* tor-proto: Handle new BEGIN cells for rejected stream.Gabriela Moldovan2023-08-032-0/+101
| | | | | | | | | This updates the reactor to call the incoming stream handler even for streams for which we have a stream map entry of `EndSent`. If we've sent an END message for a stream but have not yet received an END message back from the other party, but we later receive a BEGIN from them, it is safe to assume we cam remove the stream from the stream map and handle the new incoming stream request.
* tor-proto: Clarify what we mean by "stream" in allow_stream_requests.Gabriela Moldovan2023-08-031-3/+3
|
* tor-proto: Add note about making hop_num optional.Gabriela Moldovan2023-08-031-0/+7
|
* tor-proto: Add a TODO about checking if a hop is allowed to create streams.Gabriela Moldovan2023-08-031-0/+3
|
* tor-proto: Remove unnecessary else-branch.Gabriela Moldovan2023-08-031-38/+38
| | | | | We return early if `message_closes_stream == true`, so we can get rid of the `else` to remove one level of indentation.
* tor-proto: Update the stream map if we get an END message.Gabriela Moldovan2023-08-031-1/+5
| | | | | This handles the previously not handled `message_closes_stream == true` case.
* tor-proto: Add TODO regarding allow_stream_requests corner case.Gabriela Moldovan2023-08-031-0/+24
|
* tor-proto: Remove outdated comments.Gabriela Moldovan2023-08-031-3/+0

* tor-proto: Handle RELAY_BEGIN cells if we have an incoming req handler.Gabriela Moldovan2023-08-031-0/+84

* tor-proto: Implement IncomingStream::{accept_data, request, reject}.Gabriela Moldovan2023-08-031-6/+32
|
* tor-proto: Add StreamTarget function for sending CtrlMsg::CloseStream .Gabriela Moldovan2023-08-031-0/+46
| | | | This will be used by `IncomingStream` to implement `reject()`.
* tor-proto: Add reactor control commands for accepting/closing incoming streams.Gabriela Moldovan2023-08-031-4/+62
| | | | | | | | | This adds a new `AwaitIncomingStream` control message for registering an interest in an incoming stream. This also adds a `ClosePendingStream` control message for explicitly closing a stream with a given END message (needed for implementing `IncomingStream::reject`).
* tor-proto: Add types for sharing stream request info with the reactor.Gabriela Moldovan2023-08-031-0/+49
|
* tor-proto: Add a helper for adding a stream entry with a specific stream ID.Gabriela Moldovan2023-08-032-2/+47
| | | | | | | | | This adds a new `add_ent_with_id` function for adding a new entry to the `StreamMap`. The existing `add_ent` function auto-generates a new stream ID, which is not good if we're a hidden service, as stream IDs are supposed to be chosen by the OP (client). When accepting a new stream, services, exit relays, and dir auths need to use the stream ID received in the BEGIN cell (instead of generating a new stream ID).
* tor-proto: Remove extraneous space.Gabriela Moldovan2023-08-032-2/+2
|
* tor-proto: Add constructors for pre-connected DataStreams.Gabriela Moldovan2023-08-031-2/+41
| | | | | | | | | When accepting a new stream, hidden services, exit relays and dirauths don't wait for a `CONNECTED` cell from the initiator. This commit adds constructors for building `DataStream`s and `DataCmdChecker`s that can immediately receive data cells (and don't expect to receive `CONNECTED` cells at all).
* tor-proto: Add a constructor for IncomingStream.Gabriela Moldovan2023-08-031-0/+13
|
* tor-proto: Add imports for commonly used types.Gabriela Moldovan2023-08-031-4/+4

* tor-proto: Add IncomingCmdChecker for IncomingStream.Gabriela Moldovan2023-08-032-2/+62

|
* tor-proto: Add functions for handling Shutdown and AddFakeHop messages.Gabriela Moldovan2023-07-261-42/+37
| | | | | This helps reduce code duplication, as `CtrlMsg::Shutdown` and `CtrlMsg::AddFakeHop` are now handled in multiple places.
* tor-proto: Extract first-hop creation to a separate function.Gabriela Moldovan2023-07-261-37/+11
| | | | | | I think it's safe to handle `ChanMsg::Create` separately, because there's nothing for the reactor to do until the first hop of the circuit is created (so blocking on this _should_ be alright).
* tor-proto: Create a function for handling the initial CREATE cell.Gabriela Moldovan2023-07-261-1/+89
| | | | | | This logic from `create_firsthop()` was extracted (copied) from `Reactor::run_once()`. A future commit will update `Reactor::run_once()` to use `create_firsthop()`.
* tor-circmgr: Add two possibly-needed docsrs annotationsIan Jackson2023-07-122-0/+2
| | | | | I don't know if these are needed because the rules are not documented afaict. But it seems like probably they ought to be there?

| * tor-proto conversation API: Rename to ConversationFinishedIan Jackson2023-06-301-7/+3
