Description Rahul Sundaram 2010-06-08 06:31:25 EDT

SELinux is preventing /usr/bin/pulseaudio "read" access on

Detailed Description:

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

I could create 10 bugs but I won't so I attach a file with 10 more various AVCs from pulseaudio. Please have a look at these before pushing that update.

How to reproduce:
1. switch to permissive mode
2. yum install mpd
3. /etc/init.d/start mpd
Comment 4 Viktor Erdelyi 2010-06-14 12:06:27 EDT
I forgot to add that one of them told me to restore a context, I did and it didn't help.
Comment 5 Miroslav Grepl 2010-06-14 12:19:25 EDT
I am just adding mpd policy to selinux-policy and I will build it and create a new update with this policy today.

Comment 7 Fedora Update System 2010-06-14 15:29:53 EDT
selinux-policy-3.7.19-28.fc13 has been submitted as an update for Fedora 13.
Comment 8 Viktor Erdelyi 2010-06-14 15:46:26 EDT
I have just installed this one from koji, and got 14 other AVCs when starting mpd
from programs like mpd, gconf-helper, pulseaudio, rtkit-daemon...
Comment 9 Miroslav Grepl 2010-06-14 16:08:11 EDT
Did you install also selinux-policy-targeted package? 

If yes, could you attach your /var/log/audit/audit.log.

Audit log (tar.bz2)

I had to install it to satisfy its dependencies. And the AVCs say it's the -28 version.
Audit log attached.
Comment 11 Miroslav Grepl 2010-06-14 17:06:33 EDT
thanks for testing. 

Are you running PulseAudio as system wide daemon?
Comment 12 Viktor Erdelyi 2010-06-14 17:40:46 EDT
Not sure, I'm running on defaults, as far as pulseaudio is concerned. Maybe it has to do something with the fact that I'm running KDE (with some default pulseaudio intergration bits).

Comment 13 Viktor Erdelyi 2010-06-14 17:42:31 EDT
Well, daemon would mean -D option, wouldn't it? It isn't there so maybe it's not running as a daemon. But I'm no pulseaudio expert.

Comment 16 Miroslav Grepl 2010-06-16 06:16:39 EDT

thanks. Could you also test the latest F13 policy from koji?
Comment 17 Viktor Erdelyi 2010-06-16 09:18:07 EDT
Same AVCs with selinux-policy-3.7.19-29.fc13. (In the changelog pulseaudio/mpd was't mentioned at all. It didn't even have a chance to work.)

selinux-policy-3.7.19-28.fc13 has been pushed to the Fedora 13 stable repository.  If problems still persist, please make note of it in this bug report.
