SELinux is preventing /usr/bin/updatedb "getattr" access on

Detailed Description:

SELinux denied access requested by updatedb. It is not expected that this access
is required by updatedb 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Daniel Walsh 2010-07-28 14:14:11 UTC
This looks like local customization.  What file system is mounted at /mnt/sysroot?

Is this a file system from a labeled disk?

Comment 2 Eric Blake 2010-07-28 14:24:00 UTC
Yes - it was a temporary mount to an ext4 partition containing a rawhide image (I've set my machine up for dual boot, and was trying to do an off-line repair for an issue in my rawhide boot), so I guess it would be okay to close this out as not a bug, since it won't affect default installs.

Meanwhile, I should probably tweak my updatedb settings to ignore cross-mounted images (as locate should only find programs accessible to the current OS, and not the disk images of other OSs that I have temporarily mounted).

Comment 3 Daniel Walsh 2010-07-28 14:43:29 UTC
Yes, the problem here is labels in Rawhide are not understood in F13.  So it is complaining about the label.
