CIFSSMBRenameOpenFile() uses SMB_SET_FILE_RENAME_INFORMATION (0x3f2) level which is SMB PASSTHROUGH level (>= 0x03e8). SMB PASSTHROUGH levels are supported only when server announce CAP_INFOLEVEL_PASSTHRU. All usage of CIFSSMBRenameOpenFile() execept the one is already guarded by checks which prevents calling it against servers without support for CAP_INFOLEVEL_PASSTHRU. The remaning usage without guard is in cifs_do_rename() function, so add missing guard here. Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com>
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 reStructuredText 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.
