ipoib_mcast_stop_thread currently tests mcast->query and if it is NULL, does not perform wait_for_completion on the mcast and frees the mcast object directly. However, since both operations are done without locking, it is possible that ipoib_mcast_join_complete is in progress on this mcast object and has set mcast->query to NULL already. Solve this by: - taking priv->lock before we change mcast->query in ipoib_mcast_join_complete, and keeping it until we no longer need the mcast object - taking priv->lock around mcast->query test in ipoib_mcast_stop_thread Signed-off-by: Michael S.
