Bug 594014

Summary:

SELinux is preventing /bin/mount access to a leaked fifo_file file descriptor.

Detailed Description:

[mount has a permissive type (mount_t). This access was not denied.]

SELinux denied access requested by the mount command. It looks like this is
either a leaked descriptor or mount 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 fifo_file. 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
