| * | proto: Use congestion control in circuit reactorDavid Goulet2025-01-166-49/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is official, congestion control is now used at this commit by the circuit reactor making circuit/sendme.rs unused. Will be removed with another commit. Related #534 Signed-off-by: David Goulet <[email protected]>
| * | circmgr: Modify CircParameters for congestion controlDavid Goulet2025-01-1611-89/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The congestion control parameters are created from the consensus parameters (netparams) and then put into the CircParameters object that is then passed down the tor-proto crate. Because different parameters are selected depending on the circuit type (onion vs exit vs sbws), a CircuitType enum is introduced for the sole purpose of being used to select the right parameters.

| * | proto: Add Vegas congestion control algorithmDavid Goulet2025-01-163-0/+599
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The big one! This is the Vegas algorithm implementation that is hooked to the CongestionControl object by implementing the algorithm trait. Still, at this commit, nothing is being used by the circuit reactor yet.

| * | proto: New CongestionControl object and fixed window algorithmDavid Goulet2025-01-164-7/+745
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the top level CongestionControl object that will allow the circuit reactor to use it in order to decide if a cell can be sent or not. In order to be used, it is configured with an algorithm that implements the CongestionControlAlgorithm trait. The Fixed Window algorithm is also added which essentially implements the SENDME logic as arti knows it today with a fixed window size. The SENDME code has been refactor in two different logical steps in order to accomodate the future Vegas algorithm for which the congestion window logic and SENDME validity is seperated. There is now a SENDME validator that takes care of tracking the tags (authenticated SENDMEs) and validating them upon reception. Then, if valid, the window management is passed down the congestion control algorithm, at this commit, FixedWindow object. Related #534 Signed-off-by: David Goulet <[email protected]>
| * | proto: Add generic objects for congestion controlDavid Goulet2025-01-164-0/+658
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds the congestion window object, a round trip estimator (RTT) and a state enum. These 3 entities are used by congestion control in a generic way that is they are passed and used by any algorithm. At this commit, they are not used hence the allow deadcode attribute for now in order to minimize the build warnings. We also introduce the params.rs file containing the parameters, taken from consensus, used to configure these objects. They will be exposed to the tor-cirmgr crate to build the CircParameters. More will come. This also introduces the congestion/ directory that will contain more code in future commits. Related #534 Signed-off-by: David Goulet <[email protected]>

| | | | | | | | | | | | | | | | | | We don't want to call this "unix path" anywhere, since it corresponds to _any_ case where the ability to negotiate a successful connection means that the client is authorized. We also don't want to call it "none": The authentication is inherent to the connection, not nonexistent.
| * rpc: Tweak cookie protocol to bind both nonces.Nick Mathewson2025-01-153-8/+20
| | | | | | | | | | | | | | | | | | | | Previously participants in the cookie protocol only bound the peer nonce in their MACs. With this change, they bind both nonces. This change is _probably_ not necessary for security, but it can't hurt. It follows a general principle that Adam Langley told me a long time ago: you won't regret binding more, but you might regret binding less.

| | | | | | | | | | | | | | | | | | | | | We think that for relays, the 'override_net_params' config option is overly broad and a footgun. We can always re-add this back later if we want to, but for now the focus will be on exposing specific config options for features that are okay to be changed by users.
