80ba24d512 force things to buffer in the switch if the best link is currently busy. note that other links can end up sending if they become non-idle for other reasons. this is a temporary workaround to packet reordering, until we can figure out a better solution 2019-09-17 19:42:07 -05:00

8c52ccadf9 make dial fail if a session to the same node already exists, fixes race between simultaneous connections to a node's 200 address and one of its 300 addresses, should also fix races between a search and an accepted listen 2019-09-01 14:07:00 -05:00

d08c2eb237 stop exporting ReadNoCopy and WriteNoCopy, since we use the actor functions / callbacks and everything else should use Read and Write instead... 2019-09-01 13:04:10 -05:00

cabdc27a54 change how nonce is tracked, so we allow packets if we've recently received a highest nonce ever, but don't bother tracking all received nonce values, this means duplicate packets are possible but only for a small window of time (and significantly reduces memory usage per session) 2019-08-31 17:39:05 -05:00
