Operating Channel Validation (OCV) is a security feature designed to
prevent person-in-the-middle multi-channel attacks. Compile the -basic and
-full variants of hostapd with this feature, and enable discovery of this
feature for future luci integration. OCV can be configured by setting ocv
equal to one of the following values in the wireless config:
0 = disabled (hostapd/wpa_supplicant default)
1 = enabled
2 = enabled in workaround mode - Allow STA that claims OCV capability to
connect even if the STA doesn't send OCI or negotiate PMF.

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

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.

In the aftermath of the KRACK attacks, hostapd gained an AP-side workaround
against WNM-Sleep Mode GTK/IGTK reinstallation attacks. WNM Sleep Mode is not
enabled by default on OpenWrt, but it is configurable through the option
wnm_sleep_mode. Thus, make the AP-side workaround configurable as well by
exposing the option wnm_sleep_mode_no_keys. If you use the option
wpa_disable_eapol_key_retries and have wnm_sleep_mode enabled, you might

Currently, EAPOLv2 (802.1X-2004) is used by default for legacy clients that
are not WPA2 (RSN) capable. These legacy clients are often intolerant to this
EAPOL version and fail to connect.
hostapd.conf upstream documents for eapol_version the following and that this
is a known compatibility issue with version 2:
// IEEE 802.1X/EAPOL version
// hostapd is implemented based on IEEE Std 802.1X-2004 which defines EAPOL
// version 2. However, there are many client implementations that do not handle
// the new version number correctly (they seem to drop the frames completely).
// In order to make hostapd interoperate with these clients, the version number
// can be set to the older version (1) with this configuration value.
// Note: When using MACsec, eapol_version shall be set to 3, which is
// defined in IEEE Std 802.1X-2010.
//eapol_version=2
For the wpa parameter, hostapd.conf upstream documents that this is a bitfield,
configured as follows:
// Enable WPA. Setting this variable configures the AP to require WPA (either
// WPA-PSK or WPA-RADIUS/EAP based on other configuration). For WPA-PSK, either
// wpa_psk or wpa_passphrase must be set and wpa_key_mgmt must include WPA-PSK.
// Instead of wpa_psk / wpa_passphrase, wpa_psk_radius might suffice.
// For WPA-RADIUS/EAP, ieee8021x must be set (but without dynamic WEP keys),
// RADIUS authentication server must be configured, and WPA-EAP must be included
// in wpa_key_mgmt.
// This field is a bit field that can be used to enable WPA (IEEE 802.11i/D3.0)
// and/or WPA2 (full IEEE 802.11i/RSN):
// bit0 = WPA
// bit1 = IEEE 802.11i/RSN (WPA2) (dot11RSNAEnabled)
// Note that WPA3 is also configured with bit1 since it uses RSN just like WPA2.
// In other words, for WPA3, wpa=2 is used the configuration (and
// wpa_key_mgmt=SAE for WPA3-Personal instead of wpa_key_mgmt=WPA-PSK).
//wpa=2
For client compatibility therefore:
EAPOLv1 (802.1X-2001) should be used by default where WPA is enabled.
EAPOLv2 (802.1X-2004) should be used by default where WPA is disabled.
To fix this, we can therefore change in the script:
set_default eapol_version 0
To the following:
set_default eapol_version $((wpa & 1))
This therefore:
1) Sets eapol_version to 1 where WPA has been enabled via wpa bit0 being set.
2) Sets eapol_version to 0 where WPA has been disabled via wpa bit0 being unset.
For usual configurations that only have WPA2 enabled, EAPOLv2 is then used.

Set legacy_rates to 0 by default to disable 802.11b data rates by default.
The time has long come where 802.11b DSSS/CCK data rates should be disabled
by default in OpenWRT. Users in need of 802.11b client support can reasonably
enable these where they are needed.
The balance of equities has significantly, and for a long time, tipped
such that dropping backwards compatibility by default with 802.11b
devices is appropriate, proportionate and justified. By doing so,
management and control traffic is moved by default to a 20
MHz wide 6 Mb/s OFDM data rate instead of a 22 MHz wide 1 Mb/s DSSS data
rate. This is significantly more airtime efficient.
Signed-off-by: Nick Lowe <nick.lowe@gmail.com>
Add a cell_density option to configure data rates for normal, high and
very high cell density wireless deployments.
The purpose of using a minimum basic/mandatory data rate that is higher
than 6 Mb/s, or 5.5 Mb/s (802.11b compatible), in high cell density
environments is to transmit broadcast/multicast data frames using less
airtime or to reduce management overheads where significant co-channel
interference (CCI) exists and cannot be avoided.
Caution: Without careful design and validation, configuration of a too
high minimum basic/mandatory data rate can sacrifice connection stability
or disrupt the ability to reliably connect and authenticate for little to
no capacity benefit. This is because this configuration affects the
ability of clients to hear and demodulate management, control and
broadcast/multicast data frames.
Deployments that have not been specifically designed and validated are
usually best suited to use 6, 12 and 24 Mb/s as basic/mandatory data
rates.
Only usually seek to configure a 12 Mb/s, or 11 Mb/s (802.11b
compatible), minimum basic/mandatory rate in high cell density
deployments that have been designed and validated for this.
For many deployments, the minimum basic/mandatory data rate should not be
configured above 12 Mb/s to 18 Mb/s, 24 Mb/s or higher. Such a
configuration is only appropriate for use in very high cell density
deployment scenarios.
A cell_density of Very High (3) should only be used where a deployment
has a valid use case and has been designed and validated specifically for
this use, nearly always with highly directional antennas - an example
would be stadium deployments. For example, with a 24 Mb/s OFDM minimum
basic/mandatory data rate, approximately a -73 dBm RSSI is required to
decode frames. Many clients will not have roamed elsewhere by the time
that they experience -73 dBm and, where they do, they frequently may not
hear and be able to demodulate beacon, control or broadcast/multicast
data frames causing connectivity issues.
There is a myth that disabling lower basic/mandatory data rates will
improve roaming and avoid sticky clients. For 802.11n, 802.11ac and
802.11ax clients this is not correct as clients will shift to and use
lower MCS rates and not to the 802.11b or 802.11g/802.11a rates that are
able to be used as basic/mandatory data rates.
There is a myth that disabling lower basic/mandatory data rates will
ensure that clients only use higher data rates and that better
performance is assured. For 802.11n, 802.11ac and 802.11ax clients this
is not correct as clients will shift around and use MCS rates and not the
802.11b or 802.11g/802.11a rates that able to be used as basic/mandatory
data rates.
Cell Density
0 - Disabled (Default)
Setting cell_density to 0 does not configure data rates. This is the
default.
1 - Normal Cell Density
Setting cell_density to 1 configures the basic/mandatory rates to 6, 12
and 24 Mb/s OFDM rates where legacy_rates is 0. Supported rates lower
than the minimum basic/mandatory rate are not offered.
Setting cell_density to 1 configures the basic/mandatory rates to the 5.5
and 11 Mb/s DSSS rates where legacy_rates is 1. Supported rates lower
than the minimum basic/mandatory rate are not offered.
2 - High Cell Density
Setting the cell_density to 2 configures the basic/mandatory rates to the
12 and 24 Mb/s OFDM rates where legacy_rates is 0. Supported rates lower
than the minimum basic/mandatory rate are not offered.
Setting the cell_density to 2 configures the basic/mandatory rates to the
11 Mb/s DSSS rate where legacy_rates is 1. Supported rates lower than the
minimum basic/mandatory rate are not offered.
3 - Very High Cell Density
Setting the cell_density to 3 configures the basic/mandatory rates to the
24 Mb/s OFDM rate where legacy_rates is 0. Supported rates lower than the
minimum basic/mandatory rate are not offered.
Setting the cell_density to 3 only has effect where legacy_rates is 0,
else this has the same effect as being configured with a cell_density of 2.
Where specified, the basic_rate and supported_rates options continue to
override both the cell_density and legacy_rates options.
