SIGNAL_MONITOR THRESHOLD=DD HYSTERESIS=DD command will request signal
strength monitoring events based on there having been requested amount
of drop in the signal strength. The threshold value is the RSSI
threshold in dBm for the event to be sent. 0 threshold can be used to
disable monitoring. The hysteresis value is RSSI hysteresis in dB to
specify the minimum amount of change before a consecutive event is
reported.
With nl80211 driver interface, these values map to the
NL80211_CMD_SET_CQM command with NL80211_ATTR_CQM_RSSI_THOLD and
NL80211_ATTR_CQM_RSSI_HYST attributes to the driver.
This command cannot be used when bgscan module is in use since that
depends on being able to control the connection monitoring parameters.

During the sequence of exchanging GAS frames with the AP, the AP can
request to come back in X amount of time and resend the GAS request.
Previously, wpa_supplicant did not terminate the remain-on-channel
session, but rather waited until the requested comeback delay had
expired, and then tried to send the GAS frame (potentially to save the
time that is required to schedule a new remain on channel flow).
This might cause unnecessary idle time (can be close to 1000 ms) in
which the device might be off-channel. Ending the current
remain-on-channel session and then rescheduling makes better usage of
the time in this case.
End remain-on-channel session due to receiving a delayed GAS comeback
request from the AP.

wpa_ctrl_command_sta(), called by the "ALL_STA" handler, didn't consider
ifname_prefix, resulting in various commands being sent to the global
control interface, rather than the specified interface when IFNAME=
prefix was used.
This in turn caused the unexpected "UNKNOWN COMMAND" result be
considered as valid station, resulting in infinite loop while trying to
get all stations.
Fix it by considering ifname_prefix, similarly to _wpa_ctrl_command().

Previously, when wpa_supplicant received bgscan results with a preferred
network, it connected to that network without disconnecting from the
previous one. This might result in an inconsistent state of upper
layers.
Fix this by disconnecting from the current AP before connecting to the
new one when the network profile changes and there is an existing
connection.

If scan results arrive during the connection process, the network
selection function was called, interrupting the current connection.
While a regular scan is mutually exclusive with connection establishment
via the nature of radio work, there's no such protection for scheduled
scan. Prevent network selection while a connection is in progress.

This patch fixes an issue with an invalid phase2 parameter value
auth=MSCHAPv2 getting interpreted as auth=MSCHAP (v1) which could
degrade security (though, only within a protected TLS tunnel). Now when
invalid or unsupported auth= phase2 parameter combinations are
specified, EAP-TTLS initialization throws an error instead of silently
doing something.
More then one auth= phase2 type cannot be specified and also both auth= and
autheap= options cannot be specified.
Parsing phase2 type is case sensitive (as in other EAP parts), so phase2
parameter auth=MSCHAPv2 is invalid. Only auth=MSCHAPV2 is correct.

The full VHT channel information was not set in the hostapd data
structures which resulted in incorrect information (all zeros) being
used when building the VHT Operation element for peering messages while
the actual driver mode was set with the full details. We did not seem to
use the VHT information from peering messages, so this does not change
behavior with another wpa_supplicant-based mesh implementation. Anyway,
these elements should match the ones used in Beacon frames.

The decrypted copy of a GTK from EAPOL-Key is cleared from memory only
after having sent out CTRL-EVENT-CONNECTED. As such, there was a race
condition on the test case reading the wpa_supplicant process memory
after the connection. This was unlikely to occur due to the one second
sleep, but even with that, it would be at least theorically possible to
hit this race under heavy load (e.g., when using large number of VMs to
run parallel testing). Avoid this by running a PING command to make sure
wpa_supplicant has returned to eloop before reading the process memory.
This should make it less likely to report false positives on GTK being
found in memory.

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.
