* Refactor signature verification a bit
* Rescue signature verification if recorded public key is invalid
Fixes#8822
* Always re-fetch AP signing key when HTTP Signature verification fails
But when the account is not marked as stale, avoid fetching collections and
media, and avoid webfinger round-trip.
* Apply stoplight to key/account update as well as initial key retrieval
* Do not LDS-sign Follow, Accept, Reject, Undo, Block
* Do not use LDS for Create activities of private toots
* Minor cleanup
* Ignore unsigned activities instead of misattributing them
* Use status.distributable? instead of querying visibility directly
* Add locality check to ActivityPub::FetchRemoteAccountService
Fix#8643
Because there are a few places where it is called, it is difficult
to confirm if they all previously checked it for locality. It's better
to make sure within the service.
* Remove faux-remote duplicates of local accounts
* Verify link ownership with rel="me"
* Add explanation about verification to UI
* Perform link verifications
* Add click-to-copy widget for verification HTML
* Redesign edit profile page
* Redesign forms
* Improve responsive design of settings pages
* Restore landing page sign-up form
* Fix typo
* Support <link> tags, add spec
* Fix links not being verified on first discovery and passive updates
* If an Update is signed with known key, skip re-following procedure
Because it means the remote actor did *not* lose their database
* Add CLI method for rotating keys
bin/tootctl accounts rotate [USERNAME]
Generates a new RSA key per account and sends out an Update activity
signed with the old key.
* Key rotation: Space out Update fan-outs every 5 minutes per 1000 accounts
* Skip suspended accounts in key rotation
Updates account `uri` field on each call to `update_account` instead of
only once during `create_account` to mirror the same behavior in OStatus
`ResolveAccountService` class [0].
ActivityPub accounts are identified using `@username` and `@domain` pair
instead of URI since #6842.
This fixes#7479: a bug when the account identified by `@username` and
`@domain` changes its URI.

When an ActivityPub Announce is processed and the boosted toot is not known,
fetch it on behalf of one of the booster's followers. This is to allow
fetching self-boosts of previously-unknown private toots.
If fetching on behalf of a user fails, try fetching it anonymously: the
selected follower of a boosting user may be banned by the boosted toot's
author.
* Add equals_or_includes_any? helper in JsonLdHelper
* Support arrays in JSON-LD type fields for actors/tags/objects.
* Spec for resolving accounts with extension types
* Style tweaks for codeclimate
* Add bio fields
- Fix#3211
- Fix#232
- Fix#121
* Display bio fields in web UI
* Fix output of links and missing fields
* Federate bio fields over ActivityPub as PropertyValue
* Improve how the fields are stored, add to Edit profile form
* Add rel=me to links in fields
Fix#121
* Fix actors accepting invalid URI schemes or different host between URI and URL
* Fix statuses accepting invalid URI scheme or different host to actor
* Adjust tests to new requirements
* Improve readability of mismatching_origin?/invalid_origin? methods
* Add semi-support for Video/Image objects in ActivityPub
Video and Image objects will create corresponding status records
with manually crafted text contents (title + URL)
* Extract html-url-finding logic into JsonLdHelper
* Fallback to id when url missing, extract supported object types
* Serialize moved accounts into REST and ActivityPub APIs
* Parse federated moved accounts from ActivityPub
* Add note about moved accounts to public profiles
* Add moved account message to web UI
* Fix code style issues
- Rename Mastodon::TimestampIds into Mastodon::Snowflake for clarity
- Skip for statuses coming from inbox, aka delivered in real-time
- Skip for statuses that claim to be from the future
The whole point of verified_webfinger? is to check the WebFinger-discoverable
URI maps back to the known author URI. This was not actually verified if the
first Webfinger request was not a redirection.
Additionally, ActivityPub::FetchRemoteStatusService no longer parses
activities.
OStatus::Activity::Creation no longer delegates to ActivityPub because
the provided ActivityPub representations are not signed while OStatus
representations are.
* Whenever a remote keypair changes, unfollow them and re-subscribe to them
In Mastodon (it could be different for other OStatus or AP-enabled software),
a keypair change is indicative of whole user (or instance) data loss. In this
situation, the “new” user might be different, and almost certainly has an empty
followers list. In this case, Mastodon instances will disagree on follower
lists, leading to unreliable delivery and “shadow followers”, that is users
believed by a remote instance to be followers, without the affected user
knowing.
Drawbacks of this change are:
1. If an user legitimately changes public key for some reason without losing
data (not possible in Mastodon at the moment), they will have their remote
followers unsubscribed/re-subscribed needlessly.
2. Depending of the number of remote followers, this may generate quite some
traffic.
3. If the user change is an attempt at usurpation, the remote followers will
unknowingly follow the usurper. Note that this is *not* a change of
behavior, Mastodon already behaves like that, although delivery might be
unreliable, and the usurper would not have known the former user's
followers.
* Rename ResubscribeWorker to RefollowWorker
* Process followers in batches
- Fix assumption that `url` is always a string. Handle it if it's an
array of strings, array of objects, object, or string, both for
accounts and for objects
- `sharedInbox` is actually supposed to be under `endpoints`, handle
both cases and adjust the serializer
Using _: property names is discouraged, as in the future,
canonicalization may throw an error when encountering that instead
of discarding it silently like it does now.
We are defining some ActivityStreams properties which we expect
to land in ActivityStreams eventually, to ensure that future versions
of Mastodon will remain compatible with this even once that happens.
Those would be `locked`, `sensitive` and `Hashtag`
We are defining a custom context inline for some properties which we
do not expect to land in any other context. `atomUri`, `inReplyToAtomUri`
and `conversation` are part of the custom defined OStatus context.
* Add handling of Linked Data Signatures in payloads
* Add a way to sign JSON, fix canonicalization of signature options
* Fix signatureValue encoding, send out signed JSON when distributing
* Add missing security context
