+Subject: [PATCH] policy/modules/roles/sysadm: MLS - sysadm rw to clearance
+
+The two new rules make sysadm_t domain MLS trusted for:
+ - reading from files at all levels.
+ - writing to processes up to its clearance(s0-s15).
+
+With default MLS policy, root user would login in as sysadm_t:s0 by
+default. Most processes will run in sysadm_t:s0 because no
+domtrans/rangetrans rules, as a result, even root could not access
+high level files/processes.
+
+So with the two new rules, root user could work easier in MLS policy.
+
+Upstream-Status: Inappropriate [embedded specific]
