[PATCH 0/1] MR2468: ntdll: Don't report user (PE) stack via pthread_attr_setstack().
by Jinoh Kang (＠iamahuman) 30 Mar '23

30 Mar '23

Today, NtCreateThreadEx() passes to pthread_attr_setstack() an address range that spans both the user (PE) stack and the kernel (Unix) stack. pthread_attr_setstack() accepts an address range that will be used as the initial stack area for the thread created by pthread_create(). It is often assumed that the initial stack will be available for the entire duration of the thread's lifetime. This assumption, however, conflicts with how Win32 fibers operate. Fiber APIs allow the thread's initial stack to be freed before the thread exits, or kept alive beyond the point of thread's termination. This allows the lifetime of the thread's initial stack to be shorter or longer than the originating thread's lifetime. This is possible because each fiber has its own stack and context, and ConvertThreadToFiber() transfers the current thread's stack to a new fiber. This specifically causes problems in Glibc v2.31 and earlier. These Glibc versions have a bug where madvise(2) with the MADV_DONTNEED flag is called on the initial stack area on thread exit, even when the stack was user-supplied (via pthread_attr_setstack). Therefore, the kernel may zero out any portion of the initial stack at any time after the originating thread terminates, even if the stack no longer belongs to the current thread (either freed and reallocated, or owned by a fiber). This may ultimately lead to memory corruption. Fix this by only passing the syscall (kernel) portion of the stack to pthread_attr_setstack(). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2468

[PATCH v2 0/1] MR2471: winegstreamer: In video_processor, activate a videoflip converter.
by eric pouech (＠epo) 30 Mar '23

30 Mar '23

The app I'm considering opens a video_processor on its own, with a NV12 format on input and a ARGB32 format on output. Tested on Windows: the samples are flipped vertically. While Wine keeps them untouched. So added a videoflip in the video processor to be activated when needed. Current activation is based on RGB vs non RGB input/output formats. Set as draft as if somehow related to MR!2159. Comments welcomed.

[PATCH 0/1] MR2537: include: Add windows.ui.core.idl file.
by Mohamad Al-Jaf (＠maljaf) 30 Mar '23

30 Mar '23

Needed for mingw Firefox build. It looks like CoreDispatcher was added as a forward declaration for `ICompositionObject`: https://searchfox.org/mozilla-central/source/taskcluster/scripts/misc/mingw… However, just having `interface ICoreDispatcher;` alone does not generate the IUnknown methods. I don't know if commenting out the functions is acceptable. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2537

[PATCH 0/3] MR2536: services: Change running service state once its process dies.
by Paul Gofman (＠gofman) 30 Mar '23

30 Mar '23

Fixes Epic Online Services update hanging when the service needs to be restarted (a helper process is waiting for either service's mutex to be available or QueryServiceStatus to tell that the server is stopped after the service had just exited the process without notifying service control manager). It seems to me that using a job object is much simpler than the other ways (like waiting on multiple process handles and managing process addition and deletion in the waiters list). I tested that on real up to date Windows 10 machine and there the process has the job object which object has JOB_OBJECT_LIMIT_BREAKAWAY_OK | JOB_OBJECT_LIMIT_SILENT_BREAKAWAY_OK limit flags (and only those). That job has also the other service processes in it but not services.exe itself. However, for some reason on any Testbot machine that is not the case and IsProcessInJob() reports that the process doesn't have a job. But since I do see that job on a real machine I think using job object here is fine. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2536
