And that in turn # caused a regression for at least Fedora 29, where NIC interfaces fail to # start when using NetworkManager. # # Since only the write side wanted the mm_struct test, ignore any failures # by __mem_open() at open time, leaving reads unaffected. The write() # time verification of the mm_struct pointer will then catch the failure # case because a NULL pointer will not match a valid 'current->mm'. # # Link: https://lore.kernel.org/netdev/YMjTlp2FSJYvoyFa@unreal/ # Fixes: 591a22c14d3f ("proc: Track /proc/$pid/attr/ opener mm_struct") # Reported-and-tested-by: Leon Romanovsky <leon@kernel.org> # Cc: Kees Cook <keescook@chromium.org> # Cc: Christian Brauner <christian.brauner@ubuntu.com> # Cc: Andrea Righi <andrea.righi@canonical.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 94f0b2d4a1d0c52035aef425da5e022bd2cb1c71 # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 24 ARCH=s390 O=/kisskb/build/linus_s390-allyesconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/arch/s390/kernel/traps.c: In function '__do_pgm_check': /kisskb/src/arch/s390/kernel/traps.c:359:1: warning: '__do_pgm_check' uses dynamic stack allocation } ^ /kisskb/src/arch/s390/kernel/syscall.c: In function '__do_syscall': /kisskb/src/arch/s390/kernel/syscall.c:169:1: warning: '__do_syscall' uses dynamic stack allocation } ^ /kisskb/src/drivers/gpu/drm/rockchip/cdn-dp-core.c:1124:12: warning: 'cdn_dp_resume' defined but not used [-Wunused-function] static int cdn_dp_resume(struct device *dev) ^~~~~~~~~~~~~ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
