SRPMS:

Users with Oracle Linux Premier Support can now use Ksplice to patch
against this Bug Fix Advisory.

We recommend that all users of  Oracle Linux 6 install these updates.

Users of Ksplice Uptrack can install these updates by running :

# /usr/sbin/uptrack-upgrade -y
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 additional action.

Description of changes:

* Unreliable futexes with read-only shared mappings.

Futex operations on read-only memory maps did not work correctly,
breaking workloads that had one or more reader processes performing the
FUTEX_WAIT operation on a futex within a read-only shared file mapping
and a writer process that had a writable mapping performing the
FUTEX_WAKE operation.
