Description Danny 2009-12-03 12:30:30 UTC
Summary:

SELinux is preventing /sbin/setfiles access to a leaked unix_stream_socket file
descriptor.

Detailed Description:

[restorecon has a permissive type (setfiles_t). This access was not denied.]

SELinux denied access requested by the restorecon command. It looks like this is
either a leaked descriptor or restorecon 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 unix_stream_socket. 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)

Comment 1 Daniel Walsh 2009-12-03 15:10:37 UTC
You can ignore this for now, as it is just a leaked file descriptor,  Will dontaudit in the next release.
