Implement relay policy, and setting multicast limit to 0 now disables multicast on the network as would be expected.

Get rid of HELLO rate gate on path since its basically worthless. There are 65535 ports per IP.

(1) Public networks now get COMs even though they do not gate with them since they will need them to push auth for multicast stuff, (2) added a bunch of rate limit circuit breakers for anti-DOS, (3) cleanup.

Use ECHO instead of HELLO where possible.

(1) fix crazy bug introduced in doRENDEZVOUS(), (2) reclaim Paths after paths[] condense, (3) fix an edge case around symmetric NAT and external IP change detection.

Dead code removal, and get rid of reliable() because we will no longer make that distinction.

IPv6 links are unfortunately not "reliable." Many IPv6 gateways, while not
...
implementing NAT, do implement stateful firewalling with absurdly short
timeouts (<60s). Keepalives are still required in IPv6.
Network engineers continue to mindlessly carry forward cruft and baggage
from IPv4 to IPv6.

Cleanup in numerous places, reduce network chattiness around MULTICAST_LIKE, and fix a "how was that working" latent bug causing some control traffic to take the scenic route.

Revise peer path weighting to always prioritize cluster-optimal paths.

Temporarily blacklist he.net IPv6 tunnel addresses for paths: these usually have a very low MTU which causes packet loss and other issues.

Make activity no longer a function of ping frequency, since this causes compatibility bugs when the latter was modified due to timer interactions with other versions.

Tighten up dead path detection. Should now auto-detect dead paths in less than 10 seconds at a very small cost in ECHO requests (or HELLOs for older peers). GitHib issue #272
2016-01-06 10:00:03 -08:00

Mark geo-redirected paths as suboptimal and do not report that we have a peer if all we have is one of these. Also a few other small fixes.

Eliminate some more dead code. We may do path trust, but not like that.

Some cleanup, and use getPeerNoCache() exclusively in Cluster.

Factor out RemotePath subclass of Path -- no longer needed, just cruft.

(1) Make ZT_ naming convention consistent (get rid of ZT1_), (2) Make local interface a full sockaddr_storage instead of an int identifier, which turns out to be better for multi-homing and other uses.
2015-09-24 16:21:36 -07:00

A bunch of comments and cleanup, including some to yesterday's direct path pushing changes. Move path viability check to one place, and stop trying to use link-local addresses since they are not reliable.

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

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.

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.

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.
