Cumulative fix details for BIG-IP v11.5.8 that are included in this release

750488-1 : 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.

750484-1 : 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:

750472-1 : Certain BIG-IP DNS configurations improperly respond to DNS queries that contain EDNS OPT Records

Component: Global Traffic Manager (DNS)

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

Workaround:
None.

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

Note: The EDNS Compliance Tester should produce output similar to the following when run against DNS Express:

example1.com. @10.10.10.125 (ns.example1.com.): dns=ok edns=ok edns1=ok edns@512=ok ednsopt=ok edns1opt=ok do=ok ednsflags=ok optlist=ok signed=ok ednstcp=ok

749774-6 : 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.

---

749675-6 : 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.

723130-4 : 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:
The expired OVA signing certificate has been replaced with a valid signing certificate.

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

---

721895-3 : 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.

716922-6 : 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.

713951-1 : tmm core files produced by nitrox_diag may be missing data

Component: Local Traffic Manager

Symptoms:
When the nitrox_diag utility generates a tmm core file, that file might include data for only one tmm thread instead of all tmm threads.

Conditions:
-- Running the nitrox_diag utility.
-- Using devices with the Cavium Nitrox crypto card.
-- The nitrox_diag utility generates a tmm core file.

Impact:
The resulting core file might include data for only one tmm thread instead of all tmm threads, making it more difficult for F5 to diagnose reported problems with the Cavium Nitrox crypto card. Traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

Fix:
When the nitrox_diag utility generates a tmm core file, that file now includes data for all tmm threads instead of only one.

---

711281-1 : 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.

708249-6 : 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.

707226-4 : 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.

706304-1 : ASU and other Update Check services overload F5 download server

Component: Application Security Manager

Symptoms:
ASM Signature Update (ASU) and other Update Check services may fail due to an overload on the F5 download server.

Conditions:
-- Automatic update attempt is initiated during specified schedule.
-- F5 download server is overloaded by Update attempts.

Impact:
ASU and other Update Check services fail.

Workaround:
To work around this issue, run manual updates instead.

To prevent this issue, change the time of the daily job run. To do so, follow these steps:

1. Open the cron job text file.
   # vi /etc/crontab

2. Change this line as follows:
   From: 02 4 * * * root run-parts /etc/cron.daily
   To: 10 4 * * * root run-parts /etc/cron.daily

3. Save the changes, and quit vi.

This will change the automatic updates to run at 4:10 rather than 4:02.

Fix:
ASU and other Update Check services now stagger download attempts to prevent F5 download server overload.

702490-6 : 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.

696049-5 : 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.

695878-1 : 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.

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:

689826-4 : Proxy/PAC file generated during VPN tunnel is not updated for Windows 10 (unicode languages like: Japanese/Korean/Chinese)

Solution Article: K95422068

Component: Access Policy Manager

Symptoms:
On a Microsoft Windows 10 system configured for a Unicode language (Japanese, Korean, or Chinese, for example) the client proxy autoconfig file is not assigned in the Microsoft Internet Explorer browser after the VPN connection is established.

Conditions:
- Client proxy settings provided in Network Access settings, or client is configured with proxy prior to establishing VPN tunnel.
- Windows 10 configured for a unicode-language (Japanese/Korean/Chinese/etc.).
- VPN tunnel is established using either a browser or the Edge Client.

Impact:
Proxy settings are not applied on client side after VPN is established.

Workaround:
There are two possible workarounds:
Workaround A
============
-- Change the language to English from Control panel :: Region :: Administrative :: Language for non-Unicode programs :: Change System locale.
 
Workaround B
============
-- Add a variable assign agent in the access policy, after the logon item and before the resource is assigned. To do so, follow this procedure:

 1. Set the custom variable name to the following value:
    config.connectivity_resource_network_access./Common/<network_access_resource_name>.client.ConnectionTrayIcon
    Note: <network access resource name> is the name of the network access resource.

 2. Set the value to be of the type 'custom expression' and populate it with the following value (including the quotation marks):
    return "</ConnectionTrayIcon><connection_name_txt>F5VPN</connection_name_txt><ConnectionTrayIcon>"
    Note: The <connection_name_txt> tag contains the name of the adapter that the client will create.

 3. After making these two changes, apply the access policy. The next time the VPN is established, a new virtual adapter entry will be created with the name provided in <connection_name_txt> tag.

Fix:
Previously, on a Windows 10 system configured for a Unicode language (for example, Japanese, Korean, or Chinese) the client proxy autoconfig file was not assigned with Internet Explorer after the VPN connection was established. This issue has been fixed.

672988-4 : MCP memory leak when performing incremental ConfigSync

Solution Article: K03433341

Component: TMOS

Symptoms:
MCP will leak memory when performing incremental ConfigSync operations to peers in its device group. The memory leak can be seen tmctl utility to watch the umem_alloc_80 cache over time.

This leak occurs on the device that is sending the configuration.

Conditions:
A device group that has incremental sync enabled. In versions prior to BIG-IP v13.0.0, this is controlled by the 'Full Sync' checkbox. When unchecked, the system attempts to perform incremental sync operations.

Impact:
MCP leaks a small amount of memory during each sync operation, and after an extended period of time, might eventually crash.

Workaround:
None.

Fix:
MCPD no longer leaks when performing incremental ConfigSync operations.

---

672480-1 : WebSSO plugin process may become unresponsive in rare situations for Kerberos SSO

Component: Access Policy Manager

Symptoms:
HTTP requests that are being processed by Kerberos SSO never leaves APM, and connections simply time out.

Conditions:
There is an issue in MIT krb5 library for calculating wait time for responses from KDC, which ends up with a negative value. This translates to infinite timeout by poll() syscall. At the same time, if all Kerberos requests to KDC are dropped (e.g., by a misconfigured firewall), Kerberos SSO never receives the responses, and Kerberos SSO never gives up on waiting for the KDC response (this is an issue in the library).

Impact:
A deadlock occurs within the Kerberos SSO. Eventually there will be a global deadlock, which causes this particular WebSSO process to be completely unresponsive for Kerberos SSO functionality. APM end users cannot access the backend.

Workaround:
For this issue to have a real impact, there must be an unresponded-to Kerberos request. To eliminate this possibility, make sure there is no firewall blockage, incorrect routing, etc., so that WebSSO always receives responses, even negative ones.

Note: WebSSO will never use infinite timeout when waiting for Kerberos responses, so even if a firewall blocks the Kerberos request, although Kerberos SSO does not function, it does not cause global unresponsiveness from the WebSSO process.

667278-6 : DSC connections between BIG-IP units may fail to establish

Component: TMOS

Symptoms:
The device service clustering (DSC) connection between two BIG-IP units may fail to establish. One unit will log messages similar to the following example:

-- err mcpd[7912]: 01071af4:3: Inbound CMI connection from IP (192.168.100.1) denied because it came from VLAN (v1542), not from expected VLAN (tmm).

While the unit at the other end of the connection will log messages similar to the following example:

-- notice mcpd[5730]: 01071432:5: CMI peer connection established to 192.168.200.1 port 6699 after 0 retries
May 31 20:58:04 BIG-IP-c-sea notice mcpd[5730]: 0107143c:5: Connection to CMI peer 192.168.200.1 has been removed

Conditions:
This issue occurs when the Self-IP addresses used for Config-Sync by the two BIG-IP units are not in the same IP subnet, and special routing is configured between the BIG-IP units. Examples of special routing include a gateway pool or dynamic routing configurations with multiple routes to the same destination (i.e., ECMP routing).

Impact:
Config-Sync and device discovery operations will fail between affected units.

Workaround:
You can work around this issue by using Self-IP addresses for Config-Sync that are on the same IP subnet or rely on simpler routing to achieve connectivity (i.e., a single route).

Fix:
Config-Sync and device discovery operations no longer fail.

Solution Article: K20228504

Component: Local Traffic Manager

Symptoms:
In some cases, a mirrored FastL4 virtual server may fail to forward the SYN on the server-side after receiving the context-ack from the peer. Note: This is a connection-failure through the active system, not simply a failure to mirror to the peer.

Symptoms include:
-- TCP connection failures.
-- Possibly other packets lost.

Conditions:
-- FastL4 virtual server.
-- Mirroring is enabled.
-- Certain traffic interleaving might be necessary for this intermittent problem to occur.

656902 : Upgrade to 11.5.4 HF3 may remove valid cipher suite configuration from SSL profile

Component: Local Traffic Manager

Symptoms:
During the upgrade to 11.5.4 HF3, the upgrade will remove the DHE-DSS from cipher suite, which will cause the cipher suites configured beginning with the characters '@', '+', '-', or '!' will be removed from the configuration.

Conditions:
clientssl/serverssl profile ciphers configuration contains keywords beginning with the characters '@', '+', '-', or '!'.

Impact:
Cipher suites are configured using keywords such as AES, AES-GCM, !DES, -ADH, @STRENGTH, etc. The issue causes keywords beginning with the characters '@', '+', '-', or '!' to be removed from the configuration.

For example, if the cipher suite configuration before installing 11.5.4 HF3 was: 'NATIVE:!SSLV2:!SSLV3:!MD5:!EXPORT:!LOW:ECDHE+AES-GCM:ECDHE+AES:DHE+AES-GCM:DHE+AES:AES-GCM+RSA:RSA+AES:RSA+3DES:!RC4:!ADH:!ECDHE_ECDSA:!ECDH_ECDSA:!ECDH_RSA:!DHE-RSA-DES-CBC3-SHA:!ECDHE-RSA-DES-CBC3-SHA:!DHE-RSA-AES128-SHA:+DES-CBC3-SHA'

After installing 11.5.4 HF3 it would be reduced to: 'NATIVE:ECDHE+AES-GCM:ECDHE+AES:DHE+AES-GCM:DHE+AES:AES-GCM+RSA:RSA+AES:RSA+3DES'

Workaround:
Manually restore the clientssl/serverssl profile cipher configuration.

Fix:
Fixed an issue that causes the cipher suites configured beginning with the characters '@', '+', '-', or '!' to be removed from the configuration on upgrade.

655649-5 : BGP last update timer incorrectly resets to 0

Solution Article: K88627152

Component: TMOS

Symptoms:
In ZebOS, every time the scan timer resets it also incorrectly resets the BGP last update timer as shown under the imish command 'sh ip route'.

Output from 'sh ip route':

4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro
...
B 10.30.0.0/16 [20/0] via 10.10.1.2, eno33554952, 00:00:32
               [20/0] via 10.10.1.6, eno33554952, 00:00:32
...
4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro

4054fdc0-3e51-4079-b52f-4a3b058a3f93#sh ip ro
...
B 10.30.0.0/16 [20/0] via 10.10.1.2, eno33554952, 00:00:00 <<<< shouldn't reset
               [20/0] via 10.10.1.6, eno33554952, 00:00:00

Conditions:
Once ZebOS has learned a route from a BGP peer the route will show up under 'sh ip route' and the BGP last update timer will incorrectly reset.

Impact:
If BGP routes are being redistributed into other protocols, the route may flap in the destination process.

Workaround:
None.

Fix:
BIG-IP no longer resets the last update time of learned routes via BGP and BGP routes redistributed into other protocols no longer flap.

654599-3 : The GSLB Pool Member Manage page can cause Tomcat to drop the request when the Finished button is pressed

Solution Article: K74132601

Component: Global Traffic Manager (DNS)

Symptoms:
Tomcat can potentially drop requests made by the client via the Web GUI on the GSLB Pool Members Manage page.

Conditions:
The config contains a large amount (in the thousands) of GSLB virtual servers or wide IP's, resulting in the action not being completed.

Impact:
The "Finished" button on that page does not save the changes made on that page.

Workaround:
Use TMSH.

Fix:
Fixed an issue with saving GSLB data via the GUI in large configurations.

651772-6 : IPv6 host traffic may use incorrect IPv6 and MAC address after route updates

Component: Local Traffic Manager

Symptoms:
IPv6 traffic generated from the host, either from a host daemon, monitors, or from the command line, may use an MAC and IPv6 source address from a different VLAN.

Conditions:
- Multiple vlans with IPv6 configured addresses.
- Multiple routes to the same destination, either the same or more specific, default routes, etc. that cover the traffic destination.
- Changes in routes that will cause the traffic to the destination to shift from one vlan and gateway to another. This can be typically observed with dynamic routing updates.

Impact:
Traffic to the destination may fail due to using incorrect source IPv6/MAC address.
This may cause monitor traffic to fail.

Workaround:
Continuous traffic to the IPv6 link-local nexthops can avoid this issue.
This may be achieved by a script or an external monitor pinging the nexthop link-local address using the specific vlan.

Fix:
IPv6 host traffic no longer use incorrect IPv6 and MAC address after route updates.

Behavior Change:
Introduction of sys db ipv6.host.router_probe_interval, to control sysctl net.ipv6.conf.default.router_probe_interval value. This value is default to 5s.

649933-5 : Fragmented RADIUS messages may be dropped

Component: Service Provider

Symptoms:
Large RADIUS messages may be dropped when processed by iRules.

Conditions:
This occurs when a RADIUS message that exceeds 2048 bytes is processed by an iRule containing the RADIUS::avp command.

Impact:
The RADIUS message will be dropped, and an error will be logged that resembles:

Illegal argument (line 1) (line 1) invoked from within "RADIUS::avp 61 "integer""

Workaround:
Remove RADIUS::avp commands from iRules processing large messages, or ensure that no RADIUS client or server will send large messages.

646643-4 : HA standby virtual server with non-default lasthop settings may crash.

Solution Article: K43005132

Component: Local Traffic Manager

Symptoms:
A long-running high availability (HA) Standby Virtual Server with non-default lasthop settings may crash TMM.

Conditions:
-- HA standby virtual server is configured on the system with non-default lasthop configurations (e.g., lasthop pools or autolasthop disabled, etc).

-- That virtual server receives more than 2 billion connections (2 billion is the maximum value of a 32-bit integer).

Impact:
TMM on the next-active device crashes. The Active device is not affected. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
HA standby virtual server configured with non-default lasthop configurations no longer crashes.

---

646604-4 : Client connection may hang when NTLM and OneConnect profiles used together

Solution Article: K21005334

Component: Local Traffic Manager

Symptoms:
In deployments where a NT LanManager (NTLM) authentication profile and a OneConnect profile are used together in a LTM virtual server to label an authenticated connection to a Domain Controller (DC); if the persisted connection to the DC is re-used, the connection may hang. A connection in this state may not be cleaned up by the sweeper, resulting in a memory leak.

Conditions:
The NTLM and OneConnect profiles are associated with a LTM virtual server.

Impact:
A client connection won't be serviced and TMM memory will leak. Over a long time period, this may result in more widespread service disruptions.

Workaround:
Avoid the use of OneConnect profiles on virtual servers that use NTLM profiles. The connections to the Domain Controller won't be pooled, but all other features will be retained.

Fix:
Fixed a problem that prevented NTLM and OneConnect profiles from working properly on the same LTM virtual server.

645615-4 : zxfrd may fail and restart after multiple failovers between blades in a chassis.

Solution Article: K70543226

Component: Global Traffic Manager (DNS)

Symptoms:
zxfrd may fail and restart after multiple failovers between blades in a single chassis.

Conditions:
DNS Express must be configured in a multi-blade chassis. If a blade transitions from active to backup to active states and the DNS Express (tmmdns.bin) database has been re-created while the blade was in backup status, zxfrd may fail when attempting to reference old data.

Impact:
zxfrd will create a core file and restart, picking up where it left off.

Workaround:
None.

Fix:
The cause of the failure is now addressed.

---

645589 : Password-less ssh access lost for non-admin users after tmsh load sys ucs

Component: TMOS

Symptoms:
During the load of ucs, the $HOME/.ssh/authorized_keys file is moved to /etc/ssh/<user> and then a symbolic link is pointed to that file in the $HOME/.ssh such that the ucs load modification of ownership won't break the password-less ssh access to the BIG-IP. The problem is that the /etc/ssh/<user> directory has no other-group read permissions and non-admin users can't read the file and hence the password-less access is denied and a password is requested.

Conditions:
Always happens as the permissions for /etc/ssh/<user> are 0700 (user read-write-execute only) and it is owned by root.

Impact:
Non-admin users lose password-less access to their BIG-IP after tmsh load sys ucs.

Workaround:
An admin user needs to manually change the permissions of the /etc/ssh and /etc/ssh/<user> permissions to be 0755.

A non-admin user has no such capability and thus has no workaround.

Fix:
By simply setting the umask to 0022 prior to the call to mkpath (with 0755 permissions) makes the /usr/local/bin/install_ucs.pm script behave as expected.

The override of the umask is then set back to previous value as to not affect the script elsewhere.

645179-4 : Traffic group becomes active on more than one BIG-IP after a long uptime

Component: TMOS

Symptoms:
Traffic-groups become active/active for 30 seconds after a long uptime interval.

Note: Uptime required to encounter this issue is dependent on the number of traffic groups: the more traffic groups, the shorter the uptime.

For example:

-- For 7 traffic groups, the interval is ~710 days.
-- For 15 traffic groups, the interval is ~331 days.

Conditions:
-- Two or more BIG-IP systems defined in a device group for sync/failover.
-- There is one or more traffic groups configured.
-- The BIG-IP systems have a long uptime.

Impact:
Outage due to traffic-group members being active on both systems at the same time.

Workaround:
There is no workaround.

The only option is to reboot all the BIG-IP units in the device group on a regular interval. The interval is directly dependent on the number of traffic groups.

Fix:
Traffic groups no longer becomes active on more than one BIG-IP system in a device group after a long uptime interval.

Component: Global Traffic Manager (DNS)

Symptoms:
Under LTM :: Virtual Servers :: Properties, the "Link" value sometimes displays "none" when it should display an actual link name.

Conditions:
This happens under certain configuration of Self IP / GTM Servers / GTM Links / LTM Virtual Servers.

Impact:
When conditions are met, the Virtual Server's link information displayed is not correct.

Workaround:
None.

Fix:
Virtual Server's assigned Link on the LTM Virtual Server Properties page is now displayed correctly.

644184-6 : ZebOS daemons hang while AgentX SNMP daemon is waiting.

Solution Article: K36427438

Component: TMOS

Symptoms:
ZebOS daemons hang while AgentX SNMP daemon is unresponsive.

Conditions:
- Dynamic routing is enabled.
- SNMP is enabled.
- SNMP is unresponsive which could be caused by several issues such as snmpd calling an external script that takes several moments to return or mcpd is slow to respond to snmpd queries.

Impact:
Dynamic routing may be halted for the duration of AgentX daemon being busy.

Workaround:
If snmpd is calling external scripts that take several moments to return, then stop using the external script.

Fix:
ZebOS daemons no longer hangs while AgentX is waiting.

642330-4 : GTM Monitor with send/receive string containing double-quote may cause upgrade to fail.★

Component: Global Traffic Manager (DNS)

Symptoms:
When you upgrade from an affected version, the config gets saved before moving to the new version, thus dropping the enclosing quotes and causing a load failure when booting into the new version.

Conditions:
Configuration where monitor string contains \" (backslash double-quote) but does not contain one of the following characters: ' (single quote), | (pipe), { (open brace), } (close brace), ; (semicolon), # (hashtag), literal newline, or literal space.

Impact:
Configuration fails to load.

Workaround:
Manually edit each string in the BIG-IP_gtm.conf to include enclosing quotes in order to get the config to load the first time.

Fix:
Configs load successfully after upgrade. Surrounding quotes, if missing, are added to strings in the BIG-IP_gtm.conf file after upgrade. For example:
\"service_status\":\"on\".+\"maintenance\":\"off\" in the recv, send recv-disable and username fields. Output of list gtm monitor and bigip.conf match. Reloading the same config via tmsh does not cause unintentional changes, such as losing a level of escape in monitor strings.

642039-4 : TMM core when persist is enabled for wideip with certain iRule commands triggered.

Component: Global Traffic Manager (DNS)

Symptoms:
tmm cores with SIGSEGV.

Conditions:
This occurs when persist is enabled for wideip, and an iRule with the following commands triggered:
forward
reject
drop
discard
noerror
host

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Disable persist on wideip.

Note: Although this is not an ideal workaround, it provides a way that to use those iRule commands without causing a tmm core.

Fix:
TMM no longer coreswhen persist is enabled for wideip with certain iRule commands triggered.

641512-2 : DNSSEC key generations fail with lots of invalid SSL traffic

Solution Article: K51064420

Component: Local Traffic Manager

Symptoms:
DNSSEC keys can rollover periodically. This will fail, leading to no keys to sign DNSSEC queries (no RRSIG records) when the BIG-IP is handling a lot of SSL traffic with invalid certificates.

The system posts the following log signature in /var/log/ltm:
err tmm1[12393]: 01010228:3: DNSSEC: Could not initialize cipher context for key /Common/x1-zsk.

Conditions:
DNSSEC keys configured with periodic rollover. The certificate path queues an error (situations include but not limited to lots of SSL traffic with invalid certificates).

Impact:
DNSSEC key generations fail to be accepted by the TMM so that when the prior generation expires there is no valid certificate to sign DNSSEC queries.

Workaround:
Restart the TMM after the new key generation is created.

Fix:
DNSSEC key generations now complete successfully, even with a lot of SSL traffic with invalid certificates.

Component: TMOS

Symptoms:
GRE tunnel traffic can be sent to one TMM if BIG-IP doesn't proxy the GRE tunnel and uses forwarding virtual to handle GRE tunnel traffic.

Conditions:
Use forwarding virtual to handle GRE tunnel traffic.

Impact:
GRE tunnel traffic can overwhelm the one TMM and cause performance degradation.

Workaround:
None.

Fix:
Improved GRE tunnel traffic handling so traffic does not overwhelm one TMM and cause performance degradation.

639575-3 : Using libtar with files larger than 2 GB will create an unusable tarball

Solution Article: K63042400

Component: TMOS

Symptoms:
Programs such as qkview create a .tar file (tarball) using libtar. If any of the files collected are greater than 2 GB, the output tar file cannot be read by /bin/tar.

This occurs due to a limitation of the file compression library employed by qkview command; the system cannot collect files larger than 2 GB in size in a Qkview.

The qkview command may generate output that iHealth cannot parse, and that the tar command cannot extract.

Conditions:
-- The file collected via libtar (e.g., by qkview or other program dynamically linking with /usr/lib/libtar-1.2.11) is greater than 2 GB.
-- A 2 GB or larger file exists in a directory that qkview normally collects.

Impact:
No qkview diagnostics file is created. Although you can extract the qkview tarball using /usr/bin/libtar, the file will be a zero-length file. Cannot submit a qkview to iHealth for analysis. Other applications using libtar will produce invalid tar files.

Workaround:
Remove the file larger than 2 GB from the system prior to running qkview or other program that uses libtar.

Fix:
With the fix to third party software, libtar, programs using libtar no longer create an unusable tarball when dealing with files larger than 2 GB.

638935-1 : Monitor with send/receive string containing double-quote may cause upgrade to fail.★

Component: TMOS

Symptoms:
When you upgrade from an affected version, the config gets saved before moving to the new version, thus dropping the enclosing quotes and causing a load failure when booting into the new version.

Conditions:
Configuration where monitor string contains \" (backslash double-quote) but does not contain one of the following characters: ' (single quote), | (pipe), { (open brace), } (close brace), ; (semicolon), # (hashtag), literal newline, or literal space.

Impact:
Configuration fails to load.

Workaround:
Manually edit each string in the bigip.conf to include enclosing quotes in order to get the config to load the first time.

Fix:
Configs load successfully after upgrade. Surrounding quotes, if missing, are added to strings in the bigip.conf file after upgrade. For example:
\"service_status\":\"on\".+\"maintenance\":\"off\" in the recv, send recv-disable and username fields. Output of list ltm monitor and bigip.conf match. Reloading the same config via tmsh does not cause unintentional changes, such as losing a level of escape in monitor strings.

If you have an escaped quote in your configuration, and are moving to a configuration with this the dependency of this fix, you cannot reload the configuration or the license which also reloads the configuration. Doing so, will cause the config load to fail.

633723-1 : New diagnostics run when a crypto HA failure occurs and crypto.ha.action is reboot

Component: Local Traffic Manager

Symptoms:
A new db variable has been added to print diagnostic information when Cavium Nitrox devices encounter a 'request queue stuck' error. When this occurs, the system posts a log message such as:
crit tmm1[19936]: 01010260:2: Hardware Error(Co-Processor): cn1 request queue stuck.

Conditions:
-- A Cavium Nitrox 'request queue stuck' error occurs.
-- The db variable 'crypto.ha.action' is set to reboot.

Impact:
The system will automatically run 'nitrox_diag' to collect diagnostic information to help F5 determine the cause of the queue stuck error before rebooting.

The system immediately fails over to the standby system, but will then spend approximately one minute gathering diagnostic information before rebooting.

See https://support.f5.com/csp/article/K95944198 for more information about nitrox_diag.

Workaround:
None.

Fix:
The system now automatically gathers nitrox data collection when request queue stuck errors occur.

Behavior Change:
Under rare conditions, the system will take approximately one additional minute to reboot.

If a Cavium Nitrox 'request queue stuck' error occurs and the db variable 'crypto.ha.action' is set to reboot, the system will automatically run 'nitrox_diag' to collect diagnostic information to help F5 determine the cause of the queue stuck error before rebooting.

When the error happens, failover to the standby system will still happen immediately. The delay occurs only on rebooting the system that has already gone to standby mode.

633691-2 : HTTP transaction may not finish gracefully due to TCP connection is closed by RST

Component: Local Traffic Manager

Symptoms:
HTTP or other higher layer protocol transactions may not finish gracefully due to TCP connection is closed by RST.

Conditions:
1. There is ClientSSL or ServerSSL configured on the Virtual Server.
2. HTTP or other higher layer protocol has not finished the translations yet.
3. Client or Server sends out the TCP FIN packet.

Impact:
Application-level responses may not be received at all by the client.

Workaround:
No Workaround.

Fix:
TMM should try to use the TCP FIN to close the connection gracefully as much as possible instead of using RST which will abandon the data which has not been sent out to the wire.

633465-1 : Curl cannot be forced to use TLSv1.0 or TLSv1.1

Solution Article: K09748643

Component: TMOS

Symptoms:
Curl fails when connecting to server that does not accept TLSv1.1 or TLSv1.2 handshakes. This occurs even if the "--tlsv1.0" or "--tlsv1.1" options to the curl command are used.

Conditions:
Curl is used to attempt to connect to a server that does not understand TLSv1.1 and/or TLSv1.2 handshakes. This occurs when using software v11.5.4 HF2 through 11.5.6 or v11.6.1 HF1 through 11.6.3.

Impact:
Curl will fail.

Workaround:
Use "curl-apd" rather than "curl". curl-apd does not currently implement TLSv1.1 or TLSv1.2.

Fix:
Curl now honors the tlsv version flag, so the system correctly uses TLSv1.0, TLSv1.1, or TLSv1.2, as specified.

632423-1 : DNS::query can cause tmm crash if AXFR/IXFR types specified.

Solution Article: K40256229

Component: Global Traffic Manager (DNS)

Symptoms:
Passing "AXFR" or "IXFR" as the type to the DNS::query iRule command can cause a tmm crash.

Conditions:
DNS Express must be enabled when one of the XFR types is used in the DNS::query iRule command.

Impact:
tmm will crash and restart every time this command is issued. Traffic disrupted while tmm restarts.

Workaround:
Do not explicitly use AXFR or IXFR query types.

If the [DNS::question type] command is being used to dynamically pass in the type, add a preceding check similar to the following:

if { not [DNS::question type] ends_with "XFR" } {
    set rrs [DNS::query dnsx [DNS::question name] [DNS::question type]]
}

Fix:
The iRule now provides an error message in /var/log/ltm indicating that AXFR and IXFR are not valid types to use with the DNS::query command, and no tmm crash occurs as a result.

631627-3 : Applying BWC over route domain sometimes results in tmm not becoming ready on system start

Component: TMOS

Symptoms:
Rebooting after applying BWC to route domain stops vlan traffic on VCMP guest. You will experience connection failures when bandwidth Controller (bwc) and Web Accelerator are enabled.

Running the tmsh show sys ha-status all-properties command will indicate that tmm is in "ready-for-world", but the Fail status will read "Yes" when this is triggered.

Conditions:
BWC enabled and associated with a route domain, Web Accelerator is enabled, and the system is rebooted.

Impact:
The system does not comes up fully. TMM does not reach a ready state and will not pass traffic.

Workaround:
Remove BWC from route domain and then reapply the BWC back.

Fix:
BWC enabled and associated with a route domain, Web Accelerator enabled, and the system is rebooted, now results in the system and TMM coming up fully and passing traffic.

629771 : the TCP::unused_port does erroneous accept IPV4_COMPAT addresses

Component: Local Traffic Manager

Symptoms:
when calling TCP::unused_port command with a tcl ip addr object which represents the IPv4 address as IPv4-Compatible IPv6 address,
the function searches for existing flows related to this address.
IPv4-Compatible IPv6 addresses are deprecated, the flow table uses IPv4-Mapped IPv6 address

Conditions:
the IP::Addr object has been crafted with the following command

[IP::addr <addr> mask ::ffff:ffff]

Impact:
The TCP::unused_port command is unable to return an unused port

Workaround:
use the string representation by forcing the object to be a string
e.g.

 set ipv6_addr "fe80::250:56ff:0a1e:0101"
      set ipv4_from_ipv6 [ string tolower [IP::addr $ipv6_addr mask ::ffff:ffff] ]

629530-8 : Under certain conditions, monitors do not time out.

Solution Article: K53675033

Component: Global Traffic Manager (DNS)

Symptoms:
Some monitored resources are marked as "Unknown" when the actual status is "offline".

Conditions:
This can rarely occur when the monitor timeout period elapses when either no response has been received, or a response has been received indicating that the resource is "down" and the monitor is configured to ignore down responses. It is more likely to occur when many monitor timeout periods elapse at the same time, and the monitor timeout value is evenly divisible by the monitor's monitor interval.

Impact:
The status of the monitored resource is incorrect. This does not materially affect the operation of the system since resources marked "Unknown" will not be used.

Workaround:
Disable the affected resources, and then enable them again.

Fix:
The resource status is now correct under all monitor timeout conditions.

629033-1 : BIG-IP should send SHA1 in supported signature hash algorithm last (clientside / Server Hello).

Component: Local Traffic Manager

Symptoms:
BIG-IP should send SHA1 in supported signature hash algorithm last (clientside / Server Hello). Instead, the BIG-IP system is sending SHA1 signature algorithms in the Server Hello first.

Conditions:
clientside / Server Hello.

Impact:
Minimal. SHA1 algorithms are listed first and they should be last.

Workaround:
None.

Fix:
The system now reorders signature hash algorithms such that SHA1 is last.

628164-1 : OSPF with multiple processes may incorrectly redistribute routes

Solution Article: K20766432

Component: TMOS

Symptoms:
When OSPF is configured with multiple processes that each redistribute different type routes, LSAs may be created in a process for a route of the type other than the one configured for redistribution into that process.

Conditions:
OSPF routing with multiple processes configured. Each OSPF process configured with a different route type redistributed.

Impact:
Incorrect routing information in the network when OSPF converges.

Workaround:
Redistribute the leaked route type into the affected OSPF process and use a route map that filters out all routes.

Fix:
OSPF no longer leaks LSAs between processes redistributing different types of routes.

OSPF routes are now created synchronously when the LSA database is updated. If routes are rapidly deleted and re-added, OSPF will send maxage LSAs followed by new LSAs. This is potentially a behavior change where, previously, only a single updated LSA would have been sent.

If the dnsxdump diagnostic tool is run when the DNS Express database has a DNS resource record using a non-standard type, the process may crash providing incomplete diagnostic output.

Conditions:
Running dnsxdump with a DNS Express database containing non-standard resource record types.

Impact:
dnsxdump provide incomplete diagnostic output, stopping on the zone containing the resource record with the non-standard type.

Workaround:
This is primarily known to be caused by non-standard RR types created for WINS records. Removing the WINS records from the master nameserver, will allow dnsxdump to work again after the next zone transfer.

Fix:
dnsxdump handles non-standard resource record types.

624263-1 : iControl REST API sets non-default profile prop to "none"; properties not present in iControl REST API responseiControl REST API, sets profile's non-default property value as "none"; properties missing in iControl REST API response

Component: TMOS

Symptoms:
For profiles, iControl REST does not provide visibility for profile property override when "none" is specified, including references, passwords, and array of strings.

Conditions:
-- Use iControl REST API.
-- string, enum, or vector of enum/string property explicitly set to "none" for a component within any REST API endpoint specialized in /etc/icrd.conf.

Impact:
The iControl REST API response skips these elements. iControl REST does not provide visibility for profile property overrides.

Workaround:
None.

Fix:
iControl REST API now returns elements (i.e., string, enum, or vector of enum/string property that is explicitly set to "none" for a component within any REST API endpoint specialized in /etc/icrd.conf) with a value "none". The exclusion to this policy is the secured attributes. Secured attributes are always excluded from the iControl REST API response.

624193 : Topology load balancing not working as expected

Component: Global Traffic Manager (DNS)

Symptoms:
Under certain conditions, load balancing decisions can result in an unequal or unexpected distribution.

Conditions:
Occurs when topology load balancing is used for a wide IP and more than one pool share the highest assigned score for a particular load balancing decision.

Impact:
The resulting load balancing decisions can lead to an unequal or unexpected distribution of pool selections.

Workaround:
Topology records and pools can be configured to avoid the conditions which cause the condition.

Fix:
A system DB variable, gtm.wideiptoporandom, has been added. When this system DB variable is assigned the value of "enable" and more than one pool shares the highest assigned score for a given load balancing decision, a random pool is selected.

Component: TMOS

Symptoms:
If a vlangroup is configured within a vCMP guest, under some circumstances unicast packets may be looped between the switchboard and the BIG-IP guest. This is most likely to occur when the guest is part of an HA pair.

Conditions:
vCMP guest, vlangroups.

Impact:
High CPU utilization and potentially undelivered packets.

Workaround:
Correctly configure proxy ARP excludes on the vlangroup and increase the FDB timeout by setting the vlan.fdb.timeout database key to a larger value such as 3600.

Fix:
Packets are no longer looped between vlangroup children on vCMP guests.

620659-1 : The BIG-IP system may unecessarily run provisioning on successive reboots

Component: TMOS

Symptoms:
After the first boot, the system runs provisioning and boots successfully, but there is a file left on the system /mprov_firstboot. This will appear in /var/log/ltm:
  info mprov:4614:: \'\'provision.initialized\' indicates force TMOS only provisioning - forcing.\'

During a subsequent boot, provisioning will run again, potentially unnecessarily, due to the existence of this file. The following will appear in /var/log/ltm during the second boot:
  info mprov:4609:: \'Existence of file \'/mprov_firstboot\' indicates force TMOS only provisioning - forcing.\'

Conditions:
The memory size of the host changes and there is some other need for reprovisioning (for example a new configuration load).

Impact:
On a vCMP host, the second provisioning may not complete properly and guest systems will not pass traffic.

The vCMP host will continually try to start more than one tmm and fail when there should only be one tmm running. The /var/log/tmm logfile on the vCMP host will contain:
  <13> Sep 25 01:33:28 vcmphost1 notice Too small memsize (60) -- need at least 136 MB

The /var/log/tmm logfile on the vCMP guest will contain:
  <13> Sep 25 01:38:21 bigip1 notice Failed to write /var/run/libdag.so_2, err: -30
  <13> Sep 25 01:38:21 bigip1 notice panic: vdag failed to attach
  <13> Sep 25 01:38:21 bigip1 notice ** SIGFPE **

Workaround:
If the vCMP host is in a tmm restart loop due to this issue, reboot the vCMP host to allow the system to come up properly.

Fix:
The BIG-IP software now always removes the /mprov_firstboot file when the system is reprovisioned.

617862-3 : Fastl4 handshake timeout is absolute instead of relative

Component: Local Traffic Manager

Symptoms:
TCP connections that are pending completion of the three-way handshake are expired based on the absolute value of handshake timeout. For example, if handshake timeout is 5 seconds, then the connection is reset after 5 seconds of receiving the initial SYN from the client.

Conditions:
A TCP connection in three-way handshake.

Impact:
Connections are expired prematurely if they are still in three-way handshake.

Workaround:
Disable handshake timeout.

Impact of workaround: Your TCP handshake will not prematurely timeout and connections remains open until the Idle Timeout expires.

Fix:
The handshake timeout now expires based on idleness of the connection, taking into consideration of any SYN retransmissions, etc., that might occur.

---

616242-1 : basic_string::compare error in encrypted SSL key file if the first line of the file is blank★

Solution Article: K39944245

Component: TMOS

Symptoms:
Trying to load a configuration that references an encrypted SSL key file may fail if the first line of the SSL key file is blank. When this occurs, the system will report a vague error message:

    01070711:3: basic_string::compare

If this happens during an upgrade, the system will not load the configuration under the new software version, and will remain inoperative.

Conditions:
This can occur if an affected configuration is present on a system running BIG-IP v11.3.0 or earlier, and is upgraded to BIG-IP v11.4.0 through v12.1.1.

Impact:
Configuration fails to load on upgrade with extremely unhelpful error message, and absolutely no indication as to what file was being processed at the time (or that this relates to a filestore file).

Workaround:
Remove the newlines at the beginning of any SSL key files that begin with a newline. During an upgrade scenario, edit the files in the filestore.

614865 : Overwrite flag in iControl functions key/certificate_import_from_pem functions is ignored and might result in errors.

Component: TMOS

Symptoms:
Overwrite flag in iControl functions key/certificate_import_from_pem functions is ignored and might result in errors.

Specifically, the functions are:
key_import_from_pem()
certificate_import_from_pem()
key_import_from_pem_v2()
certificate_import_from_pem_v2()

Conditions:
When there is an existing key or certificate on the BIG-IP system, and you want to overwrite them using key_import_from_pem(), certificate_import_from_pem(), key_import_from_pem_v2(), or certificate_import_from_pem_v2() iControl calls, it results in errors stating that the key or certificate already exists on the BIG-IP system.

Impact:
Cannot overwrite the key/certificate file-objects using these iControl calls.

Workaround:
There are two workarounds:
- Delete and import the key/certificate using key_import_from_pem(), certificate_import_from_pem(), key_import_from_pem_v2(), or certificate_import_from_pem_v2() iControl calls.

- Use key_import_from_file and certificate_import_from_file iControl calls as an alternative to import key/certificate from a file.

Fix:
Overwrite flag in iControl functions key/certificate_import_from_pem_v2() functions are now processed correctly and no longer produce errors.

614675 : GUI or iControl SOAP API call 'LocalLB::ProfileClientSSL::create_v2' creates invalid profile

Component: TMOS

Symptoms:
1. Using the GUI or an iControl SOAP call can create invalid client SSL profile containing an empty cert-key-chain. This might occur after following these steps:
 -- Create new client-ssl cert from the GUI (the web-based UI).
 -- Check 'Custom' in 'Certificate Key Chain', but do not add anything.
 -- Click Finished. The system creates the following:

        ltm profile client-ssl /Common/cssl {
            app-service none
            cert none
            cert-key-chain {
                "" { }
                defualt_rsa_ckc { <=== a typo "defualt"
                    cert /Common/default.crt
                    key /Common/default.key
                }
            }
            <snip>
        }

2. Using the iControl function 'LocalLB::ProfileClientSSL::create_v2' creates a profile with two cert-key-chain objects containing identical cert and key values, but with different names:

      ltm profile client-ssl my_prof {
          app-service none
          cert mycert.crt
          cert-key-chain {
              "" {
                  cert mycert.crt
                  key mycert.key
              }
              defualt_rsa_ckc { <=== a typo "defualt"
                  cert mycert.crt
                  key mycert.key
              }
          }
          chain none
          inherit-certkeychain false
          key mycert.key
          passphrase none
      }

Conditions:
Creating client SSL profiles using the GUI or the iControl function create_v2().

Impact:
Cannot add the invalid client SSL profile to a virtual server.

Workaround:
Remove the invalid client SSL profile and re-create the profile using TMSH or the GUI.

Fix:
GUI or iControl SOAP API call 'LocalLB::ProfileClientSSL::create_v2' no longer creates an invalid profile when creating client SSL profiles using the iControl function create_v2(). In addition, 'defualt' has been changed to 'default', as expected.

613524-1 : TMM crash when call HTTP::respond twice in LB_FAILED

Component: Local Traffic Manager

Symptoms:
TMM core-dumps when these conditions are met:
- LB_FAILED event
- irule script must use a "delay" (parked) statement together with two HTTP::respond statements.

Conditions:
- LB_FAILED event must be triggered by good IP address and bad port so that the serverside connflow is establish. you will not see this bug if no pool member is used or invalid IP address is used.
- irule script must use a "delay" (parked) statement. the delay together with http response creates the right timing for the client side connflow to go away while proxy is pushing Abort event down to both clientside and serverside.

Impact:
Traffic disrupted while tmm restarts.

610417-4 : Insecure ciphers included when device adds another device to the trust. TLSv1 is the only protocol supported.

Solution Article: K54511423

Component: TMOS

Symptoms:
When adding a device to the trust, the SSL connection can use insecure ciphers. Also it will use the undesirable TLSv1 protocol instead of negotiating to the highest safest protocol available which is TLSv1.2

If the peer device is configured to use TLSv1.1 or TLSv1.2 only, device trust will not be established

Conditions:
This exists when configuring devices in a device cluster.

Impact:
Unable to configure stronger ciphers for device trust.

If the peer device is modified to not use TLSv1.0, it is impossible to establish Device Trust.

Workaround:
None.

Fix:
Advertised client ciphers reduced to what the common criteria compliance standard approves.
Changed the initial OpenSSL call to use the correct one to negotiate to the highest available TLS protocol (1.2).

608320-2 : iControl REST API sets non-default persistence profile prop to "none"; properties not present in iControl REST API responseiControl REST API, sets persistence profile's non-default property value as "none"; properties missing in iControl REST API response

Component: TMOS

Symptoms:
For persistence profiles, iControl REST does not provide visibility for property override when "none" is specified, including references, passwords, and array of strings.

Conditions:
-- Use iControl REST API with persistence profiles.
-- string, enum, or vector of enum/string property explicitly set to "none" for a component within any REST API endpoint specialized in /etc/icrd.conf.

Impact:
The iControl REST API response skips these elements. iControl REST does not provide visibility for persistence profile property overrides.

Workaround:
None.

Fix:
iControl REST API now returns persistence profile elements (i.e., string, enum , or vector of enum/string property that is explicitly set to "none" for a component within any REST API endpoint specialized in /etc/icrd.conf) with a value "none". The exclusion to this policy is the secured attributes. Secured attributes are always excluded from the iControl REST API response.

606575-2 : Request-oriented OneConnect load balancing ends when the server returns an error status code.

Component: Local Traffic Manager

Symptoms:
Request-oriented OneConnect load balancing ends when the server returns an error status code.

Conditions:
OneConnect is enabled and the server responds with a HTTP error status code.

Impact:
The client remains connected to the server, and no further load-balancing decisions are made.

Workaround:
It may be possible to detect the HTTP status code in the response, and manually detach the client-side.

To do so, use an iRule similar to the following:

when HTTP_RESPONSE {
    if { [HTTP::status] == 200 } { return }
    if { [HTTP::status] == 401 } {
        set auth_header [string tolower [HTTP::header values "WWW-Authenticate"]]
        if { $auth_header contains "negotiate" || $auth_header contains "ntlm" } {
            # Connection-oriented auth. System should already be doing the right thing
            unset auth_header
            return
        }

        unset auth_header
    }

    catch { ONECONNECT::detach enable }
}.

Note: These workarounds should not be used when the backend server is using connection-oriented HTTP authentication (e.g., NTLM or Negotiate authentication).

Fix:
With OneConnect, the client-side remains detachable when the server-side returns an HTTP error status code.

605865-1 : Debug TMM produces core on certain ICMP PMTUD packets

Component: Local Traffic Manager

Symptoms:
The debug TMM will produce a core on the assert "cwnd or ssthresh too low" when receiving an ICMP PMTUD packet with an MTU larger than the current MTU. This does not affect the default TMM.

Conditions:
While using the debug TMM, an ICMP PMTUD packet is received with an MTU larger than the current MTU.

Impact:
Debug TMM crashes on assert "cwnd or ssthresh too low." Traffic disrupted while tmm restarts.

Workaround:
Block incoming ICMP PMTUD packets. Note that this will cause Path MTU Discovery to fail, and IP packets sent by the BIG-IP system with the Don't Fragment (DF) bit set may be dropped silently if the MTUs of the devices on the path are configured incorrectly.

Fix:
The system now always updates TCP MSS after an ICMP PMTUD packet, so there is no debug TMM core.

605476 : statsd can core when reading corrupt stats files.

Component: TMOS

Symptoms:
-- The istatsd process produces a core file in the /shared/core directory.

Conditions:
This issue occurs when the following condition is met:

The istatsd process attempts to read a corrupt iStats segment file with duplicate FIDs.

Under these conditions, the istatsd process continually consumes memory which produces a core causing the istatsd process to restart.

Impact:
iStatsd process will restart due to resource exhaustion.

Workaround:
To work around this issue, you can remove the iStats files and restart the istatsd processes. To do so, perform the following procedure:

Impact of workaround: This workaround will cause all statistics in the iStats files to reset.

1. Log in to the BIG-IP command line.
2. To stop the istatsd and related processes, type the following command:
tmsh stop sys service istatsd avrd merged.

3. To delete the iStats files, type the following command:
find /var/tmstat2/ -depth -type f -delete.

4. To start the istatsd and related processes, type the following command:
tmsh start sys service istatsd avrd merged.

Fix:
Added a fix to protect against a continually reading a segment file that is corrupted and has Duplicate Fids.

605270-3 : On some platforms the SYN-Cookie status report is not accurate

Component: TMOS

Symptoms:
On a vCMP guest, after a ePVA-enabled virtual server enters SYN Cookie mode, the FPGA will never leave SYN Cookie mode even though BIG-IP has returned to normal mode.

Conditions:
This occurs intermittently on virtual servers with ePVA enabled on a vCMP instance where SYN Protection is triggered.

Impact:
Since this occurs very intermittently, the entire impact is not known. Initially this is an incorrect SYN Cookie status reporting issue for LTM Virtual statistics, but it is possible that if SYN Cookie mode is triggered again, hardware SYN might not be enabled properly.

Workaround:
Upgrade with new fixes for this.

Fix:
BIG-IP FPGAs now correctly report hardware SYN Cookie mode.

603945-3 : BD config update should be considered as config addition in case of update failure

Component: Application Security Manager

Symptoms:
A configuration update fails when the system cannot find the item to update. Configuration failures are shown in bd.log.

Conditions:
The condition that leads to this scenario is not clear and is still under investigation.

Impact:
The update fails and the entity is not added.

Workaround:
Delete the faulty entity and re-add, and then issue the following command: restart asm.

This fixes the issue in the cases in which it is a single entity.

Fix:
A configuration update no longer fails when the system cannot find the item to update. Now, the system adds the item with its updated value if the entity does not already exist. Otherwise, the operation updates the value of the existing entry.

603723-1 : 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:
None.

Fix:
The system now successfully handles TLS v1.0 fallback when pool members are configured to use TLS v1.2 only, so pool members are correctly marked as being up.

603667-1 : TMM may leak or corrupt memory when configuration changes occur with plugins in use

Component: Local Traffic Manager

Symptoms:
TMM may leak memory when plugins are in use and the plugin is re-initialized (typically due to configuration changes). In rare cases, memory corruption may occur causing TMM to restart.

Conditions:
Plugin-based functionality configured (ASM, APM, etc.) and configuration changes occur.

Impact:
The memory leakage generally occurs infrequently and at a rate that TMM operations are not affected. However, when memory corruption occurs, a traffic interruption may occur due to TMM restarting.

Workaround:
No workaround except disabling plugin-based functionality (such as ASM, APM, etc.).

Fix:
TMM now properly manages plugin memory, and no longer leaks or corrupts this memory.

603598-1 : big3d memory under extreme load conditions

Component: Global Traffic Manager (DNS)

Symptoms:
big3d memory consumption can grow if big3d is unable to process monitor requests in a timely fashion.

This can be seen by monitoring the memory consumption of big3d using standard OS tools such as top.

Conditions:
big3d maintains a queue for monitor requests.
Incoming monitor requests are first placed in the Pending queue.
Requests are moved from the Pending queue to the Active queue, if there is room in the Active queue.

When the Pending queue is full, there is no room for the Monitor Request. big3d attempts to clean up the Monitor request, but fails to completely free the memory.
This might result in a significant memory leak.

For this to happen, the Active queue must be full as well as the Pending queue.

One possible condition that might cause this is if multiple Monitors time out. This results in Monitors having long life times, which keeps the Active queue full.

Thus the Pending queue might become full and the memory leak can occur.

In BIG-IP 11.1.0 versions of big3d,
the Active queue has 256 slots and
the Pending queue has 4096 slots.

In BIG-IP 11.1.0-hf3, the queue sizes were expanded to
2048 for the Active queue and 16384 for the Pending queue.

Since the queues were smaller n versions prior to
11.1.0-hf3, this leaks is more likely to manifest itself.

In later versions, the leak is still possible, but is less likely to occur.

Impact:
big3d memory consumption grows unbounded. This might result in a big3d restart or memory starvation of other processes.

Workaround:
This can be partially mitigated by ensuring that monitors
settings are reasonable and that big3d is not overloaded.

This will minimize the chances that the Pending queue
does not become full.

There is no mechanism to resize the queues.

Fix:
When a monitor request is unable to be placed in the queue, the memory for the request is freed properly.

598981-1 : APM ACL does not get enforced all the time under certain conditions

Solution Article: K06913155

Component: Access Policy Manager

Symptoms:
APM ACL does not get enforced all the time under certain conditions

Conditions:
The following conditions individually increase the chances for this problem to occur:
1. The device is very busy. (Construction of ACL windows is prolonged.)
2. Concentration of connections into one TMM. (e.g., VPN feature.)
3. Small number of TMMs (e.g., BIG-IP low-end platform, Virtual Edition (VE) configurations.)
4. Application starts with a high number of concurrent connections.

Impact:
ACL is not applied for subsequent connections for that TMM. This issue does not consistently reproduce.

Workaround:
Mitigation:
Administrator can kill the affected session, which forces the user to re-login, and ultimately restarts the ACL construction process.

Fix:
Switching context when applying ACL is properly processed, and no longer cause ACL to be not enforced.

Example:
ltm rule test_bug {
    when CLIENT_DATA {
    log local0. "[IP::addr 2A01:CB09:8000:46F5::A38:1 mask ::ffff:ffff]"
}

Expected result:
Rule /Common/test_bug <CLIENT_DATA>: 10.56.0.1

Actual result:
Rule /Common/test_bug <CLIENT_DATA>: ::10.56.0.1

Conditions:
using IP::addr to convert an IPv6 to an IPv4 address

Impact:
Address is converted into an IPv4-compatible IPv6 address.

598211-3 : Citrix Android Receiver 3.9 does not work through APM in StoreFront integration mode.

Component: Access Policy Manager

Symptoms:
During the logon to Citrix StoreFront through an APM virtual server, after the login page, the BIG-IP system sends the client the following error: Error 404 file or directory not found.

Conditions:
This occurs when the following conditions are met:
- Citrix Android receiver 3.9.
- APM is in integration mode with Citrix StoreFront.
- Storefront unified experience mode is enabled.

Impact:
Cannot access Citrix StoreFront unified UI through Android Receiver 3.9.

Workaround:
For StoreFront integration mode, there is an iRule that is created by the iApp that redirects the root page to the store's URI. The workaround is to add an additional redirect for the receiver_uri ending with receiver.html. The iRule below contains this workaround.
It is also recommended to delete and recreate the existing store account.

when HTTP_REQUEST {
    if { [regexp -nocase {/citrix/(.+)/receiver\.html} [HTTP::path] dummy store_name] } {
        log -noname accesscontrol.local1.debug "01490000:7: setting http path to /Citrix/$store_name/"
        HTTP::path "/Citrix/$store_name/"
    }
}

Fix:
Citrix Android Receiver 3.9 now works through APM in StoreFront integration mode.

598039-8 : MCP memory may leak when performing a wildcard query

Component: TMOS

Symptoms:
MCP's umem_alloc_80 cache (visible using tmctl -a) increases in size after certain wildcard queries. Accordingly, the MCP process shows increased memory usage.

Conditions:
Folders must be in use, and the user must execute a wildcard query for objects that are in the upper levels of the folder hierarchy (i.e. not at the very bottom of the folder tree).

Impact:
MCP loses available memory with each query. MCP could eventually run out of memory and core, resulting in an outage or failover (depending on whether or not the customer is running in a device cluster).

Workaround:
Do not perform wildcard queries.

Fix:
Stopped MCP leaking when wildcard queries are performed.

595874-3 : Upgrading 11.5.x/11.6.x hourly billing instances to 12.1.0 fails due to license SCD.★

Component: TMOS

Symptoms:
BIG-IP Virtual Edition (VE) instances that use the Amazon Web Services (AWS) hourly billing license model may fail when upgrading to version 12.1.0.

As a result of this issue, you may encounter the following symptom:

After upgrading to version 12.1.0, the BIG-IP VE instance license is invalid.

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

-- You have BIG-IP VE instances that use the hourly billing licensing model.
-- Your BIG-IP VE instances are running 11.5.x or 11.6.x software versions.
-- Your BIG-IP VE instances are running within the AWS EC2 environment.
-- You upgrade the BIG-IP VE instance using the liveinstall method.

Impact:
BIG-IP VE instance licenses are not valid after upgrading to software version 12.1.0.

Workaround:
To work around this issue, you can use the liveinstall method on the hotfix image directly (instead of installing the base software image and then the hotfix image). To do so, perform the following procedure:

Impact of workaround: Performing the following procedure requires rebooting the system and should be performed only during a maintenance window.

Download the BIGIP-12.1.0.0.0.1434.iso and Hotfix-BIGIP-12.1.0.1.1.1447-HF1-ENG.iso files to your workstation. For more information about downloading software, refer to SOL167: Downloading software and firmware from F5.
Copy the downloaded files from your workstation to the /shared/images directory on the VE instance.
To perform the installation by using the liveinstall method, and reboot the BIG-IP VE instance to the volume running the new software, use the following command syntax:

tmsh install sys software hotfix Hotfix-BIGIP-12.1.0.1.1.1447-HF1-ENG.iso volume <volume-number> reboot

For example, to install the hotfix to volume HD1.3 and reboot to the volume running the newly installed software, type the following command:

tmsh install sys software hotfix Hotfix-BIGIP-12.1.0.1.1.1447-HF1-ENG.iso volume HD1.3 reboot
 
Verify the installation progress by typing the following command:
tmsh show sys software

Output appears similar to the following example:

Sys::Software Status
Volume Product Version Build Active Status
----------------------------------------------------------------
HD1.1 BIG-IP 12.0.0 0.0.606 yes complete
HD1.2 BIG-IP 12.1.0 0.0.1434 no complete
HD1.3 BIG-IP 12.1.0 0.0.1434 no installing 6.000 pct

Fix:
BIG-IP VE instances that use the AWS hourly billing license model now complete successfully when upgrading to version 12.1.0.

595773-6 : Cancellation requests for chunked stats queries do not propagate to secondary blades

Component: TMOS

Symptoms:
Canceling a request for a chunked stats query (e.g. hitting ctrl-c during "tmsh show sys connection") does not stop data flowing from secondary blades.

Conditions:
A chassis-based system with multiple blades. Users must execute a chunked stats query (e.g. "tmsh show sys connection") and then cancel it before it finishes (e.g. with ctrl-c in tmsh).

Impact:
Unnecessary data will be sent from TMM to secondary mcpd instances, as well as from secondary mcpd instances to the primary mcpd instance. This could cause mcpd to restart unexpectedly.

Fix:
Cancellations for chunked stats queries are now propagated to secondary blades.

593447-3 : BIG-IP TMM iRules vulnerability CVE-2016-5024

Solution Article: K92859602

---

593390-1 : Profile lookup when selected via iRule ('SSL::profile') might cause memory issues.

Component: Local Traffic Manager

Symptoms:
If an iRule selects a profile using just its name, not the full path, the internal lookup might fail. This might cause a new version of the profile to be instantiated, leading to memory issues.

Conditions:
An iRule calls SSL::profile but does not supply the complete path (e.g., /Common/clientssl); rather, the iRule uses only the profile name.

Impact:
Higher memory usage than necessary.

Workaround:
Always have iRules select profiles using the complete path.

Fix:
If an iRule attempts to select a profile using only its name, the system now prepends the /Common path prior to looking it up, so there is no potential of instantiating another version of the profile, so no memory issue occurs.

<script src="&#10;" type="text/javascript"></script>

Impact:
Web application may not work correctly.

Workaround:
In most cases HTML entities can be replaced by appropriate characters by iRule.

Fix:
Now rewrite correctly handles HTML entities in attribute values.

---

592854-2 : Protocol version set incorrectly on serverssl renegotiation

Component: Local Traffic Manager

Symptoms:
If the BIG-IP serverssl profile sends a new ClientHello request to renegotiate SSL, the protocol version will be set to 0. This will cause renegotiation to fail.

Conditions:
ServerSSL profile configured on a virtual server, and BIG-IP initiates a renegotiation.

Impact:
Protocol field is invalid (0), and the server will reset the connection.

Fix:
Fixed a reset issue with SSL renegotiation in the serverssl profile.

---

592784 : Compression stalls, does not recover, and compression facilities cease.

Component: Local Traffic Manager

Symptoms:
Compression stalls, does not recover, and compression facilities may cease.

Conditions:
A device error of any kind, or requests that result in the device reporting an error (for example, attempting to decompress an invalid compression stream).

Impact:
In general, compression stops altogether. Under some circumstances, compression requests may end up routed to zlib (software compression), but generally the SSL hardware accelerator card does not correctly report that it is unavailable when it stalls.

Workaround:
Select the softwareonly compression provider by running the following tmsh command: tmsh modify sys db compression.strategy value softwareonly.

Fix:
The compression device driver now attempts to recover after a failure. If it still cannot recover, new compression requests will be assigned to zlib (software) for compression.

591828-3 : For unmatched connection, TCP RST may not be sent for data packet

Solution Article: K52750813

Component: Advanced Firewall Manager

Symptoms:
When TCP connection times out (no entry in 'show sys conn'), and subsequent data packet comes in (not SYN), The BIG-IP system does not send a RST to the client to reset the connection.

Conditions:
This issue occurs if AFM is provisioned. Additionally, in BIG-IP v12.1.0 and above, it occurs if ASM is provisioned (regardless of AFM provisioning).

-- Packets other than SYN with no entry in the connection table arrive.

This can occur either after a failover (when mirroring is disabled) when traffic arrives at the newly-active system, or can occur if the relevant virtual server has 'reset-on-timeout' disabled.

Impact:
Client retransmits several times and then terminates TCP connection. There is no RST sent from BIG-IP to client for unmatched connection.

Workaround:
Enable the reset on timeout option to send TCP RST to client when connection times out.

Note: This workaround does not address the circumstances where a newly-active BIG-IP system receives traffic (e.g. after a failover or system reboot).

Fix:
The BIG-IP system now sends a TCP RST for unknown connections so the clients and backend servers can start a new connection.

591666-1 : TMM crash in DNS processing on TCP virtual with no available pool members

Component: Local Traffic Manager

Symptoms:
TMM crash when processing requests to a DNS virtual server.

Conditions:
The issue can occur if a TCP DNS virtual receives a request when no pool members are available to service the request and a DNS iRule is suspended due to previous requests.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Mitigation is to ensure at least one pool member is available whenever the DNS virtual is processing traffic, or to avoid iRule commands that can suspend processing.

Ensure datagram LB mode is enabled on UDP DNS virtuals.

Fix:
Product corrected to prevent crash when there are no available members.

---

591659-2 : Server shutdown is propagated to client after X-Cnection: close transformation.

Solution Article: K47203554

Component: Local Traffic Manager

Symptoms:
Server shutdown is propagated to client after X-Cnection: close transformation.

Conditions:
In OneConnect configurations, when a server's maximum number of keep-alives is exceeded, the server closes the connection between itself and the BIG-IP system. This Connection: Close is transformed to an X-Cnection: close and sent to the Client along with a TCP FIN.

Impact:
Client side connections are closed by the BIG-IP system too early, causing subsequent requests to be dropped.

Workaround:
Set the OneConnect profile "Maximum Reuse" value to 2 below the value of the pool members max keep-alive setting. This forces OneConnect to close the connection before the pool member.

Fix:
Server shutdown is no longer propagated to client after X-Cnection: close transformation, so client side connections are now kept open by the BIG-IP system as expected, and subsequent requests are no longer dropped.

591476-6 : Stuck crypto queue can erroneously be reported

Solution Article: K53220379

Component: Local Traffic Manager

Symptoms:
In some cases, a stuck crypto queue can be erroneously detected on Cavium Nitrox-based (Nitrox PX and Nitrox 3). When the tmm/crypto stats are examined, they show no queued requests. The following message appears in the ltm log: Device error: crypto codec cn-crypto-0 queue is stuck. tmm crash

Conditions:
-- Running on one of the following platforms:
 + BIG-IP 800, 1600, 3600, 3900, 6900, 89xx, 2xxx, 4xxx, 5xxx, 7xxx, 10xxx, 11xxx, 12xxx, i2xxx, and i4xxx
 + VIPRION B41xx-B43xx, B21xx, and B22xx blades.
-- Performing SSL.
-- Under heavy load.

Impact:
The system reports device errors in logs, and takes crypto high availability (HA) action, possibly resulting in failover. Traffic disrupted while tmm restarts.

Workaround:
Modify the crypto queue timeout value to 0 to prevent timeouts using the following command:

tmsh modify sys db crypto.queue.timeout value 0

To clear erroneously stuck queues, you must restart tmm or reboot the BIG-IP system.

Note: Traffic is disrupted while during restarts.

Fix:
The crypto driver now only examines requests in the hardware DMA ring to detect a stuck queue on Nitrox devices.

589400-5 : With Nagle disabled, TCP does not send all of xfrags with size greater than MSS.

Solution Article: K33191529

Component: Local Traffic Manager

Symptoms:
With Nagle disabled, TCP does not send all of xfrags with size greater than MSS.

Conditions:
Congestion window is small relative to message size; abc is enabled; also might manifest when serverside MTU is greater than clientside MTU.

Impact:
Additional connection latency.

Workaround:
Enabling proxy-mss on the serverside TCP profile significantly reduces incidence of this problem in observed cases.

If init-cwnd is low, raising it might also help.

Disabling abc can also reduce the problem, but might have other negative network implications.

Fix:
Incoming packets are now pulled more aggressively into the send buffer, if there are no negative implications for CPU performance.

589379-1 : ZebOS adds and deletes an extraneous LSA after deleting a route that matches a summary suppression route.

Solution Article: K20937139

Component: TMOS

Symptoms:
In a configuration with a summary route that is added to ZebOS and configured with 'not-advertise', when deleting the exactly matching route, ospfd sends LSA route with age 1, then immediately sends update with age 3600.

Conditions:
OSPF using route health injection for default route.

Impact:
No functional impact. The extraneous LSA is immediately aged out.

Workaround:
Configure a static default route in imish instead of using RHI for the default route.

Fix:
ZebOS no longer adds and deletes an extraneous LSA after deleting a route that matches a summary suppression route.

---

589338-2 : Linux host may lose dynamic routes on secondary blades

Component: TMOS

Symptoms:
The Linux host residing on a secondary blade might lose dynamic routes previously learned via a dynamic routing protocol.

Conditions:
- Multibladed chassis or vCMP guest.
- Routes learned via dynamic routing.
- Restart of services or reboot of secondary blade.

Impact:
Routes on Linux host of secondary blade are lost. This might affect host traffic, such as monitoring, remote logging, etc., due to the lack of routing information.

Workaround:
Modify the ZebOS maximum-paths setting on the primary blade to trigger a route update to the non-primary blades.

Add a custom alert to the user_alert.conf to auto-mitigate this issue whenever a blade joins the cluster.

# 11.5.x workaround for user_alert.conf
alert BLADE_JOINED_CLUSTER "010719fc:5: Mate cluster member (.*) turned Green." {
    exec command="/usr/sbin/zebos -a cmd 'enable,conf t,maximum-paths 5,maximum-paths 4,exit,exit'"
}

Note: The Mate cluster log is not present in 11.6.x, so this an 11.5.x only workaround.

Fix:
This issue no longer occurs, so there is consistency among blades.

589256-4 : DNSSEC NSEC3 records with different type bitmap for same name.

Solution Article: K71283501

Component: Global Traffic Manager (DNS)

Symptoms:
For a delegation from a secure zone to an insecure zone, the BIG-IP system returns different type of bitmaps in the NSEC3 record depending on the query type. This causes BIND9's validator to reject the secure delegation to the insecure zone.

Conditions:
For insecure delegations, the DNSSEC implementation does not support the DS record. Those queries are forwarded to the backend, BIND, if selected as fallback. Without ZSK/KSK for an insecure child zone, BIND responds SOA which the system dynamically signs.

Impact:
DNS lookups may fail if BIND9's validator rejects the delegation.

Workaround:
None.

Fix:
If response is a NODATA from either the proxy or a transparent cache, and the query is a DS, set the types bitmap to NS.

---

589039-3 : Clearing masquerade MAC results in unexpected link-local self IP addresses.

Component: Local Traffic Manager

Symptoms:

Conditions:
Masquerade MAC changes from non-zero to zero.

Impact:
This might cause IP address conflicts between devices in a high availability (HA) configuration.

Workaround:
Restart tmm after setting masquerade MAC to zero.

Fix:
The system does not advertise invalid self IP addresses on clearing masquerade MAC.

586878-1 : During upgrade, configuration fails to load due to clientssl profile with empty cert/key configuration.★

Component: TMOS

Symptoms:
During upgrade, configuration fails to load due to invalid clientssl profile cert/key configuration. The validation to verify whether at least one valid key/cert pair exists in clientssl profiles was enforced in software versions through 11.5.0. This validation was not in effect in versions 11.5.1, 11.5.2, and 11.5.3.

The lack of validation resulted in invalid clientssl profiles (those containing empty key/certs or a cert/key of 'default'). When you upgrade such a configuration to 11.5.4 or later, you will receive a validation error, and the configuration will fail to load after upgrade.

Conditions:
The issue occurs when all the below conditions are met.
1. You have a clientssl profile in a configuration from a version without validation (that is, 11.5.1, 11.5.2, or 11.5.3).
2. The clientssl profile in the configuration has an empty cert/key, or a cert/key of 'default'.
3. You upgrade to a version that has the cert/key validation (specifically, 11.5.4, 11.6.0, 11.6.1, and versions 12.1.0 and later).

Impact:
Configuration fails to load. The system posts an error message that might appear similar to one of the following:
-- 01070315:3: profile /Common/my_client_ssl requires a key Unexpected Error: Loading configuration process failed.
-- 01071ac9:3: Unable to load the certificate file () - error:2006D080:BIO routines:BIO_new_file:no such file.
Unexpected Error: Loading configuration process failed.

Workaround:
To workaround this situation, modify the configuration file before upgrading:
1. Check the config file /config/bigip.conf.
2. Identify the clientssl profile without a cert/key.
    For example, it might look similar to the following:
    ltm profile client-ssl /Common/cssl_no-cert-key2 {
        app-service none
        cert none
        cert-key-chain {
            "" { }
        }
        chain none
        defaults-from /Common/clientssl
        inherit-certkeychain false
        key none
        passphrase none
    }

   Note: The profile might have cert-key-chain name but not the cert/key. In other words, it could also appear similar to the following example:
    ltm profile client-ssl /Common/cssl_no-cert-key2 {
        app-service none
        cert none
        cert-key-chain {
            default { }
        }
        chain none
        defaults-from /Common/clientssl
        inherit-certkeychain false
        key none
        passphrase none
    }
3. Remove the clientssl profile from /config/bigip.conf.
4. Run the command: tmsh load sys conf.
5. Re-create the clientssl profiles you need.

585412-1 : SMTPS virtual server with activation-mode allow will RST non-TLS connections with Email bodies with very long lines

Component: Local Traffic Manager

Symptoms:
Connections to a virtual server that uses an SMTPS profile may be reset with a reset cause of 'Out of memory.'

Conditions:
This might occur under the following conditions:
-- A virtual server that uses an SMTPS profile with activation-mode set to allow.
-- A client connection which does not use TLS that sends a DATA section with a text line that is longer than approximately 8192 characters.

8192 characters is an approximation for the maximum line length. The actual problem length can be affected by the MSS value and the particular way that the TCP traffic is segmented.

584310 : TCP:Collect ignores the 'skip' parameter when used in serverside events

Solution Article: K83393638

Component: Local Traffic Manager

Symptoms:
When TCP::Collect is used with 'skip' and 'length' arguments in SERVER_CONNECTED, the "skip' argument does not take effect and is ignored. The Collect works, but collects only the length bytes from start.

Conditions:
TCP:Collect on server side events like SERVER_CONNECTED used with the 'skip' parameter. This is an intermittent issue that have happen only with IIS server.

Impact:
TCP:Collect collects bytes without taking into account the skip, so the bytes collected are not the correct ones.

Workaround:
None.

Fix:
The settings for TCP::Collect command skip and length arguments are now honored during packet processing.

584029-7 : Fragmented packets may cause tmm to core under heavy load

Component: Local Traffic Manager

Symptoms:
In rare circumstances, the Traffic Management Microkernel (TMM) process may produce a core file while processing fragmented packets.

As a result of this issue, you may encounter one or more of the following symptoms:

-- TMM generates a core file in the /shared/core directory.
-- In one of the /var/log/tmm log files, you observe an error message similar to the following example:
 notice panic: ../base/flow_fwd.c:255: Assertion "ffwd flag set" failed.
 panic: ../net/packet.c:168: Assertion "packet is locked by a driver" failed.

notice ** SIGFPE **

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

-- The TMM process offloads a fragmented packet by way of an ffwd operation.
-- Your BIG-IP system is under heavy load.

Impact:
The BIG-IP system temporarily fails to process traffic while the TMM process restarts. If the BIG-IP system is configured for high availability (HA), the system fails over to a peer system.

Workaround:
None.

Fix:
Fragmented packets no longer cause tmm to core under heavy load.

---

583631-1 : ServerSSL ClientHello does not encode lowest supported TLS version, which might result in alerts and closed connections on older Servers.

Component: Local Traffic Manager

Symptoms:
Server SSL ClientHello does not encode lowest supported TLS version. The outer record for a ClientHello contains the same version as the ClientHello. If, for example, the ClientHello is TLS1.2, the outer record will contain TLS1.2. Older servers that do not support later TLS versions might generate an alert and close the connection.

Conditions:
A BIG-IP system with a server SSL profile that supports a TLS version higher than that of the server to which it is connecting.

Impact:
The connection fails. The system might generate an alert.

Workaround:
Force the server SSL profile to use a lower TLS version number by selecting 'No TLSv1.2' or 'No TLSv1.1' in the `options' section of the Server SSL Profile.

Fix:
When enabled by setting the db variable, 'SSL.OuterRecordTls1_0,' to, 'enable,' the outer SSL record will always contain TLS1.0. This is the default. You can use this db variable to prevent an issue in older servers that do not support TLS versions later than 1.0, in which an alert might be generated closing the connection.

Behavior Change:
Formerly, the version present in the ClientHello and the version present in the outer record would match. Now, if the sys db variable, 'SSL.OuterRecordTls1_0,' is set to 'enable' the version present in the outer record will be TLS 1.0 regardless of the version in the ClientHello. This is the default.

583285-2 : BIG-IP logs INVALID-SPI messages but does not remove the associated SAs.

Solution Article: K24331010

Component: TMOS

Symptoms:
The BIG-IP system logs INVALID-SPI messages but does not remove the associated Security Associations (SAs) corresponding to the message.

Note: There are three parts to this issue, as recorded in the following bugs: 569236, 583285, and 662331.

Conditions:
This can occur if an IPsec peer deletes a phase2 (IPsec) SA and does not send a 'notify delete' message to the other peer. The INVALID-SPI message is most likely to be seen when the peer deletes an SA before the SA's agreed lifetime.

Impact:
If the BIG-IP is always the Initiator, the Responder will not initiate a new tunnel if the Responder only handles responses to the BIG-IP clients' traffic. The BIG-IP system continues to use the IPsec SA it believes to be still up. When an SA expires prematurely, some IPsec peers will reject an inbound SPI packet with an ISAKMP INVALID-SPI notify message. If the INVALID-SPI message does not cause new SAs to be created, there will be a tunnel outage until the SA lifetime expires on the defunct SA held on the BIG-IP system.

Workaround:
Manually remove the invalid SA on the BIG-IP system by running the following command:
delete /net ipsec ipsec-sa spi <invalid_spi>

Fix:
Now, when the BIG-IP system receives INVALID-SPI messages, it deletes the invalid Security Association as well as logging the INVALID-SPI message, so the tunnel can initiate again.

Note: There is a three-part fix provided for this issue, as provided in the following bugs: 569236, 583285, and 662331.

580303-2 : When going from active to offline, tmm might send a GARP for a floating address.

Component: Local Traffic Manager

Symptoms:
When moving from active to offline, tmm might send one final GARP for a floating address from the device that is moving offline.

Conditions:
Using high availability, and switching a device from active to offline.

Impact:
The GARP from the offline device can arrive on upstream devices after the GARP from the newly active device, which might poison the address cache of the upstream device. The result is that failover takes longer, since the upstream devices must rediscover the active device.

Workaround:
Use MAC masquerading along with the floating address; the system sends a GARP for the MAC masqueraded address, which prevents the issue.

Fix:
tmm no longer sends a final GARP for a floating address immediately before going offline.

579909-3 : Secondary MCPD exits for APM Sandbox warning improperly treated as configuration error

Component: Access Policy Manager

Symptoms:
Secondary blade MCPD exits if APM Sandbox intends to log a warning message when it fails to remove the corresponding sandbox directory /var/sam/www/webtop/sandbox/files_d/<partition_name>_d while the user is removing the partition.

There are multiple cases that can potentially log such kind of Sandbox warning message and cause an mcpd crash and/or tmm crash. APM can log the warning if it encounters a directory which is not empty, or if the directory does not exist. You will see this error signature in /var/log/ltm:

Mar 11 11:36:49 slot2/viprion-3 warning mcpd[6022]: 010717ac:4: Configuration Warning: Cannot remove directory with symlink to sandbox for partition (p1). Error: Directory not empty. If you have access to bash shell, try to run command: rmdir /var/sam/www/webtop/sandbox/files_d/p1_d/

Conditions:
The sandbox directory corresponding to the partition that you are deleting cannot be removed due to any reason such as Not Existing, Not Empty, etc. on the secondary blade. This can occur on the secondary blades if you create a partition before provisioning APM, then delete the partition on the primary blade, and auto-sync is enabled in the device group.

Impact:
Secondary MCPD exits and blade restarts. Tmm can core. Traffic disrupted while tmm restarts.

Workaround:
N/A

Fix:
Fixed such that Secondary MCP will not exit but only log the warning message as the partition is successfully deleted.

578045-5 : The HTTP_PROXY_REQUEST iRule event can cause the TMM to crash if pipelined ingress occurs when the iRule parks

Component: Local Traffic Manager

Symptoms:
The TMM crashes while resuming from a HTTP_PROXY_REQUEST event.

Conditions:
A HTTP_PROXY_REQUEST iRule event parks. Pipelined ingress occurs.

Impact:

577811 : SNMP sysObjectID OID reports ID of blade on VIPRION 2xxx-series platforms

Component: TMOS

Symptoms:
In BIG-IP v11.5.4, the behavior of the SNMP sysObjectID changed for VIPRION 2xxx-series platforms.
On other BIG-IP 10.x and 11.x versions running on VIPRION 2xxx-series platforms, the SNMP sysObjectID reports the ID of the Chassis (BIG-IPVprC2400 or BIG-IPVprC2200).
In BIG-IP v11.5.4 and v12.0.0 and later running on VIPRION 2xxx-series platforms, the SNMP sysObjectID reports the ID of the Blade (BIG-IPVprB2100, BIG-IPVprB2150, or BIG-IPVprB2250).

In all versions of BIG-IP running on VIPRION 4xxx-series platforms, the SNMP sysObjectID reports the ID of the Blade (BIG-IPPb100, BIG-IPPb100n, BIG-IPPb200, BIG-IPPb200N, BIG-IPVprB4300 or BIG-IPVprB4300N).
In BIG-IP v12.0.0 and later running on VIPRION 2xxx-series platforms, the BIG-IP design is changed such that the SNMP sysObjectID reports the ID of the Blade (BIG-IPVprB2100, BIG-IPVprB2150, or BIG-IPVprB2250), consistent with VIPRION 4xxx-series platforms.
[See Solution article for ID 425331, when published.]

Conditions:
VIPRION C2400 and C2200 chassis
VIPRION B2100, B2150 and B2250 blades
BIG-IP v11.5.4 (release)

Impact:
SNMP queries to identify VIPRION 2xxx-series platforms return the Blade ID instead of the Chassis ID, requiring changes in how the returned sysObjectID is interpreted.

Workaround:
Identify a VIPRION 2xxx-series platform by the appropriate Blade ID (BIG-IPVprB2100, BIG-IPVprB2150, or BIG-IPVprB2250), instead of by the Chassis ID (BIG-IPVprC2400 or BIG-IPVprC2200).

Fix:
On VIPRION 2xxx-series platforms, the SNMP sysObjectID OID reports the ID of the Chassis, to match the behavior on VIPRION 2xxx-series platforms with previous BIG-IP versions 10.2.x and 11.x.

Behavior Change:
On VIPRION 2xxx-series platforms, the SNMP sysObjectID OID now reports the ID of the Chassis, to match the behavior on VIPRION 2xxx-series platforms with previous BIG-IP versions 10.2.x and 11.x.

Previously, SNMP sysObjectID reported the ID of the Blade on VIPRION 2xxx-series platforms, to match the behavior on VIPRION 4xxx-series platforms.

576314 : SNMP traps for FIPS device fault inconsistent among versions.

Component: Local Traffic Manager

Symptoms:
The snmp traps bigipFipsDeviceError and bigipFipsFault are inconsistent among versions.

Conditions:
This trap is raised if the FIPS device firmware has stopped responding to requests and is no longer functional. The trap is different on the BIG-IP 10350 FIPS platform.

Impact:

BIGIP-COMMON-MIB::bigipFipsDeviceError .1.3.6.1.4.1.3375.2.4.0.152
This trap means "Encountered error in the FIPS card operation" on all FIPS platforms

BIGIP-COMMON-MIB::bigipFipsFault .1.3.6.1.4.1.3375.2.4.0.156 (from v11.5.4-hf1 and 11.6.1, not 12.0.0)
BIGIP-COMMON-MIB::bigipFipsFault .1.3.6.1.4.1.3375.2.4.0.166 (from v12.1.0)
These traps mean "The FIPS card is currently in faulty state" for the specific FIPS hardware included on the BIG-IP 10350

574153-3 : If an SSL client disconnects while data is being sent to SSL client, the connection may stall until TCP timeout.

Component: Local Traffic Manager

Symptoms:
If an SSL connection gracefully begins to disconnect at the same time as data is being encrypted by SSL acceleration hardware, the connection will remain open until the TCP profile timeout occurs instead of being closed immediately. This can cause unwanted higher memory usage, possibly causing crashes elsewhere.

Conditions:
* A virtual server with ClientSSL or ServerSSL profile.
* BIG-IP SSL acceleration hardware.
* While an SSL record is being encrypted by SSL accelerator hardware, the SSL connection begins to close by client TCP FIN or by any iRule command that closes the connection.

Impact:
There is a potential for higher memory usage, which in turn may cause TMM crash due to memory exhaustion resulting in service disruption.

Workaround:
If the affected SSL traffic does not include any long idle periods, memory consumption can be mitigated by reducing the idle timeout of the TCP or SCTP profile.

Fix:
SSL connections now disconnect normally if a disconnect attempt occurs while data is being encrypted by SSL acceleration hardware.

---

574116-3 : MCP may crash when syncing configuration between device groups

Component: TMOS

Symptoms:
mcpd on the sync target crashes when syncing configuration.

Conditions:
This can occur when a local non-synced object references an object that is synced (such as a local-only virtual server referencing a synced iRule), and a non-synced object on the target machine happens to be referencing the same synced object. In this condition, mcpd could crash if objects in a sync group are deleted and synced.

Impact:
Outage due to mcp crash which causes tmm to restart.

Workaround:
When you have devices with local-only resources that are referencing objects contained in a sync/failover group, avoid deleting any objects (such as iRules) that might be referenced by other local-only resources on other devices. Instead of a "this object is in use error", mcpd on the target machine will crash.

Fix:
Verify existence of rule objects when validating configuration.

572563-4 : PWS session does not launch on Internet Explorer after upgrade

Component: Access Policy Manager

Symptoms:
Internet Explorer (IE) gets stuck entering Protected Work Space (PWS).

Conditions:
One of the DLLs provided by APM, vdeskctrl.dll, provides COM services. IE consumes the COM services. The DLL is loaded by IE during upgrade of PWS components. Intermittently, (especially on slow systems), IE does not unload the old DLL promptly after upgrading PWS. When COM services are invoked to initialize PWS after upgrade, the old DLL provides the service.

572272-3 : BIG-IP - Anonymous Certificate ID Enumeration

Solution Article: K65355492

---

572234-4 : When using a pool route, it is possible for TCP connections to emit packets onto the network that have a source MAC address of 00:98:76:54:32:10.

Component: Local Traffic Manager

Symptoms:
When using a pool route, it is possible for TCP connections to emit packets onto the network that have a source MAC address of 00:98:76:54:32:10. This is the MAC address of Linux's tmm0 or tmm interface.

Conditions:
The traffic destination is the BIG-IP Linux host, e.g. big3d iQuery server.

The traffic is proxied via fastL4, e.g. ConfigSync "Local Address" is set to None.

The return route is a pool route.

The traffic is interrupted, e.g. a router between the iQuery server and the client is switched off for several seconds.

Impact:
The traffic is sourced from invalid ethernet MAC 00:98:76:54:32:10.
The iQuery connection cannot continue.

Workaround:
Increase the lasthop module's TCP idle timeout.

echo 121 > /proc/sys/net/lasthop/idle_timeout/tcp

Fix:
TCP connections no longer emit packets that have a source MAC address of 00:98:76:54:32:10.

Component: Service Provider

Symptoms:
Errors similar to the following in the ltm log:

err tmm3[21915]: 01220001:3: TCL error: /Common/RadiusTest CLIENT_DATA - Buffer error (line 1) (line 1) invoked from within 'RADIUS::avp 26 ip4 index 0 vendor-id 12345 vendor-type 6'.

Conditions:
The issue happens when there is a RADIUS::avp command for a vendor specific AVP and there's a RADIUS request that contains a different vendor-id than what was specified in the iRule command.

Impact:
You are unable to use vendor-specific RADIUS AVP commands

Workaround:
None.

Fix:
Vendor-specific RADIUS AVP commands no longer generate errors.

572133-3 : tmsh save /sys ucs command sends status messages to stderr

Component: TMOS

Symptoms:
When you run the tmsh save /sys ucs command, some normal status messages are being sent to stderr instead of stdout. This will be seen if a you are watching stderr for error messages.

Conditions:
There are no conditions, every time the command is run, it will send some status type messages to stderr.

Impact:
If a script runs the command it may report that the save failed because messages were send to stderr.

Workaround:
You can ignore the message "Saving active configuration..." being sent to stderr. It is not an error.

Fix:
The command will send the status messages to stdout.

571573-3 : Persistence may override node/pmbr connection limit

Solution Article: K20320811

Component: Local Traffic Manager

Symptoms:
In certain circumstances the BIG-IP system may load balance connections to a node or poolmember over the configured connection limit.

Conditions:
- Node or pool member configured with connection limit.
- L4 or L7 virtual server.
- Persistence configured on the Virtual Server.
- Very high load on unit.

Impact:
BIG-IP system may load balance connections to a node or pool member over the configured connection limit.

Workaround:
Remove persistence or use another method of limiting the connections (rate limiting or connection limit on the Virtual Server).

Fix:
The BIG-IP system now correctly enforces the pool member/node connection limit.

571344-2 : SSL Certificate with special characters might cause exception when GUI retrieves items list page.★

Component: TMOS

Symptoms:
After upgrading, unable to view certain certs from gui. Catalina.out file could contain the signature MalformedByteSequenceException: Invalid byte 2 of 3-byte UTF-8 sequence.

iControl SOAP methods
====================
Management::KeyCertificate::get_certificate_list and get_certificate_list_v2 will return an exception if returning a certificate with special characters.

Conditions:
SSL Certificate with special characters might cause exception when GUI retrieves items list page. This has been observed on upgrades to BIG-IP version 11.5.4 through 12.0.0.

Impact:
The GUI does not display the page containing certificate information. iControl SOAP cannot return a list of certificates if they contain information with special characters.

Workaround:
None.

Fix:
The GUI now correctly displays certificates with special characters, and iControl SOAP methods Management::KeyCertificate::get_certificate_list and get_certificate_list_v2 no longer return exceptions.

571210-3 : Upgrade, load config, or sync might fail on large configs with large objects.

Component: TMOS

Symptoms:
Attempting to load a large config with large objects may result in the following error message:

err mcpd[7366]: 01070710:3: Database error (52), Can't write blob data, attribute:implementation status:52 - EdbBlobData.cpp, line 57

Attempting to synchronize a large change may result in the following error messages and a crash of the MCPD process:

err mcpd[8210]: 01071693:3: Incremental sync: Caught an exception while adding a transaction to the incremental config sync cache: unexpected exception.

err mcpd[8210]: 01070734:3: Configuration error: MCPProcessor::processRequestNow: Can't write blob data, attribute:msgs status:52

err mcpd[8210]: 01070596:3: An unexpected failure has occurred, request_group destroyed while processing, exiting...

Conditions:
The config must be approximately 19.75 MB (slightly less) prior to processing a large object in the config that exceeds 256 KB.

Or, once config exceeds 19.75 MB and 2 MB of additional memory has been allocated, processing config objects that exceed 256 KB (the larger, the more likely to occur) lead to the error.

Impact:
Upgrade, load config, or sync might fail, and a system crash and restart might occur.

Workaround:
Stagger the load, or reduce the size of particularly large objects within a config.

Fix:
Memory handling is improved so that large configs with large objects now successfully complete upon upgrade, load config, or sync.

571019-2 : Topology records can be ordered incorrectly.

Component: TMOS

Symptoms:
Topology records can contain missing order numbers, duplicate order numbers, and differences in the ordering of topology records on BIG-IP's in a sync group.

Conditions:
When adding or deleting topology records or modifying the order of existing topology records, the resulting ordering of the topology records can be inconsistent. This can lead to ordering issues including differences in the ordering of topology records on BIG-IP's in a sync group.

Impact:
It is difficult to manage the order of topology records. Topology records are evaluated in different orders on different BIG-IP's in a sync group.

Workaround:
None.

Fix:
Topology records are now ordered consistently.

570640-4 : APM Cannot create symbolic link to sandbox. Error: No such file or directory

Component: Access Policy Manager

Symptoms:
The user may encounter the following configuration error when adding a new APM sandbox-contained object in a non-default partition (other than /Common) if the user has ever attempted (but failed) to delete this partition (for example, couldn't delete it because it was not empty).

01070734:3: Configuration error: Cannot create symbolic link to sandbox. Error: No such file or directory. If you have access to bash shell, try to run command: ln -s /config/filestore/files_d/p1_d/sandbox_file_d /var/sam/www/webtop/sandbox/files_d/p1_d/sandbox_file_d. Then try to upload file again.
Unexpected Error: Validating configuration process failed.

Conditions:
The user has ever attempted (but failed) to delete the partition.

Impact:
No more APM sandbox object such as Hosted-Content can be added to the partition.

Upgrade may fail to install configuration with the impacted sandbox object.

Workaround:
Manually use the shell command 'mkdir -p' to re-create the missing folder where the symbolic link is suppsed to be created as shown in the error message.

Directories are: {to do mkdir -p)

570617-5 : HTTP parses fragmented response versions incorrectly

Component: Local Traffic Manager

Symptoms:
When a fragmented response is parsed by HTTP, the version field may be incorrectly bounded. HTTP correctly determines the version of the response. However, other filters that re-scan the version field might see a truncated value. The filters then miss-parse the HTTP version.

Conditions:
A fragmented response where the HTTP version field appears in multiple packets. Another filter, for example VDI, re-scans the HTTP version field.

Impact:
The detected version of HTTP may be incorrect. Typically, the response is detected as a HTTP/0.9 response rather than the 1.0 or 1.1 response it actually uses.

Workaround:
None.

Fix:
HTTP correctly bounds the response version for other filters to parse.

---

570570-2 : Default crypto failure action is now 'go-offline-downlinks'.

Component: Local Traffic Manager

Symptoms:
Previously, if a crypto accelerator encountered a failure, the default action was "none" or "failover". Now, the default behavior is "go-offline-downlinks".

(Note: You can find information on crypto accelerator fail-safe behavior in K16951: Overview of SSL hardware acceleration fail-safe :: https://support.f5.com/csp/article/K16951.)

Conditions:
Crypto accelerator encounters a failure and crypto.ha.action has not been changed from its default.

Impact:
If a hardware accelerator failed on a blade in a chassis, the system would failover, but if there was a second failover back to the chassis with the failed blade, SSL traffic might get dropped.

Workaround:
Set the db variable crypto.ha.action to your desired value.

Fix:
Previously, if a crypto accelerator encountered a failure, the default action was either 'none' or 'failover'. Now, the default behavior is 'go-offline-downlinks'.

Behavior Change:
The default value of the db variable crypto.ha.action has changed to 'go-offline-downlinks'. The only time this has an effect on the system is when a crypto accelerator fails. For a chassis, this value will cause the blade that had the failed crypto device to go offline, leaving the other blades to handle the load, while an appliance will failover to its standby peer. See https://support.f5.com/csp/article/K16951 for more details.

Conditions:
BIG-IP APM configured and is accessed by Internet Explorer. This can happen after an upgrade of BIG-IP.

Impact:
The prompt should not occur.

Fix:
Internet Explorer will no longer prompt to run InstallerControll.cab

570053-1 : HA peer's certkeychain of clientssl profile is unexpectedly either removed or re-named after config sync.

Solution Article: K78448635

Component: TMOS

Symptoms:
HA peer's certkeychain of clientssl profile is unexpectedly either removed or re-named after config sync.

Conditions:
The issue is seen when all the below conditions are met.
1. When more than one certkeychains are configured in the clientSSL profile.
2. When the content of a certkeychain of the clientSSL profile is modified. For example, "modify ltm profile client-ssl a4 cert-key-chain modify { default { cert rsa.crt key rsa.key } }".
3. Performs config sync in HA setup.

Impact:
Missing certkeychain of a clientSSL profile can result in its inability to handle some kind of SSL traffic. For example, if the clientSSL originally has EC key/cert but loses it, then it is no longer able to handle SSL connection using EC cipher suites.

Workaround:
Basically reconfigure certkeychain but avoid modifying the content.
1. On any BIG-IP system, leave only the RSA certkeychain in the clientSSL profile, just like the default configuration.
2. Config sync, so that both systems have only the RSA certkeychain.
3. In any BIG-IP system, add certkeychains for other types (EC or DSA) you need. You can "add" or "delete" but do not "modify" any existing certkeychain.
4. Do config sync, so that both systems have the same certkeychains in the clientSSL profile.

569972-3 : Unable to create gtm topology records using iControl REST

Component: Global Traffic Manager (DNS)

Symptoms:
The user is unable to create gtm topology records using iControl REST.

Conditions:
This occurs when a user issues an iControl REST POST command for a gtm topology record.

Impact:
The iControl REST POST command fails with the following error: 'Topologies must specify both regions: ldns: server:'.

Workaround:
Use TMSH, iControl SOAP, or the GUI to create gtm topology records.

Fix:
You can now create gtm topology records using iControl REST.

Please be sure to format the gtm topology oid string using the following rules:

1) Use only a single space between each item in the topology string.
2) Use a fully-pathed name for datacenter, isp, region, and pool objects.

For example:
"ldns: subnet 11.11.11.0/24 server: datacenter /Common/DC".

Impact:
Losing old statistics for application security anomalies

Fix:
Upgrade to newer version and verify that old statistics are shown.

---

569718-3 : Traffic not sent to default pool after pool selection from rule

Component: Local Traffic Manager

Symptoms:
If you have an iRule configured to match a pattern in the HTTP::uri and send it to a non-default pool, subsequent requests in the HTTP keep-alive session will also be sent to the non-default pool even though they do not match the iRule.

Conditions:
This occurs after upgrading from 11.5.3 HF1 to 11.5.3 HF2.

Impact:
If the pool members are not configured to accept traffic that doesn't match the uri criterial, the server will not respond properly.

Fix:
Reverted a change that caused subsequent HTTP requests to go to the non-default pool after it was selected in an iRule.

---

569642-3 : Deleting all routes on a unit with a mirroring fastL4 Virtual may cause TMM to core

Component: Local Traffic Manager

Symptoms:
In certain circumstances TMM may core if an HA pair configured with mirroring has all the routes to the server pool removed.

Conditions:
- HA pair.
 - FastL4 VIP with mirroring.
 - default route to pool via an intermediate router.
 - The active unit is handling traffic.
 - Active unit fails over and loses its mirroring connection.
 - Prior active unit comes back and HA connection is reestablished.
 - During the loss of HA and its recovery the now active unit loses its only route to the pool member.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not remove all routes to poolmembers. If this is needed please create other backup routes prior to the deletion.

Fix:
TMM no longer cores on deleting all routes on a unit with a mirroring fastL4 Virtual during HA connection loss and recovery.

---

569521-2 : Invalid WideIP name without dots crashes gtmd.

Component: Global Traffic Manager (DNS)

Symptoms:
If a user creates a WideIP or WideIP Alias with a name that does not contain a dot, gtmd crashes.

The symptom is a crash and core dump from gtmd.

Conditions:
This occurs when the following conditions are met:
-- FQDN validation is suppressed by the following setting: gtm global-settings general domain-name-check == 'none'.
-- User attempts to create a WideIP with a name that does not contain a dot.

Impact:
gtmd crashes and WideIPs do not function.

Workaround:
When creating a WideIP or WideIP Alias while FQDN validation has been disabled (by setting gtm global-settings general domain-name-check == 'none'), make sure that the WideIP or WideIP Alias name contains at least one dot, and follows these rules:
-- The name must not end with a dot.
-- The name must not begin with a dot, unless '.' is the entire name.
-- The name contains no consecutive dots.

Fix:
FQDN now validates to confirm that a WideIP or WideIP Alias name has at least one dot in an appropriate position, and has no consecutive dots, so there is no crash and core dump from gtmd. This validation occurs even when other FQDN validation has been suppressed by setting
gtm globlal-settings general domain name check == 'none'.

Component: Local Traffic Manager

Symptoms:
When net cos (class of Service) feature is enabled, vlan priority for those cmp redirected packets are not being preserved from ingress to egress.

Conditions:
1. net cos feature is enabled
2. packet is being cmp redirected from one tmm to another tmm for processing.

Impact:
Egress packets are not being processed according to the ingress vlan priority by BIG-IP and down stream router. Certain packets will be dropped by downstream router due to the wrong mark of vlan priority.

Workaround:
None.

569288-4 : Different LACP key may be used in different blades in a chassis system causing trunking failures

Component: Local Traffic Manager

Symptoms:
In rare conditions, different blades in a chassis system may use different LACP keys for the same trunk in the LACP control frames. This will cause some of the LACP trunk members not able to aggregate successfully with peer switch.

Conditions:
This only happens in a chassis based system when certain race condition causes trunk id being modified after initial trunk creation.

Impact:
Non aggregated trunk members won't be able to pass traffic.

Workaround:
Restart lacpd in all the blades in the chassis by running command "clsh bigstart restart lacpd"

---

569255-5 : Network Access incorrectly manipulates routing table when second adapter being connected if "Allow Local subnet access' is set to ON

Solution Article: K81130213

Component: Access Policy Manager

Symptoms:
When Network Access is already established and a second network interface is being connected to client system, VPN quickly reconnects, which breaks existing TCP connections. Because reconnect occurs very quickly, it might appear to the user that nothing happened.

Conditions:
-- 'Allow Local subnet access' enabled.
-- Client system is getting second network interface connected.

Impact:
Long-standing TCP connection may break, for example, VPN over Network Access.

Workaround:
Disable 'Allow Local subnet access'.

Fix:
Now Network Access remains stable when a second network interface is being connected, so any long-standing TCP connections (such as VPN over Network Access) continue as expected.

---

569236-2 : BIG-IP logs INVALID-SPI messages but does not remove the associated SAs.

Solution Article: K24331010

Component: TMOS

Symptoms:
The BIG-IP system logs INVALID-SPI messages but does not remove the associated Security Associations (SAs) corresponding to the message.

Note: There are three parts to this issue, as recorded in the following bugs: 569236, 583285, and 662331.

Conditions:
This can occur if an IPsec peer deletes a phase2 (IPsec) SA and does not send a 'notify delete' message to the other peer. The INVALID-SPI message is most likely to be seen when the peer deletes an SA before the SA's agreed lifetime.

Impact:
If the BIG-IP is always the Initiator, the Responder will not initiate a new tunnel if the Responder only handles responses to the BIG-IP clients' traffic. The BIG-IP system continues to use the IPsec SA it believes to be still up. When an SA expires prematurely, some IPsec peers will reject an inbound SPI packet with an ISAKMP INVALID-SPI notify message. If the INVALID-SPI message does not cause new SAs to be created, there will be a tunnel outage until the SA lifetime expires on the defunct SA held on the BIG-IP system.

Workaround:
Manually remove the invalid SA on the BIG-IP system by running the following command:
delete /net ipsec ipsec-sa spi <invalid_spi>

Fix:
Now, when the BIG-IP system receives INVALID-SPI messages, it deletes the invalid Security Association as well as logging the INVALID-SPI message, so the tunnel can initiate again.

Note: There is a three-part fix provided for this issue, as provided in the following bugs: 569236, 583285, and 662331.

568889-5 : Some ZebOS daemons do not start on blade transition secondary to primary.

Solution Article: K22989000

Component: TMOS

Symptoms:
In some specific cases the standby unit's secondary blade ZebOS daemons might not get started when it becomes active.

Conditions:
If the failover occurs as a result of the primary blade's mcpd restarting

Impact:
The new primary blade does not start some ZebOS daemons resulting in ospf not working as expected on the standby unit.

Workaround:
Run the following tmsh command on the new active unit: bigstart restart tmrouted.

Fix:
The BIG_IP system now correctly starts ZebOS daemons on the standby unit on a new blade that is starting up as a primary.

568743-2 : TMM core when dnssec queries to dns-express zone exceed nethsm capacity

Component: Local Traffic Manager

Symptoms:
tmm crashes, and in /var/log/ltm you see entries indicating "Signature failed":

err tmm1[16816]: 01010216:3: DNSSEC: Signature failed (signature creation) for RRSET (host0530.f5test.net, 1) with key /Common/myZSK2, generation 1.

Conditions:
This can occur when a dns-express zone generates more responses than the Thales can sign. The excess requests are queued and tmm can core.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
TMM no longer core when dnssec queries to dns-express zone exceed nethsm capacity.

---

568543-2 : Syncookie mode is activated on wildcard virtuals

Component: Local Traffic Manager

Symptoms:
Syncookie mode can be activated with a wildcard virtual, even in the case where there is no SYN flood.

Conditions:
The default number of connections per second before activating syncookie mode is 1993. This value can be increased to a max of 4093. After this threshold is reached, then syncookie mode is activated. This is an insufficient maximum for wildcard virtuals, since they can have 30k+ connections per second.

Impact:
Syncookie mode is activated with high connection rates to a wildcard virtual.

Workaround:
Break up the wildcard virtual into multiple virtuals to reduce the number of connections per virtual.

Fix:
It is now possible to set the PvaSynCookies.Virtual.MaxSynCache DB variable to 64K (previous max was 4093)

565534-3 : Some failover configuration items may fail to take effect

Solution Article: K40254066

Component: TMOS

Symptoms:
These symptoms apply to version 12.0.0 and later:

When only multicast failover is configured, traffic-groups are active on all devices in the device-group. If unicast failover is also configured, the traffic-group unexpectedly switches to a different device.

These symptoms can occur on all versions:

When the unicast address list is changed at the same time as other device properties, sod (the failover daemon) may fail to recognize one of the other changes.

Conditions:
For version 12.0.0 and later:

Multicast failover is configured and the system loads the configuration from the configuration files. For example during the first boot of a new boot location, or after performing the procedure in K13030: Forcing the mcpd process to reload the BIG-IP configuration https://support.f5.com/csp/article/K13030.

For all versions:

A change is made to the cm device configuration that includes a unicast-address change along with something else.

Impact:
When only multicast failover is configured, traffic-groups may become active on all devices in the device-group. If unicast failover is also configured, the traffic-group might switch to a different device.

Workaround:
Mitigation for v12.0.0 (and later) symptom:

To restore multicast failover, disable and re-enable multicast failover.

To do so, perform the following procedure on the the local device.
1. Determine which interface is being used for multicast failover by running the following tmsh command:
list cm device device1 multicast-interface.
3. Disable and re-enable multicast failover by running the following tmsh commands:
modify cm device device1 { multicast-interface none }.
modify cm device device1 { multicast-interface eth0 }.


Mitigation for all versions symptoms:
Do not make cm device unicast-address changes simultaneously with changes to other cm device properties.

Fix:
With the fix, sod now sends out multicast FO heartbeat datagrams under the same condition.

macro name "empty"

Impact:
Rare case, but the import of such a policy may fail.

Workaround:
One of the objects could be renamed in the bigip.conf file to avoid such a naming pattern.

Fix:
Objects are being exported correctly without error.

563475-1 : ePVA dynamic offloading can result in immediate eviction and re-offloading of flows.

Solution Article: K00301400

Component: TMOS

Symptoms:
ePVA dynamic offloading can result in immediate eviction and re-offloading of flows. If dynamic offloading is enabled in the fastl4 profile, flows that collide in the ePVA will ping/pong in and out of the ePVA due to immediate eviction and re-offloading. Flows that are evicted due to collisions are reported in the epva_flowstat stats, tot.hash_evict.

Conditions:
A fastl4 profile with PVA Offload Dynamic enabled and two flows that result in a hash collision, resulting in an evicted flow.

Impact:
Flows that collide will be re-offloaded, evicted, and then re-offloaded again within a short time span. It is unknown if there is a direct impact, but in some cases a delay in processing packets on a connection may occur.

Workaround:
Disable PVA Offload Dynamic in the fastl4 profile. Another option would be to disable PVA Flow Evict in the fastl4 profile.

Fix:
The system now handles flows involved in hash collisions such that ePVA dynamic offloading no longer results in immediate eviction and re-offloading of flows.

---

562921-2 : Cipher 3DES and iQuery encrypting traffic between BIG-IP systems

Component: Global Traffic Manager (DNS)

Symptoms:
BIG-IP systems use the iQuery protocol to securely communicate with other BIG-IP systems. The BIG-IP system supports the AES/3DES ciphers for encrypting iQuery traffic. Some of these ciphers are now considered unsecure.

Conditions:
The value is hardcoded into the product.

Note: This is completely independent of the TMM profiles or the httpd cipher values.

Impact:
There is no way to configure this; the value is hardcoded. Scanner operations performed on your configuration will report this as an unsecure cipher.

Workaround:
If you do not need iQuery at all, you can block port 4353 completely. For those who do need it, there is no workaround.

Fix:
The cipher list in use is now
"AESGCM:AES:!ADH:!AECDH:!PSK:!aECDH:!DSS:!ECDSA:!AES128:-SHA1:AES256-SHA"

561348-2 : krb5.conf file is not synchronized between blades and not backed up

Component: Access Policy Manager

Symptoms:
krb5.conf file is not in sync across all blades.
this may cause a feature (Kerberos SSO / Kerberos Auth) to not work as expected.

Conditions:
When administrator made changes to krb5.conf file manually, the configuration file is not synchronized to all blades or is lost upon upgrade.

Impact:
Kerberos Auth / Kerberos SSO does not work properly on all blades.

Workaround:
None.

Fix:
The APM code now automatically synchronizes the changes to /etc/krb5.conf file to all devices in the Failover Device group. Any change made to this file either in Active Device or Standby device will be automatically synced to other device.

In Chassis, all the Secondary blades will mirror the file on the Primary blade. Any manual change done on the Secondary blade(s) will be lost. The admin has to do the changes on Primary blade only and it will be synchronized with all others blades.

Behavior Change:
When admin modifies /etc/krb5.conf file, the changes are automatically updated on other devices in the same Failover Device group.

When admin modifies the /etc/krb5.conf file on the primary blade of the chassis, the changes are automatically updated on all secondary blades.

- MCPD is not in the running state.
 - DHCP is enabled.
 - DHCP server has provided multiple domain-name-server entries in the lease.

Impact:
Domain name resolution doesn't work.

Workaround:
Bring up MCPD which would write the resolv.conf in the correct format. Alternatively, user can manually modify /etc/resolv.conf to write multiple nameserver entry one per line.

Fix:
DHCP will now write a single nameserver per line in /etc/resolv.conf when multiple nameservers are configured in DHCP.

560405-5 : Optional target IP address and port in the 'virtual' iRule API is not supported.

Component: Local Traffic Manager

Symptoms:
In certain scenarios there is a need to redirect an HTTP request through a given virtual server to a another virtual server (or remote endpoint). Such an operation is also known as 'vip-to-vip' forwarding. The available iRule API (specifically, the 'virtual' command) does not currently support this functionality.

Conditions:
Using an iRule to forward a request through a given virtual server to another virtual server or remote endpoint.

Impact:
Cannot implement HTTP Forward Proxy plus Transparent redirection to Web-Cache Pool.

Workaround:
None.

Behavior Change:
The 'virtual' iRule API has been changed to support a secondary target IP address and port to redirect the connection to, from a given virtual server. The new signature of the 'virtual' iRule API is:

virtual [<name>] [<ipaddr> [<port>]]

where:

-- <name> = the name of the virtual server to redirect the connection from.
-- <ipaddr> = the target IP address of the remote endpoint to route the connection to, through the specified virtual server; <ipaddr> can also have a route-domain (%).
-- <port> = the port of the remote endpoint to route the connection to, through the specified virtual server.

558858-1 : Unexpected loss of communication between slots of a vCMP Guest

Solution Article: K80079953

Component: TMOS

Symptoms:
1. Within the vCMP guest, the affected slot shows the other slot(s) to be offline. When logged into any other "offline" slot, the slot shows itself to be online.

2. Within the vCMP guest, on the affected slot, the log files (such as /var/log/ltm) have stopped recording log entries from the other slot(s).

3. Within the vCMP guest, on the affected slot, the eth1 interface shows TX increasing but RX not increasing. The eth1 interface on other slots shows both TX and RX increasing.

Conditions:
Only affects vCMP guests with 2 or more slots on VIPRION C2000-series chassis.

Impact:
The number of working slots in a vCMP guest is reduced to 1 slot. The effect on traffic may range from none to severe.

Workaround:
Within the vCMP guest, login to the command line (vconsole or SSH) of the affected slot and run the following:

ifconfig eth1 down ; ifconfig eth1 up

Alternatively, from the hypervisor, modify the vCMP guest to the Configured state, and wait to confirm the vCMP guest has stopped on all slots. Then return the vCMP guest to the Deployed state.

Fix:
This release no long exhibits loss of communication between slots of a vCMP Guest.

558573-3 : MCPD restart on secondary blade after updating Pool via GUI

Solution Article: K65352421

Component: TMOS

Symptoms:
If you use the LTM GUI in a clustered environment to add an IP Encapsulation profile to a Pool, then click Update, mcpd and other daemons may restart on secondary blades in the cluster.

When this occurs, errors similar to the following will be logging from the secondary blades:
-- err mcpd[22537]: 01020036:3: The requested pool profile (49825) was not found.
-- err mcpd[22537]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020036:3: The requested pool profile (49825) was not found.

Conditions:
This problem may occur when operating BIG-IP in a clustered environment (VIPRION), and using the GUI to update the properties of an LTM pool with an IP Encapsulation profile defined.

Impact:
Daemon restarts, disruption of traffic passing on secondary blades.

Workaround:
Perform pool updates via the tmsh command-line utility.

Fix:
Pool profile update is performed by name rather than object ID, so MCPD no longer restarts on secondary blade after updating a pool using the GUI.

---

557783-3 : TMM generated traffic to external IPv6 global-addr via ECMP routes might use link-local addr

Solution Article: K14147369

Component: Local Traffic Manager

Symptoms:
TMM might use a link-local IPv6 address when attempting to reach an external global address for traffic generated from TMM (for example, dns resolver, sideband connections, etc.).

Conditions:
- ECMP IPv6 routes to a remote destination where the next hop is a link local address. Typically this occurs with dynamic routing.
- Have configured a virtual server that generates traffic from TMM (for example, dns resolver, sideband connections, etc.).

Impact:
Traffic might fail as its egresses from a link-local address instead of a global address.

Workaround:
It might be possible to work around if the dynamic routing peer can announce the route from a global address instead of a link local.
Use of static routes might also work around the issue.

Fix:
TMM now uses the correct IPv6 global address when generating traffic to a remote address using ECMP routes via link-local next-hops.

557645-1 : Communication between devices in a high availability (HA) configuration might occasionally fail on VIPRION 2200 and 2400 platforms.

Component: Local Traffic Manager

Symptoms:
Communication between devices in a high availability (HA) configuration might occasionally fail on VIPRION 2200 and 2400 platforms.

Conditions:
VIPRION 2200 and 2400 platforms with more than one blade.

Multiple devices in an HA configuration.

TMM incorrectly identifies which TMM should handle host connections from an HA peer.

The host connection will be reset after the SYN retransmits are exceeded between TMM and the host process.

Impact:
Periodic reported failures in host-to-host communication. This could affect config sync, and other HA related communication.

Workaround:
None.

Fix:
Host communication on VIPRION 2200 and 2400 platforms behaves the same as host communication on non-VIPRION 2200 and 2400 platforms, as expected.

---

557281-3 : The audit_forwarder process fails to exit normally causing the process to consume CPU to near 100%

Component: TMOS

Symptoms:
audit_forwarder and mcpd consume almost 100% CPU. When syslog-ng restarts, it starts another audit_forwarder process, but it is the orphaned audit_forwarder process that will consume almost 100% CPU. When syslog-ng is restarted and audit_forwarder does not exit cleanly, the mcpd process will also begin consuming high CPU.

Conditions:
syslog-ng is stopped manually or sometimes (rarely) during a normal restart of syslog-ng.

Impact:
The audit_forwarder and mcpd processes consume excessive CPU.

Workaround:
Stop audit_forwarder manually (kill -9), once the orphaned audit_forwarder process is stopped, mcpd will return to normal CPU consumption.

Fix:
When syslog-ng is stopped manually (or when expected), audit_forwarder also exits, so the audit_forward process no longer consumes increasing CPU.

557221 : Inbound ISP link load balancing will use pool members for only one ISP link per data center

Component: Global Traffic Manager (DNS)

Symptoms:
In BIG-IP Link Controller and GTM 11.5.3, 11.6.0 and prior versions, and BIG-IP DNS 12.0.0, the inbound ISP link load balancing functionality uses pool members for more than one ISP link per data center.

Conditions:
Using the inbound ISP link load balancing functionality in BIG-IP Link Controller and GTM 11.5.3, 11.6.0 and prior versions, and BIG-IP DNS 12.0.0.

Impact:
If a pool has multiple members that use different ISP links within a data center, the system uses only pool members associated with the ISP link of the first available pool member. The system marks pool members associated with subsequent ISP links as unavailable (grey).

Fix:
The inbound ISP link load balancing functionality will use pool members for only one ISP link per data center for each pool.

Behavior Change:
Beginning in BIG-IP Link Controller and GTM 11.5.4, 11.6.1, and BIG-IP DNS 12.1.0, the ISP link load balancing functionality will use pool members for only one ISP link per data center for each pool.

The link that is associated with the first configured and available pool member within each data center will determine the link that will be used for the data center. The system will use only pool members associated with that link.

557062-3 : The BIG-IP ASM configuration fails to load after an upgrade.★

Component: Application Visibility and Reporting

Symptoms:
A configuration load failure occurs after creating an ASM predefined report in a previous version - (11.3 or 11.4) and upgrading to a version prior to 12.1.0.

Conditions:
Define scheduled report with 'predefined-report-name: '/Common/Top alerted URLs' on version 11.3 or 11.4 upgrade the version.

Impact:
Version upgrade fails (the BIG-IP system becomes unusable).

Workaround:
Manually change predefined-report-name '/Common/Top alerted URLs' to predefined-report-name '/Common/Top alarmed URLs'.

Fix:
If an ASM predefined report was created in a previous version and the system was updated, it could have caused the configuration upgrade to fail. This failure no longer occurs.

---

556694-6 : DoS Whitelist IPv6 addresses may "overmatch"

Component: Advanced Firewall Manager

Symptoms:
When using the 8-entry "rich" DoS whitelist with IPv6 addresses, the HW matches only 32 bits of an incoming IPv6 address against the whitelist entry, meaning that if an incoming IPv6 address matches those 32 bits, the whitelist will result in "match", even if other bits of the IPv6 address do not match.
Note that the configuration can select which set of bits (there are 4 choices -- 127:96, 95:64, 63:32, 31:0) to match against, via the db.tunable dos.wlipv6addrsel.
Also, note that IPv4 matches are always perfect, and are not affected by this issue.

Conditions:
Occurs when the 8-entry AFM DoS Whitelist is used to match against IPv6 addresses.

Impact:
In some cases, the Whitelist may overmatch, meaning some IPv6 addresses will be considered whitelist matches, when they do not match the whitelist.

556560-1 : DNS messages may become malformed if the Additional section contains an OPT record followed by multiple records.

Solution Article: K80741043

Component: Local Traffic Manager

Symptoms:
A DNS message may become malformed when its Additional records section contains an OPT record followed by multiple other DNS records.

As a result of this issue, you may encounter the following symptom:

The BIG-IP system receives properly formed DNS packets but after processing them sends them as malformed DNS packets.

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

-- Your BIG-IP configuration contains a virtual server with an associated DNS profile.
-- The BIG-IP system receives a DNS message that contains an OPT record.
-- The DNS message's Additional records section contains multiple other DNS records.

Impact:
This issue impacts all DNS messages that contain an OPT record followed by more than one record. The DNS handling code expects a message containing an OPT record to have 0 or 1 TSIG record following the OPT record in the additional record section of a message.

The RFCs permit the OPT record to be placed anywhere in the additional record section of a DNS message, with the exception of a TSIG record. If a TSIG record is present, it must always be last. If no TSIG record is present, then an OPT record can be last.

The RFCs do not restrict a query from containing records in the additional record section of the message.

When a DNS query or response is passed through the TMM DNS message handler, and that message contains an OPT record followed by more than one record, and those records that follow the OPT record contain compression pointers to other records that also follow the OPT record, then the message becomes mangled.

Workaround:
Disable DNS compression on the resolver, or configure the resolver to place OPT records at the end of the additional section (except TSIG records which must always be last).

Fix:
DNS messages which contain a record other than TSIG following an OPT record in the additional record section will be transformed in the message handler and the message inspection will be restarted.

The transformation involves safely moving the OPT record to be last or second-to-last (in the presence of a TSIG record) position of the additional record section. 'Safely' means updating the relevant compression pointers.

The subsequent code paths which depend on the OPT record's position now work as expected.

556380-3 : mcpd can assert on active connection deletion

Component: TMOS

Symptoms:
When all of the peers in an HA / DSC configuration are removed, then it is possible for the connection tear down to result in an assert.

Conditions:
Removal of all peers while a connection is handling a transaction.

Impact:
MCPD asserts and restarts.

Workaround:
No workaround is necessary. MCPD restarts.

Fix:
Connection tear down checks for active connections and does not result in an assert when removing all peers while a connection is handling a transaction.

556284-3 : iqsyncer: GTM/LC config sync failure with error from local mcpd Monitor parent not found

Solution Article: K55622762

Component: TMOS

Symptoms:
GTM/LC config sync fails with error in /var/log/gtm and /var/log/ltm similar to the following:
Monitor /Common/my_http_monitor parent not found

Conditions:
There is a customized GTM monitor on one member of a high availability configuration, but not on others.

Impact:
Config sync fails. On the device that does not have the monitor, the system logs a parent-not-found message into /var/log/gtm.

Workaround:
None.

Fix:
GTM/LC sync now completes successfully even when the configuration being sync'd contains a custom GTM/LC monitor definition.

---

556277-4 : Config Sync error after hotfix installation (chroot failed rsync error)★

Component: TMOS

Symptoms:
Once an installation has been booted into, applying a hotfix over that installation does not change the SELinux policy, but instead uses the previously installed SELinux policy.

Conditions:
This affects installations of a later hotfix atop an earlier hotfix, or onto a base build of the same software version. Installation onto a new volume is unaffected.

To determine whether the configuration will experience this issue, use md5sum to see whether the following have the same checksums:
-- /etc/selinux/targeted/modules/active/modules/f5_mcpd.pp
-- /usr/share/selinux/targeted/f5_mcpd.pp.

If the checksums are the same, the system will use the SELinux policy installed with the previous hotfix, and this issue will occur.

Impact:
Sync of file objects might fail with an error similar to the following:

01071488:3: Remote transaction for device group [name] to commit id [number] failed with error 01070712:3: Caught configuration exception (0), verify_sync_result:() :Failed to sync files. - sys/validation/FileObject.cpp, line 6276..

Workaround:
Instead of installing the hotfix over an existing installation of the base build of that version (or an earlier hotfix), install the base ISO (for example 11.5.4) into a volume, and then install the hotfix onto that volume, without booting the volume in between.

Fix:
Installing a hotfix over an existing base install now rebuilds the SELinux policy as expected.

556252 : sysGlobalTmmStatTmUsageRatio5s and sysGlobalTmmStatNpus in chassis

Component: TMOS

Symptoms:
The sysGlobalTmmStatTmUsageRatio5s and sysGlobalTmmStatNpus OIDs read lower than expected given the traffic on the system. The values suddenly increase when a non-running blade is powered down.

Conditions:
This occurs on a chassis where one or more of the blades are not in the cluster, but are not powered down. The usage ratios and Npus stats treat the blades as if they are in the cluster, and are factored into the calculation, making them appear lower than they actually are because non-working blades are in the calculation.

Impact:
Misleading, confusing statistics

Workaround:
You can completely power down the blade and it will be removed from the statistics calculation.

Fix:
sysGlobalTmmStatTmUsageRatio5s and sysGlobalTmmStatNpus are now calculated only against running blades.

556117-1 : client-ssl profile is case-sensitive when checking server_name extension

Component: Local Traffic Manager

Symptoms:
The client-ssl profile is Case-Sensitive when configuring server-name in the client-ssl profiles and checking server_name extension in the ClientHello Message.

Conditions:
When using mixed upper-lower case server-name in the client-ssl profile configuration and ClientHello messages.

Impact:
The system treats mixed upper-lower case server-name as different names which violate the RFC6066, which states: "Currently, the only server names supported are DNS hostnames. DNS hostnames are case-insensitive."

Workaround:
1. Configure only one client-ssl profile with same server-name.

2. Use only lower-case server-name when configure the client-ssl profile.

3. Use lower-case server-name in the Client side.

Fix:
The system now treats mixed upper-lower case server-names as the same name, so server-name is no longer case sensitive.

If a reachable device is removed from the failover group, no "Disconnected" message is issued, so the last reported status will be inaccurate.

When a device is part of a trust, sod logs messages indicating what unicast addresses it is monitoring on remote devices:

Nov 2 11:34:29 BIGIP-1 info sod[5716]: 010c007a:6: Added unicast failover address 10.145.192.5 port 1026 for device /Common/BIGIP-3.localdomain.

If devices are removed from the trust, sod does not log a message that those unicast addresses are no longer in use.

Conditions:
When a device is removed from a failover device group, or removed from a device trust.

Impact:
Inaccurate state reporting.

Fix:
When a device is removed from a failover device group, it is now reported as "Disconnected".

When a device is removed from the device trust, sod on the other devices correctly reports that the unicast addresses belonging to the other devices have been deleted.

555686-2 : Copper SFPs OPT-0015 on 10000-series appliance may cause interfaces to not come up and/or show corrupted serial numbers

Component: TMOS

Symptoms:
Some OPT-0015 copper small form-factor pluggable (SFP) transceiver might cause an internal bus to hang.

Conditions:
This happens only when the following conditions are met:
-- 10000-series appliances.
-- At reboot, at a restart of the bcm56xxd daemon, or when a copper SFP is enabled or disabled.
-- There is at least one copper SFP present in the appliance.
-- Interfaces are spread between hardware muxes. That means some SFPs are in ports 1.1-1.8 and other SFPs are in ports 1.9-1.16.

Impact:
Corrupted serial number information from SFPs, and fiber SFPs may not come up. Enable and disable of copper SFPs may not work.

Workaround:
None.

Fix:
The system now ensures that the I2C bus muxes only enable a single interface, so the issue with interfaces on Copper SFPs OPT-0015 on 10000-series appliances no longer occurs.

555432-2 : Large configuration files may go missing on secondary blades

Component: Local Traffic Manager

Symptoms:
bigip.conf or other configuration files may go missing on secondary blades once the configuration exceeds a certain size (approximately 8 MB).

Conditions:
This is only relevant on chassis.

Impact:
If the primary changes, then the configuration is at risk of being lost.

Workaround:
touch the relevant configuration file (usually bigip.conf) and the configuration file will reappear.

Fix:
bigip.conf or other configuration files would go missing on secondary blades once the configuration exceeded a certain size (approximately 8 MB). This has been fixed.

555272-3 : Endpoint Security client components (OPSWAT, EPSEC) may fail to upgrade★

Component: Access Policy Manager

Symptoms:
Previously, F5 Client components were signed using SHA1 certificate. SHA1 is now considered insecure and Windows will reject components signed using a SHA1 certificate after March 31st 2016.

To support this new requirement, F5 has changed the client component signing certificates to utilize a higher security validation algorithm.

The result of this change is that clients utilizing client components built prior to these versions:

Big-IP 12.0.0HF1 or earlier
Big-IP 11.6.0 HF8 or earlier
Big-IP 11.5.4 (base release) or earlier

cannot Endpoint Security updates build 431 or greater.

If you require updated Endpoint Security (OPSWAT / EPSEC) builds greater than 431 you must upgrade to these versions:

Big-IP 12.1.0 or later
Big-IP 12.0.0HF2 or later
Big-IP 11.6.1 or later

Big-IP 11.5.4 HF1 or later

Conditions:
Running incompatible BIG-IP version with EPSEC build 431 or later.

Impact:
User will see certificate warnings and installation of client component updates may fail. The failure may occur multiple times.

Workaround:
Upgrade BIG-IP to the correct version.

Use the BIG-IP Web GUI's Software Management :: Antivirus Check Check Updates section to install an EPSEC build prior to 431.

Fix:
Updated signing certificate to a sha256 certificate. Client components and EPSEC binaries are now signed using the new, higher security certificate. Please note that upgrade to a HF in which client is signed using updated certificate is needed to install updated EPSEC releases. Please review the information carefully.

555057-1 : ASM REST: Removing a Signature Set From One Security Policy Removes It From All Security Policies.

Component: Application Security Manager

Symptoms:
When using ASM REST to remove a signature set association from a policy (DELETE), the set is removed from all policies in the system.

Conditions:
ASM REST is used to remove a signature set association from a policy.

 DELETE /mgmt/tm/asm/policies/<ID>/signature-sets/<ID>

Impact:
All policies will lose their association to that signature set. This may leave some policies not enforcing all the Attack Signatures that they are expected to.

Workaround:
A DELETE can be issued to the collection endpoint: /mgmt/tm/asm/policies/<ID>/signature-sets utilizing the $filter parameter to delete only the desired sets.

Ex. DELETE /mgmt/tm/asm/policies/<ID>/signature-sets?$filter=id eq '<ID>'

Fix:
When using ASM REST to remove a signature set association from a policy (DELETE), the signature set association is removed only from the desired policy and not from all policies in the system.

555039-1 : VIPRION B2100: Increase egress traffic burst tolerance for dual CoS queue configuration

Solution Article: K24458124

Component: TMOS

Symptoms:
There is a high drop counts when running tmsh show net interface, and running tmctl -a drop_reason shows that a large number of drops are due to counters.rx_cosq_drop

Smaller buffering alpha values are configured for egress buffering to allow an 8 HW CoS queue feature to correctly implement weight based egress dropping. This results in busy ports dropping more aggressively, although allowing more fair buffering amongst multiple active ports.

Conditions:
Higher traffic rates, which stress switch MMU buffering resources, might result in egress CoS queue drop on busy ports.
This affects the BIG-IP 5000- and 7000 series platforms, and VIPRION B2100, B2150, and PB200 blades.

Impact:
This results in busy ports dropping more aggressively. Note that using smaller values allows more fair buffering amongst multiple active ports, whereas higher values allow better burst absorption but less fair buffering.

Workaround:
None.

Fix:
This release uses a larger alpha value for better burst absorption when the 8 hardware CoS queue feature is not enabled.

---

555006-1 : ASM REST: lastUpdateMicros is not updated when changing a Custom Signature

Component: Application Security Manager

Symptoms:
The lastUpdateMicros field is meant to be updated if a user changes a custom signature, but it is not.

Conditions:
REST client is used to look at/filter the signatures collection (/mgmt/tm/asm/sigantures)

Impact:
Checking for updated signatures does not return the expected result.

Workaround:
None.

Fix:
REST: The lastUpdateMicros field is now correctly updated after updating a user defined signature.

---

554993-1 : Profile Stats Not Updated After Standby Upgrade Followed By Failover

Component: Access Policy Manager

Symptoms:
1. The current active sessions, current pending sessions, and current established sessions counts shown in commands 'tmsh show /apm profile access' and 'tmctl profile_access_stat' become zero after failover.
2. The system posts an error message to /var/log/apm:
01490559:3: 00000000: Access stats encountered error: SessionDB operation failed (ERR_NOT_FOUND).

Conditions:
This issue happens when the following conditions are met:
1. The HA configuration is running a release prior to 11.5.3 HF2, 11.6.0 HF6, or 12.0.0.
2. A standby unit is upgraded to version 11.5.3 HF2, 11.6.0 HF6, or 12.0.0.
3. Failover is triggered.

Impact:
The current active sessions, current pending sessions, and current established sessions counts of profile access stats remain zero after failover.

Workaround:
Upgrade all devices in the HA configuration to the same release and reboot them simultaneously.

Fix:
The current active sessions, current pending sessions, and current established sessions counts of profile access stats now report correctly after failover.

Conditions:
Certain types of failed SSL handshakes in versions 11.5.0 through 11.5.4.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Modifying serverssl cipher string to exclude ECDHE_RSA and ECDHE_ECDSA might help prevent the crash.

Fix:
This release fixes a TMM crash that might be encountered during the SSL handshake.

---

554967-2 : Small Client EDNS0 Limits can Sometimes Truncate DNSSEC or iRule DNS Packets

Component: Local Traffic Manager

Symptoms:
A resolver sending a query with a small EDNS0 UDP buffer limit can lead to packet truncation. These response packets are flagged as truncated in the header, but the OPT record might be cut/missing leading some resolvers to consider the packet malformed.

Conditions:
Primarily via dynamic settings such as iRules on DNS_RESPONSE events adding new records, or DNSSEC record signing with responses over UDP.

Impact:
Some resolvers regard OPT-less truncated packets as malformed and cease follow-up requests via TCP or a larger EDNS0 UDP limit.

Workaround:
none

Fix:
Truncated DNSSEC or iRule DNS packets are RFC-compliant.

---

554774-3 : Persist lookup across services might fail to return a matching record when multiple records exist.

Component: Local Traffic Manager

Symptoms:
Persist lookup across services might fail to return a matching record when multiple records exist.

Conditions:
Persistence profile with 'match-across-services' enabled, and the configuration contains multiple records that correspond to the same pool.

Impact:
Connection routed to unexpected pool member.

Workaround:
None.

Fix:
The operation now continues searching persistence records when 'match-across-services' is enabled until the operation finds a record that corresponds to the same pool.

---

554761-4 : Unexpected handling of TCP timestamps under syncookie protection.

Component: Local Traffic Manager

Symptoms:
The BIG-IP system experiences intermittent packet drops.

Despite being negotiated during TCP handshake, the BIG-IP system fails to present timestamp option in subsequent segments.

The BIG-IP system calculates invalid round trip time immediately after handshake, which might result in delayed retransmissions.

Conditions:
This occurs when the following conditions are met:
- Virtual server configured with a TCP profile with timestamps enabled.

- The syncookie mode has been activated.

- Clients that support timestamps.

Impact:
Connection might be reset by remote TCP stack (e.g., NetBSD and FreeBSD), which requires timestamps to be maintained once negotiated.

Retransmission timeout (RTO) value may be skewed. Segments that are subject to RTO might take up to 64 segments to retransmit.

Workaround:
Choose or create a TCP profile that has timestamps disabled.

Fix:
TCP Timestamps are now maintained on all negotiated flows.

554626 : Database logging truncates log values greater than 1024

Solution Article: K14263316

Component: Access Policy Manager

Symptoms:
The Logging agent truncates log values greater than 1024. If the log value size is greater than 4060, the field is empty or null.

Conditions:
Logging into local database with log values (such as session variables) greater than 1024. If this size is too high (greater than 4060), the field displays as empty or null in reports.

Impact:
The reporting UI displays null or empty fields when the logged value is too large in size, such as a huge session variable.

Workaround:
No workaround.

Fix:
This release handles large single log values.

554563-2 : Error: Egress CoS queue packet drop counted against both Drops In and Drops Out statistics.

Component: TMOS

Symptoms:
Class of Service Queues (cosq) egress drop statistics are counted against both Drops In and Drops Out interface statistics.

Conditions:
This occurs for all cosq drops in response to excess egress traffic and MMU egress congestion.

Impact:
Any CoS queue egress drop is also counted against ingress drop stats, which could be interpreted incorrectly as doubled total drop stats.

Workaround:
None.

Fix:
The Drops In interface statistics no longer includes Class of Service Queues (cosq) egress drop counts, which is correct behavior.

---

554340-2 : IPsec tunnels fail when connection.vlankeyed db variable is disabled

Component: TMOS

Symptoms:
When connection.vlankeyed db variable is disabled, if the data traffic coming out of IKEv1 tunnels that needs to be secured using IKEv2 tunnels lands on tmm's other than tmm0, it will be dropped. The system establishes the IKEv2 tunnel but the data traffic will not be secured.

Conditions:
This issue is seen when the interesting data traffic lands on tmm's other than tmm0. The reason for this issue is due to incorrectly creating a flow on another TMM that is the owner of the outbound SA (IKEv2 tunnel).

Impact:
The system drops the data traffic to be secured using IPsec and connections fail.

Workaround:
Disable the cmp in the virtual server configuration.

Fix:
Flow creation at the TMM that owns the outbound SA for the IKEv2 tunnel is properly handled. TMM can handle the inner traffic from IKEv1 tunnel and secure it over another IKEv2 tunnel.

---

554295-5 : CMP disabled flows are not properly mirrored

Component: Local Traffic Manager

Symptoms:
A client connection to a virtual server configured for 'cmp-enabled no' and 'mirror enabled' will be dropped if the standby unit is promoted to active.

Conditions:
The virtual server is configured for 'cmp-enabled no' and 'mirror enabled' on multiple BIG-IP appliances peered in a high availability configuration.

Impact:
Mirroring does not work as expected on BIG-IP appliances.

Note: CMP is required on VIPRION chassis, so this expectation applies only to appliances.

Workaround:
Do not disable CMP on virtual servers that are mirrored.

Fix:
The system now supports mirroring connections between BIG-IP appliances in a high availability configuration on CMP-disabled virtual servers.

Note: If CMP is disabled, hardware syn cookie must also be disabled for virtual servers to mirror connections. This is expected behavior.

---

554228-4 : OneConnect does not work when WEBSSO is enabled/configured.

Component: Access Policy Manager

Symptoms:
OneConnect is a feature that reuses server-side connections. When WEBSSO is enabled, it always creates a new server-side connection, and doesn't reuse pooled connections.

Conditions:
WEBSSO and OneConnect.

Impact:
Idle serverside connections that should be eligible for reuse by the virtual server are not used. This might lead to build-up of idle serverside connections, and may result in unexpected 'Inet port exhaustion' errors.

Workaround:
None.

Fix:
OneConnect now works when WEBSSO is enabled/configured, so that the system reuses the pooled server side connections.

---

Conditions:
All of the following conditions must apply.
1) Edge Client is installed in "Always Connected" mode.
2) The Connectivity profile on server has location DNS list entries.
3) One of the DNS locations matches the DNS suffix set on the local network adapter.

Impact:
Client shows "LAN Detected" in the UI and does not try to connect to VPN.
All traffic to and from the user's machine is blocked.

Workaround:
This issue has no workaround at this time.

Fix:
Edge Client now ignores DNS location settings in Always Connected mode and establishes VPN even inside enterprise networks.

553795-3 : Differing cert/key after successful config-sync

Component: TMOS

Symptoms:
1) If you change a client-ssl profile to a different cert/key, delete the original cert/key, create a new cert/key with the same name as the original one, associate the new cert/key with the original client-ssl profile, then do a config-sync, the peer system(s)' FIPS chip retains a copy of the original key.

2) If you change a client-ssl profile to a different cert/key, then create a new cert/key with a different name from the original one, associate the new cert/key with the original client-ssl profile, then do a config-sync, the config-sync operation may fail and the peer's client-ssl profile will still use the original cert/key instead of the new one.

Conditions:
1) High Availability failover systems with FIPS configured with Manual Sync.

2) High Availability failover systems without FIPS configured with Manual Sync.

Impact:
1) An abandoned FIPS key is left behind.

2) The systems may be out-of-sync, and one system's client-ssl profile uses one cert/key pair, while the other systems' same client-ssl profile uses a different cert/key pair.

Workaround:
1) For the first scenario, you can use either of the following workarounds:

-- Run an extra config-sync before the second change of the client-ssl profile.
-- Delete the FIPS key by-handle on the peer systems.

2) For the second scenario, you can use the following workaround:
-- Perform another config-sync operation in the GUI with the 'Overwrite Configuration' checkbox checked.

Note: If you also deleted your original cert/key pair, perform the following procedure:

1. Go onto the peer systems.
2. Manually delete those cert/key files that were copied during the first config-sync operation.
3. Look for the corresponding cert/key files in these two directories: /config/filestore/files_d/Common_d/certificate_d: /config/filestore/files_d/Common_d/certificate_key_d:
4. Delete the cert/key files in those directories.

Fix:
Systems now have the same cert/key after successful config-sync of High Availability configurations.

Conditions:
If the SNMP configuration on the BIG-IP changes and the SNMP daemon restarts. This is a timing issue that might appear intermittently.

Impact:
The BIG-IP system stops responding to SNMP requests. You then cannot monitor the BIG-IP system via SNMP.

Workaround:
If the SNMP daemon is locked up, restart it by issuing the following command: bigstart restart snmpd.

Fix:
The SNMP daemon no longer locks up and become unresponsive when it is restarted.

---

553063-4 : Epsec version rolls back to previous version on a reboot

Component: Access Policy Manager

Symptoms:
If administrator has installed multiple EPSEC packages, after a reboot the EPSEC version rolls back to the previously installed version.

Conditions:
The BIG-IP system needs to be rebooted for this issue to be seen, and multiple EPSEC packages must have been installed on the system before the reboot.

Impact:
OPSWAT version rolls back without prompting or logging. This might open up the end-point security issues that are supposed to be fixed by the latest installed OPSWAT package.

Workaround:
The workaround is to upload a dummy file in Sandbox.
1. Go to Access Policy :: Hosted Content :: Manage Files.
2. Upload any dummy file, even a 0 byte file. Change the security level to 'session'.

After this change, even if you reboot or shutdown-restart, the EPSEC version does not revert.

Fix:
The most recently installed EPSEC version now remains configured, and does not roll back after reboot or shutdown-restart.

552931-2 : Configuration fails to load if DNS Express Zone name contains an underscore

Component: Local Traffic Manager

Symptoms:
A configuration with a DNS Express Zone with an underscore in the name does not load, even though the gtm global-settings general domain-name-check is set to any of allow-underscore, svn-compatible, or none.

Conditions:
-- Configuration setting gtm global-settings general domain-name-check is set to any of allow-underscore, svn-compatible, or none.
-- DNS Express Zone exists with an underscore in the name.

Impact:
Cannot load the LTM configuration when restarting BIG-IP system when DNS Express Zones that have an underscore character in the name.

Workaround:
Force the GTM configuration to load by sequentially running the following commands:
tmsh load sys config gtm-only.
tmsh load sys config.

Fix:
All FQDNs may now contain underscore character. The BIG-IP system now correctly load configurations that contain DNS Express Zones with underscores in the name.

552865-5 : SSL client authentication should ignore invalid signed Certificate Verify message when PCM is set to 'request'.

Solution Article: K34035224

Component: Local Traffic Manager

Symptoms:
When peer certificate mode (PCM) is set to request, and the BIG-IP system client-ssl asks for the client certificate, handshake might fail if the client sends an invalid signed Certificate Verify message.

Conditions:
When SSL client certificate mode is request, and the client sends an invalid signed Certificate Verify message to the BIG-IP system.

Impact:
The handshake does not ignore the invalid signed certificate verify message, and handshake might fail. SSL client authentication should ignore invalid signed Certificate Verify message when PCM is set to 'request'. Regardless of whether the Certificate and Certificate Verify message is valid, the handshake should ignore the Certificate Verify signature error and let the handshake continue.

Workaround:
None.

Fix:
When peer certificate mode (PCM) is set to request, and the BIG-IP system client-ssl asks for the client certificate, the handshake now ignores the Certificate Verify signature error and lets the handshake continue. This is correct behavior.

552532-3 : Oracle monitor fails with certain time zones.

Solution Article: K73453525

Component: Local Traffic Manager

Symptoms:
Occasionally, the OJDBC driver reads a time zone file that it cannot understand, which causes Oracle monitors to fail.

Conditions:
- The system uses ojdbc6.jar for Oracle monitor functionality.
- The UTC time zone is configured.
- Contents of the /usr/share/zoneinfo directory are arranged so that the 'UTC' file is not the first in the list. (Versions prior to 10.2.4 use the 1.4-compatible ojdbc14.jar driver. The objdbc6.jar OJDBC driver, as supplied by Oracle for Java 6 (aka 1.6) auto-detects the local system's time zone name by scanning and comparing files under /usr/share/zoneinfo. The filenames are created during installation, and seem to depend on the 'Directory Hash Seed' of the /usr filesystem, so there is no predictable result.)

Impact:
Cannot use direct Oracle monitoring to ensure the backend is functionally operational. OJDBC driver seems to negotiate the time zone for the session, and instead of 'UTC', it attempts to change the time zone to: 'Universal', 'Zulu', 'Etc/Universal', 'Etc/Zulu', which will cause the monitor to fail, and not execute the actual monitoring.

Note: Other time zones might be affected.For example, a similar issue might happen with the time zone set to GMT, which can become 'Greenwich' because of the same functionality.

Workaround:
Although there is no reliable workaround, reinstalling might resolve the issue, as may using another time zone.

Fix:
Oracle monitor functions now as expected with UTC and other time zones.

552498-2 : APMD basic authentication cookie domains are not processed correctly

Component: Access Policy Manager

Symptoms:
401 responses containing Set-Cookie headers might not be processed correctly. Domains that begin with a dot will be truncated and the cookies will not be sent to pool members.

Conditions:
An access policy needs to use Basic or NTLM authentication and one or more of the 401 responses must contain Set-Cookie headers. If a domain is specified and the domain begins with a dot, it will not be processed correctly.

Impact:
Cookies assigned during the authentication handshake might not be sent to pool members.

Workaround:
An iRule can be used to process the 401 responses and remove any leading dots from domain fields of Set-Cookie headers.

Fix:
Domain fields in Set-Cookie headers found in 401 responses are processed correctly.

552385 : Virtual servers using an SSL profile and two UDP profiles may not be accepted

Component: Local Traffic Manager

Symptoms:
Error message:
01070711:3: Found disallowed profile: Not Profile profile_clientssl
or
01070711:3: Found disallowed profile: Not Profile profile_serverssl

Conditions:
Create a virtual server with a client-ssl profile and/or a server-ssl profile and two different UDP profiles (one on the server side and one on the client side).

Impact:
When using either a client-ssl profile or a server-ssl profile, depending on the sort order of the UDP profiles, the configuration may not be accepted.

When using both a client-ssl profile and a server-ssl profile, the configuration is not accepted.

Workaround:
When using either a client-ssl profile or a server-ssl profile, either use a common UDP profile for both client and server side or try renaming one of the UDP profiles to alter the sort order.

When using both a client-ssl profile and a server-ssl profile, try using one UDP profile for both the client and server side.

Fix:
Virtual servers that utilize an SSL profile and a combination of UDP profiles are now accepted.

552352-3 : tmsh list display incorrectly for default values of gtm listener translate-address/translate-port

Solution Article: K18701002

Component: Global Traffic Manager (DNS)

Symptoms:
tmsh list displays incorrectly for default values of GTM listener translate-address/translate-port settings.

Conditions:
Using the tmsh list command to show translate-address/translate-port for GTM listener.

Impact:
tmsh list gtm listener does not display 'translate-address'/'translate-port' when it is set to enabled, but the command does show the values when it is set to disabled. The tmsh list gtm listener command should not show the default settings. This becomes an issue when used with the TMSH merge command, where the value gets set to the LTM virtual server default instead of maintained as the GTM Listener default. This might eventually result in failing traffic.

Workaround:
Use tmsh list with 'all-properties' instead.

Fix:
GTM Listener's translate-address and translate-port field are now always displayed in TMSH commands. This is because there are different defaults in GTM Listeners than the LTM virtual servers. When used with the TMSH merge command, the value gets set to the LTM virtual server default instead of maintained as the GTM Listener default. By always displaying this attribute, no matter what the value is, the merge will always be handled appropriately.

Solution Article: K27590443

Component: Wan Optimization Manager

Symptoms:
A memory leak occurs when APM application tunnels or AM iSession connections are aborted while waiting to be reused.

Conditions:
The iSession profile reuse-connection attribute is true.
A large number of iSession connections are aborted while waiting to be reused.

Impact:
Available memory might be significantly reduced when a large number of iSession connections waiting to be reused are aborted.

Workaround:
Disable the iSession profile reuse-connection attribute. Restart TMM.

Fix:
This release fixes an APM App Tunnel/AM iSession connection memory leak.

552151-1 : Continuous error report in /dev/log/ltm: Device error: n3-compress0 Nitrox 3, Hang Detected

Component: Local Traffic Manager

Symptoms:
Hardware compression slowly and progressively fails to handle compression operations. The system posts the following errors in ltm.log: crit tmm3[14130]: 01010025:2: Device error: n3-compress0 Nitrox 3.

Conditions:
This occurs when the system encounters errors during hardware compression handling. This occurs on the BIG-IP 5000-, 7000-, 10000-, and 12000-series platforms, and on VIPRION B22xx blades.

Impact:
Compression is (eventually) performed by software. This can result in high CPU utilization.

Workaround:
Disable compression if CPU usage is too high.

Fix:
Improved the device exception handling so that errors are correctly propagated to compression clients, thus preventing the progressive failure of the compression engine, and stopping the offload to software compression (which was driving up the CPU).

552139-3 : ASM limitation in the pattern matching matrix builtup

Solution Article: K61834804

Component: Application Security Manager

Symptoms:
The signature configuration is not building up upon adding new signatures. This can look like a configuration change is not finishing, or if it does, it may result in crashes when the Enforcer starts up resulting in constant startups.

Conditions:
Too many signatures are configured with custom signatures. The exact number varies (depending on the signature) but hundreds of signatures may be enough to trigger it.

Impact:
Configuration change doesn't finish or crashes in the ASM startup (which results in constant startups of the system).

Workaround:
Workarounds are possible only in a custom signature scenario, only using fewer signatures or by removing unused signatures.

Fix:
Fixed a limitation in the attack signature engine.

551927-3 : ePVA snoop header's transform vlan should be set properly under asymmetric routing condition

Component: TMOS

Symptoms:
On ePVA capable platform with fastl4 profile and asymetric routing on client side, ltm sends packets to the client with wrong vlan/correct mac address (or correct vlan and wrong mac-address) and undecremented ttl.

Conditions:
fastl4 profile and asymetric routing on client side

Impact:
Return traffic could use the wrong vlan

Workaround:
none

Fix:
Use the nexthop VLAN for ePVA transformation for offloaded flow when available, instead of the incoming VLAN

551767-2 : GTM server 'Virtual Server Score' not showing correctly in TMSH stats

Solution Article: K03432500

Component: Global Traffic Manager (DNS)

Symptoms:
GTM server 'Virtual Server Score' is not showing correct values in TMSH stats. Instead, stats shows zero value.

Conditions:
You have a virtual server configured with a non-zero score.

Impact:
tmsh show gtm server server-name detail lists 'Virtual Server Score' as zero. Note that there is no impact to actual load balancing decisions. Those decisions take into account the configured score. This is an issue only with showing the correct information and stats.

Workaround:
None.

Fix:
TMSH now shows the correct value for 'Virtual Server Score' when you have a virtual server configured with a non-zero score.

Solution Article: K14954742

Component: Access Policy Manager

Symptoms:
Successful execution of an Access Policy will result in the client receiving a HTTP status 500 error response when clientless mode is set. This error response is generated by APMD. This is a regression condition that occurs when the fix for bug 374067 is included.

Conditions:
-- The system has the fix for bug 374067.
-- Clientless mode is enabled.
-- BIG-IP platform is chassis platform.
-- The administrator does not override the Access Policy response with iRule command.

Impact:
Client receives an invalid response.

Workaround:
None.

Fix:
Upon successful execution of the Access Policy in clientless mode, the request is forwarded to the configured backend as needed.

551742-1 : Hardware parity error mitigation for the SOURCE_VP table on 10000s/10200v/10250v platforms and B4300/B4340N and B2250 blades

Component: TMOS

Symptoms:
In rare occurrences, BIG-IP hardware is susceptible to parity errors due to unknown source. This bug mitigates parity errors that occur in the SOURCE_VP table of the switch hardware, indicated with the following message in the ltm log:

Sep 15 12:12:12 info bcm56xxd[8066]: 012c0016:6: _soc_xgs3_mem_dma: SOURCE_VP.ipipe0 failed(NAK)

Conditions:
This occurs only on the BIG-IP 10000s/10200v/10250v platforms, and on the VIPRION B4300/B4340N and B2250 blades. The exact trigger of the parity error is unknown at this time.

Impact:
This impacts several series of BIG-IP products with hardware parity error mitigation capabilities.

Workaround:
Rebooting BIG-IP hardware should clear issues caused by hardware parity errors.

Fix:
A hardware parity error issue has been fixed.

---

551661-3 : Monitor with send/receive string containing double-quote may fail to load.

Component: TMOS

Symptoms:
When a monitor string contains contains \" (backslash double-quote) but does not contain a character that requires quoting, one level of escaping is lost at each save/load.

Note: Re-loading a config happens during licensing. If you decide to upgrade, first verify that you have an escaped quote in the monitor string. If you do, remove the re-licensing step from your MOP (Method of Procedure). The failure message for reloading the license with an escaped quote appears similar to the following example:

Monitor monitor_1 parameter contains unescaped " escape with backslash.

Conditions:
If the string contains \" (backslash double-quote) but does not contain one of the following characters: ' (single quote), | (pipe), { (open brace), } (close brace), ; (semicolon), # (hashtag), literal newline, or literal space.

Impact:
Monitors are marked down due to expected string not matching or incorrect send string. Potential load failure.

Workaround:
You can use either of the following workarounds:
-- Modify the content the BIG-IP system retrieves from the web server for the purposes of health monitoring, so that double quotes are not necessary.
-- Use an external monitor instead.

Fix:
If the monitor send-recv strings contain a double-quote ", character, the system now adds quotes to the input.

If a configuration contains '/"', does not reload the license before upgrade.

551481-4 : 'tmsh show net cmetrics' reports bandwidth = 0

Component: TMOS

Symptoms:
'tmsh show net cmetrics' reports bandwidth = 0

Conditions:
tcp profile enables cmetrics-cache.
connection involves at least 4 rtt updates.

Impact:
User cannot view cmetrics data.

Workaround:
For 12.0.0 and later, you can get this data using the ROUTE::bandwidth iRule. For earlier versions, there is no workaround.

Fix:
Properly compute bandwidth with the formula cwnd/rtt.

551349-1 : Non-explicit (*) IPv4 monitor destination address is converted to IPv6 on upgrade★

Solution Article: K80203854

Component: TMOS

Symptoms:
A monitor destination address in the form of *:port (IPv4) is converted to *.port when upgrading from 10.2.4 to 11.5.x.

Conditions:
A monitor exists with a non-explicit address and explicit port on a BIG-IP system running 10.2.4. Then upgrade to 11.5.x (or install 10.2.4 ucs)

Impact:
Monitors appears to function normally but they will have the wrong format in the config file.

Workaround:
None.

Fix:
Determine if non-explicit (*) address is ipv4 or ipv6 based on next character to be parsed.

551260-3 : When SAML IdP-Connector Single Sign On Service URL contains ampersand, redirect URL may be truncated

Component: Access Policy Manager

Symptoms:
When BIG-IP is used as SAML Service Provider, and IdP-Connectors Single Sign On Service URL contains ampersand (&),
part of the URL may be truncated when user is redirected to IdP for authentication.

Conditions:
All conditions must be true:
- BIG-IP is used as SAML Service Provider
- Single Sign On Service URL property of IdP connector contains ampersand, e.g. https://idp.f5.com/saml/idp/profile/redirectorpost/sso?a=b&foo=bar
- User performs SP initiated SSO

Impact:
The query part of the redirect URL after ampersand will be lost when user is redirected to SSO URL with Authentication Request.

Fix:
Redirect URL is no longer truncated after ampersand sign.

551208-3 : Nokia alarms are not deleted due to the outdated alert_nokia.conf.

Component: TMOS

Symptoms:
Some of the log messages watched by alertd changed between BIG-IP software versions 10.x to versions 11.x/12.x. However, the /etc/alertd/alert_nokia.conf file has not been updated accordingly.

Conditions:
Running versions 11.x/12.x and receiving targeted messages that match the 10.x regex key fields. This occurs when the Nokia snmp alarms are enabled. See K15435 at https://support.f5.com/csp/#/article/K15435

Impact:
Matching the specific fields in the log message fails, so the corresponding alarm is not deleted from the nokia_alarm table. This might cause SNMP alerts to not be broadcast in Nokia-specific environments.

Workaround:
None.

Fix:
The log messages watched by alertd and appearing in alert_nokia.conf now match each clear event key to its corresponding error definition, so alerts are recorded correctly.

551189-2 : Modifying an HTTP cookie value via the HTTP::cookie iRule API may yield to incorrect HTTP header data

Component: Local Traffic Manager

Symptoms:
Upon repeatedly modifying the same HTTP cookie value (in the Set-Cookie header) within an iRule attached to a virtual server, the HTTP::cookie API may produce stale HTTP header data (e.g. HTTP Set-Cookie header and/or other HTTP headers).

Conditions:
LTM Virtual Server handling HTTP traffic, with iRule attached which modifies a given HTTP cookie value through the HTTP::cookie API, on ingress and/or egress traffic (through the HTTP_REQUEST and/or HTTP_RESPONSE events). An example use-case for producing the error would be encrypting and decrypting HTTP cookies via an iRule.

Impact:
Repeatedly altering the same HTTP cookie value in an iRule, via the HTTP::cookie API, may yield to an HTTP request/response with inconsistent HTTP header data, including but not limited to the Set-Cookie HTTP header.

Workaround:
None.

Conditions:
If standard DNS requests are made against a Validating Resolver DNS cache that points to a second BIG-IP which in turn contains a wideip in a signed zone

Impact:
RRSIG present when not asked for, and RRSIG and AD drop from response upon expiration from the cache

Workaround:
N/A

Fix:
Update message encoding to depend on client DO bit.

550694 : LCD display stops updating and Status LED turns/blinks Amber

Solution Article: K60222549

Component: TMOS

Symptoms:
The LCD display may stop updating and the Status LED may turn Amber and begin blinking on BIG-IP 2000, 4000, 5000, 7000, or 10000-series appliances.

Conditions:
The Status LED turns Amber if the LED/LCD module stops receiving updates from the BIG-IP host, and begins blinking Amber if the LED/LCD module does not receive updates from the BIG-IP host for three minutes or longer.
This condition may occur if data transfers between the BIG-IP host and the LED/LCD module over the connecting USB bus becomes stalled.
Due to changes in BIG-IP v11.5.0 and later, the frequency and likelihood of this condition is greatly reduced, but may still occur under rare conditions.

Impact:
When this condition occurs, the front-panel LCD display does not display the current BIG-IP host status, and the Status LED blinks Amber. There is no impact to BIG-IP host operations, and no disruption to traffic.

Workaround:
This condition can be cleared by either of the following actions:
1. Press one of the buttons on the LCD display to navigate the LCD menus.
2. Issue the following command at the BIG-IP host console:
/sbin/lsusb -v -d 0451:3410.

Either action generates USB traffic, which triggers recovery from the USB stalled transfer condition.

Fix:
Auto-recovery from a USB stalled-transfer condition has been implemented, which prevents the Status LED from blinking Amber on BIG-IP 2000, 4000, 5000, 7000, 10000 or 12000-series appliances.

550689-3 : Resolver H.ROOT-SERVERS.NET Address Change

Component: Local Traffic Manager

Symptoms:
The IPv4 and IPv6 addresses for H.ROOT-SERVERS.NET are changing on December 1st 2015 from (128.63.2.53 / 2001:500:1::803f:235) to (198.97.190.53 / 2001:500:1::53). The old addresses will be good for 6 months after the change, and then the IPv4 address will go completely offline, and the IPv6 address is subject to go offline as well. More details http://h.root-servers.org/renumber.html

Conditions:
DNS Resolver uses hard-coded root hints for H.ROOT-SERVERS.NET.

Impact:
Incorrect address for a root-server means no response to that query.

Workaround:
There are 12 other root-servers that also provide answers to TLD queries, so this is cosmetic, but the addresses still need to be updated to respond to the change.

Fix:
Updated H.ROOT-SERVERS.NET to reflect the new IPv4 and IPv6 addresses taking effect December 1st, 2015 from (128.63.2.53 / 2001:500:1::803f:235) to (198.97.190.53 / 2001:500:1::53).

For more information, see H-Root will change its addresses on 1 December 2015, available here: http://h.root-servers.org/renumber.html.

Component: Service Provider

Symptoms:
Serverside connection stalls. Connection is not torn down and packets are not forwarded to serverside.

Conditions:
Selected pool member closes (via FIN) connection before sending CEA as part of Diameter handshake.

Impact:
Connection stalls until handshake timeout and then it is reset.

Workaround:
none

Fix:
Serverside diameter connections will be immediately reset if FIN is received before CEA (Capabilities-Exchange-Answer).

---

549971-3 : Some changes to virtual servers' profile lists may cause secondary blades to restart

Component: TMOS

Symptoms:
If a virtual server's ip-protocol is not set, then some changes to the list of attached profiles may cause a validation error on secondary blades. This will cause those blades to restart.

Conditions:
This may happen in some cases when changing the list of profiles attached to a virtual server, but does not happen if 'ip-protocol' was explicitly set by the user.

Impact:
mcpd will restart on secondary blades. This will cause most other daemons on those blades to restart as well, including the TMM. Traffic will be lost.

Workaround:
You should explicitly set the ip-protocol when changing the profiles of a virtual server. Then this bug will not occur.

Fix:
If a virtual server's ip-protocol was not set, then some changes to the list of attached profiles would cause a validation error on secondary blades. This would cause those blades to restart. This issue has been fixed.

549588-3 : EAM memory leak when cookiemap is destroyed without deleting Cookie object in it

Component: Access Policy Manager

Symptoms:
EAM memory growing and OOM kills EAM process under memory pressure.

Conditions:
This occurs when using access management such as Oracle Access Manager, when an authentication request is redirected to IDP (redirect URL is present) with cookies present, memory can grow unbounded.

Impact:
EAM memory usage increases and OOM kills EAM process if the system is under memory pressure.

Workaround:
No Workaround

Fix:
EAM memory usage no longer grows. Cookie objects are deleted prior to deleting cookieMap from obAction destructor.

---

549543-2 : DSR rejects return traffic for monitoring the server

Solution Article: K37436054

Component: TMOS

Symptoms:
System DB variable 'tm.monitorencap' controls whether the server monitor traffic is encapsulated inside DSR tunnel. If it is set to 'enable', monitor traffic is encapsulated, and return traffic is without the tunnel encapsulation. In such a case, the return traffic is not mapped to the original monitor flow, and gets rejected/lost.

Conditions:
System DB variable 'tm.monitorencap' is set to 'enable', and DSR server pool is monitored.

Impact:
Monitor traffic gets lost, and server pool is marked down.

Workaround:
None.

Fix:
The DSR tunnel flow now sets the correct underlying network interface, so that the return monitor flow can match the originating flow, which results in the DSR monitor working as expected.

---

549406-3 : Destination route-domain specified in the SOCKS profile

Solution Article: K63010180

Component: Local Traffic Manager

Symptoms:
The SOCKS profile route-domain setting is supposed to control which route domain is used for destination addresses. It is currently used to identify the listener/tunnel interface to use when forwarding the traffic, but does not set the route domain on the destination address used by the proxy to determine how to forward the traffic.

Conditions:
When the virtual server receives a SOCKS request and the route-domain is not the default (0).

Impact:
SOCKS connection fails immediately and the system returns the following message to the client: Results(V5): General SOCKS server failure (1). Traffic is forwarded correctly only when the destination is route-domain 0. Other route domains might result in error messages and possible failed traffic.

Workaround:
Use a destination route-domain of 0 when working with the SOCKS profile.

Fix:
The system now uses the destination route-domain specified in the SOCKS profile. This allows the SOCKS profile to work correctly when the destination is not in route-domain 0.

Conditions:
During the reconfiguration of more than one iApp by switching templates, prior and new templates to contain iRules with procedures of the same name.
After the second or later reconfiguration TMM may core.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Modify iApp template to generate procedures that have a unique name per iApp.

Fix:
TMM no longer cores when reconfiguring more than one iApp that contains iRule procedures of the same name.

548583-5 : TMM crashes on standby device with re-mirrored SIP monitor flows.

Component: Local Traffic Manager

Symptoms:
Occasionally, the standby system with a SIP monitor crashes in a configuration where the active system contains a forwarding virtual server with a wildcard IP address and port, with connection mirroring enabled.

Conditions:
This occurs on an active-standby setup in which there is an L4 forwarding virtual server or SNAT listener configuration with a wildcard IP address and port, and with connection mirroring enabled. Also, the standby has a SIP monitor configured.

Impact:
Packets that are sent by the SIP monitor on the standby get routed back to the active unit (possibly due to a routing loop) and are then sent to the standby because of the wildcard mirrored configuration. tmm on standby might crash. When the crash occurs, the standby system posts the following assert and crashes: tmm failed assertion, non-zero ha_unit required for mirrored flow.

Workaround:
-- If a routing or switching loop is the reason the packets come back to the active unit, then the routing issues can be eliminated.
-- The mirroring of the wildcard virtual server or SNAT listener can be disabled.

Fix:
TMM no longer crashes on standby device with re-mirrored SIP monitor flows.

548563-3 : Transparent Cache Messages Only Updated with DO-bit True

Component: Local Traffic Manager

Symptoms:
When a transparent cache stores a message with DNSSEC OK (DO) bit TRUE and its TTL expires, the message is only updated when a new message arrives with DO-bit TRUE.

Conditions:
Running a DNS transparent cache with clients requesting DNSSEC messages.

Impact:
When the DO-bit TRUE's cached message TTL expires, the general impact is DO-bit FALSE queries will be proxied until the message cache is updated with DO-bit TRUE.

Workaround:
None.

Fix:
The message cache is updated regardless of DO-bit state after TTL expiration. However, the cache prefers DO-bit TRUE messages, and will update the cached message if a newer one arrives with DNSSEC OK.

548385-1 : iControl calls that query key/cert from parent folder, and the name is missing the extension, result in incorrect results

Solution Article: K25231211

Component: TMOS

Symptoms:
If the active folder is not same as the folder in which the query is being run, and the corresponding key/cert extension is not present in the name of the key/certificate file, the query result returns incorrect results.

Conditions:
This occurs when iControl calls that query key/cert from parent folder, and the name is missing the extension.

Impact:
The query result returns incorrect results.

Workaround:
You can use one of the following workarounds:
-- Change the filename to include the extension.
-- Change to the folder containing the iControl call you are executing.

Fix:
The system now correctly loads key/cert/csr/crl files without an extension, so iControl calls that query those files from parent folder, now return correct results.

547942 : SNMP ipAdEntAddr indicates floating vlan IP rather than local IP

Component: TMOS

Symptoms:
An SNMP query response for ipAdEntAddr would sometimes return floating IPs rather than local IPs. This was due to the supporting software returning the first found IP address for a given vlan.

Conditions:
Problem started after upgrading to v11.5.1 Eng-HF7, from v10.2.4.
The same problem can happen on freshly installed 11.5.x as well.

Impact:
No impact to BIG-IP services, but the returned information to the SNMP query is sometimes incorrect.

Workaround:
None.

547815-2 : Potential DNS Transparent Cache Memory Leak

Solution Article: K57983796

Component: Local Traffic Manager

Symptoms:
When a transparent cache is populated with messages where the DNSSEC OK-bit is true, and a query with that bit true, arrives at or after the expiration of the message TTL, the system leaks all subsequent queries with DNSSEC OK set to false, up through the TTL of that message.

Conditions:
Running a DNS transparent cache with clients requesting DNSSEC messages.

Impact:
A few hundred bytes can leak on each clientside query, leading to a massive leak over a short period of time.

Workaround:
Disable DNSSEC on all cached messages by disabling DNSSEC on pool members.

Fix:
This release fixes a potential DNS transparent cache memory leak.

547732-3 : TMM may core on using SSL::disable on an already established serverside connection

Component: Local Traffic Manager

Symptoms:
TMM process may crash if the SSL::disable iRule command is used on a serverside with a connection that has already established SSL.

Conditions:
Use of the 'SSL::disable serverside' iRule command on a serverside connection that has already established SSL

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Do not use SSL::disable on an event where the serverside SSL connection is already established.

547532-6 : Monitor instances in a partition that uses a non-default route domain can fail validation on secondary blades

Component: TMOS

Symptoms:
Error messages similar to this are present in the ltm log:

-- err mcpd[9369]: 01020036:3: The requested monitor instance (/part10/test_mon 90.90.90.90%10 443 ltm-pool-member) was not found.
-- err mcpd[9369]: 01070734:3: Configuration error: Configuration from primary failed validation: 01020036:3: The requested monitor instance (/part10/test_mon 90.90.90.90%10 443 ltm-pool-member) was not found.

Conditions:
A chassis-based system with multiple blades. This can occur a few different ways:
- A monitor is attached to an object that is configured in a partition that uses a non-default route domain, but the address of the monitor is explicitly using the default route domain (e.g. %0).
- A monitor defined in the Common partition is attached to an object from a partition where the default route domain is different.

Impact:
Monitor instances in a partition that uses a non-default route domain can fail validation on secondary blades. mcpd restarts.

Workaround:
There are two possible workarounds:

-- Move the monitor to the /Common/ partition and do not specify %0 in the Alias Address.

-- Do not use monitors from other partitions where the default route domain is different.

Fix:
The complete state for addresses on the primary blade is propagated to secondary blades.

546747-4 : SSL connections may fail with a handshake failure when the ClientHello is sent in multiple packets

Solution Article: K72042050

Component: Local Traffic Manager

Symptoms:
Sometimes BIG-IP system responds with a fatal-handshake alert and closes the SSL session for a new connection when a ClientHello record is split between two or more packets.

If SSL debug logging is enabled, the system logs an error such as the following:
    01260009:7: Connection error: ssl_hs_rxhello:6210: ClientHello contains extra data (47).

Note: For information on SSL debug logging, see SOL15292: Troubleshooting SSL/TLS handshake failures at https://support.f5.com/kb/en-us/solutions/public/15000/200/sol15292.html.

Conditions:
This occurs when a SSL ClientHello record is split across multiple TCP segments, and the last segment is relatively small.

Impact:
SSL connections fail to complete with a handshake failure.

Workaround:
No workaround.

Fix:
SSL handshakes no longer fails to complete when the ClientHello is split across multiple TCP segments, and the last segment is relatively small.

546640-1 : tmsh show gtm persist <filter option> does not filter correctly

Component: Global Traffic Manager (DNS)

Symptoms:
Following commands fail to return results even if there are matching records:
  # tmsh show gtm persist level wideip
  # tmsh show gtm persist target-type pool-member

Conditions:
This only happens when running the tmsh commands listed in the Symptoms.

Solution Article: K02151433

Component: TMOS

Symptoms:
After upgrade from 10.x to 11.5.3 HF2, configuration fails to load with the following error:
01070734:3: Configuration error: Invalid primary key on monitor_param object () - not a full path 2.

Conditions:
Configuration contains a user-created monitor (A) that inherits from user-created monitor (B). Monitor A appears first within the configuration files and monitor B does not have a 'destination' attribute.

Impact:
Configuration fails to load.

Workaround:
Re-order monitors such that Monitor B appears first, or add a 'destination' attribute (i.e., 'destination *:*') to monitor B.

Fix:
10.x upgrade now completes successfully, even when parent monitors appear later in the monitor list, or when there is no destination attribute in the child monitor.

545821 : Idle timeout changes to five seconds when using PVA full or Assisted acceleration.

Component: Local Traffic Manager

Symptoms:
When FastL4 performs hardware acceleration during the TCP handshake, the FastL4 handshake timeout is not updated to match the profile timeout value after the connection is established.

Conditions:
Accelerated, established TCP flows with no traffic for more than five seconds.

Impact:
TCP flows in the established state are dropped if they have more than five seconds of inactivity.

Workaround:
Disable embedded Packet Velocity Acceleration (ePVA) acceleration.

Fix:
Once the TCP connection reaches established state, the idle timeout is set to the value found in the associated profile. By default the profile timeout value is 300 seconds.

545745-3 : Enabling tmm.verbose mode produces messages that can be mistaken for errors.

Component: TMOS

Symptoms:
When tmm first starts, the system logs multiple messages containing the words "error:" and "best_error:" in the tmm log files when tmm.verbose is enabled, and hardware accelerators are present.

Conditions:
Must have an accelerator device, and enable tmm.verbose logging.

Impact:
The system posts messages that could be mistaken for errors. For example: en: 1, clkf: 13, pll_MHz: 650, ddr_hertz: 650000000, error: 17000000, best_error: 667000000. These are not errors, and may be safely ignored.

Workaround:
Ignore the lines with format similar to the following:

 en: 1, clkf: 13, pll_MHz: 650, ddr_hertz: 650000000, error: 17000000, best_error: 667000000

Fix:
The cosmetic messages containing 'err' and 'best err' are no longer posted on initial tmm startup when tmm.verbose logging on hardware accelerated devices.

545704-3 : TMM might core when using HTTP::header in a serverside event

Component: Local Traffic Manager

Symptoms:
In certain circumstances TMM might core when using an HTTP iRule command in a HTTP_REQUEST_SEND serverside event.

Conditions:
- iRule with an HTTP command in a serverside event prior to the serverside being completely established, such as HTTP_REQUEST_SEND.
- OneConnect configured on the virtual server.

Impact:
The command might either return invalid value or lead to a condition where TMM might core.

Workaround:
Use the {clientside} Tcl command to execute on the client side.

Alternatively, you might use the HTTP_REQUEST_RELEASE event for HTTP inspection/modification on the server-side.

Fix:
TMM no longer cores when using HTTP iRule commands on the server-side of the HTTP_REQUEST_SEND event.

---

545450-2 : Log activation/deactivation of TM.TCPMemoryPressure

Component: Local Traffic Manager

Symptoms:
The TCP memory pressure feature allows packets to be randomly dropped when the TMM is running low on available memory. The issue is that these packets are dropped silently.

Conditions:
TM.TCPMemoryPressure set to "enable".

Impact:
Packets are dropped, where the cause of the drop cannot be easily determined.

Fix:
Logging added in /var/log/ltm for activation and deactivation of TCP memory pressure. The deactivation message also includes the number of packets and bytes dropped.

---

545263-2 : Add SSL maximum aggregate active handshakes per profile and per global

Component: Local Traffic Manager

Symptoms:
There is no limit to the number of active SSL handshakes on one BIG-IP system. With many calls, memory can be exhausted and cause system problems.

Conditions:
When the BIG-IP system has too many active SSL handshakes.

Impact:
The memory and/or CPU can be exhausted.

Workaround:
None.

Fix:
Added limitation for active SSL handshakes to prevent CPU and memory exhaustion. There is a new db variable 'tmm.ssl.maxactivehandshakes' that limits the total number of active SSL handshakes. By default this variable is set to '0', which means no limit.

Behavior Change:
There is a new db variable 'tmm.ssl.maxactivehandshakes', which limits the total number of active SSL handshakes. By default this variable is set to '0', which means no limit.

544992-2 : Virtual server profile changes are ignored if it has /Common/remotedesktop and /Common/vdi assigned (Citrix/Vmware View iApp)

Component: Access Policy Manager

Symptoms:
Changes to the profiles that are assigned to a virtual server are ignored if the /Common/remotedesktop and /Common/vdi profiles are already assigned to it. Some iApps that F5 provides to create Citrix or VMware View configurations assign those profiles to a virtual server.

Conditions:
/Common/remotedesktop and /Common/vdi profiles are assigned to a virtual server.

Impact:
Changes to the profiles assigned to a virtual server (adding a new new profile, deleting a profile, changing existing profiles) have no effect until either of these occurs: The /Common/vdi profile is removed from the virtual server or tmm is restarted.

Workaround:
Use tmsh to remove /Common/vdi from the profiles for the virtual server.
(There is no option in the GUI that allows you to do this.)

Fix:
The /Common/remotedesktop and /Common/vdi profiles can be assigned to a virtual server without affecting other profiles.

544980-1 : BIG-IP Virtual Edition may have minimal disk space for the /var software partition when deploying from the OVA file for the Better or Best license bundle.

Component: TMOS

Symptoms:
The size of /var volume is 500 MB instead of 3 GB for BETTER and BEST license bundles.

Conditions:
BIG-IP VE BETTER and BEST vm_bundle images.

Impact:
Not enough space in /var.

Workaround:
In the current volume:

1. Modify global_attributes file.
* The global_attributes file is located at /shared/.tmi_config, so modify global_attributes file by using vi command.

From:
{"TMI_VOLUME_FIX_VAR_MIB":"500","TMI_VOLUME_FIX_CONFIG_MIB":"500"}

To:
{"TMI_VOLUME_FIX_VAR_MIB":"3000","TMI_VOLUME_FIX_CONFIG_MIB":"500"}

2. Install version.

3. Modify global_attributes file to back original value.

4. Switchboot to newly installed volume.

5. To change /var to 3 GB and from tmsh, run the following command:
modify /sys disk directory /var new-size 3145728

6. Reboot.

Fix:
BIG-IP Virtual Edition now has 3GB of disk space for the /var software partition when deploying from OVA for the Better or Best license bundle

544913-2 : tmm core while logging from TMM during failover

Solution Article: K17322

Component: TMOS

Symptoms:
TMM crash and coredump while logging to remote logging server when an HA failover occurs.

Conditions:
The problem might occur when:
1. A log message is created as the result of errors that can occur during log-connection establishment.
2. An error occurs while attempting to connect to the remote logging server.
3. The Primary HA member fails over. The crash occurs on the HA member which was the Primary member prior to the failover.

Impact:
TMM runs out of stack and dumps core. Stack trace shows recursion in errdefs. The system cannot function under these conditions. This is an issue that might occur anytime logs are generated when managing resources that are also used by the logging system itself.

Workaround:
Two possible workarounds are available:
1) Create a log filter specifically for message-id :1010235: that either discards or directs such messages to local syslogs.
2) If the problem occurs on TMM startup, disable and then re-enable the corresponding log source once the TMM starts up.

Fix:
Logging recursion no longer occurs in TMM during failover while the system is attempting to connect to the remote logging server.

544831 : ASM REST: PATCH to custom signature set's attackTypeReference are ignored

Component: Application Security Manager

Symptoms:
When trying to update filter/attackTypeReference for a User-Defined Filter-Based Signature Set (/mgmt/tm/asm/signature-set/<ID>), the PATCH call completes successfully, but the change never occurred.

Conditions:
Using the REST API, a user tries to update filter/attackTypeReference for a User-Defined Filter-Based Signature Set (/mgmt/tm/asm/signature-set/<ID>)

Impact:
The PATCH call completes successfully, but the change never occurred. This may result in the Signature Set not containing the expected signatures.

Workaround:
The bug only exists via the REST API, the GUI can be used to change this value.

Fix:
The attackTypeReference field is now correctly updated using a REST PATCH.

---

544481-4 : IPSEC Tunnel fails for more than one minute randomly.

Component: TMOS

Symptoms:
IPsec IKEv1: DPD ACK may be dropped when excessive DPD message exchange. This causes the IPsec tunnel to fail.

Conditions:
Excessive DPD message exchange.

Impact:
Connection resets.

Workaround:
None.

Fix:
Excessive DPD message exchange no longer causes the IPsec tunnel to fail.

---

544375-2 : Unable to load certificate/key pair

Component: Local Traffic Manager

Symptoms:
After creating SSL profile, 'could not load key/certificate file' appears in /var/log/ltm with profile name. Unable to connect to virtual with SSL profile.

Conditions:
Certificate uses sha1WithRSA or dsaWithSHA1_2 signature algorithm.

Impact:
Unable to load certificate.

Workaround:
None.

Fix:
Can now load certificates with sha1WithRSA or dsaWithSHA1_2 signature algorithm.

544325-2 : BIG-IP UDP virtual server may not send ICMP Destination Unreachable message Code 3 (port unreachable).

Solution Article: K83161025

Component: Local Traffic Manager

Symptoms:
A BIG-IP UDP virtual server may not send an ICMP Destination Unreachable message Code 3 (port unreachable). As a result of this issue, you may encounter the following symptoms:

-- Client applications may not respond or appear to hang.
-- When attempting to troubleshoot the connectivity issue from remote devices, no ICMP diagnostic data is available from the BIG-IP system.

Conditions:
This issue occurs when the following condition is met: All pool members for the UDP virtual server are unavailable.

Impact:
In versions 11.3.0 through 11.4.1, the system silently drops the request. In versions 11.5.0 and later, the system sends back the ICMP message with type 13 ('administratively filtered').

Workaround:
None.

Fix:
LTM now sends back an ICMP Destination Unreachable message Code 3 (port unreachable), which is expected behavior.

Behavior Change:
In version 11.2.1 and earlier, the system responded to a request with an ICMP packet containing the type code 'port unreach' when a UDP virtual server pool member was down due to no available pool members. For the same scenario in versions 11.3.0 through 11.4.1, the system sends no ICMP packet. In versions 11.5.0 through this hotfix/release, the system sends an ICMP pa
