grant-and-claim-netns-interfaces

Description

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 $PID is discovered by running the executable configured with GranteePIDDiscovery

Prerequisites

• libmnl-dev (debian) or libmnl-devel (fedora)
• libcap-dev (debian) or libcap-devel (fedora)
