#22688: HSDir3s should refuse direct client descriptor uploads and downloads,
even
if encrypted
-------------------------+-------------------------------------------------
Reporter: teor | Owner:
Type: defect | Status: new
Priority: Medium | Milestone: Tor: 0.3.1.x-final
Component: Core | Version: Tor: unspecified

-------------------------+-------------------------------------------------
handle_post_hs_descriptor and handle_get_hs_descriptor_v3 should check
that the connection is:
* encrypted, and
* not from a client (channel_is_client in 0.3.1.1-alpha and later
correctly identifies unauthenticated peers, which are clients and
bridges).
For extra safety, we can check if the circuit is from a relay.
