In the Linux kernel, the following vulnerability has been resolved:net: hns3: don't auto enable misc vectorCurrently, there is a time window between misc irq enabledand service task inited. If an interrupte is reported atthis time, it will cause warning like below:[ 16.324639] Call trace:[ 16.324641] __queue_delayed_work+0xb8/0xe0[ 16.324643] mod_delayed_work_on+0x78/0xd0[ 16.324655] hclge_errhand_task_schedule+0x58/0x90 [hclge][ 16.324662] hclge_misc_irq_handle+0x168/0x240 [hclge][ 16.324666] __handle_irq_event_percpu+0x64/0x1e0[ 16.324667] handle_irq_event+0x80/0x170[ 16.324670] handle_fasteoi_edge_irq+0x110/0x2bc[ 16.324671] __handle_domain_irq+0x84/0xfc[ 16.324673] gic_handle_irq+0x88/0x2c0[ 16.324674] el1_irq+0xb8/0x140[ 16.324677] arch_cpu_idle+0x18/0x40[ 16.324679] default_idle_call+0x5c/0x1bc[ 16.324682] cpuidle_idle_call+0x18c/0x1c4[ 16.324684] do_idle+0x174/0x17c[ 16.324685] cpu_startup_entry+0x30/0x6c[ 16.324687] secondary_start_kernel+0x1a4/0x280[ 16.324688] ---[ end trace 6aa0bff672a964aa ]---So don't auto enable misc vector when request irq..
