To quote a later patch in the series: tl;dr: In order to eliminate a large class of common buffer overflow flaws that continue to persist in the kernel, have memcpy() (under CONFIG_FORTIFY_SOURCE) perform bounds checking of the destination struct member when they have a known size. This would have caught all of the memcpy()-related buffer write overflow flaws identified in at least the last three years. As this series introduces various helpers and performs several phases of treewide cleanups, I'm expecting to carry this series in my tree, so I'd love to get some Reviews and Acks. Given the size, I've mostly aimed this series at various mailing lists, otherwise the CC size got really big. :) Specifically, this series is logically split into several steps: Clean up remaining simple compile-time memcpy() warnings: media: omap3isp: Extract struct group for memcpy() region mac80211: Use flex-array for radiotap header bitmap rpmsg: glink: Replace strncpy() with strscpy_pad() Introduce struct_group() and apply it treewide to avoid compile-time memcpy() warnings: stddef: Introduce struct_group() helper macro skbuff: Switch structure bounds to struct_group() bnxt_en: Use struct_group_attr() for memcpy() region staging: rtl8192e: Use struct_group() for memcpy() region staging: rtl8192u: Use struct_group() for memcpy() region staging: rtl8723bs: Avoid field-overflowing memcpy() lib80211: Use struct_group() for memcpy() region net/mlx5e: Avoid field-overflowing memcpy() mwl8k: Use struct_group() for memcpy() region libertas: Use struct_group() for memcpy() region libertas_tf: Use struct_group() for memcpy() region ipw2x00: Use struct_group() for memcpy() region thermal: intel: int340x_thermal: Use struct_group() for memcpy() region iommu/amd: Use struct_group() for memcpy() region cxgb3: Use struct_group() for memcpy() region ip: Use struct_group() for memcpy() regions intersil: Use struct_group() for memcpy() region cxgb4: Use struct_group() for memcpy() region bnx2x: Use struct_group() for memcpy() region drm/amd/pm: Use struct_group() for memcpy() region staging: wlan-ng: Use struct_group() for memcpy() region drm/mga/mga_ioc32: Use struct_group() for memcpy() region net/mlx5e: Use struct_group() for memcpy() region HID: cp2112: Use struct_group() for memcpy() region Prepare fortify for additional hardening: compiler_types.h: Remove __compiletime_object_size() lib/string: Move helper functions out of string.c fortify: Move remaining fortify helpers into fortify-string.h fortify: Explicitly disable Clang support Add compile-time and run-time tests: fortify: Add compile-time FORTIFY_SOURCE tests lib: Introduce CONFIG_TEST_MEMCPY Enable new compile-time memcpy() and memmove() bounds checking: fortify: Detect struct member overflows in memcpy() at compile-time fortify: Detect struct member overflows in memmove() at compile-time Clean up remaining simple compile-time memset() warnings: scsi: ibmvscsi: Avoid multi-field memset() overflow by aiming at srp Introduce memset_after() helper and apply it (and struct_group()) treewide to avoid compile-time memset() warnings: string.h: Introduce memset_after() for wiping trailing members/padding xfrm: Use memset_after() to clear padding mac80211: Use memset_after() to clear tx status net: 802: Use memset_after() to clear struct fields net: dccp: Use memset_after() for TP zeroing net: qede: Use memset_after() for counters ath11k: Use memset_after() for clearing queue descriptors iw_cxgb4: Use memset_after() for cpl_t5_pass_accept_rpl intel_th: msu: Use memset_after() for clearing hw header IB/mthca: Use memset_after() for clearing mpt_entry btrfs: Use memset_after() to clear end of struct drbd: Use struct_group() to zero algs cm4000_cs: Use struct_group() to zero struct cm4000_dev region KVM: x86: Use struct_group() to zero decode cache tracing: Use struct_group() to zero struct trace_iterator dm integrity: Use struct_group() to zero struct journal_sector HID: roccat: Use struct_group() to zero kone_mouse_event ipv6: Use struct_group() to zero rt6_info RDMA/mlx5: Use struct_group() to zero struct mlx5_ib_mr ethtool: stats: Use struct_group() to clear all stats at once netfilter: conntrack: Use struct_group() to zero struct nf_conn powerpc: Split memset() to avoid multi-field overflow Enable new compile-time memset() bounds checking: fortify: Detect struct member overflows in memset() at compile-time Enable Clang support and global array-bounds checking: fortify: Work around Clang inlining bugs Makefile: Enable -Warray-bounds Avoid run-time memcpy() bounds check warnings: netlink: Avoid false-positive memcpy() warning iwlwifi: dbg_ini: Split memcpy() to avoid multi-field write Enable run-time memcpy() bounds checking: fortify: Add run-time WARN for cross-field memcpy() A future series will clean up for and add run-time memset() bounds checking.
