Subject: [PATCH v3 00/15] kasan: HW_TAGS tests support and fixes
Date: Thu, 14 Jan 2021 20:36:16 +0100	[thread overview]
Message-ID: <cover.1610652890.git.andreyknvl@google.com> (raw)

This patchset adds support for running KASAN-KUnit tests with the
hardware tag-based mode and also contains a few fixes.

Changes v2->v3:
- Don't call kmalloc(0) when generating random size.
- Use ARRAY_SIZE() in kmem_cache_bulk_alloc() test.
- Print error message when tests are being ran with kasan.mode=off.
- Move _RET_IP_ to inline wrappers for kasan annotations.

Andrey Konovalov (15):
  kasan: prefix global functions with kasan_
  kasan: clarify HW_TAGS impact on TBI
  kasan: clean up comments in tests
  kasan: add macros to simplify checking test constraints
  kasan: add match-all tag tests
  kasan, arm64: allow using KUnit tests with HW_TAGS mode
  kasan: rename CONFIG_TEST_KASAN_MODULE
  kasan: add compiler barriers to KUNIT_EXPECT_KASAN_FAIL
  kasan: adapt kmalloc_uaf2 test to HW_TAGS mode
  kasan: fix memory corruption in kasan_bitops_tags test
  kasan: move _RET_IP_ to inline wrappers
  kasan: fix bug detection via ksize for HW_TAGS mode
  kasan: add proper page allocator tests
  kasan: add a test for kmem_cache_alloc/free_bulk
  kasan: don't run tests when KASAN is not enabled
