* | | tor-proto: Introduce CircHopList, hide CircHop internals.Gabriela Moldovan2025-06-103-244/+399
| | | | | | | | | | | | Most of this is code motion, I recommend reviewing with `--color-moved`.
* | | tor-proto: Move CircHop to a separate module.Gabriela Moldovan2025-06-102-163/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This helps hide the `CircHop` internals, and is the first step towards providing a safer API that aims to reduce contention and prevent deadlocking on the stream map mutex. This change is also in preparation for implementing special handling for the join point of a conflux tunnel (which will involve adding a new `CircHop` API for sharing the stream map of another `CircHop`). I recommend reviewing this diff with `--color-moved`.

| * | | Avoid a bug with HopSettingsNick Mathewson2025-06-102-5/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When negotiation won't occur, we need to represent the fact by disabling any settings that would depend on negotiation. Otherwise we'll wind up with the client thinking everything was supported, and the relay thinking that nothing is.

| * | | proto: Refactor cc fallback.Nick Mathewson2025-06-104-19/+27
| | | | | | | | | | | | | | | | | | | | The fallback CC algorithm is _always_ fixed-window, and we should only use it when the selected CC algorithm is not supported.
| * | | Move responsibility for choosing extensions into tor-protoNick Mathewson2025-06-103-25/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now tor-circmgr no longer needs to check which Protover capabilities are enabled, or construct a separate CircParameters for each hop. Instead, tor-proto decides whether to use the fallback CC mode, based on whether the target supports FLOWCTRL_CC. Closes #1967.
| * | | proto: Move NegotiatedHopSettings to a higher levelNick Mathewson2025-06-108-61/+97
| | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | | proto: Split CircParameters and NegotiatedHopSettingsNick Mathewson2025-06-106-32/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One type will now represent _the kind of hop we are asking tor-proto to negotiate_; the other will represent _the state of such negotiation_. This doesn't simplify the code much yet, but it will be helpful as we add more and more negotiable settings. Part of #1967

| * | tor-rtcompat: Remove rustls dependency in favor of futures-rustlsparazyd2025-06-062-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | futures-rustls provides and re-exports rustls and thus the rustls dependency is redundant. Additionally, this removes `aws-lc-rs` and its inherent dependencies from `Cargo.lock` and the entire project since they've been included because the rustls dependency did not use `default-features = false` and rustls by default now depends on `aws-lc-rs` as its crypto engine.

| * | NetDir::pick_n_relays: avoid some unwarranted warningsJim Newsome2025-06-051-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we logged a warning whenever `choose_multiple_weighted` returns `Ok(iter)`, whenever `iter` contains fewer relays than requested. However, this is expected behavior of `choose_multiple_weighted` if the filtered list of relays doesn't have the requested number of relays, in which case it should return all of the relays in the filtered list. In particular, this condition occurs regularly in test networks when looking for candidate relays to add to the potential guard set while excluding those already in the potential guard set. We still warn if the returned list is fewer than requested, *and* fewer than available in the filtered list.
