Johannes Berg 1cf1d06e95 wifi: cfg80211: allow representing NPCA in chandef
Add the necessary fields to the chandef data structure
to represent NPCA (the NPCA primary channel and NPCA
punctured/disabled subchannels bitmap), and the code
to check these for validity, compatibility, as well as
allowing it to be passed for AP mode for capable
devices.

Compatibility is assumed to only be the case when it's
actually identical, enabling later management of this
in channel contexts in mac80211 for multiple APs, but
requiring userspace to set up the identical chandef on
all AP interfaces that share a channel (and BSS color.)

Johannes Berg fb19b4d67d wifi: cfg80211: allow devices to advertise extended MLD capa/ops
For UHR, multi-link power-management capability lives there, and
so it's needed that hostapd knows what to advertise, and clients
should have it shown to userspace for information.

Repurpose the existing NL80211_ATTR_ASSOC_MLD_EXT_CAPA_OPS by
renaming it to NL80211_ATTR_EXT_MLD_CAPA_AND_OPS (with a define
for compatibility) and advertise the capabilities.

We can also later use the value, if needed, to set per-station
capabilities on STAs added to AP interfaces.

Peddolla Harshavardhan Reddy 4bb6e58bc2 wifi: cfg80211: add LTF keyseed support for secure ranging
Currently there is no way to install an LTF key seed that can be
used in non-trigger-based (NTB) and trigger-based (TB) FTM ranging
to protect NDP frames. Without this, drivers cannot enable PHY-layer
security for peer measurement sessions, leaving ranging measurements
vulnerable to eavesdropping and manipulation.

Introduce NL80211_KEY_LTF_SEED attribute and the dedicated extended
feature flag NL80211_EXT_FEATURE_SET_KEY_LTF_SEED to allow drivers
to advertise and install LTF key seeds via nl80211. The key seed
must be configured beforehand to ensure the peer measurement session
is secure. The driver must advertise both NL80211_EXT_FEATURE_SECURE_LTF
and NL80211_EXT_FEATURE_SET_KEY_LTF_SEED for the key seed installation
to be permitted.

The LTF key seed is pairwise key material and must only be used with
pairwise key type. Reject attempts to use it with other key types.

Peddolla Harshavardhan Reddy 410aa47fd9 wifi: cfg80211: allow suppressing FTM result reporting for PD requests
Proximity detection often does not require detailed ranging
measurements, yet userspace currently receives full FTM results for
every request, causing unnecessary data transfer, host wakeups, and
processing overhead.

Add an optional control to suppress ranging result reporting for
peer-to-peer PD requests. Introduce the
NL80211_PMSR_FTM_REQ_ATTR_PD_SUPPRESS_RESULTS flag; when set with a
PD request, the device may perform the measurements (e.g. when acting
as RSTA) but must not report the measurement results to userspace.

Validate that the flag is only accepted when request_type is set to
NL80211_PMSR_FTM_REQ_TYPE_PD, reject otherwise.

parameters as per the Wi-Fi Alliance specification "Proximity Ranging
(PR) Implementation Consideration Draft 1.9 Rev 1, section 5.3". Add
new FTM request attributes for min/max time between measurements,
nominal time (mandatory for NTB), AW duration, and total measurement

Add NL80211_PMSR_PEER_ATTR_REQ_TYPE attribute using the new
nl80211_peer_measurement_ftm_req_type enum to allow userspace to

Introduce Proximity Detection (PD) capabilities in Peer Measurement
Service (PMSR) as defined in the Wi-Fi Alliance specification
"Proximity Ranging (PR) Implementation Consideration Draft 1.9 Rev 1
section 3.3". This enables devices to advertise peer to peer ranging
support.

the single support_rsta flag with nested ista and rsta sub-structs,
each carrying per-mode flags for Non-Trigger Based (NTB), Trigger Based
(TB), and EDCA based ranging. This allows drivers to advertise detailed
role and protocol support for both initiator and responder roles.

Add support to pass additional ISTA and RSTA role capabilities to
userspace using new nested ISTA_CAPS and RSTA_CAPS attributes. The
legacy RSTA_SUPPORT flag is retained for backward compatibility.

Add NL80211_PMSR_FTM_CAPA_ATTR_TYPE_CAPS nested attribute using the
nl80211_peer_measurement_ftm_type_capa enum with two sub-flags:
NL80211_PMSR_FTM_TYPE_CAPA_ATTR_INFRA_SUPPORT for STA-to-AP or
AP-to-STA ranging, and NL80211_PMSR_FTM_TYPE_CAPA_ATTR_PD_SUPPORT
for peer-to-peer ranging.

Add CONCURRENT_ISTA_RSTA_SUPPORT as a FTM capability flag indicating
the device can simultaneously act as initiator and responder in a
multi-peer measurement request.

Extend FTM capabilities with antenna configuration fields
(max_no_of_tx_antennas, max_no_of_rx_antennas) for the PR Element
during PASN negotiation, and ranging interval limits
(min_allowed_ranging_interval_edca, min_allowed_ranging_interval_ntb)
to advertise device timing constraints for EDCA and NTB-based ranging.

Update the FTM request validation path in pmsr.c to check RSTA
requests against the per-mode rsta capabilities (NTB, TB, EDCA),
rejecting requests for modes the device does not support.

Add a new wdev-only interface type NL80211_IFTYPE_PD to support
Proximity Detection (PD) operations such as PASN and peer measurement
operations. This interface type operates without a netdev, similar to
P2P_DEVICE and NAN interfaces.

Implement support across cfg80211 and mac80211 layers with PD-specific
checks gated by the NL80211_EXT_FEATURE_SECURE_RTT feature flag,
management frame registration and transmission capabilities, and proper
channel context handling where PD interfaces are excluded from bandwidth
calculations. Update mac80211 to recognize the new interface type in the
relevant paths for this management-only interface.

PD discovery can be performed on any available interface, such as
NL80211_IFTYPE_STATION.

If PD/PMSR uses the MAC address of an existing interface type, such as
NL80211_IFTYPE_STATION, then pairing and measurement shall use that
same interface. If PD/PMSR uses a different MAC address, such as a
random MAC address, then pairing and measurement can be performed on a
new NL80211_IFTYPE_PD interface created with that random MAC address.

Kavita Kavita 829b815e91 wifi: cfg80211: indicate (Re)Association frame encryption to userspace
In SME-in-driver mode, the driver handles the entire (re)association
exchange. Userspace (e.g., wpa_supplicant) currently has no explicit
indication of whether the (re)association exchange was encrypted,
making it difficult to distinguish EPP (Enhanced Privacy Protection,
IEEE 802.11bi) associations from non-EPP associations.

When (Re)Association frame encryption is used, the (Re)Association
Response frame must contain a Key Delivery element as specified in
IEEE P802.11bi/D4.0, Table 9-65. Userspace must process this element
only when the (Re)Association Response frame is actually encrypted.
Processing it unconditionally for unencrypted frames leads to incorrect
behavior. Without an explicit indication from the driver, userspace
cannot determine whether encryption was used and whether the Key
Delivery element is valid.

Add a new flag attribute NL80211_ATTR_ASSOC_ENCRYPTED and a
corresponding field "assoc_encrypted" in cfg80211_connect_resp_params
to indicate that both the (Re)Association Request and Response frames
are transmitted encrypted over the air.

For mac80211-based drivers, extend cfg80211_rx_assoc_resp_data with
the assoc_encrypted field as well, which is then propagated to
cfg80211_connect_resp_params.

Pass the flag to userspace via NL80211_CMD_CONNECT event.

Miri Korenblit 1f1101c29e wifi: nl80211: add support for NAN stations
There are 2 types of logical links with a NAN peer:
- management (NMI), which is used for Tx/Rx of NAN management frames.
- data (NDI), which is used for Tx/Rx of data frames, or non-NAN
  management frames.

The NMI station has two roles:
- representation of the NAN peer - for example, the peer's schedule
  and the HT, VHT, HE capabilities - belong to the NMI station, and not to
  the NDI ones.
- Tx/Rx of NAN management frames to/from the peer.

The NDI station is used for Tx/Rx data frames of a specific NDP that was
established with the NAN peer.

Note that a peer can choose to reuse its NMI address as the NDI address.
In that case, it is expected that two stations will be added even though
they will have the same address.

- An NDI station can only be added after the corresponding NMI station
  was configured with capabilities.
- All the NDI stations will be removed before the NDI interface is brought
  down.
- All NMI stations will be removed before NAN is stopped.
- Before NMI sta removal, all corresponding NDI stations will be removed

Add support for adding, removing, and changing NMI and NDI stations.

Miri Korenblit bd11c96604 wifi: cfg80211: separately store HT, VHT and HE capabilities for NAN
In NAN, unlike in other modes, there is only one set of (HT, VHT, HE)
capabilities that is used for all channels (and bands) used in the NAN
data path.

This set of capabilities will have to be a special one, for example - have
the minimum of (HT-for-5 GHz, HT-for-2.4 GHz), careful handling of the
bits that have a different meaning for each band, etc.

While we could use the exiting sband/iftype capabilities, and require
identical capabilities for all bands (makes no sense since this means
that we will have VHT capabilities in the 2.4 GHz slot),
or require that only one of the sbands will be set,
or have logic to extract the minimum and handle the conflicting bits -
it seems simpler to add a dedicated set of capabilities which is special
for NAN, and is band agnostic, to be populated by the driver.

That way we also let the driver decide how it wants to handle the
conflicting bits.

Add this special set of these capabilities to wiphy:nan_capabilities, to be

Miri Korenblit 0e8ec738a7 wifi: cfg80211: add support for NAN data interface
This new interface type represents a NAN data interface (NDI).
It is used for data communication with NAN peers.

Note that the existing NL80211_IFTYPE_NAN interface, which is the NAN
Management Interface (NMI), is used for management communication.

An NDI interface is started when a new NAN data path is about to
be established, and is stopped after the NAN data path is terminated.

- An NDI interface can only be started if the NMI is running, and NAN is
  started.
- Before the NMI is stopped, the NDI interfaces will be stopped.

Add the new interface type, handle add/remove operations for it,
and makes sure of the conditions above.

Miri Korenblit 6e78b70c9a wifi: cfg80211: Add an API to configure local NAN schedule
Add an nl80211 API to allow user space to configure the local NAN
schedule.
The local schedule consists of a list of channel definitions and a schedule
map, in which each element covers a time slot and indicates on what
channel the device should be in that time slot.

Channels can be added to schedule even without being scheduled, for
reservation purposes.

A schedule can be configured either immedietally or be deferred, in case
there are already connected peers.
When the deferred flag is set, the command is a request from the device
to perform an announced schedule update: send the updated NAN
Availability - as set in this command - to the peers, and do the
actual switch to the new schedule on the right time (i.e. at the end of
the slot after the slot in which the update was sent to the peers).
In addition, a notification will be sent to indicate a deferred update
completion.

When the AP has an advertised TID to Link Mapping (TTLM) it shall
include the element in the association response. As such, when this
element is present it needs to be used for the currently dormant links.
See Draft P802.11REVmf_D1.0 section 35.3.7.2.3 ("Negotiation of TTLM")
for the details. The flag is also not usable in case userspace wants to
specify a negotiated TTLM during association.

Note that for the link reconfiguration case, mac80211 did not use the
information. Draft P802.11REVmf_D1.0 states in section 35.3.6.4 ("Link
reconfiguration to the setup links) that we "shall operate with all the
TIDs mapped to the newly added links ..."

All this means that the flag is not needed. The implementation should
parse the information from the association response.

Lachlan Hodges d0688dc2b1 wifi: cfg80211: correctly implement and validate S1G chandef
Currently, the S1G channelisation implementation differs from that of
VHT, which is the PHY that S1G is based on. The major difference between
the clock rate is 1/10th of VHT. However how their channelisation is
represented within cfg80211 and mac80211 vastly differ.

To rectify this, remove the use of IEEE80211_CHAN_1/2/4.. flags that were
previously used to indicate the control channel width, however it should be
implied that the control channels are 1MHz in the case of S1G. Additionally,
introduce the invert - being IEEE80211_CHAN_NO_4/8/16MHz - that imply
the control channel may not be used for a certain bandwidth. With these
new flags, we can perform regulatory and chandef validation just as we would
for VHT.

To deal with the notion that S1G PHYs may contain a 2MHz primary channel,
introduce a new variable, s1g_primary_2mhz, which indicates whether we are
operating on a 2MHz primary channel. In this case, the chandef::chan points to
the 1MHz primary channel pointed to by the primary channel location. Alongside
this, introduce some new helper routines that can extract the sibling 1MHz
channel. The sibling being the alternate 1MHz primary subchannel within the
2MHz primary channel that is not pointed to by chandef::chan.

Furthermore, due to unique restrictions imposed on S1G PHYs, introduce
a new flag, IEEE80211_CHAN_S1G_NO_PRIMARY, which states that the 1MHz channel
cannot be used as a primary channel. This is assumed to be set by vendors
as it is hardware and regdom specific, When we validate a 2MHz primary channel,
we need to ensure both 1MHz subchannels do not contain this flag. If one or
both of the 1MHz subchannels contain this flag then the 2MHz primary is not
permitted for use as a primary channel.

Properly integrate S1G channel validation such that it is implemented
according with other PHY types such as VHT. Additionally, implement a new
S1G-specific regulatory flag to allow cfg80211 to understand specific
vendor requirements for S1G PHYs.

Andrei Otcheretianski 1ccfd8db34 wifi: cfg80211: Add cluster joined notification APIs
The drivers should notify upper layers and user space when a NAN device
joins a cluster. This is needed, for example, to set the correct addr3
in SDF frames. Add API to report cluster join event.

Andrei Otcheretianski ba9b2ceaa2 wifi: nl80211: Add NAN Discovery Window (DW) notification
This notification will be used by the device to inform user space
about upcoming DW. When received, user space will be able to prepare
multicast Service Discovery Frames (SDFs) to be transmitted during the
next DW using %NL80211_CMD_FRAME command on the NAN management interface.
The device/driver will take care to transmit the frames in the correct
timing. This allows to implement a synchronized Discovery Engine (DE)
in user space, if the device doesn't support DE offload.
Note that this notification can be sent before the actual DW starts as
long as the driver/device handles the actual timing of the SDF
transmission.

Andrei Otcheretianski 01b4a3061b wifi: nl80211: Add more configuration options for NAN commands
Current NAN APIs have only basic configuration for master
preference and operating bands. Add and parse additional parameters
which provide more control over NAN synchronization. The newly added
attributes allow to publish additional NAN attributes and vendor
elements in NAN beacons, control scan and discovery beacons
periodicity, enable/disable DW notifications etc.

Arend van Spriel 4f652a390d wifi: nl80211: strict checking attributes for NL80211_CMD_SET_BSS
Assure user-space only modifies attributes for NL80211_CMD_SET_BSS
that are supported by the driver. This stricter checking is only done
when user-space commits to it by including NL80211_ATTR_BSS_PARAM.

Arend van Spriel 2418553491 wifi: nl80211: allow drivers to support subset of NL80211_CMD_SET_BSS
The so-called fullmac devices rely on firmware functionality and/or API to
change BSS parameters. Today there are limited drivers supporting the
nl80211 primitive, but they only handle a subset of the bss parameters
passed if any. The mac80211 driver does handle all parameters and stores
their configured values. Some of the BSS parameters were already conditional
by wiphy->features. For these the wiphy->bss_param_support and wiphy->features
fields are silently aligned in wiphy_register(). Maybe better to issue a warning
instead when they are misaligned.

Muna Sinada d0bf06158c wifi: nl80211: Add EHT fixed Tx rate support
Add new attributes to support EHT MCS/NSS Tx rates and EHT GI/LTF.
Parse EHT fixed MCS/NSS Tx rates and EHT GI/LTF values passed by the
userspace, validate and add as part of cfg80211_bitrate_mask.

MCS mask is constructed by new function, eht_build_mcs_mask(). Max NSS
supported for MCS rates of 7, 9, 11 and 13 is utilized to set MCS
bitmask for each NSS. MCS rates 14, and 15 if supported, are set only
for NSS = 0.

Lachlan Hodges ee63609454 wifi: mac80211: support block bitmap S1G TIM encoding
An S1G TIM PVB is encoded differently compared to a non-s1g TIM PVB.
As the AP dictates which encoding mode it uses, here we only implement
block bitmap encoding. This is the default encoding mode used by
all current vendor implementations.

Additionally, S1G has a maximum AID count of 8192, however we are
limiting the current implementation to 1600. This has no resemblence
to the standard and is purely an implementation detail. The reason for
this is due to the TIM elements maximum length of 255. This allows for,
at most, 25 encoded blocks for a PVB encoded with block bitmap. Support
for the maximum of 8192 AIDs will require an implementation of page slicing
to be added to mac80211.

As a result, we perform extra validation on both the STA and AP side
when receiving an AID as an S1G interface.

Add support for block bitmap encoding for an S1G AP and limit the
maximum AID count to 1600 for the current mac80211 implementations.

Lachlan Hodges 6624a0af82 wifi: cfg80211: support configuring an S1G short beaconing BSS
S1G short beacons are an optional frame type used in an S1G BSS
that contain a limited set of elements. While they are optional,
they are a fundamental part of S1G that enables significant
power saving.

Expose 2 additional netlink attributes,
NL80211_ATTR_S1G_LONG_BEACON_PERIOD which denotes the number of beacon
intervals between each long beacon and NL80211_ATTR_S1G_SHORT_BEACON
which is a nested attribute containing the short beacon tail and
head. We split them as the long beacon period cannot be updated,
and is only used when initialisng the interface, whereas the short
beacon data can be used to both initialise and update the templates.
This follows how things such as the beacon interval and DTIM period
currently operate.

During the initialisation path, we ensure we have the long beacon
period if the short beacon data is being passed down, whereas
the update path will simply update the template if its sent down.

The short beacon data is validated using the same routines for regular
beacons as they support correctly parsing the short beacon format
while ensuring the frame is well-formed.
