[Ksplice][EL6-Updates] New updates available via Ksplice (RHBA-2012:1104-1)

[Jamie Iles]

Synopsis: RHBA-2012:1104-1 can now be patched using Ksplice

Systems running Red Hat Enterprise Linux 6, CentOS 6, and Scientific
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, CentOS 6,
and Scientific Linux 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.
