Hi Randy,
Here is some code I did in complete routine.
when user renames c:\temp1\foo1.txt to c:\temp\bar1.txt, FS driver
want to rename d:\temp2\foo2.txt to d:\temp2\bar2.txt at the same time.
I understand other experts said when IO manager open target
c:\temp\bar1.txt
with flag SL_OPEN_TARGET_DIRECTORY, it return success with
FILE_DOES_NOT_EXIST
and prepare to rename. But FS driver follow this prepare to open its own
fully qualified target “\??\d:\temp2\bar2.txt”, I got unsuccessful
with STATUS_OBJECT_NAME_NOT_FOUND.
Should I only open the directory not the fully qualified target name?
Thanks
NTSTATUS CreateComplete(IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp,
IN PVOID Contex)
{
ULONG CreateDisposition;
ULONG IrpStatusInfo;
PIO_STACK_LOCATION currentIrpStack;
PUNICODE_STRING pusRealFileName;
HANDLE hFile;
POPENCONTEX pOpenContex;
OBJECT_ATTRIBUTES objectAttributes;
NTSTATUS status = STATUS_SUCCESS;
pOpenContex = (POPENCONTEX)Contex;
pusRealFileName = pOpenContex->pusRealFileName;
currentIrpStack = IoGetCurrentIrpStackLocation(Irp);
IrpStatusInfo = Irp->IoStatus.Information;
CreateDisposition = currentIrpStack->Parameters.Create.Options >> 24)
& 0xFF;
if (NT_SUCCESS(Irp->IoStatus.Status) && (currentIrpStack->Flags &
SL_OPEN_TARGET_DIRECTORY)) {
RtlZeroMemory(&objectAttributes, sizeof(objectAttributes));
InitializeObjectAttributes(&objectAttributes,
pusRealFileName,
OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,
NULL,
NULL);
status = ZwCreateFile(&hFile,
currentIrpStack->Parameters.Create.SecurityContext>DesiredAccess,
&objectAttributes, // IN POBJECT_ATTRIBUTES ObjectAttributes
&Irp->IoStatus, // OUT PIO_STATUS_BLOCK IoStatusBlock
NULL, // IN PLARGE_INTEGER AllocationSize
currentIrpStack->Parameters.Create.FileAttributes,
currentIrpStack->Parameters.Create.ShareAccess,
CreateDisposition,
currentIrpStack->Parameters.Create.SecurityContext->FullCreateOptions,
NULL, // EaBuffer
0); // EaLength
}
return status;
}
Can you post the code?
