* tipc: Detect duplicate nodes using different network interfacesAllan Stephens2012-02-241-14/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Utilizes the new "node signature" field in neighbor discovery messages to ensure that all links TIPC associates with a given <Z.C.N> network address belong to the same neighboring node. (Previously, TIPC could not tell if link setup requests arriving on different interfaces were from the same node or from two different nodes that has mistakenly been assigned the same network address.) The revised algorithm for detecting a duplicate node considers both the node signature and the network interface adddress specified in a request message when deciding how to respond to a link setup request. This prevents false alarms that might otherwise arise during normal network operation under the following scenarios: a) A neighboring node reboots. (The node's signature changes, but the network interface address remains unchanged.) b) A neighboring node's network interface is replaced. (The node's signature remains unchanged, but the network interface address changes.) c) A neighboring node is completely replaced. (The node's signature and network interface address both change.) The algorithm also handles cases in which a node reboots and re-establishes its links to TIPC (or begins re-establishing those links) before TIPC detects that it is using a new node signature. In such cases of "delayed rediscovery" TIPC simply accepts the new signature without disrupting communication that is already underway over the links.

* tipc: Introduce node signature field in neighbor discovery messageAllan Stephens2012-02-241-0/+3
| | | | | | | | | | | | | | | | | Adds support for the new "node signature" in neighbor discovery messages, which is a 16 bit identifier chosen randomly when TIPC is initialized. This field makes it possible for nodes receiving a neighbor discovery message to detect if multiple neighboring nodes are using the same network address (i.e. <Z.C.N>), even when the messages are arriving on different interfaces. This first phase of node signature support creates the signature, incorporates it into outgoing neighbor discovery messages, and tracks the signature used by valid neighbors. An upcoming patch builds on this foundation to implement the improved duplicate neighbor detection checking.

* tipc: Ignore neighbor discovery messages containing invalid addressAllan Stephens2011-12-271-0/+3
| | | | | | | | | | Adds a check to ensure that TIPC ignores an incoming neighbor discovery message that specifies an invalid media address as its source. The check ensures that the source address is a valid, non-broadcast address that could legally be used by a neighboring link endpoint.

* tipc: Hide media-specific addressing details from generic bearer codeAllan Stephens2011-12-271-2/+2
| | | | | | | | | | | | | | | | Reworks TIPC's media address data structure and associated processing routines to transfer all media-specific details of address conversion to the associated TIPC media adaptation code. TIPC's generic bearer code now only needs to know which media type an address is associated with and whether or not it is a broadcast address, and totally ignores the "value" field that contains the actual media-specific addressing info. These changes eliminate the need for a number of endianness conversion operations and will make it easier for TIPC to support new media types in the future.

* tipc: Ensure both nodes recognize loss of contact between themAllan Stephens2011-09-181-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* tipc: Revise timings used when sending link request messagesAllan Stephens2011-05-101-30/+36
| | | | | | | | | | | | | | | | | | | | Revises the algorithm governing the sending of link request messages to take into account the number of nodes each bearer is currently in contact with, and to ensure more rapid rediscovery of neighboring nodes if a bearer fails and then recovers. The discovery object now sends requests at least once a second if it is not in contact with any other nodes, and at least once a minute if it has at least one neighbor; if contact with the only neighbor is lost, the object immediately reverts to its initial rapid-fire search timing to accelerate the rediscovery process. In addition, the discovery object now stops issuing link request messages if it is in contact with the only neighboring node it is configured to communicate with, since further searching is unnecessary.

| | | | | | | | | | | | | | Modifies bearer creation and deletion code to improve handling of scenarios when a neighbor discovery object cannot be created. The creation routine now aborts the creation of a bearer if its discovery object cannot be created, and deletes the newly created bearer, rather than failing quietly and leaving an unusable bearer hanging around. Since the exit via the goto label really isn't a definitive failure in all cases, relabel it appropriately.

| | | | | | | | | | | | | Enhances existing checks on the discovery domain associated with a TIPC bearer. A bearer can no longer be configured to accept links from itself only (which would be pointless), or to nodes outside its own cluster (since multi-cluster support has now been removed from TIPC).

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Delay releasing the node lock when processing a neighbor discovery message until after the optional discovery response message has been sent. This helps ensure that any link protocol messages sent by a link endpoint created as a result of a neighbor discovery request are received after the discovery response is received, thereby giving the receiving node a chance to create a peer link endpoint to consume those link protocol messages, if one does not already exist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reworks the appearance of the routine that processes incoming LINK_CONFIG messages to keep the main logic flow at a consistent level of indentation, and to add comments outlining the various phases involved in processing each message. This rework is being done to allow upcoming enhancements to this routine to be integrated more cleanly. The diff isn't really readable, so know that it was a case of the old code being like: tipc_disc_recv_msg(..) { if (in_own_cluster(orig)) { ... lines and lines of stuff ... } } which is now replaced with the more sane: tipc_disc_recv_msg(..) { if (!in_own_cluster(orig)) return; ... lines and lines of stuff ... } Instances of spin locking within the reindented block were replaced with the identical tipc_node_[un]lock() abstractions. Note that all these changes are cosmetic in nature, and do not change the way LINK_CONFIG messages are processed.

* tipc: Combine bearer structure with tipc_bearer structureAllan Stephens2011-02-241-13/+13
| | | | | | | | | | | | | | | | Combines two distinct structures containing information about a TIPC bearer into a single structure. The structures were previously kept separate so that public information about a bearer could be made available to plug-in media types 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 arrangement. Since one of the structures was already embedded within the other, the change largely involves replacing instances of "publ.foo" with "foo".
