Since the information exposed by this # attribute cannot be cached it is better to ward off access to this # attribute from users who don't need to access to these performance # statistics. # # Hence update the access mode of 'perf_stats' attribute to be only # readable by root users. # # Fixes: 2d02bf835e57 ("powerpc/papr_scm: Fetch nvdimm performance stats from PHYP") # Reported-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Reviewed-by: Ira Weiny <ira.weiny@intel.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200907110540.21349-1-vaibhav@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 0460534b532e5518c657c7d6492b9337d975eaa3 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_acadia_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 40x/acadia_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_acadia_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_acadia_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_40x_acadia_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x5389d8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.9.0-rc1-g0460534b532e Created: Thu Sep 10 23:37:53 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2653910 Bytes = 2591.71 KiB = 2.53 MiB Load Address: 00600000 Entry Point: 006017dc Completed OK # rm -rf /kisskb/build/powerpc-fixes_40x_acadia_defconfig_powerpc-gcc5 # Build took: 0:00:53.283579
