Subject: [PATCH 12/14] user_ns: target af_key capability check
Date: Tue, 26 Jul 2011 18:58:35 +0000 [thread overview]
Message-ID: <1311706717-7398-13-git-send-email-serge@hallyn.com> (raw)
In-Reply-To: <1311706717-7398-1-git-send-email-serge@hallyn.com>
From: Serge E. Hallyn <serge.hallyn@canonical.com>
This presumes that it really is complete wrt network namespaces. Looking
at the code it appears to be.
