wifi: ath11k: clear initialized flag for deinit-ed srng lists
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: clear initialized flag for deinit-ed srng lists In a number of cases we see kernel panics on resume due to ath11k kernel page fault, which happens under the following circumstances: 1) First ath11k_hal_dump_srng_stats() call Last interrupt received for each group: ath11k_pci 0000:01:00.0: group_id 0 22511ms before ath11k_pci 0000:01:00.0: group_id 1 14440788ms before [..] ath11k_pci 0000:01:00.0: failed to receive control response completion, polling.. ath11k_pci 0000:01:00.0: Service connect timeout ath11k_pci 0000:01:00.0: failed to connect to HTT: -110 ath11k_pci 0000:01:00.0: failed to start core: -110 ath11k_pci 0000:01:00.0: firmware crashed: MHI_CB_EE_RDDM ath11k_pci 0000:01:00.0: already resetting count 2 ath11k_pci 0000:01:00.0: failed to wait wlan mode request (mode 4): -110 ath11k_pci 0000:01:00.0: qmi failed to send wlan mode off: -110 ath11k_pci 0000:01:00.0: failed to reconfigure driver on crash recovery [..] 2) At this point reconfiguration fails (we have 2 resets) and ath11k_core_reconfigure_on_crash() calls ath11k_hal_srng_deinit() which destroys srng lists. However, it does not reset per-list ->initialized flag. 3) Second ath11k_hal_dump_srng_stats() call sees stale ->initialized flag and attempts to dump srng stats: Last interrupt received for each group: ath11k_pci 0000:01:00.0: group_id 0 66785ms before ath11k_pci 0000:01:00.0: group_id 1 14485062ms before ath11k_pci 0000:01:00.0: group_id 2 14485062ms before ath11k_pci 0000:01:00.0: group_id 3 14485062ms before ath11k_pci 0000:01:00.0: group_id 4 14780845ms before ath11k_pci 0000:01:00.0: group_id 5 14780845ms before ath11k_pci 0000:01:00.0: group_id 6 14485062ms before ath11k_pci 0000:01:00.0: group_id 7 66814ms before ath11k_pci 0000:01:00.0: group_id 8 68997ms before ath11k_pci 0000:01:00.0: group_id 9 67588ms before ath11k_pci 0000:01:00.0: group_id 10 69511ms before BUG: unable to handle page fault for address: ffffa007404eb010 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 100000067 P4D 100000067 PUD 10022d067 PMD 100b01067 PTE 0 Oops: 0000 [#1] PREEMPT SMP NOPTI RIP: 0010:ath11k_hal_dump_srng_stats+0x2b4/0x3b0 [ath11k] Call Trace: <TASK> ? __die_body+0xae/0xb0 ? page_fault_oops+0x381/0x3e0 ? exc_page_fault+0x69/0xa0 ? asm_exc_page_fault+0x22/0x30 ? ath11k_hal_dump_srng_stats+0x2b4/0x3b0 [ath11k (HASH:6cea 4)] ath11k_qmi_driver_event_work+0xbd/0x1050 [ath11k (HASH:6cea 4)] worker_thread+0x389/0x930 kthread+0x149/0x170 Clear per-list ->initialized flag in ath11k_hal_srng_deinit().
