hsservice: Stop using HopNum and use TargetHop

2025-06-26T14:18:30Z

This requires some changes to the tor-proto crate to handle the inbound TargetHop from the HS subsystem and then resolve it into a HopNum for a single circuit. It is expected that this will change again with Conflux to only use HopLocation internally in a Tunnel and then use HopNum into a Circuit. Signed-off-by: David Goulet

proto: Make send_raw_msg() use a TargetHop

2025-06-26T14:18:30Z

In order for this to work, a last_target_hop() function is added to ClientCirc in order to return a precise hop location as a TargetHop of the last hop. This is needed because in the HS subsystem, we need such value in order to get a location on the last physical hop before adding the virtual hop. The RDV1 cell is sent to that last target hop while the allow_stream_request() is done on the virtual target hop. Signed-off-by: David Goulet

proto: Move NegotiatedHopSettings to a higher level

2025-06-10T15:52:28Z

We will construct this object based on the circuit parameters _and_ on the target's supported protocol versions, so we need to do so when we have both pieces of info.

Add methods for getting proof-of-work extension from intro request.

squash! Upgrade rand dependency to 0.9.

2025-03-18T16:09:44Z

- `rand::thread_rng()` has been deprecated and renamed to `rand::rng()`

circmgr: Remove the CircParameters build .expect()

2025-01-16T14:16:01Z

Instead, return an error and make all call site handle it. Signed-off-by: David Goulet

circ: Specialize the circparams from netparams function

2025-01-16T14:16:01Z

Congestion control parameters have specific values depending on the circuit type. Instead of using a CircuitType, which is removed in this commit, specialize the function in this case onion and exit. This allows us to get rid of CircuitType and solely use TargetCircUsage instead. At this commit, we use .expect() on the Builder. Future commit will remove this to return a Result in case of failure. Worth noting that we don't expect one. Signed-off-by: David Goulet

circmgr: Modify CircParameters for congestion control

2025-01-16T14:16:01Z

The congestion control parameters are created from the consensus parameters (netparams) and then put into the CircParameters object that is then passed down the tor-proto crate. Because different parameters are selected depending on the circuit type (onion vs exit vs sbws), a CircuitType enum is introduced for the sole purpose of being used to select the right parameters.

hss: Make the limit for streams configurable.

2024-03-26T16:55:05Z

Closes #1124.

Add an IncomingStreamRequestFilter to check early properties

2024-03-26T16:55:05Z

Based on designs in #1124. Note that there is a TODO here about a hack I had to do to appease the borrow checker.
