Add support for SSID protection in 4-way handshake based on the
mechanism added in IEEE 802.11REVme/D6.0. This is a mitigation against
CVE-2023-52424 (a.k.a. the SSID Confusion Attack).
This functionality is disabled by default and can be enabled with
ssid_protection=1 in the network profile. Once there has been more
testing of this to confirm there is no significant interoperability
issues, the goal is to be able to change this to be enabled by default.

The standard is somewhat unclear on whether the PMKIDs used in

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].

Until now Hotspot 2.0 credentials were only supporting one home OI (with

required_roaming_consortium option). To improve the compliance with
Passpoint specification, add the support for multiple home and required
OIs.
The lists of OIs are provided using two new configuration options
home_ois and required_home_ois that expect a list of OIs formatted as
the roaming_consortiums list. It allows to keep the old options to avoid
breaking currently running configurations and better fits the vocabulary
used in the spec.
The OI match algorithm is updated to implement the behavior described in
Passpoint specification v3.2 section 9.1.2 (Home OIs nodes description

Add the `sae_check_mfp` global option to limit SAE when PMF will
not be selected for the connection.
With this option SAE is avoided when the hardware is not capable
of PMF due to missing ciphers.
With this option SAE is avoided on capable hardware when the AP
does not enable PMF.
Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher
necessary for PMF. This enables configurations that can fall back
to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.
Useful when `pmf=1` and `sae_check_mfp=1` are enabled and networks
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
WPA-PSK for that connection.

The id and cred_id variables are reset to 0 every time the
wpa_config_read() function is called, which is fine as long as it is
only called once. However, this is not the case when using both the -c

This is a problem because the GUI, since commit eadfeb0e93 ("wpa_gui:

(and increasing), and might get into an infinite loop otherwise.
This is solved by simply making the variables static.

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
1 restores the old behavior before the commit identified above.

This is also working around an interoperability issue of DPP R2 STA with
