SELinux is preventing Samba (/usr/sbin/smbd) "getattr" access to /tmp/.X0-lock.

Detailed Description:

SELinux denied samba access to /tmp/.X0-lock. If you want to share this
directory with samba it has to have a file context label of samba_share_t. If
you did not intend to use /tmp/.X0-lock as a samba repository it could indicate
either a bug or it could signal a intrusion attempt. Please refer to 'man
samba_selinux' for more information on setting up Samba and SELinux.

Allowing Access:

You can alter the file context by executing chcon -R -t samba_share_t
'/tmp/.X0-lock' You must also change the default file context files on the
system in order to preserve them even on a full relabel. "semanage fcontext -a
-t samba_share_t '/tmp/.X0-lock'"

Fix Command:

chcon -R -t samba_share_t '/tmp/.X0-lock'

How did you get this to happen?  Were you sharing the /tmp directory via samba?

Comment 2 Bug Zapper 2010-11-03 14:09:12 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
