2021-10-01libbpf: Fix memory leak in strsetAndrii Nakryiko1-0/+1
Free struct strset itself, not just its internal parts. Fixes: 90d76d3ececc ("libbpf: Extract internal set-of-strings datastructure APIs") Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Martin KaFai Lau <kafai@fb.com> Link: https://lore.kernel.org/bpf/20211001185910.86492-1-andrii@kernel.org
2021-03-19libbpf: Extract internal set-of-strings datastructure APIsAndrii Nakryiko1-0/+176
Extract BTF logic for maintaining a set of strings data structure, used for BTF strings section construction in writable mode, into separate re-usable API. This data structure is going to be used by bpf_linker to maintains ELF STRTAB section, which has the same layout as BTF strings section.
