When hitting a timing window where ubus configuration calls are hitting hostapd
and wpa_supplicant simultaneously, they can deadlock waiting for each other.
Fix this by using a lock around the ubus calls.

MAC address and interface name assigned by mac80211.sh depend on the order in
which interfaces are brought up. This order changes when interfaces get added
or removed, which can cause unnecessary reload churn.
One part of the fix it making MAC address allocation more dynamic in both
wpa_supplicant and hostapd, by ignoring the provided MAC address using
the next available one, whenever the config does not explicitly specify one.
The other part is making use of support for renaming netdevs at runtime and
preserving the MAC address for renamed netdevs.

When switching from a STA-only configuration to AP+STA on the same phy, the
STA was previously restarted in order to notify hostapd of the new frequency,
which might not match the AP configuration.
Fix the STA restart by querying the operating frequency from within hostapd
when bringing up the AP.

It seems that this was not functioning properly and was likely completely unused.
Keeping this out of tree also introduced some annoying churn when updating, because

The "tx_burst" option which should control the value was
expecting more of a list and hence tx_queue_data2_burst
value wasn't updated.
Yes, it would make sense to have a list for this, the
existing code only updates tx_queue_data2_burst and
not the other tx_queue_data[0134]_burst values.

It is common for 802.11ax NICs to support more than just AP mode, which
results in there being a distinct set of HE capabilities for each mode. As
(bad) luck would have it, iw prints out info for each HE mode in sequential
order according to `enum nl80211_iftype`, and AP mode isn't always first.
As a result, the wrong set of HE capabilities can be parsed if an AP NIC
supports station (managed) mode or any other mode preceding AP mode, since
only the first set of HE capabilities printed by iw is parsed from awk's
output.
This has a noticeable impact on beamforming for example, since managed mode
usually doesn't have beamformer capabilities enabled, while AP mode does.
Hostapd won't be set up with the configs to enable beamformer capabilities
in this scenario, causing hostapd to disable beamforming to HE stations
even when it's supported by the AP.
Always parse the correct set of HE capabilities for AP mode to fix this.
This is achieved by trimming all of iw's output prior to the AP mode
capabilities, which ensures that the first set of HE capabilities are
always for AP mode.

Introduce a new option background_radar to toggle hostapd's background
radar feature. Enabling this allows DFS CAC to run on dedicated radio RF
chains while the radio(s) are otherwise running normal AP activities on
other channels.
As OpenWrt configures hostapd to use a channel list even when a single
channel is configured, using this feature requires a list of channels in
/etc/config/wireless. Alternatively, channel can be set to auto.

On systems using brmcfmac (e.g. Raspberry Pi Zero W) without this fix,
the final setup-call:
iw dev wlan0 ibss join ...
fails with returncode 161 and message:
"command failed: Not supported (-95)"
So this patch calls an explicit:
iw dev wlan0 set type ibss
just prior to the 'ibss join' command.
I have tested several ath9k and mt76xx devices
with different revisions: this patch does not harm.
please also apply to stable branch.

drv_mac80211_teardown fails silently if the device to be torn down is

When wifi is turned off, drv_mac80211_teardown sometimes fails (silently)
because the device to be torn down is not defined.
This situation arises if drv_mac80211_setup was called twice when
wifi was turned on.
This commit ensures that the device to be torn down is always defined
in drv_mac80211_teardown.
Steps to reproduce:
1) Use /sbin/wifi to turn on wifi.
uci set wireless.@wifi-iface[0].disabled=0
uci set wireless.@wifi-device[0].disabled=0
uci commit
wifi
2) Use /sbin/wifi to turn off wifi.
uci set wireless.@wifi-device[0].disabled=1
uci commit
wifi
3) Observe that wifi is still up.

If drv_mac80211_setup is called twice with the same wifi configuration,
then the second call returns early with error HOSTAPD_START_FAILED.
(wifi works nevertheless, despite the fact that setup is incomplete. But
"ubus call network.wireless status" erroneously reports that radio0 is down.)
The relevant part of drv_mac80211_setup is,
if [ "$no_reload" != "0" ]; then
add_ap=1
ubus wait_for hostapd
local hostapd_res="$(ubus call hostapd config_add "{\"iface\":\"$primary_ap\", \"config\":\"${hostapd_conf_file}\"}")"
ret="$?"
[ "$ret" != 0 -o -z "$hostapd_res" ] && {
wireless_setup_failed HOSTAPD_START_FAILED
return
}
wireless_add_process "$(jsonfilter -s "$hostapd_res" -l 1 -e @.pid)" "/usr/sbin/hostapd" 1 1
fi
This commit sets no_reload = 0 during the second call of drv_mac80211_setup.
It is perhaps worth providing a way to reproduce the situation
where drv_mac80211_setup is called twice.
When /sbin/wifi is used to turn on wifi,
uci set wireless.@wifi-iface[0].disabled=0
uci set wireless.@wifi-device[0].disabled=0
uci commit
wifi
/sbin/wifi makes the following ubus calls,
ubus call network reload
ubus call network.wireless down
ubus call network.wireless up
The first and third ubus calls both call drv_mac80211_setup,
while the second ubus call triggers wireless_device_setup_cancel.
So the call sequence becomes,
drv_mac80211_setup
wireless_device_setup_cancel
drv_mac80211_setup
In contrast, when LuCI is used to turn on wifi only a single call
is made to drv_mac80211_setup.
