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-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 837bf7cc3b7504385ae0e829c72e470dfc27cf6c # < make -s -j 10 ARCH=powerpc O=/kisskb/build/crypto_ppc64e_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc64e_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/crypto_ppc64e_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1268:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2497:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1819:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/bridge/br_netlink.c: In function 'br_afspec': /kisskb/src/net/bridge/br_netlink.c:635:7: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:340:21: note: 'pdeo' was declared here /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2041:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here /kisskb/src/drivers/net/tun.c: In function 'tun_get_user': /kisskb/src/drivers/net/tun.c:1827:30: warning: 'copylen' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/net/tun.c:1737:46: warning: 'linear' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0xd8cf00) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xe00000) Image Name: Linux-4.17.0-rc1-g837bf7c Created: Mon Jun 18 09:30:14 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 5787188 Bytes = 5651.55 kB = 5.52 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/crypto_ppc64e_defconfig_powerpc # Build took: 0:02:06.521049
