* | | tor-config: Add ExplicitOrAuto helper.Gabriela Moldovan2024-06-031-2/+97
| | | | | | | | | | | | | | | | | | | | | | | | This will be used for the `vanguard.mode` config option. The `VanguardMode` corresponding to the `"auto"` variant will depend on whether the `vanguards` feature is enabled: if the feature is enabled, it is mapped to `VanguardMode::Lite`, and `VanguardMode::Disabled` otherwise.
* | | tor-guardmgr: Unconditionally define VanguardConfig.Gabriela Moldovan2024-06-037-33/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | We want to export the `VanguardConfig` even if the `vanguards` feature is disabled (we will need to unconditionally include it in the arti config). Note that if `vanguards` are disabled, the `VanguardMode` from the `VanguardConfig` can only be `Dsiabled`.
* | | arti-client: Remove unnecessary VanguardConfig pub use.Gabriela Moldovan2024-06-031-6/+0
| | | | | | | | | | | | | | | | | | | | | This is already exported via the `pub mod vanguards` module, so there is no need to export it from the top-level too. This *is* a breaking change, but the downstream fix is trivial (and the type should never have been exported directly from `arti_client::config` in the first place).

| * | | tor-keymgr: Regenerate the test keys.Gabriela Moldovan2024-05-1512-51/+53

| * | | tor-keymgr: Add script for generating test key files.Gabriela Moldovan2024-05-158-0/+2787
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `tor-keymgr/testdata` contains a bunch of OpenSSH keys used for testing. I meant to share the script I generated them with, but somehow never got around to it. Note: the OpenSSH keys generated by this script are going to look slightly different than the ones that are checked into the repo. This is because some of those original key files were generated ad-hoc (I manually modified them a while ago, but I forgot exactly how

| * | ChannelSender::poll_ready_unpin_bool: move to utilIan Jackson2024-05-293-20/+24
| | | | | | | | | | | | This is where it belongs.
| * | ChannelSender::poll_ready_unpin_bool: extension traitIan Jackson2024-05-292-1/+8
| | | | | | | | | | | | | | | | | | | | | This makes this available for any Sink + Unpin. Which we want because we're about to wrap our ChannelSender in a Sink wrapper. It's in the wrong place now; we'll move it in a moment.
| * | ChannelSender::poll_ready_unpin_bool: rename from poll_readyIan Jackson2024-05-292-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This would otherwise shadow the poll_ready method, which is confusing. Also this paves the way for making it available for any Sink + Unpin. Improve the docs somewhat to explain what this thing actually is.
| * | ChannelSender::poll_ready inherent method: Don't discard errorIan Jackson2024-05-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | I think this error was in fact always Error::CircuitClosed because it came from ChannelClosed.into(). Anyway, we shouldn't squash it. Now this function has semantics identical to Sink::poll_ready, just a slightly different signature.
| * | ChannelSender::poll_ready inherent method: Avoid apparent discardIan Jackson2024-05-291-1/+1
| | | | | | | | | | | | Make it clear we're discarding `()`, not an actual value.
| * | ChannelSender::poll_ready inherent method: Use Sink:poll_readyIan Jackson2024-05-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | We're going to change this function, but first we are going to make its behaviour identical to Sink::poll_ready. This avoids open-coding the call to poll_read on cell_tx. The error handling is still strange. We'll fix that in a moment.
* | | proto: Try to clarify why StreamReader has a StreamTarget.Nick Mathewson2024-05-292-3/+10

* | | proto: Add a test for closing streams.Nick Mathewson2024-05-291-1/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test verifies that when we invoke the code to close a stream, an END message is actually sent. The test comes in two versions: * `drop_stream` closes the stream by dropping it. It currently passes on main. * `close_stream` closes the stream by running `AsyncWriteExt::close` on the writer. It is a regression test for #1368. It currently fails on main.
* | | proto: Improve documentation about DataStream lifetimes and closingNick Mathewson2024-05-292-1/+40
| | | | | | | | | | | | | | | | | | | | | In particular, clarify that dropping the DataWriter on its own does nothing unless the DataReader is also dropped. Related to #1368.
* | | proto: Make DataWriter::close actually do something.Nick Mathewson2024-05-293-9/+41
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we had a bug where `<DataWriter as AsyncWrite>::close` (or `shutdown` in tokio-land) would not actually have any effect. It _would_ drop the `StreamTarget` held by the `DataWriter`, but since the `DataReader` also held a `StreamTarget`, the MPSC channel would not get closed, and the circuit reactor would not realize that the stream wanted to shut down. Now we use `mpsc::Sender::close_channel` to make our closes effectual. Closes #1368. Additionally, we fix a bug where `poll_close()` never actually did anything if the buffer had nothing in it when it was called. Previously, `poll_flush_impl()` would exit immediately if it had no data to flush. That isn't what we want when we are closing!

| * | proto: Divide up some elements of ChannelDetails.Nick Mathewson2024-05-162-52/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously ChannelDetails had a double duty: It held elements shared among the clones of a Channel, and it also held elements shared between the Channel and the Reactor. But now that Channel doesn't have to implement Clone, we can more the non-Reactor elements into Channel itself. This change may improve cache locality a bit, and should make it a little easier to follow the channel code. I've also moved unique_id out of ChannelDetails into Channel _and_ Reactor: it is small, immutable, and used all the time in logging.
| * | Make Channel non-Clone.Nick Mathewson2024-05-163-4/+6

| * | proto: Make Channel explicitly Arc<.>Nick Mathewson2024-05-1613-43/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, Channel was a type that you could Clone that implicitly its state. Now, Channel always appears as an Arc<Channel>. This change has several benefits: * It makes the relationship between Channel struct and the underlying channel more clear. * It enables Channel to participate in the RPC system, where everything has to be an Arc<.> * It enables us to have a Weak<Channel>, if we ever want to. * It will let us move various members out of ChannelDetails. We did this change a while ago with ClientCirc.
| * | proto: Move Channel send functionality into a separate type.Nick Mathewson2024-05-163-48/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This serves three purposes: * It removes the 'send a cell' method from the channel's public API. Nothing outside of tor-proto should have to use this. * It paves the way for giving each circuit a separate handle onto the channel's send functionality. This will eventually let the channel multiplex among circuits more intelligently. * It prepares for the next commit, which will make Channel itself universally Arc<.>ed.

| * | proto: Document usage for each mutable part of ChannelDetailsNick Mathewson2024-05-161-1/+12
| | | | | | | | | | | | | | | For all mutable shared state, we ought to know which part of the program sets it, which part of the program reads it, and why.
* | | chanmgr: Delegate to Channel::engage_padding_activities explicitly.Nick Mathewson2024-05-171-1/+1
|/ / | | | | | | | | | | (This isn't a bugfix, but it helps avoid the appearance of a function calling itself. This _would_ become a bug if we imported the wrong trait into scope here.)

| | | | | | | | | | | | | | | Now that Method::Error exists, we can downcast Any to the actual function's return type.
| * | RPC: Require an Error type in methods.Nick Mathewson2024-05-167-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | This is needed so that we can cast special methods' return types properly. I wish I could make this optional, but Rust doesn't allow defaulting an associated type.
| * | Rpc: Allow invoker_ents to be marked as @specialNick Mathewson2024-05-161-7/+21

| * | Relax Serialize requirement on method outputs.Nick Mathewson2024-05-162-11/+13
| | | | | | | | | | | | | | | Now Methods can return anything; and only if their outputs are Serialize will they implement RpcInvocable.
