HI Everyone,
I have posted this question many times hoping to get some answer. It would be
appreciated if someone can help me with that .
I am wonder also if I can open a ticket for it on Openwrt wiki and what is the
procedure for it?
Here is my question :
I have an issue using ubus /netifd .
I can see some incident that it looks like there is a race condition somewhere
in ubus/netifd .
I can reproduce the problem as described below:
In a good scenario :
I add some lines in /etc/config/network to bring up a pptp tunnel.
I run >>/etc/init.d/network reload --I can see the interface got created.
At the same time I am listening to ubus event by running: >>ubus listen
On the creation I can see the following message from ubus:
{ "ubus.object.add": { "id": -788079186, "path": "network.interface.2" } }
{ "network.interface": { "action": "ifup", "interface": "2" } }
I then remove the lines from /etc/config/network and
>>/etc/init.d/network reload
I can see the interface is gone and I can see the messages from the ubus:
{ "network.interface": { "action": "ifdown", "interface": "2" } }
{ "ubus.object.remove": { "id": -788079186, "path": "network.interface.2" } }
In a bad scenario(after couple of tries):
I add some lines in /etc/network to bringup a pptp tunnel
then >> /etc/init.d/network reload
This time I only see :
{ "ubus.object.add": { "id": 680699142, "path": "network.interface.2" } }
As you can see there is no "ifup" at this time. From this moment ubus never
receive any notification.
I can see the interface got created but there is no way to remove it.
Top shows netifd consumes 99% cpu time.
/etc/init.d/network reload will return with timeout error.
The only way to get out of this state is reboot.
I appreciate if someone can give some help on this issue.
Thanks in advance,
Farid
