Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix warning in poll cq direct mode CQs allocated by ib_alloc_cq() always have a comp_handler. Though in direct mode this handler is never expected to be called, it is still called when the driver is reset, triggering the following WARN_ONCE(): Call trace: ib_cq_completion_direct+0x38/0x60 hns_roce_cq_completion+0x54/0x90 (hns_roce_hw_v2] hns_roce_handle_device_err+Ox1c8/0x340 [hns_roce_hw_v2] hns_roce_hw_v2_uninit_instance.constprop.0+0x34/0x70 [hns_roce_hw_v2] hns_roce_hw_v2_reset_notify+0xc4/0xe0 [hns_roce_hw_v2] hclge_notify_roce_client+0x60/0xbc [hclge] hclge_reset_rebuild+0x48/0x34c [hclge] hclge_reset_subtask+0xcc/0xec [hclge] hclge_reset_service_task+0x80/0x160 [hclge] hclge_service_task+0x50/0x80 (hclge] process_one_work+0x1cc/0x4d0 worker_thread+0x154/0x414 kthread+0x104/0x144 ret_from_fork+0x10/0x18
