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: 'XEP-0273: Stanza Interception and Filtering Technology' ... Introduction ============ [SIFT][XEP-0273] is a technology to allow clients to filter incoming traffic on the server. This helps save bandwidth, etc. Compatibility ============= ----- ------- 0.7 Works ----- ------- Quirks ====== This implementation is a work in progress. - Stanzas to full JIDs get sifted correctly - Stanzas to bare JIDs are currently allowed/disallowed for all resources as a whole, and not for individual resources - Presence is only sent to available resources, and probes are not sent for unavailable reasources - This module currently does not interact with offline messages (filtered messages are dropped with an error reply) - Not tested with privacy lists
