| * | | | | proto: Only replace padding when the target will see it.Nick Mathewson2025-09-104-6/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we would replace padding with any cell that was already in the queue. But that doesn't make sense: If we have a cell queued for hop 1, then we shouldn't use it as padding for hop 2, since hop 2 will never see it! Instead, we look at the target hops for the already queued cells. Ref: - https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3225/diffs?commit_id=3998e0559fbcc06f8ea88968051cebca71489a52

| |/ / / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we replace padding with an _already queued_ cell, we should only trigger PaddingSent on the final hop's machine.

| * | | | proto: Simplify/correct padding-based blocking logic.Nick Mathewson2025-09-111-15/+32
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | The correction: We want to report a block as bypassable only if _every_ currently blocking hop has bypassable blocking. The simplification: We don't need to report the first hop that's blocking any more.
* / | | tor-proto: fix path of `semver.md`Steven Engler2025-09-111-0/+0
|/ / / | | | | | | | | | | | | `Release.md` gives a wildcard path of `crates/*/semver.md`, so it seems that these files should go in the top level of each crate.

| * proto: Use ConfluxCmd instead of CircuitCmd.Gabriela Moldovan2025-09-045-52/+58
| | | | | | | | | | | | This enables us to make the conflux handler logic implementation-agnostic (we want to avoid using `CircuitCmd` here, because it is specific to client circuits).
| * proto: Move abstract conflux handlers outside of the client module.Gabriela Moldovan2025-09-047-650/+657
| | | | | | | | | | | | | | | | | | | | This moves the shared types under `tor_proto::conflux`. Note: the shared types currently import `CircuitCmd` from `client`. A future commit will change the signature of `handle_msg` to return something other than `CircuitCmd` (this will also improve readability, because in reality, that function can never return most `CircuitCmd` variants).
| * proto: Move cmd_counts_towards_seqno to a new conflux module.Gabriela Moldovan2025-09-044-56/+64
| | | | | | | | | | | | | | `tor_proto::conflux` is where the shared conflux logic will live. Soon the generic parts of the conflux handlers will be moved there (whereas the client-specific `AbstractConfluxMsgHandler` impl will continue living under `tor_proto::client`).
| * proto: Make the ConfluxMsgHandler constructor take an abstract handler.Gabriela Moldovan2025-09-043-23/+17
| | | | | | | | | | | | This will enable us to pull `ConfluxMsgHandler` outside of the `client` module (this is needed because relays are meant to use this type as well, but with a different `AbstractMsgHandler`)

| * proto: Define a new composable SinkBlocker type.Nick Mathewson2025-09-045-0/+542
| | | | | | | | | | | | | | | | This type wraps a futures::Sink, and allows it to be temporarily blocked and unblocked. I'm going to use this to implement padding-based circuit blocking, according to the designs in !3225.
