Description Phil Anderson 2011-01-16 04:49:28 EST
Several fail2ban files require files in /tmp:

SELinux currently blocks this.  I used the following to resolve the problem:

require {
	type tmp_t;
	type fail2ban_t;
	class dir { write remove_name add_name };
	class file { write getattr read create unlink open append };

Take note of bug 669965 which is about fail2ban using insecure tmp files.  Probably best to wait for that to be resolved before changing the SELinux policy, in case they put temp files in a different location.
Comment 1 Miroslav Grepl 2011-01-17 06:39:56 EST
Yes, daemons should not used /tmp. /tmp is for users to store their stuff. 

But I am interested about AVC messages which you are seeing. Could you attach these AVC msgs. I would like to see "comm=" field.

Thank you.

AVC messages caused by dshield action

As produced by the default /etc/fail2ban/action.d/dshield.conf contained in fail2ban-0.8.4-25.fc14.noarch.
Comment 3 Daniel Walsh 2011-01-17 11:45:16 EST
Can  you change dshield to use /var/run/fail2ban and make sure nothing in fail2ban uses /tmp.
Comment 4 Daniel Walsh 2011-01-17 11:47:29 EST

If you execute the following it should fix your problem.

# sed -i 's|/tmp|/var/run/fail2ban|g' /etc/fail2ban/action.d/dshield.conf

Comment 5 Phil Anderson 2011-01-17 19:43:23 EST
Yes, I have been running it like that for a few days now without problems.  But, in terms of updating the package, I suspect that /var/run isn't the place, rather /var/lib, as some of those files stay between restarts/reboots.  But, that's for bug 66965 I guess.
Comment 6 Daniel Walsh 2011-01-18 10:59:09 EST
/var/lib/fail2ban is fine with me.

I think the new fail2ban-0.8.4-27.fc14 version is broken, I can't start the ssh-jail with SELinux enabled. 



for more informations.

I switched back to the version fail2ban-0.8.4-25.fc14, which still works.
Comment 16 Marco Guazzone 2011-06-05 04:01:09 EDT
