Bug 579119

Summary:

SELinux is preventing /usr/bin/xargs access to a leaked file descriptor.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by the xargs command. It looks like this is
either a leaked descriptor or xargs 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 . 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)

audit2allow suggests:

#============= afs_t ==============
#!!!! The source type 'afs_t' can write to a 'file' of the following types:

allow afs_t unlabeled_t:file { read write open };
