* Make filter conditional, to fix build with hs-service disabled.Nick Mathewson2024-03-262-2/+6
|
* Refactor and simplify ClientCircSyncViewNick Mathewson2024-03-262-34/+24
| | | | | | | | With this patch, it holds only a reference to `&reactor.hops`, which greatly simplifies the reactor code's fight with the borrow checker. I've left some TODO comments about future directions here.
* Rename the old IncomingStreamRequestContext to StreamReqInfo.Nick Mathewson2024-03-263-9/+7
| | | | (Doing this to prevent us having two structs with the same name.)
* Add an IncomingStreamRequestFilter to check early propertiesNick Mathewson2024-03-265-12/+136
| | | | | | | Based on designs in #1124. Note that there is a TODO here about a hack I had to do to appease the borrow checker.
* Define a type for a synchronous (blocking) view of a circuit state.Nick Mathewson2024-03-263-0/+40
| | | | | We'll use this as an argument for the callback that checks stream requests to make sure they're permitted.
* proto: Make StreamMap keep a count of open streams.Nick Mathewson2024-03-261-0/+34
|
* proto: Prevent general state-transitions on StreamEntNick Mathewson2024-03-262-38/+60
| | | | | | We want to keep an accurate count of the number of open streams, so we have to stop exposing `&mut StreamEnt` outside of the streammap module.
* proto: Refactor circuit::streammap::StreamEntNick Mathewson2024-03-262-40/+51
| | | | | | | This is the first part of a refactoring that will let us keep code from the outside of `streammap` from changing a stream from one state to another. And we need to do _that_ so that StreamMap can count how many open streams it has.

|
* Refactor the logic for constructing crypt layers.Nick Mathewson2024-03-263-77/+95
| | | | | | | | | | | The key insights here are: - That relay cell format and crypto protocols aren't orthogonal: Once we have GCO, it will require V1. - That we only need the actual functions for layer construction to be generic; we don't need to proliferate generic parameters everywhere. - That the circuit::handshake module already does most of what we want.
* Add and use RelayCellFormatTraitJim Newsome2024-03-204-113/+129
| | | | | | This lets us paramaterize types and functions by a particular relay cell format. We use this e.g. to statically parameterize the cell crypto functions, thereby removing some run-time branching in the hot path.

* relay-cell: Update relay cell decoding API for prop340Jim Newsome2024-03-125-28/+104
| | | | | | | | | | | Prop 340: https://spec.torproject.org/proposals/340-packed-and-fragmented.html This updates the decoding API to support multiple versions of the relay cell encoding, including the new encoding proposed in prop340 that supports relay message packing and fragmentation. This commit doesn't actually add support for that new encoding yet.
* Rename UnparsedRelayCell -> UnparsedRelayMsgJim Newsome2024-03-1210-39/+39

* | tor-cert: Bump minor version.Gabriela Moldovan2024-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | We bumped the minor version of `tor_checkable`, which is used in the `tor-cell` public APIs (e.g. `Ed25519Cert` implements `tor_checkable::Timebound`, using `tor_checkable::TimeValidityError` as its error type). This bumps the minor version of `tor-cert` (including for its dependents).

* tor-proto: Add function for peeking at pending circ unique ID.Gabriela Moldovan2024-02-271-0/+5
| | | | | | | | | `tor_circmgr::Error::Protocol` will soon include an optional `UniqId`. Since `Protocol` errors can be caused by pending circuits, we need to be able to peek at their `UniqId`. Part of #1297
* tor-circmgr: Add a helper for displaying optional UniqIds.Gabriela Moldovan2024-02-272-1/+18
| | | | | | | | Some of the `tor_circmgr::Error` variants will include the `UniqId` of the corresponding circuit, so we'll need to be able to display it without the `Circ ` prefix. Part of #1297

| * proto: Close circuit _intentionally_ when Request Sink is dropped.Nick Mathewson2024-01-172-8/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In theory, it might be better to just un-register the IncomingStreamRequestHandler when the Receiver for the stream requests is dropped. However, there are two reasons not to do so: 1. It's tricky. We never actually poll on the corresponding Sink, so there isn't a place where the Reactor would expect to get a prompt notification of closure. We only find out that the Receiver has been dropped when an attempt to send on the Sink returns an `is_disconnected` error. 2. It's unnecessary. In the Tor protocols, once we have decided to accept incoming stream requests on a circuit, we want to continue to do so until one of the parties closes the circuit. I've documented this in several comments, in case whe want to get fancier in the future. Closes #1188.

* Downgrade and convert TODO HSSs to #1190.Nick Mathewson2024-01-101-2/+2
| | | | | | | | | These are about making allow_incoming_streams give an error if a handler is already installed. I'm calling these non-MUST, since they don't affect the actual API here, and we already have comments telling you not to do that. We can add them later.
