:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that systemctl should be allowed open access on the cgroup.procs 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 systemctl /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Andre Inglis 2011-11-08 16:44:30 UTC
This bug is very similiar to this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=748921


Steps to produce bug:

1. Open 'Time and Settings'

2. SELinux comes up with bug alert #748921 as mentioned above.

3. Follow the solution as per advised in the bug report:

"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 systemctl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp"

4. Open terminal and enter (as root):

grep systemctl /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp"

5. Reboot

6. Open 'Time and Settings'

7. SELinux comes up with this new bug. The SELinux Alert Browser did not find a duplicate for this bug.
