These architectures should use probe_read_{user,kernel}_str # helpers. # # For backward compatibility, the problematic functions are still # available on architectures where the user and kernel address spaces # are not overlapping. This is defined # CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. # # At the moment, these backward compatible functions are enabled only on # x86_64, arm, and arm64. Let's do it also on powerpc that has the non # overlapping address space as well. # # Fixes: 0ebeea8ca8a4 ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work") # Signed-off-by: Petr Mladek <pmladek@suse.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200527122844.19524-1-pmladek@suse.com # < /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 c72f04dc46f466a7574a204bf2e965aa1c5cf277 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_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:805: Warning: invalid register expression INFO: Uncompressed kernel (size 0x596080) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x596080) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5859d0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x596080) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x596080) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.7.0-rc2-14564-gc72f04dc4 Created: Fri May 29 00:44:58 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2814705 Bytes = 2748.74 KiB = 2.68 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.7.0-rc2-14564-gc72f04dc4 Created: Fri May 29 00:44:58 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2846035 Bytes = 2779.33 KiB = 2.71 MiB Load Address: 00600000 Entry Point: 006017dc Image Name: Linux-5.7.0-rc2-14564-gc72f04dc4 Created: Fri May 29 00:44:58 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2846214 Bytes = 2779.51 KiB = 2.71 MiB Load Address: 00600000 Entry Point: 00601a18 Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc-gcc5 # Build took: 0:00:52.083452
