* tipc: Add missing locks in broadcast link statistics accumulationAllan Stephens2012-02-061-0/+11
| | | | | | | | | | Ensures that all attempts to update broadcast link statistics are done only while holding the lock that protects the link's main data structures, to prevent interference by simultaneous updates caused by messages arriving on other interfaces.

* tipc: Fix bug in broadcast link duplicate message statisticsAllan Stephens2012-02-061-0/+2
| | | | | | | | | | Modifies broadcast link so that it increments the "received duplicate message" count if an incoming message cannot be added to the deferred message queue because it is already present in the queue. (The aligns broadcast link behavior with that of TIPC's unicast links.) Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* tipc: Fix node lock reclamation issues in broadcast link receptionAllan Stephens2012-02-061-18/+40
| | | | | | | | | | | | | | | | Fixes a pair of problems in broadcast link message reception code relating to the reclamation of the node lock after consuming an in-sequence message. 1) Now retests to see if the sending node is still up after reclaiming the node lock, and bails out if it is non-operational. 2) Now manipulates the node's deferred message queue only after reclaiming the node lock, rather than using queue head pointer information that was cached previously.

* tipc: Add missing broadcast link lock when sending NACKAllan Stephens2012-02-061-0/+2
| | | | | | | | | | Ensures that any attempt to send a NACK message over TIPC's broadcast link has exclusive access to the link's main data structures, to prevent interference with a simultaneous attempt to send other broadcast link traffic (such as application-generated multicast messages).

* tipc: Fix problem with broadcast link synchronization between nodesAllan Stephens2012-02-061-2/+5
| | | | | | | | | | | | | | Corrects a problem in which a link endpoint that activates as the result of receiving a RESET/STATE sequence of link protocol messages fails to properly record the broadcast link status information about the node to which it is now communicating with. (The problem does not occur with the more common RESET/ACTIVATE sequence of messages.) The fix ensures that the broadcast link status info is updated after the RESET message resets the link endpoint, rather than before, thereby preventing new information from being overwritten by the reset operation.

* tipc: Ensure broadcast link re-acquires node after link failureAllan Stephens2012-02-063-4/+8
| | | | | | | | | | | | | | | | | | | | | | | Fix a bug that can prevent TIPC from sending broadcast messages to a node if contact with the node is lost and then regained. The problem occurs if the broadcast link first clears the flag indicating the node is part of the link's distribution set (when it loses contact with the node), and later fails to restore the flag (when contact is regained); restoration fails if contact with the node is regained by implicit unicast link activation triggered by the arrival of a data message, rather than explicitly by the arrival of a link activation message. The broadcast link now uses separate fields to track whether a node is theoretically capable of receiving broadcast messages versus whether it is actually part of the link's distribution set. The former member is updated by the receipt of link protocol messages, which can occur at any time; the latter member is updated only when contact with the node is gained or lost. This change also permits the simplification of several conditional expressions since the broadcast link's "supported" field can now only be set if there are working links to the associated node.

* tipc: Prevent broadcast link stalling in dual LAN environmentsAllan Stephens2012-02-061-4/+5
| | | | | | | | | | | | | | | | | | Ensure that sequence number information about incoming broadcast link messages is initialized only by the activation of the first link to a given cluster node. Previously, a race condition allowed reset and/or activation messages for a second link to re-initialize this sequence number information with obsolete values. This could trigger TIPC to request the retransmission of previously acknowledged broadcast link messages from that node, resulting in broadcast link processing becoming stalled if the node had already released one or more of those messages and was unable to perform the required retransmission. Thanks to Laser <gotolaser@gmail.com> for identifying this problem and assisting in the development of this fix.

* tipc: Prevent transmission of outdated link protocol messagesAllan Stephens2012-02-061-26/+27
| | | | | | | | | | | | | | | | Ensures that a link endpoint discards any previously deferred link protocol message whenever it attempts to send a new one. Previously, it was possible for a link protocol message that was unsent due to congestion to be transmitted after newer protocol messages had been sent. The stale link protocol message might then cause the receiving link endpoint to malfunction because of its outdated conent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the flexcan driver uses hardware local echo. This blindly echos all transmitted frames to all receiving sockets, regardless what CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to. This patch now submits transmitted frames to be echoed in the transmit complete interrupt, preserving the reference to the sending socket. This allows the can protocol to correctly handle the local echo. Further this patch moves tx_bytes statistic accounting into the tx_complete handler.

In case of negative values a condition is triggered and the function return -128dBm while the signal is at its maximum.
