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.

2531517600 wlantest: Add -F option for assuming FCS is included
When using DLT_IEEE802_11 datalink type in a pcap file, wlantest can now
be instructed to assume there is an FCS included in the frame by adding
the new -F command line argument. This will make wlantest validate the
FCS and strip it from the frame before processing.

d0b251d2e8 wlantest: Fix handling of PTK rekeying
Use a temporary PTK buffer during 4-way handshake when rekeying PTK
so that the new EAPOL-Key frame MIC values are checked against the
new PTK and frames are decrypted using the old PTK. Take the new
PTK into use once msg 4/4 is processed and clear RSC counters at
that point (including moving of RSC update to avoid setting RSC
based on the msg 4/4).

In addition, add a workaround to handle supplicant implementations that
set Secure bit to one during PTK rekeying 4-way handshake in msg 2/4.
This was previously assumed to be msg 4/4, but the key data contents
can be used to figure out whether this is msg 2/4 even if the Secure
bit is set to one.

but the AP does not have association state). In such a case, the AP
would be sending out unprotected Deauthentication or Disassociation

this.
