[PATCH v2 0/3] MR10277: Draft: user32: Make static control internal data private.
by Piotr Caban (＠piotr) March 9, 2026

March 9, 2026

Fixes adding account in Quicken Classics. The application depends on GetWindowLong(static_hwnd, 0) returning 0. The implementation uses NtUserSetWindowFNID that is not compatible with Windows. According to information available on the Internet the function takes control id. Since the control id's are not documented and may change between Windows versions I have used the argument to pass private data range instead. Thanks to it we don't have to hardcode it on win32u side. -- v2: user32: Make static control internal data private. user32: Test static control extra window data access. ntdll: Read last error from wow teb in unixlib RtlGetLastWin32Error. https://gitlab.winehq.org/wine/wine/-/merge_requests/10277

[PATCH 0/1] MR10264: winmm: Don't access WAVEFORMATEXTENSIBLE if cbSize is too small (ASan).
by Bernhard Übelacker March 9, 2026

March 9, 2026

In `WINMM_MapDevice` the pointer `device->orig_fmt` is casted to a WAVEFORMATEXTENSIBLE into `fmtex`, even when no additional memory got allocated, which is marked by `cbSize` being zero. Therefore ASan got triggered when `fmtex->SubFormat` gets read by `IsEqualGUID`. CC: @giomasce (I currently cannot point to a specific commit, but this may also be related to the recent changes?)

[PATCH v7 0/3] MR10232: ntdll: Avoid exposing non-user rsp in normal syscall return path
by Hoshino Lina (＠hoshinolina) March 9, 2026

March 9, 2026

When rsp is outside the kernel stack, the SIGUSR1 handler considers the context "out of syscall" and reports the real register values to wineserver. rsp pointing into the syscall frame is used for iret returns. Commit 0a5f7a710365 moved this earlier in the return path, creating a window in the regular direct return path where rsp points neither to the kernel stack, nor to the expected user stack. When a thread is interrupted by SIGUSR1 within this window, this exposes a bogus stack pointer to GetThreadContext(), breaking the garbage collector in Unity applications. Fix the regression by first switching to the real user stack (needed so we don't break things by touching other registers), then, only if an iret path is coming up, switching to the syscall frame pointer. This fixes the regression introduced by 0a5f7a710365, since GetThreadContext() will now observe the proper stack pointer during regular syscall returns. Further work would be needed to solve other corner cases and ensure that the register context returned by GetThreadContext() behaves exactly as on Windows (with no kernel-mode context info ever returned), but that is a larger/more invasive change. Fixes: 0a5f7a710365 ("ntdll: Switch to the user stack before restoring the %fs register.")

[PATCH v3 0/2] MR9857: ntdll/unix: Reimplement fill_vm_counters() for macOS.
by Jactry Zeng (＠jactry) March 9, 2026

March 9, 2026

On Windows, PagefileUsage represents the total private memory committed by a process, includes both resident memory in RAM and pages swapped to the disk. On macOS, virtual_size is misleading as it represents the total reserved address space, which is often vastly larger than actual usage; for example, it can be 40+GB when a program was alloced about 4GB memory on a machine with 16GB RAM (tested on Intel macOS 15.7.2 and Apple Silicon macOS 26.2). In order to make it closer to the Windows metric, using the sum of TASK_VM_INFO.internal (resident private memory in RAM) and swapped pages (includes both compressed memory in RAM and pages that were swapped to the disk) from mach_vm_region_recurse() is more correct. I also use the sum of TASK_VM_INFO.internal and TASK_VM_INFO.compressed (compressed memory, and still in RAM) as a fallback when mach_vm_region_recurse() fails; however, this doesn't include that the memory has been compressed and swapped to the disk[0], but it is still correct relatively to the current implementation.

[PATCH 0/1] MR10272: iphlpapi: Swap the order of address families in call_families to process IPv4...
by Zhao Yi (＠Zhaoyi) March 9, 2026

March 9, 2026

A Ruby application obtains network adapter IP information by calling the **Win32_NetworkAdapterConfiguration** class. However, the order of IPv4 and IPv6 addresses retrieved on Windows differs from that retrieved when running on Wine, which causes Ruby applications running on Wine to malfunction. A test demo was written that calls the **Win32_NetworkAdapterConfiguration** class to obtain network adapter information. It was run on Windows and on Wine respectively, and the results are as follows.

[PATCH v8 0/3] MR10114: msi: Handle unusual installer files (padding, malformed strrefs)
by Theodoros Chatzigiannakis (＠TChatzigiannakis) March 9, 2026

March 9, 2026

This PR addresses two issues that I observed preventing the Native Instruments Kontakt Player MSI (and other MSI files from the same vendor) from successfully finishing: 1. Some installers contain padding for 4-byte alignment of table streams. * Proposed fix: We relax Wine's parsing to allow for such padding. 2. Some installers declare that they have 3-byte strrefs, but the data actually contains 2-byte strrefs. This looks like a malformed MSI to me, and Wine correctly rejects them currently. The regression tests in this PR indicate that Windows in CI (test-win10-21h2-\*) is reading garbage as well. However, NI ships these MSI files, which implies that somehow the installation successfully completes on Windows machines nevertheless. * Proposed fix: We explicitly detect and correct this particular mismatch at load time of the MSI, in order to be able to complete the installation under Wine as well. --- The above are technically separate issues, but they affect the same software in similar ways, so I opted for one PR. Please me know if I should split them. --- Quick repro hint: Native Instruments offers a program called Native Access (which acts as an installation hub on the user's machine). On user request, NA downloads and launches the affected MSI files in the background. If you try to repro, a couple of things to watch out for: 1. NA seems to always report a successful installation, even when the underlying MSI fails to complete (and therefore nothing is installed). This PR does nothing to address this false positive, as it is most likely a logic bug in the hub or installation orchestration. 2. To observe/examine the underlying MSI files (including the fix presented here), you'll need to grab them after NA downloads and extracts them on your machine (or find manual/direct downloads on the NI website, where applicable) --- _Disclaimers for reviewers:_ * _AI was used while tracking down the issues and coming up with fixes._ * _I am not affiliated with Native Instruments, I'm just a user._ -- v8: msi/tests: Add regression tests for table stream padding and mismatched string refs. https://gitlab.winehq.org/wine/wine/-/merge_requests/10114

[PATCH 0/2] MR10269: qcap: Fix Smart Tee negotiation and V4L WoW64 media type marshaling.
by zhineng cao (＠LilFishyChan) March 9, 2026

March 9, 2026

## Summary This work started from a real-world regression: in VRChat, the camera could not be used. After investigation, VRChat was found to use DirectShow for camera capture/preview. The issue was then narrowed down to qcap behavior differences, and fixes were implemented in source code to align with native behavior. This MR includes: 1. Smart Tee preview RGB32 negotiation fix. 2. V4L wow64 media type marshaling fix. These changes are expected to resolve this class of DirectShow camera compatibility issues. ## Root cause and approach - Application symptom: VRChat camera path failed. - API path: DirectShow camera pipeline. - Scope narrowed to qcap Smart Tee preview negotiation and wow64 media-type marshaling in V4L backend. - Implemented behavior-aligned fixes and corresponding conformance tests. ## Validation - Native Windows behavior was probed and used as baseline during test alignment. - `qcap_test.exe smartteefilter`: **488 tests, 0 failures** (i386/x86_64) - `qcap_test.exe videocapture`: **754 tests, 0 failures** (i386/x86_64) - Functional app check: `AMCap.exe` preview opens camera successfully and image display is normal. ## Expected impact This MR is expected to fix/mitigate similar cases where DirectShow-based applications fail to initialize or preview camera streams under Wine. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10269
