The quilt patch titled Subject: kunit: kasan_test: disable fortify string checker on kmalloc_oob_memset has been removed from the -mm tree. Its filename was kunit-kasan_test-disable-fortify-string-checker-on-kmalloc_oob_memset-v2.patch This patch was dropped because it was folded into kunit-kasan_test-disable-fortify-string-checker-on-kmalloc_oob_memset.patch ------------------------------------------------------ From: Nico Pache <npache@xxxxxxxxxx> Subject: kunit: kasan_test: disable fortify string checker on kmalloc_oob_memset Date: Thu, 14 Dec 2023 09:44:23 -0700 address review comments from Andrey Link: https://lkml.kernel.org/r/20231214164423.6202-1-npache@xxxxxxxxxx Signed-off-by: Nico Pache <npache@xxxxxxxxxx> Cc: Alexander Potapenko <glider@xxxxxxxxxx> Cc: Andrey Konovalov <andreyknvl@xxxxxxxxx> Cc: Andrey Ryabinin <ryabinin.a.a@xxxxxxxxx> Cc: Dmitry Vyukov <dvyukov@xxxxxxxxxx> Cc: Vincenzo Frascino <vincenzo.frascino@xxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/kasan/kasan_test.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) --- a/mm/kasan/kasan_test.c~kunit-kasan_test-disable-fortify-string-checker-on-kmalloc_oob_memset-v2 +++ a/mm/kasan/kasan_test.c @@ -493,7 +493,7 @@ static void kmalloc_oob_memset_2(struct { char *ptr; size_t size = 128 - KASAN_GRANULE_SIZE; - size_t size2 = 2; + size_t memset_size = 2; KASAN_TEST_NEEDS_CHECKED_MEMINTRINSICS(test); @@ -502,8 +502,8 @@ static void kmalloc_oob_memset_2(struct OPTIMIZER_HIDE_VAR(ptr); OPTIMIZER_HIDE_VAR(size); - OPTIMIZER_HIDE_VAR(size2); - KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 1, 0, size2)); + OPTIMIZER_HIDE_VAR(memset_size); + KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 1, 0, memset_size)); kfree(ptr); } @@ -511,7 +511,7 @@ static void kmalloc_oob_memset_4(struct { char *ptr; size_t size = 128 - KASAN_GRANULE_SIZE; - size_t size2 = 4; + size_t memset_size = 4; KASAN_TEST_NEEDS_CHECKED_MEMINTRINSICS(test); @@ -520,8 +520,8 @@ static void kmalloc_oob_memset_4(struct OPTIMIZER_HIDE_VAR(ptr); OPTIMIZER_HIDE_VAR(size); - OPTIMIZER_HIDE_VAR(size2); - KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 3, 0, size2)); + OPTIMIZER_HIDE_VAR(memset_size); + KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 3, 0, memset_size)); kfree(ptr); } @@ -529,7 +529,7 @@ static void kmalloc_oob_memset_8(struct { char *ptr; size_t size = 128 - KASAN_GRANULE_SIZE; - size_t size2 = 8; + size_t memset_size = 8; KASAN_TEST_NEEDS_CHECKED_MEMINTRINSICS(test); @@ -538,8 +538,8 @@ static void kmalloc_oob_memset_8(struct OPTIMIZER_HIDE_VAR(ptr); OPTIMIZER_HIDE_VAR(size); - OPTIMIZER_HIDE_VAR(size2); - KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 7, 0, size2)); + OPTIMIZER_HIDE_VAR(memset_size); + KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 7, 0, memset_size)); kfree(ptr); } @@ -547,7 +547,7 @@ static void kmalloc_oob_memset_16(struct { char *ptr; size_t size = 128 - KASAN_GRANULE_SIZE; - size_t size2 = 16; + size_t memset_size = 16; KASAN_TEST_NEEDS_CHECKED_MEMINTRINSICS(test); @@ -556,8 +556,8 @@ static void kmalloc_oob_memset_16(struct OPTIMIZER_HIDE_VAR(ptr); OPTIMIZER_HIDE_VAR(size); - OPTIMIZER_HIDE_VAR(size2); - KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 15, 0, size2)); + OPTIMIZER_HIDE_VAR(memset_size); + KUNIT_EXPECT_KASAN_FAIL(test, memset(ptr + size - 15, 0, memset_size)); kfree(ptr); } _ Patches currently in -mm which might be from npache@xxxxxxxxxx are kunit-kasan_test-disable-fortify-string-checker-on-kmalloc_oob_memset.patch
