/*
* General overview:
* full generic netlink message:
* |nlmsghdr|genlmsghdr|<payload>
*
* payload:
* |optional fixed size family header|<sequence of netlink attributes>
*
* sequence of netlink attributes:
* I chose to have all "top level" attributes NLA_NESTED,
* corresponding to some real struct.
* So we have a sequence of |tla, len|<nested nla sequence>
*
* nested nla sequence:
* may be empty, or contain a sequence of netlink attributes
* representing the struct fields.
*
* The tag number of any field (regardless of containing struct)
* will be available as T_ ## field_name,
* so you cannot have the same field name in two differnt structs.
*
* The tag numbers themselves are per struct, though,
* so should always begin at 1 (not 0, that is the special "NLA_UNSPEC" type,
* which we won't use here).
* The tag numbers are used as index in the respective nla_policy array.
*
* GENL_struct(tag_name, tag_number, struct name, struct fields) - struct and policy
* genl_magic_struct.h
* generates the struct declaration,
* generates an entry in the tla enum,
* genl_magic_func.h
* generates an entry in the static tla policy
* with .type = NLA_NESTED
* generates the static <struct_name>_nl_policy definition,
* and static conversion functions
*
* genl_magic_func.h
*
* GENL_mc_group(group)
* genl_magic_struct.h
* does nothing
* genl_magic_func.h
* defines and registers the mcast group,
* and provides a send helper
*
* GENL_notification(op_name, op_num, mcast_group, tla list)
* These are notifications to userspace.
*
* genl_magic_struct.h
* generates an entry in the genl_ops enum,
* genl_magic_func.h
* does nothing
*
* mcast group: the name of the mcast group this notification should be
* expected on
* tla list: the list of expected top level attributes,
* for documentation and sanity checking.
*
* GENL_op(op_name, op_num, flags and handler, tla list) - "genl operations"
* These are requests from userspace.
*
* _op and _notification share the same "number space",
* op_nr will be assigned to "genlmsghdr->cmd"
*
* genl_magic_struct.h
* generates an entry in the genl_ops enum,
* genl_magic_func.h
* generates an entry in the static genl_ops array,
* and static register/unregister functions to
* genl_register_family_with_ops().
*
* flags and handler:
* GENL_op_init( .doit = x, .dumpit = y, .flags = something)
* GENL_doit(x) => .dumpit = NULL, .flags = GENL_ADMIN_PERM
* tla list: the list of expected top level attributes,
* for documentation and sanity checking.

drbd: Make drbd's use of netlink attribute flags less confusing Make it more clear in the flag names which flags are internal to drbd, and which are not. The check for mandatory attributes is the only extension visible at the netlink layer. Attributes with this flag set would look like unknown attributes to some kernel versions. The netlink layer would ignore them and also skip consistency checks on the attribute type and legth. To avoid this, we check for mandatory attributes first, remove the mandatory flag, and then process the attributes normally.

drbd: distribute former syncer_conf settings to disk, connection, and resource level This commit breaks the API again. Move per-volume former syncer options into disk_conf. Move per-connection former syncer options into net_conf. Renamed the remainign sync_conf to res_opts Syncer settings have been changeable at runtime, so we need to prepare for these settings to be runtime-changeable in their new home as well. Introduce new configuration operations, and share the netlink attribute between "attach" (create new disk) and "disk-opts" (change options). Same for "connect" and "net-opts". Some fields cannot be changed at runtime, however. Introduce a new flag GENLA_F_INVARIANT to be able to trigger on that in the generated validation and assignment functions.

Move per-connection former syncer options into net_conf. Renamed the remainign sync_conf to res_opts Syncer settings have been changeable at runtime, so we need to prepare for these settings to be runtime-changeable in their new home as well. Introduce new configuration operations, and share the netlink attribute between "attach" (create new disk) and "disk-opts" (change options). Same for "connect" and "net-opts". Some fields cannot be changed at runtime, however. Introduce a new flag GENLA_F_INVARIANT to be able to trigger on that in the generated validation and assignment functions.

drbd: distribute former syncer_conf settings to disk, connection, and resource level This commit breaks the API again. Move per-volume former syncer options into disk_conf. Move per-connection former syncer options into net_conf. Renamed the remainign sync_conf to res_opts Syncer settings have been changeable at runtime, so we need to prepare for these settings to be runtime-changeable in their new home as well. Introduce new configuration operations, and share the netlink attribute between "attach" (create new disk) and "disk-opts" (change options). Same for "connect" and "net-opts". Some fields cannot be changed at runtime, however. Introduce a new flag GENLA_F_INVARIANT to be able to trigger on that in the generated validation and assignment functions.
