From: Andrey Konovalov <andreyknvl@xxxxxxxxx> KASAN tests do out-of-bounds and use-after-free accesses. Running the tests works fine for the GENERIC mode, as it uses qurantine and redzones. But the HW_TAGS mode uses neither, and running the tests might crash the kernel. Rework the tests to avoid corrupting kernel memory. Andrey Konovalov (8): kasan: test: rework kmalloc_oob_right kasan: test: avoid writing invalid memory kasan: test: avoid corrupting memory via memset kasan: test: disable kmalloc_memmove_invalid_size for HW_TAGS kasan: test: only do kmalloc_uaf_memset for generic mode kasan: test: clean up ksize_uaf kasan: test: avoid corrupting memory in copy_user_test kasan: test: avoid corrupting memory in kasan_rcu_uaf lib/test_kasan.c | 74 ++++++++++++++++++++++++++++------------- lib/test_kasan_module.c | 20 +++++------ 2 files changed, 60 insertions(+), 34 deletions(-) -- 2.25.1
