Summary: Invalid PIO_STACK_LOCATION->FileObject passed into
IRP_MJ_DEVICE_CONTROL dispatch routine
Product: Wine
Version: 1.1.29
Platform: PC
URL: http://rh-software.com/
OS/Version: Linux
Status: UNCONFIRMED
Severity: major
Priority: P2
Component: ntoskrnl
AssignedTo: wine-bugs at winehq.org
ReportedBy: ray at pobox.co.uk
When the SIVDRIVER IRP_MJ_DEVICE_CONTROL dispatch routine is called the
PIO_STACK_LOCATION->FileObject in incalid, in fact it's set of 0x66666666.
This caused the v4.00 SIVDRIVER to crash as it expects to setup
PFILE_OBJECT->FsContext in file create callback and use it while processing
IRP_MJ_DEVICE_CONTROL. For 4.01 I managed to stop the crashes by adding code
to check for 0x66666666. This really needs to be fixed though.
