5d30f927ea wpa_supplicant: Restore permanent MAC address on reassociation
With mac_addr=0 and preassoc_mac_addr=1, the permanent MAC address
should be restored for association. Previously this did not happen when
reassociating to the same ESS.

e3e2fe3a42 Always propagate scan results to all interfaces
Scan results were not propagated to all interfaces if scan results
started a new operation, in order to prevent concurrent operations. But
this can cause other interfaces to trigger a new scan when scan results
are already available. Instead, always notify other interfaces of the
scan results, but note that new operations are not allowed.

33111c910b Check for NULL qsort() base pointers
There are a couple of places in wpa_supplicant/hostapd where qsort() can
be called with a NULL base pointer. This results in undefined behavior
according to the C standard and with some standard C libraries (ARM RVCT
2.2) results in a data abort/memory exception. Fix this by skipping such
calls since there is nothing needing to be sorted.

4b5b8a53a1 WPS: Force BSSID for WPS provisioning step connection
This was already done for most driver cases, but it is possible that the
BSSID/frequency is not forced if the driver reports BSS selection
capability (e.g., NL80211_ATTR_ROAM_SUPPORT). That could potentially
result in the driver ignoring the BSSID/frequency hint and associating
with another (incorrect) AP for the WPS provisioning step if that
another AP in the same ESS is more preferred (e.g., better signal
strength) by the driver and only one of the APs (the not preferred one)
is in active WPS registrar state.

While most drivers follow the BSSID hint for the initial connection to
an ESS, not doing it here for the WPS provisioning would break the
protocol. Fix this by enforcing a single BSSID/frequency to disallow the
driver from selecting an incorrect AP for the WPS provisioning
association.

This changes 4-way handshake authenticator processing to decrypt the
EAPOL-Key frames using an AEAD cipher (AES-SIV with FILS AKMs) before

2/4 RSN element processing to happen only after the PTK has been derived

having to maintain two code paths for this.

2022f1d08d FILS: Use AEAD cipher to protect EAPOL-Key frames (STA)
This modifies wpa_eapol_key_send() to use AEAD cipher (AES-SIV for FILS
AKMs) to provide both integrity protection for the EAPOL-Key frame and
encryption for the Key Data field. It should be noted that this starts
encrypting the Key Data field in EAPOL-Key message 2/4 while it remains
unencrypted (but integrity protected) in non-FILS cases. Similarly, the
empty Key Data field in EAPOL-Key message 4/4 gets encrypted for AEAD
cases.

6d014ffc6e Make struct wpa_eapol_key easier to use with variable length MIC
Suite B 192-bit addition from IEEE Std 802.11ac-2013 replaced the
previous fixed length Key MIC field with a variable length field. That
change was addressed with an addition of a new struct defined for the
second MIC length. This is not really scalable and with FILS coming up
with a zero-length MIC case for AEAD, a more thorough change to support
variable length MIC is needed.

Remove the Key MIC and Key Data Length fields from the struct
wpa_eapol_key and find their location based on the MIC length
information (which is determined by the AKMP). This change allows the
separate struct wpa_eapol_key_192 to be removed since struct
wpa_eapol_key will now include only the fixed length fields that are
shared with all EAPOL-Key cases in IEEE Std 802.11.

96590564d6 FT: Allow PMK-R0 and PMK-R1 for FT-PSK to be generated locally
Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.

This patch introduces the generation of the required PMKs locally for
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.

So for FT-PSK networks, no configuration of inter-AP communication is
needed anymore when using ft_psk_generate_local=1 configuration. The
default behavior (ft_psk_generate_local=0) remains to use the pull/push
protocol.

the requested value now that wpa_supplicant implementation is fixed to
