Rafael H. Schloming commented on PROTON-200:
--------------------------------------------
I'd say first priority for 0.4 is the -1 fix. My sense is re-balancing properly
is going to be a 0.5 thing, however if we get the -1 fix in and have extra time
and it turns out to be low risk, I'm not opposed to rebalancing for 0.4.
On the DoS topic, while I agree there are a number of potential DoSes here, I
don't think the -1 patch really makes them any worse. In some ways the DoS
issue is orthogonal. Currently we could be DoSed anyways by simply holding
connections open without involving links at all. I think to address the DoS
issue we need a more general inactivity timer. With that in place it would not
only address a more general class of DoS, but in this case it would cause the
links held by that client to close and their credit to be reclaimed (i.e. doing
a primitive destructive sort of rebalancing).
