The TX event for the next frame in the sequence might be received before
the TX status for the final GAS response frame is processed. This used
to result in the Config Result getting discarded and the negotiation not
completing successfully on the Configurator side.
Accept the Config Result message as an indication of the final GAS
response frame having went through fine even if the TX status has not
yet been processed to avoid this issue from a potential race condition

When the driver SME is used, offloaded RSN handshakes like SA Query, GTK
rekeying, FT authentication, etc. would fail if wpa_supplicant enables
OCV in initial connection based on configuration but the driver doesn't

enabling OCV when the driver SME used.

It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.
Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.
This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.
With this new backend, splitting up credentials and configuration
becomes trivial:
# /etc/wpa_supplicant/wpa_supplicant.conf
ext_password_backend=file:/etc/wpa_supplicant/psk.conf
network={
ssid="foobar"
psk=ext:foobar
}
# /etc/wpa_supplicant/psk.conf
foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b
Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

The function wpa_config_get_line() is used by the wpa_supplicant config
file parser to retrieve the next non-comment non-blank line. We'll need
the same kind of functionality to implement the file-based external

function into its own standalone file in the utils package.

Number of the P2P+NFC test cases have been failing every now and then
and those failures seemed to be because of having somehow managed to
select the GO's operating channel as HT40+ on the channel 11 in the 2.4
GHz band, i.e., something that is clearly incorrect. The P2P check for
HT40 secondary channel is supported only on the 5 GHz band, so drop HT40
configuration if it shows up unexpectedly on the 2.4 GHz band to avoid
issues in GO being able to start.

There's a chance that prior to config reload being requested a scan work
was started. As such forcing wpa_supplicant to WPA_DISCONNECTED was
removing any hints that the actual driver is busy with work. That led to
wpa_supplicant reporting "Failed to initialize AP scan" over and over
again for a few seconds (depending on driver/capabilities) until the
untracked scan finished.
Cancelling a scan isn't really a solution because there's a bunch of
scanning state bits sprinkled across wpa_supplicant structure and they
get updated as driver events actually flow in in async manner.
As far as I can tell this is only preventing unnecessary warning
messages. This doesn't seem like it was crippling any logic per se.

The chirp scan could override the scan_res_handler. This could lead to
wpa_supplicant getting stuck in a scanning state while not scanning at
all until forced to, e.g., via an explicit SCAN control command.
The condition for trigerring this problem in my testing was when
(interface_count % 3) == 2. This introduced a two second delay before
actual scan was triggered after starting the wpa_supplicant instance up.
If DPP chirping was requested fast enough, in between the queueing and
triggering, it would punt the scan request, never to be resumed again.
Chirp scan handler wouldn't resume it leaving wpa_supplicant
inadvertently idle.

Currently, the external_scan_running flag is not reset when an interface
is removed. Thus, if a connection attempt is made on another iface, it
will fail due to wpa_supplicant incorrectly assuming the radio is still
busy due to the ongoing scan.
To fix this, convert external_scan_running to a pointer to the interface
that started the scan. If this interface is removed, also reset the
pointer to NULL so that other operations may continue on this radio.

1. Start scan on wlan0
2. Remove wlan0

Add support for PASN authentication with FT key derivation:
- As IEEE P802.11az/D2.6 states that wrapped data is optional and
is only needed for further validation of the FT security parameters,
do not include them in the first PASN frame.
- PASN with FT key derivation requires knowledge of the PMK-R1 and
PMK-R1-Name for the target AP. As the WPA state machine stores PMK-R1,
etc. only for the currently associated AP, store the mapping of
BSSID to R1KH-ID for each previous association, so the R1KH-ID
could be used to derive PMK-R1 and PMK-R1-Name. Do so instead
of storing the PMK-R1 to avoid maintaining keys that might not
be used.

Commit 02c21c02d0 ("wpa_supplicant: Do not disconnect on deinit if

indicates that WoWLAN is enabled. This is not the expected behavior in
some earlier use cases where the wpa_supplicant process is left running
when going to sleep and killing of the wpa_supplicant process is used
only when there is an expectation of Wi-Fi connection being disabled.
To support the use cases which require the WLAN to disconnect on deinit
even if WoWLAN is enabled, introduce a configuration parameter
wowlan_disconnect_on_deinit. This is set to 0 by default thereby not
impacting the functionality in the above mentioned commit. Setting it to
