Namjae Jeon a9106b178a ksmbd: the buffer of smb2 query dir response has at least 1 byte
commit ce61b605a0 upstream.

When STATUS_NO_MORE_FILES status is set to smb2 query dir response,
->StructureSize is set to 9, which mean buffer has 1 byte.
This issue occurs because ->Buffer[1] in smb2_query_directory_rsp to
flex-array.

Fixes: eb3e28c1e8 ("smb3: Replace smb2pdu 1-element arrays with flex-arrays")

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.
