Description Amit Shah 2011-05-25 06:31:10 UTC
SELinux is preventing /usr/sbin/dnsmasq from 'open' accesses on the file nm-dns-dnsmasq.conf.

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

If you believe that dnsmasq should be allowed open access on the nm-dns-dnsmasq.conf 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 dnsmasq /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
