[PATCH 0/5] MR8540: kernelbase: Handle reparse points in some high-level functions, part 1/2.
by Elizabeth Figura (＠zfigura) July 31, 2025

July 31, 2025

These do not do anything currently, since we don't support FILE_OPEN_REPARSE_POINT on the Unix side yet. However, they are correct, as demonstrated by the recently committed tests, and it seems prudent to get these out of the way for now. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8540

[PATCH v2 0/2] MR8632: dsound: Zero IDirectSoundBufferImpl_Lock out params if the arguments are invalid.
by Alfred Agrell (＠Alcaro) July 31, 2025

July 31, 2025

https://store.steampowered.com/app/638930/Dal_Segno/ occasionally calls IDirectSoundBuffer::Lock() with writecursor == buflen and writebytes == 0. This is illegal, so Lock() returns DSERR_INVALIDPARAM - but the game doesn't notice, and does a memcpy to fill the returned buffer. On native, the out params are zeroed on failure, so the memcpy ends up doing the right thing. On Wine, the out params are left unchanged on failure, resulting in memcpy(STACK GARBAGE, src, STACK GARBAGE); after a few minutes of gameplay or idling (when the size isn't coincidentally zero), it crashes. ``` 6518.932:0130:01b8:trace:dsound:IDirectSoundBufferImpl_GetCurrentPosition (01FF9BC0,090BEE94,00000000) 6518.932:0130:01b8:trace:dsound:IDirectSoundBufferImpl_GetCurrentPosition playpos = 20674080, writepos = -1, buflen=20709376 (01FF9BC0, time=6518932) 6518.932:0130:01b8:trace:dsound:IDirectSoundBufferImpl_Lock (01FF9BC0,20709376,0,090BEEA0,090BEE90,090BEE9C,090BEE98,0x00000000) at 6518932 6518.932:0130:01b8:warn:dsound:IDirectSoundBufferImpl_Lock Invalid parameter, writecursor: 20709376 >= buflen: 20709376 6518.932:0130:01b8:trace:seh:dispatch_exception code=c0000005 flags=0 addr=00444C5C ip=00444c5c 6518.932:0130:01b8:trace:seh:dispatch_exception info[0]=00000001 6518.932:0130:01b8:trace:seh:dispatch_exception info[1]=0042d0b5 6518.932:0130:01b8:warn:seh:dispatch_exception EXCEPTION_ACCESS_VIOLATION exception (code=c0000005) raised 6518.932:0130:01b8:trace:seh:dispatch_exception eax=0000008e ebx=7aa539c0 ecx=00000008 edx=00000000 esi=004dcf10 edi=0042d0b5 6518.932:0130:01b8:trace:seh:dispatch_exception ebp=090bee68 esp=090bee60 cs=0023 ss=002b ds=002b es=002b fs=0063 gs=006b flags=00010246 ``` (The game is poorly written in several other ways - the segfault is caught in a SEH handler that also segfaults, repeat until stack overflow; it repeatedly unlocks critical section 004A4A28, which nothing ever locks; there's a homemade spinlock implementation at 0042CAB2; probably some more weirdness I didn't discover. But those have little or no user-visible impact, they just look ugly in the PROTON_LOG and/or game disassembly. Let's ignore them.) ...is there such a thing as too many tests?

[PATCH 0/1] MR8504: winemac: Get rid of unnecessary child window views.
by Rémi Bernon July 31, 2025

July 31, 2025

I think this dates from a time where every window had its own window surface, and unless I'm missing something this isn't needed anymore. My intention is to refactor the client surfaces, so that they can be manipulated directly from win32u, and unify GL/VK client surfaces. This would make the code simpler, in preparation for that. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8504

Ah, interesting. Thanks for looking in to that. I can't speak to any of that, really - I'm not very familiar with winegstreamer at all. I was more wondering if we needed to explicitly set `byte-stream`, and maybe we don't?: tclem/wine!8. Not sure if the tests cover the initial issue you were addressing though. And I guess if it fixates to AVC but doesn't have the required `codec_data` then maybe `byte-stream` is the only option. But like I said, that has broken h.264 on macOS. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8532#note_111746

[PATCH v4 0/1] MR8605: winebus: Do not touch autocenter on device init and device reset
by Tomasz Pakuła July 31, 2025

July 31, 2025

FFB Autocenter introduced in https://gitlab.winehq.org/wine/wine/-/merge_requests/4911 had one major misunderstanding. The USB PID standard doesn't actually define any explicit way to autocenter a device. One could of course use the spring effect with a deadzone of 0 and dead band of 0. This is what I'm actually working on for the Linux PID driver (spring + friction/damper). Some devices implement autocenter in firmware when they receive the DC Disable Actuators command. Very few, if not just one, implement this weird autocenter effect on slot 1. This is, from what I can gather, only implemented on the MS SideWinder joystick(s) and the Windows' USB PID driver is created around these devices. Windows PID driver is a bit out of spec, is quite permissive when it comes to fields missing in the descriptor (basically, only effect types and their effect type blocks are optional). Another thing it does is handling of this out-of-spec autocentering for their joysticks. Funnliy enough, the creator of the Linux PID driver based the initial code on testing with MS Sidewinder so it's autocentering is supported. This is where the autocentering mentioned in the MR comes from. It's not the directinput api that does it but the Windows PID driver. As such, autocentering on reset should be left to the drivers, not handeled by Wine. SDL lacks full reset support and Linux is even more barebones, whre it's not even possible to query the device state, effects etc (something I'm working on slowly). As such, when games send out RESET to prepare the device, the device starts autocentering for no good reason and the effect is not removed once other effect are uploaded and played which would be the case for MS sidewinder. In any case, even Windows in inconsistent and I think the directinput documentation has some errors. directinput ffb api is largely based on USB PID but: ![image](/uploads/6548386550b874d2e5548f35f7fe76b0/image.png) ![image](/uploads/851484a555c744c6791d48b3fd194e91/image.png) Testing with my Moza Racing R9 wheelbase, the DC Reset PID command is sent, but there's no DC Disable Actuators in sight. The games still call reset then enable actuators though. tl;dr Set autocentering to 0 instead of max value when DISFFC_RESET is received to remove the unwanted autocenter behavior.

I can see in your patch that it's probably more complicated (the error is always the same if I move test_ADORecordsetConstruction before test_ConnectionPoint). Anyway, it's probably better to run ConnectionPoint tests first. Another option is to try to investigate what's happening there but I'm not sure if it's worth the effort. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8683#note_111715

I think it would be best to move these tests before other tests instead (and add comment mentioning that this should be the first test). The function returns error returned by last function that failed (or E_FAIL if there was none). The tests can be easily modified so ConnectionPoint tests return different error. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8683#note_111714
