Even if a pid is recycled the handle # will not change. For a start these fds can be used to send signals to # the processes they refer to. # # With the ability to use /proc/<pid> fds as stable handles on struct # pid we can fix a long-standing issue where after a process has exited # its pid can be reused by another process. If a caller sends a signal # to a reused pid it will end up signaling the wrong process. # # With this patchset we enable a variety of use cases. One obvious # example is that we can now safely delegate an important part of # process management - sending signals - to processes other than the # parent of a given process by sending file descriptors around via scm # rights and not fearing that the given process will have been recycled # in the meantime. It also allows for easy testing whether a given # process is still alive or not by sending signal 0 to a pidfd which is # quite handy. # # There has been some interest in this feature e.g. from systems # management (systemd, glibc) and container managers. I have requested # and gotten comments from glibc to make sure that this syscall is # suitable for their needs as well. In the future I expect it to take on # most other pid-based signal syscalls. But such features are left for # the future once they are needed. # # This has been sitting in linux-next for quite a while and has not # caused any issues. It comes with selftests which verify basic # functionality and also test that a recycled pid cannot be signaled via # a pidfd. # # Jon has written about a prior version of this patchset. It should # cover the basic functionality since not a lot has changed since then: # # https://lwn.net/Articles/773459/ # # The commit message for the syscall itself is extensively documenting # the syscall, including it's functionality and extensibility" # # * tag 'pidfd-v5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # selftests: add tests for pidfd_send_signal() # signal: add pidfd_send_signal() syscall # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a9dce6679d736cb3d612af39bab9f31f8db66f9b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x3D3F91DE # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig # yes \n | make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] In file included from /kisskb/src/arch/powerpc/xmon/xmon.c:67:0: /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_powerpc': /kisskb/src/arch/powerpc/xmon/dis-asm.h:20:9: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ^ /kisskb/src/arch/powerpc/xmon/dis-asm.h: In function 'print_insn_spu': /kisskb/src/arch/powerpc/xmon/dis-asm.h:26:9: warning: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'long unsigned int' [-Wformat=] printf("%.8x", insn); ^ arch/powerpc/perf/perf_regs.o: In function `.perf_reg_value': (.text.perf_reg_value+0xc4): undefined reference to `.is_sier_available' make[1]: *** [/kisskb/src/Makefile:1014: vmlinux] Error 1 make: *** [Makefile:160: sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_powerpc-randconfig_powerpc-gcc5 # Build took: 0:02:36.536977
