[PATCH 0/1] MR7916: kernel32: Fixed MulDiv's inconsistencies with Windows.
by Shavit Yosef (＠shavitush) 27 Apr '25

27 Apr '25

`MulDiv` doesn't match the correct Windows behavior for the function, which actually differs in some edge cases for 32-bit and 64-bit. Test case: ```c MulDiv(1, 0x80000000, 0x80000000); // WINE - both 32-bit and 64-bit: 0 // Windows (32-bit/kernel32.dll): 2 // Windows (64-bit/kernelbase.dll): -1 ``` On Windows 32-bit, this would return 2. On 64-bit, it'd return -1. However, on WINE, this call would return 0 for both 32-bit and 64-bit. This discrepancy was previously abused by threat actors to detect if the application runs under WINE. --- On Windows, `MulDiv` has a different implementation for 32-bit (from `kernel32.dll`) and 64-bit (leveraged to `kernelbase.dll` from `kernel32.dll`). After adjusting the 64-bit code to be an exact replica of the original code from `kernelbase.dll`, it'd still return the incorrect value due to Microsoft's code having undefined behavior with negation. It could be avoided with `-O0` but I opted into rewriting it with the undefined behavior to be, well.. defined. To clarify, the original code from Microsoft has a bug (logically, at least). But WINE is supposed to have matching behavior so we can run Windows programs as intended. The 32-bit version of `MulDiv` in Windows has a more complicated bug; I've documented it in the code. --- This is my first contribution to WINE - I cannot find any `CONTRIBUTING.md` or similar file with guidelines so I did my best to follow the convention of other merge requests. I've added unit testing for `MulDiv` to ensure there won't be a regression in the future. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7916
