Rename onion-* cargo features to hs-* in tor-* crates

2023-02-28T11:10:17Z

Fixes #756

Use CmdChecker in our stream handling code.

2023-02-17T16:52:09Z

This change makes sure that open streams and half-closed streams have the same stream-type-dependent state machines with respect to which cells are acceptable. Fixes #774. Fixes #769.

tor-proto: note implications for future HS work

2023-02-15T15:48:19Z

tor-proto: defer meta-cell parsing to the last moment.

tor-cell: Refactor relay cells to copy much less

2023-02-15T15:48:19Z

We now manipulate raw relay cell bodies as (an alias for) `Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This enables us to do much less copying. It will become more important soon, as we defer parsing relay cell bodies even longer. Related to #7. We also use SliceWriter to avoid allocating a Vec<> for every relay message we want to encode, and instead encode directly into the cell.

Rename OpenClientChan{Msg,Cell} => OpenChan{Msg,Cell}S2C

tor-proto: Do not parse forbidden commands on inbound cells.

2023-02-09T15:20:31Z

Unlike C tor, we treat unrecognized commands as reason to kill off the connection entirely. That's fine; if we need to add an unrecognized command in the future, we can use VERSIONS to negotiate it. Also, if someday we want this code to support relay channels as well, we can use some type trickery to have that work too.

tor-cell: Rename RelayMsg and RelayCell-related types.

2023-02-07T21:03:14Z

Thanks to rust-analyzer for making this simple.

tor-cell: Rename ChanMsg and ChanCell-related types.

2023-02-07T21:03:14Z

tor-cell: Change all variants of RelayMsg to have a body.

2023-02-07T21:03:14Z

Previously, there were some unit variants, but that makes things quite awkward for #525.
