Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix sleeping-in-atomic in ath11k_mac_op_set_bitrate_mask()
ath11k_mac_disable_peer_fixed_rate() is passed as the iterator to
ieee80211_iterate_stations_atomic(). Note in this case the iterator is
required to be atomic, however ath11k_mac_disable_peer_fixed_rate() does
not follow it as it might sleep. Consequently below warning is seen:
BUG: sleeping function called from invalid context at wmi.c:304
Call Trace:
<TASK>
dump_stack_lvl
__might_resched.cold
ath11k_wmi_cmd_send
ath11k_wmi_set_peer_param
ath11k_mac_disable_peer_fixed_rate
ieee80211_iterate_stations_atomic
ath11k_mac_op_set_bitrate_mask.cold
Change to ieee80211_iterate_stations_mtx() to fix this issue.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
