ced15c8ba8 wlantest: TKIP frame reassembly for Michael MIC check in fragmented case
Reassemble the full MSDU when processing TKIP protected fragmented
frames so that the Michael MIC can be validated once the last fragment
has been received.

3332657d69 wlantest: Report decrypted TKIP frames even if cannot check Michael MIC
This can be useful for debugging, so return successfully decrypted TKIP
frame even if the Michael MIC cannot be verified (fragment reassembly
not yet supported) or if the Michael MIC value is incorrect. Add a note
in the frame to point out that the Michael MIC was not verified or is
incorrect.

a1f11e34c4 Use os_memdup()
This leads to cleaner code overall, and also reduces the size
of the hostapd and wpa_supplicant binaries (in hwsim test build
on x86_64) by about 2.5 and 3.5KiB respectively.

The mechanical conversions all over the code were done with
the following spatch:

    @@
    expression SIZE, SRC;
    expression a;
    @@
    -a = os_malloc(SIZE);
    +a = os_memdup(SRC, SIZE);
    <...
    if (!a) {...}
    ...>
    -os_memcpy(a, SRC, SIZE);

e2991ee580 Move CRC-32 routine from wlantest to src/utils
This allows the CRC-32 routine to be shared for other purposes in
addition to the WEP/TKIP/FCS within wlantest.
