Summary:

SELinux is preventing /sbin/ip6tables-multi access to a leaked /proc/mtrr file
descriptor.

Detailed Description:

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

SELinux denied access requested by the ip6tables-resto command. It looks like
this is either a leaked descriptor or ip6tables-resto 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 /proc/mtrr. 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)
