Date: Tue, 8 May 2018 17:42:16 -0700 From: Kees Cook <keescook@...omium.org> To: Matthew Wilcox <mawilcox@...rosoft.com> Cc: Kees Cook <keescook@...omium.org>, Rasmus Villemoes <linux@...musvillemoes.dk>, linux-kernel@...r.kernel.org, linux-mm@...ck.org, kernel-hardening@...ts.openwall.com Subject: [RFC][PATCH 00/13] Provide saturating helpers for allocation This is a stab at providing three new helpers for allocation size calculation: struct_size(), array_size(), and array3_size(). These are implemented on top of Rasmus's overflow checking functions, and the last 8 patches are all treewide conversions of open-coded multiplications into the various combinations of the helper functions. -Kees
