It focuses for now on test_xdp_veth.sh, a small test which is not integrated yet in test_progs. The series is mostly about a rewrite of test_xdp_veth.sh to make it able to run under test_progs, relying on libbpf to manipulate bpf programs involved in the test. Signed-off-by: Alexis Lothoré --- Changes in v4: - add missing netns_close in an error path during programs attach - Link to v3: https://lore.kernel.org/r/20240716-convert_test_xdp_veth-v3-0-7b01389e3cb3@bootlin.com Changes in v3: - Fix doc style in the new test - Collect acked-by tags - Link to v2: https://lore.kernel.org/r/20240715-convert_test_xdp_veth-v2-0-46290b82f6d2@bootlin.com Changes in v2: - fix many formatting issues raised by checkpatch - use static namespaces instead of random ones - use SYS_NOFAIL instead of snprintf() + system () - squashed the new test addition patch and the old test removal patch - Link to v1: https://lore.kernel.org/r/20240711-convert_test_xdp_veth-v1-0-868accb0a727@bootlin.com --- Alexis Lothoré (eBPF Foundation) (2): selftests/bpf: update xdp_redirect_map prog sections for libbpf selftests/bpf: integrate test_xdp_veth into test_progs tools/testing/selftests/bpf/Makefile | 1 - .../selftests/bpf/prog_tests/test_xdp_veth.c | 213 +++++++++++++++++++++ .../testing/selftests/bpf/progs/xdp_redirect_map.c | 6 +- tools/testing/selftests/bpf/test_xdp_veth.sh | 121 ------------ 4 files changed, 216 insertions(+), 125 deletions(-) --- base-commit: 4837cbaa1365cdb213b58577197c5b10f6e2aa81 change-id: 20240710-convert_test_xdp_veth-04cc05f5557d Best regards,
