From: Tycho Andersen <tandersen@xxxxxxxxxxx> Hi all, Finally picking this back up. I looked for a location where we could put the do_notify_pidfd() call so that we'd only need one for an embarassingly long time, but couldn't find anything that worked. So, we have a new call in a similar location in v1, just using the actual helper. Perhaps this makes sense, since we're adding a new feature. Hopefully all the tests even pass this time! I looked for a bit but couldn't figure out why they don't exit(0) when something failed. I'll keep looking at that. Thoughts welcome, Tycho Tycho Andersen (3): pidfd: allow pidfd_open() on non-thread-group leaders selftests/pidfd: add non-thread-group leader tests clone: allow CLONE_THREAD | CLONE_PIDFD together include/linux/sched/signal.h | 1 + kernel/exit.c | 11 + kernel/fork.c | 7 +- kernel/pid.c | 11 +- kernel/signal.c | 2 +- tools/testing/selftests/pidfd/.gitignore | 1 + tools/testing/selftests/pidfd/Makefile | 3 +- .../selftests/pidfd/pidfd_non_tgl_test.c | 600 ++++++++++++++++++ 8 files changed, 619 insertions(+), 17 deletions(-) create mode 100644 tools/testing/selftests/pidfd/pidfd_non_tgl_test.c base-commit: 610347effc2ecb5ededf5037e82240b151f883ab -- 2.34.1
