3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Paris <epa...@redhat.com>
commit 9085a6422900092886da8c404e1c5340c4ff1cbf upstream.
When writing policy via /sys/fs/selinux/policy I wrote the type and class
of filename trans rules in CPU endian instead of little endian. On
x86_64 this works just fine, but it means that on big endian arch's like
ppc64 and s390 userspace reads the policy and converts it from
le32_to_cpu. So the values are all screwed up. Write the values in le
format like it should have been to start.
