Subject: [PATCH 2/3] net/unix: hook unix_socketpair() into LSM
Date: Mon, 23 Apr 2018 15:30:14 +0200 [thread overview]
Message-ID: <20180423133015.5455-3-dh.herrmann@gmail.com> (raw)
In-Reply-To: <20180423133015.5455-1-dh.herrmann@gmail.com>
Use the newly created LSM-hook for unix_socketpair(). The default hook
return-value is 0, so behavior stays the same unless LSMs start using
this hook.
