Hi Developers,
A quick question - how does ubus know a network connection is actually up?
I have a tunnel interface, which is available at boot time (so always
available basically) and then a userland daemon that manages it - assigns
IP address to the interface, authentication, etc
I¹ve written a /lib/netifd/proto/mytun.sh file, with
proto_mytun_init_config() {
# Have tried without these, doesn’t seem to make a difference
available=1
no_device=0
}
proto_mytun_setup() {
local config="$1"
local iface="$2"
/etc/init.d/mytun start
# Attempt to tell everyone it¹s up - doesn¹t seem to work
uci_toggle_state network "$1" up 1
uci_toggle_state network "$1" connect_time $(sed -ne 's![^0-9].*$!!p'
/proc/uptime)
}
proto_mytun_teardown() {
local interface="$1"
/etc/init.d/mytun stop
proto_kill_command "$interface"
}
add_proto mytun
With the above, LuCI seems to know the state (shows up/down correctly in
the GUI) and ifup/ifdown seem to work consistently, but ubus does not think
it is up, and the Online for: counter never changes:
root@OpenWRT:~# ubus call network.interface.mytun status
{
"up": false,
"pending": false,
"available": true,
"autostart": false,
"proto": "mytun",
"device": "mytdev",
"data": {
}
}
root@OpenWRT:~# ifup mytun
root@OpenWRT:~# ubus call network.interface.mytun status
{
"up": false,
"pending": true,
"available": true,
"autostart": true,
"proto": "mytun",
"device": "miydev",
"data": {
}
}
devstatus on mytun returns as expected:
{
"external": true,
"present": true,
"type": "Network device",
"up": true,
"link": true,
"mtu": 1340,
"macaddr": "0:0:0:0:0:0",
"txqueuelen": 0,
"statistics": {
// trimmed for length
}
}
Can someone point me in the right direction?
Thanks,
Ken
