Currently we have three possibilities on how to name pid namespaces. - indirect via processes - pids - names in the filesystem We discussed this a bit in the hallway track and pids are look like the way to go. Pavel has a patch in progress to help sort this out. The practical problem we have today is that we need a way to wait for the network namespace in particular and namespaces in general to exit. At a first glance waitid(P_NS, <pid>,....) looks like a useful way to achieve this. After looking at wait a bit more it really is fundamentally just an exit status reaper of zombies, that has the option of blocking when the zombies do not yet exist. In any kind of event loop you would wait for SIGCHLD either as a signal or with signalfd. So how shall we wait for a namespace to exit? My brainstorm tonight suggests inotify_add_watch(ifd, "/proc/ns/<pid>", IN_DELETE); Eric _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
