In theory, each device that supports WMM (or the IEEE 802.11 QoS for
that matter) is expected to advertise how many replay counters it
supports and the peer device is supposed to use that information to
restrict the total number of different MSDU priorities (AC/UP) that
might be used. In practice, this is not really done in deployed devices
and instead, it is just assumed that everyone supports the eight
different replay counters so that there is no need to restrict which
MSDU priorities can be used.
hostapd implementation of WMM has advertised support for 16 PTKSA replay
counters from the beginning while wpa_supplicant has not had any code
for setting the supported replay counter fields in RSNE, i.e., has left
the value to 0 which implies that only a single replay counter is
supported. While this does not really result in any real issues with
deployed devices, this is not really correct behavior based on the
current IEEE 802.11 standard and the WMM specification.
Update wpa_supplicant to use similar design to the hostapd RSNE
generation by setting the number of supported PTKSA replay counters to
16 whenever WMM is enabled. For now, this is done based on the
association being for HT/VHT/HE/EHT and also based on the AP supporting
WMM since it is much more likely for the local device to support WMM and
eight replay counters (which can be indicated only with the value that
implies support for 16 counters since there is no separate value for 8).

This is a step in separating RSN and WPA(v1) processing of EAPOL-Key
frames into separate functions. This allows the implementation to be
simplified and potentially allows the validation rules to be made
stricter more easily. This is also a step towards allowing WPA(v1)
functionality to be removed from the build in the future.

This test case was checking the exact key info bits in EAPOL-Key frames
during PTK rekeying as such, needs to be updated to match the
implementation change on the Secure bit setting.

The wpa_supplicant implementation for this functionality is going to be
changed to not require disconnection, so prepare the test case to not
fail.

This makes it more convenient to run tests with builds that disable

This removes dependency on tcpdump by using an already included test
tool for capturing frames with Ethernet headers. There were some issues
in getting tcpdump working on Ubuntu 19.10, so this seems to be a clean
way of addressing that.

These were doing practically the same thing, so get rid of the external

Wait for hostapd to report completion of the connection before going
through the disconnection and reconnection steps to avoid a race
condition especially with UML time-travel.

This verifies mac80211 behavior for Layer 2 Update frame use and other
unexpected frames from a not fully authentication station.

When going through 4-way handshake, the station side reports
CTRL-EVENT-CONNECTED after having sent out EAPOL-Key msg 4/4. The AP
side reports AP-STA-CONNECT after having completed processing of this
frame. Especially when using UML with time travel, it is possible for
the connectivity test to be started before the AP side has configured
the pairwise TK if the test is triggered based on CTRL-EVENT-CONNECTED
instead of AP-STA-CONNECT.
Add explicit wait for AP-STA-CONNECT in some of these cases to reduce
likelihood of reporting failures for test cases that are actually
behaving as expected. This shows up with "dev1->dev2 unicast data
delivery failed" in the test log.
Do the same before requesting reauthentication from the station side
since that has a similar issue with the EAPOL-Start frame getting
encrypted before the AP is ready for it.

Waiting for exactly one second for a one second timeout with
time-travel=inf-cpu is not exactly robust, so increase that wait to be
able to see the last EAPOL-Key TX attempt from hostapd.

Once mac80211 starts reporting the used Association Request frame IEs in
the association event, wpa_supplicant will update RSN supplicant IE
information based on that and that will make the AP reject EAPOL-Key msg
2/4 in this particular test scenario due to the hack of including two
RSN IEs in the Association Request frame. Accept this sequence as a
valid test execution in addition to the previously expected connection
to avoid reporting incorrect failures.
