2015-07-02Adding CSubNet constructor over a single CNetAddrJonas Schnelli
2015-07-02use CBanEntry as object container for banned nodesJonas Schnelli
- added a reason enum for a ban - added creation time for a ban Using CBanEntry as container will keep banlist.dat extenable.

Instead of starting Yet Another Thread to dump addresses, use CScheduler to do it.
2015-04-30Use ring buffer of set iterators instead of deque of copies in mrusetPieter Wuille
2015-04-30Replace mruset setAddrKnown with CRollingBloomFilter addrKnownGavin Andresen
Use a probabilistic bloom filter to keep track of which addresses we think we have given our peers, instead of a list. This uses much less memory, at the cost of sometimes failing to relay an address to a peer-- worst case if the bloom filter happens to be as full as it gets, 1-in-1,000. Measured memory usage of a full mruset setAddrKnown: 650Kbytes Constant memory usage of CRollingBloomFilter addrKnown: 37Kbytes. This will also help heap fragmentation, because the 37K of storage is allocated when a CNode is created (when a connection to a peer is established) and then there is no per-item-remembered memory allocation. I plan on testing by restarting a full node with an empty peers.dat, running a while with -debug=addrman and -debug=net, and making sure that the 'addr' message traffic out is reasonable. (suggestions for better tests welcome)

This negates the need for CAddress here at all

No need to define it for every CAddress, as it's memory only anyway.

2015-02-08Sanitize command strings before logging them.Gregory Maxwell
Normally bitcoin core does not display any network originated strings without sanitizing or hex encoding. This wasn't done for strcommand in many places. This could be used to play havoc with a terminal displaying the logs, especially with printtoconsole in use. Thanks to Evil-Knievel for reporting this issue.

This avoids connecting to them again too soon in ThreadOpenConnections. Make an exception for connection failures to the proxy as these shouldn't affect the status of specific nodes.

2014-11-07Do not use third party services for IP detection.Gregory Maxwell
This is a simplified re-do of closed pull #3088. This patch eliminates the privacy and reliability problematic use of centralized web services for discovering the node's addresses for advertisement. The Bitcoin protocol already allows your peers to tell you what IP they think you have, but this data isn't trustworthy since they could lie. So the challenge is using it without creating a DOS vector. To accomplish this we adopt an approach similar to the one used by P2Pool: If we're announcing and don't have a better address discovered (e.g. via UPNP) or configured we just announce to each peer the address that peer told us. Since peers could already replace, forge, or drop our address messages this cannot create a new vulnerability... but if even one of our peers is giving us a good address we'll eventually make a useful advertisement. We also may randomly use the peer-provided address for the daily rebroadcast even if we otherwise have a seemingly routable address, just in case we've been misconfigured (e.g. by UPNP). To avoid privacy problems, we only do these things if discovery is enabled.

2014-10-14Headers-first synchronizationPieter Wuille
Many changes: * Do not use 'getblocks', but 'getheaders', and use it to build a headers tree. * Blocks are fetched in parallel from all available outbound peers, using a limited moving window. When one peer stalls the movement of the window, it is disconnected. * No more orphan blocks. At all. We only ever request a block for which we have verified the headers, and store it to disk immediately. This means that a disk-fill attack would require PoW. * Require protocol version 31800 for every peer (released in december 2010). * No more syncnode (we sync from everyone we can, though limited to 1 during initial *headers* sync). * Introduce some extra named constants, comments and asserts.
