Description Niranjan Mallapadi Raghavender 2013-12-30 04:53:56 UTC
Description of problem:
1. I am using irssi with libnotify , I am following http://code.google.com/p/irssi-libnotify/wiki/MainPage as reference document.

2. currently after setting up the configuration, selinux denies irssi to send messages  as irssi seems to execute /bin/bash. 

Is there a sane way to make this work ?
SELinux is preventing /usr/bin/irssi from 'execute' accesses on the file /usr/bin/bash.

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

If you believe that irssi should be allowed execute access on the bash file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep irssi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

0013c7e0cfb8a4ba42f4219554adcf394030a081 allows this in git.

If you execute 
# grep irssi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

It should allow this access.
