SELinux is preventing totem (nsplugin_t) "getattr" to /dev/root

Detailed Description:

SELinux denied access requested by totem. It is not expected that this access is
required by totem and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for /dev/root,

restorecon -v '/dev/root'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Comment 1 Daniel Walsh 2008-10-17 16:07:38 EDT
Did mplayer run ok with this AVC?

Fixed in selinux-policy-3.5.13-1.fc10
Comment 2 Alex Chiang 2008-10-18 21:00:49 EDT
Hm, I don't have mplayer installed, and I don't see it in yum either (default repos enabled only).

[achiang@ethanol ~]$ yum search mplayer
Loaded plugins: refresh-packagekit
=============================== Matched: mplayer ===============================
kmplayer.i386 : Video plugin for Konqueror and basic Gstreamer/Xine frontend
vorbisgain.i386 : Adds tags to Ogg Vorbis files to adjust the volume

Am I missing something?
Comment 3 Daniel Walsh 2008-10-20 12:55:50 EDT
Sorry bug overload.  Should have asked if totem ran ok.

mplayer was broken in another bug.
Comment 4 Alex Chiang 2008-10-20 22:57:58 EDT
Yes, totem plays an ogg inline in my browser correctly.

I can also download the ogg, add it to a totem playlist, and it plays correctly as well.
