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