Martin KaFai Lau c9f1155645 libbpf: Ensure undefined bpf_attr field stays 0 ... The commit 9e926acda0 ("libbpf: Find correct module BTFs for struct_ops maps and progs.") sets a newly added field (value_type_btf_obj_fd) to -1 in libbpf when the caller of the libbpf's bpf_map_create did not define this field by passing a NULL "opts" or passing in a "opts" that does not cover this new field. OPT_HAS(opts, field) is used to decide if the field is defined or not: ((opts) && opts->sz >= offsetofend(typeof(*(opts)), field)) Once OPTS_HAS decided the field is not defined, that field should be set to 0. For this particular new field (value_type_btf_obj_fd), its corresponding map_flags "BPF_F_VTYPE_BTF_OBJ_FD" is not set. Thus, the kernel does not treat it as an fd field.
