What type of PR is this?
Following the discussion at KubeCon NA : https://docs.google.com/document/d/1PS5xLA0IDbj6McHIXXhShn51Zq37WvuistaidBPeHoE/edit?tab=t.0
Scope and Motivation
This API will allow users to define which attributes are sent to the external processor as context for requests/responses.
Attributes provide HTTP extensions with additional context (e.g. TCP, TLS and XDS attributes) that can be relevant inputs for the extension logic.
Comparison to other extension options
Many Envoy extensions are inherently capable of interaction with context attributes:
For out-of-process extensions like ext-proc, Envoy must be explicitly configured to allow access to attributes and and define the scope of access. With the increase in ext-proc use cases, such as the llm-instance-gateway, envoy-ai-gateway and externally-deployed WAFs, there is a greater need to provide Connection/Stream context.
Security Considerations
Most attributes are scoped to the current connection or stream by their prefix (
connection.*,request.*,response.*), with the exception ofxds.*attributes such asxds.listener_metadata,xds.upstream_host_metadata,xds.nodeand generic metadata and filter state access attributes.Related Work
