RHBA-2013:1000 - Bug Fix Advisory

Topic

Updated selinux packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

The selinux-policy packages contain the rules that govern how confined processes
run on the system.

This update fixes the following bug:

• Previously, SELinux returned AVC denial messages during attempts to attach an

LVM volume to a Red Hat OpenStack 3 instance. The relevant SELinux policy rules
have been modified to add an additional MCS attribute for hald_t SELinux domain,
and AVC denial messages are no longer returned when attaching LVM volume to a
Red Hat OpenStack 3 instance. (BZ#973776)

• When using Quantum 2013.1.2 with netns support, several SELinux denials were

produced. This update allows qemu to manage nova lib files, hald to read svirt
images, and AVC denials no longer occur in the described scenario. (BZ#976000)

• Previously, the logrotate daemon rotated logs and tried to update the process

ID (PID) in the "/var/run/openvswitch/ovs-vswitchd.pid" configuration, which
caused AVC denials. Usually, the logrotate script sends a SIGHUP to a daemon to
order it to reopen log files after they were rotated. This update revises the
openvswitch policy, and AVC denials no longer occur in the described scenario.
(BZ#977477)

Users of selinux are advised to upgrade to these updated packages, which fix
these bugs.
