From bf6d0f5dcda17df3cc5577e203d0f8ea1c2ad6aa Mon Sep 17 00:00:00 2001 From: Mimi Zohar Date: Thu, 18 Aug 2011 18:07:44 -0400 Subject: evm: posix acls modify i_mode The posix xattr acls are 'system' prefixed, which normally would not affect security.evm. An interesting side affect of writing posix xattr acls is their modifying of the i_mode, which is included in security.evm. This patch updates security.evm when posix xattr acls are written.
