Merge tag 'overflow-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull overflow updates from Kees Cook:
"These changes come in roughly two halves: support of Gustavo A. R.
Silva's struct_size() work via additional helpers for catching
overflow allocation size calculations, and conversions of selftests to
KUnit (which includes some tweaks for UML + Clang):
- Convert overflow selftest to KUnit
- Convert stackinit selftest to KUnit
- Implement size_t saturating arithmetic helpers
- Allow struct_size() to be used in initializers"
* tag 'overflow-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
lib: stackinit: Convert to KUnit
um: Allow builds with Clang
lib: overflow: Convert to Kunit
overflow: Provide constant expression struct_size
overflow: Implement size_t saturating arithmetic helpers
test_overflow: Regularize test reporting output
