Sumário:

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

Descrição detalhada:

[SElinux está em modo permissivo. Esse acesso não foi negado.]

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 /dev/mull.
You should generate a bugzilla on selinux-policy, and it will get routed to the
appropriate package. You can safely ignore this avc.

Permitindo acesso:

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