It # turns out that the workaround got the assembly wrong and we end up # doing count + initial cycles of the loop instead of just count. # # This obviously causes corruption, either by overwriting the source # that is yet to be processed, or writing over the end of the buffer. # # On CPUs that don't require the workaround only ECB is affected. # On Nano CPUs both ECB and CBC are affected. # # This patch fixes it by doing the subtraction prior to the assembly. # # Fixes: a76c1c23d0c3 ("crypto: padlock-aes - work around Nano CPU...") # Cc: <stable@vger.kernel.org> # Reported-by: Jamie Heilman <jamie@audible.transient.net> # Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 46d8c4b28652d35dc6cfb5adf7f54e102fc04384 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 2 section mismatch(es).
