mcstransd never implemented this permission. To keep permission indices
lined up, replace the permission with "unused_perm" to make it clear that
it has no effect.
This patch properly completes the implementation of the MLS file relabel attributes. In the previous patch [http://oss.tresys.com/pipermail/refpolicy/2016-July/008038.html], a new attribute, mlsfilerelabetoclr, was created. There should have been a second attribute, mlsfilerelabel, created instead of overloading mlsfilewrite for this privilege. I concur with creating new attributes for this situation. I have created the patch below.

Add MLS constraints for several network related access controls including
the new ingress/egress controls and the older Secmark controls. Based on
the following post to the SELinux Reference Policy mailing list:

Attached is a patch which I've tested against selinux-policy-2.4.2-1
that implements this additional constraint. The name is still a bit
forced, but it works.
