In that case enable_best_rng() will return an error code and # the currently active RNG will remain active. # After unregistering this might lead to crashes due to use-after-free. # # Fix this by dropping the currently active RNG, if enable_best_rng() # failed. This will result in no RNG to be active, if the next-best # one failed to initialize. # # This problem was introduced by 142a27f0a731ddcf467546960a5585970ca98e21 # # Fixes: 142a27f0a731 ("hwrng: core - Reset user selected rng by...") # Reported-by: Wirz <spam@lukas-wirz.de> # Tested-by: Wirz <spam@lukas-wirz.de> # Signed-off-by: Michael Büsch <m@bues.ch> # Cc: stable@vger.kernel.org # 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 837bf7cc3b7504385ae0e829c72e470dfc27cf6c # < make -s -j 8 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- powernv_defconfig # Added to kconfig CONFIG_PERF_EVENTS=n # yes \n \| make -s -j 8 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 8 ARCH=powerpc O=/kisskb/build/crypto_powernv_defconfig+NO_PERF_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 2 section mismatch(es).
