mod_http_oauth2: Implement stateless dynamic client registration
Replaces previous explicit registration that required either the
additional module mod_adhoc_oauth2_client or manually editing the
database. That method was enough to have something to test with, but
would not probably not scale easily.
Dynamic client registration allows creating clients on the fly, which
may be even easier in theory.
In order to not allow basically unauthenticated writes to the database,
we implement a stateless model here.
per_host_key := HMAC(config -> oauth2_registration_key, hostname)
client_id := JWT { client metadata } signed with per_host_key
client_secret := HMAC(per_host_key, client_id)
This should ensure everything we need to know is part of the client_id,
allowing redirects etc to be validated, and the client_secret can be
validated with only the client_id and the per_host_key.
A nonce injected into the client_id JWT should ensure nobody can submit
the same client metadata and retrieve the same client_secret

--- labels: - Stage-Alpha summary: Compatibility layer for Prosody's future roles API --- Introduction ============ This module provides compatibility with Prosody's new role and permissions system. It aims to run on Prosody 0.11 and 0.12, providing a limited version of the new API backed by is_admin() (which is not going to be present in trunk and future Prosody versions). It is designed for use by modules which want to be compatible with Prosody versions with and without the new permissions API. Configuration ============= There is no configuration. Usage (for developers) ====================== If you are a module developer, and want your module to work with Prosody trunk and future releases, you should avoid the `usermanager.is_admin()` function. Instead, depend on this module: ``` module:depends("compat_roles") ``` Then use `module:may()` instead: ``` if module:may(":do-something") then -- Blah end ``` For more information on the new role/permissions API, check Prosody's developer documentation at https://prosody.im/doc/developers/permissions Compatibility ============= Requires Prosody 0.11 or 0.12.
