SELinux is preventing /bin/bash "getattr" access on /proc//net/if_inet6.

Detailed Description:

SELinux denied access requested by ifdown-ipv6. It is not expected that this
access is required by ifdown-ipv6 and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

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