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

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

1cfa67bbdd Bunch more control plane work, and shelve old UI -- React FTW. 2015-04-14 13:56:28 -07:00

9e651b39e4 Add some TRACE around pinging (for now), and refactor service/One to just run in the foreground as some platforms may not require threads at all. 2015-04-10 11:40:45 -07:00

5e331d6733 Restrict unite() to desperation==0 since NAT-t only works right now with direct links. 2015-04-10 10:13:50 -07:00

40bfe37a19 Use max of core or most recent path desperation for pings. 2015-04-08 14:58:23 -07:00

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

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

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

ee9e6a3c6b Change path selection logic to exclude non-fixed and non-active paths -- possible fix for "NAT traversal coma" issue. Also fix a typo. 2014-11-20 13:20:16 -08:00

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

0d017c043f Stop persisting last announcement time since Multicaster is volatile. Also some more legacy multicast fixes. 2014-10-11 16:26:02 -07:00

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

4e9280fc7a Rip out dead "firewall opener" code, replace in pipeline with anti-symmetric-NAT tactics. 2014-09-05 16:23:24 -07:00
Adam Ierymenko
8a804b5257 (1) Disable firewall openers (its easy to re-enable), (2) Do some prep work for making supernode topology hot-updatable. 2014-08-05 14:05:50 -07:00

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

b117ff5435 Probable fix for GitHub issue #63 - do not unite() if either path is TCP, since doing so can result in asymmetric failed NAT-t over UDP if one side has a firewall that permits outgoing UDP but not incoming. 2014-04-10 11:17:54 -07:00

73153b89b4 Some cleanup, and use best (not first) UDP addresses for NAT-t VERB_RENDEZVOUS computation. 2014-04-09 16:00:25 -07:00

fe85426df6 A few more tweaks to TCP failover... seems to be switching back and forth pretty well now! 2014-04-03 17:12:34 -07:00

700a450806 More tweaks to algorithm for determining when to fail over to TCP, and stop supernodes from resynchronizing unless explicitly ordered. 2014-04-01 18:39:10 -07:00
Adam Ierymenko
0e1fc06a6f The remove paths on send fail thing in Peer.cpp was not well thought out, and there is no point in mallocing the TCP write buffer. 2014-04-01 15:55:05 -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
