   Log message:
   Fix CVE-2011-4028: File disclosure vulnerability.
   use O_NOFOLLOW to open the existing lock file, so symbolic links
   aren't followed, thus avoid revealing if it point to an existing
   file. Signed-off-by: Matthieu Herrb <matthieu.herrb@laas.fr>

   Fix CVE-2011-4029: File permission change vulnerability.
   Use fchmod() to change permissions of the lock file instead of
   chmod(), thus avoid the race that can be exploited to set a symbolic
   link to any file or directory in the system. Signed-off-by: Matthieu
