   2  * General overview:
   3  * full generic netlink message:
   4  * |nlmsghdr|genlmsghdr|<payload>
   5  *
   6  * payload:
   7  * |optional fixed size family header|<sequence of netlink attributes>
   8  *
   9  * sequence of netlink attributes:
  10  * I chose to have all "top level" attributes NLA_NESTED,
  11  * corresponding to some real struct.
  12  * So we have a sequence of |tla, len|<nested nla sequence>
  13  *
  14  * nested nla sequence:
  15  * may be empty, or contain a sequence of netlink attributes
  16  * representing the struct fields.
  17  *
  18  * The tag number of any field (regardless of containing struct)
  19  * will be available as T_ ## field_name,
  20  * so you cannot have the same field name in two differnt structs.
  21  *
  22  * The tag numbers themselves are per struct, though,
  23  * so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
  24  * which we won't use here).
  25  * The tag numbers are used as index in the respective nla_policy array.
  26  *
  27  * GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
  28  *      genl_magic_struct.h
  29  *              generates the struct declaration,
  30  *              generates an entry in the tla enum,
  31  *      genl_magic_func.h
  32  *              generates an entry in the static tla policy
  33  *              with .type = NLA_NESTED
  34  *              generates the static <struct_name>_nl_policy definition,
  35  *              and static conversion functions
  36  *
  37  *      genl_magic_func.h
  38  *
  39  * GENL_mc_group(group)
  40  *      genl_magic_struct.h
  41  *              does nothing
  42  *      genl_magic_func.h
  43  *              defines and registers the mcast group,
  44  *              and provides a send helper
  45  *
  46  * GENL_notification(op_name, op_num, mcast_group, tla list)
  47  *      These are notifications to userspace.
  48  *
  49  *      genl_magic_struct.h
  50  *              generates an entry in the genl_ops enum,
  51  *      genl_magic_func.h
  52  *              does nothing
  53  *
  54  *      mcast group: the name of the mcast group this notification should be
  55  *      expected on
  56  *      tla list: the list of expected top level attributes,
  57  *      for documentation and sanity checking.
  58  *
  59  * GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
  60  *      These are requests from userspace.
  61  *
  62  *      _op and _notification share the same "number space",
  63  *      op_nr will be assigned to "genlmsghdr->cmd"
  64  *
  65  *      genl_magic_struct.h
  66  *              generates an entry in the genl_ops enum,
  67  *      genl_magic_func.h
  68  *              generates an entry in the static genl_ops array,
  69  *              and static register/unregister functions to
  70  *              genl_register_family().
  71  *
  72  *      flags and handler:
  73  *              GENL_op_init( .doit = x, .dumpit = y, .flags = something)
  74  *              GENL_doit(x) => .dumpit = NULL, .flags = GENL_ADMIN_PERM
  75  *      tla list: the list of expected top level attributes,
