Subject: [PATCH 1/1] secid reconcialiation: Replace unlabeled_t with the network_t
Date: Tue, 03 Oct 2006 21:41:51 -0500 [thread overview]
Message-ID: <45231F6F.4030509@trustedcs.com> (raw)
The following replaces unlabeled_t with network_t for
better characterization of the flow out/in checks in
SELinux, as well as to allow for mls packets to
flow out/in from the network since network_t would allow
the full range of MLS labels, as opposed to the unlabeled init sid
that only allows system-hi.
