Hi Marc, Oliver, and linux-can community, we are reaching out to you because we would like to advance the testing of the kernel CAN subsystem. We, that's Davide, Filippo and I, are volunteering to provide the patches for this, but would like to get your feedback and opinions first. We know about the can-tests repository[1] and think this is a good starting point for our efforts. Currently, there are two main activities we'd like to do: - Promote the test cases in can-tests to become part of the kernel selftests: This would mainly get the tests closer to the upstream kernel development, both in terms of maintenance and actually running them. CI systems like LKFT and CKI could easily be continuously running the tests. The downside is that existing automation depending on can-tests (which we don't know about) would need to be modified. - Extend the coverage of the tests: This could include testing for, e.g., vcan, vxcan, and the cangw netlink interface. But we're open to feedback here if you see any pressing areas. Like I stated in the beginning, this message should get the discussion started and we are looking forward to your feedback or concerns on these ideas. Thanks, Felix [1]: https://github.com/linux-can/can-tests
