| * | Handle the case of `get_missing_events` failingErik Johnston2019-04-101-9/+20
| | | | | | | | | | | | | | | | | | | | | Currently if a call to `/get_missing_events` fails we log an exception and stop processing the top level event we received over federation. Instead let's try and handle it sensibly given it is a somewhat expected failure mode.
* | | Add some logging to 3pid invite sig verification (#5015)David Baker2019-06-181-8/+38
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | I had to add quite a lot of logging to diagnose a problem with 3pid invites - we only logged the one failure which isn't all that informative. NB. I'm not convinced the logic of this loop is right: I think it should just accept a single valid signature from a trusted source rather than fail if *any* signature is invalid. Also it should probably not skip the rest of middle loop if a check fails? However, I'm deliberately not changing the logic here.

| * | Fix 3PID invite room state over federation.Erik Johnston2019-06-141-6/+0
| | | | | | | | | | | | | | | | | | | | | Fixes that when a user exchanges a 3PID invite for a proper invite over federation it does not include the `invite_room_state` key. This was due to synapse incorrectly sending out two invite requests.

| | | | | | | | | | | | | | | | | | | | When processing an incoming event over federation, we may try and resolve any unexpected differences in auth events. This is a non-essential process and so should not stop the processing of the event if it fails (e.g. due to the remote disappearing or not implementing the necessary endpoints). Fixes #3330

* Fixup calls to `comput_event_signature`Erik Johnston2019-01-291-1/+1
| | | | | | | | We currently pass FrozenEvent instead of `dict` to `compute_event_signature`, which works by accident due to `dict(event)` producing the correct result. This fixes PR #4493 commit 855a151

| * Split up event validation between event and builderErik Johnston2019-01-281-2/+5
| | | | | | | | | | | | | | | | | | The validator was being run on the EventBuilder objects, and so the validator only checked a subset of fields. With the upcoming EventBuilder refactor even fewer fields will be there to validate. To get around this we split the validation into those that can be run against an EventBuilder and those run against a fully fledged event.

| * | Store rejected remote invite events as outliersErik Johnston2019-01-231-32/+12
| |/ | | | | | | | | | | | | | | | | | | | | Currently they're stored as non-outliers even though the server isn't in the room, which can be problematic in places where the code assumes it has the state for all non outlier events. In particular, there is an edge case where persisting the leave event triggers a state resolution, which requires looking up the room version from state. Since the server doesn't have the state, this causes an exception to be thrown.

| | | | | | | | | | | | | | `on_new_notifications` and `on_new_receipts` in `HttpPusher` and `EmailPusher` now always return synchronously, so we can remove the `defer.gatherResults` on their results, and the `run_as_background_process` wrappers can be removed too because the PusherPool methods will now complete quickly enough.
* | Fix incorrect truncation in get_missing_eventsRichard van der Hoff2018-10-161-7/+5
|/ | | | | | | | | It's quite important that get_missing_events returns the *latest* events in the room; however we were pulling event ids out of the database until we got *at least* 10, and then taking the *earliest* of the results. We also shouldn't really be relying on depth, and should be checking the room_id.

* Include event when resolving state for missing prevsRichard van der Hoff2018-09-271-2/+16
| | | | | | | | | | | If we have a forward extremity for a room as `E`, and you receive `A`, `B`, s.t. `A -> B -> E`, and `B` also points to an unknown event `X`, then we need to do state res between `X` and `E`. When that happens, we need to make sure we include `X` in the state that goes into the state res alg. Fixes #3934.
* Include state from remote servers in pdu handlingRichard van der Hoff2018-09-271-4/+19
| | | | | | | | If we've fetched state events from remote servers in order to resolve the state for a new event, we need to actually pass those events into resolve_events_with_factory (so that it can do the state res) and then persist the ones we need - otherwise other bits of the codebase get confused about why we have state groups pointing to non-existent events.
* Fix "unhashable type: 'list'" exception in federation handlingRichard van der Hoff2018-09-271-7/+12
| | | | | | | | | | | | | get_state_groups returns a map from state_group_id to a list of FrozenEvents, so was very much the wrong thing to be putting as one of the entries in the list passed to resolve_events_with_factory (which expects maps from (event_type, state_key) to event id). We actually want get_state_groups_ids().values() rather than get_state_groups(). This fixes the main problem in #3923, but there are other problems with this bit of code which get discovered once you do so.

|/ | | | | | | | | | | transactions (#3959) when processing incoming transactions, it can be hard to see what's going on, because we process a bunch of stuff in parallel, and because we may end up recursively working our way through a chain of three or four events. This commit creates a way to use logcontexts to add the relevant event ids to the log lines.
* Comments and interface cleanup for on_receive_pduRichard van der Hoff2018-09-201-23/+46
| | | | | | | | Add some informative comments about what's going on here. Also, `sent_to_us_directly` and `get_missing` were doing the same thing (apart from in `_handle_queued_pdus`, which looks like a bug), so let's get rid of `get_missing` and use `sent_to_us_directly` consistently.
* Improve the logging when handling a federation transaction (#3904)Richard van der Hoff2018-09-191-55/+109
| | | | | | | | | | Let's try to rationalise the logging that happens when we are processing an incoming transaction, to make it easier to figure out what is going wrong when they take ages. In particular: - make everything start with a [room_id event_id] prefix - make sure we log a warning when catching exceptions rather than just turning them into other, more cryptic, exceptions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When synapse receives an event for a room its not in over federation, it double checks with the remote server to see if it is in fact in the room. This is done so that if the server has forgotten about the room (usually as a result of the database being dropped) it can recover from it. However, in the presence of state resets in large rooms, this can cause a lot of work for servers that have legitimately left. As a hacky solution that supports both cases we drop incoming events for rooms that we have explicitly left. This means that we no longer support the case of servers having forgotten that they've rejoined a room, but that is sufficiently rare that we're not going to support it for now.

| * When we do an invite rejection, save the signed leave event to the dbRichard van der Hoff2017-04-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | During a rejection of an invite received over federation, we ask a remote server to make us a `leave` event, then sign it, then send that with `send_leave`. We were saving the *unsigned* version of the event (which has a different event id to the signed version) to our db (and sending it to the clients), whereas other servers in the room will have seen the *signed* version. We're not aware of any actual problems that caused, except that it makes the database confusing to look at and generally leaves the room in a weird state.

* Queue up federation PDUs while a room join is in progressRichard van der Hoff2017-03-151-24/+44
| | | | | | | This just takes the existing `room_queues` logic and moves it out to `on_receive_pdu` instead of `_process_received_pdu`, which ensures that we don't start trying to fetch prev_events and whathaveyou until the join has completed.
* Move FederationServer._handle_new_pdu to FederationHandlerRichard van der Hoff2017-03-091-5/+197
| | | | | | | | | | | Unfortunately this significantly increases the size of the already-rather-big FederationHandler, but the code fits more naturally here, and it paves the way for the tighter integration that I need between handling incoming PDUs and doing the join dance. Other than renaming the existing `FederationHandler.on_receive_pdu` to `_process_received_pdu` to make way for it, this just consists of the move, and replacing `self.handler` with `self` and `self` with `self.replication_layer`.

| | | | | | | | | | | | | | When a server sends a third party invite another server may be the one that the inviting user registers with. In this case it is that remote server that will issue an actual invitation, and wants to do it "in the name of" the original invitee. However, the new proper invite will not be signed by the original server, and thus other servers would reject the invite if it was seen as coming from the original user. To fix this, a special case has been added to the auth rules whereby another server can send an invite "in the name of" another server's user, so long as that user had previously issued a third party invite that is now being accepted.
