I'm trying to add additional option in hostapd config file, but if i add them in /etc/config/wireless as
option key 'value'
some of my custom config are not present in /var/run/hostapd-phy0.conf (i think uci is missing some hostapd flag and so they are not added in genersted hostapd config file)

Is there a way to add custom flags in /etc/config/wireless (like option 'extra' 'value')?
Or at least pass a custom config file to hostapd instead of the uci generated one?

The script /lib/netifd/hostapd.sh generates hostapd.conf.  You would need to extend that script to parse your new parameter.  hostapd.sh is distributed in the hostapd-common package.

I think you can modify hostapd.conf then send a signal 1 to hostapd to make it load the new configuration, but that would be more suitable for testing than production.

Hi,

I'm also trying to include a new option to /etc/config/wireless so it is finally present in /var/run/hostapd-phy0.conf. I have been travelling through the code and this is what I have seen:

- Netifd is is charge of listening network events and manage network interfaces upon these events.
- When netifd starts, it registers some scripts as handlers. The handler that is called when an event related to a wifi network interface rises is /lib/netifd/mac80211.sh.
- /lib/netifd/mac80211.sh uses functions from /lib/netifd/hostapd.sh and /lib/netifd/netifd-wireless.sh to generate the hostapd config file.
- When netifd  calls to /lib/netifd/mac80211.sh, it passes a json config as an argument. I think that hostapd config is derived from this json config, however I can't see the new options I add to /etc/config/wireless in this json config.

Please, could anyone explain how all these scripts interact among them and with netfid? Who is in charge of parsing the /etc/config/wireless file? How the json config that is passed to /lib/netifd/mac80211.sh as an argument is derived?

Thanks in advance for your help.
