This can cause the child to erroneously # allocate keys that were already allocated. Any allocated execute-only # key is lost as well. # # Add code; called by dup_mmap(), to copy the pkey state from parent to # child explicitly. # # This problem was originally found by Dave Hansen on x86, which turns # out to be a problem on powerpc as well. # # Fixes: cf43d3b26452 ("powerpc: Enable pkey subsystem") # Cc: stable@vger.kernel.org # v4.16+ # Signed-off-by: Ram Pai <linuxram@us.ibm.com> # Reviewed-by: Thiago Jung Bauermann <bauerman@linux.ibm.com> # [mpe: Return early if pkey_disabled is true] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 416b2bfbaccf8fd50c8e77778bd47f95f12f13d9 # < make -s -j 80 ARCH=sparc64 O=/kisskb/build/powerpc-next_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- defconfig # make -s -j 80 ARCH=sparc64 O=/kisskb/build/powerpc-next_sparc64-defconfig_sparc64 CROSS_COMPILE=/opt/cross/kisskb/br-sparc64-full-2016.08-613-ge98b4dd/bin/sparc64-linux- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. kernel: arch/sparc/boot/image is ready WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. kernel: arch/sparc/boot/zImage is ready Completed OK # rm -rf /kisskb/build/powerpc-next_sparc64-defconfig_sparc64 # Build took: 0:01:10.408648
