2019-01-07Improvements to signature verification (#9667)ThibG

2018-10-26Add locality check to ActivityPub::FetchRemoteAccountService (#9109)Eugen Rochko
* 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

2018-08-26Add CLI task for rotating keys (#8466)Eugen Rochko
* 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
2018-08-23Do not crash if remote custom emoji does not define updated date (fixes ↵ThibG

An explicit error allows user agents to know the error and Sidekiq to retry.
2018-05-14Fix account URI when updating ActivityPub account (#7488)Wiktor
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. [0]: https://github.com/tootsuite/mastodon/blob/03b69ebc450efc07246bd64204276941b7ede3fc/app/services/resolve_account_service.rb#L121
2018-05-12Fetch boosted statuses on behalf of a follower (fixes #7426) (#7459)ThibG
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.

2017-10-08Set snowflake IDs for backdated statuses (#5260)Eugen Rochko
- 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
2017-10-04Check Webfinger-returned author URI even when not redirected (#5213)ThibG
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.
2017-10-04Validate id of ActivityPub representations (#5114)Akihiko Odaki
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.

2017-09-12[WiP] Whenever a remote keypair changes, unfollow them and re-subscribe to ↵ThibG
… (#4907) * 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

2017-09-08Fetch statuses/following/followers numbers from ActivityPub collections (#4840)Eugen Rochko
2017-09-04Fix some ActivityPub JSON bugs (#4796)Eugen Rochko
- 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
2017-09-02Rename "locked" to "manuallyApprovesFollowers" in ActivityPub (#4779)Eugen Rochko
See: <https://www.w3.org/wiki/Activity_Streams_extensions#as:manuallyApprovesFollowers>
2017-09-02Define missing JSON-LD properties (#4767)Eugen Rochko
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.
