Adam Ierymenko	2160164e8c	(1) Get rid of path sorting and just scan them, since sorting may have been a premature optimization that introduced a regression and path instability in a few edge cases, and (2) do not attempt to contact remote paths received via PUSH_DIRECT_PATH if we already have that path and it is already active (dumb, should have done this originally)	2015-12-17 10:53:07 -08:00
Adam Ierymenko	82aa3f59d6	Fix bug in ECHO handling (OK was invalid!), and use ECHO on newer peers for path confirmation. Also get rid of path confirmation circuit breaker since this causes issues with some peers and should be done more intelligently anyway.	2015-12-15 10:30:40 -08:00
Adam Ierymenko	ceaef19fb7	Fix for GitHub issue #260 -- fix for (non-exploitable) crash in network preferred relay code	2015-11-30 17:20:12 -08:00
Adam Ierymenko	2cc50bdb10	Try bringing back TTL escalation -- may help with Docker (IP-MASQ) type NAT	2015-11-09 15:44:13 -08:00
Adam Ierymenko	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
Adam Ierymenko	5f39d5b7ea	Further pare down Cluster messaging and rename some stuff.	2015-11-06 14:37:17 -08:00

Adam Ierymenko	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	16bc3e0398	Factor out RemotePath subclass of Path -- no longer needed, just cruft.	2015-10-27 15:00:16 -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
Adam Ierymenko	cc4d0199e7	Fix vProto init.	2015-10-16 10:58:59 -07:00

Adam Ierymenko	64bf3ffe6c	Mutex cleanup.	2015-10-01 11:44:09 -07:00
Adam Ierymenko	a3db7d0728	Refactor: move network COMs out of Network and into Peer in prep for tightening up multicast lookup and other things.	2015-10-01 11:11:52 -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
Adam Ierymenko	367ffde00c	Plumb through localInterfaceId to track local interfaces corresponding with remote addresses.	2015-09-23 13:49:56 -07:00

Adam Ierymenko	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	93bb934d4e	Some cleanup, docs, and Path -> Path > RemotePath refactor.	2015-07-06 14:08:13 -07:00
Adam Ierymenko	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	1213073916	Apple auto-update stuff, now for Windows.	2015-05-20 19:38:49 -07:00

Adam Ierymenko	98bcc3d4b5	Disable a few noisy TRACEs, and limit how often we confirm new paths to avoid flooding.	2015-04-15 13:15:09 -07:00
Adam Ierymenko	5e331d6733	Restrict unite() to desperation==0 since NAT-t only works right now with direct links.	2015-04-10 10:13:50 -07:00
Adam Ierymenko	ccc73b920e	Node peer list function for CAPI, and some Peer cleanup.	2015-04-08 18:45:21 -07:00

Adam Ierymenko	0a90681849	Add ping(), and a logic fix in SelfAwareness.	2015-04-07 12:32:05 -07:00
Adam Ierymenko	24608d5ca3	Always use HELLO to contact, and we now confirm newly learned paths via a two-way handshake to prevent half-connects.	2015-04-07 12:22:33 -07:00
Adam Ierymenko	52c3b7c34e	Implemented empirical determination of external addressing, paritioned per scope.	2015-04-07 11:56:10 -07:00

Adam Ierymenko	ee0f56355b	Send path simplification.	2015-04-03 13:14:37 -07:00
Adam Ierymenko	a69e1876f1	The concept of link desperation (escalating to less desirable transports) simplifies a ton of stuff. Loads of spaghetti logic can die since we no longer have to make these decisions down in the core.	2015-04-02 17:54:56 -07:00
Adam Ierymenko	7ff0cab1b7	docs	2015-03-31 18:33:39 -07:00
Adam Ierymenko	93012b0ee5	Re-incorporation: ZeroTier Networks -> ZeroTier, Inc. [Delaware]	2015-02-17 13:11:34 -08:00
Adam Ierymenko	0b84c10ccc	Add confirmation step to new netconf, with the caveat that it will be disabled for older netconf servers to avoid race. Also add some comments.	2015-01-09 16:35:20 -05:00
