.. _version_history_1.31.0: 1.31.0 (July 19, 2024) ======================= Incompatible behavior changes ----------------------------- *Changes that are expected to cause an incompatibility if applicable; deployment changes are likely required* * **composite_filter**: Adding support for :ref:`sample_percent <envoy_v3_api_field_extensions.filters.http.composite.v3.ExecuteFilterAction.sample_percent>`. It specifies the probability of the action execution. If not specified, it is 100%. * **ext_proc**: Adding support for :ref:`route_cache_action <envoy_v3_api_field_extensions.filters.http.ext_proc.v3.ExternalProcessor.route_cache_action>`. It specifies the route action to be taken when an external processor response is received in response to request headers. * **golang**: Move ``Continue``, ``SendLocalReply`` and ``RecoverPanic`` from ``FilterCallbackHandler`` to ``DecoderFilterCallbacks`` and ``EncoderFilterCallbacks``, to support full-duplex processing. * **http2**: Changes the default value of ``envoy.reloadable_features.http2_use_oghttp2`` to ``true``. This changes the codec used for HTTP/2 requests and responses. This behavior can be reverted by setting the feature to ``false``. * **http2**: Passes HTTP/2 ``DATA`` frames through a different codec API. This behavior can be temporarily disabled by setting the runtime feature ``envoy.reloadable_features.http2_use_visitor_for_data`` to ``false``. * **http3**: Added a happy eyeballs feature to HTTP/3 upstream, where it assuming happy eyeballs sorting results in alternating address families will attempt the first v4 and v6 address before giving up on HTTP/3. This change can be reverted by setting ``envoy.reloadable_features.http3_happy_eyeballs`` to ``false``. * **local_ratelimit**: Updated the token bucket implementation to use non-timer based token bucket. The tokens will be refilled when the token bucket is accessed and no dependency on the timer. This behavior can be temporarily reverted by setting the runtime guard ``envoy.reloadable_features.no_timer_based_rate_limit_token_bucket`` to ``false``. * **proxy_protocol**: Populate typed metadata by default in proxy protocol listener. Typed metadata can be consumed as :ref:`TlvsMetadata type <envoy_v3_api_msg_data.core.v3.TlvsMetadata>`. This change can be temporarily disabled by setting the runtime flag ``envoy.reloadable_features.use_typed_metadata_in_proxy_protocol_listener`` to ``false``. * **runtime**: Rejecting invalid YAML. This has been an ``ENVOY_BUG`` linked to https://github.com/envoyproxy/envoy/issues/27434 for over a year with no hard-blockers so should be Ok. This behavior can be temporarily disabled by setting the runtime feature ``envoy.reloadable_features.reject_invalid_yaml`` to ``false`` but the runtime guard must be parsed before any invalid YAML. * **thread_local**: Changes the behavior of the ``SlotImpl`` class destructor. With this change the destructor can be called on any thread. This behavior can be reverted by setting the runtime flag ``envoy.reloadable_features.allow_slot_destroy_on_worker_threads`` to ``false``. * **tracing/datadog**: Disabled remote configuration by default. To enable this feature, use the :ref:`remote_config <envoy_v3_api_field_config.trace.v3.DatadogConfig.remote_config>` field. Minor behavior changes ---------------------- *Changes that may cause incompatibilities for some users, but should not for most* * **access_log**: The ``%CEL%`` formatter supports call functions. * **access_log**: The upstream connection address, rather than the upstream host address, will be used for the ``%UPSTREAM_REMOTE_ADDRESS%``, ``%UPSTREAM_REMOTE_PORT%`` and ``%UPSTREAM_REMOTE_ADDRESS_WITHOUT_PORT%`` access log format specifiers. This behavior can be reverted by setting the runtime guard ``envoy.reloadable_features.upstream_remote_address_use_connection`` to ``false``. * **config**: In xDS configuration, the :ref:`AUTO <envoy_v3_api_enum_value_config.core.v3.ApiVersion.AUTO>` value now means :ref:`V3 <envoy_v3_api_enum_value_config.core.v3.ApiVersion.V3>`. :ref:`AUTO <envoy_v3_api_enum_value_config.core.v3.ApiVersion.AUTO>` is the default value of the enum, so this field may be omitted from all configurations now. * **config**: Stricter validation of a ``google.protobuf.Duration`` field in a config, rejecting invalid values (where the number of years is over 292). This can be temporarily reverted by setting runtime guard ``envoy.reloadable_features.strict_duration_validation`` to ``false``. * **custom response filter**: Prevent the redirect policy from sending ``100`` as the overridden response code as the custom response must be complete. * **dfp**: Changed dynamic forward proxy so local reply errors include DNS resolution details. This behavior can be temporarily disabled by setting the runtime feature ``envoy.reloadable_features.dns_details`` to ``false``. * **dns**: Changes the behavior of the ``getaddrinfo`` DNS resolver so that it treats ``EAI_NODATA`` and ``EAI_NONAME`` as successful queries with empty results, instead of as DNS failures. This change brings the ``getaddrinfo`` behavior in-line with the c-ares resolver behavior. This behavior can be reverted by setting the runtime guard ``envoy.reloadable_features.dns_nodata_noname_is_success`` to ``false``. * **ext_proc**: Timeout errors in external processor now returns ``504 Gateway Timeout`` to downstream clients. The previous behavior was returning ``500 Internal Server Error``. * **filters**: Set ``WWW-Authenticate`` header for ``401`` responses from the Basic Auth filter. * **gcp_authn**: Use the fixed URL format instead of one from the configuration. This behavior can be disabled by setting runtime flag ``envoy.reloadable_features.gcp_authn_use_fixed_url`` to false. * **grpc**: Changes in ``AsyncStreamImpl`` and ``GoogleAsyncStreamImpl`` now propagate tracing context headers in bidirectional streams when using :ref:`Envoy gRPC client <envoy_v3_api_field_config.core.v3.GrpcService.envoy_grpc>` or :ref:`Google C++ gRPC client <envoy_v3_api_field_config.core.v3.GrpcService.google_grpc>`. Previously, tracing context headers were not being set when calling external services such as ext_proc. * **hashing**: Change murmurHash2 hashing on big endian platforms to generate the same values as little endian platforms. * **http**: Changing HTTP/2 semi-colon prefixed headers to being sanitized by Envoy code rather than nghttp2. Should be a functional no-op but guarded by ``envoy.reloadable_features.sanitize_http2_headers_without_nghttp2``. * **http**: Changing header validation checks in the substitution format utility and CEL code to do RFC-compliant header validation. This behavior can be reverted by setting the runtime guard ``envoy.reloadable_features.consistent_header_validation`` to ``false``. * **http**: Envoy will now proxy ``104`` headers from upstream, though as with ``100`` only the first 1xx response headers will be sent. ``104`` headers are designated by IETF's draft-ietf-httpbis-resumable-upload RFC. This behavioral can be temporarily reverted by setting runtime guard ``envoy.reloadable_features.proxy_104`` to ``false``. * **http**: Fixed host header changes for shadow requests to properly handle ipv6 addresses. * **http**: Reject messages with chunked transfer encoding with chunk extension containing ``CR`` not followed by ``LF``. This can be temporarily reverted by setting runtime guard ``envoy.reloadable_features.http1_balsa_disallow_lone_cr_in_chunk_extension`` to ``false``. * **http**: Removed runtime guard ``envoy.reloadable_features.refresh_rtt_after_request`` and legacy code path. * **jwt_authn**: Changes the behavior of the :ref:`forward <envoy_v3_api_field_extensions.filters.http.jwt_authn.v3.JwtProvider.forward>` config. Previously, the config only removes JWT if set in headers. With this addition, the config can also be used to remove JWT set in query parameters. This behavior can be reverted by setting the runtime guard ``envoy.reloadable_features.jwt_authn_remove_jwt_from_query_params`` to ``false``. * **jwt_authn**: jwt_authn now validates provider URIs. If the validation is too strict it can temporarily be disabled by setting the runtime guard ``envoy.reloadable_features.jwt_authn_validate_uri`` to ``false``. * **quic**: A change in QUICHE has renamed all flags formerly of the form ``quic_reloadable_flag_...`` to ``quiche_reloadable_flag_...``. Likewise, for ``quic_restart_flag_...``, now ``quiche_restart_flag_...``. Consequently, all Envoy flags of those forms with an ``envoy_quic_...`` prefix have been similarly renamed to ``envoy_quiche_...``. * **quic**: Cache source/destination address instances in a LRU cache for packet read to improve performance. This behavior can be reverted by setting the runtime guard ``envoy.reloadable_features.quic_upstream_socket_use_address_cache_for_read`` to ``false``. * **quic**: When a quic connection socket is created, the socket's detected transport protocol will be set to ``quic``. * **statistics**: Hot restart statistics like ``hot_restart_epoch`` are only set when hot restart is enabled. * **tracers**: Set status code for OpenTelemetry tracers (previously unset). * **udp**: Change GRO read buffer to 64kB to avoid ``MSG_TRUNC``. And change the way to limit the number of packets processed per event loop to work with GRO. This behavior can be reverted by setting runtime guard ``envoy.reloadable_features.udp_socket_apply_aggregated_read_limit`` to ``false``. * **xds**: Updated xDS-TP path naming to better comply with RFC-3986. Encoded resource paths can now include an a colon ``:``, instead of ``%3A``. This behavior can be reverted by setting the runtime flag ``envoy.reloadable_features.xdstp_path_avoid_colon_encoding`` to ``false``. Bug fixes --------- *Changes expected to improve the state of the world and are unlikely to have negative effects* * **admin**: Fixed missing :ref:`additional addresses <envoy_v3_api_msg_config.endpoint.v3.Endpoint.AdditionalAddress>` for :ref:`LbEndpoint <envoy_v3_api_field_config.endpoint.v3.LbEndpoint.endpoint>` in config dump. * **admission control**: Fixed the thread-local controller's average RPS calculation to be calculated over the full lookback window. Previously, the controller would calculate the average RPS over the amount of time elapsed since the oldest valid request sample. This change brings the behavior in line with the documentation. * **async http client**: Added one option to disable the response body buffering for mirror request. Also introduced a 32MB cap for the response buffer, which can be changed by the runtime flag ``http.async_response_buffer_limit`` based on the product needs. * **cares**: Upgraded c-ares library to 1.20.1 and added fix to c-ares DNS implementation to additionally check for ``ARES_EREFUSED``, ``ARES_ESERVFAIL`` and ``ARES_ENOTIMP`` status. Without this fix, ``DestroyChannelOnRefused`` and ``CustomResolverValidAfterChannelDestruction`` unit test will break. * **datadog**: Bumped the version of datadog to resolve a crashing bug in earlier versions of the library. * **decompression**: Fixed a bug where Envoy will go into an endless loop when using the brotli decompressor. If the input stream has redundant data, the decompressor will loop forever. * **ext_authz**: Added field :ref:`validate_mutations <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.ExtAuthz.validate_mutations>`, which, when set to ``true``, adds header and query parameter mutation validation to the HTTP ext_authz filter. If an authz response contains invalid mutations, the filter responds to the downstream request with HTTP ``500 Internal Server Error``. If you use ext_authz with an untrusted side stream, it's recommended you set this to ``true``. * **ext_authz**: Handle ``append_action`` from :ref:`external authorization service <envoy_v3_api_msg_service.auth.v3.CheckResponse>` that was ignored. * **ext_authz**: Set the SNI value from the requested server name if it isn't available on the connection/socket. This applies when ``include_tls_session`` is ``true``. The requested server name is set on a connection when filters such as the TLS inspector are used. * **ext_authz**: Validate http service :ref:`path_prefix <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.HttpService.path_prefix>`, Valid HTTP service ``path_prefix`` configuration must start with ``/``. * **http**: Fix BalsaParser resetting state too early, guarded by ``envoy.reloadable_features.http1_balsa_delay_reset`` which defaults to ``true``. * **http**: Fix a crash when reloading the HTTP Connection Manager via ECDS. * **http**: Fixed a bug where additional :ref:`cookie attributes <envoy_v3_api_msg_config.route.v3.RouteAction.HashPolicy.cookie>` are not sent properly to clients. * **local_ratelimit**: Fixed a bug where the local rate limit filter would crash when the :ref:`enable_x_ratelimit_headers <envoy_v3_api_msg_extensions.filters.http.ratelimit.v3.RateLimit>` is set to ``DRAFT_VERSION_03`` and a send local reply is triggered before the rate limit filter is executed. * **lua**: Fixed a bug where the user data will reference a dangling pointer to the Lua state and cause a crash. * **oauth**: The ID token cookie now expires at the same time the id token itself expires, instead of when the access token expires. * **oauth2**: Fixed a bug that would cause Envoy to crash when receiving an Oauth callback while the Oauth upstream is unhealthy (e.g. due to DNS issues). * **outlier detection**: Fixed :ref:`successful_active_health_check_uneject_host <envoy_v3_api_field_config.cluster.v3.OutlierDetection.successful_active_health_check_uneject_host>`. Before, a failed health check could uneject the host if the ``FAILED_ACTIVE_HC`` health flag had not been set. * **quic**: Applied 2 QUICHE patches for crash bugs in ``QuicSpdyStream`` ``OnDataAvailable()`` and ``OnInitialHeaderComplete()``. * **quic**: Fixed crash bug when QUIC downstream stream was read closed and then timed out. * **tls**: Fix a ``RELEASE_ASSERT`` when using :ref:`auto_sni <envoy_v3_api_field_config.core.v3.UpstreamHttpProtocolOptions.auto_sni>` if the downstream request ``:authority`` was longer than 255 characters. * **tracing**: Added support to configure a static config resource detector for the OpenTelemetry tracer. * **tracing**: Fix an issue where span id is missing from OpenTelemetry access log entries. * **udp**: Fixed a bug that would cause Envoy to crash when updates to a pre-existing cluster were made (e.g. ``HostSet`` changes). * **websocket**: Only ``101`` is considered a successful response for websocket handshake for HTTP/1.1, and Envoy as a proxy will proxy the response header from upstream to downstream and then close the request if other status is received. This behavior can be reverted by ``envoy_reloadable_features_check_switch_protocol_websocket_handshake``.

New features ------------ * **access_log**: Added support for :ref:`%UPSTREAM_HOST_NAME% <config_access_log_format_upstream_host_name>` for the upstream host identifier. * **access_log**: added new ``access_log`` command operators to retrieve upstream connection information change: ``%UPSTREAM_PEER_URI_SAN%``, ``%UPSTREAM_PEER_IP_SAN%``, ``%UPSTREAM_PEER_DNS_SAN%``, ``%UPSTREAM_LOCAL_URI_SAN%``, ``%UPSTREAM_LOCAL_DNS_SAN%``, ``%UPSTREAM_LOCAL_IP_SAN%``. * **access_loggers**: Added ``TRACE_ID`` :ref:`access log formatter <config_access_log_format>`. * **aws_lambda**: The ``aws_lambda`` filter now supports the :ref:`credentials <envoy_v3_api_field_extensions.filters.http.aws_lambda.v3.Config.credentials>` parameter. This enables setting AWS credentials from the filter configuration. * **cares**: Added :ref:`udp_max_queries<envoy_v3_api_field_extensions.network.dns_resolver.cares.v3.CaresDnsResolverConfig.udp_max_queries>` option to limit the number of UDP queries. * **dns_filter**: Added support for wildcard resolution in :ref:`inline_dns_table <envoy_v3_api_field_extensions.filters.udp.dns_filter.v3.DnsFilterConfig.ServerContextConfig.inline_dns_table>` when DNS filter is working in server mode. * **ext_authz**: Added :ref:`decoder_header_mutation_rules <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.ExtAuthz.decoder_header_mutation_rules>` which allows you to configure what decoder header mutations are allowed from the ext_authz service as well as whether to fail the downstream request if disallowed mutations are requested. * **ext_authz**: Added :ref:`enable_dynamic_metadata_ingestion <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.ExtAuthz.enable_dynamic_metadata_ingestion>`, which allows ext_authz to be configured to ignore dynamic metadata in ext_authz responses. * **ext_authz**: Added :ref:`disallowed_headers <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.ExtAuthz.disallowed_headers>` to specify headers that should never be sent to the external authentication service. Overrides :ref:`allowed_headers <envoy_v3_api_field_extensions.filters.http.ext_authz.v3.ExtAuthz.allowed_headers>` if a header matches both. * **ext_proc**: Added support for observability mode which deprecates ``async_mode``. If enabled, each part of the HTTP request or response specified by ``ProcessingMode`` is sent without waiting for the response from the ext_proc service. It is "Send and Go" mode that can be used by external processor to observe Envoy data and status. * **formatter**: Added formatters for :ref:`METADATA(VIRTUAL_HOST)<envoy_v3_api_msg_extensions.formatter.metadata.v3.Metadata>`. * **grpc**: Added support for flow control in Envoy gRPC side stream. This behavior can be disabled by setting the runtime flag ``envoy.reloadable_features.grpc_side_stream_flow_control`` to ``false``. * **healthcheck**: Added support to healthcheck with ProxyProtocol in TCP Healthcheck by setting :ref:`health_check_config <envoy_v3_api_field_config.core.v3.HealthCheck.TcpHealthCheck.proxy_protocol_config>`. * **hot_restart**: Added new command-line flag :option:`--skip-hot-restart-parent-stats`. * **http**: Added :ref:`disable_shadow_host_suffix_append <envoy_v3_api_field_config.route.v3.RouteAction.RequestMirrorPolicy.disable_shadow_host_suffix_append>` in :ref:`request_mirror_policies <envoy_v3_api_field_config.route.v3.RouteAction.request_mirror_policies>` for disabling appending of the ``-shadow`` suffix to the shadowed host/authority header. * **http**: Added field :ref:`match_upstream <envoy_v3_api_field_config.core.v3.SchemeHeaderTransformation.match_upstream>`, which, when set to ``true``, will set the downstream request ``:scheme`` to match the upstream transport protocol. * **jwt_authn**: Added :ref:`strip_failure_response <envoy_v3_api_field_extensions.filters.http.jwt_authn.v3.JwtAuthentication.strip_failure_response>` to allow stripping the failure response details from the JWT authentication filter. * **listener**: Added :ref:`bypass_overload_manager <envoy_v3_api_field_config.listener.v3.Listener.bypass_overload_manager>` to bypass the overload manager for a listener. When set to ``true``, the listener will not be subject to overload protection. * **local_rate_limit**: Added support for :ref:`local cluster rate limit <envoy_v3_api_field_extensions.filters.http.local_ratelimit.v3.LocalRateLimit.local_cluster_rate_limit>`. If set, the token buckets of the local rate limit will be shared across all the Envoy instances in the local cluster. * **matching**: Added :ref:`Filter State Input <envoy_v3_api_msg_extensions.matching.common_inputs.network.v3.FilterStateInput>` for matching HTTP input based on filter state objects. * **oauth**: Added :ref:`disable_id_token_set_cookie <envoy_v3_api_field_extensions.filters.http.oauth2.v3.OAuth2Config.disable_id_token_set_cookie>` to disable setting the ID Token cookie. * **open_telemetry**: Added :ref:`formatters <envoy_v3_api_field_extensions.access_loggers.open_telemetry.v3.OpenTelemetryAccessLogConfig.formatters>` configuration to support extension formatter for the OpenTelemetry logger. * **open_telemetry**: Added :ref:`stat_prefix <envoy_v3_api_field_extensions.access_loggers.open_telemetry.v3.OpenTelemetryAccessLogConfig.stat_prefix>` configuration to support additional stat prefix for the OpenTelemetry logger. * **outlier detection**: Added :ref:`always_eject_one_host<envoy_v3_api_field_config.cluster.v3.OutlierDetection.always_eject_one_host>` to optionally override the :ref:`max_ejection_percent<envoy_v3_api_field_config.cluster.v3.OutlierDetection.max_ejection_percent>`. * **proxy_protocol**: Added field :ref:`stat_prefix <envoy_v3_api_field_extensions.filters.listener.proxy_protocol.v3.ProxyProtocol.stat_prefix>` to the proxy protocol listener filter configuration, allowing for differentiating statistics when multiple proxy protocol listener filters are configured. * **quic**: Added :ref:`DataSourceServerPreferredAddressConfig <envoy_v3_api_msg_extensions.quic.server_preferred_address.v3.DataSourceServerPreferredAddressConfig>` for cases when the control plane does not know the correct configuration for the server preferred address. * **quic**: Added new interface to ``QuicListenerFilter`` that is called on receiving the first packet. * **quic**: Added support for QUIC server preferred address when there is a DNAT between the client and Envoy. See :ref:`new config <envoy_v3_api_field_extensions.quic.server_preferred_address.v3.FixedServerPreferredAddressConfig.AddressFamilyConfig.dnat_address>`. * **quic**: QUIC stream reset error code will be added to transport failure reason. This behavior can be reverted by setting the runtime flag ``envoy.reloadable_features.report_stream_reset_error_code`` to ``false``. * **rbac**: The RBAC filter will now log the enforced rule to the dynamic metadata field ``enforced_effective_policy_id`` and the result to the dynamic metadata field ``enforced_engine_result``. These are only populated if a non-shadow engine exists. * **redis**: Added support for ``xack``, ``xadd``, ``xautoclaim``, ``xclaim``, ``xdel``, ``xlen``, ``xpending``, ``xrange``, ``xrevrange``, ``xtrim``. * **redis**: Added support for `inline commands <https://redis.io/docs/reference/protocol-spec/#inline-commands>`_. * **redis**: Added support for all Bloom 1.0.0 commands. * **retry**: Added :ref:`reset-before-request retry policy <config_http_filters_router_x-envoy-retry-on>`. * **routing**: Added support in :ref:`file datasource <envoy_v3_api_field_config.route.v3.DirectResponseAction.body>` implementation to listen to file changes and dynamically update the response when :ref:`watched_directory <envoy_v3_api_field_config.core.v3.datasource.watched_directory>` is configured in :ref:`DataSource <envoy_v3_api_msg_config.core.v3.datasource>`. * **thrift**: Added implementation of :ref:`thrift to metadata <envoy_v3_api_msg_extensions.filters.http.thrift_to_metadata.v3.ThriftToMetadata>` HTTP filter. * **tls**: Added support to match against ``OtherName`` SAN-type under :ref:`match_typed_subject_alt_names <envoy_v3_api_field_extensions.transport_sockets.tls.v3.CertificateValidationContext.match_typed_subject_alt_names>`. An additional field ``oid`` is added to :ref:`SubjectAltNameMatcher <envoy_v3_api_msg_extensions.transport_sockets.tls.v3.SubjectAltNameMatcher>` to support this change. * **upstream**: Added a new field to ``LocalityLbEndpoints``, :ref:`LocalityLbEndpoints.Metadata <envoy_v3_api_field_config.endpoint.v3.LocalityLbEndpoints.metadata>`, that may be used for transport socket matching groups of endpoints. * **wasm**: Update WASM filter to support use as an upstream filter. Deprecated ---------- * **tracing**: Disable OpenCensus by default, as it is `no longer supported/maintained upstream <https://opentelemetry.io/blog/2023/sunsetting-opencensus/>`_. This extension can be replaced with the OpenTelemetry tracer and collector.
