Description Rahul Sundaram 2013-02-12 20:28:53 UTC
Description of problem:
SELinux is preventing /usr/sbin/dnsmasq from 'search' accesses on the directory NetworkManager.

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

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