57c7992c78 GitHub issue #191 - kill intra-network multicast rate limits (which were not well supported or easily configurable anyway) -- this is really left over from the old collaborative multicast propagation algorithm. New algorithm (in for a while) has been sender-side replication in which sender "pays" all bandwidth, which intrinsically limits multicast. 2015-06-26 12:36:45 -07:00

Adam Ierymenko
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

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

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
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

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

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

f80ec871f6 Make EthernetTap creation occur in a background thread in Network since it's a time consuming operation on Windows. This fixes one of the last remaining Windows problems. 2014-01-27 23:13:36 -08:00
Adam Ierymenko
370dd6c4da Several things:
(1) Add a bunch of tedious type casts to eliminate unnecessary compiler warnings on Windows X64 builds.

(2) Some EthernetTap work to integrate Windows custom IOCTL for multicast group lookup (not done quite yet).

(3) Dump some more info in selftest to make sure our Windows path lookup functions are returning sane results.
2014-01-21 13:07:22 -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.

ef08494237 Send HELLO instead of NOP for NAT-t in order to measure latency always. Also prevents a race that can cause the first NAT-t to fail where the NOP arrives before the WHOIS reply from the supernode. Now NAT-t initiators will push their own public keys anyway so that doesnt matter. 2013-07-06 16:20:35 -04:00
