| * proto: Remove TODOs about panics on double-close.Nick Mathewson2023-10-192-31/+2
| | | | | | | | | | | | | | Now that `StreamMap::terminate` no longer panics, and now that it permits the kind of double-call that we allow, we can close #1065. Closes #1065.
| * proto: Have EndSent remember if we have dropped the stream target.Nick Mathewson2023-10-192-14/+46
| | | | | | | | | | The rule is that we allow up to one explicit `close_pending`, followed by exactly one final `mpsc::Sender` drop.
| * proto: Give StreamMap::terminate a "why" argumentNick Mathewson2023-10-192-7/+45
| | | | | | | | | | We will use this to enforce correct ordering on "close" vs "drop" APIs.

* | proto: Make StreamTarget::close() misuse less likely.Nick Mathewson2023-10-172-5/+9
|/ | | | | | | | | It turns out that we can make `IncomingStream::reject()` consume self, thus making it impossible to hit the double-close error from outside the `tor-proto` crate. Also, we rename `StreamTarget::close()` to `close_pending()` to better reflect its limited applicability.

| * proto::stream::incoming: Use bit-array representation for command listNick Mathewson2023-10-122-7/+85
| | | | | | | | | | This should be smaller and faster than vec, and save some allocations. It could also avoid a tiny sidechannel.
| * tor-proto: remove a now-unneeded allow in stream::incomingNick Mathewson2023-10-121-2/+0

| * Remove the (fairly bogus) HsNtorServiceInput type.Nick Mathewson2023-10-122-80/+38
| | | | | | | | This will let avoid some copying inside our HSS code.
| * proto: Remove a TODO about merging two functions.Nick Mathewson2023-10-121-2/+0
| | | | | | | | | | There is some similarity, but there's not really a logical way to combine the two that actually results in less, clearer code.

| * tor-proto: Refactor the key derivationEmil Engler2023-09-292-15/+42
| | | | | | | | | | | | | | | | | | | | | | | | This commit refactors the key derivation, by applying the following: - The spaghetti slice creation with the hard-to-read boundaries got replaced by a closure, which accepts a length, advances the seed slice by n bytes as a side-effect, and returns the just advanced bytes - The use of `.except` got replaced by an `.or`, with the use of the already existing `InvalidKDFOutputLength` error, thereby removing a potential panic (probably not reachable in runtime though) - The conversion from a slice to a `CircuitBinding` got moved into a `TryFrom` trait of the appropriate data structure

| * Remove direct dependency on generic-arrayNick Mathewson2023-09-284-7/+4
| | | | | | | | | | | | | | | | | | | | Instead of tying ourselves to a particular version of the generic-array crate, we now always use the version re-exported by our RustCrypto crates. This lets us avoid the possibility of version mismatch. (Originally I had planned to upgrade to generic-array 1.0, but then I found that we were not actually using it.)
* | tor-proto: Replace repeating pattern with fillEmil Engler2023-09-281-6/+2
|/ | | | | | | | | This commit replaces a repeating code pattern in the `set_digest` function for setting the 'Recognized' and Digest field to zero with a slice fillment. Besides this, it also adds comments explaining which fields are currently getting zeroized.
* tor-proto: Make allow_stream_requests() not return a ResultNick Mathewson2023-09-271-4/+4
| | | | | | | The function never yields anything but an `Ok`, so we can simplify its type. (Not a stable feature, so no semver entry needed)

| * Generate padding in Introduce1 messages.Nick Mathewson2023-09-181-7/+41
| | | | | | | | | | | | Closes #1031. This padding ensures that the introduction point doesn't learn the length of the plaintext being sent to the onion service.

* | hs_ntor: allow attempting handshake with a set of subcredentials.Nick Mathewson2023-09-201-27/+45
| | | | | | | | | | | | | | Since we are using the same introduction point circuits for multiple time periods, we need the ability to provide a set of subcredentials and see which of them acually works. Fortunately, we "only" have to do digest operations here, which are much faster than public key.

* | tor-proto: Remove the Display impl of HopNum.Gabriela Moldovan2023-08-252-15/+9
| | | | | | | | | | This removes the `Display` impl of `HopNum` and replaces its usage with `HopNum::display`.
* | tor-proto: Add a HopNum::display function.Gabriela Moldovan2023-08-253-5/+41
| | | | | | | | | | | | | | | | | | This function can be used to display a more user-friendly representation of a `HopNum`. This will print hop numbers as 1-indexed values: #1, #2, etc.. We will soon remove HopNum's Display implementation in favour of `.display()`.
* | tor-proto: Make HopNum indices appear 1-based in the Display impl.Gabriela Moldovan2023-08-251-1/+4
|/ | | | | | | | | | This makes `HopNum`s display as 1-indexed values. This will make error messages more intuitive, because when talking about an N-hop circuit, we generally speak in terms of hops 1..N (rather than 0..N-1). Internally, our `HopNum` indices are still 0-based. Closes #996
