In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/sec - don't sleep when in softirq When kunpeng920 encryption driver is used to deencrypt and decrypt packets during the softirq, it is not allowed to use mutex lock. The kernel will report the following error: BUG: scheduling while atomic: swapper/57/0/0x00000300 Call trace: dump_backtrace+0x0/0x1e4 show_stack+0x20/0x2c dump_stack+0xd8/0x140 __schedule_bug+0x68/0x80 __schedule+0x728/0x840 schedule+0x50/0xe0 schedule_preempt_disabled+0x18/0x24 __mutex_lock.constprop.0+0x594/0x5dc __mutex_lock_slowpath+0x1c/0x30 mutex_lock+0x50/0x60 sec_request_init+0x8c/0x1a0 [hisi_sec2] sec_process+0x28/0x1ac [hisi_sec2] sec_skcipher_crypto+0xf4/0x1d4 [hisi_sec2] sec_skcipher_encrypt+0x1c/0x30 [hisi_sec2] crypto_skcipher_encrypt+0x2c/0x40 crypto_authenc_encrypt+0xc8/0xfc [authenc] crypto_aead_encrypt+0x2c/0x40 echainiv_encrypt+0x144/0x1a0 [echainiv] crypto_aead_encrypt+0x2c/0x40 esp_output_tail+0x348/0x5c0 [esp4] esp_output+0x120/0x19c [esp4] xfrm_output_one+0x25c/0x4d4 xfrm_output_resume+0x6c/0x1fc xfrm_output+0xac/0x3c0 xfrm4_output+0x64/0x130 ip_build_and_send_pkt+0x158/0x20c tcp_v4_send_synack+0xdc/0x1f0 tcp_conn_request+0x7d0/0x994 tcp_v4_conn_request+0x58/0x6c tcp_v6_conn_request+0xf0/0x100 tcp_rcv_state_process+0x1cc/0xd60 tcp_v4_do_rcv+0x10c/0x250 tcp_v4_rcv+0xfc4/0x10a4 ip_protocol_deliver_rcu+0xf4/0x200 ip_local_deliver_finish+0x58/0x70 ip_local_deliver+0x68/0x120 ip_sublist_rcv_finish+0x70/0x94 ip_list_rcv_finish.constprop.0+0x17c/0x1d0 ip_sublist_rcv+0x40/0xb0 ip_list_rcv+0x140/0x1dc __netif_receive_skb_list_core+0x154/0x28c __netif_receive_skb_list+0x120/0x1a0 netif_receive_skb_list_internal+0xe4/0x1f0 napi_complete_done+0x70/0x1f0 gro_cell_poll+0x9c/0xb0 napi_poll+0xcc/0x264 net_rx_action+0xd4/0x21c __do_softirq+0x130/0x358 irq_exit+0x11c/0x13c __handle_domain_irq+0x88/0xf0 gic_handle_irq+0x78/0x2c0 el1_irq+0xb8/0x140 arch_cpu_idle+0x18/0x40 default_idle_call+0x5c/0x1c0 cpuidle_idl
