The tools/testing/selftests/bpf directory in the kernel source tree contains the test_bpftool_build.sh script that ensures that the various supported ways of building bpftool work correctly. This test isn't currently part of the tests automatically executed in CI. Add a dedicated job in test.yml to execute this script and validate that bpftool can be built correctly. As the test has very little dependencies (only a build test, no dependency on built artifact), the added workflow remains simple and isolated from the other "build-and-tests" workflows: - attached to highest parent workflow (test.yml) - it only tests host build, so no need to run it as many time as the matrix script generates configurations - supports download_sources flag, so can be run from kernel tree or vmtest tree Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore@bootlin.com>
