Technical Description
In the Linux kernel, the following vulnerability has been resolved:
ath11k: Fix frames flush failure caused by deadlock
We are seeing below warnings:
kernel: [25393.301506] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421509] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0
kernel: [25398.421831] ath11k_pci 0000:01:00.0: dropping mgmt frame for vdev 0, is_started 0
this means ath11k fails to flush mgmt. frames because wmi_mgmt_tx_work
has no chance to run in 5 seconds.
By setting /proc/sys/kernel/hung_task_timeout_secs to 20 and increasing
ATH11K_FLUSH_TIMEOUT to 50 we get below warnings:
kernel: [ 120.763160] INFO: task wpa_supplicant:924 blocked for more than 20 seconds.
kernel: [ 120.763169] Not tainted 5.10.90 #12
