By change, it used to work because BOOTX # buffer is mapped 1:1 at address 0x81000000 by the bootloader, and # btext_setup_display() sets virt addr same as phys addr. # # But since commit 215b823707ce ("powerpc/32s: set up an early static # hash table for KASAN."), a temporary page table overrides the # bootloader mapping. # # This 0x81000000 is also problematic with the newly implemented # Kernel Userspace Access Protection (KUAP) because it is within user # address space. # # This patch fixes those issues by properly setting disp_BAT through # a call to btext_prepare_BAT(), allowing setup_disp_bat() to # properly setup BAT3 for early bootx screen buffer access. # # Reported-by: Mathieu Malaterre <malat@debian.org> # Fixes: 215b823707ce ("powerpc/32s: set up an early static hash table for KASAN.") # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Tested-by: Mathieu Malaterre <malat@debian.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /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 c21f5a9ed85ca3e914ca11f421677ae9ae0d04b0 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_HUGETLB+4K_PAGES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # Added to kconfig CONFIG_PPC_64K_PAGES=n # Added to kconfig CONFIG_PPC_4K_PAGES=y # Added to kconfig CONFIG_HUGETLBFS=n # yes \n | make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_HUGETLB+4K_PAGES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_HUGETLB+4K_PAGES_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- WARNING: vmlinux.o(.text+0x39c6): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup() The function start_here_multiplatform() references the function __init .early_setup().
