This sets aside a number of connection slots for whitelisted peers, useful for ensuring your local users and miners can always get in, even if your limit on inbound connections has already been reached.

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)

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.

2014-08-26Split up util.cpp/hWladimir J. van der Laan
Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.

Simpler alternative to #4348. The current setup with closesocket() is strange. It poses as a compatibility wrapper but adds functionality. Rename it and make it a documented utility function in netbase. Code movement only, zero effect on the functionality.

2014-07-09Introduce whitelisted peers.Pieter Wuille
This adds a -whitelist option to specify subnet ranges from which peers that connect are whitelisted. In addition, there is a -whitebind option which works like -bind, except peers connecting to it are also whitelisted (allowing a separate listen port for trusted connections). Being whitelisted has two effects (for now): * They are immune to DoS disconnection/banning. * Transactions they broadcast (which are valid) are always relayed, even if they were already in the mempool. This means that a node can function as a gateway for a local network, and that rebroadcasts from the local network will work as expected. Whitelisting replaces the magic exemption localhost had for DoS disconnection (local addresses are still never banned, though), which implied hidden service connects (from a localhost Tor node) were incorrectly immune to DoS disconnection as well. This old behaviour is removed for that reason, but can be restored using -whitelist=127.0.0.1 or -whitelist=::1 can be specified. -whitebind is safer to use in case non-trusted localhost connections are expected (like hidden services).
