wifi: cfg80211: reject HTC bit for management frames

2025-08-28T14:25:55+00:00

[ Upstream commit be06a8c7313943109fa870715356503c4c709cbc ] Management frames sent by userspace should never have the order/HTC bit set, reject that. It could also cause some confusion with the length of the buffer and the header so the validation might end up wrong.

wifi: cfg80211: reject auth/assoc to AP with our address

2023-09-23T09:11:03+00:00

[ Upstream commit 5d4e04bf3a0f098bd9033de3a5291810fa14c7a6 ] If the AP uses our own address as its MLD address or BSSID, then clearly something's wrong. Reject such connections so we don't try and fail later. Reported-by: syzbot+2676771ed06a6df166ad@syzkaller.appspotmail.com Signed-off-by: Johannes Berg Signed-off-by: Sasha Levin

wifi: cfg80211/nl80211: move rx management data into a struct

2022-07-22T12:28:26+00:00

The functions for reporting rx management take many arguments. Collect all the arguments into a struct, which also make it easier to add more arguments if needed. Signed-off-by: Avraham Stern Signed-off-by: Johannes Berg

wifi: mac80211: remove stray printk

2022-07-15T13:05:35+00:00

Unfortunately, a printk snuck into a previous patch, remove it. Fixes: 81151ce462e5 ("wifi: mac80211: support MLO authentication/association with one link") Signed-off-by: Johannes Berg

wifi: mac80211: support MLO authentication/association with one link

2022-07-15T09:43:24+00:00

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. Signed-off-by: Johannes Berg

wifi: cfg80211: extend cfg80211_rx_assoc_resp() for MLO

2022-07-15T09:43:17+00:00

Extend the cfg80211_rx_assoc_resp() to cover multiple BSSes, the AP MLD address and local link addresses for MLO. Signed-off-by: Johannes Berg

wifi: cfg80211: put cfg80211_rx_assoc_resp() arguments into a struct

2022-07-15T09:43:17+00:00

For MLO we'll need a lot more arguments, including all the BSS pointers and link addresses, so move the data to a struct to be able to extend it more easily later. Signed-off-by: Johannes Berg

wifi: cfg80211: prepare association failure APIs for MLO

2022-07-15T09:43:16+00:00

For MLO, we need the ability to report back multiple BSS structures to release, as well as the AP MLD address (if attempting to make an MLO connection). Unify cfg80211_assoc_timeout() and cfg80211_abandon_assoc() into a new cfg80211_assoc_failure() that gets a structure parameter with the necessary data. Signed-off-by: Johannes Berg

wifi: cfg80211: remove BSS pointer from cfg80211_disassoc_request

2022-07-15T09:43:16+00:00

The race described by the comment in mac80211 hasn't existed since the locking rework to use the same lock and for MLO we need to pass the AP MLD address, so just pass the BSSID or AP MLD address instead of the BSS struct pointer, and adjust all the code accordingly. Signed-off-by: Johannes Berg

wifi: cfg80211: Allow MLO TX with link source address

2022-07-15T09:43:12+00:00

Management frames are transmitted from link address and not device address. Allow that. Signed-off-by: Andrei Otcheretianski Signed-off-by: Johannes Berg
