2024-02-08wifi: mac80211: rename ieee80211_ie_build_he_6ghz_cap()Johannes Berg
The term 'IE' isn't really in use in the spec, and I want to rework all of this to use SKBs as the primary method for building elements. Rename this one already.

2024-02-08wifi: mac80211: adjust EHT capa when lowering bandwidthJohannes Berg
If intending to associate with a lower bandwidth, remove capabilities related to 320 MHz from the EHT capabilities element. Also change the EHT MCS-NSS set accordingly: if just reducing 320->160 or similar the format doesn't change, just cut off the last bytes. If changing from higher bandwidth to 20 MHz only EHT STA, adjust the format. Note that this also requires adjusting the caller in mlme.c since the data written can now be shorter than it determined. We need to clean all that up. Since the other callers pass NULL for the conn limit, we don't need to change things there.

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: 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.

2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg
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.

2024-02-08wifi: mac80211: clean up HE 6 GHz and EHT chandef parsingJohannes Berg
In the code we currently check for support 80+80, 160 and 320 channel widths, but really the way this should be (and is otherwise) handled is that we compute the highest channel bandwidth given there, and then cut it down to what we support. This is also needed for wider bandwidth OFDMA support. Change the code to remove this limitation and always parse the highest possible channel width.

2024-02-08wifi: mac80211: clean up connection processJohannes Berg
Rewrite the station-side connection handling. The connection flags (IEEE80211_DISABLE_*) are rather confusing, and they're not always maintained well. Additionally, for wider-bandwidth OFDMA support we need to know the precise bandwidth of the AP, which is currently somewhat difficult. Rewrite this to have a 'mode' (S1G/legacy/HT/...) and a limit on the bandwidth. This is not entirely clean because some of those modes aren't completely sequenced (as this assumes in some places), e.g. VHT doesn't exist on 2.4 GHz, but HE does. However, it still simplifies things and gives us a good idea what we're operating as, so we can parse elements accordingly etc. This leaves a FIXME for puncturing, this is addressed in a later patch.

2023-10-23wifi: mac80211: purge TX queues in flush_queues flowMiri Korenblit
When this flow is invoked with the "drop" parameter as true, we only drop the frames from the hw queues, but not from the sw queues. So when we call wake_queues() after hw queue purging, all the frames from the sw queues will be TX'ed, when what we actually want to do is to purge all queues in order to not TX anything... This can cause, for example, TXing data frames to the peer after the deauth frame was sent. Fix this by purging the sw queues in addition to the hw queues if the drop parameter is true.

2023-06-14wifi: mac80211: add helpers to access sband iftype dataJohannes Berg
There's quite a bit of code accessing sband iftype data (HE, HE 6 GHz, EHT) and we always need to remember to use the ieee80211_vif_type_p2p() helper. Add new helpers to directly get it from the sband/vif rather than having to call ieee80211_vif_type_p2p(). Convert most code with the following spatch: @@ expression vif, sband; @@ -ieee80211_get_he_iftype_cap(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_he_iftype_cap_vif(sband, vif) @@ expression vif, sband; @@ -ieee80211_get_eht_iftype_cap(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_eht_iftype_cap_vif(sband, vif) @@ expression vif, sband; @@ -ieee80211_get_he_6ghz_capa(sband, ieee80211_vif_type_p2p(vif)) +ieee80211_get_he_6ghz_capa_vif(sband, vif) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Link: https://lore.kernel.org/r/20230604120651.db099f49e764.Ie892966c49e22c7b7ee1073bc684f142debfdc84@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2023-06-12wifi: mac80211: fragment per STA profile correctlyBenjamin Berg
When fragmenting the ML per STA profile, the element ID should be IEEE80211_MLE_SUBELEM_PER_STA_PROFILE rather than WLAN_EID_FRAGMENT. Change the helper function to take the to be used element ID and pass the appropriate value for each of the fragmentation levels.

There are a number of upcoming things in both the stack and drivers that would otherwise conflict, so merge wireless to wireless-next to be able to avoid those conflicts. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2023-06-06wifi: mac80211: stop warning after reconfig failuresJohannes Berg
If we have a reconfig failure in the driver, then we need to shut down the network interface(s) at the network stack level through cfg80211, which can result in a lot of those "Failed check-sdata-in-driver check, ..." warnings, since interfaces are considered to not be in the driver when the reconfiguration fails, but we still need to go through all the shutdown flow. Avoid many of these warnings by storing the fact that the stack experienced a reconfiguration failure and not doing the warning in that case.

The size of enum ieee80211_bss_change is bigger that 32, so we need u64 to be used in a flag. Also pass u64 instead of u32 to ieee80211_reconfig_ap_links() for the same reason.
