Nginx can be configured to bypass proxy cache when a special header
is in the request. If the response is cacheable, it will replace
the cache for that request. Proxy caching of media files is
desirable when using object storage as a way of minimizing bandwidth
costs, but has the drawback of leaving deleted media files for
a configured amount of cache time. A cache buster can make those
media files immediately unavailable. This especially makes sense
when suspending and unsuspending an account.
* feat: add possibility of adding WebAuthn security keys to use as 2FA
This adds a basic UI for enabling WebAuthn 2FA. We did a little refactor
to the Settings page for editing the 2FA methods – now it will list the
methods that are available to the user (TOTP and WebAuthn) and from
there they'll be able to add or remove any of them.
Also, it's worth mentioning that for enabling WebAuthn it's required to
have TOTP enabled, so the first time that you go to the 2FA Settings
page, you'll be asked to set it up.
This work was inspired by the one donde by Github in their platform, and
despite it could be approached in different ways, we decided to go with
this one given that we feel that this gives a great UX.

* feat: add request for WebAuthn as second factor at login if enabled
This commits adds the feature for using WebAuthn as a second factor for
login when enabled.
If users have WebAuthn enabled, now a page requesting for the use of a
WebAuthn credential for log in will appear, although a link redirecting
to the old page for logging in using a two-factor code will also be
present.

* feat: disable WebAuthn when an Admin disables 2FA for a user
Co-authored-by: Facundo Padula <facundo.padula@cedarcode.com>
* feat: remove ability to disable TOTP leaving only WebAuthn as 2FA
Following examples form other platforms like Github, we decided to make
Webauthn 2FA secondary to 2FA with TOTP, so that we removed the
possibility of removing TOTP authentication only, leaving users with
just WEbAuthn as 2FA. Instead, users will have to click on 'Disable 2FA'
in order to remove second factor auth.
The reason for WebAuthn being secondary to TOPT is that in that way,
users will still be able to log in using their code from their phone's
application if they don't have their security keys with them – or maybe
even lost them.
* We had to change a little the flow for setting up TOTP, given that now
it's possible to setting up again if you already had TOTP, in order to
let users modify their authenticator app – given that now it's not
possible for them to disable TOTP and set it up again with another
authenticator app.
So, basically, now instead of storing the new `otp_secret` in the
user, we store it in the session until the process of set up is
finished.
This was because, as it was before, when users clicked on 'Edit' in
the new two-factor methods lists page, but then went back without
finishing the flow, their `otp_secret` had been changed therefore
invalidating their previous authenticator app, making them unable to
log in again using TOTP.

* refactor: fix eslint errors
The PR build was failing given that linting returning some errors.
This commit attempts to fix them.
* refactor: normalize i18n translations
The build was failing given that i18n translations files were not
normalized.
This commits fixes that.
* refactor: avoid having the webauthn gem locked to a specific version
* refactor: use symbols for routes without '/'
* refactor: avoid sending webauthn disabled email when 2FA is disabled
When an admins disable 2FA for users, we were sending two mails
to them, one notifying that 2FA was disabled and the other to notify
that WebAuthn was disabled.
As the second one is redundant since the first email includes it, we can
remove it and send just one email to users.
* refactor: avoid creating new env variable for webauthn_origin config

Fixes#9776
The difficult part is autolinking, because Twitter-text's extractor does
some pretty ad-hoc stuff to find things that “look like” URLs, and XMPP
URIs do not really match the assumptions of that lib, so it doesn't sound
wise to try to shoehorn it into the existing regex.
This is why I used a specific regex (very close, although slightly more
permissive than the RFC), and a specific scan function (a simplified version
of the generalized one from Twitter).
* Remove leading “xmpp:” from auto-linked text
When authenticating via OAuth, the resource owner password grant
strategy is allowed by Mastodon, but (without this PR), it does not
attempt to authenticate against LDAP or PAM. As a result, LDAP or PAM
authenticated users cannot sign in to Mastodon with their
email/password credentials via OAuth (for instance, for native/mobile
app users).
This PR fleshes out the authentication strategy supplied to doorkeeper
in its initializer by looking up the user with LDAP and/or PAM when
devise is configured to use LDAP/PAM backends. It attempts to follow the
same logic as the Auth::SessionsController for handling email/password
credentials.
Note #1: Since this pull request affects an initializer, it's unclear
how to add test automation.
Note #2: The PAM authentication path has not been manually tested. It
was added for completeness sake, and it is hoped that it can be manually
tested before merging.

Change the behaviour of remotable concern. Previously, it would skip
downloading an attachment if the stored remote URL is identical to
the new one. Now it would not be skipped if the attachment is not
actually currently stored by Paperclip.
The default limit of 10 retries with exponential backoff meant
that if the S3 server was timing out, you would be stuck with it
for much, much longer than the 5 second read timeout we expect.
The uploading happens within a database transaction, which means
a failing S3 server could negatively affect database performance
It's possible that after commit callbacks were not firing when
exceptions occurred in the process. Also, the default Sidekiq
strategy does not push indexing jobs immediately, which is not
necessary and could be part of the issue too.

* Rate limit based on remote address IP, not on potential reverse proxy

* Rate-limit paging requests to one every 3 seconds
Deletions take a lot of resources to execute and cause a lot of
federation traffic, so it makes sense to decrease the number
someone can queue up through the API.
30 per 30 minutes
I also added "public" here, as I can't think of a good reason not to add it. Perhaps it has some marginal benefit in that ISPs (or other proxies) can cache it for all users. The assets are certainly publicly available and the same for all users.
* Add REST API for creating an account
The method is available to apps with a token obtained via the client
credentials grant. It creates a user and account records, as well as
an access token for the app that initiated the request. The user is
unconfirmed, and an e-mail is sent as usual.
The method returns the access token, which the app should save for
later. The REST API is not available to users with unconfirmed
accounts, so the app must be smart to wait for the user to click a
link in their e-mail inbox.
The method is rate-limited by IP to 5 requests per 30 minutes.
* Redirect users back to app from confirmation if they were created with an app
* Add tests
* Return 403 on the method if registrations are not open
* Require agreement param to be true in the API when creating an account
Right now, this includes three endpoints: host-meta, webfinger, and change-password.
host-meta and webfinger are publicly available and do not use any authentication. Nothing bad can be done by accessing them in a user's browser.
change-password being CORS-enabled will only reveal the URL it redirects to (which is /auth/edit) but not anything about the actual /auth/edit page, because it does not have CORS enabled.
The documentation for hosting an instance on a different domain should also be updated to point out that Access-Control-Allow-Origin: * should be set at a minimum for the /.well-known/host-meta redirect to allow browser-based non-proxied instance discovery.

A brief introduction to Same-Site cookies (and the difference between strict and
lax) can be found at
https://blog.mozilla.org/security/2018/04/24/same-site-cookies-in-firefox-60/
TLDR: We use lax since we want the cookies to be sent when the user navigates
safely from an external site.

If Mastodon accesses to the hidden service via transparent proxy, it's needed to avoid checking whether it's a private address, since `.onion` is resolved to a private address.
I was previously using the `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` to provide that function. However, I realized that using `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` is redundant, since this specification is always used with `ALLOW_ACCESS_TO_HIDDEN_SERVICE`. Therefore, I decided to integrate the setting of `HIDDEN_SERVICE_VIA_TRANSPARENT_PROXY` into` ALLOW_ACCESS_TO_HIDDEN_SERVICE`.
- POST /api/v1/push/subscription
- PUT /api/v1/push/subscription

- New OAuth scope: "push" (required for the above methods)
The previous rate limit allowed to post media so fast that it is possible
to fill up the disk space even before an administrator notices. The new
rate limit is configured so that it takes 24 hours to eat 10 gigabytes:
10 * 1024 / 8 / (24 * 60 / 30) = 27 (which rounded to 30)
The period is set long so that it does not prevent from attaching several
media to one post, which would happen in a short period. For example,
if the period is 5 minutes, the rate limit would be:
10 * 1024 / 8 / (24 * 60 / 5) = 4
This long period allows to lift the limit up.

CSRF token checking was enabled for API controllers in #6223,
producing "Can't verify CSRF token authenticity" log spam. This
disables logging of failed CSRF checks.
This also changes the protection strategy for
PushSubscriptionsController to use exceptions, making it consistent
with other controllers that use sessions.
Previously each protected path had a separate rate limit. Now they're all in the same bucket, so people are more likely to hit one with register->login. Increasing to 25 per 5 minutes should be fine.
* Add confirmation step for email changes
This adds a confirmation step for email changes of existing users.
Like the initial account confirmation, a confirmation link is sent
to the new address.
Additionally, a notification is sent to the existing address when
the change is initiated. This message includes instruction to reset
the password immediately or to contact the instance admin if the
change was not initiated by the account owner.
