Injecting protected broadcast frames fails because of the unnecessary
null check for sta. In case of broadcast frames sta can be null, so
remove the check.

TK was incorrectly truncated in a way that resulted in CCMP (128-bit
key) encryption being used in practice.

When using DLT_IEEE802_11 datalink type in a pcap file, wlantest will now
add a radiotap header to the re-written pcap file to make sure all frames
in the output file will include the radiotap header.

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.

This is needed to allow capture files from the mac80211 cooked monitor
mode interface to be processed properly. Without this, the locally
generated frames may not get processed.

This is a generic AES CCM implementation that can be used for other
purposes than just implementing CCMP, so it fits better in a separate
file in src/crypto.

This adds 192-bit and 256-bit key support to the internal AES
implementation and extends the AES-GCM functions to accept key length to
enable longer AES key use.

There is no need to allocate a temporary buffer and build GHASH input
data into it. Instead, ghash() is trivial to split into update part that
can be called separately for each segment.

GCMP encodes length of AAD differently, so remove the unnecessary
code that got copied from the CCMP implementation.

This version can generate CCMP and TKIP test vectors that match with
the IEEE Std 802.11-2012, Annex M.6.3 and M.6.4.

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.

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

A text file with MSK/PMK entries (one key per line in hexdump format)
can be read into wlantest (-f<path to file>) to initialize list of
known PMKs.

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.

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.
The Timeout Interval element needs to use Association Comeback time
for the case when (Re)Association Response frame uses Status Code 30.
Verify this before incrementing the (re)assocresp_comeback counters.
Need to be able to handle TDLS Setup Response frame with LinkId IE
when non-zero status code is used. In addition, allow finding of a
TDLS entry based on real BSSID instead of the one used in the LinkId
to allow negative testing of different BSS.
The TDLS link itself is bidirectional, but there is explicit
initiator/responder roles. Remove the other direction of the link if it
exists when processing TDLS Setup Confirm to make sure that the link
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.
The use of the pcap subdirectory seems to be limited to some of the
newer Linux distros only, so use the older paths to pcap.h and
pcap-bpf.h to make wlantest bit more easier to compile on older
systems.
This can be used by external programs (e.g., wlantest_cli) to inject
raw frames (hex dump of the frame header and body). The data can be
requested to be sent as-is or protected with the current key.
This adds new commands for wlantest_cli to request wlantest to
inject frames. This version can only send out Authentication
frames and unprotected SA Query Request frames, but there is
now place to add more frames and encryption with future commits.
Verify that WPA/RSN IE in (Re)Association Request is identical to the
one used in EAPOL-Key message 2/4.
Verify that WPA/RSN IE in Beacon/Probe Response is identical to the
one(s) used in EAPOL-Key message 3/4.
The output file includes all the capture (or read from wireless PCAP
file) frames in their original contents and another copy of each
frame that is decrypted in wlantest (including EAPOL-Key Key Data
field).
Decrypt MPPE keys and derive PMK from RADIUS exchange if RADIUS
shared secret is known. Use the derived PMK when trying to derive
PTK during 4-Way Handshake.
Another interface (-I) or pcap file (-R) can now be specified as a
source of RADIUS packets. These packets are now parsed, but the
MSK is not yet derived for PMK use.
Allow pre-configuration of passphrases (-p<passphrase>) to provide
enough information for wlantest to be able to derive PMK for each
BSS and PTK for each STA going through 4-Way Handshake (at least
message 2 and 3 needs to be received).
This tool can be used to capture IEEE 802.11 frames either from a
monitor interface for realtime capturing or from pcap files for
offline analysis. This version is only adding basic infrastructure for
going through the frames and parsing their headers.
