Multiple files/programs in `tools/testing/selftests/bpf/prog_tests/` still heavily use the `CHECK` macro, even when better `ASSERT_` alternatives are available. As it was already pointed out by Yonghong Song [1] in the bpf selftests the use of the ASSERT_* series of macros is preferred over the CHECK macro. This patchset replaces the usage of `CHECK(` macros to the equivalent `ASSERT_` family of macros in the following prog_tests: - bind_perm.c - bpf_obj_id.c - bpf_tcp_ca.c - vmlinux.c [1] https://lore.kernel.org/lkml/0a142924-633c-44e6-9a92-2dc019656bf2@xxxxxxxxx Changes in v3: - Addressed the following points mentioned by Yonghong Song - Improved `bpf_map_lookup_elem` assertion in bpf_tcp_ca. - Replaced assertion introduced in v2 with one that checks `thread_ret` instead of `pthread_join`. This ensures that `server`'s return value (thread_ret) is the one being checked, as oposed to `pthread_join`'s return value, since the latter one is less likely to fail. Changes in v2: - Fixed pthread_join assertion that broke the previous test Previous version: v2 - https://lore.kernel.org/lkml/GV1PR10MB6563AECF8E94798A1E5B36A4E8B6A@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx v1 - https://lore.kernel.org/lkml/GV1PR10MB6563FCFF1C5DEBE84FEA985FE8B0A@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Yuran Pereira (4): Replaces the usage of CHECK calls for ASSERTs in bpf_tcp_ca Replaces the usage of CHECK calls for ASSERTs in bind_perm Replaces the usage of CHECK calls for ASSERTs in bpf_obj_id selftests/bpf: Replaces the usage of CHECK calls for ASSERTs in vmlinux .../selftests/bpf/prog_tests/bind_perm.c | 6 +- .../selftests/bpf/prog_tests/bpf_obj_id.c | 204 +++++++----------- .../selftests/bpf/prog_tests/bpf_tcp_ca.c | 48 ++--- .../selftests/bpf/prog_tests/vmlinux.c | 16 +- 4 files changed, 105 insertions(+), 169 deletions(-) -- 2.25.1
