[PATCH v20 0/2] MR9632: sxs: avoid uninitialised len_name length
by Hans Chen (＠hans.chen) 12 Dec '25

12 Dec '25

The `redirect_data->clrdata_len` [is unset in /dlls/ntdll/actctx.c#L4411-4412](https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/ntdll/actctx.c?ref_type=heads#L4411-4412) when using registration-free COM in C# NET code. Program.cs ```C# //... Guid guid = Guid.Parse("COM clsid"); Type type = Type.GetTypeFromCLSID(guid, true); var instance = Activator.CreateInstance(type)); //... ``` App.manifest ```xml <assembly> <file name="ExampleCOM.dll"> <comClass description="ExampleCOM" progid="ExampleCOM" clsid="{COM clsid}" threadingModel="Free"/> </file> </assembly> ``` The above C# code gets this error on its second line. ```Shell System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. ``` This is because `len_name` is uninitialized when calling `memcpy(ret_strings, ptr_name, len_name);` in `SxsLookupClrGuid`, which is fixed in this MR. -- v20: add comClass to manifest https://gitlab.winehq.org/wine/wine/-/merge_requests/9632

It isn't inherently bad, but it can be if e.g. the application goes out of its way to `Initialize()` its own `AudioClient`s in the same session. Also it's not what native does. The test hack I attached to the bug shows that native `IMFMediaEngine` doesn't modify the session-wide master volume. I have a cleaned-up version of the same test that requires !9756 to not crash on Wine. I could modify the test to skip on Wine for the time being. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9755#note_125494

[PATCH v3 0/2] MR9732: ntdll: Support FSCTL_DUPLICATE_EXTENTS_TO_FILE
by nikita pushkarev (＠strudelll) 11 Dec '25

11 Dec '25

Implement FSCTL_DUPLICATE_EXTENTS_TO_FILE handling in ntdll on Linux by wiring the IOCTL to FICLONERANGE/FICLONE where available and returning STATUS_INVALID_DEVICE_REQUEST otherwise. Adds the necessary constants/types when missing. -- v3: ntdll: Advertise FILE_SUPPORTS_BLOCK_REFCOUNTING when reflink is supported. https://gitlab.winehq.org/wine/wine/-/merge_requests/9732

[PATCH v2 0/1] MR9744: win32u: Use PostScript Name as fallback when Unique Name is not found in freetype name table
by Jade Pfeiffer (＠Cthuflu) 11 Dec '25

11 Dec '25

This patch should remedy an issue with `freetype_set_outline_text_metrics` failing to read a full name for some fonts that don't have a unique name entry in their name table. For example, some Material fonts from Google that DON'T have a unique name entry. | Font | NameID | StringName | |-------------------------|----------------|-------------------------------| | Material Icons Outlined | 0 (Copyright) | (Google Copyright Text) | | | 1 (Family) | Material Icons Outlined | | | 2 (Style) | Regular | | | 6 (PostScript) | MaterialIconsOutlined-Regular | | Material Icons Round | 0 (Copyright) | (Google Copyright Text) | | | 1 (Family) | Material Icons Round | | | 2 (Style) | Regular | | | 6 (PostScript) | MaterialIconsRound-Regular | | Material Icons Sharp | 0 (Copyright) | (Google Copyright Text) | | | 1 (Family) | Material Icons Sharp | | | 2 (Style) | Regular | | | 6 (PostScript) | MaterialIconsSharp-Regular | | Material Icons Two Tone | 0 (Copyright) | (Google Copyright Text) | | | 1 (Family) | Material Icons Two Tone | | | 2 (Style) | Regular | | | 6 (PostScript) | MaterialIconsTwoTone-Regular | This (mostly) follows [Apple's TrueType name table docs](https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap… for what names should be included for a font (aside from missing a full name entry). While this patch is based on Apple's documentation, it should be reasonable that the PostScript name is treated as an acceptable fallback for a unique name: `"If two fonts are installed with the same PostScript name, Apple platforms treat them as duplicates and only one will be available for use."` -- v2: win32u: Full Name as fallback for Unique Name https://gitlab.winehq.org/wine/wine/-/merge_requests/9744
