Synopsis: RHBA-2012:1104-1 can now be patched using Ksplice
CVEs:
Systems running Red Hat Enterprise Linux 6 can now use Ksplice to
patch against the latest Red Hat Bug Fix Advisory, RHBA-2012:1104-1.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on RHEL 6 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
* 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.
SUPPORT
Ksplice support is available at ksplice-support_ww at oracle.com.
