A system utility for moving network interfaces between network namespaces. An example of this would be to move a physical interface from the root netns into a netns created by an unprivileged user, which lets the user configure the interface, giving flexibility in immutable or otherwise access-restricted environments.
In this program, the namespaces are named as such,
- "Claimee" - This is the netns in which the program is started. Namely, the
one linked by
/proc/self/ns/net. - "Grantee" - This netns is the one linked by
/proc/$PID/ns/net, in which$PIDis discovered by running the executable configured withGranteePIDDiscovery
