Add an UCI option to enable Multiple BSSID Advertisement. Enabling this
will announce all BSSIDS on a phy in a single beacon frame. The
interface that is brought up first will be the transmitting profile, all
others are non-transmitting profiles and will be advertised in the
Multiple BSSID element in Beacon and Probe Response frames of the first
interface.
This depends on driver and client support. Enabling this will result in
all but the first interface not being visible at all for clients that do
not support it.

This patch fixes a corner case when using passwords that are exactly 64
characters in length with mesh mode or passwords longer than 63 characters
with SAE because 'psk' is used instead of 'sae_password'.
SAE is obligatory for 802.11s (mesh point).
The 'psk' option for hostapd is suited for WPA2 and enforces length
restrictions on passwords. Values of 64 characters are treated as PMKs.
With SAE, PMKs are always generated during the handshake and there are no
length restrictions.
The 'sae_password' option is more suited for SAE and should be used
instead.
Before this patch, the 'sae_password' option is only used with mesh mode
passwords that are not 64 characters long.
As a consequence:
- mesh passwords can't be 64 characters in length
- SAE only works with passwords with lengths >8 and <=63 (due to psk
limitation).
Fix this by always using 'sae_password' with SAE/mesh and applying the PMK
differentiation only when PSK is used.

There are two feature currently altered by the multicast_to_unicast option.
1. bridge level multicast_to_unicast via IGMP snooping
2. hostapd/mac80211 config multicast_to_unicast setting
The hostapd/mac80211 setting has the side effect of converting *all* multicast
or broadcast traffic into per-station duplicated unicast traffic, which can
in some cases break expectations of various protocols.
It also has been observed to cause ARP lookup failure between stations
connected to the same interface.
The bridge level feature is much more useful, since it only covers actual
multicast traffic managed by IGMP, and it implicitly defaults to 1 already.
Renaming the hostapd/mac80211 option to multicast_to_unicast_all should avoid
unintentionally enabling this feature

This PR allows a user to enable a private psk, where each station
may have it's own psk or use a common psk if it is not defined.
The private psk is defined using the sta's mac and a radius server
is required.
ppsk option should be enabled in the wireless configuration along with
radius server details. When using PPSK, the key is ignored, it will be
retrieved from radius server. SAE is not yet supported (private sae) in
hostapd.
Wireless example configuration:
option encryption 'psk2+ccmp'
option ppsk '1'
option auth_server '127.0.0.1'
option auth_secret 'radiusServerPassword'
If you want to use dynamic VLAN on PPSK also include:
option dynamic_vlan '2'
option vlan_tagged_interface 'eth0'
option vlan_bridge 'br-vlan'
option vlan_naming '0'
It works enabling mac address verification on radius server and
requiring the tunnel-password (the private psk) from radius server.
In the radius server we need to configure the users. In case of
freeradius: /etc/freeradius3/mods-config/files/authorize
The user and Cleartext-Password should be the mac lower case using the
format "aabbccddeeff"
<sta mac> Cleartext-Password := "<sta mac>"
Tunnel-Password = <Private Password>
Example of a user configured in radius and using dynamic VLAN5:
8cb84a000000 Cleartext-Password := "8cb84a000000"
Tunnel-Type = VLAN,
Tunnel-Medium-Type = IEEE-802,
Tunnel-Private-Group-ID = 5,
Tunnel-Password = MyPrivPw
If we want to have a default or shared psk, used when the mac is not
found in the list, we need to add the following at the end of the radius
authorize file:
DEFAULT Auth-Type := Accept
Tunnel-Password = SharedPw
And if using VLANs, for example VLAN6 for default users:
DEFAULT Auth-Type := Accept
Tunnel-Type = VLAN,
Tunnel-Medium-Type = IEEE-802,
Tunnel-Private-Group-ID = 6,
Tunnel-Password = SharedPw

This patch allows the user to set `auth_server` and related settings on
non WPA2 Enterprise AP modes in `/etc/config/wireless`, too, so the
Radius Attributes for Dynamic VLAN Assignment can be fetched from Radius.
Without this patch, `auth_server` and other needed options are only
written to `hostapd-phy<n>.conf` when `option encryption wpa2` is set.
`hostapd` however supports "Station MAC address -based authentication" for
non WPA Enterprise Modes, too.
A classic approch is to use `accept_mac_file` which contains MAC addr
and VLAN-ID pairs. But, using `accept_mac_file` does not support
VLAN assignment for unknown stations.
This is a sample `freeradius3` config, where a known station
("7e:a6:a7:2a:93:d2") is assigned to VLAN `65` and unknown stations are
assigned to VLAN `67`.
```
"7ea6a72a93d2" Cleartext-Password := "7ea6a72a93d2"
Tunnel-Type = "VLAN",
Tunnel-Medium-Type = "IEEE-802",
Tunnel-Private-Group-Id = 65
DEFAULT Cleartext-Password := "%{User-Name}"
Tunnel-Type = "VLAN",
Tunnel-Medium-Type = "IEEE-802",
Tunnel-Private-Group-Id = 67
```
Other option is to configure known stations via `accept_mac_file` and
using only Radius for unknown stations.
I tested this patch only with `wpa_key_mgmt=WPA-PSK`, and assumed that
it should work with other Encryption/Access Mode, too.

Enable both the hunting-and-pecking loop and hash-to-element mechanisms
by default in OpenWRT with SAE.
Commercial Wi-Fi solutions increasingly frequently now ship with both
hunting-and-pecking and hash-to-element (H2E) enabled by default as this
is more secure and more performant than offering hunting-and-pecking
alone for H2E capable clients.
The hunting and pecking loop mechanism is inherently fragile and prone to
timing-based side channels in its design and is more computationally
intensive to perform. Hash-to-element (H2E) is its long-term
replacement to address these concerns.
For clients that only support the hunting-and-pecking loop mechanism,
this is still available to use by default.
For clients that in addition support, or were to require, the
hash-to-element (H2E) mechanism, this is then available for use.

The 80211r r0kh and r1kh defaults are generated from the md5sum of
"$mobility_domain/$auth_secret". auth_secret is only set when using EAP
authentication, but the default key is used for SAE/PSK as well. In
this case, auth_secret is empty, and the default value of the key can
be computed from the SSID alone.
Fallback to using $key when auth_secret is empty. While at it, rename
the variable holding the generated key from 'key' to 'ft_key', to avoid
clobbering the PSK.

Up to now the WPS script triggered WPS on the stations only if it
could not trigger it successfully on any hostapd instance.
In a Multi-AP context, there can be a need (to establish a new
wireless backhaul link) to trigger WPS on the stations, regardless of
whether there is already a hostapd instance configured or not. The
current script makes it impossible, as if hostapd is running and
configured, WPS would always be triggered on hostapd only.
To allow both possibilities, the following changes are made:
- Change the "pressed" action to "release", so that we can make use of
the "$SEEN" variables (to know for how long the button was pressed).
- If the button is pressed for less than 3 seconds, keep the original
behavior.
- If the button is pressed for 3 seconds or more, trigger WPS on the
stations, regardless of the status of any running hostapd instance.
- Add comments explaining both behaviors.
- While at it, replace the usage of '-a' with a '[] && []'
construct (see [1]).
This gives users a "fallback" mechanism to onboard a device to a
Multi-AP network, even if the device already has a configured hostapd
instance running.

With the default configuration we generate, the supplicant starts
scanning and tries to connect to any open network when the interface
is enabled.
In some cases it can be desirable to prevent the supplicant from
scanning by itself. For example, if on the same radio an AP is
configured and an unconfigured STA is added (to be configured with
WPS), the AP might not be able to beacon until the STA stops
scanning.
In such a case, the STA configuration can still be required to set
specific settings (e.g. multi_ap_backhaul_sta) so it can't be set to
"disabled" in uci (because that would prevent the supplicant from
being run at all). The alternative is to add the "disabled" parameter
to the default network block in the supplicant configuration.
This patch adds a "default_disabled" setting in UCI which, when set,
adds the "disabled" parameter to the supplicant default network block.
