This commit fixes a possible deadlock within the packetQueue that could be caused by the following circular waiting dependency: packetCoordinator woken up, grabs lock, queue isn’t empty, attempts to send packet to link (lock still held) -> channelLink has commitment overflow, attempts to add new item to packet queue, in AddPkt grabs Lock -> circular wait. We avoid this scenario by *not* holding the lock within the packetCoordinator when we attempt to send a new packet to the switch. Instead, we release the lock before the second select statement in the main processing loop. |
