tipc: Avoid recomputation of outgoing message length

2011-05-10T20:03:57Z

Rework TIPC's message sending routines to take advantage of the total amount of data value passed to it by the kernel socket infrastructure. This change eliminates the need for TIPC to compute the size of outgoing messages itself, as well as the check for an oversize message in tipc_msg_build(). In addition, this change warrants an explanation: - res = send_packet(NULL, sock, &my_msg, 0); + res = send_packet(NULL, sock, &my_msg, bytes_to_send); Previously, the final argument to send_packet() was ignored (since the amount of data being sent was recalculated by a lower-level routine) and we could just pass in a dummy value (0). Now that the recalculation is being eliminated, the argument value being passed to send_packet() is significant and we have to supply the actual amount of data we want to send.

tipc: Eliminate obsolete routine for handling routed messages

2011-03-13T20:35:19Z

Eliminates a routine that is used in handling messages arriving from another cluster or zone. Such messages can no longer be received by TIPC now that multi-cluster and multi-zone network support has been eliminated. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Eliminate remaining support for routing table messages

2011-03-13T20:35:19Z

Gets rid of all remaining code relating to ROUTE_DISTRIBUTOR messages. These messages were only used in multi-cluster and multi-zone networks, which TIPC no longer supports. (For safety, TIPC now treats such messages the same way that it handles other unrecognized messages.) Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Eliminate timestamp from link protocol messages

2011-03-13T20:35:17Z

Removes support for the timestamp field of TIPC's link protocol messages. This field was previously used to hold an OS-dependent timestamp value that was used to assist in debugging early versions of TIPC. The field has now been deemed unnecessary and has been removed from the latest TIPC specification. This change has no impact on the operation of TIPC since the field was set by TIPC, but never referenced. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Remove unused message header field for requested number of links

2011-02-23T23:05:22Z

Eliminates support for the "number of requested links" field in a neighbor discovery message. This field was never used and has been removed from the TIPC 2.0 protocol specification. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Remove support for per-connection message sequence numbering

2011-02-23T23:05:21Z

Eliminates TIPC's prototype support for message sequence numbering on routable connections (i.e. connections requiring more than one hop). This capability isn't currently used, and can be removed since TIPC only supports systems in which all inter-node communication can be achieved in a single hop.

tipc: remove extraneous braces from single statements

2011-01-01T21:57:57Z

Cleans up TIPC's source code to eliminate the presence of unnecessary use of {} around single statements. These changes are purely cosmetic and do not alter the operation of TIPC in any way. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: cleanup various cosmetic whitespace issues

2011-01-01T21:57:56Z

Cleans up TIPC's source code to eliminate deviations from generally accepted coding conventions relating to leading/trailing white space and white space around commas, braces, cases, and sizeof. These changes are purely cosmetic and do not alter the operation of TIPC in any way. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: remove redundant #includes

2011-01-01T21:57:54Z

Eliminates a number of #include statements that no longer serve any useful purpose. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: Finish streamlining of debugging code

2011-01-01T21:57:54Z

Completes the simplification of TIPC's debugging capabilities. By default TIPC includes no debugging code, and any debugging code added by developers that calls the dbg() and dbg_macros() is compiled out. If debugging support is enabled, TIPC prints out some additional data about its internal state when certain abnormal conditions occur, and any developer-added calls to the TIPC debug macros are compiled in.
