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/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 467f8165a2b0e6accf3d0dd9c8089b1dbde29f7f # < make -s -j 32 ARCH=arm O=/kisskb/build/linus_rpc_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- rpc_defconfig # < make -s -j 32 ARCH=arm O=/kisskb/build/linus_rpc_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- help # make -s -j 32 ARCH=arm O=/kisskb/build/linus_rpc_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- olddefconfig # make -s -j 32 ARCH=arm O=/kisskb/build/linus_rpc_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- /kisskb/src/drivers/tty/vt/vt_ioctl.c: In function 'vt_ioctl': /kisskb/src/drivers/tty/vt/vt_ioctl.c:1019:1: internal compiler error: Max. number of generated reload insns per insn is achieved (90) } ^ Please submit a full bug report, with preprocessed source if appropriate.
