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

be4683a96d Get rid of random port strategy -- research does not support. 2015-04-06 15:03:08 -07:00

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

4e95384ad6 Cleanup, add tristate to config code in Network, and happy new year! 2015-01-05 17:47:59 -08:00

0c85b4ef5f Tweak to symmetric NAT buster to add one to the number of ports above the current one it attempts. 2014-11-20 13:42:18 -08:00

5bb854e504 Fix a nasty bug introduced in packet fragmentation a while back during refactoring, and a few other things related to multicast. 2014-10-28 17:25:34 -07:00
Adam Ierymenko
4941c8a1f3 New multicast bug fixes, TRACE improvements, and temporarily disable legacy multicast for debugging purposes. 2014-10-09 17:58:31 -07:00

d5e0f7e3e4 Reorg multicast packet, and a whole bunch of refactoring around the pushing of certificates of membership. 2014-10-09 12:42:25 -07:00

2c8321be1f Pull logic to always send new multicasts to supernode since we need to do that differently, re-add support for active bridges, and remove some gratuitous use of std::set where not needed. 2014-10-04 13:15:02 -07:00
Adam Ierymenko
e7c81ef34e Turns out that needed to be a list after all. Also clean up Multicaster::gather(). 2014-10-03 22:03:19 -07:00
Adam Ierymenko
49dc47ff38 Make multicast gathering a bit smarter. 2014-10-02 11:35:37 -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
ae082c3cb8 Yay... now everything compiles! Getting close to testing on this. Still have not added backward compatibility support for relaying of multicasts to 0.9.X clients yet but that will be easy. Will test with heterogenous 1.0.0 clients only first. 2014-10-01 12:41:48 -07:00

8607aa7c3c Everything in for new multicast except IncomingPacket parsing... 2014-09-30 08:38:03 -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

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
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
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
Adam Ierymenko
458f6ae7c3 Only add active bridges to top of MC propagation list if they are alive. Otherwise a dead active bridge might kill multicast for us. 2014-06-26 18:13:48 -07:00

6802da457e Bridging pretty much ready to test! Got Switch all wired up. Also fix a latent probably-never-triggered bug in MULTICAST_FRAME handling. GitHub issue #68 2014-06-13 21:06:34 -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

316e8d1939 Build fix. 2014-03-31 22:30:08 -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
