The flags that indicate that a channel is allowed for 80/160 MHz use
are divided according to the position of the control channel (e.g.,
HOSTAPD_CHAN_VHT_10_70, HOSTAPD_CHAN_VHT_30_50, etc.).
However, the position of the control channel does not add any extra
regulatory information because when trying to use a 80/160 MHz channel
all the desired bandwidth has to be allowed for 80/160 MHz use,
regardless of the control channel position.
In addition, these flags are set only if the driver reports one
regulatory rule that allows the entire 80/160 MHz bandwidth.
However, even when a 80/160 MHz channel is allowed, in some cases the
bandwidth will be split into several regulatory rules because
different segments of the bandwidth differ in other flags (that don't
affect the use of the bandwidth for VHT channels). So, in such cases
these flags will not be set, although VHT channels are allowed.
As the result, VHT channels will not be used although they are allowed
by the regulatory domain.
Fix this by introducing new flags that indicate if a 2 0MHz channel is
allowed to be used as a part of a wider (80/160 MHz) channel.
The new flags are set for each 20 MHz channel independently and thus
will be set even if the regulatory rules for the bandwidth are split.
A 80/160 MHz channel is allowed if all its 20 MHz sub-channels are
allowed for 80/160 MHz usage.

On NixOS[1] - a Linux distribution which allows to configure a full OS
declaratively - it's possible to configure SSIDs for `wpa_supplicant`
like this:
networking.wireless.networks = {
myssid = {
pskRaw = "<redacted>";
};
};
It's also possible to add networks "imperatively" using `wpa_gui` or
`wpa_cli`. However it's not possible to do both because if the first
option is used, NixOS creates a read-only symlink at
`/etc/wpa_supplicant.conf` and then it's not possible for
`wpa_supplicant` anymore to write to it.
This patch aims to help us changing this: while "declarative" SSID
configuration can be quite useful, it's a bad idea for e.g. sensitive
stuff like a WPA2 enterprise network.
The original idea was to use `-I`[2] for immutable configs (including
"declarative" networks) on NixOS and `-c /etc/wpa_supplicant.conf` for
anything "imperative".
However this doesn't really work out because if a wifi network from a
config file specified with `-I` is changed by e.g. `wpa_gui`, it's
silently overwritten in `/etc/wpa_supplicant.conf` (specified with
`-c`) which is IMHO unintuitive (in our case at least). This patch
basically declares each network defined in a config file passed via `-I`
to `wpa_supplicant` as "read-only" and doesn't write these "read-only"
networks to `/etc/wpa_supplicant.conf`.
A bit more context can be found on GitHub in the PR where I implemented
this[3].

The main difference between this policy and policy 1 is the ability to
control persistence of the MAC address used. For example if there is
a requirement to always use the same (but random) MAC address for given
SSID (even if user removes/forgets the network) this could be handled
outside of the wpa_supplicant by using some SSID based hashing scheme to
generate MAC (or by just storing the randomly generated one) and
providing it to wpa_supplicant together with mac_addr=3 policy.

In case of drivers supporting 4-way handshake offload, mark port
authorized and state completion only if the driver advertizes authorized
state in the connect event. Otherwise there are fair chances of the
driver port authorization API getting called while 4-way handshake is in
progress at the lower layer.
In order to avoid this possible race condition always update port
authorization and supplicant state WPA_COMPLETED setting from
EVENT_PORT_AUTHORIZED context when the driver is done with the 4-way
handshake.

UUID-E is needed since that is not available in the Beacon frame.

If a higher priority BSS has invalid security parameters, e.g., an
invalid SAE password, and a lower priority BSS is discovered only after
the local network profile has been temporarily disabled, the BSSID
ignoring mechanism is not sufficient to allow the lower priority BSS to
be tried and all consecutive attempts will continue to use the higher
priority BSS. This might prevent connection in some unexpected cases
with invalid network configuration.
Extend BSSID ignoring mechanism to work in this type of a case by
ignoring the BSSID that resulted in disabling the SSID temporarily
during the first connection attempt after having re-enabled the SSID.
This allows a lower priority BSS, if any is available in scan results,
to be tried next to see if it might have working security parameters.

wpa_supplicant has support for only a single FT key hierarchy and as
such, cannot use more than a single mobility domain at a time. Do not
allow FT protocol to be started if there is a request to reassociate to
a different BSS within the same ESS if that BSS is in a different
mobility domain. This results in the initial mobility domain association
being used whenever moving to another mobility domain.
While it would be possible to add support for multiple FT key hierachies
and multiple mobility domains in theory, there does not yet seem to be
sufficient justification to add the complexity needed for that due to
limited, if any, deployment of such networks. As such, it is simplest to
just prevent these attempts for now and start with a clean initial
mobility domain association.

Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher

to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.

are configured with ieee80211w=3 (default) and key_mgmt="WPA-PSK SAE".
In this configuration if the device is unable to use PMF due to
lacking BIP group ciphers it will avoid SAE and fallback to
