9f550292fe Simply network auth logic and always sent error on auth failure even for unknown networks to prevent forensics. 2016-09-27 13:49:43 -07:00

Adam Ierymenko
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

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

debc4c45ee Set trust established flag in MULTICAST_GATHER. 2016-09-09 11:45:34 -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
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
Adam Ierymenko
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

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
Adam Ierymenko
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
