SNOCAT

Streaming Network Overlay Connection Arbitration Tunnel

Crates.io docs.rs License: MIT License: Apache 2.0

snocat is a framework for forwarding streams across authenticated, encrypted QUIC tunnels, from a tunnel aggregator to a dynamic set of clients.

When used as a library, libsnocat allows a dynamic set of clients to connect over UDP to a server, and forwards TCP streams from the server to the clients.

snocat-cli is a command-line tool for TCP reverse tunnelling over the QUIC protocol. It allows small-scale port redirection akin to SSH Remote Forwarding.

Third-Party Dependencies

Primary crates used include the Tokio stack and futures-rs for async-await capabilities, Quinn for its QUIC implementation.

Various other dependencies are included under their respective licenses, and may be found in snocat/Cargo.toml and snocat-cli/Cargo.toml.

  • avoid incoming breakage of `for<'a> &'a T: 'a` bounds

    avoid incoming breakage of `for<'a> &'a T: 'a` bounds

    https://github.com/rust-lang/rust/pull/98109 fixes a soundness hole in rust. Unfortunately, this fix exposes an other known bug in reasoning about bounds of the form for<'a> &'a T: 'a. This bug can be illustrated in the following example which is rejected since v1.0!

    fn require_bound<T>()
where
    for<'a> &'a T: 'a,
    // T: 'static // <- rustc incorrectly thinks it must prove this bound for the above bound to hold.
{
}

fn test<T>() {
    require_bound::<T>();
    //^ ERROR  type parameter T doesn't live long enough
}

    One way to work around such bug is to simply remove the bound since it is always satisfied for any type T.

    We tried to fix this in a timely manner, but it's not a particularly easy problem. Indeed it is part of a long-term initiative under the name of "implied bounds" to better support these bounds. Sorry for any inconvenience!

    Changelog

    Sourced from regex's changelog.

    1.5.5 (2022-03-08)

    This releases fixes a security bug in the regex compiler. This bug permits a vector for a denial-of-service attack in cases where the regex being compiled is untrusted. There are no known problems where the regex is itself trusted, including in cases of untrusted haystacks.
