Merge tag 'kallsyms_show_value-fix-v5.9-rc1' of git://
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 <> * tag 'kallsyms_show_value-fix-v5.9-rc1' of git:// selftests: splice: Check behavior of full and short splices module: Correctly truncate sysfs sections output
