f3eb998e7e hostapd: in AP/STA, shut down AP interfaces when STA enters scanning state
When the STA is brought up, it is set to DISABLED before adding the bss to ucode,
so the first trigger to disable the AP is missed.

hostapd: always use sae_password for mesh/SAE auth
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.

09ea1db93b hostapd: rename hostapd multicast_to_unicast option to multicast_to_unicast_all
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

hostapd: add ppsk option (private psk)
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

98d91e4d5e hostapd: Radius based VLANs on AP with PSK
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.

e8d048c5e0 hostapd: SAE - Enable hunting-and-pecking and H2E
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.

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

69ce75fb12 hostapd: add fallback for WPS on stations
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.
