[PATCH v2 0/7] MR10099: winebth.sys part 14: Create PDOs for GATT services.
by Vibhav Pant (＠vibhavp) 24 Feb '26

24 Feb '26

GATT services are exposed with the `GUID_BLUETOOTH_GATT_SERVICE_DEVICE_INTERFACE` interface, and are needed to implement methods like [`BluetoothGATTGetCharacteristicValue`](https://learn.microsoft.com/en-us/windows/win32/api/bluetoothleapis/nf-bluetoothleapis-bluetoothgattgetcharacteristicvalue) (the first argument needs to be a handle to a service). Additionally, methods like [`BluetoothGATTGetCharacteristics`](https://learn.microsoft.com/en-us/windows/win32/api/bluetoothleapis/nf-bluetoothleapis-bluetoothgattgetcharacteristics) accept `HANDLE`s to both LE devices and services as the first argument. -- v2: bluetoothapis: Implement BluetoothGATTGetCharacteristics for GATT service handle objects. winebth.sys: Add debug helper for DBusMessageIter values. bluetoothapis/tests: Add tests for calling BluetoothGATTGetCharacteristics with a GATT service handle. winebth.sys: Implement IOCTL_WINEBTH_LE_DEVICE_GET_GATT_CHARACTERISTICS for GATT service PDOs. https://gitlab.winehq.org/wine/wine/-/merge_requests/10099

Re: [PATCH v28 0/1] MR9442: comctl32/treeview: check for child item before SendExpanding
by Thomas Csovcsity (＠thc13) 24 Feb '26

I had a deeper look at the app behavior and tried to write a small app reproducing it without success. Following code flow and app behavior triggers the error, but i am not sure which additional conditions are necessary to reproduce this. - the app is actively deleting child items from node, after receiving TVN_ITEMEXPANDINGW - without changing `item->state |= TVIS_EXPANDED;` the next mouse click triggers a toggle, but this code still assumes that the node is expanded, therefore it takes the wrong branch. If i follow the rules https://gitlab.winehq.org/wine/wine/-/wikis/Clean-Room-Guidelines, i am stuck here to write a small app to reproduce the bug or to write a test for this case. Any hint is appreciated or please close this MR otherwise with a note. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9442#note_130401

[PATCH v4 0/3] MR9874: wineandroid.drv: experimental bring-up fixes for Android 7.1.x
by Twaik Yont (＠twaik) 24 Feb '26

24 Feb '26

Requires #10067, fixup/followup to e0d3683d8947cd9a3cb20acdf69091b183a90861 and 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc. #### Note on authorship and language This text was translated into English and structured with the assistance of ChatGPT. The author is not a native English speaker and may struggle with written technical English; any wording issues are unintentional. #### Description This merge request is an experimental attempt to bring wineandroid.drv back to a minimally functional state on Android 7.1.x. The current Android support appears to have bit-rotted over time, likely due to a combination of internal contract changes in Wine, toolchain and NDK evolution, and the absence of continuous Android testing. The changes proposed here aim to re-establish a working baseline and make the regressions more concrete and easier to reason about. #### Test environment and context All testing so far was performed on Android 7.1.2 x86 images from the Android-x86 project, published on osboxes.org ([link](https://www.osboxes.org/android-x86/)) The primary target is i386 Wine running on x86 Android userspace. Because no up-to-date official Android build scripts were available, Wine was built using Termux as an unsupported but convenient environment for rapid testing. The Java part (WineActivity and related glue code) was built with `sharedUserId = com.termux` purely for convenience (filesystem access and faster prototyping). **Termux is explicitly not considered a supported environment and is mentioned only to provide context for the testing setup.** The build uses Android NDK r29. Since the last known functional Android Wine builds, the NDK and linker behavior have changed multiple times, including symbol visibility and relocation handling. These changes appear to have directly affected several failure modes described below. There is also a known issue with wine-preloader producing excessively large binaries under recent toolchains; a workaround exists but is not included here and is mentioned only as additional context. #### Scope of changes This merge request currently modifies only Android-specific code: - `wineandroid.drv` (native code and Java glue, including WineActivity) - android-only paths in `dlls/ntdll/unix/loader.c` No non-Android platforms are affected. #### Summary of resolved issues 1) Desktop initialization ordering regression After recent `CreateDesktopW`-related changes, `ANDROID_CreateDesktop` started running before the DESKTOP window was created. The Java glue assumed the opposite order. The fix splits desktop initialization into two phases (view setup first, desktop window attachment later via an explicit is_desktop flag) and corrects the `ANDROID_CreateDesktop` success return value. 2) Rendering stalls and `USER lock assertion` Occasional crashes with: ``` err:system:user_check_not_lock BUG: holding USER lock ``` A full memory barrier was added in the dequeue path to avoid a likely memory ordering issue. Additionally, a guard was added for a `NULL` buffer returned on successful dequeue. 3) Early startup failure in `virtual_alloc_first_teb` Wine frequently failed with: ``` err:virtual:virtual_alloc_first_teb wine: failed to map the shared user data: c0000018 ``` `virtual_init()` is now called from `JNI_OnLoad()` to reduce the likelihood of the JVM reserving the required address range before Wine initializes its virtual memory subsystem. #### Remaining issues - Window focus handling is partially broken: windows receive focus on click, but are not always raised to the front. - Despite the available desktop area being larger (e.g. 1024x696), Wine consistently reports a display resolution of 800x600. #### Limitations Wine on Android stopped functioning entirely starting with Android 8. As a result, all testing so far has been limited to Android 7.1.x. No claims are made about behavior on newer Android versions. #### Out of scope This merge request intentionally does not attempt to: - redesign IPC mechanisms - introduce new Android integration models - address Android 8+ compatibility The sole goal is to re-establish a minimally working baseline on Android 7.1.x and enable informed discussion about what regressed and how to proceed. **This is my first contribution to Wine, and I am aware that some parts of this analysis or implementation may be flawed. I would be grateful for any review comments or suggestions.** <details> <summary>Also, the screenshot of the working prototype.</summary> ![image](/uploads/d2420de5d9b3b95b8f5184f8a60550d0/image.png){width=743 height=600} </details> -- v4: ntdll: call virtual_init from JNI_OnLoad to avoid early virtual_alloc_first_teb failure Wineandroid: Sanitize dequeueBuffer result and reject missing buffers. https://gitlab.winehq.org/wine/wine/-/merge_requests/9874
