Hi, I am trying to write a filter driver that can redirect open requests, I’ve read many posts about that but I always get the blue screen of death whenever I redirect an open request so please can any one reffer me to a good filter source or copy/paste the code of MJ_CREATE dispatch routine that do that .

Best Regards

if (pFileObject->FileName.MaximumLength >= length of
new path)
{
copy the new path into pFileObject->FileName
}
else
{
ExFreePool(pFileObject->FileName.Buffer)
pFileObject->FileName.Buffer =
ExAllocatePoolWithTag(new buffer big enough to hold
new path);
Fixup Length and MaximumLength params
}

You probably want to set RelatedFileObject to NULL if
you are specifying the full path

Irp->IoStatus.Information = IO_REPARSE;
Irp->IoStatus.Status = STATUS_REPARSE;

IoCompleteRequest(Irp, IO_NO_INCREMENT);

return STATUS_REPARSE
