We incorrectly used `room_id` as to bound the result set, even though we
order by `joined_members, room_id`, leading to incorrect results after
pagination.
Copy push rules during a room upgrade from the old room to the new room, instead of deleting them from the old room.
For instance, we've defined upgrading of a room multiple times to be possible, and push rules won't be transferred on the second upgrade if they're deleted during the first.
Also fix some missing yields that probably broke things quite a bit.
While this is not documented in the spec (but should be), Riot (and other clients) revoke 3PID invites by sending a m.room.third_party_invite event with an empty ({}) content to the room's state.
When the invited 3PID gets associated with a MXID, the identity server (which doesn't know about revocations) sends down to the MXID's homeserver all of the undelivered invites it has for this 3PID. The homeserver then tries to talk to the inviting homeserver in order to exchange these invite for m.room.member events.
When one of the invite is revoked, the inviting homeserver responds with a 500 error because it tries to extract a 'display_name' property from the content, which is empty. This might cause the invited server to consider that the server is down and not try to exchange other, valid invites (or at least delay it).
This fix handles the case of revoked invites by avoiding trying to fetch a 'display_name' from the original invite's content, and letting the m.room.member event fail the auth rules (because, since the original invite's content is empty, it doesn't have public keys), which results in sending a 403 with the correct error message to the invited server.
We have set the max retry interval to a value larger than a postgres or
sqlite int can hold, which caused exceptions when updating the
destinations table.
To fix postgres we need to change the column to a bigint, and for sqlite
we lower the max interval to 2**62 (which is still incredibly long).
Joining against `events` and ordering by `stream_ordering` is
inefficient as it forced scanning the entirety of the redactions table.
This isn't the case if we use `redactions.received_ts` column as we can
then use an index.
Currently we don't set `have_censored` column if we don't have the
target event of a redaction, which means we repeatedly attempt to censor
the same non-existant event.
When we persist non-redacted events we unset the `have_censored` column
for any redactions that target said event.
Doing a password reset via SMS has never worked, and in any case is a silly
idea because msisdn recycling is a thing.

Pull the checkers out to their own classes, rather than having them lost in a
massive 1000-line class which does everything.
This is also preparation for some more intelligent advertising of flows, as per #6100
We don't actually care about what happens in `get_user_by_req` and
having it as a separate span means that the entity tag isn't added to
the servlet spans, making it harder to search.
because, frankly, it looked like it was written by an axe-murderer.
This should be a non-functional change, except that where `m.login.dummy` was
previously advertised *before* `m.login.terms`, it will now be advertised
afterwards. AFAICT that should have no effect, and will be more consistent with
the flows that involve passing a 3pid.
Second part of solving #6076Fixes#6076
We return a submit_url parameter on calls to POST */msisdn/requestToken so that clients know where to submit token information to.
Uses a SimpleHttpClient instance equipped with the federation_ip_range_blacklist list for requests to identity servers provided by user input. Does not use a blacklist when contacting identity servers specified by account_threepid_delegates. The homeserver trusts the latter and we don't want to prevent homeserver admins from specifying delegates that are on internal IP addresses.
Fixes#5935
As MSC2263 states, m.require_identity_server must be set to false when it does not require an identity server to be provided by the client for the purposes of email registration or password reset.
Adds an m.require_identity_server flag to /versionss unstable_flags section. This will advertise that Synapse no longer needs id_server as a parameter.
This is a) simpler than querying user_ips directly and b) means we can
purge older entries from user_ips without losing the required info.
The storage functions now no longer return the access_token, since it
was unused.
Implements MSC2290. This PR adds two new endpoints, /unstable/account/3pid/add and /unstable/account/3pid/bind. Depending on the progress of that MSC the unstable prefix may go away.
This PR also removes the blacklist on some 3PID tests which occurs in #6042, as the corresponding Sytest PR changes them to use the new endpoints.
Finally, it also modifies the account deactivation code such that it doesn't just try to deactivate 3PIDs that were bound to the user's account, but any 3PIDs that were bound through the homeserver on that user's account.
Fixes#6066
This register endpoint should be disabled if registration is disabled, otherwise we're giving anyone the ability to check if a username exists on a server when we don't need to be.
Error code is 403 (Forbidden) as that's the same returned by /register when registration is disabled.
In ancient times Synapse would only send emails when it was notifying a user about a message they received...
Now it can do all sorts of neat things!
Change the logging so it's not just about notifications.
Remove trailing slash ability from the password reset submit_token endpoint. Since we provide the link in an email, and have never sent it with a trailing slash, there's no point for us to accept them on the endpoint.
The validation links sent via email had their query parameters inserted without any URL-encoding. Surprisingly this didn't seem to cause any issues, but if a user were to put a `/` in their client_secret it could lead to problems.
Fixes a bug where the default attribute maps were prioritised over
user-specified ones, resulting in incorrect mappings.
The problem is that if you call SPConfig.load() multiple times, it adds new
attribute mappers to a list. So by calling it with the default config first,
and then the user-specified config, we would always get the default mappers
before the user-specified mappers.
To solve this, let's merge the config dicts first, and then pass them to
SPConfig.
This is a partial revert of #5893. The problem is that if we drop these tables
in the same release as removing the code that writes to them, it prevents users
users from being able to roll back to a previous release.
So let's leave the tables in place for now, and remember to drop them in a
subsequent release.
(Note that these tables haven't been *read* for *years*, so any missing rows
resulting from a temporary upgrade to vNext won't cause a problem.)
Removes the POST method from `/password_reset/<medium>/submit_token/` as it's only used by phone number verification which Synapse does not support yet.
3PID invites require making a request to an identity server to check that the invited 3PID has an Matrix ID linked, and if so, what it is.
These requests are being made on behalf of a user. The user will supply an identity server and an access token for that identity server. The homeserver will then forward this request with the access token (using an `Authorization` header) and, if the given identity server doesn't support v2 endpoints, will fall back to v1 (which doesn't require any access tokens).
Requires: ~~#5976~~
Broke in #5971
Basically the bug is that if get_current_state_deltas returns no new updates and we then take the max pos, its possible that we miss an update that happens in between the two calls. (e.g. get_current_state_deltas looks up to stream pos 5, then an event persists and so getting the max stream pos returns 6, meaning that next time we check for things with a stream pos bigger than 6)
We want to assign unique mxids to saml users based on an incrementing
suffix. For that to work, we need to record the allocated mxid in a separate
table.
This allows support users to be created even on MAU limits via
the admin API. Support users are excluded from MAU after creation,
so it makes sense to exclude them in creation - except if the
whole host is in disabled state.

Some small fixes to `room_member.py` found while doing other PRs.
1. Add requester to the base `_remote_reject_invite` method.
2. `send_membership_event`'s docstring was out of date and took in a `remote_room_hosts` arg that was not used and no calling function provided.
Another small fixup noticed during work on a larger PR. The `origin` field of `add_display_name_to_third_party_invite` is not used and likely was just carried over from the `on_PUT` method of `FederationThirdPartyInviteExchangeServlet` which, like all other servlets, provides an `origin` argument.
Since it's not used anywhere in the handler function though, we should remove it from the function arguments.
Previously if the first registered user was a "support" or "bot" user,
when the first real user registers, the auto-join rooms were not
created.

Some of the caches on worker processes were not being correctly invalidated
when a room's state was changed in a way that did not affect the membership
list of the room.
We need to make sure we send out cache invalidations even when no memberships
are changing.

- Add boolean to skip the whitelisting check on inject
extract methods. - useful when injecting into carriers

- start_active_span_from_request instead of header
- Add boolean to decide whether to extract context

There's no point doing a raise_from here, because the exception is always
logged at warn with no stacktrace in the caller. Instead, let's try to give
better messages to reduce confusion.
In particular, this means that we won't log 'Failed to connect to remote
server' when we don't even attempt to connect to the remote server due to
blacklisting.
Get rid of the labyrinthine `recoverer_fn` code, and clean up the startup code
(it seemed to be previously inexplicably split between

Add some docstrings too.
Hopefully, this will fix a stack overflow when recovering an appservice.
The recursion here leads to a huge chain of deferred callbacks, which then
overflows the stack when the chain completes. `inlineCallbacks` makes a better
job of this if we use iteration instead.
Clean up the code a bit too, while we're there.

The emailconfig code was attempting to pull incorrect config file names. This corrects that, while also marking a difference between a config file variable that's a filepath versus a str containing HTML.
This refactors MatrixFederationAgent to move the SRV lookup into the

1. Its easier to retry different host/ports in the same way as
HostnameEndpoint.
2. We avoid SRV lookups if we have a free connection in the pool

This gives a bit of a grace period where we can attempt to refetch a
remote `well-known`, while still using the cached result if that fails.
Hopefully this will make the well-known resolution a bit more torelant
of failures, rather than it immediately treating failures as "no result"
and caching that for an hour.
* allow devices to be marked as "hidden"
This is a prerequisite for cross-signing, as it allows us to create other things
that live within the device namespace, so they can be used for signatures.
It costs both us and the remote server for us to fetch the well known
for every single request we send, so we add a minimum cache period. This
is set to 5m so that we still honour the basic premise of "refetch
frequently".
When persisting events we calculate new stream orderings up front.
Before we notify about an event all events with lower stream orderings
must have finished being persisted.
This PR moves the assignment of stream ordering till *after* calculated
the new current state and split the batch of events into separate chunks
for persistence. This means that if it takes a long time to calculate
new current state then it will not block events in other rooms being
notified about.
This should help reduce some global pauses in the events stream which
can last for tens of seconds (if not longer), caused by some
particularly expensive state resolutions.
This hopefully addresses #5407 by gracefully handling an empty but
limited TimelineBatch. We also add some logging to figure out how this
is happening.
