selftests/bpf: Test parsing of (multi-)split BTF

2025-11-04T21:44:12Z

Write raw BTF to files, parse it and compare to original; this allows us to test parsing of (multi-)split BTF code. Signed-off-by: Alan Maguire Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20251104203309.318429-3-alan.maguire@oracle.com

selftests/bpf: Test multi-split BTF

2025-05-20T23:22:30Z

Extend split BTF test to cover case where we create split BTF on top of existing split BTF and add info to it; ensure that such BTF can be created and handled by searching within it, dumping/comparing to expected.

selftests/bpf: Switch to new btf__type_cnt/btf__raw_data APIs

2021-10-22T23:09:14Z

Replace the calls to btf__get_nr_types/btf__get_raw_data in selftests with new APIs btf__type_cnt/btf__raw_data. The old APIs will be deprecated in libbpf v0.7+.
