Title:
  Multiple drivers set insecure file permissions

Status in Cinder:
  In Progress
Status in OpenStack Security Notes:
  Fix Released

Bug description:
  GPFS from various places calls "chmod 666" as root:

  ./cinder/volume/drivers/gpfs.py:        self._execute('chmod', '666', path, run_as_root=True)
  ./cinder/volume/drivers/gpfs.py:            self._execute('chmod', '666', vol_path, run_as_root=True)

  the Huawei driver sets 777 permissions as root on some files:

  ./cinder/volume/drivers/huawei/ssh_common.py: utils.execute('chmod', '777', filepath, run_as_root=True)
  ./cinder/volume/drivers/huawei/rest_common.py: utils.execute('chmod', '777', filepath, run_as_root=True)

  the Scality driver sets 666 permissions on all volumes:

  cinder/volume/drivers/scality.py:

      def _create_file(self, path, size):
          with open(path, "ab") as f:
              f.truncate(size)
          os.chmod(path, 0o666)

  Similarly, the NFS and NEXENTA driver have an implementation of

  def _set_rw_permissions_for_all()

  that is being called on all newly created volumes.
