Now I have a different question, is it possible to bind different sockets with
different src.addr to one interface.

of course, yes.

Because it is saying 'bind failed: Device 
or resource busy' if I want to do this ('$ip addr add j1939 0x01 dev can0' is 
working, of course)

It should work. Since '$ ip addr add ...' worked, there must be something in the code.
I look in the code for this. Did I understand well that only the first bind() succeeds?

Or do I have to do this with recvmsg()? 

no, wrong idea.

Because as you know I want keep the various src address'.

I understand your goal...

Kind regards,
