mitmproxy-wireguard

• Fix check that prevents initializing multiple TCP connections when receiving duplicate SYN packets.
• Update dependencies (including tokio 1.22.0). Raises MSRV to 1.64.0.

• Expose the "original" (i.e. not the address inside the WireGuard tunnel) source address of WireGuard UDP packets in TcpStream via TcpStream.get_extra_info("original_src").
• Internal refactoring to simplify code for spawning TCP connection handler coroutines, which makes it possible to check whether they raised an exception (which were previously just silently ignored).
• Update all Rust dependencies, including an update to PyO3 v0.17.3, which is the first release that marked support for Python 3.11 as official.

• Ensure that the virtual network device does not block unnecessarily and that it is always polled when necessary. Fixes a regression that was introduced in version 0.1.16.

• Optimize event processing in the internal network stack by always consuming as many events as possible before polling the virtual network device and processing open TCP sockets.
• Ensure that only one TCP socket is created per connection, even if SYN packets are resent for some reason.
• Channel sizes for processing events in the internal network stack are increased to avoid errors with full channels when some tasks don't keep up.
• Logging calls are removed from the network task's hot loop unless the project is built in debug mode.
• Failures to send to channels that were already closed when processing data that was received for sockets are now ignored to avoid crashes.

With this version, source files for the test client binary are manually included in published sdists to ensure the sources which are published on PyPI can actually be built. d'oh ...

• Increase buffer size for WireGuard packets to accommodate large outgoing packets.
• Check length of outgoing packets and drop packets that are larger than the maximum possible WireGuard packet payload (maximum packet size - WireGuard header length) to avoid crashes with super-sized packets.

• Update dependencies to the latest versions (pyo3 v0.17, pyo3-asyncio v0.17, pyo3-log v0.7), now that pyo3-asyncio v0.17 was released with pyo3 v0.17 support.
• Switch back from patched version of pyo3-asyncio to the official releases, since v0.17 incorporates our patch.

• Fix a race condition in the shutdown code that could cause shutdown to never happen.
• Make logger setup more robust and only try to initialize once.

• Make failures to initialize the Rust -> Python logger non-fatal.

• Temporarily use a patched version of pyo3-asyncio to fix a race condition in the handling of Python Futures which caused frequent race conditions.
• Implement is_closing(self) -> bool method on TcpStream to match asyncio.StreamWriter.

• Simplified GitHub actions for CI and publishing wheels to PyPI.
• Failed sub-tasks are now handled immediately and cause a server shutdown instead of silently returning and only yielding an error when shutting down the server manually.

• Fix building binary wheels for aarch64-unknown-linux-gnu.

• Fix test client to only send valid packets.

• Adapt the test client to handle EAGAIN gracefully.

• Split test client into separate workspace crate to speed up builds and hopefully fix them on macOS.

• Revert addition of ChecksumCapabilities::ignored to the virtual network device. This change in v0.1.1 completely broke TCP connection handling.

• Added a simple test client binary (mitm-wg-test-client).
• Ignore TCP checksums in network device code, they are already checked in other places.
• Port to boringtun v0.5.

Initial Release.
