rpc-client-core: Always re-encode requests and responses, and preserve unrecognized struct fields. (!2312) · Merge requests · The Tor Project / Core / Arti

Nick Mathewson requested to merge nickm/arti:rpc-reencoding into main Aug 04, 2024

We want to preserve unrecognized struct fields to keep arti-rpc-client-core compatible with future RPC protocol updates.

We want to ensure that everything is re-encoded to limit any opportunities for security bugs (or other bugs) resulting from different interpretations of dubious JSON from arti, arti-rpc-client-core, and the applications. (See #1491 (closed) for discussion on this.)

Closes #1491 (closed).
