Hi all, This patch series continues the work to migrate the *.sh tests into prog_tests framework. test_xdp_redirect_multi.sh tests the XDP redirections done through bpf_redirect_map(). This is already partly covered by test_xdp_veth.c that already tests map redirections at XDP level. What isn't covered yet by test_xdp_veth is the use of the broadcast flags (BPF_F_BROADCAST or BPF_F_EXCLUDE_INGRESS) and XDP egress programs. Hence, this patch series add test cases to test_xdp_veth.c to get rid of the test_xdp_redirect_multi.sh: - PATCH 1 Add an helper to generate unique names - PATCH 2 to 9 rework test_xdp_veth to make it more generic and allow to configure different test cases - PATCH 10 adds test cases for 'classic' bpf_redirect_map() - PATCH 11 and 12 cover the broadcast flags - PATCH 13 covers the XDP egress programs - PATCH 14 removes test_xdp_redirect_multi.sh Signed-off-by: Bastien Curutchet (eBPF Foundation) <bastien.curutchet@xxxxxxxxxxx> --- Changes in v3: - Add append_tid() helper and use unique names to allow parallel testing - Check create_network()'s return value through ASSERT_OK() - Remove check_ping() and unused defines - Change next_veth type (from string to int) - Link to v2: https://lore.kernel.org/r/20250121-redirect-multi-v2-0-fc9cacabc6b2@xxxxxxxxxxx Changes in v2: - Use serial_test_* to avoid conflict between tests - Link to v1: https://lore.kernel.org/r/20250121-redirect-multi-v1-0-b215e35ff505@xxxxxxxxxxx --- Bastien Curutchet (eBPF Foundation) (14): selftests/bpf: helpers: Add append_tid() selftests/bpf: test_xdp_veth: Remove unused defines selftests/bpf: test_xdp_veth: Remove unecessarry check_ping() selftests/bpf: test_xdp_veth: Use int to describe next veth selftests/bpf: test_xdp_veth: Split network configuration selftests/bpf: test_xdp_veth: Rename config[] selftests/bpf: test_xdp_veth: Add prog_config[] table selftests/bpf: test_xdp_veth: Add XDP flags to prog_configuration selftests/bpf: test_xdp_veth: Use unique names selftests/bpf: test_xdp_veth: Add new test cases for XDP flags selftests/bpf: Optionally select broadcasting flags selftests/bpf: test_xdp_veth: Add XDP broadcast redirection tests selftests/bpf: test_xdp_veth: Add XDP program on egress test selftests/bpf: Remove test_xdp_redirect_multi.sh tools/testing/selftests/bpf/Makefile | 2 - tools/testing/selftests/bpf/network_helpers.c | 11 + tools/testing/selftests/bpf/network_helpers.h | 10 + .../selftests/bpf/prog_tests/test_xdp_veth.c | 589 ++++++++++++++++----- .../testing/selftests/bpf/progs/xdp_redirect_map.c | 89 ++++ .../selftests/bpf/progs/xdp_redirect_multi_kern.c | 41 +- .../selftests/bpf/test_xdp_redirect_multi.sh | 214 -------- tools/testing/selftests/bpf/xdp_redirect_multi.c | 226 -------- 8 files changed, 608 insertions(+), 574 deletions(-) --- base-commit: e65d1a6e096af0648ffdbc9d7e8bd7a44dcc700b change-id: 20250103-redirect-multi-245d6eafb5d1 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet@xxxxxxxxxxx>
