97302b39dc wlantest: Try harder to find a STA entry with PTK for 4-address frames
Commit aab6612836 ('wlantest: Search
bss/sta entry more thoroughly for 4-address frames') allowed wlantest to
find a STA entry in this type of cases, but it was still possible for
that STA entry to be the one that has no derived PTK while the STA entry
for the other side of the link might have the derived PTK available.

Extend this BSS/STA selection mechanism to use sta->ptk_set to determine
which STA entry is more useful for decryption, i.e., select the one with
a known PTK.

aab6612836 wlantest: Search bss/sta entry more thoroughly for 4-address frames
Previous design worked for the case where only one of the devices was
beaconing, but failed in one direction to find the PTK if both devices
beaconed. Fix this by checking the A1/A2 fields in both directions if
the first pick fails to find the sta entry.

In addition, select the proper rsc value (rsc_tods vs. rsc_fromds) based
on A2 (TA) value for ToDS+FromDS frames to avoid reporting incorrect
replay issues.

878723b920 wlantest: Do not ignore RSN/WPA/OSEN element before full BSS info
wlantest used to ignore RSN/WPA/OSEN element in (Re)Association Request
frame if no Beacon frame had been seen from the AP before the
association exchange. This could result in not being able to derive keys
properly. Work around this by skipping that step if the BSS entry is not
yet complete.

4158b80eef wlantest: Do not update RSC on replays
This changes wlantest behavior to mark CCMP/TKIP replays for more cases
in case a device is resetting its TSC. Previously, the RSC check got
cleared on the first marked replay and the following packets were not
marked as replays if they continued incrementing the PN even if that PN
was below the highest value received with this key at some point in the
past.

4cada9dcc1 FILS: Add DHss into FILS-Key-Data derivation when using FILS SK+PFS
This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss
here means there would not be proper PFS for the case where PMKSA
caching is used with FILS SK+PFS authentication. This was not really the
intent of the FILS design and that issue was fixed during REVmd work
with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that add DHss into FILS-Key-Data (and PTK, in practice) derivation for
the PMKSA caching case so that a unique ICK, KEK, and TK are derived
even when using the same PMK.

Note: This is not backwards compatible, i.e., this breaks PMKSA caching
with FILS SK+PFS if only STA or AP side implementation is updated.

c72df3c67c wlantest: FILS keys and (Re)Association Request/Response frames
Try to derive PTK when FILS shared key authentication is used without
PFS. The list of available PMKs is interpreted as rMSK for this purpose
and PMK and PTK is derived from that. If the resulting PTK (KEK) can be
used to decrypt the encrypted parts of (Re)Association Request/Response
frames, mark the PTK as derived so that encrypted frames during the
association can be decrypted. In addition, write a decrypted version of
the (Re)Association Request/Response frames into the output file.

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.
