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

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

8fb442d81a Yet more cleanup to TCP logic, this time adding a master switch and adding UDP preference in send(). 2014-04-09 17:08:35 -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

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

9f28eec95c VERSION 0.6.7: revert change for GitHub issue #20
This will have to be thought out more. The old version worked fine 99% of the
time so we'll revisit this.

cc2a1444ae TRACE output improvements and compile fix. 2013-12-31 11:18:40 -08:00
Adam Ierymenko
10df5dcf70 Fix several things:
(1) The changes to path learning in the two previous releases were poorly thought out,
and this version should remedy that by introducing PROBE. This is basically a kind of
ECHO request and is used to authenticate endpoints that are not learned via a valid
request/response pair. Thus we will still passively learn endpoints, but securely.

(2) Turns out there was a security oversight in _doHELLO() that could have permitted...
well... I'm not sure it was exploitable to do anything particularly interesting since
a bad identity would be discarded anyway, but fix it just the same.

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

3443b203e4 Each peer now tracks the last time it announced multicast LIKEs independently and does so frequently enough to prevent expires. Also add a multicast debug facility for use on the testnet. 2013-10-01 16:01:36 -04:00
