Rewrite to skel and ASSERT macros as well while we are at it. v3: - replace -f with -A to make it work with busybox ping. -A is available on both busybox and iputils, from the man page: On networks with low RTT this mode is essentially equivalent to flood mode. v2: - don't check result of bpf_map__fd (Yonghong Song) - remove from .gitignore (Andrii Nakryiko) - move ping_command into network_helpers (Andrii Nakryiko) - remove assert() (Andrii Nakryiko) Signed-off-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/bpf/20210804205524.3748709-1-sdf@google.com
