Support updating bpf links

Open insearchoflosttime opened this issue 3 years ago • 0 comments

To update a link in libbpf, there is this API:

LIBBPF_API int bpf_link_update(int link_fd, int new_prog_fd,
			       const struct bpf_link_update_opts *opts);

https://github.com/libbpf/libbpf/blob/3591deb9bc6b0848721f831790b78ae0a593b4c5/src/bpf.h#L434

In libbpf-rs, we should support this operation as well
