[Bug 9714] New: MapViewOfFile with write permissions should not succeed on a read-only file mapping

http://bugs.winehq.org/show_bug.cgi?id=9714

Summary: MapViewOfFile with write permissions should not succeed
                    on a read-only file mapping
           Product: Wine
           Version: 0.9.38.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I had duplicated some code in one of my programs and accidentally forgot to
change the "desired access" for the MapViewOfFile call, despite having changed
this in the OpenFileMapping call.

The code below *incorrectly* succeeds on WINE but fails on Windows XP.

=== EXAMPLE ===

HANDLE h;
void* m;

h = OpenFileMapping(FILE_MAP_READ, FALSE, "Global\Foo");
m = MapViewOfFile(h, FILE_MAP_WRITE, 0, 0, 0);

=== END EXAMPLE ===

Basically I was opening the mapped file READ-ONLY, but was then trying to
create a writable mapping to it.
