The AMPE element includes number of optional and variable length fields
and those cannot really be represented by a fixed struct
ieee80211_ampe_ie. Remove the optional fields from the struct and
build/parse these fields separately.
This is also adding support for IGTKdata that was completely missing
from the previous implementation. In addition, Key RSC for MGTK is now
filled in and used when configuring the RX MGTK for a peer.

Add FTM range request via RRM. The AP sends Radio measurement request
with FTM range request as a request for the receiving STA to send FTM
requests to the given list of APs. The neighbor report part of the
request is taken from the neighbor database.
The control interface command is:
REQ_RANGE <dst addr> <rand_int> <min_ap> <responder> [<responder>..]
dst addr: MAC address of an associated STA
rand_int: Randomization Interval (0..65535) in TUs
min_ap: Minimum AP Count (1..15); minimum number of requested FTM ranges
between the associated STA and the listed APs
responder: List of BSSIDs for neighboring APs for which a measurement
is requested

IEEE Std 802.11-2012 11.3.5.4 specifies the PMKID for SAE-derived keys
as:
L((commit-scalar + peer-commit-scalar) mod r, 0, 128)
This is already calculated in the SAE code when the PMK is derived, but
not saved anywhere. Later, when generating the PMKID for plink action
frames, the definition for PMKID from 11.6.1.3 is incorrectly used.
Correct this by saving the PMKID when the key is generated and use it
subsequently.

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

wpa_insert_pmkid() did not support cases where the original RSN IE
included any PMKIDs. That case can happen when PTK rekeying through
4-way handshake is used after FT protocol run. Such a 4-way handshake
used to fail with wpa_supplicant being unable to build the EAPOL-Key msg
2/4.
Fix this by extending wpa_insert_pmkid() to support removal of the old
PMKIDs, if needed.

This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.
The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)
