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/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < /opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-ld --version # < git log --format=%s --max-count=1 a9dce6679d736cb3d612af39bab9f31f8db66f9b # < make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # yes \n \| make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- /kisskb/src/arch/arc/boot/dts/axs10x_mb.dtsi:221.15-225.6: Warning (i2c_bus_reg): /axs10x_mb/i2c@0x1f000/eeprom@0x54: I2C bus unit address format error, expected "54" /kisskb/src/arch/arc/boot/dts/axs10x_mb.dtsi:227.15-231.6: Warning (i2c_bus_reg): /axs10x_mb/i2c@0x1f000/eeprom@0x57: I2C bus unit address format error, expected "57" /kisskb/src/arch/arc/mm/tlb.c: In function 'do_tlb_overlap_fault': /kisskb/src/arch/arc/mm/tlb.c:914:2: warning: variable length array 'pd0' is used [-Wvla] unsigned int pd0[mmu->ways]; ^ In file included from /kisskb/src/arch/arc/include/asm/atomic.h:16:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/arc/include/asm/bitops.h:429, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:12, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/module.h:9, from /kisskb/src/net/core/filter.c:24: /kisskb/src/net/core/filter.c: In function 'bpf_clear_redirect_map': /kisskb/src/arch/arc/include/asm/cmpxchg.h:95:29: warning: value computed is not used [-Wunused-value] #define cmpxchg(ptr, o, n) ((typeof((ptr)))__cmpxchg((ptr), \ ^ /kisskb/src/net/core/filter.c:3481:4: note: in expansion of macro 'cmpxchg' cmpxchg(&ri->map, map, NULL); ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4315:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ In file included from /kisskb/src/arch/arc/include/asm/atomic.h:16:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/arc/include/asm/bitops.h:429, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:12, from /kisskb/src/include/linux/list.h:9, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/nfs/nfs3acl.c:2: /kisskb/src/fs/nfs/nfs3acl.c: In function 'nfs3_abort_get_acl': /kisskb/src/arch/arc/include/asm/cmpxchg.h:95:29: warning: value computed is not used [-Wunused-value] #define cmpxchg(ptr, o, n) ((typeof((ptr)))__cmpxchg((ptr), \ ^ /kisskb/src/fs/nfs/nfs3acl.c:44:2: note: in expansion of macro 'cmpxchg' cmpxchg(p, sentinel, ACL_NOT_CACHED); ^ /kisskb/src/fs/fs_parser.c: In function 'fs_validate_description': /kisskb/src/fs/fs_parser.c:413:6: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'int' [-Wformat=] pr_err("VALIDATE %s: e[%lu] enum val for %s\n", ^ In file included from /kisskb/src/arch/arc/include/asm/atomic.h:16:0, from /kisskb/src/include/linux/atomic.h:7, from /kisskb/src/include/asm-generic/bitops/lock.h:5, from /kisskb/src/arch/arc/include/asm/bitops.h:429, from /kisskb/src/include/linux/bitops.h:19, from /kisskb/src/include/linux/kernel.h:12, from /kisskb/src/fs/posix_acl.c:13: /kisskb/src/fs/posix_acl.c: In function 'get_acl': /kisskb/src/arch/arc/include/asm/cmpxchg.h:95:29: warning: value computed is not used [-Wunused-value] #define cmpxchg(ptr, o, n) ((typeof(*(ptr)))__cmpxchg((ptr), \ ^ /kisskb/src/fs/posix_acl.c:147:3: note: in expansion of macro 'cmpxchg' cmpxchg(p, sentinel, ACL_NOT_CACHED); ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:00:58.831453
