Also fix up a few small issues: - Lookup with "badip:port" now sets the port to 0 - Don't allow assert to have side-effects

2016-05-09SOCKS5 connecting and connected messages with -debug=net.Warren Togami
They were too noisy and not necessary for normal operation.
2016-05-09Make failures to connect via Socks5() more informative and less ↵Warren Togami
unnecessarily scary. * The "ERROR" was printed far too often during normal operation for what was not an error. * Makes the Socks5() connect failure similar to the IP connect failure in debug.log. Before: `2016-05-09 00:15:00 ERROR: Proxy error: host unreachable` After: `2016-05-09 00:15:00 Socks5() connect to t6xj6wilh4ytvcs7.onion:18333 failed: host unreachable"`
2016-04-20net: disable resolving from storage structuresCory Fields
CNetAddr/CService/CSubnet can no longer resolve DNS.
2016-04-20net: resolve outside of storage structuresCory Fields
Rather than allowing CNetAddr/CService/CSubNet to launch DNS queries, require that addresses are already resolved. This greatly simplifies async resolve logic, and makes it harder to accidentally leak DNS queries.

2015-11-10net: Automatically create hidden service, listen on TorWladimir J. van der Laan
Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket API, to create and destroy 'ephemeral' hidden services programmatically. https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service This means that if Tor is running (and proper authorization is available), bitcoin automatically creates a hidden service to listen on, without user manual configuration. This will positively affect the number of available .onion nodes. - When the node is started, connect to Tor through control socket - Send `ADD_ONION` command - First time: - Make it create a hidden service key - Save the key in the data directory for later usage - Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on). - Keep control socket connection open for as long node is running. The hidden service will (by default) automatically go away when the connection is closed.
2015-10-22Set TCP_NODELAY on P2P sockets.Gregory Maxwell
Nagle appears to be a significant contributor to latency now that the static sleeps are gone. Most of our messages are relatively large compared to IP + TCP so I do not expect this to create enormous overhead. This may also reduce traffic burstyness somewhat.
2015-09-16net: Fix CIDR notation in ToString()Wladimir J. van der Laan
Only use CIDR notation if the netmask can be represented as such.

2015-05-26Fix two problems in CSubNet parsingWladimir J. van der Laan
Fix two CSubNet constructor problems: - The use of `/x` where 8 does not divide x was broken, due to a bit-order issue - The use of e.g. `1.2.3.4/24` where the netmasked bits in the network are not 0 was broken. Fix this by explicitly normalizing the netwok according to the bitmask. Also add tests for these cases. Fixes #6179. Thanks to @jonasschnelli for reporting and initial fix.

Simplify the code by using CAddress.ip directly, instead of the reversed GetByte() semantics.

2015-04-17privacy: Stream isolation for TorWladimir J. van der Laan
According to Tor's extensions to the SOCKS protocol (https://gitweb.torproject.org/torspec.git/tree/socks-extensions.txt) it is possible to perform stream isolation by providing authentication to the proxy. Each set of credentials will create a new circuit, which makes it harder to correlate connections. This patch adds an option, `-proxyrandomize` (on by default) that randomizes credentials for every outgoing connection, thus creating a new circuit. 2015-03-16 15:29:59 SOCKS5 Sending proxy authentication 3842137544:3256031132

2014-12-02Regard connection failures as attempt for addrmanWladimir J. van der Laan
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.

2014-09-10netbase: Make SOCKS5 negotiation interruptibleWladimir J. van der Laan
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.
2014-09-08netbase: Use .data() instead of .c_str() on binary stringWladimir J. van der Laan
`.c_str()` is only guaranteed to return the data up to the first NUL character.
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.

2014-07-17Convert closesocket 'compat wrapper' to function in netbaseWladimir J. van der Laan
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.
