2023-12-12wifi: ieee80211: don't require protected vendor action framesJohannes Berg1-1/+2
For vendor action frames, whether a protected one should be used or not is clearly up to the individual vendor and frame, so even though a protected dual is defined, it may not get used. Thus, don't require protection for vendor action frames when they're used in a connection. Since we obviously don't process frames unknown to the kernel in the kernel, it may makes sense to invert this list to have all the ones the kernel processes and knows to be requiring protection, but that'd be a different change.

2023-09-25wifi: mac80211: support antenna control in injectionJohannes Berg1-0/+2
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.

2023-09-11wifi: mac80211: Use flexible array in struct ieee80211_tim_ieJeff Johnson1-3/+10
Currently struct ieee80211_tim_ie defines: u8 virtual_map[1]; Per the guidance in [1] change this to be a flexible array. Per the discussion in [2] wrap the virtual_map in a union with a u8 item in order to preserve the existing expectation that the virtual_map must contain at least one octet (at least when used in a non-S1G PPDU). This means that no driver changes are required.

In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.
