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() (the regset code), # 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 __arch_clear_user(), 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> # [mpe: Use __arch_clear_user() for the asm version like arm64 & nds32] # 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 61e3acd8c693a14fc69b824cb5b08d02cb90a6e7 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_ksi8560_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/ksi8560_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_ksi8560_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x4d75a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4c6f10) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.5.0-rc1-g61e3acd8c693 Created: Tue Dec 17 01:39:01 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2501985 Bytes = 2443.34 KiB = 2.39 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.5.0-rc1-g61e3acd8c693 Created: Tue Dec 17 01:39:01 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2531775 Bytes = 2472.44 KiB = 2.41 MiB Load Address: 00500000 Entry Point: 00500314 Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_ksi8560_defconfig_powerpc-gcc5 # Build took: 0:00:37.421155
