DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following incidents:

Patch ID: VRTSllt-8.0.0.1500

* 4073695 (Tracking ID: 4072335)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 8 
Update 6(RHEL8.6).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL8 Update 5.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 8 Update 
6(RHEL8.6) is now introduced.

Patch ID: VRTSllt-8.0.0.1200

* 4066063 (Tracking ID: 4066062)

SYMPTOM:
Node panic

DESCRIPTION:
Node panic observed in llt udp multiport configuration with vx ioship stack.

RESOLUTION:
When llt receives an acknowledgement, it tries to free the packet and corresponding client frags blindly without checking the client status. If the client is unregistered, then the free functions of the frags will be invalid and hence should not be called.

* 4066667 (Tracking ID: 4040261)

SYMPTOM:
During LLT configuration, if set-verbose is set to 1 in /etc/llttab, an lltconfig core dump is observed.

DESCRIPTION:
Some log messages may have IDs like 00000. When such logs are encountered, it may lead to a core dump by the lltconfig process.

RESOLUTION:
VCS is updated to use appropriate message IDs for logs so that such issues do not occur.

Patch ID: VRTSllt-8.0.0.1100

* 4064783 (Tracking ID: 4053171)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 8 
Update 5(RHEL8.5).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL8 Update 4.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 8 Update 
5(RHEL8.5) is now introduced.

Patch ID: VRTSamf-8.0.0.1500

* 4072752 (Tracking ID: 4072335)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 8 
Update 6(RHEL8.6).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL8 Update 5.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 8 Update 
6(RHEL8.6) is now introduced.

Patch ID: VRTSamf-8.0.0.1100

* 4064788 (Tracking ID: 4053171)

SYMPTOM:

Update 5(RHEL8.5).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL8 Update 4.

RESOLUTION:

5(RHEL8.5) is now introduced.

Patch ID: VRTSvxfen-8.0.0.1500

* 4072717 (Tracking ID: 4072335)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 8 
Update 6(RHEL8.6).

DESCRIPTION:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 
versions later than RHEL8 Update 5.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 8 Update 
6(RHEL8.6) is now introduced.

Patch ID: VRTSvxfen-8.0.0.1200

* 3951882 (Tracking ID: 4004248)

SYMPTOM:
vxfend process segfaults and coredumped

DESCRIPTION:
During fencing race, sometimes vxfend crashes and generates core dump

RESOLUTION:
Vxfend internally uses fork and exec to execute sub tasks. The new child process was using same file descriptors for logging purpose. This simultaneous read of same file using single file descriptor was resulting incorrect read and hence the process crash and coredump. This fix creates new file descriptor for child process to fix the crash
