[Bug 58043] New: DVDFab won't run on Wine 10.3 because it thinks that there is a debugger running when there isn't
https://bugs.winehq.org/show_bug.cgi?id=58043 Bug ID: 58043 Summary: DVDFab won't run on Wine 10.3 because it thinks that there is a debugger running when there isn't Product: Wine Version: 10.3 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: alexhenrie24(a)gmail.com Distribution: --- Created attachment 78297 --> https://bugs.winehq.org/attachment.cgi?id=78297 Screenshot To reproduce, run `wine dvdfab13_online_13037.exe`. When installation is complete, an error dialog appears that says "A debugger has been found running in your system. Please, unload it from memory and restart your program." This error did not happen before Wine 10.3. `git bisect` says: dc718fd33b23a6104a0fa2e971a358662bf766af is the first bad commit commit dc718fd33b23a6104a0fa2e971a358662bf766af (HEAD) Author: Alexandre Julliard <julliard(a)winehq.org> AuthorDate: Tue Feb 25 13:45:33 2025 +0100 Commit: Alexandre Julliard <julliard(a)winehq.org> CommitDate: Tue Feb 25 23:01:11 2025 +0100 ntdll: Add some missing Zw exports. dlls/ntdll/ntdll.spec | 23 ++++++++++++++++------- 1 file changed, 16 insertions(+), 7 deletions(-) $ sha256sum dvdfab13_online_13037.exe 9260ecbad0ddeeca876ff7adb35d26cffc7fb40399c814ae6fd369d2d7708791 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=58043 --- Comment #1 from Alex Henrie <alexhenrie24(a)gmail.com> --- Commenting out both ZwAllocateReserveObject and ZwCallbackReturn in ntdll.spec avoids the error. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58043 --- Comment #2 from Alex Henrie <alexhenrie24(a)gmail.com> --- Adding a non-existent function that starts with "Zw" to ntdll.spec, for example "@stub ZwFoobar", also triggers the error. That makes me think that DVDFab is looking at all ntdll functions that start with "Zw" and checking them for something. I still don't know what exactly it doesn't like about ZwAllocateReserveObject and ZwCallbackReturn though. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58043 --- Comment #3 from Alex Henrie <alexhenrie24(a)gmail.com> --- Okay, the problem is not with ZwAllocateReserveObject and ZwCallbackReturn specifically: Commenting out any two (or more) Zw functions in ntdll.spec before ZwClose avoids the error. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

With those present with the current Wine git it is missing two things: 1. It starts doing direct syscalls. https://gitlab.winehq.org/wine/wine-staging/-/blob/master/patches/ntdll-Sysc... allows to do that in principle (although proper solution should be different). Yet it hits p. 2. on the way. 2. With default Win10 version in the prefix those syscall numbers are hardcoded in the DRM (matching those on Windows for specified version). So that would need to match in Wine (or, as a hack, mapped in sigsys handler although that can't be done unconditionally, more often DRMs detect actual syscall numbers from syscall thunks or from Nt functions order). With Win version set to Win11 DRM fallbacks to detecting the numbers from actual ntdll and DVDFab starts with the patch from p. 1. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I confirmed that DVDFab starts without error on Wine Staging 10.7 with the Windows version set to 11 in winecfg. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

It's a free download. On Wine 10.3 and later, DCS_updater.exe reports: A debugger has been found running in your system. Please, unload it from memory and restart your program. This happens very early during startup, so it should be easy to find. Changing the Windows version to Windows 11 does not help.

You need Wine Staging. Regular Wine doesn't work yet. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Thank you for letting me know! I assumed that Wine Staging is simply the upcoming point release. Can confirm: Wine Staging, v10.12 in my case, fixes the issue with DCS as well. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
