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/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 af3d0a68698c7e5df8b72267086b23422a3954bb # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- allnoconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_powerpc-allnoconfig_powerpc-gcc4.6 # Build took: 0:00:34.668128
