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

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

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

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.

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
