A synchronous failure there - -ENOMEM\nfrom the route work allocation, an SA query that cannot be set up, a\nRoCE route with no usable device - makes addr_handler() destroy the\nid the event was delivered on.  That id is ic->i_cm_id, and nothing\nclears the pointer: the connection sits in RDS_CONN_CONNECTING with a\nfreed id until its shutdown calls rdma_disconnect() and\nrdma_destroy_id() on it.\n\nThe ROUTE_RESOLVED case already avoids this: rds_ib_cm_initiate_connect()\nforces a zero return while ic->i_cm_id == cm_id, as the comment there\nexplains.  Do the same here - drop the connection and return 0 - so\nthe id stays RDS's to destroy from the shutdown, and the reconnect\ngets a fresh one."
