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: 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: 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: Fix port counter handling to correct congestion control

2011-02-23T23:05:18Z

Modifies TIPC's congestion control between a connected port and its peer so that it works as documented. The following changes have been made: 1) The counter of the number of messages sent by a port now starts at zero, rather than one. This prevents the port from reporting port congestion one message earlier than it was supposed to. 2) The counter of the number of messages sent by a port is now incremented only if a non-empty message is sent successfully. This prevents the port from becoming permanently congested if too many send attempts are unsuccessful because of congestion (or other reasons). It also removes the risk that empty hand- shaking messages used during connection setup might cause the port to report congestion earlier than it was supposed to. 3) The counter of the number of unacknowledged messages received by a port controlled by an internal TIPC service is now incremented only if the message is non-empty, in order to be consistent with the aforementioned changes.

tipc: Combine port structure with tipc_port structure

2011-02-23T23:04:27Z

Merge two distinct structures containing information about a TIPC port into a single structure. The structures were previously kept separate so that public information about a port could be made available to applications using TIPC's native API, while the remaining information was kept private for use by TIPC itself. However, now that the native API has been removed there is no longer any need for this somewhat confusing arrangement. Since one of the structures was already embedded within the other, the change largely involves replacing instances of "publ.foo" with "foo". The changes do not otherwise alter the operation of TIPC ports. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker

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 calls to dbg() and msg_dbg()

2011-01-01T21:57:52Z

Eliminates obsolete calls to two of TIPC's main debugging macros, as well as a pair of associated debugging routines that are no longer required. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: Remove user registry subsystem

2011-01-01T21:57:51Z

Eliminates routines, data structures, and files that make up TIPC's user registry. The user registry is no longer needed since the native API routines that utilized it no longer exist and there are no longer any internal TIPC services that use it.

tipc: Delete tipc_ownidentity()

2010-12-02T21:34:06Z

Moves the content of the native API routine tipc_ownidentity() into the sole routine that calls it, since it can no longer be called in isolation. Signed-off-by: Allan Stephens Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

tipc: Eliminate obsolete native API forwarding routines

2010-12-02T21:34:06Z

Moves the content of each native API message forwarding routine into the sole routine that calls it, since the forwarding routines no longer be called in isolation. Also removes code in each routine that altered the outgoing message's importance level since this is now no longer possible. The previous function mapping (parent function, and child API) was as follows: tipc_send2name \--tipc_forward2name tipc_send2port \--tipc_forward2port tipc_send_buf2port \--tipc_forward_buf2port After this commit, the children don't exist and their functionality is completely in the respective parent.
