This fixes redzoning vs the freelist pointer (both for middle-position and very small caches). Both are "theoretical" fixes, in that I see no evidence of such small-sized caches actually be used in the kernel, but that's no reason to let the bugs continue to exist. :) Thanks! -Kees Kees Cook (3): mm/slub: Clarify verification reporting mm/slub: Fix redzoning for small allocations mm/slub: Actually fix freelist pointer vs redzoning Documentation/vm/slub.rst | 10 +++++----- mm/slub.c | 36 +++++++++++++++--------------------- 2 files changed, 20 insertions(+), 26 deletions(-) -- 2.25.1
