2024-02-12wifi: iwlwifi: iwlmvm: handle unprotected deauth/disassoc in d3Shaul Triebitz
In MFP, do not disconnect if an unprotected deauth or disassoc was received during D3. For that, need to configure wowlan with MFP (IS_11W_ASSOC). Now, in case of an unprotected deauth/disassoc, the wakeup reason returned by the firmware will be: IWL_WAKEUP_BY_11W_UNPROTECTED_DEAUTH_OR_DISASSOC (and not IWL_WOWLAN_WAKEUP_BY_DISCONNECTION_ON_DEAUTH which will cause a disconnection). Also, report this reason to cfg80211. In another patch, the driver will send an SA query.

2024-02-08wifi: iwlwifi: mvm: don't set replay counters to 0xffJohannes Berg
The firmware (later) actually uses the values even for keys that are invalid as far as the host is concerned, later in rekeying, and then only sets the low 48 bits since the PNs are only 48 bits over the air. It does, however, compare the full 64 bits later, obviously causing problems. Remove the memset and use kzalloc instead to avoid any old heap data leaking to the firmware. We already init all the other fields in the struct anyway. This leaves the data set to zero for any unused fields, so the firmware can look at them safely even if they're not used right now.

2024-02-08wifi: iwlwifi: mvm: fix erroneous queue index maskJohannes Berg
When retrieving the queue index ("SCD SSN") from the TX response, it's currently masked with 0xFFF. However, now that we have queues longer than 4k, that became wrong, so make the mask depend on the hardware family. This fixes an issue where if we get a single frame reclaim while in the top half of an 8k long queue, we'd reclaim-wrap the queue twice (once on this and then again on the next non-single reclaim) which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(), but could have other negative side effects (such as unmapping a frame that wasn't transmitted yet, and then taking an IOMMU fault) as well.

2024-02-08wifi: cfg80211/mac80211: move puncturing into chandefJohannes Berg
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 Grumbach
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. Wysocki
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.

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. To prevent that from happening, modify the function to populate the trip table before calling thermal_zone_device_register_with_trips().

2024-02-08wifi: iwlwifi: mvm: use correct address 3 in A-MSDUDaniel Gabay
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 Berg
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.
