To improve security it may be helpful to have additional ways to restrict the ability to override the default dialects (SMB2.1, SMB3 and SMB3.02) on mount with old dialects (CIFS/SMB1 and SMB2) since vers=1.0 (CIFS/SMB1) and vers=2.0 are weaker and less secure. Add a module parameter "disable_legacy_dialects" (/sys/module/cifs/parameters/disable_legacy_dialects) which can be set to 1 (or equivalently Y) to forbid use of vers=1.0 or vers=2.0 on mount. Also cleans up a few build warnings about globals for various module parms. Signed-off-by: Steve French <smfrench@gmail.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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
