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: Cosmetic consolidation of internal message type definitions

2011-05-10T20:03:45Z

Half of the #define entries in msg.h were down at the bottom of the header, instead of up at the top before any of the static inlines etc. Relocate them up to the top, to be consistent with the other normal linux header file layout conventions.

tipc: Eliminate unused routing message definitions

2011-05-10T20:03:44Z

Gets rid of unused constants defining the types used in routing messages. These messages no longer exist in TIPC now that multicluster and multizone support has been eliminated. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

tipc: Update comments in message header include file

2011-05-10T20:03:36Z

Removes comments in TIPC's message header include file that are outdated and/or unnecessary. Also introduces short comments (or supplements existing ones) to better describe several set of existing symbolic constants. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

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 unnecessary constant for neighbor discovery msg size

2011-03-13T20:35:18Z

Eliminates an unnecessary constant that defines the size of a LINK_CONFIG message, and uses one of the existing standard message size symbols in its place. (The defunct constant was located in the wrong place anyway, since it was grouped with other constants that define message users instead of message sizes.)

tipc: make msg_set_redundant_link() consistent with other set ops

2011-03-13T20:35:17Z

All the other boolean like msg_set_X(m) operations don't export both a msg_set_X(a) and a msg_clear_X(m), but instead just have the single msg_set_X(m, val) variant. Make the redundant_link one consistent by having the set take a value, and delete the msg_clear_redundant_link() anomoly. This is a cosmetic change and should not change behaviour.

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
