Subject: [PATCH v4 23/23] AppArmor: Remove the exclusive flag
Date: Wed, 26 Jun 2019 12:22:34 -0700 [thread overview]
Message-ID: <20190626192234.11725-24-casey@schaufler-ca.com> (raw)
In-Reply-To: <20190626192234.11725-1-casey@schaufler-ca.com>
With the inclusion of the "display" process attribute
mechanism AppArmor no longer needs to be treated as an
"exclusive" security module. Remove the flag that indicates
it is exclusive. Remove the stub getpeersec_dgram AppArmor
hook as it has no effect in the single LSM case and
interferes in the multiple LSM case.
