15c07c58b6 Refactored network config chunking to sign every chunk to prevent stupid DOS attack potential, and implement network config fast propagate (though we probably will not use this for a bit). 2016-09-27 11:33:48 -07:00

1f74dd4589 Revocation work in progress, add WATCH which is TEE with implicit rate sync (thanks JG@DCVC!), and clean up some cruft in Network. 2016-09-23 16:08:38 -07:00

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

68e549233d Revise bearer token code in controller, and add relay policy as a meta-data item presented to controller by nodes (to facilitate future meshiness). 2016-09-15 13:17:37 -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

8ef0e4bbaf Get rid of HELLO rate gate on path since its basically worthless. There are 65535 ports per IP. 2016-09-13 10:46:36 -07:00

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
Adam Ierymenko
ef87069957 Fix gating of multicast GATHER replies since these can come from upstream, etc., and fix an issue with sending ECHO to recheck marginal paths. 2016-09-09 09:32:00 -07:00

0d4109a9f1 More refactoring to clean up code, and add a gate function to make sure we do not handle OK packets we did not expect. This hardens up a few potential edge cases around security, since such messages might be used to e.g. pollute a cache and DOS under certain conditions. 2016-09-09 08:43:58 -07:00

c9ee8612e4 Credential TTL (tags/capabilities) should be credential time max delta, since we could get pushed one that is newer. 2016-09-07 12:12:52 -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

48a374c82c (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. 2016-09-06 14:05:58 -07:00
Adam Ierymenko
8a2e8bd585 Rework how paths are set as remote cluster preferred. The code is now clearer and cluster preference indications are now very sticky as they should be. 2016-09-06 12:45:28 -07:00
