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-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 c72f04dc46f466a7574a204bf2e965aa1c5cf277 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- pmac32_defconfig # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM=y # Added to kconfig CONFIG_KVM_BOOK3S_32=m # Added to kconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4087:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/sound/ppc/pmac.h:12:0, from /kisskb/src/sound/ppc/awacs.c:16: /kisskb/src/sound/ppc/awacs.c: In function 'snd_pmac_awacs_init': /kisskb/src/include/sound/control.h:218:2: warning: 'speaker_vol' may be used uninitialized in this function [-Wmaybe-uninitialized] return _snd_ctl_add_slave(master, slave, 0); ^ /kisskb/src/sound/ppc/awacs.c:873:36: note: 'speaker_vol' was declared here struct snd_kcontrol master_vol, speaker_vol; ^ /kisskb/src/block/genhd.c: In function 'diskstats_show': /kisskb/src/block/genhd.c:1617:1: warning: the frame size of 1192 bytes is larger than 1024 bytes [-Wframe-larger-than=] } ^ /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1652:6: note: 'oldval' was declared here int oldval, ret; ^ /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c: In function 'drm_dp_mst_dsc_aux_for_port': /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5497:9: warning: missing braces around initializer [-Wmissing-braces] struct drm_dp_desc desc = { 0 }; ^ /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5497:9: warning: (near initialization for 'desc.ident') [-Wmissing-braces] ERROR: modpost: "sysrq_mask" [drivers/tty/serial/serial_core.ko] undefined! make[2]: * [/kisskb/src/scripts/Makefile.modpost:94: __modpost] Error 1 make[1]: * [/kisskb/src/Makefile:1319: modules] Error 2 make[1]: * Waiting for unfinished jobs....
