6f80014b10 PASN: Allow custom PMKID in Authentication frames for Wi-Fi Aware
Wi-Fi Aware R4 specification introduces a custom PMKID derived from
Nonce and TAG. This custom PMKID is included in PASN Authentication
frames during pairing verification. So, allow use of a custom PMKID in
PASN frames and validate it using a function handler. Wi-Fi Aware
component that uses libpasn.so should take care of validating the custom
PMKID.

4022ffc5db PASN: Store AKMP in the PTKSA cache
PTK is stored in the PTKSA cache following a successful PASN handshake,
however AKMP is removed upon a WPA PASN reset. The PASN handshake is
used in the Wi-Fi Aware R4 specification to define the pairing setup
process. KDK is used to generate a new set of keys, while AKMP is
required for key derivation for pairing. So, keep AKMP in the PTKSA
cache.

Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

65a3a273cd OWE: Reuse own DH private key in AP if STA tries OWE association again
This is a workaround for mac80211 behavior of retransmitting the
Association Request frames multiple times if the link layer retries
(i.e., seq# remains same) fail. The mac80211 initiated retransmission
will use a different seq# and as such, will go through duplicate
detection. If we were to change our DH key for that attempt, there would
be two different DH shared secrets and the STA would likely select the
wrong one.

cd0813763a PASN: Include PMKID in RSNE in PASN response from AP
As defined in IEEE P802.11az/D3.0, 12.12.3.2 for the second PASN frame.
This was previously covered only for the case when the explicit PMKSA

SAE/FILS authentication cases.
