So this says to support password logins if:
- Password logins are enabled if one of:
- The local DB is enabled.
- A password provider supports password logins.
Is that correct?

yes, basically - which matches the code used to actually check the auth submission later.

Fix a minor bug where we would offer "m.login.password" login if a custom auth provider supported it, even if password login was disabled.
If local password auth is disabled, and no password providers provide it, we shouldn't offer it.

Looks like login_types really wants to be a set so we can just add things to it arbitrarily without having to check first.

yes, but see the comment just above.

Right, I suppose there's other ways to solve that, but no need to restructure the whole thing.

Synapse 1.24.0 (2020-12-09) =========================== 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](matrix-org/synapse#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. Internal Changes ---------------- - Add a maximum version for pysaml2 on Python 3.5. ([\#8898](matrix-org/synapse#8898)) 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](matrix-org/synapse#8878)) Internal Changes ---------------- - Add support for the `prometheus_client` newer than 0.9.0. Contributed by Jordan Bancino. ([\#8875](matrix-org/synapse#8875)) Synapse 1.24.0rc1 (2020-12-02) ============================== Features -------- - Add admin API for logging in as a user. ([\#8617](matrix-org/synapse#8617)) - Allow specification of the SAML IdP if the metadata returns multiple IdPs. ([\#8630](matrix-org/synapse#8630)) - Add support for re-trying generation of a localpart for OpenID Connect mapping providers. ([\#8801](matrix-org/synapse#8801), [\#8855](matrix-org/synapse#8855)) - Allow the `Date` header through CORS. Contributed by Nicolas Chamo. ([\#8804](matrix-org/synapse#8804)) - Add a config option, `push.group_by_unread_count`, which controls whether unread message counts in push notifications are defined as "the number of rooms with unread messages" or "total unread messages". ([\#8820](matrix-org/synapse#8820)) - Add `force_purge` option to delete-room admin api. ([\#8843](matrix-org/synapse#8843)) Bugfixes -------- - Fix a bug where appservices may be sent an excessive amount of read receipts and presence. Broke in v1.22.0. ([\#8744](matrix-org/synapse#8744)) - 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](matrix-org/synapse#8776)) - Fix a bug where synctl could spawn duplicate copies of a worker. Contributed by Waylon Cude. ([\#8798](matrix-org/synapse#8798)) - Allow per-room profiles to be used for the server notice user. ([\#8799](matrix-org/synapse#8799)) - Fix a bug where logging could break after a call to SIGHUP. ([\#8817](matrix-org/synapse#8817)) - Fix `register_new_matrix_user` failing with "Bad Request" when trailing slash is included in server URL. Contributed by @angdraug. ([\#8823](matrix-org/synapse#8823)) - Fix a minor long-standing bug in login, where we would offer the `password` login type if a custom auth provider supported it, even if password login was disabled. ([\#8835](matrix-org/synapse#8835)) - Fix a long-standing bug which caused Synapse to require unspecified parameters during user-interactive authentication. ([\#8848](matrix-org/synapse#8848)) - Fix a bug introduced in v1.20.0 where the user-agent and IP address reported during user registration for CAS, OpenID Connect, and SAML were of the wrong form.

Fix a minor bug where we would offer "m.login.password" login if a custom auth provider supported it, even if password login was disabled.
(It's worth noting that the subsequent attempt to log in would correctly fail - it was just the "available flows" that were wrong.)
Based on #8819.
