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
