eefec1e40b AES: Extend key wrap design to support longer AES keys
This adds kek_len argument to aes_wrap() and aes_unwrap() functions and
allows AES to be initialized with 192 and 256 bit KEK in addition to
the previously supported 128 bit KEK.

The test vectors in test-aes.c are extended to cover all the test
vectors from RFC 3394.

f6ff5160f0 wlantest: Add support for OSEN
This allows Hotspot 2.0 OSEN connection to be analyzed more
conveniently. The frames from an OSEN association can now be decrypted
using an MSK file.

0187c41d88 Declare wpa_debug_* variables in src/utils/wpa_debug.h
These were somewhat more hidden to avoid direct use, but there are now
numerous places where these are needed and more justification to make
the extern int declarations available from wpa_debug.h. In addition,
this avoids some warnings from sparse.

c41e1d7cac wlantest: Add more pcapng notes on EAPOL processing
Some of the MIC validation steps were not logged in the pcapng notes.
Add these to make the entries more consistent and to provide more
information to ease debugging.

a0530dff5b wlantest: Allow additional PTKs to be specified from a file
A text file with a hexdump of PTK (KCK|KEK=TK with 48 octets for CCMP or
64 octets for TKIP or alternative 16 or 32 octet TK for CCMP/TKIP) can
now be read from a file specified with the -T command line argument. If
the current known PTK fails to decrypt a frame (or if no current PTK is
known) all listed PTKs are iterated to see if any of them matches.

e4d99217f7 wlantest: Use add_note() to annotate frames
This adds debug information from wlantest into pcapng frame comments to
make the information more convenient to use, e.g., in Wireshark.

c81defea87 wlantest: Update STA info based on WPA/RSN IE in EAPOL-Key 2/4
The WPA/RSN IE in EAPOL-Key 2/4 is more reliable than the one in
(Re)Association Request frame. Update the STA info base don the
EAPOL-Key frame so that the correct cipher information is used
even if the (Re)Association Request frame is missing or corrupted
in the capture.

3c56f0e275 wlantest: Fix EAPOL-Key Key Data decryption for rekey case
KEK from TPTK needs to be used instead of from PTK when processing
rekeying case similarly to what was already done with KCK.

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.
