Subject: [PATCH 6/6] secmark: export secctx, drop secmark in procfs
Date: Fri, 24 Sep 2010 16:45:52 -0400 [thread overview]
Message-ID: <20100924204552.28355.48988.stgit@paris.rdu.redhat.com> (raw)
In-Reply-To: <20100924204517.28355.42822.stgit@paris.rdu.redhat.com>
The current secmark code exports a secmark= field which just indicates if
there is special labeling on a packet or not. We drop this field as it
isn't particularly useful and instead export a new field secctx= which is
the actual human readable text label.
