[FIXED IN SVN] VirtualBox fails to start on Windows 10 14286

Hi guys,

it's that time of the year again – the sizeof(IMAGE_LOAD_CONFIG_DIRECTORY64) has changed.

C:\Program Files\Oracle\VirtualBox>VBoxSDL.exe
: RTLdrOpenWithReader failed: Unknown Status -626 (0xfffffd8e) (Image='\SystemRoot\System32\ntdll.dll').

(Where -626 is VERR_LDRPE_LOAD_CONFIG_SIZE, for the external readers.)

Like in #13665 before, it is related to more "Control Flow Guard" changes ( The latest Visual Studio 2015 tools apparently support it already:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\>dumpbin.exe /LOADCONFIG C:\Windows\System32\ntdll.dll

    0000000000000000 Guard CF long jump target table
                   0 Guard CF long jump target count

I failed to find any public headers or symbols with the updated structure yet, so this might be open for a while.

But if there is some consistency applied to naming the new fields there, the dumpbin output above hints towards this addition to what the latest Windows SDK has:

    ULONGLONG  GuardCFAddressTakenIatEntryTable; // VA
    ULONGLONG  GuardCFAddressTakenIatEntryCount;
    ULONGLONG  GuardCFLongJumpTargetTable;       // VA
    ULONGLONG  GuardCFLongJumpTargetCount;

VirtualBox Testbuild
Windows 10 Enterprise Insider Preview x64 rs1_release.14286 (and newer)

Thanks and sorry for the trouble!

A minor correction. rs1_release.14291 has hit the public Insider Fast ring and public symbols for WinTypes.pdb are now available on the MS Symbol Server. The fields are actually named without the "CF" part:

    ULONGLONG  GuardAddressTakenIatEntryTable; // VA
    ULONGLONG  GuardAddressTakenIatEntryCount;
    ULONGLONG  GuardLongJumpTargetTable;       // VA
    ULONGLONG  GuardLongJumpTargetCount;

Summary: VirtualBox fails to start on Windows 10 14286[FIXED IN SVN] VirtualBox fails to start on Windows 10 14286

Thanks for the report! I've updated our structures and PE parser code to handle them.

Here is a test build:

comment:3 by Jiri Hruska, 8 years ago

Cool, thank you!

Verified working on:

  • VirtualBox test build 5.0.17 r106344
  • Windows 10 Enterprise Insider Preview x64 rs1_release.14312

Ticket can be closed as fixed.

comment:4 by Jacob Klein, 8 years ago

Could you please also port the fix to a VirtualBox 4.3.37 Test Build? I cannot upgrade to 5.x yet, but still want to help test the fix on Windows 10 Build 14295 (released to Fast and Slow rings)!

Thanks, Jacob Klein

The latest 4.3 Windows test build has the fix as well. And the 5.0 build is now also properly linked from the test builds page as well.

comment:6 by Jacob Klein, 8 years ago

I confirm that "Oracle VirtualBox v4.3.37 Test Build 106347" does indeed start correctly on Windows 10 Build 14295. Thanks bird and frank!!

Resolution: fixed
Status: newclosed

Fix is part of VBox 5.0.18.

comment:8 by Stanzilla, 8 years ago

Is this the same bug? Started with build 14328 of Win10.

comment:9 by Jessica Hamilton, 8 years ago

I've just upgraded to build 14328 (released today), and this problem is back with 5.0.18. Previous test build 5.0.17 that I was on doesn't work either.

C:\Program Files\Oracle\VirtualBox>vboxsdl
: RTLdrOpenWithReader failed: Unknown Status -626 (0xfffffd8e) (Image='\SystemRoot\System32\ntdll.dll').

C:\Program Files\Oracle\VirtualBox>vboxmanage --version

comment:10 by Jessica Hamilton, 8 years ago

This issue is still present with 5.0.19r106806, fwiw, but probably a bit too early to expect a fixed build...

comment:11 by Jiri Hruska, 8 years ago

Resolution: fixed
Status: closedreopened

Lol, that did not last long, did it...

Indeed, there is another new pointer-sized value at the end of the structure for ASLR improvements in the latest builds.

Edit: details moved to the new #15337, sorry for the necromancy!

Reopening to not have a thousand tickets about the same thing - sorry if that's not what you guys prefer (the previous fix already in a release etc.).
