* Fix webfinger redirect handling in ResolveAccountService
ResolveAccountService#process_webfinger! handled a one-step webfinger
redirection, but only accepting the result if it matched the exact URI passed
as input, defeating the point of a redirection check.
Instead, use the same logic as in `ActivityPub::FetchRemoteAccountService`,
updating the resulting `acct:` URI with the result of the first webfinger
query.
* Add tests
If someone tries logging in to an account and is prompted for a 2FA
code or sign-in token, even if the account's password or e-mail is
updated in the meantime, the session will show the prompt and allow
the login process to complete with a valid 2FA code or sign-in token
* Add support for followers synchronization on the receiving end
Check the `collectionSynchronization` attribute on `Create` and `Announce`
activities and synchronize followers from provided collection if possible.
* Add tests for followers synchronization on the receiving end
* Add support for follower synchronization on the sender's end
* Add tests for the sending end
* Switch from AS attributes to HTTP header
Replace the custom `collectionSynchronization` ActivityStreams attribute by
an HTTP header (`X-AS-Collection-Synchronization`) with the same syntax as
the `Signature` header and the following fields:
- `collectionId` to specify which collection to synchronize
- `digest` for the SHA256 hex-digest of the list of followers known on the
receiving instance (where “receiving instance” is determined by accounts
sharing the same host name for their ActivityPub actor `id`)
- `url` of a collection that should be fetched by the instance actor
Internally, move away from the webfinger-based `domain` attribute and use
account `uri` prefix to group accounts.
* Add environment variable to disable followers synchronization
Since the whole mechanism relies on some new preconditions that, in some
extremely rare cases, might not be met, add an environment variable
(DISABLE_FOLLOWERS_SYNCHRONIZATION) to disable the mechanism altogether and
avoid followers being incorrectly removed.
The current conditions are:
1. all managed accounts' actor `id` and inbox URL have the same URI scheme and
netloc.
2. all accounts whose actor `id` or inbox URL share the same URI scheme and
netloc as a managed account must be managed by the same Mastodon instance
as well.
As far as Mastodon is concerned, breaking those preconditions require extensive
configuration changes in the reverse proxy and might also cause other issues.
Therefore, this environment variable provides a way out for people with highly
unusual configurations, and can be safely ignored for the overwhelming majority
of Mastodon administrators.
* Only set follower synchronization header on non-public statuses
This is to avoid unnecessary computations and allow Follow-related
activities to be handled by the usual codepath instead of going through
the synchronization mechanism (otherwise, any Follow/Undo/Accept activity
would trigger the synchronization mechanism even if processing the activity
itself would be enough to re-introduce synchronization)
* Change how ActivityPub::SynchronizeFollowersService handles follow requests
If the remote lists a local follower which we only know has sent a follow
request, consider the follow request as accepted instead of sending an Undo.
* Integrate review feeback
- rename X-AS-Collection-Synchronization to Collection-Synchronization
- various minor refactoring and code style changes
* Only select required fields when computing followers_hash
* Use actor URI rather than webfinger domain in synchronization endpoint
* Change hash computation to be a XOR of individual hashes
Makes it much easier to be memory-efficient, and avoid sorting discrepancy issues.
* Marginally improve followers_hash computation speed
* Further improve hash computation performances by using pluck_each
There are edge cases where requests to certain hosts timeout when
using the vanilla HTTP.rb gem, which the goldfinger gem uses. Now
that we no longer need to support OStatus servers, webfinger logic
is so simple that there is no point encapsulating it in a gem, so
we can just use our own Request class. With that, we benefit from
more robust timeout code and IPv4/IPv6 resolution.
Fix#14091
* Add bell button
Fix#4890
* Remove duplicate type from post-deployment migration
* Fix legacy class type mappings
* Improve query performance with better index
* Fix validation
* Remove redundant index from notifications
* Do not serve account actors at all in limited federation mode
When an account is fetched without a signature from an allowed instance,
return an error.
This isn't really an improvement in security, as the only information that was
previously returned was required protocol-level info, and the only personal bit
was the existence of the account. The existence of the account can still be
checked by issuing a webfinger query, as those are accepted without signatures.
However, this change makes it so that unallowed instances won't create account
records on their end when they find a reference to an unknown account.
The previous behavior of rendering a limited list of fields, instead of not
rendering the actor at all, was in order to prevent situations in which two
instances in Authorized Fetch mode or Limited Federation mode would fail to
reach each other because resolving an account would require a signed query…
from an account which can only be fetched with a signed query itself. However,
this should now be fine as fetching accounts is done by signing on behalf of
the special instance actor, which does not require any kind of valid signature
to be fetched.
* Fix tests
* Check for and record reblog info atomically
Instead of using ZREVRANK to determine whether a reblog is a new reblog or not,
use ZADD's NX option to perform the check/addition option atomically.
* Replace ZREVRANK call with ZSCORE key which is more efficient
* Make tests a bit stricter
* Fix off-by-one
* Add database support for list show-reply preferences
* Add backend support to read and update list-specific show_replies settings

* Capitalize replies_policy strings
* Change radio button design to be consistent with that of the directory explorer
* 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.

* Increase DNS timeout from 1 second to 5 seconds for MX check
1 seconds is rather short when using a recursive DNS resolver which
hasn't got a cached result already available. Use 5 seconds instead,
which is the timeout value we use for outgoing HTTP queries.
* Add more precise error messages for invalid e-mail addresses
* Change content-type to be always computed from file data
Restore previous behavior, detecting the content-type isn't very
expensive, and some instances may serve files as application/octet-stream
regardless of their true type, making fetching media from them fail, while
it used to work pre-3.2.0.
* Add test
* Fix not handling Undo on some activity types when they aren't inlined
When receiving an Undo for a non-inlined activity, try looking it up in
database using the URI. The queries are ad-hoc because we don't have a global
index of object URIs, and not all activity types are stored in database with
an index on their URI.
Announces are just statuses, and have an index on URIs, so this check can
be done efficiently.
Accepts cannot be handled at all because we don't record their URI at any
point.
Follows don't have an index on URI, but they have an index on the issuing
account, which should make such queries largely manageable.
Likes don't have an index on URI, they have an index on the issuing account,
but the number of favs per account may be very high, so I decided not to
handle that.
Blocks don't have an index on URI, but they have an index on the issuing
account, which should make such queries largely manageable.
In all cases, if an Undo could not be handled properly, we call `delete_later!`
because that does not require us to know more than the URI of the undone
property.
* Add tests
* Make newer blocks overwrite older ones
Allows re-synchronizing block info by re-blocking and un-blocking again
when the original Undo Block has been lost.
* Add tests for some cachable responses
This only covers responses that we should have managed to make cachable
so far. It's not the case of all responses that should be cachable in
the end.
* Fix RSS feeds not being cachable
* Change move handler to carry blocks and mutes over
When user A blocks user B and B moves to a new account C, make A block C
accordingly.
Note that it only works if A's instance is aware of the Move, that is,
if B is on A's instance or has followers there.
* Also notify instances with known people blocking you when moving
* Add automatic account notes when blocking/muting an account that had no note
* Add UserNote model
* Add UI for user notes
* Put comment in relationships entity
* Add API to create user notes
* Copy user notes to new account when receiving a Move activity
* Address some of the review remarks
* Replace modal by inline edition
* Please CodeClimate
* Button design changes
* Change design again
* Cancel note edition when pressing Escape
* Fixes
* Tweak design again
* Move “Add note” item, and allow users to add notes to themselves
* Rename UserNote into AccountNote, rename “comment” Relationship attribute to “note”
- Change audio files to not be stripped of metadata
- Automatically extract cover art from audio if it exists
- Add `thumbnail` parameter to `POST /api/v1/media`, `POST /api/v2/media` and `PUT /api/v1/media/:id`
- Add `icon` to represent it in attachments in ActivityPub
- Fix `preview_url` containing URL of missing missing image when there is no thumbnail instead of null

* Split media cleanup from reject-media domain blocks to its own service
* Slightly improve ClearDomainMediaService error handling
* Lower DomainClearMediaWorker to lowest-priority queue
* Do not catch ActiveRecord::RecordNotFound in domain block workers
* Fix DomainBlockWorker spec labels
* Add some specs
* Change domain blocks to immediately mark accounts as suspended
Rather than doing so sequentially, account after account, while cleaning
their data. This doesn't change much about the time the block takes to
complete, but it immediately prevents interaction with the blocked domain,
while up to now, it would only be guaranteed when the process ends.
