- Any scanning currently updates the bss table held by supplicant anyway,
but the time record used to maintain the recency of the last scan is
only updated by supplicant issued scans. Updating the last scan time
for application trigerred scanning will prevent the needless scanning
by supplicant if there has been an application trigerred scan in
the time diff threshold(currently 10s).
- Add default durations to supplicant issued scans based on results from
initial experiments where probe response times were recorded in a
significantly noisy environment. It was noticed that within 70ms
we receive over 80% of the responses 90% of the time
- Clear the bssid set flag and channel in supplicant disconnect handler as this
can cause the station to recursively connect to the wrong AP in case
roaming through BTM mechanisms fails.
- Fix issue with incorrect blocking time calculation when blocking scan
issued for a single channel.
- Deprecate the existing esp_rrm_send_neighbor_rep_request() API
- Adds a new API to send neighbor report requests esp_rrm_send_neighbor_report_request().
This replaces the older API's callback procedure with a new Wi-Fi
event that is posted when the neighbor report is received.
This moves the execution of the callback from supplicant
context to freertos context.
- Avoid downgrading TLS ciphersuites when client RSA keys are larger than RSA-2048 bit.
- Note that when using bigger certificates on low-power chips without crypto
hardware acceleration, it is recommended to adjust the task watchdog timer (TWDT)
if it is enabled. For precise information on timing requirements, you can check
performance numbers at https://github.com/espressif/mbedtls/wiki/Performance-Numbers.
Taking sizeof(ptr) is incorrect to determine size of passed in hash and
results in hlen getting set to a very large value since MD5_MAC_LEN >
sizeof(ptr). Provide the actual size of the hash buffer from the caller
to fix this.
tls_key_x_server_params_hash() callers src/tls/tlsv1_client_read.c and
src/tls/tlsv1_server_write.c both pass in a large enough hash (hash[64]
or hash[100]) that this does not appear to have an impact, though it is
still wrong.

Some of the TLS library wrappers defined only an empty function for

TLS server cases, so update these to do the minimal thing and free the

EAP peer does not expect data present when beginning the Phase 2 in
EAP-{TTLS,PEAP} but in TLS 1.3 session tickets are sent after the
handshake completes.
There are several strategies that can be used to handle this, but this
patch picks up from the discussion[1] and implements the proposed use of
SSL_MODE_AUTO_RETRY. SSL_MODE_AUTO_RETRY has already been enabled by
default in OpenSSL 1.1.1, but it needs to be enabled for older versions.
The main OpenSSL wrapper change in tls_connection_decrypt() takes care
of the new possible case with SSL_MODE_AUTO_RETRY for
SSL_ERROR_WANT_READ to indicate that a non-application_data was
processed. That is not really an error case with TLS 1.3, so allow it to
complete and return an empty decrypted application data buffer.
EAP-PEAP/TTLS processing can then use this to move ahead with starting
Phase 2.

EAP-TLS with TLS 1.3 uses an empty application data record from the
server to indicate end of the exchange, so EAP-TLS peer will need to
check for this special case and finish the exchange with an empty

Allow an additional context value to be passed to TLS exporter as
specified in RFC 5705 section 4.
This does not yet implement it for the internal TLS implementation.
However, as currently nothing uses context yet, this will not break
anything right now. WolfSSL maintainers also stated that they are not
going to add context support yet, but would look into it if/when this is
required by a published draft or a standard.

Derive EMSK when using EAP-PEAP to enable ERP. In addition, change the
MSK derivation for EAP-PEAP to always derive 128 octets of key material

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.

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
