** Description changed: [Impact] - With 4.15 kernel, not all binary files inside a subtest directory in tools/testing/selftests of a kernel tree can be built with command: - make TARGETS=$subtest + With 4.15 kernel, not all binary files inside a subtest directory in + tools/testing/selftests of a kernel tree can be built with command: - For example, the following tests in net directory won't be built: - * reuseport_bpf - * reuseport_bpf_cpu - * reuseport_dualstack - * reuseaddr_conflict - * reuseport_bpf_numa + make TARGETS=$subtest - They can be build with: - make TARGETS=net run_tests + For example, the following binaries in net directory won't be built: + * reuseport_bpf + * reuseport_bpf_cpu + * reuseport_dualstack + * reuseaddr_conflict + * reuseport_bpf_numa - However, this will also start all of the tests in this subset, which is - not ideal for the granularity improvement. + They can only be build with: + + make TARGETS=net run_tests + + However, this will also start all of the tests in this subset and it's + is not ideal for the granularity improvement, in which we will want to + run tests one-by-one. [Fix] 1. 14f1889f selftests: Fix loss of test output in run_kselftests.sh 2. 44f01352 selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP headers 3. 8ce72dc3 selftests: fix headers_install circular dependency 4. 27d79a2b selftests: fix bpf build/test workflow regression when KBUILD_OUTPUT is set 5. e2e88325 selftests: vm: Fix test build failure when built by itself The 2nd needs to be backported with some context adjustment. - The 3rd and 4th patch would need to be applied with -C2, the other two can be cherry-picked for Bionic. + The 3rd and 4th patch would need to be applied with -C2, the other two + can be cherry-picked for Bionic. - The third patch (8ce72dc3) is the fix for this issue.

Please find attachment in the bug report for the test result. [Where problems could occur] - As this is just tested with generic Bionic 4.15 kernel on a bare-metal system, it's is possible to see other issues on different variants. If this change is incorrect it will cause issue to our automated-testing and regression-testing, but it won't affect the real kernel functionality. + As this is just tested with generic Bionic 4.15 kernel on a bare-metal + system, it's is possible to see other issues on different variants.
