If all available channel resources are used for NAN channels, and one of
them is shared with another interface, and that interface needs to move
to a different channel (for example STA interface that needs to do a
channel or a link switch), then the driver can evacuate one of the NAN
channels (i.e. detach it from its channel resource and announce to the
peers that this channel is ULWed). In that case, the driver needs to
notify user space about the channel evacuation, so the user space can
adjust the local schedule accordingly.
Add a notification to let userspace know about it.

Add a new notification command that allows drivers to notify user space
when the device's ULW (Unaligned Schedule) blob has been updated. This
enables user space to attach the updated ULW blob to frames sent to NAN

Currently we have this ability for AP and GO. But it is now needed also for
NAN_DATA mode - as per Wi-Fi Aware (TM) 4.0 specification 6.2.5:
"If a NAN Device receives a unicast NAN Data frame destined for it, but
with A1 address and A2 address that are not assigned to the NDP, it shall
discard the frame, and should send a Data Path Termination NAF to the
frame transmitter"
To allow this, change NL80211_CMD_UNEXPECTED_FRAME to support also
NAN_DATA, so drivers can report such cases and the user space can act
accordingly.

Add an NL80211 command to configure the NAN schedule of a NAN peer.
Such a schedule contains a list of NAN channels, and a mapping from each
time slots to the corresponding channel (or unscheduled).
Also contains more information about the schedule, such as sequence ID
and map ID.
Not all of the restrictions are validated in this patch. In particular,
comparison of two maps of the same peer requires storing/retrieving each
map of each peer, only for validation.
Therefore, it is the responsibilty of the driver to check that.

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.

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
populated by the driver.
Send it to user space.

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.

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.

expected to process it and take further action - vacate the channel, or
reduce the bandwidth.

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

After NAN was started, cluster id updates from the user space should not
happen, since the device already started a cluster with the

Since NL80211_CMD_CHANGE_NAN_CONFIG requires to set the full NAN
configuration, we can't require that NL80211_NAN_CONF_CLUSTER_ID won't
be included in this command, and keeping the last confgiured value just

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.

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.

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.

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.

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.

Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.
To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM
By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

driver
In the case of SME-in-driver, the driver can internally choose to
update the links based on the AP MLD recommendation and do link
reconfiguration negotiation with AP MLD.
(e.g., After the driver processing the BSS Transition Management request
frame received from the AP MLD with Neighbor Report containing
Multi-Link element with recommended links information chooses to do link
reconfiguration negotiation with AP MLD).
To support this, extend cfg80211_mlo_reconf_add_done() and
NL80211_CMD_ASSOC_MLO_RECONF to indicate added links information for
driver-initiated link reconfiguration requests. For removed links,
the driver indicates links information using the
NL80211_CMD_LINKS_REMOVED event for driver-initiated cases, the same as
supplicant initiated cases.
For the driver-initiated case, cfg80211 will receive link
reconfiguration result asynchronously from driver so holding BSSes of
the accepted add links is needed in the event path. Also, no need of
unhold call for the rejected add link BSSes since there was no hold call
happened previously.
Once the supplicant receives the NL80211_CMD_ASSOC_MLO_RECONF event,
it needs to process the information about newly added links and install
per-link group keys (e.g., GTK/IGTK/BIGTK etc.).
In case of the SME-in-driver, using a vendor interface etc. to notify
the supplicant to initiate a link reconfiguration request and then
supplicant sending command to the cfg80211 can lead to race conditions.
The correct design to avoid this is that the driver indicates the
cfg80211 directly with the results of the link reconfiguration
negotiation.

This allows users to prevent a vif from affecting radios other than the
configured ones. This can be useful in cases where e.g. an AP is running
on one radio, and triggering a scan on another radio should not disturb it.
Changing the allowed radios list for a vif is supported, but only while
it is down.
While it is possible to achieve the same by always explicitly specifying
a frequency list for scan requests and ensuring that the wrong channel/band
is never accidentally set on an unrelated interface, this change makes
multi-radio wiphy setups a lot easier to deal with for CLI users.
By itself, this patch only enforces the radio mask for scanning requests
and remain-on-channel. Follow-up changes build on this to limit configured
frequencies.
