| * | Refactor/simplify HopSettings constructionNick Mathewson2025-07-232-60/+108
| | | | | | | | | | | | | | | | | | | | | We now take an enum describing whether we are doing no negotiation, HsV3 negotiation, or full negotiation. This lets us do away with the notions of default relay crypto, and of declaring post-facto that no negotiation has occurred.
| * | Rename and invert the sense of requires_stream_level_sendmes.Nick Mathewson2025-07-232-5/+9
| | | | | | | | | | | | | | | Instead call it compatible_with_cgo, which is what we actually care about in this context.
| * | proto: Send extensions as appropriate to negotiate CGO.Nick Mathewson2025-07-233-1/+54
| | | | | | | | | | | | Let's see if it works!

| * | proto: Take format+crypto settings from HopSettingsNick Mathewson2025-07-237-54/+58
| | | | | | | | | | | | | | | Since these will be negotiated (or determined as part of negotiation) they belong in HopSettings.

| * | tor-proto: replace `DataReader`Steven Engler2025-07-172-44/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `DataReader` -> `DataReaderInner` `DataReaderNew` -> `DataReader` This means that the `DataReader` now supports XON/XOFF flow control using the `XonXoffReader`. This means that it can receive requests for a new drain rate from the reactor, and can send the new drain rate to the reactor once there is no more stream data queued.
| * | tor-proto: add `DataReaderNew`Steven Engler2025-07-173-5/+75
| | | | | | | | | | | | This will later become `DataReader`.
| * | tor-proto: add `StreamReceiver::is_empty()`Steven Engler2025-07-171-1/+39

| * | tor-proto: add the `XonXoffReader` and connect it to the reactorSteven Engler2025-07-1711-15/+267
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The idea here is that the reactor builds an `XonXoffReaderCtrl` for the new stream, and the `XonXoffReaderCtrl` can receive notifications from the reactor's `StreamFlowControl`. The `XonXoffReaderCtrl` can be combined with any `AsyncRead` to build a `XonXoffReader`, essentially wrapping the `AsyncRead` with a type that handles XON/XOFF flow control. Essentially, the reactor gives you a type that allows you to add XON/XOFF flow control support to any `AsyncRead`. We will add this `XonXoffReader` to the `DataReader` in a future commit.
| * | tor-proto: add plumbing for sending XONSteven Engler2025-07-176-5/+171
| | | | | | | | | | | | | | | Nothing actually causes an XON to be sent yet. But this adds the code so that anything holding the `StreamTarget` can request to send an XON.

| * | maint: Avoid x-prefix in comparisons.Gabriela Moldovan2025-07-174-4/+4
|/ / | | | | | | | | | | | | This applies the fixes suggested by shellcheck (the x-prefixes were causing the `shellcheck` job to fail; see [SC2268]). [SC2268]: https://www.shellcheck.net/wiki/SC2268

| * | tor-proto: add dedicated types for the incoming stream queueSteven Engler2025-07-1610-24/+275
| | | | | | | | | | | | | | | XON/XOFF flow control will want to know how many data bytes are queued on a stream, so the new types track that.
| * | tor-cell: change `UnparsedRelayMsg::data_len`Steven Engler2025-07-153-9/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | It now performs some validation and can return a `Result`. We perform validation here since different cell formats may have different maximum data lengths in the future, and `UnparsedRelayMsg` doesn't expose the cell format so it's difficult to perform this validation at a higher layer.
| * | tor-proto: combine some objects into a `StreamComponents`Steven Engler2025-07-152-28/+64
| | | | | | | | | | | | | | | | | | As we continue adding more functionality to streams like flow control, we'll have more objects to pass around. This tries to group them together.
| * | tor-proto: rename `StreamSendFlowControl` and related changesSteven Engler2025-07-155-46/+47
| | | | | | | | | | | | | | | | | | | | | | | | The plan is to use `StreamSendFlowControl` (now `StreamFlowControl`) for both outgoing and incoming directions, so a name change is needed. This also updates some comments, and renames some related struct fields that have the word "send" in them.
| * | tor-proto: adjust `CtrlMsg::SendSendme` and renameSteven Engler2025-07-153-60/+80
| | | | | | | | | | | | | | | | | | | | | | | | This allows us to extend the command to implement different flow control methods. We could add new command variants for new flow control methods instead, but I think it makes sense to have them be a single command as they will always have a stream ID / hop location in common. This also helps us keep the flow control logic in one place.
| * | tor-cell: remove `flowctl-cc` feature and make XON/XOFF cells stableSteven Engler2025-07-156-13/+3
| | | | | | | | | | | | | | | I don't see any further changes being needed for these types, and it simplifies a lot of future code in tor-proto that uses these types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `Ord` impl of `OooRelayMsg` already "reverses" the seqno comparison, which means previously we were double-reversing it (leading to the ooo cell heap logic being broken in cases where its size was > 1). Caught by the new conflux switch handling tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The two mock exit legs will use this channel to notify each other of the receipt of BEGIN cells. This will enable us to extend the tests to support writing cells to the stream (but only after the stream is opened).
