Subject: [PATCH] security: selinux: allow per-file labeling for cgroupfs
Date: Thu, 9 Feb 2017 16:58:23 +0100 [thread overview]
Message-ID: <20170209155823.22148-1-runcom@redhat.com> (raw)
This patch allows genfscon per-file labeling for cgroupfs. For instance,
this allows to label the "release_agent" file within each
cgroup mount and limit writes to it.
