10749c3c48 mbssid: Process Known BSSID element
Process the Known BSSID elements if included by non-AP stations. The
format is described in IEEE Std 802.11ax-2021, 9.4.2.261.

Non-AP stations may include this element in directed Probe Request
frames to indicate which of the multiple BSSIDs they have already
discovered. AP should exclude these profiles from the Probe Response
frame.

Add Multiple BSSID Configuration element data per IEEE Std

c5a09b051a mbssid: Add Non-Inheritance element
Add data per IEEE Std 802.11-2020, 9.4.2.240. Current implementation is
added for the security and extended supported rates only.

For the Extended rates element, add a new member 'xrates_supported'
which is set to 1 only if hostapd_eid_ext_supp_rates() returns success.
Without this change, there are cases where this function returns before
adding the element for the transmitting interface resulting in incorrect
addition of this element inside the MBSSID Non-Inheritance element.

920b56322d mbssid: Functions for building Multiple BSSID elements
Add Multiple BSSID element data per IEEE Std 802.11ax-2021, 9.4.2.45.
Split the BSSes into multiple elements if the data does not fit in
the 255 bytes allowed for a single element.

Store the total count of elements created and the offset to the start
of each element in the provided buffer.

Set the DTIM periods of non-transmitted profiles equal to the EMA
profile periodicity if those are not a multiple of the latter already as
recommended in IEEE Std 802.11ax-2021, Annex AA (Multiple BSSID
configuration examples).

9a2781f243 wpa_supplicant: Support throughput estimation for EHT rates
Add support to consider EHT rates while calculating the estimated
throughput for scan results.

- The estimated EHT throughput uses the HE 0.8 usec GI rates from the
  relevant EHT-MCS tables from IEEE P802.11be/D2.0, 36.5.
- The minimum SNR values for EHT rates (4096-QAM) are derived by adding
  the existing minimum SNR values of 1024-QAM rates from HE tables and
  the difference between the values of minimum sensitivity levels of
  1024-QAM rates and 4096-QAM rates defined in Table 36-67 (Receiver
  minimum input level sensitivity) in IEEE P802.11be/D2.0.

 - store public key hash in PMKSA from DPP Network

6af717f73b DPP: Don't close TCP connection for duplicate Presence Announcements
If wpa_supplicant receives a duplicate DPP chirp over a TCP connection
this causes the connection (and all of its state) to be torn down.
Such a tear-down means that the authentication request state is discarded.
That in turn will cause any otherwise valid authentication response
to not succeed.

This commit addresses that problem. It also does not attempt to check
for duplicates until at least we know that we have an appropriate hash.

b6d3fd05e3 FT: Use SHA256 to derive PMKID for AKM 00-0F-AC:3 (FT-EAP)
PMKSA caching for the FT initial mobility domain association was fully
defined in IEEE Std 802.11-2020. The state before that was unclear and
there has been interoperability issues in this area, so use of PMKSA
caching with FT-EAP has been disabled in wpa_supplicant by default.

The wpa_supplicant and hostapd implementation of PMKSA caching for FT
ended up using an earlier default mechanism (SHA-1) for deriving the
PMKID when using the FT-EAP. This does not match what got defined in
IEEE Std 802.11-2020, 12.11.2.5.2 (SHA256). It is not really desirable
to use SHA-1 for anything with FT since the initial design of FT was
based on SHA256. Furthermore, it is obviously not good to differ in
behavior against the updated standard. As such, there is sufficient
justification to change the implementation to use SHA256 here even
though this ends up breaking backwards compatibility for PMKSA caching
with FT-EAP.

As noted above, this is still disabled in wpa_supplicant by default and
this change results in PMKSA caching not working only in cases where it
has been enabled explicitly with ft_eap_pmksa_caching=1. Those cases
recover by falling back to full EAP authentication.

40a42613e6 FT: Simplify FTE parsing for FT-SAE-EXT-KEY using MIC Length subfield
Commit 25b52e5f83 ("FT: Extend FTE parsing for FT-SAE-EXT-KEY") used
possible MIC length iteration to try to figure out the length of the MIC
field in FTE. That was the only option available at the time, but FTE is
now being extended in IEEE 802.11-REVme to explicitly indicate the
length of the MIC field for the new FT-SAE-EXT-KEY AKM to make this
easier.

Use the new design from the approved comment resolution (*) in
REVme/D2.0 ballot CID 3135 to simplify implementation. This gets rid of
the need to pass in key length and the somewhat strange need_{r0kh,r1kh}
parameters to wpa_ft_parse_ies().
