/*
 * Minimal, map-less program. Driven through libbpf's gen_loader (gen_hash)
 * by prog_tests/signed_loader.c so the generated light-skeleton loader (with
 * the emit_signature_match metadata check) can be exercised against good
 * and tampered metadata. A socket filter needs no load-time attach resolution,
 * and having no maps keeps the generated loader's ctx trivial (0 maps, 1 prog).
