* Enforce validity period on server_keys for fed requests. (#5321)Richard van der Hoff2019-06-032-3/+5
| | | | | | | | When handling incoming federation requests, make sure that we have an up-to-date copy of the signing key. We do not yet enforce the validity period for event signatures.

* Fix error handling for rooms whose versions are unknown. (#5219)Richard van der Hoff2019-05-211-1/+13
| | | | | | | If we remove support for a particular room version, we should behave more gracefully. This should make client requests fail with a 400 rather than a 500, and will ignore individiual PDUs in a federation transaction, rather than the whole transaction.

* add options to require an access_token to GET /profile and /publicRooms on ↵Matthew Hodgson2019-05-081-0/+10
| | | | | | | | | | | | | | | | | CS API (#5083) This commit adds two config options: * `restrict_public_rooms_to_local_users` Requires auth to fetch the public rooms directory through the CS API and disables fetching it through the federation API. * `require_auth_for_profile_requests` When set to `true`, requires that requests to `/profile` over the CS API are authenticated, and only returns the user's profile if the requester shares a room with the profile's owner, as per MSC1301. MSC1301 also specifies a behaviour for federation (only returning the profile if the server asking for it shares a room with the profile's owner), but that's currently really non-trivial to do in a not too expensive way. Next step is writing down a MSC that allows a HS to specify which user sent the profile query. In this implementation, Synapse won't send a profile query over federation if it doesn't believe it already shares a room with the profile's owner, though. Groups have been intentionally omitted from this commit.

* Use event streams to calculate presenceErik Johnston2019-03-272-3/+89
| | | | | | | | | | | | | | | | | Primarily this fixes a bug in the handling of remote users joining a room where the server sent out the presence for all local users in the room to all servers in the room. We also change to using the state delta stream, rather than the distributor, as it will make it easier to split processing out of the master process (as well as being more flexible). Finally, when sending presence states to newly joined servers we filter out old presence states to reduce the number sent. Initially we filter out states that are offline and have a last active more than a week ago, though this can be changed down the line. Fixes #3962

* Remove trailing slashes from outbound federation requests and retry on 400 ↵Andrew Morgan2019-03-211-7/+14
|\ | | | | | | | | (#4840) As per #3622, we remove trailing slashes from outbound federation requests. However, to ensure that we remain backwards compatible with previous versions of Synapse, if we receive a HTTP 400 with `M_UNRECOGNIZED`, then we are likely talking to an older version of Synapse in which case we retry with a trailing slash appended to the request path.

The OpenID userinfo endpoint is called by integration managers to verify user actions using the client API OpenID access token. Without this verification, the integration manager cannot know that the access token is valid. The OpenID userinfo endpoint will be loaded in the case that either "federation" or "openid" resource is defined. The new "openid" resource is defaulted to active in default configuration.

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.

Blocking localhost, on the other hand, means that you get a surprise when trying to connect a test server on localhost to an existing server (with a 'normal' server_name).

| * | Refactor code for turning HttpResponseException into SynapseErrorRichard van der Hoff2018-08-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This commit replaces SynapseError.from_http_response_exception with HttpResponseException.to_synapse_error. The new method actually returns a ProxiedRequestError, which allows us to pass through additional metadata from the API call.
| * | Be more careful which errors we send back over the C-S APIRichard van der Hoff2018-08-011-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We really shouldn't be sending all CodeMessageExceptions back over the C-S API; it will include things like 401s which we shouldn't proxy. That means that we need to explicitly turn a few HttpResponseExceptions into SynapseErrors in the federation layer. The effect of the latter is that the matrix errcode will get passed through correctly to calling clients, which might help with some of the random M_UNKNOWN errors when trying to join rooms.

| | | | | | | | | | | | | | | | This fixes #3518, and ensures that we get useful logs and metrics for lots of things that happen in the background. (There are certainly more things that happen in the background; these are just the common ones I've found running a single-process synapse locally).
* | Resource tracking for background processesRichard van der Hoff2018-07-181-5/+7
|/ | | | | | | | | | | | | | | | This introduces a mechanism for tracking resource usage by background processes, along with an example of how it will be used. This will help address #3518, but more importantly will give us better insights into things which are happening but not being shown up by the request metrics. We *could* do this with Measure blocks, but: - I think having them pulled out as a completely separate metric class will make it easier to distinguish top-level processes from those which are nested. - I want to be able to report on in-flight background processes, and I don't think we want to do this for *all* Measure blocks.

|/ | | | | | | | | | | | | | | | | | There were a bunch of places where we fire off a process to happen in the background, but don't have any exception handling on it - instead relying on the unhandled error being logged when the relevent deferred gets garbage-collected. This is unsatisfactory for a number of reasons: - logging on garbage collection is best-effort and may happen some time after the error, if at all - it can be hard to figure out where the error actually happened. - it is logged as a scary CRITICAL error which (a) I always forget to grep for and (b) it's not really CRITICAL if a background process we don't care about fails. So this is an attempt to add exception handling to everything we fire off into the background.

This will be largely non-functional, but does include the following functional changes: * federation_server.on_context_state_request: drops use of _server_linearizer which looked redundant and could cause incorrect cache misses by yielding between the get and the set. * RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks * the wrap function includes some logging. I'm hoping this won't be too noisy on production.

It turns out that sortedcontainers.SortedDict is not an exact match for blist.sorteddict; in particular, `popitem()` removes things from the opposite end of the dict. This is trivial to fix, but I want to add some unit tests, and potentially some more thought about it, before we do so.
