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/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 416b2bfbaccf8fd50c8e77778bd47f95f12f13d9 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/arch/powerpc/kernel/ptrace.c:24: In function 'user_regset_copyin', inlined from 'vr_set' at /kisskb/src/arch/powerpc/kernel/ptrace.c:619:9: /kisskb/src/include/linux/regset.h:295:4: error: 'memcpy' offset [-527, -529] is out of the bounds [0, 16] of object 'vrsave' with type 'union <anonymous>' [-Werror=array-bounds] memcpy(data, kbuf, copy); ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/powerpc/kernel/ptrace.c: In function 'vr_set': /kisskb/src/arch/powerpc/kernel/ptrace.c:614:5: note: 'vrsave' declared here } vrsave; ^~~~~~ In file included from /kisskb/src/arch/powerpc/kernel/ptrace.c:24: In function 'user_regset_copyout', inlined from 'vr_get' at /kisskb/src/arch/powerpc/kernel/ptrace.c:572:9: /kisskb/src/include/linux/regset.h:270:4: error: 'memcpy' offset [-527, -529] is out of the bounds [0, 16] of object 'vrsave' with type 'union <anonymous>' [-Werror=array-bounds] memcpy(kbuf, data, copy); ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/powerpc/kernel/ptrace.c: In function 'vr_get': /kisskb/src/arch/powerpc/kernel/ptrace.c:567:5: note: 'vrsave' declared here } vrsave; ^~~~~~ cc1: all warnings being treated as errors make[3]: * [/kisskb/src/scripts/Makefile.build:293: arch/powerpc/kernel/ptrace.o] Error 1 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:518: arch/powerpc/kernel] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1060: arch/powerpc] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:152: sub-make] Error 2 Command 'make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next_ppc6xx_defconfig_powerpc-gcc8 # Build took: 0:01:09.276006
