The smp_distribute_keys() function calls smp_notify_keys() which in turn calls l2cap_conn_update_id_addr(). The l2cap_conn_update_id_addr() function will iterate through all L2CAP channels for the respective connection: lock the channel, update the address information and unlock the channel. Since SMP is now using l2cap_chan callbacks each callback is called with the channel lock held. Therefore, calling l2cap_conn_update_id_addr() would cause a deadlock calling l2cap_chan_lock() on the SMP channel. This patch moves calling smp_distribute_keys() through a workqueue so that it is never called from an L2CAP channel callback.
