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-4.9.4-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 94f0b2d4a1d0c52035aef425da5e022bd2cb1c71 # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- sh7710voipgw_defconfig # < make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/net/sched/sch_frag.c: In function 'sch_fragment': /kisskb/src/net/sched/sch_frag.c:93:10: warning: missing braces around initializer [-Wmissing-braces] struct rtable sch_frag_rt = { 0 }; ^ /kisskb/src/net/sched/sch_frag.c:93:10: warning: (near initialization for 'sch_frag_rt.dst') [-Wmissing-braces] /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-ld: kernel/sched/core.o: uses dsp instructions while previous modules use floating point instructions /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-ld: kernel/sched/core.o: uses instructions which are incompatible with instructions used in previous modules /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux-ld: failed to merge target specific data of file kernel/sched/core.o make[1]: * [/kisskb/src/Makefile:1196: vmlinux] Error 1 make: * [Makefile:215: __sub-make] Error 2 Command 'make -s -j 48 ARCH=sh O=/kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/sh4-linux/bin/sh4-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_sh7710voipgw_defconfig_sh4-gcc4.9 # Build took: 0:00:33.194980
