Can you test just the one liner fix below?@@ -1452,7 +1452,7 @@ isert_login_recv_done(struct ib_cq *cq, struct ib_wc *wc) { struct isert_conn *isert_conn = wc->qp->qp_context; - struct ib_device *ib_dev = isert_conn->cm_id->device; + struct ib_device *ib_dev = isert_conn->device->ib_device; if (unlikely(wc->status != IB_WC_SUCCESS)) { isert_print_wc(wc, "login recv");I'll test also this one-liner fix as soon as I can. But I can say that I'm pretty sure it will work as well, because all the previous NULL pointer dereferences that we've got in the past happened all 100% in isert_login_recv_done(). The other cases are probably a safe precaution, but they can't really happen.
Agree, I'd prefer to start with a surgical fix before moving forward.
