Subject: bug report: potential null deref send_mds_reconnect()
Date: Fri, 14 May 2010 01:36:16 +0200	[thread overview]
Message-ID: <20100513233615.GD5695@bicker> (raw)

This is a Smatch thing.

fs/ceph/mds_client.c +2217 send_mds_reconnect(82) error: we previously assumed 'session' could be null.
  2176          down_read(&mdsc->snap_rwsem);
  2177
  2178          if (!session)
  2179                  goto send;

	If we hit this goto then we will dereference session and oops.

  2180          dout("session %p state %s\n", session,
  2181               session_state_name(session->s_state));
 
regards,
dan carpenter
