However, it doesn't add these to # __clear_user(), which is used in the ptrace regset code. # # As there's only one direct user of __clear_user(), and the time taken to # set the AMR for KUAP purposes is going to dominate the cost of a quick # access_ok(), there's not much point having a separate path. # # Rename __clear_user() to clear_user_asm(), and make __clear_user() just # call clear_user(). # # Reported-by: syzbot+f25ecf4b2982d8c7a640@syzkaller-ppc64.appspotmail.com # Reported-by: Daniel Axtens <dja@axtens.net> # Suggested-by: Michael Ellerman <mpe@ellerman.id.au> # Fixes: de78a9c42a79 ("powerpc: Add a framework for Kernel Userspace Access Protection") # Signed-off-by: Andrew Donnellan <ajd@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191209132221.15328-1-ajd@linux.ibm.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 d04cb29a7ef9e90cb0e4f16953f2d7484a9a48fb # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-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 # yes \n \| make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_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 32 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-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:208:9: 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; ^ INFO: Uncompressed kernel (size 0x8e1308) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x900000) Completed OK # rm -rf /kisskb/build/powerpc-fixes_pmac32_defconfig+KVM_powerpc-gcc5 # Build took: 0:01:50.942717
