Description Matthew Miller 2012-10-17 20:48:15 UTC
Description of problem:
Fresh install of F18 beta with default packages. Did yum groupinstall of xfce, and logged into xfce. This is one of several immediate AVCs.

Additional info:
libreport version: 2.0.16
kernel:         3.6.2-2.fc18.x86_64

:Below is the report from the SELinux troubleshooter. But, why is blueman-mechanism trying to read /var/tmp in the first place?
:SELinux is preventing /usr/bin/python2.7 from 'read' accesses on the directory /var/tmp.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that python2.7 should be allowed read access on the tmp directory by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep blueman-mechani /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 3 Matthew Miller 2012-10-17 20:50:26 UTC
Although this is an SELinux denial, before changing the policy, I wonder if someone who knows this package could verify that it really needs access to /var/tmp?

Comment 4 Ondra Pelech 2012-10-26 11:17:59 UTC
1. install blueman
2. run blueman

Package: (null)
OS Release: Fedora release 17 (Beefy Miracle)

Comment 5 Andrew Manison 2012-10-28 17:22:46 UTC
Logging in to a newly installed system, with XFCE desktop. Error appears on every login.

Comment 6 Miroslav Grepl 2012-10-29 09:16:40 UTC
It relates with sys_nice/setsched

Comment 7 Stuart 2012-11-03 08:42:34 UTC
Fresh installation of fedora 64 as a virtualbox guest vm. Receive an SELinux warning stating SELinux is preventing /usr/bin/python2.7 from reading tmp

Comment 8 Juan Manuel Rodriguez 2013-12-09 23:06:29 UTC
Hi. I'm closing this bug as Blueman has been retired from Fedora. 

If you wish to file a bug against upstream, a new Blueman fork has been created in this github repository. [1]

I apologize for the inconvenience.
