Bug 543045

\u0421\u0432\u043e\u0434\u043a\u0430:

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

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

You can generate a local policy module to allow this access - see FAQ
