proto: Remove the AUTHORIZE as a parsable cell

2025-08-21T15:59:37Z

The AUTHORIZE cell command is simply reserved but not defined. The tor specification, at this point in time, is allowing such cell before the handshake starts but it is very unclear on what ordering is allowed nor how many can are allowed. C-tor silents drop them like VPADDING and so clearly unused. Instead of dealing with it, simply remove its support but keeping its reserved number. Signed-off-by: David Goulet

tor-hsservice: Change capping of PoW effort.

2025-08-13T18:43:05Z

This caps the PoW effort during sorting, rather than at intake. This allows us to record efforts that are capped in our metrics histogram while only recording metrics after the PoW solve has actually been verified.

Remove semver.md files, post-release.

tor-cell: change `UnparsedRelayMsg::data_len`

2025-07-15T06:04:44Z

It now performs some validation and can return a `Result`. We perform validation here since different cell formats may have different maximum data lengths in the future, and `UnparsedRelayMsg` doesn't expose the cell format so it's difficult to perform this validation at a higher layer.

tor-cell: remove `flowctl-cc` feature and make XON/XOFF cells stable

2025-07-15T05:33:18Z

I don't see any further changes being needed for these types, and it simplifies a lot of future code in tor-proto that uses these types.

release: Delete semver.md files after release.

cell,proto: Split request/response extensions into seprate types

2025-05-07T12:44:59Z

Implements part of proposal 358.

Rename NtorV3Extension to CircRequestExt

2025-05-07T12:41:39Z

This type will, because of prop358, be shared by ntorv3, hs-ntor, and probably other future handshakes. There will also be a CircResponseExt type.

proto, cell: Remove RelayCellFormatTrait.

2025-05-06T22:34:17Z

The purpose of the trait was to parameterize the tor1 cell crypto on the different possible relay cell layouts. It made sense to have this trait when we thought we would implement the new cell layout for prop340 (packed-and-fragmented) well before we implemented CGO. But it now appears all but certain that CGO will land long before we make any more headway on prop340. Therefore, it doesn't make sense to carry the ability to customize `tor1` for other relay cell layouts. Removing this trait saves a fair bit of complexity.

proto: Use SendmeTag in place of CircTag

2025-05-06T22:34:17Z

This doesn't make much change yet, but does save us an allocation when handling SENDMEs.
