yonghong-song · yonghong-song · commit bf5b9a5bf409 · 2019-01-17T09:59:04.000-08:00
The kernel libbpf library https://github.com/torvalds/linux/tree/master/tools/lib/bpf provides common functionality for handling bpf programs, maps, ELF parsing, probing, BTF manipulation, etc. The library has been recommended to the community as a common library for bpf/btf handling. A separate repository https://github.com/libbpf/libbpf has been created for this purpose. This patch brings in libbpf to bcc. The following command is executed to crate a libbpf submodule at src/cc/libbpf: git submodule add https://github.com/libbpf/libbpf.git src/cc/libbpf Signed-off-by: Yonghong Song <yhs@fb.com>
