From 2ec8ca5e6046b207eabe008101631b978758ac6d Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Tue, 12 Jan 2021 12:34:16 +0000 Subject: Remove SynapseRequest.get_user_agent (#9069) SynapseRequest is in danger of becoming a bit of a dumping-ground for "useful stuff relating to Requests", which isn't really its intention (its purpose is to override render, finished and connectionLost to set up the LoggingContext and write the right entries to the request log). Putting utility functions inside SynapseRequest means that lots of our code ends up requiring a SynapseRequest when there is nothing synapse-specific about the Request at all, and any old twisted.web.iweb.IRequest will do. This increases code coupling and makes testing more difficult. In short: move get_user_agent out to a utility function. --- synapse/handlers/auth.py | 6 +++--- synapse/handlers/sso.py | 5 +++-- 2 files changed, 6 insertions(+), 5 deletions(-) (limited to 'synapse/handlers') diff --git a/synapse/handlers/auth.py b/synapse/handlers/auth.py index f4434673dc..5b86ee85c7 100644 --- a/synapse/handlers/auth.py +++ b/synapse/handlers/auth.py @@ -49,8 +49,10 @@ from synapse.api.errors import ( UserDeactivatedError, ) from synapse.api.ratelimiting import Ratelimiter +from synapse.handlers._base import BaseHandler from synapse.handlers.ui_auth import INTERACTIVE_AUTH_CHECKERS from synapse.handlers.ui_auth.checkers import UserInteractiveAuthChecker +from synapse.http import get_request_user_agent from synapse.http.server import finish_request, respond_with_html from synapse.http.site import SynapseRequest from synapse.logging.context import defer_to_thread @@ -62,8 +64,6 @@ from synapse.util.async_helpers import maybe_awaitable from synapse.util.msisdn import phone_number_to_msisdn from synapse.util.threepids import canonicalise_email -from ._base import BaseHandler - if TYPE_CHECKING: from synapse.app.homeserver import HomeServer @@ -539,7 +539,7 @@ class AuthHandler(BaseHandler): # authentication flow. await self.store.set_ui_auth_clientdict(sid, clientdict) - user_agent = request.get_user_agent("") + user_agent = get_request_user_agent(request) await self.store.add_user_agent_ip_to_ui_auth_session( session.session_id, user_agent, clientip diff --git a/synapse/handlers/sso.py b/synapse/handlers/sso.py index 2da1ea2223..740df7e4a0 100644 --- a/synapse/handlers/sso.py +++ b/synapse/handlers/sso.py @@ -23,6 +23,7 @@ from typing_extensions import NoReturn, Protocol from twisted.web.http import Request from synapse.api.errors import Codes, RedirectException, SynapseError +from synapse.http import get_request_user_agent from synapse.http.server import respond_with_html from synapse.http.site import SynapseRequest from synapse.types import JsonDict, UserID, contains_invalid_mxid_characters @@ -362,7 +363,7 @@ class SsoHandler: attributes, auth_provider_id, remote_user_id, - request.get_user_agent(""), + get_request_user_agent(request), request.getClientIP(), ) @@ -628,7 +629,7 @@ class SsoHandler: attributes, session.auth_provider_id, session.remote_user_id, - request.get_user_agent(""), + get_request_user_agent(request), request.getClientIP(), ) -- cgit 1.5.1 From 0f8945e166b5f1965e69943e16c8220da74211bd Mon Sep 17 00:00:00 2001 From: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Date: Tue, 12 Jan 2021 12:48:12 +0000 Subject: Kill off `HomeServer.get_ip_from_request()` (#9080) Homeserver.get_ip_from_request() used to be a bit more complicated, but now it is totally redundant.

(#9081) If we have integrations with multiple identity providers, when the user does a UI Auth, we need to redirect them to the right one. There are a few steps to this. First of all we actually need to store the userid of the user we are trying to validate in the UIA session, since the /auth/sso/fallback/web request is unauthenticated. Then, once we get the /auth/sso/fallback/web request, we can fish the user id out of the session, and use it to look up the external id mappings, and hence pick an SSO provider for them. --- changelog.d/9081.feature | 1 + synapse/handlers/auth.py | 82 +++++++++++++++++++++++++------- synapse/handlers/sso.py | 31 ++++++++++++ synapse/handlers/ui_auth/__init__.py | 15 ++++++ synapse/rest/client/v2_alpha/account.py | 18 ++++--- synapse/rest/client/v2_alpha/auth.py | 33 +------------ synapse/rest/client/v2_alpha/register.py | 13 +++-- 7 files changed, 133 insertions(+), 60 deletions(-) create mode 100644 changelog.d/9081.feature (limited to 'synapse/handlers') diff --git a/changelog.d/9081.feature b/changelog.d/9081.feature new file mode 100644 index 0000000000..01a24dcf49 --- /dev/null +++ b/changelog.d/9081.feature @@ -0,0 +1 @@ +Add support for multiple SSO Identity Providers. diff --git a/synapse/handlers/auth.py b/synapse/handlers/auth.py index 2f5b2b61aa..4f881a439a 100644 --- a/synapse/handlers/auth.py +++ b/synapse/handlers/auth.py @@ -50,7 +50,10 @@ from synapse.api.errors import ( ) from synapse.api.ratelimiting import Ratelimiter from synapse.handlers._base import BaseHandler -from synapse.handlers.ui_auth import INTERACTIVE_AUTH_CHECKERS +from synapse.handlers.ui_auth import ( + INTERACTIVE_AUTH_CHECKERS, + UIAuthSessionDataConstants, +) from synapse.handlers.ui_auth.checkers import UserInteractiveAuthChecker from synapse.http import get_request_user_agent from synapse.http.server import finish_request, respond_with_html @@ -335,10 +338,10 @@ class AuthHandler(BaseHandler): request_body.pop("auth", None) return request_body, None -
