2022-09-15wifi: mt76: mt7921e: fix crash in chip reset failDeren Wu1-1/+1
commit fa3fbe64037839f448dc569212bafc5a495d8219 upstream. In case of drv own fail in reset, we may need to run mac_reset several times. The sequence would trigger system crash as the log below. Because we do not re-enable/schedule "tx_napi" before disable it again, the process would keep waiting for state change in napi_diable(). To avoid the problem and keep status synchronize for each run, goto final resource handling if drv own failed.

commit 9d958b60ebc2434f2b7eae83d77849e22d1059eb upstream. Due to AP stop improperly, mt7921 driver would face random command timeout by chip fw problem. Migrate AP start/stop process to .start_ap/.stop_ap and congiure BSS network settings in both hooks. The new flow is shown below. * AP start .start_ap() configure BSS network resource set BSS to connected state .bss_info_changed() enable fw beacon offload * AP stop .bss_info_changed() disable fw beacon offload (skip this command) .stop_ap() set BSS to disconnected state (beacon offload disabled automatically) destroy BSS network resource Fixes: 116c69603b01 ("mt76: mt7921: Add AP mode support") Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Deren Wu <deren.wu@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

dev_coredumpm" commit 38a523a2946d3a0961d141d477a1ee2b1f3bdbb1 upstream. This reverts commit 77515ebaf01920e2db49e04672ef669a7c2907f2 as it causes build problems in linux-next. It needs to be reintroduced in a way that can allow the api to evolve and not require a "flag day" to catch all users.

[ Upstream commit aac86cebb4a09e3fa2c07589f79f7d0e07e8c9a4 ] For some reason, mt7615 reacts badly to repeatedly enabling/disabling the radar detector without also switching the channel. This results in very bad throughput on DFS channels, because hw->conf.radar_enabled can get toggled a few times after CAC ends.

2022-05-16mac80211: extend current rate control tx status APIJonas Jelonek1-3/+2
This patch adds the new struct ieee80211_rate_status and replaces 'struct rate_info *rate' in ieee80211_tx_status with pointer and length annotation. The struct ieee80211_rate_status allows to: (1) receive tx power status feedback for transmit power control (TPC) per packet or packet retry (2) dynamic mapping of wifi chip specific multi-rate retry (mrr) chains with different lengths (3) increase the limit of annotatable rate indices to support IEEE802.11ac rate sets and beyond ieee80211_tx_info, control and status buffer, and ieee80211_tx_rate cannot be used to achieve these goals due to fixed size limitations. Our new struct contains a struct rate_info to annotate the rate that was used, retry count of the rate and tx power. It is intended for all information related to RC and TPC that needs to be passed from driver to mac80211 and its RC/TPC algorithms like Minstrel_HT. It corresponds to one stage in an mrr. Multiple subsequent instances of this struct can be included in struct ieee80211_tx_status via a pointer and a length variable. Those instances can be allocated on-stack. The former reference to a single instance of struct rate_info is replaced with our new annotation. An extension is introduced to struct ieee80211_hw. There are two new members called 'tx_power_levels' and 'max_txpwr_levels_idx' acting as a tx power level table. When a wifi device is registered, the driver shall supply all supported power levels in this list. This allows to support several quirks like differing power steps in power level ranges or alike. TPC can use this for algorithm and thus be designed more abstract instead of handling all possible step widths individually. Further mandatory changes in status.c, mt76 and ath11k drivers due to the removal of 'struct rate_info *rate' are also included. status.c already uses the information in ieee80211_tx_status->rate in radiotap, this is now changed to use ieee80211_rate_status->rate_idx. mt76 driver already uses struct rate_info to pass the tx rate to status path. The new members of the ieee80211_tx_status are set to NULL and 0 because the previously passed rate is not relevant to rate control and accurate information is passed via tx_info->status.rates. For ath11k, the txrate can be passed via this struct because ath11k uses firmware RC and thus the information does not interfere with software RC.

2022-05-13mt76: fix tx status related use-after-free race on station removalFelix Fietkau2-1/+3
There is a small race window where ongoing tx activity can lead to a skb getting added to the status tracking idr after that idr has already been cleaned up, which will keep the wcid linked in the status poll list. Fix this by only adding status skbs if the wcid pointer is still assigned in dev->wcid, which gets cleared early by mt76_sta_pre_rcu_remove Fixes: bd1e3e7b693c ("mt76: introduce packet_id idr") Tested-by: Ben Greear <greearb@candelatech.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
