      "message": "[NET]: Add netlink connector.\n\nKernel connector - new userspace \u003c-\u003e kernel space easy to use\ncommunication module which implements easy to use bidirectional\nmessage bus using netlink as it\u0027s backend.  Connector was created to\neliminate complex skb handling both in send and receive message bus\ndirection.\n\nConnector driver adds possibility to connect various agents using as\none of it\u0027s backends netlink based network.  One must register\ncallback and identifier. When driver receives special netlink message\nwith appropriate identifier, appropriate callback will be called.\n\nFrom the userspace point of view it\u0027s quite straightforward:\n\n\tsocket();\n\tbind();\n\tsend();\n\trecv();\n\nBut if kernelspace want to use full power of such connections, driver\nwriter must create special sockets, must know about struct sk_buff\nhandling...  Connector allows any kernelspace agents to use netlink\nbased networking for inter-process communication in a significantly\neasier way:\n\nint cn_add_callback(struct cb_id *id, char *name, void (*callback) (void *));\nvoid cn_netlink_send(struct cn_msg *msg, u32 __groups, int gfp_mask);\n\nstruct cb_id\n{\n\t__u32\t\t\tidx;\n\t__u32\t\t\tval;\n};\n\nidx and val are unique identifiers which must be registered in\nconnector.h for in-kernel usage.  void (*callback) (void *) - is a\ncallback function which will be called when message with above idx.val\nwill be received by connector core.\n\nUsing connector completely hides low-level transport layer from it\u0027s\nusers.\n\nConnector uses new netlink ability to have many groups in one socket.\n\n[ Incorporating many cleanups and fixes by myself and\n  Andrew Morton -DaveM ]\n\nSigned-off-by: Evgeniy Polyakov \u003cjohnpol@2ka.mipt.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: David S.
