ath.git patches for v6.12 This is once again a fairly light pull request since ath12k is still working on MLO-related changes, and the other drivers are mostly in maintenance mode. ath12k * Fix a frame-larger-than warning seen with debug builds * Fix flex-array-member-not-at-end warnings ath11k * Fix flex-array-member-not-at-end warnings ath9k * Fix a syzbot-reported issue on USB-based devices

wifi: mac80211: handle ieee80211_radar_detected() for MLO

2024-09-06T11:01:05Z

Currently DFS works under assumption there could be only one channel context in the hardware. Hence, drivers just calls the function ieee80211_radar_detected() passing the hardware structure. However, with MLO, this obviously will not work since number of channel contexts will be more than one and hence drivers would need to pass the channel information as well on which the radar is detected. Also, when radar is detected in one of the links, other link's CAC should not be cancelled. Hence, in order to support DFS with MLO, do the following changes - * Add channel context conf pointer as an argument to the function ieee80211_radar_detected(). During MLO, drivers would have to pass on which channel context conf radar is detected. Otherwise, drivers could just pass NULL. * ieee80211_radar_detected() will iterate over all channel contexts present and * if channel context conf is passed, only mark that as radar detected * if NULL is passed, then mark all channel contexts as radar detected * Then as usual, schedule the radar detected work. * In the worker, go over all the contexts again and for all such context which is marked with radar detected, cancel the ongoing CAC by calling ieee80211_dfs_cac_cancel() and then notify cfg80211 via cfg80211_radar_event(). * To cancel the CAC, pass the channel context as well where radar is detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is canceled only on the links using the provided context, leaving other links unaffected. This would also help in scenarios where there is split phy 5 GHz radio, which is capable of DFS channels in both lower and upper band. In this case, simultaneous radars can be detected.

wifi: ath12k: Avoid -Wflex-array-member-not-at-end warnings

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Move the conflicting declaration to the end of the structure. Notice that `struct ieee80211_chanctx_conf` is a flexible structure --a structure that contains a flexible-array member. Also, remove an unused structure.

Revert "wifi: ath11k: support hibernation"

This reverts commit 166a490f59ac10340ee5330e51c15188ce2a7f8f. There are several reports that this commit breaks system suspend on some specific Lenovo platforms. Since there is no fix available, for now revert this commit to make suspend work again on those platforms.

wifi: ath11k: fix NULL pointer dereference in ath11k_mac_get_eirp_power()

2024-08-22T11:16:51Z

Commit 39dc8b8ea387 ("wifi: mac80211: pass parsed TPE data to drivers") breaks ath11k, leading to kernel crash: BUG: kernel NULL pointer dereference, address: 0000000000000018 RIP: 0010:ath11k_mac_get_eirp_power.isra.0+0x5b/0x80 [ath11k] Call Trace: ath11k_mac_fill_reg_tpc_info+0x3d6/0x800 [ath11k] ath11k_mac_vdev_start_restart+0x412/0x4d0 [ath11k] ath11k_mac_op_sta_state+0x7bc/0xbb0 [ath11k] drv_sta_state+0xf1/0x5f0 [mac80211] sta_info_insert_rcu+0x28d/0x530 [mac80211] sta_info_insert+0xf/0x20 [mac80211] ieee80211_prep_connection+0x3b4/0x4c0 [mac80211] ieee80211_mgd_auth+0x363/0x600 [mac80211] The issue scenario is, AP advertises power spectral density (PSD) values in its transmit power envelope (TPE) IE and supports 160 MHz bandwidth in 6 GHz. When connecting to this AP, in ath11k_mac_parse_tx_pwr_env(), the local variable psd is true and then reg_tpc_info.num_pwr_levels is set to 8 due to 160 MHz bandwidth. Note here ath11k fails to set reg_tpc_info.is_psd_power as TRUE due to above commit. Then in ath11k_mac_fill_reg_tpc_info(), for each of the 8 power levels, for a PSD channel, ath11k_mac_get_psd_channel() is expected to be called to get required information. However due to invalid reg_tpc_info.is_psd_power, it is ath11k_mac_get_eirp_power() that gets called and passed with pwr_lvl_idx as one of the arguments. Note this function implicitly requires pwr_lvl_idx to be no more than 3. So when pwr_lvl_idx is larger than that ath11k_mac_get_seg_freq() returns invalid center frequency, with which as the input ieee80211_get_channel() returns NULL, then kernel crashes due to NULL pointer dereference. Fix it by setting reg_tpc_info.is_psd_power properly.
