[Unreleased]

[1.2.2.0] - 2022-09-22

Changed

  • Upgrade the code and build instructions to use Visual Studio 2022 instead of 2019.

Security

  • Fix incomplete validation of input buffers that could result in out-of-bounds reads. Fixes 2022 Mullvad app audit issue item MUL22-01.

[1.2.1.0] - 2022-04-19

Security

  • For non-excluded DNS traffic, evaluate all appropriate filters within the DNS sublayer when a soft permit has been applied in a higher-priority sublayer.

[1.2.0.0] - 2022-01-10

Changed

  • Update build and release procedure to remove support for pre-Windows 10 systems.

Fixed

  • Ensure IOCTL requests are always processed on worker thread to prevent client from getting stuck inside DeviceIoControl API call.
  • Apply a soft permit on excluded traffic, rather than a hard permit. This allows firewall filters added by other software (e.g. Windows Defender) to evaluate and block traffic.

[1.1.1.0] - 2021-06-04

Fixed

  • Correct unfortunate application of NT_ASSERT, the illustrious. Critical logic that updates the process tree was being omitted from release builds.

[1.1.0.0] - 2021-05-26

Changed

  • Use improved model to determine when to split traffic. This has the following effects:
    • TCP client sockets connecting to localhost can now be used successfully.
    • Routing now works as expected, e.g. when being connected to multiple LANs.

[1.0.2.0] - 2021-05-04

Changed

  • Use less strict security descriptor on device object. The previous SD could e.g. prevent uninstallation of the driver, since uninstallers typically are not ran as SYSTEM.

Fixed

  • Various minor code changes to improve both source code and runtime consistency.

[1.0.1.0] - 2021-03-12

Fixed

  • Force reauthorization in WFP if state has changed but WFP was not updated in the process.

[1.0.0.0] - 2021-03-10

Initial release.
