3587aa1ea7 Add and send certificates of representation to tell people what our valid upstreams are. These are not used yet but will be needed for future privacy modes, etc. Also some cleanup. 2017-02-04 13:17:00 -08:00

d3524f3609 Refactor COM stuff a bit, and respond to COM requests a bit more readily for rapid setup. Will need to revisit later. 2016-09-20 21:21:34 -07:00

5b6d27e659 Implement relay policy, and setting multicast limit to 0 now disables multicast on the network as would be expected. 2016-09-13 14:27:18 -07:00

cba37c6107 Add a few more rate limit gates for anti-DOS hardening. 2016-09-13 10:13:23 -07:00
Adam Ierymenko
ab9afbc749 (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. 2016-09-09 11:36:10 -07:00

1908aa55f5 Refactor MULTICAST_LIKE pushing to eliminate redundant and unnecessary pushes and simplify code. 2016-09-07 15:15:52 -07:00

b5c86b6ba4 Bunch more path refactoring. Peers no longer forget paths, but do not normally use expired paths. Expired paths might still be tried if nothing else is reachable. 2016-09-07 11:13:17 -07:00

2f18a92e20 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. 2016-04-19 12:09:35 -07:00

56096be8b6 Tweak new RX queue algorithm to "expire" old entries to prevent always needing to traverse the whole queue array. 2016-04-06 16:28:40 -07:00

4a109658ab More refactoring and prep for explicit interface bindings (for default route support). 2016-04-05 11:59:46 -07:00

d6a1868d0a Refactor incoming packet (rxQueue/fragmentQueue) to eliminate variable length queues and merge queues. This is both faster and saves memory. 2016-03-18 14:16:07 -07:00

2aa7138373 Reduce direct ping delay back to 1m and make SelfAwareness aware of local received-on address to eliminate false symmetric classification. 2016-02-22 09:47:50 -08:00
Adam Ierymenko
63ec7e58d4 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. 2016-02-08 10:03:01 -08:00

05b2c0743f 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

d8143a5e18 Implement first pass on rapid dead path detection, and increment version to 1.1.3 (dev) 2016-01-05 16:41:54 -08:00

e6808c69f8 Increase maximum number of paths per IP scope to 4
Otherwise, local discovered routes are ignored.
Don't know what the best value would be. Taking 4 for now.

b94335f115 Increase WHOIS retry delay slightly to allow for global cluster latency (e.g. 300+ms from New York to Johhannesburg) 2015-11-11 11:07:08 -08:00

cc1b275ad9 Replicate peer endpoints and forget paths if we have them -- this allows two clusters to talk to each other, whereas forgetting all paths does not. 2015-10-27 16:47:13 -07:00
Adam Ierymenko
a1a0ee4edb Fix infinite loop in Cluster, clean up some stuff elsewhere, and back out rate limiting in PUSH_DIRECT_PATHS for now (but we will do something else to mitigate amplification attacks) 2015-10-27 12:01:00 -07:00
Adam Ierymenko
62db18b6dd Lessen this limit just a bit to make cluster settle faster. 2015-10-27 11:01:58 -07:00

7d62dbe9f7 Tune NAT-t keepalives so that timing is better obeyed, clean up a build warning, and fix a potential source of network recursion (though harmless). 2015-10-07 11:57:59 -07:00

a3db7d0728 Refactor: move network COMs out of Network and into Peer in prep for tightening up multicast lookup and other things. 2015-10-01 11:11:52 -07:00
Adam Ierymenko
f69454ec98 (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
