For git users patches are available in git:
git://github.com/aryabinin/linux.git kasan/arm64v4
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.
