From 96bad44f8783e6d54fd65e254072ca88031da241 Mon Sep 17 00:00:00 2001 From: Richard van der Hoff Date: Thu, 7 Jun 2018 18:14:08 +0100 Subject: [PATCH] Fix federation_client to send the right Host This appears to have stopped working since matrix.org moved to cloudflare. The Host header should match the name of the server, not whatever is in the SRV record. --- scripts-dev/federation_client.py | 65 +++++++++++++++++++++++++------- 1 file changed, 51 insertions(+), 14 deletions(-) diff --git a/scripts-dev/federation_client.py b/scripts-dev/federation_client.py index 3b28417376..d2acc7654d 100755 --- a/scripts-dev/federation_client.py +++ b/scripts-dev/federation_client.py @@ -18,14 +18,22 @@ from __future__ import print_function import argparse +from urlparse import urlparse, urlunparse + import nacl.signing import json import base64 import requests import sys + +from requests.adapters import HTTPAdapter import srvlookup import yaml +# uncomment the following to enable debug logging of http requests +#from httplib import HTTPConnection +#HTTPConnection.debuglevel = 1 + def encode_base64(input_bytes): """Encode bytes as a base64 string without any padding.""" @@ -113,17 +121,6 @@ def read_signing_keys(stream): return keys -def lookup(destination, path): - if ":" in destination: - return "https://%s%s" % (destination, path) - else: - try: - srv = srvlookup.lookup("matrix", "tcp", destination)[0] - return "https://%s:%d%s" % (srv.host, srv.port, path) - except: - return "https://%s:%d%s" % (destination, 8448, path) - - def request_json(method, origin_name, origin_key, destination, path, content): if method is None: if content is None: @@ -152,13 +149,19 @@ def request_json(method, origin_name, origin_key, destination, path, content): authorization_headers.append(bytes(header)) print ("Authorization: %s" % header, file=sys.stderr) - dest = lookup(destination, path) + dest = "matrix://%s%s" % (destination, path) print ("Requesting %s" % dest, file=sys.stderr) - result = requests.request( + s = requests.Session() + s.mount("matrix://", MatrixConnectionAdapter()) + + result = s.request( method=method, url=dest, - headers={"Authorization": authorization_headers[0]}, + headers={ + "Host": destination, + "Authorization": authorization_headers[0] + }, verify=False, data=content, ) @@ -242,5 +245,39 @@ def read_args_from_config(args): args.signing_key_path = config['signing_key_path'] +class MatrixConnectionAdapter(HTTPAdapter): + @staticmethod + def lookup(s): + if s[-1] == ']': + # ipv6 literal (with no port) + return s, 8448 + + if ":" in s: + out = s.rsplit(":",1) + try: + port = int(out[1]) + except ValueError: + raise ValueError("Invalid host:port '%s'" % s) + return out[0], port + + try: + srv = srvlookup.lookup("matrix", "tcp", s)[0] + return srv.host, srv.port + except: + return s, 8448 + + def get_connection(self, url, proxies=None): + parsed = urlparse(url) + + (host, port) = self.lookup(parsed.netloc) + netloc = "%s:%d" % (host, port) + print("Connecting to %s" % (netloc,), file=sys.stderr) + url = urlunparse(( + "https", netloc, parsed.path, parsed.params, parsed.query, + parsed.fragment, + )) + return super(MatrixConnectionAdapter, self).get_connection(url, proxies) + + if __name__ == "__main__": main()
