| * | | circ: Request congestion control with ntorv3 extensionDavid Goulet2025-04-232-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This puts in, based on the circuit parameters, the CC extension request in the CREATE and EXTEND requests. Part of #1817 Signed-off-by: David Goulet <[email protected]>
| * | | circ: Apply possible subprotocol changes to circ paramsDavid Goulet2025-04-232-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Congestion control can change the circuit parameters if the relay we are negotiating with doesn't support FlowCtrl=2. This commit adds a function in the circuit builder that will apply any changes to the circuit parameters of the hop based on the hop protocol values. For now, only congestion control applies.

| * | | circ: Remove CircParameters reference in call stackDavid Goulet2025-04-237-31/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <[email protected]>
| * | | congestion: Setup a fallback algorithm in the paramsDavid Goulet2025-04-233-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CircParameters is built before path selection and thus once we start building the hops, we can't access the consensus values that were used to build it in the first place. For congestion control, we require a fallback algorithm in case the hop doesn't support FlowCtrl=2. This commit adds a "fallback_alg" to the CC parameters which will be used for this exact case.

| * | | circ: Set the negotiated CC sendme_inc from handshakeDavid Goulet2025-04-232-7/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving the congestion control response extension, evaluate our state and set the sendme_inc if valid in our circuit parameters. For this, a series of helper functions is needed. Part of #1817 Signed-off-by: David Goulet <[email protected]>
| * | | circ: Make CircParameters mutable in the call stackDavid Goulet2025-04-233-12/+15
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is required because circuit ntor v3 handshake can negotiate circuit level parameters and thus able to change any values. Needed for congestion control ntorv3 handshake extension for which the sendme increment is negotiated. Part of #1817 Signed-off-by: David Goulet <[email protected]>

| * | | tor-consdiff: Replaced an old MSRV TODO with a link to why it shouldn't be donehashcatHitman2025-04-231-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - After spending quite a while trying to figure out why the tests kept failing after making the change, I eventually stumbled upon the netdoc syntax specification, which helpfully informs me that newlines MUST be ignored and discarded. Switching to using [`str::split_inclusive`] would either require extra lines to workaround and recreate the current expected behavior or changing the spec and correcting the tests to align with the new expected behavior.
| * | | tor-consdiff: standardized MSRV TODOhashcatHitman2025-04-161-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Part of a series of commits aimed at replacing all MSRV-related TODOs with a standardized format, which should be easier to find when the MSRV is bumped. For this one in particular, we actually do already meet the MSRV specified, but I want to check on the implementation details to see if this is still desired, since the TODO is 4 years old.

| * | | integration-e2e-shadow: move simulation seed to yamlJim Newsome2025-04-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | Since this significantly affects the behavior of the simulation, it's probably worth having it in the yaml. (It can of course still be overridden from the command-line).

| | | | | | | | | | | | | | | | | | | | | | | | Since this significantly affects the behavior of the simulation, it's useful to have it in the yaml for reference or if the simulation is manually rerun from the yaml.

|/ / / | | | | | | | | | | | | | | | | | | | | | This should make the simulation results generally more stable with respect to small perturbations, such as adding logging. It also causes a previous "heisenbug" failure in this test to reliably reproduce in every run.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the directory code, we have functionality to advance the consensus download state whenever possible, even if there is more we could download in the current state. That's fine, but when we're in this position, we need to be sure that we're taking any action based on the current state (such as installing notably parameters or, notably, protocol recommendations) before we move on.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This doesn't need to be perfect, but we need to use it to see if a consensus is new enough that we should obey its recommendations. This commit also adds a script to update or check our release date, and calls this script from our cargo-publish script.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to store this separately from the consensus, because we want to access it very early in our load-from-cache process, without checking the consensus that contains it for timeliness.

| | | | | | | | | | | | | | | | | | | | We'll want this so that we can expose them before we expose the rest of the consensus (which we need to do for spec conformance).

| | | | | | | | | | | | | | | | Also, add a new ErrorKind for this sort of error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of #1849. Note that these functions are distributed across crates, so that if (in the future) we stop doing API breaks with every release, we will get the right outputs. Note also that these functions build the list of protocols out of specific symbolic features, rather than numbers: this makes it easier to avoid errors about "which feature was Relay=4 again", and easier to avoid accidentally referring to a protocol that doesn't exist, like "Consensus" (should be "Cons") or "HsDir" (case is wrong).
