Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: Fix duplicated reported IW_CM_EVENT_CONNECT_REPLY event If siw_recv_mpa_rr returns -EAGAIN, it means that the MPA reply hasn't been received completely, and should not report IW_CM_EVENT_CONNECT_REPLY in this case. This may trigger a call trace in iw_cm. A simple way to trigger this: server: ib_send_lat client: ib_send_lat -R <server_ip> The call trace looks like this: kernel BUG at drivers/infiniband/core/iwcm.c:894! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <...> Workqueue: iw_cm_wq cm_work_handler [iw_cm] Call Trace: <TASK> cm_work_handler+0x1dd/0x370 [iw_cm] process_one_work+0x1e2/0x3b0 worker_thread+0x49/0x2e0 ? rescuer_thread+0x370/0x370 kthread+0xe5/0x110 ? kthread_complete_and_exit+0x20/0x20 ret_from_fork+0x1f/0x30 </TASK>
