proto: Make crypt layers take a ChanCmd argument

2025-04-29T16:31:09Z

CGO will need this argument so that it can authenticate the command as part of its crypto operations. (Trying to meddle with RELAY vs RELAY_EARLY will no longer work!)

tor-proto: only use congestion control if "flowctl-cc" feature is enabled

2025-04-23T18:39:16Z

Congestion control is not completely working correctly, and is not fully implemented (XON/XOFF). This commit adds a new experimental "flowctl-cc" feature to enable the congestion control extension during the ntor-v3 handshake.

tests: Add CC ntorv3 negotiation unit test

2025-04-23T18:36:28Z

Also add one for the sendme_inc validity function. Part of #1817 Signed-off-by: David Goulet

circ: Remove CircParameters reference in call stack

2025-04-23T18:36:28Z

This avoids cloning the object and instead allows us to have a CircParameters per hop on the circuit path. This will come handy with congestion control where each hop might have different congestion control parameters. Part of #1817 Signed-off-by: David Goulet

proto: Create StreamTargets with the right RelayCellFormat.

cell, proto: Use correct Data sizes for v1 relay cells

2025-04-16T14:58:49Z

Since v1 cells have a longer tag, they can fit less data into a single cell. Ah well, that's the cost of improved security. The code in data.rs is a little wonky, in that it currently requires its buffer to be exactly the maximum size for a data cell. We have a TODO about fixing that in the future, but for now I've moved it to use a boxed slice rather than a boxed array. Part of #1944.

Add a RelayCellFormat argument to encode().

2025-04-16T14:58:49Z

This will let us actually _send_ messages in the right format. This approach is not ideal for packed/fragmented messages; they will need a separate RelayCellEncoder. part of #1944.

tor-proto: removed "ntor_v3" feature flag

2025-04-01T14:16:33Z

ntor v3 is now always enabled.

tor-proto: begin using `TargetHop` and `HopLocation`

2025-03-11T14:53:15Z

This doesn't yet change the public API, it just begins the work of plumbing these around throughout `ClientCirc`, `Reactor`, etc. This can't be broken up into smaller commits without causing build failures.

tor-proto: add a non-pub `ClientCirc::legs()` method
