Move to the version used in draft-ietf-emu-eap-tls13-03.txt, i.e.,
include the 0x0D prefix and use a different TLS-Exporter() label string.

The label strings used for deriving Key_Material with TLS v1.3 were
changed, so update the implementation to match the new values.

The EAP session cannot be marked fully completed on sending Client
Finished with TLS v1.3 since the server may still send NewSessionTicket
before EAP-Success.

With TLS v1.3, the Finished message from the client can require
fragmentation. Postpone key derivation and marking of the EAP session
fully completed until all the fragments of that last message are sent to
avoid losing all the subsequent fragments.

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.

Fix issues with DPP stop listen and DPP auth data deinit

Make sure that WPS registrar public APIs do not modify supplicant
data in application task context. Execute API functionlity in eloop
context to prevent protential race conditions.
Avoid dereferencing a dangling function pointer in 'eap_server_sm_deinit()'.
This issue arises when hostap unregisteres EAP methods before it removes
the server state machine for station.
The previous PEAP client behavior allowed the server to skip Phase 2
authentication with the expectation that the server was authenticated
during Phase 1 through TLS server certificate validation. Various PEAP
specifications are not exactly clear on what the behavior on this front
is supposed to be and as such, this ended up being more flexible than
the TTLS/FAST/TEAP cases. However, this is not really ideal when
unfortunately common misconfiguration of PEAP is used in deployed
devices where the server trust root (ca_cert) is not configured or the
user has an easy option for allowing this validation step to be skipped.
Change the default PEAP client behavior to be to require Phase 2
authentication to be successfully completed for cases where TLS session
resumption is not used and the client certificate has not been
configured. Those two exceptions are the main cases where a deployed
authentication server might skip Phase 2 and as such, where a more
strict default behavior could result in undesired interoperability
issues. Requiring Phase 2 authentication will end up disabling TLS
session resumption automatically to avoid interoperability issues.
Allow Phase 2 authentication behavior to be configured with a new phase1
configuration parameter option:
'phase2_auth' option can be used to control Phase 2 (i.e., within TLS
tunnel) behavior for PEAP:
* 0 = do not require Phase 2 authentication
* 1 = require Phase 2 authentication when client certificate
(private_key/client_cert) is no used and TLS session resumption was
not used (default)
* 2 = require Phase 2 authentication in all cases
1) Add parameter to configure reason code of deauth frame
2) Add logs to indicate MIC failure 4-Way-Handshake
3) Process RSNXE capabilities only if AP advertises them
