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 the 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 check_return_arch_not_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. # # 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: https://lists.ozlabs.org/pipermail/linuxppc-dev/2019-February/185379.html # - Aneesh's Book3S hash series: https://lwn.net/Articles/655642/ # - Balbir's Book3S radix series: https://patchwork.ozlabs.org/patch/795211/ # # Cc: Christophe Leroy <christophe.leroy@c-s.fr> # Cc: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> # Cc: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Daniel Axtens <dja@axtens.net> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6e87dcba7ecd9446859b5af119ee34e33007b934 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/chleroy_40x_kilauea_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/kilauea_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/chleroy_40x_kilauea_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:886: Warning: invalid register expression Completed OK # rm -rf /kisskb/build/chleroy_40x_kilauea_defconfig_powerpc-gcc5 # Build took: 0:00:21.584518
