* net: Automatically create hidden service, listen on TorWladimir J. van der Laan2015-11-101-4/+1
| | | | | | | | | | | | | | | | | | | | 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.
* Set TCP_NODELAY on P2P sockets.Gregory Maxwell2015-10-221-1/+8
| | | | | | | | 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.

* Fix two problems in CSubNet parsingWladimir J. van der Laan2015-05-261-1/+5
| | | | | | | | | | | | | | | 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 code for CSubnetWladimir J. van der Laan2015-05-261-8/+6
| | | | | Simplify the code by using CAddress.ip directly, instead of the reversed GetByte() semantics.

* privacy: Stream isolation for TorWladimir J. van der Laan2015-04-171-66/+104
| | | | | | | | | | | | | 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

* Regard connection failures as attempt for addrmanWladimir J. van der Laan2014-12-021-4/+16
| | | | | | | 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.

* netbase: Make SOCKS5 negotiation interruptibleWladimir J. van der Laan2014-09-101-18/+70
| | | | | | | | | | | | 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.
* netbase: Use .data() instead of .c_str() on binary stringWladimir J. van der Laan2014-09-081-1/+1
| | | | | `.c_str()` is only guaranteed to return the data up to the first NUL character.
* Split up util.cpp/hWladimir J. van der Laan2014-08-261-0/+2
| | | | | | | | | | | | | | | | 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.

* Convert closesocket 'compat wrapper' to function in netbaseWladimir J. van der Laan2014-07-171-20/+33
| | | | | | | | | | | 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.

* | Use async name resolving to improve net thread responsivenessHuang Le2014-06-271-1/+59
| | | | | | | | | | | | | | | | | | | | | | | | In the LookupIntern(), things changed are: 1. Call getaddrinfo_a() instead of getaddrinfo() if available, the former is a sync version of the latter; 2. Try using inet_pton()/inet_addr() to convert the input text to a network addr structure at first, if success the extra name resolving thread inside getaddrinfo_a() could be avoided; 3. An interruption point added in the waiting loop for return from getaddrinfo_a(), which completes the improve for thread responsiveness. A easy way to see the effect is to kick off a 'bitcoind stop' immediately after 'bitcoind -daemon', before the change it would take several, or even tens of, minutes on a bad network situation to wait for the running bitcoind to exit, now it costs only seconds.

* Remove build-time no-IPv6 settingWladimir J. van der Laan2014-05-011-26/+0
| | | | | | | | | | | The year is 2014. All supported operating systems have IPv6 support, most certainly at build time (this doesn't mean that IPv6 is configured, of course). If noone is exercising the functionality to disable it, that means it doesn't get tested, and IMO it's better to get rid of it. (it's also not used consistently in RPC/boost and Net code...)
