Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`). This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world. --- changelog.d/15913.feature | 1 + .../configuration/config_documentation.md | 33 +- docs/workers.md | 24 ++ synapse/api/errors.py | 7 + synapse/app/_base.py | 2 + synapse/app/generic_worker.py | 1 + synapse/app/homeserver.py | 1 + synapse/config/workers.py | 45 ++- synapse/http/client.py | 7 +- synapse/http/connectproxyclient.py | 20 +- synapse/http/matrixfederationclient.py | 142 ++++++++- synapse/http/proxy.py | 283 +++++++++++++++++ synapse/http/proxyagent.py | 141 ++++++++- synapse/http/server.py | 55 ++-- synapse/http/site.py | 27 +- tests/app/test_openid_listener.py | 8 +- tests/handlers/test_device.py | 3 +- tests/handlers/test_federation.py | 2 +- tests/handlers/test_presence.py | 1 - tests/handlers/test_typing.py | 10 + tests/http/test_matrixfederationclient.py | 284 +++++++++++++++++- tests/http/test_proxy.py | 53 ++++ tests/http/test_proxyagent.py | 4 +- tests/replication/_base.py | 3 +- .../test_federation_sender_shard.py | 22 +- tests/rest/client/test_presence.py | 1 - tests/rest/client/test_rooms.py | 2 - tests/storage/test_e2e_room_keys.py | 2 +- tests/storage/test_purge.py | 2 +- tests/storage/test_rollback_worker.py | 4 +- tests/test_server.py | 33 +- tests/unittest.py | 1 + 32 files changed, 1128 insertions(+), 96 deletions(-) create mode 100644 changelog.d/15913.feature create mode 100644 synapse/http/proxy.py create mode 100644 tests/http/test_proxy.py diff --git a/changelog.d/15913.feature b/changelog.d/15913.feature new file mode 100644 index 0000000000..0d77fae2dc --- /dev/null +++ b/changelog.d/15913.feature @@ -0,0 +1 @@ +Allow configuring the set of workers to proxy outbound federation traffic through via `outbound_federation_restricted_to`. diff --git a/docs/usage/configuration/config_documentation.md b/docs/usage/configuration/config_documentation.md index 22cd1772dc..4e6fcd085a 100644 --- a/docs/usage/configuration/config_documentation.md +++ b/docs/usage/configuration/config_documentation.md @@ -3960,13 +3960,14 @@ federation_sender_instances: --- ### `instance_map` -When using workers this should be a map from [`worker_name`](#worker_name) to the -HTTP replication listener of the worker, if configured, and to the main process. -Each worker declared under [`stream_writers`](../../workers.md#stream-writers) needs -a HTTP replication listener, and that listener should be included in the `instance_map`. -The main process also needs an entry on the `instance_map`, and it should be listed under -`main` **if even one other worker exists**.
