mac80211: fix no_reload logic (FS#3902)
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.
