[PATCH v2 0/3] MR9874: Draft: wineandroid.drv: experimental bring-up fixes for Android 7.1.x (discussion starter)
#### 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> {width=743 height=600} </details> -- v2: ntdll: call virtual_init from JNI_OnLoad to avoid early virtual_alloc_first_teb failure wineandroid: add memory barrier in dequeue path and guard against NULL buffer wineandroid: fix desktop init ordering after CreateDesktopW changes https://gitlab.winehq.org/wine/wine/-/merge_requests/9874
From: Twaik Yont <9674930+twaik@users.noreply.github.com> Follow-up to e0d3683d8947cd9a3cb20acdf69091b183a90861 and 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc. After 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc, ANDROID_CreateDesktop is invoked from CreateDesktopW before the DESKTOP window is created. The previous code assumed the opposite order and tried to construct the desktop WineWindow from createDesktopWindow(), which no longer works. Split desktop initialization into two steps: create_desktop_view() now only sets up the Java TopView, and the actual desktop WineWindow is created later via create_window(), with an explicit is_desktop flag propagated through the IOCTL/JNI path. Also make ANDROID_CreateDesktop return TRUE on success. After e0d3683d8947cd9a3cb20acdf69091b183a90861 (effectively changing ANDROID_CreateDesktop return type from NTSTATUS to BOOL), returning 0 incorrectly indicated failure. Cache the desktop HWND in create_ioctl_window() to avoid repeated NtUserGetDesktopWindow() calls (to avoid unnecessary wineserver roundtrips).

From: Twaik Yont <9674930+twaik@users.noreply.github.com> Rendering could occasionally stall or hit: ``` err:system:user_check_not_lock BUG: holding USER lock ``` The issue was difficult to reproduce consistently and often disappeared when adding `TRACE` statements, suggesting a race or memory ordering problem. Inserting a full memory barrier (`__sync_synchronize()`) in `dequeueBuffer_DEPRECATED()` makes the problem reliably disappear in the tested setup. The exact root cause is still unclear (possible interaction between Wine changes, toolchain/code generation, or Android 7.1.x behavior). For now, treat this as a workaround to enforce proper memory ordering and avoid the USER lock assertion. Additionally, handle the case where `dequeueBuffer_DEPRECATED()` reports success but returns a NULL buffer, and bail out early instead of passing it to `gralloc_lock()`.

From: Twaik Yont <9674930+twaik@users.noreply.github.com> Wine frequently failed early during startup with: ``` err:virtual:virtual_alloc_first_teb wine: failed to map the shared user data: c0000018 ``` This appears to happen because the JVM can reserve address space that Wine later needs at a fixed address for the shared user data mapping. Initializing the virtual memory subsystem earlier reduces the chance of the JVM taking that range. Move `virtual_init()` from `wine_init_jni()` to `JNI_OnLoad()`, so it runs before other JNI activity during library load. Note that this change does not attempt to handle `virtual_init()` reentrance. When starting from an Activity `onCreate()` this is more likely due to the Android activity lifecycle, while calling it from `JNI_OnLoad()` is much less likely since it is only executed during library/class load.

I am not fully comfortable calling the MR “good enough” in its current form. For example, the desktop window should not be continuously recreated, and some of my changes are hiding an underlying issue rather than fixing it properly. My impression is that something changed in Wine over time, and in parallel there were compensating changes in winex11, while wineandroid was left behind. I was hoping to get pointers to specific changes that may have triggered these regressions, so I could implement proper compensating fixes on the wineandroid side. Doing a full bisect in this environment is realistically very difficult and time-consuming, and likely impractical for me right now. This concern applies to the overall set of issues addressed in the MR, not only the desktop window recreation. Done.

I agree. The barrier is only a workaround and I don’t want to push it as a real fix without understanding the root cause.
Unfortunately I haven’t been able to reliably diagnose where the USER lock is being held. Traditional debugging/backtraces are difficult here due to the mixed Wine PE + Android ELF + JVM environment (most stack traces are unusable). Do you have any advice on a good way to track down where the USER lock is acquired/held in this setup, or any preferred instrumentation approach you’d recommend? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9874#note_129878

I can have them.
I agree with your point about not adding memory barriers without understanding the underlying issue. After further testing, it looks like the barrier is not addressing the root cause. The failure is strongly timing-dependent: adding enough TRACE/logging in a few places often makes it disappear, and removing the software copy from the intermediate buffer into the Android rendering buffer also makes it disappear. So the barrier seems to at most mask the problem by changing timing, rather than fixing it. The crash `void user_check_not_lock(void): assertion "0" failed` consistently happens in `NtUserCreateWindowEx` after the `USER` lock was taken in `NtUserSetWindowPos`. I do not yet understand why the lock is still held at that point (missed release vs unexpected reentrancy vs call ordering / dispatch issue), but it is clearly a locking invariant violation and likely not specific to the Android backend. For debugging purposes, I modified the code to print two backtraces into `logcat` (Android logging subsystem): 1) the backtrace from the last `user_lock` call. 2) the backtrace from the failing `user_check_not_lock` call. Unfortunately, the resulting traces do not clearly indicate where the contract is being violated. <details> <summary>Log</summary> I added symbolization from in-process addresses to function names and source locations. However, these may not exactly match the current state of the upstream Git repository, since I had to apply a few additional local modifications to make the build sufficiently functional and capable of producing logs. ``` ---------------------------- PROCESS STARTED (7705) for package org.winehq.wine ---------------------------- 12:53:44.258 OpenGLRenderer I Initialized EGL, version 1.4

Ok, I was wrong about backtraces. I can have them. I agree with your point about not adding memory barriers without understanding the underlying issue. After further testing, it looks like the barrier is not addressing the root cause. The failure is strongly timing-dependent: adding enough TRACE/logging in a few places often makes it disappear, and removing the software copy from the intermediate buffer into the Android rendering buffer also makes it disappear. So the barrier seems to at most mask the problem by changing timing, rather than fixing it. The crash `void user_check_not_lock(void): assertion "0" failed` consistently happens in `NtUserCreateWindowEx` after the `USER` lock was taken in `NtUserSetWindowPos`. I do not yet understand why the lock is still held at that point (missed release vs unexpected reentrancy vs call ordering / dispatch issue), but it is clearly a locking invariant violation and likely not specific to the Android backend. For debugging purposes, I modified the code to print two backtraces into `logcat` (Android logging subsystem): 1) the backtrace from the last `user_lock` call. 2) the backtrace from the failing `user_check_not_lock` call. Unfortunately, the resulting traces do not clearly indicate where the contract is being violated. <details> <summary>Log</summary> I added symbolization from in-process addresses to function names and source locations. However, these may not exactly match the current state of the upstream Git repository, since I had to apply a few additional local modifications to make the build sufficiently functional and capable of producing logs. ``` ---------------------------- PROCESS STARTED (7705) for package org.winehq.wine ---------------------------- 12:53:44.258 OpenGLRenderer I Initialized EGL, version 1.4 12:53:44.258 OpenGLRenderer D Swap behavior 1 12:53:45.955 WineOut D 0054:err:dnsapi:DllMain No libresolv support, expect problems 12:53:46.227 WineOut D 00a8:err:ntoskrnl:ZwLoadDriver failed to create driver L"\\Registry\\Machine\\System\\CurrentControlSet\\Services\\winebth": c00000e5 12:53:46.230 WineOut D 003c:fixme:service:scmdatabase_autostart_services Auto-start service L"winebth" failed to start: 1359 12:53:46.581 WineOut D 0024:trace:explorer:manage_desktop display guid {4df6ccdc-412d-4953-8076-871c3a2839ad} 12:53:46.596 WineOut D 0024:trace:android:enum_libs found libhardware at 0xa9d6a034 12:53:46.596 WineOut D 0024:trace:android:init_gralloc got module 0xa8155008 ver 0.1 id "gralloc" name "Graphics Memory Allocator Module" author "The Android Open Source Project" 12:53:46.596 WineOut D 0024:trace:explorer:load_graphics_driver display {4df6ccdc-412d-4953-8076-871c3a2839ad} driver L"wineandroid.drv" 12:53:46.598 WineOut D 00d8:trace:android:device_thread starting process 20 12:53:46.599 wine I create desktop view 12:53:46.607 wine I create hwnd fffffffd 12:53:46.622 wine I config_changed: 160 dpi 12:53:46.623 wine I desktop size 1024x696 12:53:46.623 wine I desktop_changed: 1024x696 12:53:46.623 WineOut D 0024:trace:android:process_events CONFIG_CHANGED dpi 160 12:53:46.628 WineOut D 0024:trace:android:process_events DESKTOP_CHANGED 1024x696 12:53:46.673 WineOut D 0024:err:wgl:egldrv_init_pixel_formats Failed to get any configs from eglChooseConfig 12:53:46.795 WineOut D 0024:trace:android:ANDROID_WindowPosChanging hwnd 0x10020, swp_flags 0x14, shaped 0, rects { window (0,0)-(0,0), client (0,0)-(0,0), visible (0,0)-(0,0) } 12:53:46.796 WineOut D 0024:trace:android:ANDROID_WindowPosChanging hwnd 0x10020, swp_flags 0x10, shaped 0, rects { window (0,0)-(0,0), client (0,0)-(0,0), visible (0,0)-(0,0) } 12:53:46.797 WineOut D 0024:trace:android:ANDROID_CreateWindow 0x10020 12:53:46.797 WineOut D 0024:trace:android:create_ioctl_window -> 0xadc330e0 0x10020 opengl=0 12:53:46.806 WineOut D 00d8:trace:android:createWindow_ioctl hwnd 00010020 opengl 0 parent fffffffd 12:53:46.806 wine I create hwnd 00010020 12:53:46.808 WineOut D 0024:trace:android:ANDROID_WindowPosChanging hwnd 0x10028, swp_flags 0x14, shaped 0, rects { window (0,0)-(100,100), client (0,0)-(100,100), visible (0,0)-(100,100) } 12:53:46.809 WineOut D 0024:trace:android:ANDROID_WindowPosChanging hwnd 0x10028, swp_flags 0x10, shaped 0, rects { window (0,0)-(100,100), client (0,0)-(100,100), visible (0,0)-(100,100) } 12:53:46.809 WineOut D 0024:trace:android:ANDROID_CreateWindow 0x10028 12:53:46.810 WineOut D 0024:trace:explorer:desktop_wnd_proc got msg 0080 wp 1 lp 1002a 12:53:46.811 WineOut D 0024:trace:explorer:desktop_wnd_proc got msg 000c wp 0 lp 34ad08 12:53:46.811 WineOut D 0024:trace:explorer:desktop_wnd_proc got msg 0046 wp 0 lp 31f2a4 12:53:46.812 WineOut D 0024:trace:explorer:desktop_wnd_proc got msg 0083 wp 1 lp 31f270 12:53:46.812 WineOut D 0024:trace:android:ANDROID_WindowPosChanging hwnd 0x10020, swp_flags 0x104a, shaped 0, rects { window (0,0)-(1024,696), client (0,0)-(1024,696), visible (0,0)-(1024,696) } 12:53:46.813 WineOut D 0024:trace:android:ANDROID_CreateWindowSurface hwnd 0x10020, layered 0, surface_rect (0,0)-(1024,768), surface 0x21f3b4 12:53:46.825 WineOut D 0024:trace:android:ANDROID_WindowPosChanged win 0x10020 new_rects { window (0,0)-(1024,696), client (0,0)-(1024,696), visible (0,0)-(1024,696) } style 96000000 owner 0x0 after 0x0 flags 8000116a 12:53:46.825 WineOut D 00d8:trace:android:windowPosChanged_ioctl hwnd 00010020 win (0,0)-(1024,696) client (0,0)-(1024,696) visible (0,0)-(1024,696) style 96000000 flags 8000116a after 00000000 owner 00000000 12:53:46.825 wine I pos changed hwnd 00010020 after 00000000 owner 00000000 style 96000000 win Rect(0, 0 -

I would greatly appreciate any hints on where to look next or which areas would be most relevant to investigate.

It's possible, or even likely, that the lock is being held because the thread that entered it crashed while executing the NtUserSetWindowPos syscall, and was unwound to the syscall dispatcher without releasing it. I have no experience with Android/wineandroid development, but that's usually easy to debug by adding a breakpoint (either with a debugger / software one / an ERR trace) in segv_handler.

I did consider that possibility, although I was hoping that if a crash occurred inside NtUserSetWindowPos, Wine would at least emit some indication in the logs. Since Wine installs its own signal/crash handlers, I expected to see at least a diagnostic line if a fault happened and the thread was unwound through the syscall dispatcher.

Well they should be visible with WINEDEBUG=+seh but otherwise it usually silently swallows the exception and returns to the PE side.
