wifi: ieee80211: correct FILS status codes

2025-12-18T13:03:17+00:00

[ Upstream commit 24d4da5c2565313c2ad3c43449937a9351a64407 ] The FILS status codes are set to 108/109, but the IEEE 802.11-2020 spec defines them as 112/113. Update the enum so it matches the specification and keeps the kernel consistent with standard values.

wifi: mac80211: correctly initialise S1G chandef for STA

2025-09-19T09:56:07+00:00

When moving to the APs channel, ensure we correctly initialise the chandef and perform the required validation. Additionally, if the AP is beaconing on a 2MHz primary, calculate the 2MHz primary center frequency by extracting the sibling 1MHz primary and averaging the frequencies to find the 2MHz primary center frequency.

wifi: mac80211: support parsing S1G TIM PVB

2025-09-04T09:19:01+00:00

An S1G TIM PVB has 3 mandatory encoding modes, that being block bitmap, single AID and OBL alongside the ability for each encoding mode to be inverted. Introduce the ability to parse the 3 encoding formats. The implementation specification for the encoding formats can be found in IEEE80211-2024 9.4.2.5.

wifi: cfg80211/mac80211: implement dot11ExtendedRegInfoSupport

2025-07-09T09:56:37+00:00

Implement dot11ExtendedRegInfoSupport to advertise non-AP station regulatory power capability as part of regulatory connectivity element in (Re)Association request frames so that AP can achieve maximum client connectivity. Control field which was interpreted using value of 3-bits B5 to B3, now uses value of 4-bits B6 to B3 to interpret the type of AP. Hence update IEEE80211_HE_6GHZ_OPER_CTRL_REG_INFO to parse 4-bits control field. If older AP still updates only 3-bits value of control field, station can still interpret the value as per section E.2.7 of IEEE 802.11 REVme D7.0 and support the appropriate AP type. Also update IEEE80211_6GHZ_CTRL_REG_INDOOR_SP_AP as the value of standard power AP is changed to 8 instead of 4 so that AP can support both LPI AP and SP AP to maximize the connectivity with stations. For backward compatibility, keeping value 4 as old AP by limiting it to SP AP only.

wifi: cfg80211: only verify part of Extended MLD Capabilities

2025-07-09T09:52:35+00:00

We verify that the Extended MLD Capabilities are matching between links. However, some bits are reserved and in particular the Recommended Max Links subfield may not necessarily match. So only verify the known subfields that can reliably be expected to be the same. More information can be found in Table 9-417o, in IEEE P802.11be/D7.0.

wifi: mac80211: correctly identify S1G short beacon

2025-07-07T08:42:15+00:00

mac80211 identifies a short beacon by the presence of the next TBTT field, however the standard actually doesn't explicitly state that the next TBTT can't be in a long beacon or even that it is required in a short beacon - and as a result this validation does not work for all vendor implementations. The standard explicitly states that an S1G long beacon shall contain the S1G beacon compatibility element as the first element in a beacon transmitted at a TBTT that is not a TSBTT (Target Short Beacon Transmission Time) as per IEEE80211-2024 11.1.3.10.1. This is validated by 9.3.4.3 Table 9-76 which states that the S1G beacon compatibility element is only allowed in the full set and is not allowed in the minimum set of elements permitted for use within short beacons. Correctly identify short beacons by the lack of an S1G beacon compatibility element as the first element in an S1G beacon frame.

wifi: ieee80211: add Radio Measurement action fields

2025-06-20T08:43:41+00:00

Drivers that support Tx power insertion could examine the outgoing Radio measurement packet and depending on the packet type, the driver can insert specific data fields in it. These action field values will help drivers classify the action code within the Radio Measurement action packet. These action fields are defined in IEEE 802.11-2024 - Table 9-470, Radio Measurement Action field values.

All of these are really meant to be variable-length, and in the case of s1g_beacon it's actually accessed. Make that one in particular, and a couple of others (that aren't used as arrays now), actually variable.
