Pull FORTIFY_SOURCE updates from Kees Cook: "This series consists of two halves: - strict compile-time buffer size checking under FORTIFY_SOURCE for the memcpy()-family of functions (for extensive details and rationale, see the first commit) - enabling FORTIFY_SOURCE for Clang, which has had many overlapping bugs that we've finally worked past" * tag 'memcpy-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: fortify: Add Clang support fortify: Make sure strlen() may still be used as a constant expression fortify: Use __diagnose_as() for better diagnostic coverage fortify: Make pointer arguments const Compiler Attributes: Add __diagnose_as for Clang Compiler Attributes: Add __overloadable for Clang Compiler Attributes: Add __pass_object_size for Clang fortify: Replace open-coded __gnu_inline attribute fortify: Update compile-time tests for Clang 14 fortify: Detect struct member overflows in memset() at compile-time fortify: Detect struct member overflows in memmove() at compile-time fortify: Detect struct member overflows in memcpy() at compile-time
