Summary:

SELinux is preventing ip-up "ioctl" access on /etc/ppp/ip-up.

Detailed Description:

SELinux denied access requested by ip-up. It is not expected that this access is
required by ip-up 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
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
