Merge branch 'bpf-samples-improvements'

Jakub Kicinski says: ==================== This set is next part of a quest to get rid of the bpf_load ELF loader. It fixes some minor issues with the samples and starts the conversion. First patch fixes ping invocations, ping localhost defaults to IPv6 on modern setups. Next load_sock_ops sample is removed and users are directed towards using bpftool directly. Patch 4 removes the use of bpf_load from samples which don't need the auto-attachment functionality at all. Patch 5 improves symbol counting in libbpf, it's not currently an issue but it will be when anyone adds a symbol with a long name. Let's make sure that person doesn't have to spend time scratching their head and wondering why .a and .so symbol counts don't match. v2: - specify prog_type where possible (Andrii). ==================== Acked-by: Song Liu <songliubraving@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
