Merge tag 'seccomp-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull seccomp updates from Kees Cook: "There are a bunch of clean ups and selftest improvements along with two major updates to the SECCOMP_RET_USER_NOTIF filter return: EPOLLHUP support to more easily detect the death of a monitored process, and being able to inject fds when intercepting syscalls that expect an fd-opening side-effect (needed by both container folks and Chrome). The latter continued the refactoring of __scm_install_fd() started by Christoph, and in the process found and fixed a handful of bugs in various callers. - Improved selftest coverage, timeouts, and reporting - Add EPOLLHUP support for SECCOMP_RET_USER_NOTIF (Christian Brauner) - Refactor __scm_install_fd() into __receive_fd() and fix buggy callers - Introduce 'addfd' command for SECCOMP_RET_USER_NOTIF (Sargun Dhillon)" * tag 'seccomp-v5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (30 commits) selftests/seccomp: Test SECCOMP_IOCTL_NOTIF_ADDFD seccomp: Introduce addfd ioctl to seccomp user notifier fs: Expand __receive_fd() to accept existing fd pidfd: Replace open-coded receive_fd() fs: Add receive_fd() wrapper for __receive_fd() fs: Move __scm_install_fd() to __receive_fd() net/scm: Regularize compat handling of scm_detach_fds() pidfd: Add missing sock updates for pidfd_getfd() net/compat: Add missing sock updates for SCM_RIGHTS selftests/seccomp: Check ENOSYS under tracing selftests/seccomp: Refactor to use fixture variants selftests/harness: Clean up kern-doc for fixtures seccomp: Use -1 marker for end of mode 1 syscall list seccomp: Fix ioctl number for SECCOMP_IOCTL_NOTIF_ID_VALID selftests/seccomp: Rename user_trap_syscall() to user_notif_syscall() selftests/seccomp: Make kcmp() less required seccomp: Use pr_fmt selftests/seccomp: Improve calibration loop selftests/seccomp: use 90s as timeout selftests/seccomp: Expand benchmark to per-filter measurements ...
