Summary: SELinux is preventing /usr/sbin/dnsmasq "dac_override" access . Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by dnsmasq. It is not expected that this access is required by dnsmasq and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

I get this together with bug 564277 whenever I (re)start dnsmasq. # /sbin/service dnsmasq restart I use dnsmasq as a local name server and have it reload its configuration triggered by NetworkManager changing the network connection.
