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/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-gcc --version # < /opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux-ld --version # < git log --format=%s --max-count=1 a9dce6679d736cb3d612af39bab9f31f8db66f9b # < make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=xtensa O=/kisskb/build/linus_xtensa-allmodconfig_xtensa CROSS_COMPILE=/opt/cross/kisskb/br-xtensa-full-2016.08-613-ge98b4dd/bin/xtensa-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] /kisskb/src/arch/xtensa/mm/mmu.c: In function 'init_pmd': /kisskb/src/arch/xtensa/mm/mmu.c:36:9: warning: format '%zu' expects argument of type 'size_t', but argument 3 has type 'long unsigned int' [-Wformat=] panic("%s: Failed to allocate %zu bytes align=%lx\n", ^ /kisskb/src/arch/xtensa/kernel/pci.c:45:32: warning: 'pci_ctrl_tail' defined but not used [-Wunused-variable] static struct pci_controller *pci_ctrl_tail = &pci_ctrl_head; ^ ./usr/include/asm/setup.h:17: userspace cannot reference function or variable defined in the kernel /kisskb/src/drivers/char/tpm/tpm2-cmd.c: In function 'tpm2_unseal_trusted': /kisskb/src/drivers/char/tpm/tpm2-cmd.c:670:2: warning: 'blob_handle' may be used uninitialized in this function [-Wmaybe-uninitialized] tpm2_flush_context(chip, blob_handle); ^ /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret == -EOPNOTSUPP) ^ /kisskb/src/drivers/input/joystick/analog.c:172:2: warning: #warning Precise timer not defined for this architecture.
