Description Dawid Zamirski 2009-10-06 14:53:14 UTC
The following was filed automatically by setroubleshoot:

Summary:

SELinux is preventing /sbin/consoletype access to a leaked unix_dgram_socket
file descriptor.

Detailed Description:

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

SELinux denied access requested by the consoletype command. It looks like this
is either a leaked descriptor or consoletype 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_dgram_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 2009-10-06 15:02:23 UTC
This is just acontinuation of the previous leak.  If you were running in enforcing mode the leak would have been closed before getting to this point.
