Our approach is to specify a means to add pluggable + transport implementations to Tor clients and bridges so that they can + negotiate a superencipherment for the Tor protocol. + +Specifications: Client behavior + + We extend the bridge line format to allow you to say which method + to use to connect to a bridge. + + The new format is: + Bridge method address:port [[keyid=]id-fingerprint] [k=v] [k=v] [k=v] + + To connect to such a bridge, the Tor program needs to know which + SOCKS proxy will support the transport called "method". It + then connects to this proxy, and asks it to connect to + address:port. If [id-fingerprint] is provided, Tor should expect + the public identity key on the TLS connection to match the digest + provided in [id-fingerprint]. If any [k=v] items are provided, + they are configuration parameters for the proxy: Tor should + separate them with semicolons and put them in the user and + password fields of the request, splitting them across the fields + as necessary. If a key or value value must contain a semicolon or + a backslash, it is escaped with a backslash. + + Method names must be C identifiers. + + For reference, the old bridge format was + Bridge address[:port] [id-fingerprint] + where port defaults to 443 and the id-fingerprint is optional. The + new format can be distinguished from the old one by checking if the + first argument has any non-C-identifier characters. (Looking for a + period should be a simple way.) Also, while the id-fingerprint could + optionally include whitespace in the old format, whitespace in the + id-fingerprint is not permitted in the new format. + + Example: if the bridge line is "bridge trebuchet www.example.com:3333 + keyid=09F911029D74E35BD84156C5635688C009F909F9 rocks=20 height=5.6m" + AND if the Tor client knows that the 'trebuchet' method is supported, + the client should connect to the proxy that provides the 'trebuchet' + method, ask it to connect to www.example.com, and provide the string + "rocks=20;height=5.6m" as the username, the password, or split + across the username and password. + + There are two ways to tell Tor clients about protocol proxies: + external proxies and managed proxies. An external proxy is configured + with + ClientTransportPlugin <method> socks4 <address:port> [auth=X] + or + ClientTransportPlugin <method> socks5 <address:port> [username=X] [password=Y] + as in + "ClientTransportPlugin trebuchet socks5 127.0.0.1:9999". + This example tells Tor that another program is already running to handle + 'trubuchet' connections, and Tor doesn't need to worry about it. + + A managed proxy is configured with + ClientTransportPlugin <methods> exec <path> [options] + as in + "ClientTransportPlugin trebuchet exec /usr/libexec/trebuchet --managed". + This example tells Tor to launch an external program to provide a + socks proxy for 'trebuchet' connections. The Tor client only + launches one instance of each external program with a given set of + options, even if the same executable and options are listed for + more than one method. + + In managed proxies, <methods> can be a comma-separated list of + pluggable transport method names, as in: + "ClientTransportPlugin pawn,bishop,rook exec /bin/ptproxy --managed". + + If instead of a transport method, the torrc lists "*" for a managed + proxy, Tor uses that proxy for all transport methods that the plugin + supports. So "ClientTransportPlugin * exec /usr/libexec/tor/foobar" + tells Tor that Tor should use the foobar plugin for every method that + the proxy supports. See the "Managed proxy interface" section below + for details on how Tor learns which methods a plugin supports. + + If two plugins support the same method, Tor should use whichever + one is listed first. + + The same program can implement a managed or an external proxy: it just + needs to take an argument saying which one to be. + +Server behavior + + Server proxies are configured similarly to client proxies. When + launching a proxy, the server must tell it what ORPort it has + configured, and what address (if any) it can listen on. The + server must tell the proxy which (if any) methods it should + provide if it can; the proxy needs to tell the server which + methods it is actually providing, and on what ports. + + When a client connects to the proxy, the proxy may need a way to + tell the server some identifier for the client address. It does + this in-band. + + As before, the server lists proxies in its torrc. These can be + external proxies that run on their own, or managed proxies that Tor + launches. + + An external server proxy is configured as + ServerTransportPlugin <method> proxy <address:port> <param=val> ... + as in + "ServerTransportPlugin trebuchet proxy 127.0.0.1:999 rocks=heavy". + The param=val pairs and the address are used to make the bridge + configuration information that we'll tell users. + + A managed proxy is configured as + ServerTransportPlugin <methods> exec </path/to/binary> [options] + or + ServerTransportPlugin * exec </path/to/binary> [options] + + When possible, Tor should launch only one binary of each binary/option + pair configured. So if the torrc contains + + ClientTransportPlugin foo exec /usr/bin/megaproxy --foo + ClientTransportPlugin bar exec /usr/bin/megaproxy --bar + ServerTransportPlugin * exec /usr/bin/megaproxy --foo + + then Tor will launch the megaproxy binary twice: once with the option + --foo and once with the option --bar. + +Managed proxy interface + + When the Tor client or relay launches a managed proxy, it communicates + via environment variables. At a minimum, it sets (in addition to the + normal environment variables inherited from Tor): + + {Client and server} + + "TOR_PT_STATE_LOCATION" -- A filesystem directory path where the + proxy should store state if it wants to. This directory is not + required to exist, but the proxy SHOULD be able to create it if + it doesn't. The proxy MUST NOT store state elsewhere. + Example: TOR_PT_STATE_LOCATION=/var/lib/tor/pt_state/ + + "TOR_PT_MANAGED_TRANSPORT_VER" -- To tell the proxy which + versions of this configuration protocol Tor supports. Future + versions will give a comma-separated list. Clients MUST accept + comma-separated lists containing any version that they + recognize, and MUST work correctly even if some of the versions + they don't recognize are non-numeric. Valid version characters + are non-space, non-comma printing ASCII characters. + Example: TOR_PT_MANAGED_TRANSPORT_VER=1,1a,2,4B + + {Client only} + + "TOR_PT_CLIENT_TRANSPORTS" -- A comma-separated list of which + methods this client should enable, or * if all methods should + be enabled. The proxy SHOULD ignore methods that it doesn't + recognize. + Example: TOR_PT_CLIENT_TRANSPORTS=trebuchet,battering_ram,ballista + + {Server only} + + "TOR_PT_EXTENDED_SERVER_PORT" -- An <address>:<port> where tor + should be listening for connections speaking the extended + ORPort protocol (See the "The extended ORPort protocol" section + below). If tor does not support the extended ORPort protocol, + it MUST use the empty string as the value of this environment + variable. + Example: TOR_PT_EXTENDED_SERVER_PORT=127.0.0.1:4200 + + "TOR_PT_ORPORT" -- Our regular ORPort in a form suitable + for local connections, i.e. connections from the proxy to + the ORPort. + Example: TOR_PT_ORPORT=127.0.0.1:9001 + + "TOR_PT_SERVER_BINDADDR" -- A comma seperated list of + <key>-<value> pairs, where <key> is a transport name and + <value> is the adress:port on which it should listen for client + proxy connections. + The keys holding transport names must appear on the same order + as they appear on TOR_PT_SERVER_TRANSPORTS. + This might be the advertised address, or might be a local + address that Tor will forward ports to. It MUST be an address + that will work with bind(). + Example: + TOR_PT_SERVER_BINDADDR=trebuchet-127.0.0.1:1984,ballista-127.0.0.1:4891 + + "TOR_PT_SERVER_TRANSPORTS" -- A comma-separated list of server + methods that the proxy should support, or * if all methods + should be enabled. The proxy SHOULD ignore methods that it + doesn't recognize. + Example: TOR_PT_SERVER_TRANSPORTS=trebuchet,ballista + + The transport proxy replies by writing NL-terminated lines to + stdout. The line metaformat is + + <Line> ::= <Keyword> <OptArgs> <NL> + <Keyword> ::= <KeywordChar> | <Keyword> <KeywordChar> + <KeyWordChar> ::= <any US-ASCII alphanumeric, dash, and underscore> + <OptArgs> ::= <Args>* + <Args> ::= <SP> <ArgChar> | <Args> <ArgChar> + <ArgChar> ::= <any US-ASCII character but NUL or NL> + <SP> ::= <US-ASCII whitespace symbol (32)> + <NL> ::= <US-ASCII newline (line feed) character (10)> + + Tor MUST ignore lines with keywords that it doesn't recognize. + + First, if there's an error parsing the environment variables, the + proxy should write: + ENV-ERROR <errormessage> + and exit. + + If the environment variables were correctly formatted, the proxy + should write: + VERSION <configuration protocol version> + to say that it supports this configuration protocol version (example + "VERSION 1"). It must either pick a version that Tor told it about + in TOR_PT_MANAGED_TRANSPORT_VER, or pick no version at all, say: + VERSION-ERROR no-version + and exit. + + The proxy should then open its ports. If running as a client + proxy, it should not use fixed ports; instead it should autoselect + ports to avoid conflicts. A client proxy should by default only + listen on localhost for connections. + + A server proxy SHOULD try to listen at a consistent port, though it + SHOULD pick a different one if the port it last used is now allocated. + + A client or server proxy then should tell which methods it has + made available and how. It does this by printing zero or more + CMETHOD and SMETHOD lines to its stdout. These lines look like: + + CMETHOD <methodname> socks4/socks5 <address:port> [ARGS=arglist] \ + [OPT-ARGS=arglist] + + as in + + CMETHOD trebuchet socks5 127.0.0.1:19999 ARGS=rocks,height \ + OPT-ARGS=tensile-strength + + The ARGS field lists mandatory parameters that must appear in + every bridge line for this method. The OPT-ARGS field lists + optional parameters. If no ARGS or OPT-ARGS field is provided, + Tor should not check the parameters in bridge lines for this + method. + + The proxy should print a single "CMETHODS DONE" line after it is + finished telling Tor about the client methods it provides. If it + tries to supply a client method but can't for some reason, it + should say: + CMETHOD-ERROR <methodname> <errormessage> + + A proxy should also tell Tor about the server methods it is providing + by printing zero or more SMETHOD lines. These lines look like: + + SMETHOD <methodname> <address:port> [options] + + If there's an error setting up a configured server method, the + proxy should say: + SMETHOD-ERROR <methodname> <errormessage> + as in + SMETHOD-ERROR trebuchet could not setup 'trebuchet' method + + The 'address:port' part of an SMETHOD line is the address to put + in the bridge line. The Options part is a list of space-separated + K:V flags that Tor should know about. Recognized options are: + + SMETHOD and CMETHOD lines may be interspersed, to allow the proxies to + report methods as they become available, even when some methods may + require probing your network, connecting to some kind of peers, etc + before they are set up. After the final SMETHOD line, the proxy says + "SMETHODS DONE". + + The proxy SHOULD NOT tell Tor about a server or client method + unless it is actually open and ready to use. + + Tor clients SHOULD NOT use any method from a client proxy or + advertise any method from a server proxy UNLESS it is listed as a + possible method for that proxy in torrc, and it is listed by the + proxy as a method it supports. + + Proxies should respond to a single INT signal by closing their + listener ports and not accepting any new connections, but keeping + all connections open, then terminating when connections are all + closed. Proxies should respond to a second INT signal by shutting + down cleanly. + + The managed proxy configuration protocol version defined in this + section is "1". + So, for example, if tor supports this configuration protocol it + should set the environment variable: + TOR_PT_MANAGED_TRANSPORT_VER=1
