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.

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.

5420bcf477 wlantest: Remove unnecessary duplication of tk_len from STA entries
The length of the TK is available within struct wpa_ptk, so there is no
need to try to maintain it separately in wlantest.

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.

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.

The TDLS link itself is bidirectional, but there is explicit

counters are stored for the current TDLS entery.

This is also changing the control interface search for TDLS counters
to require initiator/responder addresses in the correct order instead
of matching entries regardless of the role.
