Subject: what's up with mac_admin

type=AVC msg=audit(1552226284.038:2422): avc: denied { mac_admin } for
pid=8289 comm="rsync" capability=33
scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=capability2
permissive=0

The above is from running rsync with the -X option.

$ grep -R mac_admin .
./policy/flask/access_vectors: mac_admin # unused by SELinux
./policy/modules/apps/livecd.te:dontaudit livecd_t self:capability2 mac_admin;

Grepping the git policy shows that there's a comment saying it's unused as
well as a dontaudit rule indicating that it has been used for some time.

Its for setting invalid labels. Something you generally want to avoid.

Correct. There used to be a neverallow, but when that was removed, we
forgot to remove the comment in access_vectors. It's gone now.
