Wi-Fi Aware uses PASN handshake to authenticate peer devices. Devices
can simply verify each other for subsequent sessions as long as the keys
remain valid after authentication has been successful and pairing has
been established.
In pairing verification, Wi-Fi Aware devices uses PASN Authentication
frames with custom PMKID and Wi-Fi Aware R4 specific verification IEs.
It does not use wrapped data in the Authentication frames. This function
provides support to construct PASN Authentication frames for pairing
verification.

PASN responder validates auth 1 frame and sends auth 2 frame to the
initiator. It analyses the auth 3 frame and verifies successful
authentication. Wi-Fi Aware modules can reuse this functionality through
a shared library libpasn.so generated from this code. Move the PASN
functionality that is now decoupled from the hapd context into a
separate file in a common directory to make it easier to build such a

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

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

This is a step towards decoupling the PASN initiator and responder
implemenentation is decoupled from the wpa_s and hapd contexts and
moving to a common folder for better abstraction. Move the struct

The initial wpa_drv_get_mlo_info() implementation cleared only the
valid_links information within struct driver_sta_mlo_info before trying
to fetch the information from the driver. While this is likely going to
work fine in practice, this can result in static analyzer warnings on
use of uninitialized memory (e.g., mlo.assoc_link_id could have been
read if wpa_s->valid_links was set to a nonzero value). In any case, it
is better to avoid such unnecessary warnings by clearing the full data
structure before using it.
