In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: add srng->lock for ath11k_hal_srng_* in monitor mode ath11k_hal_srng_* should be used with srng->lock to protect srng data. For ath11k_dp_rx_mon_dest_process() and ath11k_dp_full_mon_process_rx(), they use ath11k_hal_srng_* for many times but never call srng->lock. So when running (full) monitor mode, warning will occur: RIP: 0010:ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k] Call Trace: ? ath11k_hal_srng_dst_peek+0x18/0x30 [ath11k] ath11k_dp_rx_process_mon_status+0xc45/0x1190 [ath11k] ? idr_alloc_u32+0x97/0xd0 ath11k_dp_rx_process_mon_rings+0x32a/0x550 [ath11k] ath11k_dp_service_srng+0x289/0x5a0 [ath11k] ath11k_pcic_ext_grp_napi_poll+0x30/0xd0 [ath11k] __napi_poll+0x30/0x1f0 net_rx_action+0x198/0x320 __do_softirq+0xdd/0x319 So add srng->lock for them to avoid such warnings. Inorder to fetch the srng->lock, should change srng's definition from 'void' to 'struct hal_srng'. And initialize them elsewhere to prevent one line of code from being too long. This is consistent with other ring process functions, such as ath11k_dp_process_rx().
