Long Li 0196802993 scsi: storvsc: Set correct data length for sending SCSI command without payload
commit 87c4b5e8a6b65189abd9ea5010ab308941f964a4 upstream.

In StorVSC, payload->range.len is used to indicate if this SCSI command
carries payload. This data is allocated as part of the private driver data
by the upper layer and may get passed to lower driver uninitialized.

For example, the SCSI error handling mid layer may send TEST_UNIT_READY or
REQUEST_SENSE while reusing the buffer from a failed command. The private
data section may have stale data from the previous command.

If the SCSI command doesn't carry payload, the driver may use this value as
is for communicating with host, resulting in possible corruption.

Fix this by always initializing this value.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
