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

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

ea1da3321a Rate gate requests for COM. 2016-09-12 15:19:21 -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

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

c7a4da3dd3 Turns out we do not need to pass network to receive(). 2016-09-07 15:24:53 -07:00

a7d988745b Use ECHO instead of HELLO where possible. 2016-09-07 12:01:03 -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

f2d2df2b11 Cluster build fix. 2016-09-06 15:06:07 -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
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

584228b2b5 Dead code removal, and get rid of reliable() because we will no longer make that distinction. 2016-08-24 17:56:35 -07:00

c476285bd6 Harden PUSH_DIRECT_PATHS and simplify things by only doing it on receive when hops>0 and trust has been established. 2016-08-24 16:16:39 -07:00

e1310a764a More cleanup and removal of cruft due to obsolete network-specific relays (will be replaced with federation stuff). 2016-08-09 15:45:26 -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
Adam Ierymenko
4c455876f9 Revise peer path weighting to always prioritize cluster-optimal paths. 2016-04-19 09:22:51 -07:00
Adam Ierymenko
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

284e5d83b5 Fix some broken TRACEs and a tiny reorder in a few ifs. 2016-03-28 12:15:24 -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
Adam Ierymenko
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
