From f418b006079ce537daf9436215f1d2a47e451602 Mon Sep 17 00:00:00 2001 From: Stephen Smalley Date: Mon, 28 Jul 2008 13:32:38 -0400 Subject: [PATCH] Re: BUG at security/selinux/avc.c:883 (was: Re: linux-next: Tree for July 17: early crash on x86-64) SELinux needs MAY_APPEND to be passed down to the security hook. Otherwise, we get permission denials when only append permission is granted by policy even if the opening process specified O_APPEND. Shows up as a regression in the ltp selinux testsuite, fixed by this patch.
