Track PMK-R0/PMK-R0-Name from the initial mobility domain association
and derive PMK-R1/PTK when the station uses FT protocol. This allows
frames from additional roaming cases to be decrypted.

This allows a separate machine credential to be used for authentication
if the server requests Identity-Type = 2 (machine).
Signed-off-by: Jouni Malinen <j@w1.fi>
This is an initial step in adding support for configuring separate user
and machine credentials. The new wpa_supplicant network profile
parameters machine_identity and machine_password are similar to the
existing identity and password, but explicitly assigned for the purpose
of machine authentication.
This commit alone does not change actual EAP peer method behavior as
separate commits are needed to determine when there is an explicit
request for machine authentication. Furthermore, this is only addressing
the username/password credential type, i.e., additional changes
following this design approach will be needed for certificate
credentials.

Wait for hostapd to report completion of connection so that the WNM
Notification Request frame does not get sent before the AP has processed
EAPOL-Key msg 4/4 and configured the TK. This could result in a race
condition especially when testing using UML with time-travel.

This is needed with the increased maximum EAP round limit since the
server side sends out longer messages in this exchange and that prevent
the short message limit from being reached.
Signed-off-by: Jouni Malinen <j@w1.fi>
Allow 100 rounds of EAP messages if there is data being transmitted.
Keep the old 50 round limit for cases where only short EAP messages are
sent (i.e., the likely case of getting stuck in ACK loop).
This allows larger EAP data (e.g., large certificates) to be exchanged
without breaking the workaround for ACK loop interop issues.

Use struct eap_config as-is within struct eap_sm and EAPOL authenticator
to avoid having to duplicate all the configuration variables at each
interface. Split the couple of session specific variables into a
separate struct to allow a single const struct eap_config to be used.

The new eap_teap_separate_result=1 hostapd configuration parameter can
be used to test TEAP exchange where the Intermediate-Result TLV and
Crypto-Binding TLV are send in one message exchange while the Result TLV
exchange in done after that in a separate message exchange.
Signed-off-by: Jouni Malinen <j@w1.fi>
If the Crypto-Binding TLV for the last EAP method has been validated
successfully in a previous message exchange with Intermediate-Result TLV
and no new EAP method has been started, Result TLV can be accepted
without an additional Crypto-Binding TLV. This allows the server to go
through additional message exchanges after inner EAP method, if needed.

It is not sufficient for the peer to include only the Result TLV if the
server included both the Intermediate-Result TLV and Result TLV.

Previously, only the Result TLV was added when writing Crypto-Binding
TLV response. This is not sufficient, since RFC 7170 require

This is needed for the drivers implementing SME to include the PMKID in

pending_bssid is cleared in the connected state and thus is not valid if
SAE authentication is done to a new BSSID when in the connected state.
Hence use the BSSID from ext_auth_bssid while configuring the PMK for
the external authentication case. This is required for roaming to a new
BSSID with driver-based-SME while the SAE processing happens with
wpa_supplicant.

A new DH public key is sent through this interface to the driver after
every successful connection/roam to a BSS. This helps to do OWE roaming
to a new BSS with drivers that implement SME/MLME operations during
roaming.
This updated DH IEs are added in the subsequent (Re)Association Request
frame sent by the station when roaming. The DH IE from the roamed AP is
given to wpa_supplicant in the roam result event. wpa_supplicant shall
further process these DH IEs to generate the PMK for the 4-way
handshake.
