2011-03-13tipc: Optimizations to link creation codeAllan Stephens1-1/+1
Enhances link creation code as follows: 1) Detects illegal attempts to add a requested link earlier in the link creation process. This prevents TIPC from wasting time initializing a link object it then throws away, and also eliminates the code needed to do the throwing away. 2) Passes in the node object associated with the requested link. This allows TIPC to eliminate a search to locate the node object, as well as code that attempted to create the node if it doesn't exist.

2011-03-13tipc: cosmetic - function names are not to be full sentencesPaul Gortmaker1-2/+2
Function names like "tipc_node_has_redundant_links" are unweildy and result in long lines even for simple lines. The "has" doesn't contribute any value add, so dropping that is a slight step in the right direction. This is a cosmetic change, basic result of: for i in `grep -l tipc_node_has_ *` ; do sed -i s/tipc_node_has_/tipc_node_/ $i ; done Signed-off-by: Paul Gortmaker <[email protected]>
2011-03-13tipc: Convert node object array to a hash tableAllan Stephens1-10/+20
Replaces the dynamically allocated array of pointers to the cluster's node objects with a static hash table. Hash collisions are resolved using chaining, with a typical hash chain having only a single node, to avoid degrading performance during processing of incoming packets. The conversion to a hash table reduces the memory requirements for TIPC's node table to approximately the same size it had prior to the previous commit. In addition to the hash table itself, TIPC now also maintains a linked list for the node objects, sorted by ascending network address. This list allows TIPC to continue sending responses to user space applications that request node and link information in sorted order. The list also improves performance when name table update messages are sent by making it easier to identify the nodes that must be notified.

2011-03-13tipc: Split up unified structure of network-related variablesAllan Stephens1-1/+1
Converts the fields of the global "tipc_net" structure into individual variables. Since the struct was never referenced as a complete unit, its existence was pointless. This will facilitate upcoming changes to TIPC's node table and simpify upcoming relocation of the variables so they are only visible to the files that actually use them. This change is essentially cosmetic in nature, and doesn't affect the operation of TIPC. Signed-off-by: Allan Stephens <[email protected]> Signed-off-by: Paul Gortmaker <[email protected]>
2011-01-01tipc: Remove prototype code for supporting multiple clustersAllan Stephens1-4/+3
Eliminates routines, data structures, and files that were intended to allow TIPC to support a network containing multiple clusters. Currently, TIPC supports only networks consisting of a single cluster within a single zone, so this code is unnecessary.

2010-10-16tipc: cleanup function namespacestephen hemminger1-1/+0
Do some cleanups of TIPC based on make namespacecheck 1. Don't export unused symbols 2. Eliminate dead code 3. Make functions and variables local 4. Rename buf_acquire to tipc_buf_acquire since it is used in several files Compile tested only. This make break out of tree kernel modules that depend on TIPC routines.

2010-08-17tipc: Prevent missing name table entries when link flip-flops rapidlyAllan Stephens1-0/+2
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.

2008-09-02tipc: Don't use structure names which easily globally conflict.David S. Miller1-21/+21
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.

2006-06-25[TIPC]: Fixed link switchover bugsAllan Stephens1-0/+2

2006-03-20[TIPC]: Fix simple sparse warningsSam Ravnborg1-1/+1
Tried to run the new tipc stack through sparse. Following patch fixes all cases where 0 was used as replacement of NULL. Use NULL to document this is a pointer and to silence sparse. This brough sparse warning count down with 127 to 24 warnings. Signed-off-by: Sam Ravnborg <[email protected]> Signed-off-by: Per Liden <[email protected]> Signed-off-by: David S.
