[PATCH 0/1] MR10445: tomcrypt: Treat FreeBSD like Linux
by Gerald Pfeifer (＠gerald) June 9, 2026

June 9, 2026

We are currently seeing ``` libs/tomcrypt/mpi.c:5785:24: error: implicit declaration of function ‘arc4random’ [-Wimplicit-function-declaration] 5785 | d |= ((mp_digit) arc4random()); | ^~~~~~~~~~ ``` even if including <stdlib.h> and setting various standard defines, so simply don't treat FreeBSD specially and go with the Linux code. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10445

[PATCH 0/1] MR7475: winewayland: Ignore relative motion while pointer lock is deactivated.
by Attila Fidan (＠atticf) June 8, 2026

June 8, 2026

If the lock is deactivated, mouselook won't work properly, and the user probably doesn't want mouselook to be active. For example: * if the user is making their compositor inhibit constraints to temporarily prevent applications from disrupting pointer movement. * if the keyboard is unfocused on the window, the lock is almost certainly deactivated.

[PATCH v4 0/2] MR9299: ole32, combase: Add tests for COM context switching and delayed marshaling.
by Vibhav Pant (＠vibhavp) June 6, 2026

June 6, 2026

When `RoGetAgileReference` is used with `AGILEREFERENCE_DELAYEDMARSHAL`, the returned `IAgileReference` also contains a reference to the apartment the object belongs to. Thus, when `IAgileReference::Resolve()` gets called, the object will get marshaled inside the owning apartment, not the caller's apartment. This seems to be made possible by the `IContextCallback` interface. It provides a way to (ab)use the marshaller to execute arbitrary code inside a COM context, which is an additional bit of state nested inside apartments. An apartment can contain multiple COM contexts, and the standard marshaller will keep track of which context a marshaled interface is bound to. All method calls through that marshalled pointer will be wrapped around a context-switch, even when the caller is in the same apartment. Additionally, creating an instance of the class `CLSID_IContextCallback` allows us to create new contexts inside an apartment. C++/WinRT makes use of `IContextCallback` to [implement support for C++ coroutines ](https://github.com/microsoft/cppwinrt/blob/ebace4abb8f48b6b9a612e8b84667e6044976a47/strings/base_coroutine_threadpool.h#L51)(co_await, et al) inside application STA code. Another use of COM contexts seems to be the UI code in WinRT applications, where certain objects can only be `Released`/destructed from the apartment they were created in. (I was able to find another instance of `IContextCallback` usage in the wild [here](https://github.com/Open-Shell/Open-Shell-Menu/blob/4ebeadd949d0550642…, to get an `IAccessible` implementation that has apartment-affinity). -- v4: ole32/tests: Add tests for IContextCallback::ContextCallback and CoDisconnectContext. combase/tests: Add tests for delayed marshaling of objects with apartment affinity. https://gitlab.winehq.org/wine/wine/-/merge_requests/9299

[PATCH v7 0/2] MR8073: ntdll: Unbreak new wow64 mode on FreeBSD.
by Alexander Shaikhulin (＠shkhln) June 5, 2026

June 5, 2026

1. For %fs/fsbase the patch follows the macOS logic with LDT descriptor registration and Linux with switching. One notable difference is that on 32->64 transition we set %fs to GSEL(GUFS32_SEL, SEL_UPL) before restoring fsbase, otherwise FreeBSD will just revert it by reloading the selector [at the first opportunity](https://github.com/freebsd/freebsd-src/blob/5673462af5330df207…. GSEL(GUFS32_SEL, SEL_UPL) is the default %fs value on FreeBSD and is special-cased to save/restore actual fsbase value to/from PCB. 2. I was told we could get rid of fsbase glitches in signal handlers by blocking signals with [sigfastblock(2)](https://man.freebsd.org/cgi/man.cgi?query=sigfastblock) between %fs reset to the default value and fsbase reset to pthread_teb. This is currently a part of internal API for libthr, which could be exposed as pthread_signal_block_np for Wine. I'm on the fence whether it's worth it. 3. I fully admit I have no idea what registers are worth preserving around fallback sysarch(AMD64_SET_FSBASE) syscalls and whether it's appropriate to push those registers to stack. ("Kernel" stack should be fine, I assume?) Syscalls definitely clobber r8-r11. 4. For %ss see https://lkml.org/lkml/2015/4/24/216. FreeBSD doesn't have a similar workaround in the kernel, so it goes into Wine. -- v7: ntdll: Work around AMD SYSRET SS descriptor behavior on FreeBSD. ntdll: Unbreak new wow64 mode on FreeBSD. https://gitlab.winehq.org/wine/wine/-/merge_requests/8073

[PATCH 0/1] MR10517: wined3d: Don't use texelFetchOffset() for buffers and multi-sample textures.
by Francisco Casas (＠fcasas) June 2, 2026

June 2, 2026

The TexelFetchOffset() GLSL function is not defined for sampler2DMS, sampler2DMSArray and samplerBuffer, so we get the following wined3d_debug_callback errors when emiting them: "0:56(9): error: no matching function for call to `texelFetchOffset(sampler2DMS, ivec2, int, ivec2)'; candidates are:". "0:56(9): error: vec4 texelFetchOffset(sampler1D, int, int, int)". ... "0:56(9): error: uvec4 texelFetchOffset(usampler2DArray, ivec3, int, ivec2)". "0:56(9): error: type mismatch". This happens when wined3d with the opengl backend is used to run Dishonored 2. To fix this, we emit TexelOffset() for these samplers instead, and just add (+) the offset to the position parameter. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10517

[PATCH 0/1] MR9866: Revert "ntdll: Switch to CLOCK_BOOTTIME for monotonic counters when available."
by Rémi Bernon June 2, 2026

June 2, 2026

This reverts commit 3d373e452388b60bea9dca6d5c4cf3f8b20a0c54. CLOCK_MONOTONIC_RAW is used in vulkan to correlate QPC timestamps, and there's no equivalent of CLOCK_BOOTTIME there. Using CLOCK_BOOTTIME for QPC breaks the vulkan side with no proper way to fix it. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9866
