This allows process # managers to know when a (non-parent) process dies in a race-free # way. # # The notification mechanism used follows the same logic that is # currently used when the parent of a task is notified of a child's # death. With this patchset it is possible to put pidfds in an # {e}poll loop and get reliable notifications for process (i.e. # thread-group) exit. # # - The second feature compliments the first one by making it possible # to retrieve pollable pidfds for processes that were not created # using CLONE_PIDFD. # # A lot of processes get created with traditional PID-based calls # such as fork() or clone() (without CLONE_PIDFD). For these # processes a caller can currently not create a pollable pidfd. This # is a problem for Android's low memory killer (LMK) and service # managers such as systemd. # # Both patchsets are accompanied by selftests. # # It's perhaps worth noting that the work done so far and the work done # in this branch for pidfd_open() and polling support do already see # some adoption: # # - Android is in the process of backporting this work to all their LTS # kernels [1] # # - Service managers make use of pidfd_send_signal but will need to # wait until we enable waiting on pidfds for full adoption. # # - And projects I maintain make use of both pidfd_send_signal and # CLONE_PIDFD [2] and will use polling support and pidfd_open() too" # # [1] https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.9+backport%22 # https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.14+backport%22 # https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.19+backport%22 # # [2] https://github.com/lxc/lxc/blob/aab6e3eb73c343231cdde775db938994fc6f2803/src/lxc/start.c#L1753 # # * tag 'pidfd-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # tests: add pidfd_open() tests # arch: wire-up pidfd_open() # pid: add pidfd_open() # pidfd: add polling selftests # pidfd: add polling support # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 5450e8a316a64cddcbc15f90733ebc78aa736545 # < make -s -j 120 ARCH=sh O=/kisskb/build/linus_r7785rp_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- r7785rp_defconfig # make -s -j 120 ARCH=sh O=/kisskb/build/linus_r7785rp_defconfig_sh4 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh4/../sh3/../../entry-common.S:385: Warning: overflow in branch to syscall_exit_work;
