If you do 'wineserver -k' and try to start anything with Wine nothing will happen until wineboot times out... As quickfix, start regedit (wait until wineboot timeout) and set service start type key for "WinMgmt" to manual start, e.g. "2" -> "3". Also a kernel driver (service) that is installed with WMI "smbios" fails to load but this currently harmless. If we look now in "c:\\windows\\system32\\WBEM" we see the whole stuff installed. The logs in "logs" subdirs are not revealing much so we have to increase the log level: --- snip --- [HKEY_LOCAL_MACHINE\Software\Microsoft\WBEM\CIMOM] "Logging"="1" "Logging Directory"="C:\\windows\\system32\\WBEM\\Logs" --- snip --- LogLevel is 0 to turn off logging, a 1 to turn on logging, and a 2 for verbose logging.

The process retrieves token information and checks if process token groups contain "SECURITY_INTERACTIVE_RID" (-> normal process) or "SECURITY_SERVICE_RID" (service process). I think it's actually services.exe that adds the SECURITY_SERVICE_RID sid to the newly created service process (token groups). This requires some infrastructure, including wineserver. I already quick-hacked a path to verify this and it works as expected, letting the service successfully start ;-) Regards -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email 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.

[Bug 24963] New: Okad2: Unhandled page fault at address 0x00007f8a during startup
by wine-bugs＠winehq.org Nov. 26, 2025

Nov. 26, 2025

http://bugs.winehq.org/show_bug.cgi?id=24963 Summary: Okad2: Unhandled page fault at address 0x00007f8a during startup Product: Wine Version: unspecified Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user32 AssignedTo: wine-bugs(a)winehq.org ReportedBy: pandolfo(a)gis.net Created an attachment (id=31617) --> (http://bugs.winehq.org/attachment.cgi?id=31617) a description of the page fault plus an annotated backtrace During program startup, Okad2-xx-pd (xx = version) generates an unhandled page fault when loading an icon. The page fault is caused by CreateFileW as it processes the name of the file from the parameter list. The name pointer is 0x00007f8a, which is an address in an unmapped page. This value is also an index into Windows resources, selecting the hourglass icon. What has happened is that the application was attempting to load the hourglass icon and passed in BOTH the Windows resource index and a flag indicating LOADFROMFILE. Wine attempted to load-from-file and looked for the file name through the "name" parameter (0x00007f8a) generating the page fault. Native Windows appears to give the value of the "name" pointer precedence and determines that the "name" parameter is actually a resource number; hence it does not page fault and runs Okad2 normally. Wine *DOES* check the "name" parameter to see if it is a resource index, but several subroutine calls later it forgets this fact and branches based on the LOADFROMFILE bit. The backtrace has been annotated to provide both a description and source lines involved in the decision. This behavior was found in the latest version of Wine for Debian (.1.42) and in a MacOS X version. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email 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.

This is different from the usual broken apps a la "I failed at porting my 32-bit app to 64-bit" (pointer truncation). In this case, pointers from certain allocations are broken into multiple parts and used as indices into multi-level lookup tables. Pitfall: there is a 44-bit user-mode VA limitation (8TB) for 64-bit Windows which was lifted starting with Windows 8.1+. Wine doesn't respect the 44-bit pre-Windows 8.1 virtual address space limits, allowing process heaps to be placed in 0000'7Fxx'0000'0000 range (128 TB) which causes out-of-bounds access to lookup tables when indices overflow (derived from pointer bits). The exception occurs in entry point, causing 'msxml6.dll' to be unloaded. One workaround is to move Wine's top-down allocations/heaps into 8 TB VA range (Wine preloader) and impose same user-mode address space bits limits as with all 64-bit Windows versions < 8.1 to stay "compatible". I've tested it and it works for native here. Not sure if it's worth to change though. I don't know if a separate 64-bit MSXML6 re-distributable package exists that has been fixed wrt Windows 8.1+ address space limits. MSXML6 is part of Windows OS for newer versions and automatically kept up-to-date. $ sha1sum msxml6_x64.msi 1eb84eeae7729ea5db7fe79779f4e216114261ba msxml6_x64.msi $ du -sh msxml6_x64.msi 2.6M msxml6_x64.msi $ wine --version wine-4.0-276-g84459ba94b Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 15039] New: MSVC 6: Menu popdowns too narrow for arrows
by wine-bugs＠winehq.org Nov. 22, 2025

Nov. 22, 2025

http://bugs.winehq.org/show_bug.cgi?id=15039 Summary: MSVC 6: Menu popdowns too narrow for arrows Product: Wine Version: 1.1.1 Platform: PC-x86-64 OS/Version: Linux Status: NEW Severity: minor Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: claus.fischer(a)clausfischer.com CC: claus.fischer(a)clausfischer.com Microsoft Visual C++ 6 is working to a large extent. When opening a menu of the developer studio, the menu items with arrows (that open submenus) are not displayed correctly. The triangular arrows on the right end will stick out of the menu popdown area. I'm not sure if they just stick out to the end of the "shadow" (3d effect) around the popdown, or sometimes more. They should be fully contained in the popdown area. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email 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.

[Bug 54979] New: Futexes which protect memory allocation congest, causing 100x performance degradation
by WineHQ Bugzilla Nov. 21, 2025

Nov. 21, 2025

https://bugs.winehq.org/show_bug.cgi?id=54979 Bug ID: 54979 Summary: Futexes which protect memory allocation congest, causing 100x performance degradation Product: Wine Version: 8.0.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: nagle(a)animats.com Distribution: --- Created attachment 74518 --> https://bugs.winehq.org/attachment.cgi?id=74518 Debugger output with multiple threads stuck in spinlocks. SUMMARY Under the wrong circumstances, a program doing many memory allocations from multiple threads can experience more than 100x performance degradation. I'm seeing this in my own Rust program, which has 16 sometimes-compute-bound threads on a 12 CPU machine. This works fine on Microsoft Windows and when compiled for Linux. Under Wine, it can be over 100x slower. Multiple threads are banging on a spinlock at _InterlockedCompareExchange [Z:\usr\src\packages\BUILD\include\winnt.h:6630] in ntdll spin_lock [Z:\usr\src\packages\BUILD\dlls\ntdll\sync.c:937] in ntdll This is the spin lock around the queue for pausing threads. DISCUSSION This looks like futex congestion. That's a known kind of problem, but doesn't seem to have been seen in Wine before. It may be that some programs just run really slow under Wine, and nobody knows why. The code in NTDLL is clearly intended to handle the fast case without doing an OS-level lock. Under light load, that's O(1). But under heavy load, with multiple threads pounding on spinlocks, each spinlock waits longer, and there are multiple threads, so it becomes O(N^2). Which means huge slowdowns. See discussion at https://forum.winehq.org/viewtopic.php?t=37688 which has snippets of the code that's causing the problem. I can copy all that info over here if necessary. Let me know. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
