Andrei Budnik created MESOS-8037: ------------------------------------ Summary: ns::clone should spawn process, which is a direct child Key: MESOS-8037 URL: https://issues.apache.org/jira/browse/MESOS-8037 Project: Mesos Issue Type: Improvement Reporter: Andrei Budnik
`ns::clone` does double-fork in order to be able to enter given PID namespace and returns grandchild's pid, which is not a direct child of a parent process, hence parent process can not retrieve status of an exited grandchild process. As second fork is implemented via `os::clone`, we can pass `CLONE_PARENT` flag. Also, we have to handle both intermediate child process and grandchild process to avoid zombies. Motivation behind this improvement is that both `docker exec` and `LXC attach` can enter process' PID namespace, while still controlling child's status code. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
