Pull sysfs module section fix from Kees Cook: "Fix sysfs module section output overflow. About a month after my kallsyms_show_value() refactoring landed, 0day noticed that there was a path through the kernfs binattr read handlers that did not have PAGE_SIZEd buffers, and the module "sections" read handler made a bad assumption about this, resulting in it stomping on memory when reached through small-sized splice() calls. I've added a set of tests to find these kinds of regressions more quickly in the future as well" Sefltests-acked-by: Shuah Khan <skhan@linuxfoundation.org> * tag 'kallsyms_show_value-fix-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: selftests: splice: Check behavior of full and short splices module: Correctly truncate sysfs sections output
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.
