e7160bd8fe Drop any pending EAPOL RX frame when starting a new connection
Such a pending frame cannot be valid anymore, so drop it instead of
risking of using an unexpected EAPOL frame after association if a
previous association received one at the end and the new association can
happen within 100 ms.

3c108b7573 EAP peer: External server certificate chain validation
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.

d38c7be0f0 Skip SELECT_NETWORK steps only if already connected or connecting
Commit 2a6f78fbbe ('Do not re-associate on
SELECT_NETWORK to current network') started skipping all SELECT_NETWORK
connection steps if the selected network had already been selected
previously. This happened regardless of whether the connection was
already established. This is not necessarily desirable for all cases
where there is no immediate action to even try to connect (e.g., long
wait for the next scan).

Speed this up by allowing the SELECT_NETWORK operation to get started if
there is no connection or ongoing connection attempt with the selected
network.

a8412ec9d0 Clear own_disconnect_req on new connection attempt
It was possible for wpa_s->own_disconnect_req to be left set to 1 from a
disconnection attempt from a prior connection. This could then prevent
proper connection failure processing with the new connection in
wpas_connection_failed(). This was triggered by the following hwsim test
case sequence: wpas_mesh_secure sae_no_ffc_by_default. In this sequence,
the SAE failure due to unsupported group did not result in proper
wpas_connection_failed() processing and retry.

Fix this by clearing wpa_s->own_disconnect_req in
wpa_supplicant_associate() before starting a new connection.

5a1d9d1a8e Avoid reconnection on ENABLE_NETWORK if already connected
This was already the case for most command sequences, but it was
possible for wpa_s->reassociate to be set to 1 when CTRL-RSP-* commands
were used to set identity, password, or passphrase for EAP
authentication. In such cases, ENABLE_NETWORK issued after the
connection was completed could result in a new connection attempt
(likely reconnection back to the same BSS).

Fix this by checking whether an actual connection is already present
even if wpa_s->reassociate is set when processing the ENABLE_NETWORK
command.

e66bcedd3e Do not set own_disconnect_req flag if not connected
This fixes some issues where a disconnection event may get ignored if an
earlier operation to remove or disable a network resulted in an attempt
to disconnect event though no connection was in place.
wpa_s->current_ssid != NULL alone is not sufficient to determine that
there will be a driver event notifying completion of such disconnection
request. Set own_disconnect_req to 1 only if wpa_s->wpa_state is also
indicating that there is a connection or an attempt to complete one.

This showed up in a failure, e.g., when running the hwsim test case
scan_int followed by ap_vlan_wpa2_psk_radius_required where the latter
ended up not processing a connection failure event and getting stuck not
trying to run a new scan and connection attempt.

4d3be9cdd1 Postpone updating of wpa_s->current_bss till association event

restored if the driver decides to "return" to the current BSS instead.
This could result in some operations (e.g., WNM BSS TM response) not

5add410162 WPS: Use shorter authentication timeout during no-SelReg iteration
When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.
