Aloka originally suggested that puncturing should be part of the chandef, so that it's treated correctly. At the time, I disagreed and it ended up not part of the chandef, but I've now realized that this was wrong. Even for clients, the RX, and perhaps more importantly, CCA configuration needs to take puncturing into account. Move puncturing into the chandef, and adjust all the code accordingly. Also add a few tests for puncturing in chandef compatibility checking.

2024-02-08wifi: iwlwifi: mvm: fix a crash when we run out of stationsEmmanuel Grumbach2-0/+7
A DoS tool that injects loads of authentication frames made our AP crash. The iwl_mvm_is_dup() function couldn't find the per-queue dup_data which was not allocated. The root cause for that is that we ran out of stations in the firmware and we didn't really add the station to the firmware, yet we didn't return an error to mac80211. Mac80211 was thinking that we have the station and because of that, sta_info::uploaded was set to 1. This allowed ieee80211_find_sta_by_ifaddr() to return a valid station object, but that ieee80211_sta didn't have any iwl_mvm_sta object initialized and that caused the crash mentioned earlier when we got Rx on that station.

2024-02-08iwlwifi: mvm: Use for_each_thermal_trip() for walking trip pointsRafael J. Wysocki1-15/+25
The code walking trip points in iwl_mvm_send_temp_report_ths_cmd() reads the trip table passed to thermal_zone_device_register_with_trips() in order to get the current trip temperatures, but this is not guaranteed to work in the future, because the thermal zone will store trip points information internally. For this reason, make iwl_mvm_send_temp_report_ths_cmd() use for_each_thermal_trip() as appropriate for walking trip points in a given thermal zone. No intentional functional impact, but it is requisite for future thermal core improvements. Signed-off-by: Rafael J. Wysocki <[email protected]> Acked-by: Miri Korenblit <[email protected]>

The trip table in iwl_mvm_thermal_zone_register() is populated after passing it to thermal_zone_device_register_with_trips(), so it may be accessed (for instance, via sysfs) before it is ready.

Note that the iwl_mvm_send_temp_report_ths_cmd() code populating fw_trips_index[] is questionable, because it accesses a trips table of a thermal zone directly, which is not guaranteed to work in the future.

2024-02-08wifi: iwlwifi: mvm: use correct address 3 in A-MSDUDaniel Gabay1-10/+59
As described in IEEE sta 802.11-2020, table 9-30 (Address field contents), A-MSDU address 3 should contain the BSSID address. In TX_CMD we copy the MAC header from skb, and skb address 3 holds the destination address, but it may not be identical to the BSSID. Using the wrong destination address appears to work with (most) receivers without MLO, but in MLO some devices are checking for it carefully, perhaps as a consequence of link to MLD address translation. Replace address 3 in the TX_CMD MAC header with the correct address while retaining the skb address 3 unchanged. This ensures that skb address 3 will be utilized later for constructing the A-MSDU subframes. Note that we fill in the MLD address, but the firmware will do the necessary translation to link address after encryption.

2024-02-08wifi: mac80211: introduce 'channel request'Johannes Berg7-26/+26
For channel contexts, mac80211 currently uses the cfg80211 chandef struct (control channel, center freq(s), width) to define towards drivers and internally how these behave. In fact, there are _two_ such structs used, where the min_def can reduce bandwidth according to the stations connected. Unfortunately, with EHT this is longer be sufficient, at least not for all hardware. EHT requires that non-AP STAs that are connected to an AP with a lower bandwidth than it (the AP) advertises (e.g. 160 MHz STA connected to 320 MHz AP) still be able to receive downlink OFDMA and respond to trigger frames for uplink OFDMA that specify the position and bandwidth for the non-AP STA relative to the channel the AP is using. Therefore, they need to be aware of this, and at least for some hardware (e.g. Intel) this awareness is in the hardware. As a result, use of the "same" channel may need to be split over two channel contexts where they differ by the AP being used. As a first step, introduce a concept of a channel request ('chanreq') for each interface, to control the context it requests. This step does nothing but reorganise the code, so that later the AP's chandef can be added to the request in order to handle the EHT case described above.

2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg3-0/+12
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

2024-02-02wifi: iwlwifi: simplify getting DSM from ACPIMiri Korenblit4-85/+73
As DSMs are going to be read from UEFI too, we need a unified API to get DSMs for both ACPI and UEFI. The difference in getting DSM in each one of these methods (ACPI, UEFI) is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM values (8 or 32 for ACPI, 32 for UEFI). Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which determines the GUID, revision (these two are the same for all WiFi DSMs), and size (based on a func-to-size mapping) internally.

New tx devices may have issues sending NDPs from the host. Send a CQM event instead. If the AP is really gone, we will get a beacon loss and disconnect.

2024-02-02wifi: iwlwifi: exit eSR only after the FW doesMiri Korenblit1-3/+3
Currently the driver exits eSR by calling iwl_mvm_esr_mode_inactive() before updating the FW (by deactivating one of the links), and therefore before sending the EML frame notifying that we are no longer in eSR. This is wrong for several reasons: 1. The driver sends SMPS activation frames when we are still in eSR and SMPS should be disabled when in eSR 2. The driver restores RLC configuration as it was before eSR entering, and RLC command shouldn't be sent in eSR Fix this by calling iwl_mvm_esr_mode_inactive() after FW update Fixes: 12bacfc2c065 ("wifi: iwlwifi: handle eSR transitions") Signed-off-by: Miri Korenblit <[email protected]> Reviewed-by: Ilan Peer <[email protected]> Reviewed-by: Gregory Greenman <[email protected]> Link: https://msgid.link/20240201155157.d8d9dc277d4e.Ib5aee0fd05e35b1da7f18753eb3c8fa0a3f872f3@changeid Signed-off-by: Johannes Berg <[email protected]>

2024-02-02wifi: iwlwifi: separate TAS 'read-from-BIOS' and 'send-to-FW' flowsMiri Korenblit6-53/+62
Currently the TAS 'read-from-BIOS' flow receives the command struct and the version of it as read from FW TLVs, and fills the command accordingly. This seems wrong, we should have the 'read-from-BIOS' flow (iwl_acpi_get_tas in iwlwifi) reading/parsing/validating the table from BIOS, and the 'send-to-FW' flow (iwl_mvm_tas_init) doing all the FW versioning checks and cmd filling.
