This PR introduces a way to implement Attribute Based Access Control (ABAC) for the Llama Stack server. The rough design is: - https://github.com/meta-llama/llama-stack/pull/1626 added a way for the Llama Stack server to query an authenticator - We build upon that and expect "access attributes" as part of the response. These attributes indicate the scopes available for the request. - We use these attributes to perform access control for registered resources as well as for constructing the default access control policies for newly created resources. - By default, if you support authentication but don't return access attributes, we will add a unique namespace pointing to the API_KEY. That way, all resources by default will be scoped to API_KEYs. An important aspect of this design is that Llama Stack stays out of the business of credential management or the CRUD for attributes. How you manage your namespaces or projects is entirely up to you. The design only implements access control checks for the metadata / book-keeping information that the Stack tracks. ### Limitations - Currently, read vs. write vs. admin permissions aren't made explicit, but this can be easily extended by adding appropriate attributes to the `AccessAttributes` data structure. - This design does not apply to agent instances since they are not considered resources the Stack knows about. Agent instances are completely within the scope of the Agents API provider. ### Test Plan Added unit tests, existing integration tests |
