Cause
The file object passed to IoCancelFileOpen is invalid. It should have reference of one. The driver that called IoCancelFileOpen is at fault.
IoCancelFileOpen function
The IoCancelFileOpen routine can be used by a file system filter driver to close a file that has been opened by a file system driver in the filter driver's device stack.
If a file system filter driver determines that a file-open or file-create request must fail after the lower-level drivers have already completed the request with STATUS_SUCCESS, it can use IoCancelFileOpen to close the file opened by the lower-level drivers.
Although STATUS_REPARSE is a success NTSTATUS value, it is not necessary to call IoCancelFileOpen for a create operation that was completed with STATUS_REPARSE, because this status value indicates that the file was not successfully opened.
A successful call to IoCancelFileOpen has the following effect: To minifilters and legacy filters that are above the caller in the file system stack, the create request appears to have failed. To those that are below the caller, the file appears to have been opened (or created) and then closed.
Note that IoCancelFileOpen does not undo any modifications to the file. For example, IoCancelFileOpen does not delete a newly created file or restore a file that was overwritten or superseded to its previous state.
