Bug 551676

Summary:

SELinux is preventing /sbin/ip access to a leaked fifo_file file descriptor.

Detailed Description:

[ip has a permissive type (ifconfig_t). This access was not denied.]

SELinux denied access requested by the ip command. It looks like this is either
a leaked descriptor or ip 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 fifo_file.
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)
