| 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. | |
