Only outline instrumentation is supported. # # The KASAN shadow area is mapped into vmemmap space: # 0x8000 0400 0000 0000 to 0x8000 0600 0000 0000. # To do this we require that vmemmap be disabled. (This is the default # in the kernel config that QorIQ provides for the machine in their # SDK anyway - they use flat memory.) # # Only the kernel linear mapping (0xc000...) is checked. The vmalloc and # ioremap areas (also in 0x800...) are all mapped to a zero page. As # with the Book3S hash series, this requires overriding the memory <-> # shadow mapping. # # Also, as with both previous 64-bit series, early instrumentation is not # supported. It would allow us to drop the kasan_arch_is_ready() # hook in the KASAN core, but it's tricky to get it set up early enough: # we need it setup before the first call to instrumented code like printk(). # Perhaps in the future. # # Only KASAN_MINIMAL works. # # Lightly tested on e6500. KVM, kexec and xmon have not been tested. # # The test_kasan module fires warnings as expected, except for the # following tests: # # - Expected/by design: # kasan test: memcg_accounted_kmem_cache allocate memcg accounted object # # - Due to only supporting KASAN_MINIMAL: # kasan test: kasan_stack_oob out-of-bounds on stack # kasan test: kasan_global_oob out-of-bounds global variable # kasan test: kasan_alloca_oob_left out-of-bounds to left on alloca # kasan test: kasan_alloca_oob_right out-of-bounds to right on alloca # kasan test: use_after_scope_test use-after-scope on int # kasan test: use_after_scope_test use-after-scope on array # # Thanks to those who have done the heavy lifting over the past several years: # - Christophe's 32 bit series:
