9c7ee5a21e Tear out old "link quality" stuff since it is not currently used and will be done differently. 2018-01-08 13:06:24 -08:00

b1d60df44c timestamps changed from uint64_t to int64_t
There were cases in the code where time calculations and comparisons were overflowing and causing connection instability.  This will keep time calculations within expected ranges.

1d39be61b2 ZeroTier now has link quality measurement. We are not using this yet but decided to put it in to prep for future QoS support and SD-WAN stuff. 2017-03-01 14:36:52 -08:00

5b6d27e659 Implement relay policy, and setting multicast limit to 0 now disables multicast on the network as would be expected. 2016-09-13 14:27:18 -07:00

8ef0e4bbaf Get rid of HELLO rate gate on path since its basically worthless. There are 65535 ports per IP. 2016-09-13 10:46:36 -07:00
Adam Ierymenko
ab9afbc749 (1) Public networks now get COMs even though they do not gate with them since they will need them to push auth for multicast stuff, (2) added a bunch of rate limit circuit breakers for anti-DOS, (3) cleanup. 2016-09-09 11:36:10 -07:00

584228b2b5 Dead code removal, and get rid of reliable() because we will no longer make that distinction. 2016-08-24 17:56:35 -07:00
Adam Ierymenko
2c995f1f91 IPv6 links are unfortunately not "reliable." Many IPv6 gateways, while not
implementing NAT, do implement stateful firewalling with absurdly short
timeouts (<60s). Keepalives are still required in IPv6.

Network engineers continue to mindlessly carry forward cruft and baggage
from IPv4 to IPv6.

2f18a92e20 Cleanup in numerous places, reduce network chattiness around MULTICAST_LIKE, and fix a "how was that working" latent bug causing some control traffic to take the scenic route. 2016-04-19 12:09:35 -07:00

4c455876f9 Revise peer path weighting to always prioritize cluster-optimal paths. 2016-04-19 09:22:51 -07:00

82348e1537 Temporarily blacklist he.net IPv6 tunnel addresses for paths: these usually have a very low MTU which causes packet loss and other issues. 2016-02-10 11:06:26 -08:00

63ec7e58d4 Make activity no longer a function of ping frequency, since this causes compatibility bugs when the latter was modified due to timer interactions with other versions. 2016-02-08 10:03:01 -08:00

05b2c0743f Tighten up dead path detection. Should now auto-detect dead paths in less than 10 seconds at a very small cost in ECHO requests (or HELLOs for older peers). GitHib issue #272 2016-01-06 10:00:03 -08:00

35c4e28f31 Mark geo-redirected paths as suboptimal and do not report that we have a peer if all we have is one of these. Also a few other small fixes. 2015-11-09 14:25:28 -08:00
