2010-08-18tipc: Prevent missing name table entries when link flip-flops rapidlyAllan Stephens1-0/+8
Ensure that TIPC does not re-establish communication with a neighboring node until it has finished updating all data structures containing information about that node to reflect the earlier loss of contact. Previously, it was possible for TIPC to perform its purge of name table entries relating to the node once contact had already been re-established, resulting in the unwanted removal of valid name table entries.

2010-05-13tipc: add tipc_ prefix to fcns targeted for un-inliningAllan Stephens1-3/+3
These functions have enough code in them such that they seem like sensible targets for un-inlining. Prior to doing that, this adds the tipc_ prefix to the functions, so that in the event of a panic dump or similar, the subsystem from which the functions come from is immediately clear.

2010-05-13tipc: Relocate trivial link status functions to header fileAllan Stephens1-1/+1
Rather than live in link.c where they can only be used in that file alone, these helper routines are better served by being in link.h Relocated are the following: link_working_working link_working_unknown link_reset_unknown link_reset_reset link_blocked link_congested Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.

2008-09-03tipc: Don't use structure names which easily globally conflict.David S. Miller1-1/+1
Andrew Morton reported a build failure on sparc32, because TIPC uses names like "struct node" and there is a like named data structure defined in linux/node.h This just regexp replaces "struct node*" to "struct tipc_node*" to avoid this and any future similar problems.

2008-06-05tipc: Message rejection rework preparatory changesAllan Stephens1-1/+1
This patch defines a few new message header manipulation routines, and generalizes the usefulness of another, in preparation for upcoming rework of TIPC's message rejection code. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-05tipc: Optimize message initialization routineAllan Stephens1-2/+1
This patch eliminates the rarely-used "error code" argument when initializing a TIPC message header, since the default value of zero is the desired result in most cases; the few exceptional cases now set the error code explicitly.

2008-06-05tipc: Minor optimizations to received message processingAllan Stephens1-2/+2
This patch enhances TIPC's handler for incoming messages in two ways: - the trivial, single-use routine for processing non-sequenced messages has been merged into the main handler - the interface that received a message is now identified without having to access and/or modify the associated sk_buff Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-05-22tipc: Optimize null pointer check during neighbor discoveryAllan Stephens1-3/+2
This patch optimizes TIPC neighbor discovery code to avoid testing for a null node pointer when the pointer is already known to be non-null. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-10-19[TIPC]: Fixed slow link reactivation when link tolerance is largeAllan Stephens1-3/+4
This patch corrects an issue wherein a previouly failed node could not reestablish a links to a non-failing node in the TIPC network until the latter node detected the link failure itself (which might be configured to take up to 30 seconds). The non-failing node now responds to link setup requests from a previously failed node in at most 1 second, allowing it to detect the link failure more quickly.

2006-10-19[TIPC]: Added duplicate node address detection capabilityAllan Stephens1-1/+31
TIPC now rejects and logs link setup requests from node <Z.C.N> if the receiving node already has a functional link to that node on the associated interface, or if the requestor is using the same <Z.C.N> as the receiver.
