Registered in England and Wales under Company Registration No. 3798903 From: David Howells Subject: [PATCH 26/59] CRED: Wrap task credential accesses in the FAT filesystem To: linux-kernel@vger.kernel.org Cc: linux-security-module@vger.kernel.org, David Howells , Serge Hallyn , OGAWA Hirofumi Date: Wed, 27 Aug 2008 14:47:56 +0100 Message-ID: <20080827134756.19980.73543.stgit@warthog.procyon.org.uk> In-Reply-To: <20080827134541.19980.61042.stgit@warthog.procyon.org.uk> References: <20080827134541.19980.61042.stgit@warthog.procyon.org.uk> User-Agent: StGIT/0.14.3 MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1854 Lines: 54 Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.
