From mboxrd@z Thu Jan 1 00:00:00 1970 From: Richard Guy Briggs Subject: [PATCH 0/3] [RFC] X32: fix syscall_get_nr while not breaking seccomp BPF Date: Thu, 10 Jul 2014 23:38:11 -0400 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-audit-bounces@redhat.com Errors-To: linux-audit-bounces@redhat.com To: linux-audit@redhat.com, linux-kernel@vger.kernel.org Cc: Will Drewry , Richard Guy Briggs , Paul Moore , "H. Peter Anvin" List-Id: linux-audit@redhat.com This set reverts commit 8b4b9f2 which broke audit and potentially other users of syscall_get_nr() which depend on that call as named without being overloaded by architecture bits. It will satisfy other regular users of syscall_get_nr() and syscall_get_arch() without changing the seccomp interface to BPF. A new ARCH definition, AUDIT_ARCH_X86_X32, was added for syscall_get_arch(). Cc: Paul Moore Cc: Eric Paris Cc: Al Viro Cc: Will Drewry Cc: H.
