commitba5d4c1596upstream. In cifs_open_file(), @buf must hold a pointer to a cifs_open_info_data structure which is passed by cifs_nt_open(), so assigning @buf directly to @fi was obviously wrong. Fix this by passing a valid FILE_ALL_INFO structure to SMBLegacyOpen() and CIFS_open(), and then copy the set structure to the corresponding cifs_open_info_data::fi field with move_cifs_info_to_smb2() helper.

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.
