Miaoqian Lin 5d5f08fd0c xtensa: simdisk: add input size check in proc_write_simdisk 
A malicious user could pass an arbitrarily bad value
to memdup_user_nul(), potentially causing kernel crash.

This follows the same pattern as commit ee76746387
("netdevsim: prevent bad user input in nsim_dev_health_break_write()")

Fixes: b6c7e873da ("xtensa: ISS: add host file-based simulated disk")
Fixes: 16e5c1fc36 ("convert a bunch of open-coded instances of memdup_user_nul()")

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 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.
