[El-errata] New updates available via Ksplice (ELBA-2016-3511)

[Errata Announcements for Oracle Linux]

Synopsis: ELBA-2016-3511 can now be patched using Ksplice

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, ELBA-2016-3511.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on EL 7 install these
updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Possible deadlock in mlx4_vnic when flush is not needed.

Mellanox Technologies VNIC driver has a possible deadlock when a flush
was not needed during restarting of a discovery.


* Incorrect access control check in keyctl get_persistent.

Non-privileged callers to keyctl_get_persistent would receive an EPERM
error when requesting access their own persistent keyctl cache.


* Deadlock when syncing frozen filesystem.

Broken lock ordering could cause a deadlock when sync attempts to drop
unused inodes on a frozen filesystem.
