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

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.

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

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

d647a587a1 (1) Fix updating of network revision counter on member change.
(2) Go back to timestamp as certificate revision number. This is simpler
    and more robust than using the network revision number for this and
    forcing network revision fast-forward, which could cause some peers
    to fall off the horizon when you don't want them to.

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

8130848020 More refactoring... and update the API a bit... turns out my strategy for reducing indirect function calls also increased memcpy()s which are more expensive. This is simpler and faster. 2015-04-01 14:59:44 -07:00

Adam Ierymenko
03dc823ad7 (1) Back off a little on default max multicast limit since 128 is pretty bandwidth heavy, (2) add a little to default multicast rate limit since new MC algo is fairerererer, (3) decided not to involve netconf masters in multicast so take that out of list of who gets LIKEs. 2014-10-10 12:55:06 -07:00

f8d4611d15 (1) Tweak LAN locator beacon frequencies, (2) Windows virtual networks
now show up as *real* networks and prompt the user to set their
location and firewall status (public, private, home/work, etc.).

The hack used to achieve #2 should not be examined by children or those
suffering from epilepsy or heart conditions.

595b386afc Increase maximum packet fragments to make room for huge multicasts with certificates of membership tagged onto them. This likely will not actually increase the number of fragments in practice much, since these are then subsequently compressed. But the buffer needs to be allocated with room for them, otherwise these packets get dropped with a range_error exception internally. 2014-03-31 14:53:33 -07:00
