Hi Andrew, This is a refresh of the __alloc_size series you have in -mm currently. This addresses the issues[1] Linus had with attribute location and the redundant use of __malloc. These are meant to replace the following patches: compiler-attributes-add-__alloc_size-for-better-bounds-checking.patch compiler-attributes-add-__alloc_size-for-better-bounds-checking-fix.patch checkpatch-add-__alloc_size-to-known-attribute.patch slab-clean-up-function-declarations.patch slab-add-__alloc_size-attributes-for-better-bounds-checking.patch mm-page_alloc-add-__alloc_size-attributes-for-better-bounds-checking.patch percpu-add-__alloc_size-attributes-for-better-bounds-checking.patch mm-vmalloc-add-__alloc_size-attributes-for-better-bounds-checking.patch rapidio-avoid-bogus-__alloc_size-warning.patch Thanks! -Kees [1] https://lore.kernel.org/mm-commits/CAHk-=wgfbSyW6QYd5rmhSHRoOQ=ZvV+jLn1U8U4nBDgBuaOAjQ@xxxxxxxxxxxxxx/ v3: - move attribute logic around to better handle GCC's weird behavior - merge __malloc into the __alloc_size macro (Linus) - refactor attribute positions (Linus) v2: https://lore.kernel.org/lkml/20210818214021.2476230-1-keescook@xxxxxxxxxxxx v1: https://lore.kernel.org/lkml/20210818050841.2226600-1-keescook@xxxxxxxxxxxx Original cover letter: GCC and Clang both use the "alloc_size" attribute to assist with bounds checking around the use of allocation functions. Add the attribute, adjust the Makefile to silence needless warnings, and add the hints to the allocators where possible. These changes have been in use for a while now in GrapheneOS.
