            Bug ID: 57330
           Summary: NtQueryVolumeInformationFile does not work on Z: drive
                    on default configuration
           Product: Wine
           Version: 9.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: wine-bugs(a)winehq.org
          Reporter: joshudson(a)gmail.com
      Distribution: ---

Calling NtQueryVolumeInformationFile on an open handle that's opened from the
Z: drive returns Invalid Function.

I tried to run the test harness for my .NET File Systems DLL on Wine, and it
didn't get very far. Almost nothing works because it wants the volume serial
number, which on actual Windows is a cheap call.

Source code line of failure:
https://github.com/joshudson/Emet/blob/302fe61d0b8614e2a57930fc75cffa034ba3d...

What's interesting is this code *doesn't want* the volume serial number; it
*wants* any unique volume identifier given a handle where all handles on the
same handle get the same result. I could in theory detect wine here if I had a
good way to implement the problem elsehow on Wine; say by one of the wine
specific IOCTL calls. (The obvious solution is if I get back Invalid Function
here; make the wine-specific call before giving up.)

If you actually run the test battery
https://github.com/joshudson/Emet/blob/302fe61d0b8614e2a57930fc75cffa034ba3d...
it should be a pretty good supplemental test battery for Wine's filesystem
layer.
