| * | tor-proto: take `CreateRequest` message by referenceSteven Engler2026-04-082-6/+5
| | | | | | | | | | | | | | | Clippy has started warning about this since we moved the CREATE_FAST handling to a helper, so this resolves that.

| | | | | | | | | | | | Fix formatting from previous code movement.
| * | tor-proto: move CREATE_FAST handlingSteven Engler2026-04-081-45/+43
| | | | | | | | | | | | | | | This moves the code, changes the indentation, and wraps the result in an `Ok()`.

| * | tor-proto: remove old TODOSteven Engler2026-04-081-1/+0
| | | | | | | | | | | | This had already been resolved.
* | | proto: Bring back AuthLogDigest and explicitly convert to SLOG/CLOGDavid Goulet2026-04-084-36/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From opara's comment: https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3844#note_3388789 Keep the low level AuthLogDigest type alias and return it. The callsite is the one deciding if the returned digest is a Clog or a Slog. Related to #2441 Signed-off-by: David Goulet <[email protected]>
* | | proto: Add ClogDigest and SlogDigest typesDavid Goulet2026-04-087-38/+80
|/ / | | | | | | | | | | | | | | | | Introduce those types in order to avoid mixing them up as the previous AuthLogDigest was just a type alias over [u8; 32] Fixes #2441 Signed-off-by: David Goulet <[email protected]>

| * | Revert "tor-proto: change `CreateResponse` to `restricted_msg!`"Steven Engler2026-04-082-29/+20
| | | | | | | | | | | | This reverts commit 9c38daf2d3548feca2ff555f5bd52165add0d20c.
| * | tor-proto: add a `From<$ttype>` impl for `RestrictedChanMsgSet`Steven Engler2026-04-081-0/+8
| | | | | | | | | | | | This is needed for the revert in the following commit.
| * | tor-{proto,chanmgr}: change how channels accept a CREATE* handlerSteven Engler2026-04-088-85/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of giving the `CreateRequestHandler` to the channel after it's constructed, we integrate it into the handshake so that we can give it to the channel constructor. The `ChannelType` is no longer part of the `Channel`. Some of the tests could be cleaned up slightly now that the channel doesn't need the `ChannelType`, but I don't want to conflict with !3853.
| * | tor-proto: simplify error handling in `CreateRequestHandler::handle_create()`Steven Engler2026-04-081-71/+85

| * | tor-proto: rename `CircIdRange::is_allowed_by_peer()` to `is_allowed_for_peer()`Steven Engler2026-04-081-2/+2

| * | tor-proto: add `Channel::set_create_request_handler()`Steven Engler2026-04-082-2/+62
| | | | | | | | | | | | | | | | | | We can't pass the request handler during the `Channel` constructor since it would require conditionally compiled function arguments, which aren't nice.
| * | tor-proto: add `CreateRequestHandler`Steven Engler2026-04-084-0/+442
| | | | | | | | | | | | for handling CREATE* messages on channels.
| * | tor-proto: extend `RelayHandshakeError`Steven Engler2026-04-081-1/+27
| | |
| * | tor-proto: add a `CreateRequest` restricted msg setSteven Engler2026-04-081-1/+11
| | |
| * | tor-proto: change `CreateResponse` to `restricted_msg!`Steven Engler2026-04-082-19/+29
| | | | | | | | | | | | | | | This better fits with existing code that uses `restricted_msg!` and is a bit more flexible.
| * | tor-proto: derive `strum::EnumDiscriminants` for `Algorithm`Steven Engler2026-04-081-1/+4
| | |
| * | tor-proto: small cleanup of legacy codeSteven Engler2026-04-081-6/+1
| | | | | | | | | | | | | | | | | | | | | I think it was written like this because earlier versions of rust didn't allow references to temporaries like `&mut rand::rng()` and needed them to be bound to a variable. But this isn't necessary anymore and so the comment doesn't make sense.
| * | tor-proto: change channel to use `Runtime`Steven Engler2026-04-086-26/+44
| | | | | | | | | | | | | | | When used for relay channels, the channel reactor will soon need to spawn relay circuit reactors.
| * | tor-proto: support relay circs in channel's `CircMap`Steven Engler2026-04-082-11/+87

| * | | tor-proto: change an error to `NotConnected`Steven Engler2026-03-291-3/+7
| |/ / | | | | | | | | | | | | Returning `CircuitClosed` isn't right here since the circuit may not have closed.
* | | tor-proto: lower log level of "removing circuit leg"Steven Engler2026-04-061-1/+1
| | | | | | | | | | | | This appears often in the arti logs, but is a normal thing to happen.

| * | | tor-proto: allow sending DATA cells on closed streamsSteven Engler2026-03-291-6/+12
| |/ / | | | | | | | | | | | | Previously we would close the circuit, which isn't great because there can be other streams in use on the circuit.
* | / proto: Take current time as an argument when constructing padder.Nick Mathewson2026-03-312-7/+12
| |/ |/| | | | | | | | | | | Previously we'd get the time by calling Instant::now, but that would lead to a mismatch with the runtime if we were mocking. Part of #2428.

* | cell: Add Authenticate::BODY_LEN as a public constDavid Goulet2026-03-301-2/+1
| | | | | | | | | | | | | | We use this constant value when building the AUTHENTICATE cell to optimize the memory allocation as this won't ever change. Signed-off-by: David Goulet <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | This object contains a melting pot of public keys, private keys and certificates. Rename it to reflect that it is channel authentication material and not "identities. https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3791#note_3374454 Signed-off-by: David Goulet <[email protected]>
* | proto: Remove noop function for initiator channelDavid Goulet2026-03-301-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | No need to call `set_authenticated()` for a relay initiator channel because relay initiator channel are always authenticated and thus the underlying channel cell codec will always use the R2R restricted message set. This is only useful to a relay responder channel. The naming of that function is not great actually and should probably change. Signed-off-by: David Goulet <[email protected]>
* | proto: Rename many variables with more fine grained namingDavid Goulet2026-03-306-120/+137
| | | | | | | | | | | | | | | | | | | | Mostly, identity a `ChanTarget` as a "target" since we juggle with PeerInfo and OwnedChanTarget nowadays. All certificate and keys have very specific names which attempts to match the spec as much as possible. Signed-off-by: David Goulet <[email protected]>
* | proto: Transform inner into verified after verificationDavid Goulet2026-03-302-20/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Only get the inner generic unverified channel into a verified channel after the actual verification in the relay responder handshake. Some variables needed a rename as this was dangerously named.
