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):
ARM64: kasan: print memory assignment
