            Bug ID: 50520
           Summary: Any Rust-Lang application: Cannot create an async tcp
                    connection
           Product: Wine
           Version: 5.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: winsock
          Assignee: wine-bugs at winehq.org

minimal example

Rust applications are not able to use async libraries in wine. TCP connections
send Syn, receive Syn/Ack, send Reset.

Test matrix:
 - Wine versions 5.0, 5.8, 5.22, 6.0rc0 , 6.0rc6
 - Ubuntu, Arch
 - WSL, native on laptop
 - Tokio, Smol, Async-Std (Smol and async-std use the same under the hood)
 - Rust versions 1.48 stable, 1.49 stable, 1.50 beta
 - Targets windows-gnu, windows-msvc
 - Toolchains gnu, msvc

Every combination fails to connect.

Minimal example source code: https://pastebin.com/SZavTYD7
precompiled binary 1.50 beta/windows-msvc/msvc attached.
The example expects a listener on localhost:41206!
You can easily open one with ncat -l -k -p 41206

The error returned to rust:
[src\main.rs:10] TcpStream::connect(addr.as_slice()).await = Err(
    Os {
        code: 10045,
        kind: Other,
        message: "OS Error 10045 (FormatMessageW() returned error 317)",
    },
)
