Hi,

CAN_ERR_CNT was not introduced until Linux 6.0, even though the proprietary driver has supported the socket-CAN interface for much longer. Nevertheless, we plan to include support for it in the next version. Thank you for your contribution.

Regarding your comment that the error counters may ...

Hi,

The new peak_usb driver is ready and operational. But at the moment, I can't say if it will be pushed in a near future.

Hi,

set when the frame was sent via the socket it is received on. This flag can be interpreted as a ‘transmission confirmation’ when the CAN driver supports the echo of frames on driver level,
As said, MSG_CONFIRM means that the frame as been echoed on driver level.

To be more precise: SocketCAN ...

Hi,

it's that your netdev driver variant simply doesn't implement that part of the API for hardware loopback frames, correct?
Correct. However, MSG_CONFIRM is not a SocketCAN-specific feature; it is part of the generic socket API.

If so, is this something you'd consider adding in a future ...

Hi,

Thank you for this very detailed report. We have never observed this kind of behavior, and, as far as we can tell, nothing in the PCAN driver for Linux is designed to reset these timestamps to 0 under any circumstances.

We will therefore set up a test environment to first try to reproduce this ...

Hi,

The ECHO feature is not supported by the netdev variant of the PCAN driver for Linux, which is why the ECHO flag is cleared from the exposed network interface. Therefore, you will never see MSG_CONFIRM in the CAN frames read from these channels.

Regarding “loopback” frames (i.e., those ...

Hi,

Yes, the proprietary PCAN driver for Linux currently supports more features than the one included in the kernel.

We plan to take advantage of the addition of CAN-XL support to address these limitations.

However, if you’d rather not wait, we also offer an out-of-tree version of this driver ...

Hello,

Yes, you're right: in order to fix that issue, you should download the pre release of the next version of PCAN from: https://cavok.peak-system.com/X9EkN5L.

Hello,

First, I don't like this:
EXTRA_CFLAGS="... -DNO_DEBUG -DMODVERSIONSO_DONGLE_SUPPORT -DNO_PCCARD_SUPPORT...
Is this a copy-paste issue or the real command line? Fyi, this should be instead:
EXTRA_CFLAGS="... -DNO_DEBUG -DMODVERSIONS -DNO_PARPORT_SUBSYSTEM -DUSB_SUPPORT -DPCI_SUPPORT ...
