From bfa83a9e03cf8d501c6272999843470afecb32ed Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Thu, 10 Nov 2005 02:25:51 +0100 Subject: [NETLINK]: Type-safe netlink messages/attributes interface Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation. The resulting netlink code should be smaller, less error prone and easier to understand. Signed-off-by: Thomas Graf Signed-off-by: David S.

It solves the problem of protocol numbers running out by introducing a so called controller taking care of id management and name resolving. Generic netlink modules register themself after filling out their id card (struct genl_family), after successful registration the modules are able to register callbacks to command numbers by filling out a struct genl_ops and calling genl_register_op(). The registered callbacks are invoked with attributes parsed making life of simple modules a lot easier. Although generic netlink modules can request static identifiers, it is recommended to use GENL_ID_GENERATE and to let the controller assign a unique identifier to the module. Userspace applications will then ask the controller and lookup the idenfier by the module name. Due to the current multicast implementation of netlink, the number of generic netlink modules is restricted to 1024 to avoid wasting memory for the per socket multiacst subscription bitmask.
