e4896b257f Add thread PTR that gets passed through the entire ZT core call stack and then passed to handler functions resulting from a call. 2017-03-27 17:03:17 -07:00

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

2bf9145ae6 Outgoing side of packet counter for link quality reporting. Also some cleanup and a cluster mode build fix. 2017-03-01 10:22:57 -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

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

a7d988745b Use ECHO instead of HELLO where possible. 2016-09-07 12:01:03 -07:00

48a374c82c (1) fix crazy bug introduced in doRENDEZVOUS(), (2) reclaim Paths after paths[] condense, (3) fix an edge case around symmetric NAT and external IP change detection. 2016-09-06 14:05:58 -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

d8143a5e18 Implement first pass on rapid dead path detection, and increment version to 1.1.3 (dev) 2016-01-05 16:41:54 -08:00

436c1fac1d Selectively move over changes from "edge" to "dev" excluding netcon. 2015-12-21 16:15:39 -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

a994573a43 Eliminate some more dead code. We may do path trust, but not like that. 2015-10-29 09:42:15 -07:00

51fcc75354 Some cleanup, and use getPeerNoCache() exclusively in Cluster. 2015-10-27 17:36:47 -07:00

11ff96ba1d Consider IPv6 paths reliable (no constant keepalives needed) 2015-09-30 15:20:08 -07:00
Adam Ierymenko
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

0b354803f3 Clean up some YAGNI issues with implementation of GitHub issue #180, and make best path choice aware of path rank. 2015-07-13 10:03:04 -07:00
Adam Ierymenko
c863ff3f02 A bunch of comments and cleanup, including some to yesterday's direct path pushing changes. Move path viability check to one place, and stop trying to use link-local addresses since they are not reliable. 2015-07-07 08:54:48 -07:00

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
Adam Ierymenko
49f031ccb4 Tons of refactoring, change to desperation algorithm to use max of core or link, porting over core loop code from old Node.cpp to new CAPI version, etc. 2015-04-07 19:31:11 -07:00
