There are 2 "main" parts in test_flow_dissector.sh: - a set of tests checking flow_dissector programs attachment to either root namespace or non-root namespace - dissection test The first set is integrated in flow_dissector.c, which already contains some existing tests for flow_dissector programs. This series uses the opportunity to update a bit this file (use new assert, re-split tests, etc) The second part is migrated into a new file under test_progs, flow_dissector_classification.c. It uses the same eBPF programs as flow_dissector.c, but the difference is rather about how those program are executed: - flow_dissector.c manually runs programs with BPF_PROG_RUN - flow_dissector_classification.c sends real packets to be dissected, and so it also executes kernel code related to eBPF flow dissector (eg: __skb_flow_bpf_to_target) --- Alexis Lothoré (eBPF Foundation) (10): selftests/bpf: add a macro to compare raw memory selftests/bpf: use ASSERT_MEMEQ to compare bpf flow keys selftests/bpf: replace CHECK calls with ASSERT macros in flow_dissector test selftests/bpf: re-split main function into dedicated tests selftests/bpf: expose all subtests from flow_dissector selftests/bpf: add gre packets testing to flow_dissector selftests/bpf: migrate flow_dissector namespace exclusivity test selftests/bpf: Enable generic tc actions in selftests config selftests/bpf: migrate bpf flow dissectors tests to test_progs selftests/bpf: remove test_flow_dissector.sh tools/testing/selftests/bpf/.gitignore | 1 - tools/testing/selftests/bpf/Makefile | 3 +- tools/testing/selftests/bpf/config | 1 + .../selftests/bpf/prog_tests/flow_dissector.c | 307 ++++++-- .../bpf/prog_tests/flow_dissector_classification.c | 851 +++++++++++++++++++++ tools/testing/selftests/bpf/test_flow_dissector.c | 780 ------------------- tools/testing/selftests/bpf/test_flow_dissector.sh | 178 ----- tools/testing/selftests/bpf/test_progs.h | 25 + 8 files changed, 1107 insertions(+), 1039 deletions(-) --- base-commit: 16e1d1c377aa4c56223701a31f3bfa88505e7e4f change-id: 20241019-flow_dissector-3eb0c07fc163 Best regards,
