These were somewhat more hidden to avoid direct use, but there are now

this avoids some warnings from sparse.

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

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

the current known PTK fails to decrypt a frame (or if no current PTK is

Some corner cases may result in both directions of TDLS tracking context

The new -n<file> command line argument can be used to request wlantest

When using DLT_IEEE802_11 datalink type in a pcap file, wlantest can now

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.
