A previous workaround was used to move the special operating class 130
to the end of the Supported Operating Classes element to avoid getting
any following entry being ignored or misunderstood. That is not really
the correct way of encoding the special cases, i.e., 80+80 MHz channels
that use two nonadjacent frequency segments.
Add support for encoding the 80+80 MHz channel with the 2-octet
operating class design using the Operating Class Duple sequence field of
the Supported Operating Classes element instead of listing the operating
classes that have the 80+ behavior limit set indication in Table E-4

Once the non-AP MLD is added to the driver, the driver handles the
address translation so that hostapd receives Management frames with
SA/DA being translated into MLD MAC addresses.
If the Authentication frmae is retransmitted with transaction being 1,
SA of the retransmitted Authentication frame is translated into the MLD
MAC address by the driver, and then in the function handle_auth(),
sta->mld_info.links[].peer_addr would be replaced by the MLD MAC address
even though it is supposed to be the link address.
Therefore, update the MLD information only when the STA has not yet been
added into the driver to avoid replacing the previously determined link
address with the MLD MAC address.

For some implementation, there is no link id in EAPOL event, e.g., use
drv_event_eapol_rx for receiving. Current design for such case is switch
to a link that stores the peer. However, this is error-prone because for
non-AP MLD case, sta_info is stored in all valid links but EAPOL sm is
only initialized in the association link. If EAPOL RX event is handled
in a non-association link, it will be discarded and this leads to EAPOL
timeout.

Extend RSN authenticator to be able to process EAPOL-Key msg 2/4 and 4/4
messages in cases where the Key Data field is encrypted using AES key
wrapping (i.e., non-AEAD cipher). While there is not yet any defined
case where such encryption would be used in IEEE Std 802.11-2020,
extensions are considered to be added to use such constructions (e.g.,
in IEEE P802.11bh). As such, it is good to extend the parsing and

functionality.

The initial Authenticator implementation depended on the Key Data field
being empty for EAPOL-Key msg 4/4. This worked fine for years in
practice, but in theory, vendor specific elements or KDEs could have
been added inti EAPOL-Key msg 4/4 and that would have broken this
design. In addition, the MLD case did introduce a KDE into EAPOL-Key msg
4/4 and required changes here.
As an initial step to make this more robust for future extensions,
recognize a received EAPOL-Key message as msg 4/4 if it is for RSN
(i.e., not WPAv1), has Secure=1, contains an unencrypted Key Data field,
and does not include RSNE.

There are bandwidth 320 MHz-1 and 320 MHz-2 channelization in EHT mode.
When using ACS, user might prefer one of the channelization or both, but
original ACS was unable to take such preference.
Another problem is that the original ACS returns only the ideal channel
but no 320 MHz channelization. The function acs_get_bw_center_chan()
also could not correctly return the center frequency of bandwidth 320
MHz that is decided by ACS.
For example, if ACS decide the ideal channel is channel 37 with
channelization 320 MHz-2 (center frequency 6265 MHz),
acs_get_bw_center_chan() returns 6105 MHz, which is 320 MHz-1.
Extend the support for 320 MHz so that ACS can choose the best channel
according to the user's preference. Also, after calling
acs_find_ideal_chan_mode(), the best channel and bandwidth can be
derived.
The changes are:
- bw_type ACS_BW320 is divided into ACS_BW320_1 and ACS_BW320_2
- in bandwidth 320 MHz, find the best channel and bandwidth according to
user's perference (320 MHz-1, 320 Mhz-2 or both are OK)
- before acs_find_ideal_chan_mode() returns, update bw320_offset in
iface->conf so that the best channel's channelization is recorded.
- get the best center frequency from bw320_offset

is the total element length (including the length of the Element ID and
Length fields as well). However, the value in the length field denotes
the number of octets following it and excluding itself. Hence including
the total length is wrong. This leads to incorrect count of Multiple
BSSID elements.
And while filling the data, the length is considered porperly as it
should be hence we are filling more data in a single go and all data is
filled in MBSSID count which is less than originally calculated. This
ultimately leads to incorrect length calculation during nla_put() and
setting the beacon to the driver fails while putting the Multiple BSSID

NL80211_ATTR_BSSID was introduced in kernel commit 2fa436b3a2a7
("nl80211: Use different attrs for BSSID and random MAC addr in scan
req") in 2016. Prior to that, only NL80211_ATTR_MAC could be used for
specifying the target BSSID. For backwards compatibility, add the
NL80211_ATTR_MAC attribute as well when not using a random MAC address.

With nl80211 we need to supress the kernel generated event for any
disconnect and deauthenticate. This code is a bit fragile, as it
assumes that an event will happen. Commit b898b65582 ("nl80211: Do
not ignore disconnect event in case of !drv->associated") changed this
to only disconnect when the driver knows it is associated (apparently
required for P2P), however, deauthentication may also occur without
being associated yet.
Looking at the issue, what we are really interested in is whether the
event belongs to a disconnect/deauth command that we have send
ourselves. Any event happening after the disconnect/deauth completes
should not be suppressed (or after the next connect/auth as that would
be sufficient). We therefore need to know from the event stream
whether events were generated before or after disconnect/deauth
command completion.
To do so, send a simple command on the nl_event socket. As this will
be returned back to us in the correct order with regard to the events.
We can therefore use it to safely reset our internal
ignore_next_local_{deauth,disconnect} variables.

The max transmit power of Standard Power (SP) Access Points (AP) on
6 GHz band and APs on 2.4 GHz and 5 GHz bands is limited by effective
isotropic radiated power (EIRP), while the max transmit power of Low
Power Indoor (LPI) APs on 6 GHz Band is limited by power spectral
density (PSD). Therefore the max transmit power of LPI APs grows as the
channel width increases, similar to the noise power which has constant
PSD.
Adjust the SNR of BSSes based on the transmit power config and max
channel width. EIRP limited APs usually have constant max transmit power
on different channel widths, their SNR decreases on larger channel width
because the noise power is higher, while PSD limited APs have constant
SNR over all channel widths.
