wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash Currently, we encounter the following kernel call trace when a firmware crash occurs. This happens because the host sends WMI commands to the firmware while it is in recovery, causing the commands to fail and resulting in the kernel call trace. Set the ATH12K_FLAG_CRASH_FLUSH and ATH12K_FLAG_RECOVERY flags when the host driver receives the firmware crash notification from MHI. This prevents sending WMI commands to the firmware during recovery. Call Trace: dump_stack_lvl+0x75/0xc0 register_lock_class+0x6be/0x7a0 ? __lock_acquire+0x644/0x19a0 __lock_acquire+0x95/0x19a0 lock_acquire+0x265/0x310 ? ath12k_ce_send+0xa2/0x210 [ath12k] ? find_held_lock+0x34/0xa0 ? ath12k_ce_send+0x56/0x210 [ath12k] _raw_spin_lock_bh+0x33/0x70 ? ath12k_ce_send+0xa2/0x210 [ath12k] ath12k_ce_send+0xa2/0x210 [ath12k] ath12k_htc_send+0x178/0x390 [ath12k] ath12k_wmi_cmd_send_nowait+0x76/0xa0 [ath12k] ath12k_wmi_cmd_send+0x62/0x190 [ath12k] ath12k_wmi_pdev_bss_chan_info_request+0x62/0xc0 [ath1 ath12k_mac_op_get_survey+0x2be/0x310 [ath12k] ieee80211_dump_survey+0x99/0x240 [mac80211] nl80211_dump_survey+0xe7/0x470 [cfg80211] ? kmalloc_reserve+0x59/0xf0 genl_dumpit+0x24/0x70 netlink_dump+0x177/0x360 __netlink_dump_start+0x206/0x280 genl_family_rcv_msg_dumpit.isra.22+0x8a/0xe0 ? genl_family_rcv_msg_attrs_parse.isra.23+0xe0/0xe0 ? genl_op_lock.part.12+0x10/0x10 ? genl_d
