Hello,
Hi,
as an unprivileged user one is able to keep network namespaces from expiring by opening /proc/<pid>/net/dev of other processes.
This is what I would expect.At least based on my understanding of how the various namespaces work. If something is using the namespace, it's not removed. Opening a file / device therein would count as using it.
Does that seem like problematic behavior?
No, not as such. This seems to me like a permissions issue on the /proc/<pid> directory. Read: Set the permissions such that access is restricted appropriately. -- Grant. . . . unix || die
