Does ls -lZ /proc/self/fd show anything stange?
Yes it does, fd 25:
[root@gerbil ~]# ls -lZ /proc/self/fd
lrwx------ root root unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 0 ->
/dev/pts/0

It would appear fd 3 is what ls is using to read the entries in
/proc/self/fd (also verified with strace):
[root@gerbil ~]# ls -lZ /proc/self/fd &
lrwx------ root root unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 0 ->
/dev/pts/0

I've been trying to figure out the mysteries of NetworkManager and
mixing wired and wireless connections. I just noticed that if I don't
have NetworkManager configured at boot, I don't get the AVC denial nor
do I see the socket on fd 25.
Additionally, I noticed that even if NetworkManager is configured at
boot, I don't see the AVC denial/fd 25 issue when running in a virtual
terminal. Upon further investigation, this issue only seems to occur
when running KDE+konsole, but not KDE+gnome-terminal, nor
GNOME+konsole, nor GNOME+gnome-terminal.
Also, I don't see fd 25 when connecting remotely (over SSH) and
running the above ls command.
