** Description changed: - You should be able to build all the tests inside a subtest directory in tools/testing/selftests from a kernel tree with command: - make TARGETS=net + [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 - But with our 4.15 kernel these binary files in the net directory cannot be built correctly: - * reuseport_bpf - * reuseport_bpf_cpu - * reuseport_dualstack - * reuseaddr_conflict - * reuseport_bpf_numa + For example, the following tests in net directory won't be built: + * reuseport_bpf + * reuseport_bpf_cpu + * reuseport_dualstack + * reuseaddr_conflict + * reuseport_bpf_numa - You can only build them with: - make TARGETS=net run_tests + They can be build with: + make TARGETS=net run_tests - This will also trigger the test, which is not ideal for the granularity - improvement. + However, this will also start all of the tests in this subset, which is + not ideal for the granularity improvement. + + [Fix] + * 14f1889f selftests: Fix loss of test output in run_kselftests.sh + * 44f01352 selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP headers + * 8ce72dc3 selftests: fix headers_install circular dependency + + These patches can be cherry-picked for Bionic.
