As usual patches available in git
git://github.com/aryabinin/linux.git kasan/arm64v6
Changes since v5:
- Rebase on top of 4.3-rc1
- Fixed EFI boot.
- Updated Doc/features/KASAN.
Changes since v4:
- Generate KASAN_SHADOW_OFFSET using 32 bit arithmetic
- merge patches x86/kasan: switch to generic kasan_populate_zero_shadow()
and mm: introduce generic kasan_populate_zero_shadow() into one.
- remove useless check for start != 0 in clear_pgds()
- Don't generate KASAN_SHADOW_OFFSET in Makefile for x86,
assign it in Makefile.kasan if CONFIG_KASAN_SHADOW_OFFSET was defined.
Changes since v3:
- Generate KASAN_SHADOW_OFFSET in Makefile
- zero_p*_populate() functions now return void
- Switch x86 to generic kasan_populate_zero_shadow() too
- Add license headers
- fix memleak in kasan_populate_zero_shadow:
Following code could leak memory when pgd_populate() is nop:
void *p = early_alloc(PAGE_SIZE, NUMA_NO_NODE);
pgd_populate(&init_mm, pgd, p);
This was replaced by:
pgd_populate(&init_mm, pgd, early_alloc(PAGE_SIZE, NUMA_NO_NODE));
Changes since v2:
- Rebase on top of v4.2-rc3
- Address feedback from Catalin.
- Print memory assignment from Linus
- Add message about KASAN being initialized
Changes since v1:
- Address feedback from Catalin.
- Generalize some kasan init code from arch/x86/mm/kasan_init_64.c
and reuse it for arm64.
- Some bugfixes, including:
add missing arm64/include/asm/kasan.h
add tlb flush after changing ttbr1
- Add code comments.
Andrey Ryabinin (5):
arm64: introduce VA_START macro - the first kernel virtual address.
arm64: move PGD_SIZE definition to pgalloc.h
x86, efi, kasan: #undef memset/memcpy/memmove per arch.
arm64: add KASAN support
Documentation/features/KASAN: arm64 supports KASAN now
Linus Walleij (1):

Config attached. beyond fixing the build bug ... could we also engineer this in a better fashion than spreading random #undefs across various KASAN unrelated headers?

[-Werror=implicit-function-declaration] arch/x86/platform/efi/efi_64.c:139:2: error: implicit declaration of function a??memcpya?? [-Werror=implicit-function-declaration] ./arch/x86/include/asm/desc.h:121:2: error: implicit declaration of function a??memcpya?? [-Werror=implicit-function-declaration] I guess it's about EFI=y but KASAN=n. Config attached. beyond fixing the build bug ... could we also engineer this in a better fashion than spreading random #undefs across various KASAN unrelated headers?

Config attached. It's actually, it's about KMEMCHECK=y and KASAN=n, because declaration of memcpy() is hidden under ifndef. arch/x86/include/asm/string_64.h: #ifndef CONFIG_KMEMCHECK #if (__GNUC__ == 4 && __GNUC_MINOR__ >= 3) || __GNUC__ > 4 extern void *memcpy(void *to, const void *from, size_t len); #else #define memcpy(dst, src, len) \ ....... #endif #else /* * kmemcheck becomes very happy if we use the REP instructions unconditionally, * because it means that we know both memory operands in advance. */ #define memcpy(dst, src, len) __inline_memcpy((dst), (src), (len)) #endif So it also broke build with GCCs 4.0 - 4.3. And it also breaks clang build, because AFAIK clang defines GNUC, GNUC_MINOR as 4.2. > > beyond fixing the build bug ... could we also engineer this in a better fashion > than spreading random #undefs across various KASAN unrelated headers? I think we can add something like -DNOT_KERNEL (anyone has a better name ?) to the CFLAGS for everything that is not linked with the kernel binary (efistub, arch/x86/boot) So, if NOT_KERNEL is defined we will not #define memcpy(), so we won't need these undefs. > Thanks, > > Ingo -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.

* [PATCH v6 4/6] arm64: add KASAN support 2015-09-17 9:38 ` Andrey Ryabinin (?) @ 2015-09-17 9:38 ` Andrey Ryabinin -1 siblings, 0 replies; 76+ messages in thread From: Andrey Ryabinin @ 2015-09-17 9:38 UTC (permalink / raw) To: linux-arm-kernel This patch adds arch specific code for kernel address sanitizer (see Documentation/kasan.txt). 1/8 of kernel addresses reserved for shadow memory. There was no big enough hole for this, so virtual addresses for shadow were stolen from vmalloc area. At early boot stage the whole shadow region populated with just one physical page (kasan_zero_page). Later, this page reused as readonly zero shadow for some memory that KASan currently don't track (vmalloc). After mapping the physical memory, pages for shadow memory are allocated and mapped. Functions like memset/memmove/memcpy do a lot of memory accesses. If bad pointer passed to one of these function it is important to catch this. Compiler's instrumentation cannot do this since these functions are written in assembly. KASan replaces memory functions with manually instrumented variants. Original functions declared as weak symbols so strong definitions in mm/kasan/kasan.c could replace them. Original functions have aliases with '__' prefix in name, so we could call non-instrumented variant if needed. Some files built without kasan instrumentation (e.g. mm/slub.c). Original mem* function replaced (via #define) with prefixed variants to disable memory access checks for such files.

* [PATCH v6 4/6] arm64: add KASAN support @ 2015-09-17 9:38 ` Andrey Ryabinin 0 siblings, 0 replies; 76+ messages in thread From: Andrey Ryabinin @ 2015-09-17 9:38 UTC (permalink / raw) To: Will Deacon, Catalin Marinas, linux-arm-kernel Cc: Andrey Ryabinin, Linus Walleij, Alexander Potapenko, Dmitry Vyukov, Arnd Bergmann, linux-kernel, David Keitel, linux-mm, Alexey Klimov, Yury, Andrey Konovalov This patch adds arch specific code for kernel address sanitizer (see Documentation/kasan.txt). 1/8 of kernel addresses reserved for shadow memory. There was no big enough hole for this, so virtual addresses for shadow were stolen from vmalloc area. At early boot stage the whole shadow region populated with just one physical page (kasan_zero_page). Later, this page reused as readonly zero shadow for some memory that KASan currently don't track (vmalloc). After mapping the physical memory, pages for shadow memory are allocated and mapped. Functions like memset/memmove/memcpy do a lot of memory accesses. If bad pointer passed to one of these function it is important to catch this. Compiler's instrumentation cannot do this since these functions are written in assembly. KASan replaces memory functions with manually instrumented variants. Original functions declared as weak symbols so strong definitions in mm/kasan/kasan.c could replace them. Original functions have aliases with '__' prefix in name, so we could call non-instrumented variant if needed. Some files built without kasan instrumentation (e.g. mm/slub.c). Original mem* function replaced (via #define) with prefixed variants to disable memory access checks for such files.

* [PATCH v6 4/6] arm64: add KASAN support @ 2015-09-17 9:38 ` Andrey Ryabinin 0 siblings, 0 replies; 76+ messages in thread From: Andrey Ryabinin @ 2015-09-17 9:38 UTC (permalink / raw) To: Will Deacon, Catalin Marinas, linux-arm-kernel Cc: Andrey Ryabinin, Linus Walleij, Alexander Potapenko, Dmitry Vyukov, Arnd Bergmann, linux-kernel, David Keitel, linux-mm, Alexey Klimov, Yury, Andrey Konovalov This patch adds arch specific code for kernel address sanitizer (see Documentation/kasan.txt). 1/8 of kernel addresses reserved for shadow memory. There was no big enough hole for this, so virtual addresses for shadow were stolen from vmalloc area. At early boot stage the whole shadow region populated with just one physical page (kasan_zero_page). Later, this page reused as readonly zero shadow for some memory that KASan currently don't track (vmalloc). After mapping the physical memory, pages for shadow memory are allocated and mapped. Functions like memset/memmove/memcpy do a lot of memory accesses. If bad pointer passed to one of these function it is important to catch this. Compiler's instrumentation cannot do this since these functions are written in assembly. KASan replaces memory functions with manually instrumented variants. Original functions declared as weak symbols so strong definitions in mm/kasan/kasan.c could replace them. Original functions have aliases with '__' prefix in name, so we could call non-instrumented variant if needed. Some files built without kasan instrumentation (e.g. mm/slub.c). Original mem* function replaced (via #define) with prefixed variants to disable memory access checks for such files.

You'd better wait for v7, because kasan patches will need some adjustment. Since stub is isolated, we need to handle memcpy vs __memcpy stuff the same way as we do in x86.

I thought the EFI stub isolation patches create a copy of mem*() functions in the stub, but they are just create aliases with __efistub_ prefix. We only need to create some more aliases for KASAN. The following patch on top of the EFI stub isolation series works for me.

It's just not a problem so far. The amount of not instrumented code is fairly small (some low-level x86 code, kasan internals and slub allocator). The purpose of these defines is to not spread kasan-specific details across unrelated code. E.g. there are a lot of memcpy()/memset() calls in slub that used to access object's redzone or freed objects.

It's just not a problem so far. The amount of not instrumented code is fairly small (some low-level x86 code, kasan internals and slub allocator). The purpose of these defines is to not spread kasan-specific details across unrelated code. E.g. there are a lot of memcpy()/memset() calls in slub that used to access object's redzone or freed objects. So it simpler to redefine memset, rather then somehow mangle that code. >> So with CONFIG_KASAN=y the EFI stub uses __memcpy, thus we need to >> create the __efistub___memcpy alias. > > Ok, that makes sense to me. > > Thanks, > Mark. ^ permalink raw reply [flat|nested] 76+ messages in thread
