cc1b275ad9 Replicate peer endpoints and forget paths if we have them -- this allows two clusters to talk to each other, whereas forgetting all paths does not. 2015-10-27 16:47:13 -07:00
Adam Ierymenko
a1a0ee4edb Fix infinite loop in Cluster, clean up some stuff elsewhere, and back out rate limiting in PUSH_DIRECT_PATHS for now (but we will do something else to mitigate amplification attacks) 2015-10-27 12:01:00 -07:00

7d62dbe9f7 Tune NAT-t keepalives so that timing is better obeyed, clean up a build warning, and fix a potential source of network recursion (though harmless). 2015-10-07 11:57:59 -07:00

f69454ec98 (1) Make ZT_ naming convention consistent (get rid of ZT1_), (2) Make local interface a full sockaddr_storage instead of an int identifier, which turns out to be better for multi-homing and other uses. 2015-09-24 16:21:36 -07:00

d647a587a1 (1) Fix updating of network revision counter on member change.
(2) Go back to timestamp as certificate revision number. This is simpler
    and more robust than using the network revision number for this and
    forcing network revision fast-forward, which could cause some peers
    to fall off the horizon when you don't want them to.

d9006712f6 Completely factor out "desperation" from the core. I thought of a significantly simpler way to move all of this logic entirely into the containing service, liberating the core from any concern over the nature of its pipe to the outside world. 2015-05-21 15:58:26 -07:00
