Description NickG 2013-08-08 04:21:17 EDT
Description of problem:
Started viewing http://mtvnmobile.vo.llnwd.net/kip0/_pxn=0+_pxK=18639/44620/mtvnorigin/gsp.comedystor/com/colbert/season_09/episode_135/cr_09135_02_1280x720_3500_h32.mp4 in Firefox.

Right clicked the video as it was playing and chose to View in Totem.

Totem loads and requests to start playback and selinux steps in with it's standard "You want to use your laptop for 'NORMAL USAGE'?, No no no - you can't do that."

 
SELinux is preventing /usr/bin/totem from 'write' accesses on the sock_file pkcs11.

*****  Plugin mozplugger (99.1 confidence) suggests  *************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests  ***************************

If you believe that totem should be allowed write access on the pkcs11 sock_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep totem /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-08-09 08:30:23 EDT
Most likely need to turn off the protection.


# setsebool unconfined_mozilla_plugin_transition 0
Comment 2 NickG 2013-08-09 08:40:21 EDT
Agreed with the fix. But if shipping selinux is the way forward, the default policies really need to get out of the way.
Comment 3 Daniel Walsh 2013-08-09 09:00:09 EDT
Well then we would protect nobody from bad plugins.  Since no one would no to turn it on.
