> bpftool: Reject non-autoload programs for light skeletons
>
> When generating a light skeleton (bpftool gen skeleton -L), there is no
> libbpf runtime object or bpf_program__set_autoload() API available to
> enable/disable the autoloading of programs. If a BPF program in the
> object has autoload disabled (e.g. via SEC("?...")), bpf_object__load()
> silently skips loading it. bpftool still generates struct bpf_prog_desc
> fields and attach functions in the light skeleton header, leaving
> skel->progs.<name>.prog_fd uninitialized (0).
>
> Explicitly reject non-autoloaded programs when use_loader is true with
> an error message, preventing the generation of broken light skeleton
> headers.

This looks like a bug fix for light skeleton generation. Should this
include a Fixes: tag?
Fixes: d510296d331a ("bpftool: Use syscall/loader program in \"prog load\"
and \"gen skeleton\" command.")
