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

Patch ID: 5.0.41.100

* 2708637 (Tracking ID: 2708619)

SYMPTOM:
If you set the scsi3_disk_policy attribute to dmp, you cannot enable the Veritas
fencing module (VxFEN).

DESCRIPTION:
When you set the scsi3_disk_policy attribute to dmp, the VxFEN module tries to
use the dmp device path to access the coordination disks. The dmp device path
refers to a disk partition. A recent kernel security fix prohibits the SCSI
ioctl system call to disk partitions. As a result the VxFEN configuration fails.
The recent kernel security fix that prohibits system calls to disk partitions is:
752375 - CVE-2011-4127 kernel: possible privilege escalation via SG_IO ioctl

RESOLUTION:
Symantec has updated the VxFEN source code to pick up the dmp device path that
contains the full disk name instead of a partition/slice.
