According to P802.11ax/D4.0 9.4.2.238 (HE Operation element) the BSS
Color Information field is located after the HE Operation Parameters
field. Fix the ordering of the bit masks/offsets for fields in these 3+1
octets used as a single 32-bit value. With these changes, Wireshark 3.2
is able to properly parse and display Beacon frames.

IEEE P802.11ax/D4.0 9.4.2.243 "HE Operation element" indicates that the
special value 1023 in the TXOP Duration RTS Threshold field is used to
indicate that TXOP duration-based RTS is disabled. Use that value as the
default instead of the previously used value 0 which would really mean
threshold of 0 usec. Furthermore, the previous implementation did not
allow values larger than 255 to be used for this field while the field
is actually 10 bits in size.

The QCA_NL80211_VENDOR_SUBCMD_GET_HE_CAPABILITIES attributes are not
up-to-date with the latest P802.11ax/D4.0 capabilities and would need to
be updated or replaced. Since the variables from this functionality were
not used for anything in practice, it is easier to simply remove this
functionality completely to avoid issues with upcoming updates to use
upstream nl80211 information to determine HE capabilities.
This is practically reverting the commit ca1ab9db2a ("hostapd: Get
vendor HE capabilities").

These cases are for the IEEE 802.11 Status Code and Reason Code and
those fields are unsigned 16 bit values, so use the more appropriate
type consistently. This is mainly to document the uses and to make the

A DPP TCP connection can now be initiated directly from wpa_supplicant
with the new new tcp_port and tcp_addr parameters to the DPP_AUTH_INIT
control interface command. This initiates DPP Authentication exchange
over TCP with the specified Controller instead of using DPP Public
Action frames over WLAN.

New wpa_supplicant control interface commands "DPP_CONTROLLER_START
[tcp_port=<port>]" and "DPP_CONTROLLER_STOP" can be used to start and
stop listening to DPP requests over TCP in the Responder role. The TCP
connections are processed similarly to the ones that would have been
received over DPP Public Action frames.

The new hostapd configuration parameter dpp_controller can now be used
with the following subparameter values: ipaddr=<IP address>
pkhash=<hexdump>. This adds a new Controller into the configuration
(i.e., more than one can be configured) and all incoming DPP exchanges
that match the specified Controller public key hash are relayed to the
particular Controller.

Do not try to derive a PMK-R0 and PMK-R1 again for the case where an

There is no PMK/PMKID when going through 4-way handshake during an
association started with FT protocol, so need to allow the operation to
proceed even if there is no selected PMKSA cache entry in place.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
The PMK and PMKID information from FILS ERP and FILS PMKSA caching needs
to be stored within struct wpa_state_machine for PTK to work. Without
this, PTK derivation would fail and attempt to go through rekeying would
result in disconnection. Furthermore, wpa_rekey_ptk() timer needs to be
started at the completion of FILS association since the place where it
was done for non-FILS cases at the end of 4-way handshake is not reached
when FILS authentication is used.
