Description Tom London 2009-06-22 19:19:37 EDT
The following was filed automatically by setroubleshoot:


SELinux is preventing udevd (udev_t) "read" anon_inodefs_t.

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux denied access requested by udevd. It is not expected that this access is
required by udevd 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) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Comment 1 Tom London 2009-06-22 19:24:42 EDT
This was a test of setroubleshoot-2.2.7-1.fc12.x86_64.

"Submit Bug" now appears to work!

If the above is fixed in selinux-policy-3.6.19-1.fc12.noarch, this can be closed.
Comment 2 Daniel Walsh 2009-06-24 17:10:41 EDT
The interesting thing to see, is whether or not a duplicate bug from another account gets appended to this one.
