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_with_ops().
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,
76 * for documentation and sanity checking.
