Description M. A. MacLain 2011-03-19 13:35:08 UTC
SELinux is preventing /usr/libexec/gvfs-gdu-volume-monitor from 'getattr' accesses on the file /media/2357f634-9244-4ee3-9836-51ef3bbd4336/null.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that gvfs-gdu-volume-monitor should be allowed getattr access on the null file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep gvfs-gdu-volume /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-03-21 22:00:42 UTC
This looks like you could have a badly mislabeled system.  I have no idea why gdm woul dbe launcing gvfs-gdu-volume and why this would be looking at

/media/2357f634-9244-4ee3-9836-51ef3bbd4336/null

And I have no idea why this is labeled root_t.

Comment 2 Daniel Walsh 2011-03-31 19:56:17 UTC
Is this still a problem?
