On 6 GHz, stations don't have ht_supported set, but they can still do aggregation since they must have HE, allow that. Link: https://lore.kernel.org/r/20200528213443.776d3c891b64.Ifa099d450617b50c691832b3c4aa08959fab520a@changeidSigned-off-by:

On 6 GHz band, HE capabilities must be available for all of the interface types, otherwise we shouldn't use 6 GHz. Check this. Link: https://lore.kernel.org/r/20200528213443.5881cb3c8c4a.I583b54172f91f98d44af64a16c5826fe458cbb27@changeidSigned-off-by:

On the 6 GHz band, HE should be used, but without any direct HT/VHT capabilities, instead the HE 6 GHz band capabilities will capture the relevant information. Reject HT/VHT capabilities here.

If a 6 GHz channel exists, then we can probably safely assume that the device actually supports it, and then it should support most bandwidths. This will probably need to be extended to check the interface type and then dig into the HE capabilities for that though, to have the correct bandwidth check.

An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec). So the *3rd* bit of the 10th byte should be checked. Also, in one place, the wrong byte was checked. (cfg80211_find_ie returns a pointer to the beginning of the IE, so the data really starts at ie[2], so the 10th byte should be ie[12]. To avoid this confusion, use cfg80211_find_elem instead). Signed-off-by:

Support connecting to HE 6 GHz APs and mesh networks on 6 GHz, where the HT/VHT information is missing but instead the HE 6 GHz band capability is present, and the 6 GHz Operation information field is used to encode the channel configuration instead of the HT/VHT operation elements. Also add some other bits needed to connect to 6 GHz networks. Link: https://lore.kernel.org/r/1589399105-25472-10-git-send-email-rmanohar@codeaurora.orgCo-developed-by:

If the AP advertises inconsistent data, namely it has CCFS1 or CCFS2, but doesn't advertise support for 160/80+80 bandwidth or "Extended NSS BW Support", then we cannot use any MCSes in the the higher bandwidth. Thus, avoid connecting with higher bandwidth since it's less efficient that way.

These capabilities cover what would otherwise be transported in HT/VHT capabilities, but only a subset thereof that is actually needed on 6 GHz with HE already present. Expose the capabilities to userspace, drivers are expected to set them as using the 6 GHz band (currently) requires HE capability.

The 6GHz band does not have regulatory approval yet, but things are moving forward. However, that has led to a change in the channelization of the 6GHz band which has been accepted in the 11ax specification. It also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it. This change is primarily thrown in to discuss how to deal with it. I noticed ath11k adding 6G support with old channelization and ditto for iw. It probably involves changes in hostapd as well.

The updates to change to kHz frequencies and the 6 GHz additions evidently overlapped (or rather, I didn't see it when applying the latter), so the 6 GHz is broken. Fix this.

If we receive management frames with an HT-Control field, we cannot parse them properly, as we assume a fixed length management header. Since we don't even need the HTC field (for these frames, or really at all), just remove it at the beginning of RX. Reported-by:

Back with commit c8c240e2 (cfg80211: reg: remove support for built-in regdb, 2015-10-15), support for using CFG80211_INTERNAL_REGDB was removed in favor of loading the regulatory database as firmware file. The documentation of CFG80211_CRDA_SUPPORT was not adjusted, though, which is why it still mentions mentions the old way of loading via the internal regulatory database. Remove it so that the kernel option only mentions using the firmware file. Signed-off-by:

As discussed with Mathy almost two years ago in http://lore.kernel.org/r/20180806224857.14853-1-Mathy.Vanhoef@cs.kuleuven.be we should let userspace process SA-QUERY frames if it wants to, so that it can handle OCV (operating channel validation) which mac80211 doesn't know how to. Evidently I had been expecting Mathy to (re)send such a patch, but he never did, perhaps expecting me to do it after our discussion. In any case, this came up now with OCV getting more attention, so move the code around as discussed there to let userspace handle it, and do it properly. Signed-off-by:

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

If the driver advertises NL80211_EXT_FEATURE_SCAN_FREQ_KHZ userspace can omit NL80211_ATTR_SCAN_FREQUENCIES in favor of an NL80211_ATTR_SCAN_FREQ_KHZ. To get scan results in KHz userspace must also set the NL80211_SCAN_FLAG_FREQ_KHZ. This lets nl80211 remain compatible with older userspaces while not requring and sending redundant (and potentially incorrect) scan frequency sets. Signed-off-by:

cfg80211 recently gained the ability to understand a frequency offset component in KHz. Expose this in nl80211 through the new attributes NL80211_ATTR_WIPHY_FREQ_OFFSET, NL80211_FREQUENCY_ATTR_OFFSET, NL80211_ATTR_CENTER_FREQ1_OFFSET, and NL80211_BSS_FREQUENCY_OFFSET. These add support to send and receive a KHz offset component with the following NL80211 commands: - NL80211_CMD_FRAME - NL80211_CMD_GET_SCAN - NL80211_CMD_AUTHENTICATE - NL80211_CMD_ASSOCIATE - NL80211_CMD_CONNECT Along with any other command which takes a chandef, ie: - NL80211_CMD_SET_CHANNEL - NL80211_CMD_SET_WIPHY - NL80211_CMD_START_AP - NL80211_CMD_RADAR_DETECT - NL80211_CMD_NOTIFY_RADAR - NL80211_CMD_CHANNEL_SWITCH - NL80211_JOIN_IBSS - NL80211_CMD_REMAIN_ON_CHANNEL - NL80211_CMD_JOIN_OCB - NL80211_CMD_JOIN_MESH - NL80211_CMD_TDLS_CHANNEL_SWITCH If the driver advertises a band containing channels with frequency offset, it must also verify support for frequency offset channels in its cfg80211 ops, or return an error.

Drivers may wish to report the RX frequency in units of KHz. Provide cfg80211_rx_mgmt_khz() and wrap it with cfg80211_rx_mgmt() so exisiting drivers which can't report KHz anyway don't need to change. Add a similar wrapper for cfg80211_report_obss_beacon() so the frequency units stay somewhat consistent. This doesn't actually change the nl80211 API yet. Signed-off-by:

Current rule for applying TID configuration for specific peer looks overly complicated. No need to reject new TID configuration when override flag is specified. Another call with the same TID configuration, but without override flag, allows to apply new configuration anyway. Use the same approach as for the 'all peers' case: if override flag is specified, then reset existing TID configuration and immediately apply a new one. Signed-off-by:
