Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix WQ_MEM_RECLAIM warning When sunrpc is used, if a reset triggered, our wq may lead the following trace: workqueue: WQ_MEM_RECLAIM xprtiod:xprt_rdma_connect_worker [rpcrdma] is flushing !WQ_MEM_RECLAIM hns_roce_irq_workq:flush_work_handle [hns_roce_hw_v2] WARNING: CPU: 0 PID: 8250 at kernel/workqueue.c:2644 check_flush_dependency+0xe0/0x144 Call trace: check_flush_dependency+0xe0/0x144 start_flush_work.constprop.0+0x1d0/0x2f0 __flush_work.isra.0+0x40/0xb0 flush_work+0x14/0x30 hns_roce_v2_destroy_qp+0xac/0x1e0 [hns_roce_hw_v2] ib_destroy_qp_user+0x9c/0x2b4 rdma_destroy_qp+0x34/0xb0 rpcrdma_ep_destroy+0x28/0xcc [rpcrdma] rpcrdma_ep_put+0x74/0xb4 [rpcrdma] rpcrdma_xprt_disconnect+0x1d8/0x260 [rpcrdma] xprt_rdma_connect_worker+0xc0/0x120 [rpcrdma] process_one_work+0x1cc/0x4d0 worker_thread+0x154/0x414 kthread+0x104/0x144 ret_from_fork+0x10/0x18 Since QP destruction frees memory, this wq should have the WQ_MEM_RECLAIM.
