This is enforced by\ncheck_map_prog_compatibility() when the map is referenced from a\nprogram such as signed BPF loaders.\n\nA bpf_map_elem iterator, however, binds its target map at attach\ntime in bpf_iter_attach_map() instead of referencing it from the\nprogram, so the exclusivity check is never reached. On top of that,\nthe iterator exposes the map value as a writable buffer."
