2023-06-06wifi: mac80211: fetch and store the EML capability informationEmmanuel Grumbach

2023-06-06wifi: mac80211: mlme: fix non-inheritence elementJohannes Berg
There were two bugs when creating the non-inheritence element: 1) 'at_extension' needs to be declared outside the loop, otherwise the value resets every iteration and we can never really switch properly 2) 'added' never got set to true, so we always cut off the extension element again at the end of the function This shows another issue that we might add a list but no extension list, but we need to make the extension list a zero-length one in that case. Fix all these issues. While at it, add a comment explaining the trim.

We should perhaps support this API for MLO, but it's not clear that it makes sense, in any case then we'd have to update it to probe the correct BSS.

If association to an AP without a link 0 fails, then we crash in tracing because it assumes that either ap_mld_addr or link 0 BSS is valid, since we clear sdata->vif.valid_links and then don't add the ap_mld_addr to the struct. Since we clear also sdata->vif.cfg.ap_addr, keep a local copy of it and assign it earlier, before clearing valid_links, to fix this.

2022-10-07wifi: mac80211: Parse station profile from association responseIlan Peer
When processing an association response frame for a Multi-Link connection, extract the per station profile for each additional link, and use it for parsing the link elements. As the Multi-Link element might be fragmented, add support for reassembling a fragmented element. To simplify memory management logic, extend 'struct ieee802_11_elems' to hold a scratch buffer, which is used for the defragmentation. Once an element is reconstructed in the scratch area, point the corresponding element pointer to it. Currently only defragmentation of Multi-Link element and the contained per-STA profile subelement is supported.

2022-10-07wifi: mac80211: remove/avoid misleading printsJames Prestwood
At some point a few kernel debug prints started appearing which indicated something was sending invalid IEs: "bad VHT capabilities, disabling VHT" "Invalid HE elem, Disable HE" Turns out these were being printed because the local hardware supported HE/VHT but the peer/AP did not. Bad/invalid indicates, to me at least, that the IE is in some way malformed, not missing. For the HE print (ieee80211_verify_peer_he_mcs_support) it will now silently fail if the HE capability element is missing (still prints if the element size is wrong). For the VHT print, it has been removed completely and will silently set the DISABLE_VHT flag which is consistent with how DISABLE_HT is set.

2022-09-06wifi: mac80211: isolate driver from inactive linksJohannes Berg
In order to let the driver select active links and properly make multi-link connections, as a first step isolate the driver from inactive links, and set the active links to be only the association link for client-side interfaces. For AP side nothing changes since APs always have to have all their links active. To simplify things, update the for_each_sta_active_link() API to include the appropriate vif pointer. This also implies not allocating a chanctx for an inactive link, which requires a few more changes.

It might seem a bit pointless to do a multi-link operation connection with just a single link, but this is already a big change, so for now, limit MLO connections to a single link. Extending that to multiple links will require * work on parsing the multi-link element with STA profile properly, including element fragmentation; * checking the per-link status in the multi-link element * implementing logic to have active/inactive links to let drivers decide which links should be active; * implementing multicast RX deduplication; * and likely more. For now this is still useful since it lets us do multi-link connections for the purposes of testing APIs and the higher layers such as wpa_supplicant.

2022-07-15wifi: mac80211: fix up link station creation/insertionJohannes Berg
When we create a station with a non-default link, then we should have a link address, and we definitely need to insert it into the link hash table on insertion. Split the API into with and without link creation and if it has a link, insert the link into the link hash table on sta_info_insert().

2022-07-15wifi: mac80211: limit A-MSDU subframes for client tooJohannes Berg
In AP/mesh where the stations are added by userspace, we limit the number of A-MSDU subframes according to the extended capabilities. Refactor the code and extend that also to client-side.
