# Merge tag 'close-range-cloexec-unshare-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux # # Pull close_range fix from Christian Brauner: # "syzbot reported a bug when asking close_range() to unshare the file # descriptor table and making all fds close-on-exec. # # If CLOSE_RANGE_UNSHARE the caller will receive a private file # descriptor table in case their file descriptor table is currently # shared before operating on the requested file descriptor range. # # For the case where the caller has requested all file descriptors to be # actually closed via e.g. close_range(3, ~0U, CLOSE_RANGE_UNSHARE) the # kernel knows that the caller does not need any of the file descriptors # anymore and will optimize the close operation by only copying all # files in the range from 0 to 3 and no others. # # However, if the caller requested CLOSE_RANGE_CLOEXEC together with # CLOSE_RANGE_UNSHARE the caller wants to still make use of the file # descriptors so the kernel needs to copy all of them and can't # optimize. # # The original patch didn't account for this and thus could cause oopses # as evidenced by the syzbot report because it assumed that all fds had # been copied. 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/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 467f8165a2b0e6accf3d0dd9c8089b1dbde29f7f # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # < make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- help # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:12861:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 8 ARCH=mips O=/kisskb/build/linus_mips-allmodconfig_mips-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/mips-linux/bin/mips-linux- /kisskb/src/lib/bitfield_kunit.c: In function 'test_bitfields_constants': /kisskb/src/lib/bitfield_kunit.c:93:1: warning: the frame size of 4224 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/soc/qcom/pdr_interface.c: In function 'pdr_restart_pd': /kisskb/src/drivers/soc/qcom/pdr_interface.c:572:9: warning: missing braces around initializer [-Wmissing-braces] struct servreg_restart_pd_req req = { 0 };
