Subject: Re: [PATCH iproute2] ss: Use rtnl_dump_filter in handle_netlink_request

I established some simple OpenVPN connection (at least by the logs and
ss I see that peer is connected), but
I dont get any errors with ss.

So can you please provide some more info how did you tested this patch
? I am surprised that this is caused only
by these changes ...
