Description Pierre Ossman 2013-12-18 10:35:55 UTC 
Seen on Fedora 19 and Fedora 20:

$ xauth &
[1] 14712
Using authority file /run/gdm/auth-for-ossman-HdenCT/database
xauth> 
[1]+  Stopped                 xauth

$ ps axZ | grep xauth
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 14712 pts/2 T   0:00 xauth

$ ls -Z /bin/xauth 
-rwxr-xr-x. root root system_u:object_r:xauth_exec_t:s0 /bin/xauth
Comment 1 Daniel Walsh 2013-12-19 20:37:23 UTC 
We removed the transition from unconfined_t to many domains.
Comment 2 Pierre Ossman 2013-12-20 06:18:04 UTC 
Hmm... Ok. This does make it difficult to write file context globs though. The Xauthority file for different users will have different contexts depending on which context the user is allowed to use. Maybe xauth_home_t and such need to go away?
Comment 3 Miroslav Grepl 2013-12-20 09:33:35 UTC 
The reason why we could remove these transitions is the fact we have "File Name Transitions". So for example

$ sesearch -T |grep \".Xauthority
Comment 4 Pierre Ossman 2013-12-20 10:32:40 UTC 
Ah, I see. Thanks. I'll have to look at the current policy and see how to apply similar changes to our policy module.
