From 0036dfb42db831e2dd6c6dc71c093e983a30dbd6 Mon Sep 17 00:00:00 2001
From: Xin Ouyang <Xin.Ouyang@windriver.com>
Date: Thu, 22 Aug 2013 13:37:23 +0800
Subject: [PATCH 18/34] policy/module/logging: add rules for the symlink of
/var/log
/var/log is a symlink in poky, so we need allow rules for files to read
lnk_file while doing search/list/delete/rw... in /var/log/ directory.
Upstream-Status: Inappropriate [only for Poky]
