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

4c455876f9 Revise peer path weighting to always prioritize cluster-optimal paths. 2016-04-19 09:22:51 -07:00

cecfa99b7b (1) cluster members send a flag indicating that a PUSH_DIRECT_PATHS is a cluster redirect, (2) 1.1.5 uses this to avoid a bug (this bug does not exist in 1.1.4) 2016-04-18 16:44:23 -07:00

0c951b6e56 More tweaks to new symmetric NAT buster, and stop using old iterative method since this supersedes it. 2016-02-10 18:41:39 -08:00

740eb6ebc4 Simplify Peer locking to eliminate deadlock with new path recursion check code (and also probably improve performance). 2016-01-12 12:12:25 -08:00

b3e3d4cacc Instead of using binary packet comparison, add a callback to the API to explicitly check whether paths should be used. Check in with this callback (if present) when learning new paths or sending initial packets. 2016-01-11 10:17:44 -08:00

1023ef23b7 Remove somewhat ugly and costly anti-recursion hack -- we will switch to more explicit methods. 2016-01-11 09:06:10 -08:00

47ce52228b Roots should probably not do this since it would likely be a waste of packets. 2016-01-06 12:54:51 -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

0940d673db Always advertise to the cluster when we have a peer even if we have also initiated handoff. This might be the cause of the warmup problem -- will test later. At the very least it should not hurt anything due to pick-latest logic and the fact that cluster members with only suboptimal paths do not respond to WANT_PEER. 2015-11-11 14:36:22 -08:00

32ec378e3b Announce that we have peers on the cluster when we first see them to improve startup times, and add a result crunching script to tests/http. 2015-11-09 18:01:23 -08:00

2cc50bdb10 Try bringing back TTL escalation -- may help with Docker (IP-MASQ) type NAT 2015-11-09 15:44:13 -08:00

35c4e28f31 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. 2015-11-09 14:25:28 -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

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

69857b4ba8 Refactor cluster redirects to move code to push peers out of the actual Cluster function that checks for redirect, and clean up Peer::received() to be a bit more logical. 2015-10-27 09:36:48 -07:00
