999933-3 : TMM may crash while processing DNS traffic on certain platforms

Links to More Info: K28042514, BT999933

999901-3 : 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:
17.0.0, 16.1.2.2, 15.1.5.1, 14.1.4.6

999881-4 : 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

Fixed Versions:
17.0.0, 16.1.3.1, 15.1.7

999125-2 : 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.

Fix:
Redundant devices remain in the correct failover state following a management IP address change.

Fixed Versions:
17.0.0, 16.1.2.2, 15.1.5.1, 14.1.4.6, 13.1.5

999097-3 : SSL::profile may select profile with outdated configuration

Links to More Info: BT999097

Component: Local Traffic Manager

Symptoms:
Under some circumstances, an iRule-selected SSL profile may a send previously configured certificate to the peer.

Conditions:
iRule command SSL::profile is used to select a profile that is not attached to the virtual server, and changes have been made in the profile's cert-key-chain field.

Impact:
The TLS client may receive an outdated certificate that does not match with the current configuration, potentially leading to handshake failures.

Workaround:
Avoid making changes to a profile that is actively being used by the iRule command.

Fix:
The system now makes sure that SSL profiles are properly reloaded after changes are made.

Fixed Versions:
17.0.0, 16.1.2.1, 15.1.5, 14.1.4.5

998473-2 : NTLM Authentication fails with 'RPC Fault received' error and return code: 0xc0000001 (STATUS_UNSUCCESSFUL)

Links to More Info: BT998473

Component: Access Policy Manager

Symptoms:
NTLM Authentication fails with 'RPC Fault received' error and return code: 0xc0000001 (STATUS_UNSUCCESSFUL)

Conditions:
1. NTLM front-end authentication is enabled.
2. Active Directory users are subscribed to more than one hundred groups.

Impact:
NTLM authentication for Active Directory users which are subscribed to more than hundred groups will fail.

Workaround:
None

Fix:
A fix has been provided to the sequence number handling which is used to calculate the RPC checksum as part of ID 949477.

998221-3 : Accessing pool members from configuration utility is slow with large config

Links to More Info: BT998221

Component: TMOS

Symptoms:
Accessing the pool members page from the BIG-IP Configuration Utility/GUI is slow compared with accessing Pool members from TMSH/CLI.

Conditions:
-- Accessing pool member information through the BIG-IP configuration utility.
-- Thousands of pools and pool members in the configuration.

Impact:
In the GUI, it takes approximately 20-30 seconds, whereas the CLI returns results in less than 1 second,

Managing pool members from configuration utility is very slow causing performance impact.

Workaround:
None

Fix:
Optimized the GUI query used for retrieving pool members data.

Fixed Versions:
17.0.0, 16.1.2, 16.0.1.2, 15.1.4, 14.1.4.3

998085-1 : BIG-IP DataSafe GUI does not save changes

Component: Fraud Protection Services

Symptoms:
Due to a JavaScript error, the BIG-IP DataSafe GUI does not save changes.

Conditions:
-- Provision FPS.
-- License DataSafe.
-- Configure the system using the GUI.

Impact:
Configurations made for DataSafe using the BIG-IP Configuration Utility GUI cannot be saved.

Workaround:
Use tmsh to configure the BIG-IP system.

Fix:
BIG-IP DataSafe GUI is working properly and configurations are now saved.

Fixed Versions:
16.1.0, 15.1.3

997929-3 : Changing a Traffic Matching Criteria port from 'any' to another value can prevent a virtual server from processing traffic

Links to More Info: BT997929

Component: Local Traffic Manager

Symptoms:
If a virtual server is using a traffic-matching-criteria (TMC) with a destination-inline-port of zero ('any'), and this is later changed (either to a non-zero port value, or to a port-list with non-zero port values) the virtual server stops processing traffic.

If tmm is restarted (which causes an outage) the virtual server resumes accepting traffic using the new ports. In addition, changing the virtual server's port back to 'any' also causes traffic processing to resume.

Conditions:
-- A virtual server using an address list for its destination, and 'any' (zero) for its destination port.

-- Changing the virtual server's destination port to a non-zero value, or to a port-list with non-zero port values.

Impact:
The virtual server stops processing traffic.

Workaround:
To recover, you can do either of the following:

-- Restart tmm:
bigstart restart tmm

-- Change the virtual server's port back to 'any' (0).

Fixed Versions:
16.1.0, 16.0.1.2, 15.1.4, 14.1.4.4

997761-2 : Subsessionlist entries leak if there is no RADIUS accounting agent in policy

Links to More Info: BT997761

Component: Access Policy Manager

Symptoms:
Subsessionlist entries are not cleaned up when subsessions are deleted. For long-lived main sessions, use cases such as API protection, the number of leaked subsessionlist entries increases over time, resulting in increasing memory consumption. If high availability (HA) is configured, the standby device can experience even more memory pressure when a very large number of subsessionlist entries are sent to it for mirroring.

Conditions:
This issue occurs if the main session is long-lived and there is no RADIUS accounting agent in the policy.

Impact:
TMM may run out of memory and restart. Traffic disrupted while tmm restarts.

Workaround:
None

Fixed Versions:
16.1.0, 15.1.5

997641 : APM policy ending with redirection results in policy execution failure

Links to More Info: BT997641

Component: Access Policy Manager

Symptoms:

997313-3 : Unable to create APM policies in a sync-only folder★

Links to More Info: BT997313

Component: TMOS

Symptoms:
Unable to configure an APM policy in a sync-only folder, or the configuration fails to load after an upgrade, with an error message similar to:

-- err mcpd[mcpd_pid]: 01070734:3: Configuration error: Invalid Devicegroup Reference. The customization_group (/Common/sync-only/example_apm_customization) requires customization_source (/Common/standard) to be syncd to the same devices

Conditions:
-- Multiple BIG-IP devices configured in a sync-only device group, but different/non-overlapping failover device groups
-- APM policy being created in a folder or partition associated with sync-only device group.

Impact:
-- Unable to create the access policy.
-- The configuration fails to load and the device remains inoperative.

Workaround:
You can use either of the following strategies to prevent the issue:

--Do not create APM policies in a sync-only folder.

--Disable MCPD device-group reference validation for the sync-only folder, e.g.:
tmsh modify sys folder /Common/sync-only no-ref-check true

987341-2 : BIG-IP OpenID Connect Discovery process does not support strong TLS ciphers.

Links to More Info: BT987341

Component: Access Policy Manager

Symptoms:
BIG-IP discovers and updates JSON Web Keys (JWK) in OpenID Connect (OIDC) deployments using a Java Runtime Environment (JRE). The JRE in BIG-IP does not support strong TLS ciphers, so the discovery/update process can fail against OIDC providers that enforce strong encryption requirements.

Conditions:
Using an OpenID Connect provider that allows only strong TLS ciphers. and using an APM configuration that validates incoming JWTs against a dynamic JWK list in Internal Validation Mode.

Impact:
This might cause discovery to fail against certain OpenID Connect auth providers that enforce strong cipher requirements. It could lead to JWT validation failure as the JWK expire and cannot be updated by BIG-IP.

Conditions:
Encapsulated dest-mac is not equal to the Generic Routing Encapsulation (GRE) tunnel mac-address.

Impact:
Virtual server is not collecting decapsulated packets from the GRE Transparent Bridge tunnel unless the dest-mac of the encapsulated packet is the same as the mac-address of the GRE tunnel.

Workaround:
None

Fix:
Added a new DB key 'iptunnel.mac_overwrite'. This DB key defaults to 'disable'.

Set the DB key to 'enable' to cause the BIG-IP system to overwrite the destination MAC of the encapsulated traffic:

tmsh modify sys db iptunnel.mac_overwrite value enable
tmsh save sys config

This allows virtual servers on the BIG-IP system to process traffic.

Behavior Change:
Added a new DB key 'iptunnel.mac_overwrite'. This DB key defaults to 'disable'.

To cause the BIG-IP system to overwrite the destination MAC of the encapsulated traffic, set the DB key to 'enable' and save the config:

tmsh modify sys db iptunnel.mac_overwrite value enable
tmsh save sys config

This allows virtual servers on the BIG-IP system to process traffic.

980821-2 : Traffic is processed by All Port Virtual Server instead of Specific Virtual Server that is configured.

Links to More Info: BT980821

Component: Local Traffic Manager

Symptoms:
Traffic is directed to a virtual server that is configured with port any even though there is a virtual server with a specific port that the traffic should match.

Conditions:
There are two virtual servers configured:
- One with a specific port and ip-protocol 'any'
- One with port any and a specific ip-protocol

Impact:
Traffic destined to the port matches the any-port virtual server rather than the specific port virtual server.

Workaround:
Create individual listeners for specific protocols.

For example, given the configuration:
  ltm virtual vs-port80-protoAny {
    destination 10.1.1.1:80
    ip-protocol any
    ...
  }
  ltm virtual vs-portAny-protoTCP {
    destination 10.1.1.1:0
    ip-protocol TCP
    ...
  }

Replace the vs-port80-protoAny with virtual servers configured for the specific protocols desired:
  ltm virtual vs-port80-protoTCP {
    destination 10.1.1.1:80
    ip-protocol TCP
    ...
  }
  ltm virtual vs-port80-protoUDP {
    destination 10.1.1.1:80
    ip-protcol UDP
    ...
  }

Fix:
More specific virtual server now gets more priority than wildcard virtual server to process traffic.

971217-2 : AFM HTTP security profiles may treat POST requests with Content-Length: 0 as "Unparsable Request Content" violations.

Links to More Info: BT971217

Component: Local Traffic Manager

Symptoms:
An HTTP Security profile can be created and enabled within Advanced Firewall Manager's Protocol Security options. The HTTP Security Profile contains various protocol checks that can be enabled and disabled to allow customization of security checks. When the "Unparsable request content" check is selected, BIG-IP will incorrectly indicate that HTTP POST requests with Content-Length:0 are not allowed assuming that these requests are unparsable. POST requests with Content-Length:0 can still be checked by enabling the "POST request with Content-Length: 0" option in the same profile.

Conditions:
-- HTTP Protocol Security Profile configured with the "Unparsable request content" check.

-- Client sends HTTP POST request with Content-Length:0

Impact:
POST requests of Content-Length 0 cannot be disabled separately from general "Unparsable request content".

Workaround:
None.

Fix:
POST requests containing a Content-Length: 0 header are no longer considered as "Unparsable Request Content" violations and will not incorrectly be reported.

Behavior Change:
POST requests containing a Content-Length: 0 header are no longer considered as "Unparsable Request Content" violations within the AFM HTTP protocol security profile.

969105-2 : HA failover connections via the management address do not work on vCMP guests running on VIPRION

Links to More Info: BT969105

Component: TMOS

Symptoms:
A high availability (HA) failover connection using the management IP addresses does not work on vCMP guests running on a VIPRION device.

BIG-IP instances running directly on hardware, on Virtual Edition, and as vCMP guests running on an appliance are unaffected.

HA failover connections using self IPs are unaffected.

Conditions:
-- vCMP guest running on a VIPRION device
-- high availability (HA) failover connection using the management IP addresses (unicast and/or multicast)

Impact:
Failover state determination over the management port is permanently down.

Workaround:
While self IP-based high availability (HA) failover connections are not affected by this issue, F5 recommends configuring failover connections over both management IPs and self IPs (as detailed in K37361453: Configuring network failover for redundant VIPRION systems :: https://support.f5.com/csp/article/K37361453).

To mitigate this issue, run the following command on each blade of every guest:
touch /var/run/chmand.pid

The workaround does not survive a reboot, so a more permanent workaround is to edit the file /config/startup and add a line to touch /var/run/chmand.pid.

Add this line to the end of /config/startup:

(sleep 120; touch /var/run/chmand.pid) &

Note: The sleep time of 120 seconds should be tested as it depends on how quickly or slowly the Guest starts up, so the appropriate value for one system may differ from another system.

Alternatively, You can use instructions in K11948: Configuring the BIG-IP system to run commands or scripts upon system startup :: https://support.f5.com/csp/article/K11948 to issue commands at system startup after verification if mcpd is up and ready, e.g.:

#!/bin/bash
source /usr/lib/bigstart/bigip-ready-functions
wait_bigip_ready

# Customized startup command(s) can be added below this line.
touch /var/run/chmand.pid
# Customized startup command(s) should end above this line.

967249-2 : TMM may leak memory early during its startup process, and may continue to do so indefinitely.

Links to More Info: BT967249

Component: Local Traffic Manager

Symptoms:
TMM leaks memory in the packet and xdata components. The aggressiveness of the leak depends on how much traffic TMM receives from the Linux host subsystem.

Conditions:
- A BIG-IP system running more than 1 TMM instance.

- Early during its startup process, TMM begins receiving traffic from the Linux host subsystem destined to the network (e.g., remote syslog traffic routed to its destination through TMM).

- Depending on the system's configuration, TMM attempts to set up flow forwarding for the aforementioned traffic. This may happen, for instance, if the egress VLAN is configured for 'cmp-hash src-ip'.

- TMM hasn't fully completed its startup process yet.

Impact:
TMM leaks memory.

If the flow set up during early TMM startup continues to receive a constant stream of new packets, then the flow may live on indefinitely, and TMM may continue to leak memory indefinitely.

In the example of remote syslog traffic, this could happen, for instance, if the box keeps logging messages at a sustained rate.

Eventually, TMM may be unable to allocate any more memory and crash. Traffic disrupted while tmm restarts.

Workaround:
You can work around this issue by ensuring that TMM does not receive any traffic from the Linux host subsystem for forwarding during early startup.

In the example of remote syslog destinations, you could specify the management IP address of the system as the source IP address for the traffic, thus forcing the traffic out of the management port instead of TMM. This implies the management port has a suitable working route to the destination.

967093-1 : In SSL forward proxy when the signing CA cert and end-entity cert has a different signature algorithm, the SSL connection may fail

Links to More Info: BT967093

Component: Local Traffic Manager

Symptoms:
In SSL forward proxy, the client side handshake may fail with the message: fwdp lookup error.

Conditions:
The handshake failure occurs when the certificate chain consists of different key types. For example, the following cert chain may fail the handshake:

root CA (rsa) --> intermediate CA1 (rsa) --> intermediate CA2 (ec) --> end-entity cert (ec)

The signing CA which is intermediate CA2 has a key of EC type, but cert is signed by RSA signature. The end-entity cert has a key of EC type, but cert is signed by ECDSA.
In this case, the signer cert has different signature from that of the end-entity cert.

Impact:
SSL forward proxy handshake fails.

Fix:
Fixed an issue with SSL forward handshakes.

<...> systemd[1]: tpm-status-check.service failed.

However, checking the System Integrity Status using the 'tpm-status' or 'tmsh run sys integrity status-check' command shows 'System Integrity Status: Valid'.

Conditions:
This may occur under the following conditions:

-- Running BIG-IP v14.1.0 or later.
-- Using Engineering Hotfixes containing fixes for the following bugs:
   - ID893885 (https://cdn.f5.com/product/bugtracker/ID893885.html)
   - ID946745 (https://cdn.f5.com/product/bugtracker/ID946745.html)
-- Using hardware platforms that include a Trusted Platform Module (TPM), including:

   - VIPRION B4450 blades

Impact:
The tpm-status-check service inaccurately indicates that the System Integrity Status is not Valid.

This is incorrect, and conflicts with the accurate System Integrity Status provided by the 'tpm-status' utility and 'tmsh run sys integrity status-check' command.

Workaround:
To observe the correct System Integrity Status, do either of the following:
-- Use the 'tpm-status' utility.
-- Run the command:
tmsh run sys integrity status-check

Fix:
This incorrect status reporting has been corrected.

962817-2 : Description field of a JSON policy overwrites policy templates description

Links to More Info: BT962817

Component: Application Security Manager

Symptoms:
Creating a UTF-8 policy using a template for the first time creates a binary policy the system uses the next time you create a UTF-8 policy with the same template.

If the creation occurs via JSON policy import, the description field of the JSON policy overwrites the description from the template, and the next time you create a UTF-8 policy using the same template, the system uses the description from the first JSON policy.

Conditions:
Create an initial UTF-8 policy with some template using a JSON policy with a custom description.

Impact:
The next time you create a UTF-8 policy with the same template, unless you provide a description, the system uses the one from the initially created JSON policy instead the template.

Workaround:
Before creating the second policy, remove the binary file that was created from the first run. For example if the template used was Fundamental:

rm -f /ts/install/policy_templates/fundamental.bin

Fix:
The binary file now contains the correct description.

962589-2 : 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.

960749-2 : TMM may crash when handling 'DNS Cache' or 'Network DNS Resolver' traffic

Links to More Info: BT960749

Component: Global Traffic Manager (DNS)

Symptoms:
TMM crashes, dumps a core file, and restarts.

Conditions:
-- The configuration includes one or more 'DNS Cache' or 'Network DNS Resolver' objects.

-- The DNS Cache or Network DNS Resolver objects receive traffic.

Impact:
Traffic disrupted while tmm restarts. A redundant unit will fail over.

Fix:
TMM no longer crashes when 'DNS Cache' or 'Network DNS Resolver' objects handle traffic.

Fixed Versions:
16.1.0, 16.0.1.1, 15.1.3, 14.1.4, 13.1.3.5, 12.1.6, 11.6.5.3

960437-2 : The BIG-IP system may initially fail to resolve some DNS queries

Links to More Info: BT960437

Component: Global Traffic Manager (DNS)

Symptoms:
Configurations that use a 'DNS Cache' or 'Network DNS Resolver' are affected by an issue whereby the system may initially fail to resolve some DNS queries.

Subsequent queries for the same domain name, however, work as expected.

Only some domain names are affected.

Conditions:
- The BIG-IP system is configured with either a DNS Cache or Network DNS Resolver.

- The cache is still empty in regard to the domain name being resolved (for example, TMM has just started).

- The cache configuration specifies 'Use IPv6' (the default) but the system has no IPv6 default route.

Impact:
Initial DNS resolution of some domain names fails. Regardless of whether this happens via a DNS cache or Network DNS Resolver, the failure is returned to the client.

In the case of a DNS Cache, the client may just be returned with no record. In the case of a Network DNS Resolver, the failure will depend on the feature using the resolver.

For instance, SWG, SSL Orchestrator, or the HTTP Explicit Forward Proxy, in general, are examples of features that rely on a Network DNS Resolver. In this case, the client's browser will fail to connect to the requested destination, and the client will be shown a proxy error.

Workaround:
Disable 'Use IPv6' in the affected DNS Cache or Network DNS Resolver.

1a. Go to DNS :: Caches :: Cache list.
OR
1b. Go to Network :: DNS Resolvers :: DNS Resolver list.
2. Select the item you want to update in the list.
3. Uncheck 'Use IPv6'
4, Select Update.

You can keep the object in this state (with no consequences) until you define an IPv6 default route on the system, and you wish for the system to also use IPv6 to connect to Internet name-servers.

Fix:
DNS resolution works as expected, with domains resolving the first time they are queried.

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.

Impact:
HTTPS monitor shows pool members or nodes down when they are up.

Workaround:
Restart bigd or remove and add monitors.

Fix:
In case of handshake failure, BIG-IP will try TLS 1.2 version.

953393-2 : TMM crashes when performing iterative DNS resolutions.

Links to More Info: BT953393

Component: Global Traffic Manager (DNS)

Symptoms:
TMM crashes and produces a core file.

Conditions:
The BIG-IP system configuration includes a Network DNS Resolver, which is referenced by another object (for example, a HTTP Explicit Forward Proxy profile) for DNS resolution.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
You may be able to work around this issue by having the Network DNS Resolver work in forwarding/recursive mode rather than in resolving/iterative mode.

To do so, you configure a Forward Zone in the Network DNS Resolver for '.' (the DNS root). This causes DNS to send all DNS requests to a different, external resolver of your choice, which will perform recursive resolution.

The servers you configure for the '.' Forward Zone could be resolvers internal to your organization or public resolvers (e.g. Google DNS).

Fix:
TMM no longer crashes.

950849-4 : B4450N blades report page allocation failure.★

Links to More Info: BT950849

Component: TMOS

Symptoms:
Despite having free memory, the BIG-IP system frequently logs kernel page allocation failures on B4450N blades to the /var/log/kern.log file like the following:

swapper/16: page allocation failure: order:2, mode:0x104020

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

Conditions:
This occurs on B4450N blades regardless of configuration.

Impact:
As different processes can experience this issue, the system may behave unpredictably. For example, it is possible for a TMOS installation to fail as a result of this issue. Other processes may not exhibit any side effect as a result of this issue. The exact impact depends on which process becomes affected and how this process is designed to handle such a failure to allocate memory.

Workaround:
You must perform the workaround on each blade installed in the system.

-- 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 VIPRION system.

2) Run the following commands:

# clsh "sysctl -w vm.min_free_kbytes=131072"
# clsh "echo -e '\n# Workaround for ID950849' >> /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 VIPRION 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 ID950849' >> /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 all blades 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 primary blade only, 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 kernel page allocation failures on B4450 (A114) blades.

When attempting to use zonerunner to edit a TXT record that contains a plus character, BIG-IP DNS presents the error message 'Resolver returned no such record'.

Conditions:
A TXT record exists with RDATA (the value of the TXT record) containing one or more + symbols

Impact:
Unable to edit the record.

Workaround:

949721-2 : QUIC does not send control frames in PTO packets

Links to More Info: BT949721

Component: Local Traffic Manager

Symptoms:
When the QUIC PTO timer fires, it may resend some in-flight data. That data will not include any in-flight control frames.

Conditions:
A control frame is in-flight when the PTO timer fires.

Impact:
Minimal. The PTO timer is a mechanism to 'get ahead' of any lost packets and if a packet containing control frames is lost, those frames will be retransmitted.

Workaround:
None.

Fix:
Retransmittable control frames are now sent when the PTO timer fires.

949593-3 : Unable to load config if AVR widgets were created under '[All]' partition★

Links to More Info: BT949593

Component: Application Visibility and Reporting

Symptoms:
When upgrading to or loading saved configuration on BIG-IP software v13.0.0 or later, if the configuration contains AVR widgets created under a partition of '[All]', the config load fails.

Conditions:
This occurs if one or more AVR widgets in the configuration was created under the read-only '[All]' pseudo-partition.
This could have occurred if you were running a version of BIG-IP which did not include the fix for ID 721408.

Impact:
Upgrading to or loading an affected configuration on BIG-IP v13.x or later fails.

Workaround:
Manually edit the /config/bigip.conf configuration file and change '[All]' to 'Common':

# sed -i 's/\\\[All\]/Common/g' /config/bigip.conf
# tmsh load sys config
# tmsh save sys config

This should be done before upgrading to BIG-IP v13.x or later, or before saving configuration to be loaded later, or before loading a saved configuration from the config files.

Fix:
It is possible to successfully upgrade from or load a configuration containing one or more AVR widgets created under the read-only '\[All]' pseudo-partition or under other not existing partitions. With the current fix all partitions are changed to "Common" during upgrade.

Fixed Versions:
17.0.0, 16.0.1.2, 15.1.3, 14.1.4, 13.1.4

949477-1 : NTLM RPC exception: Failed to verify checksum of the packet

Links to More Info: BT949477

-- Configure NTLM front-end authentication.

Impact:
User authentication fails.

Workaround:
1. Run the 'nlad' process with '-encrypt no' in the file /etc/bigstart/startup/nlad.

2. Disable encryption for nlad:
   # vim /etc/bigstart/startup/nlad

   change:

949145-5 : Improve TCP's response to partial ACKs during loss recovery

Links to More Info: BT949145

Component: Local Traffic Manager

Symptoms:
- A bursty retransmission occurs during TCP's loss recovery period.

Conditions:
- TCP filter is used.
- TCP stack is used instead of TCP4 stack (based on profile settings).
- Packet loss occurs during the data transfer and TCP's loss recovery takes place.

Impact:
The bursty retransmissions may lead to more data getting lost due to large amount of data being injected into the network.

Workaround:
In versions prior to v16.0.0, use a TCP profile which selects the TCP4 stack instead of the TCP stack. There is no workaround for version 16.0.0.

Fix:
Partial ACK handling during loss recovery is improved.

Fixed Versions:
16.1.0, 16.0.1.1, 15.1.2, 14.1.3.1, 13.1.3.6, 12.1.5.3, 11.6.5.3

948985-2 : Workaround to address Nitrox 3 compression engine hang

Links to More Info: BT948985

Component: Local Traffic Manager

Symptoms:
Occasionally the Nitrox3 compression engine hangs.

In /var/log/ltm:

crit tmm[12404]: 01010025:2: Device error: n3-compress0 Nitrox 3, Hang Detected: compression device was reset (pci 02:00.1, discarded 1).
crit tmm[12404]: 01010025:2: Device error: n3-compress0 Zip engine ctx eviction (comp_code=0): ctx dropped.

Conditions:
The BIG-IP system uses Nitrox 3 hardware compression chips: 5xxx, 7xxx, 12250, and B2250.

You can check if your platform has nitrox3 by running the following command:

tmctl -w 200 compress -s provider

provider
--------
bzip2
lzo
nitrox3 <--------
zlib

Impact:
The Nitrox3 hardware compression system becomes unavailable, and the compression mode switches to software compression. This can lead to high CPU usage.

Workaround:
Disable HTTP compression or use software compression.

Fix:
Added db key compression.nitrox3.dispatchsize to control the request size.

Links to More Info: BT948757

Component: Local Traffic Manager

Symptoms:
A snat-translation address with ARP enabled responds to ARP requests but not ICMP ECHO requests.

Conditions:
A snat-translation address is configured with ARP enabled.

Impact:
Application traffic should not be impacted, as external hosts trying to resolve the snat-translation and return traffic to it should still be able to do so; however, ping is an important network troubleshooting tool, and not being able to ping the address may create confusion.

Workaround:
None.

Fix:
A snat-translation now correctly responds to both ARP requests and ICMP ECHO requests.

948717-3 : F5-pf_daemon_cond_restart uses excessive CPU★

Links to More Info: BT948717

Component: TMOS

Symptoms:
The script /etc/init.d/f5-pf_daemon_cond_restart spawns a lot of ephemeral processes that collectively use about 10-15% of a core, regardless of the number of cores.

This is contributing to higher CPU usage after upgrading from an earlier version

Conditions:
On upgrade to a 15.1.x version, high CPU usage is observed.

Impact:
Higher CPU utilization on control plane, typically the equivalent of about 10-15% (of one core) extra.

Workaround:
None.

- Cloud Failover Extension unexpected behavior (where applicable)

Conditions:
- BIG-IP Azure Virtual Edition
- Azure Host performs a Network Management Agent (NMAgent) update while TMM is running
- BIG-IP VE using Accelerated Networking

Impact:
- Traffic disrupted while tmm restarts
- BIG-IP restarts
- Cloud Failover Extension state data lost (where applicable)

Workaround:
- Disable Accelerated Networking on BIG-IP network interfaces (Reversed settings from Azure documentation)

     Individual VMs & VMs in an availability set
     First stop/deallocate the VM or, if an Availability Set, all the VMs in the Set:
           Azure CLI
                az vm deallocate \
                --resource-group myResourceGroup \
                --name myVM
    Important, please note, if your VM was created individually, without an availability set, you only need to stop/deallocate
    the individual VM to disable Accelerated Networking. If your VM was created with an availability set, all VMs contained in
    the availability set will need to be stopped/deallocated before disabling Accelerated Networking on any of the NICs.

    Once stopped, disable Accelerated Networking on the NIC of your VM:
           Azure CLI
                az network nic update \
                --name myNic \
                --resource-group myResourceGroup \
                --accelerated-networking false
    Restart your VM or, if in an Availability Set, all the VMs in the Set and confirm that Accelerated Networking is disabled:
           Azure CLI
                az vm start --resource-group myResourceGroup \
                --name myVM

948241-2 : Count Stateful anomalies based only on Device ID

Links to More Info: BT948241

Component: Application Security Manager

Symptoms:
Currently when Device ID is enabled, the BIG-IP system counts stateful anomalies on both IP and Device ID. When a client has a proxy (without XFF), and many requests arrive with the same IP, this can cause false positives

Conditions:
- Bot Defense profile is attached to a virtual server.
- Bot Defense profile has "Browser Verification" set to "Verify After Access" or "Device ID Mode" set to "Generate After Access".

Impact:
False positives may occur in case of a proxy without XFF

Workaround:
None

Fix:
Stateful anomalies are no longer counted on IP when Device ID is enabled

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

------------
  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'.

943577-2 : 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>

942549-2 : Dataplane INOPERABLE - Only 7 HSBs found. Expected 8

Links to More Info: BT942549

Component: TMOS

Symptoms:
During boot of a i15xxx system you see the message:

Dataplane INOPERABLE - Only 7 HSBs found. Expected 8

Conditions:
This issue can occur on any i15xxx device, although some devices exhibit the failure consistently and others never exhibit the issue.

Impact:
When this failure occurs in a system, the system is inoperable.

Workaround:
In order to workaround this issue, the system must be updated to install a script that is capable of resetting the hardware device during the HSB load process.

If it's not possible to install an EHF with the updated script or a version of BIG-IP with the fix, then it can be installed manually by providing the fw_update_post.init file and replacing it in /etc/init.d/fw_update_post. It is recommended that the existing fw_update_post is backed-up and this is only done in cases where the EHF or a fixed version of BIG-IP cannot be installed.

Fix:
A 'Dataplane INOPERABLE - Only 7 HSBs found. Expected 8' condition caused by a PCIE linking failure is resolved by an updated HSB load script which correctly resets BIG-IP i15xxx system hardware during boot.

Persistent 'Dataplane INOPERABLE' messages, after this fix is installed, indicate an unrelated failure.

940209 : Chunked responses with congested client connection may result in server-side TCP connections hanging until timeout.

Links to More Info: BT940209

Component: Local Traffic Manager

Symptoms:
When an HTTP/2 profile is configured on the client side, chunked responses are always sent unchunked. When a connection to a client is congested, the BIG-IP system may not properly close established server-side connections causing subsequent HTTP/2 requests to stall.

Conditions:
-- A virtual server with an HTTP/2 profile configured on the client side.
-- A server responds with a chunked response.

Impact:
HTTP/2 requests intermittently stall due to the existing server-side TCP connection remaining open.

Workaround:
Configure an HTTP profile on the client side with a value of 'unchunk' on the response-chunking option.

Fix:
HTTP/2 requests no longer stall, as the server side TCP connection is properly closed.

940021-3 : Syslog-ng hang may lead to unexpected reboot

Links to More Info: BT940021

Component: TMOS

Symptoms:
A syslog-ng issue with remote logging to an invalid remote syslog server may lead to unexpected reboot.

The BIG-IP may unexpectedly reboot after a host watchdog timeout when syslog-ng gets hung up.

Logs via syslog-ng are no longer written, though logging not via syslog-ng continues unaffected.
This 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 (just one core equivalent, not all CPU capacity on system).

Typically things appear fine on rest of system - there will usually be adequate CPU and memory.
Hours or days later graphs will have a gap of usually tens of minutes to hours before an unexpected reboot.

Post reboot logs (in /var/log/sel for iSeries or ltm log otherwise) show this is a host watchdog reboot.
After reboot the system runs correctly, though if the syslog-ng remote server was invalid this remains the case.

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.

  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.

Fix:
Fixed an issue with syslog-ng hang occasionally causing a system restart.

This fix is not a complete fix. You will still need to remove unused syslog-ng servers from the BIG-IP configuration.

939877-1 : 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.

939529-2 : Branch parameter not parsed properly when topmost via header received with comma separated values

Links to More Info: BT939529

Component: Service Provider

Symptoms:
MRF SIP in LoadBalancing Operation Mode inserts a VIA header to SIP request messages. This Via header is removed from the returned response message. The VIA header contains encrypted routing information to route the response message. The SIP specification states that INVITE/CANCEL messages in a dialogue should contain the same branch header. The code used to encrypt the branch field returns a different branch ID for INVITE and CANCEL messages.

Conditions:
-- Enabling SIP Via header insertion on the BIG-IP system.
-- SIP MRF profile.
-- Need to cancel an INVITE.
-- INVITE Via header received with multiple comma-separated values.

Impact:
Some SIP clients have code to verify the branch fields in the Via header. These clients expect the branch to be same for INVITE and CANCEL in a dialogue. Because the branch received is different, these clients are unable to identify the specific INVITE transaction. CANCEL is received and client sends a 481 error:

SIP/2.0 481 Call/Transaction Does Not Exist.

Workaround:
Use iRules to remove the topmost Via header and add new a new Via header that uses the same branch as INVITE and CANCEL while sending messages to SIP clients.

Fix:
The BIG-IP system now ensures the branch field inserted in the via header same for INVITE and CANCEL messages.

936557-2 : Retransmissions of the initial SYN segment on the BIG-IP system's server-side incorrectly use a non-zero acknowledgement number when Verified Accept is enabled.

Links to More Info: BT936557

Component: Local Traffic Manager

Symptoms:
As the BIG-IP system attempts to open a TCP connection to a server-side object (e.g., a pool member), retransmissions of the initial SYN segment incorrectly use a non-zero acknowledgement number.

Conditions:
This issue occurs when the following conditions are true:

-- Standard TCP virtual server.

-- TCP profile with Verified Accept enabled.

-- Receipt of the client's ACK (as part of the client-side TCP 3-way handshake) is delayed. Due to Verified Accept being enabled, this delay causes the BIG-IP system to retransmit its SYN to the server until the client's ACK is received.

Impact:
Depending on the specific server implementation, or the security devices present on the BIG-IP system's server-side before the server, a SYN containing a non-zero acknowledgement number may be rejected. In turn, this may cause connections to fail to establish.

Workaround:
If compatible with your application and specific needs, you can work around this issue by disabling Verified Accept in the TCP profile.

Fix:
SYN segment retransmissions now correctly use 0 as the acknowledgement number.

935801-4 : HSB diagnostics are not provided under certain types of failures

Links to More Info: BT935801

Component: TMOS

Symptoms:
In rare cases where the HSB detects an error and triggers a high-availability (HA) failover, HSB-specific diagnostic data is not provided.

An example are XLMAC errors, which can be seen in the TMM logs:

<13> Jul 25 18:49:41 notice The number of the HSB XLMAC recovery operation 11 or fcs failover count 0 reached threshold 11 on bus: 3.
<13> Jul 25 18:49:41 notice high availability (HA) failover action is triggered due to XLMAC/FCS erros on HSB1 on bus 3.

Conditions:
The HSB detects an internal error.

Impact:
There is less HSB data for analysis when an internal HSB occurs.

Workaround:
None.

Fix:
Dump HSB registers on all HSB-initiated high-availability (HA) failovers.

935593-4 : Incorrect SYN re-transmission handling with FastL4 timestamp rewrite

Links to More Info: BT935593

Component: Local Traffic Manager

Symptoms:
FastL4 profiles configured with the TCP timestamp rewrite option enabled does not treat retransmitted SYNs in a correct manner.

Conditions:
FastL4 profile with TCP timestamp rewrite option is in use.

Impact:
Timestamp on some TCP packets sent by BIG-IP systems might be incorrect.

Workaround:
Do not use TCP timestamp rewrite.

935293-2 : 'Detected Violation' Field for event logs not showing

Links to More Info: BT935293

Component: Application Security Manager

Symptoms:
Violation is missing/details not populated in the event log page, when a POST request with large number of parameters are sent to the BIG IP system.

Conditions:
-- A large POST request with lots of parameters is sent to BIG-IP system.
-- 'Learn New Parameters' is enabled.

Impact:
You cannot see the violation details.

Workaround:
Disabling parameter learning helps.

Note: This happens only with a large number of parameters. Usually it works as expected.

Fix:
The eventlog is reserving space for violations.

16.1.0, 16.0.1.1, 15.1.3, 14.1.4, 13.1.3.5

935249-2 : 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.

17.0.0, 16.1.2.1, 15.1.5

935177-2 : 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:
17.0.0, 16.1.2.2, 15.1.6.1

935029-3 : TMM may crash while processing IPv6 NAT traffic

934993-2 : BIG-IP resets HTTP/2 connections when a peer exceeds a number of concurrent streams

Links to More Info: BT934993

Component: Local Traffic Manager

Symptoms:
The HTTP/2 protocol allows informing a peer about the number of concurrent streams it is allowed to have. When this number is exceeded, the RFC stipulates that the system must serve all open streams and then terminate a connection.

Conditions:
-- The BIG-IP system has a virtual server with an HTTP/2 profile configured on the client side.
-- A client opens more streams than a configured value for concurrent-streams-per-connection in HTTP/2 profile.

Impact:
BIG-IP resets a connection and a client (browser) does not receive any response for outstanding requests. It requires manually reload of the webpage to address the issue.

Workaround:
None.

Fix:
When a peer exceeds a number of concurrent streams allowed by BIG-IP systems, it sends GOAWAY with a REFUSED_STREAM error code and allows graceful completion of all open streams, and then terminates the connection.

Fixed Versions:
16.1.0, 16.0.1.1, 15.1.2

934941-2 : Platform FIPS power-up self test failures not logged to console

Links to More Info: BT934941

Component: TMOS

Symptoms:
The BIG-IP system does not log FIPS power-up self-test failures to the console.

Conditions:
A FIPS failure occurs during the power-up self test.

Impact:
Platform FIPS failures are made more difficult to identify and diagnose, because the system console fails to include anything at all that indicates a failure.

Workaround:
None.

Fixed Versions:
16.1.0, 15.1.3, 14.1.3.1

934721-2 : TMM core due to wrong assert

Links to More Info: BT934721

Component: Application Visibility and Reporting

Symptoms:
TMM crashes with a core

Conditions:
AFM and AVR provisioned and collecting ACL statistics.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Disable the server-side statistics collection for the Network Firewall Rules using the following menu path:
Security :: Reporting : Settings : Reporting Settings : Network Firewall Rules.

Fix:
Fixed a tmm crash related to ACL statistics

Fixed Versions:
16.1.0, 16.0.1.1, 15.1.2.1

934697-3 : 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
    }
}

Fixed Versions:
