Description Robert Townley 2010-04-22 09:02:02 UTC
Summary:

SELinux is preventing /usr/bin/pulseaudio "setattr" access on
/var/lib/mpd/.pulse.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by pulseaudio. It is not expected that this
access is required by pulseaudio 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:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2010-04-22 11:43:16 UTC
Was /var/lib/mpd a local customization?

# semange fcontext -a -t pulseaudio_var_lib_t '/var/lib/mpd(/.*)?'
# restorecon -R -v /var/lib/mpd

Should fix.

Comment 2 Miroslav Grepl 2010-04-29 08:48:27 UTC
I am closing it as CANTFIX. That's relating to Music Player Daemon.

Comment 3 Robert Townley 2010-05-01 18:48:46 UTC
i thank you for spending time on a daemon that is not in the Fedora repos.  Is it a CANTFIX simply because it is not in the official Fedora repos or does the mpd use pulseaudio in a way that would never be compatible with selinux.

Comment 4 Daniel Walsh 2010-05-03 18:09:16 UTC
Does the lines above fix the problem?

Comment 5 Robert Townley 2010-05-05 08:59:02 UTC
After doing the following again, that selinux issue no longer appears.  

# semanage fcontext -a -t pulseaudio_var_lib_t '/var/lib/mpd(/.*)?'
# restorecon -R -v /var/lib/mpd

Comment 6 Daniel Walsh 2010-05-05 14:52:33 UTC
That is what the current policy has for labeling.  If you can get mpd into fedora, we will write policy for it.

Miroslav can you add this labeling to F12.  It is in F13.
