Chao Leng a7aa5d578f nvme-rdma: fix crash when connect rejected ... [ Upstream commit 43efdb8e87 ] A crash can happened when a connect is rejected. The host establishes the connection after received ConnectReply, and then continues to send the fabrics Connect command. If the controller does not receive the ReadyToUse capsule, host may receive a ConnectReject reply. Call nvme_rdma_destroy_queue_ib after the host received the RDMA_CM_EVENT_REJECTED event. Then when the fabrics Connect command times out, nvme_rdma_timeout calls nvme_rdma_complete_rq to fail the request. A crash happenes due to use after free in nvme_rdma_complete_rq. nvme_rdma_destroy_queue_ib is redundant when handling the RDMA_CM_EVENT_REJECTED event as nvme_rdma_destroy_queue_ib is already called in connection failure handler.
