tipc: rename struct port_list to struct tipc_port_list

2011-12-30T02:53:29Z

Make this rename so that it is consistent with the majority of the other tipc structs and to assist in removing any ambiguity with other similar names in other subsystems. Signed-off-by: Paul Gortmaker

tipc: Optimize creation of connection protocol messages

2011-06-24T20:18:18Z

Simplifies the creation of connection protocol messages by eliminating the passing of information that is no longer required, is constant, or is contained within the port structure that is issuing the message. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Don't create payload message using connection protocol routine

2011-06-24T20:18:18Z

Modifies the logic that creates a connection termination payload message so that it no longer (mis)uses a routine that creates a connection protocol message. The revised code is now more easily understood, and avoids setting several fields that are either not present in payload messages or were being set more than once.

tipc: Reject connection protocol message sent to unconnected port

2011-06-24T20:18:18Z

Restructures the logic used in tipc_port_recv_proto_msg() to ensure that incoming connection protocol messages are handled properly. The routine now uses a two-stage process that first ensures the message applies on an existing connection and then processes the request. This corrects a loophole that allowed a connection probe request to be processed if it was sent to an unconnected port that had no names bound to it.

tipc: Optimize creation of FIN messages

2011-06-24T20:18:18Z

Speeds up the creation of the FIN message that terminates a TIPC connection. The typical peer termination message is now created by duplicating the terminating port's standard payload message header and adjusting the message size, importance, and error code fields, rather than building all fields of the message from scratch. A FIN message that is directed to the port itself is created the same way. but also requires swapping the origin and destination address fields. In addition to reducing the work required to create FIN messages, these changes eliminate several instances of duplicated code, Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Cleanup of message header size terminology

2011-06-24T20:18:17Z

Performs cosmetic cleanup of the symbolic names used to specify TIPC payload message header sizes. The revised names now more accurately reflect the payload messages in which they can appear. In addition, several places where these payload message symbol names were being used to create non-payload messages have been updated to use the proper internal message symbolic name. No functional changes are introduced by this rework. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Optimizations & corrections to message rejection

2011-06-24T20:18:15Z

Optimizes the creation of a returned payload message by duplicating the original message and then updating the small number of fields that need to be adjusted, rather than building the new message header from scratch. In addition, certain operations that are not always required are relocated so that they are only done if needed. These optimizations also have the effect of addressing other issues that were present previously: 1) Fixes a bug that caused the socket send routines to return the size of the returned message, rather than the size of the sent message, when a returnable payload message was sent to a non-existent destination port. 2) The message header of the returned message now matches that of the original message more closely. The header is now always the same size as the original header, and some message header fields that weren't being initialized in the returned message header are now populated correctly -- namely the "d" and "s" bits, and the upper bound of a multicast name instance (where present).

tipc: Optimize routing of returned payload messages

2011-06-24T20:18:15Z

Reduces the work involved in transmitting a returned payload message by doing only the work necessary to route such a message directly to the specified destination port, rather than invoking the code used to route an arbitrary message to an arbitrary destination.

tipc: Add sanity check to detect rejection of non-payload messages

2011-06-24T20:18:15Z

Introduces an internal sanity check to ensure that the only undeliverable messages TIPC attempts to return to their origin are application payload messages. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Standardize exit logic for message rejection handling

2011-06-24T20:18:15Z

Modifies the routine that handles the rejection of payload messages so that it has a single exit point that frees up the rejected message, thereby eliminating some duplicated code. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker
