SAE: Use correct SSID profile for SAE auth retries during external auth
Previously, wpa_supplicant was using the current SSID for building the
SAE authentication commit frame for retries during external

SAE: Make sure H2E PT is derived for external auth SSID profile
The driver's SME may choose a BSS of a different ESS (SSID) compared to
the current SSID and trigger external authentication. If the chosen SSID
is not associated/selected before by wpa_supplicant it won't have the

Use the MLD MAC Address instead of link address in CCMP/GCMP AAD/nonce
construction when processing an individually addressed Data frame with
FromDS=1 or ToDS=1 between an AP MLD and non-AP MLD.
wlantest: Use link BSS entry instead of AP MLD entry for EAPOL-Key frames
SA/DA in EAPOL-Key frames might not be the BSSID when MLO is used. Check
for these cases to avoid adding unexpected BSS entries for AP MLD
instead of the per-link BSS entry. This is needed to be able to find the
derived keys when decrypting protected frames.
wlantest: Distinguish EAPOL-Key msg 4/4 from 2/4 based on Key Nonce
IEEE P802.11be adds the MAC Address KDE into the EAPOL-Key msg 4/4 when
MLO is used and as such, the previously used check for Key Data Length
value 0 is not sufficient for recognizing the EAPOL-Key msg 4/4 anymore.
Also check for an all zero Key Nonce value since that field is supposed
to be zero in EAPOL-Key msg 4/4 and it has to be a random value in
EAPOL-Key msg 2/4.
wlantest: Use MLD MAC addresses, if known, as AA/SA in PTK derivation
When MLO is used, the MLD MAC addresses of the AP MLD and non-AP MLD are
used as the Authenticator and Supplicant addresses. Update PTK
derivation to use this information to work with MLO.
wlantest: Learn MLD MAC address from EAPOL-Key msg 1/4 and 2/4
IEEE P802.11be indicates the MLD MAC addresses, i.e., the Authenticator
and Supplicant addresses, in the MAC Address KDE in EAPOL-Key msg 1/4
and 2/4. Learn those addresses so that wlantest can be extended to
support MLO.
Verify that the MAC Address KDE includes enough data to contain a MAC
address as a part of the parsing function so that each caller would not
need to verify this separately. None of the existing users of this
parser actually needed the MAC address value, so there was not any use
for the length field before. The updated design is more robust for
future uses and gets rid of that unused length field as well.
Fix expiration logic for the first PTKSA cache entry
When an entry is added to the PTKSA cache, timer expiration is not set.
Check the list and set the timer expiration when the list is empty also.
When another entry is added to the list, it is placed before the relavant
entry in the order of expiry time of all entries present in the list.
PASN: Set secure ranging context to driver after association
After the secure association and PTK derivation are completed, if the
device supports LTF keyseed, generate the LTF keyseed using KDK and set
the ranging context to the driver by using the command
QCA_NL80211_VENDOR_SUBCMD_SECURE_RANGING_CONTEXT.
PASN: Configure secure ranging context to the driver in AP mode
AP as a responder, on successful completion of PASN authentication
configures the required keys by using the command
QCA_NL80211_VENDOR_SUBCMD_SECURE_RANGING_CONTEXT to the driver.
nl80211: Define vendor interface functions to offload PASN authentication
This defines the QCA vendor interface functions to offload PASN
authentication from the driver.
The driver sends the QCA_NL80211_VENDOR_SUBCMD_PASN event requesting to
perform PASN authentication with a list of peers with which the driver
needs to do ranging. wpa_supplicant performs PASN handshake with all the
peer devices and sets the required keys using the command
QCA_NL80211_VENDOR_SUBCMD_SECURE_RANGING_CONTEXT to the driver. After
PASN handshake is completed with all requested peers, wpa_supplicant
sends consolidated status for all peers to the driver.
PASN: Set keys from PTKSA cache for a valid PTKSA entry
Set secure ranging context to the driver for a valid PTKSA entry in the
PTKSA cache, if available. When the driver requests for PASN keys,
wpa_supplicant configures the keys from its cache if the keys for the
peer derived with the same own MAC address are available in the cache
instead of doing the full PASN handshake again.
nl80211: Allow PASN Authentication frames with random (foreign) MAC address
To support secure ranging with a random MAC address, PASN handshake is
performed with a different source MAC address from the device's own
interface address. Hence, allow PASN Authentication frames with any
foreign MAC address to further process the Authentication frames.
PASN: Deauthenticate on PTKSA cache entry expiration
Add an option for an alternative processing of PTKSA life time expiry.
Register a callback in wpa_supplicant to handle the life time expiry of
the keys in PTKSA cache. Send PASN deauthentication when a PTKSA cache

PASN: Offload handshake for multiple peers from the driver
This brings in the functionality to hold multiple peers and perform PASN
authentication with each peer at a time and send the PASN response to
the driver. PASN parameters such as AKMP and cipher suite are obtained
from the BSS information of the cached scan results. Also add
functionality to trigger deauthentication to the peer for which PASN
