* move simple_async_mock to test_utils
... so that it can be re-used
* Remove references to `SamlHandler._map_saml_response_to_user` from tests
This method is going away, so we can no longer use it as a test point. Instead,
factor out a higher-level method which takes a SAML object, and verify correct
behaviour by mocking out `AuthHandler.complete_sso_login`.
* changelog
* Remove references to handler._auth_handler
(and replace them with hs.get_auth_handler)
* Factor out a utility function for building Requests
* Remove mocks of `OidcHandler._map_userinfo_to_user`
This method is going away, so mocking it out is no longer a valid approach.
Instead, we mock out lower-level methods (eg _remote_id_from_userinfo), or
simply allow the regular implementation to proceed and update the expectations
accordingly.
* Remove references to `OidcHandler._map_userinfo_to_user` from tests
This method is going away, so we can no longer use it as a test point. Instead
we build mock "callback" requests which we pass into `handle_oidc_callback`,
and verify correct behaviour by mocking out `AuthHandler.complete_sso_login`.
* Factor out _call_attribute_mapper and _register_mapped_user
This is mostly an attempt to simplify `get_mxid_from_sso`.
* Move mapping_lock down into SsoHandler.
It seems that letting CircleCI use its default docker version (17.09.0-ce,
apparently) did not interact well with multiarch builds: in particular, we saw
weird effects where running an amd64 build at the same time as an arm64 build
caused the arm64 builds to fail with:
Error while loading /usr/sbin/dpkg-deb: No such file or directory
===========================
Due to the two security issues highlighted below, server administrators are
encouraged to update Synapse. We are not aware of these vulnerabilities being
exploited in the wild.
Security advisory
-----------------
The following issues are fixed in v1.23.1 and v1.24.0.
- There is a denial of service attack
([CVE-2020-26257](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26257))
against the federation APIs in which future events will not be correctly sent
to other servers over federation. This affects all servers that participate in
open federation. (Fixed in [#8776](https://github.com/matrix-org/synapse/pull/8776)).
- Synapse may be affected by OpenSSL
[CVE-2020-1971](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-1971).
Synapse administrators should ensure that they have the latest versions of
the cryptography Python package installed.
To upgrade Synapse along with the cryptography package:
* Administrators using the [`matrix.org` Docker
image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu
packages from
`matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages)
should ensure that they have version 1.24.0 or 1.23.1 installed: these images include
the updated packages.
* Administrators who have [installed Synapse from
source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
should upgrade the cryptography package within their virtualenv by running:
```sh
<path_to_virtualenv>/bin/pip install 'cryptography>=3.3'
```
* Administrators who have installed Synapse from distribution packages should
consult the information from their distributions.
Bugfixes
--------
- Fix a bug in some federation APIs which could lead to unexpected behaviour if different parameters were set in the URI and the request body. ([\#8776](https://github.com/matrix-org/synapse/issues/8776))
Internal Changes
----------------
- Add a maximum version for pysaml2 on Python 3.5. ([\#8898](https://github.com/matrix-org/synapse/issues/8898))

Internal Changes
----------------
- Add a maximum version for pysaml2 on Python 3.5. ([\#8898](https://github.com/matrix-org/synapse/issues/8898))
* Consistently use room_id from federation request body
Some federation APIs have a redundant `room_id` path param (see
https://github.com/matrix-org/matrix-doc/issues/2330). We should make sure we
consistently use either the path param or the body param, and the body param is
easier.
* Kill off some references to "context"
Once upon a time, "rooms" were known as "contexts". I think this kills of the
last references to "contexts".
The idea is that the parse_config method of extension modules can raise either a ConfigError or a JsonValidationError,
and it will be magically turned into a legible error message. There's a few components to it:
* Separating the "path" and the "message" parts of a ConfigError, so that we can fiddle with the path bit to turn it
into an absolute path.
* Generally improving the way ConfigErrors get printed.
* Passing in the config path to load_module so that it can wrap any exceptions that get caught appropriately.
* SsoHandler: remove inheritance from BaseHandler
* Simplify the flow for SSO UIA
We don't need to do all the magic for mapping users when we are doing UIA, so
let's factor that out.
* Call set_avatar_url with target_user, not user_id
Fixes https://github.com/matrix-org/synapse/issues/8871

Merge tag 'v1.24.0rc2' into develop
Synapse 1.24.0rc2 (2020-12-04)
==============================
Bugfixes
--------
- Fix a regression in v1.24.0rc1 which failed to allow SAML mapping providers which were unable to redirect users to an additional page. ([\#8878](https://github.com/matrix-org/synapse/issues/8878))
Internal Changes
----------------
- Add support for the `prometheus_client` newer than 0.9.0. Contributed by Jordan Bancino. ([\#8875](https://github.com/matrix-org/synapse/issues/8875))
This removes the version pin of the `prometheus_client` dependency, in direct response to #8831. If merged, this will close#8831
As far as I can tell, no other changes are needed, but as I'm no synapse expert, I'm relying heavily on CI and maintainer reviews for this. My very primitive test of synapse with prometheus_client v0.9.0 on my home server didn't bring up any issues, so we'll see what happens.
