7cd17a4b5e wlantest: Handle FT over-the-DS association state update cleanly
It is expected for the STA entry on the target AP to move directly from
State 1 to State 3 when performing FT over-the-DS (i.e., FT Action
Request/Response frame exchange through the old AP followed by
Reassociation Request/Response frame exchange with the target AP).

a8d2ca9e23 wlantest: Do not report PMF failure without BSS supporting PMF
Previously, missing CCMP protection on Robust Management frames was
reported based on the STA having indicated MFPC=1. That is not accurate
since the AP/BSS may have MFPC=0. Report this failure only if both the
AP and STA have indicated MFPC=1, i.e., when PMF has been negotiated for
the association.

a8a277c169 wlantest: Get STA IEs based on EAPOL-Key msg 2/4 before PTK derivation
The previous implementation tried to update STA IE information based on
EAPOL-Key msg 2/4 to be able to handle captures that do not include the
(Re)Association Request frame. This was not sufficient (OSEN was not
included) and was done too late (the parsed information is needed for
PMK-to-PTK derivation).

Move the IE update step to happen before trying to derive the PTK if no
(Re)Association Request frame has been seen.

b3c43c3c24 wlantest: Allow duplicate frame processing after decryption failure
If a sniffer capture does not include FCS for each frame, but may
included frames with invalid FCS, it would be possible for wlantest to
try to decrypt the first received frame and fail (e.g., due to CCMP MIC
mismatch) because that particular frame was corrupted and then ignore
the following retry of that frame as a duplicate even if that retry has
different payload (e.g., if its reception did not show corruption).

Work around this by skipping duplicate frame detection immediately
following a decryption failure.

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.

62f05ce9c5 wlantest: Add STA counters for disconnect reason 6/7 RX
These can be useful in tests involving association state mismatch
between the AP and the STA (i.e., STA assumes it is still associated
but the AP does not have association state). In such a case, the AP
would be sending out unprotected Deauthentication or Disassociation
frames with reason code 6 or 7 depending on what frame is triggering
this.
