* Sanitize command strings before logging them.Gregory Maxwell2015-02-081-1/+1
| | | | | | | | | | 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.

* Do not use third party services for IP detection.Gregory Maxwell2014-11-071-125/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Headers-first synchronizationPieter Wuille2014-10-141-50/+0
| | | | | | | | | | | | | | | 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.

| * | netbase: Make SOCKS5 negotiation interruptibleWladimir J. van der Laan2014-09-101-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoids that SOCKS5 negotiation will hold up the shutdown process. - Sockets can stay in non-blocking mode, no need to switch it on/off anymore - Adds a timeout (20 seconds) on SOCK5 negotiation. This should be enough for even Tor to get a connection to a hidden service, and avoids blocking the opencon thread indefinitely on a hanging proxy. Fixes #2954.

* Split up util.cpp/hWladimir J. van der Laan2014-08-261-0/+1
| | | | | | | | | | | | | | | | 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.
