The flag could either be XOR with SECCOMP_USER_NOTIF_FLAG_PIDFD, or could require both. Alternatively, we can rename SECCOMP_USER_NOTIF_FLAG_PIDFD to SECCOMP_USER_NOTIF_FLAG_GROUP_LEADER_PIDFD. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
