Yonghong Song 2220ecf55c selftests/bpf: Skip btf_tag test if btf_tag attribute not supported ... Commit c240ba2878 ("selftests/bpf: Add a test with a bpf program with btf_tag attributes") added btf_tag selftest to test BTF_KIND_TAG generation from C source code, and to test kernel validation of generated BTF types. But if an old clang (clang 13 or earlier) is used, the following compiler warning may be seen: progs/tag.c:23:20: warning: unknown attribute 'btf_tag' ignored and the test itself is marked OK. The compiler warning is bad and the test itself shouldn't be marked OK. This patch added the check for btf_tag attribute support. If btf_tag is not supported by the clang, the attribute will not be used in the code and the test will be marked as skipped. For example, with clang 13: ./test_progs -t btf_tag #21 btf_tag:SKIP Summary: 1/0 PASSED, 1 SKIPPED, 0 FAILED The selftests/README.rst is updated to clarify when the btf_tag test may be skipped.
