Bug 531726

Summary:

SELinux is preventing /usr/lib/cups/filter/hpcups "name_bind" access.

Detailed Description:

[hpcups has a permissive type (cupsd_t). This access was not denied.]

SELinux denied access requested by hpcups. It is not expected that this access
is required by hpcups 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.
