Description Steve Tyler 2011-04-07 13:28:04 UTC
SELinux is preventing /bin/systemctl from 'search' accesses on the directory /sys/fs/cgroup.

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

If you believe that systemctl should be allowed search access on the cgroup directory 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 Daniel Walsh 2011-04-07 14:37:03 UTC
gnomeclock_systemctl_t  does not exist?  Are you installing some custom policy?

Comment 2 Steve Tyler 2011-04-07 17:32:27 UTC
(In reply to comment #1)
> gnomeclock_systemctl_t  does not exist?  Are you installing some custom policy?

Not knowingly. I am using:
[joeblow@fir ~]$ rpm -qa 'selinux*' | sort
selinux-policy-3.9.16-13.fc15.noarch
selinux-policy-targeted-3.9.16-13.fc15.noarch

I had used chkconfig to enable ntpd as a workaround for Bug 675278, and
used chkconfig to disable ntpd before testing, if that matters.

I rebooted after updating to selinux-policy-3.9.16-13.

Comment 3 Miroslav Grepl 2011-04-07 17:41:17 UTC
Dan,
this is a scratch build for testing.
