  34 # DESCRIPTION:
  35 #
  36 # Attempting to read an xattr on a file for which we have no permissions
  37 # should fail.
  38 #
  39 # STRATEGY:
  40 #       1. Create a file, and set an with an xattr
  41 #       2. Set the octal file permissions to 000 on the file.
  42 #       3. Check that we're unable to read the xattr as a non-root user
  43 #       4. Check that we're unable to write an xattr as a non-root user
