From: dh.herrmann@gmail.com (David Herrmann) Date: Fri, 4 May 2018 16:28:20 +0200 Subject: [PATCH v2 2/4] net: hook socketpair() into LSM In-Reply-To: <20180504142822.15233-1-dh.herrmann@gmail.com> References: <20180504142822.15233-1-dh.herrmann@gmail.com> Message-ID: <20180504142822.15233-3-dh.herrmann@gmail.com> To: linux-security-module@vger.kernel.org List-Id: linux-security-module.vger.kernel.org Use the newly created LSM-hook for socketpair(). The default hook return-value is 0, so behavior stays the same unless LSMs start using this hook.
