1d36ea8ddf 0.3.0: BREAKS PROTOCOL BACKWARD COMPATIBILITY
This version is not compatible with versions prior to 0.3.0, so
'git pull' and restart if you are following the alpha.

Changes from 0.2.5:

 - All multicast frames are now signed by the original sender. This
   will permit very efficient and fault tolerant rate limitation
   across networks, and imposes a kind of "hash cash" cost on those
   who wish to flood the network by forcing them to keep regenerating
   new identities.

 - Simplified peer last unicast / last multicast accounting.

 - Improvements to multicast propagation algorithm to achieve better
   coverage with less redundant messages.

 - The bloated Switch class went on a diet, having packet decoding
   broken out into PacketDecoder and multicast propagation algorithm
   broken out into Multicaster.

 - Multicaster is implemented as a template mockable class to permit
   future simulations of huge scale multicast using the actual code
   instead of mockups in another language.

 - Introduced a faster non-cryptographic random source for things
   like multicast propagation and address choosing.

 - Some code cleanup, removal of outdated comments, etc.

ca83f07b54 Simpler variant on multicast propagation algorithm seems to perform better by being less deterministic. May also be faster. 2013-07-13 15:17:21 -04:00

ef3e319c64 Several things:
(1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed.

(2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture.

(3) Add -fstack-protect to Makefile to bounds check stack variables.

Adam Ierymenko
ef08494237 Send HELLO instead of NOP for NAT-t in order to measure latency always. Also prevents a race that can cause the first NAT-t to fail where the NOP arrives before the WHOIS reply from the supernode. Now NAT-t initiators will push their own public keys anyway so that doesnt matter. 2013-07-06 16:20:35 -04:00

2c0cdc9484 Fix for failure to bind port if IPv6 is not enabled on a system -- it should succeed if it can bind either V4 or V6 or both and only fail if neither binds 2013-07-06 13:43:24 -04:00
Adam Ierymenko
cfef114c31 Possible fix for issue #4 - segfault in ___removeIp helper function in EthernetTap on OSX -- I think the problem may have been that I was using set::erase(key) while also using an iterator, so now it uses erase(iterator). See if it happens again, cause I could not duplicate the issue. Possible minor difference in STL version. 2013-07-06 13:34:35 -04:00
