From 60fb4c92b6b0d1582d31e02167b90b424185f3a2 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 30 Oct 2019 16:57:22 +0100 Subject: hostapd: add ubus reload Add ubus interface to hostapd and wpa_supplicant to allow dynamically reloading wiface configuration without having to restart the hostapd process. As a consequence, both hostapd and wpa_supplicant are now started persistently on boot for each wifi device in the system and then receive ubus calls adding, modifying or removing interface configuration. At a later stage it would be desirable to reduce the services to one single instance managing all radios.
