Description

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.
