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/nds32le-linux/bin/nds32le-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-ld --version # < git log --format=%s --max-count=1 94f0b2d4a1d0c52035aef425da5e022bd2cb1c71 # < make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allmodconfig # < make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- help # make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- olddefconfig # make -s -j 48 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/nds32/kernel/setup.c: In function 'setup_memory': /kisskb/src/arch/nds32/kernel/setup.c:247:26: warning: unused variable 'region' [-Wunused-variable] struct memblock_region *region; ^~~~~~ /kisskb/src/drivers/input/joystick/analog.c:160:2: warning: #warning Precise timer not defined for this architecture.
