Subject: [PATCH] Fix MLS handling in selinux tests
From: Stephen Smalley <sds () tycho ! nsa ! gov>
Date: 2009-04-30 15:20:44
Message-ID: 1241104844.27331.64.camel () localhost ! localdomain
[Download RAW message or body]
Some of the selinux tests were using full security contexts but predated
MCS/MLS and thus lacked a MLS field. This broke testing if MLS was
enabled in the policy but mcstransd was not running. Change some of the
tests to avoid the need to use full contexts at all, and others to
conditionally append a MLS suffix if MLS is enabled.
