Bug 557873

Summary:

SELinux is preventing /sbin/iptables-multi access to a leaked tcp_socket file
descriptor.

Detailed Description:

[iptables has a permissive type (iptables_t). This access was not denied.]

SELinux denied access requested by the iptables command. It looks like this is
either a leaked descriptor or iptables 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 tcp_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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)
