Adam Ierymenko	52c3b7c34e	Implemented empirical determination of external addressing, paritioned per scope.	2015-04-07 11:56:10 -07:00
Adam Ierymenko	817824b88b	Some external surface awareness work, and IP scope classification.	2015-04-07 10:57:59 -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	2416491cbc	Permanently retire peers.persist, but make iddb.d always enabled instead since identities are what we really want to cache.	2014-10-13 14:12:51 -07:00
Adam Ierymenko	6316011024	Make crypto and compression build optimized in debug, and also try disabling peers.persist -- might ship this way as it seems more trouble than its worth.	2014-10-12 11:42:49 -07:00

Adam Ierymenko	e1882b614b	Some cleanup, Multicaster now sends multicasts as it gets additional members.	2014-10-01 14:05:25 -07:00
Adam Ierymenko	81b12b6826	Rename the ubiquitous _r pointer to RuntimeEnvironment to RR just to be a little more consistent about using _ to denote private member variables.	2014-09-24 13:53:03 -07:00
Adam Ierymenko	282114e96c	Makefile changes, and make Topology::getBestSupernode() return the "next" supernode if I am a supernode. Also some comment cleanup.	2014-08-19 10:09:21 -07:00

Adam Ierymenko	c2187c8759	(1) distribute default root-topology in new dictionary format, (2) bump peer serialization version to force obsolescence of old supernodes, (3) stop outputting a log message every time we poll for software updates	2014-08-14 19:52:22 -04:00
Adam Ierymenko	be6b61b1bc	Accept supernode dictionaries in Topology, also fix (unused) field name in one of these.	2014-08-14 18:06:18 -04:00
Adam Ierymenko	88bdb81791	Keep track of basic aliveness for peers regardless if direct or indirect connectivity and use this for multicast propagation. Also consolidate adding of active bridges via the same functor as regular multicast next hops.	2014-06-30 11:31:04 -07:00
Adam Ierymenko	7831c4bfef	Cleanup, dead code removal, some pretty insignificant security stuff that's based on recommendations.	2014-04-18 00:14:12 -07:00
Adam Ierymenko	f13493edb2	Oops... turns out we need to differentiate incoming from outgoing TCP and indeed learn incoming TCP paths. Otherwise the recipient of a TCP connection does not know to reply via TCP! Heh.	2014-03-31 22:23:55 -07:00
Adam Ierymenko	8e587ae481	Clean dead paths from peers.	2014-03-31 11:41:14 -07:00

Adam Ierymenko	8d3eb1a258	A few renamings to be consistent.	2014-03-21 14:18:35 -07:00

Adam Ierymenko	d04e5a1fe0	Add a simple but very nice mechanism for avoiding potentially dead supernodes.	2014-02-03 11:09:09 -08:00
Adam Ierymenko	22efa1ab53	Windows Installer work, fix 100% CPU bug in EthernetTap on Windows, Windows lockDownFile() implementation that uses 'cacls' utility.	2014-01-26 10:21:43 -08:00
Adam Ierymenko	5e71e07f59	Add persistent identity caching for use on supernodes. Activate by just making an iddb.d directory in the ZeroTier home folder. Also clean up some obsolete cruft from makefiles.	2013-10-21 14:12:00 -04:00
Adam Ierymenko	40e4f39181	Peers are now dumped on shutdown in a persistence cache and reloaded on startup, which is good enough for clients right now. Supernodes will get something else for long-term authoritative identity caching.	2013-10-21 11:15:47 -04:00
Adam Ierymenko	6e217dfcb0	Get rid of DBM, which technically is a case of YAGNI. Supernodes will need a way to save identities, but that can be a different feature. Regular clients do not really need a permanent cache (yet). When/if we do need one we can do it then. Until then it only caused problems.	2013-10-21 10:29:44 -04:00
Adam Ierymenko	ca93b4a1ac	Clean up some stuff, including a few spots where exceptions were not being handled correctly.	2013-10-18 14:16:53 -04:00
