Description Raffael Luthiger 2006-09-02 18:00:57 EDT

Description of problem:
I get no statistics regarding the harddisk. In the log files I have always this
message:
audit(1157232904.384:952): avc:  denied  { append } for  pid=464 comm="smartctl"
name="munin-node.log" dev=hda3 ino=10148693 scontext=user_u:system_r:fsadm_t:s0
tcontext=user_u:object_r:var_log_t:s0 tclass=file

The selinux version is "enforcing".

Version-Release number of selected component (if applicable):
Munin and selinux are both the latest version. (updated today 2.9.06)
Munin 1.2.4-9.fc5
selinux-policy 2.3.7-2.fc5

How reproducible:
Just install munin in default mode.

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:
Statistics about my hard-disk. :)

Comment 1 Kevin Fenzi 2006-09-04 13:18:06 EDT

Thanks for the report. I will see what needs to be done to get this working. 
Likely it will require changes to the selinux restrictive policy...

Comment 2 Raffael Luthiger 2006-09-04 15:34:39 EDT

Thanks. I probably have to clarify. What I do not get is the "Sensors :: HDD
temperature".
I do get the Inode statistics. Just in case you were thinking about the wrong
statistics.

Another thing: Should I open up a new ticket for a similar problem but with the
sendmail statistics? There I get:
"mailstats: /var/log/mail/statistics: Permission denied"
Here it is not a selinux problem, but a general permission problem. imho (Or at
least I have no entries in /val/log/messages)

Comment 3 Kevin Fenzi 2006-09-17 17:23:32 EDT

Sorry for the delay in getting back to you on this bug. 

A few questions to help pinpoint things:

- What is SELINUXTYPE set to in /etc/sysconfig/selinux?

- What is in your /etc/munin/plugin-conf.d/sendmail file?

Comment 4 Raffael Luthiger 2006-09-17 19:09:40 EDT

No problem. I had other (more important) stuff to do as well :)

[root@ras ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
SELINUX=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted

# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0
[root@ras ~]# cat /etc/munin/plugin-conf.d/sendmail
[sendmail*]
user root
env.mspqueue /var/spool/clientmqueue

Comment 5 Raffael Luthiger 2006-10-10 12:09:56 EDT

Is there anything I can help with?

Comment 6 Kevin Fenzi 2006-10-10 12:47:33 EDT

Sorry about the delay... 

Basically selinux is preventing the 'smartctl' program from appending to the 
munin-node.log. In normal cases it shouldn't need to log anything there.
Can you run the following and tell me the output: 

su munin -s /bin/bash -c '/etc/munin/plugins/hddtemp_smartctl'

On the sendmail issue, where are you seeing that error? in the /var/log/munin/
munin-node.log? Have you restarted munin node recently? The /etc/munin/plugin-
conf.d/sendmail file should tell it to run that plugin as root and it should be 
able to read the mail stats that way.

Comment 7 Raffael Luthiger 2006-10-10 13:23:53 EDT

no problem.

When I enter the mentioned command above I get no output at all.

I haven't restarted the munin-node for the past 2 month or so. But I did it now.
And the sendmail messages seem to be gone. I will check later if I get some
statistics now as well.

But the smartctl error remains.

Comment 8 Kevin Fenzi 2006-10-10 13:29:52 EDT

ok. Humm... 

can you create a /etc/munin/plugin-conf.d/hddtemp_smartctl file and put in it: 

[hddtemp_smartctl]
user root

And restart munin-node and see if that solves the hdtemp issue?

Comment 9 Raffael Luthiger 2006-10-10 14:33:09 EDT

yupp. that was it.

I get now statistics for both modules.

Thank you very much.

(I leave the ticket open, in case you need to write something more. From my side
it is closed)

Comment 10 Kevin Fenzi 2006-10-20 15:04:56 EDT

ok. I have just pushed out a update to munin 1.2.5 that includes this fix. 
I am going to close this bug now, but if you spot any problems with the new 
version, feel free to re-open or file a new bug. 

Thanks again for the bugreport.
