YAML/Netlink gives us the ability to easily interface with Netlink in higher level laguages. In particular, there is a Python library already available in tree, under tools/net. Add the scaffolding which allows writing tests using this library. The "scaffolding" is needed because the library lives under tools/net and uses YAML files from under Documentation/. So we need a small amount of glue code to find those things and add them to TEST_FILES. This series adds both a basic SW sanity test and driver test which can be run against netdevsim or a real device. When I develop core code I usually test with netdevsim, then a real device, and then a backport to Meta's kernel. Because of the lack of integration, until now I had to throw away the (YNL-based) test script and netdevsim code. Running tests in tree directly: $ ./tools/testing/selftests/net/nl_netdev.py KTAP version 1 1..2 ok 1 nl_netdev.empty_check ok 2 nl_netdev.lo_check # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0 in tree via make: $ make -C tools/testing/selftests/ TARGETS=net \ TEST_PROGS=nl_netdev.py TEST_GEN_PROGS="" run_tests [ ... ] and installed externally, all seem to work: $ make -C tools/testing/selftests/ TARGETS=net \ install INSTALL_PATH=/tmp/ksft-net $ /tmp/ksft-net/run_kselftest.sh -t net:nl_netdev.py [ ... ] For driver tests I followed the lead of net/forwarding and get the device name from env and/or a config file. v3: - fix up netdevsim C - various small nits in other patches (see changelog in patches) v2: https://lore.kernel.org/all/20240403023426.1762996-1-kuba@kernel.org/ - don't add to TARGETS, create a deperate variable with deps - support and use with - support and use passing arguments to tests v1: https://lore.kernel.org/all/20240402010520.1209517-1-kuba@kernel.org/ ==================== Signed-off-by: David S.
