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

Patch ID: VRTSvxfs-7.1.0.4100

* 3964461 (Tracking ID: 3951752)

SYMPTOM:
VxFS support for RHEL6.10 and RHEL/SUSE retpoline kernels

DESCRIPTION:
The RHEL6.10 is new release and it has Retpoline kernel. Also
redhat/suse released retpoline kernel for older RHEL/SUSE releases. The VxFS module 
should recompile with retpoline aware GCC to support retpoline kernel.

RESOLUTION:
Compiled VxFS with retpoline GCC.

Patch ID: VRTSvxvm-7.1.0.400

* 3964753 (Tracking ID: 3951290)

SYMPTOM:
Retpoline support for VxVM on RHEL6.10 and RHEL6.x retpoline
kernels

DESCRIPTION:
The RHEL6.10 is new release and it has Retpoline kernel. Also
redhat released retpoline kernel for older RHEL6.x releases. The VxVM module 
should be recompiled with retpoline aware GCC to support retpoline
kernel.

RESOLUTION:
Compiled VxVM with retpoline GCC.

* 3970407 (Tracking ID: 3970406)

SYMPTOM:
While CVM testing below error is observed :
[root@vmr720-34-vm9 ~]# vxclustadm nidmap
VxVM vxclustadm ERROR V-5-1-9675 Error doing ioctl: clusterinfo

DESCRIPTION:
The error is coming because the command structure which is sent to the underlying IOCTL has not been initialized which leads to garbage value in the IOCTL argument and leads to failure while allocating the memory for IOCTL argument.

RESOLUTION:
the command structure which is sent to the underlying IOCTL has been initialized .
Without Fix:

[root@vmr720-34-vm9 ~]# vxclustadm nidmap
VxVM vxclustadm ERROR V-5-1-9675 Error doing ioctl: clusterinfo

With Fix:

[root@vmr720-34-vm9 ~]# /root/vxclustadm nidmap

* 3964895 (Tracking ID: 3965469)

SYMPTOM:
lsmod is not showing the required APM modules loaded.

DESCRIPTION:
For supporting RHEL6.10 update, dmp module is recompiled with latest RHEL6.10 kernel
version. During post install of the package the APM modules fails to load due to
mismatch in dmp and  additional APM module kernel version.

RESOLUTION:
ASLAPM package is recompiled with RHEL6.10 kernel.

Patch ID: VRTSdbac-7.1.0.400

* 3964926 (Tracking ID: 3951435)

SYMPTOM:
RHEL6.x RETPOLINE kernels and RHEL 6.10 are not supported

DESCRIPTION:
Red Hat has released RHEL 6.10 which has RETPOLINE kernel, and also released RETPOLINE kernels for older RHEL6.x Updates. Veritas Cluster Server kernel modules need to be recompiled with RETPOLINE aware GCC to support RETPOLINE kernel.

RESOLUTION:
Support for RHEL 6.10 and RETPOLINE kernels on RHEL6.x kernels is now introduced.

Patch ID: VRTSamf-7.1.0.300

* 3964927 (Tracking ID: 3951435)

SYMPTOM:
RHEL6.x RETPOLINE kernels and RHEL 6.10 are not supported

DESCRIPTION:
Red Hat has released RHEL 6.10 which has RETPOLINE kernel, and also released RETPOLINE kernels for older RHEL6.x Updates. Veritas Cluster Server kernel modules need to be recompiled with RETPOLINE aware GCC to support RETPOLINE kernel.

RESOLUTION:
Support for RHEL 6.10 and RETPOLINE kernels on RHEL6.x kernels is now introduced.

Patch ID: VRTSvxfen-7.1.0.600

* 3964928 (Tracking ID: 3951435)

SYMPTOM:
RHEL6.x RETPOLINE kernels and RHEL 6.10 are not supported

DESCRIPTION:
Red Hat has released RHEL 6.10 which has RETPOLINE kernel, and also released RETPOLINE kernels for older RHEL6.x Updates. Veritas Cluster Server kernel modules need to be recompiled with RETPOLINE aware GCC to support RETPOLINE kernel.

RESOLUTION:
Support for RHEL 6.10 and RETPOLINE kernels on RHEL6.x kernels is now introduced.

* 3879189 (Tracking ID: 3878333)

SYMPTOM:
With I/O fencing in SCSI-3 mode, if you enable the auto-refresh feature on the 
CoordPoint agent, then I/O fencing fails to automatically refresh registrations 
on the coordination points. This results in vxfen group to remain in faulted 
state.

DESCRIPTION:
Even to refresh registration on coordination disks, the vxfenswap script 
expects inputs about coordination disk groups from the CoordPoint agent. The 
CoordPoint agent does not provide this information to the vxfenswap script.
This causes the vxfenswap script to fail and the vxfen group remains faulted 
until it is manually cleared.

RESOLUTION:
The I/O fencing program is modified such that in SCSI3 mode fencing, the 
vxfenswap script does not explicitly require the coordination disk group 
information for refreshing registration keys on disks.

Patch ID: VRTSgab-7.1.0.600

* 3964929 (Tracking ID: 3951435)

SYMPTOM:
RHEL6.x RETPOLINE kernels and RHEL 6.10 are not supported

DESCRIPTION:
Red Hat has released RHEL 6.10 which has RETPOLINE kernel, and also released RETPOLINE kernels for older RHEL6.x Updates. Veritas Cluster Server kernel modules need to be recompiled with RETPOLINE aware GCC to support RETPOLINE kernel.

RESOLUTION:
Support for RHEL 6.10 and RETPOLINE kernels on RHEL6.x kernels is now introduced.

* 3893802 (Tracking ID: 3893801)

SYMPTOM:
In large clusters, a node join for a gab port gets stuck.

DESCRIPTION:
When a node joins a cluster, a few GAB directed messages might be
delivered in the incorrect order to the GAB clients. This incorrect 
message order is because of a bug in code where the messages are added to the
GAB delivery queue in incorrect order.

RESOLUTION:
The program is modified to ensure that during a node join scenario,
the GAB directed messages are inserted in the various GAB queues in the correct
order.

Patch ID: VRTSllt-7.1.0.800

* 3964930 (Tracking ID: 3951435)

SYMPTOM:
RHEL6.x RETPOLINE kernels and RHEL 6.10 are not supported

DESCRIPTION:
Red Hat has released RHEL 6.10 which has RETPOLINE kernel, and also released RETPOLINE kernels for older RHEL6.x Updates. Veritas Cluster Server kernel modules need to be recompiled with RETPOLINE aware GCC to support RETPOLINE kernel.

RESOLUTION:
Support for RHEL 6.10 and RETPOLINE kernels on RHEL6.x kernels is now introduced.

* 3918068 (Tracking ID: 3918061)

SYMPTOM:
Veritas Infoscale Availability does not support Red Hat Enterprise Linux 6 Update 9 
(RHEL6.9).

DESCRIPTION:
Veritas Infoscale Availability does not support RHEL versions later than RHEL6
Update 8.

RESOLUTION:
Veritas Infoscale Availability support for Red Hat Enterprise Linux 6 Update 9
(RHEL6.9) is now introduced.

* 3896880 (Tracking ID: 3896875)

SYMPTOM:
Veritas Infoscale Availability (VCS) does not support SUSE Linux Enterprise Server 
12 Service Pack 2 (SLES 12 SP2).

DESCRIPTION:
Veritas Infoscale Availability did not support SUSE Linux Enterprise Server
versions released after SLES 12 SP1.

RESOLUTION:
Veritas Infoscale Availability support for SUSE Linux Enterprise Server 12 SP2 is
now introduced.

* 3906299 (Tracking ID: 3905430)

SYMPTOM:
Application IO hangs in case of FSS with LLT over RDMA during heavy data transfer.

DESCRIPTION:
In case of FSS using LLT over RDMA, sometimes IO may hang because of race conditions in LLT 
code.

RESOLUTION:
LLT module is modified to fix the race conditions arising due to heavy load with multiple 
application threads.

Patch ID: VRTSgms-7.1.0.2100

* 3964464 (Tracking ID: 3951761)

SYMPTOM:
