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.

Provide incoming BSS transition queries to ubus subscribers.
This allows external steering daemons to provide clients with
an optimal list of transition candidates.
This commit has no functional state in case no ubus subscriber is

If authentication fails repeatedly e.g. because of a weak signal, the link
can end up in blocked state. If one of the nodes tries to establish a link
again before it is unblocked on the other side, it will block the link to
that other side. The same happens on the other side when it unblocks the
link. In that scenario, the link never recovers on its own.
To fix this, allow restarting authentication even if the link is in blocked
state, but don't initiate the attempt until the blocked period is over.

When procd-ujail is available, 1f785383875a runs hostapd as user
"network", with only limited additional capabilities (CAP_NET_ADMIN and
CAP_NET_RAW).
hostapd_cli (CONFIG_PACKAGE_hostapd-utils) communicates with hostapd
over a named UNIX-domain socket. hostapd_cli is responsible for creating
this socket at /tmp/wpa_ctrl_$pid_$counter. Since it typically runs as
root, this endpoint is normally created with uid root, gid root, mode
0755. As a result, hostapd running as uid network is able to receive
control messages sent through this interface, but is not able to respond
to them. If debug-level logging is enabled (CONFIG_WPA_MSG_MIN_PRIORITY
<= 2 at build, and log_level <= 2 in /etc/config/wireless wifi-device),
this message will appear from hostapd:
CTRL: sendto failed: Permission denied
As a fix, hostapd_cli should create the socket node in the filesystem
with uid network, gid network, mode 0770. This borrows the presently
Android-only strategy already in hostapd intended to solve the same
problem on Android.
If procd-ujail is not available and hostapd falls back to running as
root, it will still be able to read from and write to the socket even if
the node in the filesystem has been restricted to the network user and
group. This matches the logic in
package/network/services/hostapd/files/wpad.init, which sets the uid and
gid of /var/run/hostapd to network regardless of whether procd-ujail is
available.
As it appears that the "network" user and group are statically allocated
uid 101 and gid 101, respectively, per
package/base-files/files/etc/passwd and USERID in
package/network/services/hostapd/Makefile, this patch also uses a
constant 101 for the uid and gid.

19aae94 [build: avoid rebuilds of unset VARIANT packages] builds
packages defined without a VARIANT only once, using the first VARIANT
defined in the Makefile.
This caused problems with wpa-cli, as it is only built for variants that
include supplicant support, and the first VARIANT defined may not build
it.
The same happens to hostapd-utils, which is not built for
supplicant-only variants.
To circumvent this, set VARIANT=* for both packages so that they get
built for every defined variant. This should not cause spurious
rebuilds, since tey are not a dependency of any other package defined in
this Makefile.

Package hostapd-common is a dependency of every other package defined in
hostpad Makefile. It is currently built next to the bottom of that
Makefile's package list.
If you run make back to back, then check-compile will compare the
hostapd-common timestamp to the variant being compiled, to decide if the
varint needs to be rebuilt or not. Since the hostapd-conf package is
built towards the end of the list, it will be newer than most of the
variants, causing unnecessary package rebuilds.
Move it to the top, so that its timestamp will be older than dependent
packages, avoiding unnecessary rebuild of every selected variant.

The existing wnm_disassoc_imminent ubus method only supports issuing a
bss transition request with the disassoc imminent flag set.
For use-cases, where the client is requested to roam to another BSS
without a pending disassoc, this existing method is not suitable.
Add a new bss_transition_request ubus method, which provides a more
universal way to dispatch a transition request. It takes the following
arguments:
Required:
addr: String - MAC-address of the STA to send the request to (colon-seperated)
Optional:
abridged - Bool - Indicates if the abridged flag is set
disassociation_imminent: Bool - Whether or not the disassoc_imminent
flag is set
disassociation_timer: I32 - number of TBTTs after which the client will
be disassociated
validity_period: I32 - number of TBTTs after which the beacon
candidate list (if included) will be invalid
neighbors: blob-array - Array of strings containing neighbor reports as
hex-string
