Bug 633288

Summary:

SELinux is preventing /sbin/dhclient access to a leaked netlink_route_socket
file descriptor.

Detailed Description:

[dhclient has a permissive type (dhcpc_t). This access was not denied.]

SELinux denied access requested by the dhclient command. It looks like this is
either a leaked descriptor or dhclient output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the netlink_route_socket. You should generate a bugzilla on selinux-policy, and
it will get routed to the appropriate package. You can safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
