Yes. I would like to avoid malloc() in can-utils where possible. From my understanding we provide software for embedded systems - and therefore malloc() should be avoided. My preferred idea...

The work around is a horrible way in terms of coding style. I googled around on this topic and found this: https://stackoverflow.com/questions/1867065/how-to-suppress-gcc-warnings-from-library-headers/1900578#1900578 I think we should go for such an...

I tried the original code from https://github.com/linux-can/can-doc/issues/2#issue-1709494008 and only changed `can0` to `vcan0` . That resulted in a working setup. But `candump any -td` shows that the gap between the...

Can you please check is it works with a virtual CAN interface in your setup (as I showed above) and check if the CAN traffic is analogue to my candump...

Can you please post the output of `lsmod | grep can` and `ip -d -s link show vcan0`?

`lsmod`looks good. But there are no RX/TX packets on the vcan0 interface. When I run your program on `vcan0`instead of `can0` it looks like this: ``` $ ip -d -s...

But if this would have been started, why are there no RX/TX packets for vcan0 visible?
