If some parts of the # page table still have entries to the zero page shadow memory, the # entries are wrongly marked RW. # # With CONFIG_KASAN_VMALLOC, almost the entire kernel address space # is managed by KASAN. To make it simple, just create KASAN page tables # for the entire kernel space at kasan_init(). That doesn't use much # more space, and that's anyway already done for hash platforms. # # Fixes: 3d4247fcc938 ("powerpc/32: Add support of KASAN_VMALLOC") # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/ef5248fc1f496c6b0dfdb59380f24968f25f75c5.1583513368.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 af3d0a68698c7e5df8b72267086b23422a3954bb # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+STRICT_RWX_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_RELOCATABLE=n # Added to kconfig CONFIG_STRICT_KERNEL_RWX=y # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+STRICT_RWX_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+STRICT_RWX_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:3944:warning: override: reassigning to symbol RELOCATABLE .config:3945:warning: override: reassigning to symbol STRICT_KERNEL_RWX # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powernv_defconfig+STRICT_RWX_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: vmlinux.o(.text+0x2fc8): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel() The function start_here_common() references the function __init start_kernel().
