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

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

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

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.

2f00ae4fd7 Version 0.6.1: minor bug fix, DBM removal
This version removes the peer DBM present in earlier releases. It is not necessary for
regular clients and has been a source of problems.

There is a long-term identity cache that can be enabled by making a directory called
"iddb.d" in the home folder and restarting ZT1. This is probably something only our
supernodes would need, since regular nodes can easily WHOIS peers they've forgotten
about.

On shutdown, the peer database is dumped to disk. It's then restored on startup.
Peers that have not been used in a while are cleaned out, so this keeps this data
set small.

A DBM may re-appear later if it's needed, but for now it was YAGNI.
