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/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 467f8165a2b0e6accf3d0dd9c8089b1dbde29f7f # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_mpc85xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_mpc85xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/kernel.h:10:0, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:22:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] #define IS_ERR_VALUE(x) unlikely((unsigned long)(void )(x) >= (unsigned long)-MAX_ERRNO) ^ /kisskb/src/include/linux/compiler.h:78:42: note: in definition of macro 'unlikely' # define unlikely(x) __builtin_expect(!!(x), 0) ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:139:6: note: in expansion of macro 'IS_ERR_VALUE' if (IS_ERR_VALUE(fep->ring_mem_addr)) ^ cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory compilation terminated. make[2]: [scripts/Makefile.lib:326: arch/powerpc/boot/dts/fsl/mpc8540ads.dtb] Error 1 make[2]: * Waiting for unfinished jobs.... make[1]: * [arch/powerpc/Makefile:293: zImage] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_mpc85xx_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_mpc85xx_defconfig_powerpc-gcc4.9 # Build took: 0:01:15.306898
