--- Comment #1 from Paul Floyd <pjfl...@wanadoo.fr> ---
In bpf_obj_get_info_size we only handle

   if (VG_(strstr)(buf, "prog_type:"))
      return sizeof(struct vki_bpf_prog_info);

   if (VG_(strstr)(buf, "map_type:"))
      return sizeof(struct vki_bpf_map_info);

   return 0;

Looks like we are missing btf_info and link_info.
