# # This unconditional assignment was valid outside the loop but within it # it clobbers the actual value of ret. # # To avoid this only assign "ret = -ENXIO" when actually needed. # # [ Also, the 'goto unlock_out" needs to be just a "break", so that it # does the right thing when it exits on later iterations when partial # success has happened - Linus ] # # Reported-by: Storm Dragon <stormdragon2976@gmail.com> # Link: https://lore.kernel.org/lkml/Y%2FKS6vdql2pIsCiI@hotmail.com/ # Fixes: 226fae124b2d ("vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF") # Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> # Link: https://lore.kernel.org/lkml/64981d94-d00c-4b31-9063-43ad0a384bde@t-8ch.de/ # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 ae3419fbac845b4d3f3a9fae4cc80c68d82cdf6e # < make -s -j 120 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 allyesconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_KCOV=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # Added to kconfig CONFIG_GCC_PLUGIN_STRUCTLEAK=n # Added to kconfig CONFIG_GCC_PLUGIN_RANDSTRUCT=n # Added to kconfig CONFIG_UML_NET=n # Added to kconfig CONFIG_UML_NET_ETHERTAP=n # Added to kconfig CONFIG_UML_NET_TUNTAP=n # Added to kconfig CONFIG_UML_NET_SLIP=n # Added to kconfig CONFIG_UML_NET_DAEMON=n # Added to kconfig CONFIG_UML_NET_VDE=n # Added to kconfig CONFIG_UML_NET_MCAST=n # Added to kconfig CONFIG_UML_NET_PCAP=n # Added to kconfig CONFIG_UML_NET_SLIRP=n # Added to kconfig CONFIG_GCOV_KERNEL=n # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig CONFIG_BPF_PRELOAD=n # < make -s -j 120 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 help # make -s -j 120 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 olddefconfig .config:12922:warning: override: reassigning to symbol GCC_PLUGIN_SANCOV .config:12927:warning: override: reassigning to symbol UML_NET_ETHERTAP .config:12929:warning: override: reassigning to symbol UML_NET_SLIP .config:12932:warning: override: reassigning to symbol UML_NET_MCAST .config:12934:warning: override: reassigning to symbol UML_NET_SLIRP # make -s -j 120 ARCH=um O=/kisskb/build/linus_um-allyesconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- SUBARCH=x86_64 /kisskb/src/arch/um/os-Linux/util.c:17:24: fatal error: sys/random.h: No such file or directory compilation terminated. make[3]: *** [/kisskb/src/scripts/Makefile.build:252: arch/um/os-Linux/util.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.build:494: arch/um/os-Linux] Error 2 make[2]: *** Waiting for unfinished jobs.... /kisskb/src/fs/btrfs/send.c: In function 'get_cur_inode_state': /kisskb/src/fs/btrfs/send.c:1909:13: error: 'right_gen' may be used uninitialized in this function [-Werror=maybe-uninitialized] } else if (right_gen == gen) { ^ /kisskb/src/fs/btrfs/send.c: At top level: cc1: error: unrecognized command line option '-Wno-shift-negative-value' [-Werror] cc1: all warnings being treated as errors make[4]: *** [/kisskb/src/scripts/Makefile.build:252: fs/btrfs/send.o] Error 1 make[4]: *** Waiting for unfinished jobs.... make[3]: *** [/kisskb/src/scripts/Makefile.build:494: fs/btrfs] Error 2 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.build:494: fs] Error 2 In file included from /kisskb/src/arch/x86/um/asm/processor.h:41:0, from /kisskb/src/include/linux/mutex.h:19, from /kisskb/src/include/linux/kernfs.h:11, from /kisskb/src/include/linux/sysfs.h:16, from /kisskb/src/include/linux/kobject.h:20, from /kisskb/src/include/linux/pci.h:35, from /kisskb/src/drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:26: /kisskb/src/drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c: In function 'kfd_cpumask_to_apic_id': /kisskb/src/arch/um/include/asm/processor-generic.h:94:18: error: called object is not a function or function pointer #define cpu_data (&boot_cpu_data) ^ /kisskb/src/drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_topology.c:2157:9: note: in expansion of macro 'cpu_data' return cpu_data(first_cpu_of_numa_node).apicid;
