When connecting to a WPA-EAP network and the MAC address is changed
just before the association (for example by NetworkManager, which sets
a random MAC during scans), the authentication sometimes fails in the
following way ('####' logs added by me):

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

This extends dpp_test functionality to allow DPP exchanges to be stopped
after authentication is completed on the Initiator, i.e., after sending
out the Authentication Confirm message. Previously, dpp_test=89 was used

be able to stop the protocol exchange on a device that acts as
authentication Initiator and Enrollee.

Force use of the wildcard BSSID address in GAS query frames with DPP

specification mandates this and the use of GAS here is really outside

If a DPP_STOP_LISTEN call happens to be received when there is a pending

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

Previously, wpas_p2p_select_go_freq_no_pref() ended up selecting a 2.4
GHz band channel first before even considering 5 or 60 GHz channels.
This was likely done more or less by accident rather than by design when
the 5 GHz and 60 GHz band extensions were added. It seems reasonable to
enhance this by reordering the code to start with 5 and 60 GHz operating
classes and move to 2.4 GHz band only if no channel was available in 5
or 60 GHz bands for P2P GO use.
This does have some potential interop issues with 2.4 GHz only peer
devices when starting up an autonomous GO (i.e., without there being
prior knowledge of channels that the peers support). Upper layers are
expected to enforce 2.4 GHz selection if that is needed for some use
cases.

Previously, the code that writes mesh_rssi_threshold to a network block
always executes, but the code that reads it from network block and the
code that initializes it to a default value in a new network block are
inside #ifdef CONFIG_MESH. As a result when writing a config file it
will write mesh_rssi_threshold (since it has a non-default value) and
later fail to read the network block.
Fix this by moving the write code under #ifdef CONFIG_MESH as well.
Note, network blocks which already have mesh_rssi_threshold because of
the bug will still fail to read after the fix.

The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.
Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.

secy_init_macsec() can fail (if ->macsec_init fails), and
ieee802_1x_kay_init() should handle this and not let MKA run any
further, because nothing is going to work anyway.
On failure, ieee802_1x_kay_init() must deinit its kay, which will free
kay->ctx, so ieee802_1x_kay_init callers (only ieee802_1x_alloc_kay_sm)
must not do it. Before this patch there is a double-free of the ctx
argument when ieee802_1x_kay_deinit() was called.

Previously, CONFIG_WNM enabled build that supports WNM for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode WNM is required and there is no need for AP mode WNM.
Add support to differentiate between station mode WNM and AP mode
WNM in wpa_supplicant builds by adding CONFIG_WNM_AP that should be
used when AP mode WNM support is required in addition to station mode
WNM. This allows binary size to be reduced for builds that require
only the station side WNM functionality.

Scan results with parent TSF older than the scan start TSF are not added
to the beacon report since they are considered as scan results from
previous scans. However, for drivers that report the scan start TSF but
not the parent TSF of each scan result, the parent TSF will be zero so
valid scan results will be dropped.
Fix this by filtering scan results by the parent TSF only if the
driver supports reporting the parent TSF for each scan result.
