Namjae Jeon 3003daa76b smb3: add indatalen that can be a non-zero value to calculation of credit charge in smb2 ioctl
commit ebf57440ec59a36e1fc5fe91e31d66ae0d1662d0 upstream.

Some of tests in xfstests failed with cifsd kernel server since commit
e80ddeb2f70e. cifsd kernel server validates credit charge from client
by calculating it base on max((InputCount + OutputCount) and
(MaxInputResponse + MaxOutputResponse)) according to specification.

MS-SMB2 specification describe credit charge calculation of smb2 ioctl :

If Connection.SupportsMultiCredit is TRUE, the server MUST validate
CreditCharge based on the maximum of (InputCount + OutputCount) and
(MaxInputResponse + MaxOutputResponse), as specified in section 3.3.5.2.5.
If the validation fails, it MUST fail the IOCTL request with
STATUS_INVALID_PARAMETER.

This patch add indatalen that can be a non-zero value to calculation of
credit charge in SMB2_ioctl_init().

Fixes: e80ddeb2f70e ("smb3: fix incorrect number of credits when ioctl
MaxOutputResponse > 64K")

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.
