Hi Minho, * Minho Ban <mhban@xxxxxxxxxxx> [2012-05-21 09:56:40 +0900]: > l2cap_sock_kill can be called in l2cap_sock_release and l2cap_sock_close_cb > either. This lead l2cap_chan_destroy to be called twice for same channel. > To prevent double list_del and double chan_put, chan_destroy should be protected > with chan->refcnt and chan_list_lock so that reentrance could be forbidden. Even if l2cap_sock_kill() is called twice it will call l2cap_chan_destroy() only once. If this is not happening we just have a broken piece of code somewhere else and not here.
