Description Till Maas 2011-08-08 19:41:20 UTC
SELinux is preventing /usr/bin/perl from 'create' accesses on the sock_file munin-master-processmanager-20902.sock.

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

If you believe that perl should be allowed create access on the munin-master-processmanager-20902.sock sock_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 munin-update /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Do you know which dirtory munin is trying to do this in?

Comment 3 Till Maas 2011-08-09 19:58:17 UTC

> Do you know which dirtory munin is trying to do this in?

/var/run/munin/

Comment 4 Miroslav Grepl 2011-08-10 07:14:19 UTC
Execute

# restorecon -R -v /var/run/munin

will fix. Not sure how got this mislabeled.

What does

# rpm -qf /var/run/munin

Comment 5 Till Maas 2011-08-11 16:59:04 UTC
# rpm -qf /var/run/munin
munin-1.4.6-1.fc15.noarch

Btw. /var/run is a tmpfs filesystem in F15 and I reboot the system where the problem occured regulary.

Comment 6 Brownout 2011-08-23 11:03:06 UTC
It IS a bug, since the tmpfs gets recreated every reboot the label gets lost.

Comment 7 Daniel Walsh 2011-08-24 02:58:42 UTC
Is there a process within the init system that is creating the munin directory?

Comment 8 Till Maas 2011-08-24 20:13:05 UTC
(In reply to comment #7)
> Is there a process within the init system that is creating the munin directory?

/etc/rc.d/init.d/munin-node

[...]
mkdir -p /var/run/munin 2>/dev/null
chown munin /var/run/munin
[...]

Comment 9 Daniel Walsh 2011-08-26 21:46:45 UTC
It needs 

restorecon /var/run/munin
