Subject: [PATCH 3/3] SELinux: flush the avc before disabling SELinux
Date: Sat, 12 Sep 2009 22:54:23 -0400 [thread overview]
Message-ID: <20090913025423.6583.62118.stgit@paris.rdu.redhat.com> (raw)
In-Reply-To: <20090913025409.6583.58777.stgit@paris.rdu.redhat.com>
Before SELinux is disabled at boot it can create AVC entries. This patch
will flush those entries before disabling SELinux.
