Description Moez Roy 2013-08-24 04:26:13 UTC
Description of problem:
SELinux is preventing /usr/bin/gnome-shell from read, write access on the chr_file rfkill.

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

If you believe that gnome-shell should be allowed read write access on the rfkill chr_file 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 gnome-shell /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Is this happening before you login or are you logging into the system and your context is still xdm_t?
