This modifies struct wpa_ptk to allow the length of KCK and KEK to be
stored. This is needed to allow longer keys to be used, e.g., with
Suite B 192-bit level.

This adds support for AKM 00-0F-AC:11 to specify the integrity and
key-wrap algorithms for EAPOL-Key frames using the new design where
descriptor version is set to 0 and algorithms are determined based on
AKM.

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.

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.

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.

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.

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.

This adds debug information from wlantest into pcapng frame comments to
make the information more convenient to use, e.g., in Wireshark.

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.

KEK from TPTK needs to be used instead of from PTK when processing
rekeying case similarly to what was already done with KCK.

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.
