Fix this by handling the CLOSE_RANGE_CLOEXEC case and # copying all fds if the two flags are specified together. # # This should've been caught in the selftests but the original patch # didn't cover this case and I didn't catch it during review. So in # addition to the bugfix I'm also adding selftests. They will reliably # reproduce the bug on a non-fixed kernel and allows us to catch # regressions and verify correct behavior. # # Note, the kernel selftest tree contained a bunch of changes that made # the original selftest fail to compile so there are small fixups in # here make them compile without warnings" # # * tag 'close-range-cloexec-unshare-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # selftests/core: add regression test for CLOSE_RANGE_UNSHARE \| CLOSE_RANGE_CLOEXEC # selftests/core: add test for CLOSE_RANGE_UNSHARE \| CLOSE_RANGE_CLOEXEC # selftests/core: handle missing syscall number for close_range # selftests/core: fix close_range_test build after XFAIL removal # close_range: unshare all fds for CLOSE_RANGE_UNSHARE \| CLOSE_RANGE_CLOEXEC # < /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 467f8165a2b0e6accf3d0dd9c8089b1dbde29f7f # < make -s -j 120 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 120 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/arch/sh/kernel/traps.c: In function 'nmi_trap_handler': /kisskb/src/arch/sh/kernel/traps.c:183:15: warning: unused variable 'cpu' [-Wunused-variable] unsigned int cpu = smp_processor_id(); ^ /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:1170: vmlinux] Error 1 make: * [Makefile:185: __sub-make] Error 2 Command 'make -s -j 120 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: 0:00:19.711454
