707675 : FQDN nodes or pool members flap when DNS response received

Component: Local Traffic Manager

Symptoms:
When an LTM pool is configured with FQDN nodes or pool members, the LTM pool and associated virtual server(s) may transition from an UP to DOWN state and back over a period of a few seconds.

Such an event is accompanied by log messages similar to the following:

-- notice mcpd[#]: 01071682:5: SNMP_TRAP: Virtual /Common/vs_test has become unavailable
-- notice mcpd[#]: 010719e7:5: Virtual Address /Common/123.45.67.89 general status changed from GREEN to RED.
-- notice mcpd[#]: 010719e8:5: Virtual Address /Common/123.45.67.89 monitor status changed from UP to DOWN.
-- err mcpd[#]: 01020066:3: The requested Pool Member (/Common/Test_Pool /Common/test-dummy.com-12.34.56.78 443) already exists in partition Common.
-- notice bigd[##]: 01060144:5: Pool /Common/Test_Pool member /Common/test-dummy.com-12.34.56.78 session status enabled by monitor
-- notice bigd[##]: 01060145:5: Pool /Common/Test_Pool member /Common/test-dummy.com-12.34.56.78 monitor status up. [ /Common/mon_test_https: UP ] [ was checking for 0hr:0min:2sec ]
-- notice mcpd[#]: 01071681:5: SNMP_TRAP: Virtual /Common/vs_test has become available
-- notice mcpd[#]: 010719e7:5: Virtual Address /Common/123.45.67.89 general status changed from RED to GREEN.
-- notice mcpd[#]: 010719e8:5: Virtual Address /Common/123.45.67.89 monitor status changed from DOWN to UP.

This symptom repeats each time a DNS query is performed to resolve the FQDN node/pool-member name to its IP addresses, based on the 'interval' value configured for the FQDN node.

This symptom occurs only when the 'autopopulate' value is set to 'enabled' for the FQDN node/pool-member.

Conditions:
-- LTM pool is configured with FQDN nodes or pool members.
-- The 'autopopulate' value is set to 'enabled' for the FQDN node/pool-member.

Impact:
LTM pool and virtual server are briefly and periodically marked DOWN. Traffic may be impacted.

Workaround:
Either of the following methods can be used to work around this issue:

-- Configure static IP addresses instead of FQDN nodes/pool-members.

-- Set the 'autopopulate' value to 'disabled' for the FQDN node/pool-member, if possible (that is, if only one IP address is required/expected to be returned for the FQDN name, which means that the 'autopopulate' feature of FQDN nodes/pool-members is not required).

Fix:
FQDN node/pool-member and corresponding pool and virtual server are no longer briefly marked DOWN when the DNS server is queried to resolve the FQDN name, with the 'autopopulate' feature enabled for the FQDN node/pool-member. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

707226-2 : DB variables to disable CVE-2017-5754 Meltdown/PTI mitigations

Component: TMOS

Symptoms:
Mitigations might CVE-2017-5754 Meltdown/PTI (Page Table Isolation) can negatively impact performance.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

Conditions:
Mitigations for CVE-2017-5754 Meltdown/PTI (Page Table Isolation) enabled.

Impact:
Meltdown/PTI mitigations may negatively impact performance.

Workaround:
Disable CVE-2017-5754 Meltdown/PTI mitigations.

To turn off mitigations for CVE-2017-5754 Meltdown/PTI, run the following command:

tmsh modify sys db kernel.pti value disable

Note: Turning off these mitigations renders the system vulnerable to CVE-2017-5754 Meltdown; but in order to take advantage of this vulnerability, they must already possess the ability to run arbitrary code on the system. Good access controls and keeping your system up-to-date with regards to security fixes will mitigate this risk on non-VCMP systems. vCMP systems with multiple tenants should leave these mitigations enabled.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

Fix:
On releases that provide mitigations for CVE-2017-5754 Meltdown/PTI, the protection is enabled by default, but can be controlled using db variables.

Please see https://support.f5.com/csp/article/K91229003 for additional Spectre and Meltdown information.

706631 : A remote TLS server certificate with a bad Subject Alternative Name should be rejected when Common Criteria mode is licensed and configured.

Component: Local Traffic Manager

Symptoms:
According to RFC2818, if the certificate sent by the TLS server has a valid Common Name, but the Subject Alternative Name does not match the Authenticate Name in the server-ssl profile, the connection should be terminated.

Conditions:
-- A server-ssl profile is enabled on a virtual server and has the 'authenticate-name' property set.

-- The TLS server presents a certificate in which the Subject Alternative Name does not match the configured authenticate-name.

-- Common Criteria mode licensed and configured.

Impact:
A TLS connection succeeds which should fail.

Workaround:
There is no workaround at this time.

Fix:
A remote TLS server certificate with a bad Subject Alternative Name is now rejected when Common Criteria mode is licensed and configured.

---

706305-2 : bgpd may crash with overlapping aggregate addresses and extended-asn-cap enabled

Component: TMOS

Symptoms:
bgpd may crash on a BIG-IP system configured for dynamic routing announcing multiple overlapping aggregate-addresses with extended asn capabilities enabled.

Conditions:
- BGP enabled on route-domain
- BGP configured to announce several overlapping aggregate-addresses
- BGP configured with extended-asn-cap enabled.

Impact:
Inability for the unit to use BGP

Workaround:
Disabling extended-asn-cap or not announcing multiple overlapping aggregate addresses may allow to workaround this issue.

Fix:
bgpd no longer crashes with overlapping aggregate addresses and extended-asn-cap enabled

---

706086-1 : PAM RADIUS authentication subsystem hardening

---

705794-1 : Under certain circumstances a stale http2 stream can cause a tmm crash

Component: Local Traffic Manager

Symptoms:
A HTTP2 stream is getting overlooked when cleaning up a HTTP2 flow.

Conditions:
Currently only known is that the closing_stream is not empty. Exact entrance conditions not clear.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

Fix:
HTTP2 flows are properly cleaned up to prevent a tmm crash.

---

705611-1 : The TMM may crash when under load when configuration changes occur when the HTTP/2 profile is used

Component: Local Traffic Manager

Symptoms:
The TMM may later crash after a configuration change done under load if the HTTP/2 profile is used.

Conditions:
A configuration change occurs. The configuration change is large enough, or the TMM load large enough that the change is not synchronous. The change involves a HTTP/2 profile.

Data traffic progresses through a partially initialized HTTP/2 virtual server, potentially causing a later crash.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
There is no workaround at this time.

Fix:
Large configuration changes to the TMM involving a HTTP/2 profile will no longer potentially cause a TMM crash.

---

704804-2 : The NAS-IP-Address in RADIUS remote authentication is unexpectedly set to the loopback address

Component: TMOS

Symptoms:
The NAS-IP-Address in RADIUS remote authentication requests is set to the loopback address, not the management IP.

Conditions:
This applies to remote authentication for the control plane, not APM.

Impact:
Login may be impacted.

Workaround:
There is no workaround at this time.

---

704733-2 : NAS-IP-Address will be sent with the bytes backwards

Component: TMOS

Symptoms:
The NAS-IP-Address will have the address of the local device sent with the bytes backwards (78.56.30.172 where 172.30.56.78 would be expected).

Conditions:
This affects IPv4 addresses only.

Impact:
The server may be configured to check the NAS-IP-Address before allowing logins, in which case it would fail.

Workaround:
There is no workaround at this time.

Fix:
This has been corrected.

---

704666-2 : memory corruption can occur when using certain certificates

Component: Local Traffic Manager

Symptoms:
If a certificate has an extremely long common name, or an extremely long alternative name and is attached to an SSL profile, memory corruption can occur when loading the profile.

Conditions:
An SSL profile is loaded with a certificate containing an extremely long common name or subject alternative name.

Impact:
TMM could crash.

Workaround:
Do not use certificates with extremely long common names

Fix:
A length check has been added to avoid corruption when using extremely long common names.

---

704580-3 : apmd service may restart when BIG-IP is used as SAML SP while processing response from SAML IdP

Component: Access Policy Manager

Symptoms:
Under certain conditions apmd service may restart when processing response from SAML IdP.

Conditions:
BIG-IP is configured as SAML SP. BIG-IP is processing SAML message from IdP

Impact:
Temporarily users will not be able to authenticate agains BIG-IP
until apmd service starts up.

Workaround:
There is no workaround at this time.

Fix:
apmd service will no longer restart when processing messages from IdP.

704073-3 : Repeated "bad transition" OOPS logging may appear in /var/log/ltm and /var/log/tmm

Component: Local Traffic Manager

Symptoms:
"bad transition" OOPS messages may be repeatedly logged to /var/log/ltm and /var/log/tmm over time, polluting the log files.

Conditions:
No definitive user-discernable conditions. Use of SSL functionality may cause this form of logging.

Impact:
Log pollution and potential for performance degradation.

Workaround:
The logging can be suppressed via 'tmsh modify sys db tmm.oops value silent'

Fix:
The "bad transition" OOPS logging has been demoted to debug builds only.

---

---

703869-1 : Waagent updated to 2.2.21

Component: TMOS

Symptoms:
Microsoft updates waagent via an opensource process, but it is not compatible with BIG-IP software, and so cannot be upgraded outside of BIG-IP releases. Without this, Microsoft will not support older releases of BIG-IP systems in their environment.

Conditions:
Using Microsoft Azure.

Impact:
Microsoft does not support the version of waagent shipped as part of BIG-IP software.

Workaround:
None.

Fix:
Waagent was updated to 2.2.21 from Microsoft along with F5 changes for compatibility with BIG-IP software.

---

703761-1 : Disable DSA keys for public-key and host-based authentication in Common Criteria mode

Component: TMOS

Symptoms:
On a BIG-IP system configured for Common Criteria (CC) mode, DSA keys can still be used for key-based authentication to the BIG-IP system.

Conditions:
-- Running a CC release with CC Mode enabled.
-- Attempt to SSH-connect to the BIG-IP system from another system with a DSA key.
-- That DSA key is present in the BIG-IP system's authorized_keys file.

Impact:
If the key is in the BIG-IP system's authorized_keys file, public-key authentication succeeds, when DSA authentication should be disabled in CC mode.

Workaround:
There is no workaround at this time.

Fix:
DSA SSH keys are now disabled for public-key and host-based authentication in Common Criteria mode, as expected.

---

703429-1 : Citrix Receiver for Android (v3.13.1) crashes while accessing PNAgent services

Component: Access Policy Manager

Symptoms:

---

702946-2 : Added option to reset staging period for signatures

Component: Application Security Manager

Symptoms:
In cases where a staging period was started, but no traffic passed through security policy, you might want to reset the staging period when traffic starts, but there is no option to do so.

Conditions:
Staging enabled for signatures in policy.

Impact:
There is a suggestion to enforce the signature before any traffic can influence this decision.

Workaround:
If all signatures are staged, you can enforce them all, and then enable staging again.

Note: Apply policy is required between actions.

Fix:
Added option to reset the staging period for all or specific signatures. In modal windows shown after clicking 'Change properties...' on the Policy Signatures screen, when 'No' is not selected for 'Perform Staging', the system presents a checkbox: Reset Staging Period.

702738 : Tmm might crash activating new blob when changing firewall rules

Solution Article: K32181540

Component: Advanced Firewall Manager

Symptoms:
TMM crashes with core when changing firewall rules. TMM can enter a crash-loop, so it will crash again after restarting.

Conditions:
Updating, removing or adding firewall rules.

Specific characteristics of change that can cause this issue are unknown; this issue occurs rarely.

Impact:
Data traffic processing stops.

Workaround:
There are two workaround options:
Option A
1. Delete all policies.
2. Create them again without allowing blob compilation.
3. Repeat steps 1 and 2 until all the policies have been created (enable on-demand-compilation).

Option B
Modify all the rules simultaneously.

For example, the following steps will resolve this issue:
1. Enable on-demand-compilation
2. Select an IP address that is not used in any rules, e.g., 1.1.1.1.
3. Add that IP address to all the rules/source in all of the policies. To do so, run the following command for each policy:
tmsh modify security firewall policy POLICY_NAME rules modify { all { source { addresses add { 1.1.1.1 } } } }

4. Delete the IP address (restore rules) in all of the policies. To do so, run the following command for each policy:
tmsh modify security firewall policy POLICY_NAME rules modify { all { source { addresses delete { 1.1.1.1 } } } }
5. Disable on-demand-compilation. Doing so starts new blob compilation.

Fix:
TMM no longer crashes when changing firewall rules.

701626-1 : GUI resets custom Certificate Key Chain in child client SSL profile

Component: TMOS

Symptoms:
In the GUI, editing a client SSL profile or selecting a different parent profile changes the Certificate Key Chain to default (i.e., /Common/default.crt and /Common/default.key).

Conditions:
This happens in the following scenario:

1. Using the GUI, create a client SSL profile.
2. Configure the new profile to inherit from a client SSL profile other than the default, clientssl.
3. Click the Custom box for Certificate Key Chain and select a different cert and key from the default.
4. Click Update.
5. In the GUI, change any setting in the newly created profile, or select a different parent profile (but not the clientssl profile).
6. Click Update again.

Impact:
The system resets Certificate Key Chain to default, even though the Custom box is checked.

Workaround:
To work around this issue in the GUI, click the Custom checkbox next to the 'Certificate Key Chain' option in the parent profile. This will set the value of inherit-certkeychain to false , preventing the issue from occurring.

You can also use tmsh to update parent profile settings to avoid the occurrence of this issue..

Fix:
GUI no longer resets custom Certificate Key Chain in child client SSL profiles.

701609 : Static member of pool with FQDN members may revert to user-disabled after being re-enabled

Component: Local Traffic Manager

Symptoms:
Within an LTM pool containing both FQDN members and members configured with static IP addresses; a statically-configured member that had been disabled (session = user-disabled) and then re-enabled (session = user-enabled) may become disabled again after making other changes affecting the state of other FQDN members of the pool.

Conditions:
This may occur under the following conditions:
- An LTM pool containing a mix of FQDN and statically-configured members.
- A statically-configured pool member is disabled (session = user-disabled) and then re-enabled (session = user-enabled).
- Other changes occur which affect the availability of FQDN pool members.
For example, if a route to an FQDN pool member is deleted and recreated, a previously-disabled statically-configured member may revert to a disabled state.

Depending on circumstances, the issue may only occur once after BIG-IP, TMM, bigd, or a related daemon restarts.

Impact:
A pool member may be unexpectedly disabled after being re-enabled, and thus would not receive traffic.

Workaround:
It may be possible to work around this issue by disabling and re-enabling the statically-configured pool member again.

Fix:
Statically-configured pool members of a pool that also contains FQDN members remain enabled after being manually disabled then re-enabled. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

701249-2 : RADIUS authentication requests erroneously specify NAS-IP-Address of 127.0.0.1

Component: TMOS

Symptoms:
RADIUS requests from BIG-IP have attribute NAS-IP-Address = 127.0.0.1, which might cause authentication to fail.

The NAS-IP-Address is essentially the resource an end user client is trying to authenticate to. This is typically the management IP address of the BIG-IP system, but the BIG-IP system always sends 127.0.0.1 instead. That might fail or it might work, depending on how the server is configured.

Conditions:
This is an issue for all RADIUS authentication requests that use the attribute NAS-IP-Address.

Note: This affects remote control plane authentication only, not APM or other uses of RADIUS.

Impact:
BIG-IP system always sends 127.0.0.1 instead of the BIG-IP system's management IP address. RADIUS server might not service the request, so authentication fails.

Workaround:
There is no workaround.

---

700783-3 : Machine certificate check does not check against all FQDN hostnames

Component: Access Policy Manager

Symptoms:
macOS machine can be on multiple networks simultaneously, so it might have multiple hostnames. Machine certificate check does not check against all FQDN hostnames. This causes failure in certain scenarios.

Conditions:
-- macOS configuration with multiple hostnames.
-- The 'match FQDN with subject alt name' option is specified for machine certificate check.

Impact:
Machine cert check might fail.

Workaround:
No workaround at this time.

Fix:
Previously, with a macOS system that had multiple hostnames, the machine certificate check could not check against all hostnames, causing failures in some scenarios. Now, the machine certificate check compares all hostnames on macOS devices.

---

700780-4 : F5 DNS Relay Proxy service now warns about and clears truncated flag in proxied DNS responses

Component: Access Policy Manager

Symptoms:
F5 DNS Relay Proxy service does not support DNS-over-TCP requests, so if, in some configuration, the client resolver decides to use TCP for DNS resolution, this packet is not re-routed/proxied by the DNS Relay Proxy service, and may be causing DNS to be resolved using an incorrect DNS server (where the system decides to send it).

Typically, if a client receives DNS response with the TC flag set, it retries using TCP. Clearing the TC flag makes client resolver not use TCP at all, preventing DNS packets leakage.

Conditions:
-- DNS server responds with TC flag set in DNS response packet.
-- Windows only is affected.

Impact:
DNS resolution may not work as designed, as the system might send a packet to an incorrect DNS server.

Workaround:
None.

Fix:
Now F5 DNS Relay Proxy service clears TC flag in all proxied packets, preventing client DNS resolvers from using TCP. An appropriate log entry is printed into the service's log.

700564-2 : JavaScript errors shown when debugging a mobile device with ASM deviceID enabled

Component: Application Security Manager

Symptoms:
When debugging a mobile device with ASM Device ID enabled, the Google Chrome browser console log contains JavaScript errors similar to the following: net::ERR_UNKNOWN_URL_SCHEME.

Note: In order to view the Chrome browser console log, you must use BrowserStack from a developer's console, or physically connect the phone by cable, enable 'usb debug',
enable 'device discovery' on Chrome on the desktop, and view the console from there.

Conditions:
-- ASM policy is attached on a virtual server with deviceID enabled.
-- Device ID collection request has been sent from a mobile device.
-- Chrome browser console log is opened.

Impact:
Mobile device app developers might be concerned about the errors, potentially asking about why the ASM JavaScript code attempts to access UNKNOWN_URL_SCHEME in a mobile device.

The errors occur because Device ID enabled on an ASM policy uses the JavaScript request URI argument 'chrome-extension' to detect the existence of malicious browser extension. However, Chrome on Android/iOS does not support 'chrome-extension'.

Workaround:
Disable Device ID in ASM policy.

Fix:
The system now avoids checking Chrome extensions on mobile devices, so no UNKNOWN_URL_SCHEME errors occur.

695117 : bigd cores and sends corrupted MCP messages with many FQDN nodes

Solution Article: K30081842

Component: Local Traffic Manager

Symptoms:
When configured to monitor large numbers of nodes and/or pool members including FQDN nodes and/or pool members, the following symptoms may occur:
- bigd may core (aborted by sod due to missed heartbeat).
- bigd may produce corrupted MCP messages.
- FQDN nodes and/or pool members may remain in a Checking state indefinitely.

Conditions:
These symptoms may occur on affected versions of BIG-IP when a large number of nodes and/or pool members including FQDN nodes and/or pool members are configured. Depending on the capabilities of the platform in use, approximately one thousand (1,000) or more total nodes and/or pool members may be required to produce these symptoms.

FQDN nodes and/or pool members generate a more significant workload for the bigd daemon than nodes and/or pool members with statically-configured IP addresses. This additional load contributes to high CPU usage and the other observed symptoms.

Impact:
This issue produces the following impacts:
- bigd may core.
- nodes and/or pool members may remain in a Checking state indefinitely.
- bigd may produce corrupted MCP messages, which generate error messages in the LTM log of the following form:

... err mcpd[####]: 01070712:3: Caught configuration exception (0), Can't parse MCP message, ...

Examination of the corrupted MCP message shows objects at the point of corruption that have no hierarchical relationship with the objects referenced at the beginning of the message.

Workaround:
To work around this issue, use the following approaches singly or in combination:
1. Reduce the number of nodes and/or pool members configured for a given BIG-IP system.
2. Configure nodes and/or pool members with statically-configured IP addresses.

Fix:
bigd no longer produces corrupted MCP messages, resulting in nodes and/or pool members remaining in a 'checking' state, with up to 2,000 nodes and/or pool members including FQDN nodes and/or pool members configured. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

692095-3 : bigd logs monitor status unknown for FQDN Node/Pool Member

Solution Article: K65311501

Component: Local Traffic Manager

Symptoms:
While monitoring FQDN nodes or pool members, bigd may log the current or previous monitor status of the node or pool member as 'unknown' in messages where that state internally could have been logged as 'checking' or 'no address' for FQDN template nodes. Other states for FQDN configured nodes or pool members log monitor status as expected. Messages are similar to the following:

notice bigd[####]: 01060141:5: Node /Common/node_name monitor status unknown [ ip.address: unknown ] [ was up for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: unknown ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060141:5: Node /Common/node_name monitor status up [ ip.address: up ] [ was unknown for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status unknown. [ ] [ was unchecked for ##hrs:##mins:##sec ]
notice bigd[####]: 01060145:5: Pool /Common/pool_name member /Common/node_name monitor status up. [ ] [ was unknown for ##hrs:##mins:##sec ]

Conditions:
This may occur of the FQDN template node or pool member is in a 'checking' or 'no address' state.
The 'checking' state may occur if the DNS resolution of the FQDN node or pool member name is in progress.
The 'no address' state may occur if no IP addresses were returned by the DNS server for the configured FQDN node or pool member name.

Impact:
Unable to triage state of FQDN nodes or pool members identified in these log messages, to determine whether further troubleshooting is required, or what specific problem condition might require further investigation.

Workaround:
None.

Fix:
An FQDN-configured node or pool member logs each internal monitor status, including for scenarios of 'checking' and 'no address' for FQDN template nodes which were previously logged as 'unknown'.

691670-3 : Rare BD crash in a specific scenario

Solution Article: K02515009

Component: Application Security Manager

Symptoms:
BD crash or False reporting of signature ID 200023003.

Conditions:
JSON/XML/parameters traffic (should not happen with the enforce value signature).

Impact:
Failover, traffic disturbance in the core case. False positive violation or blocking in the other scenario.

Workaround:
Removing attack signature 200023003 from the security policy stops the issue.

Fix:
Fix a bug in the signatures engine that causes a false positive reporting of a signature. In some rare cases, this false reporting may cause a crash.

A newly released attack signature update changes the signature in a way that it no longer causes the issue to happen.

691017-1 : Preventing ng_export hangs

Component: Access Policy Manager

Symptoms:
Sometimes ng_export is stuck while reading tmsh thru the pipe because of buffer issues. Export is trying to read more data from tmsh while data is lost in the middle of the read operation.

Conditions:
-- ng_export receives tmsh replies through buffer of constant size x.
-- During the read operation, tmsh returns a buffer size of x minus k, where k is very small random number (less than 50).

Note: K is very small random number, which makes this issue difficult to describe.

Impact:
The export operation hangs.

Workaround:
None.

Fix:

689826-2 : Proxy/PAC file generated during VPN tunnel is not updated for Windows 10 (unicode languages like: Japanese/Korean/Chinese)

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.

689577-1 : ospf6d may crash when processing specific LSAs

Solution Article: K45800333

Component: TMOS

Symptoms:
When OSPFv3 is configured and another router in the network performs a graceful restart, ospf6d may crash.

Conditions:
-- OSPFv3 in use.
-- Graceful restart initiated by another system.

Impact:
OSPFv3 routing will interrupted while the daemon restarts and the protocol re-converges.

Workaround:
Disabling graceful restart on other network systems will prevent ospf6d from crashing on the BIG-IP system. However, it will cause a routing interruption on a system that restarts.

Fix:
The ospf6d daemon no longer crashes when a graceful restart occurs in the network.

---

689449-3 : Some flows may remain indefinitely in memory with spdy/http2 and http fallback-host configured

Component: Local Traffic Manager

Symptoms:
As a result of a known issue, in some circumstances the system may experience an unconstrained TMM memory growth when a virtual server is configured for spdy/http2 and http with fallback-host.

Conditions:
- VIP configured with spdy/http2 and http with fallback-host.

Impact:
TMM may eventually enter aggressive sweeper mode where this memory will be released. In the process it is possible that some legitimate connections will killed.

Workaround:
No workaround at this time.

Fix:
BIG-IP no longer attempts to send a response with a configured fallback host in HTTP profile, when a connection is aborted by a client or due to an internal error. It prevents the internal flow to stay in memory after the connection has died.

---

689089-3 : VIPRION cluster IP reverted to 'default' (192.168.1.246) following unexpected reboot

Component: Local Traffic Manager

Symptoms:
The cluster configuration file can be lost or corrupted, resulting in the out-of-band cluster management IP reverting to the default value.

Conditions:
Unexpected system restart while the configuration file is being updated may cause the file to become corrupted. If this occurs, the following error will be logged during blade startup:

"err clusterd[8171]: 013a0027:3: Chassis has N slots, config file has 0, ignoring config file"

Where "N" is the number of physical slots in the chassis (2, 4, or 8).

Impact:
Management IP reverts to 192.168.1.246, resulting in loss of access to the chassis through the out-of-band management network.

Workaround:
If this occurs, the management IP can be restored using TMSH or the UI through an in-band self IP, or with TMSH through the management console port.

Fix:
The configuration file update logic has been changed to prevent file corruption during update.

687658-2 : Monitor operations in transaction will cause it to stay unchecked

Solution Article: K03469520

Component: TMOS

Symptoms:
If a monitored object is deleted and created or modified in the same transaction, and any of its monitor configuration is changed (either the monitor, or the state user-down), the monitor state will become unchecked.

Conditions:
This only happens within transactions.

Note: Using the command 'modify ltm pool <name> members replace-all-with' is considered a transaction containing a delete and create of pool members.

Impact:
Monitor state never returns to its correct value.

Workaround:

---

687098 : IPv6 RADIUS servers not supported for remote authentication

Component: TMOS

Symptoms:
Authenticating against an IPv6 RADIUS server is not supported, only an IPv4 server.

Conditions:
This applies to remote authentication to log on to the BIG-IP system for management purposes.

Impact:
Logon operation will time out, as if the server did not respond.

Workaround:
Use an IPv4 server. If you have an IPv6 management IP, then you will need to have the IPv4 server reachable over a dataplane VLAN.

Fix:
Support for IPv6 RADIUS servers has been added.

---

686972-1 : The change of APM log settings will reset the SSL session cache.

Component: Local Traffic Manager

Symptoms:
If you change the configuration of APM log settings, it might cause the SSL session cache to be reset. Also, subsequent resumption of SSL sessions may fail after such change causing a situation where full ssl handshakes may occur more frequently.

Conditions:
-- Change the configuration of APM log settings.
-- SSL session cache is not empty.

Impact:
The change of APM log settings resets the SSL session cache, which causes the SSL session to initiate full-handshake instead of abbreviated re-negotiation.

Workaround:
Follow this procedure:
1. Change access policy.
2. The status of that access policy changes to 'Apply Access Policy'.
3. Re-apply that.

Fix:
The change of APM log settings now limits its effect on APM module instead of affecting other (SSL) module's data.

686389-3 : APM does not honor per-farm HTML5 client disabling at the View Connection Server

Component: Access Policy Manager

Symptoms:
Current logic for determining whether to offer HTML5 client option works for Horizon 6.x (and earlier) but it does not work for Horizon 7.x.

With Horizon 7.x, VMware has enhanced the XML so that each resource includes a flag to indicate whether HTML5 client is enabled (absence of <html-access-disabled/> tag). APM does not honor this flag to show HTML5 client option to APM end user only if it has been enabled for that resource.

Conditions:
-- APM webtop with a VMware View resource assigned.
-- HTML5 Access disabled for some of the RDS farms managed by the broker.

Impact:
APM offers HTML5 client launch option and actually runs it if requested, although it is disabled at the backend.

Workaround:
There is no workaround at this time.

Fix:
For Horizon 7.x, the system now honors the <html5-access-disabled> flag in broker responses to disable HTML5 client for those RDS desktops and apps that have this flag set.

Behavior Change:
Before this fix, all the RDS desktops and apps were available for HTML5 client if it was installed on VCS.
Now, for those desktops and apps where HTML5 access has been deliberately disabled at the broker, only the native client option will be available.

Symptoms:
When upgrading, monitor attributes such as receive string and send string might contain escape sequences that must be processed after the upgrade. However, due to a problem introduced by the LTM policy upgrade script, this processing is not performed, resulting in monitors not functioning correctly after the upgrade.

Note: Without LTM policies in the configuration, monitors upgrade without problem.

Conditions:
-- Upgrading and rolling forward monitor configuration data.
-- LTM policy data present.

Impact:
Monitors may not work after upgrade.

Workaround:
No workaround at this time.

Fix:
This release addresses the underlying problem so the issue no longer occurs.

685344-2 : Monitor 'min 1 of' not working as expected with FQDN nodes/members

Component: Local Traffic Manager

Symptoms:
A pool with a monitor configured as 'min 1 of {...}' may be unavailable when one or more members configured with FQDN are down, rather than remain available as long as at least one pool member remains up.

Conditions:
-- Pool nodes/members are configured with FQDN.
-- At least one associated monitor is defined with the 'min 1 of {...}' feature.

Impact:
The pool may be seen as 'offline' when one or more members are down, rather than remaining available as long as a single pool member is 'UP'.

Workaround:
To configure a pool with 'min 1 of{...}', specify static pool members, do not use FQDN to configure pool members.

Fix:
A pool with FQDN configured nodes/members and specified with a monitor of 'min 1 of {...}' remains available as long as a single pool member remains up.
This issue is resolved by the FQDNv2 feature re-implementation.

685020-1 : Enhancement to SessionDB provides timeout

Component: TMOS

Symptoms:
In some cases, calls made to SessionDB never return from the remote TMM.

Conditions:
-- Using add, update, delete, and lookup commands to remote TMM.
-- SessionDB request is not returned.

Impact:
Calls made to SessionDB never return from the remote TMM.

Workaround:
None.

Fix:
The system initiates a timeout after 2 seconds. If a timeout occurs, the calling command receives a result of err==ERR_TIMEOUT.

A new sys db variable was added to enable the timeout for the iRule table command. It defaults to false. Below is the new definition followed by the tmsh command to set the value.

# Enable or disable iRule table cmd timeout override to cause all
# requests to be 'remembered' so that we do not leak them
# if subsystems fail.
[Tmm.SessionDB.table_cmd_timeout_override]
default=false
type=enum
realm=common
enum=|true|false|

Behavior Change:
A new sys db variable was added to enable the timeout for the iRule table command. It defaults to false. Below is the new definition followed by the tmsh command to set the value.

# Enable or disable iRule table cmd timeout override to cause all
# requests to be 'remembered' so that we do not leak them
# if subsystems fail.
[Tmm.SessionDB.table_cmd_timeout_override]
default=false

684414-1 : Retrieving too many groups is causing out of memory errors in TMUI and VPE

Component: Access Policy Manager

Symptoms:
Retrieving too many groups might cause out-of-memory errors in TMUI and VPE. TMUI might end up with HTTP 502 and VPE fails with HTTP 500

Conditions:
LDAP/AD server with over 20,000 groups.

Impact:
It's hard to perform LDAP/AD group mapping because there are no group names in the dialog box, which complicates work on such a large number of groups.

Workaround:
The only solution is to remove /shared/tmp/gmcache folder and use manual groupmapping.

Fix:
Retrieving too many groups no longer results in memory errors in TMUI and VPE, even on LDAP/AD servers with over 20,000 groups.

Solution Article: K70084351

---

683697-3 : SASP monitor may use the same UID for multiple HA device group members

Solution Article: K00647240

Component: Local Traffic Manager

Symptoms:
Under rare timing conditions, the SASP monitor running on one member of an HA group (failover device group) may use the same LB UID as another member of the device group.

The LB UID used to connect to the Server/Application State Protocol (SASP) Group Workload Manager (GWM) is required to be unique for each client connecting to the GWM.

As a result, only the first HA group member using the duplicated UID is able to successfully use the SASP monitor.

The SASP monitor instance running on the HA group member using the duplicated UID will fail to connect to the SASP GWM.

Conditions:
This occurs under rare timing conditions when using the SASP monitor on a BIG-IP system that belongs to an HA group.

It is possible that the necessary timing conditions may occur if the external SASP monitor daemon is forcibly restarted (such as for troubleshooting purposes).

Impact:
The SASP monitor is unable to monitor pool member availability on all members of the HA group.

Workaround:
Forcing the mcpd process to reload the configuration (as described in article K13030: Forcing the mcpd process to reload the BIG-IP configuration (https://support.f5.com/csp/article/K13030) allows recovery from this condition.

It is possible that less-intrusive measures such as restarting the external SASP monitor daemon (such as by sending a SIGTERM to the SASPD_monitor process) may also allow recovery. Due to the rare occurrence of this symptom, this solution has not been confirmed.

Fix:
The SASP monitor reliably uses a unique UID across HA group members, allowing all HA group members to successfully connect to the SASP GWM.

683683-1 : ASN1::encode returns wrong binary data

Component: Local Traffic Manager

Symptoms:
ASN1::encode returns incorrect data for certain integer values. For example, for integer 49280, ASN1::encode returns 02030000.

Conditions:
The problem happens in an implicit UTF encoding/decoding, and it is not obvious what data triggers the error.

This is because it implicitly converts the Tcl object type from byte array to string and later back to byte array, but because of the UTF de-coding algorithm, certain bytes get changed.

Impact:
The returned binary is wrong.

Workaround:
Use binary scan for the value that is incorrectly encoded by the command.

Fix:
ASN1::encode ENCODE mode now works so that it avoids the implicit type-conversion byte array to string back to byte array, which gets the original byte array changed during UTF-8 decoding.

---

---

682682-3 : tmm asserts on a virtual server-to-virtual server connection

Component: Local Traffic Manager

Symptoms:
tmm might crash when using a virtual server-to-virtual server connection, and that connection has a TCP profile with keepalive configured.

Conditions:
-- L7 virtual server-to-virtual server connection (Virtual command, cpm rule, etc.).
-- TCP profile with keepalive configured.
-- (Deflate profile.)
-- At the beginning of the connection, there is a stall for longer than the specified keepalive timer interval.
-- The received response decompresses to a size that is greater than the advertised window size on the first virtual server's TCP stack.

Impact:
Shortly after the keepalive packet is received, which then is decompressed, the assert is triggered, and tmm restarts. Traffic disrupted while tmm restarts.

Workaround:
Remove keepalive from the TCP profiles of the two virtual servers involved.

Fix:
The system now honors the current receive window size when sending keepalives, so the tmm crash no longer occurs.

Impact:
Multi bladed vCMP guest, running on a BIG-IP with SSD drives, having only one available Slot have Event Correlation disabled.

Workaround:
The following workaround does not survive ASM restart.
Thus, it has to be executed after every restart of ASM:
------------------------
# perl -MF5::ASMReady -MF5::Cfg -e 'while (! F5::ASMReady::is_asm_ready()) { print "Waiting for ASM to be ready.\n"; sleep 5; }; print "ASM is ready, patching Event Correlation cfg file\n"; F5::Cfg::cfg_set_config_item(qw{/etc/ts/correlation/correlation.cfg}, qw{General}, qw{Idle}, 0)'

# pkill -f correlation
------------------------

Event Correlation should start with in ~15 seconds, after the execution of this workaround:
------------------------
# ps -elf | grep correlation

0 S root ... /usr/share/ts/bin/correlation

682213-3 : TLS v1.2 support in IP reputation daemon

Solution Article: K31623549

Component: TMOS

Symptoms:
The IP reputation daemon opens SSL connections to the Webroot BrightCloud server using TLS 1.0 protocol.

Conditions:
This occurs when using IP reputation.

Impact:
Because IP reputation services are used to accept/deny connections to critical business applications, there might be concerns about the service. Also some configurations might require that all transactions exfiltrating a PCI-controlled environment leverage secure protocols and ciphers, which won't be the case for IP reputation services.

Workaround:
None.

Fix:
Webroot updated BrightCloud servers to support TLS 1.2. This is additional support. To preserve backward compatiblity, the servers support TLS 1.0, TLS 1.1, TLS 1.2, SSL 2.0 and SSL 3.0.

In addition, this software version supports TLS 1.2 on the client side by customizing the SDK used by the IP reputation daemon.

---

681109-2 : BD crash in a specific scenario

Solution Article: K46212485

Component: Application Security Manager

Symptoms:
BD crash occurs.

Conditions:
A specific, non-default configuration with specific traffic.

The issue is much more likely to occur when the policy is not tuned correctly, in which case you might receive a potentially huge number of false positive attack signature matches on that payload. The crash might then occur if there is a subsequent 'Parameter value does not comply with regular expression' violation on that same payload.

For example, nothing prevents you from incorrectly associating a Content-Type and <type-value> with a Request Body Handling parser that is not designed to parse that type of data, such as the following:
  Content-Type :: *xml* :: form-data

This configuration is likely to result in a very long list of false-positive attack signatures. Because of the big message generated, The regex violation which is also likely to happen on the payload cannot be added to the filled message, which causes the crash.

Impact:
Failover, traffic disturbance.

Workaround:
In order to prevent this, correctly configure the header-based-content-profile property on URLs for cases where an unusual header requires a specific, potentially unexpected parsing mechanism.

A correctly configured header-based-content-profile property on URLs appears as follows:

In URL Properties, the Header-Based Content Profiles section of the wildcard URL is by default applying the value and content signature. Here, you can associate Content-Type with <type-value> with <parser-type>. By default, the correct definitions are as follows:
 Content-Type :: *form* :: Form Data
 Content-Type :: *json* :: JSON
 Content-Type :: *xml* :: XML

Fix:
Added a check to prevent a crash in a specific scenario.

680850-1 : Setting zxfrd log level to debug can cause AXFR and/or IXFR failures due to high CPU and disk usage.

Solution Article: K48342409

Component: Global Traffic Manager (DNS)

Symptoms:
Enabling debug logging on zxfrd (DNSX) can result in excessive CPU and disk usage, as well as errors during DNS AXFR or IXFR processing.

Conditions:
log.zxfrd.level is set to debug by running the following command: tmsh modify sys db log.zxfrd.level value debug

Impact:
IXFRs or AXFRs may fail and be rescheduled due to high CPU usage by zxfrd, which causes it to fail to process data packets during a transfer.

Workaround:
To avoid this issue, do not set log.zxfrd.level to debug.

Fix:
With this change, the dump to /var/tmp/zxfrd.out occurs only when a new db variable, dnsexpress.dumpastext, is set to true. This enables turning on logging for debug without consuming all the CPU and disk necessary to dump packets and zone contents.

Note: Setting this value to true will cause the information to be dumped to stderr, which reveals the original issue, potentially causing transfer failures and high system resource usage. F5 recommends that you enable it only when directed to do so by F5 support staff.

Behavior Change:
Previously, setting the zxfrd log level to debug caused all AXFR and IXFR requests and responses to be logged to /var/tmp/zxfrd.out. Doing so also caused the contents of all zones to be dumped, as text, to /var/tmp/zxfrd.out when the database was saved.

This was extremely CPU-, memory-, and disk-intensive. The CPU load could cause zxfrd to fail to process transfer data packets in a timely fashion, which could cause the master DNS server to close the connection.

With this fix, setting log.zxfrd.level debug no longer outputs this information.

Although it is not generally useful to output the contents of the transfer packets or the contents of the database, if this information is required for troubleshooting or information-verification purposes, you can set the new db variable: dnsexpress.dumpastext.

Note: Setting this value to true will cause the information to be dumped to stderr, which reveals the original issue, potentially causing transfer failures and high system resource usage. F5 recommends that you enable it only when directed to do so by F5 support staff.

678416-2 : Some tmm/umem_usage_stat counters may be incorrect under memory pressure.

Component: Local Traffic Manager

Symptoms:
After the BIG-IP system experiences severe memory pressure, the 'allocated' and 'max_allocated' counters from the tmm/umem_usage_stat table incorrectly show extremely high values.

Conditions:
The BIG-IP system experiences enough memory pressure that slabs are transferred between threads.

Impact:
The 'allocated' and 'max_allocated' counters from the tmm/umem_usage_stat table do not reflect actual values. However, there is no functionality issue as a result. This is a cosmetic issue only.

Workaround:
None.

Fix:
The system now manages better under memory pressure so that the tmm/umem_usage_stat counters correctly reflect actual values.

678293-1 : Uncleaned policy history files cause /var disk exhaustion

Component: Application Security Manager

Symptoms:
There are hundreds of policy history files for non-existent policies stored under /ts/dms/policy/policy_versions, which might cause /var disk exhaustion.

Conditions:
There are hundreds of policy history files for non-existent policies stored under /ts/dms/policy/policy_versions.

Two possible causes might explain what caused the history files to be copied:
-- The device was synchronized from itself.
-- There was a UCS loaded on the device.

Impact:
/var disk usage is high.

Workaround:
Use the following one-liner to find unreferenced policy history files that can be deleted:

----------------------------------------------------------------------
perl -MData::Dumper -MF5::DbUtils -MFile::Find -e '$dbh = F5::DbUtils::get_dbh(); $sql = ($dbh->selectrow_array(q{show tables in PLC like ?}, undef, q{PL_POLICY_VERSIONS})) ? q{select policy_version, policy_id from PLC.PL_POLICY_VERSIONS} : q{select revision, policy_id from PLC.PL_POLICY_HISTORY}; %known_history_files = map { (qq{$_->[1]/$_->[0].plc} => 1) } @{$dbh->selectall_arrayref($sql)}; find({ wanted => sub { next unless -f $_; $_ =~ m|/policy_versions/(.*)$|; if (! $known_history_files{$1}) { print qq{$_\n} } }, no_chdir => 1, }, q{/ts/dms/policy/policy_versions});'
----------------------------------------------------------------------

Manually verity the file list output. If it seems correct, you can then delete the files by piping the output into 'xargs rm'.

In addition, you can delete the following file: /var/ts/var/install/recovery_db/conf.tar.gz.

Workaround:
Do not encapsulate APM tunnel in an IPsec tunnel. (The APM tunnel has its own TLS.)

Fix:
APM tunnel and IPsec over IPsec tunnel now correctly accepts isession-SYN connect packets.

---

677457 : HTTP/2 Gateway appends semicolon when a request has one or more cookies

Component: Local Traffic Manager

Symptoms:
With an HTTP/2 profile, a virtual server on a BIG-IP system receives requests and handles cookies converting those into a cookie-string. The BIG-IP system concatenates the cookie pairs with semicolon (%3B) and a space (%20) in the cookie-string. This delimiters pair also is appended to the last cookie pair.

Conditions:
HTTP/2 profile is configured on a virtual server and a request contains one or more cookies.

Impact:
The request forwarded to a backend server contains an extra semicolon at the end of cookie-string.

Workaround:
Use an iRule to remove an extra delimiter if it negatively impacts backend server performance.

For example:

when HTTP_REQUEST {
if {[HTTP::header value "Cookie"] contains ";"}
{
set new_header [string range [HTTP::header "Cookie"] 0 end-2]
log local0.notice "$new_header"
HTTP::header replace "Cookie" $new_header
}
}

Fix:
Virtual server with HTTP/2 profile no longer appends extra delimiter to a cookie-string when it forwards the request to HTTP/1.x backend server.

677119 : HTTP2 implementation incorrectly treats SETTINGS_MAX_HEADER_LIST_SIZE

Component: Local Traffic Manager

Symptoms:
When HTTP2 connection's parameters are negotiated, either side may report about its limits in SETTINGS type frame where one of the parameters SETTINGS_MAX_HEADER_LIST_SIZE determines a maximum size of headers list it is willing to accept. BIG-IP incorrectly interchanged this parameter with another one called SETTINGS_HEADER_TABLE_SIZE, limiting value of the former one to 32,768.

Conditions:
HTTP2 is configured and an opposite endpoint (user agent using HTTP2 protocol) tries to set SETTINGS_MAX_HEADER_LIST_SIZE to a value above 32,768.

Impact:
BIG-IP doesn't accept the value and terminates the connection using GOAWAY frame with PROTOCOL_ERROR as a reason.

Fix:
BIG-IP no longer generates an error due to this issue and allows value for SETTINGS_MAX_HEADER_LIST_SIZE to exceed 32,768.

673463-2 : SDD v3 symmetric deduplication may start performing poorly after a failover event

Solution Article: K68275280

Component: Wan Optimization Manager

Symptoms:
In certain high availability (HA) configurations and after performing specific maintenance tasks involving failovers, SDD v3 symmetric deduplication may start performing poorly for some file transfers.

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

1) A BIG-IP HA configuration is deployed on each side of the WOM tunnel.
2) Symmetric deduplication is configured to use the SDD v3 codec.
3) The far side BIG-IP HA configuration (from the perspective of the client performing the download) is failed over.
4) Clients attempt to download files that had previously been transferred through the BIG-IP units.

Impact:
Symmetric deduplication is severely impacted (virtually no hits) for files that had previously been transferred through the units. This causes the amount of data transmitted over the WAN to increase. Files that were not transferred previously through the units are not affected by this issue.

Workaround:
To eliminate the impacted symmetric deduplication condition, restart the receiving (i.e., the near) side.

Fix:
SDD v3 symmetric deduplication no longer performs poorly after a failover event.

673399-1 : HTTP request dropped after a 401 exchange when a Websockets profile is attached to virtual server.

Component: Local Traffic Manager

Symptoms:
The client sends a GET request with switching protocols and the server responds with a 401. Subsequent GET request from client is dropped.

Conditions:
HTTP and Websocket profiles are attached to the virtual server. The client sends a GET request with switching protocols indicating upgrade to Websockets, and the server responds with a 401. Subsequent GET request from client is dropped.

Impact:
Connection is reset.

Workaround:
Disable Websockets profile on the virtual server.

673129 : New feature: revoke license

Component: TMOS

Symptoms:
A different license is required for each Virtual Edition (VE) instance.

Conditions:
Creating new instances of VE.

Impact:
Cannot reuse an existing VE license.

Workaround:
None.

Fix:
For Virtual Edition (VE) BIG-IP systems, licenses can now reused by other VE instances by revoking an active license on one and installing it on another.

Behavior Change:
Revoke license is a new feature so that licenses can be reused for other virtual edition configurations.

To revoke a license using tmsh, run the following command:
 tmsh revoke sys license registration-key <reg-key-number>

The system responds with the following confirmation prompt:
 Revoking the license will return this BIG-IP to an unlicensed state. It will stop processing traffic. Are you sure? Y/N:

When you type y, the system revokes the license and returns a response similar to the following:
 License successfully revoked
 [root@bigip11:LICENSE INOPERATIVE:Standalone] config # Jul 17 12:04:28 bigip11 emerg mcpd[5144]: 01070608:0: License is not operational (expired or digital signature does not match contents).

673075-1 : Reduced Issues for Monitors configured with FQDN

Component: Local Traffic Manager

Symptoms:
Monitors configured using FQDN might experience several edge cases in some deployment environments. For example, you might experience issues with FQDN-configured monitors when used in environments with volatile/unstable DNS servers, or when network configuration causes ICMP packets from an unreachable DNS server to be non-routable back to 'bigd'. In such cases, the monitor may experiences delay in rotating to the next available DNS server. This is due to complex edge cases that exist within the initial FQDN monitor implementation, where anomalous behavior is aggravated through some network configurations.

Conditions:
Monitors are configured using FQDN, and one-or-more environment conditions exist such as: Unstable DNS servers (i.e., 'flapping' DNS), or the network configuration causes ICMP packets from an unreachable DNS server to be non-routable back to 'bigd'.

Impact:
The monitor will not be updated with information from the (new) DNS server when the previous DNS server becomes unavailable. Other monitor behavior will continue to function normally.

Workaround:
In some cases network configuration can be changed to avoid these edge cases, such as: Ensuring stable DNS servers with only periodic rollovers to backup DNS servers; ensure network ICMP packets are routable back to 'bigd'. Alternatively, monitors may be configured without using FQDN.

Fix:
Monitors configured using FQDN behave as expected in volatile environments, such as those with flapping DNS servers and where ICMP packets for unreachable DNS servers are non-routable back to 'bigd'.

672988-2 : 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.

---

672250-1 : SessionDB update from ApmD with large volume fails

Component: Access Policy Manager

Symptoms:
While writing large amounts of data to sessionDB using memcache API, the write operation fails with partial write.

Conditions:
Large volumes data writing to SessionDB via memcache API.

Impact:
All worker threads performing authentication eventually get locked down. Session watchdog thread eventually makes a forced abort to recover from the situation. ApmD restarts in this situation.

Workaround:
Control write to sessionDB with a smaller data size.

Fix:
Partial write failure has been fixed, by writing remaining part(s) of query results in several iteration(s), until entire result is written.

---

672040-3 : Access Policy Causing Duplicate iRule Event Execution

Component: Access Policy Manager

Symptoms:
iRule event gets triggered twice in clientless mode when access policy is executed.

Conditions:
This only occurs when using iRule in clientless-mode.

Impact:
HTTP_REQUEST event is logged twice in /var/log/ltm.

See below example:

when HTTP_REQUEST {
  HTTP::header insert {clientless-mode} 1
  set myCount [expr {$myCount + 1}]
  log local0. "Count is $myCount"
}

LTM logs:
-----------

Jul 3 12:29:35 BIG-IP10002-vcmp2 info tmm1[23908]: Rule /Common/test_irule <HTTP_REQUEST>: Count is 1
Jul 3 12:29:36 BIG-IP10002-vcmp2 info tmm1[23908]: Rule /Common/test_irule <HTTP_REQUEST>: Count is 2


When this iRule is used, you will see duplicate HTTP_REQUEST with increased count in logs. If this count is used in further calculation, it gives you incorrect result.

Fix:
HTTP_REQUEST iRule event is no longer executed multiple times when using APM clientless-mode.

672008-1 : NUL character inserted into syslog message when system time rolls over to exactly 1000000 microseconds

Solution Article: K22122208

Component: Local Traffic Manager

Symptoms:
Remote syslog logging destinations configured for RFC5424 format might receive malformed timestamp values if the log message is sent when clock rolls over to 1,000,000 microseconds exactly. The resulting log message will have a NUL character appended to the microseconds value in the log's timestamp field.

Example:
Correct timestamp: 2003-08-24T05:14:15.000000-07:00
Malformed timestamp: 2003-08-24T05:14:14.100000\00-07:00

Conditions:
-- syslog destination configured for RFC5424 format.
-- Sending log message when clock rolls over to 1,000,000 microseconds.

Impact:
Some syslog collectors may fail to parse the message, resulting in incorrect log entry or warning.

Workaround:
Change syslog destination format to use RFC3164, which does not include microsecond resolution in timestamp fields.

Fix:
The timestamp field is now formatted correctly for microseconds and seconds values. Seconds now correctly increment when microseconds equal 1,000,000.

671935-2 : Possible ephemeral port reuse.

Solution Article: K64461712

Component: Local Traffic Manager

Symptoms:
When selecting server-side source ports, the BIG-IP system favors ephemeral ports in the upper range.

Conditions:
Source ports, different from the client side, may be reselected. This is always the case when the virtual server's 'source-port change' option is enabled.

Impact:
If server connections are in the TIME_WAIT state and connection recycling is not configured, the server might reset the connection, reusing ports.

Workaround:
Disable the virtual server's 'source-port change' option to use the same source port as the connecting client.

Fix:
Now, even when the virtual server's 'source-port change' option is enabled, the system uses the same source port as the connecting client.

671920-1 : Accessing SNMP over IPv6 on non-default route domains

Component: TMOS

Symptoms:
The SNMP daemon cannot send traps to a non-default route domain destination. However, it can respond to SNMP requests over from a client that is accessed through a non-default route domain path for IPv4. For IPv6 this does not work.

Conditions:
SNMP access over IPv6 on a client accessed through a non-default route domain does not work.

Impact:
Access to SNMP must be through default route domain for IPv6.

Fix:
With this bug fix you can access SNMP from an IPv6 client on a non-default route domain. There is no plan to allow traps to be delivered to destinations on a non-default route domain.

---

671675-1 : Centralized Management Infrastructure: asm_config_server restart on device group change

Component: Application Security Manager

Symptoms:
If device is moved from one ASM sync enabled device group immediately to another ASM sync enabled device group the ASMConfig relay listener restarts, and artifacts are left over from the previous device group that could cause undesired config synchronization if it returns to the original device group

Conditions:
A device is moved from one ASM sync enabled device group immediately to another ASM sync enabled device group.

Impact:
ASMConfig relay listener restarts, and artifacts are left over from the previous device group that could cause undesired config synchronization if it returns to the original device group

Workaround:
Wait 30 seconds between leaving an ASM enabled device group before joining a different one.

Fix:
Successive changes to ASM sync enabled device group are handled correctly.

671627-1 : HTTP responces without body may contain chunked body with empty payload being processed by Portal Access.

Solution Article: K06424790

Component: Access Policy Manager

Symptoms:
Some HTTP responses do not contain any body. For instance, responses with status codes 1xx, 204, or 304 must not include body. Portal Access adds 'Transfer-Encoding: chunked' header and may add chunked body with empty payload to such responses.

Conditions:
HTTP response without body processed by Portal Access

Impact:
Most browsers ignore invalid 'Transfer-Encoding' header and/or body for responses which must not include body at all. And yet, some traffic validators may refuse to pass invalid responses.

Workaround:
Use an iRule to remove 'Transfer-Encoding' header and/or body from HTTP responses with status codes 1xx, 204, and 304.

Fix:
Now Portal Access does not add invalid 'Transfer-Encoding' header and/or body to responses which have no body.

---

671597-1 : Import, export, copy and delete is taking too long on 1000 entries policy

Component: Access Policy Manager

Symptoms:
Huge policies with 10^3 items are impossible to import, export and copy.

Conditions:
When access policy has 1000+ entires.

Impact:
Import, export and copy are abandoned or fail due to out of memory condition.

Workaround:
Use ng_export, ng_import and ng_profile rather than UI to import/export.

Fix:
ng_export speed has been improved 5 times
ng_import and ng_profile are working 50 times faster because of avoiding denormalisation and optimisation

ng_export is still should be used from the console.

671228-1 : Multiple FQDN ephemeral nodes may be created with autopopulate disabled

Component: Local Traffic Manager

Symptoms:
Multiple FQDN ephemeral nodes may be created unexpectedly if an FQDN node is configured with autopopulate disabled, the DNS server returns multiple address records for the FQDN, and bigd is restarted.

Conditions:
This may occur when:
1. An FQDN node is configured with autopopulate disabled.
2. The DNS server returns multiple address records for the FQDN.
3. There is a pool configured to use the FQDN node.
4. bigd is restarted (such as when the system goes offline or tmm restarts).

Impact:
Multiple FQDN ephemeral nodes may be created unexpectedly.

Workaround:
Configure the FQDN node with autopopulate enabled.

Fix:
Multiple FQDN ephemeral nodes are no longer created unexpectedly if an FQDN node is configured with autopopulate disabled, the DNS server returns multiple address records, and bigd is restarted. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

671149-3 : Captive portal login page is not rendered until it is refreshed

Component: Access Policy Manager

Symptoms:
Sometimes Edge Client shows an error page for captive portal-redirected URLs.

Conditions:
Some captive portal pages use cloud-based authentication and network management. Such captive portals rely on several HTTP redirects and/or HTML (auto-refresh). Sometimes Edge Client fails to download the page/content from the redirected URL. In such scenarios, a full browser re-attempts and successfully downloads and displays the page, but Edge Client does not re-attempt and shows an error page.

Impact:
For the locked client, an APM end user has no access to the internet until captive portal authentication is performed and the Network Access (VPN) tunnel is created.

Workaround:
None.

Fix:
Edge Client now has a retry mechanism to access and display captive portal login pages in case the first attempt fails.

670816-2 : HTTP/HTTPS/TCP Monitor response code for 'last fail reason' can include extra characters

Solution Article: K44519487

Component: Local Traffic Manager

Symptoms:
An HTTP/HTTPS/TCP monitor response code may contain extraneous trailing characters, such as: 'Response Code: 200 (OKxxx)' where the server response code 'OK' is appended with unrelated characters 'xxx', when the server does not include a carriage-return/line-feed after the response status line.

Conditions:
An HTTP/HTTPS/TCP monitor is configured with a receive string, and the server does not include a carriage-return/line-feed in the TCP segments that match the receive string.

Impact:
The monitor status code displays the correct server response code, but with extraneous trailing characters appended. The monitor continues to function and respond to status changes as expected.

Workaround:
Configure HTTP/HTTPS/TCP servers to return a response that includes a carriage-return/line-feed after the response status line and before the receive string.

Fix:
HTTP/HTTPS/TCP monitor response code for 'last fail reason' no longer contains extraneous trailing characters when the server does not include a carriage-return/line-feed in the TCP segments that match the receive string.

670405-4 : K20486351: glibc vulnerability CVE-2017-1000366:

Component: TMOS

Symptoms:
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. (CVE-2017-1000366)

Conditions:
crafted LD_LIBRARY_PATH values to manipulate the heap/stack

Impact:
This vulnerability allows unauthorized disclosure of information, unauthorized modification, and disruption of service.

Workaround:
To mitigate this vulnerability, you should permit management access to F5 products only over a secure network and restrict command line access for affected systems to trusted users.

Fix:
upgrade to software with fix

670400-3 : SSH Proxy public key authentication can be circumvented in some cases

Component: Advanced Firewall Manager

Symptoms:
SSH Proxy public key authentication might be circumvented in some cases, allowing a user without the appropriate private key in to the back-end end SSH server.

Conditions:
Public key authentication is being used to authenticate users.

Note: This issue affects only public key authentication, so if additional forms of authentication are being used, the additional security that they provide will not be impacted.

Impact:
Unauthorized access.

Workaround:
A suggested workaround is to configure the back-end SSH server to require 2-factor authentication, or 3-factor authentication. This can be done by adding both publickey+password and publickey+keyboard-interactive as Required Authentications in the configuration file for the back-end SSH server.

See the list below of supported client method orders. Also, keep in mind that the back-end server must support all 3 authentication methods (public-key, password, and keyboard-interactive), as an existing constraint of the current SSH proxy functionality.
 
One cosmetic item to note is that, when multi-factor authentication is used, regardless of the result of the validity check of the public-key, the SSH proxy will report a 'failed' authentication to the client. However, the returned 'failed' code is merely cosmetic: the actual result of the validity check is what is used to determine whether or not the authentication succeeded.

-------
Supported client method orders:
 
publickey,keyboard-interactive
publickey,password
publickey,keyboard-interactive,password
publickey,password,keyboard-interactive
 
Any other combination of authentication methods will fail.

Fix:
Implemented stricter error handling in authentication checking.

670011-2 : SSL forward proxy does not create the server certchain when ignoring server certificates

Component: Local Traffic Manager

Symptoms:
Forward proxy not working correctly when the server certificates are ignored. SSL forward proxy does not create the server certchain when ignoring server certificates, this prevents the client side from trusting the server cert and the SSL handshake hangs and fails after timeout.

Conditions:
-- SSL forward proxy or SSL intercept is configured.
-- Ignore server certificate configured in the server SSL profile.

Impact:
Client cannot establish SSL connection with server due to SSL handshake always timing out.

Workaround:
None.

Fix:
The system now generates the server certchain (even when the server SSL profile ignores server certificates) and passes it to the client SSL, so that the client SSL can forge the cert and finish the SSL handshake.

669974-1 : Encoding binary data using ASN1::encode may truncate result

Solution Article: K90395411

Component: Local Traffic Manager

Symptoms:
When using ASN1::encode to encode one or more values, and where the encoding of any of these values results in a representation containing a NUL ('\x0') byte, the overall result that is presented to the iRule does not include the entire set of encoded values and is truncated at the first NUL byte.

Conditions:
-- Using ASN1::encode with binary values (e.g., INTEGER).
-- Encoded results contain a NUL ('\x0') byte.

Impact:
Encoding results in the wrong/truncated value.

Workaround:
It is possible to encode the problematic values using an alternative method.

Fix:
ASN1::encode now correctly encodes binary values.

---

669888-2 : No distinction between IPv4 addresses and IPv6 subnet ::ffff:0:0/96

Component: TMOS

Symptoms:
The BIG-IP does not differentiate between IPv4 addresses (such as 1.2.3.4) and IPv6 addresses in the prefix ::ffff:0:0/96 (such as ::ffff:102:304, also written ::ffff:1.2.3.4). If you enter such an IPv6 address, the equivalent IPv4 address will be rendered and used.

Conditions:
Any attempt to use an IPv6 address in that subnet.

Impact:
The BIG-IP system will operate as if you entered the IPv4 address.

Workaround:
No workaround at this time.

Fix:
The differing addresses now are handled correctly. For most modules, this does not change the functionality at all. AFM is one exception; IPv6 traffic in the ::ffff:0:0/96 subnet will be treated differently than IPv4 traffic.

669459-2 : Efect of bad connection handle between APMD and memcachd

Component: Access Policy Manager

Symptoms:
When a connection handle (fd) between apmd and memcachd gets bad (someone else is using or already closed by memcachd), all worker threads gets locked out. A cleaner thread then restart APMD with an assert.

Conditions:
This is difficult to reproduce. It happens if one or more connection handle between apmd worker thread and memcachd gets misused.

Impact:
APMD gets locked down , eventually restart with a core.

Workaround:
None.

Fix:
Communication between APMD and TMM has been improved to be more tolerant of error conditions.

Component: Fraud Protection Services

Symptoms:
TMM core when server responds fast with server responses such as 404.

Conditions:
-- FPS gets a request with a WebSafe URL (usually global URL - declared by signatures update).
-- Server response is fast (based on URL/headers).
-- FPS need to take some action on response.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
FPS now handles these conditions without a tmm crash.

---

669359 : WebSafe might cause connections to hang

Component: Fraud Protection Services

Symptoms:
In a loaded environment, FPS might free a connection context without cleaning up the state.

Conditions:
This occurs in a loaded environment (xoff events present).

Impact:

669341 : Category Lookup by Subject.CN will result in a reset

Component: Access Policy Manager

Symptoms:
Category Lookup Agent is unable to find the Subject.CN, so it initiates an SSL Handshake failure.

==> /var/log/apm <==
crit tmm[11181]: 01790602:2: [C] 10.20.100.1:11980 -> 10.11.10.101:443: (ERR_NOT_FOUND) Error processing URL Classification query from CatEngine

Conditions:
Category Lookup agent configured to use Subject.CN. May also apply if a Category Lookup agent is configured to use SNI, but the client does not send an SNI, resulting in the agent trying to use the Subject.CN.

Impact:
Cannot use Subject.CN as a data source for category lookup agent.

Workaround:
None.

Fix:
The category lookup agent is now able to find the Subject.CN.

669288-3 : Cannot run tmsh utils unix-* commands in Appliance mode when /shared/f5optics/images does not exist.

Solution Article: K76152943

Component: TMOS

Symptoms:
From tmsh, running util unix-ls /var/log fails with the following error:

exception: (Failed to canonicalize "/shared/f5optics/images") (util/RealpathHelper.cpp, line 49), continuing...
Data Input Error: /var/log is not an accessible directory for the current mode.

Conditions:
-- A BIG-IP system configured for Appliance mode.
-- Upgrading from a pre-v12.x to v12.x or later.
-- Using a platform that does not have a /shared/f5optics/images directory.

These include the following BIG-IP blades and appliances:
B4400, i4x00, i10x00, i2x00, i7x00, i5x00

Impact:
There is no shell access to the file system when the BIG-IP system is in Appliance mode. This is the intended purpose of Appliance mode. Therefore, unix-* commands are the only way to list directories, and perform other operations specific to the operating system.

Workaround:
To work around this issue, create the /shared/f5optics/images directory. To do so, do the following:

 1. Boot the BIG-IP system into single-user mode.

 2. Create the directory /shared/f5optics/images with the following command:
  mkdir -m 777 -p /shared/f5optics/images.

 3. Reboot the BIG-IP system, and allow it to start up normally.

Fix:
The reported exception does not occur, and unix-* commands commands issued in Appliance mode run as expected.

669255-2 : An enabled sFlow receiver can cause poor TMM performance on certain BIG-IP platforms

Solution Article: K20100613

Component: TMOS

Symptoms:
If the BIG-IP configuration includes at least one enabled sFlow receiver, certain platforms will experience poor TMM performance. Symptoms will include one or more of the following:

- Higher than normal ping latency to the BIG-IP Self-IP addresses.
- Higher than normal latency for applications flowing through BIG-IP virtual servers.
- TMM clock advanced messages in the /var/log/ltm file.
- Continuous activation and then quick deactivation of the idle enforcer for all TMM instances in the /var/log/kern.log file.

Conditions:
The BIG-IP configuration must include at least one enabled sFlow receiver (it doesn't matter whether this is reachable or not) and the platform type must be one of the following:

- BIG-IP i10000 series
- BIG-IP i7000 series
- BIG-IP i5000 series
- BIG-IP i4000 series
- BIG-IP i2000 series
- VIPRION B4450 blade

Impact:
The BIG-IP system operates at a suboptimal performance level.

Workaround:
If the sFlow receiver is not strictly necessary for the correct functioning of your deployment, this can be disabled or removed to work around the issue.

Fix:
Performance is no longer degraded on certain platforms when the configuration includes enabled sFlow receivers.

669154-1 : Creating new invalid SAML IdP configuration object may cause tmm restart in rare cases.

Component: Access Policy Manager

Symptoms:
Adding new SAML IdP configuration object containing empty attribute values via tmsh may cause tmm to restart.

Conditions:
New SSO SAML configuration contains one or more attribute values containing a session variable, following by another empty value "", for example:

multi-values { "%{session.ad.last.attr.name}" "" }

Note: This is not a valid configuration: empty values must not be provided in the list of SAML attributes.

Impact:
TMM may restart when new configuration is added. Traffic disrupted while tmm restarts.

Workaround:
Remove empty attribute values from configuration.

Fix:
SAML object validation has been improved so that empty SAML SSO object attribute values will no longer be accepted.

---

669025-1 : Exclude the trusted anchor certificate in hash algorithm selection when Forward Proxy forges a certificate

Solution Article: K11425420

Component: Local Traffic Manager

Symptoms:
SSL Forward Proxy signs a forged certificate with a hash algorithm. This selected hash algorithm is the weakest algorithm from the certificates in the server certificate chain except the self-signed certificate.

Some of the intermediate CA certificates in the cert chain use the SHA1 hash algorithm. This kind of intermediate CAs usually is are the BIG-IP system's ca-bundle. BIG-IP receives the cert chain including the intermediate CA and forges the cert with SHA1, which is rejected by some web clients.

Conditions:
-- The BIG-IP system is configured to use SSL Forward Proxy or SSL Intercept.
-- Some intermediate CA in the web server's cert chain is using a weak algorithm like SHA1 to sign certificates.
-- The web client rejects the weak-algorithm-signed certificate.

Impact:
Clients cannot access the web server due to SSL handshake failure.

Workaround:
There is no workaround at this time.

Fix:
This fix excludes trusted CA certificates in hash algorithm selection. This may prevent forged certificate from using SHA1 hash algorithm.

668883 : FQDN pool member status may become out-of-sync when enabled/disabled through GUI

Component: Local Traffic Manager

Symptoms:
After toggling enable/disable on an FQDN pool member through the GUI, an FQDN pool member status may become 'out-of-sync', and the pool member might process connections opposite to its status. Specifically: 'disabled' might accept connections, and 'enabled' might not accept connections. In this state, the FQDN pool member appears to be exactly 'one-message-behind' for an enable/disable status change made in the GUI.

The FQDN pool member status for enabled/disabled is always correctly displayed in the GUI and in tmsh, and behavior is correctly restored after a system reboot. Other pool members are unaffected.

Conditions:
-- BIG-IP systems configured for high availability (HA).
-- At least three members within an FQDN pool.
-- Use the GUI to toggle enable/disable state on a FQDN pool member.

Impact:
The FQDN pool member does not correctly participate in receiving connections to the pool when in this error state. Other pool members remain unaffected.

Workaround:
Change FQDN pool to statically assign members.

Fix:
Toggling FQDN pool member between 'enable/disable' correctly changes that member's participation for accepting connections within its parent pool. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

Conditions:
-- BIG-IP DNS/GTM is licensed and provisioned.
-- BIG-IP DNS/GTM links are configured.
-- Trying to view the GTM link graphs in the GUI.

Impact:
Unable to view BIG-IP DNS/GTM link graphs.

Workaround:
None.

Fix:
The GTM graphs are available as expected.

Impact:
The bigd process might consume excessive CPU resources for for various amounts of time.

Single monitor probes might fail. Depending upon the timing of these failures, it might be possible to see monitor flapping when multiple probes for a specific monitored object happen to fail.

Workaround:
None.

Fix:
An issue was resolved where the bigd process might consume excessive CPU resources or monitor probes might be erroneously marked as failed.

---

668521-2 : Bigd might stall while waiting for an external monitor process to exit

668419-1 : ClientHello sent in multiple packets results in TCP connection close

Solution Article: K53322151

Component: Local Traffic Manager

Symptoms:
When the BIG-IP system receives ClientHello messages in multiple fragments, and the first fragment length is smaller than 8 bytes, SSL might process it as a non-SSL packet.

Conditions:
-- The system receives ClientHello messages in multiple fragments.
-- The first fragment length is smaller than 8 bytes.

Impact:
SSL might process the first fragment as a non-SSL packet, and discard it, and then tear down the TCP connection.

Workaround:
None.

Fix:
Now, if the system receives the ClientHello message in multiple fragments, and the first fragment is smaller than 8 bytes, the system waits for the whole SSL packet to arrive before processing it.

668129-1 : BIG-IP as SAML SP support for multiple signing certificates in SAML metadata from external identity providers.

Component: Access Policy Manager

Symptoms:
Certain SAML implementations support configuration of multiple signing certificates to be used for signing SAML messages. In these deployments different signing certificates could be used when certificate rotation takes place. Until now BIG-IP as SP only supported single signing certificate from external IdPs.
When certificate rotation happens on external IdP, BIG-IP signing verification certificates have to be updated.

Conditions:
External IdP advertises multiple signing certificates in SAML metadata.

Impact:
When external IdP starts using new signing certificate previously advertised in metadata, authentication on BIG-IP as SAML SP will fail until administrator adjusts configuration to specify new signature validation certificate on appropriate SAML IdP connector object.

Workaround:
Signing certificates on BIG-IP as SAML SP can be reconfigured manually.

Fix:
BIG-IP as SP now supports multiple signing certificates advertised by external identity providers.

Component: Fraud Protection Services

Symptoms:
1. Create fps profile with a "Additional function to be run before JavaScript load" (BLFN) configured.
2. Clone this profile.
3. In the cloned profile choose another profile to defaults from (where there is no BLFN).
4. Save configuration.

Conditions:
- Current profile has a BLFN configured.
- New parent profile has no BLFN.

Impact:
The original BLFN is still configured on the profile (should have inherited the empty BLFN from parent profile).

Workaround:
1. Use tmsh.
2. Refresh before save.

Fix:
Correct BLFN inheritance logic in GUI.

---

667872-1 : Websafe's 'Apply cookies to base domain' feature doesn't work for non standard ports

Component: Fraud Protection Services

Symptoms:
'Apply cookies to base domain' feature doesn't work for non standard ports.

Conditions:
'Apply cookies to base domain' is enabled and
connection is over non-standard ports (not 80, 443, etc.).

Impact:

667560-3 : FQDN nodes: Pool members can become unknown (blue) after monitor configuration is changed

Solution Article: K69205908

Component: Local Traffic Manager

Symptoms:
A pool member configured through an FQDN node and which has multiple associated monitors may become unknown (blue) after a monitor rule change to one of its associated monitors. The expected behavior is that the node should remain 'green' if monitoring is successful with the new rule, but the node may become unknown (blue) until bigd is restarted.

Conditions:
A pool member is configured through an FQDN node, and has multiple associated monitors, and a monitor rule change is made to one of the associated monitors.

Impact:
The pool member status correctly reflects whether monitoring is successful (green) or the pool member is unknown (blue), but the changed monitor rule may not take effect until bigd is restarted.

Workaround:
When making changes to a monitor rule associated with a pool member configured through FQDN, verify the node remains monitored (green or checking), or restart bigd. Alternatively, change monitor rules within the configuration file, and reload the configuration.

Fix:
Pool members configured through FQDN nodes and with multiple associated monitors continue to be monitored after a monitor rule change to one of the associated monitors. This issue is resolved by the FQDNv2 feature re-implementation in this version of the software.

667404-2 : Fragmented IP over IPsec tunnels might capture mcp flows and provoke restarts

Solution Article: K77576404

Component: TMOS

Symptoms:
If fragmented IP packets match an IPsec policy, then get forwarded to another tmm for actual processing, the flow lookup might accidentally grab a stale flow_key for another connflow, including internal MCP flows. When that happens, if IPsec does tunnel those flows, internal MCP heartbeats later miss and cause tmm restarts.

Conditions:
-- Packet fragmentation.
-- Packets are serviced by IPsec due to a matching policy for those packets.

Impact:
Tmm restarts. Traffic disrupted while tmm restarts.

Workaround:
You can prevent this using either of the following methods:
-- If you can, arrange that fragmented packets are re-assembled before reaching IPsec policy handling.
-- Modify MTU configuration so fragmentation does not happen.

Note: There is no mitigation when fragmented packets reach IPsec and need forwarding from one tmm to another.

Fix:
Now fragmented packets are handled correctly, and other flows cannot experience interference.

667278-3 : 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.

---

667237-3 : Edge Client logs the routing and IP tables repeatedly

Component: Access Policy Manager

Symptoms:
Edge Client logs the routing and IP tables repeatedly - in each reconnecting attempt.

Conditions:
Edge Client is in reconnecting state and gateway is reachable. However, APM server is not reachable/responding.

Impact:
It fills up the log file with information that is not useful.

Workaround:
There is no workaround at this time.

Fix:
When Edge Client is in re-connection state and the APM server is not reachable/responding, skip logging the Routing/IP tables in each reconnecting attempts.

667138-1 : LTM 12.1.2 HF1 - Upgrade to 12.1.2 HF1 fails with err "folder does not exist"★

Component: TMOS

Symptoms:
After upgrade from 10.2.4 to 12.1.2, full config load fails.

Conditions:
The pre-upgrade version must be 10.2.4 and the pre-upgrade config must have user-defined partitions.

Impact:
After upgrade, if changes are made to the running config (in memory; not on disk), then the config files on disk from upgrade cannot be restored.

Workaround:
10.2.4 config on upgrade is stored at /config/bigpipe/. So, a workaround is to load defaults, then merge the original config using bigpipe.

/usr/libexec/bigpipe merge /config/bigpipe/*.conf

Fix:
Full load after upgrade from 10.2.4 now succeeds.

667028-1 : DNS Express does not run on i11000 platforms with htsplit disabled.

Component: Global Traffic Manager (DNS)

Symptoms:
tmm processes enter a restart loop when trying to run DNS Express (DNSX) on i11000 platforms with htsplit disabled.

Conditions:
-- i11000 platform.
-- htsplit disabled (sys db scheduler.splitplanes.ltm set to false).
-- Trying to run DNSX.

Impact:
tmm processes enter a restart loop. In this condition, DNSX does not run, though other DNS functions are unaffected.

Workaround:
Enable htsplit using the following command:

modify sys db scheduler.splitplanes.ltm value true

Fix:
tmm no longer cores under these conditions. However, you cannot use DNSX with htsplit disabled; htsplit must be enabled.

Note: DNSX works as expected with htsplit enabled, both before and after the fix.

666986-2 : Filter by Support ID is not working in Request Log

Solution Article: K50320144

Component: Application Security Manager

Symptoms:
In some cases the Support ID of a request might be shorter than 19 digits. In this case filter by Support ID does not work in Request Logs.

Conditions:
-- Support ID is shorter than 19 digits.
-- Trying to filter by Support ID.

Impact:
Filter by Support ID is not displayed in filter bar and does not affect the list.

Workaround:
You can try to filter by last 4 digits of Support ID. Although that does not replace filter by Support ID functionality, it might help.

Fix:
Filter by Support ID works for any length but 4 digits (in this case search uses the last 4 digits; also a 4-digit Support ID is not a realistic occurrence).

666790-2 : Use HSB HiGig MAC reset to recover both FCS errors and link instability

Solution Article: K06619044

Component: TMOS

Symptoms:
In addition to HiGig Link instability, FCS errors can be seen on internal switch and HSB Higig link. This is likely some PHY-related issues and can cause instability in communication links.

One symptom associated with this might be that a blade cannot become active and join the cluster.

Conditions:
FCS errors reported in tmm/hsbe2_internal_lbb_hgm. Traffic failure observed on some VIPs or self IPs.

Impact:
Link unstable, frame loss.
TMOS MPI and CDP packet loss and internal blade communication issues.

HSB lockup and accumulated FCS errors observed from stats and log.

Workaround:
A switch port reset might be used to recover this failure. Note, however: that procedure might cause potential HSB lockups.

Fix:
FCS errors and link instability no longer occur.

---

666689-1 : Occasional "profile not found" errors following activate access policy

Component: Access Policy Manager

Symptoms:
Immediately following the applying of a modified access policy it is possible for some profiles to disappear.
It is transient and within a minute or two the profiles are available again.

Conditions:
Clicking "apply access policy" in the GUI or using tmsh to increment snapshot ids will clear the list of profiles and policies and then rebuild those lists. Authentication requests using profiles or policies not yet rebuilt returned the "profile not found" error.

Impact:
Some authentication attempts fail while the lists get rebuilt.
Retrying the authentication a minute or two later succeeds.

Workaround:
Retry the authentication.

Fix:
Applying Access Policies in APM is improved to avoid a short dead time between when the old policies are removed and the new policies are activated.

665778-1 : Non-admin BIG-IP users can now view/re-deploy iApps through TMUI.

Solution Article: K34503519

Component: iApp Technology

Symptoms:
Non-admin BIG-IP users cannot view deployed iApps, so they cannot redeploy the iApp. The system presents an error and does not allow access to the component view or the reconfiguration view. The error shown is 'An error has occurred while trying to process your request.'

Conditions:
-- Login to the BIG-IP system as a non-admin.
-- Try to view components or reconfigure iApps.

Impact:
Cannot view/re-deploy iApps.

Workaround:
Use TMSH to view/re-deploy iApps.

There are two TMUI workarounds to view/re-deploy iApps. Once you employ one of the workarounds, a Manager user can reconfigure the iApp successfully.

Note: After successful submission, the system posts the error described, and the Manager still cannot access the Component list or iApps editing screens.

-- Click on 'app_name' link anywhere in the system where iApp-related objects are listed. For example, if the iApp created a virtual server, click the Application column link on the 'Local Traffic :: Virtual Servers : Virtual Server List' page.

-- Have an Admin user provide the direct link to app. To do so, perform the following procedure:
1. Login as Admin to the BIG-IP system.
2. Navigate to iApps :: Application Services : Applications :: <app_name>.
3. Get the direct link to the app reconfigure page by hovering over the Settings icon and then clicking 'Direct link to this page'. Note: This link will work as long as 'app_name' and template name have not been modified. The URL appears similar to the following:
   https://10.10.10.10/tmui/Control/jspmap/tmui/application/reenter.jsp?mode=app&name=/ptn1/abcd.app/abcd&template_name=/Common/f5.microsoft_exchange_2010_2013_cas.v1.6.1
4. Logout as Admin and login as Manager.
5. Paste the app direct link in the browser's address bar and press Enter.

Fix:
Non-admin BIG-IP users can now view/re-deploy iApps through TMUI.

---

665416-3 : Old versions of APM configuration snapshots need to be reaped more aggressively if not used

Component: Access Policy Manager

Symptoms:
Currently, it takes 24 hrs for old versions of APM config snapshots that are not being used to time out and to release the memory. If access profiles are complex and are updated frequently within 24 hrs, memory resource is likely to be exhausted.

Conditions:
If access profiles are updated frequently within 24 hrs and each version of the configuration snapshot contains many variables.

Impact:
TMM may run out of memory and crash, causing service interruption.

Workaround:
None.

Fix:
Per-session access policy snapshots are now deleted after 60 minutes instead of 24 hours.

---

665354-2 : Silent reboot, identified with bad_tlp_status and completion_time_out in the sel log

Solution Article: K31190471

Component: TMOS

Symptoms:
The most common symptom is a reboot of the unit without much detail in the normal tmm or ltm logs. From there, inspect the SEL logs. In the SEL logs, you will see a message about a bad_tlp_status, followed shortly by a message about completion_time_out_status.

Those two messages together indicate this known issue.

Conditions:
-- There are empty 10 GB ports or 10 GB ports that have optics but are not connected to a proper link.
-- Running on one of the following platforms: i2600, i2800, i4600, i4800.

Impact:
The unit intermittently reboots.

Workaround:
To prevent the issue from occurring, you must populate all 10 Gb ports with optic cables and ensure they are connecting to a working peer link. A single 10 Gb empty or improperly connected port can cause a system reboot.

If that is not possible, however, there is no workaround, and you must contact F5 Technical Support to request a software update or engineering hotfix.

Important: A device Return Materials Authorization (RMA) will not prevent this issue.

Fix:
There is a BIG-IP system software update to disable the 10 Gb FPGA mac receiver until a valid link is detected. This eliminates the issue and prevents the ultra jumbo packet from being sent to the FPGA datapath.

SSL record containing handshake data can exceed maximum fragment size of 16384 bytes because handshake data is not fragmented.

Conditions:
This usually happen when a large certificate or certificate chain is configured for server or client authentication.

Impact:
SSL handshake will fail with client or server that properly checks the record size.

Workaround:
Use a certificate that is smaller in size.

Fix:
Properly fragment handshake data.

664507-3 : When BIG-IP is used as SP with IdP-connector automation, updates to remotely published metadata may remove certificate reference from the local configuration

Component: Access Policy Manager

Symptoms:
IdP-connector automation removes certificate reference when update to metadata file is detected, and metadata file contains multiple signing certificates

Conditions:
- BIG-IP is used as SAML SP with configured IdP-connector automation via remotely published metadata.
- Remotely published SAML metadata contains multiple signing certificates.
- Remotely published SAML metadata is periodically updated.

Impact:
Certificate reference to remotely published metadata is removed from local configuration (saml-idp-connector object). As a result, assertions generated by external IdP will not be accepted until proper certificate is configured on saml-idp-connector object again.

Workaround:
When remote metadata is changed, manually update certificate reference on saml-idp-connector object.

Fix:
When changes to remotely published SAML metadata are detected by IdP-connector automation, certificate is no longer removed from saml-idp-connector object.

664057-2 : Upgrading GTM from pre-12.0.0 to post 12.0.0 no longer removes WideIPs without pools attached if they have an iRule attached

Component: TMOS

Symptoms:
Upgrades from pre-12.0.0 to 12.0.0 or beyond would delete WideIPs without pools attached even if they had an iRule attached.

Conditions:
Pre-12.0.0 configuration with an WideIP without any pools, but with an iRule.

Impact:
Some or all of a post-upgrade "GSLB-typed" wideip would be lost during the upgrade process.

Workaround:
Manually add missing WideIPs after upgrade.

Fix:
Fixed issue that could delete certain types of GTM WideIPs after an upgrade from a pre-12.0.0 version to a post 12.0.0 version.

664017-3 : OCSP may reject valid responses

Component: TMOS

Symptoms:
If OCSP is configured with certain responders, a valid response may be rejected with the following error:

OCSP response: got EOF

Conditions:
This is entirely dependent on the behavior of the server. If a responder sends null or blank data (but does not close the connection) OCSP simply ends the response.

Impact:
Valid OCSP responses may be rejected.

Workaround:
None.

Fix:
These responses are now accepted.

Solution Article: K31981624

Component: TMOS

Symptoms:
The alertd daemon does not run logrotate when the diskmonitor utility detects that /var/log has less than 10% free space.

Conditions:
/var/log has less than 10% free space.

Impact:
The /var/log filesystem might become completely full, preventing new log messages from being written.

Note: K8865: Overview of the diskmonitor utility (https://support.f5.com/csp/article/K8865) provides a desription for expected behavior.

Workaround:
None.

Fix:
The alertd daemon now correctly recognizes the log message from diskmonitor to initiate logrotate.

663551-1 : SERVERSSL_DATA is not triggered when iRule issues [SSL::collect] in the SERVERSSL_HANDSHAKE event

Solution Article: K14942957

Component: Local Traffic Manager

Symptoms:
If an iRule calls [SSL::collect] in the SERVERSSL_HANDSHAKE event, the expected result is that the SERVERSSL_DATA event will be raised when the serverside receives the SSL data. Then, the decrypted SSL data can be examined and manipulated.
*****************************
when SERVERSSL_HANDSHAKE {
    SSL::collect
}
when SERVERSSL_DATA {
    log local0. "ServerSSL Data"
    log local0. [SSL::payload]
    SSL::release
}
*****************************

The issue is that SERVERSSL_DATA is not raised, even when the serverside receives the SSL data when the iRule calls the [SSL::collect] in the SERVERSSL_HANDSHAKE:
****************************
when SERVERSSL_HANDSHAKE {
    SSL::collect
}
****************************

Conditions:
Calling the [SSL::collect] in the SERVERSSL_HANDSHAKE event.
****************************
when SERVERSSL_HANDSHAKE {
    SSL::collect
}
****************************

Impact:
SERVERSSL_DATA event is not raised.

Workaround:
Add the [SSL::release] command in the SERVERSSL_HANDSHAKE event.
**********************************
when SERVERSSL_HANDSHAKE {
    SSL::collect
    SSL::release
}

Fix:
SERVERSSL_DATA event is now raised when an iRule calls [SSL::collect] in the SERVERSSL_HANDSHAKE.

663535-1 : Sending ASM cookies with "secure" attribute even without client-ssl profile

Component: Application Security Manager

Symptoms:
ASM cookies can be set with "secure" attribute on when BIG-IP works on SSL profile.

Conditions:
Enabling ASM, network to BIG-IP without client-ssl.

Impact:
When working with encrypted network in the client side but clear network in the ASM virtual, cookies cannot be set with "secure" attributes.

Workaround:
There is no workaround at this time.

Fix:
Added an internal parameter "assume_https", to decide always setting the "secure" attribute, even when the BIG-IP network is clear.

---

663521-2 : Intermittent dropping of multicast packets on certain BIG-IP platforms

Component: TMOS

Symptoms:
The switch device on the VIPRION B2250 and B4300 blades and the BIG-IP 10x00, i10x00, i7x00 and i5x00 platforms might drop multicast packets under certain high traffic conditions.

Conditions:
-- Certain high-traffic conditions.
-- Running on the specified blades/platforms.

Note: These dropped packets are counted under the 'drop_out' column from 'show net interface all-properties'.

Impact:
Dropped multicast packets, possibly impacting multicast protocols.

Workaround:
None.

Behavior Change:
Under certain high traffic conditions, multicast and broadcast packets will no longer be dropped.

663506-7 : apmd crash during ldap cache initialization

Solution Article: K30533350

Component: Access Policy Manager

Symptoms:
apmd crashes.

Conditions:
- LDAP module is in use in an access policy,
- APM end-users are logging in, while administrator modifies AAA LDAP Server or LDAP Agent,
- Cache update takes a while (too many groups in domain and/or slow network).

Impact:
BIG-IP cannot process user logon request, until apmd is restarted and LDAP cache is updated

Workaround:
The best practice is to update policy/AAA LDAP Server when BIG-IP is not under load. Then make one logon manually. apmd updates caches on first APM end-user's logon. Once caches update, all the further logons should happen much faster and should not cause any problems

Fix:
APMD now handles the generation of LDAP Query / AD Query nested group cache correctly during high authentication load.

663366-3 : SEGV fault can occur during tmm 'panic' on i4x00 and i2x00 platforms.

Component: TMOS

Symptoms:
On the i4x00 and i2x00 platforms, TMM can encounter a second SEGV fault while crashing from an initial 'panic'.

Conditions:
-- i4x00 and i2x00 platforms.
-- TMM encounters a second SEGV fault while crashing from an initial 'panic'.

Impact:
TMM is crashing due to a 'panic'. No additional impact, as traffic is already disrupted while tmm restarts.

Workaround:
None.

Fix:
This release fixes the driver shutdown code to prevent SEGV during TMM panic.

---

663333-1 : TMM may core in PBA mode id LSN pool is under provisioned or the utilization is high

Component: Carrier-Grade NAT

Symptoms:
TMM may core while trying to allocate a new block

Conditions:
If LSN pool is under provisioned OR if the utilization is high, TMM may need to send MPI messages to other TMMs to search for other blocks. The TMM may core if these operations time out

Impact:
Traffic disrupted while tmm restarts.

---

663326-2 : Thales HSM: "fipskey.nethsm --export" fails to make stub keys

Component: Local Traffic Manager

Symptoms:
When using "fipskey.nethsm --export -i /shared/tmp/testkey.pem -o thaleskey" to export a key file from BIG-IP and import into HSM, the HSM fails to generate the stub key at /config/ssl/ssl.key/ on the BIG-IP system.

Conditions:
-- Thales HSM is installed.
-- Running 'fipskey.nethsm --export' to export a key file from BIG-IP and import it to the Thales HSM.

Impact:
Even the key has been stored in HSM, the BIG-IP is still unable to use it because of its lacking stub key to be configured on the BIG-IP system.

Workaround:
This can be worked around by directly using the Thales command, for example:

[root@localhost:Active:Standalone] config # generatekey --import pkcs11 certreq=yes
type: Key type? (DES3, RSA, DES2) [RSA] >
pemreadfile: PEM file containing RSA key? []
> /shared/tmp/testkey.pem
embedsavefile: Filename to write key to? []
> /config/ssl/ssl.key/thales2
plainname: Key name? [] > thales2
x509country: Country code? [] > US
x509province: State or province? [] > WA
x509locality: City or locality? [] >
x509org: Organisation? [] > F5
x509orgunit: Organisation unit? [] > AS
x509dnscommon: Domain name? [] >
x509email: Email address? [] > test@test.com
nvram: Blob in NVRAM (needs ACS)? (yes/no) [no] >
digest: Digest to sign cert req with? (md5, sha1, sha256, sha384, sha512)
  [default sha1] >

Fix:
When using 'fipskey.nethsm --export -i /shared/tmp/testkey.pem -o thaleskey' to export a key file from BIG-IP and import into HSM, the HSM now generates a stub key and stores it at /config/ssl/ssl.key/ on the BIG-IP system, as expected.

663310-3 : named reports "file format mismatch" when upgrading to versions with Bind 9.9.X versions for text slave zone files★

Solution Article: K50871313

Component: Global Traffic Manager (DNS)

Symptoms:
named reports "file format mismatch", zone files are renamed randomly to db-XXXX files, and zone cannot be loaded.

Conditions:
-- Upgrade from BIG-IP containing pre-9.9.X versions of Bind, to BIG-IP versions with Bind versions later than 9.9.x.
-- Slave zone files are in text format.
-- No options set for masterfile-format text.

Impact:
Zones cannot be loaded.

Workaround:
Before upgrading, add the following line to the named.conf options:
masterfile-format text;

Fix:
BIND 9.9.x changes the default behavior governing the storage format of slave zone files to "raw" from "text".

On upgrade, the config needs to be parsed looking for slave zones that do not specify the masterfile-format and set them to "text".

663127-1 : Empty attribute values in SAML Identity Provider configuration may cause error when loading configuration.

Component: Access Policy Manager

Symptoms:
Symptom will show as an error log in /var/log/apm similar to the one below:

Internal error processing sso config /Common/idp_obj_name
sso_tmconf_string_parse_list

When this error message is logged, subsequent authentication attempt using this BIG-IP as IdP object will fail.

Conditions:
SAML Identity Provider configuration is invalid: attribute contains empty value(s), for example:

apm sso saml /Common/idp_obj {
    attributes {
        {
            multi-values { "" user@f5.com }
            name User.Email
        }
    }

Impact:
Authentication will fail for users using affected SAML IdP object.

Workaround:
Manually edit bigip.conf configuration fail and remove empty value(s) in SAML attribute, e.g.:

apm sso saml /Common/idp_obj {
    attributes {
        {
            multi-values { user@f5.com }
            name User.Email
        }
    }

Fix:
Empty values in SAML attributes will no longer be accepted by validation logic.

663073-1 : GSLB Pool member Manage page combo box has an issue that can cause the wrong pool member to be removed from the available list when adding a member to the selected list.

Component: Global Traffic Manager (DNS)

Symptoms:
GSLB Pool member Manage page combo box has an issue that can cause the wrong pool member to be removed from the available list when adding a member to the selected list.

Conditions:
When adding a pool member via the combo box, if you click the arrow to expand the dropdown list and select a member by clicking on it, that member name is added to the text box.

If you then mouse over other members in the dropdown list, and then click the Add button, the system adds the selected member to the list, but also removes the wrong member from the combo box: more specifically, it removes the member that was last highlighted by the mouse over.

Impact:
Available pool members might be potentially lost from the combo box until a page reload.

Note: The pool members are not gone from the system; they are still present, just not displayed.

Workaround:
Either use TMSH or place the mouse cursor away from the combo box, and use the text box to narrow down the content in the dropdown list. Then use the arrow keys and the Enter key to select the desired pool member.

Fix:
Changed the behavior of the combo box when a member is selected by clicking on it in the dropdown list. Adding a selected pool member as described above will cause the combo box to correctly remove that pool member from the combo box.

663063-2 : Disabling pool member used in busy HSL TCP destination can result service disruption.

Component: TMOS

Symptoms:
Manually disabling an otherwise available pool member from a pool used as HSL TCP destination can result in tmm crash and service disruption.

This is more likely to occur when HSL destination is using 'balanced' distribution.

Conditions:
-- Busy HSL destination configured with TCP protocol, balanced distribution, and using pool.
-- Manually disabling a pool member.

Impact:
Service disruption while tmm recovers. HA fail-over event. Traffic disrupted while tmm restarts.

Workaround:
You can avoid the issue in either of these ways:
-- Do not manually disable busy pool members that can still respond to TCP handshake.
-- Disable the service on the pool member first.

Fix:
TMM crash no longer occurs when HSL TCP pool member with pending connection is manually disabled.

662911-2 : SASP monitor uses same UID for all vCMP guests in a chassis or appliance

Solution Article: K93119070

Component: Local Traffic Manager

Symptoms:
The SASP GWM monitor generates the LB UID from the chassis serial number of the platform on which BIG-IP is running. All vCMP guests running on the platform attempt to use the same UID.

The LB UID used to connect to the Server/Application State Protocol (SASP) Group Workload Manager (GWM) is required to be unique for each client connecting to the GWM.

As a result, only one vCMP guest running on each BIG-IP appliance or VIPRION chassis is able to successfully use the SASP monitor.
- The SASP monitor running on the first vCMP guest can successfully connect to the SASP GWM.
- Subsequent SASP monitor instances running on other vCMP guests will fail to connect to the SASP GWM.

Conditions:
This occurs when multiple vCMP guests are running on a single BIG-IP appliance or VIPRION chassis, each using a SASP monitor connecting to the same SASP GWM to monitor pool member availability.

Impact:
The SASP monitor is unable to monitor pool member availability on more than one vCMP guest running on a single BIG-IP appliance or VIPRION chassis.

Workaround:
None.

Fix:
The SASP monitor can be used to monitor pool member availability on multiple vCMP guests running on a single BIG-IP appliance or VIPRION chassis.

662844 : TMM crashes if Diameter MRF mirroring is enabled in v12.x.x. Diameter MRF mirroring is not implemented in v12.x.x.

Solution Article: K87735013

Component: Service Provider

Symptoms:
Mirroring for Diameter MRF was not implemented in v12.x.x. However, there is a option that allows the user to enable it. When enabled, tmm crashes.

Conditions:
-- Connection mirroring is enabled for Diameter MRF virtual server's router profile.
-- Using v12.x.x.

Impact:
TMM crashes. Traffic disrupted while tmm restarts.

Note: Mirroring for Diameter MRF was implemented in v13.0.0. The presence of the option to enable the unimplemented functionality is erroneous.

Workaround:
Do not enable Diameter MRF router profile's connection mirroring setting for v12.x.x.

Fix:
Diameter MRF mirroring for Diameter MR has been implemented beginning with v13.0.0. Enabling this option in v12.x.x results in a tmm crash.

     2. Under 'JavaPatcher Settings' select 'Signer' and 'Signer Key' to the one created above (e.g., 'fips1.crt' and 'fips1.key', respectively).
   + Create an access profile.
   + Create a virtual server and attach the access profile and rewrite profile to it.
     (Note: You must also include other dependent settings, such as a connectivity profile.)
3. Start a policy sync from the device.

Impact:
Feature failure for specific configurations.

Workaround:
None.

Fix:
Now APM policy sync succeeds even when policy includes FIPS key.

662364-2 : MRF DIAMETER: IP ToS not passing through with DIAMETER

Component: Service Provider

Symptoms:
IP layer's ToS is not passing through MRF Diameter.

Conditions:
-- The IP ToS bit is received in the clientside connection.
-- ip-tos-to-client is set as pass-through.

Impact:
The ToS from the client does not reach the server.

Workaround:
Use an iRule to preserve the ToS from the client and set it to serverside's connection.

Fix:
The ToS bit that arrives from the clientside connection is able to pass-through with Diameter MRF.

662331-1 : 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.

Component: Local Traffic Manager

Symptoms:
Using Node.js package manager (NPM) to install a large Node.js package in the TMUI results in truncated contents in the workspace.

Conditions:
Installing large Node.js packages using the TMUI.

Impact:
The workspace contents will be truncated. Some of the package contents will be missing, or boilerplate F5 elements (f5-nodejs, package.json, etc.) will not be shown.

Workaround:
None.

Note: TMSH recognizes the entire file structure of node_modules (e.g., package.json and module folders of f5-nodejs and async), but TMUI does not.

Fix:
All contents from the workspace filesystem are now shown and are editable from the TMUI.

Conditions:
iRules that contain calls to ASN1::decode with "a" or "B" characters in the format string.

Impact:
Memory leak, degraded performance, potential eventual out-of-memory crash.

Workaround:
None.

Note: Because of the memory leak associated with this issue, using calls to ASN1::decode with "a" or "B" characters in the format string should be avoided.

Fix:
Prevented memory leak when using calls to ASN1::decode with "a" or "B" characters in the format string.

-- The chassis is loaded with many blades.
-- The high availability (HA) configuration is intra-chassis.
-- RADIUS subscriber is added with custom attributes.
-- The subscriber attributes are corrupted or erased.

Impact:
TMM crashes. The slot reboots, potentially triggering further daglib hash changes. May result in cascading core under load. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
Verify the validity of the AVPs before copying the attributes

660170-1 : tmm may crash at ~75% of VLAN failsafe timeout expiration

Solution Article: K28505910

Component: Local Traffic Manager

Symptoms:
When VLAN failsafe is configured, and the VLAN failsafe timeout is 3/4 expired, tmm wants to generate ICMP traffic to evoke a network response. When this occurs, the system might experience a crash.

Conditions:
- VLAN failsafe is configured on a VLAN, for example with the recommended VLAN failsafe timeout of 90 sec.
- The VLAN does not observe ARP/ndp traffic for 3/4 of the timeout, 67.5 seconds.
- ICMP traffic generated to provoke a network response can under certain circumstances cause a TMM crash.

Impact:
TMM crashes, failover is triggered, as it would with a fully expired VLAN-failsafe-timeout condition (note that failover with a fully expired VLAN failsafe is correct behavior).

Traffic on other VLANs might be disrupted while TMM restarts. (Traffic on the VLAN-failsafe-triggered VLAN is already disrupted, causing the timeout to expire.)

Workaround:
1. To allow for VLAN failsafe to be updated for any frame, run the following command with VLAN failsafe enabled, run the following command:
 tmsh modify failover.vlanfailsafe.resettimeronanyframe enable

This configuration increases the confidence that in the case of a timeout expiry a real traffic disruption is detected.

2. Set the timeout of VLAN failsafe to 4/3 of the setting you want, for example, to have a timeout setting of 90, specify 120. With this setting, failover occurs at 90 seconds for a fully quiescent network.

Note: Having a fully quiescent network is a rare occurrence and likely indicates that another issue is occurring anyway.

Fix:
Generating ICMP traffic from TMM is no longer exposed to a potential crash in an invalid configuration or a completely quiet network, when generating ICMP traffic to provoke a network response on an expiring timer of VLAN failsafe, assuming the following configuration:

- VLAN failsafe is configured.
- VLAN failsafe expired 3/4 of the configured timeout (e.g., 67.5 seconds of 90 seconds ).

659912-1 : GSLB Pool Member Manage page display issues and error message

Component: Global Traffic Manager (DNS)

Symptoms:
The GSLB Pool Member Manage page displays an error message 'Entry could not be matched against existing objects' when using the static-target checkbox to add a member that does not exist on the BIG-IP config.

Also when editing a pool member, the pool member's name will not be auto-selected in the combo box.

Conditions:
-- GSLB pool configured.
-- Members available for addition to the pool.

Note: This issue can happen when creating a pool in the members section as well as on the pool members manage page.

Impact:
Degraded usability.

Workaround:
Use TMSH to add a static-target and to edit pool members.

Fix:
Fixed issue with the edit button and issue that prevented adding as a static-target a GSLB pool member that was not part of the GTM config. Now, if static target is enabled, you can type the name of the target without the target being configured on the system.

659899-1 : Rare, intermittent system instability observed in dynamic load-balancing modes

Solution Article: K10589537

Component: Local Traffic Manager

Symptoms:
The dynamic pool member load-balancing modes require a precision measurement of active connection counts and/or rates. Rare, intermittent system instability has been observed in dynamic pool member selection when a new connection arrives. TMM may restart, leaving a core file.

Conditions:
LTM pool configured to use a dynamic load-balancing mode ('ltm pool NAME load-balancing-mode MODE' where MODE is one of the dynamic load-balancing modes, such as dynamic-ratio-member, least-connections-node, predictive-node, etc.). The dynamic modes use the session database to share data among all TMM instances, and under extremely rare conditions, the session database may become unreliable.

Impact:
TMM restarts and leaves a core file. Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
The dynamic load-balancing modes are now more tolerant of errors from the underlying session database.

659648-2 : LTM Policy rule name migration doesn't properly handle whitespace

Component: Local Traffic Manager

Symptoms:
LTM Policy validation does not allow rule names to begin or end with whitespace characters. When migrating configuration to the next version, the migration process attempts to trim off any leading and trailing whitespace. However, this process does not handle leading and trailing whitespace when such characters occur within a double quoted string.

Conditions:
LTM policy with a rule name that contains leading and/or trailing whitespace characters. These will typically occur within a double-quoted string. Here is an example that one might find in bigip.conf:

ltm policy example1 {
    rules {
        " leading and trailing spaces " {
            ...
        }
        ...
    }

Impact:
Policy rules are migrated incorrectly, then fail validation because there of remaining leading and/or trailing whitespace characters.

Workaround:
Prior to migration, LTM Policy rule name can be renamed to remove leading and trailing whitespace. After a failed migration, bigip.conf can be manually edited to remove offending characters and then the configuration can be manually loaded.

Fix:
LTM Policy migration properly handles whitespace in rule names in a quoted string.

659567-1 : iRule command PEM::session functions differently in 12.1.x and 13.0.0 than it did in prior versions

Solution Article: K94685557

Component: Policy Enforcement Manager

Symptoms:
When the RADIUS discovery virtual server and the traffic listener virtual server sit in two different route domains, the iRule command 'PEM::session info $sub subscriber-id' may not be able to fetch the subscriber-id.

Conditions:
-- Running v12.1.x or v13.0.0.
-- RADIUS server.
-- Use of iRule command PEM::session.

Impact:
'PEM::session info state/subscriber-id' commands might not return the expected session info.

Workaround:
None.

Fix:
iRule command PEM::session functions differently in 12.1.x and 13.0.0 than it did in prior versions. The commands now consider route domains.

659371-2 : apmd crashes executing iRule policy evaluate

Component: Access Policy Manager

Symptoms:
Following a restart, if apmd executes an iRule policy evaluate before its reinitialization is complete, apmd can crash.

Conditions:
If apmd restarts due to a crash or explicit restart command but tmm remains active, then iRule policy evaluate commands can reach apmd before it completes initialization and it will crash.

Impact:
apmd crashes and restarts, preventing end users from logging in.

Workaround:
NOne.

Fix:
Now APMD has a more robust initialization process to ensure that it does not execute access policies from iRule commands before it is ready.

---

659057-1 : BIG-IP iSeries: Retrieving the gateway from the Host via REST through the LCD

Component: TMOS

Symptoms:
The LCD on BIG-IP iSeries appliances must detect whether the system is in IPv4 or IPv6 context before retrieving the gateway from the Host via REST. If two gateways are configured (IPv4 and IPv6) only whichever is first in the list is returned via REST and will be set on the Host.

Conditions:
If two gateways are configured (IPv4 and IPv6).

Impact:
Incorrect gateway retrieval can create bad configs which would impact traffic resulting in failed ping attempts, destination unreachable errors, request timeouts, etc.

Workaround:
No workaround at this time.

Fix:
LCD code now retrieves the correct gateway when switching between IPV4 and IPV6 context.

658989-2 : Memory leak when connection terminates in iRule process

Component: Local Traffic Manager

Symptoms:
Memory leak eventually leading to alloc failure and TMM crash.

Conditions:
Connection is aborted/terminated when iRule processing is suspended for the current connection.

Impact:
Memory leak and eventual TMM restart. Traffic disrupted while tmm restarts.

Workaround:
Avoid suspend/park commands in iRule processing.

Fix:
Memory no longer leaks when connection is aborted/terminated when iRule processing is suspended.

---

658852-5 : Empty User-Agent in iSessions requests from APM client on Windows

Component: Access Policy Manager

Symptoms:
'User-Agent' might be empty in some '/isession' requests from APM client on Microsoft Windows. Having empty User-Agent headers is not in RFC compliance and forces some firewall to block the connection. This might result in failure to establish a VPN tunnel.

Conditions:
'/isession' requests from APM client on Windows.

Impact:
Failure to establish a VPN tunnel.

Workaround:
None.

Fix:
Now all connections from Windows APM VPN client contain 'User-Agent' headers, as expected.

658636-2 : When creating LTM or DNS monitors through batch/transaction mode newlines are improperly escaped.

Solution Article: K51355172

Component: TMOS

Symptoms:
- LTM/DNS monitors created via tmsh batch/transactions improperly escape newline characters.
- Expected escaping: \r\n
- Actual escaping: \\r\\n
- Impact: The URI sent is not correct,

Conditions:
When creating LTM or DNS monitors through batch/transaction mode when strings contain newline characters. For example, using the following commands to batch-create:

create gtm monitor http one_test_mon { send "GET / HTTP/1.0\r\nHost: abc.example.com\r\nUser-Agent: slb-healthcheck\r\nConnection: Close\r\n\r\n" recv "200"}
submit cli transaction
list gtm monitor http one_test_mon

The system creates the following monitor:

gtm monitor http one_test_mon {
    defaults-from http
    destination *:*
    interval 30
    probe-timeout 5
    recv 200
    send "GET / HTTP/1.0\\r\\nHost: abc.example.com\\r\\nUser-Agent: slb-healthcheck\\r\\nConnection: Close\\r\\n\\r\\n"

Impact:
Cannot use batch/transaction mode in TMSH to create LTM or DNS monitors. Cannot use LTM or DNS monitors created using batch/transaction mode in tmsh.

Workaround:
Create the monitor directly in tmsh without using batch/transaction mode.

Fix:
When creating LTM or DNS monitors through batch/transaction mode newlines are now properly escaped.

658574-2 : An accelerated flow transmits packets to a stale (incorrect) destination MAC address.

Solution Article: K61847644

Component: TMOS

Symptoms:
An accelerated flow can send to a stale destination MAC address after the ARP packet with the updated MAC address is received.

Warning: disabling auto-lasthop is not enough when they want BIG-IP to use updated destination MAC address.

Conditions:
A flow is accelerated with a destination MAC address that changes while the flow is accelerated.

Impact:
The BIG-IP system sends packets to a stale (incorrect) destination MAC address. In this case, the new MAC address is not updated for the accelerated flow and the flow will continue to send traffic using the original MAC address.

Workaround:
Disable HW acceleration. Prevent the downstream destination MAC address from changing. For example, if the downstream unit is a BIG-IP active/standby configuration, then use MAC masquerading to prevent the MAC address from changing.

658343-2 : AVR tcp-analytics: per-host RTT average may show incorrect values

Solution Article: K33043439

Component: Application Visibility and Reporting

Symptoms:
When viewing the Statistics :: Analytics :: TCP :: RTT, then selecting (in the table below the graph), View By: "Remote Host IP Address", the values presented RTT Avg (ms) may be incorrect (they could even be larger than the RTT Max column).

As values are aggregated through the data tables, the reported rtt average value becomes larger and larger.

Conditions:
AVR is provisioned, and a tcp-analytics profile is attached to a virtual server.

Impact:
The values reported in the RTT Avg column when viewing by Remote Host IP Address may be incorrect.

Workaround:
None.

Fix:
The rtt_count, rtt_max, rtt_avg, rtt_sum metrics after day aggregation and week aggregations are now correct in the day, week, month reports. The rtt_sum is now aggregated with correct value (exceed max int), as expected.

658321-2 : Websafe features might break in IE8

Component: Fraud Protection Services

Symptoms:
IE8 transform all custom HTTP headers names to lowercase
in case header name configured with upper-case characters, WebSafe feature might break.

Conditions:
custom HTTP header configured with upper case characters
client is IE8.

Impact:
FPS plugin will not find the header, as it received lower-case but configured with upper-case characters
as a result, WebSafe functionality is broken (functionality which involve the custom HTTP header, e.g. ajax username header)

Workaround:
Set custom HTTP header name to lower case only.

Fix:
FPS now performs case-insensitive matches for custom HTTP headers.

658261-2 : TMM core after HA during GY reporting

Component: Policy Enforcement Manager

Symptoms:
If intra-chassis failover is triggered in a loaded chassis, the tmm crashes in some cases of GY reporting

Conditions:
-- Failover is triggered,
-- The daglib hash redistributes the subscriber DATA to different slots.
-- Existing flows continue on the slots that were allocated using the old hash of daglib.

Note: This is a rarely encountered issue that occurred in a setup with 8 slots and 750 thousand subscribers.

Impact:
Slot reboots. May trigger more hash rearrangement. Traffic disrupted while tmm restarts.

Workaround:
None.

658214-2 : TCP connection fail intermittently for mirrored fastl4 virtual server

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.

Impact:
FastL4 mirroring does not always forward SYN to server after receiving context ACK. Connections fail.

Workaround:
Set the tm.fastl4_ack_mirror dv variable using the following command: tmsh modify sys db tm.fastl4_ack_mirror value disable.

Fix:
In this release, mirrored FastL4 virtual server now forward the SYN on the server-side after receiving the context-ack from the peer as expected.

Solution Article: K23150504

Component: Policy Enforcement Manager

Symptoms:
If intra-chassis failover is triggered in a loaded chassis, the tmm crashes in some cases of subscriber creation.

Conditions:
-- The chassis is loaded with many blades.
-- The HA configuration is intra-chassis.
-- RADIUS subscriber is added with custom attributes.
-- The subscriber attributes are corrupted or erased.

Impact:
TMM crashes. The slot reboots, potentially triggering further daglib hash changes. May result in cascading core under load. Traffic disrupted while tmm restarts.

657795-1 : Possible performance impact on some SSL connections

Solution Article: K51498984

Component: Local Traffic Manager

Symptoms:
Some SSL connections may be delayed by almost exactly 5 seconds. The delay occurs between the SSL client hello and the server hello response from the BIG-IP system.

Conditions:
-- SSL configured on a Virtual Server. Affects VIPRION/vCMP Guests.

-- Client connects with an SSL session ID that is not in the cache, and in a very specific format that causes tmm to associate the session ID to a blade that does not exist.

Impact:
Performance may be impacted on those SSL connections.

Workaround:
Disable SSL session cache by setting cache-size to zero in the clientssl profile.

Fix:
This release fixes an issue that might cause performance impact on certain SSL connections.

657713-5 : Gateway pool action may trigger the Traffic Management Microkernel (TMM) to produce a core file and restart.

Solution Article: K05052273

Component: Local Traffic Manager

Symptoms:
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.
-- Your BIG-IP system logs a SIGFPE to the /var/log/tmm file at the same time TMM produces a core file and restarts.
-- In one of the /var/log/tmm log files, you may observe error messages similar to the following example:

notice panic: ../modules/hudfilter/hudfilter.c:1063: Assertion "valid node" failed.
notice ** SIGFPE **

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

-- Your BIG-IP system is configured to route traffic using a gateway pool.
-- The gateway pool is configured with Action On Service Down = Reject.
-- The pool monitor marks all members of the gateway pool as unavailable.
-- A connection is rejected by the gateway pool.

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:
Set service-down-action to none or reselect.

Fix:
Gateway pool action no longer triggers TMM to produce a core file and restart.

657632-4 : Rarely if a subscriber delete is performed following HA switchover, tmm may crash

Component: Policy Enforcement Manager

Symptoms:
If a subscriber delete is performed following a HA switchover, tmm may coredump. The probability of this scenario is rare, where a subscriber may have been freed during switchover and a subsequent forced delete command quickly follows.

Conditions:
-- A subscriber delete command followed by a HA switchover.
-- During the switchover, the subscriber was freed.

Impact:
Traffic disrupted while tmm restarts.

Workaround:
None.

Fix:
The system now removes the subscriber index from the table if present in these cases.

Symptoms:
Migrating the configuration from a B2100 blade to a newer variant, as documented in the "Migrating the Configuration on B2000 Series Blades" page in the "VIPRION Systems: Blade Migration" manual, may show output indicating a failure.

Conditions:
All such blade upgrades.

Impact:
The line 'load ucs failed!' should be ignored. If the line '/var/local/ucs/upgradeConfig-your-serial-number.ucs is loaded.' is present, then the UCS load was in fact successful and you can proceed with the instructions.

Workaround:
The line 'load ucs failed!' should be ignored. If the line '/var/local/ucs/upgradeConfig-your-serial-number.ucs is loaded.' is present, then the UCS load was in fact successful and you can proceed with the instructions.

655807-5 : With QoS LB, packet rate score is calculated incorrectly and dominates the QoS score

Solution Article: K40341291

Component: Global Traffic Manager (DNS)

Symptoms:
When choosing QoS Load balance, packet rate is dominating the score.

Conditions:
QoS load balance.

Impact:
Load balance decision is mostly impacted by packet rate.

---

655793-1 : SSL persistence parsing issues due to SSL / TCP boundary mismatch

Solution Article: K04178391

Component: Local Traffic Manager

Symptoms:
When the SSL client or server system is set up to send SSL messages whose boundaries do not align with underlying TCP boundaries, the parser fails when SSL persistence is enabled.

So, any SSL record spanning over multiple TCP segments (in this case it's ServerHello, Certificate, and ServerHelloDone) triggers the issue with the SSID error RST cause.

This can also result from a message size exceeding the maximum configured size (default is 32K).

Conditions:
[1] SSL persistence is enabled.
[2a] SSL message boundary does not align with underlying TCP segment boundary. One example of boundary mismatch is when the TCP MTU size is changed to a lower value (around 1200 bytes). Even then there may be specific values for which the boundaries match and parsing succeeds.
[2b] The message size is greater than the maximum configured size (default 32k).

Impact:
When the parsing fails, the SSL client or server hangs and times out. In other words, SSL traffic is affected.

The SSL parsing should succeed regardless of a match or mismatch between SSL message boundary and TCP segment boundary.

Workaround:
Disable SSL persistence.

Fix:
The system now switches the state of the SSL persistence to pass through all remaining messages, since no further parsing is needed.

---

655671-1 : Polling time waiting for I2C bus transactions in the bcm56xxd daemon needs to be reduced

Component: TMOS

Symptoms:
On platforms that run the bcm56xxd daemon, the polling time that the system waits for I2C bus transactions to complete runs too long. On systems with I2C bus issues, this can lead to bcm56xxd core files, because the bcm56xxd daemon doesn't reset the watchdog so the watchdog timer kills the process.

Conditions:
This is an issue only when there is a stuck I2C bus, which occurs rarely.

Impact:
bcm56xxd process may core and restart. That typically resets the I2C bus, which resolves any issues.

Workaround:
None. Typically, the issue resolves itself.

Fix:
The number of times the bcm56xxd process polls for an I2C bus transaction to complete is reduced to prevent bcm56xxd core files.

655649-2 : 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':

               [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.

655628-1 : TCP analytics does not release resources under specific sequence of packets

Component: Local Traffic Manager

Symptoms:
TCP analytics does not release memory when a specific sequence of packets is observed, and memory usage increases as more such flows occur.

Conditions:
-- A TCP analytics profile is configured to collect clientside/serverside analytics data.
-- AVR is provisioned.
-- FastL4 and HTTP profiles are configured.
-- A specific sequence of packets (on the serverside) occurs.

Impact:
Main memory occupied by TCP analytics is not released which might lead to memory exhaustion on the BIG-IP system.

Workaround:
Turn off collecting TCP analytics data for the virtual server.

Fix:
TCP analytics now releases resources properly.

---

655500 : Rekey SSH sessions after one hour

Component: TMOS

Symptoms:
Common Criteria requires that SSH session be rekeyed at least every hour

Conditions:
SSH connections to or from the BIG-IP system.

Impact:
SSH sessions are rekeyed in response to the quantity of data transferred, or on user demand, but not on the basis of elapsed time

Workaround:
If time-based rekeying is required in your environment, edit the SSH configuration to include a RekeyLimit with both data and time parameters using a command similar to the following:
tmsh modify sys sshd include 'RekeyLimit 256M 3600s'

Outbound SSH client connections can be modified by adding the same RekeyLimit configuration to /config/ssh/ssh_config or by including that option on the command line when calling the ssh client.

Fix:
SSH sessions are now rekeyed every hour regardless of the quantity of data transferred.

655470 : IP Intelligence logging publisher removal can cause tmm crash

Solution Article: K79924625

Component: Advanced Firewall Manager

Symptoms:
TMM restart immediately after removing global ip-intelligence logging publisher.

Conditions:
1) Global IP Intelligence logging enabled.
2) While new incoming connections are handled by the system, delete the global logging publisher using the following command:
modify security log profile global-network ip-intelligence { log-publisher none }

Impact:
Traffic disrupted while tmm restarts. This is an intermittent, timing-related issue.

Note: Because deleting the global ip-intelligence logging configuration publisher is uncommon, and might occur once, at setup, this issue is unlikely to manifest.

Workaround:
There is no workaround, other than to not delete the ip-intelligence global logging publisher when heavy traffic is being handled.

Fix:
Error handling now checks for NULL publisher and prevents the TMM restart.

---

655445-2 : Provide the ability to globally specifiy a DSCP value.

Component: Global Traffic Manager (DNS)

Symptoms:
The DSCP value is not configurable for some types of traffic, which can lead to dropped traffic during adverse network conditions.

Conditions:
Under adverse network conditions, monitor traffic can be dropped by the network.

Impact:
BIG-IP DNS incorrectly reports resources as unavailable because monitor traffic is dropped by the network due to congestion with unrelated traffic.

Workaround:
None.

Fix:
Setting the new db variable tm.egressdscp to a value other than the default value of 0, results in the system setting the DSCP value for outgoing traffic to the configured value.

655357-2 : Corrupted L2 FDB entries on B4450 blades might result in dropped traffic

Solution Article: K06245820

Component: TMOS

Symptoms:
ARP replies reach front panel port of B4450 blades but fail to reach TMMs.

This occurs because the switch in the B4450 blade has an L2 learning issue in the switch fabric that requires the system to correct the new L2 FDB entries learned on Higig trunks. The L2 module runs in poll mode by default, which is exposed to a 3-second race window in software, during which learning events in the switch hardware for a given L2 FDB entry can be lost. That can lead to corrupted L2 FDB entries and cause traffic hitting the corrupted L2 FDB entries to fail.

Conditions:
-- An L2 FDB entry is learned on Higig trunk.
-- Multiple L2 learning events happen on the L2 FDB entry during the 3-second race window in software.

Impact:
The traffic hitting the corrupted L2 FDB entry will be dropped by the switch.

Workaround:
Delete the corrupted L2 FDB entries and cause the switch to re-learn them.

To do so, identify the affected VLAN and flush L2 FDB entries on that VLAN using the following command: tmsh delete net fdb vlan {vlan_name}.

Fix:
A db variable switchboard.l2.mitigation was introduced to configure this feature.

-- A value of "enable" allows packets to be forwarded in the case of corrupted L2 FDB entries. Packets will be hashed on source and destination addresses. Enabling forwarding this way is only a temporary measure.

-- A value of "monitor" does not forward packets but will count packets which were affected by corrupted L2 FDB entries. The stat table switch/l2_mitgation, updated every 11 seconds, reports packet counts. Differences in packet counts are logged to /var/log/ltm.

-- A value of "disable" disables both forwarding and packet counting. Packet counts are reset.

655314 : When failing to load a UCS, the hostname is still changed, only in 12.1.2 or 13.0.0★

Component: TMOS

Symptoms:
The platform-migrate option to the UCS load command is supposed to reject UCS archives generated on BIG-IP software v10.x. It does this; however, the hostname of the BIG-IP system changes to the one in the UCS.

Conditions:
You are trying to do a platform-migrate load to 12.1.2 or 13.0.0 of a UCS originating on a system running v10.x.

Impact:
The hostname is changed, but no other configuration is modified.

Workaround:
Set the hostname back to its old value.

Fix:
The hostname is now left unmodified.

654109-2 : Configuration loading may fail when iRules calling procs in other iRules are deleted

Solution Article: K01102467

Component: Local Traffic Manager

Symptoms:
Loading of the configuration fail with a message indicating a previously deleted iRule cannot be found:

 01020036:3: The requested rule (/Common/rule_uses_procs) was not found.

Conditions:
- iRule A is calling another iRule B using proc calls
- iRule A is attached to a virtual server.
- Detaching and deleting iRule A.
- Loading the config (or performing config sync).

Impact:
iRules are still referenced after implicit deletion (via load).

654086-3 : Incorrect handling of HTTP2 data frames larger than minimal frame size

Component: Local Traffic Manager

Symptoms:
HTTP2 can vary frame size between 16K bytes (included) and 16 Mbytes (not included).

When a client sends a data frame spawning more than one TCP segment, the BIG-IP system incorrectly decrements the frame size twice from the receive window.

If the proxy flow control is disabled, this just creates an additional window update frame. If the proxy is in flow control, this causes a flow control error.

Conditions:
-- HTTP2 profile is configured on a virtual server.
-- Client sends a data frame larger than 16384 bytes, violating RFC. Note: The receiving maximum frame size of the BIG-IP is permanently set at 16384 bytes.

Impact:
HTTP2 resets the stream with FLOW_CONTROL_ERROR.

Workaround:
There is no workaround at this time.

Fix:
When a client sends HTTP2 a data frame exceeding a negotiated maximum frame size, the BIG-IP system correctly resets the stream.

654046-1 : BIG-IP as SAML IdP may fail to process signed authentication requests from some external SPs.

Component: Access Policy Manager

Symptoms:
When an external Service Provider (SP) canonicalizes authentication requests with the use of inclusive namespaces, a BIG-IP system used as SAML IdP may fail to process such requests. User's SSO will fail with following errors contained in /var/log/tmm:

err tmm1[13063]: 014d0002:3: 9c7802e1: SSOv2 Digest from SAML message is invalid
err tmm1[13063]: 014d0002:3: 9c7802e1: SSOv2 Error(12) Signature verification failed for SAML Authentication

Conditions:
- BIG-IP is used as SAML IdP.
- User performs SP-initiated SAML SSO.
- External SAML SP sends signed authentication request, in which canonicalization was done with use of inclusive namespaces.

Impact:
Users are unable to perform SAML SSO with certain external service providers.

Workaround:
None.

Fix:
Now BIG-IP APM as IdP SAML canonicalized authentication requests containing inclusive namespaces can be processed successfully.

653976-2 : SSL handshake fails if server certificate contains multiple CommonNames

Solution Article: K00610259

Component: Local Traffic Manager

Symptoms:
SSL server side handshake fails when the external server certificate's Subject field contains multiple CommonNames.

Conditions:
This issue occurs when both of the following conditions are met:
-- The external server certificate's Subject field contains multiple CommonNames.
-- The certificate does not contain subjAltName extension (or if it does, the same names are not included in the subjAltName's dNSName list).

Impact:
Connection with external server cannot be established. In case of forward proxy, bypass or intercept will fail.

Workaround:
In case of forward proxy bypass, configure IP address bypass instead of hostname bypass since IP address bypass check happens before SSL handshake.

The second option is to update the external server's certificate to include the list of CommonNames in subjAltName extension as dNSName.

Fix:
The system now checks all CommonNames in a certificate's Subject field instead of checking only the longest one in length.

---

653729-2 : Support IP Uncommon Protocol

Component: Advanced Firewall Manager

Symptoms:
A BIG-IP system can have CPU usage be non-uniformly distributed across the datapath (tmm) threads, such that the overall CPU usage is low, but individual datapath threads may show high usage of a subset of the CPUs on the system. This can be observed by viewing the per-CPU usage, and can manifest as spuriously dropped packets/flows.

Conditions:
A BIG-IP system receives packets that have uncommon IP protocols – those not parsed by the BIG-IP system.

Impact:
The packets are eventually dropped but may drive a subset of the CPUs in the system to very high usage. As CPU increases, potentially reaching 100%, then the BIG-IP system will start dropping packets and the system might eventually fail.

Workaround:
None.

Fix:
The system now supports packets that have uncommon IP protocols.

Behavior Change:
This change adds the capability of specifying various IP protocols as 'uncommon' protocols. Using this list of uncommon protocols can have the system mitigate an attack from uncommon protocols.

To do so, perform the following procedure:
1. Set the sys db tunable dos.uncommon.replace.illegal to true (it is false by default).
2. Set the 8 sys db tunables dos.uncommon.protocols[0-7] to specify which protocols should be considered uncommon (by default all protocols except TCP/UDP/ICMPv4/ICMPv6/SCTP - bits 1/6/17/58/132 are uncommon).
- dos.uncommon.protocols0 represents bits 31:0 of a 256-bit vector
- dos.uncommon.protocols1 represents bits 63:32 of a 256-bit vector
- dos.uncommon.protocols2 represents bits 95:64 of a 256-bit vector
- dos.uncommon.protocols3 represents bits 127:96 of a 256-bit vector
- dos.uncommon.protocols4 represents bits 159:128 of a 256-bit vector
- dos.uncommon.protocols5 represents bits 191:160 of a 256-bit vector
- dos.uncommon.protocols6 represents bits 223:192 of a 256-bit vector
- dos.uncommon.protocols7 represents bits 255:224 of a 256-bit vector

Setting the specific bit to '1' means that the specified protocol is considered 'uncommon', and setting the specific bit to '0' means that the specified protocol is not considered 'uncommon'.

Then the DoS vector IP Unknown Protocol can be used to mitigate an attack from the above-specified 'Uncommon Protocols'.

653453 : ARP replies reach front panel port of the B4450 blade, but fail to reach TMMs.

Component: TMOS

Symptoms:
ARP replies reach the front panel port of the B4450 blade, but fail to reach TMMs. This is caused by a L2 defect in the Broadcom Trident2+ switch B4450 blade uses.

Conditions:
The switch learned a corrupted L2 FDB entry on internal HiGig trunk.

Impact:
The traffic hitting the corrupted L2 FDB entry will be dropped by the switch.

Workaround:
Identify the affected VLAN and flush L2 FDB entries on that VLAN using the following command: tmsh delete net fdb vlan {vlan_name}.

Fix:
Resolved an issue on Broadcom Trident2+ switch B4450 blades use in which ARP replies reached the front panel port, but failed to reach TMMs.

Behavior Change:
A new BigDB variable is added to control in which mode the l2xmsg module in Broadcom SDK should run.

bcm56xxd.l2xmsg.mode: poll/fifo (default)

The BIG-IP system used to always run l2xmsg module in poll mode. Now, the BIG-IP system will run l2xmsg mode in fifo by default.

653234 : Many objects must be reconfigured before use when loading a UCS from another device.★

Component: TMOS

Symptoms:
Many objects are ignored by the platform-migrate option, and must be reconfigured before use when loading a UCS from another device.

Conditions:
UCS is being loaded from another device, using the platform-migrate option.

Impact:
Risk of configuration load failures.

652973-2 : Coredump observed at system bootup time when many DHCP packets arrive

Component: Policy Enforcement Manager

Symptoms:
During system bootup, system coredump is observed when many DHCP packets arrive before system is fully ready and many flow entry creation failures are observed

Conditions:
-- BIG-IP DHCP proxy is in forwarding mode.
-- DHCP relay agent in front of BIG-IP modifies giaddr field of DHCP packets to its own IP address.
-- DHCP packets arrive during system bootup and before system is fully ready (i.e., some VLANs, interfaces and routes are not fully up).

Impact:
System crash and coredump.

Workaround:
Make sure system has come up completely before sending DHCP packets to the system.

Fix:
Coredump no longer occurs under these conditions.

652968-2 : IKEv2 PFS CREATE_CHILD_SA in rekey does not negotiate new keys

Solution Article: K88825548

Component: TMOS

Symptoms:
During negotiations that use CREATE_CHILD_SA, IKEv2 will fail to send a KE in the payload when PFS (perfect forward security) is used in config.

Rekey in IKEv2 does not negotiate new keys; the PFS value in phase1-perfect-forward-secrecy is used in the first exchange, then this first key is re-used in later rekey negotiation. Vendor interop problems exist when PFS is required by the other peer.

Conditions:
Define phase1-perfect-forward-secrecy with value other than none. After IPsec SAs expire or are manually deleted, the CREATE_CHILD_SA phase to negotiate new keys has no KEi payload from the BIG-IP Initiator and so no new encryption key.

Impact:
PFS settings apply only to first negotiation and not to subsequent SA rekeys. PFS is therefore absent. When the BIG-IP enters CREATE_CHILD_SA with a third party IPsec peer, negotiation will fail if the peer requires PFS. Under the same conditions, BIG-IP to BIG-IP tunnels will not fail.

Workaround:
To resolve vendor interop problems, disable PFS in the IPsec policy of both peers.

Fix:
When phase1-perfect-forward-secrecy is configured with a value other than none, the BIG-IP will now perform PFS negotiation correctly. Now rekey with CREATE_CHILD_SA generates a new key using the same DH Group as the first exchange that creates the first SA.

Note: In the ipsec-policy configuration object, the ike-phase2-perfect-forward-secrecy option is relevant only to IKEv1 and has no influence on IKEv2 PFS rekeying.

652691-1 : Installation fails if only .iso.384.sig (new format signature file) is present★

Component: TMOS

Symptoms:
Tab completion only will complete the names of ISO images that have an old style signature format ("BIG-IP-version-build.iso.sig"), not the new style ("BIG-IP-version-build.iso.384.sig"). Then, installation will fail even if you type out the full name.

Conditions:
This only happens when signature checking is enabled for ISO images. You can determine this by looking at the value of the DB variable "liveinstall.checksig".

Impact:
Tab completion will not show the ISO image, and even if you type out the full name, the installation will fail. An error message will appear in "show sys software status" and /var/log/liveinstall.log .

Workaround:
Put both types of signature file (.iso.sig and .iso.384.sig) on the device.

Fix:
Tab completion and installation will now work if the old signature file format (.iso.sig) is missing, and only the new signature format (.iso.384.sig) is present.

652445-2 : SAN with uppercase names result in case-sensitive match or will not match

Solution Article: K87541959

Component: Local Traffic Manager

Symptoms:
SSL certificates with SAN domain names with uppercase characters will fail to match SNI requests for that domain name.

Conditions:
Multiple client-ssl profiles configured with SNI associated with a single virtual where the SAN (Subject Alternative Name) contains DNS names with uppercase characters.

Impact:
SNI does not match, resulting in the wrong certificate being returned to the client, which potentially results in a security warning in the client application due to a non-matching domain.

Workaround:

652094-2 : Improve traffic disaggregation for uncommon IP protocols

Solution Article: K49190243

Component: TMOS

Symptoms:
The traffic of uncommon IP protocols on VLAN running default DAG is sent to one TMM by default.

Conditions:
Traffic of uncommon IP protocols on VLAN configured with default DAG.

Impact:
Traffic for uncommon IP protocols not distributed evenly among available processing units.

Workaround:
None.

Fix:
The system now correctly distributes traffic for uncommon IP protocols based on src IP and dest IP.

The traffic of uncommon IP protocols on VLAN running default DAG is sent to one TMM by default. This DAG enhancement allows the default DAG to disaggregate traffic of uncommon IP protocols based on src IP and dest IP. Two more DB variables are added to control DAG behavior for uncommon IP protocols.

ipproto.lookupip: enable/disable (default)
ah.lookupip: enable/disable (default)

Setting ipproto.lookupip to enable will disaggregate uncommon IP protocols based on src IP and dest IP. DB ipproto.lookupip applies to all IP protocols except for TCP, UDP, SCTP, IGMP, AH, ESP, GRE, ICMP, ICMPv6.

Setting ah.lookupip to enable will disaggregate AH traffic based on src IP and dest IP.

Behavior Change:
The traffic of uncommon IP protocols on VLAN running default DAG is sent to one TMM by default. This DAG enhancement allows the default DAG to disaggregate traffic of uncommon IP protocols based on src IP and dest IP. Two more DB variables are added to control DAG behavior for uncommon IP protocols.

652052-3 : PEM:sessions iRule made the order of parameters strict

Component: Policy Enforcement Manager

Symptoms:
In the versions before 12.0, the order of parameters for "PEM::SESSIONS" rule was flexible. It was made strict because of the new validation infrastructure in 12.0. This breaks some existing iRules.

The system will report a validation error such as:

01070151:3: Rule [/Common/test_irule] error: /Common/test_irule:2: error: ["invalid argument subscriber-type"][PEM::session create $ip subscriber-type e164 user-name $user imsi $imsi subscriber-id $callingstationid]

Conditions:
Some parameters, for example, subscriber-id come before the parameter user-name.

Impact:
Configuration that was valid in earlier versions is not accepted in newer versions. This may result in the configuration failing to load during an upgrade and return an MCP validation error.

Workaround:
Change the order of the parameters.

652004-2 : Show /apm access-info all-properties causes memory leaks in tmm

Solution Article: K45320415

Component: Access Policy Manager

Symptoms:
When tmsh is used to view session information, memory will leak on each request to pull the session information from tmm. This is a small leak but can be significant issue when all sessions are examined or the sessions are examined multiple times in a short time interval.

Conditions:
when using show /apm access-info all-properties

Impact:
Memory will leak in tmm daemons. This affects all modules that use tmm.

Workaround:
The only workaround is not to use the mcp interface by tmm daemon, or to restart the tmms periodically after using the interface multiple times.

Fix:
Accessing APM session variables via tmsh (e.g., 'tmsh show /apm access-info all-properties') no longer causes a small TMM memory leak.

---

651910-2 : Cannot change 'Enable Access System Logs' or 'Enable URL Request Logs' via the GUI after upgrading from 12.x to 13.0.0 or later

Component: Access Policy Manager

Symptoms:
You cannot change the 'Enable Access System Logs' and 'Enable URL Request Logs' properties via the GUI.

Conditions:
After upgrade from 12.x to 13.0.0 (where these new fields were added) or later.

Impact:
You cannot change 'Enable Access System Logs' and 'Enable URL Request Logs'.

Workaround:
Manually add the properties via tmsh. To do so, follow these steps (substituting your affected log setting for abc in the following example):

modify log-setting abc access add { general-log { publisher sys-db-access-publisher } }
modify log-setting abc url-filters add { test_logsetting_swg { enabled true publisher sys-db-access-publisher }}

Fix:
Now it is possible to use the GUI to successfully use and configure log-setting objects that were created with tmsh.

651901-2 : Removed unnecessary ASSERTs in MPTCP code

Component: Local Traffic Manager

Symptoms:
There are many scenarios that call ASSERT in the MPTCP code, many of which can be handled without using ASSERT.

Conditions:
A virtual server is configured with a TCP profile with MPTCP enabled.

Impact:
If an ASSERT fails, traffic is disrupted while TMM restarts.

Workaround:
There is no workaround at this time.

Fix:
Replaced many ASSERTs with other mitigations that allow TMM to continue running.

---

651772-3 : 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.

651681-4 : Orphaned bigd instances may exist (within multi-process bigd)

Solution Article: K49562354

Component: Local Traffic Manager

Symptoms:
When multi-process 'bigd' is configured, orphaned 'bigd' instances may be exit; such as an orphaned 'bigd.1' alongside the active 'bigd.1'.

Conditions:
-- db variable Bigd.NumProcs to 2 or higher.
-- System monitors with long timeouts (such as ~183 seconds or longer), might also be relevant.

When 'bigd' manages monitor configurations that results in no monitoring activity for a long time (such as due to long monitor timeouts), the operating system may temporarily suspend (and later resume) the 'bigd' process. The system might treat the 'bigd' process as if it were "hung", and start another 'bigd' instance without explicitly terminating the suspended 'bigd' process.

Impact:
The suspended 'bigd' process consumes process memory. The process might be suspended (consuming no CPU resources), or running, which might result in "double-monitoring" the resources assigned to that 'bigd' process.

Note: If double-monitoring occurs, monitor status should be correct, but the double-monitoring unnecessarily consumes extra resources.

Workaround:
Configure 'bigd' to run as a single process. To do so, set the db variable Bigd.NumProcs to 1.

Shortening monitor timeouts can reduce the possibility of a 'bigd' process being (temporarily) suspended by the operating system.

Fix:
Multi-process 'bigd' no longer produces orphaned (suspended) process instances.

651651-3 : bigd can crash when a DNS response does not match the expected value

Solution Article: K54604320

Component: Local Traffic Manager

Symptoms:
bigd can crash when a response returned from a DNS request does not match the expected value.

Conditions:
Monitoring DNS server(s), or using FQDN.

Impact:
Potential bigd core and restart; may cause endless restart loop as long as DNS monitor instance is configured.

Workaround:
No workaround at this time.

Fix:
Prevented bigd from crashing when a response returned from a DNS request does not match the expected value.

---

651640-3 : queue full dropped messages incorrectly counted as responses

Component: Service Provider

Symptoms:
negative number of active response messages reported on sipsession profile stats

Conditions:
If a request message is dropped because the sip filter's ingress message queue is full, the wrong stats is incremented

Impact:
Counting the dropped request messages as response messages causes the calculation of the accepted response messages to be incorrectly calculated, thus producing a negative value.

Fix:
correct stats fields are incremented

---

651476 : bigd may core on non-primary bigd when FQDN in use

Component: Local Traffic Manager

Symptoms:
When using FQDN node/pool member resolution, a non-primary bigd process may core under certain circumstances. A non-primary bigd is any process instance other than zero in a multi-bigd scenario, or any bigd process on a non-primary blade in a chassis.

Conditions:
FQDN is in use.

Impact:
bigd may core and be restarted in a loop, causing some monitor instances to not be serviced. This may cause node/pool member flapping, or may cause certain nodes or pool members to be effectively not monitored.

Workaround:
Use static IPs instead of FQDN for node/pool member address assignment.

Fix:
Known causes of the bug have been fixed.

---

651413-2 : tmsh list ltm node does not return an error when node does not exist

Component: TMOS

Symptoms:
TMSH does not post an error message in response to the tmsh command to list a specific, non-existent LTM node, or when listing a set of non-existent nodes using regular expressions.

Conditions:
-- Running the command: tmsh list ltm node.
-- Running a regular expression to list a set of nodes.
-- The specified node does not exist.

Impact:
The command produces no output or error message. No indication of why there is no output, nor is there a description of the possible error condition.

Workaround:
None.

Fix:
TMSH now posts the appropriate, node-not-found error message when LTM nodes do not exist when running the command: tmsh list ltm node.

651135-4 : LTM Policy error when rule names contain slash (/) character★

Solution Article: K41685444

Component: Local Traffic Manager

Symptoms:
Beginning with v12.0.0, there has been additional validation for LTM Policy rule names to allow only certain valid characters. Prior to v13.1.0, the slash (/) character was included in the set of valid characters.

But because the slash character is used as a delimiter in the BIG-IP virtual path hierarchy (e.g., /Common/my_policy/my_rule), extra slashes in a rule name causes validation problems because the rule appears to the system as having additional path segments.

Conditions:
LTM Policy rule contains the slash (/) character.

Impact:
Configuration will not load.
Configuration may load, but admin GUI may not show policy rule.

Workaround:
In the bigip.conf file, the LTM Policy rule names can be manually edited to either remove the illegal character or to substitute a valid character.

For example, the following policy won't load because the rule name contains a slash (/) character:
   
    ltm policy mypolicy {
    ...
       rules {
          /testperson/a {
    ...
    }

But it will load when the slash (/) characters are changed to a legal character, such as underscores (_):
    ltm policy mypolicy {
    ...
       rules {
          _testperson_a {
    ...
    }

Fix:
For upgraded configurations, the roll-forward process will automatically translate slash (/) to underscore (_) in LTM Policy rule names. When creating new rules, validation will not succeed if a rule name contains an illegal character, such as a slash, so the issue will be prevented.

651106 : memory leak on non-primary bigd with changing node IPs

Component: Local Traffic Manager

Symptoms:
On BIG-IP systems with the multiple blades, or a BIG-IP system with multiple bigd processes running (bigd.1, bigd.2, etc.), if the system has FQDN nodes configured, all secondary bigd processes will consume an unusually high amount of memory, and bigd cores may exist when the FQDN node IP addresses change frequently.

Conditions:
FQDN nodes configured on a system, and the system (as a whole) has multiple bigd processes running, either across multiple blades or multiple bigd instances on a single blade. As configuration changes are made to FQDN nodes causing IP addresses to change, bigd on the non-primary places memory consumption may be unusually high.

Impact:
bigd memory leak; possible bigd crash.

Workaround:
Mitigation: use static IP nodes and pool members rather than FQDN.

---

651001-1 : massive prints in tmm log: "could not find conf for profile crc"

Component: Advanced Firewall Manager

Symptoms:

Conditions:
1. Have dos profile attached to vs. dos profile does not have dos application enabled.
2. Have ASM policy attached to VS with Web Scraping on/session hijacking/session awarness with DID collection/brute force with DID collection.

Impact:
Massive prints in tmm log that can cause tmm to abort. Traffic disrupted while tmm restarts.

Workaround:
Have DOS application enabled (even if doing nothing).

Fix:
disable prints.

Impact:
An initial coredump (or HA switchover) forces multiple core dumps. Traffic disrupted while tmm restarts.

---

650349 : Creation or reconfiguration of iApps will fail if logging is configured

Solution Article: K50168519

Component: TMOS

Symptoms:
If logging destination of any type is configured (ArcSight, IPFIX, remote high speed logging, etc.), creation or reconfiguration of iApps will fail. The following error will be reported in /var/log/webui.log and displayed in the GUI: The connection to mcpd has been lost, try again.

Conditions:
Logging is configured: filter, destination, and publisher.

Impact:
Cannot create new iApps or reconfigure existing ones.

Workaround:
Remove logging configuration.

Fix:
Can now create or reconfigure iApps if logging is configured.

---

650317-3 : The TMM on the next-active panics with message: "Missing oneconnect HA context"

Component: Local Traffic Manager

Symptoms:
The next-active TMM panics with message: "Missing oneconnect HA context" on a virtual which doesn't have one-connect on the active.

Conditions:
A mirrored virtual is configured with one-connect on the next-active but no one-connect profile is present on the active. This can occur when the config-sync connection between peers is down or auto-sync on the device group is disabled. The next-active expects a one-connect HA context but the active does not send it.

Impact:
Connections on the active are not mirrored while the next-active restarts.

Workaround:
Resolving configuration differences between the active and next-active will prevent this panic.

Fix:
Mirrored connections which fail to find an HA context on the next-active are not established on the next-active.

650292-2 : DNS transparent cache can return non-recursive results for recursive queries

Component: Local Traffic Manager

Symptoms:
If a non recursive query is cached by the DNS transparent cache, subsequent recursive queries provide the non-recursive answer.

Conditions:
DNS transparent cache that receives a non-recursive query whose result is stored in the cache.

Impact:
Non recursive responses for recursive requests.

Workaround:
An iRule can be attached to the listener to disable the cache if the "rd bit" is not set in the DNS request.

Fix:
The RD bit is now handled as expected. If a recursive request is received, a non-recursive cached entry is ignored, and replaced, when the recursive request is answered.

650074-1 : Changed Format of RAM Cache REST Status output.

Component: Local Traffic Manager

Symptoms:
The REST API returned cache contents in displayable form, not tagged field form.

Conditions:
Using REST API.

Impact:
Text must be parsed as if the caller plans to post-process it.

Workaround:
To present the data in some other format, the text can be displayed as is, but must be parsed as if the caller plans to post-process it.

Fix:
Now RAM Cache REST Status output is returned in field format, and must be parsed by a JSON parser and formatted for display. If you were using the previous format, you must now parse the JSON and re-format the data for display.

Behavior Change:
REST API calls for ramcache stats now returns data as formatted JSON.

650002-1 : tzdata bug fix and enhancement update

Component: TMOS

Symptoms:
There have been changes to timezone data that impact tzdata packages:

* Mongolia no longer observes Daylight Saving Time (DST).

* The Magallanes Region of Chile has moved from a UTC-04/-03 scheme to UTC-03 all year. Starting 2017-05-13 at 23:00, the clocks for the Magallanes Region will differ from America/Santiago.

Conditions:
-- Mongolia during DST portion of the year.
-- Comparing clock times in the America/Santiago zone with those in the Magallanes Region.

Impact:
Timezone data provided in tzdata will not match the area's time. Clocks for the Magallanes Region will differ from America/Santiago (its current timezone).

Workaround:
None.

Fix:
To accommodate for Mongolia no longer observing DST, the new America/Punta_Arenas zone was created. Changes were also made to support other timezone changes.

* The zone1970.tab file has been added to the list of files to be installed with the tzdata packages installation.

Note: Users of tzdata are advised to upgrade tzdata to zdata-2017b-1.el6

649949-1 : Intermittent failure to do a clean install on iSeries platforms from USB DVD-ROM★

Component: TMOS

Symptoms:
Following the instructions at https://support.f5.com/csp/article/K13117 will occasionally fail on iSeries platforms, with the system being unable to find the installation media.

If this happens, running the following command will fail.

  image2disk --instslot=HD1.1 --setdefault --nosaveconfig

Conditions:
This can occur on iSeries platforms while performing a clean installation.

Impact:
The /dev/cdrom softlink points to the virtual CD-ROM drive in iSeries platforms instead of the physical USB DVD-ROM drive. This prevents image2disk from automatically finding the installation media.

Workaround:
After the failure, while in MOS, determine USB CDROM device name, mount it, and tell image2disk specifically where it is:

bash (try 'info') / > dmesg | grep "sr0\|sr1"
sr0: scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda tray <-- cdrom name
sr 6:0:0:0: Attached scsi CD-ROM sr0
sr1: scsi-1 drive
sr 7:0:0:0: Attached scsi CD-ROM sr1

bash (try 'info') / > mount -r -t iso9660 /dev/srX /cdserver
bash (try 'info') / > image2disk --instslot=HD1.1 --nosaveconfig /cdserver

In the mount command, replace "/dev/srX" with whichever device is the physical drive.

649866-1 : fsck should not run during first boot on public clouds

Component: TMOS

Symptoms:
Although it is not needed, filesystem check runs during the first boot. This increases the boot time, especially for images that were created more than 180 days before the first boot, because twice year, booting up runs a more comprehensive fsck operation.

Conditions:
This occurs when booting up public cloud configurations of Virtual Edition (VE).

Impact:
Potentially unacceptable long boot times.

Workaround:
None.

Fix:
fsck does not run during first boot on public cloud configurations of VE. Running fsck is postponed until the second boot. If the more comprehensive fsck operation is required, it runs during the second boot as well.

649617-2 : qkview improvement for OVSDB management

Component: TMOS

Symptoms:
The user can configure ovsdb-server in the BIG-IP system to communicate with an OVSDB-capable controller.

If the user wants the BIG-IP system to connect to an OVSDB-capable controller via a SSL connection, the user needs to configure a certificate and a certificate key in the TMSH command "sys management-ovsdb". Later on, if the user invokes qkview to collect system information, the configured certificate key can be collected in qkview.

Conditions:
The following conditions need to be met:

- BIG-IP has the SDN services license.

- The TMSH command "sys management-ovsdb" is set to "enabled". Note that this is set to "disabled" by default.

- The TMSH command "sys management-ovsdb cert-key-file" is set to a certificate key. Note that this is set to "none" by default.

Impact:
If the user invokes qkview to collect system information, the certificate key configured in the command "sys management-ovsdb cert-key-file" will be collected in qkview.

Workaround:
If OVSDB management is currently set to "enabled" in the BIG-IP system, then the user can reset "sys management-ovsdb cert-file" and "sys management-ovsdb cert-key-file" to "none" before calling qkview to collect system information.

In general, if OVSDB management has ever been set to "enabled", the user with the bash shell access can check if the file /var/run/openvswitch/BIG-IP_ovs_cert_key exists and delete it before calling qkview to collect system information.

Fix:
The certificate key configured in the "sys management-ovsdb" will not be collected when invoking qkview.

649613-3 : Multiple UDP/TCP packets packed into one DTLS Record

Component: Access Policy Manager

Symptoms:
The system converts the server provided packet into PPP buffers. These PPP packets are used to pack into DTLS records. Currently there is a limit of about 14 KB of DTLS records, such that the system can pack multiple PPP records into one DTLS record.

However, creating bigger DTLS record can cause server IP Fragmentation. In the lossy environment, losing one IP fragment can cause the complete DTLS record to be lost, resulting in poor performance.

Conditions:
Multiple UDP/TCP packets packed into one DTLS Record.

Impact:
In networks with packet losses, the APM end-user application might suffer poor network performance.

Workaround:
None.

Fix:
DTLS performance has been improved in lossy or high latency networks by optimizing the number of encoded ppp records inside of DTLS records.

---

649571-1 : Limits set in Server SSL Profile are not enforced if the server ignores BIG-IP's renegotiation ClientHello

Component: Local Traffic Manager

Symptoms:
The BIG-IP system does not act on the absence of renegotiation.

Conditions:
A BIG-IP system acts as TLS client, a TLS server ignores renegotiation request. Finite TLS session data or time limits are configured in Server SSL Profile on the BIG-IP system.

An example of such a TLS server is Apache/2.4.10 on Fedora Linux.

Impact:
Limits, such as data limits ("Renegotiate Size" in Server SSL) or time limits ("Renegotiate Period" in Server SSL) are not enforced with finite "Handshake Timeout".

Workaround:
None.

Fix:
BIG-IP system acting as TLS client (Server SSL Profile) now shuts down the connection if a TLS server did not continue with TLS renegotiation within "Handshake Timeout" seconds after the ClientHello, corresponding to the renegotiation initiation, was sent by the BIG-IP system.

---

648715-2 : BIG-IP i2x00 and ix4x00 platforms send LLDP, STP, and LACP PDUs with a VLAN tag of 0

Component: Local Traffic Manager

Symptoms:
LACP, STP, and LLDP PDUs sent from either of the i2x00 or i4x00 platforms have a VLAN tag added to the PDU when they shouldn't.

Conditions:
Provision any of the three protocols: LLDP, STP, or LACP and the PDU sent by the BIG-IP will incorrectly have a VLAN tag with a tag-id of 0 added to the PDU.

Impact:
Some 3rd party devices may reject the packet. This will adversely affect operation of the affected protocol.

Workaround:
None.

Fix:
This release ensures that the VLAN tag is stripped before the PDU is sent onto the wire.

---

648617 : JavaScript challenge repeating in loop when URL has path parameters

Component: Advanced Firewall Manager

Symptoms:
The JavaScript challenge is repeating in a loop on URLs which have path parameters (when the URL contains the ';' character). The request never reaches the back-end server.
This happens in the following challenges:
* Proactive Bot Defense with Suspicious Browsers enabled
* Client-Side Integrity Defense
In the rest of the challenges, the challenges will succeed, but POST requests will not be reconstructed correctly and sent as a multipart message to the back-end server.

Conditions:
URLs contain the ';' character, AND:
Either:
* Proactive Bot Defense with Suspicious Browsers enabled, OR
* Client-Side Integrity Defense is enabled and is used as a DoSL7 mitigation during an attack.

Impact:
Requests with ';' character will be blocked and the browser will repeat the challenge in a loop.

Workaround:
None

Fix:
The JavaScript challenge no longer gets stuck in a loop on URLs which have path parameters.

---

648544-5 : HSB transmitter failure may occur when global COS queues enabled

Solution Article: K75510491

Component: TMOS

Symptoms:
An HSB transmitter failure may occur if global COS queues enabled. The HSB transmitter failure is logged in the TMM log files.

Conditions:
With global COS queues enabled, the HSB's watchdog loopback packets are sent on HSB ring 2, instead of ring 0. If HSB ring 2 is heavily utilized, this could cause the loopback packets to be dropped. If this occurs, then the watchdog may trigger an HSB transmitter failure.

Impact:
If this issue occurs then the BIG-IP is rebooted.

Workaround:
Do not use global COS queues.

Fix:
Loopback packet priority is now set during runtime to guarantee transmit on mgmt ring 0.

---

648320-3 : Downloading via APM tunnels could experience performance downgrade.

Component: Local Traffic Manager

Symptoms:
Multiple DTLS records can be packed into one UDP packet. When packet size is too large, packet fragmentation is possible at IP layer. This causes high number of packet drops and therefore performance downgrade.

Conditions:
When downloading using APM tunnels.

Impact:
High number of packet drops and inferior performance.

Workaround:
None.

Fix:
One DTLS record is now contained in each UDP packet to avoid packet fragmentation.

---

648286-2 : GSLB Pool Member Manage page fails to auto-select next available VS/WiP after pressing the add button.

647108-1 : Deletion of saml-idp-connector may fail depending on the order in which related objects are deleted within a transaction

Component: Access Policy Manager

Symptoms:
The system posts messages similar to the following even when the server associated to the connector is also being deleted in the same transaction:
01070734:3: Configuration error: apm aaa saml-idp-connector: Cannot delete saml-idp-connector /Common/saml_connector because it is being used by aaa-saml-server (/Common/saml_server_test1

Conditions:
When deleting saml-idp-connector first then the associated saml server.

Impact:
Cannot delete saml-idp-connector and associated server in that specific order.

Delete saml server first and then delete the saml connector.

Fix:
Now saml-idp-connector can be deleted with associated objects in any order from a transaction.

---

646928-1 : Landing URI incorrect when changing URI

Component: Access Policy Manager

Symptoms:
User accesses resource1, and an access policy starts. Before the policy completes, the user changes to resource2. There is a warning page that the session already exists, and the user clicks to create a new session. After the policy completes, the user is directed to the landing URI of the resource1.

Conditions:
Attempting to change landing URI in the middle of an access policy

Impact:
End-user is inconveniently directed to the first resource instead of the second.

Fix:
Now the "To open a new session, please click here." link on the APM logout page reflects the last used landing URI rather than the first used landing URI.

---

646890-1 : IKEv1 auth alg for ike-phase2-auth-algorithm sha256, sha384, and sha512

Solution Article: K12068427

Component: TMOS

Symptoms:
Changing the IKEv1 phase2 authentication algorithm to sha256, sha384, or sha512 does not work immediately, without a restart of the tmipsecd daemon.

Conditions:
If you change the ike-phase2-auth-algorithm attribute (inside an instance of ipsec-policy) to a value of sha256, sha384, or sha512, this causes a parse error when received by racoon. Thus the change does not take affect without a racoon restart.

Impact:
Cannot switch IKEv1 ipsec-policy to sha256, sha384, or sha512 authentication without either restarting BIG-IP or restarting tmipsecd.

Workaround:
Restarting the tmipsecd daemon causes a restart of all racoon processes, which causes the config to be re-read and then IKEv1 IPsec works correctly with SHA authentication algorithms.

Fix:
Now tmipsecd sends the correct incremental config description of SHA authentication algorithms to racoon, so that IKEv1 ipsec-policy reconfiguration works immediately without requiring a restart of tmipsecd.

646604-5 : 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.

Disable roll-forward upgrade of ASM traffic data before upgrade:

tmsh modify sys db ucs.asm.traffic_data.save value disable

Fix:
ASM completes roll-forward upgrade with traffic data correctly, even after upgrade process is interrupted.

---

646443-1 : Ephemeral Node may be errantly created in bigd, causing crash

Solution Article: K54432535

Component: Local Traffic Manager

Symptoms:
When FQDN Ephemeral Nodes are being used at the same time as static Node objects, and there is change in those objects, either via DNS resolver changes or manual changes to static nodes, there exists a chance where one may be misidentified as the other during an update, causing a crash in bigd.

Conditions:
FQDN Nodes and Static Nodes being used. Change in node settings or creation/deletion of nodes.

Impact:
Bigd crashes, causing interruption in monitoring.

Workaround:
Avoid use of FQDN Nodes and Pool Members; use only static-IP Nodes/Members instead.

Fix:
Fixed case where misidentification may occur, resulting in bigd running without crashing.

645805 : LACP PDUs generated by lacpd on i4x00/i2x00 platforms contain bad ethernet src mac address

Component: TMOS

Symptoms:
LACP PDUs generated by the 'lacpd' on the i4x00 & i2x00 platforms contain the wrong Ethernet source MAC address.

Conditions:
LACP configured on an trunk interface on i4x00 or i2x00 platforms.

Impact:
Some Cisco and Juniper switches discard these PDUs. They send PDUs as if the BIG-IP is not transmitting with a all-zeros 'Partner' section System ID. This renders LACP inoperable, and simply does nothing if the far end is configured for 'Passive'.

Fix:
Insure correct Source MAC address is inserted into the PDU.

---

645723-2 : Dynamic routing update can delete admin ip route from the kernel

Solution Article: K74371937

Component: TMOS

Symptoms:
Routes obtained from dynamic routing (BGP, etc.) can replace existing management route for the admin IP address, making the BIG-IP lose its management route. Static routes created via TMSH can replace management route.

Conditions:
Using TMSH to create "net route" that matches management network, or dynamic routing accepts a route that matches the management network.

Impact:
Losing the management network route, and potential loss of access to the BIG-IP via the management network.

Workaround:
Don't accept route updates for the management network. Don't create static routes for the management network.

Fix:
Management network admin IP address is now protected from being overwritten.

---

645717 : UCS load does not set directory owner

Component: TMOS

Symptoms:
When loading a UCS file the directory /etc/ssh will become owned by the first user in the UCS with an .authorized_keys file.

Conditions:
UCS loaded that contains users with .authorized_key files

Impact:
Ownership of /etc/ssh is set to a non-root user after UCS load. This does not interfere with normal system operation or SSH authentication but does not follow secure coding practices

Workaround:
Ownership of on /etc/ssh can be restored with the command: chown root /etc/ssh

Fix:
UCS load now explicitly sets ownership of the /etc/ssh directory to root.

When mcpd debug logging is enabled, mcp messages sent to or received from the bigd daemon are logged with a username of "(user %-P)" or "(user %-S)" instead of "(user %bigd.#)" [where # is the bigd process index] or "(user %bigd)".

Conditions:
mcpd debug messages with the "(user %-P)" identifier are logged on affected BIG-IP versions when mcpd debug logging is enabled and multiple instances of bigd are running.
mcpd debug messages with the "(user %-S)" identifier are logged on affected BIG-IP versions when mcpd debug logging is enabled and a single instance of bigd is running.

Impact:
Confusion about which daemon is referenced in mcpd debug logs with username "(user %-S)" or "(user %-P)".

Fix:
mcpd debug messages sent to or received from the bigd daemon are correctly logged with a username of "(user %bigd.#)" [where # is the bigd process index] or "(user %bigd)".

645197-3 : Monitors receiving unique HTTP "success" response codes may stop monitoring after status change

Component: Local Traffic Manager

Symptoms:
Monitors that return unique HTTP/1.1 200 codes (indicating success) will accumulate in the monitor history; upon monitor status change (such as to "fail"), this history is sent (from 'bigd' to 'mcpd') to indicate that monitor's new-status, plus historical context. This history may grow too large if no monitor status is detected for an extended time (such as days or weeks) when unique status codes are returned from the web server and accumulated in the history. Upon a monitor status change (such as from "success" to "fail"), notification from 'bigd' to 'mcpd' will fail due to this too-large history, resulting in the monitor remaining in its previous state (i.e., "success"). 'bigd' properly records the monitor status and continues to monitor; but 'mcpd' was not notified of that status change (due to message-send failure from the history being too large).

This is typically not an issue when the web server returns the same HTTP/1.1 200 code (indicating "success"), as 'bigd' will elide/merge the response-value into the monitor history (so the history does not continue to grow). However, for web servers generating a unique value for each success code (for example, by appending an always-unique transaction ID to the end of the HTTP/1.1 200 response), the history will continue to grow for that monitor until a status-change is detected.

Conditions:
Web server returns unique HTTP/1.1 200 (success) codes, such as an included date/time stamp; and success history is accumulated for that monitor without status-change for extended time (typically days-or-weeks); followed by a monitor status change (such as from "success" to "fail").

Impact:
The monitor will remain in the "success" state, as the status-change will be "lost" ('bigd' properly recognizes the changed monitor status, but 'mcpd' is not notified of the change). The system may eventually self-correct, such as when 'bigd' detects further monitor status changes, and again forwards status-change notifications for that monitor to 'mcpd'.

Workaround:
Modify the web server configuration to not respond with unique HTTP/1.1 200 codes; thus, receiving the same return-code will elide/merge with previously accumulated values in the monitor history.

Fix:
HTTP/1.1 200 codes with unique values accumulate for limited history, rather than unbounded history, such that monitor status change notifications are always recorded.

645179-6 : Traffic group becomes active on more than one BIG-IP after a long uptime

Solution Article: K42751321

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.

645058-3 : Modifying SSL profiles in GUI may fail when key is protected by passphrase

Component: Local Traffic Manager

Symptoms:
When a client SSL profile has a Certificate Key Chain (CKC) entry with a passphrase-protected key, attempting to modify/update the profile via the GUI may fail, and produce an error similar to the following:

01070313:3: Error reading key PEM file <Key_File_Path> for profile <Profile_Name>: error:0906A068:PEM routines:PEM_do_header:bad password read.

This can occur even when the passphrase already in the SSL profile is correct.

Conditions:
Upgrading a BIG-IP system from a version prior to BIG-IP v11.5.0 to v11.5.0 or later, while having a passphrase-protected key specified in the profile.

Alternately, creating an SSL profile with a custom cert-key-chain name that references a passphrase-protected key, e.g.:

tmsh create ltm profile client-ssl example-profile defaults-from clientssl cert-key-chain replace-all-with { no { cert protected.crt key protected.key passphrase password } }

Impact:
User cannot update client SSL profile via the GUI.

Workaround:
Modifications to the profile can be made from tmsh. Alternately, delete the CKC and recreate it.

Fix:
User can now update client SSL profile after upgrading a BIG-IP system from a version prior to BIG-IP v11.5.0 to v11.5.0 or later, while having a passphrase-protected key specified in the profile.

645036-3 : Removing pool from virtual server does not update its status

Solution Article: K85772089

Component: Local Traffic Manager

Symptoms:
Removing a pool from a virtual server does not update the virtual server's status.

Conditions:
1) Create a pool and assign a monitor to it.
2) Ensure the pool goes green.
3) Create a virtual server without assigning the pool to it.
4) Ensure the virtual server stays blue (unknown).
5) Associate the pool to the virtual server.
6) Ensure the virtual server goes green (available).
7) Remove the pool from the virtual server.
8) The virtual server should go back to blue (unknown); however, it doesn't and stays green.

Impact:
The virtual will appear to be associated with a monitored pool when it is not. This should have no functional impact on the virtual server, since a virtual server without a pool has no traffic to pass, and associating a pool with the virtual server will reflect the pool status.

Workaround:
Restart the BIG-IP system. The status should be blue/unchecked once again after the BIG-IP is restarted.

Note: Restarting the BIG-IP system might have an impact on existing traffic. Because this issue is cosmetic, this workaround is not recommended for BIG-IP systems in production.

Fix:
Associating a pool with the virtual server now correctly updates the virtual server status.

644975-4 : /var/log/maillog contains errors when ssmtp is not configured to use a valid mailhost

Component: TMOS

Symptoms:
Entries in /var/log/maillog similar to the following:
err sSMTP[25793]: Unable to connect to "localhost" port 25.

Conditions:
This happens when certain crontab configuration files do not specify MAILTO="" at the top, and some of the scripts appearing in those files output something to STDOUT or STDERR. This causes the system to try to send an email with that output, which will fail when ssmtp is not configured to use a valid mailhost.

Impact:
Error messages logged to /var/log/maillog. Note that the maillog file is rotated so it doesn't fill up the /var/log volume.

Workaround:
1) Run the "crontab -e -u root" command; this will open the root user's crontab configuration in your default text editor.

2) Move the MAILTO="" line to the top of the file, right under the "# cron tab for root" banner.

3) Save the file and exit the text editor to install the root user's new crontab configuration.

4) Using a text editor of your choice, replace MAILTO=root with MAILTO="" in the /etc/crontab file.

5) Using a text editor of your choice, replace MAILTO=root with MAILTO="" in the /etc/cron.d/0hourly file.

6) To verify that MAILTO=root does not appear anywhere else, run the following command: grep -i -r mailto /etc/cron*.

7) If the previous command shows MAILTO=root still appears in some files, also modify those file so that MAILTO=root becomes MAILTO="".

Fix:
The crontab configuration files now specify MAILTO="" at the top, so the /var/log/maillog errors no longer occur.

644970-1 : Editing a virtual server config loses SSL encryption on iSession connections

Component: Wan Optimization Manager

Symptoms:
Editing a virtual server configuration causes iSession connection resets or unencrypted iSession connections to be established, because the virtual server's dynamically configured default server-ssl profile has been deleted.

Conditions:
A virtual server has a server-side iSession profile with data-encrypt enabled. This virtual server also lacks client-ssl and server-ssl profiles.

Impact:
After editing the virtual server, iSession connections fail to be established if the destination iSession listener has a client-ssl profile with allow-non-ssl disabled. If the destination iSession listener has allow-non-ssl enabled, unencrypted iSession connections are established.

Workaround:
Modify the virtual server's configured server-side iSession profile. For example toggle the iSession profile from A to B and then back to A.

Fix:
Editing a virtual server configuration no longer deletes
an iSession dynamically configured default server-ssl profile.

644946-2 : Enabling mirroring on SIP or DIAMETER router profile effects per-client connection mode operation

Solution Article: K05053251

Component: Service Provider

Symptoms:
When the mirror flag is enabled in the siprouter and diameterrouter profiles, outgoing per-client create connection will be usable by any client connection from the same IP address.

Conditions:
This occurs when the mirror flag is enabled in the siprouter and diameterrouter profiles.

Impact:
In the siprouter and diameterrouter profiles, enabling mirroring incorrectly enables the internal ignore_peer_port flag, which causes the router to not consider the remote port of the client side connection when determining which of an outgoing per-client connection can be used for forwarding messages.

Workaround:
None.

Fix:
The ignore_peer_port flag is no longer affected by the setting of the mirror flag, which is correct functionality.

644873-2 : ssldump can fail to decrypt captures with certain TCP segmenting

Solution Article: K97237310

Component: Local Traffic Manager

Symptoms:
ssldump fails to decrypt a capture. In rare circumstances, ssldump can crash.

The ssldump might display output similar to the following:
1 25 0.4781 (0.0000) S>CShort record
Unknown SSL content type 224
1 26 0.4781 (0.0000) S>CShort record
Unknown SSL content type 142
...
1 30 0.4781 (0.0000) S>CShort record
1 31 0.6141 (0.1359) S>CV231.213(45857) application_data

Conditions:
ssldump is decrypting traffic where an SSL record header spans TCP segments.

Impact:
ssldump can fail to fully decrypt the capture starting at the frame where the SSL record spans a TCP segment. Depending on the remaining data in the TCP stream, ssldump can crash.

Workaround:
None.

Fix:
ssldump now successfully decrypt a capture, so ssldump no longer crashes.

644851-2 : Websockets closes connection on receiving a close frame from one of the peers

Component: Local Traffic Manager

Symptoms:
Websocket connection should be closed once an endpoint has both sent and received a Close control frame. BIG-IP closes connection on receiving a close frame from peer and does not wait for close frame from other endpoint. This results in data sent in the other direction to be dropped.

Conditions:
Websocket and HTTP profile are attached to the virtual.

Impact:
One endpoint sends a Websocket Close control frame. Other endpoint continues sending data which is dropped by BIG-IP.

Fix:
Half-close of connection will be triggered instead of closing the connection entirely.

---

644822-2 : FastL4 virtual server with enabled loose-init option works differently with/without AFM provisioned

Solution Article: K19245372

Component: Advanced Firewall Manager

Symptoms:
If AFM provisioned, a FastL4 virtual server with enabled loose-init option drops all RST packets that do not relate to any existing flows.

This behavior does not match the BIG-IP behavior when AFM is not provisioned.

Conditions:
AFM provisioned.
-- FastL4 virtual server.
-- Loose-init option enabled.

Impact:
RST packets that do not relate to any existing flows are dropped, while they should not be dropped if the loose-init option enabled.

Workaround:
No workaround.

Fix:
Fixed, so FastL4 virtual servers with enabled loose-init option will forward any RST packets.

644565-1 : MRF Message metadata lost when routing message to a connection on a different TMM

Component: Service Provider

Symptoms:
The system might choose to create a new outgoing connection when there is an available exiting connection that can be used.

Conditions:
When a message is forwarded to another TMM for delivery, an internal state might be lost.

Impact:
Messages should be delivered correctly as the metadata is lost after routing. There might be an impact if routing is retried and the ignore-peer-port setting is lost. This might cause a new connection to be created when an available existing connection exists.

Workaround:
None.

Fix:
The system now ensures that the ignore-peer-port flag is preserved when forwarding a message to a connection on another TMM.

644490-1 : Finisar 100G LR4 values need to be revised in f5optics

Component: TMOS

Symptoms:
The original tuning values for the Finisar 100G LR4 optics don't support module tuning. You might see FCS errors.

Conditions:
FCS errors can be observed with the shipping Finisar 100G LR4 tuning values.

Impact:
Occasional packet loss at the 100G physical layer.

Workaround:
Use 100G SR4 optics modules on the link if possible.

Fix:
FCS errors no longer occur using the latest Finisar 100G LR4 tuning values.

For information on installing and using the latest f5optics package (build 48.0 or later) that contains these tuning values, see F5 Platforms: Accessories (https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/f5-plat-accessories.html).

644489-1 : Unencrypted iSession connection established even though data-encrypt configured in profile

Solution Article: K14899014

Component: Wan Optimization Manager

Symptoms:
iSession connections may be intermittently established as unencrypted even though they are configured to be secure.

Conditions:
Either of two scenarios can result in an unencrypted iSession connection being established:
    1) An error occurs during dynamic server-ssl profile replacement.
    2) Both the WOM local-endpoint and destination WOM remote-endpoint lack server-ssl profiles.

In both cases the virtual server must have a server-side iSession profile with data-encrypt enabled and the remote virtual must have a client-ssl profile with allow-non-ssl enabled.

Impact:
An unencrypted iSession connection may be established which is inconsistent with configuring data-encrypt as enabled in the sever-side iSession profile.

Workaround:
Configure the client-ssl profile with allow-non-ssl disabled (the default value) to reject non-SSL connections.

Fix:
The outgoing connection is aborted if the server-side iSession profile is configured with data-encrypt enabled and either of the two following scenarios occurs:
    1) The destination remote-endpoint and the local-endpoint lack server-ssl profiles.
    2) An error occurs during dynamic server-ssl profile replacement.

sync_zones script now exits successfully at network failure.

---

644418-2 : Do not consider self-signed certificate in hash algorithm selection when Forward Proxy forges a certificate

Component: Local Traffic Manager

Symptoms:
SSL Forward Proxy signs a forged certificate with a hash algorithm. This selected hash algorithm is the weakest algorithm from the certificates in the server certificate chain including the self-signed certificate.
Many of the self-signed certificates use the SHA1 hash algorithm, which is not acceptable to many sites. The SSL handshake may be rejected.

Conditions:
This may occur when SSL Forward Proxy is in use.

Impact:
Forged certificate with SHA1 hash algorithm may be rejected during SSL handshake and the SSL handshake will then fail.

Workaround:
None.

Fix:
In this release, the system excludes self-signed certificates in hash algorithm selection (which is correct behavior). This may prevent forged certificate from using SHA1 hash algorithm

---

644404-1 : Extracting SSD from system leads to Emergency LCD alert★

Component: TMOS

Symptoms:
When an SSD in a dual-SSD system configuration is extracted, an emergency alert may be issued on the LCD. This does not match the actual severity (Warning) as reported in the LTM log.

Conditions:
Dual SSDs in any BIG-IP system where one has been selected for removal.

Impact:
LCD reports an Emergency-level alert, which does not match the actual Warning severity reported in the LTM log.

Workaround:
Clear the Emergency alert from the LCD.

Fix:
The classification for SSD removal has been changed to 'Warning' to match the LTM log level.

Solution Article: K27629542

Component: Local Traffic Manager

Symptoms:
An LTM policy using a rule that attempts to match based on a list of IP addresses may fail if more than one IP address is used.

Conditions:
LTM policy rule with a 'tcp match address' statement that attempts to match against more than one IP address.

Impact:
The action configured with the match may not be taken.

Workaround:
Use one of the following workarounds:
- Use a subnet instead of single IP addresses.
- Use a datagroup with the list of IP addresses to match.
* Datagroup option available beginning in v13.0.0.

Fix:
The BIG-IP system now correctly matches several IP addresses in LTM policies.

643631 : Serverside connections on virtual servers using VDI may become zombies.

Solution Article: K70938130

Component: Local Traffic Manager

Symptoms:
Listing connections with "tmsh show sys connection all-properties" (please be cautious executing this command as it could have performance impact) will show connections with only a server side whose age is greater than the configured idle timeout. As more zombie connections accumulate, the BIG-IP may run out of memory.

Conditions:
APM provisioned and VDI (Virtual Desktop Infrastructure) is configured on the affected virtual.

Impact:
Zombie connections consume memory that cannot be reclaimed. Potential out-of-memory condition.

Workaround:
None.

643602-2 : 'Select All' checkbox selects items on hidden pages

Component: Fraud Protection Services

Symptoms:
In FPS GUI, clicking 'Select All' when the list contains more than 10 items, selects all items and not just the items on the current page, as expected.

Conditions:
-- FPS provisioned and licensed.
-- Check 'Select All' and click Delete on a list page containing enough items to span more than one page, for example:

On the Security :: Fraud Protection Service :: Anti-Fraud Profile :: Mobile Security :: Man in the Middle Detection page, add 20 domains. This creates two pages of domains on the list page. When you then check 'Select all' and click Delete, all 20 domains are deleted instead of the expected 10 visible on the page.

Impact:
Unexpected behavior: items are deleted from pages that are not visible.

Workaround:
Check one or more items individually for deletion.

Fix:
Clicking the 'Select All' checkbox now selects all items on the currently visible page.

643547-1 : APMD initialization may fail when large number of access policy agents are configured in access policies installed on BIG-IP

Solution Article: K43036745

Component: Access Policy Manager

Symptoms:
Requests to /my.policy are not getting HTTP responses.

Log file '/var/log/apm' contains large number of error messages about failed XML data creation:

err apmd[5076]: 01490207:3: SAML Agent XML thread specific data creation error: ERR_FAIL.

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

-- Your BIG-IP APM system is configured with a large number of access policy agents.
-- You are performing an operation that requires the apmd process to start.
-- For example, your BIG-IP APM system is reloaded, you install a new image, or you manually restart the apmd process.

Impact:
APMD will not able to process any requests.

Workaround:
For some configurations and platforms, you can use the following steps to recover:

- Remove all unused access policies (if applicable).
- Restart apmd.

Fix:
Now APMD initialization will no longer fail at XML initialization when a large number of access policies/agents are present in the configuration.

643404-2 : 'tmsh system software status' does not display properly in a specific cc-mode situation★

Solution Article: K30014507

Component: TMOS

Symptoms:
If software image verification is enabled, the system must first verify a software archive with a cryptographic signature file before using it. If that file is not available, the software change will (intentionally) not proceed. It is also intended that 'tmsh system software status' will explain the condition. But instead, it shows 'failed (reason unknown)'.

Conditions:
Trying to initiate a software change, but there is no signature file available that corresponds to the selected software archive if any of the following is also true:
-- The system is in Common Criteria mode (db var Security.CommonCriteria).
-- The system is in FIPS compliance mode (db var security.fips140.compliance).
-- Signature checking is manually enabled (db var LiveInstall.CheckSig).

Impact:
It is difficult to ascertain why the software change cannot be made.

Workaround:
The installation logs a more detailed explanation for the failure. In the case of Common Criteria mode, it is essential to have the signature file in the same images directory as the .iso image you intend to install.

To do so, copy the .sig file from the F5 Downloads site to the image location, and try the installation again.

Fix:
The 'tmsh show system software status' now displays the relevant issue, for example:
failed (No signature verification possible for image /shared/images/BIG-IP-12.1.2.0.0.249.iso).

Although you must still download the .sig file from F5 Downloads, it's clear what the failure is and what to do next.

Solution Article: K45444280

Component: Local Traffic Manager

Symptoms:
When mcpd (re)starts on a secondary slot, part of the initialization process triggers the delete of any netHSM keys on the SafeNet HSM.

Conditions:
This occurs on a chassis that is configured to use a SafeNet netHSM.

Impact:
The key is removed from the HSM and must be reimported to the HSM from a backup, if it exists.

Workaround:
When rebooting a secondary blade, temporarily remove the BIG-IP from the network it uses to connect to the SafeNet HSM. Once the BIG-IP is Active, it is safe to reconnect it to the network.

Fix:
The BIG-IP no longer deletes keys from the Safenet HSM when the key is deleted from the BIG-IP system. Now, you must manually delete keys using fipskey.nethsm or 'cmu delete'.

Important! Delete operations cannot be undone. Before deleting keys on the HSM using one of these commands, make sure that the key is not used by any BIG-IP, because the key deletion on the HSM is irreversible.

Behavior Change:
Beginning with this release, the BIG-IP system will not delete a key from the SafeNet HSM when you delete the corresponding key on the BIG-IP system: You must manually delete the key on the HSM using either fipskey.nethsm or 'cmu delete'.

Important! Delete operations cannot be undone. Before deleting keys on the HSM using one of these commands, make sure that the key is not used by any BIG-IP, because the key deletion on the HSM is irreversible.

643143-2 : ARP and NDP packets should be QoS/DSCP marked on egress

Component: Local Traffic Manager

Symptoms:
There is currently no way to prioritize ARP/NDP traffic on BIG-IP or configure QoS on TMM-originated ARP/NDP packets.

Conditions:
ARP and/or NDP is in use.

Impact:
When the BIG-IP system's CPU is saturated, there is a possibility that ARP and NDP packets might be dropped.

Workaround:
N/A

Fix:
You can now configure QoS on TMM-originated ARP/NDP packets.

To have ARP and NDP packets be treated with high priority internally within the BIG-IP system, set the following database keys to 'high':
-- arp.priority
-- ipv6.nbr.priority

To explicitly assign the 802.1p/q priority (QoS bits), set the following database keys:
-- arp.vlanpriority
-- ipv6.nbr.vlanpriority

Note: The 802.1q/p QoS priority applies to queries that originate on the BIG-IP system. Replies generated by BIG-IP will preserve the QoS value received in the request.

These variables are set with the following commands:

tmsh modify sys db arp.priority value (normal|high)
tmsh modify sys db arp.vlanpriority value [-1-7]
tmsh modify sys db ipv6.nbr.priority value (normal|high)
tmsh modify sys db ipv6.nbr.vlanpriority value [-1-7]

Behavior Change:
You can now configure QoS on TMM-originated ARP/NDP packets.

To have ARP and NDP packets be treated with high priority internally within the BIG-IP system, set the following database keys to 'high':
-- arp.priority
-- ipv6.nbr.priority

To explicitly assign the 802.1p/q priority (QoS bits), set the following database keys:
-- arp.vlanpriority
-- ipv6.nbr.vlanpriority

Note: The 802.1q/p QoS priority applies to queries that originate on the BIG-IP system. Replies generated by BIG-IP will preserve the QoS value received in the request.

These variables are set with the following commands:

tmsh modify sys db arp.priority value (normal|high)
tmsh modify sys db arp.vlanpriority value [-1-7]
tmsh modify sys db ipv6.nbr.priority value (normal|high)
tmsh modify sys db ipv6.nbr.vlanpriority value [-1-7]

643121-1 : Failed installation volumes cannot be deleted in the GUI.

Component: TMOS

Symptoms:
Failed installation volumes aren't displayed under Disk Management and, therefore, cannot be deleted.

Conditions:
Have a failed installation volume.

Impact:
Cannot use the GUI to delete

Workaround:
Use tmsh to delete failed installation volumes using a command similar to the following:
tmsh delete /sys software volume <HDx.y>.

For example, to delete software volume HD1.0, use the following command:
tmsh delete /sys software volume HD1.0.

Fix:
Failed installation volumes can now be deleted in the GUI.

---

643054-2 : ARP and NDP packets should be CoS marked by the swtich on ingress

Component: Local Traffic Manager

Symptoms:
When ARP and NDP requests are dropped, ARP caches can time out, and peer nodes may fail to resolve the BIG-IP system's self-IP addresses or virtual servers.

Conditions:
TMM0 is saturated and dropping packets.

Impact:
ARP requests can be dropped, and peer devices, such as routers and monitored devices, can fail to resolve the BIG-IP system's address.

Workaround:
None.

Fix:
You can now use db variables to control internal traffic priority for ingress ARP/NDP packets in the switch.

-- arp.priority : high/normal (default)
-- ipv6.nbr.priority : high/normal (default)

The 'normal' value is the default.

-- Setting arp.priority to high raises ARP packet priority.
-- Setting ipv6.nbr.priority to high raises NDP packet priority.

Behavior Change:
You can now use db variables to raise the internal traffic priority for ingress ARP/NDP packets in switch.

arp.priority : high/normal(default)
ipv6.nbr.priority : high/normal(default)

Setting arp.priority to high raises ARP packet priority.
Setting ipv6.nbr.priority to high raises NDP packet priority.

Symptoms:
DAGv2 is a new DAG type and is designed to run on new platforms, including i5600, i5800, i7600, i7800, i10600, i10800 platforms. DAGv2 was not ready when these platforms were first released. DAGv2 is enabled on these platforms in v12.1.3.

Conditions:
i5600, i5800, i7600, i7800, i10600, i10800 platforms.

Impact:
No functional impact. This is simply an announcement of a change in the DAG version.

Workaround:
None.

Fix:

642983-1 : Update to max message size limit doesn't work sometimes

Solution Article: K94534313

Component: Device Management

Symptoms:
There is a cap on all REST request/response message size. By default it is set to 32 MB, and you can modify it to higher limit using /mgmt/shared/server/messaging/settings/8100 REST endpoint. But the REST framework may not apply this change.

When this occurs, you will see 501 Bad Gateway error from Apache and error message link "java.lang.IllegalArgumentException: 47177925 is more than 33554432" in restjavad log (/var/log/restjavad.0.log).

Conditions:
This can occur when requesting or receiving more than 32 MB of data via iControl REST.

Impact:
REST framework applies message body limit only on incoming request and response. If incoming request results in requests to iControl REST or restnoded, the same settings (message body limit) are not applied.

Workaround:
None.

Fix:
Messaging settings are applied on requests/responses, rather than on RestServer as forwarded outgoing requests/responses will not have server instance attached to request.

Conditions:
-- Dynamic routing configured.
-- Non-default partition name or VLAN names greater than 15 characters.

Impact:
Dynamic routing does not function. This may include monitors not functioning properly and marking pool members down incorrectly.

Workaround:
Shorten VLAN, VLAN group, or tunnel name, or move the interface into the Common partition.

Fix:
tmrouted no longer restarts when using long VLAN, VLAN group, or tunnel names in a non-default partition.

Solution Article: K15329152

Component: Application Security Manager

Symptoms:
Signatures that have not passed the staging period are shown when the filter is set to only show those that are ready to be enforced.

Conditions:
Signatures exist on a policy that have not passed their staging period and have no learning suggestions for them.

Impact:
Incorrect results are shown as a result of the filter.

Workaround:
The result should be inspected to see if the staging period has passed for each individual signature.

Fix:
The "Ready to be Enforced" filter works correctly.

642723-3 : Western Digital WD1600YS-01SHB1 hard drives not recognized by pendsect

Component: TMOS

Symptoms:
In version 11.4.0, when pendsect was introduced, the Western Digital WD1600YS-01SHB1 hard drive was not supported. This drive was used in very early shipments of the 1600/3600 products.

If you are running 11.4.0 and have a WD1600YS-01SHB1, you might see the following errors in /var/log/ltm:

-- notice pendsect[1662]: skipping drive -- Model: WDC WD1600YS-01SHB1
-- notice pendsect[1662]: No known drives detected for pending sector check. Exiting

Conditions:
-- Running 11.4.0.
-- Using WD1600YS-01SHB1 hard drives.

Impact:
The only impact is a pendsect notice in /var/log/ltm. The hard drive operates as expected.

Workaround:
There is no mitigation or workaround for this issue.

Fix:
The WD1600YS-01SHB1 hard drive was added to the supported list of hard drives in versions 11.5.x, 11.6.x, and 12.1.3.

642703-2 : Formatting installation using software v12.1.2 or v13.0.0 fails for i5000, i7000, i10000, i11000, i12000 platforms.★

Component: TMOS

Symptoms:
Installation from external media (PXE or USB) fails with error:

error: status 768 returned by command: /sbin/lvcreate -L -4719088K -n dat.share vg-db-cpmirror
info: >++++ result:

error: MultiVolume_add cpmirror.dat.share failed.

Conditions:
-- i5000, i7000, i10000, i11000, and i12000 platforms.
-- Installation from external media (PXE or USB).
-- Running software v12.1.2 or v13.0.0.

Impact:
System is non-functional. It will not work at all, until an 'installation from external media' is performed. There is no software on the system because the operation failed during the early stages of a formatting installation.

Workaround:
Use an earlier version for the formatting installation, such as 12.1.1, and then upgrade to the target version.

Fix:
The error no longer occurs; the formatting installation succeeds.

642400-2 : Path MTU discovery occasionally fails

Component: Local Traffic Manager

Symptoms:
Connections using a TCP profile that receive an ICMP needsfrag message may incorrectly ignore the message. This may cause Path MTU discovery to fail.

Conditions:
TCP profile assigned to VIP. Smaller MTU on data path than on TCP endpoints.

Impact:
The connection may stall as large TCP segments are continually retransmitted.

Workaround:
Configure the MSS in the TCP profile to match the lowest MSS. Use or disable Path MTU discovery with the tm.pathmtudiscovery database key.

Fix:
Path MTU discovery functions correctly with the TCP profile.

---

642330-2 : 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.

642314-2 : CNAME ending with dot in pool causes validation problems after upgrade from 11.x to 12.x or v13.x★

Solution Article: K24276198

Component: TMOS

Symptoms:
gtm config load failure after upgrade from v11.x to v12.x or v13.x.

Conditions:
Create GTM pool with canonical-name ending with dot - for example "cname-with-dot.com." in v11.x and then upgrade to v12.x or v13.x.

Impact:
gtm config load failure after upgrade.

Workaround:
Remove trailing dots or set "Domain Validation" to "none".

Fix:
Upgrading from 11.x to 12.x or 13.x with GTM Pool with canonical-name removes trailing FQDN dot.

642284 : Closing a PCP connection while an asynchronous mapping request is in progress may result in memory corruption.

Component: Carrier-Grade NAT

Symptoms:
Memory corruption caused by closing a PCP connection while requests are being processed.

Conditions:
This can occur when a PCP client sends multiple requests and closes before receiving the replies. When the client OS receives a reply it will send an ICMP destination unreachable message which causes the BIG-IP to close the PCP connection. If the PCP connection is closed while a request is being processed, memory corruption may occur when the request completes.

Impact:
When memory corruption occurs, TMM may crash or assert. Traffic disrupted while tmm restarts.

Fix:
Closing the PCP connection will not cause memory corruption.

642221-2 : Incorrect entity is used when exporting TCP analytics from GUI

Component: Application Visibility and Reporting

Symptoms:
When exporting statistics from the TCP Analytics page, the resulted data is for the default "view by" entity rather than the one that's actually selected

Conditions:
This occurs in Statistics :: Analytics : TCP, when you are viewing any dimension other than the default, and clicking Export.

Impact:
Incorrect data is being exported.

Workaround:
Use tmsh.

Fix:
The correct entity is now used when exporting TCP analytics from GUI, so the correct data is being exported.

641512-4 : 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.

641491-2 : TMM core while running iRule LB::status pool poolname member ip port

Solution Article: K37551222

Component: Local Traffic Manager

Symptoms:
An iRule response to a DNS request may trigger the Traffic Management Microkernel (TMM) to produce a core file and restart. As a result of this issue, you may encounter one or more of the following symptoms:

-- The BIG-IP system may temporarily fail to process traffic as it recovers from the TMM restart, and devices configured as an HA pair may fail over.
-- The BIG-IP system generates a TMM core file to the /shared/core directory.

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

-- Your BIG-IP DNS system is configured with a wide IP that utilizes an iRule.
-- The iRule uses the DNS_REQUEST event command LB::status to check a pool member status.
-- The iRule pool address and port are separated by white space.

Example iRule syntax:

gtm rule pool_member_selection {
    when DNS_REQUEST {
        LB::status pool pool-one member 10.0.0.10 80
    }
}

Impact:
Traffic disrupted while tmm restarts.

Workaround:
Use format 'ip:port' or vsname instead of 'ip port. Following are two examples:
1.
gtm rule rule_crash_test {
    when DNS_REQUEST {
        LB::status pool pool-one member 10.2.108.100:80
    }
}

2.
gtm rule rule_crash_test {
    when DNS_REQUEST {
        LB::status pool pool-one member pool_vs_name
    }
}

Fix:
An iRule response to a DNS request no longer triggers TMM to produce a core file and restart.

641482-2 : Subscriber remains in delete pending state until CCR-t ack has success as result code is received

Component: Policy Enforcement Manager

Symptoms:
BIG-IP subscriber session will remain in delete pending (stale) state if the Result-code received Acknowledgement from Gx or Gy and is marked as Failure for CCR-T request.

Conditions:
The stale session happens, during subscriber termination and if any CCR-T request for Gx or Gy receives an acknowledgement with non-SUCCESS in Result-code AVP

Impact:
The subscriber session in BIG-IP will stay in delete pending state (stale)

Workaround:
A tmm restart will cleanup all the stale sessions

Fix:
Fix will cleanup the session if a CCR-T acknowledgement is received irrespective of the Result-code AVP

641390-5 : Backslash removal in LTM monitors after upgrade

Solution Article: K00216423

Component: TMOS

Symptoms:
After upgrading, BIG-IP fails to load the configuration and reports that a monitor failed to load.

Conditions:
-- Specific backslash escaping in LTM monitors.
-- Upgrading from 11.5.x, 11.6.0, 11.6.1, 11.6.2, or 11.6.3 to 12.0.0, 12.1.0, 12.1.1, 12.1.2, or 13.0.0.

Note: This issue is specific to LTM monitors. It does not occur in BIG-IP DNS/GTM monitors.

For example, to have two backslashes in the value, you specify three backslashes. The first backslash is the 'escape' character.

ltm monitor https /Common/my_https {
    adaptive disabled
    cipherlist DEFAULT:+SHA:+3DES:+kEDH
    compatibility enabled
    defaults-from /Common/https
    destination *:*
    interval 5
    ip-dscp 0
    recv "Test string"
    recv-disable \\\"Test\\\"me\\\" <-- pertinent string value (can be in recv, send or username attributes too).
    send Test
    time-until-up 0
    timeout 16
    username test\\\"me
}

Impact:
The monitor fails to load.

Workaround:
Manually correct the string to be the way it was before upgrade, then the configuration will load.

Fix:
Upgrade no longer results in incorrectly removing backslashes for some LTM monitor attributes.

640903-1 : Inbound WideIP list page on Link Controller takes a long time to load when displaying 50+ records per screen

Component: Global Traffic Manager (DNS)

Symptoms:
Extremely long page load on Link Controller Inbound Wide IP list page.

Conditions:
The preference settings "Records per screen" must be a high value. 50 or more will start causing the page to load very slowly.

Impact:
Extremely long page load time.

Workaround:
Prior to the fix, the workaround is to set the preference settings "Records per screen" to a low value. The default value of 10 is fine.

Fix:
The page can now load hundreds of records on a single screen under 3 seconds.

-------------------------

Conditions:
-- ASM provisioned.
-- Local request logging enabled.
-- Upgrade of a maintenance release, hotfix, or engineering hotfix.

Impact:
Upgrade fails.

Workaround:
Upgrade by the means of saving a UCS, performing a clean install and then loading the UCS.

In the manual save/load UCS process, the upgrade of the Request Log can be disabled, which will workaround the error and the UCS will load fine.

There are two options to disable the upgrade of the Request Log, when upgrading by the means of a UCS:
-------------------
1) Do not load a Request Log, when loading a UCS:
    # tmsh modify sys db ucs.asm.traffic_data.load value never

2) Do not save a Request Log, when saving a UCS:
    # tmsh modify sys db ucs.asm.traffic_data.save value disable
-------------------

Fix:
Roll-forward upgrade including traffic data now works correctly.

640636-3 : F5 Optics seen as unsupported instead of misconfigured when inserted into wrong port on B4450 Blade

Component: TMOS

Symptoms:
Inserting a 40G optic into a 100G port, or inserting a 100G optic into a 40G shows the optic as "Unsuported Optic". That is not correct, it may be a supported optic, just inserted in the wrong port.

Conditions:
B4450 Blades with 100G or 40G optics inserted in a port that does not support that speed optic.

Impact:
The user may be confused on why the optic is not working, the error message is misleading when the optic is inserted in the wrong port.

Workaround:
If the optic shows up in "tmsh list net interface" as "Unsuported Optic" remove the optic and verify that the optic speed matches the port.

Fix:
The "tmsh list net interface" will now show:
 
module-description "F5 Qualified Optic in invalid port"

And the LCD warning message will show:
Optic OPT-XXXX not valid in Interface <InterfaceNumber>.

640376-3 : STPD leaks memory on 2000/4000/i2000/i4000 series

Component: Local Traffic Manager

Symptoms:
STPD process on any 2000/4000/i2000/i4000 series platform that sends BPDUs will grow in physical memory usage indefinitely so long as its role in the tree results in sending BPDU packets. The memory usage will be faster for each interface that is sending BPDUs.

Conditions:
Spanning tree is enabled on any 2000/4000/i2000/i4000 series platform and the device has a role in the tree that results in sending BPDUs on one or more interfaces. Memory can be seen to increase when tracking with Linux top commands.

ex. top -b -n 1 | grep stpd

The 5th and 6th columns 'VIRT' and 'RES' slowly increase over time, indicating the memory leak.

Impact:
Memory leak resulting in indefinite consumption of available physical memory over time.

Workaround:
While the memory leak itself cannot be mitigated without a hotfix, the problem can be avoided if the tree can be configured in such a way that the defect affected platforms don't generate BPDUs. This can be done by choosing a root such that the defect affected platforms will have its interfaces to be in blocking mode, or if possible, to be in passthrough mode.

Fix:
BPDU process source code fixed to release memory allocated for each BPDU packet created and sent.

638997-2 : Reboot required after disk size modification in a running BIG-IP VE instance.

Component: TMOS

Symptoms:
- BIG-IP VE supports disk size modification during the lifetime of a running instance to expand or reduce the disk size that was allocated at the time of deployment.

- A reboot is required after any such modification in the disk size for the changes to take effect. In previous versions, the reboot happened automatically but an affected BIG-IP VE will not have the reboot happening automatically.

- Due to the lack of reboot, changes in disk size do not take effect on the BIG-IP system.

Conditions:
Modifying disk size in a running BIG-IP VE instance.

Impact:
Changes in the disk size do not take effect till BIG-IP system is rebooted.

Workaround:
Manually reboot the running BIG-IP VE instance after making changes in disk size.

Fix:
Reboot required after disk size modification in a BIG-IP VE instance.

---

638935-3 : 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.

638715-3 : Multiple Diameter monitors to same server ip/port may race on PID file

Solution Article: K77010072

Component: Local Traffic Manager

Symptoms:
Two 'Diameter_monitor' instances probing the same server (IP/port) from different pools may interfere with each other, causing one of the monitor instances to fail. This is caused by a possible race in creating a PID file for this 'Diameter_monitor' configuration.

Conditions:
Configuration with multiple Diameter monitors probing the same server IP/port.

Impact:
One Diameter monitor may fail, while the other Diameter monitor to the same server IP/port succeeds. On subsequent probe-retry, the failed monitor may now succeed.

Workaround:
A possible work-around is to establish different monitor periods for the two pools (such as 28 seconds and 31 seconds), so a simultaneous probe-collision will fail one monitor once, which upon retry will succeed (as three monitor failures are required for a virtual server to be marked down).

Fix:
The fix includes the monitor-template name in the generation of the PID file, which ensures multiple Diameter monitor instances probing the same server (IP/port) do not interfere with each other.

636520-3 : Detail missing from power supply 'Bad' status log messages

Solution Article: K88813435

Component: TMOS

Symptoms:
When an internal hardware sensor alert is received indicating a 'Bad' power supply status, no detail is included which indicates which characteristic of the power supply's state is resulting in a 'Bad' overall status for the power supply.
In this scenario, the message logged at default logging level contains information similar to the following:
... crit chmand[...]: 012a0013:2: Blade 0 hardware sensor critical alarm: Power Supply 2 GPIO status(SPAFFIV03G): Bad

Conditions:
This occurs when the system posts an internal hardware sensor alert.

Impact:
Unable to diagnose cause of 'Bad' power supply status at default logging level to determine whether the probable cause is due to a power supply hardware fault or a possible external power source issue.

Workaround:
If power supply errors continue to be logged:

1. Set the libhal logging level to 'Debug':
tmsh mod sys db log.libhal.level { value "Debug" }

2. Let the system run in this configuration for at least a few minutes to collect a number of chmand error logs, such as:
... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x3 pin:0x2 action:0xd
... debug chmand[...]: 012a0007:7: Received Sensor Alert: sensor id 0x16f slot 0xff
... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x1 pin:0x2 action:0x3.

3. Set the libhal logging level back to 'Notice':
tmsh mod sys db log.libhal.level { value "Notice" }

4. Take a qkview or an archive of /var/log/ltm, and engage F5 Professional Services for further analysis.

Fix:
When an internal hardware sensor alert is received indicating a 'Bad' power supply status, additional detail is now logged to help identify the cause of the 'Bad' overall status for the power supply.

636397-1 : bd cores when persistent storage configuration and under some memory conditions.

Component: Application Security Manager

Symptoms:
bd cores. Log signature in /var/log/bd looks similar to the following:

BD_MISC|ERR |Jan 02 14:24:06.422|27867|io_manager_init.c:0395|internal_keep_alive: BD shrinking...,going down - BD will be right back.
ptr BD_MISC|CRIT |Jan 02 14:24:06.422|27867|signals.c:0073|Received SIGSEGV - Core Dumping.

Conditions:
There is persistent storage configuration. There is high memory usage.

Impact:
bd crash. Traffic resets and/or failover

Workaround:
None.

Fix:
This release fixes a bd crash due to specific memory conditions and persistent storage.

636370 : Application Layer Encryption AJAX support

Component: Fraud Protection Services

Symptoms:
WebSafe doesn't support parameters encryption in Single Page Applications (using AJAX)

Conditions:
Application uses AJAX for sending parameters to web server

Impact:
Encryption won't work for Single Page Applications

Workaround:
N/A

Fix:
Adding AJAX encryption support (full payload encryption)

for 12.1.2-hf, enabling this feature requires:

tmsh modify sys db antifraud.internalconfig.string1 value <AJAX-HEADER-NAME>

AJAX-HEADER-NAME existence will enable AJAX support for current request and its value may contain the username used in current request (if configured and exists)

Note that activating AJAX support in releases > 12.1.2-hf is done differently (configured in profile, not in db)

636254-2 : Cannot reinitiate a sync on a target device when sync is completed

Component: Access Policy Manager

Symptoms:
After a policy sync is successful, re-initating a sync fails with the following error:
"PolicySyncMgr: Sync already in progress for policy xxx"

Conditions:
This occurs rarely when performing a sync after a successful sync.

Impact:
You cannot re-sync a policy. This is a rare occurrence, and after waiting a small amount of time sync should start working again.

Fix:
Now APM Policy Sync no longer hangs in rare cases with the message: "PolicySyncMgr: Sync already in progress for policy xxx"

636149-3 : Multiple monitor response codes to single monitor probe failure

Component: Local Traffic Manager

Symptoms:
A monitor probe failure to a monitor (such as HTTP) will be logged to '/var/log/ltm' when the probed resource is unavailable. In some cases for a probe resulting in an 'Unable to connect' error, multiple log entries will be made, with the *last* log entry being the error that triggered the log entry. The other monitor entries made during this event are not specifically relevant, as they are "stale" and due to previous monitor probe behavior that was previously logged.

This is due to an error where the 'Could not connect' event appends a previous error message, rather than overwriting a possibly-present previous error message.

Conditions:
A monitor probe to a monitor is attempted (such as over HTTP), resulting in an "Unable to connect" failure; and where that specific monitor previously reported an error (which is now appended).

Impact:
No system behavior is affected, but multiple log entries are made. The *final* log entry of "Could not connect" or "Unable to connect" is relevant, while the possible multiple log entries immediately above are "stale" and not relevant (as they are due to a previous issue that was previously successfully logged).

Workaround:
For an external monitor that generates a 'Could not connect' or 'Unable to connect' error, user should consider only the last-line for the '/var/log/ltm' log entry, and ignore possibly-present log entries associated with that specific monitor that might be appear immediately above the 'Could not connect' line.

Fix:
The code fix is to "clear" previous monitor-log errors when reporting a 'Could not connect' error, rather than appending a previous error that might be present.
