bcbe80a66a AP: MLO: Handle Multi-Link element during authentication
In case the AP is an AP MLD, parse the Multi-Link element from the
Authentication frame, store the relevant information, and prepare the
response Multi-Link element.

If the AP is not an AP MLD or the parsing of the element fails, continue
the authentication flow without MLD support.

For SAE, it is needed to skip various fixed fields in
the Authentication frame. Implement it for SAE with H2E.

TODO: This should be extended to other authentication algorithms which
are allowed for MLD connections and have fixed fields in the
Authentication frames, according to IEEE P802.11-REVme/D3.0, Table 9-69
(Presence of fields and elements in Authentications frames).

This commit doesn't support FILS, FT, etc.

4120f9d7ab PASN: Introduce configuration option to allow/deny PASN-UNAUTH
Per IEEE P802.11az/D7.0, 12.12.3.2 (PASN Frame Construction and
Processing), responder should REFUSE PASN authentication frame 1 with
Base AKM as PASN AKM if dot11NoAuthPASNActivated is false. That
configuration was not previously available and hostapd was hardcoded
with dot11NoAuthPASNActivated being true.

Allow this to be configured and reject PASN authentication frame 1 from
initiator if pasn_noauth=0 and Base AKM in RSNE of this frame is PASN.
The default value for pasn_noauth is 1 to maintain previous
functionality even though the dot11NoAuthPASNActivated is defined to
have default value of false.

5d06acefdd RNR: Add elements by default for EMA AP
As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of
a nontransmitted BSSID profile, an EMA AP that transmits a Beacon
frame carrying a partial list of nontransmitted BSSID profiles
should include in the frame a Reduced Neighbor Report element
carrying information for at least the nontransmitted BSSIDs that
are not present in the Multiple BSSID element carried in that frame.

Add this support by splitting the reduced neighbor report (RNR) in as
many elements as the number of multiple BSSID elements. Each RNR element
excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will
have the data common for all EMA beacons such as neighbor AP information
gathered through neighbor reports.

The hwsim test case he_ap_ema demonstrates this support.

694a1c6873 SAE: Make sme_sae_auth() return IE offset
Authentication frames include several fixed body parts (see Table 9-68
(Authentication frame body) and Table 9-69 (Presence of fields and
elements in Authentication frames) in IEEE P802.11-REVme/D2.0).

To be able to parse the IE part, these fields need to be skipped. Since
SAE logic already implements this parsing, change SAE authentication
handling functions to return the offset to the IE part. This preparation
is needed for future MLD patches that need to parse out the ML related
elements in the Authentication frames.

c823197bde SAE: Use Challenge Failure status code in confirm message failure cases
IEEE Std 802.11-2020, 12.4.7.6 says that status code CHALLENGE_FAILURE,
needs to be sent in case the verification action fails for SAE Confirm
message frame from a STA: "An SAE Confirm message, with a status code
not equal to SUCCESS, shall indicate that a peer rejects a previously
sent SAE Confirm message. An SAE Confirm message that was not
successfully verified is indicated with a status code of
CHALLENGE_FAILURE."

hostapd, however, did not use this status code for this case. In
ieee802_11.c the function sae_check_confirm() is called and in case of
verification failure (-1 is returned), the response is set to
WLAN_STATUS_UNSPECIFIED_FAILURE (status code = 1). Fix this to use
CHALLENGE_FAILURE.
