It allows to efficiently close a # range of file descriptors up to all file descriptors of a calling # task. # # This is coordinated with the FreeBSD folks which have copied our # version of this syscall and in the meantime have already merged it in # April 2019: # # https://reviews.freebsd.org/D21627 # https://svnweb.freebsd.org/base?view=revision&revision=359836 # # The syscall originally came up in a discussion around the new mount # API and making new file descriptor types cloexec by default. During # this discussion, Al suggested the close_range() syscall. # # First, it helps to close all file descriptors of an exec()ing task. # This can be done safely via (quoting Al's example from [1] verbatim): # # /* that exec is sensitive / # unshare(CLONE_FILES); # / we don't want anything past stderr here / # close_range(3, ~0U); # execve(....); # # The code snippet above is one way of working around the problem that # file descriptors are not cloexec by default. This is aggravated by the # fact that we can't just switch them over without massively regressing # userspace. For a whole class of programs having an in-kernel method of # closing all file descriptors is very helpful (e.g. demons, service # managers, programming language standard libraries, container managers # etc.). # # Second, it allows userspace to avoid implementing closing all file # descriptors by parsing through /proc/<pid>/fd/ and calling close() on # each file descriptor and other hacks. From looking at various # large(ish) userspace code bases this or similar patterns are very # common in service managers, container runtimes, and programming # language runtimes/standard libraries such as Python or Rust. # # In addition, the syscall will also work for tasks that do not have # procfs mounted and on kernels that do not have procfs support compiled # in. In such situations the only way to make sure that all file # descriptors are closed is to call close() on each file descriptor up # to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery. # # Based on Linus' suggestion close_range() also comes with a new flag # CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping # right before exec. This would usually be expressed in the sequence: # # unshare(CLONE_FILES); # close_range(3, ~0U); # # as pointed out by Linus it might be desirable to have this be a part # of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which # gets especially handy when we're closing all file descriptors above a # certain threshold. # # Test-suite as always included" # # * tag 'close-range-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # tests: add CLOSE_RANGE_UNSHARE tests # close_range: add CLOSE_RANGE_UNSHARE # tests: add close_range() tests # arch: wire-up close_range() # open: add close_range() # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 4f30a60aa78410496e5ffe632a371c00f0d83a8d # < make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0x233E66BA # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig .config:5537:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:26: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:26: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum Error: /kisskb/src/arch/arm64/boot/dts/intel/socfpga_agilex.dtsi:313.15-16 syntax error FATAL ERROR: Unable to parse input tree make[3]: * [scripts/Makefile.lib:314: arch/arm64/boot/dts/intel/socfpga_agilex_socdk.dtb] Error 1 make[2]: * [/kisskb/src/scripts/Makefile.build:497: arch/arm64/boot/dts/intel] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1316: dtbs] Error 2 make[1]: * Waiting for unfinished jobs.... make: * [Makefile:185: __sub-make] Error 2 Command 'make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 # Build took: 0:00:31.355251
