Description Fabien Archambault 2011-04-22 07:25:11 UTC
SELinux is preventing /usr/libexec/mission-control-5 from 'read' accesses on the unix_stream_socket Unknown.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that mission-control-5 should be allowed read access on the Unknown unix_stream_socket 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 mission-control /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Did you remove telepathy policy module?

I have the same problem, and it's a new install of fedora 15, I haven't removed anything.

Comment 5 Fabien Archambault 2011-04-22 09:20:41 UTC
I was just doing the update in F15 this morning.
Telepathy was not launched.

Comment 6 Daniel Walsh 2011-04-22 11:40:37 UTC
When the transition was removed in policy, Suddenly unconfined_r:telepathy* context is no longer valid.


If you kill all your telepathy processes, and restart them, the problem will go away.

Comment 7 Daniel Walsh 2011-04-22 11:41:11 UTC
You can just log out and back in to make sure.

Comment 8 Miroslav Grepl 2011-04-22 12:50:56 UTC
Yes, the transition was removed in selinux-policy-3.9.16-16.fc15.

Hmmm, I've been getting hammered with bug reports and emails about empathy (or more specifically telepathy-mission-control) no longer working after installing this policy (selinux-policy-3.9.16-16) from the updates-testing repo. I installed it myself, and haven't been able to get empathy to work since then.

Comment 10 Daniel Walsh 2011-04-25 13:56:39 UTC
You have to killall the telepathy sessions and restart, or logout and everything shoudl work.

Did that (and also rebooted) and telepathy-mission-control is still being prevented from starting.

Same here.

Comment 13 Daniel Walsh 2011-04-25 14:45:07 UTC
Could you attach the AVC's after reboot?

SELinux log messages

Dan, I've downgraded my version of selinux-policy to get empathy working again, but I grepped my logs from the days I had the *-16 version installed for references to 'avc' & 'SELinux' in the hopes it will provide you with the information you're looking for. If there is any other info you need just contact me. Thanks!

Comment 15 Zdenek Janecek 2011-04-25 16:27:19 UTC
It was discussed in the different bug and I don't remember where. This should help:

sudo chcon -t bin_t /usr/libexec/mission-control*  /usr/libexec/telepathy*

I haven't any problem now.

Comment 16 Daniel Walsh 2011-04-25 17:27:19 UTC
I just recreated it also.  I made some updates to selinux policy pool that will allow the transition and allow telepathy to connect to any port for now.

Have you tried the new policy?

> Have you tried the new policy?

Yes, I've installed selinux-policy-3.9.16-17, and it does fix the telepathy bug introduced from selinux-policy-3.9.16-16. It would probably be worthwhile to push selinux-policy-*.17 to bodhi so this bug doesn't keep getting dup bug comments.

Comment 26 Miroslav Grepl 2011-04-27 13:13:27 UTC
Yes, which I will do today.
