788301-2 : SNMPv3 Hardening

Solution Article: K58243048

Component: TMOS

Symptoms:
SNMPv3 agents do not follow current best practices.

Conditions:
SNMPv3 agents enabled.

Impact:
SNMPv3 agents do not follow current best practices.

Fix:
SNMPv3 features now follow current best practices.

777261-1 : When SNMP cannot locate a file it logs messages repeatedly

Component: TMOS

Symptoms:
When the SNMP daemon experiences an error when it attempts to statfs a file then it logs an error message. If the file is not present then this error is repeatedly logged and can fill up the log file.

Conditions:
When an SNMP request causes the daemon to query a file on disk it is possible that a system error occurs. If the file is not present then the error is logged repeatedly.

Impact:
This can fill up the log with errors.

Fix:
The SNMP daemon has been fixed to log this error once.

774301-1 : Verification of SAML Requests/Responses digest fails when SAML content uses exclusive XML canonicalization and it contains InclusiveNamespaces with #default in PrefixList

Component: Access Policy Manager

Symptoms:
When the BIG-IP system is configured as SAML IdP or SAML SP processes SAML Requests/Responses, the verification of digital signature fails in certain cases:

err apmd[19684]: 01490000:3: modules/Authentication/Saml/SamlSPAgent.cpp func: "verifyAssertionSignature()" line: 5321 Msg: ERROR: verifying the digest of SAML Response

Conditions:
-- BIG-IP system is configured as SAML IdP or SAML SP.

-- SAML sends the "ArtifactResponse" message with both "ArtifactResponse" and "Assertion" signed.

-- This is also applicable to any SAML requests/responses that are signed:
   a) SAML Authentication Request
   b) SAML Assertion
   c) SAML Artifact Response
   e) SAML SLO Request/Response

Impact:
Output does not match the 'Canonicalized element without Signature' calculated by APM. BIG-IP SAML IdP or SAM SP fails to process SAML Requests/Responses resulting in errors. Cannot deploy APM as SAML SP with Assertion Artifact binding.

Workaround:
None.

Fix:
Output now matches the Canonicalized element without Signature' calculated by APM, so deployment occurs without error.

773553-5 : ASM JSON parser false positive.

Component: Application Security Manager

Symptoms:
False positive JSON malformed violation.

Conditions:
-- JSON profile enabled (enabled is the default).
-- Specific JSON traffic is passed.

Impact:
HTTP request is blocked or an alarm is raised.

Workaround:
There is no workaround other than disabling the JSON profile.

Fix:
JSON parser has been fixed as per RFC8259.

771873-2 : TMSH Hardening

Solution Article: K40378764

769809-1 : vCMP guests 'INOPERATIVE' after upgrade

Component: TMOS

Symptoms:
After upgrading the host or creating new vCMP guests, the prompt in the vCMP guests report as INOPERATIVE.

Conditions:
-- The system truncates the unit key. (Note: This occurs because the unit key is designed to be a certain length, and the internally generated unit key for the guest has a NULL in it.)
-- Upgrading the host.
-- Creating new guests.

Impact:
vCMP guests are sent a truncated unit key and fail to decrypt the master key needed to load the config. vCMP Guests report 'INOPERATIVE' after upgrade.

Workaround:
None.

Fix:
The system now handles a guest unit key that has a NULL in it, so vCMP guests are no longer 'INOPERATIVE' after upgrade

766577-5 : APMD fails to send response to client and it already closed connection.

Component: Access Policy Manager

Symptoms:
APMD fails to send response to client and produces error message:
err apmd[8353]: 01490085:3: /pt-qp-campus/apm-cdp-qp-qa:pt-qp-campus:bb651ae6: Response could not be sent to remote client. Socket error: Connection reset by peer

APMD does most of its action with backend authentication servers (e.g., AD, LDAP, RADIUS). If the backend server response is very slow (because of various reasons such as network issues), it might cause slow apmd client response. Sometimes, the client has already closed the connection to the virtual server, so the client connection is no longer valid.

Conditions:
Backend server is slow, causing longer-than-usual response times.

Impact:
This causes the client to close the connection. APMD fails to respond to the client.

The cumulative slowness of the backend server causes delay in response. Most of the time, the client connection is already closed. As a result, the request queue gets full. When apmd starts processing the request from the queue, the client connection is already closed for some of them, and processing those requests still continues, which is unnecessary and causes more delay.

Fix:
The system now tests the client connection after picking up the request from the request queue and before processing.
-- If the connection is already closed, the system drops the request.
-- If the request is already in progress, the system checks the client connection before saving the session variables and sending the response to client.

762453-4 : Hardware cryptography acceleration may fail

Component: TMOS

Symptoms:
Host reports the following error message:
Device error: crypto codec qat-cryptoXX-Y queue is stuck.

Conditions:
Platform with access to Intel QAT cryptography hardware
Hardware cryptography acceleration enabled

Impact:
Hardware cryptography acceleration failure, leading to a failover event.

Workaround:
Disable hardware crypto acceleration for impacted device.

Fix:
Platforms with QAT accelerators now function as expected.

761231-5 : Bot Defense Search Engines getting blocked after configuring DNS correctly

Component: Application Security Manager

Symptoms:
Bot Defense performs a reverse DNS for requests with User-Agents of known Search Engines.

A cache is stored for legal / illegal requests to prevent querying the DNS again.

This cache never expires, so in case of an initial misconfiguration, after fixing the DNS configuration, or routing or networking issue, the Search Engines may still be blocked until TMM is restarted.

Conditions:
-- Initial misconfiguration of DNS or routing or networking issue.
-- Cache stores requests to prevent future queries to DNS.
-- Correct the misconfiguration.

Impact:
Cache does not expire and is never updated, so it retains the misconfigured requests. As a result, valid Search Engines are getting blocked by Bot Defense.

Workaround:
Restart TMM by running the following command:
bigstart restart tmm

Fix:
The internal DNS cache within Bot Defense and DoSL7 now expires after five minutes.

760878-1 : Incorrect enforcement of explicit global parameters

Component: Application Security Manager

Symptoms:
A false positive or false negative enforcement of explicit global parameter.

Conditions:
-- A configuration with more than 255 security policies.
-- Policies configured with an explicit parameter that is unique (for example, 'static', a disabled signature, etc.).
-- Attempt to enforce that parameter.

Impact:
Wrong blocking/violations. The parameter is not found, and the wildcard * parameter is enforced instead.

Workaround:
Make the explicit parameters a wildcard parameter.

Fix:
Explicit parameters are enforced correctly on all parameters.

760550-2 : Retransmitted TCP packet has FIN bit set

Component: Local Traffic Manager

Symptoms:
After TCP sends a packet with FIN, retransmitted data earlier in the sequence space might also have the FIN bit set.

Conditions:
-- Nagle is enabled.
-- TCP has already sent a FIN.
-- A packet is retransmitted with less than MSS bytes in the send queue.

Impact:
The retransmitted packet has the FIN bit set even if it does not contain the end of the data stream. This might cause the connection to stall near the end.

Workaround:
Set Nagle to disabled in the TCP profile.

Fix:
The incorrect FIN bit is removed.

759968-1 : Distinct vCMP guests are able to cluster with each other.

Component: Local Traffic Manager

Symptoms:
--Distinct vCMP guests are able to cluster with each other.

--Guests end up having duplicate rebroad_mac on one or more slots. This can be checked using below command:

clsh tmctl -d blade tmm/vcmp -w 200

Look at the "rebroad_mac" field.

Conditions:
--It is not yet clear under what circumstances the issue occurs.

--One of the ways this issue occurs is when guests are moved between blades and they end up having a non-null and duplicate "rebroad_mac" on one or more slots.

Impact:
Only the vCMP guest acting as primary will be operative.

Workaround:
--Disable clusterd from sending packets over tmm_bp by turning off the db variable clusterd.communicateovertmmbp:

modify sys db clusterd.communicateovertmmbp value false.

Note: This command should be issued on the guest acting as primary since config changes are only allowed on cluster primary.

759480-1 : HTTP::respond or HTTP::redirect in LB_FAILED may result in TMM crash

Component: Local Traffic Manager

Symptoms:
When a request is sent to the virtual server which meets the conditions specified, TMM may crash.

Conditions:
When all of the following conditions are met:

-- Virtual server configured with iRule that contains HTTP::respond or HTTP::redirect in an LB_FAILED event.

-- A command in an LB_FAILED event (does not have to be in the same iRule as the previous point, but must be attached to the same virtual server), that parks the iRule (e.g., table, session, persist, after, HSL).

-- A CLIENT_CLOSED event is present.

-- The pool member fails in some manner, triggering LB_FAILED

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Add reject command to LB_FAILED event to force the serverside of the connection closed before response is sent to the client.

758872-1 : TMM memory leak

Component: Local Traffic Manager

Symptoms:
When a Clustered Multiprocessing (CMP) disabled virtual server enters syncookie mode the flows created on TMM instances other than tmm0 are not removed, resulting in a TMM memory leak.

Note: CMP-disabled virtual servers are not distributed among the available TMM processes, but instead are processed on tmm0.

Conditions:
-- Virtual server is CMP disabled.
-- The same virtual server enters syncookie mode.

Impact:
Elevated memory utilization that may impact performance. In extreme cases, it might lead to out-of-memory crash.

Workaround:
Make sure the virtual server is not CMP disabled, for example, avoid using global variables in iRules.

Fix:
Flows of CMP-disabled virtual servers are now properly removed from all TMM instances.

758764-5 : APMD Core when CRLDP Auth fails to download revoked certificate

Component: Access Policy Manager

Symptoms:
Download CRLDP Auth fails to download revoked certificates, so the list of revoked certificate remains empty (NULL). APMD cores while accessing this empty (NULL) list.

Conditions:
Empty revoked-certificate list handling.

Impact:
APMD core. No access policy enforcement for user session or any MPI-reliant processes, such as rewrite and websso while apmd restarts.

Workaround:
None.

Fix:
The system now checks for empty revoked certificate lists (for NULL) and lets the validation OK (because there is nothing to validate against).

758631-1 : ec_point_formats extension might be included in the server hello even if not specified in the client hello

Component: Local Traffic Manager

Symptoms:
RFC 5246 states that if an extension does not exist in the client hello, it must not exist in the server hello. When an EC cipher suite is selected, the server might send the ec_point_formats extension, even if none exists in the client hello.

Conditions:
-- An EC cipher suite is selected.
-- The client does not send an ec_point_formats extension.

Impact:
Some clients abort the connection in this case.

Workaround:
There is no workaround other than not configuring any EC cipher suites.

Fix:
With this change, the server does not send an unsolicited ec_point_formats extension.

758527-5 : BIG-IP system forwards BPDUs with 802.1Q header when in STP pass-through mode

Component: TMOS

Symptoms:
Under certain conditions BIG-IP may forward VLAN-tagged frames even if the VLAN is not defined on the ingress interface.

Conditions:
Tagged VLANs in use.
STP pass-through mode enabled.

Impact:
Frames not delivered as expected.

Workaround:

758336-2 : Incorrect recommendation in Online Help of Proactive Bot Defense

Component: Application Security Manager

Symptoms:
The online help of Proactive Bot Defense within the DoS profile shows the following under the 'Cross-Domain Requests' section:

Allow configured domains; validate in bulk: ... We recommend this option if your web site has many cross-domain resources.

Allow configured domains; validate upon request: ... We recommend this option if your web site does not have many cross-domain resources.

The recommendation is actually the reverse: for many cross-domain resources, it is better to use 'validate upon request'.

Conditions:
Application has multiple cross-domain resources.

Impact:
Confusing documentation. The recommendation is actually the reverse: for many cross-domain resources, it is better to use 'validate upon request'.

Workaround:
For many cross-domain resources, it is better to use 'validate upon request'.

Fix:
The online help of Proactive Bot Defense has been corrected under the 'Cross-Domain Requests' section.

Workaround:
No workaround aside from removing that iRule.

Fix:
tmm no longer crashes under these conditions.

757088 : TMM clock advances and cluster failover happens during webroot db nightly updates

Component: Traffic Classification Engine

Symptoms:
Webroot database mapping and unmapping takes a very long amount of time on TMM, so you might see clock advances occur. The long interval might result in a failover/state-transition in clustered environment.

Conditions:
-- Webroot database is downloaded.
-- TMM needs to swap to the new instance.

Impact:
TMM does not process traffic because of the long delay in mapping and unmapping, and failover might happen in a clustered environment.

Workaround:
You can avoid this issue by disabling BrightCloud updates, however, your environments will miss the latest updates as a result.

#vi /etc/wr_urldbd/bcsdk.cfg
  DoBcap=true
  DoRtu=false
  DownloadDatabase=false

Fix:
Mapping/Unmapping the database is done asynchronously and the delay is reduced so that the CDP failover doesn't happen.

Conditions:
TCP connections that are aborted before receiving a RESPONSE from a cache.

Impact:
Loss of service until TMM is restarted. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
Aborted DNS queries to a cache no longer cause a TMM crash.

756538-2 : Failure to open data channel for active FTP connections mirrored across an HA pair.

Component: Local Traffic Manager

Symptoms:
Occasionally, attempting to actively open a data channel from an FTP session that is mirrored across a BIG-IP high availability pair will fail. This is due to aggressive port reuse on the active BIG-IP system, causing ports that are still in a TIME_WAIT state to be used for the data connection.

Conditions:
-- Have a BIG-IP HA pair configured.
-- Create an FTP virtual server with mirroring enabled.
-- Have the pool member(s) of the virtual server be either 3CDaemon or IIS servers (this issue has been confirmed only for 3CDaemon and IIS, but it could affect other servers as well).
-- Client attempts to download data through the virtual server via active FTP.

Impact:
Data connections fail to open; data transfer is unsuccessful.

Workaround:
Use passive FTP, or do not use mirroring for FTP virtual servers.

Fix:
Mirrored, active FTP connections no longer fail to open data channels, and now successfully transmit data.

756450-3 : Traffic using route entry that's more specific than existing blackhole route can cause core

Component: Local Traffic Manager

Symptoms:
TMM asserts with 'Attempting to free loopback interface'message.

Conditions:
- Using blackhole routes.
- Have a route entry that is more specific than the existing blackhole route.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Use /32 blackhole routes.

Fix:
TMM no longer cores when using blackhole routes that are less specific than non-blackhole routes.

756270-1 : SSL profile: CRL signature verification does not check for multiple certificates with the same name as the issuer in the trusted CA bundle

Component: Local Traffic Manager

Symptoms:
If there are multiple certificates in the trusted CA bundle with the same common name, CRL signature verification checks only one of them while looking for CRL issuer.

Conditions:
Multiple certificates with the same subject name as the CRL issuer in the trusted CA bundle used for authentication in SSL profiles.

Impact:
Handshake failure.

Workaround:
None.

Fix:
This has been fixed to check for the issuer among all certificates that have the same subject name as the CRL issuer.

756153-1 : Add diskmonitor support for MySQL /var/lib/mysql

Component: TMOS

Symptoms:
If the disk partition /var/lib/mysql is filled to 100%, diskmonitor does not notify that the partition is nearly exhausted.

Conditions:
The disk partition /var/lib/mysql is filled to 100%.

Impact:
diskmonitor does not notify that disk partition /var/lib/mysql is nearly exhausted.

Workaround:
None.

756094-1 : DNS express in restart loop, 'Error writing scratch database' in ltm log

Component: Global Traffic Manager (DNS)

Symptoms:
DNS express (zxfrd) daemon gets stuck in a restart loop with the messages:
-- In /var/log/ltm:
Error writing scratch database (no error information available), serving database is unchanged. zxfrd will exit and restart.
-- The system posts the following message on the command line every few seconds:
emerg logger: Re-starting zxfrd

Conditions:
An update to an SOA record (and only an SOA) is received through a incremental zone transfer update (IXFR).

Impact:
Zone updates from the DNS master servers are not processed.

Workaround:
As a partial workaround, the DNS express cache files can be removed, forcing zxfrd to pull the entire zone using an AXFR request. To do so, use the following commands, in sequence:

   bigstart stop zxfrd
   rm /shared/zxfrd/*
   bigstart start zxfrd

Note: DNS express will not be able to service DNS responses until the zone transfers have completed. For this reason, this procedure should be carried out on the standby device, if possible.

Fix:
The system now properly handles IXFRs that contain only starting and ending SOA RRs, and no other RRs.

755507-1 : [App Tunnel] 'URI sanitization' error

Component: Access Policy Manager

Symptoms:
URI sanitization error with app tunnel (application tunnel). The system posts messages similar to the following:
-- APM log: warning tmm[19703]: 01490586:4: /Common/AP-AD:Common:ff776e4a: Invalid Resource Access For RESOURCENAME. RST due to URI sanitization

752930 : Changing route-domain on partitions leads to Secondary blade reboot loop and virtual servers left in unusual state

Component: Local Traffic Manager

Symptoms:
Virtual Servers left in unknown state. Blade keeps restarting.

Conditions:
Change default route domain (RD) of partition with wildcard Virtual Servers.

Impact:
-- Cannot persist the wildcard virtual server RD configuration.
-- Changing virtual server description after moving route-domain fails.
-- Secondary blade in constant reboot loop.

Workaround:
1. Delete wildcard virtual servers before changing default route-domain on partition.

2. Execute the following commands, in sequence, substituting your values for the configuration-specific ones in this example:

# ssh slot2 bigstart stop

# modify auth partition pa-1098-blkbbsi0000csa21ad1142 default-route-domain 109

# save sys config

# clsh rm -f /var/db/mcpdb.bin

# ssh slot2 bigstart start

Note: This recovery method might have to be executed multiple times to restore a working setup.

752835-1 : Mitigate mcpd out of memory error with auto-sync enabled.

Component: TMOS

Symptoms:
If auto-sync is enabled and many configuration changes are sent quickly, it is possible for a peer system to fall behind in syncs. Once it does, it will exponentially get further behind due to extra sync data, leading to the sending mcpd running out of memory and core dumping.

Conditions:
-- Auto-sync enabled in an HA pair.
-- High volume of configuration changes made in rapid succession. Typically, this requires hundreds or thousands of changes per minute for several minutes to encounter this condition.

Impact:
mcpd crashes.

Workaround:
There are no workarounds other than not using auto-sync, or reducing the frequency of system configuration changes.

Fix:
This is not a complete fix. It is still possible for mcpd to run out of memory due to a peer not processing sync messages quickly enough. It does, however, make it more difficult for this scenario to happen, so configuration changes with auto-sync on can be sent somewhat more quickly without crashing mcpd as often.

751586-1 : http2 virtual does not honour translate-address disabled

Component: Local Traffic Manager

Symptoms:
translate-address disabled on a http2 virtual is getting ignored

Conditions:
http2 virtual and translate-address disabled configured

Conditions:
-- HSL or ReqLog configured to send logging data to pool via TCP protocol.
-- TCP 3-way handshake takes longer than 20 seconds (the default handshake timeout) to complete.

Impact:
-- Service interruption while TMM restarts.
-- Failover event.

Workaround:
None.

Fix:
HSL handles unusually long pending TCP handshakes gracefully and does not cause outage.

750488 : Certain BIG-IP DNS configurations improperly respond to DNS queries that contain EDNS OPT Records

Component: Global Traffic Manager (DNS)

Symptoms:
DNS Cache does not always include an EDNS OPT Record in responses to queries that contain an EDNS OPT Record.

Conditions:
Responses to queries with EDNS0 record to DNS Cache do not contain the RFC-required EDNS0 record.

Impact:
Some compliance tools and upstream DNS servers may consider the BIG-IP non-compliant, and report it as such.

This is occurring now because of the changes coming that remove certain workarounds on February 1st, 2019. This is known as DNS Flag Day. All network configurations on the internet will be affected by this change, but only some DNS servers will be negatively impacted. Fixes for this issue handle the conditions that were once handled by those workarounds.

Workaround:
None.

Fix:
Corrected EDNS OPT record handling in DNS Cache.

Note: Any NOSOA and NOAA results from the EDNS Compliance Tester used for DNS Flag Day are false positives and are expected when testing against DNS Cache. The EDNS Compliance Tester assumes an authoritative server, and makes non-recursive queries. For example, you might see a Resolver response similar to the following:

example1.com. @10.10.10.126 (ns.example1.com.): dns=nosoa,noaa edns=nosoa,noaa edns1=ok edns@512=noaa ednsopt=nosoa,noaa edns1opt=ok do=nosoa,noaa ednsflags=nosoa,noaa optlist=nosoa,noaa,subnet signed=nosoa,noaa,yes ednstcp=noaa

These types of responses are expected when running the validation tool against DNS Cache.

750484 : Certain BIG-IP DNS configurations improperly respond to DNS queries that contain EDNS OPT Records

Component: Global Traffic Manager (DNS)

Symptoms:
DNS Cache drops a DNS query that contains an EDNS OPT Record that it does not understand.

Conditions:
If a client (such as a DNS Flag Day compliance tool) or upstream DNS Server sends an invalid ENDS OPT record.

Impact:
DNS Cache drops the request. Clients (such as a DNS Flag Day compliance tool) or upstream DNS server will experience a timeout for that query.

This is occurring now because of the changes coming that remove certain workarounds on February 1st, 2019. This is known as DNS Flag Day. All network configurations on the internet will be affected by this change, but only some DNS servers will be negatively impacted. Fixes for this issue handle the conditions that were once handled by those workarounds.

Workaround:
None.

Fix:
When a query with an invalid EDNS OPT version is received by DNS Cache, the system now sends a response with the BADVERS error code, as stipulated by the RFC.

Note: Any NOSOA and NOAA results from the EDNS Compliance Tester used for DNS Flag Day are false positives and are expected when testing against DNS Cache. The EDNS Compliance Tester assumes an authoritative server, and makes non-recursive queries. For example, you might see a Resolver response similar to the following:

example1.com. @10.10.10.126 (ns.example1.com.): dns=nosoa,noaa edns=nosoa,noaa edns1=ok edns@512=noaa ednsopt=nosoa,noaa edns1opt=ok do=nosoa,noaa ednsflags=nosoa,noaa optlist=nosoa,noaa,subnet signed=nosoa,noaa,yes ednstcp=noaa

750213-1 : DNS FPGA Hardware-accelerated Cache can improperly respond to DNS queries that contain EDNS OPT Records.

Solution Article: K25351434

Component: Global Traffic Manager (DNS)

Symptoms:
FPGA hardware-accelerated DNS Cache can respond improperly to DNS queries that contain EDNS OPT Records. This improper response can take several forms, ranging from not responding with an OPT record, to a query timeout, to a badvers response.

Conditions:
-- Using VIPRION B2250 blades.
-- This may occur if a client sends a query with an EDNS OPT record that has an unknown version or other values that the Hardware-accelerated Cache does not understand. These errors only occur when matching the query to a hardware cached response.

Note: If the response is not in the hardware cache, then the query should be properly handled.

Impact:
Hardware-accelerated DNS Cache drops the request. Clients will experience a timeout for that query.

This is occurring now because of the changes coming to software from certain DNS software vendors that remove specific workarounds on February 1st, 2019. This is known as DNS Flag Day.

Workaround:
None.

749774-2 : EDNS0 client subnet behavior inconsistent when DNS Caching is enabled

Component: Global Traffic Manager (DNS)

Symptoms:
When EDNS0 client subnet information is included in a DNS request, and DNS caching is enabled, the responses differ in their inclusion of EDNS0 client subnet information based on whether the response was supplied by the cache or not.

Conditions:
This occurs when EDNS0 client subnet information is included in a DNS request, and DNS caching is enabled.

Impact:
Inconsistent behavior.

Workaround:
None.

Fix:
In this release, responses are now consistent when caching is enabled.

749675-2 : DNS cache resolver may return a malformed truncated response with multiple OPT records

Component: Global Traffic Manager (DNS)

Symptoms:
A configured DNS resolving cache returns a response with two OPT records when the response is truncated and not in the cache.

Conditions:
This can occur when:
-- A DNS resolving cache is configured.
-- The DNS query being handled is not already cached.
-- The response for the query must be truncated because it is larger than the size the client can handle (either 512 bytes or the buffer size indicated by an OPT record in the query).

Impact:
A DNS message with multiple OPT records is considered malformed and will likely be dropped by the client.

Workaround:
A second query will return the cached record, which will only have one OPT record.

Fix:
DNS cache resolver now returns the correct response under these conditions.

749508-4 : LDNS and DNSSEC: Various OOM conditions need to be handled properly

Component: Global Traffic Manager (DNS)

Symptoms:
Some LDNS and DNSSEC out-of-memory (OOM) conditions are not handled properly.

-- Pool members are incorrectly marked down.

Workaround:
You can use either of the following:

-- Failover or failback traffic to the affected device.

-- Run the following command: tmsh load sys config.

749294-1 : TMM cores when query session index is out of boundary

Component: Local Traffic Manager

Symptoms:
TMM cores when the queried session index is out of boundary. This is not a usual case. It is most likely caused by the memory corrupted issue.

Conditions:
When session index equals the size of session caches.

Impact:
TMM cores. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
The index boundary check now operates correctly in this situation, so tmm no longer cores.

748205-2 : SSD bay identification incorrect for RAID drive replacement★

Component: TMOS

Symptoms:
On iSeries platforms with dual SSDs, the 'bay' of a given SSD indicated in the 'tmsh show sys raid' command may be incorrect. If a drive fails, or for some other reason it is intended to be replaced, and you are using the bay number listed from the tmsh command, the wrong drive could be removed from the system resulting in system failure to operate or boot.

Conditions:
iSeries platform with dual SSDs.

Impact:
Removal of the one working drive could result in system failure and subsequent failure to boot

Workaround:
If you discover that you removed the incorrect drive, you can attempt to recover by re-inserting the drive into the bay that it was in, and powering on the device.

The following steps will help to avoid inadvertently removing the wrong drive:

As a rule for systems with this issue:
-- Power should be off when you remove a drive. This makes it possible to safely check the serial number of the removed drive.
-- Power should be on, and the system should be completely 'up' before you add a new drive.

Here are some steps to follow to prevent this issue from occurring.

1. Identify the failed drive, taking careful note of its serial number (SN). You can use any of the following commands to get the serial number:
     • tmsh show sys raid
     • tmsh show sys raid array
     • array
2. Logically remove the failed drive using the following command: tmsh modify sys raid array MD1 remove HD<>
3. Power down the unit.
4. Remove the fan tray and physically remove the failed drive.
5. Manually inspect the SN on the failed drive to ensure that the correct drive was removed.
6. Replace the fan tray.
7. Power on the unit with the remaining, single drive.
8. Once booted, wait for the system to identify the remaining (good) drive. You can confirm that this has happened when it appears in the 'array' command output.
9. Remove fan tray again (with the system running).
10. Install the new drive.
11. Use the 'array' command to determine that the new drive is recognized (Note: the tmsh commands do not show new drive at this stage.)
12. Logically add the new drive using the command command: tmsh modify sys raid array MD1 add HD<>
13. Monitor the rebuild using any of the commands shown in step 1.

Note: You must follow these steps exactly. If you insert the new drive while the system is off, and you then boot the system with the previously existing working drive and the new blank drive present, the system recognizes the blank drive as the working Array member, and you cannot add it to the array. That means system responds and replicates as if 'HD already exists'.

748187-1 : 'Transaction Not Found' Error on PATCH after Transaction has been Created

Component: TMOS

Symptoms:
In systems under heavy load of transactions with multiple icrd_child processes, the system might post an erroneous 'Transaction Not Found' response after the transaction has definitely been created.

Conditions:
Systems under heavy load of transactions with multiple icrd_child processes.

Impact:
Failure to provide PATCH to a transaction whose ID has been created and logged as created.

Workaround:
If transaction is not very large, configure icrd_child to only run single-threaded.

Fix:
Erroneous 'Transaction Not Found' messages no longer occur under these conditions.

748177-4 : Multiple wildcards not matched to most specific WideIP when two wildcard WideIPs differ on a '?' and a non-wildcard character

None

Fix:
after fix, the configuration file changes are merged.
Kerberos Auth agent adds the lines it requires and does not override existing settings

747592-4 : PHP vulnerability CVE-2018-17082

Component: TMOS

Symptoms:
The Apache2 component in PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 allows XSS via the body of a "Transfer-Encoding: chunked" request, because the bucket brigade is mishandled in the php_handler function in sapi/apache2handler/sapi_apache2.c.

Conditions:
This exploit doesn't need any authentication and can be exploited via POST request. Because of 'Transfer-Encoding: Chunked' header php is echoing the body as response.

Impact:
F5 products not affected by this vulnerability. Actual impact of this vulnerability is possible XSS attack.

Workaround:
No known workaround.

Fix:
The brigade seems to end up in a messed up state if something fails in shutdown, so we clean it up.

747585-1 : TCP Analytics supports ANY protocol number

Component: Local Traffic Manager

Symptoms:
No TCP analytics data is collected for an ANY virtual server.

Conditions:
1. Provision AVR
2. Create a FastL4 server that accepts all protocols.
3. Attach a TCP Analytics profile
4. Try to run UDP traffic through it.

Impact:
No TCP analytics data is collected for TCP flows when a virtual server's protocol number is ANY.

Workaround:
There is no workaround this time.

Fix:
TCP analytics now supports both ANY and TCP protocol numbers and would collect analytics for TCP flows if protocol number is ANY or TCP.

747192-3 : Small memory leak while creating Access Policy items

Component: Access Policy Manager

Symptoms:
Memory slowly leaks for every access policy item added: 32 + 80 bytes for each item.

Conditions:
The leak occurs while creating new policy items in Access.

Impact:
After a long uptime interval, mcpd may crash due to lack of memory.

Workaround:
Restart mcpd periodically if you modify Access policies frequently by adding or deleting policy items.

Fix:
Leak was fixed by clearing the leaked objects.

747131-1 : ARP table may not be updated properly by some TMMs

Component: Local Traffic Manager

Symptoms:
When receiving ARP request coming from the client, some TMMs may not update the ARP table properly, leading to connectivity failures.

Conditions:
- BIG-IP with autolasthop disabled.
- Client blocking ARP responses.
- BIG-IP relies only on ARP requests coming from the client for sending the traffic back.

Impact:
This will have no impact in most of configurations, since BIG-IP will perform it's own resolution for client's MAC addresses.

In a case where client is not responding to ARP probes sent by Big-IP, the problem may lead to connectivity failures for particular clients.

Workaround:
Configure static ARP entries OR enable autolasthop.

746922-3 : When there is more than one route domain in a parent-child relationship, outdated routing entry selected from the parent route domain may not be invalidated on routing table changes in child route domain.

Component: Local Traffic Manager

Symptoms:
In a situation when a routing entity belonging to the child route domain is searching for an egress point for a traffic flow, it's searching for a routing entry in the child domain first, then if nothing is found, it searches for it in the parent route domain and returns the best found routing entry.

If the best routing entry from the parent route domain is selected, then it is held by a routing entity and is used to forward a traffic flow. Later, a new route entry is added to the child route domain's routing table and this route entry might be better than the current, previously selected, routing entry. But the previously selected entry doesn't get invalidated, thus the routing entity that is holding this entry is forwarding traffic to a less-preferable egress point.

#Example:
RD0(parent) -> RD1(child)
routing table: default gw for RD0 is 0.0.0.0/0%0
pool member is 1.1.1.1/32%1
-
Pool member searches for the best egress point and finds nothing in the routing table for route domain 1, and then later finds a routing entry, but from the parent route domain - 0.0.0.0/0%0.

Later a new gw for RD1 was added - 0.0.0.0/0%1, it's preferable for the 1.1.1.1/32%1 pool member. 0.0.0.0/0%0 should be (but is not) invalidated to force the pool member to search for a new routing entry and find a better one if it exists, as in this case, with - 0.0.0.0/0%1.

Conditions:
1. There is more than one route domain in the parent-child relationship.
2. There are routing entries for the parent route-domain good enough to be selected as an egress point for the routing object (for instance, pool member) which is from child route domain.
3. The routing entry from a parent route domain is selected as an egress point for the object from the child route domain.
4. New routing entry for child route domain is added.

Impact:
If a new added route is preferable to an existing one in a different route domain, the new, preferable, route is not going to be used by a routing object that has previously selected a route. Thus, traffic flows through these routing objects to an unexpected/incorrect egress point. This might result in undesirable behavior:
-- The route might be unreachable, and all traffic for a specific pool member is dropped.
-- The virtual server cannot find an available SNAT address.
-- Simply, the wrong egress interface is being used.

Workaround:
Use either of these workaround after a new route in child domain is added.

-- Recreate a route.
Recreate a parent route domain's routes. Restart tmrouted daemon if routes are gathered via routing protocols.

-- Recreate a routing object.
  - If a pool member is affected, recreate the pool member.
  - If a SNAT pool list is affected, recreate it.
  - And so on.

Fix:
Routing objects are now forced to reselect a routing entry after a new route is added to the child route domain's routing table.

746877-4 : Omitted check for success of memory allocation for DNSSEC resource record

Component: Global Traffic Manager (DNS)

Symptoms:
The TMM may panic from SIGABRT while logging this message:
./rdata.c:25: ldns_rdf_size: Assertion `rd != ((void *)0)' failed.

Conditions:
During memory stress while handling DNSSEC traffic.

Impact:
TMM panic and subsequent interruption of network traffic.

Workaround:
Keeping the workload within normal ranges reduces the probability of encounter.

Fix:
The system now checks for success of memory allocation for DNSSEC resource record, so this issue no longer occurs.

746868 : memory leakage when "apply to base domain" is enabled

Component: Fraud Protection Services

Symptoms:
Memory leakage when "apply to base domain" is enabled. this can result in a crash or aggressive sweeper mode.

Impact:
Aggressive connections sweeper mode, and traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

746768-2 : APMD leaks memory if access policy policy contains variable/resource assign policy items

Component: Access Policy Manager

Symptoms:
If an access policy contains variable/resource assign policy items, APMD will leak memory every time the policy is modified and applied.

Conditions:
1. Access policy has variable/resource assign policy items.
2. The access policy is modified and applied.

Impact:
APMD's memory footprint will increase whenever the access policy is applied.

Workaround:
There is no workaround.

Fix:
Memory growth has been addressed.

746266-4 : Vcmp guest vlan mac mismatch across blades.

Component: TMOS

Symptoms:
Guests running on blades in a single chassis report different MAC addresses on a single vlan upon host reboot for vcmp guest.

Conditions:
This issue may be seen when all of the following conditions are met:

- One (or more) blade(s) are turned off completely via AOM.
- Create two vlans.
- Deploy a multi-slot guest with the higher lexicographic vlan.
- Now, assign the smaller vlan to the guest.
- Reboot the host

Impact:
Incorrect MAC addresses are reported by some blades.

Workaround:
There is no workaround at this time.

745713-2 : TMM may crash when processing HTTP/2 traffic

Solution Article: K94563344

745654-1 : Heavy use of APM Kerberos SSO can sometimes lead to slowness of Virtual Server

Component: Access Policy Manager

Symptoms:
When there are a lot of tcp connections that needs new kerberos ticket to be fetched from kdc, then the websso processes requests slower than the incoming requests. This could lead to low throughput and virtual server is very slow to respond to requests.

Conditions:
Large number of APM users using Kerberos SSO to access backend resources and all the tickets expire at the same time.

Impact:
Low throughput and slow responses from Virtual server.

Workaround:
There is no workaround at this time.

Fix:
Increase the size of websso worker queue, so that tmm and websso process can communicate effectively. This eliminates VS slowness and hence increase throughput.

745574-4 : URL is not removed from custom category when deleted

Component: Access Policy Manager

Symptoms:
When the admin goes to delete a certain URL from a custom category, it should be removed from the category and not be matched anymore with that category. In certain cases, the URL is not removed effectively.

Conditions:
This only occurs when the syntax "http*://" is used at the beginning of the URL when inserted into custom categories.

Impact:
When the URL with syntax "http*://" is deleted from the custom category, it will not take effect for SSL matches. For example, if "http*://www.f5.com/" was inserted and then deleted, and the user passed traffic for http://www.f5.com/ and https://www.f5.com/, the SSL traffic would still be categorized with the custom category even though it was deleted. The HTTP traffic would be categorized correctly.

Workaround:
"bigstart restart tmm" will resolve the issue.

Fix:
Made sure that the deletion takes effect properly and SSL traffic is no longer miscategorized after removal of the URL from the custom category.

745405 : Under heavy SSL traffic, sw crypto codec queue is stuck and taken out of service without failover

Component: TMOS

Symptoms:
Under heavy SSL traffic, it is observed that sw crypto codec queue is stuck and taken out of service, but no failover happened

Conditions:
Heavy SSL traffic

Impact:
Traffic is impacted and a large number of SSL handshakes to the BIG-IP are failing.

Workaround:
Increase crypto.queue.timeout to a much larger number(from 100 to 500 for example). Restart tmms for the change to take effect.

745387-4 : Resource-admin user roles can no longer get bash access

Component: TMOS

Symptoms:
Resource-admin users with bash access may write to system files beyond the scope of their assigned access.

Conditions:
Resource-admin users configured with bash shell access.

Impact:
Resource-admin users with bash access may write to system files causing security risks.

Workaround:
Do not assign bash access for resource-admin users.

Fix:
Resource-admin users restricted to tmsh access now. If a resource-admin user had bash access in a prior version and upgrades to this version, that user will get converted to tmsh access automatically after the upgrade process.

Behavior Change:
Resource-admin roles can no longer have bash shell access. And upon upgrade, resource-admin users with bash access will get converted to tmsh shell access.

744959-2 : SNMP OID for sysLsnPoolStatTotal not incremented in stats

Component: Carrier-Grade NAT

Symptoms:
SNMP OID for sysLsnPoolStatTotal is not incremented in stats totals.

Conditions:
This affects all of the global port block allocation (PBA) counters.

Impact:
SNMP OID for sysLsnPoolStatTotal is not incremented when it should be. Stats are not accurate.

Workaround:
None.

Fix:
SNMP OID for sysLsnPoolStatTotal is now incremented in stats totals.

744937-4 : Make authenticated-denial-of-existence NSEC3 RR Types Bitmap reflect available Resource Records

Solution Article: K00724442

Component: Global Traffic Manager (DNS)

Symptoms:
BIG-IP does not know what resource records some external zone holds at the time the BIG-IP is responding to some dnssec query that asked for some record type at some owner name.
If the resource record type does not exist, then as part of the response, the BIG-IP generates an NSEC3 record (to authenticate denial of existence along with RRSIG) containing a types bitmap that is supposed to have the available RRs at the owner name.
With some new feature supported in BIND 9.12 (RFC 8198) called Aggressive use of Negative Cache, that negative response with the inaccurate types bitmap is cached which can then be re-used to show that some resource records do not exist but are in fact available at the owner name.

Conditions:
A query comes in for a zone that is not hosted on the BIG-IP where the BIG-IP is only responsible for DNSSEC signing.

Impact:
Validating resolvers implementing Aggressive Use of DNSSEC-Validated Cache may respond with NODATA for an existing resource record.

Workaround:
N/A

744707-1 : Crash related to DNSSEC key rollover

Component: Global Traffic Manager (DNS)

Symptoms:
When running out of memory, a DNSSKEY rollover event might cause a tmm crash and core dump.

Conditions:
-- System has low memory or is out of memory.
-- DNSSKEY rollover event occurs.

Impact:
tmm crashes and restarts. Traffic disrupted while tmm restarts.

Workaround:
There is no workaround.

Fix:
Fixed an issue in DNSSEC Key Rollover event that could cause a crash.

744536 : HTTP/2 may garble large headers

Component: Local Traffic Manager

Symptoms:
The HTTP/2 filter may incorrectly encode large headers.

Conditions:
A header that encodes to larger than 2048 bytes.

Impact:
Application functionality may be disrupted because large header values, such as for cookies, may be truncated when passed to the endpoint.

Workaround:
None.

Fix:
The HTTP/2 filter now correctly encodes large HTTP headers.

744516-2 : TMM panics after a large number of LSN remote picks

Component: Carrier-Grade NAT

Symptoms:
TMM panics with the assertion 'nexthop ref valid' failed. This occurs after a large number of remote picks cause the nexthop reference count to overflow.

Conditions:
An LSN Pool and remote picks. Remote picks occur when the local TMM does not have any addresses or port blocks available. Remote picks are more likely when inbound and hairpin connections are enabled.

Impact:
TMM restarts. Traffic is interrupted.

Workaround:
There is no workaround.

Fix:
TMM no longer panics regardless of the number of remote picks.

744347-1 : Protocol Security logging profiles cause slow ASM upgrade and apply policy

Component: Application Security Manager

Symptoms:
ASM upgrade and apply policy are delayed by an additional 3 seconds for each virtual server associated with a Protocol Security logging profile (regardless of whether ASM is active on that virtual server). During upgrade, all active policies are applied, which leads to multiple delays for each policy.

Conditions:
There are multiple virtual servers associated with Protocol Security logging profiles.

Impact:
ASM upgrade and apply policy are delayed.

Workaround:
There is no workaround at this time.

744331-1 : OpenSSH hardening

Component: TMOS

Symptoms:
The default OpenSSH configuration does not follow best practices for security hardening.

Conditions:
Administrative SSH access enabled.

Impact:
OpenSSH does not follow best practices.

Fix:
The default OpenSSH configuration includes best practices for security hardening.

744269-3 : dynconfd restarts if FQDN template node deleted while IP address change in progress

Component: Local Traffic Manager

Symptoms:
The dynconfd daemon may crash and restart if an FQDN template node is deleted (by user action or config sync) while ephemeral nodes are in the process of being created, and deleted as the result of new IP addresses being returned by a recent DNS query.

Conditions:
This may occur on BIG-IP version 14.0.0.3 (and BIG-IP versions 13.1.x or v12.1.x with engineering hotfixes for ID 720799, ID 721621 and ID 726319), under the following conditions:
1. A DNS query returns a different set of IP addresses for one or more FQDN names.
2. While new ephemeral node(s) are being created (for new IP addresses and deleted (for old IP addresses), an FQDN template node is deleted (either by user action or config sync).

Impact:
The dynconfd daemon crashes and restarts.
Ephemeral nodes may not be updated in a timely manner while the dynconfd daemon is restarting.

Fix:
The dynconfd daemon does not crash and restart if an FQDN template node is deleted while ephemeral nodes are in the process of being created and deleted as the result of new IP addresses being returned by a recent DNS query.

744117-6 : The HTTP URI is not always parsed correctly

Solution Article: K18263026

Component: Local Traffic Manager

Symptoms:
The HTTP URI exposed by the HTTP::uri iRule command, Traffic Policies, or used by ASM is incorrect.

Conditions:
-- HTTP profile is configured.
-- The URI is inspected.

Impact:
If the URI is used for security checks, then those checks might be bypassed.

Workaround:
None.

Fix:
The HTTP URI is parsed in a more robust manner.

Symptoms:
TMM may core during an IPsec cleanup of a failed async operation.

Conditions:
When an async IPsec crypto operation fails to queue.

Impact:
Restart of tmm. All tunnels lost must be re-established.

Workaround:
No workaround known at this time.

743790-4 : BIG-IP system should trigger a HA failover event when expected HSB device is missing from PCI bus

Component: TMOS

Symptoms:
In some rare circumstances, the HSB device might drop off the PCI bus, resulting in the BIG-IP system not being able to pass traffic. However, no high availability (HA) failover condition is triggered, so the BIG-IP system stays active.

Conditions:
HSB drops off the PCI bus. This is caused in response to certain traffic patterns (FPGA issue) that are yet to be determined.

Impact:
No failover to standby unit after this error condition, causing site outage.

Workaround:
None.

Fix:
Now the active BIG-IP system fails over to the standby when HSB on the active unit drops off the PCI bus.

742237-1 : CPU spikes appear wider than actual in graphs

Component: Local Traffic Manager

Symptoms:
Graphs of CPU usage show spikes that are wider than actual CPU usage.

Conditions:
CPU usage has spikes.

Impact:
Graphs of CPU spikes appear to last longer than they actually last.

Workaround:
Perform the following procedure:

1. Run the following command to record the 5-second average rather than the 1-second average:

sed -i.bak 's/TMCOLNAME "ratio"/TMCOLNAME "five_sec_avg.ratio"/;s/TMCOLNAME "cpu_ratio_curr"/TMCOLNAME "cpu_ratio_5sec"/g' /config/statsd.conf

2. Restart statsd to load the new configuration:

bigstart restart statsd

Fix:
CPU samples for graphs are averaged over longer time to more closely represent actual time between samples.

742226-3 : TMSH platform_check utility does not follow best security practices

Solution Article: K11330536

742078-1 : Incoming SYNs are dropped and the connection does not time out.

Component: Local Traffic Manager

Symptoms:
There is a hard-coded limit on the number of SYNs forwarded on a FastL4 connection. This might cause a problem when a connection is reused, for example, if a connection is not correctly closed.

Conditions:
-- SYN forwarding on FastL4 connections.
-- The number of SYNs on a single connection reaches the hard-coded limit.

Impact:
If the number of SYNs on a single connection reaches this limit, subsequent incoming SYNs are dropped and the connection might not time out.

Workaround:
There is no workaround.

Fix:
The following command enables the forwarding of an an unlimited number of SYNs:
tmsh modify sys db tm.dupsynenforce value disable

741919-1 : HTTP response may be dropped following a 100 continue message.

Component: Local Traffic Manager

Symptoms:
When a 100 response a quickly followed by another HTTP response (2xx/4xx), the second response might be dropped.

Conditions:
When a 100 response is quickly followed by another HTTP response (i.e., a 2xx/4xx response arrives within a few microseconds).

Impact:
The second response might be dropped, so the end user client might not receive all the HTTP responses coming from the server.

Note: This does not happen all the time, and depends on how the underlying data packets are formed and delivered to the HTTP filter.

Workaround:
You can use either of the following workarounds:
-- Use an iRule to disable the HTTP filter in the HTTP_REQUEST event.

-- Disable LRO by running the following command:
tmsh modify sys db tm.tcplargereceiveoffload value disable

741423-1 : Secondary blade goes offline when provisioning ASM/FPS on already established config-sync

Component: TMOS

Symptoms:
When provisioning ASM for the first time on a device that is already linked in a high availability (HA) config-sync configuration, any other cluster device that is on the trust domain experiences mcpd restarting on all secondary blades due to a configuration error.

The system logs messages similar to the following in /var/log/ltm:
-- notice mcpd[12369]: 010718ed:5: DATASYNC: Done initializing datasync configuration for provisioned modules [ none ].
-- err mcpd[9791]: 01020036:3: The requested device group device (/Common/datasync-device-test1.lab.com-dg /Common/test1.lab.com) was not found.
-- err mcpd[9791]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020036:3: The requested device group device (/Common/datasync-device-test1.lab.com-dg /Common/test1.lab.com) was not found.... failed validation with error 16908342.
-- notice mcpd[12369]: 0107092a:5: Secondary slot 2 disconnected.

Conditions:
-- Cluster devices are joined in the trust for HA or config-sync.
-- Provisioning ASM or FPS on clusters which are already joined in a trust.
-- ASM and FPS have not been provisioned on any of the devices: this is the first ASM/FPS provisioning in the trust.

Impact:
Traffic on all secondary blades is interrupted while mcpd restarts. Then, traffic is resumed.

Workaround:
Before provisioning ASM/FPS (but after setting up a trust configuration):

1. On the device on which ASM/FPS is about to be provisioned, create the datasync-global-dg device group and add all of the available devices.

For example, if there are two devices in the Trust Domain: test1.lab.com and test2.lab.com, and you plan to provision ASM/FPS for the first time on test1.lab.com, first run the following command from test1.lab.com:

tmsh create cm device-group datasync-global-dg devices add { test1.lab.com test2.lab.com }

2. Do not sync the device group.
3. Then on test1.lab.com, you can provision ASM/FPS.

Fix:
Secondary blades no longer go offline when provisioning ASM/FPS on already established HA or config-sync configurations.

741108 : tmm dosl7 memory leak when X-Forwared-For header value contains a long list of comma separated ip addresses

Conditions:
-- ASM provisioned.
-- ASM policy attached on a virtual server.
-- ASM policy has device ID enabled.
-- HTTP profile accept_xff enabled.

Impact:
Unexpected tmm out-of-memory state can be reached, causing sweeper activity and disrupting traffic.

Workaround:
Disable accept_xff in HTTP profile that is assigned to a virtual server along with ASM policy.

Fix:
The leak is now fixed.

740963-3 : VIP-targeting-VIP traffic can cause TCP retransmit bursts resulting in tmm restart

Component: Local Traffic Manager

Symptoms:
VIP-on-VIP traffic might cause TCP retransmit bursts, which in certain situations can cause tmm to restart.

Conditions:
- Virtual server handling TCP traffic.
- iRule using the 'virtual' command.

Impact:
Temporary memory consumption and potential for tmm to restart. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
TCP retransmit bursts are now handled gracefully.

740959-1 : User with manager rights cannot delete FQDN node on non-Common partition

Component: Local Traffic Manager

Symptoms:
A user that has manager rights for a non-Common partition, but not for the /Common partition, may be denied delete privileges for an FQDN template node that is created on the non-Common partition for which the user does have manager rights.

This occurs because ephemeral nodes created from the FQDN template node are 'shared' in the /Common partition, so the delete transaction fails because the user has insufficient permissions to delete the dependent ephemeral nodes on the /Common partition.

Conditions:
-- A user is created with manager rights for a non-Common partition.

-- That user does not have manager rights for the /Common partition;

-- At least one ephemeral node is created from that FQDN template node (due to DNS lookup), which is not also shared by other FQDN template nodes.

-- That user attempts to delete an FQDN template node on the non-Common partition for which the user has manager rights.

Impact:
The transaction to delete the FQDN template node fails due to insufficient permissions. No configuration changes occur as a result of the FQDN template node-delete attempt.

Workaround:
You can use either of the following workarounds:

-- Perform the FQDN template node-delete operation with a user that has manager rights to the /Common partition.

-- Create the FQDN template node on the /Common partition.

Fix:
A user with manager rights for a non-Common partition that has no manager rights to the /Common partition, is now able to successfully delete an FQDN template node created on that non-Common partition.

740777-2 : Secondary blades mcp daemon restart when subroutine properties are configured

Component: Access Policy Manager

Symptoms:
Secondary blades' MCP daemons restart with the following error messages:
-- err mcpd[26818]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020036:3: The requested Subroutine Properties (/Common/confirm_10 /Common/confirm_10) was not found.... failed validation with error 16908342.

Conditions:
When a subroutine is configured in the access policy.

Impact:
The secondary blade MCP daemon restarts. Cannot use subroutine in the access policy.

Workaround:
There is no workaround other than to not use subroutine in the access policy.

Fix:
You can now use subroutines in the access policy.

740490-2 : Configuration changes involving HTTP2 or SPDY may leak memory

Component: Local Traffic Manager

Symptoms:
If virtual servers which have HTTP2 or SPDY profiles are updated, then the TMM may leak memory.

Conditions:
-- A virtual server has a HTTP2 or SPDY profile.
-- Any configuration object attached to that virtual server changes.

Impact:
The TMM leaks memory, and may take longer to execute future configuration changes. If the configuration changes take too long, the TMM may be restarted by SOD.

Workaround:
None.

Fix:
The TMM no longer leaks memory when virtual servers that contain a HTTP2 or SPDY profile are reconfigured.

739971-3 : Linux kernel vulnerability: CVE-2018-5391

Component: TMOS

Symptoms:
IP fragments with random offsets allow a remote denial of service (FragmentSmack)

Conditions:
A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.

Impact:
remote denial of service (FragmentSmack)

739970-3 : Linux kernel vulnerability: CVE-2018-5390

Solution Article: K95343321

739963-1 : TLS v1.0 fallback can be triggered intermittently and fail with restrictive server setup

Component: Local Traffic Manager

Symptoms:
HTTPS monitors mark a TLS v1.2-configured pool member down and never mark it back up again, even if the pool member is up. The monitor works normally until the SSL handshake fails for any reason. After the handshake fails, the monitor falls back to TLS v1.1, which the pool members reject, and the node remains marked down.

Conditions:
This might occur when the following conditions are met:
-- Using HTTPS monitors.
-- Pool members are configured to use TLS v1.2 only.

Impact:
Once the handshake fails, the monitor remains in fallback mode and sends TLS v1.0 or TLS v1.1 requests to the pool member. The pool member remains marked down.

Workaround:
To restore the state of the member, remove it and add it back to the pool.

739947-3 : TMM may crash while processing APM traffic

Solution Article: K42465020

739945-1 : JavaScript challenge on POST with 307 breaks application

Component: Application Security Manager

Symptoms:
A JavaScript whitepage challenge does not reconstruct when the challenge is on a POST request and the response from the back-end server is 307 Redirect. This happens only if the challenged URL is on a different path than the redirected URL. This prevents the application flow from completing.

Conditions:
- JavaScript challenge / CAPTCHA is enabled from either Bot Defense, Proactive Bot Defense, Web Scraping, DoSL7 Mitigation or Brute Force Mitigation.
- The challenge is happening on a POST request on which the response from the server is a 307 Redirect to a different path.

Impact:
Server is not able to parse the request payload and application does not work. This issue occurs because the TS*75 cookie is set on the path of the challenged URL, so the redirected URL does not contain the cookie, and the payload is not reconstructed properly to the server.

Workaround:
As a workaround, you can construct an iRule to identify that the response from the server is 307 Redirect, retrieve the TS*75 cookie from the request, and add to the response a Set-Cookie header, setting the TS*75 cookie on the '/' path.

Fix:
Having a JavaScript challenge on a POST request with 307 Response no longer prevents the application from working.

739927-1 : Bigd crashes after a specific combination of logging operations

Component: Local Traffic Manager

Symptoms:
Bigd crashes. Bigd core will be generated.

Conditions:
1. Boot the system and set up any monitor.
2. Enable and disable bigd.debug:
-- tmsh modify sys db bigd.debug value enable
-- tmsh modify sys db bigd.debug value disable
3. Enable monitor logging.

Impact:
Bigd crashes.

Workaround:
None.

Fix:
Bigd no longer crashes under these conditions.

739846-4 : Potential Big3D segmentation fault when not enough memory to establish a new iQuery Connection

Component: Global Traffic Manager (DNS)

Symptoms:
When the big3d runs out of memory for iQuery connections, a segmentation fault might occur.

Conditions:
-- Not enough memory to create additional iQuery connections.
-- Receive an new iQuery connection.

Impact:
Segmentation fault and big3d restarts. No statistics collection or auto-discovery while big3d restarts.

Workaround:
None.

Fix:
The big3d process no longer gets a segmentation fault when reaching the limits of the memory footprint while trying to establish iQuery connections.

739798 : Massive number of log messages being generated and written to the bd.log.

Component: Application Security Manager

Symptoms:
Log messages regarding parameters might fill the bd.log file. The system logs messages appear similar to the following:

deleting job-> converterd key
deleting p_node

Conditions:
No special conditions are required to cause this to occur.

Impact:
Lots of I/O processing. Potentially large bd.log file.

Workaround:
None.

Fix:
Fixed a scenario that resulted in a massive number of log messages being generated and written to the bd.log.

739744-2 : Import of Policy using Pool with members is failing

Component: Access Policy Manager

Symptoms:
Import of Policy using Pool with members is failing with an error Pool member node (/Common/u.x.y.z%0) and existing node (/Common/u.x.y.z) cannot use the same IP Address (u.x.y.z)

Conditions:
Policy has pool attached to it with resource assign or chained objects

Impact:
Policy is not being imported on the same box

Workaround:
There is no workaround at this time.

Fix:
ng-import is now importing policy correctly.

739638-1 : BGP failed to connect with neighbor when pool route is used

Component: Local Traffic Manager

Symptoms:
BGP peering fails to be established.

Conditions:
- Dynamic routing enabled.
- BGP peer connect through a pool route or ECMP route.

Impact:
BGP dynamic route paths are not created.

Workaround:
Use a gateway route.

Fix:
BGP peering can be properly established through a pool route.

739144-1 : Domain logoff scripts runs after VPN connection is closed

Component: Access Policy Manager

Symptoms:
APM Network Access option: 'Execute logoff scripts on connection termination' does not work when script runs after VPN connection is closed.

Conditions:
Following options configured for Microsoft Windows clients:
* Synchronize with Active Directory policies on connection establishment.
and
* Execute logoff scripts on connection termination.

-- Windows client is part of a domain.
-- Domain logoff script is not available without VPN connection.

Impact:
'Execute logoff scripts on connection termination' does not work when script runs after VPN connection is closed.

Workaround:
None.

Fix:
Changes in APM client allow it to wait until domain logoff script execution completes before closing VPN connection, so this issue no longer occurs.

739094-4 : APM Client Vulnerability: CVE-2018-5546

Solution Article: K54431371

738945-1 : SSL persistence does not work when there are multiple handshakes present in a single record

Component: Local Traffic Manager

Symptoms:
SSL persistence hangs while parsing SSL records comprising multiple handshake messages.

Conditions:
This issue intermittently happens when an incoming SSL record contains multiple handshake messages.

Impact:
SSL persistence parser fails to parse such messages correctly. The start of the record may be forwarded on to server but then connection will stall and eventually idle timeout.

Workaround:
There is no workaround other than using a different persistence, or disabling SSL persistence altogether.

After changing or disabling persistence, the transaction succeeds and no longer hangs.

738887-2 : The snmpd daemon may leak memory when processing requests.

Component: TMOS

Symptoms:
Under certain conditions, the snmpd daemon may leak memory when processing requests.

Conditions:
This issue is known to occur on a multi-blade vCMP guest after specific maintenance operations have been carried out by an Administrator on the guest.

Impact:
Once enough memory has leaked, the system may become unstable and fail unpredictably.

Workaround:
If the snmpd daemon is consuming excessive memory, restart it with the following command:

bigstart restart snmpd

Fix:
The snmpd daemon no longer leaks memory when a multi-blade vCMP guest reaches a certain condition.

738789-3 : ASM/XML family parser does not support us-ascii encoding when it appears in the document prolog

Component: Application Security Manager

Symptoms:
ASM blocks requests when a request payload is an xml document with a prolog line at the begging with encoding="us-ascii".

Conditions:
- ASM provisioned.
- ASM policy attached to a virtual server.
- ASM handles XML traffic with encoding="us-ascii" (use of the value encoding="us-ascii" is very uncommon, the typical value is encoding="utf-8").

Impact:
Blocked XML requests.

Workaround:
You can use either of the following workarounds:

-- Remove XML profile from a URL in the ASM policy.

-- Disable XML malformed document detection via ASM policy blocking settings.

Fix:
XML parser now supports encoding="us-ascii".

738669-3 : Login validation may fail for a large request with early server response

Component: Fraud Protection Services

Symptoms:
in case of large request/response, if FPS needs to store ingress and ingress chunks in buffer for additional processing (ingress :: for parameter parsing, egress :: for login validation's banned/mandatory strings check or scripts injection), if the server responds fast enough, the buffer may contain mixed parts of request/response. This may have several effects, from incorrectly performing login-validation to generating a tmm core file.

Conditions:
-- Login validation is enabled and configured to check for banned/mandatory string.
-- A username parameter is configured.
-- There are no parameters configured for encrypt/HTML Field Obfuscation (HFO), and no decoy parameters.
-- There is a large request and response.
-- The system response very quickly.

Impact:
This results in one or more of the following:
-- Login validation failure/skip.
-- Bad response/script injection.
-- tmm core. In this case, traffic is disrupted while tmm restarts.

Workaround:
None.

Fix:
FPS now handles ingress/egress buffers separately, so this issue no longer occurs.

738647-1 : Add the login detection criteria of 'status code is not X'

Component: Application Security Manager

Symptoms:
There is a criterion needed to detect successful login.

Conditions:
Attempting to detect successful login when the response code is not X (where 'x' = some code).

Impact:
Cannot configure login criteria.

Workaround:
None.

Fix:
This release adds a new criterion to the login criteria.

738523-3 : SMTP monitor fails to handle multi-line '250' responses to 'HELO' messages

Component: Local Traffic Manager

Symptoms:
When monitoring an SMTP server that emits multi-line '250' responses to the initial 'HELO' message, the monitor fails. If monitor logging is enabled on the pool member, the system posts an error similar to the following in the monitor log:

09:50:08.580145:(_Tcl /Common/mysmtp): ERROR: failed to complete the transfer, Failed to identify domain.

Conditions:
-- Monitoring an SMTP server.
-- SMTP server is configured to return a multi-line '250' response to the initial 'HELO' message.

Impact:
The pool member is marked down even though it is actually up.

Workaround:
None.

Fix:
The system now handles multi-line '250' responses to the initial 'HELO' message.

738521-2 : i4x00/i2x00 platforms transmit LACP PDUs with a VLAN Tag.

Component: Local Traffic Manager

Symptoms:
A trunk configured between a BIG-IP i4x00/i2x00 platform and an upstream switch may go down due to the presence of the VLAN tag.

Conditions:
LACP configured between a BIG-IP i4x00/i2x00 platform and an upstream switch.

Impact:
Trunks are brought down by upstream switch.

Workaround:
There are two workarounds:

-- Configure the trunk as 'untagged' in one of the VLANs in which it's configured.
-- Disable LACP.

Fix:
The system no longer transmits a VLAN tag for LACP PDUs, so this issue no longer occurs.

738445-1 : IKEv1 handles INVALID-SPI incorrectly in parsing SPI and in phase 2 lookup

Component: TMOS

Symptoms:
INVALID_SPI notification does not delete the IPsec-SA with the SPI value that appears in the notify payload. This occurs because the handler of INVALID-SPI notifications performs the following incorrect actions:

-- Fetches SPI from payload as if it's a string, rather than the network byte order integer it actually is.

-- Attempts phase 2 lookup via selector ID (reqid) rather than SPI.

Either alone prevents finding the SA to delete.

Conditions:
An IKEv1 IPsec peer sends an INVALID-SPI notification to the BIG-IP system.

Impact:
The IPsec-SA with that SPI cannot be found and is not deleted.

Workaround:
From the BIG-IP command line, you can still manually delete any IPsec-SA, including the invalid SPI, using the following command:
# tmsh delete net ipsec ipsec-sa spi <spi number>

Fix:
SPI is now extracted correctly from the payload as a binary integer, and the phase 2 SA lookup is done with a proper SPI search, which also requires a match in the peer address.

738397-2 : SAML -IdP-initiated case that has a per-request policy with a logon page in a subroutine fails.

Component: Access Policy Manager

Symptoms:
For a BIG-IP system configured as IdP, in the SAML-IdP-initiated case: If the IdP has a Per-Request policy (in addition to a V1 policy), such that the Per-Request policy has a subroutine or a subroutine macro with a logon page, the system reports access failure on running the policy.

The error logged is similar to the following: '/Common/sso_access:Common:218f759e: Authorization failure: Denied request for SAML resource /Common/saml_resource_obj1&state=000fffff032db022'.

Conditions:
-- BIG-IP system configured as IdP.
-- SAML IdP initiated case in which the following is true:
+ The IdP has a Per-Request policy (in addition to a V1 policy).
+ That Per-Request policy has a subroutine or a subroutine macro with a logon page.

Impact:
Access is denied. The request URI has '&state=<per-flow-id>' appended to the SAML Resource name.

Workaround:
None.

Fix:
The system now checks for additional query parameters in the request_uri while extracting Resource name so it is not incorrectly set to 'ResourceName&state=<per-flow-id>' which causes the access failure.

738119-3 : SIP routing UI does not follow best practices

Solution Article: K23566124

738046-3 : SERVER_CONNECTED fires at wrong time for FastL4 mirrored connections on standby

Component: Local Traffic Manager

Symptoms:
For FastL4 connections, SERVER_CONNECTED currently doesn't fire on the standby device. If the standby device then becomes active, the first packet from the server on an existing FastL4 connection causes SERVER_CONNECTED to fire. Depending on what the iRule does in SERVER_CONNECTED, a variety of results can occur, including TMM coring due to commands being executed in unexpected states.

Conditions:
-- High availability configuration.
-- Mirrored FastL4 virtual server.
-- Attached iRule contains a SERVER_CONNECTED event.

Impact:
SERVER_CONNECTED does not fire when expected on standby device. When the standby device becomes active, the SERVER_CONNECTED iRule may cause TMM to core with traffic being disrupted while TMM restarts.

Workaround:
None.

Fix:
SERVER_CONNECTED now fires when expected on the standby device.

737998 : Brute Force end attack condition isn't satisfied for successful logins only

Component: Application Security Manager

Symptoms:
When brute force attack is detected and prevented by asm, asm continue to prevent login attempts even the attacking traffic has stopped 5 minutes ago.

Conditions:
- ASM provisioned
- ASM policy attached to a virtual server
- ASM Brute Force protection enabled in the asm policy
- There is an ongoing brute force attack on the backend server.

Impact:
ASM doesn't report that brute force attack is finished and logins mitigation continues to occur.

Workaround:
While ongoing endless brute force attack, change an arbitrary field in brute force configuration and apply policy. Brute force attack end event will be triggered and the system will stop brute force prevention, if the attacking traffic still being sent, new brute force attack event will be raised and the mitigation will reoccur.

Fix:
Fix brute force end condition check for a case when only successful logins are sent.

737910-1 : Security hardening on the following platforms

Solution Article: K18535734

737758-1 : MPTCP Passthrough and VIP-on-VIP can lead to TMM core

Component: Local Traffic Manager

Symptoms:
If a FastL4 virtual server has an iRule that uses the 'virtual' command to direct traffic to a virtual server with MPTCP passthrough enabled, TMM may produce a core upon receiving certain traffic.

Conditions:
A FastL4 virtual server has an iRule that uses the 'virtual' command to direct traffic to a virtual server with a TCP profile attached that has MPTCP passthrough enabled, and certain traffic is received.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
There is no workaround other than not using an iRule with the 'virtual' command to direct traffic to a virtual server with MPTCP passthrough enabled.

Fix:
If MPTCP passthrough is enabled, the system now processes incoming MPTCP connections coming from the loop device as if MPTCP is disabled.

737597 : AVR DoS Attack report misses virtual server name in a specific config

Component: Application Visibility and Reporting

Symptoms:
DoS AVR Report GUI page is under:
Navigate to Security :: Reporting : DoS : Network

The report shows the attack, but categorizes the attack under 'Aggregated' in the Virtual Server name value, rather than the actual name of the Virtual Server on which the attack is happening.

Conditions:
-- A Virtual Server is configured with a IP/Subnet range.

For example,
-- Virtual Server with Destination Address: 10.10.10.0/27 (meaning the destination range is 10.10.10.32 - 10.10.10.63).
-- Destination Address of the Client Traffic and Attack: 10.10.10.63

View AVR Reporting, which does not resolve the to any specific Virtual Server, but instead categorizes the attack as 'Aggregate'.

Impact:
AVR report missing the Virtual Server information.

Workaround:
None.

737437-1 : IKEv1: The 4-byte 'Non-ESP Marker' may be missing in some IKE messages

Component: TMOS

Symptoms:
The BIG-IP system might fail to re-establish an IKEv1 phase 1 security association (ISAKMP-SA) when the Initiator starts the exchange using UDP port 4500. The exchange progresses to the point of NAT detection, whereupon the BIG-IP system stops using the Non-ESP marker and sends malformatted ISAKMP.

Conditions:
All of the following must be true:
-- The BIG-IP system is an IKEv1 Responder.
-- ISAKMP phase 1 negotiation starts on UDP port 4500.
-- NAT is detected on only one side during the phase 1 exchange.

Impact:
-- Establishment of an ISAKMP-SA will fail until the peer device switches to UDP port 500.
-- The remote peer may send INVALID-SPI messages quoting SPI numbers that do not exist.

Workaround:
To help workaround this issue, you can try the following:
-- Make sure the BIG-IP system is always the Initiator.
-- Bypass NAT.
-- Configure both the BIG-IP system and remote peer to use address IDs that are not the same as the IP addresses used in the ISAKMP exchange, thus causing the BIG-IP system to think there is NAT on both sides.

Fix:
The BIG-IP system now keeps the Non-ESP marker when NAT is detected.

737389 : kern.log contains many messages: warning kernel: Tracklist initialized; Tracklist destroyed

Component: TMOS

Symptoms:
There may be a large number of messages in /var/log/kern.log similar to the following:

Tracklist initialized
Tracklist destroyed

Conditions:
This can happen when vCMP is provisioned, which enables SR-IOV mode.

Impact:
It causes messages to show up in /var/log/kern.log, but does not affect traffic. This is a cosmetic issue and does not indicate a functionality issue.

Workaround:
None.

Fix:
Tracklist is now disabled, so this issue no longer occurs.

737332-2 : It is possible for DNSX to serve partial zone information for a short period of time

Component: Global Traffic Manager (DNS)

Symptoms:
During zone transfers into DNS Express, partial zone data may be available until the transfer completes.

Conditions:
-- Two zones being transferred during the same time period
+ zone1.example.net
+ zone2.example.net

-- Transfer of zone1 has started, but not finished.

-- zone2 starts a transfer and finishes before zone1 finishes, meaning that the database might be updated with all of the zone2 data, and only part of the zone1 data.

Impact:
Partial zone data will be served, including possible NXDOMAIN or NODATA messages. This happens until zone1 finishes and saves to the database, at which time both zones' data will be complete and correct.

Workaround:
The workaround is to limit the number of concurrent transfers to 1. However this severely limits the ability of DNS Express to update zones in a timely fashion if there are many zones and many updates.

Fix:
All zone transfers are now staged until they are complete. The zone transfer data is then saved to the database. Only when the zone data has completed updating to the database will the data be available to queries.

735832-2 : RAM Cache traffic fails on B2150

Component: Performance

Symptoms:
Rendering pages from RAM Cache fails. System does not pass RAM Cache traffic on B2150 platform.

Conditions:
-- VIPRION B2150 blade.
-- Attempting to pass traffic from RAM Cache.

Impact:
B2150 does not pass any RAM Cache traffic.

Workaround:
None.

Fix:
RAM Cache traffic now succeeds on B2150.

735565-3 : BGP neighbor peer-group config element not persisting

Component: TMOS

Symptoms:
neighbor peer-group configuration element not persisting after restart

Conditions:
- dynamic routing enabled
- BGP neighbor configured with peer-group
- BIG-IP or tmrouted daemon restart

Impact:
BGP peer-group configuration elements don't persist

Workaround:
Reconfigure BGP neighbor peer-group after restart

Fix:
BGP neighbor peer-group configuration is properly save to configuration, and persists after restart

734622 : Policy change with newly enforced signatures causes sig collection failure in other policies

Solution Article: K83093212

Component: Application Security Manager

Symptoms:
An ASM policy change with newly enforced signatures causes a signature collection failure in all other policies.

Conditions:
An ASM policy is changed by adding newly enforced signatures.

Impact:
Signature collection failures are logged for all other policies.

Workaround:
For each other policy on the device, make a spurious change (such as modifying policy description and saving) and apply the policy. Alternatively, a new user-defined signature which would be included in enforcement can be spuriously added and then immediately removed.

734539-2 : The IKEv1 racoon daemon can crash on multiple INVALID-SPI payloads

Component: TMOS

Symptoms:
When an IKEv1 peer sends an INVALID-SPI payload, and BIG-IP system cannot find the phase-two Security Association (SA) for that SPI but can find phase-one SA involved; the racoon daemon may crash if there are additional INVALID-SPI payloads afterward.

Conditions:
-- An INVALID-SPI notification is received.
-- That phase-two SA is already gone.
-- The phase-one parent SA is still around.
-- Subsequent notification INVALID-SPI payloads involve the same phase-one SA.

Impact:
The v1 racoon daemon cores, interrupting traffic until new tunnels can be established after racoon restarts.

Workaround:
There is no workaround at this time.

Fix:
The system no longer destroys the parent phase-one SA when an INVALID-SPI notification cannot find the target phase-two SA, so this issue does not occur.

734527-4 : BGP 'capability graceful-restart' for peer-group not properly advertised when configured

Component: TMOS

Symptoms:
BGP neighbor using peer-group with 'capability graceful-restart' enabled (which is the default). However, on the system, peer-group defaults to disable. Because there is no config statement to enable 'capability graceful-restart' after restart, it gets turned off after config load, which also turns it off for any BGP neighbor using it.

Conditions:
- Neighbor configured to use peer-group.
- Peer-group configured with capability graceful-restart, but with the default: disabled.

Impact:
Because peer-group is set to disable by default, and there is no operation to enable it after restart, 'capability graceful-restart' gets turned off after config load, and neighbors using it from peer-group get turned off as well.

Workaround:
Re-issue the commands to set peer-group 'capability graceful-restart' and 'clear ip bgp *' to reset BGP neighbors.

Fix:
The peer-group now has 'capability graceful-restart' enabled by default, so this issue no longer occurs.

Behavior Change:
In this release, peer-group has 'capability graceful-restart' enabled by default.

734446-3 : TMM crash after changing LSN pool mode from PBA to NAPT

Component: Carrier-Grade NAT

Symptoms:
TMM crashes after changing LSN pool mode from PBA to NAPT when long lived connections are killed due to the PBA block lifetime and zombie timeout expiring.

Conditions:
An LSN pool using PBA mode with a block lifetime and zombie timeout set and long lived connections.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Instead of changing the LSN pool mode from PBA to NAPT, create a new LSN pool configured for NAPT and change the source-address-translation pool on the virtual servers that use the PBA pool.

The PBA pool can be deleted after the virtual servers are no longer using it.

Fix:
TMM no longer crashes after changing LSN pool mode from PBA to NAPT.

727292-2 : SSL in proxy shutdown case does not deliver server TCP FIN

Component: Local Traffic Manager

Symptoms:
Connection is not torn down.

Conditions:
HTTPS server disconnects connection when in handshake.

Impact:
Potential resource exhaustion.

Workaround:
You can mitigate this condition in either of the following ways:

-- Wait for system to clean up lingering connections.

-- Use tmsh to clean up connections. (Note: Sometimes this might not work as expected depending on conditions.)

-- If this happens on the config-sync channel, use a different self-ip for config-sync on the affected device.

Fix:
SSL server side handles this error situation by sending out all remaining egress data and sending a shutdown signal to lower filters.

727206-4 : Memory corruption when using SSL Forward Proxy on certain platforms

Component: Local Traffic Manager

Symptoms:
When using SSL Forward proxy, memory corruption can occur, which can eventually lead to a tmm crash.

Conditions:
Client SSL profile on a virtual server with SSL Forward proxy enabled.

-- Using the following platforms:
   - vCMP host
   - 2000s / 2200s
   - 5000s / 5200v
   - 5050s / 5250v / 5250v-F
   - 10350V-F

Impact:
TMM crash. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
TMM no longer crashes under these conditions.

726895-1 : VPE cannot modify subroutine settings

Solution Article: K02205915

Component: Access Policy Manager

Symptoms:
Open per-request policy in Visual Policy Editor (VPE) that has a subroutine. Click 'Subroutine Settings / Rename.

Numeric values like the inactivity timeout are displayed as 'NaN. Attempts to modify the values results in MCP validation errors such as one of these:
- Unable to execute transaction because of:
- Unable to execute transaction because of: 01020036:3: The requested user role partition (admin Common) was not found.

Conditions:
-- Per-request policy in the VPE.
-- Subroutine in the per-request policy.
-- Attempt to change the values.

Impact:
All fields say 'NaN', and error when trying to modify properties. Subroutine settings like the Inactivity Timeout and Gating Criteria cannot be modified through the VPE

Workaround:
Use tmsh to modify these values, for example:

tmsh modify apm policy access-policy <policy_name> subroutine properties modify { all { inactivity-timeout 301 } }

Fix:
The issue has been fixed; it is now possible to view and modify subroutine settings in the VPE.

726647-1 : PEM content insertion in a compressed response may truncate some data

Component: Policy Enforcement Manager

Symptoms:
HTTP compressed response with content insert action can truncate data.

Conditions:
PEM content insertion action with compressed HTTP response.

Impact:
Data might be truncated.

Workaround:
There is no workaround other than disabling compression accept-encoding attribute in the HTTP request.

Fix:
HTTP compressed response with content insert action no longer truncates data.

726592-2 : Invalid logsetting config messaging between our daemons could send apmd, apm_websso, localdbmgr into infinite loop

Component: Access Policy Manager

Symptoms:
Invalid logsetting config messaging between our daemons could send apmd, apm_websso, localdbmgr into infinite loop. This could be triggered by invalid state of our control plane daemons.

Conditions:
This is an extremely rare situation that can be caused by invalid logsetting config messaging between our daemons. However, once it happens it can impact multiple daemons at the same time causing all of them to hang.

Impact:
Once this happens it can impact multiple daemons (apmd, apm_websso, localdbmgr) at the same time causing all of them to hang.

Workaround:
There is no workaround at this time, you can recover by restarting the daemons that hang.

Fix:
We have fixed a memory corruption that can break the linkages in our data structure which would cause certain traversals to loop indefinitely.

726487-1 : MCPD on secondary VIPRION or vCMP blades may restart after making a configuration change.

Component: TMOS

Symptoms:
The MCPD daemon on secondary VIPRION or vCMP blades exits and restarts, logging errors similar to the following:

-- err mcpd[11869]: 01070734:3: Configuration error: Node name /group1/5.5.5.5 encodes IP address 5.5.5.5%18 which differs from supplied address field 5.5.5.5.

-- err mcpd[11869]: 01070734:3: Configuration error: Configuration from primary failed validation: 01070734:3: Configuration error: Node name /group1/5.5.5.5 encodes IP address 5.5.5.5%18 which differs from supplied address field 5.5.5.5... failed validation with error 17237812.

Or:

--- err mcpd[8320]: 0107003b:3: Pool member IP address (5.5.5.5%999) cannot be assigned to node (/group1/node1). The node already has IP address (5.5.5.5).

--- err mcpd[8320]: 01070734:3: Configuration error: Configuration from primary failed validation: 0107003b:3: Pool member IP address (5.5.5.5%999) cannot be assigned to node (/group1/node1). The node already has IP address (5.5.5.5).... failed validation with error 17236027.

Conditions:
This issue occurs when all of the following conditions are met:

-- VIPRION or vCMP platform with more than one blade.
-- A partition with a non-default route domain.
-- Creating a pool member in the aforementioned partition while a configuration save is taking place at the same time (either system or user initiated).

Impact:
If the system is Active, traffic will be disrupted as the secondary blades restart. The capacity of the system will be reduced until all blades are on-line again. Additionally, depending on the system configuration, the system may fail over to its peer (if one exists).

Workaround:
There is no workaround other than not to create pool members from a different client while saving configuration changes in another client. However, this does not help if the configuration save operation was system-initiated.

Fix:
MCPD on secondary blades no longer restarts if a pool member is created in a partition that uses a non-default route domain at the same as the configuration is being saved.

726412-1 : Virtual server drop down missing objects on pool creation

Component: Global Traffic Manager (DNS)

Symptoms:
Available virtual servers are not populated in the drop down list during Pool creation.

Conditions:
Virtual server names containing single quote, backslash, or greater-than and less-than signs: ' \ < >.

Impact:
Unable to add available virtual servers to pools.

Workaround:
After pool creation, go into that newly created pool, click 'Members', and then click 'Manage', and use the Virtual Server drop-down list to add any virtual servers.

Fix:
Fixed the drop down for virtual servers. Now virtual servers get loaded in the drop-down list during pool creation.

Component: Traffic Classification Engine

Symptoms:
Cannot add more than 10 million custom db entries.

Conditions:
This happens when you try to add more than 10 million custom db entries.

Impact:
Not able to add more than 10 million entries.

Workaround:
There is no workaround at this time.

Fix:
This release provides a sys db var, tmm.urlcat.no_db_limit, to allow growth beyond the existing limit of 10 million custom db entries.

726255-3 : dns_path lingering in memory with last_access 0 causing high memory usage

Component: Global Traffic Manager (DNS)

Symptoms:
dns_path not released after exceeding the inactive path ttl.

Conditions:
1. Multiple tmm's in sync group
2. Multiple dns paths per GTM needed for load balancing.

Impact:
High memory usage.

Workaround:
There is no workaround at this time.

Fix:
dns_path memory will be released after ttl.

726239-3 : interruption of traffic handling as sod daemon restarts TMM

Component: Local Traffic Manager

Symptoms:
When the receiving host in a TCP connection has set its send window to zero (stopping the flow of data), following certain unusual protocol sequences, the logic in the TMM that persists in probing the zero window may enter an endless loop.

Conditions:
When the TCP implementation is probing a zero-window connection under control of a persist timer.

Impact:
Lack of stability on the device. Traffic disrupted while tmm restarts.

Workaround:

726089-3 : Modifications to AVR metrics page

Solution Article: K44462254

724868-2 : dynconfd memory usage increases over time

Component: Local Traffic Manager

Symptoms:
dynconfd memory usage slowly increases over time as it processes various state-related messages.

Conditions:
No special conditions as dynconfd is a core LTM process. Large numbers of pool members combined with flapping might increase the rate of memory usage increase.

Impact:
dynconfd grows over time and eventually the system is pushed into swap. Once swap is exhausted, the Linux OOM killer might terminate critical system processes, disrupting operation.

Workaround:
Periodic restarts of dynconfd avoids the growth affecting the system.

Fix:
dynconfd no longer leaks memory when processing messages.

724214-2 : TMM core when using Multipath TCP

Component: Local Traffic Manager

Symptoms:
In some cases, TMM might crash when processing MPTCP traffic.

Conditions:
A TCP profile with 'Multipath TCP' enabled is attached to a virtual server.

Impact:
Traffic interrupted while TMM restarts.

Workaround:
There is no workaround other than to disable MPTCP.

Fix:
TMM no longer produces a core.

723794-4 : PTI (Meltdown) mitigation should be disabled on AMD-based platforms

Component: TMOS

Symptoms:
Platforms with AMD processors freeze when the PTI (Page Table Isolation) mitigation is enabled, after a period ranging from several hours to several days.

You can find information about which versions have the PTI (Meltdown) mitigations enabled in the AskF5 Article: Bug ID 707226: DB variables to disable CVE-2017-5754 Meltdown/PTI mitigations :: https://cdn.f5.com/product/bugtracker/ID707226.html.

Conditions:
-- AMD-based platforms:
   + BIG-IP B4100 blades
   + BIG-IP B4200 blades
   + BIG-IP 6900 and NEBS appliances
   + BIG-IP 89x0 appliances
   + BIG-IP 6400 FIPS and NEBS platforms
   + BIG-IP 110x0 appliances

-- The database variable kernel.pti is set to enable (to address PTI (Meltdown)).

Impact:
System locks up and is rebooted by the watchdog timer.

Workaround:
Set the database variable kernel.pti to disable by running the following command:

tmsh modify sys db kernel.pti value disable

According to AMD, these AMD processors are not vulnerable to PTI (Meltdown), so there is no reason to leave the db variable enabled.

Fix:
PTI (Page Table Isolation) mitigation is no longer enabled on AMD-based platforms.

723792-3 : GTM regex handling of some escape characters renders it invalid

Component: Global Traffic Manager (DNS)

Symptoms:
The memory footprint of big3d increases.

Conditions:
GTM monitor recv string such as the following: ^http\/\d\.\d[23]\d\d

Impact:
Escaped characters are mishandled. This causes the regex compilation to fail and leak memory. The monitor marks the server it is monitoring UP as long as the server returns any response.

Workaround:
If you notice big3d memory footprint increase and you have a monitor recv string that has escaped characters such as '^http\/\d\.\d[23]\d\d', try changing the recv string to something similar to the following: ^HTTP/[0-9][.][0-9] [23][0-9]{2}

Fix:
Fixed handling of escape characters. Recv strings that previously failed to compile will now compile.

723790-4 : Idle asm_config_server handlers consumes a lot of memory

Component: Application Security Manager

Symptoms:
Idle asm_config_server handlers needlessly uses a large amount of memory.

Conditions:
This issue might result from several sets of conditions. Here is one:

Exporting a big XML ASM policy and then leaving the BIG-IP system idle. Relevant asm_config_server handler process increases its memory consumption and stays that way, holding on to the memory until it is released with a restart.

Impact:
Unnecessary memory consumption.

Workaround:
1) Lower the MaxMemorySize threshold from 450 MB to 250 MB, per process of asm_config_server:
---------------
# perl -pi.bak -e 's/MaxMemorySize=471859200/MaxMemorySize=262144000/' /etc/ts/tools/asm_config_server.cfg
---------------

2) Restart asm_config_server, to free up all the memory that is currently taken by all asm_config_server processes and to impose the new MaxMemorySize threshold:
---------------
# pkill -f asm_config_server
---------------

Notes:
-- The provided workaround does not permanently fix the issue. Instead it alleviates the symptoms of memory pressure, by (1) lowering the MaxMemorySize threshold from 450 MB to 250 MB, per process of asm_config_server, and (2) freeing up all the memory that is currently taken by all asm_config_server processes.
-- This workaround does not cause any down time; the asm_config_server processes automatically start within ~30 seconds.

723722-3 : MCPD crashes if several thousand files are created between config syncs.

Component: TMOS

Symptoms:
If more than several thousand (typically 20,000, but number varies by platform) files, for example SSL certificates or keys, are created between config syncs, the next config sync operation will take too long and mcpd will be killed by sod.

Conditions:
Creation of several thousand SSL certificates or keys followed by a config sync operation.

Impact:
Traffic is disrupted while the MCPD process restarts.

Workaround:
Run a config sync operation after every ~5000 files created.

Fix:
MCPD no longer crashes if several thousand files are created between config sync operations.

723298-3 : BIND upgrade to version 9.11.4

Component: TMOS

Symptoms:
The BIG-IP system is running BIND version 9.9.9.

Conditions:
BIND on BIG-IP system.

Impact:
BIND 9.9 Extended Support Version was supported until June, 2018.

Workaround:
None.

Fix:
BIND version has been upgraded to 9.11.4.

723288-3 : DNS cache replication between TMMs does not always work for net dns-resolver

Component: Global Traffic Manager (DNS)

Symptoms:
System DNS resolvers (net dns-resolver objects) do not share DNS reply information between the dns resolver instances across TMMs, which can result in separate TMMs performing seemingly-unnecessary DNS lookups.

Conditions:
There are no LTM DNS *cache* objects present in the BIG-IP configuration.

Impact:
A performance impact resulting from each TMM having to perform unnecessary DNS lookups.

Workaround:
Use tmsh to create a placeholder LTM DNS cache resolver object. The object does not need to be used anywhere, just present in the config.

Note: This workaround is effective even without a DNS license (although in that case, the placeholder object must be created using tmsh, as the GUI menu would not be available without a DNS license.)

723130-3 : Invalid-certificate warning displayed when deploying BIG-IP VE OVA file

Solution Article: K13996

Component: TMOS

Symptoms:
The OVA signing certificate that signs BIG-IP Virtual Edition (VE) OVA files expired. When deploying a BIG-IP VE from an OVA file, an invalid-certificate warning might be displayed due to the expired OVA signing certificate.

Conditions:
This issue may be encountered during the creation of new instances of BIG-IP VE in clients that check the validity of the OVA signing certificate (e.g., VMware).

Note: Existing BIG-IP VE instances are not subject to this issue.

Impact:
There might be questions about the integrity of the OVA file, and in some cases, might not be able to deploy a new instance from an OVA file.

Workaround:
None.

Fix:
The expired OVA signing certificate has been replaced with a valid signing certificate.

722969-1 : Access Policy import with 'reuse' enabled instead rewrites shared objects

Component: Access Policy Manager

Symptoms:
If a policy is exported and then imported with 'reuse' it rewrites objects on the server instead of simply reusing them.

Conditions:
-- Exporting profile A.
-- Importing profile B, with 'reuse' configured.
-- The objects in both profiles are named the same and are the same type.

Impact:
-- 'Reused' objects on the system are modified.
-- Policy A requires 'apply', because objects shared with Policy B are overwritten.

Workaround:
None.

Fix:
Access policy import with 'reuse' option enabled no longer rewrites shared objects

722682-1 : Fix of ID 615222 results in upgrade issue for GTM pool member whose name contains a colon; config failed to load★

Component: TMOS

Symptoms:
Loading configuration process failed after upgrade when pool member names contain colons. The system posts errors similar to the following:
01070226:3: Pool Member 443:10.10.10.10 references a nonexistent Virtual Server
Unexpected Error: Loading configuration process failed.

Conditions:
-- GTM pool member has colon in its name.
-- Upgrade to any of the following versions:
  + 12.1.3.x
  + Any 13.0.x
  + All 13.1.x earlier than 13.1.1.2
  + 14.0.x earlier than 14.0.0.3

Impact:
The system removes the part of the pool member name that precedes the colon, and configuration load fails. For example, when the configuration contains a pool member named example_pm:443:10:10:10:10, the system removes the part of the pool member name that precedes the first colon, in this case, example_pm, leaving the pool member name 443:10.10.10.10.

Workaround:
After upgrade, add two backslash characters, \\ before the first colon, : character.

1. Upgrade the BIG-IP DNS system to the new version of software.
2. SSH to log into the bash prompt of the BIG-IP DNS system.
3. Run the following command to add the string \\ in front of the first colon character, : in the name of each affected GTM pool member:

for j in $(find /config/ -name bigip_gtm.conf); do for i in $(awk '$0 ~ /^gtm server.*:/ {gsub("[/:]"," ",$0); print $4}' ${j}); do sed -i "s, /Common/${i}, /Common/${i}\\\\\\\,g" ${j} | grep " /Common/${i}"; done; done

4. Run the following command: load sys config gtm-only

Fix:
Configuration load no longer fails when upgrading with a configuration that contains BIG-IP DNS pools with members whose names contain colon characters.

Solution Article: K64208870

722013-3 : MCPD restarts on all secondary blades post config-sync involving APM customization group

Component: Access Policy Manager

Symptoms:
After performing a series of specific config-sync operations between multi-blade systems, the MCPD daemon restarts on all secondary blades of one of the systems.

Each affected blade will log an error message similar to the following example:

-- err mcpd[5038]: 01070711:3: Caught runtime exception, Failed to collect files (snapshot path () req (7853) pmgr (7853) not valid msg (create_if { customization_group { customization_group_name "/Common/Test-A_secure_access_client_customization" customization_group_app_id "" customization_group_config_source 0 customization_group_cache_path "/config/filestore/files_d/Common_d/customization_group_d/:Common:Test-A_secure_access_client_customization_66596_1" customization_group_system_path "" customization_group_is_system 0 customization_group_access 3 customization_group_is_dynamic 0 customization_group_checksum "SHA1:62:fd61541c1097d460e42c50904684def2794ba70d" customization_group_create_time 1524643393 customization_group_last_update_time 1524643393 customization_group_created_by "admin" customization_group_last_updated_by "admin" customization_group_size 62 customization_group_mode 33188 customization_group_update_revision 1

Conditions:
This issue occurs when all of the following conditions are met:

- You have configured a device-group consisting of multi-blade systems (such as VIPRION devices or vCMP guests).

- Systems are provisioned for APM.

- The device-group is configured for incremental manual synchronizations.

- On one system (for example, source_system), you create an APM configuration object (for example, a connectivity profile) that causes the automatic creation of an associated customization group.

- You synchronize the configuration from the source_system to the device-group.

- On the source_system, you create a new configuration object of any kind (for example, an LTM node).

- Instead of synchronizing the newest configuration to the device-group, you synchronize the configuration from another device in the device-group to the source_system (which effectively undoes your recent change).

- The MCPD daemon restarts on all secondary blades of the source_system.

Impact:
While the MCPD daemon restarts, the blade is offline, and many other BIG-IP daemons need to restart along with MCPD.

-- If the source_system is Active, the load capacity of the system temporarily decreases proportionally to the number of blades restarting. Additionally, if the systems use the min-up-members or HA-Group features, losing a certain number of secondary blades may trigger a failover.

-- If the source_system is Standby, some of the previously mirrored information may become lost as TMM on secondary blades restarts along with MCPD. Should this system later become the Active system, traffic may be impacted by the lack of previously mirrored information.

Workaround:
None.

Fix:
The MCPD daemon no longer restarts on secondary blades after config-sync of APM.

721924-3 : bgpd may crash processing extended ASNs

Solution Article: K17264695

Component: TMOS

Symptoms:
Under certain conditions bgpd may crash while processing extended ASNs.

Conditions:
Dynamic routing enabled.
Extended ASP capabilities enabled: bgp extended-asn-cap enabled

Impact:
Dynamic routing disrupted while bgpd restarts.

Fix:
bgpd now processes extended ASNs as expected.

721895-1 : Add functionality to configure the minimum TLS version advertised and accepted by big3d (iQuery)

Component: Global Traffic Manager (DNS)

Symptoms:
big3d advertises a TLSv1.0 version. Even though big3d requires previously exchanged certificates to validate a connection request, the TLSv1.0 advertisement triggers various vulnerability scanners and is flagged.

Conditions:
Running a vulnerability scanner or other SSL test tool.

Impact:
The scanner or tool reports that big3d might potentially accept a TLSv1.0 connection request (which is considered insecure). Vulnerability scanners then flag the BIG-IP system as vulnerable.

Workaround:
Although there is no workaround, because big3d accepts connections only from clients that match the certificates on the BIG-IP system, the risk is minimal.

In addition, you can deploy firewall rules to accept connections only on port 4353 from know BIG-IP systems.

Fix:
This version adds a db variable for the big3d
big3d.minimum.tls.version. By default the value is 'TLSv1'. You can also specify TLSV1.1 or TLSV1.2 (the setting is case insensitive).

After changing the DB variable, restart big3d. Change the value on all BIG-IP systems that are subject to scans. This includes GTM as well as LTM configurations.

Conditions:
Configuring IP Address Exceptions in certain order - w/ and w/o route domain.

Impact:
BD and BD_Agent out-of-sync for IP Address Exception, causes false positives / false negatives

Workaround:
There is no workaround at this time.

Fix:
System no longer generates these false positive/negative log entries.

721621-2 : Ephemeral pool member is not created/deleted when DNS record changes and IP matches static node

Component: Local Traffic Manager

Symptoms:
If an LTM pool is configured with only FQDN members, the DNS server resolves the FQDN to IP addresses that match statically-configured LTM nodes, and the IP address records returned by the DNS server change, an ephemeral pool member may not be added to the pool for the new IP address.

When in this state, if the FQDN template pool member is deleted from the pool, a new ephemeral pool member may be added corresponding to the last IP address record returned by the DNS server.

Conditions:
This may occur when:
1. Static nodes are configured which match addresses that may be returned in the DNS query for a given FQDN name.
2. An FQDN node is created with autopopulate disabled, for an address which may resolve to the same address as one of the static nodes.
3. This FQDN node is added (as a pool member) with autopopulate disabled, to a pool with no other non-FQDN members.
4. The DNS server resolves the FQDN name to an address that matches one of the static nodes.
5. A subsequent DNS query resolves the FQDN name to a different address that matches a different static node.

Impact:
In this case:
-- The original ephemeral member is removed from the pool.
-- A new ephemeral member for the new address may NOT be added to the pool.
-- In this state, if the FQDN template member is deleted from the pool, a new ephemeral member (i.e., the missing ephemeral with new IP address) is re-added to the pool.

Note. This symptom can occur only if the statically-configured node is created prior to an ephemeral pool member being created for the same IP address. If an ephemeral pool member and node are created first, it is not possible to create a statically-configured node or pool member using the same IP address.

Overall, traffic for the affected pool may not be sent to correct pool member (new ephemeral address).

If no other members are defined in the pool, traffic will be interrupted.

Workaround:
This issue can be prevented by:
-- Avoiding configuring a static (non-FQDN) node with an IP address that matches any address that might be returned by the DNS server when resolving the FQDN.
-- Adding a statically-configured pool member to the pool in addition to the FQDN template member.

Once the symptom occurs, recovery is possible by performing either of the following actions:
-- Delete the statically-configured node with the conflicting IP address.
-- Recreate the node using the following procedure:
1. Delete the FQDN template member from the pool.
2. Delete the orphaned ephemeral member from the pool.
3. Re-add the FQDN template member to the pool.

Fix:
When an FQDN pool member address resolves to the same IP address as an existing static node, the corresponding ephemeral pool member is successfully created and deleted as expected, including when the IP address returned by the DNS query changes.

721399-3 : Signature Set cannot be modified to Accuracy = 'All' after another value

Component: Application Security Manager

Symptoms:
ASM Signature Set cannot be modified to Accuracy = 'All' after another value was used previously.

Conditions:
-- ASM Signature Set has a value set for Accuracy filter.
-- Accuracy is subsequently set to 'All'.

Impact:
The change to Accuracy = 'All' does not take effect. ASM Signature Set cannot be modified to Accuracy = 'All'.

Workaround:
You can use either of the following workarounds:

-- Delete and re-create the Signature Set with the desired value.
-- Modify the filter to a value that will match all results (such as Accuracy is greater than or equal to 'Low').

Fix:
ASM Signature Set can now be set to Accuracy = 'All' after a value was previously set.

721375 : Export then import of config with RSA server in it might fail

Component: Access Policy Manager

Symptoms:
If an exported policy configuration contains both an RSA server as well as the RSA-provided sdconf.rec and sdstatus.12 config files, policy import might fail.

Conditions:
-- RSA server and access profile are in the same, non-Common partition.
-- Exported policy contains an RSA server as well as both the RSA-provided sdconf.rec and sdstatus.12 config files.

Impact:
Unable to import the exported configuration. This occurs because of how the names for the files are resolved in the exported configuration.

Workaround:
Although there is no actual workaround, you can avoid this issue if the profile is outside of the partition. That case uses a different name resolution during the export, so import works as expected.

Fix:
You can now successfully import an exported policy containing an RSA server as well as both sdconf.rec and sdstatus.12 files.

720880 : Attempts to license/re-license the BIG-IP system fail.

Component: TMOS

Symptoms:
Attempts to activate or reactivate the license on the BIG-IP system results in failure messages.

Conditions:
No specific configurations are associated with this issue, but license activation/reactivation requests that include add-ons are more likely to fail.

This occurs under random conditions.

Impact:
The system is either unusable or very difficult to activate.

Workaround:
Because the conditions under which this issue occurs are random, additional licensing attempts might succeed.

Fix:
The source of the underlying problem has been corrected. No additional logs, error message, or user-interaction is involved.

720819-1 : Certain platforms may take longer than expected to detect and recover from HSB lock-ups

Component: TMOS

Symptoms:
In the unlikely event of a HSB lock-up, certain BIG-IP platforms may take longer than expected to detect and recover from the condition.

For instance, it may take several minutes for an affected unit to detect the condition and initiate the predefined failsafe action.

Instead, the recovery mechanism should trigger almost instantaneously.

Conditions:
This issue occurs when all of the following conditions are met:

-- The BIG-IP system is an i56xx/i58xx, i76xx/i78xx, or i106xx/i108xx platform.

-- The HSB locks-up due to a different issue.

Impact:
Traffic is negatively impacted until the BIG-IP system detects and remedies the condition. This might take up to 15 minutes before remedied by a reboot, depending on other traffic being processed.

Workaround:
None.

Fix:
The HSB lock-up is now promptly detected and remedied.

720799-3 : Virtual Server/VIP flaps with FQDN pool members when all IP addresses change

Component: Local Traffic Manager

Symptoms:
When using FQDN pool members, if all ephemeral members are removed and replaced by a DNS query that returns an entirely new set of IP addresses (no overlap with previous DNS query results), all ephemeral pool members are removed before the new ephemeral pool members are created.

This results in a brief moment when there are no ephemeral members (that can receive traffic) in the pool.

Conditions:
A DNS query for the FQDN node in which the pool members belong, returns an entirely new set of IP addresses (no overlap with previous DNS query results).

Impact:
The brief moment during which there are no ephemeral members (that can receive traffic) in the pool can cause a Virtual Server or Virtual Address using that pool to flap.

Workaround:
It is possible to work around this issue by:
1. Adding a pool member with a statically-configured IP address.
2. Including multiple FQDN pool members in the pool, to limit the effect of the ephemeral members changing for a single FQDN pool member.

Fix:
When using FQDN pool members, ephemeral members whose IP addresses are not present in the most DNS query results are not immediately deleted from the pool.

To prevent the brief condition in which there are no ephemeral members in the pool (which can cause a Virtual Server or Virtual Address using that pool to flap), creation of new ephemeral nodes and pool members occurs immediately, but deletion of old new ephemeral nodes and pool members occurs after a delay.

The duration of the delay follows the fqdn 'down-interval' value configured for the associated FQDN template node.

720756 : SNMP platform name is unknown on i11400-DS/i11600-DS/i11800-DS

Component: TMOS

Symptoms:
The SNMP query for platform marketing name is 'unknown' for i11400-DS/i11600-DS/i11800-DS.

Conditions:
-- On licensed system, check OID marketing name.
-- Using i11400-DS/i11600-DS/i11800-DS platforms.

Impact:
Cannot tell the actual platform name in the SNMP query.

Workaround:
There is no workaround at this time.

Fix:
SNMP platform name is now reported correctly on BIG-IP i11400-DS/i11600-DS/i11800-DS platforms.

720713-3 : TMM traffic to/from a i5800/i7800/i10800 device in vCMP host mode may fail

Component: TMOS

Symptoms:
When a BIG-IP iSeries i5800, i7800, or i10800 device is configured as a vCMP host and at least one vCMP guest is running (or ever ran), TMM traffic to the vCMP host may fail.

Note: Management port traffic to/from the device is unaffected.

Note: TMM traffic to/from the vCMP guests running on the device is unaffected. This issue affects only the vCMP host.

The most visible symptom is that TMM on the vCMP host fails to answer ARP requests that it receives for its own Self-IP addresses.

Conditions:
This issue occurs when all of the following conditions apply:

- BIG-IP iSeries i5800, i7800, or i10800 device in vCMP host mode.

- At least one vCMP guest is deployed or was deployed, at some point.

Impact:
Inability to communicate to/from the vCMP host via its Self-IP addresses.

Workaround:
Ensure that the host is running a compatible version of BIG-IP. For more information on supported host/guest versions, see K14088: vCMP host and compatible guest version matrix, available at https://support.f5.com/csp/article/K14088

Fix:
The vCMP host continues to handle traffic correctly once a guest is started.

720695-2 : Export then import of APM access Profile/Policy with advanced customization is failing

Component: Access Policy Manager

Symptoms:
An exported policy containing advanced customization fails to import.

Conditions:
-- Export policy containing advanced customization.
-- Import the same policy.

Impact:
Import fails.

Workaround:
None.

Fix:
Access policy import containing advanced customization now succeeds.

720651-3 : Running Guest Changed to Provisioned Never Stops

Component: TMOS

Symptoms:
After changing a vCMP guest status to provisioned the guest remains running showing a status of stopping.

Conditions:
-- Guests deployed on a BIG-IP VCMP host.
-- Changing the state from deployed to provisioned.

Impact:
Guests do not stop and change status until vcmpd process is restarted.

Workaround:
There is no workaround.

Fix:
The guest now stops when the state is changed from deployed to provisioned.

720461-3 : qkview prompts for password on chassis

Component: TMOS

Symptoms:
Qkview prompts for a password when executing getnodedates from the chassis module.

Conditions:
SSH auth keys are missing or corrupted.

Impact:
This blocks collecting qkview.

Workaround:
Edit the /user/bin/getnodedates script and add -oBatchMode=yes for the SSH command as shown in the following example:

$date = `/usr/bin/ssh -q -oBatchMode=yes -oStrictHostKeyChecking=no $ip /bin/date`;

Fix:
The qkview is no longer blocked with a password prompt.

720391-1 : BIG-IP i7800 Dual SSD reports wrong marketing name under 'show sys hardware'

Component: TMOS

Symptoms:
BIG-IP i7800 Dual SSD reports wrong marketing name under 'show sys hardware' and 'unknown' when OID sysObjectID is queried.

Conditions:
1. Execute 'tmsh show sys hardware'.
2. Query for OID sysObjectID using snmpwalk.

Impact:
System is reported as 'none', when it should be i7800-D. Platform with dual SSD not correctly identified using tmsh command or snmpwalk.

Workaround:
None.

Fix:
Added new SNMP OID for BIG-IP i7800 Dual SSD, reported as BIG-IP i7800-D, which is the correct designation.

720293-1 : HTTP2 IPv4 to IPv6 fails

Component: Local Traffic Manager

Symptoms:
An IPv4-formatted virtual server with an IPv6-formatted pool member cannot establish the connection to the pool member if HTTP2 is configured.

Conditions:
-- IPv4 virtual Server.
-- IPv6 pool member.
-- HTTP2 profile.

Impact:
Traffic connection does not establish; no traffic passes.

Workaround:
None.

Fix:
In this release, an IPv4-formatted virtual server with an IPv6-formatted pool member works with HTTP2.

720269-3 : TACACS audit logging may append garbage characters to the end of log strings

Component: TMOS

Symptoms:
When using TACACS audit logging, you might see extra 'garbage' characters appended to the end of logging strings.

Conditions:
Using audit forwarding with a remote TACACS server.

Impact:
Confusing log messages. Remote TACACS logging might stop altogether after some time.

Workaround:
There is no workaround at this time.

Fix:
Prevented extra characters from being appended to TACACS audit logs.

720219-1 : HSL::log command can fail to pick new pool member if last picked member is 'checking'

Solution Article: K13109068

Component: Local Traffic Manager

Symptoms:
This occurs in certain configurations where the HSL::log command is using a remote high speed log (HSL) pool with failing pool members. If a pool member goes into a 'checking' state and the command attempts to send the log via that pool member, it can fail to send and all future log commands from that iRule will also fail, if that pool member is actually unavailable.

Conditions:
-- Using HSL::log command.
-- iRule with a remote high speed logging configured.

Impact:
Failure to send log messages via HSL.

Workaround:
Follow this procedure:
1. Change the 'distribution' method of the remote high speed config to something else.
2. Save the configuration.
3. Change the method back.

Fix:
This issue no longer occurs. If a 'down' pool member is picked, it will eventually be bypassed to find an 'up' pool member, if possible.

720110-4 : 0.0.0.0/0 NLRI not sent by BIG-IP when BGP peer resets the session.

Component: TMOS

Symptoms:
Neither learned nor default-originate default routes (0.0.0.0/0) are sent to the BGP peer if the BGP peer has terminated the BGP session with TCP FIN, without BGP notify message.

Conditions:
1. BGP session is terminated without BGP notify (just TCP FIN).
2. Either learned (not originated in DUT) and default-originate (originated in DUT) routes are not sent.

Impact:
Default routes are not propagated in the network after the BGP peer restart.

Workaround:
There is no workaround at this time.

Fix:
Default routes are now always sent after the BGP session reset. Consistent behavior between BGP session reset with and without BGP notify message.

720104 : BIG-IP i2800/i2600 650W AC PSU has marketing name missing under 'show sys hardware'

Component: TMOS

Symptoms:
BIG-IP i2800/i2600 650W AC PSU is missing marketing name under 'show sys hardware' and displays 'unknown' when OID sysObjectID is queried.

Conditions:
-- Execute 'tmsh show sys hardware'.
-- Query for OID sysObjectID using snmpwalk.
-- Using BIG-IP i2800/i2600 platforms.

Impact:
System reports an empty marketing name when queried. Platform with 650W AC PSU not identified using tmsh command or snmpwalk.

Workaround:
There is no workaround at this time.

Fix:
Added new SNMP OID for BIG-IP i2800/i2600 650W AC PSU.

720030-3 : Enable EDNS flag for internal Kerberos DNS SRV queries in Kerberos SSO (S4U)

Component: Access Policy Manager

Symptoms:
Kerberos DNS SRV requests are generated without enabling EDNS0. Without this, internal DNS server (dnscached) truncates the UDP response if it is greater than 512 bytes, causing the DNS request to be re-sent on TCP connections. This results in a lot of TIME_WAIT connections on the socket using dnscached.

Conditions:
APM end users using Kerberos SSO to access backend resources.

Impact:
Ability to create new DNS requests is affected, if there are numerous sockets in TIME_WAIT. This can result in scalability issues.

Workaround:
For BIG-IP software v12.x and later,

Edit the /etc/resolv.conf file to add an EDNS0 option.

There is no workaround if you are running a version earlier than 12.x.

Fix:
Kerberos DNS SRV requests now support EDNS0, so that UDP responses greater than 512 bytes can be received correctly, eliminating the need to re-send the request on TCP while communicating to the internal DNS server (dnscached).

719644-1 : If auto-discovery is enabled, GTM configuration may be affected after an upgrade from 11.5.x to later versions★

Component: Global Traffic Manager (DNS)

Symptoms:
When an LTM configuration has virtual server names containing period (.), a GTM configuration with auto-discovery enabled is upgraded from v11.5.x to a later version might lose consistency.

Conditions:
-- Upgrading GTM from v11.5.x to later versions (e.g., BIG-IP DNS v12.x).
-- Auto-discovery is enabled.
-- LTM configuration containing virtual server names containing the period character (.).
-- The same virtual server name is used in multiple partitions.

Impact:
The configuration after the upgrade might be affected in the following ways:
-- Missing virtual servers.
-- Deletion of some pool members.
-- Virtual servers with incorrect addresses.

Workaround:
There is no workaround at this time.

Fix:
This release supports GTM upgrades from 11.x to BIG-IP DNS 12.x and later versions for cases where:
-- Auto-discovery is enabled.
-- LTM virtual server name a period character (.).
-- The same virtual server name is used in multiple partitions.

719554-3 : Linux Kernel Vulnerability: CVE-2018-8897

Solution Article: K17403481

718885-1 : Under certain conditions, monitor probes may not be sent at the configured interval

Solution Article: K25348242

Component: Global Traffic Manager (DNS)

Symptoms:
When sufficient resources are configured with the same monitor interval, and the monitor timeout value is no more than two times the monitor interval, the monitored resource may be marked as unavailable (due to a timeout) then immediately changed to available.

Conditions:
Monitor interval is lower than the number of resources configured with the same monitor interval.

Impact:
Monitor probes are not consistently performed at the configured interval.

Workaround:
Set the monitor interval to a value greater than the number of resources monitored using that same interval value.

The key to this workaround is to ensure that the sum of the resources monitored at a given interval is not greater than the interval. That can be accomplished several ways depending on your configuration and requirements.

For example, if the monitoring interval is 30 seconds and there are 40 different monitors with a 30-second interval and each monitor is assigned to exactly one resource, there are at least two options:

-- Change the interval for 10 of the monitors to a different value.

-- Set the monitor interval to 40.

Note: If you change the monitor interval, make sure to also change the timeout value to follow best practices:
timeout value = (3 x interval) + 1.

Fix:
Monitoring is now consistently performed at the configured interval regardless of the number of resources with the same monitor interval.

718210-3 : Connections using virtual targeting virtual and time-wait recycle result in a connection being improperly reused

Component: Local Traffic Manager

Symptoms:
In very rare circumstances, connections that use virtual targeting virtual server and time-wait recycle result in a connection being improperly reused.

Conditions:
Virtual server targeting virtual server (usually occurs in an iRule) with time-wait recycle being used on the virtual server's TCP profile.

Note: This is the default value, so any virtual servers defined internally are using it.

Impact:
A connection might be reused even though it is a new one. TMM can crash and restart. Traffic disrupted while tmm restarts.

Note: This is an extremely rare issue.

Workaround:
None.

Fix:
This issue has been fixed.

718208-1 : Unable to install Network Access plugin on Linux Ubuntu 16.04 with Firefox v52 ESR using SUDO

Component: Access Policy Manager

Symptoms:
When using Firefox v52 ESR to install SVPN client, the SVPN client keeps prompting to enter SUDO credentials.

Conditions:
Using Firefox v52 ESR to install SVPN client.

Impact:
Cannot install SVPN client using Firefox v52 ESR browser.

Workaround:
Follow this procedure to work around this problem:

1. Delete the NPAPI plugin from the browser. To do so, remove the browser plugin, which you can find in either or both of the following locations:

~/.mozilla/plugins/np_F5_SSL_VPN_x86_64.so

~/.mozilla/firefox/w8wdvzyy.default/extensions/{5984e8a4-b593-11e5-ad1f-ac88bb8e7f8b}/

2. Launch the browser; connect to APM and install the SVPN client manually.
3. Install the plugin through the browser, or copy the plugin to the browser plugin directory.
4. Restart Firefox v52 ESR to connect to APM.

Fix:
This issue has been fixed, and now you can install the Network Access plugin on Linux Ubuntu 16.04 with Firefox v52 ESR browser.

718071-3 : HTTP2 with ASM policy not passing traffic

Component: Local Traffic Manager

Symptoms:
HTTP2 traffic does not pass traffic if an ASM policy is applied.

Conditions:
-- HTTP2 virtual server.
-- ASM policy applied.

Impact:
Traffic does not pass.

Workaround:
No workaround.

Fix:
HTTP2 and ASM now work correctly together.

717896-1 : Monitor instances deleted in peer unit after sync

Component: Local Traffic Manager

Symptoms:
An incremental-sync from a modified-node that was set to 'user-down' causes the target-node on the target-device to have only a single monitor instance, rather than the several monitor instances that were present on the from-node.

During the incremental sync, the system issues several messages similar to the following: err mcpd[6900]: 01070712:3: Caught configuration exception (0), Invalid monitor rule instance identifier: 24913.

Conditions:
-- In high availability (HA) configurations.
-- A node is modified, and then manually set to 'user-down'.
-- That node has more than one associated monitor.
-- An incremental-sync occurs to the paired device.

Impact:
After incremental-sync, a single monitor instance exists for the node on a 'backup' unit in an HA configuration, rather than the several monitor instances that exist for that node on the 'active' unit; and that node session is 'enabled' (where the 'from-node' was 'disabled); and that node status may be 'up' (where the 'from-node' was 'user-down'), and later transition to 'down' from a monitor-fail.

Thus, after incremental-sync, the target-node may then be 'down', while the active unit in the HA configuration continues to function as expected.

Workaround:
There are several workarounds:
-- Perform a 'full-sync' (rather than an 'incremental-sync').
-- Ensure the node is 'user-up' (not 'user-down') before the incremental-sync.
-- Perform 'tmsh load sys config' on the target unit. In this case, the 'Invalid monitor rule instance identifier' messages will be seen, but the configuration will successfully load, and the target-unit will run correctly with the expected configuration.

Fix:
An incremental-sync from a modified-node that was set to 'user-down' successfully replicates the several monitor instances on that node to the target-node on the backup device in an HA configuration.

717742-3 : Oracle Java SE vulnerability CVE-2018-2783

Solution Article: K44923228

717100-4 : FQDN pool member is not added if FQDN resolves to same IP address as another existing FQDN pool member

Component: Local Traffic Manager

Symptoms:
FQDN ephemeral pool members and corresponding FQDN ephemeral nodes may not be created if multiple FQDN template pool members are created rapidly, without the corresponding FQDN template nodes being created first.

The missing FQDN ephemeral pool members may be created an hour after initial operations.

Conditions:
This may occur when all of the following conditions are true:
-- Multiple FQDN template pool members are created rapidly, such as during config load or multiple FQDN template pool members created in a single tmsh cli transaction, without the corresponding FQDN template nodes being created first.
-- The FQDN names in the newly-created FQDN template nodes all resolve to the same IP address.

Impact:
One or more FQDN ephemeral pool members may not be created, which could result in a pool with no members, and any virtual servers using that pool to fail to pass traffic.

Workaround:
The following steps, alone or in combination, may help avoid this issue:

1. Avoid rapid creation of multiple FQDN template pool members (such as by creating multiple in a single tmsh CLI transaction).
2. Create the corresponding FQDN template nodes first, before creating the FQDN template pool members.

Once this issue occurs (such as, after a config load), you can recover from this condition by deleting and recreating the FQDN template pool members that have no corresponding FQDN ephemeral pool members.

In addition, creating the corresponding FQDN template nodes first, with an FQDN 'interval' value set to a shorter timeout than the default (3600 seconds) allows automatic recovery from this condition after the configured FQDN 'interval' period (instead of after the default period of one hour).

Fix:
Ephemeral pool members are now created for each pool under these conditions.

716992-3 : The ASM bd process may crash

Solution Article: K75432956

716922-4 : Reduction in PUSH flags when Nagle Enabled

Component: Local Traffic Manager

Symptoms:
When Nagle is enabled in the TCP profile, the number of PUSH flags generated by the BIG-IP system drops substantially compared to the Nagle-disabled case, or to the Nagle-enabled case prior to v12.1.2-HF1. This matters most when there is a single outstanding unsent segment in the send buffer awaiting acknowledgment of all other data.

Conditions:
-- Nagle is enabled.
-- Running BIG-IP software versions later than v12.1.2-HF1.

Note: The problem is only impactful when the client withholds ACKs when there is no PUSH flag.

Impact:
If the client withholds ACKs, this can save handset power, but it also causes Nagle's algorithm to withhold the last bit of data, increasing latency.

Workaround:
Set Nagle to the 'Auto' setting or 'Disabled'.

Mote: To take advantage of some of the Nagle benefits, use 'Auto'.

Fix:
Revised PUSH flag setting logic to set the flag in cases where sending is Nagle-limited.

716900-1 : TMM core when using MPTCP

Solution Article: K91026261

716788-3 : TMM may crash while response modifications are being performed within DoSL7 filter

Component: Application Security Manager

Symptoms:
TMM might crash when a response is modified by the DoSL7 filter while injecting an HTML response from a backend server.

Conditions:
-- ASM provisioned.
-- DoS application profile is attached to a virtual server.

Impact:
Traffic disrupted while tmm restarts, failover may occur.

Workaround:
There is no workaround other than to remove the DoS application profile from the virtual server.

Fix:
Response modification handler has been modified so that this issue no longer occurs.

716747-4 : TMM my crash while processing APM or SWG traffic

Component: Access Policy Manager

Symptoms:
Under certain circumstances, TMM may crash when processing APM or SWG.

There will be a log message in /var/log/apm near the time of crash with this:

err tmm[20598]: 01490514:3: (null):Common:00000000: Access encountered error: ERR_ARG. File: ../modules/hudfilter/access/access.c, Function: access_initiate_swgt_policy_done, Line: 17000.

Conditions:
APM or SWG enabled.

Impact:
TMM crash, leading to a failover event.

Workaround:
There is no workaround at this time.

Fix:
TMM now processes APM and SWG traffic as expected.

716716-3 : Under certain circumstances, having a kernel route but no TMM route can lead to a TMM core

Component: Local Traffic Manager

Symptoms:
TMM cores when the system has a kernel route configured, but no matching TMM route.

Conditions:
The scenario that can lead to this state is unknown.

Impact:
TMM cores. Traffic disrupted while tmm restarts.

Workaround:
Either remove the kernel route, or add a matching TMM route.

Fix:
This release prevents the core that occurred when the kernel has a route that has no corresponding TMM route.

716391-3 : High priority for MySQL on 2 core vCMP may lead to control plane process starvation

Solution Article: K76031538

Component: TMOS

Symptoms:
vCMP guest with only 2 cores (or 2 cores per blade for multi-blade guests) may undergo control plane process starvation, which could lead to failover due to CPU starvation of sod.

Conditions:
-- A device using Intel Hyper-Threading Technology is configured with only 2 cores (or 2 cores per blade for multi-blade vCMP guests).
-- A module using MySQL is provisioned, MySQL, for example BIG-IP ASM and BIG-IP Analytics (AVR). These other modules also implicitly provision AVR: ASM, AFM, DOS, APM, PEM, and vCMP.

Impact:
Control plane processes may experience CPU starvation, including failover due to CPU starvation of sod. This is a rarely occurring issue.

Workaround:
Revert to pre-11.5.1 HF4 behavior by setting the scheduler.splitplanes.asmopt database key to false.

IMPORTANT: You should not revert to pre-11.5.1 HF4 behavior unless requested by F5 Support. However, if required, you can disable this new behavior and revert to pre-11.5.1-HF4 behavior. For instructions on how to do so, see K16469: Certain BIG-IP ASM control plane processes are now pinned to the highest-numbered logical CPU core :: https://support.f5.com/csp/article/K16469.

716318-4 : Engine/Signatures automatic update check may fail to find/download the latest update

Component: Fraud Protection Services

Symptoms:
Engine/Signatures automatic update check may fail to find/download the latest update if the timestamp of the factory update file is later than the timestamp of the update file in downloads.f5.com.

Note: This issue is relevant only for engineering hotfixes.

Conditions:
This occurs when the following conditions are met:
-- Engineering hotfix.
-- The factory update file timestamp is later than the timestamp of the update file in downloads.f5.com.

Impact:
Automatic update check will detect the wrong update file.

Workaround:
Manually check, and then download and install the update file from downloads.f5.com, if needed.

Fix:
The factory update file timestamp is now set to 0, unless there is a reason to install the factory file over the current update file in downloads.f5.com.

716213-3 : BIG-IP system issues TCP-Reset with error 'SSID error (Out of Bounds)' in traffic

Component: Local Traffic Manager

Symptoms:
When APM connects to Active Directory Federation Services (ADFS), a blank page is observed. The log file /var/log/ltm exhibits a TCP reset issued by the BIG-IP system. The TCP capture informs that the issue is due to an out-of-bounds error that occurs when traffic gets parsed by the SSL Persistence Parser (SSID).

Conditions:
-- SSL persistence (SSID) is enabled for a virtual host.
-- APM connects to ADFS.

Impact:
A blank page is observed due to the TCP reset.

Workaround:
No workaround is available.

Fix:
The SSL persistence parser now validates the handshake message data-bytes are available prior to fetching them, so the bounds error does not get raised.

716166-3 : Dynamic routing not added when conflicting self IPs exist

Component: TMOS

Symptoms:
Missing dynamic route in dynamic routing daemon as shown via 'show ip route'.

Conditions:
When a self IP host address is the same as the network address of the dynamic route being propagated. For example: self IP 10.10.10.0/31 versus dynamic route 10.10.10.0/24; or 10.10.0.0/24 versus dynamic route 10.10.0.0/16.

Impact:
Propagation of the dynamic route to the kernel, TMM.

Workaround:
There is no workaround other than not creating self IPs on the network address of a prefix.

715923-3 : When processing TLS traffic TMM may terminate connections unexpectedly

Solution Article: K43625118

715750-3 : The BIG-IP system may exhibit undesirable behaviors when receiving a FIN midstream an SSL connection.

Component: Local Traffic Manager

Symptoms:
Upon receiving a FIN midstream in an SSL connection, the BIG-IP system will immediately proxy the FIN to the remote host on the peer side. At this point, depending on the specific configuration of the remote host on the peer side, the BIG-IP system may exhibit behaviors that may be deemed undesirable.

For instance, if the remote host on the peer side acknowledges the FIN but ignores it and keeps sending data to the BIG-IP system, the BIG-IP system will drop all ingress data (i.e., not proxy it) while keeping the side that transmitted the original FIN open indefinitely.

Once the remote host on the peer side completes transmitting data and sends a FIN of its own, the BIG-IP system will finally release the side that sent the original FIN by allowing it to close.

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

-- A standard virtual server with the clientssl and serverssl profiles in use.

-- As part of a connection handled by the virtual server, one side sends a FIN midstream to the BIG-IP system.

Impact:
There is no real impact to the BIG-IP system because of this issue. However, both the client and the server can be negatively impacted by this issue.

For example, if the original FIN was received by the BIG-IP system on the clientside:

-- The client connection is not allowed to close for potentially a very long time. During this time, the client does not receive anything other than Keep-Alive packets from the BIG-IP system. This can delay or adversely impact applications on the client.

-- The server continues to send data to the BIG-IP system unnecessarily. After accounting for the fact this could be a lot of data and many connections could be in this state, the server and/or its surrounding network could become impacted/congested. At a minimum, this might cause a waste of resources.

Workaround:
There is no workaround at this time.

Fix:
SSL shutdown behavior is controlled with profile option 'Alert Timeout', which specifies the duration in time for the system to try to close an SSL connection before resetting the connection. The default is 'Indefinite'.

Behavior Change:
SSL shutdown behavior is controlled with profile option 'Alert Timeout', which specifies the duration in time for the system to try to close an SSL connection before resetting the connection. The default is 'Indefinite'.

715467-3 : Ephemeral pool member and node are not updated on 'A' record changes if pool member port is ANY

Component: Local Traffic Manager

Symptoms:
If the 'A' record for an FQDN node is removed or replaced on the DNS server, then the BIG-IP system does not remove the old ephemeral pool member or create the new pool member and node.

Conditions:
-- FQDN nodes.
-- Pool members with a service port of ANY.

Impact:
Ephemeral pool member and nodes are not removed or updated when the DNS 'A' record is removed or changed.

Workaround:
There is no workaround at this time.

Fix:
Upon a DNS 'A' record being removed or changed, the ephemeral pool members and nodes based on the old value are removed or changed.

715448-1 : Providing LB::status with a GTM Pool name in a variable caused validation issues

Component: Global Traffic Manager (DNS)

Symptoms:
When utilizing an LB::status iRule where the GTM Pool name was provided in a variable, instead of directly written into the command, the system posts the following error message: Can't read 'monkey': no such variable.

Conditions:
LB::status pool a <Variable containing string>.

Impact:
Unable to use LB::status iRule.

Workaround:
There is no workaround at this time.

Fix:
Can now use LB::status iRule command to display the status of a GTM Pool when the name of the pool is provided in a variable.

715250-2 : TMM crash when RPC resumes TCL event ACCESS_SESSION_CLOSED

Component: Access Policy Manager

Impact:
System instability, failover, traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

715207-2 : coapi errors while modifying per-request policy in VPE

Component: Access Policy Manager

Symptoms:
System reports errors about coapi in /var/log/ltm when modifying a per-request policy in the Visual Policy Editor (VPE).

err coapi: PHP: requested conversion of uninitialized member.

Conditions:
-- The per-request policy being modified is attached to the virtual server.
-- Using VPE.

Impact:
The impact can vary by version.
-- In some versions it represents a stray error log.
-- In other versions the 'Accepted Languages' in the Logon Page agent does not have the full list.
-- In other versions, there are server 500 errors when modifying agents.

Workaround:
To work around this issue, perform the following procedure: 1. Remove the per-request policy from the virtual server.
2. Modify the policy.
3. Add the policy back to the virtual server.

Fix:
Now per-request access policies can be simultaneously used and edited without causing spurious 'coapi' log errors.

715090 : PEM policy actions obtained via a PCRF are not applied for traffic generated subscribers

Component: Policy Enforcement Manager

Symptoms:
Policy and Charging Rules Function (PCRF) policy actions will have no effect on the subscribers' traffic.

Conditions:
PEM creates a traffic generated subscriber that has PCRF-provided policies associated with it.

Impact:
Potential loss of service depending on the policy actions that do not take effect.

Workaround:
There is no workaround at this time.

Fix:
This issue has been fixed.

714986-1 : Serial Console Baud Rate Loses Modified Values with New Logins on iSeries Platforms Without Reboot

Component: TMOS

Symptoms:
On an iSeries platform, when the console baud rate is changed through TMSH, new terminal sessions revert back to the previous baud rate instead of adopting the new setting unless the unit is rebooted.

Conditions:
1. Modify the console baud rate in BIG-IP through TMSH on an iSeries platform (i2xxx, i4xxx, i5xxx, i7xxx, i10xxx, i15xxx), for example: tmsh modify sys console baud-rate 9600.

2. Exit from the login prompt in the current terminal session, or kill it and start a new session.

Impact:
The BIG-IP system reverts to the previous baud rate instead of the new setting. Inability to create any new serial console connections with the modified baud-rate without a reboot.

Workaround:
The problem can be mitigated by manually reprogramming the TTY device and restarting the agetty process and bash login sessions. This closes any existing console connections, but newly established connections will connect at the modified baud rate.

1. Use TMSH to modify the baud rate to the desired speed by running a command similar to the following:

tmsh modify sys console baud-rate 9600

2. Re-program the TTY device with the desired speed by running a command similar to the following:

stty -F /dev/ttyS0 9600

3. Kill the existing agetty process so it will re-start at the new baud rate by running the following command:

/usr/bin/killall -q agetty

4. Restart bash logins by running the following command:

/bin/kill -HUP `/bin/ps -A | /bin/grep ttyS0 | /bin/grep -v grep | /bin/grep bash | /bin/awk '{print $1}'` >/dev/null 2>&1

Fix:
In addition to reprogramming the UART with the new baud rate, the BIG-IP system now re-initializes the TTY device and agetty process with the correct speed so that new terminal sessions reflect the change.

A single warning message is expected, not repeating messages.

Conditions:
This occurs when all of the following conditions are met:
-- The interface is disabled.
-- DDM is enabled.
-- OPT-0031 or OPT-0036.

Impact:
There are multiple messages in /var/log/ltm, and SNMP DDM traps. There is no impact on traffic.

Workaround:
There is no workaround other than to enable the interface or disable DDM.

Fix:
DDM errors no longer continually appear on disabled interfaces containing OPT-0031 or OPT-0036.

Symptoms:
While creating a static route, tmrouted disconnects with error: existing entry is not a dynamic.

Conditions:
Creating a static route for a network that already has an advertised dynamic route.

Impact:
TMM's connection to tmrouted goes down, which results in loss of the dynamic route for TMM.

Workaround:
There is no workaround other than not creating a static route for routes received through dynamic routing.

Fix:
Creating static routes for advertised dynamic route no longer causes the tmrouted-to-TMM connection to drop.

714559-1 : Removal of HTTP hash persistence cookie when a pool member goes down.

Component: Local Traffic Manager

Symptoms:
When HTTP cookie hash persistence is configured the cookie is removed when a pool member goes down. This is incorrect if pool members are using session replication.

Conditions:
- Cookie hash persistence is configured.
- A pool member that the persistence record points to goes down.
- Pool members are using session replication.

Impact:
Connected clients must establish a new session.

Workaround:
To configure HTTP cookie hash persistence, use an iRule similar to the following:

when CLIENT_ACCEPTED {
persist cookie hash JSESSIONID
}

712464-1 : Exclude the trusted anchor certificate in hash algorithm selection when Forward Proxy forges a certificate

Component: Local Traffic Manager

Symptoms:
SSL Forward Proxy signs a forged certificate with a hash algorithm. This selected hash algorithm is the weakest algorithm from the certificates in the server certificate chain except the self-signed certificate.

Some of the intermediate CA certificates in the cert chain use the SHA1 hash algorithm. This kind of intermediate CAs is usually in the BIG-IP system's ca-bundle. BIG-IP receives the cert chain including the intermediate CA and forges the cert with SHA1, which is rejected by some web clients.

Conditions:
-- The BIG-IP system is configured to use SSL Forward Proxy or SSL Intercept.
-- Some intermediate CA in the web server's cert chain is using a weak algorithm like SHA1 to sign certificates.
-- The web client rejects the weak-algorithm-signed certificate.

Impact:
Clients cannot access the web server due to SSL handshake failure.

Workaround:
There is no workaround at this time.

Fix:
This fix excludes trusted CA certificates in hash algorithm selection. This may prevent forged certificate from using SHA1 hash algorithm.

712437-1 : Records containing hyphens (-) will prevent child zone from loading correctly

Solution Article: K20355559

Component: Local Traffic Manager

Symptoms:
The dig command returns no record with SOA from the parent zone even though dnsxdump shows that the record exists.

Conditions:
-- Parent zone has a record containing - (a hyphen) and the preceding characters match the child zone. For example,
myzone.com -- parent
foo.myzone.com -- child

-- In myzone.com, you have a record of the following form:
foo-record.myzone.com

Impact:
DNS can not resolve records correctly.

Workaround:
None.

Fix:
DNS now handles the case in which the parent zone has a record containing - (a hyphen) and the preceding characters match the child zone.

712362-1 : ASM stalls WebSocket frames after legitimate websockets handshake with 101 status code, but without 'Switching Protocols' reason phrase

Component: Application Security Manager

Symptoms:
When the WebSocket HTTP handshake response comes without 'Switching Protocols' reason phrase at the first line, the ASM does not follow up WebSocket frames on the WebSocket's connection.

The system posts the following messages in /ts/log/bd.log:
-- IO_PLUGIN|ERR |Mar 28 09:16:15.121|30539|websocket.c:0269|101 Switching Protocols HTTP status arrived, but the websocket hanshake failed.
-- IO_PLUGIN|ERR |Mar 28 09:16:15.121|30539|websocket.c:0270|Possible reasons are websocket profile isn't assigned on a virtual server or handshake is illegal.

Conditions:
-- ASM provisioned.
-- ASM policy and WebSocket profile attached to a virtual server.
-- WebSocket backend server sends 101 response without the 'Switching Protocols' phrase.

Impact:
WebSocket frames stalls.

Workaround:
#1 Change the backend server:
Change WebSocket backend server to return 101 response to include the 'Switching Protocols' reason phrase:

HTTP/1.1 101 Switching Protocols

#2 Use an irRule:
when SERVER_CONNECTED {
    TCP::collect 15
}
when SERVER_DATA {
    if { [TCP::payload 15] contains "HTTP/1.1 101 \r\n" } {
        TCP::payload replace 0 12 "HTTP/1.1 101 Switching Protocols"
    }
}

Fix:
This release correctly handles 101 responses even without the 'Switching Protocols' reason phrase.

Conditions:
A valid PMTU message.

Impact:
BIG-IP sends larger-than-configured interface egress MTU messages.

Workaround:
None.

Fix:
The BIG-IP system now limits the flow egress MTU to the interface egress MTU.

711281-3 : nitrox_diag may run out of space on /shared

Component: Local Traffic Manager

Symptoms:
Running nitrox_diag may lose collected data if there is insufficient free space for the tar file to be created.

Conditions:
-- Running nitrox_diag.
-- Insufficient free space available on /shared.

Impact:
Might lose data required to diagnose problems with Cavium Nitrox chips.

Workaround:
The only workaround is to ensure there is enough free space for the files to be created.

In general, planning enough space for two copies of a tmm core file and two copies of a qkview works. That might require approximately one gigabyte. Though more might be needed for systems with a large amount of RAM.

Fix:
nitrox_diag now clears the older data before gathering new data, instead of after. Note, however, that if there is insufficient free space on /shared to collect the raw data, the operation still cannot succeed.

Conditions:
-- ASM provisioned.
-- ASM policy attached to a virtual server.
-- ASM remote logger attached to a virtual server.
-- Request including binary NULL character is sent to the remote logger destination.

Impact:
Partial request is logged at the remote logger destination.

Workaround:
None.

Fix:
Binary NULL character is now escaped before being sent to the remote logger destination, so the request is no longer truncated.

710028-4 : LTM SQL monitors may stop monitoring if multiple monitors querying same database

Component: Local Traffic Manager

Symptoms:
When using an SQL monitor to monitor the health of SQL database pool members, one of the health monitors may stop actively monitoring one or more pool members.

When this problem occurs, the following error messages may be logged in /var/log/DBDaemon-0.log:

[if debug = yes in monitor configuration]:
Using cached DB connection for connection string '<connection string>'

then multiple, periodic instances of the following message, referencing the same connection string:

Abandoning hung SQL query: '<query string>' for: '<connection string>'

or:

<connection string>(<thread-number>): Hung SQL query; abandoning

Conditions:
This may occur when all of the following conditions are met:
-- Using one of the following LTM monitors: mssql, mysql, oracle, postgresql.
-- Configuring multiple pool members for the same node (server).
-- Configuring multiple SQL monitors that query the same server and database.

And when one or both of the following conditions are met:
Either:
-- The SQL monitor is configured with a non-zero 'count' value.
Or:
-- An error occurs while querying a SQL database, such as [recorded in the DBDaemon log]:
java.io.EOFException: Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.

Impact:
When this problem occurs, the affected pool members are reported down, even though the database is actually up and responding correctly to traffic.

Workaround:
When this problem occurs, successful monitoring can be temporarily restored by disabling then re-enabling monitoring of affected pool members.

To avoid one possible trigger for this issue (and thus reduce the likelihood of this issue occurring), configure the 'count' parameter in the SQL monitor configuration to a value of '0'.

Fix:
LTM SQL monitors continue monitoring when multiple monitors/ query the same server and database.

709688-5 : dhcp Security Advisory - CVE-2017-3144, CVE-2018-5732, CVE-2018-5733

Solution Article: K08306700

709670-5 : iRule triggered from RADIUS occasionally fails to create subscribers.

Component: Policy Enforcement Manager

Symptoms:
The subscriber can not be added with the same IP address after retries. This is a rarely occurring issue: if the daily average of subscriber additions is ~30000 subscribers, 5 to 6 subscribers face this problem (0.02%).

Conditions:
Running iRule to create PEM sessions from RADIUS packets using the 'PEM::subscriber create' command.

Impact:
Intermittently (a few operations per day), the command silently fails. No session is created, and no TCL error is produced. Subscriber addition requires manual intervention.

Workaround:
Trigger a RADIUS START using a different IP address for the subscriber.

709610-1 : Subscriber session creation via PEM may fail due to a RADIUS-message-triggered race condition in PEM

Component: Policy Enforcement Manager

Symptoms:
Session replacement fails as a result of a race condition between multiple RADIUS Accounting Start and Stop messages for the same subscriber.

Conditions:
This occurs when the following conditions are met:
-- These SysDB variables are set as follows:
sys db tmm.pem.session.radius.retransmit.timeout {
value "0"
}
sys db tmm.pem.session.provisioning.continuous {
value "disable"
}

-- Actions occur in the following order:
1. PEM receives RADIUS START with subscriber ID1 and IP1.
2. PEM receives RADIUS STOP with subscriber ID1 and IP1.
3. PEM receives RADIUS START with subscriber ID1 and IP2.
4. PEM receives RADIUS STOP with subscriber ID1 and IP2.

-- The time interval between steps 1 and 2 is very small (less than ~1ms).

Impact:
Subscriber session creation via PEM may fail.

Workaround:
There is no workaround other than to leave SysDbs variables set to the default values.

Fix:
The system now handles PEM subscriber session updates properly, so this issue no longer occurs.

709544-4 : VCMP guests in HA configuration become Active/Active during upgrade★

Component: TMOS

Symptoms:
When devices in a Device Service Cluster (DSC) are upgraded, multiple devices might become Active simultaneously.

During upgrade, the process erroneously clears the management-ip during reboot, and then synchronizes to other members of the DSC. If the system is not performing an upgrade, the error is repaired as the device starts up, and has no visible effect. If an upgrade is being performed, the management-ip cannot be repaired, and the DSC members lose contact with each other, so they all become Active.

Conditions:
-- Running on VIPRION chassis systems, either natively, or as a vCMP guest.
-- Upgrading from any affected versions (TMOS v12.1.3, TMOS v13.0.0, TMOS v13.0.1, TMOS v13.1.0), to any other version.

Impact:
When multiple devices become Active simultaneously, traffic is disrupted.

Workaround:
There is no workaround other than to remain in Active/Active state until upgrade is complete on all chassis in the DSC are finished. See K43990943: VIPRION systems configured for high availability may become active-active during the upgrade process :: https://support.f5.com/csp/article/K43990943 for more information on how to mitigate this issue.

Fix:
The erroneous management-ip change is not made, and the HA failover mechanism operates correctly across upgrade.

709334-2 : Memory leak when SSL Forward proxy is used and ssl re-negotiates

Component: Local Traffic Manager

Symptoms:
When looking at tmsh show sys memory you will see
ssl_compat continue to grow and fails to release memory.

Conditions:
-SSL Forward Proxy In use
-SSL Re-negotiations happening

Impact:
Eventually memory reaper will kick in.

Workaround:
There is no workaround at this time.

Fix:
ssl_compat now properly releases connections on re-negotiation.

708956 : During system boot, error message displays: 'Dataplane INOPERABLE - only 1 HSBes found on this platform'

Solution Article: K51206433

Component: TMOS

Symptoms:
During system bootup, the system occasionally posts the following error message and the system does not come up:
Dataplane INOPERABLE - only 1 HSBes found on this platform.

Conditions:
This occurs occasionally at system bootup.
-- Using the following platforms:
i4600, i4800, i10600, i10800, i2600, i2800, i7600, i7800, i5600, i5800, i15600, i15800, i12600, i12800, HERCULON i2800, HERCULON i5800, HERCULON i10800, i11600, i11800, i11800-DS, i5820-DF, i7820-DF.

Impact:
System does not come up.

Workaround:
Reboot system.

Because this condition only happens occasionally, rebooting typically corrects the issue.

Fix:
This release fixes a race condition that might have occurred while reading FPGA firmware loading status.

708830-1 : Inbound or hairpin connections may get stuck consuming memory.

Component: Carrier-Grade NAT

Symptoms:
When inbound or hairpin connections require a remote Session DB lookup, and the lookup request or response messages get lost, the connections can get stuck in an embryonic state. They remain stuck in this state until they time out and expire. In this state, UDP connections queue inbound packets. If the client application continues to send packets, the connection may never expire. The queued packets accumulate, consuming memory. If the memory consumption becomes excessive, connections may be killed and 'TCP: Memory pressure activated' and 'Aggressive mode activated' messages appear in the logs.

Conditions:
-- An LSN pool with inbound and/or hairpin connections enabled.
-- Lost Session DB messages due to heavy load or hardware failure.
-- Remote lookups are more likely when using PBA mode or NAPT mode with default DAG.

Impact:
Excessive memory consumption that leads to dropped connections.

Workaround:
There is no workaround at this time.

Fix:
When Session DB messages are lost, the connection is killed and any queued packets are discarded. If the client application resends packets, they are treated as new connections.

708653-3 : TMM may crash while processing TCP traffic

Solution Article: K07550539

708249-4 : nitrox_diag utility generates QKView files with 5 MB maximum file size limit

Component: Local Traffic Manager

Symptoms:
When nitrox_diag generates a QKView file, the utility does not use the -s0 flag for the qkview command. That means there is a 5 MB file-size limit for the resulting QKView file nitrox_diag generates.

Conditions:
Run the nitrox_diag command.

Impact:
QKView files generated in response to running the nitrox_diag command might not contain all necessary information, for example, the result might contain truncated log files.

Workaround:
After running nitrox_diag, run the following command to generate a complete QKView file: qkview -s0

Fix:
Nitrox_diag utility now uses the -s0 command to generate QKView files, so there is no longer a 5 MB maximum file size limit, and the full QKView file is created.

708114-3 : TMM may crash when processing the handshake message relating to OCSP, after the SSL connection is closed

Solution Article: K33319853

Component: Local Traffic Manager

Symptoms:
TMM crashes when receiving the HUDEVT_SSL_OCSP_RESUME_CLNT_HS after the SSL connection is closed.

Conditions:
-- The SSL connection has been closed.
-- SSL receives the HUDEVT_SSL_OCSP_RESUME_CLNT_HS message.

Impact:
TMM crash. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
The system now ensures that SSL can still properly process the messages, even when the SSL connection is closed.

708068-3 : Tcl commands like "HTTP::path -normalize" do not return normalized path.

Component: Local Traffic Manager

Symptoms:
When using HTTP::path with the -normalized parameter:

"%2E%2E" is converted to ".." (expected)
"/foo/../bar" is converted to "/bar" (expected)
"/foo/%2E%2E/bar" is converted to "/foo/../bar" (unexpected)

Conditions:
The TCL command HTTP::path -normalize does not return normalized path as expected.

Impact:
Unexpected result.

Workaround:
There is no workaround.

Fix:
The TCL command HTTP::path -normalize should return normalized path.

708054-3 : Web Acceleration: TMM may crash on very large HTML files with conditional comments

Component: TMOS

Symptoms:
Web Acceleration feature may not handle big HTML file with improper conditional comments inside in some cases. TMM may crash processing such files if Web Acceleration profile is attached to VIP.

Conditions:
- HTML file with conditional comments inside:


- The size of "condition" from the pattern above is comparable with RAM size of BIG-IP box, i.e. ~8-10GB.

Impact:
TMM crash interrupts all active sessions.

Workaround:
There is no workaround at this time.

Fix:
Now Web Acceleration feature can handle long HTML conditional comments correctly.

707888 : Some ASM operations delayed due to scheduled ASU update

Component: Application Security Manager

Symptoms:
Some ASM operations (such as Apply Policy) are delayed while a scheduled ASU update is in progress. This issue affects only 12.1.3.x from 12.1.3.2 and later.

Conditions:
A scheduled ASM update is in progress on systems running v12.1.3.x.

Impact:
Some ASM operations, such as Apply Policy, are delayed.

Workaround:
There is no workaround at this time.

Fix:
Other ASM operations are no longer blocked by scheduled ASU update.

707740-3 : Failure deleting GTM Monitors when used on multiple virtual servers with the same ip:port combination

Component: TMOS

Symptoms:
When attempting to delete a GTM monitor, the system indicates that it is in use, even after removing that monitor from all GTM virtual servers. The system posts a message similar to the following:
01070083:3: Monitor /Common/mon-A is in use.

Conditions:
1. Attach a GTM monitor to multiple GTM virtual servers in the same transaction, where both of the virtual servers are monitoring the same ip:port.
2. Remove the monitor from all virtual servers.
3. Attempt to delete the monitor from the configuration.

Impact:
Cannot delete the unused monitor.

Workaround:
After removing the monitor from all virtual servers, reload the GTM configuration using the following command:
tmsh load sys config gtm-only

You can now delete the monitor.

Fix:
You can now delete an unused GTM monitor, if that monitor was attached to multiple GTM virtual servers of the same ip+port combination.

707675 : FQDN nodes or pool members flap when DNS response received

Component: Local Traffic Manager

Symptoms:
When an LTM pool is configured with FQDN nodes or pool members, the LTM pool and associated virtual server(s) may transition from an UP to DOWN state and back over a period of a few seconds.

Such an event is accompanied by log messages similar to the following:

-- notice mcpd[#]: 01071682:5: SNMP_TRAP: Virtual /Common/vs_test has become unavailable
-- notice mcpd[#]: 010719e7:5: Virtual Address /Common/123.45.67.89 general status changed from GREEN to RED.
-- notice mcpd[#]: 010719e8:5: Virtual Address /Common/123.45.67.89 monitor status changed from UP to DOWN.
-- err mcpd[#]: 01020066:3: The requested Pool Member (/Common/Test_Pool /Common/test-dummy.com-12.34.56.78 443) already exists in partition Common.
-- notice bigd[##]: 01060144:5: Pool /Common/Test_Pool member /Common/test-dummy.com-12.34.56.78 session status enabled by monitor
-- notice bigd[##]: 01060145:5: Pool /Common/Test_Pool member /Common/test-dummy.com-12.34.56.78 monitor status up. [ /Common/mon_test_https: UP ] [ was checking for 0hr:0min:2sec ]
-- notice mcpd[#]: 01071681:5: SNMP_TRAP: Virtual /Common/vs_test has become available
-- notice mcpd[#]: 010719e7:5: Virtual Address /Common/123.45.67.89 general status changed from RED to GREEN.
-- notice mcpd[#]: 010719e8:5: Virtual Address /Common/123.45.67.89 monitor status changed from DOWN to UP.

This symptom repeats each time a DNS query is performed to resolve the FQDN node/pool-member name to its IP addresses, based on the 'interval' value configured for the FQDN node.

This symptom occurs only when the 'autopopulate' value is set to 'enabled' for the FQDN node/pool-member.

Conditions:
-- LTM pool is configured with FQDN nodes or pool members.
-- The 'autopopulate' value is set to 'enabled' for the FQDN node/pool-member.

Impact:
LTM pool and virtual server are briefly and periodically marked DOWN. Traffic may be impacted.

Workaround:
Either of the following methods can be used to work around this issue:

-- Configure static IP addresses instead of FQDN nodes/pool-members.

-- Set the 'autopopulate' value to 'disabled' for the FQDN node/pool-member, if possible (that is, if only one IP address is required/expected to be returned for the FQDN name, which means that the 'autopopulate' feature of FQDN nodes/pool-members is not required).

Fix:
FQDN node/pool-member and corresponding pool and virtual server are no longer briefly marked DOWN when the DNS server is queried to resolve the FQDN name, with the 'autopopulate' feature enabled for the FQDN node/pool-member. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

707509-3 : Initial vCMP guest creations can fail if certain hotfixes are used

Component: TMOS

Symptoms:
vCMP guest fails to enter the 'provisioned' or 'deployed' states and similar messages can be seen in /var/log/ltm:

-- vcmpd[14254]: 01510003:2: Guest (guest_name): Install failed.
-- vcmpd[14254]: 01510004:3: Guest (guest_name): Install to VDisk /shared/vmdisks/guest_name.img FAILED: Child exited with non-zero exit code: 255

Conditions:
Creating vCMP guest using certain hotfix images, such as BIG-IP HF software released as partial .iso software images, and engineering hotfixes.

Impact:
vCMP guest cannot be created.

Workaround:
1. Create and deploy the vCMP guest using the full .iso base software image.
2. Log in to the vCMP guest once it has finished starting up.
3. Apply the hotfix image or engineering hotfix.

Fix:
Guest creation succeeds.

707447-2 : Default SNI clientssl profile's sni_certsn_hash can be freed while in use by other profiles.

Component: Local Traffic Manager

Symptoms:
SSL SNI mechanism creates a hash containing a mapping between SAN entries in a given profile's certificate and the profile. This hash is owned by the default SNI profile, however is held by the other profiles on the VIP without a reference. If a connection utilizes SNI to use a non-default SNI profile *and* the default SNI profile reinitializes its state for any reason, the prf->sni_certsn_hash can be cleared and freed, leaving the existing connection(s) with profiles that refer to the freed hash. If then the connection attempts a renegotiation that causes the hash to be used, the freed hash can cause a fault should it have been reused in the meantime (i.e. the contents are invalid).

The fix: When the default SNI profile is initializing, and SSL handshake is searching SAN/COMMON cert from
non-default SNI profile, stop the search and return NULL.

Conditions:
SNI configured with one default SNI profile, one or multiple SNI profiles. The default SNI profile is changed and renegotiation with SNI(with non-default SNI profile) is issued.

Impact:
Traffic is disrupted while TMM restarts.

Workaround:
There is no workaround at this time.

Fix:
When the default SNI profile is initializing, and SSL handshake is searching SAN/COMMON cert from non-default SNI profile, stop the search and return NULL.

707445 : Nitrox 3 compression hangs/unable to recover

Solution Article: K47025244

Component: TMOS

Symptoms:
LTM logs show the following message:

Nitrox 3, Hang Detected: compression device was reset

When the error manifests, there will be three error messages sent to the log over a period of several seconds. The device is then considered unrecoverable and marked down, and will no longer accept compression requests.

Conditions:
This applies only to vCMP guests. Some compression requests can stall the device after a bad compression request is made.

Note: Traffic volume and concurrence, along with the type of error have to occur together in order to result in this issue, so the issue is not easily reproduced.

Impact:
Once the device is marked down, compression will be sent to the software compression provider, until tmm on the device is restarted. This can cause local CPU utilization to climb.

Workaround:
There is no complete workaround without a software fix. However, compression will always default to the software compression provider when hardware cannot be recovered.

There are three recovery options available if the TMM-internal reset fails to recover the compression device automatically. These should be employed in this order:

A. Restart tmm using the command: bigstart restart tmm.
B. Restart the vCMP guest.
C. Restart the host (which restarts all guests).

Note: Because of the traffic volume, timing, and error type that cause this condition, this error might recur. This issue appears to be caused by a particular compression request. So regardless of the recovery method you execute, the problem may recur in a short time, or months later.

Fix:
Compression device reset recovery made more robust for some compression failures.

707391-4 : BGP may keep announcing routes after disabling route health injection

Component: TMOS

Symptoms:
As a result of a known issue BIG-IP with BGP configured may continue to announce routes even after disabling the virtual address or disabling route announcement on the virtual address.

Conditions:
BGP configured with multiple routes announced via Virtual-address route announcements.
Configuration changes made on the BGP configuration itself.
Virtual address or its route health announcement disabled.

Impact:
Prefixes continue to exist in the BGP table even after disabling the virtual address (visible via imish with the "show ip bgp" command); which will continue to announce the prefix to configured peers.

Workaround:
Workaround would be to restart the dynamic routing process.

Fix:
BGP may no longer keeps announcing routes after disabling route health injection

707310-1 : DNSSEC Signed Zone Transfers of Large Zones Can Be Incomplete (missing NSEC3s and RRSIGs)

Component: Global Traffic Manager (DNS)

Symptoms:
It is possible that when performing a sufficiently large DNSSEC signed zone transfer (e.g., ~1 KB records) that the final packet (or several packets) of NSEC3s and RRSIGs could be missing from the zone. This issue can be detected using a free third-party tool such as ldns-verify-zone or some other DNSSEC validating tool.

Conditions:
-- Dynamic DNSSEC signing of zone transfers is configured for a given zone from an authoritative DNS Server (this could be on-box BIND, off-box BIND, etc.), or from DNS Express.

Impact:
The DNSSEC signed zone transfer could be incomplete, that is missing some NSEC3s and RRSIGs. An incomplete DNSSEC zone is considered an invalid zone.

Workaround:
There is no workaround at this time.

Fix:
DNSSEC signed zone transfers from general authoritative DNS Servers as well as from DNS Express are now complete regardless of the number of records in the zone.

707226-2 : DB variables to disable CVE-2017-5754 Meltdown/PTI mitigations

Component: TMOS

Symptoms:
Mitigations might CVE-2017-5754 Meltdown/PTI (Page Table Isolation) can negatively impact performance.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

Conditions:
Mitigations for CVE-2017-5754 Meltdown/PTI (Page Table Isolation) enabled.

Impact:
Meltdown/PTI mitigations may negatively impact performance.

Workaround:
Disable CVE-2017-5754 Meltdown/PTI mitigations.

To turn off mitigations for CVE-2017-5754 Meltdown/PTI, run the following command:

tmsh modify sys db kernel.pti value disable

Note: Turning off these mitigations renders the system vulnerable to CVE-2017-5754 Meltdown; but in order to take advantage of this vulnerability, they must already possess the ability to run arbitrary code on the system. Good access controls and keeping your system up-to-date with regards to security fixes will mitigate this risk on non-VCMP systems. vCMP systems with multiple tenants should leave these mitigations enabled.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

Fix:
On releases that provide mitigations for CVE-2017-5754 Meltdown/PTI, the protection is enabled by default, but can be controlled using db variables.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

707147-2 : High CPU consumed by asm_config_server_rpc_handler_async.pl

Component: Application Security Manager

Symptoms:
During a period of heavy learning from Policy Builder, typically due to Collapse Common elements, the backlog of events can cause a process to consume high CPU.

Conditions:
1) Automatic Policy Builder is enabled
2) An element is configured to "Always" learn new entities, and collapse common elements
3) An extended period of heavy learning due to traffic is enountered

Impact:
A process may consume high CPU even after the high traffic period is finished.

Workaround:
Kill asm_config_server.pl (This will not affect traffic)

Optionally modify one of the following
A) Learn "Always" to another mode
B) Turn off Collapse common URLs
C) Change from Automatic Learning to Manual

Workaround:
Might be workaround using an irule

Fix:
Corrected ASM multipart parsing.

706642-3 : wamd may leak memory during configuration changes and cluster events

Component: WebAccelerator

Symptoms:
wamd memory consumption increases over time.

Conditions:
-- AAM is provisioned so wamd is running.
-- User-initiated configuration change and/or other internal configuration or cluster events.

Impact:
wamd grows slowly over time, eventually crashing due to lack of memory. Temporary outage of services provided by wamd such as PDF linearization, invalidation, etc.

Workaround:
No workaround available.

Fix:
wamd n longer leaks memory during configuration changes and cluster events.

706631 : A remote TLS server certificate with a bad Subject Alternative Name should be rejected when Common Criteria mode is licensed and configured.

Component: Local Traffic Manager

Symptoms:
According to RFC2818, if the certificate sent by the TLS server has a valid Common Name, but the Subject Alternative Name does not match the Authenticate Name in the server-ssl profile, the connection should be terminated.

Conditions:
-- A server-ssl profile is enabled on a virtual server and has the 'authenticate-name' property set.

-- The TLS server presents a certificate in which the Subject Alternative Name does not match the configured authenticate-name.

-- Common Criteria mode licensed and configured.

Impact:
A TLS connection succeeds which should fail.

Workaround:
There is no workaround at this time.

Fix:
A remote TLS server certificate with a bad Subject Alternative Name is now rejected when Common Criteria mode is licensed and configured.

706423-2 : tmm may restart if an IKEv2 child SA expires during an async encryption or decryption

Component: TMOS

Symptoms:
TMM may discard an existing child-SA via timer during the moment it is in use for encryption or decryption. And in another spot, an error aborting negotiation can cause multiple timers associated with one child-SA, which fight one another.

Conditions:
Errors in IPsec config that fail negotiation can happen when a child-SA is in a state that does not manage timers correctly.

A config with short SA lifetime, causing frequent re-keying, can have the effect of searching for a race condition when expire happens during active use in crypto.

Impact:
TMM restarts, disrupting traffic and causing HA failover.

Workaround:
Ensure that the IPsec IKEv2 configuration in the IPsec policy is correct (the same) on both IPsec peers. Also, ensure SA lifetime has longer duration, instead of merely seconds. (The default is one day.)

Fix:
Now we ensure only one timer can be associated with a child-SA related to short-term progress toward maturity during negotiation, even if an error happens.

Now we also ensure a child-SA is safe during async crypto operations, even if they expire while currently in use.

706374-2 : Heavy use of APM Kerberos SSO can sometimes lead to memory corruption

Component: Access Policy Manager

Symptoms:
Kerberos SSO under high load can sometimes lead to system instability.

Conditions:
APM users using Kerberos SSO to access backend resources.

Impact:
This might result in unpredictable behavior such as memory corruption or core. However, the occurrence is rare since it only impacts concurrent DNS SRV requests to resolve different KDCs.

Workaround:
There is no workaround.

Fix:
Stability problems in DNS lookups in APM Kerberos SSO (S4U) have been corrected.

706354-1 : OPT-0045 optic unable to link

Component: TMOS

Symptoms:
The OPT-0045 optical transceiver when inserted into a 40G port does not function. The following error appears in /var/log/ltm:
Invalid module for bundle configuration of interface <portNumber>.0.

Conditions:
OPT-0045 in a 40G port.

Impact:
Optic does not work; interface does not come up.

Workaround:
None.

Fix:
This release supports the OPT-0045 optical transceiver.

706305-2 : bgpd may crash with overlapping aggregate addresses and extended-asn-cap enabled

Component: TMOS

Symptoms:
bgpd may crash on a BIG-IP system configured for dynamic routing announcing multiple overlapping aggregate-addresses with extended asn capabilities enabled.

Conditions:
- BGP enabled on route-domain
- BGP configured to announce several overlapping aggregate-addresses
- BGP configured with extended-asn-cap enabled.

Impact:
Inability for the unit to use BGP

Workaround:
Disabling extended-asn-cap or not announcing multiple overlapping aggregate addresses may allow to workaround this issue.

Fix:
bgpd no longer crashes with overlapping aggregate addresses and extended-asn-cap enabled

706128-1 : DNSSEC Signed Zone Transfers Can Leak Memory

Component: Global Traffic Manager (DNS)

Symptoms:
TMM might leak memory when performing DNSSEC signed zone transfers. You can detect this issue by examining system memory before and after performing zone transfers.

For example:

tmsh show sys memory raw | grep dnssec

Conditions:
-- Dynamic DNSSEC signing of zone transfers is configured for a given zone from an authoritative DNS Server (this could be on-box BIND, off-box BIND, etc) or from DNS Express.

Impact:
TMM leaks memory related to the signed zone transfer.

Workaround:
There is no workaround at this time.

Fix:
TMM no longer leaks DNSSEC zone transfer related memory.

706104-2 : Dynamically advertised route may flap

Component: TMOS

Symptoms:
ZebOS may repeatedly add and delete the routes from protocol daemons. This may cause the protocol daemons to delete and re-advertise the default route.

Conditions:
- Dynamic routing in use
- Kernel routes redistributed into a routing protocol
- Static route configure in TMOS
- Route advertisement enabled on the virtual-address that's the same as the static route

Impact:
Route flapping may cause instability in the network, including inability to reach the default network advertised by the BIG-IP.

Workaround:
Since the static route will be redistributed in the same way as the virtual-address, there is no need to enable route-advertisement on the VIP virtual-address. Disabling this will resolve the problem.

The problem will also be resolved by moving the route from tmsh into ZebOS.
- In imish config mode, "ip route <route> <gateway>"
- In tmsh, "delete net route <route>"

Fix:
Configuring a static route in TMOS and enabling route-advertisement on the same virtual-address no longer causes route flapping in ZebOS.

706102-3 : SMTP monitor does not handle all multi-line banner use cases

Component: Local Traffic Manager

Symptoms:
An SMTP monitor does not handle all multi-line banner use cases, such as when the banner is physically split across two packets. This issue is due to attempting to parse the banner value from the first packet without a portion of the banner value that may arrive in a second packet.

Conditions:
An SMTP monitor is configured; and uses a multi-line banner; and the SMTP monitor banner is split across two physical packets.

Impact:
The SMTP monitor sends an RST after the first packet, and marks the resource down.

Workaround:
Use an SMTP monitor with a single-line banner. Or, rather than using an SMTP monitor, instead use a TCP monitor with send/recv strings.

Fix:
An SMTP monitor handles all use cases that include a multi-line banner.

Solution Article: K62750376

705794-1 : Under certain circumstances a stale HTTP/2 stream might cause a tmm crash

Component: Local Traffic Manager

Symptoms:
A HTTP/2 stream is getting overlooked when cleaning up a HTTP/2 flow.

Conditions:
The only known condition is that the closing_stream is not empty. Exact entrance conditions are not clear.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

Fix:
HTTP/2 flows are now properly cleaned up to prevent a tmm crash.

705611-1 : The TMM may crash when under load when configuration changes occur when the HTTP/2 profile is used

Component: Local Traffic Manager

Symptoms:
The TMM may later crash after a configuration change done under load if the HTTP/2 profile is used.

Conditions:
A configuration change occurs. The configuration change is large enough, or the TMM load large enough that the change is not synchronous. The change involves a HTTP/2 profile.

Data traffic progresses through a partially initialized HTTP/2 virtual server, potentially causing a later crash.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

Fix:
Large configuration changes to the TMM involving a HTTP/2 profile will no longer potentially cause a TMM crash.

705503-1 : Context leaked from iRule DNS lookup

Component: Global Traffic Manager (DNS)

Symptoms:
The memory usage increases, and stats are inaccurate.

Conditions:
Call RESOLV::lookup from an iRule.

Impact:
Memory leak that accumulates over time and inaccurate stats.

Workaround:
There is no workaround other than not using RESOLV::lookup in an iRule.

Fix:
Memory leak no longer occurs.

705476-4 : Appliance Mode does not follow design best practices

Solution Article: K28003839

705112-1 : DHCP server flows are not re-established after expiration

Component: Local Traffic Manager

Symptoms:

Conditions:
- More than one DHCP servers configured for a DHCP virtual.
- Server flows timeout in 60 seconds

Impact:
DHCP server traffic not load balanced.

Workaround:
None.

Fix:
A new logic to re-establish server flows is introduced to ensure a relay agent will have all DHCP servers connected.

705037-3 : System may exhibit duplicate if_index, which in some cases lead to nsm daemon restart

Component: TMOS

Symptoms:
It is possible for the BIG-IP system to present duplicate if_index statistics of network objects, either viewed internally or polled via SNMP.

Conditions:
-- High availability (HA) configuration.
-- Tunnels configured.
-- If dynamic routing is configured, additional impact may be noted.

Impact:
-- Unreliable or confusing statistics via SNMP polling.

-- If dynamic routing is also configured, possible nsm daemon restart, which may lead to loss of dynamic routes.

Workaround:
None.

Fix:
System no longer exhibits duplicate if_index statistics.

704804-2 : The NAS-IP-Address in RADIUS remote authentication is unexpectedly set to the loopback address

Component: TMOS

Symptoms:
The NAS-IP-Address in RADIUS remote authentication requests is set to the loopback address, not the management IP.

Conditions:
This applies to remote authentication for the control plane, not APM.

Impact:
Login may be impacted.

Workaround:
There is no workaround at this time.

Fix:
NAS-IP-Address Attribute is now set correctly when the the BIG-IP system is configured to use RADIUS authentication.

704733-2 : NAS-IP-Address is sent with the bytes in reverse order

Component: TMOS

Symptoms:
The NAS-IP-Address has the address of the local device sent with the bytes in reverse order (e.g., 78.56.30.172, where 172.30.56.78 is expected).

Conditions:
-- This affects IPv4 addresses only.
-- BIG-IP system is configured for RADIUS authentication.

Impact:
The server may be configured to check the NAS-IP-Address before allowing logins, in which case it would fail.

Workaround:
There is no workaround at this time.

Fix:
This has been corrected.

704666-2 : memory corruption can occur when using certain certificates

Component: Local Traffic Manager

Symptoms:
If a certificate has an extremely long common name, or an extremely long alternative name and is attached to an SSL profile, memory corruption can occur when loading the profile.

Conditions:
An SSL profile is loaded with a certificate containing an extremely long common name or subject alternative name.

Impact:
TMM could crash.

Workaround:
Do not use certificates with extremely long common names

Fix:
A length check has been added to avoid corruption when using extremely long common names.

704580-3 : apmd service may restart when BIG-IP is used as SAML SP while processing response from SAML IdP

Solution Article: K05018525

704524-2 : [Kerberos SSO] Support for EDNS for kerberos DNS SRV queries

Component: Access Policy Manager

Symptoms:
Kerberos DNS SRV requests do not contain EDNS headers. Without this header, DNS server truncates the UDP responses if it is greater than 512 bytes, causing the DNS request to be re-sent on TCP connections. This results in unnecessary round trips in order to resolve DNS SRV queries.

Conditions:
APM users using Kerberos SSO to access backend resources.

Impact:
Increased latency of HTTP request processing. If the number of APM users is large, then this issue is magnified.

Workaround:
There is no workaround at this time.

Fix:
Kerberos DNS SRV requests now support EDNS0 so that UDP responses greater than 512 bytes can be received correctly, eliminating delays caused by TCP retransmission.

704483 : CVE-2017-5753 (Spectre Variant 1)

Solution Article: K91229003

704449-4 : Orphaned tmsh processes might eventually lead to an out-of-memory condition

Component: TMOS

Symptoms:
Occasionally, tmsh processes are orphaned when a user connects to the BIG-IP system via SSH, runs commands, and then quits the session or disconnects.

An orphaned tmsh process will have a parent pid (PPID) of 1. You can check for orphaned tmsh processes using the following shell command:

/bin/ps -o pid,ppid,comm -C tmsh
PID PPID COMMAND
8255 1 tmsh

If this issue occurs often enough, it might cause the BIG-IP system to run out of memory.

Conditions:
-- Using tmsh to connect to the BIG-IP system via SSH.
-- Running commands.
-- Quitting the session or disconnecting.

Impact:
Orphaned tmsh processes are created, which might eventually lead to an out-of-memory condition, if it occurs often enough.

Workaround:
There are several workarounds for this issue:

-- Change the default shell to bash for users that are going to use the script.
-- Use iControl.
-- Halt orphaned tmsh processes.

Fix:
tmsh processes are no longer orphaned when a user connects to the BIG-IP system via SSH, runs commands, and then quits the session or disconnects under these conditions.

704381-3 : SSL/TLS handshake failures and terminations are logged at too low a level

Component: Local Traffic Manager

Symptoms:
SSL/TLS handshake failures and terminations are being logged at too low of a level (INFO).

Conditions:
-- SSL/TLS connections are received or sent.
-- Handshake failures are logged.

Impact:
Sometimes other errors are produced, and the cause is a SSL/TLS handshake failure, but this failure is not being logged.

Workaround:
There is no workaround.

Fix:
SSL/TLS handhake failures and terminations are now logged at a higher level (WARNING).

704336-3 : Updating 3rd party device cert not copied correctly to trusted certificate store

Component: TMOS

Symptoms:
When a BIG-IP admin updates the Device Certificate which also includes multiple CA intermediate and root certificates, it's expected that the new Device Certificate and its trust chain certificates are written to /config/big3d/client.crt and /config/gtm/server.crt. However, if the new Device Certificate is signed by a third party, only the Device Certificate is copied to client.crt and server.crt, even though root and intermediate certificates are written to /config/httpd/conf/ssl.crt/server.crt.

Conditions:
Updating Device certificate which also includes multiple intermediate and root certificates.

Impact:
The Trusted Device and Trusted server Certificates do not include intermediate CA and root certificates.

Workaround:
Manually copy/append the missing intermediate and root certificate to /config/big3d/client.crt and /config/gtm/server.crt.

Fix:
The fix will now add all the intermediate and root certificate including device certificate to Trusted Server and Trusted Device certificate bundle.

704282-3 : TMM halts and restarts when calculating BWC pass rate for dynamic bwc policy

Component: TMOS

Symptoms:
Rarely, TMM halts and restarts when calculating the BWC pass rate for dynamic bwc policy.

Conditions:
-- Using BWC dynamic bwc policy.
-- Fair share rate is low.

For this to happen, the fair share rate of the instance of dynamic policy has to be less than than 32 times the average packet size of the instance of policy.

For example, if the average packet size is 1 KB, then the fair share would be under 32 KB.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
F5 does not recommend running the BWC under 64Kbps.

Either decrease the number of subscribers or increase the max-rate of dynamic policy.

Fix:
TMM no longer halts and restarts when calculating the BWC pass rate for dynamic bwc policy when fair share rate is low.

704247-3 : BIG-IP software may fail to install if multiple copies of the same image are present and have been deleted

Conditions:
-- Have multiple copies of the same image .iso in the /shared directory on a BIG-IP system.
-- Delete one of them.

Impact:
Installation attempt of the remaining image(s) might fail.

Workaround:
Restart the lind process, so the installation can continue.

Fix:
The BIG-IP system now installs an image if multiple copies of the same image are present and have been deleted

Solution Article: K52171282

704143-2 : BD memory leak

Component: Application Security Manager

Symptoms:
A BD memory leak.

Conditions:
websocket traffic with specific configuration

Impact:
Resident memory increases, swap getting used.

Workaround:
Make sure the web socket violations are not due to bad websocket URL configuration, that they are turned on in Learn/Alarm or block and that there is a local logger configured and attached.

704073-3 : Repeated 'bad transition' OOPS logging may appear in /var/log/ltm and /var/log/tmm

Solution Article: K24233427

Component: Local Traffic Manager

Symptoms:
'bad transition' OOPS messages may be repeatedly logged to /var/log/ltm and /var/log/tmm over time, polluting the log files.

Conditions:
Although there are no definitive user-discernible conditions, use of SSL functionality might increase the likelihood of logging.

Impact:
Log pollution and potential for performance degradation.

Workaround:
Suppress the logging using the following command:
tmsh modify sys db tmm.oops value silent

Fix:
The 'bad transition' OOPS logging has been demoted to internal, debug builds only.

703984-2 : Machine Cert agent improperly matches hostname with CN and SAN

Component: Access Policy Manager

Symptoms:
MacOS Machine certificate agent matches the configured hostname with the actual hostname upon a beginning partial string match.

Conditions:
MacOS APM client using Machine Certificate Check agent.

Impact:
Hostname match may be incorrect in these cases.

Workaround:
There is no workaround at this time.

Fix:
The MacOS machine certificate check agent now matches on the whole host string rather than a sub string.

Solution Article: K45611803

703914-1 : TMM SIGSEGV crash in poolmbr_conn_dec.

Component: Local Traffic Manager

Symptoms:
TMM cores in poolmbr_conn_dec function.

Conditions:
A connection limit is reached on a VS having an iRule using LB::reselect and a pool using request queueing.

Impact:
TMM core, traffic interruption, possible failover.

Workaround:
Do not use LB::reselect, disable request queueing on a pool associated with the VS.

Fix:
TMM correctly handles LB:reselect on virtual servers with pools using request queueing.

703869-1 : Waagent updated to 2.2.21

Component: TMOS

Symptoms:
Microsoft updates waagent via an opensource process, but it is not compatible with BIG-IP software, and so cannot be upgraded outside of BIG-IP releases. Without this, Microsoft will not support older releases of BIG-IP systems in their environment.

Conditions:
Using Microsoft Azure.

Impact:
Microsoft does not support the version of waagent shipped as part of BIG-IP software.

Workaround:
None.

Fix:
Waagent was updated to 2.2.21 from Microsoft along with F5 changes for compatibility with BIG-IP software.

703835-4 : When using SCP into BIG-IP systems, you must specify the target filename

Solution Article: K82814400

703793-1 : tmm restarts when using ACCESS::perflow get' in certain events

Component: Access Policy Manager

Symptoms:
tmm will restart when using 'ACCESS::perflow get' if the per-request policy has not been started yet.

Conditions:
Use 'ACCESS::perflow get' iRule in an event that runs before the per-request policy (e.g., CLIENT_ACCEPTED).

Impact:
tmm cores and traffic flow will be interrupted while it restarts.

Workaround:
None.

Fix:
Initialization of certain variables was reworked so that the iRule command will not cause a core anymore if the per-flow value is unavailable due to the per-request policy not having been started yet.

703761-1 : Disable DSA keys for public-key and host-based authentication in Common Criteria mode

Component: TMOS

Symptoms:
On a BIG-IP system configured for Common Criteria (CC) mode, DSA keys can still be used for key-based authentication to the BIG-IP system.

Conditions:
-- Running a CC release with CC Mode enabled.
-- Attempt to SSH-connect to the BIG-IP system from another system with a DSA key.
-- That DSA key is present in the BIG-IP system's authorized_keys file.

Impact:
If the key is in the BIG-IP system's authorized_keys file, public-key authentication succeeds, when DSA authentication should be disabled in CC mode.

Workaround:
There is no workaround at this time.

Fix:
DSA SSH keys are now disabled for public-key and host-based authentication in Common Criteria mode, as expected.

703580 : TLS1.1 handshake failure on v12.1.3 vCMP guest with earlier BIG-IP version on vCMP host.

Component: Local Traffic Manager

Symptoms:
TLS1.1 handshake failure on guest. The following error appears in /var/log/ltm:

Conditions:
-- Using the VIPRION 42xx/43xx and B21xx blades.
-- Running BIG-IP software earlier than v12.1.3 (for example v12.1.2-hf2) on the vCMP host system.
-- Deploying vCMP guest running v12.1.3.
-- Using TLS1.1.

Impact:
TLS1.1 handshake fails on the guest.

Workaround:
Use the same software version on the vCMP host and vCMP guests.

Fix:
TLS1.1 handshake no longer fails running v12.x/v13.x vCMP guest with earlier BIG-IP software version on vCMP host.

702946-2 : Added option to reset staging period for signatures

Component: Application Security Manager

Symptoms:
In cases where a staging period was started, but no traffic passed through security policy, you might want to reset the staging period when traffic starts, but there is no option to do so.

Conditions:
Staging enabled for signatures in policy.

Impact:
There is a suggestion to enforce the signature before any traffic can influence this decision.

Workaround:
If all signatures are staged, you can enforce them all, and then enable staging again.

Note: Apply policy is required between actions.

Fix:
Added option to reset the staging period for all or specific signatures. In modal windows shown after clicking 'Change properties...' on the Policy Signatures screen, when 'No' is not selected for 'Perform Staging', the system presents a checkbox: Reset Staging Period.

702873-3 : Windows Logon Integration feature may cause Windows logon screen freeze

Component: Access Policy Manager

Symptoms:
Windows Logon Integration feature might cause a Microsoft Windows logon screen freeze, making Windows OS unresponsive to any client end user actions.

Conditions:
-- Client user putting laptop into sleep mode and waking it up multiple times.
-- Possibly, only Windows 10 is affected.

Impact:
Logon screen may hang, not allowing client user to type in credentials.

Workaround:
Reinstall EdgeClient without the Windows Logon Integration Feature.

Fix:
Previously, the Windows Logon Integration feature sometimes caused the Windows Logon screen to freeze. Now, this issue has been fixed.

As a side effect of the fix, the Logon screen now shows duplicates of the pre-logon VPN Entries, which might be confusing for client users. One duplicate comes from the Microsoft Credentials Provider. For information on how to disable the default Microsoft Credentials Provider, see the Microsoft Windows article: How to disable additional credential providers :: https://social.technet.microsoft.com/Forums/windows/en-US/9c23976a-3e2b-4b71-9f19-83ee3df0848b/how-to-disable-additional-credential-providers.

702738 : Tmm might crash activating new blob when changing firewall rules

Solution Article: K32181540

Component: Advanced Firewall Manager

Symptoms:
TMM crashes with core when changing firewall rules. TMM can enter a crash-loop, so it will crash again after restarting.

Conditions:
Updating, removing, or adding firewall rules.

Specific characteristics of change that can cause this issue are unknown; this issue occurs rarely.

Impact:
Data traffic processing stops.

Workaround:
There are two workaround options:
Option A
1. Delete all policies.
2. Create them again without allowing blob compilation.
3. Repeat steps 1 and 2 until all the policies have been created (enable on-demand-compilation).

Option B
Modify all the rules simultaneously.

For example, the following steps will resolve this issue:
1. Enable on-demand-compilation
2. Select an IP address that is not used in any rules, e.g., 1.1.1.1.
3. Add that IP address to all the rules/source in all of the policies. To do so, run the following command for each policy:
tmsh modify security firewall policy POLICY_NAME rules modify { all { source { addresses add { 1.1.1.1 } } } }

4. Delete the IP address (restore rules) in all of the policies. To do so, run the following command for each policy:
tmsh modify security firewall policy POLICY_NAME rules modify { all { source { addresses delete { 1.1.1.1 } } } }
5. Disable on-demand-compilation. Doing so starts new blob compilation.

Fix:
TMM no longer crashes when changing firewall rules.

702490-4 : Windows Credential Reuse feature may not work

Component: Access Policy Manager

Symptoms:
Windows Credential Reuse feature may not work requiring that the EdgeClient end user enter credentials in the EdgeClient login window as well as at the Microsoft Windows logon screen, instead of getting Single Sign-On (SSO).

The logterminal.txt file contains messages similar to the following:

<Date and time>, 1312,1320,, 48, \certinfo.cpp, 926, CCertInfo::IsSignerTrusted(), the file is signed by 3rd party certificate
<Date and time>, 1312,1320,, 1, \certinfo.cpp, 1004, CCertInfo::IsSignerTrusted(), EXCEPTION - CertFindCertificateInStore() failed, -2146885628 (0x80092004) Cannot find object or property.
<Date and time>, 1312,1320,, 1, \certinfo.cpp, 1009, , EXCEPTION caught
<Date and time>, 1312,1320,, 1, \CredMgrSrvImpl.cpp, 256, IsTrustedClient, EXCEPTION - File signed by untrusted certificate
<Date and time>, 1312,1320,, 1, \CredMgrSrvImpl.cpp, 264, , EXCEPTION caught
<Date and time>, 1312,1320,, 1, \CredMgrSrvImpl.cpp, 360, GetCredentials, EXCEPTION - Access Denied - client not trusted

Conditions:
-- Using a specific combination of versions of F5 Credential Manager Service and EdgeClient on Windows systems.
-- The Reuse Credential option is enabled in the Connectivity Profile.

Impact:
The EdgeClient end user must retype credentials in EdgeClient login windows instead of having the login occur without requiring credentials, as SSO supports.

Workaround:
There is no workaround at this time.

Fix:
Previously, in some situations, Windows Credential Reuse did not work, requiring the EdgeClient end user to log in separately. This issue has been fixed.

702487-1 : AD/LDAP admins with spaces in names are not supported

Component: Access Policy Manager

Symptoms:
If admin is imported from Active Directory (AD) or Lightweight Directory Access Protocol (LDAP) and the name contains spaces, Visual Policy Editor (VPE), import/export/copy/delete, etc., fail, and post an error message similar to the following: sourceMCPD::loadDll User 'test user' have no access to partition 'Common'.

Note: Names containing spaces are not supported on BIG-IP systems.

Conditions:
-- Admin name containing spaces is imported from AD or LDAP.
-- Attempt to perform operations in VPE.

Impact:
VPE, import/export/copy/delete do not work.

Workaround:
There is no workaround other than to not use admin names containing spaces.

Fix:
VPE and utilities operations are now supported, even for admins with spaces in names. However, F5 recommends against using spaces in admin names, and recommends that you modify the admin name to remove the spaces.

702450-4 : The validation error message generated by deleting certain object types referenced by a policy action is incorrect

Component: Local Traffic Manager

Symptoms:
When deleting certain objects that are referenced by policy actions, you may see a validation error like this:

# tmsh delete ltm virtual test-vs
01071726:3: Cannot delete policy action '/Common/test-vs'. It is in use by ltm policy '/Common/test-policy'.

The referenced object is not a "policy action" in this case, but is a virtual server.

Conditions:
LTM policies must be in use, and at least one policy action must forward to an object. The user must attempt to delete that object.

Impact:
Possible confusion at the error message.

Workaround:
There is no workaround at this time.

Fix:
Made the error message accurately reflect what the user was attempting to delete.

702278-3 : Potential XSS security exposure on APM logon page.

Component: Access Policy Manager

Symptoms:
Potential XSS security exposure on APM logon page.

Conditions:
-- A LTM virtual server with an Access Policy assigned to it.
-- The Access Policy is configured to use a 'Logon Page' VPE agent, followed by AAA agent with 'Max Logon Attempts Allowed' set to a value greater than 1.

Impact:
Potential XSS security exposure.

Workaround:
1. Using APM Advance Customization UI, remove setOrigUriLink(); call in logon.inc from the next JS function:

370 {
371 var header = document.getElementById("credentials_table_header");
372 var softTokenHeaderStr = getSoftTokenPrompt();
373 if ( softTokenHeaderStr ) {
374 header.innerHTML = softTokenHeaderStr;
375 }
376 setFormAttributeByQueryParams("auth_form", "action", "/subsession_logon_submit.php3");
377 setFormAttributeByQueryParams("v2_original_url", "href", "/subsession_logon_submit.php3");
378 // ===> REMOVE THIS ONE setOrigUriLink();
----

Fix:
Potential security exposure has been removed from APM logon page.

702151-2 : HTTP/2 can garble large headers

Component: Local Traffic Manager

Symptoms:
The HTTP/2 filter may incorrectly encode large headers.

Conditions:
A header that encodes to larger than 2048 bytes may be incorrectly encoded.

Impact:

Component: Application Security Manager

Symptoms:
In rare circumstance, when Policy Builder restarts continuously (in response to a different issue in which there are many shmem segments allocated and used by tmm), ASM-config Event Dispatcher memory usage grows uncontrollably.

Conditions:
In rare circumstances, Policy Builder restarts continuously (in response to a different issue in which there are many shmem segments allocated and used by tmm).

Impact:
ASM-config Event Dispatcher memory usage grows continuously until the device eventually fails over.

Workaround:
Restart asm_config_server on all devices using the following command:
killall asm_config_server.pl

701841-1 : Unnecessary file recovery_db/conf.tar.gz consumes /var disk space

Component: Application Security Manager

Symptoms:
A file, /ts/var/install/recovery_db/conf.tar.gz ,is saved unnecessarily during UCS file save, and consumes /var disk space.

Conditions:
UCS file is saved.

Impact:
The /var filesystem can become full; this may degrade system performance over time, and can eventually lead to traffic disruptions.

Workaround:
Manually delete /ts/var/install/recovery_db/conf.tar.

Solution Article: K18352029

701680-1 : MBLB rate-limited virtual server periodically stops sending packets to the server for a few seconds

Component: Service Provider

Symptoms:
Applying rate-limiting to MBLB SIP or Diameter virtual servers might cause the virtual server to periodically stop sending packets to the pool member server for a few seconds.

Conditions:
-- MBLB SIP or Diameter virtual server.
-- Rate-limited is applied.

Impact:
The virtual server might intermittently stop sending packets to the pool member server for a few seconds.

Workaround:
There is no workaround at this time.

Fix:
MBLB rate-limited virtual server now correctly sends packets to the server.

701678-1 : Non-TCP and non-FastL4 virtual server with rate-limits may periodically stop sending packets to server when rate exceeded

Component: Local Traffic Manager

Symptoms:
TMM may periodically stop sending packets to the server for a few seconds when the configured virtual server rate-limited value is exceeded.

Conditions:
-- Virtual configured with rate-limit.
-- Uses a UDP profile (i.e., not using TCP or FastL4).
-- The idle-timeout is set to immediate.

Impact:
The virtual server might intermittently stop sending packets to the pool member server for a few seconds.

701626-1 : GUI resets custom Certificate Key Chain in child client SSL profile

Solution Article: K16465222

Component: TMOS

Symptoms:
In the GUI, editing a client SSL profile or selecting a different parent profile changes the Certificate Key Chain to default (i.e., /Common/default.crt and /Common/default.key).

Conditions:
This happens in the following scenario:

1. Using the GUI, create a client SSL profile.
2. Configure the new profile to inherit from a client SSL profile other than the default, clientssl.
3. Click the Custom box for Certificate Key Chain and select a different cert and key from the default.
4. Click Update.
5. In the GUI, change any setting in the newly created profile, or select a different parent profile (but not the clientssl profile).
6. Click Update again.

Impact:
The system resets Certificate Key Chain to default, even though the Custom box is checked.

Workaround:
To work around this issue in the GUI, click the Custom checkbox next to the 'Certificate Key Chain' option in the parent profile. This will set the value of inherit-certkeychain to false , preventing the issue from occurring.

You can also use tmsh to update parent profile settings to avoid the occurrence of this issue..

Fix:
GUI no longer resets custom Certificate Key Chain in child client SSL profiles.

701609 : Static member of pool with FQDN members may revert to user-disabled after being re-enabled

Component: Local Traffic Manager

Symptoms:
Within an LTM pool containing both FQDN members and members configured with static IP addresses; a statically-configured member that had been disabled (session = user-disabled) and then re-enabled (session = user-enabled) may become disabled again after making other changes affecting the state of other FQDN members of the pool.

Conditions:
This may occur under the following conditions:
- An LTM pool containing a mix of FQDN and statically-configured members.
- A statically-configured pool member is disabled (session = user-disabled) and then re-enabled (session = user-enabled).
- Other changes occur which affect the availability of FQDN pool members.
For example, if a route to an FQDN pool member is deleted and recreated, a previously-disabled statically-configured member may revert to a disabled state.

Depending on circumstances, the issue may only occur once after BIG-IP, TMM, bigd, or a related daemon restarts.

Impact:
A pool member may be unexpectedly disabled after being re-enabled, and thus would not receive traffic.

Workaround:
It may be possible to work around this issue by disabling and re-enabling the statically-configured pool member again.

Fix:
Statically-configured pool members of a pool that also contains FQDN members remain enabled after being manually disabled then re-enabled. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

701538-1 : SSL handshake fails for OCSP, TLS false start, and SSL hardware acceleration configured

Component: Local Traffic Manager

Symptoms:
SSL handshake fails if the client initiates the handshake with TLS false start (specifically, client SSL sends the SSL record data to the server before the Server sends out the CSS is FINISHED notification).

Conditions:
1. Client initiates the SSL handshake with False Start.
2. The BIG-IP system has SSL hardware acceleration enabled (which is default for for non-virtual edition (VE) versions).

Impact:
The BIG-IP system sends the RST to tear down the connection in TLS false start.

Workaround:
There are no true workarounds. You must disable one of the conditions to workaround the issue:

-- Disable TLS False Start. (Note: this might not be feasible because it needs to be done on all clients.)
-- Disable SSL acceleration.
-- Disable AES-GCM ciphers in the client SSL profile. Without AES-GCM, clients do not try to use TLS false start and still be able to use (EC)DHE.

Fix:
The system no longer processes application data before verifying that the finished message arrives and handshake is complete.

Solution Article: K08613310

701327-1 : failed configuration deletion may cause unwanted bd exit

Component: Application Security Manager

Symptoms:
Immediately after the deletion of a configuration fails, bd exists.

Conditions:
When deleting a configuration fails.

Impact:
Unwanted bd restart.

Workaround:
None.

Fix:
bd will exit upon a failed configuration only when configured to exit on failure.

701253-3 : TMM core when using MPTCP

Solution Article: K16248201

701249-2 : RADIUS authentication requests erroneously specify NAS-IP-Address of 127.0.0.1

Component: TMOS

Symptoms:
RADIUS requests from BIG-IP have attribute NAS-IP-Address = 127.0.0.1, which might cause authentication to fail.

The NAS-IP-Address is essentially the resource an end user client is trying to authenticate to. This is typically the management IP address of the BIG-IP system, but the BIG-IP system always sends 127.0.0.1 instead. That might fail or it might work, depending on how the server is configured.

Conditions:
This is an issue for all RADIUS authentication requests that use the attribute NAS-IP-Address.

Note: This affects remote control plane authentication only, not APM or other uses of RADIUS.

Impact:
BIG-IP system always sends 127.0.0.1 instead of the BIG-IP system's management IP address. RADIUS server might not service the request, so authentication fails.

Workaround:
There is no workaround.

701202-1 : SSL memory corruption

Solution Article: K35023432

Component: Local Traffic Manager

Symptoms:
In some instances random memory can be corrupted causing TMM core.

Conditions:
SSL is configured (either client-ssl or server-ssl) and SNI is used to select a non-default profile.

Impact:
TMM crash, disrupting traffic.

Workaround:
There is no workaround at this time.

Fix:
The memory corruption issue has been fixed.

701039 : Requests do not appear in local logging due to rare file descriptor exhaustion

Component: Application Security Manager

Symptoms:
In an extremely rare circumstance, requests do not appear in local logging due to file descriptor exhaustion in asmlogd.

Conditions:
-- ASM configured.
-- ASM policy with an associated 'Log all requests' logging profile.
-- Requests sent to virtual server.
-- View Request Log.

Impact:
Requests do not appear in local logging.

Workaround:
Restart ASM, or pkill -f asmlogd.

Fix:
Requests appear in local logging correctly.

700889-2 : Software syncookies without TCP TS improperly include TCP options that are not encoded

Solution Article: K07330445

Component: Local Traffic Manager

Symptoms:
When sending a software syncookie and there is no TCP timestamp option, tmm sends back TCP options like window scaling (WS), sackOK, etc. The values for these options are encoded in the timestamp field which is not sent. When the final ACK of the 3WHS arrives (without a timestamp), there is no way to know that the BIG-IP system negotiated the use of SACK, WS and other options that were encoded in the timestamp. This will leave the client believing that options are enabled and the BIG-IP believing that they are not.

Conditions:
TCP timestamps are disabled by the client, or in the TCP profile.

Impact:
In one known case, the client was Windows 7 which apparently disables timestamps by default. Users might experience poor connection performance because the client believed it was using WS, and that the BIG-IP system would scale up the advertised window. However, the BIG-IP system does not using WS in this case, and used the window size from the TCP header directly, causing the BIG-IP system to send small packets (believing it had filled the window) and wait for a response.

Workaround:
Specifically prevent the WS issue by lowering the send_buffer_size and receive_window_size to less than or equal to 65535.

Fix:
Added dependency between the window scale option and the timestamp option in a SYN/ACK response.

700862-2 : tmm SIGFPE 'valid node'

Solution Article: K15130240

Component: Local Traffic Manager

Symptoms:
A rare TMM crash with tmm SIGFPE 'valid node' may occur if the host is unreachable.

Conditions:
The host is unreachable.

Impact:
Lack of stability on the device. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
This fix handles a rare TMM crash when the host is unreachable.

700827-2 : B2250 blades may lose efficiency when source ports form an arithmetic sequence.

Component: TMOS

Symptoms:
Traffic imbalance between tmm threads. You might see the traffic imbalance by running the following command:
tmsh show sys tmm-traffic

Conditions:
Source ports used to connect to B2250 blade form an arithmetic sequence.

For example, some servers always use randomly selected even source port numbers. This means the 'stride' of the ports selected is '2'. Because a sorted list of the ports yields a list like 2, 4, 6, 8... 32002, 32004. It is 'striding' over the odd ports; thus, a port stride of 2.

Impact:
Traffic imbalance between tmm threads may result in sub-optimal performance.

Workaround:
Randomize source ports when connecting via a BIG-IP system.

Fix:
This release introduces a new variable mhdag.pu.table.size.multiplier. Setting it to 2 or 3 mitigates the issue.

700812-2 : asmrepro recognizes a BIG-IP version of 13.1.0.1 as 13.1.0 and fails to load a qkview

Component: Application Security Manager

Symptoms:
asmrepro recognizes a BIG-IP version of 13.1.0.1 as 13.1.0 and fails to load a qkview.

Conditions:
Try to deploy a qkview on a BIG-IP using the asmrepro tool
while BIG-IP has a 4 element version like 13.1.0.1.

Impact:
Cannot deploy a 4 element version qkview on a BIG-IP using the asmrepro tool.

Workaround:
n/a

Fix:
asmrepro now handles the version number properly.

700783-3 : Machine certificate check does not check against all FQDN hostnames

Component: Access Policy Manager

Symptoms:
macOS machine can be on multiple networks simultaneously, so it might have multiple hostnames. Machine certificate check does not check against all FQDN hostnames. This causes failure in certain scenarios.

Conditions:
-- macOS configuration with multiple hostnames.
-- The 'match FQDN with subject alt name' option is specified for machine certificate check.

Impact:
Machine cert check might fail.

Workaround:
No workaround at this time.

Fix:
Previously, with a macOS system that had multiple hostnames, the machine certificate check could not check against all hostnames, causing failures in some scenarios. Now, the machine certificate check compares all hostnames on macOS devices.

700780-4 : F5 DNS Relay Proxy service now warns about and clears truncated flag in proxied DNS responses

Component: Access Policy Manager

Symptoms:
F5 DNS Relay Proxy service does not support DNS-over-TCP requests, so if, in some configuration, the client resolver decides to use TCP for DNS resolution, this packet is not re-routed/proxied by the DNS Relay Proxy service, and may be causing DNS to be resolved using an incorrect DNS server (where the system decides to send it).

Typically, if a client receives DNS response with the TC flag set, it retries using TCP. Clearing the TC flag makes client resolver not use TCP at all, preventing DNS packets leakage.

Conditions:
-- DNS server responds with TC flag set in DNS response packet.
-- Windows only is affected.

Impact:
DNS resolution may not work as designed, as the system might send a packet to an incorrect DNS server.

Workaround:
None.

Fix:
Now F5 DNS Relay Proxy service clears TC flag in all proxied packets, preventing client DNS resolvers from using TCP. An appropriate log entry is printed into the service's log.

700757-2 : vcmpd may crash when it is exiting

Component: TMOS

Symptoms:
vcmpd may crash when it is exiting. The system logs an error message similar to the following in /var/log/ltm:

err vcmpd[14604]: 01510000:3: Uncaught exception: basic_string::_S_create

It's possible that vcmpd will then not start up, logging errors similar to the following in /var/log/ltm:

umount(/var/tmstat-vcmp/<guest name>) failed: (16, Device or resource busy

Conditions:
vCMP must be in use.

Impact:
vcmpd cores, but does so when already exiting. It is possible that vcmpd will then be unable to restart itself, and will need to be manually restarted.

Workaround:
If vcmpd cannot restart itself, you can manually restart it by running the following command:

tmsh restart sys service vcmpd

Fix:
Prevented vcmpd from crashing when exiting.

700726-1 : Search engine list was updated, and fixing case of multiple entries

Component: Application Security Manager

Symptoms:
Default search engine list does not identify current search engines, and blocks traffic unnecessarily. Part of the issue is that when adding custom search engines, there may be multiple search engines which match the User-Agent header, and this causes the match to fail.

Conditions:
Site accessed by search engines.

Impact:
Traffic from search engines is blocked unnecessarily.

Workaround:
Manually add search engines.

Fix:
Search engine list has been updated to reflect current common search engine usage. Also, this version removes the check of multiple search engines, so that now when multiple Search Engines are matched, the Search Engine bypasses the challenges.

700696-2 : SSID does not cache fragmented Client Certificates correctly via iRule

Component: Local Traffic Manager

Symptoms:
The last few bytes of a very large-sized Client Certificate (typically greater than 16,384 bytes) are not cached correctly if the certificate is received fragmented by the SSL Session ID (SSID) parser.

Conditions:
-- Client Authentication is enabled.
-- A very large Client Certificate is supplied (typically greater than 16,384 bytes).
-- SSL Session ID Persistence is enabled.
-- The iRule CLIENTSSL_CLIENTCERT is enabled.

Impact:
The client certificate is not stored on the BIG-IP device correctly. The last few bytes are missing.

Workaround:
Disable the CLIENTSSL_CLIENTCERT iRule when SSL Session ID (SSID) persistence is in use. Even though the Client Certificate does not get cached, that is preferable to caching an incorrect client certificate.

Fix:
This release supports caching of fragmented client certificates in the SSL Session ID (SSID) persistence feature to properly cache very large-size client certificates (typically exceeding 16,384 bytes).

700571-2 : SIP MR profile, setting incorrect branch param for CANCEL to INVITE

Component: Service Provider

Symptoms:
BIG-IP SIP profile MR does not maintain the Via 'branch parameter' ID when the Via header insertion is enabled for INVITE and CANCEL for the same INVITE.

Conditions:
This happens only when the following conditions are both met:
-- The transport connection that issued INVITE has been terminated.
-- A new transport is used to issue CANCEL

Impact:
The result is different branch IDs for the BIG-IP system-generated Via header. INVITE is only cancelled on the calling side, while on the called side, the line will ring until time out.

Workaround:
None.

Fix:
The branch parameter value calculation now remains consistent throughout the connection.

700564-2 : JavaScript errors shown when debugging a mobile device with ASM deviceID enabled

Component: Application Security Manager

Symptoms:
When debugging a mobile device with ASM Device ID enabled, the Google Chrome browser console log contains JavaScript errors similar to the following: net::ERR_UNKNOWN_URL_SCHEME.

Note: In order to view the Chrome browser console log, you must use BrowserStack from a developer's console, or physically connect the phone by cable, enable 'usb debug',
enable 'device discovery' on Chrome on the desktop, and view the console from there.

Conditions:
-- ASM policy is attached on a virtual server with deviceID enabled.
-- Device ID collection request has been sent from a mobile device.
-- Chrome browser console log is opened.

Impact:
Mobile device app developers might be concerned about the errors, potentially asking about why the ASM JavaScript code attempts to access UNKNOWN_URL_SCHEME in a mobile device.

The errors occur because Device ID enabled on an ASM policy uses the JavaScript request URI argument 'chrome-extension' to detect the existence of malicious browser extension. However, Chrome on Android/iOS does not support 'chrome-extension'.

Workaround:
Disable Device ID in ASM policy.

Fix:
The system now avoids checking Chrome extensions on mobile devices, so no UNKNOWN_URL_SCHEME errors occur.

700556-2 : TMM may crash when processing WebSockets data

Solution Article: K11718033

700527-1 : cmp-hash change can cause repeated iRule DNS-lookup hang

Component: Global Traffic Manager (DNS)

Symptoms:
An iRule that uses RESOLV::lookup can hang repeatedly when cmp-hash configuration is changed.

Conditions:
-- iRule is in the middle of a call to RESOLV::lookup.
-- A change is made to VLAN cmp-hash configuration.

Impact:
The iRule call can hang repeatedly.

Workaround:
Restart the TMM. This will interrupt client traffic while TMM restarts.

Fix:
The iRule connection is reestablished when the pending query expires, so subsequent RESOLV::lookup calls do not hang per TMM.

700433-2 : Memory leak when attaching an LTM policy to a virtual server

Solution Article: K10870739

Component: Local Traffic Manager

Symptoms:
BIG-IP LTM policies may cause an mcpd process memory leak.

As a result of this issue, you may encounter one or more of the following symptoms:

-- Latency when configuring the BIG-IP system.
-- Error messages logged in /var/log/ltm similar to the following example:
01140029:4: HA daemon_heartbeat mcpd fails action is restart.
-- The mcpd process may generate a core file in the /var/core directory.

Conditions:
This issue occurs when all of the following conditions are met:

-- Your configuration includes one or more virtual servers with an associated BIG-IP LTM policy.
-- The BIG-IP LTM policy has at least one rule.
Note: Rules with actions or conditions can leak increased amounts of memory.

-- You delete and add BIG-IP LTM policies that are associated with the virtual server.
Note: This modification causes the memory leak to increase over time.

Impact:
The mcpd process might run slower as memory is consumed, and can fail when all system memory is exhausted. Devices in a high availability (HA) configuration may experience a failover event.

Workaround:
None.

Fix:
The system now prevents MCP from leaking memory when attaching an LTM policy to a virtual server.

700393-2 : Under certain circumstances, a stale HTTP/2 stream can cause a tmm crash

700386-1 : mcpd may dump core on startup

Component: TMOS

Symptoms:
mcpd may generate a core file upon startup, with a message being logged that overdog restarted it because mcpd failed to send a heartbeat for five minutes.

Conditions:
This can happen only at startup.

Impact:
mcpd restarts, but resumes normal operation.

Workaround:
None.

Fix:
mcpd no longer generates a core on startup.

700330 : AJAX blocking page isn't shown when a webpage uses jQuery framework.

Component: Application Security Manager

Symptoms:
Request is blocked by an ASM policy, but the ASM end user does not see the blocking page with a unique support id for the blocked request.

Conditions:
1. ASM policy Asynchronous JavaScript and XML (AJAX) blocking page enabled.
2. ASM policy is working in blocking mode.
3. ASM policy attached to a virtual server.

Fix:
The system now handles Ajax requests being sent via the JQuery framework.

700315-3 : Ctrl+C does not terminate TShark

Solution Article: K26130444

Component: TMOS

Symptoms:
A running TShark process on the BIG-IP system has problems exiting when the user is finished capturing and presses CTRL+C while listening on a tmm VLAN or 0.0.

Conditions:
-- Using TShark on a tmm VLAN or 0.0.
-- Pressing Ctrl+C to exit.

Impact:
TShark does not exit as expected when pressing CTRL+C.

Workaround:
To recover, you can move the process to the background (CTRL+Z) and then halt the process, by running a command similar to the following: kill -9 'pidof tshark'

Fix:
Ctrl+C now terminates TShark as expected.

700143-1 : ASM Request Logs: Cannot delete second 10,000 records of filtered event log messages

Component: Application Security Manager

Symptoms:
Attempting to delete request logs by a filter (10,000 at a time), only works once. Subsequent delete by filter actions do not remove additional earlier logs.

Conditions:
System has over 10,000 ASM request logs by a selected filter, and delete all by filter is used multiple times.

Impact:
Only the latest 10,000 events are deleted.

Workaround:
No work around for deleting by a filter.
Delete all (without filter) works, and deleting selected requests works.

Fix:
Deletion by filter correctly deletes subsequent sets of 10,000 rows per action.

700061-3 : Restarting service MCPD or rebooting BIG-IP device adds 'other' file read permissions to key file

Component: Local Traffic Manager

Symptoms:
Restarting service MCPD or rebooting the BIG-IP device adds Unix 'other' read file permissions for key files.
Key files Unix permission changes from '-rw-r-----' to
'-rw-r--r--'

Conditions:
1. Restarting the service MCPD
2. Rebooting BIG-IP device.

Impact:
Key file Unix read permission changes from '-rw-r-----' to
'-rw-r--r--'

Workaround:
There is no workaround at this time.

Fix:
Fix made sure restart of service MCPD and reboot of device does not change key files Unix read permissions from '-rw-r-----' to
'-rw-r--r--'

700057-3 : LDAP fails to initiate SSL negotiation because client cert and key associated file permissions are not preserved

Component: Local Traffic Manager

Symptoms:
After upgrading to an affected build, the default key will have incorrect group ownership.

Conditions:
Upgrade or load a .ucs with SSL keys configured.

Impact:
File permissions are not preserved in the .ucs file. The httpd process will not be able to use the default key, so anything using it will fail.

Workaround:
Run the following two commands:
tmsh save /sys config
tmsh load /sys config

Fix:
The system now preserves correct permissions for default.key across upgrade and ucs load.

Fix:
The system now handles memory correctly and avoids crashing in this specific scenario.

699598-4 : HTTP/2 requests with large body may result in RST_STREAM with FRAME_SIZE_ERROR

Component: Local Traffic Manager

Symptoms:
HTTP/2 requests with a large body may result in the BIG-IP system sending RST_STREAM with FRAME_SIZE_ERROR.

Conditions:
-- HTTP/2 profile is configured on the virtual server.
-- Request has body size greater than 16 KB.

Impact:

699262-2 : FQDN pool member status remains in 'checking' state after full config sync

Component: Local Traffic Manager

Symptoms:
After performing a full config-sync (with overwrite config option checked) the sync target (peer) shows FQDN pool members stuck in the 'checking' state.

Conditions:
This occurs after a full config sync is forced between peers using FQDN pool members:

tmsh modify cm device-group <dg_name> devices modify { <local_member> { set-sync-leader } }

Impact:
Affected pools show an Availability state of 'unknown', although pool members are available and can pass traffic.

Workaround:
Restart bigd on the affected peer after the config sync.

Fix:
After performing a full config-sync (with overwrite config option checked) the sync target (peer) no longer shows FQDN pool members stuck in the 'checking' state. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

699147 : Hourly billed cloud images are now pre-licensed

696732 : tmm may crash in a compression provider

Solution Article: K54431534

Component: TMOS

Symptoms:
TMM may crash with the following panic message in the log files:

panic: ../codec/compress/compress.c:1161: Assertion "context active" failed.

Conditions:
-- Running on the following platforms: BIG-IP i-series or VIPRION 4400 blades.
-- Virtual servers are performing compression.

Impact:
TMM crashes, Traffic disrupted while tmm restarts.

Workaround:
Do not use compression, or use software compression instead of hardware compression. To configure for software compression, run the following command:

tmsh modify sys db compression.strategy value softwareonly

696468 : Active compression requests can become starved from too many queued requests.

Component: TMOS

Symptoms:
From the "tmctl compress" table: the cur_ctx value for QAT is equal or higher than 512, and the cur_active remains at zero.

CPU utilization per tmm in this condition may be quite high.

Conditions:
At least 512 contexts with no traffic wait in the compression queue and prevent new requests from getting compression service.

Impact:
Compression on a per-tmm basis can stop servicing new requests.

Workaround:
Switch to software compression.

Fix:
Soften the restriction so that accumulated contexts with no traffic cannot not prevent busy contexts from getting compression time.

Fix:
Fixed a BD crash scenario.

696113-1 : Extra IPsec reference added per crypto operation overflows connflow refcount

Component: TMOS

Symptoms:
The size of the refcount field in connflow became smaller, making the length of some crypto queues in IPsec able to reach and exceed the maximum refcount value.

Conditions:
When a large data transfer under an IPsec SA creates a queue of crypto operations longer than the connflow's refcount can handle, the refcount can overflow.

Impact:
Unexpected tmm failover after refcount overflow.

Workaround:
There is no workaround at this time.

Fix:
An object tracking crypto operations now adds a sole reference to the connflow as long as the count of crypto operation pending is nonzero.

696049-3 : High CPU load on generic message if multiple responses arrive while asynchronous Tcl command is running

Component: Service Provider

Symptoms:
High CPU load on generic message if multiple responses arrive while asynchronous Tcl command is running.

Conditions:
Multiple response messages arrive on a connection while an asynchronous Tcl command is running on that connection.

Impact:
High CPU load might occur as multiple responses will be assigned the same request_sequence_number.

Workaround:
None.

Fix:
Request_sequence_numbers are not assigned to response messages until the Tcl event is executed for that message. This avoids assigning the same number to multiple events.

695968-3 : Memory leak in case of a PEM Diameter session going down due to remote end point connectivity issues.

Component: Policy Enforcement Manager

Symptoms:

Conditions:
This occurs when all of the following conditions are met:

-- There is a CMP-disabled virtual server.

-- There is a connection to that server from the control plane of a secondary blade (this can include monitoring traffic).

-- Connections are displayed that include the connection from the secondary blade ('tmsh show sys connection').

Impact:
tmm crashes and restarts impacting traffic.

Workaround:
Do not use 'cmp-enabled no' virtual servers when there will be connections from the BIG-IP control plane to the virtual server.

Avoid using tmsh show sys connection

695901-2 : TMM may crash when processing ProxySSL data

Solution Article: K46940010

695878-5 : Signature enforcement issue on specific requests

Component: Application Security Manager

Symptoms:
Request payload does not get enforced by attack signatures on a certain policy configuration with specific traffic.

Conditions:
-- The violation 'Request exceeds max buffer size' is turned off.

-- The request is longer than the max buffer size (i.e., a request is larger than the internal long_request_buffer_size).

Impact:
Attack signatures are not enforced on the payload of this request at all.

Workaround:
Turn on the violation in blocking 'Request exceed max buffer size'.

Fix:
The operation now looks into part of the payload for the attack signatures enforcement.

695117 : bigd cores and sends corrupted MCP messages with many FQDN nodes

Solution Article: K30081842

Component: Local Traffic Manager

Symptoms:
When configured to monitor large numbers of nodes and/or pool members including FQDN nodes and/or pool members, the following symptoms may occur:
- bigd may core (aborted by sod due to missed heartbeat).
- bigd may produce corrupted MCP messages.
- FQDN nodes and/or pool members may remain in a Checking state indefinitely.

Conditions:
These symptoms may occur on affected versions of BIG-IP when a large number of nodes and/or pool members including FQDN nodes and/or pool members are configured. Depending on the capabilities of the platform in use, approximately one thousand (1,000) or more total nodes and/or pool members may be required to produce these symptoms.

FQDN nodes and/or pool members generate a more significant workload for the bigd daemon than nodes and/or pool members with statically-configured IP addresses. This additional load contributes to high CPU usage and the other observed symptoms.

Impact:
This issue produces the following impacts:
- bigd may core.
- nodes and/or pool members may remain in a Checking state indefinitely.
- bigd may produce corrupted MCP messages, which generate error messages in the LTM log of the following form:

... err mcpd[####]: 01070712:3: Caught configuration exception (0), Can't parse MCP message, ...

Examination of the corrupted MCP message shows objects at the point of corruption that have no hierarchical relationship with the objects referenced at the beginning of the message.

Workaround:
To work around this issue, use the following approaches singly or in combination:
1. Reduce the number of nodes and/or pool members configured for a given BIG-IP system.
2. Configure nodes and/or pool members with statically-configured IP addresses.

Fix:
bigd no longer produces corrupted MCP messages, resulting in nodes and/or pool members remaining in a 'checking' state, with up to 2,000 nodes and/or pool members including FQDN nodes and/or pool members configured. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

694922-4 : ASM Auto-Sync Device Group Does Not Sync

Component: Application Security Manager

Symptoms:

Conditions:
1) ASM sync is enabled on an autosync device group
2) A new ASM entity is created on a device

Impact:
ASM configuration is not correctly synchronized between devices

Workaround:
1) Remove ASM sync from the device group (Under Security ›› Options : Application Security : Synchronization : Application Security Synchronization)
2) Restart asm_config_server.pl on both devices and wait until they come back up
3) Change the device group to a manual sync group
4) On the device with the good configuration re-enable ASM sync for the device group
5) Make a spurious ASM change, and push the configuration.
6) Change the sync type back to automatic

Fix:
Devices no longer spuriously enter an untrusted state

694778-2 : Certain Intel Crypto HW fails to decrypt data if the given output buffer size differs from RSA private key size

Component: Local Traffic Manager

Symptoms:
SSO-enabled Native RDP resources cannot be accessed via hardware (HW) BIG-IP systems with 'Intel Cave Creek' coprocessor (i.e., SSL connection cannot be established with the db variable 'crypto.hwacceleration' enabled, and RSA key used).

Conditions:
The failure might occur in the following scenario:
-- Running on Intel Cave Creek Engine (e.g., BIG-IP 2000 (C112) or 4000 (C113)).
-- Client OS is Mac, iOS, or Android.
-- HW crypto is enabled
-- Using a virtual server with a client SSL profile and 2048 bit RSA key on.
-- Native RDP resource with enabled SSO is used on hardware BIG-IP with 'Intel Cave Creek' coprocessor.
-- Output buffer size differs from RSA private key size.

Impact:
-- SSL connection fails.
-- RDP client cannot launch the requested resource (desktop/application).

Workaround:
There is no workaround other than to disable crypto HW acceleration with following command:
tmsh modify sys db crypto.hwacceleration value disable

Fix:
SSL connection can now be established as expected. SSO-enabled Native RDP resources now can now be accessed via hardware BIG-IP systems with 'Intel Cave Creek' coprocessor (e.g., BIG-IP 2000 (C112) or 4000 (C113) platforms) from Mac, iOS, and Android clients.

694740-1 : BIG-IP reboot during a TMM core results in an incomplete core dump

Component: TMOS

Symptoms:
If an HSB lockup occurs on i10600 and i10800 platforms, then HSB panics and generates a core file for post-analysis. HSB also triggers a nic_failsafe reboot. On this platform, the reboot occurs before the core file is fully written, resulting in a truncated core.

Conditions:
An HSB lockup occurs, triggering a core dump and a nic_failsafe reboot.

Impact:
The reboot happens before the core dump completes, resulting in an incomplete core dump which is not useful for analyzing why the HSB lockup occurred. Traffic disrupted while tmm restarts.

Workaround:
No workaround; does not hinder device operation, but does prevent post-crash analysis.

Fix:
Reboot is delayed until TMM core file is completed.

694717-3 : Potential memory leak and TMM crash due to a PEM iRule command resulting in a remote lookup.

Component: Policy Enforcement Manager

Symptoms:
TMM crashes

Conditions:
PEM iRule command that would result in an inter-TMM lookup on a long lived flow that would result in the PEM iRule command being hit several times. For example, a long lived flow with multiple HTTP transactions.

Impact:
Traffic disrupted while tmm restarts.

Fix:
Always release the connFlow reference associated with the TCL command to avoid a memory leak and potential crash.

-- info clusterd[5705]: 013a0007:6: Checking heartbeat of peer slot: 2 (Last heartbeat 0 seconds ago)

Conditions:
log.clusterd.level set to info.

Impact:
This is a cosmetic issue: clusterd heartbeat messages will be logged at info to the /var/log/ltm.

Workaround:
Set log.clusterd.level to notice.

Fix:
The log level of clusterd logs heartbeat check messages has changed. For 'Skipping heartbeat check' messages, the log level is now debug, and 'Checking heartbeat of peer slot' messages log level is verbose and now reports on which bp the heartbeat was received.

694696-3 : On multiblade Viprion, creating a new traffic-group causes the device to go Offline

Component: TMOS

Symptoms:
All devices in the failover device group will go offline, resulting in traffic disruption and possible failovers.

Conditions:
When a new traffic-group is created on a multiblade Viprion system that is a member of a sync-failover device group.

Impact:
Traffic to all other traffic-groups is disrupted for several seconds.

Workaround:
There is no workaround at this time.

Fix:
Creating a new traffic-group does not disrupt existing traffic-groups.

694656-3 : Routing changes may cause TMM to restart

Solution Article: K05186205

Component: Local Traffic Manager

Symptoms:
When routing changes are made while traffic is passing through the BIG-IP system, TMM might restart. This isn't a general issue, but can occur when other functionality is in use (such as Firewall NAT).

Conditions:
-- Routing changes occurring while BIG-IP is active and passing traffic.

-- Dynamic routing, due to its nature, is likely increase the potential for the issue to occur.

-- Usage of Firewall NAT functionality is one specific case known to contribute to the issue (there may be others).

Impact:
TMM restarts, resulting in a failover and/or traffic outage.

Workaround:
If dynamic routing is not in use, avoiding static route changes may avoid the issue.

If dynamic routing is in use, there is no workaround.

Fix:
TMM now properly manages routing information for active connections.

694319-3 : CCA without a request type AVP cannot be tracked in PEM.

Component: Policy Enforcement Manager

Symptoms:
May cause diagnostic issues as not all CCA messages cannot be tracked.

Conditions:
1. PEM with Gx/Gy configured
2. PCRF sends CCA's without a request type AVP

Impact:
May hamper effective diagnostics.

Workaround:
Mitigation:
Configure the PCRF to always include a request type in its CCAs.

Fix:
Add a statistics counter to track CCA's that do not request type AVPs.
Name of new counter:cca_unknown_type

694318-3 : PEM subscriber sessions will not be deleted if a CCA-t contains a DIAMETER_TOO_BUSY return code and no request type AVP.

Component: Policy Enforcement Manager

Symptoms:
Subscriber sessions in PEM will be stuck in a "Marked for Delete" state.

Conditions:
1. PEM provisioned with Gx.
2. PCRF responds to a CCR-t with a DIAMETER_TOO_BUSY return code and no Request type AVP.

Impact:
Subscriber sessions stuck in delete pending resulting in a potential increase in memry consumption over a period of time.

Workaround:
Mitigation:
PCRF (remote Diameter end point) must send a CCA-t with a request type AVP in case a DIAMETER_TOO_BUSY return code is present.

Fix:
Handle the DIAMETER_TOO_BUSY return code on a CCA-t regardless of the request type AVP.

694274-2 : [RHSA-2017:3195-01] Important: httpd security update - EL6.7

Solution Article: K23565223

694073-1 : All signature update details are shown in 'View update history from previous BIG-IP versions' popup

Component: Application Security Manager

Symptoms:
If you are running a BIG-IP release named with 4 digits (e.g., 12.1.3.1), all signature update details are shown only in 'View update history from previous BIG-IP versions' popup. The 'Latest update details' section is missing.

Conditions:
Running a BIG-IP software release named with 4 digits (e.g., 12.1.3.1).

Impact:
Low and incorrect visibility of signature update details.

Workaround:
Signature update details can be viewed in 'View update history from previous BIG-IP versions' popup.

Fix:
Signature updates are now shown correctly for all versions.

693996-3 : MCPD sync errors and restart after multiple modifications to file object in chassis

Solution Article: K42285625

Component: TMOS

Symptoms:
Upon modifying file objects on a VIPRION chassis and synchronizing those changes to another VIPRION chassis in a device sync group, the following symptoms may occur:

1. Errors are logged to /var/log/ltm similar to the following:

-- err mcpd[<#>]: 0107134b:3: (rsync: link_stat "/config/filestore/.snapshots_d/<_additional_path_to/_affected_file_object_>" (in csync) failed: No such file or directory (2) ) errno(0) errstr().
-- err mcpd[<#>]: 0107134b:3: (rsync error: some files could not be transferred (code 23) at main.c(1298) [receiver=2.6.8] syncer /usr/bin/rsync failed! (5888) () Couldn't rsync files for mcpd. ) errno(0) errstr().
-- err mcpd[<#>]: 0107134b:3: (rsync process failed.) errno(255) errstr().
-- err mcpd[<#>]: 01070712:3: Caught configuration exception (0), Failed to sync files..

2. MCPD may restart on a secondary blade in a VIPRION chassis that is receiving the configuration sync from the chassis where the file object changes were made.

Conditions:
Making multiple changes to the same file objects on a VIPRION chassis and synchronizing those changes to another VIPRION chassis in a device sync group.

Impact:
Temporary loss of functionality, including interruption in traffic, on one or more secondary blades in one or more VIPRION chassis that are receiving the configuration sync.

Workaround:
After performing one set of file-object modifications and synchronizing those changes to the high availability (HA) group members, wait for one or more minutes to allow all changes to be synchronized to all blades in all member chassis before making and synchronizing changes to the same file-objects.

693910-2 : Traffic Interruption for MAC Addresses Learned on Interfaces that Enter Blocked STP State (2000/4000/i2800/i4800 series)

Component: Local Traffic Manager

Symptoms:
Some MAC addresses might experience delayed forwarding after the interface on which they are learned transition to a STP blocked state. This is because the FDB entries are not being flushed on these interfaces after they change to a block state. Traffic destined to these MAC addresses gets dropped until their associated entries in the FDB age out.

Conditions:
MAC addresses are learned on a STP forwarding interface that transitions to a blocked interface following a topology change.

Impact:
Traffic interruption for up to a few minutes for MAC addresses learned on the affected interface.

Workaround:
None.

Fix:
FDB entries are now flushed by interface whenever an interface transitions to a STP block state.

693884-3 : ospfd core on secondary blade during network unstability

Component: TMOS

Symptoms:
ospfd core on secondary blade while network is unstable.

Conditions:
-- Dynamic routing configured with OSPF on a chassis.
-- During a period of network instability.

Impact:
Dynamic routing process ospfd core on secondary blade.

Workaround:
None.

693838 : Adaptive monitor feature does not mark pool member down when hard limit set on UDP monitors

Component: Local Traffic Manager

Symptoms:
Member of pool is not marked down when response time exceeds hard limit.

Conditions:
Adaptive monitoring enabled for UDP monitor and server response time exceeds hard limit.

Impact:
Member remains in pool despite exceeding hard limit which may result in degraded services.

Workaround:
None.

693744-3 : CVE-2018-5531: vCMP vulnerability

Solution Article: K64721111

693739-3 : VPN cannot be established on macOS High Sierra 10.13.1 if full tunneling configuration is enabled

Component: Access Policy Manager

Symptoms:
For some Network Access configurations, VPN cannot establish a connection with client systems running macOS High Sierra 10.13.1 using F5 Edge client or Browser helper apps.

Conditions:
The following conditions must be true:
-- The Network Access resource Traffic Options setting is configured for Force all Traffic Through Tunnel.
-- The Network Access resource Allow Local Subnet setting is disabled.
(Both of these options are defaults.)
-- Client running macOS High Sierra 10.13.1.

Impact:
The Edge Client unsuccessfully tries to connect, resulting in a loop. The client cannot establish VPN.

Workaround:
1. Navigate to the Network Access resource.
2. Set the Network Access resource Allow Local Subnet checkbox to Enabled.
3. Save the setting, and apply the Access Policy.

Fix:
Edge Client operation does not go into a reconnect loop and is able to establish and maintain connection successfully on macOS High Sierra 10.13.1.

693582-3 : Monitor node log not rotated for certain monitor types

Component: Local Traffic Manager

Symptoms:
When Monitor Logging is enabled for an LTM node or pool member using certain monitor types, the monitor node log under /var/log/monitors/ is not rotated or compressed when log rotation occurs.

Conditions:
This occurs if Monitor Logging is enabled for an LTM node or pool member, and the LTM node or pool member uses any of the following monitor types:
- icmp
- gateway-icmp
- external

Impact:
Depending on the affected BIG-IP version in use, effects may include the following symptoms:

1. The active monitor node log is not rotated (not renamed from *.log to *.log.1).

2. The active monitor node log is rotated (renamed from *.log to *.log.1), but subsequent messages are logged to the rotated log file (*.log.1) instead of to the 'current' log file name (*.log).

3. The active monitor node log is not compressed (*.log.2.gz) when log rotation occurs.

Workaround:
To allow logging to the correct monitor node log file to occur, and for rotated monitor node log files to be compressed, disable Monitor Logging for the affected node or pool member(s).

-- If symptom #1 occurs, Monitor Logging can be re-enabled after log rotation has occurred.

-- To address symptoms #2 or #3, Monitor Logging can be re-enabled immediately.

For more information on Monitor Logging, see:
K12531: Troubleshooting health monitors :: https://support.f5.com/csp/article/K12531.

Fix:
Monitor node logs are now rotated/compressed as expected.

693388-1 : Log additional HSB registers when device becomes unresponsive

Component: TMOS

Symptoms:
HSB becomes unresponsive, and logs no registers to indicate the state of the device. There is no logging of additional registers to assist in diagnosing the failure.

Conditions:
It is unknown under what conditions the HSB becomes unresponsive.

Impact:
Limited visibility into the HSB state when it becomes unresponsive.

Workaround:
None.

Fix:
There is now logging of additional registers to assist in diagnosing the failure.

The registers can be seen in the TMM log files when there is either an HSB transmitter or receive failure.

693312-2 : vCMPd may crash when processing bridged network traffic

Solution Article: K03165684

693308-3 : SSL Session Persistence hangs upon receipt of fragmented Client Certificate Chain

Component: Local Traffic Manager

Symptoms:
When a very large Client Certificate Chain, typically exceeding 16,384 bytes, is received by BIG-IP on a virtual service, and Session Persistence is enabled, the handshake hangs.

Conditions:
[1] SSL client authentication is enabled on the backend server
[2] No SSL profile is specified on the BIG-IP device for the virtual service, on both, client and server side
[3] An SSL connection is initiated from the front-end client, via the BIG-IP's virtual service, to the backend server.
[4] The client certificate chain is passed to the BIG-IP device as part of initiating the connection.

Impact:
The backend server will not be securely accessible via SSL because the connection hangs

Workaround:
Disable SSL Session Persistence.

Fix:
Whenever a fragmented message is received by a BIG-IP virtual service, subsequent messages contain a 5-byte header, each, which should be accounted for. Upon taking this into consideration, no more multiple-of-5 bytes are found missing while the message is being parsed by the Session Persistence parser, and the parser no longer hangs.

693211-3 : CVE-2017-6168

Solution Article: K21905460

693106-2 : IKEv1 newest established phase-one SAs should be found first in a search

Component: TMOS

Symptoms:
Some IKEv1 implementations might delete "duplicate" phase one IKE SAs, even though not yet expired, keeping only the most recently negotiated IKE-SA. If this happens, and BIG-IP uses an older SA to negotiate, then phase two negotiation can fail.

If at all possible, we want BIG-IP to prefer the newest SA for a given remote peer. If a peer deletes a second SA without notifying BigIP, preferring a newest SA may mitigate the problem.

Conditions:
The situation seems mostly easily arranged when two peers initiate a new IKE-SA at the same time, so that both are negotiated concurrently, since neither has yet been established. Afterward, there are two IKE-SAs for one remote peer, nearly the same age.

If the other end deletes a duplicate without sending a DELETE message to BigIP, we might accidently use the older SA of a pair.

Impact:
If BIG-IP picks a mature IKE-SA for phase two negotiation that has been deleted by a peer, then BIG-IP's attempt to negotiate a new phase two SA will fail.

Workaround:
Try to configure other IPsec implementations to avoid deleting duplicate IKE-SAs.

Fix:
At the momenet a new IKE-SA is established, we now move that SA to the head of the hashmap bucket searched for that remote peer in the future. This makes us more likely to use the newest SA from the perspective of a remote peer, the next time we initiate another phase two negotiation ourselves.

693007-3 : Modify b.root-servers.net IPv4 address 192.228.79.201 to 199.9.14.201 according to InterNIC

Component: Global Traffic Manager (DNS)

Symptoms:
The current IPv4 address for b.root-servers.net is 192.228.79.201. The IPv4 address for b.root-servers.net will be renumbered to 199.9.14.201, effective 2017-10-24. The older number will be invalid after that date.

Conditions:
Several profiles contain the b.root-servers.net IPv4 address as 192.228.79.201.

Impact:
The impact is likely minimal, at most a single timeout for pending TLD queries when they happen to round-robin onto an old IP address, probably not more often than the hint's TTL, which is more than a month, and even this should cause a timeout only when the old IP actually stops responding.

Workaround:
Update the root hints for all affected profiles manually except the hardwired ones.

Fix:
The IPv4 address for b.root-servers.net has been renumbered to 199.9.14.201, effective 2017-10-24.

Behavior Change:
The IPv4 address for b.root-servers.net has been renumbered to 199.9.14.201, effective 2017-10-24, according to InterNIC. The old IPv4 address (192.228.79.201) will continue to answer queries for at least 6 months.

692970-3 : Using UDP port 67 for purposes other than DHCP might cause TMM to crash

Component: Local Traffic Manager

Symptoms:
DHCP relay presumes that a flow found via lookup is always a server-side flow of type DHCP relay. Hence TMM can crash when DHCP relay makes a server connection if UDP port 67 is used for another purpose, in which case a wrong DHCP server flow could be selected.

Conditions:
A UDP port 67 is configured for a purpose other than DHCP relay.

Impact:
TMM restart causes traffic interruption or failover.

Workaround:
Do not use UDP port 67 for other virtual servers, or configure a drop listener on certain VLANs that cannot avoid using UDP port 67.

Fix:
TMM no longer crashes with DHCP flow validation.

692941-3 : GTMD and TMM SIGSEGV when changing wide IP pool in GTMD

Component: Global Traffic Manager (DNS)

Symptoms:
Changing wide IP causes gtmd and tmm core under certain conditions.

Conditions:
-- GTM pool is removed when it is referenced by a persist record.
-- That record is accessed before it is purged.

Impact:
gtmd and/or tmm core. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
Changing wide IP no longer causes gtmd and tmm core when GTM pool is removed when it is referenced by a persist record, and that record is accessed before it is purged.

692307-1 : User with 'operator' role may not be able to view some session variables

Component: Access Policy Manager

Symptoms:
When a user with 'operator' role tries to view the session variables, the GUI may show the following error: An error has occurred while trying to process you request.

Conditions:
This occurs when there is a huge blob of data associated with the user whose session variable is being viewed. For example Active Directory (AD) user accounts with thumbnailphoto and userCertificate user attributes containing binary data.

Impact:
User cannot view the session variables for those particular sessions. This data is available, however, via clicking on the Session ID.

Workaround:
Find this data via clicking on the session ID.

Fix:
User with 'operator' role can now view all expected session variables

692239-1 : AOM menu power off then on results in 'Host Power Cycle Event' SEL log entries posted every two seconds

Solution Article: K31554905

Component: TMOS

Symptoms:
When using the AOM menu, LCD touchscreen, or the operating system 'halt' command to power off then on the host CPU on i5600, i5800, i7600, i7800, i10600, i10800 platforms, the AOM creates a 'Host Power Cycle Event' SEL log entry every two seconds. The SEL log will continue to grow until external power to the appliance is fully power cycled.

Conditions:
-- Running on i5600, i5800, i7600, i7800, i10600, i10800 platforms.

-- With an older version of CPLD code installed (e.g., CPLD 0x45), power-off the host using the AOM menu, the LCD touchscreen, or the operating system's 'halt' command.

   + Bring up the AOM menu using ESC shift-9, then select 'p' and '0' from the menu to power off the host CPU complex.
   + On the LCD touchscreen, navigate to [System] menu and select [Power Off] to power off the host CPU complex.
   + Run the 'halt' command on the BIG-IP host subsystem.

-- Wait a few seconds, and power on the host.

   + On the AOM menu, select 'p' and '1' to power on the host CPU complex.
   + On the LCD touchscreen, navigate to [System] menu and select [Power On] to power on the host CPU complex.
   + There is no equivalent shell method to turn the power back on after running the 'halt' command.

Impact:
This results in ongoing 'Host Power Cycle Event' messages to post in the SEL log (tail /var/log/sel) every two seconds.

The SEL log will continue to grow and wrap as this message continues to post to the SEL log every two seconds.

This results in a very large number of SEL entry fetches by the host CPU to the AOM and can place a substantial load on the AOM interface.

Workaround:
The actual fix is to install a newer version of i5600, i5800, i7600, i7800, i10600, i10800 platform CPLD code (e.g., CPLD 0x54 or CPLD 0x55).

Another workaround is to fully power cycle the appliance.
However, every time the AOM menu is used to power off then on the host, the SEL log entries re-appear.

Fix:
This issue is fixed in newer versions of the i5600, i5800, i7600, i7800, i10600, i10800 platforms CPLD (e.g., CPLD 0x54 or CPLD 0x55).

692189-3 : errdefsd fails to generate a core file on request.

Component: TMOS

Symptoms:
Should errdefsd crash or be manually cored for the purpose of gathering diagnostic information, no core file will be generated.

Conditions:
Forcing errdefsd to core for diagnostic purposes.

Impact:
Increased communication required with F5 Support when attempting to diagnose problems with errdefsd.

Workaround:
1. Add the following lines to the official errdefsd script, /etc/bigstart/scripts/errdefsd:
16a17,19
> # set resource limits, affinity, etc
> setproperties ${service}
>
2. Run the following command: bigstart restart errdefsd

Fix:
errdefsd now generates a core file when forced to core.

692179-3 : Potential high memory usage from errdefsd.

Component: TMOS

Symptoms:
errdefsd memory usage grows with each config-sync or config update.

Conditions:
Ever increasing errdefsd memory usage is visible when the following conditions are met:
-- Config updates are frequent.
-- management-port logging is not being used.

Impact:
In extreme cases, errdefsd memory usage might increase userland memory-pressure. Note, however, that it isn't actually using the extra memory, so while Virtual Memory Size (VSZ) might be high, Resident Set Size (RSS) need not be.

Workaround:
A workaround for this problem is to periodically send logs to a management-port destination. The destination may be as simple as a dummy UDP port on 127.0.0.1. Adding such a destination to the publisher for an existing, active log source will work. errdefsd just needs a reason to process and flush accumulating configurations.

Fix:
The changes in this bug force errdefsd to check for config changes once every second in addition to checking whenever management-port destination logs come in.

692165-2 : A request-log profile may not log anything for the $VIRTUAL_POOL_NAME token

Component: TMOS

Symptoms:
For some HTTP requests, a request-log profile can log nothing for the $VIRTUAL_POOL_NAME token (which expands to an empty string in the resulting logs).

Conditions:
- The virtual server where the request-log profile is used also uses OneConnect.

- The client uses HTTP Keep-Alive and sends multiple HTTP requests over the same TCP connection.

Impact:
For all HTTP requests the client sends except the first one, the $VIRTUAL_POOL_NAME token logs nothing. As a result, a BIG-IP Administrator may struggle to determine which pool serviced which request.

Workaround:
The $SERVER_IP and $SERVER_PORT tokens work for all requests, and so if those are also being logged it may be possible to deduce the pool name from that information.

However, there is no workaround to make the $VIRTUAL_POOL_NAME token work all of the time.

692158-2 : iCall and CLI script memory leak when saving configuration

Component: TMOS

Symptoms:
Whenever an iCall script or CLI script saves the configuration, the scriptd process on the device leaks memory.

Conditions:
Use of iCall or CLI scripts to save the configuration.

Impact:
Repeated invocation might cause the system to run out of memory eventually, causing tmm to restart and disrupting traffic.

Workaround:
There is no workaround other than not saving the configuration from iCall or CLI scripts.

Fix:
scriptd process on the device no longer leaks memory when iCall and CLI scripts are used to save the configuration.

692123-2 : GET parameter is grayed out if MobileSafe is not licensed

Component: Fraud Protection Services

Symptoms:
GET parameter is grayed out if MobileSafe is not licensed.

Conditions:
-- Provision FPS on a system whose license has at least one active feature.
-- Do not license MobileSafe.

Impact:
In FPS Parameter's list, the GET method is always grayed out.

Workaround:
Use either of the following workarounds:
-- License MobileSafe.
-- Use TMSH or REST.

Fix:
The GET method is not grayed out if MobileSafe is not licensed.

692095-3 : bigd logs monitor status unknown for FQDN Node/Pool Member

Solution Article: K65311501

Component: Local Traffic Manager

Symptoms:
While monitoring FQDN nodes or pool members, bigd may log the current or previous monitor status of the node or pool member as 'unknown' in messages where that state internally could have been logged as 'checking' or 'no address' for FQDN template nodes. Other states for FQDN configured nodes or pool members log monitor status as expected. Messages are similar to the following:

notice bigd[####]: 01060141:5: Node /Common/node_name monitor status unknown [ ip.address: unknown ] [ was up for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: unknown ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: up ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status unknown. [ ] [ was unchecked for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status up. [ ] [ was unknown for ##hrs:##mins:##sec ]

Conditions:
This may occur of the FQDN template node or pool member is in a 'checking' or 'no address' state.
The 'checking' state may occur if the DNS resolution of the FQDN node or pool member name is in progress.
The 'no address' state may occur if no IP addresses were returned by the DNS server for the configured FQDN node or pool member name.

Impact:
Unable to triage state of FQDN nodes or pool members identified in these log messages, to determine whether further troubleshooting is required, or what specific problem condition might require further investigation.

Workaround:
None.

Fix:
An FQDN-configured node or pool member logs each internal monitor status, including for scenarios of 'checking' and 'no address' for FQDN template nodes which were previously logged as 'unknown'.

691945-2 : Security Policy Configuration Changes When Disabling Learning

Component: Application Security Manager

Symptoms:
When Learning is enabled in either manual or automatic mode, and is then disabled. This was considered to be the end of the learning process, and so changes are automatically made to the default wildcard entities ("*" URL, Parameter, Filetype) such as removing the element from staging.

The user is not notified of these changes, and they may not be expected, leading to undesired security enforcement.

Conditions:
-- Learning is enabled in Manual or Automatic mode.
-- Learning is then disabled.

Impact:
Unexpected changes to the default wildcard elements in the policy can lead to undesired security enforcement.

Workaround:
The audit log shows all changes that were made to the policy, and undesired changes can be remedied before the policy changes are applied.

Fix:
No changes are made to the default wildcard entities upon disabling of learning.

691897-1 : Names of the modified cookies do not appear in the event log
