361-7 : iRule 'drop' command does not drop packets when used in DNS_RESPONSE

Links to More Info: BT839361

Component: Global Traffic Manager (DNS)

Symptoms:
The iRule 'drop' command may not drop a DNS response when called under DNS_RESPONSE event.

Conditions:
iRule drop is used under DNS_RESPONSE event.

Impact:
DNS response may be improperly forwarded to the client.

Workaround:
Use DNS::drop instead.


837101-3 : AVR and BIG-IQ stats show N/A bar for Source IP and domain name on DNS query packet

Links to More Info: BT837101

Component: Advanced Firewall Manager

Symptoms:
AVR and BIG-IQ stats show an N/A bar for Source IP and domain name fields on DNS query packets, while the correct IP and domain name is shown in other bars.

Conditions:
-- AFM is provisioned.
-- DNS traffic is processed.

Impact:
No functional impact, but incorrect and redundant results are shown in AVR.

Workaround:
None.


832133-7 : In-TMM monitors fail to match certain binary data in the response from the server.

Links to More Info: BT832133

Component: In-tmm monitors

Symptoms:
Pool members are incorrectly marked DOWN by a monitor. The pool members send the expected response to the probe, but the BIG-IP system still marks them DOWN.

Conditions:
This issue occurs when all of the following conditions are met:

-- In-TMM monitoring is enabled on the system (the 'bigd.tmm' db key is set to 'enable'; note this is set to 'disable' by default).

-- One (or more) of your TCP or HTTP monitors specifies a receive string using HEX encoding, in order to match binary data in the server's response.

-- Depending on the HEX values specified (currently values in the range of 0x80-0xBF are believed to be affected), response matching fails.

Impact:
Objects that are meant to be marked UP are marked DOWN. As a result, no load balancing occurs to affected resources.

Workaround:
You can use either of the following workarounds:

-- Disable in-TMM monitoring by setting 'bigd.tmm' to 'disable'.

-- Do not monitor the application through a binary response (if the application allows it).


831737-3 : Memory Leak when using Ping Access profile

Links to More Info: BT831737

Symptoms:
The memory usage by pingaccess keeps going up when sending request with expired session cookie to a virtual server with PingAccess Profile.

Conditions:
1. BIG-IP virtual server that contains PingAccess Profile.
2. Request sent with expired session cookie.

Impact:
Memory leak occurs in which ping access memory usage increases.


830073-7 : AVRD may core when restarting due to data collection device connection timeout

Links to More Info: BT830073

Component: Application Visibility and Reporting

Symptoms:
Avrd crashes, one or more core avrd files exist in /var/core

Conditions:
-- A BIG-IP system is managed by BIG-IQ via secure channel
-- Avrd is restarted.

Impact:
Avrd cores as it is shutting down. During avrd shutdown, the BIG-IQ data collection device (DCD) is unreachable for 10 minutes

Workaround:
None.


829657-5 : Possible TMM crash with a multi-IP PEM subscriber configured with more than 16 IP addresses

829021-1 : BIG-IP does not account a presence of http2 profile when response payload is modified

Links to More Info: BT829021

Component: Local Traffic Manager

Symptoms:
The BIG-IP system might close a connection when the HTTP response payload is modified and sent without chunking encoding. If communication goes over an HTTP connection, the BIG-IP system closes a connection to tell a client that a response is served. With HTTP/2 connections, an unsized response is marked with the END_STREAM flag. This case is not accounted for, and the BIG-IP system closes HTTP communication with a server anyway.

Conditions:
-- A virtual server has an http/2 profile configured on the client side.
-- There are other profiles configured which can modify the HTTP response payload.

Impact:
The BIG-IP system wastes resources not reusing a server side HTTP connection when an unsized response is sent over an HTTP/2 connection to a client.

Workaround:
None.


815901-2 : Add rule to the disabled pem policy is not allowed

Links to More Info: BT815901

Component: Policy Enforcement Manager

Impact:
You are unable to add rules to a PEM policy if it is disabled.


814273-6 : Multicast route entries are not populating to tmm after failover

Links to More Info: BT814273

Component: TMOS

Symptoms:
Multicast route entries are not populating in tmm after failover. ZebOS has the multicast entries, but tmm does not.

Conditions:
-- High Availability (HA) configured, with multicast traffic.
-- A failover occurs.

Impact:
Multicast traffic does not pass through properly

Workaround:
Clear the multicast entries in ZebOS manually:
> clear ip mroute *
> clear ip igmp group


812693-5 : Connection in FIN_WAIT_2 state may fail to be removed

Links to More Info: BT812693

Component: Local Traffic Manager

Symptoms:
If a connection that has a fully closed client-side, but a server-side still in FIN_WAIT_2, receives a SYN matching the same connflow, the idle time is reset. This can result in the fin-wait-2-timeout never being reached. The SYN will be responded to with a RST - 'TCP Closed'

Conditions:
- Client side connection has been fully closed. This may occur if a client SSL profile is in use and an 'Encrypted Alert' has been received.
- Server side has sent a FIN which has been ACK'd, but no FIN has been received from the server.
- SYN received matching the existing connflow before the FIN-WAIT-2-timeout has been reached (300 default).

Impact:
Connection may fail to be removed in a timely manner. New connection attempts are RST with 'TCP Closed'

Workaround:
You can use either of the following:
-- Ensure servers are sending FIN's so as not to leave the connection in a FIN_WAIT_2 state.

-- Mitigate the issue by lowering the FIN-WAIT-2-timeout to a smaller value, e.g., FIN-WAIT-2-timeout 10.


809089-4 : TMM crash after sessiondb ref_cnt overflow

Links to More Info: BT809089

Component: TMOS

Symptoms:
Log message that indicates this issue may happen:
session_reply_multi: ERROR: unable to send session reply: ERR_BOUNDS
[...] valid s_entry->ref_cnt

Conditions:
-- Specific MRF configuration where all 500 session entries are owned by a single tmm.

-- High rate of session lookups with a lot of entries returned.

Note: This issue does not affect HTTP/2 MRF configurations.

Impact:
TMM core: the program terminates with signal SIGSEGV, Segmentation fault. Traffic disrupted while tmm restarts.

Workaround:
1. Change MRF configuration to spread session lookups across multiple tmms.
2. Reduce the sub-key entries to far below 500.

808801-6 : AVRD crash when configured to send data externally

Links to More Info: BT808801

Component: Application Visibility and Reporting

Symptoms:
AVRD can crash repeatedly when configured to send telemetry data externally.

Conditions:
-- AVR is configured to send telemetry data to an external source (like connection with BIG-IQ).
-- Large number of config objects in the system, such as virtual servers and pool members.

Impact:
AVRD process crashes, and telemetry data is not collected.

Workaround:
Split the configuration updates into smaller batches


808481-6 : Hertfordshire county missing from GTM Region list

Links to More Info: BT808481

Component: TMOS

Symptoms:
Hertfordshire county is missing from Regions in the United Kingdom Country/State list.

Conditions:
-- Creating a GTM region record.
-- Attempting to select Hertfordshire county for the United Kingdom.

Impact:
Cannot select Hertfordshire county from United Kingdom Country/State list.

Workaround:
None.


807569-3 : Requests fail to load when backend server overrides request cookies and Bot Defense is used

Links to More Info: BT807569

Component: Application Security Manager

Symptoms:
When Bot Defense is used on the backend server that overrides request cookies, requests to non-HTML resources may fail, or may receive the whitepage JavaScript challenge. An example is when a back-end server responds with a Set-Cookie header containing empty values for each cookie request cookie it does not recognize.

Conditions:
-- Bot Defense is enabled.
-- Backend server is overriding the Bot Defense cookies with the TS prefix.

Impact:
Some URLs fail to load following the JavaScript challenge.

Workaround:
Use an iRule to strip the TSPD_101 cookie from the request before forwarding it to the backend:

when HTTP_REQUEST_RELEASE {
    HTTP::cookie remove "TSPD_101"
}


807309-5 : Incorrect Active/Standby status in CLI Prompt after failover test

Links to More Info: BT807309

Component: TMOS

Symptoms:
After running 'promptstatusd -y' to check current failover status, it displays an incorrect Active/Standby status in the CLI prompt.

Conditions:
This occurs under the following conditions:

1. Modify the db variable: bigdb failover.state.
2. Check that /var/prompt/ps1 and CLI prompt reflect the setting.
2. Reboot the BIG-IP system.

Impact:
Status shown in the prompt does not change.

Workaround:
Do not run 'promptstatusd -y' command manually.

The db variable 'failover.state is a status-reporting variable. The system does not report status manually set to something other than the actual status.

Note: 'promptstatusd' is not a BIG-IP user command, it is a daemon. It is highly unlikely that manually running this command will produce information that is useful or relevant to the status being sought.


806809-3 : JWT Claim value without quotes is invalid

Links to More Info: BT806809

Component: Access Policy Manager

Symptoms:
JSON payload is invalid since claims are generated without quotes(")

Conditions:
BIG-IP creates JWT claim value without quotes when scope is not openid.

Impact:
Token is invalid.

Workaround:
Replace claim type 'string' with 'custom' adding quotes after backslash.

apm oauth oauth-claim /Common/uid {
  claim-name uid
  claim-type custom
  claim-value "\"%{session.custom.name:noconv}\""

805561-1 : Change of pool configuration in OneConnect environment can impact active traffic

Links to More Info: BT805561

Component: Local Traffic Manager

Symptoms:
In OneConnect environments, when the default pool is updated for the first time, active connections reconnect to new pool members. Further update to pool configuration has no impact on traffic.

Conditions:
-- Virtual server configured with OneConnect profile.
-- Default pool is updated when active connections are present.

Impact:
Active traffic disrupted.

Workaround:
None.


804529-1 : REST API to /mgmt/tm/ltm/pool/members/stats will fail for some pools

Links to More Info: BT804529

Component: TMOS

Symptoms:
GET requests to REST endpoint /mgmt/tm/ltm/pool/members/stats may fail with error 404

Conditions:
This impacts pools which start with the letter 'm'. This because those endpoints contain objects with incorrect selflinks

For example
1. Query to below pool (that starts with letter 'm') will work as it contains the right selflink
       - Pool: "https://localhost/mgmt/tm/ltm/pool/~Common~m/stats"
       - selfLink: "https://localhost/mgmt/tm/ltm/pool/~Common~m/stats?ver=x.x.x.x"

2. Query to below pool (that does NOT start with letter 'm') may not work as it contains the wrong selflink
       - Pool: "https://localhost/mgmt/tm/ltm/pool/members/~Common~a/stats"
       - selfLink: "https://localhost/mgmt/tm/ltm/pool/members/~Common~a/stats?ver=x.x.x.x"
         
In above example you will notice the word 'members' shows up expectedly in selflink for case 2

Impact:
You may see errors with GET requests to REST endpoint /mgmt/tm/ltm/pool/members/stats

Workaround:
You may use the following workarounds

1. Use /mgmt/tm/ltm/pool/members/stats, which does return the pool member stats for every pool

2. For each pool member in /mgmt/tm/ltm/pool, issue a GET for:

/mgmt/tm/ltm/pool/<pool>/members/<member>/stats


803157-4 : LTM log contains shutdown sequence logs after boot_marker as logs are buffered until BIG-IP reboots

Links to More Info: BT803157

Component: TMOS

Symptoms:
In reboot case, the BIG-IP system buffers the shutdown sequence log messages and writes them to disk once the syslog service starts during the boot process. The boot_marker message is written before shutdown messages sync to disk. This leads to out-of-sequence log messages, making it difficult to determine when the service stop occurred.

Conditions:
Reboot the BIG-IP system.

Impact:
Log messages appear out of order. It is difficult to tell whether service stop happened as part of reboot, or any error during the subsequent boot process.

Workaround:
None.


798885-6 : SNMP response times may be long when processing requests

Links to More Info: BT798885

Component: TMOS

Symptoms:
SNMP queries to the BIG-IP system may take longer (up to 15% more time) to process on BIG-IP systems with large configurations. mcpd CPU usage increases by a small amount (up to 10%) during these queries.

Conditions:
-- Large configuration.
-- Using SNMP to query statistics on the BIG-IP system.

Impact:
A small increase in response time to SNMP requests to the BIG-IP. Some SNMP queries might fail due to timeouts. mcpd CPU usage is slightly elevated while processing these queries.

Workaround:
If the responses to SNMP queries are taking too long, MCPD and SNMPD may overburden the control plane. It may be necessary to lengthen the timeout and retry values used by the SNMP client. It may also be helpful to trim what is queried, for example, not repetitively walking large tables like the Virtual Server or LTM Pool Member tables for statistics.


797573-1 : TMM assert crash with resulting in core generation in multi-blade chassis

796985-4 : Default IPv4 IP address is assigned to Alt-Address in isolated vCMP guest; vCMP host or guest are upgraded and guest is 'Inoperative'&start;

Links to More Info: BT796985

Component: TMOS

Symptoms:
VCMP host or guest is upgraded, and the vCMP guest is 'Inoperative', with messages similar to the following in /var/log/ltm:

-- warning clusterd[1546]: 013a0005:4: Clusterd using /VERSION for SW specification.
-- info clusterd[1546]: 013a0023:6: Blade 1: No info received from slot: Starting up

-- notice clusterd[1546]: 013a0006:5: Disconnecting from mcpd.
-- info clusterd[1546]: 013a0007:6: clusterd stopping...

Conditions:
-- Isolated vCMP guest.
-- Both 'Address' and 'Alt-Address' are assigned the same IPv4 address.
-- Upgrade occurs.

Impact:
Upon host/guest upgrade, vCMP guest is 'Inoperative'.

Workaround:
-- For new vCMP guests, or prior to booting the vCMP guest to an affected version for the first time, assign it a management-ip from the vCMP host. This prevents the alt-address from being assigned and the issue from occurring on subsequent upgrades.

tmsh modify vcmp <guest_name> management-ip 192.168.1.246/24

-- For existing vCMP guests already on an affected version, but not currently experiencing the issue, assign a management-ip from the vCMP host and remove the alt-address from within the vCMP guest to prevent the issue from occurring in a future upgrade or reboot:

    host# tmsh modify vcmp guest <guest-name> management-ip 192.168.1.246/24

    guest# tmsh modify sys cluster default alt-address none

-- When already upgraded and seeing the issue on a guest, set a management-ip from the vCMP host and run the following commands within the guest to remove the alternate address from the configuration file:

    host# tmsh modify vcmp guest <guest-name> management-ip 192.168.1.246/24

    guest# bigstart stop clusterd
    guest# sed -i s/alt_addr=.*// -i /shared/db/cluster.conf
    guest# bigstart start clusterd

788257-5 : Bigd.mgmtroutecheck setting ignored by in-tmm monitors after bigstart restart

Links to More Info: BT788257

Component: In-tmm monitors

Symptoms:
The bigd.mgmtroutecheck db variable can be enabled to prevent monitor traffic from going through the management interface (for information, see K14549: Overview of the 'bigd.mgmtroutecheck' database key :: https://support.f5.com/csp/article/K14549); however, if in-tmm monitors are configured, the setting will be ignored after a bigstart restart.

Conditions:
-- bigd.mgmtroutecheck is enabled
-- bigd.tmm is enabled (i.e., in-tmm monitors are configured).
-- tmm has a route configured to the management interface.
-- A pool member exists that matches a route through the management interface.
-- bigstart restart is performed.

Impact:
In-tmm monitor traffic uses the management interface if there is a route to the pool member via the management interface, even when bigd.mgmtroutecheck indicates it is enabled.

Workaround:
None


780857-4 : HA failover network disruption when cluster management IP is not in the list of unicast addresses

Links to More Info: BT780857

Component: Local Traffic Manager

Symptoms:
If the cluster management IP address is not in the list of failover network unicast addresses, the blade management IP addresses in the unicast mesh will not be able to receive failover messages from peer devices.

Conditions:
-- VIPRION chassis or vCMP guest on a VIPRION chassis.
-- Per-blade management IP addresses listed in the failover network unicast mesh.
-- No cluster management IP address listed.

Impact:
The blade management IP addresses in the failover network unicast mesh stop functioning:

Workaround:
You can add an explicit management IP firewall rule to allow this traffic:

tmsh modify security firewall management-ip-rules rules add { accept_udp_1026 { place-before first ip-protocol udp destination { ports add { 1026 } } action accept } }

This will add a firewall policy so port 1026 is no longer locked down, and the blade management IP addresses in the unicast mesh should begin to function properly.


780745-5 : TMSH allows creation of duplicate community strings for SNMP v1/v2 access

Links to More Info: BT780745

Component: TMOS

Symptoms:
TMSH allows you to create multiple access records with the same IP protocol, same Source IP network, and same community string.

Conditions:
Duplicate access records are created in TMSH.

Impact:
Unintended permissions can be provided when an undesired access record with the correct community string is matched to a request instead of the desired access record.

Workaround:
Use the Configuration Utility to manage SNMP v1/2c access records. (The GUI properly flags the error with the message:
The specified SNMP community already exists in the database.

If you use tmsh, ensure that community strings remain unique within each Source IP Network for each IP protocol.


780437-8 : Upon rebooting a VIPRION chassis provisioned as a vCMP host, some vCMP guests can return online with no configuration.

Links to More Info: BT780437

Component: TMOS

Symptoms:
It is possible, although unlikely, for a vCMP host to scan the /shared/vmdisks directory for virtual disk files while the directory is unmounted.

As such, virtual disk files that existed before the reboot will not be detected, and the vCMP host will proceed to create them again.

The virtual disks get created again, delaying the guests from booting. Once the guests finally boot, they have no configuration.

Additionally, the new virtual disk files are created on the wrong disk device, as /shared/vmdisks is still unmounted.

Symptoms for this issue include:

-- Running the 'mount' command on affected host blades and noticing that /shared/vmdisks is not mounted.

-- Running the 'tmsh show vcmp guest' command on affected host blades (early on after the reboot) and noticing some guests have status 'installing-vdisk'.

-- Running the 'lsof' command on affected and unaffected host blades shows different device numbers for the filesystem hosting the virtual disks, as shown in the following example (note 253,16 and 253,1):

qemu-kvm 19386 qemu 15u REG 253,16 161061273600 8622659 /shared/vmdisks/s1g2.img

qemu-kvm 38655 qemu 15u REG 253,1 161061273600 2678798 /shared/vmdisks/s2g1.img

-- The /var/log/ltm file includes entries similar to the following example, indicating new virtual disks are being created for one of more vCMP guests:

info vcmpd[x]: 01510007:6: VDisk (s2g1.img/2): Adding.
info vcmpd[x]: 01510007:6: VDisk (s2g1.img/2): Syncing with MCP - [filename:s2g1.img slot:2 installed_os:0 state:0]

info vcmpd[x]: 01510007:6: VDisk (s2g1.img/2): Syncing with MCP - [filename:s2g1.img slot:2 installed_os:0 state:2]

Conditions:
-- VIPRION chassis provisioned in vCMP mode with more than one blade in it.

-- Large configuration with many guests.

-- The VIPRION chassis is rebooted.

-- A different issue, of type 'Configuration from primary failed validation' occurs during startup on one or more Secondary blades. By design, MCPD restarts once on affected Secondary blades, which is the trigger for this issue. An example of such a trigger issue is Bug ID 563905: Upon rebooting a multi-blade VIPRION or vCMP guest, MCPD can restart once on Secondary blades.

Impact:
-- Loss of entire configuration on previously working vCMP guests.

-- The /shared/vmdisks directory, in its unmounted state, may not have sufficient disk space to accommodate all the virtual disks for the vCMP guests designated to run on that blade. As such, some guests may fail to start.

-- If you continue using the affected guests by re-deploying configuration to them, further configuration loss may occur after a new chassis reboot during which this issue does not happen. This occurs because the guests would then be using the original virtual disk files; however, their configuration may have changed since then, and so some recently created objects may be missing.

Workaround:
There is no workaround to prevent this issue. However, you can minimize the risk of hitting this issue by ensuring you are running a software version (on the host system) where all known 'Configuration from primary failed validation' issues have been resolved.

If you believe you are currently affected by this issue, please contact F5 Networks Technical Support for assistance in recovering the original virtual disk files.


779185-1 : Forward zone deleted when wideip updated

Links to More Info: BT779185

Component: Global Traffic Manager (DNS)

Symptoms:
When a forward zone is configured in zonerunner, and a wideip is configured in the same zone, BIG-IP may delete the bind zone whenever the wide ip's pool members are modified.

Subsequent modifications of the same zone will then result in a new primary zone being created in bind.

Conditions:
- A forward zone is configured in bind (zonerunner)
- The pool members associated with a wideip are modified

Impact:
Queries that do not match wideips are passed to bind for processing, and are no longer forwarded to the nameserver configured in the forward zone.

Workaround:
- Recreate the zonerunner forward zone after modifying the wideip

Configuring a network virtual server with a source address list causes the system to treat the virtual server as a host.

Conditions:
-- Configure a source address list on the virtual server.
-- Configure a network address for the destination of the virtual server (not an address list).

Impact:
Traffic does not flow to the virtual server as expected.

Workaround:
See K58807232


778501-5 : LB_FAILED does not fire on failure of HTTP/2 server connection establishment

Links to More Info: BT778501

Component: Local Traffic Manager

Symptoms:
When the server connection fails to be established due to server being down or actively rejecting the connection, LB_FAILED should fire and allow a new destination to be selected via iRule.

Conditions:
- iRule with LB_FAILED event
- server connection establishment fails

Impact:
Selection of a new destination via LB_FAILED is not possible, thus the client connection will be aborted.

Workaround:
No workaround available.


777389-7 : In rare occurrences related to PostgreSQL monitor, the mcpd process restarts

Links to More Info: BT777389

Component: TMOS

Symptoms:
Possible indications include the following:

-- Errors such as the following may appear in ltm/log:

   - notice postgres[10872]: [466-1] WARNING: pgstat wait timeout.
   - notice sod[27693]: 01140041:5: Killing /usr/bin/mcpd pid 7144.
   - BD_CONF|ERR| ...failed to connect to mcpd after 5 retries, giving up...
   - BD_CONF|ERR| ...can't read message from mcp conn, status:16908291.
   - BD_MISC|CRIT| ...Received SIGABRT - terminating.

-- Errors such as the following may appear in the dwbld/log:

   - Couldn't send BLOB notification - MCP err 16908291.
   - Got a terminate/abort signal - terminating ...
   - Terminating mcp_bridge thread.

-- Processes may restart unexpectedly, including mcpd, bd, and postgresql.

Conditions:
-- The 'mcpd' process attempts to read monitoring data from the PostgreSQL server, but no data is available.

-- A contributing factor might be that the AFM module is licensed but not configured.

Impact:
Failing to receive a monitoring response from the SQL server, MCPD goes into an infinite loop and skips the heartbeat report, resulting in its restart. While MCPD is restarting, the system is offline and does not process traffic. After restart, system operation returns to normal.

Workaround:
The chance of occurrence can be minimized by making sure that control-plane processes have sufficient memory to run efficiently.

}

config # tmsh restart sys service httpd
Stopping httpd: [ OK ]
Starting httpd: [FAILED]

Conditions:
Restarting httpd service using iControl REST API.

Impact:
Httpd fails to start.

Workaround:
To recover from the failed httpd state, you can kill all instances of the httpd daemon and start httpd:

killall -9 httpd

tmsh start sys service httpd

760355-4 : Firewall rule to block ICMP/DHCP from 'required' to 'default'&start;

Links to More Info: BT760355

Component: Advanced Firewall Manager

Symptoms:
If firewall is configured on the management port with an ICMP rule, after upgrading to v14.1.x or later, the ICMP rule does not work.

Conditions:
-- Firewall is configured on the management port.
-- Firewall is configured with an ICMP rule to block.

Impact:
ICMP packets cannot be blocked with a firewall rule to drop on management port. ICMP packets are allowed from the management port.

Workaround:
Run the following commands after upgrading to v14.1.x or later from earlier versions.

# /sbin/iptables -N id760355
# /sbin/iptables -I INPUT 1 -j id760355
# /sbin/iptables -A id760355 -i mgmt -p icmp --icmp-type 8 -s 172.28.4.32 -j DROP


760354-7 : Continual mcpd process restarts after removing big logs when /var/log is full

Links to More Info: BT760354

Component: TMOS

Symptoms:
The BIG-IP device suddenly stops passing traffic. You might see errors similar to the following:

err mcpd[15230]: 01070596:3: An unexpected failure has occurred, TAP creation failed (tmm): Permission denied - net/validation/routing.cpp, line 168, exiting...

Conditions:
This might occur when when /var/log is full and then you remove big logs.

Impact:
The mcpd process restarts continuously. This occurs because tmm blocks mcpd from restarting after /var/log fills up.

Workaround:
Empty the contents of big size log files under /var/log and reboot the BIG-IP system.

If that does not resolve the problem, restart all processes (bigstart restart) or reboot the box.


758491-5 : When using NetHSM integration, after upgrade to 14.1.0 or later (or creating keys using fipskey.nethsm), BIG-IP cannot use the keys

Links to More Info: BT758491

Component: Local Traffic Manager

Symptoms:
For Thales:
The ltm/log shows SSL handshake failures with similar lines (this is for Diffie-Hellman Key Exchange):

-- warning bigip1 tmm1[28813] 01260013 SSL Handshake failed for TCP 192.0.2.1:5106 -> 192.0.2.200:5607

For Safenet:
-- warning tmm1[17495]: 01260009:4: Connection error: ssl_hs_vfy_sign_srvkeyxchg:13544: sign_srvkeyxchg (80)
-- warning tmm1[17495]: 01260013:4: SSL Handshake failed for TCP 10.1.1.11:6009 -> 10.1.1.201:443
-- err pkcs11d[5856]: 01680002:3: Key table lookup failed. error.

Conditions:
1. Keys were created on earlier versions of BIG-IP software, no matter if using tmsh (Safenet) or using fipskey.nethsm (Thales, Safenet) and the device was upgraded to 14.1.0 or later.

2. Keys were created on BIG-IP v14.1.0 or later directly, using fipskey.nethsm (Thales). For Safenet, fipskey.nethsm was deprecated in 14.0.0.

Impact:
SSL handshake failures.

Workaround:
There are two workarounds:
-- Re-create the keys using tmsh command.

IMPORTANT: This workaround is suitable for deployments that are new and not in production.


-- Re-import the keys from nethsm using:
tmsh install sys crypto key <key_label> from-nethsm


You can find the key_label here:
-- The rightmost string in the output of the Thales command:
nfkminfo -l

-- The string after label= in the 'cmu list' command for Safenet.


757787-5 : Unable to edit LTM/AFM Policies that belong to an Application Service (iApp) using the WebUI.

Links to More Info: BT757787

Component: TMOS

Symptoms:
When creating a new rule or modifying an existing rule in a LTM/AFM Policy policy using the WebUI, the operation fails and an error similar to the following example is returned:

Transaction failed:010715bd:3: The parent folder is owned by application service (/Common/MyPolicy.app/MyPolicy), the object ownership cannot be changed to ().

Conditions:
-- The LTM/AFM Policy belongs to an Application Service (iApp).
-- The modification is attempted via the WebUI.

Impact:
Unable to make changes to existing LTM/AFM Policies.

Workaround:
Use the tmsh utility to make the necessary modifications to the LTM/AFM Policy. For example, the following command modifies an existing rule:

tmsh modify ltm policy myapp.app/Drafts/myapp_l7policy rules modify { 0 { conditions modify { 0 { http-method equals values { GET POST } } } } }


757486-2 : Errors in IE11 console appearing with Bot Defense profile

Links to More Info: BT757486

Component: Application Security Manager

Symptoms:
When Bot Defense profile is used and has Browser Verification enabled to either Verify Before Access, or Verify After Access, Microsoft Internet Explorer v11 (IE11) Browsers may display the following errors in the browser console:

HTML1512: Unmatched end tag.
a.html (26,1)
HTML1514: Extra "<body>" tag found. Only one "<body>" tag should exist per document.
a.html (28,1)

Conditions:
-- Bot Defense profile is enabled with Browser Verification.
-- End user clients are using the IE11 browser.

Impact:
Cosmetic error messages appear in an end user's browser console.

Workaround:
In order to work around this issue, inject the scripts to the '<body>' tag instead of the '<head>' tag. This can be done using this tmsh command:

tmsh mod sys db dosl7.parse_html_inject_tags value after,body,before,/body`


756830-6 : BIG-IP may fail source translation for connections when connection mirroring is enabled on a virtual server that also has source port set to 'preserve strict'

Links to More Info: BT756830

Component: TMOS

Symptoms:
The BIG-IP system may fail source translation for connections matching a virtual server that has connection mirroring enabled and source port selection set to 'preserve strict'.

Conditions:
Connections match a virtual server that has following settings:

- Connection mirroring is enabled.
- Source Port set to 'Preserve Strict'.

In addition, CMP hash selection (DAG mode) on the corresponding VLANs is set to 'Default DAG'.

Impact:
Source translation may fail on BIG-IP system, leading to client connection failures.

Workaround:
You can try either of the following:

-- Do not use the Source Port setting of 'Preserve Strict'.

-- Disable connection mirroring on the virtual server.


755207-3 : Large packets silently dropped on VE mlxvf5 devices

Links to More Info: BT755207

Component: TMOS

Symptoms:
Jumbo frames are disabled by default for Mellanox ConnectX-4 and ConnectX-5 devices using the mlxvf5 driver (i.e., many BIG-IP Virtual Edition (VE) configurations). Packets larger than 1500 bytes are silently dropped. Only packets up to 1500 bytes are supported when jumbo framers are disabled.

Conditions:
BIG-IP VE with SR-IOV using Mellanox ConnectX-4 or ConnectX-5 NICs.

Typically this represents VE configurations running on private Cloud environments such as VMware, KVM, OpenStack, and others.

Note: You can determine your environment by running the following commands:

# tmctl -d blade tmm/device_probed
# tmctl -d blade xnet/device_probed

Configurations exhibiting this issue either:

1. reports a value of 'mlxvf5' in the driver_in_use column in tmm/device_probed, and possibly reports 'tmctl: xnet/device_probed: No such table.'
2. reports a value of 'xnet' in the driver_in_use column in tmm/device_probed, and a value of 'mlxvf5' in the driver_in_use column in xnet/device_probed.

Impact:
Packets larger than 1500 bytes are dropped without a warning.

Workaround:
Enable jumbo frames and then restart tmm.

1. Add the following line to /config/xnet_init.tcl:
drvcfg mlxvf5 jumbo_support 1

2. Restart tmm:
bigstart restart tmm

Important: There are two possible mlxvf5 drivers. It is possible to enable jumbo frames only for the xnet-based driver.

Important: Enabling jumbo frames causes a performance loss for 1500-byte-size packet, but offers higher throughput at lower CPU usage for larger packets. Note that 1500 bytes is the most common size for internet packets.


753712-4 : Incorrect warning: Traffic Matching Criteria's inline source address has been set to any4 from any6 to match inline destination address' address family.

Links to More Info: BT753712

Component: TMOS

Symptoms:
An incorrect warning message is given when the inline source/dest address is changed:

-- warning mcpd[6927]: 01071859:4: Warning generated : Traffic Matching Criteria's inline source address has been set to any4 from any6 to match inline destination address' address family.

Conditions:
This occurs after you create a traffic-matching-criteria (port-list, address-list) with different source and destination addresses.

Impact:
An incorrect and confusing warning message is given. This warning does not affect traffic processing. It is inadvertently triggered when reading the configuration of the traffic matching profile. Virtual servers should continue to work, and the config should load as expected, despite the warning.

Workaround:
None

751451-4 : When upgrading to v14.0.0 or later, the 'no-tlsv1.3' option is missing from HTTPS monitors automatically created server SSL profiles

Links to More Info: BT751451

Component: Local Traffic Manager

Symptoms:
If there are HTTPS monitor objects that were created using BIG-IP software v12.x, when the BIG-IP is upgraded directly to v14.0.0 or later, the operation automatically creates server SSL profiles for the HTTPS monitors as needed. Those server SSL profile objects do not have 'no-tlsv1.3' included in their 'options' configuration.

Conditions:
-- Having HTTPS monitors configured in v12.x before upgrading.
-- Directly upgrading from v12.x to v14.0.0 or later

Impact:
TLSv1.3 gets enabled on the server SSL profiles.

Workaround:
-- To avoid this issue, upgrade from v12.x to v13.x, and then upgrade to v14.0.0 or later


-- To mitigate this issue, modify the affected profile to disable TLSv1.3.


749757-4 : -s option in qkview help does not indicate maximum size

Links to More Info: BT749757

Component: TMOS

Symptoms:
When running qkview with the -h option to obtain help, the -s (size) option is incorrectly rendered.

It should read:

[ -s <max file size> range:0-104857600 Bytes ]

Conditions:
-- Running qkview -h.
-- Viewing the -s (size) option help.

Impact:
The measurement size, bytes, is missing, which might result in confusion.

Workaround:
Use the -s option as normal, but be advised that the number should be in bytes, and that the maximum number is 104857600.

Conditions:
Use TMUI as the admin, or as a user with the administrator role, and either of the following:
-- Disable terminal access.
-- Restrict access to TMSH.

Impact:
Users with the Administrator role can obtain shell access via REST.

With terminal access disabled:
-- If you attempt to login using SSH, you will not be to do so.
-- If you make a POST request to the /mgmt/tm/util/bash endpoint with a body that includes a command to run, that command will be run.

With access to TMSH restricted:
-- A POST request to the /mgmt/tm/util/bash endpoint that includes a body with a command to run will be run.

Workaround:
None.


737692-5 : Handle x520 PF DOWN/UP sequence automatically by VE

Links to More Info: BT737692

Component: TMOS

Symptoms:
When BIG-IP VE is running on a host, there is the host interface's Physical Function (PF, the actual interface on the host device), and Virtual Function (VF, a virtual PCI device that is passed to the BIG-IP-VE). If an x520 device's PF is set down and then up, tmm does not recover traffic on that interface.

Conditions:
-- VE is using a VF from a PF.
-- The PF is set down and then up.

Impact:
VE does not process any traffic on that VF.

Workaround:
Reboot VE.


720610-4 : Automatic Update Check logs false 'Update Server unavailable' message on every run

Links to More Info: BT720610

Component: TMOS

Symptoms:
The Automatic Update Check operation erroneously logs a message indicating that the Update Server is unavailable on every run, successful or not.

Conditions:
The BIG-IP system is configured to run the Automatic Update Check feature.

Impact:
Misleading 'PHONEHOME: Update Server unavailable' messages in the log file, implying that the update server is not available.

Workaround:
None.


718291-4 : iHealth upload error does not clear

Links to More Info: BT718291

Component: TMOS

Symptoms:
If an error occurs that sets the iHealth error string, then this string is never cleared.

Conditions:
Setting an invalid hostname for db variable proxy.host.

Impact:
The system reports the following error string: curl: (56) Recv failure: Connection reset by peer. This error message is never cleared, despite running a successful upload. The bogus error message could result in unnecessary confusion after a successful upload.

Workaround:
To clear the error message, run the following command:
/usr/bin/guishell -c "update diags_ihealth_request set error_str='';"


717174-5 : WebUI shows error: Error getting auth token from login provider&start;

Links to More Info: BT717174

Component: Device Management

Symptoms:
Occasionally, the BIG-IP Admin Utility TMUI fails to function correctly and produces the following error:
Error getting auth token from login provider.

This occurs when the BIG-IP REST Daemon restjavad fails to start up properly.

Conditions:
This error most often occurs on the first or second boot after upgrade, and more often on Virtual Edition BIG-IP platforms running on oversubscribed or slow hypervisors.

Impact:
TMUI and any other BIG-IP system components that rely on REST Workers such as: OpenID Connect key rotation discovery, portions of the TMOS Web Configuration Utility, and Guided Configuration (AGC and WGC) fail to function properly.

Workaround:
Restarting the BIG-IP REST daemons restjavad and restnoded will usually correct the problem. To do so, connect to the SSH console and issue the following two commands:

bigstart restart restjavad
bigstart restart restnoded


714705-8 : Excessive "The Service Check Date check was skipped" log messages.

Links to More Info: BT714705

Component: TMOS

Symptoms:
Large numbers of these warnings are logged into the "ltm" file:

  warning httpd[12345]: 0118000a:4: The Service Check Date check was skipped.

The message appears whenever a new "httpd" instance is launched.

Conditions:
The BIG-IP instance has been installed with a "no service check" license. These licenses are sometimes provided with cloud pre-licensed VE software images.

Impact:
Log files are saturated with many useless warnings. This can hide actual problems and impede their diagnosis.

Workaround:
During manual troubleshooting, commands such as the following may be used to filter the excess warnings:

# grep -v 'Service Check Date check was skipped' ltm | less

The syslog-ng 'include' filter mechanism is another possibility, but this should be attempted only with assistance of the F5 Support team.


713183-7 : Malformed JSON files may be present on vCMP host

Workaround:
None.


712241-8 : A vCMP guest may not provide guest health stats to the vCMP host

Links to More Info: BT712241

Component: TMOS

Symptoms:
A vCMP guest usually provides the vCMP host with some guest health statistics as a convenience to the vCMP host administrator. These stats are:
-- mgmt/tm/sys/ha-status
-- mgmt/tm/sys/software/status
-- mgmt/tm/sys/software/provision

These tables are created by the host when host vcmpd queries the guest over the vmchannel using REST.

These RESTful queries may sometimes fail, causing the queried vCMP guest to be omitted in the display of the output of the following command: $ tmsh show vcmp guest

Conditions:
-- vCMP provisioned.
-- Guests are deployed.
-- Host vcmpd queries the guest over the vmchannel using REST.

Impact:
There is no functional impact to the guests or to the host, other than these lost tables.

-- Some vCMP guests may not show up in the output of the following command: tmsh show vcmp health
-- Some guests may appear with the wrong status in the GUI. Such as being grey when it should be green.
-- Files containing guest information, kept in:
/var/run/vcmpd/<guestname>/json/(sys-ha-status.json|sys-provision.json|sys-software.json) may be missing from that directory.
-- There might be files present there named using the following structure:
 /var/run/vcmpd/<guestname>/json/sys-(ha-status|provision|software).json.bad.

Workaround:
There is no workaround at this time.

Links to More Info: BT711747

Component: TMOS

Symptoms:
TMM restarts with core file available.

Conditions:
The issue occurs intermittently under the following conditions:

-- System uses pfmand.
-- pfmand health monitoring enabled (sys db pfmand.healthstatus value enable, this is the default).
-- The system is passing http traffic.
-- pfmand is reset (tmsh modify sys pfman device 0/00:0c.5 status reset).

Impact:
Traffic disrupted while TMM restarts.

Workaround:
N/A


708680-4 : TMUI is unable to change the Alias Address of DNS/GTM Monitors

Links to More Info: BT708680

Component: Global Traffic Manager (DNS)

Symptoms:
TMUI (the GUI) is unable to change the Alias Address of DNS/GTM Monitors.

Conditions:
-- Using the GUI.
-- DNS/GTM monitors with alias address.
-- Attempting to change the Alias Address.

Impact:
Cannot change the Alias Address.

Workaround:
Use tmsh.


705869-1 : TMM crashes as a result of repeated loads of the GEOIP database

Links to More Info: BT705869

Component: Global Traffic Manager (DNS)

Symptoms:
TMM crashes.

Conditions:
Repeatedly loading the GeoIP database in rapid succession.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Don't do repeated load of GeoIP Database.


703226-3 : Failure when using transactions to create and publish policies

Links to More Info: BT703226

Component: TMOS

Symptoms:
Use batch mode transactions to create Virtual Servers with Policies containing rules.

Conditions:
Create and publish in the same transaction a Policy containing rules.

Impact:
Operation fails.

This occurs because the system is trying to look up a policy that does not exist because the 'create' operation is not yet complete. This might happen when the create and publish operations occur simultaneously, which might happen in response to scripts from iApps, batch mode creation of policies, UCS load, upgrade operation--all try to create domain trust, and all might include the policy create in the same operation.

Workaround:
Separate the create Policy and publish Policy operations into two transactions when the Policy contains rules.


696363-7 : Unable to create SNMP trap in the GUI

Links to More Info: BT696363

Component: TMOS

Symptoms:
Trying to create a SNMP trap may fail in the GUI with the following error message: An error has occurred while trying to process your request.

Conditions:
-- Trap destinations are configured using the GUI: When trap destinations are configured in the GUI, the trap name is generated using the destination IP address.
-- Traps of the same destination address were previously created and deleted.

Impact:
GUI parameter checking does not work as expected. BIG-IP Administrator is unable to create a SNMP trap session.

Workaround:
To work around this issue when using the GUI, remove all traps that have the same destination address as the new one that failed. Then re-add your destination.

Tip: You can use tmsh to create/delete/modify SNMP traps, which enables viewing of the generated names, making it easier to understand what error has occurred.


691219-3 : Hardware syncookie mode is used when global auto last hop is disabled.

Links to More Info: BT691219

Component: TMOS

Symptoms:
When global auto last hop is disabled, for iSeries platforms (excluding i2xxx/i4xxx) and B4450 blades, hardware syncookie mode is used on SYN attack.

Conditions:
Global autohop is disabled. This setting is controlled by the following DB variable:

# tmsh list sys db connection.autolasthop
sys db connection.autolasthop {
    value "enable"
}

The default setting is enable.

Impact:
The virtual server can enter hardware syncookie mode, at which point responses will be routed using the incoming packet route. This can break configurations that are using asymmetric routing.

Workaround:
Disable hardware syncookies using the following DB variable:

# tmsh list sys db pvasyncookies.enabled
sys db pvasyncookies.enabled {
    value "true"
}

The default setting is true.


690928-6 : System posts error message: 01010054:3: tmrouted connection closed

Links to More Info: BT690928

Component: TMOS

Symptoms:
Beginning in BIG-IP 12.0.0, the tmrouted process pushes dynamic routes directly to the Traffic Management Microkernel (TMM). This message indicates the system is shutting down and is expected behavior during the reboot or shutdown process. The appearance of this message on a stable running system may indicate an issue with tmrouted functionality.

System posts the following message in /var/log/ltm: 01010054:3: tmrouted connection closed

Conditions:
This message occurs when all of the following conditions are met:

-- You have configured the BIG-IP system to use dynamic routing.
-- The BIG-IP system is in the process of shutting down or rebooting.

Impact:
This message is benign, unless you view the message on a stable running system. In this case, the message may indicate an issue with the tmrouted process.

Workaround:
None.


689147-6 : Confusing log messages on certain user/role/partition misconfiguration when using remote role groups

Links to More Info: BT689147

Component: TMOS

Symptoms:
When using remote role groups to set user/role/partition information, user login fails, but logs in /var/log/secure indicate that authentication was successful.

Errors similar to the following appear in /var/log/ltm:

-- User restriction error: The administrator, resource administrator, auditor and web application security administrator roles may not be restricted to a single partition.
-- Input error: invalid remote user credentials, partition does not exist, broken-partition

Errors similar to the following appear in /var/log/secure:

tac_authen_pap_read: invalid reply content, incorrect key?

Conditions:
Using remote role groups to set user/role/partition information for remote users, and either of the following:
-- A remote user is configured with the role of administrator, resource administrator, auditor, or web application security administrator, with access to a particular partition, rather than all. (These roles require access to all partitions.)
-- A remote user is configured with partition access set to a partition that does not exist on the BIG-IP system.

Impact:
The messages in /var/log/secure may be confusing and make it more difficult to diagnose the login failure.

Workaround:
Check /var/log/ltm for more specific error messages.


683534-2 : 'tmsh show sys connection' command prompt displaying 4 billion connections is misleading

Links to More Info: BT683534

Component: Local Traffic Manager

Symptoms:
The 'tmsh show sys connection' may present a prompt asking you to confirm you want to display ~4 billion (4,294,967,295) connections:

# show sys connection max-result-limit infinite

Really display 4294967295 connections? (y/n)

Conditions:
-- The 'tmsh show sys connection' command is executed with max-result-limit option set to infinite.

Impact:
The value shown in the prompt (4294967295) is misleading, and does not reflect the actual number of connections being handled by the system. The 4294967295 number represents the maximum value the field can hold, not the number of actual connections.

Workaround:
None


679316-8 : iQuery connections reset during SSL renegotiation

Links to More Info: BT679316

Component: Local Traffic Manager

Symptoms:
Error in /var/log/gtm:
err gtmd[14797]: 011ae0fa:3: iqmgmt_receive: SSL error: error:140940F5:SSL routines:SSL3_READ_BYTES:unexpected record

Conditions:
This occurs when a system tries to send data over the iQuery connection while the two endpoints are performing SSL renegotiation.

Note: iQuery connections automatically perform SSL renegotiation every 24 hours.

Impact:
The BIG-IP system is marked 'down' until the connection is reestablished. This usually takes no longer than one second.

Note: This is a subtly different issue from the one (with a very similar error, 140940F5 virtual server 140940E5) described in Bug ID 477240: iQuery connection resets every 24 hours :: https://cdn.f5.com/product/bugtracker/ID477240.html (K16185: BIG-IP GTM iQuery connections may be reset during SSL key renegotiation :: https://support.f5.com/csp/article/K16185).

This issue occurs even in versions where ID 477240 is fixed. There is no fix for this specific trigger of the same message.

Note: The iQuery communication issue is fixed through Bug ID 760471: GTM iQuery connections may be reset during SSL key renegotiation :: https://cdn.f5.com/product/bugtracker/ID760471.html.

Workaround:
There is no workaround at this time, but the problem is fixed via changes made in ID760471


674026-6 : iSeries AOM web UI update fails to complete.&start;

Links to More Info: BT674026

Component: TMOS

Symptoms:
Upon upgrading a BIG-IP version, AOM web UI updates can sometimes fail.

Conditions:
This occurs when upgrading a BIG-IP system's software version on iSeries platforms.

Impact:
After booting to a new version, the AOM web UI update fails with an error message in /var/log/ltm similar to the following:

err bmcuiupdate[20824]: Failed updated AOM web UI with return code 2

Workaround:
At the bash prompt run:

/etc/lcdui/bmcuiupdate

This triggers another upgrade attempt, and the result is logged in /var/log/ltm. This should not be service-affecting.


673952-6 : 1NIC VE in high availability (HA) device-group shows 'Changes Pending' after reboot

Links to More Info: BT673952

Component: TMOS

Symptoms:
When Virtual Edition (VE) is configured for 1NIC, you will see the following logs on reboot indicating that configuration has been loaded from file:

 notice tmsh[12232]: 01420002:5: AUDIT - pid=12232 user=root folder=/Common module=(tmos)# status=[Command OK] cmd_data=load sys config partitions all base
 notice tmsh[12392]: 01420002:5: AUDIT - pid=12392 user=root folder=/Common module=(tmos)# status=[Command OK] cmd_data=load sys config partitions all

Conditions:
- VE configured in 1NIC mode.
- Unit booted either through reboot or power on.

Impact:
This is unlikely to have any impact if the VE is in standalone mode but could result in an unexpected config if the configuration files differ.

If the VE is part of a device-group, then this will result in a commit id update and the units will show 'Changes pending'.

Workaround:
None.


673573-8 : tmsh logs boost assertion when running child process and reaches idle-timeout

Links to More Info: BT673573

Component: TMOS

Symptoms:
An idle-timeout occurs while running a sub-process in interactive mode, resulting in a log message. tmsh logs a benign but ominous-looking critical error to the console and to /var/log/ltm if a tmsh command reaches idle timeout and a spawned sub-process is still running.

The errors in /var/log/ltm begin with the following text:
    'boost assertion failed'

Conditions:
-- tmsh command reaches idle timeout.
-- Spawned sub-process is still running.

Impact:
Although the wording indicates a failure, the message is benign and you can safely ignore it.

Workaround:
None.

1. Gossip Framework : REST high availability (HA) sync framework will not work.
2. Licensing via BIG-IQ
3. selfLinks will be wrong

Conditions:
Changing the default management port of BIG-IP for httpd from 443 to anything else.

Impact:
BIG-IP will be unable to provide below functionality :
1. Gossip Framework : REST high availability (HA) sync framework will not work.
2. Licensing via BIG-IQ
3. selfLinks will be wrong
4. iAppLx, SSL Orchestrator, Access Guided Configuration, AS3 will be affected as these modules depends on Gossip

Workaround:
NA


662301-8 : 'Unlicensed objects' error message appears despite there being no unlicensed config

Links to More Info: BT662301

Component: TMOS

Symptoms:
An error message appears in the GUI:
This device is not operational because the loaded configuration contained errors or unlicensed objects. Please adjust the configuration and/or the license, and re-license the device.

Examination of the configuration and license shows that there are no configuration errors or unlicensed configuration objects. The device is operational.

Conditions:
The BIG-IP system is licensed and the configuration loaded.

Impact:
Error message appears in the GUI stating that the device is not operational. However, the device is operational.

Workaround:
On an appliance, restart mcpd by running the following command:

    bigstart restart mcpd

On a VIPRION or vCMP guest running on a VIPRION, restart MCPD on all blades by running the following command:

    clsh bigstart restart mcpd

Note: This causes a system to go offline while services restart. Traffic disrupted while services restart.


659579-6 : Timestamps in icrd, restjavad, and restnoded logs are not synchronized with the system time

Links to More Info: BT659579

Component: TMOS

Symptoms:
Logs on icrd, restnoded, and restjavad are in the UTC time zone and are not aligned to the system time, which makes it difficult to determine the time during troubleshooting operations.

Conditions:
Checking the icrd, restnoded, and restjavad logs timestamps.

Impact:
Difficult to troubleshoot as the logs are not aligned with system time.

Workaround:
None


658943-5 : Errors when platform-migrate loading UCS using trunks on vCMP guest

Links to More Info: BT658943

Component: TMOS

Symptoms:
During platform migration from a physical BIG-IP system to a BIG-IP vCMP guest, the load fails with one of these messages:

01070687:3: Link Aggregation Control Protocol (LACP) is not supported on this platform. Unexpected Error: Loading configuration process failed.

01070338:3: Cannot create trunk [name of trunk], maximum limit reached Unexpected Error: Loading configuration process failed.

Conditions:
-- The source device is a physical BIG-IP device with one or more trunks with or without LACP in its configuration.
-- The destination device is a vCMP guest.

Impact:
The platform migration fails and the configuration does not load.

Workaround:
You can use one of the following workarounds:

-- Remove all trunks from the source configuration prior to generation of the UCS.

-- Before loading the UCS archive onto the target BIG-IP, edit the archive and remove the trunk configuration from ./config/bigip_base.conf, and then repack the UCS.

-- After the UCS load fails, edit the configuration manually on the destination to remove trunk references, and then reload the configuration.


658850-6 : Loading UCS with the platform-migrate parameter could unexpectedly set or unset management DHCP

Links to More Info: BT658850

Component: TMOS

Symptoms:
When you load a UCS file using the platform-migrate parameter, the mgmt-dhcp value (enabled, disabled, or unset) will overwrite the value on the destination. Depending on the effect, this could change the destination's management IP and default management route.

If the UCS does not have mgmt-dhcp explicitly written out, note that its value is treated as the default for the local system, which varies by the type of system. On Virtual Edition (VE) platforms, the default is to enable DHCP. On all other platforms, the default is to disable DHCP.

Conditions:
This occurs when loading a UCS using the platform-migrate parameter:
tmsh load sys ucs <ucs_file_from_another_system> platform-migrate

Impact:
Changing the mgmt-dhcp value on the destination can result in management changing from statically configured to DHCP or DHCP to statically configured. This can result in loss of management access to the device, requiring in-band or console access.

Workaround:
There are a few ways to avoid this issue:

1. Specify the "keep-current-management-ip" parameter to the "load sys ucs" command, for instance:

tmsh load sys ucs <ucs_file_from_another_system> platform-migrate keep-current-management-ip

Note: The "keep-current-management-ip" parameter is undocumented and will not appear in context help or tab completion.

2. If you want to reset the target device to use a static IP, run the following commands after loading the UCS with the platform-migrate command:

tmsh modify sys global-settings mgmt-dhcp disabled
tmsh create sys management-ip <ip>/<mask>
tmsh delete sys management-route default
tmsh create sys management-route default gateway <ip>

Conditions:
This issue occurs when all of the following conditions are met:

-- The BIG-IP system is running v11.6.0 or earlier.
-- You configure a vCMP guest instance that is running BIG-IP v11.6.0 or later.
-- You have configured the vCMP guest instance with a hostname other than bigip1.
-- You deploy the vCMP guest instance.

Impact:
The vCMP guest does not use the configured hostname.

Workaround:
-- In tmsh, run the following commands, in sequence:

 mv cm device bigip1 HOSTNAME
 save sys config

-- Rename the device name in the GUI.

550526-3 : Some time zones prevent configuring trust with a peer device using the GUI.

Links to More Info: K84370515, BT550526

Component: TMOS

Symptoms:
AEST, AEDT, ACDT, ACWST, ACWDT, AWST, Asia/Muscat, and AWDT time zones prevent configuring trust with a peer device using the GUI.

Conditions:
-- Setting a BIG-IP system timezone to AEST, AEDT, ACDT, ACWST, ACWDT, AWST, Asia/Muscat, or AWDT.

-- Using the GUI to add a peer device to a trust configuration.

Impact:
Adding a peer device using the GUI fails.

Workaround:
You can use either of the following workarounds (you might find the first one easier):

-- Temporarily set the device timezone to a non-affected timezone (e.g.; UTC), establish trust, and set it back:

1. Navigate to System :: Platform.

2. Under 'Time Zone', select 'UTC', and click 'Update'

3. Repeat steps one and two to change all devices that are to be part of the trust domain.

4. Establish device trust by navigating to Device Management :: Device Trust :: Add all peers to be part of the trust domain.

5. Once trust is established, navigate to System :: Platform, and change Time Zone back to preferred time zone.

-- Use tmsh to add a peer device in these timezones: AEST, AEDT, ACDT, ACWST, ACWDT, AWST, Asia/Muscat, or AWDT.


547947-2 : Feeding empty username and password to the Logon Page followed by RadiusAuthAgent shows the session as Logged out

Links to More Info: BT547947

Component: Access Policy Manager

Symptoms:
Session logs out. No error messages or retry logon page.
---------------------------------------------

Your session is finished.

Logged out successfully.

Thank you for using BIG-IP.

To open a new session, please click here.
----------------------------------------------

Conditions:
Your environment has an access policy like the following

                                   Success
Start -> Logon Page -> Radius Auth ----> Advanced resource assign (webtop) -> allow.
                              |
                              | failure
                              -----------------------------------------------> Deny.

If you connect to the virtual server with this access policy and provide an empty username and password, you are logged out of the session and asked to open a new session page.

Impact:
Without providing proper username and password, user is shown the error "Logged out successfully.", which is improper.

Workaround:
No mitigation observed.


539648-4 : Disabled db var Watchdog.State prevents vCMP guest activation.

Links to More Info: K45138318, BT539648

Component: TMOS

Symptoms:
If a vCMP guest user disables the watchdog using the db variable Watchdog.State, then the vCMP guest does not reach a running state as reported by the vCMP host.

Conditions:
This occurs when the user sets sys db Watchdog.State value disable.

Impact:
vCMP guest fails to be operational.

Workaround:
Do not change the Watchdog.State db variable. The vCMP host requires the watchdog to monitor the guest health.


528314-2 : Generating new default certificate and key pairs for BIG-IP ssl profiles via CLI will not be reflected in GUI or in tmsh

Links to More Info: K16816, BT528314

Component: TMOS

Symptoms:
Using CLI to generate new default certificate and key pairs for BIG-IP ssl profiles are not reflected in GUI or in tmsh.

Conditions:
Using OpenSSL commands to generate a new default certificate and key pair, as described in SOL13579: Generating new default certificate and key pairs for BIG-IP ssl profiles, available here: https://support.f5.com/kb/en-us/solutions/public/13000/500/sol13579.html.

Impact:
After the renewal, tmsh list sys file ssl-cert default.crt command or the general properties in the GUI SSL Cert List shows the old one. This is a cosmetic issue only. The system uses the new default.

Workaround:
Perform a force reload of mcpd by running the following commands: -- touch /service/mcpd/forceload. -- tmsh restart sys service mcpd.


527119-9 : An iframe document body might be null after iframe creation in rewritten document.

Links to More Info: BT527119

Component: Access Policy Manager

Symptoms:
Cannot use certain page elements (such as the Portal Access menu) in Google Chrome, and it appears that JavaScript has not properly initialized, and results in JavaScript errors on the following kinds of code:
    iframe.contentDocument.write(html)
    iframe.contentDocument.close()
    <any operation with iframe.contentDocument.body>

Conditions:
-- The body of a dynamically created iframe document might be initialized asynchronously after APM rewriting.

-- Using the Chrome browser.

Impact:
Some JavaScript applications might not work correctly when accessed through Portal Access. For example, one of applications known to contain such code and fail after APM rewriting is TinyMCE editor.

Workaround:
Revert rewriting of the document.write call with a post-processing iRule.

The workaround iRule will be unique for each affected application.


499348-14 : System statistics may fail to update, or report negative deltas due to delayed stats merging.

Links to More Info: BT499348

Component: TMOS

Symptoms:
Under some conditions, the BIG-IP system might fail to report statistics over time. This can manifest as statistics reporting unchanging statistics (e.g., all zeroes (0)), or as sudden spikes in traffic, or as negative deltas in some counters.

The system performance graphs will also appear to have gaps / be missing data at the times that this occurs.

Conditions:
This occurs when there are frequent changes occurring to the underlying statistics data structures. This might occur under the following conditions:

-- The system is spawning/reaping processes on a frequent basis (e.g., when there is a large number of external monitors).

-- iRules are frequently using 'SSL::profile' to select different SSL profiles on a virtual server (this can cause per-virtual server, per-profile statistics to be created and deleted on a regular basis).

Impact:
Statistics fail to merge, which results in incorrect view of system behavior and operation.

Workaround:
This issue has two workarounds:

1. Reduce the frequency of changes in the statistics data structures. The specific action to take depends on what is triggering them. To do so, use any or all of the following:

 -- Reduce the frequency of configuration changes.
 -- Reduce the use of 'SSL::profile' in iRules.
 -- Reduce the number/frequency of processes being spawned by the system.

2. The second workaround has two parts:

a) Switch statistics roll-ups to the 'slow_merge' method, which causes the system to spend more CPU merging statistics. To do so, set the 'merged.method' DB key to 'slow_merge' using the following command:

    tmsh modify sys db merged.method value slow_merge

b) Change the merge-interval value to 2 to reduce CPU usage when merge-method is slow-merge.

    tmsh modify /sys db merged.merge.interval {value "2"}

Note: Performing the second workaround has the side-effect of disabling tmstat snapshots on the device. The tmstat snapshots are intended for F5-internal use only: the lack of snapshots will have no bearing on the functionality of your system; however, F5 Support might be impacted in their ability to troubleshoot issues on your system.


493740-4 : tmsh allows cipher group creation with non-existent "require" or "exclude" cipher rule.

Links to More Info: BT493740

Component: TMOS

Symptoms:
Using tmsh it is possible to create a cipher group referencing a non-existent cipher rule with tmsh even if this configuration is invalid.

Conditions:
Use tmsh to create a cipher group referencing a non-existent cipher rule using a command like this, where the 'require' or the 'exclude' directive comes after the 'allow' directive.

The non-existent cipher rule is "no-exist" in these examples:

tmsh create ltm cipher group test-group { allow add { f5-default } require add { no-exist } }

tmsh create ltm cipher group test-group { allow add { f5-default } exclude add { no-exist } }

Impact:
The result is an invalid configuration that can break configuration synchronisation between BIG-IP peers in some cases (after upgrades, or full configuration reload, for example).

Also, when navigating to the cipher group the GUI does not show it.

The GUI may also show this error:
"An error has occurred while trying to process your request. "

Workaround:
Use the GUI to create a new cipher groups.

When using tmsh, don't create a cipher group referencing a non-existent cipher rule.


475997-2 : SSL stream throughput slows down when hardware SSL offloading is in use

Links to More Info: K16687, BT475997

Component: Performance

Symptoms:
When performing LAN-speed transfers of large files (hundreds of MB) over SSL, or transfers of small ssl records, the throughput speed of the transfer significantly drops if the hardware SSL offloading is performed. The performance drop is from ~30% - ~50% depending on the cipher suite used.

Conditions:
This issue occurs when hardware SSL offloading is turned on.

Impact:
The performance degrades from ~30% - ~50% depending on the cipher suite used.

Workaround:
To work around this issue, you can modify the High-Speed Bridge (HSB) scheduler. To do so, perform the following procedure:

Impact of workaround: Performing the following procedure should not have a negative impact on your system.

Modifying the scheduler.hsbpollmode.ltm db key

Log in to the Traffic Management Shell (tmsh) by typing the following command:
tmsh

To set the db key value to always, type the following command:
modify /sys db scheduler.hsbpollmode.ltm value always

Save the changes by typing the following command:
save /sys config

DNS logging does not log Splunk format to HSL.

Workaround:
Use an iRule to send Splunk-formatted messages to the Splunk server.

For example:

ltm rule dns_logging_to_splunk {

   when DNS_REQUEST {
      set ldns [IP::client_addr]
      set vs_name [virtual name]
      set q_name [DNS::question name]
      set q_type [DNS::question type]

      set hsl [HSL::open -proto UDP -pool splunk-servers]
      HSL::send $hsl "<190>,f5-dns-event=DNS_REQUEST,ldns=$ldns,virtual=$vs_name,query_name=$q_name,query_type=$q_type"
   }

   when DNS_RESPONSE {
      set ldns [IP::client_addr]
      set vs_name [virtual name]
      set q_name [DNS::question name]
      set q_type [DNS::question type]
      set answer [DNS::answer]

      set hsl [HSL::open -proto UDP -pool splunk-servers]
      HSL::send $hsl "<190>,f5-dns-event=DNS_RESPONSE,ldns=$ldns,virtual=$vs_name,query_name=$q_name,query_type=$q_type,answer=\"$answer\""
   }
}


447522-1 : GUI: SNMPV3 Incorrectly requires "OID" when creating an SNMP user.

Links to More Info: BT447522

Component: TMOS

Symptoms:
The BIG-IP GUI incorrectly requires an OID to be specified when creating an SNMPv3 user.

Conditions:
Creating an SNMPv3 user via the BIG-IP GUI.

Impact:
An OID can be used to restrict the view that the user has to a particular branch of the tree, but should not be a required attribute.

Workaround:
- Enter a value of ".1" (with a leading dot) to allow access to all OIDs
(or)
- Create the user using tmsh instead of the GUI, where the oid-subset attribute is not mandatory.


431503-11 : TMSH crashes in rare initial tunnel configurations

Links to More Info: K14838, BT431503

Component: TMOS

Symptoms:
In rare BIG-IP configuration scenarios, TMM may crash during its startup process when the tunnel configurations are loaded.

Conditions:
During TMM startup, a tunnel is created, then immediately removed during the configuration load period, when TMM neighbor messages may be in flight via the tunnel. When the race condition fits, the neighbor message may land on an invalid tunnel.

Impact:
TMM crash in rare race conditions.

Workaround:
None.


382363-8 : min-up-members and using gateway-failsafe-device on the same pool.

Links to More Info: K30588577

Component: TMOS

Symptoms:
The system does not require setting a pool's min-up-members greater than 0 (zero) when also using gateway-failsafe-device on the same pool.

Conditions:
A pool's min-up-members is 0 when gateway-failsafe-device is set.

Impact:
Failure to set min-up-members greater than 0 when using gateway-failsafe-device might cause errors. The tmm might crash.

Workaround:
Set min-up-members greater than 0 when using gateway-failsafe-device.


369640-8 : iRules might return incorrect data when multiple partitions and/or folders contain objects with the same name

Links to More Info: K17195

Component: Local Traffic Manager

Symptoms:
iRules might return incorrect data when the BIG-IP configuration has folders or multiple administrative partitions that contain objects with the same name.

As a result of this issue, you may encounter one or more of the following symptoms:

 -- Client connections receive incorrect data.
 -- The BIG-IP system incorrectly load balances client connections.

Conditions:
This issue occurs when all of the following conditions are met:

 -- The configuration includes objects of the same name in different folders or administrative partitions
 -- An iRule references the object without using the fully-qualified path, e.g. "pool example_pool" instead of "pool /Common/folder1/example_pool"

Impact:
Client connections receive incorrect data, or are load balanced incorrectly.

Workaround:
To work around this issue, always specify full paths to objects referenced in iRules, e.g. instead of:
    pool example_pool
use:
    pool /Common/example_pool


349706-4 : NetworkAccess assigns 1.1.1.1 address to remote ppp endpoint APM VPN

Component: Access Policy Manager

Symptoms:
Network access sends 1.1.1.1 as X-VPN-serer-IP and Edge client reserves this IP for PPP communication with APM server.

Conditions:
-- VPN is configured on BIG-IP.
-- Edge Client/webtop is used to connect to VPN.

Impact:
If VPN is connected:
1. The user may not access the 1.1.1.1 address from the client machine.
2. if 1.1.1.1 is used as a dns server ip in Network Access configuration, DNS resolution may fail on the client machine.

Workaround:
NA


342319-1 : BIND forwarder server list and the recursion and forward options.

Component: TMOS

Symptoms:
When you add a Domain Name System (DNS) server to the BIND forwarder server list from the Configuration utility, the recursion option is set to no and the forward option is not set.

Conditions:
The parameters 'recursion yes' and 'forward only' are not being updated in named.conf when creating entries in the BIND Forwarder Server List from the GUI.

Impact:
This issue may cause some DNS queries that are sent to the BIG-IP system to fail.

Workaround:
You can work around this issue by setting the recursion and forward options. For more information, see SOL12224: Configuring the BIND forwarder server list does not correctly set additional options for the named.conf file, available here: http://support.f5.com/kb/en-us/solutions/public/12000/200/sol12224.html.


222220-8 : Distributed application statistics are not passed correctly.

Links to More Info: K11931

Symptoms:
Distributed application statistics include only requests passed to its first wide IP.

For BIG-IP versions 12.0.0 and later, distributed application statistics are always zero.

Conditions:
Viewing distributed application statistics on configurations with multiple wide-IP members.

Impact:
The system does not pass statistics for requests to all wide-IP members in the distributed application.

Note: For BIG-IP versions 12.0.0 and later, the system does not pass statistics for requests to any wide-IP-members in the distributed application.

Workaround:
None


1112649 : FIPS 140-2 compliant mode is incorrect after upgrade to 16.1.2.2&start;

Links to More Info: BT1112649

Component: TMOS

Symptoms:
After upgrading a BIG-IP system that is licensed for FIPS 140-2 compliant mode or with the full-box FIPS license, the FIPS mode reported is FIPS 140-3 compliant mode

Conditions:
-- BIG-IP system running a software version earlier than 16.1.2.2
-- FIPS 140-2 compliant mode or full-box FIPS license applied
-- Upgrade to version 16.1.2.2

Impact:
After the system reboots, the BIG-IP system reports that FIPS 140-3 compliant mode is enabled, but the FIPS mode might not necessarily be FIPS 140-3 compliant in this version.

Workaround:
If you are upgrading a BIG-IP system that has a FIPS 140-2 compliant mode license applied, instead upgrade to BIG-IP version 16.1.3 or higher.


1112089-1 : Prevent zrd from rolling back named.conf file in wrong situations

Component: Application Visibility and Reporting

Symptoms:
-- The tmsh utility may return an error when listing analytics configuration.

-- TMOS installations may fail and return an error.

-- Saving new UCS archives may fail and return an error.

In all cases, the error is similar to the following example:

TSocket::open() getaddrinfo() <Host: 127.3.0.2
 Port: 9090>Name or service not known
std exception: (Could not resolve host for client socket.), exiting...

Conditions:
-- Multi-blade VIPRION system (either metal or in the form of a vCMP guest).

-- AVR is provisioned.

-- At least one AVR scheduled-report is present in the configuration.

-- An action such as listing the config, saving a UCS archive, performing a TMOS installation, etc. is performed on a secondary blade.

Impact:
The operation you were attempting fails and an error is returned.

Workaround:

This is of course disruptive and may not be indicated for your site. If you require an Engineering Hotfix for this issue, please contact F5 Support.


1110949-2 : Updating certKeyChain of parent SSL profile using iControl does not change the cert and key outside certKeyChain of the child profile

Links to More Info: BT1110949

Component: Local Traffic Manager

Symptoms:
Invalid config after iControl call: the certificate and key of the child profile do not change as expected.

Conditions:
1. The SSL profile should default from a parent profile.
2. iControl REST is used to change the certkeychain of the parent profile.
3. The issue cannot be seen after the first call but from the second call, it's always reproducible.

Impact:
1. The child profile has an incorrect configuration.
2. The older certificate/key can not be deleted as they are still in use in the child profile.

Workaround:
Can use currently deprecated iControl call by using key and cert instead of certkeychain as follows:

curl -k -u admin:admin -H "Content-Type: application/json" -X PATCH https://10.155.75.246/mgmt/tm/ltm/profile/client-ssl/parent.example.com -d '{"key":"/Common/default.key","cert":"/Common/default.crt"}'

Instead of using DOSL7::disable, redirect non-HTTP traffic to a non-HTTP aware virtual server using the iRule command virtual <virtual_server_name>.


1110205-2 : SSL::collect in CLIENTSSL_DATA prevents orderly connection shutdown

Links to More Info: BT1110205

Component: Local Traffic Manager

Symptoms:
If a virtual server has an iRule performing SSL payload processing in CLIENTSSL_DATA, TMM fails to process or forward an ingress TCP FIN from a client, leaving the connection in a zombie state until it eventually idles out.

Conditions:
The issue occurs only when SSL::collect is used in CLIENTSSL_DATA

   when CLIENTSSL_DATA {
        log local0. "."
        SSL::release
        SSL::collect
    }

Impact:
Unexpected growth in the number of connections idling on a virtual server leads to memory pressure.

Workaround:
none

1108237-2 : Incorrect 'No reply from big3d: timed out' result for certain destinations monitored by GTM.

Links to More Info: BT1108237

Component: Global Traffic Manager (DNS)

Symptoms:
It is possible for monitor probes to a certain destination to be owned by no GTM device in the sync-group. As a result, no monitoring of the destination will be performed, and the monitored object will be incorrectly marked down with reason "no reply from big3d: timed out".

Conditions:
-- GTM sync-group with multiple GTM devices (including a sync-group that contains only a single GTM server with more than one GTM device in it).

-- Monitors specifying an explicit destination to connect to (e.g. with the property "destination 192.168.1.1:*").

-- The destination of a monitored object (e.g. the IP address of the gtm server) is different from the destination explicitly defined in a monitor assigned to the object.

-- The two mismatching destination values are assigned to different GTM devices in the sync-group for monitoring.

Impact:
Monitored GTM objects may have an incorrect status.

Workaround:
None


1108181-2 : iControl REST call with token fails with 401 Unauthorized

Links to More Info: BT1108181

Component: TMOS

Symptoms:
For a short period after creating or refreshing a token, iControl REST calls may fail with a 401 Unauthorized error and an HTML body content, or a 401 F5 Authorization Required error and a JSON body content.

When using F5 Ansible modules for BIG-IP, the modules may fail with an error "Expecting value: line 1 column 1 (char 0)".

AS3 may return an error, "AS3 API code: 401".

Conditions:
-- REST call using valid token.
-- Can commonly occur on the call after a token has been refreshed or a Token list has been requested.

Impact:
iControl REST calls may temporarily fail (typically less than 1 second) after the creation or refresh of an iControl REST token.

Workaround:
After being issued a token or refreshing a token, wait a second before attempting to use it.

If this does not work, request a new token.

No workaround exists for AS3 or F5 Ansible BIG-IP modules.

err sSMTP[9797]: Cannot open localhost:25

The symptoms are similar to what you see in https://support.f5.com/csp/article/K60914243 but the solution in that article will not help. K60914243 talks about 15.x while current issue is on 16.x.

Conditions:
This occurs in one of the following happens

1. You have manually deleted restjavad or restnoded log files with following commands
   rm /var/log/restjavad*
   rm /var/log/restnonded*

2. One of the restjavad/restnoded log files is small and unable to rotate (rotation fails). This happens when file size does not exceed default "max-file-size"

Impact:
Log rotation for restjavad/restnoded will be stuck. You may see system emails about sSMTP errors every 20 minutes.

Workaround:
This issue subsides if you manually create a file for the stuck log file.

1. Open a command terminal
2. Run # ls -l /var/log/restnoded*
3. If you find that restnonded1.log is missing then manually create it
    # touch /var/log/restnoded/restnoded1.log
4. Run # ls -l /var/log/restjavad*.log
5. If you find that restjavad.1.log is missing then manually create it

Invoking the iRule command 'reject' under the iRule event 'FLOW_INIT' may, in some cases, fail to send out the intended reject packet (i.e. TCP reset or ICMP port unreachable).

Conditions:
The issue occurs when the BIG-IP system does not have a route back to the client, and should instead deliver the reject packet by means of autolasthop.

Impact:
The connection is actually removed from the BIG-IP system's connection table, and correctly does not progress. However, the lack of a reject packet could make the client retransmit its initial packet or insist in opening more connections.


1101741-2 : Virtual server with default pool down and iRule pool up will flap for a second during a full config-sync.

Links to More Info: BT1101741

Component: TMOS

Symptoms:
During a full manual config-sync, a virtual server with a default pool which is down and an iRule pool which is up will flap for a second on the receiving unit.

For instance:

Apr 22 13:52:31 bigip-ntr-b.local notice mcpd[7733]: 01071682:5: SNMP_TRAP: Virtual /Common/my_vs has become unavailable
Apr 22 13:52:31 bigip-ntr-b.local notice mcpd[7733]: 010719e7:5: Virtual Address /Common/10.0.0.71 general status changed from GREEN to RED.
Apr 22 13:52:31 bigip-ntr-b.local notice mcpd[7733]: 010719e8:5: Virtual Address /Common/10.0.0.71 monitor status changed from UP to DOWN.
<...>
Apr 22 13:52:32 bigip-ntr-b.local notice mcpd[7733]: 01071681:5: SNMP_TRAP: Virtual /Common/my_vs has become available
Apr 22 13:52:35 bigip-ntr-b.local notice mcpd[7733]: 010719e7:5: Virtual Address /Common/10.0.0.71 general status changed from RED to GREEN.
Apr 22 13:52:35 bigip-ntr-b.local notice mcpd[7733]: 010719e8:5: Virtual Address /Common/10.0.0.71 monitor status changed from DOWN to UP.

Conditions:
-- device-group configured for full manual sync
-- virtual server with default pool up and iRule pool down
-- a config sync is initiated

Impact:
There is no impact to application traffic during the flapping, as the virtual server continues to function correctly even when the unit receiving the config-sync is the Active one.

However, the logs (and the ensuing SNMP traps) may be confusing to BIG-IP Administrators and/or network operators monitoring alarms from the system.

Workaround:
You can work around this issue by configuring the device-group for incremental config-sync instead (either manual or automatic).

1101181-2 : HTTP request payload not forwarded by BIG-IP when serverside is HTTP/2 and HTTP MRF router is enabled on virtual server

Links to More Info: BT1101181

Component: Local Traffic Manager

Symptoms:
The BIG-IP forwards HTTP request headers to pool member, but does not forward the request body. This results in a connection stall, and the connection eventually timing out and failing.

Conditions:
-- Virtual server with HTTP/2 full proxy configured (HTTP MRF router is enabled, and HTTP/2 profile present on virtual server).
-- Virtual server has request-logging profile assigned.
-- Serverside connection uses HTTP/2.
-- Client sends a request that includes a payload body (e.g. a POST).

Impact:
HTTP transaction fails; traffic does not pass.

Workaround:
Remove the request-logging profile.


1100669-3 : Brute force captcha loop

Links to More Info: BT1100669

Component: Application Security Manager

Conditions:
-- BIG-IP i4x00 platform.
-- TCP virtual server under SYN flood attack.

Impact:
Failed connections, service degradation.

Workaround:
Disabling SYN cookie in the TCP or fastL4 profile is a possible workaround, but that would leave the virtual server open to SYN flood attacks.

1099373-2 : Virtual Servers may reply with a three-way handshake when disabled or when processing iRules

Links to More Info: BT1099373

Component: Local Traffic Manager

Symptoms:
Virtual servers may complete a three-way handshake before resetting a connection when they are disabled or when iRules process traffic for disabled virtual servers.

Conditions:
-- Virtual Server with a pool assigned
-- Pool is disabled administratively

Impact:
When a virtual server is marked as disabled and a client attempts to connect to it, tmm will normally send a reset to the first SYN packet. However, if you then administratively disable the pool ( disabled pool members - Not forced offline) tmm will complete the three-way handshake before sending resets. Additionally, when in this state, iRules will process and can pass traffic to pools if the iRule is configured to do that even though the virtual server status is disabled.

Workaround:
Avoid marking pools disabled or use forced offline for virtual servers that you want to administratively disable.

1097193-2 : Unable to SCP files using WinSCP or relative path name

Links to More Info: BT1097193

Component: TMOS

Symptoms:
When attempting to retrieve a file with WinSCP, you receive an error dialog and the session will be terminated:

"SCP Protocol error: Invalid control record (r; elative addresses not allowed)

Copying files from remote side failed."

If attempting to transfer a file by relative path with a command line utility the transfer will fail with the message:
"relative addresses not allowed"

Conditions:
-- Running BIG-IP version with fix for ID 915981
-- Using WinSCP set to use SCP protocol to retrieve files from a BIG-IP system.
-- Using a relative remote path to transfer a file with command line scp utility.

Impact:
No longer able to use WinSCP to retrieve files such as packet captures, log archives, or other diagnostic data from the BIG-IP system.

Workaround:
Use a command line SCP tool that allows specifying an absolute path for the source and/or destination file (a path that starts with a forward slash /), when the source and/or destination locations are a BIG-IP device.

If the user ID is permitted to do so, you may use WinSCP in SFTP mode.


1096893-1 : TCP syncookie-initiated connections may end up unexpectedly IP-fragmenting packets mid-connection

Links to More Info: BT1096893

Component: Local Traffic Manager

Symptoms:
When route metrics are applied by the TCP filter to a connection initiated by a syncookie, TCP sets the effective MSS for packetization, thereafter the egress_mtu will be set as per the route metrics entry, if present. The packets falling between the effective MSS and the lowered egress_mtu end up being unexpectedly IP-fragmented.

Conditions:
SYN cookies enabled and activated. A route metrics PMTU entry for the destination address that is smaller than the VLAN's egress MTU.

Impact:
Application traffic can fail or see disruption due to unexpected IP fragmentation.

Workaround:
Disable syn cookies (Reference: https://support.f5.com/csp/article/K80970950).

Alternatively, you can apply a lower static MTU to the interface.

1091249-2 : BIG-IP DNS and Link Controller systems may use an incorrect IPv6 translation address.

Links to More Info: BT1091249

Component: Global Traffic Manager (DNS)

Symptoms:
As BIG-IP DNS and Link Controller systems connect with one another (or with monitored BIG-IP systems) over iQuery, you may notice:

-- Log messages that specify IPv6 translation addresses non-existent in your configuration and often meaningless (as in not pertaining to some of the more common IPv6 address spaces). For example:

debug gtmd[24229]: 011ae01e:7: Creating new socket to connect to 2001::1 (a06d:3d70:fd7f:0:109c:7000::)

-- If you restart the gtmd daemon, the IPv6 translation address mentioned above between parenthesis changes to a new, random meaningless value.

-- The GTM portion of the configuration fails to synchronize.

Conditions:
IPv6 translation addresses are in use in relevant objects.

Impact:
The logs are misleading and the GTM portion of the configuration may fail to synchronize.

Workaround:
If possible, do not use IPv6 translation addresses.


1091021-2 : The BIG-IP system may take no fail-safe action when the bigd daemon becomes unresponsive.

Links to More Info: BT1091021

Component: Local Traffic Manager

Symptoms:
You may observe LTM monitors are malfunctioning on your system. For instance, you may notice some probes are not sent out on the network, and some monitored objects are showing the wrong status.

Conditions:
-- The bigd daemon consists of multiple processes (which you can determine by running "ps aux | grep bigd").

-- One or more of the processes (but not all of them) becomes disrupted for some reason, and stops serving heartbeats to the sod daemon.

Under these conditions, sod will not take any fail-safe action and the affected bigd processes will continue running impaired, potentially indefinitely.

Impact:
LTM monitoring is impacted.

Workaround:
If you have determined, or if you suspect, this issue is present on your system, you can resolve it by killing all bigd processes using the following command:

pgrep -f 'bigd\.[0-9]+' | xargs kill -9

However, this does not prevent the issue from manifesting again in the future if the cause for bigd's disruption occurs again.

Monitoring may become further disrupted as bigd restarts, and a failover may occur depending on your specific configuration.

1088597-2 : TCP keepalive timer can be immediately re-scheduled in rare circumstances

Links to More Info: BT1088597

Component: Local Traffic Manager

Symptoms:
In rare circumstances, the TCP timer is rescheduled immediately due to the utilization of the interval encompassing also the idle_timeout.

Conditions:
Virtual Server with:

- TCP Profile
- SSL Profile with alert timeout configured

Another way this can occur is by manually deleting connections, which effectively only sets the idle timeout to 0.

Impact:
High CPU utilization potentially leading to reduced performance.

Workaround:
If the alert timeout is not re-enabled in the SSL Profile that should be sufficient.


1088173-2 : With TLS 1.3, client Certificate is stored after HANDSHAKE even if retain-certificate parameter is disabled in SSL profile

Workaround:
None


1087569-4 : Changing max header table size according HTTP2 profile value may cause stream/connection to terminate

Links to More Info: BT1087569

Component: Local Traffic Manager

Symptoms:
BIG-IP initializes HEADER_TABLE_SIZE to the profile value and thus when it exceeds 4K (RFC default), the receiver's header table size is still at the default value. Therefore, upon receiving header indexes which has been removed from its table, receiver sends GOAWAY (COMPRESSION_ERROR)

Conditions:
-- HTTP2 profile used in a virtual server
-- In the HTTP2 profile, 'Header Table Size' is set to a value greater than 4096

Impact:
Stream/connection is terminated with GOAWAY (COMPRESSION_ERROR)

Workaround:
Issue can be avoided by restoring the header-table-size value to the default of 4096

1086517-2 : TMM may not properly exit hardware SYN cookie mode

Links to More Info: BT1086517

Component: TMOS

Symptoms:
Due to a race condition, when one TMM exits SYN cookie mode, another may immediately re-enter hardware SYN cookie mode, keeping the virtual server in SYN cookie mode and the mitigation offloaded to hardware. The SYN cookie status of the virtual server is not properly updated and will show 'not-activated'.

Conditions:
Hardware SYN cookie protection is enabled and SYN cookie mode is triggered.

Impact:
A virtual server that once entered hardware SYN cookie mode may remain in that state indefinitely. The reduced MSS size may affect performance of that virtual server.

Workaround:
Disable hardware SYN cookie either locally via the TCP or FastL4 profile, or globally by the PvaSynCookies.Enabled BigDB variable. Software SYN cookie mode is unaffected.


1086473-3 : BIG-IP resumes a TLS session on the client-side but then proceeds to do a full handshake

Links to More Info: BT1086473

Component: Local Traffic Manager

Symptoms:
When a client attempts to resume the TLS session using the Session-ID in its Client Hello from a previous session, the BIG-IP agrees by using the same Session-ID in its Server Hello, but then proceeds to perform a full handshake (Server Hello, Certificate, Server Key Exchange, Certificate Request, Server Hello Done) instead of an abbreviated handshake (Server Hello, Change Cipher Spec, Server Hello Done).

This is a violation of the TLS RFC.

Conditions:
- High availability (HA) pair of two BIG-IP units.
- LTM virtual server with a client-ssl profile.
- Mirroring enabled on the virtual server

Impact:
Client-side TLS session resumption not working.

Workaround:
Disable mirroring on the virtual server


1085837-2 : Virtual server may not exit from hardware SYN cookie mode

Links to More Info: BT1085837

Component: TMOS

Symptoms:
Once a virtual server enters hardware SYN cookie mode it may not exit until a TMM restart.

Conditions:
-- On B2250 and B4450 platforms.
-- A condition triggers SYN cookie mode and then goes back to normal.

Impact:
-- Virtual servers in hardware SYN cookie mode do not receive TCP SYN packets.
-- The limited number of possible TCP MSS values may have a light performance impact.

Workaround:
Disable hardware SYN cookie mode on the affected objects.


1085805-2 : UCS restore with SSL Orchestrator deployed fails due to multiple iFiles and incorrect iFile reference.

Links to More Info: BT1085805

Component: TMOS

Symptoms:
The UCS restore process with SSL Orchestrator deployment fails due to multiple iFiles. This happens because the UCS restore process does not clean up the existing iFile belonging to SSL Orchestrator. On restore, the BIG-IP system contains two iFiles, one created as a part of the UCS and the other existing iFile belonging to SSL Orchestrator.

Additionally, the path in the rest storage referencing the iFile object does not get updated.

In the bigip.conf, the iFile version does not point to the iFile that is restored as part of the UCS restore process.

To check the reference in restDB use the following https://<<MGMT-IP>>/mgmt/tm/sys/file/ifile/~Common~ssloF_global.app~SSL OrchestratoriFile?options=-hidden.

Conditions:
-- UCS contains SSL Orchestrator deployment
-- iFile version number in the UCS and on the BIG-IP before restoring the UCS is different.
-- Multiple iFile which belongs to SSL Orchestrator after restore. This can be verified by executing below command on the box
ll /config/filestore/files_d/Common_d/ifile_d/ | grep SSL Orchestrator

Impact:
-- Error in the SSL Orchestrator UI.
-- You are unable to make changes via the SSL Orchestrator UI.

Workaround:
Mitigation depends on user state.

State 1: when you know that a restore will cause multiple iFile creation, use the following.

Before restoring the UCS file, perform the following steps:

a) Delete the iFile object using the following command. Do not create any configuration using SSL Orchestrator UI after deleting the iFile.

tmsh delete sys application service ssloF_global.app/ssloF_global

b) Restore the UCS.


State 2: when you already tried the UCS restore and it is in error state, use the following

a) On UCS restore when the system is in an error state, use the following command to verify multiple files:
ll /config/filestore/files_d/Common_d/ifile_d/ | grep SSL Orchestrator

b) Use the following commands, to delete the multiple iFiles:
tmsh delete sys application service ssloF_global.app/ssloF_global

rm -fr /config/filestore/files_d/Common_d/ifile_d/\:Common\:ssloF_global.app\:SSL OrchestratoriFile_*

c) Restore the UCS

1080317-3 : Logged hostname not consistent when hostname contains "."

Links to More Info: BT1080317

Component: TMOS

Symptoms:
Messages which are logged to journald use the configured hostname while sylog-ng uses the hostname (machine name) and truncates it starting at the first '.'. As we're using a mix of logging directly to syslog-ng (e.g., /var/run/tmm.pipe) and from journald, this results in hostnames being inconsistent when it contains '.'; i.e., "my.hostname" is logged as "my" by syslog-ng and "my.hostname" by journald. This can make it difficult for log analysis tools to work with the log files.

Conditions:
When hostname contains '.'

Impact:
Not in readable state as some logs contains truncated hostname and some contain full hostname

1079237-1 : After certain configuration tasks are performed, TMM may run with stale SNAT translation parameters.

Links to More Info: BT1079237

Component: Local Traffic Manager

Symptoms:
A SNAT translation object instantiated by performing specific configuration tasks (see Conditions) does not work.

For example:

- Connections might be reset with cause "No available SNAT addr".

- An unexpected IP address might be used to SNAT the outgoing traffic.

Conditions:
This issue is known to occur when one of the following operations is performed:

- Restoring a UCS or SCF archive in which a SNAT translation with a specific name specifies a different IP address or route domain.

- Performing a config-sync between redundant units in which the sender changes a SNAT translation with a specific name to use a different IP address or route domain.

- Performing specific tmsh CLI transactions involving SNAT translation modifications.

Impact:
The system does not use the configured SNAT translation address. Traffic will be impacted as a result (for example, reset connections or incorrect source IP address in outgoing traffic).

Workaround:
Restart TMM (bigstart restart tmm) on affected units.

1078357-2 : HTTP_REJECT processing can lead to zombie SPAWN flows

Links to More Info: BT1078357

Component: Local Traffic Manager

Symptoms:
Due to the presence of a specific set of events in the iRule, the Bloom filter may cause TCL to execute an event that is not implemented in the iRule.

In the execution of a sequence of events, when TCL attempts to execute the non-existing event, it follows a path which in turn makes SPAWN flow to become a zombie.

Conditions:
-- http2, client-ssl, optimised-caching filters on the virtual server
-- HTTP::respond iRule with LB_FAILED event and set of iRules like HTTP_REQUEST, HTTP_RESPONSE, CLIENTSSL_HANDSHAKE, CACHE_RESPONSE, ASM_REQUEST_BLOCKING

1077789-4 : System might become unresponsive after upgrading.&start;

Links to More Info: BT1077789

Component: TMOS

Symptoms:
After upgrading, the system encounters numerous issues:

-- Memory exhaustion (RAM plus swap) with no particular process consuming excessive memory.
-- High CPU usage with most cycles going to I/O wait.
-- System is unresponsive, difficult to log in, slow to accept commands.
-- Provisioning is incomplete; there is a small amount of memory amount assigned to 'host' category.

Conditions:
-- The configuration loads in the previous release, but does not load successfully on the first boot into the release you are upgrading to.
-- Device is upgraded and the configuration is rolled forward.
-- There may be other conditions preventing the configuration from loading successfully after an upgrade.

Exact conditions that trigger this issue are unknown and could be varied. In the environment in which it occurs, a datagroup is deleted, but an iRule still references it.

Impact:
-- System down, too busy to process traffic.
-- Difficulty logging in over SSH might require serial console access.

Workaround:
Reboot to an unaffected, pre-upgrade volume.

-- If the system is responsive enough, use 'tmsh reboot volume <N>' or switchboot to select an unaffected volume.

-- If the system is completely unresponsive, physically powercycle a physical appliance or reboot a BIG-IP Virtual Edition (VE) from an applicable management panel, and then select an unaffected volume from the GRUB menu manually.

Note: This requires that you have console access, or even physical access to the BIG-IP device if you are unable to SSH in to the unit. On a physical device, a non-responsive system might require that you flip the power switch.

1077405-2 : Ephemeral pool members may not be created with autopopulate enabled.

Links to More Info: BT1077405

Component: TMOS

Symptoms:
Ephemeral pool members might not be added to a pool with an FQDN pool member "autopopulate enabled".

When this issue occurs:

-- Some or all of the expected Ephemeral Pool Members will not be created for the affected pool.

-- A message will be logged in the LTM log similar to the following:

err mcpd[####]: 01070734:3: Configuration error: Cannot enable pool member to autopopulate: node (/Common/_auto_<IP address>) has autopopulate set to disabled.

(Note that the node name here is an Ephemeral Node.)

Also note that if you attempt to create an FQDN Pool Member with autopopulate enabled while the corresponding FQDN Node has autopopulate disabled, you will see a similar error message:
01070734:3: Configuration error: Cannot enable pool member to autopopulate: node (/Common/fred) has autopopulate set to disabled.

Conditions:
This issue can occur under the following conditions:

-- Two or more FQDN Nodes have FQDN names that resolve to the same IP address(es).
  -- That is, some Ephemeral Nodes have addresses resolved by more than one FQDN name defined in FQDN Nodes.

-- At least one of these FQDN Nodes has "autopopulate enabled."

-- At least one of these FQDN Nodes does not have "autopopulate enabled."
  -- That is, autopopulate is disabled for one or more of these FQDN Nodes.

-- The FQDN Pool Member(s) in the affected pool(s) has "autopopulate enabled."

Impact:
The affected LTM pool(s) are not populated with expected (or any) ephemeral pool members.

Workaround:
To allow some LTM pools to use FQDN pool members with autopopulate enabled (allowing multiple ephemeral pool members to be created) while other LTM pools use FQDN pool members with autopopulate (allowing only one ephemeral pool member to be created), configure the following:

-- Create all FQDN Nodes with FQDN names that might resolve to a common/overlapping set of IP addresses with "autopopulate enabled".

-- Create FQDN Pool Members with autopopulate enabled or disabled depending on the desired membership for each pool.

1076921-1 : Log hostname should be consistent when it contains ' . '

Links to More Info: BT1076921

Component: TMOS

Symptoms:
Messages that are logged to journald use the configured hostname, while sylog-ng uses the hostname (machine name) and truncates it starting at the first '.' (period). This results in hostnames being inconsistent when it contains '.'; e.g., 'my.hostname' is logged as 'my' by syslog-ng, and 'my.hostname' by journald. This can make it difficult for log analysis tools to work with the log files.

Conditions:
-- Hostname contains a period.
-- Viewing log files emitted from journald and from syslog-ng.

Impact:
The full hostname is logged for system logs while logs that go directly to syslog-ng use a truncated hostname.

Workaround:
N/A

1073965-1 : IPsec IKEv2 tunnel may report huge "life" for IKE SA.

Links to More Info: BT1073965

Component: TMOS

Symptoms:
The output of "tmsh show net ipsec ike-sa" will report an impossibly high life value.

tmsh show net ipsec ike-sa | grep Life
  Life/Active Time: 18446744073709551028/6 seconds

Decrypting the IKE AUTH payload will show something similar to this:

        Decrypted Data (160 bytes)
            Contained Data (156 bytes)
                Payload: Identification - Responder (36)
                Payload: Authentication (39)
                Payload: Security Association (33)
                Payload: Traffic Selector - Initiator (44) # 1
                Payload: Traffic Selector - Responder (45) # 1
                Payload: Notify (41) - AUTH_LIFETIME
                    Next payload: NONE / No Next Payload (0)
                    0... .... = Critical Bit: Not Critical
                    .000 0000 = Reserved: 0x00
                    Payload length: 12
                    Protocol ID: RESERVED (0)
                    SPI Size: 0
                    Notify Message Type: AUTH_LIFETIME (16403)
                    Notification DATA: fffffdb4
                    Authentication Lifetime: 4294966708 seconds (1193046 hour(s) 18 minute(s) 28 second(s))
            Padding (3 bytes)
            Pad Length: 3

Conditions:
-- IKEv2
-- BIG-IP is initiator
-- Responder sends very high value (close to maximum possible in 4 byte payload) for Authentication Lifetime in IKE AUTH phase.

Impact:
In general this is not a problem unless the DPD/liveness is disabled and the remote peer silently goes away. Under perfect conditions, the remote peer would send a delete for the IKE SA to the BIG-IP and cause the BIG-IP (as initiator) to start a new IKE SA as required.

Workaround:
Ensure the remote peer sends a more reasonable value such as 1 day for the IKE AUTH lifetime.

Strongswan devices have been observed to send a very high value when configured with an unreasonably low "ikelifetime" (in the order of a few minutes).

1073429-1 : Auth partition definition is incorrectly synchronized to peer and then altered.

Links to More Info: BT1073429

Component: TMOS

Symptoms:
An auth partition definition with "device-group none" and "traffic-group none" is incorrectly synchronized to other devices during a full config-sync.

Specifically, the partition is incorrectly synchronized to all other devices that belong to the device-group to which the /Common partition is associated.

Furthermore, the receiving devices incorrectly alter the definition of said partition, in such a way that the definition no longer specifies "device-group none" and "traffic-group none". Instead, this partition will now have inheritance (from the root folder) enabled for both the device-group and traffic-group properties.

Conditions:
Creating an auth partition (for example /Example) which specifies "device-group none" and "traffic-group none" on redundant units, and then issuing a full config sync to the device-group.

Note that even if your device-group is configured to perform incremental syncs, sometimes performing a full sync between devices is a natural and unavoidable event.

Impact:
The definition of an auth partition that was meant to remain local to a given BIG-IP system is incorrectly synchronized to peer devices. Additionally, its device-group and traffic-group properties are altered so that inheritance from the root folder is now enabled.

Initially, this has no other negative consequences, as the configuration objects contained in the "local partition" of the source device are not synchronized. However, a further config sync from the initial receiving device to the initial source device will overwrite the device-group and traffic-group properties there. Once in this state, the unit that contains configuration objects in the "local partition" will synchronize them to the peers during the next config-sync. This can impact the application traffic based on the objects synchronized.

Workaround:
You cannot work around this issue.

However, you may be able to achieve your goal of having a repository for local-only objects by creating a subfolder to the /Common partition rather than creating a new partition.

For example:

tmsh create sys folder /Common/local device-group none traffic-group none

1072173-1 : The BIG-IP system incorrectly presents legacy ways of defining mirroring properties

Links to More Info: BT1072173

Component: TMOS

Symptoms:
The 'sys state-mirroring' section in tmsh, as well as the following db keys, are deprecated and should not be used to define the mirroring properties of a device:

sys db statemirror.ipaddr
sys db statemirror.peeripaddr
sys db statemirror.secondary.ipaddr
sys db statemirror.secondary.peeripaddr
sys db statemirror.state

If you wish to configure the mirroring properties of a BIG-IP device, please use the 'cm' section in tmsh, or use the configuration utility under Device Management > Devices.

Each device only needs to set its own properties, for instance:

tmsh modify cm device bigip-ntr-a.local mirror-ip 10.0.0.60
tmsh modify cm device bigip-ntr-a.local mirror-secondary-ip 192.168.1.60

Conditions:

1071485-3 : For IP based bypass, Response Analytics sends RST.

Links to More Info: BT1071485

Component: Access Policy Manager

Symptoms:
When SSL takes a dynamic bypass action (IP based bypass decision), the Per-Request Policy agents skip execution when necessary. That is, Category Lookup exits early due to no data because of the early bypass. The same check is not present in Response Analytics and URL Filter agents so that they don't take the error path due to not seeing Category Lookup data.

Conditions:
IP based bypass (in client SSL profile) with Response Analytics or URL Filtering in the Per-Request Policy.

Impact:
Category Lookup skips execution due to IP based bypass and thus Response Analytics and URL Filtering do not have the necessary data, so they take an internal error path. This will cause an RST.

Workaround:
Do not add Response Analytics or URL Filtering agents to paths that you know will not have appropriate Category Lookup data due to bypass.


1071385-3 : SSL session resumption using session tickets is incorrectly logging handshake failure messages

Links to More Info: BT1071385

Component: Local Traffic Manager

Symptoms:

Conditions:
-- Enable session-ticket in SSL profile.
-- Client establishes connection with session resumption option

Impact:
Inaccurate information in log.

Workaround:
None


1071301-1 : GTM server does not get updated even when the virtual server status changes.

Links to More Info: BT1071301

Component: Global Traffic Manager (DNS)

Symptoms:
GTM Server is in an Unknown state even though the single virtual server is green.

Conditions:
-- Three-member sync group.
-- Create a large number of virtual servers.
-- Virtual servers are disabled and enabled.

Impact:
The server status does not reflect the virtual server status, and there is no obvious way to recover.

Workaround:
N/A


1071233-1 : GTM Pool Members may not be updated accurately when multiple identical database monitors are configured

Links to More Info: BT1071233

Component: Global Traffic Manager (DNS)

Symptoms:
When two or more GTM database monitors (MSSQL, MySQL, PostgreSQL, and Oracle) with identical 'send' and 'recv' strings are configured and applied to different GTM pools (with at least one pool member in each), the monitor status of some GTM pool members may not be updated accurately.

Other parameters of the affected monitors that differ (such as 'recv row' or 'recv column' indicating where the specified 'recv' string should be found in the result set) may cause GTM pool members using one of the affected monitors to connect to the same database to be marked UP, while GTM pool members using another affected monitor may be marked DOWN.

As a result of this issue, GTM pool members that should be marked UP or DOWN by the configured GTM monitor may instead be marked according to another affected monitor's configuration, resulting in the affected GTM pool members being intermittently marked with an incorrect state.

After the next monitor ping interval, affected GTM pool members members may be marked with the correct state.

Conditions:
This may occur when multiple GTM database monitors (MSSQL, MySQL, PostgreSQL, and Oracle) are configured with identical 'send' and 'recv' parameters, and applied to different pools/members which share the same IP address and Port values.

For example:
gtm monitor mysql mysql_monitor1 {
...
    recv none
    send "select version();"
...
}
gtm monitor mysql mysql_monitor2 {
...
    recv none
    send "select version();"
...
}

Impact:
Monitored GTM pool members using a database monitor (MSSQL, MySQL, PostgreSQL, and Oracle) randomly go offline/online.

Workaround:
To avoid this issue, configure each GTM database monitor with values that make the combined parameters unique by changing either the 'send' or the 'recv' parameters, or both.

For example:
gtm monitor mysql mysql_monitor1 {
...
    recv none
    send "select version();"
...
}
gtm monitor mysql mysql_monitor2 {
...
    recv 5.7
    send "select version();"
...
}


1070957-1 : Database monitor log file backups cannot be rotated normally.

Links to More Info: BT1070957

Component: Local Traffic Manager

Symptoms:
Debug log files used by the BIG-IP database monitor daemon (DBDaemon) do not exhibit the log-rotation behavior of other BIG-IP log files.
- The active DBDaemon log file is /var/log/DBDaemon-0.log
- DBDaemon log file size is limited to approximately 5MB. DBDaemon log files are backed up/rotated upon reaching this size.
- Exactly 9 (nine) DBDaemon log file backups are retained (/var/log/DBDaemon-0.log.[1-9])
- DBDaemon log file backups are not compressed.
- DBDaemon log file backup/rotation behavior is not user-configurable.

Conditions:
This issue applies when using BIG-IP database monitors:
-- mssql
-- mysql
-- oracle
-- postrgresql

Impact:
-- DBDaemon log file backups may consume more space under /var/log than desired.
-- When troubleshooting database monitor issues, DBDaemon log file rotation may occur so rapidly that older DBDaemon events may be lost, limiting the ability to capture meaningful diagnostic data.

Workaround:
It may be possible to work around this issue by periodically archiving DBDaemon log files, such as in a script with the following core functionality:
pushd /var/log;tar -czf DBDaemon_$(date +%Y%m%d%H%M).tgz DBDaemon-0.log*;popd

1070033-2 : Virtual server may not fully enter hardware SYN Cookie mode.

Links to More Info: BT1070033

Component: Advanced Firewall Manager

Symptoms:
The SYN Cookies Status of a virtual server shows 'full-hardware', but the 'Total Software' counter of software SYN Cookies continues to increment together with the 'Total Hardware' SYN Cookie counter during a SYN flood attack.

Conditions:
On platforms with multiple HSB modules each TMM connects to only one of the modules. This depends on platform, BIG-IP version and selected turboflex profile.

The simplest way to check is to look at the epva_flowstat tmstat table. If there is only one row per TMM and there are more than one distinct mod_id numbers, then the device is affected. For example:

$ tmctl -s tmm,mod_id,pdenum,slot_id epva_flowstat
tmm mod_id pdenum slot_id
--- ------ ------ -------
  0 1 0 0
  1 1 8 0
  2 2 0 0
  3 2 8 0

Impact:
A portion of the SYN flood attack is handled in software, which might have some performance impact.

Workaround:
N/A

1069113-1 : ASM process watchdog should be less aggressive.

Links to More Info: BT1069113

Component: Application Security Manager

Symptoms:
During standard operation a process is expected to exit and be restarted once it has exceeded a certain memory limit. As a failsafe, the watchdog forcefully kills the process if it exceeds a higher threshold. But if the handler was running close to the memory limit before a resource-intensive event like a full sync load, this operation could push it over both limits.

Conditions:
An ASM Config handler is running close to the memory limit before a resource intensive event, like a full sync load.

Impact:
A process may be killed in the middle of a data-integrity sensitive action, like a device-group sync, which can leave the system in a corrupt state.

Workaround:
Modify the memory limits in nwd.cfg to raise it by 100MB.

1063865-7 : Blade remains in an INOPERATIVE state after being moved to new chassis.

Links to More Info: BT1063865

Component: Local Traffic Manager

Symptoms:
When moving a blade to a new chassis, it can remain in an INOPERATIVE state upon startup. The following errors can be found in /var/log/ltm:

slot2 notice mcpd[7042]: 01071029:5: Master Key not present.
slot2 err csyncd[8163]: 013b0004:3: Unable to subscribe to mcpd, disconnecting...

Conditions:
- Multi-bladed BIG-IP systems
- Move a blade from one chassis to an open slot in the other chassis

Impact:
The moved blade will not properly sync up with the rest of the system, and remain INOPERATIVE.

Workaround:
This occurs due to the master key not being propagated to the moved blade. You can manually circumvent this by doing the following (this assumes slot 1 is primary and slot 2 has the moved blade):

Back up the master keys first (optional):
1. On the primary slot:
cp /config/bigip/kstore/master /var/tmp/master_slot1
2. On the moved slot:
cp /config/bigip/kstore/master /var/tmp/master_slot2

Copy the master key to the moved slot:

1062953-1 : Unable to save configuration via tmsh or the GUI.

Links to More Info: BT1062953

Component: TMOS

Symptoms:
If there are hundreds of partitions and changes to the configuration are made via the GUI, the configuration save can hang. When the configuration save hangs, all subsequent configuration saves will not complete.

Conditions:
-- Hundreds of partitions with objects contained in them.
-- Changing config via the GUI.

1062901-1 : The 'trap-source' and 'network' SNMP properties are ineffective, and SNMP traps may be sent from an unintended interface.

Links to More Info: BT1062901

Component: TMOS

Symptoms:
The BIG-IP system sends SNMP traps from an unintended interface (likely a TMM VLAN instead of the management port).

Conditions:
This issue occurs when the configuration:

- Includes a 'trap-source' property which matches the BIG-IP system's management IP address.

- Includes a SNMP trap destination which specifies 'mgmt' as the 'network' property.

- Includes routes to the aforementioned SNMP trap destination via both tmm and the management port (and the routes are such that the tmm one wins).

Impact:
Outgoing snmp traps fail to bind to the management IP address and to leave from the management port. Instead, they will bind to a self-ip matching TMM's route to the destination and leave from a TMM VLAN.

This can cause issues (or not work at all) depending on the configuration of the host system meant to receive the traps and/or of the surrounding network devices.

Workaround:
N/A


1062857-3 : Non-tmm source logs stop populating after a system time change.

1060833-2 : After handling a large number of connections with firewall rules that log or report translation fields or server side statistics, TMM may crash.

Links to More Info: BT1060833

Component: Advanced Firewall Manager

Symptoms:
TMM crashes.

The 'virt_cnt' column in the tmctl 'string_cache_stat' table continues to grow over time, and diverges significantly from the 'phys_cnt' column.

Conditions:
-- Enforced AFM firewall policies configured in multiple contexts (global, route domain, virtual server)

-- Large number of connections that matches rules in multiple contexts

-- AFM configured in at least one of the following ways:

--+ Stats collection enabled and collecting server-side stats enabled. Stats collection is enabled by default. Collecting server-side statistics ("security analytics settings acl-rules { collect-server-side-stats }") is not enabled by default.
--+ ACL logging enabled, and the logging of translation fields enabled.

Impact:
Traffic is disrupted while TMM restarts.

Workaround:
Disable logging and reporting of server-side information in AFM firewall ACLs.

After making these changes, it may be necessary to restart TMM once.


1060769-1 : The /mgmt/tm/sys/performance/all-stats and /mgmt/tm/sys/performance/throughput iControl REST endpoints cannot be successfully parsed by common JSON libraries.

Links to More Info: BT1060769

Component: TMOS

Symptoms:
Because of identically-named key/value pairs in the "entries" object returned by the /mgmt/tm/sys/performance/all-stats and /mgmt/tm/sys/performance/throughput iControl REST endpoints, the output of these endpoints cannot be successfully parsed by common JSON-parsing libraries.

Only the key/value pair appearing last for a given name is returned by common JSON-parsing libraries.

As a result, the In/Out/Service sections of the output, which should show both Throughput(bit) and Throughput(packets) only shows Throughput(packets).

Conditions:
Querying the /mgmt/tm/sys/performance/all-stats or /mgmt/tm/sys/performance/throughput iControl REST endpoints.

Impact:
Common JSON-parsing libraries are unable to extract all of the information contained in the JSON blob (only a subset of the information is returned).

Workaround:
If possible, use the TMSH utility from the CLI of the BIG-IP system to display the complete information.

1058645-2 : ipsecalg blocks Sophos ISAKMP negotiation during tunnel setup.

Links to More Info: BT1058645

Component: Advanced Firewall Manager

Symptoms:
Sophos IPsec clients cannot connect to a Sophos firewall when ipsecalg is configured on the forwarding virtual server.

The Sophos client initially attempts to start the tunnel using aggressive mode. The Sophos firewall does not support remote users attempting aggressive mode and responds with Notify Message Type INVALID-PAYLOAD-TYPE. The tunnel setup cannot proceed correctly after that point.

Conditions:
-- Sophos client is installed on remote user devices.
-- Sophos firewall is the remote endpoint in the IPsec tunnel.

Note: The Sophos client and firewall combination is the only known failing use-case.

Impact:
Sophos clients cannot start an IPsec tunnel.

Workaround:
The Sophos client cannot be configured to use main mode instead of starting with aggressive mode. The Sophos firewall does not support aggressive mode for remote user IPsec tunnels.

Therefore, create an iRule and add the iRule to the ipsecalg virtual server. The iRule simply contains this:

when SERVER_DATA {
# Only execute on first server side packet of conflow.
event disable

if { [UDP::payload length] < 40 } { return; }
binary scan [UDP::payload] x8x8cH2cx9x10S payload_type ver exch_type noti_type

# Depending on throughput, the amount of logging here may be problematic
#log local0. "payload_type : $payload_type"
#log local0. "ver : $ver"
#log local0. "exch_type : $exch_type"
#log local0. "noti_type : $noti_type"

if { $payload_type == 11 && $ver == 10 && $exch_type == 5 && $noti_type == 1 } {
log local0. "Closing ipsecalg connection"
after 1 { reject }
}

1057557-5 : Exported policy has greater-than sign '>' not escaped to '&gt;' with response_html_code tag.

Links to More Info: BT1057557

Component: Application Security Manager

Symptoms:
The greater-than sign '>' is not escaped/converted to '&gt;' with response_html_code tag.

Having an un-escaped greater-than sign can cause issues when re-importing the policy, if the greater-than sign appears in a specific sequence, ']]>'. In other words, if the greater-than sign does not appear in the specific sequence, you can successfully re-import the policy without problem.

The specific sequence can be possible with a custom response page configuration. If you modify the custom response page in the way it has a sequence of characters ']]>', as the greater-than sing won't be escaped due to this bug, the exported policy has the sequence of characters ']]>' as is. Note: what it should be is ']]&gt;'

']]>' in xml is CDATA End delimiter and not allowed. The exported policy causes parser error and can not be re-imported.

Conditions:
This issue occurs if you modify the default custom response page where this specific character sequence is observed ']]>'.

Impact:
The exported policy cannot be re-imported.

Workaround:
This workaround forces the greater-than sing to be escaped to '&gt;' so that that policy can be re-imported without problem.

1057501-4 : Expired DST Root CA X3 resulting in http agent request failing.

Links to More Info: BT1057501

Component: TMOS

Symptoms:
When the DST Root CA X3 is expired, any HTTP agent request fails with the error:

err tmm2[19302]: Rule /Common/my_rule <HTTP_REQUEST>: Client - <address>, failure :proxyInterstitialPage: FetchError: request to <url> failed, reason: certificate has expired.

Conditions:
The DST Root CA X3 certificate is expired, see
https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/.

Impact:
ILX plugins that reply on outbound HTTP client/agent requests to remote servers fail.

Workaround:
Create a /var/tmp/isrgrootx1.pem with contents of https://letsencrypt.org/certs/isrgrootx1.pem.txt.

The Node.js script:
# cat /var/tmp/CustomCA-2.js
var fs = require('fs');
var https = require('https');
var options = {
    hostname: 'letsencrypt.org',
    port: 443,
    path: '/',
    method: 'GET',
    ca: fs.readFileSync('/var/tmp/isrgrootx1.pem') <<<<<<<<<<<<<<< incorporated CA thus bypassing the CA embedded in the EOL version of Node.js
};
var req = https.request(options, function(res) {
    res.on('data', function(data) {
        console.log("PASS");
    });
});
req.end();

1056941-2 : HTTPS monitor continues using cached TLS version after receiving fatal alert.

Links to More Info: BT1056941

Component: Local Traffic Manager

Symptoms:
After an HTTPS monitor completes successfully, the TLS version is cached and used for subsequent monitor probes.
If the back end server TLS version changes between monitor polls and no longer allows the cached TLS version, the back end server correctly sends a fatal alert to the BIG-IP in response to the no longer allowed TLS version.
The BIG-IP will continue to use the cached, now prohibited, version in all subsequent probes resulting in a false down resource until the cached information is cleared on the BIG-IP.

Conditions:
ClientSSL profile is changed on backend BIG-IP device's virtual server,

Impact:
BIG-IP continues to send prohibited TLS version and reports the member as down.

Workaround:
-- Delete and re-add pool member.
-- Change HTTPS monitor to any other monitor (including another HTTPS monitor) and then back.
-- Restart bigd with "bigstart restart bigd" - Note that this impacts all monitoring on the BIG-IP.
-- Restart BIG-IP - Note that this impacts all traffic on the BIG-IP.


1055077-1 : Modifying the datacenter does not check GTM server configuration for prober-pool.

Links to More Info: BT1055077

Component: Global Traffic Manager (DNS)

Symptoms:
If GTM is in a bad configuration state, the reload can fail with an error similar to this:

01071b63:3: The prober fallback value for server /Common/server1 cannot be the same as the inherited prober preference value.
Unexpected Error: Validating configuration process failed.

or

01071b62:3: The prober preference value for server /Common/server2 cannot be the same as the inherited prober fallback value.
Unexpected Error: Validating configuration process failed.

Conditions:
1. GSLB server has a prober-pool and inherits the datacenter selected for prober preference or prober fallback (it does not matter which prober configuration has which value).
2. GSLB datacenter is modified such that the prober configuration inherited by the constituent GSLB server is changed from a non-pool method to prober-pool.

This results in the GSLB server having a prober-pool probe configuration manually configured and another prober-pool probe configuration inherited from the GSLB datacenter.

Impact:
Two prober-pool configurations for a GSLB server is a prohibited state. Once this state is reached, any action that tries to validate the configuration (like a configuration load) will fail. This can cause the BIG-IP to fail to load configuration or cause a UCS restore to fail.

Workaround:
Review the configured and inherited prober configuration state of all GSLB servers whose parent GSLB datacenter has a prober-pool configured for it's prober preference or prober fallback. If any GSLB servers are affected, change their prober configuration so that only a single prober-pool configuration exists; or, you can change the parent GSLB server to no longer use the prober-pool method.

Workaround:
Disable the 'pager' option in 'cli preference' config for the affected user.


1054497-1 : Tmsh command "show sys fpga" does not report firmware for all blades.

Links to More Info: BT1054497

Component: TMOS

Symptoms:
After upgrading or forcing a reload of the configuration, the tmsh command "show sys fpga" does not report the firmware for all blades.

Conditions:
- Mutli-blade VIPRION or vCMP guest.
- Upgrade or forced reload of the configuration

bigstart restart chmand


1053741-4 : Bigd may exit and restart abnormally without logging a reason

Links to More Info: BT1053741

Component: Local Traffic Manager

Symptoms:
Certain fatal errors may cause the bigd daemon to exit abnormally and restart to recover.
For many such fatal errors, bigd logs a message in the LTM log (/var/log/ltm) indicating the fatal error that occurred.
For some causes, no message is logged to indicate what error occurred to cause big to exit abnormally and restart

Conditions:
This may occur when bigd encounters a fatal error when monitoring LTM pool members, particularly (although not exclusively) when using In-TMM monitor functionality (sys db bigd.tmm = enable).

Impact:
It may be difficult to diagnose the reason that caused bigd to exit abnormally and restart.

Workaround:
To enable logging of all fatal errors that cause bigd to exit abnormally and restart, enable bigd debug logging:

tmsh modify sys db bigd.debug value enable

With bigd debug logging enabled, bigd messages (including such fatal errors) will be logged to /var/log/bigdlog


1053605-2 : When you use NAT, the iQuery status displays 'BIGIP' instead of 'BIGIP-DNS'.

Links to More Info: BT1053605

Component: Global Traffic Manager (DNS)

Symptoms:
Use the 'show gtm iquery' command. The 'Server Type' may show as "BIGIP" rather than "BIGIP-DNS", even though DNS is provisioned on that device.


   # tmsh show gtm iquery
   ----------------------------------------
   Gtm::IQuery: 10.0.0.1
   ----------------------------------------
   Server GTM1
   Server Type BIG-IP <--
   ...
   ...
   ...


Note: Other BIG-IP DNS devices in the same sync group will correctly show the status as 'BIGIP-DNS'.

Conditions:
This occurs in the following conditions:

 - The gtm server has both an address and a translation defined.
 - The BIG-IP running the command is the same device being viewed (that is, it is showing its own status).
 

For example:

   gtm server GTM1 {
      devices {
         GTM1 {
            address { 10.0.0.1 { translation 192.168.1.1 } }
         }
      }
      ...
   }

Impact:
This is purely cosmetic, and does not affect the operation of the iQuery protocol.

Workaround:

1053149-1 : A FastL4 TCP connection which is yet to fully establish fails to update its internal SEQ space when a new SYN is received.

Links to More Info: BT1053149

Component: Local Traffic Manager

Symptoms:
Depending on the software version running on the BIG-IP system, this issue can manifest in one of two ways:

- Versions with the fix for ID1008077 will fail to forward the client's final ACK (from the TCP 3-way handshake) to the server. Eventually, once the TCP handshake timeout expires, the BIG-IP system will reset both sides of the connection.

- Versions without the fix for ID1008077 will forward the traffic correctly, but will not advance the internal FastL4 state for the connection. Given enough traffic for the same 4-tuple, the connection may never expire. Traffic for subsequent connections will appear to be forwarded correctly, but no load-balancing will occur due to the original connection not having expired yet.

Conditions:
A FastL4 TCP connection not completing the TCP handshake correctly, and the client retrying with a new (different SEQ number) SYN.

Impact:
Traffic failures (intended as either connections failing to establish, or improper load-balancing occurring).


1053037-7 : MCP error on loading a UCS archive with a global flow eviction policy

Links to More Info: BT1053037

Component: TMOS

Symptoms:
Attempting to load a UCS archive with a global flow eviction policy results in an error like the following.

loaddb[3609]: 01080023:3: Error return while getting reply from mcpd: 0x1070911, 01070911:3: The requested flow_eviction_policy object (/Common/otters) does not exist for global_flow_eviction_policy in ltm (/Common/ltm)
Error 0x1070911 occurred: 01070911:3: The requested flow_eviction_policy object (/Common/otters) does not exist for global_flow_eviction_policy in ltm (/Common/ltm)

Despite this error, restoring the UCS archive continues on, and may succeed.

Conditions:
-- Loading a UCS archive with a non-default global-flow-eviction-policy configured.
-- The existing configuration on the BIG-IP system does not define the same eviction policy.

Impact:
The above mentioned error message is printed to the logs.
It should be safe to ignore the error if the UCS otherwise loads successfully.

Workaround:
Ignore the error message.

Component: Local Traffic Manager

Symptoms:
DHCP DISCOVER packets are received, load balanced to the back end DHCP server, a DHCP OFFER reply is received from the server to BIG-IP, but this packet is dropped.

Conditions:
A BIG-IP system is between the DHCP client and DHCP server.

Impact:
DHCP OFFER is never passed on to the client, and as such, the client keeps sending DHCP DISCOVER packets, which are all dropped the same way.


1051125-1 : GTM marks virtual servers offline even when LTM virtual servers are available.

Links to More Info: BT1051125

Component: Global Traffic Manager (DNS)

Conditions:
-- Sync group of two GTM devices with a large number of virtual servers (2k).

1050661-1 : Warning message with UDP on DOH server side.

Links to More Info: BT1050661

Component: Global Traffic Manager (DNS)

Symptoms:
DOH with server side flow using UDP results in a DoH server that is unable to deliver DNS replies larger than 4096 bytes to the DoH client (a truncated (TC) response will be sent instead).

Conditions:
1. A DNS profile that has all the internal DNS resolution features turned off (gslb, cache, dns-express, local-bind), so that DNS requests are load balanced to the pool
   tmsh create ltm profile dns dns-pool-only enable-dns-express no enable-dnssec no enable-gtm no process-rd no use-local-bind no

2. A pool pointing to a DNS server
   tmsh create ltm pool dns-pool-only members add {x.x.x.x:53}

3. An LTM virtual server that has TCP on the clientside (DoH server) and UDP on the server-side flow.
   tmsh create ltm virtual vs-doh-server destination x.x.x.x:443 ip-protocol tcp profiles add {doh-server tcp { context clientside } udp_gtm_dns { context serverside } http2 http clientssl-secure dns-pool-only }

Trigger by sending a DoH request to the virtual-server for a DNS resource record that is larger than 4096 bytes. A truncated response will be returned to the DoH client. Since the client is already using TCP (and HTTPS) to send the query, it can not retry the query using TCP like a traditional client could do.

Impact:
DNS responses with the TC (truncated) bit are received via the BIG-IP DoH virtual server.

Note that this is correct behavior, per RFC8484, for this configuration.

Workaround:
1. Use TCP on the server-side flow (this is the default if you don't specifically set the serverside to use UDP). The use of TCP will mean that each DNS request requires a TCP 3WHS and 4-way close.

(or)

2. Instead of configuring DNS servers as pool members, configure them as forward-zone nameservers for dns-cache, and enable dns cache in the DNS profile.

(or)

3. Ensure that the configuration is only used when you can be certain that no replies larger than 4096 bytes will ever be provided by the DNS server (pool member)


1050457-1 : The "Permitted Versions" field of "tmsh show sys license" only shows on first boot

Links to More Info: BT1050457

Component: TMOS

Symptoms:

Component: Device Management

Symptoms:
Files that restjavad makes available for download (such as UCS files in /var/local/ucs) can be held open indefinitely if a requesting client (such as a BIG-IQ which is out of disk space) does not complete the download.
Since these files remain open, you may see low disk space even after deleting the associated files, and you may see items listed with '(deleted)' in lsof output.

Additionally, on a software version with ID767613 fix, you may see restjavad NullPointerException errors on /var/log/restjavad.*.log.

Conditions:
1) a hardware platform is configured to use RAID for redundancy
2) duplicate RAID array declarations are introduced into /etc/mdadm.conf
3) a hotfix installation is performed to one of the RAID volumes

Impact:
Impossible to boot into the volume of the new installation, it is necessary to physically reboot the device and revert to a previously working volume to rectify the problem.

Workaround:
Instead of installing the hotfix directly, first install the plain base version on which the hotfix is based and boot into it - this will resolve the problem with the duplicate entries in /etc/mdadm.conf.
Then install the hotfix as normal.

1045277-4 : The /var partition may become 100% full requiring manual intervention to clear space

Links to More Info: BT1045277

Component: TMOS

Symptoms:
The /var partition might become completely full on the disk due to files being written to /var/config/rest. This condition may be accompanied by console error messages similar to the following:
011d0004:3: Disk partition /var (slot #) has only 0% free on secondary blade.

Additionally, there may be periodic restjavad and bigd daemons restarts related to disk space exhaustion.

Conditions:
Process traffic while DoS Dashboard is open

Impact:
The partition housing /var/config/rest may become 100% full, impacting future disk IO to the partition.

Workaround:
Important: This workaround is temporary, and may need to be periodically performed either manually or from a script.

Impact of Workaround: While these steps are performed, the BIG-IP REST API will be temporarily inaccessible, and higher disk IO may be seen.

Run the following commands, in sequence:

bigstart stop restjavad
rm -rf /var/config/rest/storage*.zip
rm -rf /var/config/rest/*.tmp
bigstart start restjavad

Manual application of these workaround steps clears the 100% utilized space condition and allows the partition to resume normal operation.

1040277-4 : Syslog-ng issue may cause logging to stop and possible reboot of a system

Links to More Info: BT1040277

Component: TMOS

Symptoms:
A syslog-ng issue with remote logging to an invalid remote syslog server may lead to logging via syslog-ng to stop.

For software version 13.1 only it may lead to BIG-IP unexpectedly rebooting due to host watchdog timeout, typically within hours to day or two after syslog-ng gets hung up.


The cessation of logging happens at the time of the last 'Syslog connection broken' in /var/log/messages before reboot.
That message will appear without a preceding 'Syslog connection established' just before it with same timestamp.

At this time syslog-ng typically spins, using near 100% CPU.

Conditions:
Invalid syslog-ng server configuration or broken connection from BIG-IP toward configured syslog-ng remote server.

A server is configured as a remote syslog destination on the BIG-IP, but it or an intervening system responds to stream of log messages by breaking connection eg by sending ICMP port unreachable to BIG-IP.

Syslog-ng will note the connection attempt and that it has broken usually in the same second, and do so every 60s when it retries.
There may be many of these log pairs, repeating every minute in /var/log/messages, such as:

  Nov 25 03:14:01 localhost.localdomain notice syslog-ng[12452]: Syslog connection established; fd='14', server='AF_INET(192.168.1.1:514)', local='AF_INET(0.0.0.0:0)'
  Nov 25 03:14:01 localhost.localdomain notice syslog-ng[12452]: Syslog connection broken; fd='14', server='AF_INET(192.168.1.1:514)', time_reopen='60'

The final log will of a broken connection only, usually one minute after the last established/broken pair in the very rare event that syslog-ng hangs.

  Nov 25 03:15:01 localhost.localdomain notice syslog-ng[12452]: Syslog connection broken; fd='14', server='AF_INET(192.168.1.1:514)', time_reopen='60'

Impact:
Very rarely syslog-ng hangs in a non-functional state. Sometimes, this may lead to an unexpected reboot of BIG-IP. Loss of logs before restart and traffic disrupted while BIG-IP restarts.

Workaround:
Ensure syslog-ng server configuration is valid, and that the server is reachable. If a remote server is not reachable remove it from the BIG-IP syslog configuration.

1037153-1 : iRule "log" command to remote destinations may cause TMM to leak memory

Links to More Info: BT1037153

Component: Local Traffic Manager

Symptoms:
TMM leaks memory in the errdefs component.

TMM may leak memory in the xdata and xhead components if the system does not have routes to the specified syslog servers.

Conditions:
-- iRule that uses "log" to target a remote destination, e.g.: "log 192.0.2.1 'log message'"

Impact:
TMM leaks memory.

Eventually, TMM may disrupt legitimate connections as a result of memory pressure, or even crash and restart.

Workaround:
One of the following:

1. Log to local syslog, and configure syslog-ng to log to remote servers.

1036873-2 : Pre-shared key extension sometimes is not the last extension in ClientHello in TLS1.3

Links to More Info: BT1036873

Component: Local Traffic Manager

Symptoms:
Under some conditions, the BIG-IP's TLS 1.3 Client Hello sometimes does not have the pre-shared key extension as the last extension in the Client Hello. This is contrary to a requirement in the TLS 1.3 RFC, and causes servers to fail the connection.

A backend server may log a message such as:

SSL_do_handshake() failed (SSL: error:141B306E:SSL routines:tls_collect_extensions:bad extension)

Conditions:
-- Server SSL profile (BIG-IP operating as client) with TLS 1.3 enabled.
-- A Client Hello message size that falls between 256 and 512 bytes (without padding), which causes the BIG-IP to introduce a padding extension at the end of the Client Hello.

This issue can be seen via use of the "single-dh-use" or "session-tickets" options in the SSL profile.

Impact:
The TLS handshake fails.

Workaround:
Adjust the configuration of the Server SSL profile by either:

-- Disable Session Tickets
or
-- Disable the single-dh-use option

Conditions:
(a) Create a TCP monitor, then in a single transaction delete the TCP monitor + create an HTTP monitor with same name as the TCP monitor. Example below:

# tmsh create ltm monitor tcp <Name of the monitor>
# echo 'create cli transaction; delete ltm monitor tcp <Name of the monitor> ; create ltm monitor http <Name of the monitor>; submit cli transaction' | tmsh
# tmsh save sys config

This could also occur when reconfiguring an iApp, or changing a configuration via AS3.


(b) Login to the GUI and click on the monitor (GUI > Local Traffic > Monitors > (Monitor created)) you'll see "An error has occurred while trying to process your request"

Impact:
Unable to view monitor parameters in GUI.

Workaround:
Any one of the following workarounds help:
- do not use the same monitor name
- do not perform the delete+create actions on a single transaction
- save and load the configuration:
  tmsh save sys config && tmsh load sys config

1036097-4 : VLAN failsafe does not trigger on guest

Links to More Info: BT1036097

Component: TMOS

Symptoms:
VCMP guest VLAN failsafe does not trigger as expected.

Conditions:
-- VCMP host configured
-- VLAN failsafe enabled on a VLAN
-- One or more VCMP guests enabled that use that VLAN.
-- A trunk member of a trunk connected to the vCMP guest is flapping.

Impact:
Since the neighbor messages for the IPv6 link-local addresses continue to be successfully passed from host to guest upon a trunk member change, VLAN failsafe does not trigger even if the upstream switch goes down that's connected to the VLAN.

Workaround:
None


1036093-4 : Tmm sends out neighbor advertisements for the link local addresses even if IPv6 is disabled

Links to More Info: BT1036093

Component: Local Traffic Manager

Symptoms:
When a trunk member state changes and IPv6 is disabled, BIG-IP still sends neighbor advertisements for the link-local addresses on each VLAN

Conditions:
- IPv6 is disabled (ipv6.enabled=false)
- change in a trunk member state occurs

Impact:
Link-local addresses are still in the vaddr hash even after ipv6 is disabled.


1036057-1 : Add support for line folding in multipart parser.

Links to More Info: BT1036057

Component: Application Security Manager

Symptoms:
RFC 2616 allowed HTTP header field values to be extended over multiple lines by preceding each extra line with at least one space or horizontal tab. This was then deprecated by RFC 7230.

The multipart parser of ASM does not support the multiple line header, so these requests cause false positives.

Conditions:
Multiline header in multipart request

Impact:
False positives.

Workaround:
None


1036013-3 : BIG-IP systems may terminate connections prematurely when a TLS close-notify alert is received

Links to More Info: BT1036013

Symptoms:
When a backend server sends a TLS close-notify alert, BIG-IP may terminate the connection prematurely without forwarding the HTTP response.

Conditions:
ServerSSL receives a TLS Close-notify alert after a TLSv1.3 session is established.

Impact:
Server responses may be dropped.

Workaround:
Use TLSv1.2.


1036009-4 : Fix DPDK RSS configuration settings

Component: TMOS

Symptoms:
When using DPDK driver and multiqueue, only TCP traffic will get hashed and distributed between different TMMs

Conditions:
- DPDK driver is being used
- Multiqueue is enabled and in use

For a list of NICs that use dpdk see K17204: BIG-IP VE NIC adapters that support SR-IOV, available at https://support.f5.com/csp/article/K17204

Impact:
UDP traffic will get funneled to only a single TMM causing excess CPU usage on that TMM

Workaround:
Disable multiqueue


1035757-4 : iRulesLX restart leaves stale files in /var/tmstat/blade/tmplugin_ilx_*

Links to More Info: BT1035757

Component: Local Traffic Manager

Symptoms:
After restarting the ilx plugin, new tmplugin_ilx_rpc_* stat files are being created, but old files are not being deleted.

Conditions:
- ilx configured
- ilx plugin restarted

Impact:
The presence of too many of these leftover files might prevent merged from rolling up stats and providing graphs and cause such errors:

err merged[8523]: 011b0900:3: TMSTAT error tmstat_remerge: Cannot allocate memory.

Workaround:

1035661-4 : REST Requests return 401 Unauthorized when using Basic Auth

Links to More Info: BT1035661

Component: TMOS

Symptoms:
REST Requests are intermittently failing with a 401 error.

The restjavad-audit.*.log shows these requests are closely preceded by a 503 response from /mgmt/tm/auth/source.

Conditions:
Triggered when a REST request comes in using Basic Auth while an asynchronous task is executing on the BIG-IP.

An example of an asynchronous task is the BIG-IP processing an AS3 declaration.

Impact:
REST requests will fail with a misleading response code and for no readily apparent reason.

Workaround:
Use token based authentication for REST requests.


1035121-4 : Configsync syncs the node's monitor status

Links to More Info: BT1035121

Component: TMOS

Symptoms:
After config sync, nodes may be marked marked down when they are up, even if the monitor determines that the node is up.

The logs will show something similar to :

notice mcpd[8091]: 010714a0:5: Sync of device group /Common/device_trust_group to commit id 1 6986973310536375596 /Common/xxxxxxxx 1 from device /Common/yyyyyyyy

notice mcpd[8091]: 01070640:5: Node /Common/node1 address 10.10.100.1 monitor status down. [ /Common/icmp: up ] [ was up for 0hr:3mins:15sec ]
notice mcpd[8091]: 01070640:5: Node /Common/node2 address 10.10.100.2 monitor status down. [ /Common/icmp: up ] [ was up for 0hr:3mins:15sec ]

The node/pool member/pool/virtual server will be marked down.
Checking the actual monitor it will be up, tcpdump will show successful monitor transactions.

Conditions:
1. Two or more devices in a sync/failover device group
2. The config sync from-device has marked nodes down
3. A config sync occurs

This can occur on both incremental and full config sync.

Impact:
The node's monitor status is synced to the peer device. If the from-device's monitor was unable to reach the nodes and was marking the nodes as DOWN, then the node status will be set to DOWN on the other device, even if the monitor is successfully connecting to the node. This can cause a traffic disruption.

Note: the opposite can occur, where a "node up" status is sent to a device whose monitor is failing to connect to the nodes due to a network issue.

Workaround:
If a device is in this state, you can work around this issue by doing one of the following:

-- Save and reload the configuration on the device with the bad state
   tmsh save sys config && tmsh load sys config

-- Perform a full-load sync from the peer device to the affected device:
   (On the peer) tmsh run cm config-sync force-full-load-push to-group group-name


1035017-6 : Remove unused CA-bundles

Component: TMOS

Symptoms:

- Apply request logging on the same virtual server
- Send HTTP request to connect to a Host via the explicit virtual server

Impact:
HTTP_STATCODE not found in the logs captured from request logging


1034865-1 : CACHE::enable failed on private/no-store content

Links to More Info: BT1034865

Component: Local Traffic Manager

Symptoms:
BIG-IP provides a possibility to cache HTTP responses with RAMCACHE feature. When a response has either "Cache-Control: private" or "Cache-Control: no-store", the CACHE::enable setting allows the content to be cached. This option was removed when a fix to ID 360047 was introduced.

Conditions:
-- A virtual server has a web-acceleration profile without a policy.
-- An iRule has CACHE::enable command, overwriting Cache-Control header's values "no-store" and/or "private".

Impact:
BIG-IP always requests for a response from the origin web server even when a response is cacheable, putting extra load on the origin web server.


1034509-6 : Sensor read errors on VIPRION C2200 chassis

1034217-2 : Quic_update_rtt can leave ack_delay uninitialized.

Links to More Info: BT1034217

Component: Local Traffic Manager

Symptoms:
Retransmission times become very long if there is packet loss near the beginning of the connection.

Conditions:
-- Basic QUIC configuration.
-- The first couple of packets in the connection reaches an uninitialized variable path before the connection reaches the ESTABLISHED state.

Impact:
Uninitialized ack_delay variable could be any value and cause RTT measurements to be unusually large. That could cause retransmission times to be very long if there is packet loss near the beginning of the connection.

Workaround:
N/A

1033537-4 : Cookie persistence profile only examines the first cookie.

Links to More Info: BT1033537

Component: Local Traffic Manager

Symptoms:
The cookie persistence profile does not process multiple cookies with the same name. If that cookie is not valid for the selected pool or if it fails to decrypt, if encryption is enabled, it stops - even if there are other cookies of the same name.

Conditions:
-- Virtual server with an HTTP profile and a cookie persistence profile.
-- Multiple cookies with the same name arrive from the client.
 They can appear in a single Cookie header or two separate headers.
-- This can occur with cookie encryption enabled or disabled.

Impact:

1033333-4 : FIPS: importing a stub SSL key file results in 2 keys that share the same FIPS device

Links to More Info: BT1033333

Component: TMOS

Symptoms:
The 'tmsh list sys crypto key' command lists multiple keys with the same FIPS ID.

Conditions:
-- BIG-IP using a FIPS HSM
-- Import the stub FIPS key file contents (the filestore certificate_key file object) into the system as a new file object.

Impact:
Two object points to same key stored in the FIPS HSM. If one of the two objects are deleted, the key stored in the HSM will be deleted. This will result in traffic failures, i.e. TLS handshake failures.

Workaround:
Do not create a second MCP SSL key object by importing the stub key file content from the filestore.


1033025-4 : TMM might crash when unsupported bot iRule is used

1030533-1 : The BIG-IP system may reject valid HTTP responses from OCSP servers.

Links to More Info: BT1030533

Component: Local Traffic Manager

Symptoms:
When this happens, the BIG-IP system can be seen closing the TCP connection to the OCSP server prematurely (for instance, as soon as the HTTP response headers are received, before the response body is transmitted).

If log.keymgmtd.level is set to debug, an error similar to the following example will be logged to the /var/log/ltm file:

Jun 22 14:40:08 bigip1.local debug tmm[9921]: 01a40004:7: OCSP validation result of certificate(/config/filestore/files_d/Common_d/certificate_d/:Common:endpoint-intermediate_69993_1): OCSP response - (connection - HTTP error), certificate status - (error), lifetime - 10.

Conditions:
The server uses a Content-Type HTTP header in its response that isn't just "application/ocsp-response" (for instance, it may include a charset specification after that string, or the string may use a mix of uppercase and lowercase letters).

Impact:
Valid HTTP responses from OCSP servers are rejected. OCSP stapling and OCSP validation are not available on the BIG-IP system.

Workaround:
If you control the OCSP server and are able to customize its HTTP response headers, setting the Content-Type to simply "application/ocsp-response" (all lowercase) is a workaround for this issue.

Otherwise, no workaround exists.

Links to More Info: BT1028081

Component: Access Policy Manager

Symptoms:
1. Users connecting with F5 Access from an Android device see string "function () {[native code]}" in the Logon Page Form 'Username' field.
2. This issue only affects the F5 Access embedded browser. It works fine when connecting from the same Android device using Chrome. F5 Access from iOS is also working fine.

Conditions:

1027961-2 : Changes to an admin user's account properties may result in MCPD crash and failover

Links to More Info: BT1027961

Component: TMOS

Symptoms:
-- The mcpd process fails with a segmentation fault and restarts, leaving a core-dump file.
-- Active sessions in the Configuration Utility report "unable to contact BIG-IP device".
-- Various processes may record entries into the "ltm" log saying "Lost connection to mcpd."

Conditions:
-- Changes to properties of administrative user-login accounts are occurring.
-- A user account being changed has a current, active session in the Configuration Utility GUI.

Impact:
The failure and restart of mcpd will trigger a restart of many other processes, including the TMM daemons, thus interrupting network traffic handling. In high availability (HA) configurations, a failover will occur.

Workaround:
Before making changes to the account properties of an administrative user, where the changes affect the role, make certain that all GUI Configuration Utility sessions opened by that user are logged out.


1027805-4 : DHCP flows crossing route-domain boundaries might fail.

Links to More Info: BT1027805

Component: Local Traffic Manager

Symptoms:
DHCP flows crossing route-domain boundaries might fail.

Conditions:
Example of a configuration leading to the problem:
- route-domain RD%2 with parent defined as route-domain RD%1.
- Virtual-server in route-domain RD%2.
- Pool member configured in RD%2 (sharing IP addressing with RD1)
- DHCP client connects to the virtual-server in route-domain RD%2.
- Route lookup for a pool member ends up with connection in route-domain RD%1

Impact:
The second and subsequent DHCP clients requests will not be forwarded to the DHCP pool members.

Workaround:
When configuring a DHCP pool member, use the ID of the parent route-domain (the one that will be returned by a route-lookup for the pool member's IP address).


1027481-3 : 'error: /bin/haloptns unexpected error -- 768' log messages generated on A110 and D112 platforms

1027237-1 : Cannot edit virtual server in GUI after loading config with traffic-matching-criteria

Links to More Info: BT1027237

Component: TMOS

Symptoms:
After creating a virtual server with a traffic-matching-criteria and then loading the configuration, you are unable to make changes to it in the GUI. Attempting to do so results in an error similar to:

0107028f:3: The destination (0.0.0.0) address and mask (::) for virtual server (/Common/test-vs) must be be the same type (IPv4 or IPv6).

Conditions:
-- A virtual server that has traffic-matching-criteria (i.e., address and/or port lists).

Unable to use the GUI to edit the virtual server.

Workaround:
Use TMSH to modify the virtual server.


1026989-1 : More specific dynamic or static routes created for application traffic processing can erroneously replace the route to the management subnet.

Links to More Info: BT1026989

Component: TMOS

Symptoms:
When a dynamic or static route is instantiated for application traffic processing, protection exists at configuration-validation time to ensure that the new route does not overwrite how the management port's subnet is accessed.

To do so, the destination of the new route is compared to the management port's subnet. If the two match, the new route is only instantiated in TMM, but not in the Linux host's routing table.

The issue is this logic fails when the new route is a subset of the management port's subnet. For example, if the new route is to destination 10.215.50.0/25, and the management port's subnet is 10.215.50.0/24, the new route will be added to both TMM and the Linux host, bypassing the aforementioned protection.

Instead, the logic should check for overlapping subnets, not just strict equality.

Conditions:
- A dynamic or static route whose destination partially overlaps with the management port's subnet is added to or learnt by the system.

Impact:
A new and more specific route for part of the management port's subnet is added to the Linux host's routing table.

Part of the management port traffic can fail or be misrouted via a TMM interface.

If multiple routes of this kind are instantiated (e.g. 10.215.50.0/25 + 10.215.50.128/25), the whole management port's subnet can be overtaken.

Workaround:
Redesign your network and then reconfigure the BIG-IP system so that TMM does not need access to the management port's subnet or part of it (thus negating the need to create a route to that destination in the first place).

If this is not possible, you can temporarily resolve the issue by using the `route` or `ip` utility on the Linux host subsystem to manually fix the routing table. However, the issue will occur again the next time the problematic route is loaded or learnt by the system.


1026973-1 : Static routes created for application traffic processing can erroneously replace the route to the management subnet.

Links to More Info: BT1026973

Component: TMOS

Symptoms:
If a static route is added via "tmsh create net route" (or equivalent configuration ingestion system), and this route's destination matches the management port's subnet, the protection that prevents the new route from being propagated to the Linux kernel will initially work, but will fail after mcpd is restarted or the system is rebooted.

Conditions:
- A static route whose destination matches the management port's subnet is added to the system.

- The system is rebooted or mcpd is restarted.

Impact:
The directly-connected route for the management port's subnet appearing in the Linux host's routing table is replaced, or complemented, by a new and unnecessary route.

In either case, management port traffic can fail or be misrouted via a TMM interface.

Workaround:
Align your network and the BIG-IP system so that TMM does not need access to the management port's subnet (thus negating the need to create a route to that destination in the first place).

If this is not possible, you can temporarily resolve the issue by using the `route` or `ip` utility on the Linux host subsystem to manually fix the routing table. However, the issue will occur again the next time mcpd or the system restarts.


1026861-3 : Live Update of Browser Challenges and Anti-Fraud are not cleaned up

Links to More Info: BT1026861

Component: TMOS

Symptoms:
When installing live updates of either Browser Challenges (ASM) or Anti-Fraud (FPS), the update file remains in the system, taking up disk space and increasing config sync size.

Conditions:
Installing Live Update files of either Browser Challenges (part of ASM) or Anti-Fraud (part of FPS).

Impact:
Increased disk size, config size, and config-sync size.

Workaround:
It is possible to manually clean up old, unused Live Update files using TMSH or REST:
tmsh delete security datasync update-file datasync-global/<file>

Important: Use caution, as deleting update-files that are in use could cause the system to go offline or get out of sync. The in-use update files can be observed under the GENERATION PROFILES section of the /var/log/datasyncd.log file.

Note: There is no auto-completion on the 'update-file' keyword.


1026813-7 : LCD IP address is missing from /etc/hosts on iSeries

Links to More Info: BT1026813

Component: Global Traffic Manager (DNS)

Symptoms:
On iSeries platforms, /etc/hosts is missing an entry for the LCD IP address, 127.4.2.2.

Conditions:
Run any iSeries appliance.

Impact:
- BIG-IP generates reverse DNS requests for the LCD.
- /var/log/touchscreen_lcd lists the IP address "127.4.2.2" as the hostname

Workaround:
Add an entry for the LCD to /etc/hosts by modifying the 'remote-host' global settings, by running the following tmsh command:

tmsh modify sys global-settings remote-host add { lcd { addr 127.4.2.2 hostname lcd } }
tmsh save sys config

Or, in the BIG-IP GUI, System >> Configuration : Device : Hosts


1026781-3 : Standard HTTP monitor send strings have double CRLF appended

Links to More Info: BT1026781

Component: Local Traffic Manager

Symptoms:
Standard (bigd-based, not In-TMM) HTTP monitors have a double CRLF appended (\r\n\r\n) to the send string. This does not comply with RFC1945 section 5.1 which states requests must terminate with a single CRLF (\r\n). This non-compliant behavior can lead to unexpected results when probing servers.

Conditions:
Standard bigd (not In-TMM) HTTP monitors

Impact:
Servers probed by these non-RFC-compliant HTTP monitors may respond in an unexpected manner, resulting in false negative or false positive monitor results.

Workaround:
There are several workarounds:

1. If running 13.1.0 or later, switch monitoring from bigd-based to In-TMM. In-TMM monitors properly follow RFC1945 and will send only a single CRLF (\r\n)

2. Remain with bigd-based monitoring and configure probed servers to respond to double CRLF (\r\n\r\n) in a desired fashion

Depending on server configuration, a customized send string, even with the double CRLF, may still yield expected responses.


1026621-1 : DNS cache resolver could not connect to remote DNS server with snatpool if multiple routes exist

Component: Global Traffic Manager (DNS)

Symptoms:
DNS query could not be resolved properly.

Conditions:
1. dnscache.matchwildcardvip is enabled
2. Multiple possible routes to destination DNS server exist. This can be triggered by either using a gateway pool, or using dynamic routing with multiple equal paths available.

Impact:
Unable to use snatpool for cache resolver.

Workaround:
Ensure only a single route to destination exists, or disable dnscache.matchwildcardvip

NOTE: With dnscache.matchwildcardvip disabled, snatpool will not be used.

Conditions:
Using CGNAT PBA, logging to a NetFlow/IPFIX log destination, and AFM is not enabled.

Impact:
CGNAT PBA events containing the observationTimeMilliseconds Information Element will report incorrect values for this field.

Workaround:
1) Enable AFM module, or
2) Enable lsn-legacy-mode in the log profile

1026273-4 : HA failover connectivity using the cluster management address does not work on VIPRION platforms&start;

Links to More Info: BT1026273

Component: TMOS

Symptoms:
Upon upgrade to an affected version, failover communication via the management port does not work. You may still see packets passing back and forth, but the listener on the receiving end is not configured, and therefore the channel is not up.

Here are a few symptoms you may see:
-- Running 'tmsh show cm failover-status' shows a status of 'Error' on the management network.

-- Running 'tmctl' commands reports the disconnected state:

10.76.7.8->17.1.90.2:1026 1623681404 1

-- Looking at 'netstat -pan | grep 1026 command output, you do not see the management port listening on port 1026:
Example (notice that the management IP from the above example of 10.76.7.9 is not listed):
# netstat -pan | grep 1026
udp 0 0 10.10.10.10:1026 0.0.0.0:* 6035/sod

-- Listing /var/run/ contents shows that the chmand.pid file is missing:
 # ls /var/run/chmand.pid
ls: cannot access /var/run/chmand.pid: No such file or directory

Conditions:
-- Running on VIPRION platforms
-- Only cluster management IP address is configured: No cluster member IP addresses are configured
-- Install a software version where ID810821 is fixed (see https://cdn.f5.com/product/bugtracker/ID810821.html)
-- Management IP is configured in the failover configuration

Impact:
If only the management is configured for failover or there are communication issues over the self IP (such as misconfigured port lockdown settings), then the devices may appear to have unusual behavior such as both going active.

Workaround:
-- Configure a cluster member IP address on each individual blade in addition to the Cluster management IP address.

1025513-1 : PAM Authenticator can cause authorization failure if it fails to lock /var/log/tallylog

Links to More Info: BT1025513

Component: TMOS

Symptoms:
The following JSON content can be seen in the HTTP 401 response. (By looking at the capture or RESTful client)

{"code":401,"message":"Authorization failed: no user authentication header or token detected. Uri:http://localhost:8100/mgmt/tm/ltm/pool/?expandSubcollections=true Referrer:<ip_address> Sender:<ip_address>,"referer":<ip_address>,"restOperationId":12338804,"kind":":resterrorresponse"}


Contention for /var/log/tallylog lock might result in users failing to authenticate correctly. As a result of this issue, you might see the following message:

 PAM Couldn't lock /var/log/pam/tallylog : Resource temporarily unavailable.

Conditions:
High concurrent authentication attempts may trigger this issue. For example, opening a connection, using basic authentication, performing a query (for example, get node list, get virtual address list, and set pool min active members), and then closing the connection. If done frequently enough, there is an occasional authentication failure.

Impact:
This intermittent auth issue results in failure of some auth request.

Workaround:
Since this is an intermittent authentication failure, wait a few seconds and then attempt to rerun auth request.

For automation tools, please use token-based authentication.


1025261-3 : When restjavad.useextramb is set, java immediately uses more resident memory in control plane

Links to More Info: BT1025261

Component: TMOS

Symptoms:
When restjavad.useextramb is set, java immediately reserves more memory and the process size (RSS) increases.

Conditions:
When restjavad.useextramb and when provision.extramb is set to a non-default value.

Impact:
The restjavad process size will use more RSS.

Workaround:
Revert the restjavad.useextramb value or set provision.extramb higher to compensate.


1025089-1 : Pool members marked down by database monitor due to stale cached connection

Links to More Info: BT1025089

Component: Local Traffic Manager

Symptoms:
By default, BIG-IP database monitors (mssql, mysql, oracle, postgresql) are configured to keep a connection to the database server open between monitor probes to avoid the overhead of establishing the network connection to the database server for each query operation.
If this cached network connection times out or is dropped by the database server, it is marked as "stale" when the next probe occurs, and a new connection is made during the next scheduled monitor probe.
In the meantime, due to the lost connection, the monitored pool member may be marked DOWN until the next scheduled monitor probe. This is more likely to occur when a database monitor is used to monitor a GTM pool member instead of an LTM pool member, due to differences between how monitors are configured for GTM versus LTM.

Conditions:
This may occur under the following conditions:
-- GTM or LTM pool members are monitored by a database monitor, configured such that a single probe failure will mark the member DOWN. (Such configuration may be more common for GTM monitors.)
-- Either the database server times out or drops the connection for some reason, or no database monitor probes are sent to the database server within a 5 minute interval.

Impact:
-- GTM or LTM pool members monitored by a database monitor may be marked DOWN temporarily if the network connection to the database server is dropped or times out.

-- High CPU utilization is observed on control plane cores.

Workaround:
To work around this issue, perform one of the following actions:
-- Configure the database (mssql, mysql, oracle, postgresql) monitor with a "count" value of "1". This prevents the caching/reuse of network connections to the database server between probes. Thus there is no cached connection to time out/get dropped. However, the overhead of establishing the network connection to the database server will be incurred for each probe.
-- Configure the database monitor "interval" and "timeout" values (for an LTM monitor), or the "interval", "timeout", "probe-attempts", "probe-interval" and "probe-timeout" values (for a GTM monitor) such that multiple failed monitor probes are required before the monitored member is marked DOWN.

1024421-2 : At failover, ePVA flush leads to clock advancing and MPI timeout messages in TMM log

Links to More Info: BT1024421

Component: TMOS

Symptoms:
TMM log shows clock advancing and MPI timeout messages:

notice slot1 MPI stream: connection to node aborted for reason: TCP RST from remote system (tcp.c:5201)
notice slot1 tmm[42900]: 01010029:5: Clock advanced by 6320 ticks

Conditions:
-- pva.standby.flush DB key set to 1 (enabled). The default is 0.
-- Processing high traffic volume for some time

Impact:
Upstream switch could receive flow response from both active and standby units and cause a traffic disturbance.


1024301-1 : Missing required logs for "tmsh modify disk directory" command

Links to More Info: BT1024301

Component: TMOS

Symptoms:
In case of failure of "tmsh modify disk directory" command, log which help to find reason for failure are getting missed.

Conditions:
Attempt to resize some volumes via the "tmsh modify disk directory" command

Impact:
Not able to find failure reason for resize of volumes.

Workaround:
Manually running the resize2fs command, can give the reason for failure.


1024269-1 : Forcing a file system check on the next system reboot does not check all filesystems.

Links to More Info: BT1024269

Component: TMOS

Symptoms:
Forcing a file system check on the next system reboot, as described in K73827442, does not check all filesystems. This should not be the case and is a regression compared to previous BIG-IP versions.

After the reboot, you can inspect which filesystems were checked by running the following command:

journalctl --all --no-pager | grep -i fsck

Conditions:
A BIG-IP Administrator follows the procedure to force a file system check on the next system reboot.

Impact:
Some filesystems will not be fixed, and will continue to be corrupted. This can have a number of negative consequences. For instance, enlarging a filesystem (via the 'tmsh modify sys disk directory' command) can fail when a filesystem is dirty.

Workaround:
You can boot the system from the Maintenance Operating System (MOS), and perform all needed file system check operations from there. To boot the system into MOS, simply type 'mosreboot'. Note that once the system reboots into MOS, you will need video console access (for VE systems) or serial console access (for hardware systems) to be able to run fsck and the reboot the system into a regular BIG-IP boot location.

For more information on MOS, please refer to K14245.

1023829-2 : Security->Policies in Virtual Server web page spins mcpd 100%, which later cores

Links to More Info: BT1023829

Component: TMOS

Symptoms:
With a large number of VLANs (3000+) and virtual servers (2000+), the virtual server list page consumes excessive resources, eventually leading to a mcpd crash.

Conditions:
-- A huge number of VLANs and virtual servers exist.
-- The virtual server list page is displayed

Impact:
Page becomes inaccessible. Mcpd may crash. Traffic and control plane disrupted while mcpd restarts.


1023817-2 : Misleading "Enabling NAT64 for virtual server with security NAT policy configured is redundant/not required." warning

Links to More Info: BT1023817

Component: TMOS

Symptoms:
While loading the configuration or specifying that NAT64 should be disabled on a virtual server, a warning is displayed or logged:

"Enabling NAT64 for virtual server with security NAT policy configured is redundant/not required."

This warning should only be displayed when a virtual server has both NAT64 enabled and a security NAT policy present, but may occur incorrectly even when NAT64 is disabled.

Conditions:
This warning may be incorrectly generated when all of these conditions are met:

-- a multi-bladed VIPRION
-- virtual servers in the configuration security NAT policies
-- receiving a ConfigSync from a peer, or running "tmsh load sys config" on the primary blade

Impact:
An erroneous warning is logged. It can be safely ignored.


1023529-2 : FastL4 connections with infinite timeout may become immune to manual deletion and remain in memory.

Links to More Info: BT1023529

Component: Local Traffic Manager

Symptoms:
Command "tmsh show sys tmm-traffic" reports non-zero number of current connections but "tmsh show sys connection" shows nothing.

Conditions:
-- A virtual sever with fastL4 profile with infinite timeout enabled and an iRule containing "after" command. Having "-periodic" argument makes the problem more prominent.
-- Aggressive sweeper activated due to low memory conditions.

Impact:
Connections that were supposed to be removed by aggressive sweeper but were waiting for completion of an iRule may end up in a state where they are not reported by "tmsh show sys connection." Because of this issue, these connections cannot be deleted manually using 'tmsh del sys connection", but remain in memory. Their presence can be confirmed by non-zero number of current connections shown by "tmsh show sys tmm-traffic". Because of the infinite timeout setting, they will not timeout by themselves either.

Workaround:
N/A


1023461-2 : Multiple entries for CGNAT when PBA pools allocation is defined: for each request, a new entry is created

Links to More Info: BT1023461

Component: Carrier-Grade NAT

Symptoms:
Two pools are configured, for example:
A: any destination
B: destination 8.8.8.8

1. Making connections and utilizing port block allocation (PBA) pool A works as expected; pools are correctly allocated and released as needed.
2. When a client has active PBA pool A allocated and requests pool B (because of connectivity to specific destination IP), then each subsequent connection request from that client results in new PBA pool B allocation.

Conditions:
Multiple rules are defined to configure PBA.

Impact:
If a request does not belong to the first pool then it will not belong any other, so the system creates a new pool.

Workaround:
None


1022997-1 : TCP segments with an incorrect checksum are transmitted when the sock driver is used in AWS deployments (e.g., 1NIC)

Links to More Info: BT1022997

Component: TMOS

Symptoms:
Deployments on AWS that use the sock driver (1NIC, for example) transmit packets with bad checksums when TSO/GSO is required. This causes significant delays as TMM re-segments the packets with correct checksums for retransmission, and may cause some operations to time out (such as configsyncs of large configurations).

Conditions:
-- BIG-IP Virtual Edition (VE) using the sock driver on AWS (all 1NIC deployments use this)
-- TSO/GSO required due to MTU limitations on one or more VLANs

Impact:
-- Delayed packets.
-- Possible timeouts for some operations (configsyncs, for example).

Workaround:
Modify (or create, if not present) the file /config/tmm_init.tcl on the affected BIG-IP systems, and add the following line to it:

ndal force_sw_tcs off 1d0f:ec20

Then restart TMM:

bigstart restart tmm

Note: Restarting TMM will cause a failover (or an outage if there is no high availability (HA) peer available).


1022973-2 : Sessiondb entries related to Oauth module not cleaned up in certain conditions

Links to More Info: BT1022973

Component: Access Policy Manager

Symptoms:
When an OAuth AS is configured with a refresh lifetime of '0', this implies that the refresh token lifetime is infinite. This leads to all sessiondb entries related to this refresh token (including associated access token entries in sessiondb) to have infinite lifetime.

Conditions:
Refresh token lifetime is set to '0'.

Impact:
User will see consistent and persistent increase in memory consumption by TMM, potentially leading to out-of-memory situation.

Workaround:
Do not set refresh token lifetime to '0'.


1022877-3 : Ping missing from list of Types for OAuth Client

Component: Access Policy Manager

Symptoms:
Ping is missing from the 'Type' dropdown menu in Access ›› Federation : OAuth Client / Resource Server : OAuth Server ›› New OAuth Server Configuration...

Conditions:
-- Affected BIG-IP version
-- Add new Oauth server configuration from Access :: Federation : OAuth Client / Resource Server : OAuth Server :: New OAuth Server Configuration...

Impact:
Oauth client configuration for the server of type 'Ping' cannot be created via GUI

Workaround:
Use tmsh to create the configuration, e.g.:

tmsh create apm aaa oauth-server <server name> provider-name Ping dns-resolver-name <dns-resolver-name>

1022493-4 : Slow file descriptor leak in urldbmgrd (sockets open over time)

Links to More Info: BT1022493

Component: Access Policy Manager

Symptoms:
Unix domain sockets are opened and never closed in urldbmgrd. This is a very slow leak over time.

Conditions:
SWG or URLDB is provisioned.

Impact:
Urldbmgrd may hit a limit of open file descriptors, and may eventually core and restart. When urldbmgrd restarts, urldb also restarts. This may result in a momentary instant where URL categorization is not available.

Workaround:
Restarting urldbmgrd will clear the open file descriptors. Performing a forced restart during a time of no traffic will mitigate the risk of urldbmgrd restarting at an inconvenient time if there are too many sockets open.

"bigstart restart urldbmgrd" will restart the daemon.

   May 14 15:34:04 fqdn.device.com notice pendsect[11461]: No known drives detected for pending sector check. Exiting

Conditions:
- i2x00 or i4x00 platform with the Seagate brand HDD

Impact:
Cosmetic

Workaround:
You can mitigate the cosmetic log issue by suppressing the pendsec utility.

Login to BIG-IP using SSH
 
 Navigate to /etc/cron.daily
# cd /etc/cron.daily
 
Create new directory called suppress
# mkdir suppress
 
Move the pendsect cron job to suppres
# mv pendsect suppress

-- The 'load sys config' command is run.

Impact:
Upgrading (load sys config) takes a lot of time of time to complete, which sometimes causes Packet Correlation Classification Daemon (pccd) to fail.

If pccd fails, the system is unable to detect and compile firewall configuration changes, meaning that changes made to the firewall configuration are not enforced.

Note: The firewall configuration that was running before pccd goes down continues to be enforced; only changes are not enforced.

Workaround:
None


1020041-3 : "Can't process event 16, err: ERR_NOT_FOUND" seen in tmm logs

Component: Policy Enforcement Manager

Symptoms:
The following message may be logged to /var/log/tmm*

   Can't process event 16, err: ERR_NOT_FOUND

Conditions:
Applying a PEM policy to an existing session that already has that policy (eg, through an irule using 'PEM::subscriber config policy referential set xxxx'

Impact:
Since the PEM policy is already applied to the session, the failure message is essentially cosmetic, but it can cause the tmm logs to grow in size if this is happening frequently.

1019429-1 : CMP Forwarded flows do not get syncache counter decremented when only server-side is PVA accelerated

Links to More Info: BT1019429

Component: TMOS

Symptoms:
Virtuals with CMP forwarded flows and PVA acceleration may see a higher than expected syncache counter which can lead to permanent syncookie activation.

Also, under certain conditions the internal listeners used for config-sync may have syncookies activated. Logs will show the syncookie counter increasing after every activation.

bigip1 warning tmm1[18356]: 01010038:4: Syncookie counter 9830 exceeded vip threshold 2496 for virtual = 192.168.1.1:4353
bigip1 warning tmm1[18356]: 01010038:4: Syncookie counter 9834 exceeded vip threshold 2497 for virtual = 192.168.1.1:4353

Conditions:
-- Virtual servers with CMP forwarded flows - commonly occurring when the FTP profile is in use.
-- A platform with PVA acceleration enabled.
-- Only the server-side flow of a connection is offloaded to hardware.

Impact:
Elevated syncache_curr, epva_connstat.embryonic_hw_conns, epva_connstat, embryonic_hw_tcp_conns stas. Improper syncooke activation. Syncookie activation on the config-sync listener may cause config-sync to fail.

Workaround:
Remove the ftp profile or disable PVA acceleration:

modify sys db pva.acceleration value none

Workaround:
Reboot the system to restore the systemd services.


1019261-1 : In-TMM HTTPS monitor with SSL Profile set to None does not use serverssl profile.

Links to More Info: BT1019261

Component: Local Traffic Manager

Symptoms:
HTTPS monitors with SSL profile set to None (default) will not use the default ServerSSL profile of "serverssl" when In-TMM monitoring is enabled. Instead, another internal ServerSSL profile is used which has different values from "serverssl".

Conditions:
-- In-TMM monitoring is enabled
-- HTTPS monitor(s) with SSL profile field is set to the default of "None"

Impact:
The TLS settings for the HTTPS monitor monitor probes will not match those of the ServerSSL "serverssl" profile and may cause unexpected behavior such as utilizing TLS 1.3 (disabled by default in the "serverssl" profile) or random session IDs.

Workaround:
Specify a ServerSSL profile in every HTTPS monitor when using In-TMM monitoring.

Attaching the profile "serverssl" will result in the same behavior that SSL Profile "none" should provide, given that the "serverssl" profile should be the default.


1019129-4 : Changing syslog remote port requires syslog-ng restart to take effect

Links to More Info: BT1019129

Component: TMOS

Symptoms:
Modified remote port in syslog configuration takes effect only after restart of the syslog-ng.

Conditions:
-- Configure the remote syslogs and allow some time to pass.
-- Change the local IP or remote port in syslog config.

Impact:
Change does not occur until you reboot or restart syslog-ng.

Workaround:
To cause the change to occur, restart syslog-ng:
bigstart restart syslog-ng


1018877-2 : Subsession variable values mixing between sessions

Links to More Info: BT1018877

Component: Access Policy Manager

Symptoms:
Subsession variable lookup internally assumes that a complete session DB lookup name (Session ID + Subsession key) is used. However, when using the lookup table, only the subsession key is passed in.

Conditions:
Subsession variables are referenced in the Per-Request Policy outside of the Subsession without the Session ID.

Impact:
A Per-Request Policy execution may get the value of the subsession variable from a different APM session.

Workaround:
Add the session ID to the reference to the subsession variables used in Per-Request Policies.


1018765-1 : Changing the sshd port breaks some BIG-IP utilities on a multi-bladed system

Links to More Info: BT1018765

"tmsh reboot slot ..."

or

qkview

or

any command using clsh

or

ssh slot<slot number>

Conditions:
-- Chassis system with multiple blades.
-- Default sshd port was modified.

Impact:
Unable to run commands on secondary blades.

Workaround:
-- Reconfigure SSHD to run on the default port, 22.

or

-- Specify an explicit port when using ssh and log in to each blade to run the desired commands, e.g. "ssh -p 40222 slot2"


1018673-1 : Virtual Edition systems replicate host traffic to all TMMs when a multicast MAC address is the traffic's nexthop

Links to More Info: BT1018673

Component: TMOS

Symptoms:
When BIG-IP Virtual Edition receives a host packet that has a multicast MAC address as its nexthop, it will disaggregate this by forwarding it to all TMMs. This results in all TMMs egressing the packet.

Conditions:
-- BIG-IP Virtual Edition
-- A route is configured to a multicast MAC address
-- Host traffic (e.g. non-TMM monitors, ping, etc.) is routed to the multicast MAC address

Impact:
Extraneous packets are egressed from the BIG-IP.

Workaround:
Partial workaround for the case of monitors: use in-TMM monitors where possible. Otherwise, there is no workaround for this.

Conditions:
Using tmsh, create a Trunk, create a VLAN on the trunk, create a route-domain, then create a self IP address.

Impact:
Self IP address creation fails after route-domain creation.
Unable to run declarative-onboarding declaration.

Workaround:
Add a short delay after modifying/creating the route domain before creating the self IP address.

Note: Self IP address should be created after route-domain creation.


1017885-5 : Wildcard server-name does not match multiple labels in FQDN

Links to More Info: BT1017885

Component: Local Traffic Manager

Symptoms:
Wildcard server-name does not match multiple labels in FQDN
for example: *.domain.com matches a.domain.com or a.bc.domain.com, but it does not match domain.com but here multiple labels(a.bc.domain.com) are not matched to the wildcard (*.domain.com).

Conditions:
Client-ssl is configured with a wildcard server-name with the virtual server configured with multiple client-ssl profiles. The correct ssl profile (and therefore certificate) is chosen based on SNI from the client Hello.

Impact:
Generates default profile/certificate when trying to match with multiple labels using wildcard, when it should generate correct certificate matched to the wildcard in server name.

Workaround:
N/A


1017857-1 : Restore of UCS leads to incorrect UID on authorized_keys&start;

Links to More Info: BT1017857

Component: TMOS

Symptoms:
After restoring a UCS from a different BIG-IP device, the admin user is unable to log in via SSH using SSH public key authentication.

Conditions:
-- Create a UCS on one BIG-IP system where a UCS archive has been restored in the past (including by an upgrade)
-- Import the UCS to a different BIG-IP system and load it

Impact:
You are unable to log in as the admin user via SSH using key-based authentication.
NOTE: Password authentication works without any issues.

Workaround:
Change the owner of /home/admin/.ssh/authorized_keys to 'root', by running the following command:

    chown root /home/admin/.ssh/authorized_keys

This command can also be run via iControl REST using the /mgmt/tm/util/bash endpoint.


1017801-1 : Internal listeners (cgc, ftp data, etc) all share the same listener_key stats

Links to More Info: BT1017801

Component: Local Traffic Manager

Symptoms:
Internal stats are not accurate because they are shared across multiple listener types

Conditions:
This can occur when multiple virtual server types are in use and passing traffic.

Impact:

1017557-1 : ASM Plugin Abort reset for chunked response without proper terminating 0 chunk followed by FIN

Links to More Info: BT1017557

Component: Application Security Manager

Symptoms:
ASM BD sends a reset back to the client when the backend server sends a response without proper terminating 0 chunk followed by FIN.

Conditions:
- ASM provisioned
- ASM policy attached to a virtual server
- Backed server sends a bad chunked response

Impact:
Valid requests can be reset.

Workaround:
Any one of the following workarounds can be applied.

-- Fix backed server behavior.
-- Fix bad response using iRule, appending proper terminating 0 chunk
-- Change ASM internal /usr/share/ts/bin/add_del_internal update bypass_upon_load 1


1017421-4 : SASP Monitor does not log significant error conditions at default logging level

Links to More Info: BT1017421

Component: Local Traffic Manager

Symptoms:
Most error conditions encountered by the SASP monitor are not logged at the default logging level ("error"). Most of the meaningful error conditions, including Exceptions, are logged at "info" or "debug" levels. Obtaining details to diagnose the SASP monitor issues requires reconfiguring sys db saspd.loglevel for a value of "info" or "debug".

Conditions:
-- Using the SASP monitor to monitor LTM pool members
-- Leaving the saspd.loglevel system DB variable configured at the default value of "error"

Impact:
Errors which occur intermittently or once while monitoring LTM pool members using the SASP monitor may not be diagnosable.

Workaround:
Configure the saspd.loglevel system DB variable with a value of "info" (for normal operations) or "debug" (if problems are occurring repeatedly).


1017261-7 : Configuraton update triggers from MCP to ASM are ignored

Links to More Info: BT1017261

Component: Application Security Manager

Symptoms:
If a stale/incorrect but running PID is present in /var/ts/var/install/ucs_install.pid, then ASMConfig will think it is in the middle of a UCS or Sync load event and ignore updates from MCP.

Conditions:
A UCS load event such as an upgrade or a config sync is interrupted and ASM is not restarted until another process reuses the process id from the upgrade.

Impact:
Updates from MCP are ignored which can cause:
* Missed sync events
* Missed updates for logging or pool configuration
* Missing security policies

Workaround:
Delete /var/ts/var/install/ucs_install.pid


1017149-1 : User-defined bot sigs that are created in tmsh don't overlap staged factory bot sigs

Component: Application Security Manager

Symptoms:
User-defined bot signatures that are created in tmsh are not enforced if there are similar factory bot signatures even when they are staged.

Conditions:
User-defined bot signature is created in tmsh and is matched also by staged factory bot signature.

Impact:
User-defined signature is not enforced correctly

Workaround:
Define user-defined bot signature using the GUI and if signature domain are needed but can't be configured by the GUI, define the domain in tmsh after the signature is created with:
tmsh mod security bot-defense signature <sig_name> domains replace-all-with { domains }


1017029-5 : SASP monitor does not identify specific cause of failed SASP Registration attempt

Links to More Info: BT1017029

Component: Local Traffic Manager

Symptoms:
On affected BIG-IP versions, upon startup, the SASP monitor sends a single Registration Request to the SASP GWM (Group Workload Manager) to initiate monitoring of configured LTM pool members. This Registration Request contains all configured LTM pools (SASP Groups) and members (SASP Group Members).

If an error is encountered by the SASP GWM with one of the SASP Groups in the request, the registration of all groups fails.
However, the GWM does not provide any indication of *which* Group or member does not match the GWM configuration, hindering troubleshooting efforts.

The current BIG-IP behavior does not allow identification of the specific pool/member or monitor that is misconfigured and thus responsible for the failed SASP Registration attempt.

Conditions:
This behavior occurs on affected BIG-IP versions when the LTM SASP monitor is configured to monitor members of multiple LTM pools, and when BIG-IP start/restarts/reboots or the configuration is loaded.

Impact:
If a single Registration Request fails, the GWM terminates the connection with the Load Balancer (BIG-IP SASP monitor). This behavior is defined by the SASP protocol and SASP GWM implementation.

As a result, the SASP monitor will mark all pool members DOWN that are monitored by the SASP monitor, halting traffic from flowing to all pools monitored by the SASP monitor.

When an error occurs during registration of the LTM pools (SASP Groups), the GWM does not provide any indication of *which* Group or member does not match the GWM configuration.
Since a single error message is returned by the SASP GWM for the entire Registration Request (for all SASP Groups), the SASP monitor cannot indicate which Group (pool/member) or monitor caused the error.

This hinders efforts to troubleshoot the cause of the failure, while all traffic has stopped flowing to the SASP-monitored pools.

Workaround:
To diagnose this issue, first enable saspd debug logging:
tmsh mod sys db saspd.loglevel value debug_msg
(Optional alternative values include deep_debug and debug, but provide less detail.)

With saspd debug logging enabled, a message like the following in /var/log/monitors/saspd.log confirms that an error occurred during the Registration step:
SASPProcessor::processRegistrationReply: received error registering workloads with GWM ##.##.##.###:3860: 69 'InvalidGroup'

If the above message is found to confirm this issue, the primary path to resolution should be for the BIG-IP administrator to very carefully compare the BIG-IP pool/member and sasp monitor configuration with the SASP GWM configuration, to identify any mismatches or inconsistencies between the configurations.

On the BIG-IP system, to help isolate the misconfigured LTM pool(s)/member(s) causing the SASP Registration failure:
1. Remove the sasp monitor from configured LTM pools/members one at a time, and observe whether any pool members still monitored by the sasp monitor are marked UP.
2. Add the sasp monitor back to configured LTM pools/members one at a time, in the same order as removed, except for the last LTM pool/member from which it was removed.
3. Save and reload the configuration, and check whether the LTM pools/members monitored by the sasp monitor are still marked UP.
4. Repeat as necessary if there appear to be multiple LTM pools/members causing a SASP Registration failure.


Alternately, it may be possible to choose a different monitor (using a more fault-tolerant protocol) to monitor the status of affected pool members.


1016921-3 : SSL Connection mirroring - session resumption does not occur on standby when the session ticket is enabled

Links to More Info: BT1016921

Component: Local Traffic Manager

Symptoms:
Eight-second delays occur on traffic through an SSL connection mirroring virtual server, and errors occur on the standby device:

crit tmm7[11598]: 01010025:2: Device error: crypto codec Couldn't create an OpenSSL EC group object OpenSSL error:0906D06C:PEM
err tmm7[11598]: 01010282:3: Crypto codec error: sw_crypto-7 Couldn't initialize the elliptic curve parameters.
crit tmm7[11598]: 01010025:2: Device error: crypto codec No codec available to initialize request context.

Conditions:
All of these conditions:
-- SSL connection mirroring enabled
-- Session tickets are enabled
-- High availability (HA) environment

and one of the following:
-- Running BIG-IP v14.1.4.1 or above (in the v14.1.x branch)
or
-- Engineering hotfix applied to v14.x/v15.x that has the ID760406 fix (see https://cdn.f5.com/product/bugtracker/ID760406.html)

Impact:
SSL traffic is significantly delayed and errors are thrown on the standby device.

Workaround:
Any one of the following could prevent the problem.

-- client-ssl profile cache-size 0.
-- client-ssl profile session-ticket disabled (default).
-- disable SSL connection mirror on virtual server.


1016909-1 : BIG-IP iRule commands FLOW::this or FLOW::peer can create zombie flows.

Links to More Info: BT1016909

Component: Local Traffic Manager

Symptoms:
Keeping a variable reference to FLOW::this or FLOW::peer in iRules can result in zombie connection flows that are never removed.

TMM memory use for 'connflow' and 'tclrule_pcb' are high, and do not match the number of current connections reported by the system.

Conditions:
-- iRule that uses FLOW::this or FLOW::peer, and stores the result of one of those commands into a variable.

Impact:
Increased memory use in TMM, which can eventually result in a TMM crash or traffic disruption while connections are removed using the connection sweeper.

Workaround:
Do not retain the result of 'FLOW::this' or 'FLOW::peer' in a variable in an iRule. Instead, either:

1. Use the variable directly, i.e.:
    log local0.warning: "The flow is [FLOW::this]"

2. Unset the variable when done, i.e.:
    set flow [FLOW::this]
    log local0.warning: "The flow is $flow"
    unset flow


If a system is already affected by this issue, the only way to free that memory is to restart TMM.


1016589-1 : Incorrect expression in STREAM::expression might cause a tmm crash

Links to More Info: BT1016589

Component: Local Traffic Manager

Symptoms:
Tmm restarts and generates a core file

Conditions:
An iRule uses STREAM::expression that contains certain strings or is malformed.

Stream expressions use a string representing a series of search/replace or search components. If there is more than one search-only component, this might cause tmm to crash.

The delimiter character used is the first character of each component search/replace pair. This example uses the '@' character as the delimiter, but it is malformed.

Given
  STREAM::expression "@dog@dot@cat@car@uvw@xyz@"
This would be interpreted as three items:
  search for "dog" replace with "dot"
  search for "at@"
  search for "r@uvw@xyz@"

This string should likely be:
  STREAM::expression "@dog@dot@@cat@car@@uvw@xyz@"
Which would be interpreted as
  search for "dog" replace with "dot"
  search for "cat" replace with "car"
  search for "uvw" replace with "xyz"

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Ensure that strings in STREAM::expression iRule statements do not have more than one search-only component and are well formed.

1015793-1 : Length value returned by TCP::payload is signed and can appear negative

Links to More Info: BT1015793

Component: Local Traffic Manager

Symptoms:
When an iRule uses TCP::collect, if the amount of received data being buffered exceeds 2147483647 octets, the value returned from [TCP::payload length] will appear as a negative integer.

Conditions:
An iRule has been written to use TCP::collect with a very high-volume input stream.

Impact:
The unanticipated negative value may confuse the iRule's logic, with unpredictable effects. In extreme cases, a disruption of the TMM could occur.

Workaround:
Convert the result of "TCL::payload length" to an unsigned integer before using it, e.g.:

    set curlen [expr { 0xffffffff & [TCP::payload length] }]

Note: the amount of accumulated payload still must not exceed 4,294,967,295 bytes (2^32-1).

1014361-2 : Config sync fails after provisioning APM or changing BIG-IP license

Links to More Info: BT1014361

Component: TMOS

Symptoms:
Clustered high availability (HA) devices cannot establish ConfigSync connection, and the prompt status reports disconnected.

MCPD is logging a message similar to this repeatedly, even though all TMMs are up and running:

err mcpd[4247]: 0107142f:3: Can't connect to CMI peer 192.0.2.1, TMM outbound listener not yet created

Conditions:
- In-tmm monitoring is enabled (the bigd.tmm db key is set to enable).

- A HTTP or HTTPS monitor has been configured with a send string which is not RFC-compliant. For instance, the following string incorrectly includes a space before the Host header:

"GET / HTTP/1.1\r\n Host: example.com\r\nConnection: Close\r\n\r\n"

Impact:
Pool member monitoring is impacted and unreliable.

Workaround:
Ensure that you specify a send string which is fully RFC-compliant (for instance, in the example above, remove the space before the Host header).

1012601-4 : Alarm LED and LCD alert cleared prematurely on startup for missing PSU input

Links to More Info: BT1012601

Component: TMOS

Symptoms:
Occasionally when starting up a BIG-IP system, if one PSU is connected but not supplying power, the corresponding amber alarm LED and "PSU status input lost" alert in the LCD menu can be incorrectly cleared after selecting System -> Power On from the LCD menu.

Conditions:
-- iSeries platforms
-- The BIG-IP device is powered on with one PSU connected and not supplying power

Impact:
The alarm LED is incorrectly turned off, and navigating to alerts on the LCD menu no longer shows a "PSU status input lost" alert after powering on.

Workaround:
Before powering on the BIG-IP device, check the alarm LED and navigate to alerts on the LCD screen. If there is a "PSU status input lost" alert, the corresponding power LED should be amber.

If the power LED is still amber after powering the system on but the alarm LED and LCD alert are cleared, please disregard the alarm LED and LCD in this case. The amber power LED is correct, and the PSU is still not supplying power.

Additionally, if you are logged into the console, running "bigstart restart chmand" will force a new "PSU status input lost" alert to be generated on the LCD and should also correct the alarm LED color to amber.


1012493-5 : Systemauth.primaryadminuser set to anything but 'admin' causes internal error for mcp-state check

Links to More Info: BT1012493

Component: TMOS

1012413-1 : Tmm performance impact for DDoS vector on virtual server when hardware mitigation is enabled

Links to More Info: BT1012413

Component: Advanced Firewall Manager

Symptoms:
When a DoS profile is attached to a virtual server, the mitigation limit is set to the system limit and not the HSB limit. This causes more packets to be handled by software. Depending on attack size, it could pass up to 200% of the set mitigation limit. This can impact tmm performance.

Conditions:
-- Dos profile is configured on virtual server.
-- Hardware platform that has HSB
-- Hardware mitigation is enabled

Impact:
Tmm performance may be degraded.

Workaround:
None

1012009-3 : MQTT Message Routing virtual may result in TMM crash

Links to More Info: BT1012009

Component: Local Traffic Manager

Symptoms:
The BIG-IP system provides an option to use Message Routing virtual servers for MQTT traffic. It uses a different approach to associate a client side and a server side than a standard virtual server. In some instances, a server side is incorrectly handled.

Conditions:
-- A Message Routing virtual with MQTT protocol.
-- A client attempts to reconnect.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None


1011889-6 : The BIG-IP system does not handle DHCPv6 fragmented traffic properly

Links to More Info: BT1011889

Component: Local Traffic Manager

Symptoms:
In the following two scenarios, packets may get dropped by the BIG-IP device.

- [client MTU 1500]<--->(vlan1)<--->[MTU 1500BIG-IP MTU 9000]<--->(vlan2)<--->[MTU 1500server]
If the response from the server is large enough to be fragmented, the BIG-IP system is not able to process the packets.

- [client MTU 1500]<--->(vlan1)<--->[MTU 1500BIG-IP MTU 9000]<--->(vlan2)<--->[MTU 9000server]
Large response coming in a single packet is not fragmented properly on the client-side, then packets may be dropped.

Conditions:
DHCPv6 MTU size is greater than or equal to 1500.

Impact:
Packets are dropped, traffic is disrupted.


1011265-3 : Failover script cannot read /config/partitions/ after upgrade&start;

1011133 : Protocol Inspection compliance check 10208 gtp_disallowed_message_types does not take GTP version into account

Links to More Info: BT1011133

Component: Protocol Inspection

Symptoms:
GTP version 1 and GTP version 2 disagree on message type designations, so blocking a given message type has a different meaning depending on the GTP version.

Conditions:
Compliance check 10208 is configured in an environment where different versions of GTP traffic might be encountered.

Impact:
The device might drop GTP message types that are not intended to be dropped.

Workaround:
If the environment supports/expects only GTP version 1 or version 2 traffic, use compliance check 10223 gtp_disallowed_version to exclude all traffic from the unexpected GTP type to eliminate the message type ambiguity.


1010961-1 : Redirect fails when accessing SAML Resource more than once in SAML IDP initiated Flow

Links to More Info: BT1010961

Component: Access Policy Manager

Symptoms:
In SAML idp initiated Flow, redirects fails on accessing SAML Resource second time as multiple assertions are posted to the SP on same access session

Conditions:
1. BIG-IP SAML SP and IDP configured for IDP initiated Flow
2. Access SAML Resource first time is successful but fails second time for same access session

Impact:
Multiple assertions are sent to SP on same access session and fails to render the backend application second time.

Workaround:
For Access policy contains an allow ending:

when HTTP_REQUEST {
    if { [HTTP::uri] eq "/saml/sp/profile/post/acs" && [ACCESS::session exists -state_allow -sid [ACCESS::session sid]] } {
        HTTP::redirect "/"
    }

1010597-1 : Traffic disruption when virtual server is assigned to a non-default route domain&start;

Links to More Info: BT1010597

Component: Access Policy Manager

Symptoms:
Assigning a virtual server to a non-default route domain might cause a traffic disruption.

Conditions:
-- An APM virtual server is assigned to a route domain other than 0 (zero, the default).
-- An access policy has an agent that results in tmm communicating to the renderer (e.g., Logon agent, HTTP 401 Response agent, and others).

Impact:
Access policy fails.

1010341-4 : Slower REST calls after update for CVE-2021-22986

Links to More Info: BT1010341

Component: TMOS

Symptoms:
As a result of changes were introduced to increase security around the REST API, REST calls that use HTTP basic authentication may take longer to execute that they did previously.

Conditions:
- REST API calls
- HTTP basic authentication used for the REST calls

Impact:
- Degraded performance of the REST API

Workaround:
Update automation scripting to use token based authentication, which is both faster and more secure than HTTP basic authentication


1010209-1 : BIG-IP configuration allows literal CR and LF characters in LTM monitor send and recv strings

Links to More Info: BT1010209

Component: Local Traffic Manager

Symptoms:
It is possible, using REST or tmsh (vi the 'tmsh edit' command) to embed literal carriage return (CR) or line feed (LF) characters in an mcpd object's parameters, rather than the two-byte sequence \r or \n. This can be done with a monitor send or receive string. When the configuration is loaded, the CR characters are stripped off of the strings, resulting in invalid HTTP in the monitor strings.

Conditions:
-- Using HTTP monitors.
-- Embedding literal CR/LF characters in the monitor's send or receive string.

Impact:
Monitors stop working; pool members being monitored are considered inaccessible.

Workaround:
Do not use embedded unprintable characters in monitor send or receive strings.


1009921-3 : 'SSL::verify_result' iRule command may return incorrect value when combined with dynamic CRL check

Links to More Info: BT1009921

Component: Local Traffic Manager

Symptoms:
'SSL::verify_result' iRule command may return '0' (validation check success) even if the client certificate has already been revoked. The expected return value on a revoked certificate is '23' (certificate revoked).

Conditions:
-- Dynamic CRL check is configured on the client SSL profile.

-- An iRule checks client certificate validity by 'SSL::verify_result' command. Here is example.

  when HTTP_REQUEST {
     set cert [SSL::cert 0]
     set cert_string [X509::verify_cert_error_string [SSL::verify_result]]
     set code [SSL::verify_result]
     if { [SSL::verify_result] == 0 }{
        log local0. "success $cert_string $code" return
     }
     else {
        log local0. "failed $cert_string $code" HTTP::respond 403 content "<html>Invalid client certificate:</html>\n" }
  }

Note: SSL::cert command is in fact the trigger for the behavior as it causes a rebuild of the certificate chain and fetches the status from the cache, which is 0. The reason it is 0 in the cache is that, when dynamic CRLs are used, the system verifies the cert, receives a code 23 (revoked), but the system does not update the SSL session cache with the result.

Impact:
The iRule 'SSL::verify_result' command may return unexpected values. Traffic can be unexpectedly load-balanced to the backend pool member when the end user client requests the virtual server with the revoked certificate.

Workaround:
You can use any of the following workarounds:

-- Remove the SSL::cert command from the iRule (it is not needed in HTTP_REQUEST since the system still has the verify result in runtime code).

-- Set cache-size 0 (zero) on client SSL profiles:
# tmsh modify ltm profile client-ssl [client-ssl profile name] cache-size 0

-- Use authentication frequency 'always' on client SSL profiles:
# tmsh modify ltm profile client-ssl [client-ssl profile name] authenticate always

1008233-1 : The gtm_add command fails but reports no error

Links to More Info: BT1008233

Component: Global Traffic Manager (DNS)

Symptoms:
Running the command 'gtm_add' does not add the local GTM to the remote GTM sync group, and it does not display an error message.

Conditions:
The remote GTM has a GTM iRule that references an LTM datagroup that does not exist on the local GTM.

Impact:
The gtm_add command fails silently.

1007909-1 : Tcpdump with :p (peer flow) flag does not capture forwarded between TMMs

Links to More Info: BT1007909

Component: TMOS

Symptoms:
When using tcpdump with the :p flag, it does not capture all packets that are processed by multiple TMMs.

Conditions:
Traffic flows are handled by multiple TMMs, e.g., one of the following:

-- 'preserve strict' set on virtual servers
-- a CMP-demoted virtual server
-- Service Provider (SP) DAG configured, but using custom mappings for some client IP addresses, or some traffic flows using VLANs without SPDAG configured.

Impact:
Causes confusion since there will be packets missing from tcpdump captures.

Workaround:
Use a packet capture filter to capture clientside and serverside flows directly, without relying on the peer flow flag (":p").


1007869-1 : Upgrade from v14.1.x to v15.1.2.1 or later fails for app-tunnel, RDP and config migration&start;

            webtop /Common/test-full-wt-01
        }
    }
}

Conditions:
Upgrade to v15.1.2.1 or later with AppTunnel and RDP resources.

Impact:
The configuration fails to load following the upgrade.

Workaround:
Modify the revision numbers resources, customization path for missing webtop links.

Example:
=======

(1) The following AppTunnel config causes config loading failure:

01070712:3: Failed: name (/Common/Example_resource_app_tunnel_customization) Cache path (/config/filestore/files_d/Common_d/customization_group_d/:Common:Example_resource_app_tunnel_customization_1) does not exist and there is no copy in trash-bin to restore from.

(2) Modify as follows:

In TMSH:
#cp /config/filestore/files_d/Common_d/customization_group_d/\:Common\:Example_resource_app_tunnel_customization_1 /config/filestore/files_d/Common_d/customization_group_d/\:Common\:Example_resource_app_tunnel_customization_2

In bigip.conf under customization configuration:
Rename Example_resource_app_tunnel_customization_1 to Example_resource_app_tunnel_customization_2 (modifying revision numbers from _1 to _2)

#tmsh load sys config

(3) For a missing RDP resource: use VPE to edit access profiles and find the appropriate 'Advanced Resource Assign' agents. Add the appropriate RDP resources in the 'Advanced Resource Assign' agent.

0107176c:3: Invalid Virtual Address, the IP address 10.10.10.20%2 already exists.

Conditions:
-- A partition with a non-default route domain.
-- A virtual server and address list in said partition.
-- Modifying the virtual server to use the address list as its source address.

Impact:
Unable to use a source address list in a partition with a non-default route domain.

Workaround:
Manually create a traffic-matching-criteria object in TMSH with the desired configuration, and then create the virtual server using that traffic-matching-criteria.

1006509-1 : TMM memory leak&start;

Links to More Info: BT1006509

Component: Access Policy Manager

Symptoms:
After upgrading to 15.1.0.4, tmm memory grows and tmm may restart or the BIG-IP system may reboot.

Conditions:
-- APM provisioned
-- Other conditions are unknown but it linked to single sign-on functionality

Impact:
Tmm memory grows and tmm may restart. Traffic disrupted while tmm restarts.


1006449-1 : The default size of the subagent object cache possibly leading to slow snmp response time&start;

Links to More Info: BT1006449

Component: TMOS

Symptoms:
After upgrading from a 13.1.x release to a later release (such as 15.1.x), BIG-IP CPU utilization increases and SNMP is slow to respond.

Conditions:
SNMP client repeatedly polls BIG-IP for OIDs in multiple tables over a short period of time.

Impact:
SNMP queries take an unusually long time to return data, and BIG-IP CPU utilization is higher.

Workaround:
To the file /config/snmp/bigipTrafficMgmt.conf, add one line with the following content:

  cacheObj 16

This could be accomplished by executing the following command line from bash:

  # echo "cacheObj 16" >> /config/snmp/bigipTrafficMgmt.conf

After the above config file has been modified and saved, the "snmpd" daemon must be restarted, using one of two command variants:

  (on a BIG-IP appliance or VE system)

  # bigstart restart snmpd

  (on a a multi-slot VIPRION or vCMP guest)

  # clsh bigstart restart snmpd

(However, this adjustment will be lost when the BIG-IP software is next upgraded.)

1004953-5 : HTTP does not fall back to HTTP/1.1&start;

Links to More Info: BT1004953

Component: Local Traffic Manager

Symptoms:
After upgrading, the BIG-IP system's HTTP profile no longer falls back to HTTP/1.1 if a client sends a corrupted URI.

Conditions:
-- Client sends a corrupted URI (for example a URI containing a space).

Impact:
The BIG-IP system treats the URI as an HTTP/0.9 request (as per RFC) and forwards only the first request line. In previous releases, the BIG-IP system treated the URI as a HTTP/1.1 request.

Workaround:
None.


1004929-1 : During config sync operation, MCPD restarts on secondary blade logging 01020012:3: A unsigned four-byte integer message item is invalid.

Links to More Info: BT1004929

Component: TMOS

Symptoms:
While receiving a config sync operation, mcpd on a secondary blade may restart, logging:

err mcpd[6383]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020012:3: A unsigned four-byte integer message item is invalid.... failed validation with error 16908306

Conditions:
-- A VIPRION system (or cluster-based vCMP guest) with more than one blade processes a full configuration load, i.e. as a result of running "tmsh load sys config" or receiving a full-load config sync from peer BIG-IP.

-- The system generates a large number of warning messages during a configuration load, whose total length is larger than 65,535 bytes.

These warnings can be seen in the output of "tmsh load sys config" or "tmsh load sys config verify", or are logged under message ID 01071859

An example of such a warning is:

SSLv2 is no longer supported and has been removed. The 'sslv2' keyword in the cipher string of the ssl profile (/Common/ssl-profile-1) has been ignored.

Impact:
MCPD on secondary blades restart. Those blades are inoperative while services restart.

Workaround:
Address the warnings reported by the system.


1004845-1 : Accessing attribute using attributeNode value does not work with Portal Access

1004801-2 : In the violation details for Max Parameter Protocol Compliance, the incorrect number of parameters is shown.

Links to More Info: BT1004801

Component: Application Security Manager

Symptoms:
Incorrect number of parameter is shown in the violation details for Max Parameter Protocol Compliance.

Conditions:
Alarm or block flag is enabled on Max Parameter Protocol Compliance violation, and the request contains more than the maximum specified.

Impact:
Request event displays inaccurate number of parameters: the maximum number, plus 1 (e.g., if you specify 7, the maximum shown will be 8).

This occurs because the system stops parsing parameters when the violation is triggered, which occurs when receiving a request with more than the value specified in Max Parameter Protocol. So if you enable the alarm or block flag on requests with 5 parameters, a request with more than 5 parameters will be alarmed/blocked, and the number reported will be 6. If the system receives requests with more than 6 parameters, the number of parameters is still reported as 6.

Workaround:
None

1002417-2 : Switch L2 forwarding entries learnt on multi-blade trunk in one blade needs to be synchronized to other blades of that trunk

Links to More Info: BT1002417

Component: TMOS

Symptoms:
In a chassis, when the switch needs to forward a packet where the destination MAC address does not exist in the L2 forwarding table (DLF, destination lookup failure), the packet is forwarded to blade one and flooded there. This can lead to interfaces on blade one being more heavily used.

Conditions:
Altering of trunk vlan memberships after failovers will lead to traffic imbalance on egress ports.

Impact:
It may lead to an out of bandwidth condition on interfaces.

1000561-5 : HTTP chunked encoding markers incorrectly passed to HTTP/2 client-side

Links to More Info: BT1000561

Component: Local Traffic Manager

Symptoms:
HTTP/2 virtual servers pass the chunk size bytes from the server-side (HTTP/1.1) to the client-side (HTTP/2) when OneConnect and request-logging profiles are applied.

This results in a malformed HTTP response.

Conditions:
-- BIG-IP configured with a HTTP/2 virtual server using OneConnect and request-logging profiles.
-- The pool member sends a chunked response.

Impact:
The HTTP response passed to the client-side includes chunk size header values when it should not, resulting in a malformed HTTP response.

Workaround:
Change HTTP response-chunking to either 'unchunk' or 'rechunk' in the HTTP profile for the virtual server.


1000325-1 : UCS load with 'reset-trust' may not work properly if base configuration fails to load&start;

Links to More Info: BT1000325

Component: TMOS

Symptoms:
When loading a UCS archive using the 'reset-trust' option, if the system fails to load the base configuration from the UCS archive, the system may fail to regenerate new device trust certificates and keys.

This can result in subsequent issues, including configuration load failures after an upgrade, such as:

01070712:3: Values (/Common/dtca.key) specified for trust domain (/Common/Root): foreign key index (key_fk) do not point at an item that exists in the database.
Unexpected Error: Loading configuration process failed.

Conditions:
-- Loading a UCS file using the 'reset-trust' option.
-- The system fails to load the base configuration (bigip_base.conf) in the UCS archive for any reason.
-- The base configuration is corrected, and subsequently loaded (e.g., with 'tmsh load sys config').

Impact:
-- The system does not regenerate critical device trust keys and certificates.
-- After a subsequent upgrade, the BIG-IP system goes to INOPERATIVE state, and reports this error:

01070712:3: Values (/Common/dtca.key) specified for trust domain (/Common/Root): foreign key index (key_fk) do not point at an item that exists in the database.
Unexpected Error: Loading configuration process failed.
