mod_rest: Do not allow replies to <iq type=result> from webhooks
Replying to a result stanza could cause loops, just as replying to an
error.
No stanza.name check here but it should be fine since no other kinds of
stanzas have type=result, and the boolean logic would most definitely be
wrong on the first attempt.

--- labels: - 'Stage-Beta' summary: 'TCP-over-XMPP :)' ... Introduction ============ It happens occasionally that I would like to use the XMPP server as a generic proxy for connecting to another service. It is especially awkward in some environments, and impossible in (for example) Javascript inside a web browser. Details ======= Using mod\_tcpproxy an XMPP client (including those using BOSH) can initiate a pipe to a given TCP/IP address and port. This implementation uses the [In-Band Bytestreams](http://xmpp.org/extensions/xep-0047.html) XEP, simply extended with 2 new attributes in a new namespace, host and port. An example Javascript client can be found in the web/ directory of mod\_tcpproxy in the repository. Configuration ============= Just add tcpproxy as a component, for example: `Component "tcp.example.com" "tcpproxy"` Protocol ======== A new stream is opened like this: ``` {.xml} <iq type="set" id="newconn1" to="tcp.example.com"> <open xmlns='http://jabber.org/protocol/ibb' sid='connection1' block-size='4096' stanza='message' xmlns:tcp='http://prosody.im/protocol/tcpproxy' tcp:host='example.com' tcp:port='80' /> </iq> ``` The stanza attribute (currently) MUST be 'message', and block-size is (currently) ignored. In response to this stanza you will receive a result upon connection success, or an error if the connection failed. You can then send to the connection by sending message stanzas as described in the IBB XEP. Incoming data will likewise be delivered as messages. Compatibility ============= ----- -------------- 0.7 Works 0.6 Doesn't work ----- -------------- Todo ==== - ACLs (restrict to certain JIDs, and/or certain target hosts/ports) - Honour block-size - Support iq stanzas for data transmission - Signal to start SSL/TLS on a connection
