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

summary: 'Privacy lists (XEP-0016) support'
...

Introduction
------------

Privacy lists are a flexible method for blocking communications.

Originally known as mod\_privacy and bundled with Prosody, this module
is being phased out in favour of the newer simpler blocking (XEP-0191)
protocol, implemented in [mod\_blocklist][doc:modules:mod_blocklist].

Configuration
-------------

None. Each user can specify their privacy lists using their client (if
it supports XEP-0016).

Compatibility
