2023-09-30wifi: mt76: mt7603: add missing register initialization for MT7628Felix Fietkau1-0/+7

2023-09-30wifi: mt76: mt7603: improve stuck beacon handlingFelix Fietkau2-21/+60
Before preparing the new beacon, check the queue status, flush out all previous beacons and buffered multicast packets, then (if necessary) try to recover more gracefully from a stuck beacon condition by making a less invasive attempt at getting the MAC un-stuck.

2023-09-30wifi: mt76: mt7603: improve watchdog reset reliablityFelix Fietkau1-17/+12
Only trigger PSE reset if PSE was stuck, otherwise it can cause DMA issues. Trigger the PSE reset while DMA is fully stopped in order to improve reliabilty. Fixes: c8846e101502 ("mt76: add driver for MT7603E and MT7628/7688") Signed-off-by: Felix Fietkau <nbd@nbd.name>
2023-09-30wifi: mt76: mt7603: rework/fix rx pse hang checkFelix Fietkau2-7/+18
It turns out that the code in mt7603_rx_pse_busy() does not detect actual hardware hangs, it only checks for busy conditions in PSE. A reset should only be performed if these conditions are true and if there is no rx activity as well. Reset the counter whenever a rx interrupt occurs. In order to also deal with a fully loaded CPU that leaves interrupts disabled with continuous NAPI polling, also check for pending rx interrupts in the function itself.

2023-09-28wifi: rtw89: pause/proceed MCC for ROC and HW scanZong-Zhe Yang5-2/+84
During (TDMA-based) MCC (multi-channel concurrency), the below two cases might not have a good behavior on channel usage. * ROC (remain on channel) * HW scan So, we tend to separate them from MCC. The two cases would expect to operate the channel to which they want. However, during MCC, channels are scheduled by FW MCC state mechanism. So, channels cannot be controlled explicitly. To avoid the two cases from operating wrong channels with chance, we pause MCC (essentially stop FW MCC) once the two cases are coming. And then, we proceed MCC again (essentially restart FW MCC) once the two cases finish.

2023-09-28wifi: rtw89: mcc: fix NoA start time when GO is auxiliaryZong-Zhe Yang1-0/+4
Under TDMA-based MCC (multi-channel concurrency), there are two roles, reference and auxiliary. We arrange MCC timeline based on time domain of reference role. Then, we calculate NoA start time according to MCC timeline. Besides, when MCC runs GO+STA mode, we plan an offset between GO time domain and STA time domain to make their TBTTs have a time gap. However, if GO is auxiliary role instead of reference role, NoA start time is described by STA time domain instead of GO time domain. To fix this, we apply the offset mentioned above to NoA start time to convert time domain from STA to GO.

2023-09-28wifi: ath12k: add msdu_end structure for WCN7850Kang Yang2-20/+83
WCN7850 and QCN9274 currently use the same structure rx_msdu_end_qcn9274 for msdu_end. But content of msdu_end on WCN7850 is different from that of QCN9274. Need to update it for WCN7850, otherwise will get the wrong values when using it. For example, TID is no longer in WCN7850's msdu_end. But ath12k_dp_rx_process_err() and ath12k_dp_rx_process_wbm_err() still get TID from msdu_end. So an uncertain value will be used in these two functions on WCN7850. Therefore, add new structure rx_msdu_end_wcn7850 for WCN7850.

2023-09-28wifi: ath12k: enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850Wen Gong1-0/+5
Currently mac80211 will send 3 scan request for each scan of WCN7850, they are 2.4 GHz/5 GHz/6 GHz band scan. Firmware of WCN7850 will cache the RNR IE(Reduced Neighbor Report element) which exist in the beacon of 2.4 GHz/5 GHz of the AP which is co-located with 6 GHz, and then use the cache to scan in 6 GHz band scan if the 6 GHz scan is in the same scan with the 2.4 GHz/5 GHz band, this will helpful to search more AP of 6 GHz. Also it will decrease the time cost of scan because firmware will use dual-band scan for the 2.4 GHz/5 GHz, it means the 2.4 GHz and 5 GHz scans are doing simultaneously. Set the flag IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS for WCN7850 since it supports 2.4 GHz/5 GHz/6 GHz in a single wiphy/ieee80211_hw. This does not impact QCN9274, because it is not single_phy, so does not have 2.4 GHz/5 GHz/6 GHz in the same wiphy, then it does not match the condition and then IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS will not set for QCN9274.

The firmware will cancel the current scan after receiving WMI_SCAN_CHAN_LIST_CMDID which is used for the new channel list, and the state of ath12k is ATH12K_SCAN_RUNNING, then ath12k_get_ar_on_scan_abort() returns NULL and ath12k_scan_event() returns at this point and does not indicate scan completion to mac80211.

ATH12K_SCAN_STARTING state Scan failure can not be recovered from when running a loop of the following steps: 1. run scan: "iw wlan scan". 2. run command: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0/simulate_fw_crash immediately after step 1. result: scan failed and can not recover even when wlan recovery succeeds: command failed: Device or resource busy (-16) reason: When scan arrives, WMI_START_SCAN_CMDID is sent to the firmware and function ath12k_mac_op_hw_scan() returns, then simulate_fw_crash arrives and the scan started event does not arrive, and then it starts to do recovery of wlan. __ath12k_mac_scan_finish() which is called from ath12k_core_halt() is one step of recovery, it will not call ieee80211_scan_completed() by logic currently because the scan state is ATH12K_SCAN_STARTING. Thus it leads the scan not being completed in mac80211, and leads all consecutive scans failing with -EBUSY in nl80211_trigger_scan even after wlan recovery success. Indicate scan complete with aborted flag to mac80211 for ATH12K_SCAN_STARTING to allow recovery from scan failed with "Device or resource busy (-16)" after wlan recovery.

2023-09-25wifi: iwlwifi: pcie: (re-)assign BAR0 on driver bindJohannes Berg1-0/+9
There's a race with runtime PM getting enabled by userspace: - we rescan the PCI bus - this creates the new PCI device including its sysfs representation - udev sees the new device, and the (OS-specific?) scripting enables runtime PM by writing to power/control; this can happen _before_ the next step - this will runtime-suspend the device which saves the config space, including the BAR0 that wasn't assigned yet - the bus rescan assigns resources to the devices and writes them to the config space of the device (but not the runtime-pm saved copy) - the driver binds and this disallows runtime PM, so the device is resumed, restoring the (incomplete!) config space - the driver cannot work due to BAR0 not being configured Fixing the actual race is hard and deep in the PCI layer, though probably should be done for upstream as well; perhaps runtime PM should only be allowed after resource assignment, or some other TBD way. Work around this in the driver for now by simply (re-)assigning BAR0 when the driver initializes, if it's unset.

If the firmware has this capability, read BIOS configuration data in function 4 using ACPI API and send GRP_REGULATORY_LARI_CONFIG_CHANGE_CMD to the firmware.

2023-09-25wifi: iwlwifi: mvm: support set_antenna()Emmanuel Grumbach9-27/+148
set_antenna() is supported only when the device is not started in mac80211 which translates to the firmware not being loaded in iwlwifi. The tricky part is that iwlwifi populates the sband data during its boot and doesn't touch this data afterwards, but if the antenna settings forbid MIMO, we need to update the sband data. Rework the nvm parsing code to allow to get an existing nvm_data and modify the sband with additional constraints (tx / rx chains masks).

2023-09-25wifi: cfg80211: report per-link errors during associationBenjamin Berg2-6/+47
When one of the links (other than the assoc_link) is misconfigured and cannot work the association will fail. However, userspace was not able to tell that the operation only failed because of a problem with one of the links. Fix this, by allowing the driver to set a per-link error code and reporting the (first) offending link by setting the bad_attr accordingly. This only allows us to report the first error, but that is sufficient for userspace to e.g. remove the offending link and retry.

2023-09-25wifi: mac80211: support antenna control in injectionJohannes Berg3-1/+21
Support antenna control for injection by parsing the antenna radiotap field (which may be presented multiple times) and telling the driver about the resulting antenna bitmap. Of course there's no guarantee the driver will actually honour this, just like any other injection control. If misconfigured, i.e. the injected HT/VHT MCS needs more chains than antennas are configured, the bitmap is reset to zero, indicating no selection. For now this is only set up for two anntenas so we keep more free bits, but that can be trivially extended if any driver implements support for it that can deal with hardware with more antennas.
