2011-10-31net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modulesPaul Gortmaker
These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31net: Fix files explicitly needing to include module.hPaul Gortmaker
With calls to modular infrastructure, these files really needs the full module.h header. Call it out so some of the cleanups of implicit and unrequired includes elsewhere can be cleaned up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-09-17tipc: Enhance sending of bulk name table messagesAllan Stephens
Modifies the initial transfer of name table entries to a new neighboring node so that the messages are enqueued as a unit, rather than individually. The revised algorithm now locates the link carrying the message only once, and eliminates unnecessary checks for link congestion, message fragmentation, and message bundling that are not required when sending these messages.

2011-09-17tipc: relocate/coalesce node cast in tipc_named_node_upPaul Gortmaker
Functions like this are called using unsigned longs from function pointers. In this case, the function is passed in a node which is normally internally treated as a u32 by TIPC. Rather than add more casts into this function in the future for each added use of node within, move the cast to a single place on a local. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-17tipc: Prevent fragmented messages during initial name table exchangeAllan Stephens
Reduces the maximum size of messages sent during the initial exchange of name table information between two nodes to be no larger than the MTU of the first link established between the nodes. This ensures that messages will never need to be fragmented, which would add unnecessary overhead to the name table synchronization mechanism.

2011-09-17tipc: Lower limits for number of bearers and media typesAllan Stephens
Reduces the number of bearers a node can support to 2, which can use identical or non-identical media. This change won't impact users, since they are currently limited to a maximum of 2 Ethernet bearers, and will save memory by eliminating a number of unused entries in TIPC's media and bearer arrays.

2011-09-17tipc: Ensure both nodes recognize loss of contact between themAllan Stephens
Enhances TIPC to ensure that a node that loses contact with a neighboring node does not allow contact to be re-established until it sees that its peer has also recognized the loss of contact. Previously, nodes that were connected by two or more links could encounter a situation in which node A would lose contact with node B on all of its links, purge its name table of names published by B, and then fail to repopulate those names once contact with B was restored. This would happen because B was able to re-establish one or more links so quickly that it never reached a point where it had no links to A -- meaning that B never saw a loss of contact with A, and consequently didn't re-publish its names to A. This problem is now prevented by enhancing the cleanup done by TIPC following a loss of contact with a neighboring node to ensure that node A ignores all messages sent by B until it receives a LINK_PROTOCOL message that indicates B has lost contact with A, thereby preventing the (re)establishment of links between the nodes. The loss of contact is recognized when a RESET or ACTIVATE message is received that has a "redundant link exists" field of 0, indicating that B's sending link endpoint is in a reset state and that B has no other working links. Additionally, TIPC now suppresses the sending of (most) link protocol messages to a neighboring node while it is cleaning up after an earlier loss of contact with that node. This stops the peer node from prematurely activating its link endpoint, which would prevent TIPC from later activating its own end. TIPC still allows outgoing RESET messages to occur during cleanup, to avoid problems if its own node recognizes the loss of contact first and tries to notify the peer of the situation. Finally, TIPC now recognizes an impending loss of contact with a peer node as soon as it receives a RESET message on a working link that is the peer's only link to the node, and ensures that the link protocol suppression mentioned above goes into effect right away -- that is, even before its own link endpoints have failed. This is necessary to ensure correct operation when there are redundant links between the nodes, since otherwise TIPC would send an ACTIVATE message upon receiving a RESET on its first link and only begin suppressing when a RESET on its second link was received, instead of initiating suppression with the first RESET message as it needs to. Note: The reworked cleanup code also eliminates a check that prevented a link endpoint's discovery object from responding to incoming messages while stale name table entries are being purged. This check is now unnecessary and would have slowed down re-establishment of communication between the nodes in some situations.

2011-09-01tipc: Discard incoming broadcast messages that are unexpectedAllan Stephens
Modifies TIPC's incoming broadcast packet handler to discard messages that cannot legally be sent over the broadcast link, including: - broadcast protocol messages that do no contain state information - payload messages that are not named multicast messages - any other form of message except for bundled messages, fragmented messages, and name distribution messages. These checks are needed to prevent TIPC from handing an unexpected message to a routine that isn't prepared to handle it, which could lead to incorrect processing (up to and including invalid memory references caused by attempts to access message fields that aren't present in the message).

2011-09-01tipc: Prevent broadcast link stalling when another node failsAllan Stephens
Ensure that broadcast link messages that have not been acknowledged by a newly failed node do not get an implied acknowledgement until the failed node is removed from the broadcast link's map of reachable nodes. Previously, a race condition allowed a new broadcast link message to be sent after the implicit acknowledgement processing was completed, but before the map of reachable nodes was updated, resulting in the message having an expected acknowledgement count that required the failed node to explicitly acknowledge the message. Since this would never occur the new message would remain in the broadcast link's transmit queue forever, eventually causing the link to become congested and "stall". Delaying the implicit acknowledgement processing until after the update of the map of reachable nodes eliminates this race condition and prevents stalling.

2011-09-01tipc: Enhance cleanup of broadcast link when contact with node is lostAllan Stephens
Enhances cleanup of broadcast link-related information when contact with a node is lost. 1) All broadcast link-related cleanup now occurs only if the lost node was capable of communicating over the broadcast link. 2) Following cleanup, the lost node is marked as no longer supporting the broadcast link, ensuring that any remaining broadcast messages received from that node prior to the re-establishment of a normal communication link are ignored.

Ensure TIPC ignores an out-dated link reset message whose session number predates the current session number. (Previously, TIPC only ignored an out-date reset message whose session number was equal to the current link session number.) Out-dated link reset messages should not occur under normal circumstances; however, they can be generated if a link endpoint is unable to send a link reset message right away and queues it for later delivery, but the queued message is not sent until after the link is established.

Restructures the logic used in tipc_port_recv_proto_msg() to ensure that incoming connection protocol messages are handled properly.

2011-06-24tipc: Optimize creation of FIN messagesAllan Stephens
Speeds up the creation of the FIN message that terminates a TIPC connection.

Modifies the main circular linked lists of publications used in TIPC's name table to use the standard kernel linked list type.

2011-06-24tipc: Partition name table instance array info into two partsAllan Stephens
Modifies the name table array structure that contains the name sequence instances for a given name type so that the publication lists associated with a given instance are stored in a dynamically allocated structure, rather than being embedded within the array entry itself. This change is being done for several reasons: 1) It reduces the amount of data that needs to be copied whenever a given array is expanded or contracted to accommodate the first publication of a new name sequence or the removal of the last publication of an existing name sequence. 2) It reduces the amount of memory associated with array entries that are currently unused. 3) It facilitates the upcoming conversion of the publication lists from TIPC-specific circular lists to standard kernel lists. (Standard lists cannot be used with the former array structure because the relocation of array entries during array expansion and contraction would corrupt the lists.) Note that, aside from introducing a small amount of code to dynamically allocate and free the structure that now holds publication list info, this change is largely a simple renaming exercise that replaces references to "sseq->LIST" with "sseq->info->LIST" (or "info->LIST").

2011-06-24tipc: Optimizations & corrections to message rejectionAllan Stephens
Optimizes the creation of a returned payload message by duplicating the original message and then updating the small number of fields that need to be adjusted, rather than building the new message header from scratch. In addition, certain operations that are not always required are relocated so that they are only done if needed. These optimizations also have the effect of addressing other issues that were present previously: 1) Fixes a bug that caused the socket send routines to return the size of the returned message, rather than the size of the sent message, when a returnable payload message was sent to a non-existent destination port. 2) The message header of the returned message now matches that of the original message more closely. The header is now always the same size as the original header, and some message header fields that weren't being initialized in the returned message header are now populated correctly -- namely the "d" and "s" bits, and the upper bound of a multicast name instance (where present).
