* tipc: Remove support for per-connection message sequence numberingAllan Stephens2011-02-231-28/+1
| | | | | | | | | | | 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 controlAllan Stephens2011-02-231-19/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 structureAllan Stephens2011-02-231-117/+117
| | | | | | | | | | | | | | | | | 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 <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* tipc: Remove prototype code for supporting slave nodesAllan Stephens2011-01-011-4/+1
| | | | | | | | | | | | | | | | | Simplifies routines and data structures that were intended to allow TIPC to support slave nodes (i.e. nodes that did not have links to all of the other nodes in its cluster, forcing TIPC to route messages that it could not deliver directly through a non-slave node). Currently, TIPC supports only networks containing non-slave nodes, so this code is unnecessary. Note: The latest edition of the TIPC 2.0 Specification has eliminated the concept of slave nodes entirely.

| | | | | | | | | | | | Optimizes TIPC's name table translation code to avoid unnecessary manipulation of the node address field of the resulting port id when name translation fails.

This change eliminates the need for a mutex in the TIPC-specific portion of the socket protocol data structure -- in its place, the standard Linux socket backlog queue and associated locking routines are utilized.

* [TIPC]: Optimize stream send routine to avoid fragmentationAllan Stephens2007-07-101-5/+5
| | | | | | | | | | | | | | | | | | | | This patch enhances TIPC's stream socket send routine so that it avoids transmitting data in chunks that require fragmentation and reassembly, thereby improving performance at both the sending and receiving ends of the connection. The "maximum packet size" hint that records MTU info allows the socket to decide how big a chunk it should send; in the event that the hint has become stale, fragmentation may still occur, but the data will be passed correctly and the hint will be updated in time for the following send. Note: The 66060 byte pseudo-MTU used for intra-node connections requires the send routine to perform an additional check to ensure it does not exceed TIPC"s limit of 66000 bytes of user data per chunk.

* [TIPC]: Remove inlines from *.cSam Ravnborg2006-03-201-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With reference to latest discussions on linux-kernel with respect to inline here is a patch for tipc to remove all inlines as used in the .c files. See also chapter 14 in Documentation/CodingStyle. Before: text data bss dec hex filename 102990 5292 1752 110034 1add2 tipc.o Now: text data bss dec hex filename 101190 5292 1752 108234 1a6ca tipc.o This is a nice text size reduction which will improve icache usage. In some cases bigger (> 4 lines) functions where declared inline and used in many places, they are most probarly no longer inlined by gcc resulting in the size reduction. There are several one liners that no longer are declared inline, but gcc should inline these just fine without the inline hint. With this patch applied one warning is added about an unused static function - that was hidded by utilising inline before. The function in question were kept so this patch is solely a inline removal patch.
