cc046a1ff8 wlantest: Extend protected Data frame checks for GCMP and CCMP-256
The same rules that apply to CCMP-128 apply also for GCMP-128, CCMP-256,
and GCMP-256 here.

The definitions of max_args, get_cmd_arg_num(), and tokenize_cmd() are
already shared by the hostapd_cli and wpa_cli commands by including the
cli.h header. So follow the same for wlantest_cli and remove the

30cf0d107f wlantest: Properly free allocated memory on error exit paths
In the cases when a failure is experienced, the value "-1" was returned
from the main() function without doing any cleanup or deinit.

For example, if wlantest was started with the following set of command
line arguments then later when returning after a failure from main()
function, the memory allocated as part of handling the "-p" getopt
command line option was not freed. To fix memory leaks in this case,
properly free the previously allocated memory with the help of
wlantest_deinit() before returning from main().

$ sudo valgrind --leak-check=full --show-leak-kinds=all --verbose \
> --track-origins=yes --log-file=valgrind-out.txt \
> ./wlantest -i hwsim0 -dd -c -p "asdfasdfasdfasdf" -W "abcd"
Invalid WEP key 'abcd'

Memory leak reported by Valgrind when running wlantest as mentioned above.

22828b6dba wlantest: Fix PMK length and passphrase-based key derivation for FT
The change to support variable length PMK in wlantest missed couple of
places where the PMK length did not get used or set properly. In
particular, this ended up breaking FT key derivation for the case where
a passphrase was used to derive a potential per-BSS PMK. Fix this by
setting and using the PMK length properly.

73f65cc6c4 wlantest: Support HT Control field in QoS Data frames
Extend Data frame processing (and decryption) to handle +HTC frames by
skipping the HT Control field at the end of the frame header. While this
is not an exact match of the rules in IEEE Std 802.11-2020 for when the
HT Control field is present in frames (e.g., no check of the TXVECTOR
value), this is good enough to cover the most likely used cases.

87098d3324 build: Put archive files into build/ folder too
This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).

Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.

Note that due to the use of thin archives, this required
building with absolute paths.

722138cd25 build: Put object files into build/ folder
Instead of building in the source tree, put most object
files into the build/ folder at the root, and put each
thing that's being built into a separate folder.

This then allows us to build hostapd and wpa_supplicant
(or other combinations) without "make clean" inbetween.

For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.

new length since p is already pointing to one past the last octet of the
