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	9490b1f136	Try prioritizing cluster-send over direct send in cluster mode -- may improve cluster relaying reliability.	2015-11-06 13:38:56 -08:00
Adam Ierymenko	8ef4edebbf	Deferred decode for HELLO to prevent HELLOcalypse under high load of new peers.	2015-11-05 12:22:58 -08:00
Adam Ierymenko	c9e6e60c09	Handle ZeroTier-RFC4193 IPv6 address NDP queries inline by spoofing responses if the addressing scheme matches -- this allows multicast-free instant lookup of local IPv6 for better performance and reliability.	2015-11-03 10:46:41 -08:00
Adam Ierymenko	4e9d430476	Make root and relay selection somewhat more robust.	2015-11-02 16:03:28 -08:00

Adam Ierymenko	f692cec763	Change how cluster relays packets -- just PROXY_UNITE and then send packet via normal ZeroTier front plane -- more efficient and eliminates fragmentation issues.	2015-10-27 14:04:12 -07:00
Adam Ierymenko	de761c5a82	Fix test world def.	2015-10-26 15:47:32 -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	85b90f122a	Final std::map<> from Switch, and add some smallish default values for hash size.	2015-09-04 15:35:43 -07:00
Adam Ierymenko	3dba016a93	Almost done... very few std::map<>s remaining in any spot that matters.	2015-09-04 15:21:22 -07:00
Adam Ierymenko	db0369e9b8	Remove way-overkill multimap from Switch.	2015-09-04 14:56:39 -07:00
Adam Ierymenko	0ab3e49be9	Starting in on Switch... kill map in defrag queue, which will probably improve performance pretty decently under high load with lots of peers.	2015-09-04 14:44:22 -07:00

Adam Ierymenko	fe20f0d7cd	Put back legacy code to listen for LAN announcements to support same network location with pre-1.0.4 clients.	2015-07-13 08:33:02 -07:00
Adam Ierymenko	3f567a07ca	Save a little bit of RAM by getting rid of overkill CMWC4096 non-crypto PRNG and replacing it with a simple non-crypto PRNG that just uses Salsa20.	2015-07-07 10:49:50 -07:00
Adam Ierymenko	41fc08b330	etherTypeName() is only used in Switch and only with ZT_TRACE	2015-07-07 10:06:05 -07:00

Adam Ierymenko	e5f7c55c54	Documentation in Packet, more work on path push, and clean up ancient legacy support code in Switch.	2015-07-06 12:34:35 -07:00
Adam Ierymenko	57c7992c78	GitHub issue #191 - kill intra-network multicast rate limits (which were not well supported or easily configurable anyway) -- this is really left over from the old collaborative multicast propagation algorithm. New algorithm (in for a while) has been sender-side replication in which sender "pays" all bandwidth, which intrinsically limits multicast.	2015-06-26 12:36:45 -07:00
Adam Ierymenko	7bae95836c	Root server terminology cleanup, and tighten up a security check by checking full identity of peers instead of just address.	2015-06-19 10:23:25 -07:00

Adam Ierymenko	960ceb4791	Rest of GitHub issue #140 implementation.	2015-06-01 17:50:44 -07:00
