            Bug ID: 60232
           Summary: GetCurrentHwProfileA crashes on a NULL argument, and
                    the profile guid is hardcoded
           Product: Wine
           Version: 11.16
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: [e-mail]
          Reporter: [e-mail]
  Target Milestone: ---
      Distribution: ---

GetCurrentHwProfile is still the semi-stub added in 2002. Four separate
problems, all reproduced on an unmodified wine-11.16 build (../configure
--enable-archs=i386,x86_64, fresh prefix, no DLL overrides), compared against
Windows 11 on the same machine using the same binary.

1. GetCurrentHwProfileA(NULL) crashes.

     wine: Unhandled page fault on write access to 0000000000000000
           at address 00006FFFFF1E3F38

   There is no NULL check, so the first write to pInfo->dwDockInfo faults.
   Windows returns FALSE and sets ERROR_INVALID_PARAMETER (0x57).

2. The profile guid is a constant compiled into Wine, so every installation
   reports the same machine identity:

     Wine:      {12340001-1234-1234-1234-123456789012}
     Windows:   {7572da61-84c6-11f0-a00e-806e6f6e6963}

   Applications use this value to identify the machine they are running on.

3. GetCurrentHwProfileW always returns FALSE. On Windows it succeeds and
   returns values matching the A version.

4. dwDockInfo is DOCKINFO_DOCKED (0x2). On the Windows machine it is
   DOCKINFO_UNDOCKED (0x1).

On Windows the profile lives at

  HKLM\System\CurrentControlSet\Control\IDConfigDB\Hardware Profiles\0001
    HwProfileGuid = "{7572da61-84c6-11f0-a00e-806e6f6e6963}"
    FriendlyName  = "Undocked Profile"

with CurrentConfig, CurrentDockInfo\DockingState, AcpiAlias\0001 and a
Hardware Profiles\0000 template alongside it. The guid there is a version 1
UUID whose timestamp is 2025-08-29, matching when Windows was installed on
this machine, which supports MSDN's statement that the system generates it at
install time. Its node field is the fixed value 806e6f6e6963 rather than a MAC
address.

Bug 4468 covers the same stub but was closed as FIXED once Full Tilt Poker
started working again; the commit recorded there (eb48a472) only corrects a
typo in the hardcoded guid string, which had one hex digit too many for five
years. The function itself was never implemented. Bug 4468 Comment #12 on that
bug
already describes the NULL crash and outlines what a real implementation would
need to do.
