Description Eddie Lania 2011-07-25 20:00:44 UTC
SELinux is preventing /sbin/ldconfig from 'execute' accesses on the file /sbin/ldconfig.

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

If you believe that ldconfig should be allowed execute access on the ldconfig 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 ldconfig /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-07-25 20:14:57 UTC
Why is fail2ban executing ldconfig?

Comment 2 Miroslav Grepl 2011-07-26 06:20:54 UTC
Not sure but we have this in Rawhide.

Comment 3 Daniel Walsh 2011-07-26 13:48:24 UTC
Ok but it looks like fail2ban is downloading stuff and then running ldconfig on it.  Seems a little dangerous.

Comment 4 Jonathan Underwood 2011-07-26 15:09:51 UTC
It's a while since I've used fail2ban, as it's somewhat abondonware at this point, but this is not behaviour I would expect to be seeing from this program at all.
