Merge tag 'kallsyms_show_value-fix-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
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"
