# netlink - netlink library for go #
[![Build Status](https://travis-ci.org/vishvananda/netlink.png?branch=master)](https://travis-ci.org/vishvananda/netlink) [![GoDoc](https://godoc.org/github.com/vishvananda/netlink?status.svg)](https://godoc.org/github.com/vishvananda/netlink)
The netlink package provides a simple netlink library for go. Netlink
is the interface a user-space program in linux uses to communicate with
the kernel. It can be used to add and remove interfaces, set ip addresses
and routes, and configure ipsec. Netlink communication requires elevated
privileges, so in most cases this code needs to be run as root. Since
low-level netlink messages are inscrutable at best, the library attempts
to provide an api that is loosely modeled on the CLI provided by iproute2.
Actions like `ip link add` will be accomplished via a similarly named
function like AddLink(). This library began its life as a fork of the
netlink functionality in
[docker/libcontainer](https://github.com/docker/libcontainer) but was
heavily rewritten to improve testability, performance, and to add new
functionality like ipsec xfrm handling.
## Local Build and Test ##
You can use go get command:
go get github.com/vishvananda/netlink
Testing dependencies:
go get github.com/vishvananda/netns
Testing (requires root):
sudo -E go test github.com/vishvananda/netlink
## Examples ##
Add a new bridge and add eth1 into it:
```go
package main
import (
"net"
"github.com/vishvananda/netlink"
)
func main() {
la := netlink.NewLinkAttrs()
la.Name = "foo"
mybridge := &netlink.Bridge{la}}
_ := netlink.LinkAdd(mybridge)
eth1, _ := netlink.LinkByName("eth1")
netlink.LinkSetMaster(eth1, mybridge)
}
```
Note `NewLinkAttrs` constructor, it sets default values in structure. For now
it sets only `TxQLen` to `-1`, so kernel will set default by itself. If you're
using simple initialization(`LinkAttrs{Name: "foo"}`) `TxQLen` will be set to
`0` unless you specify it like `LinkAttrs{Name: "foo", TxQLen: 1000}`.
Add a new ip address to loopback:
```go
package main
import (
"net"
"github.com/vishvananda/netlink"
)
func main() {
lo, _ := netlink.LinkByName("lo")
addr, _ := netlink.ParseAddr("169.254.169.254/32")
netlink.AddrAdd(lo, addr)
}
```
## Future Work ##
Many pieces of netlink are not yet fully supported in the high-level
interface. Aspects of virtually all of the high-level objects don't exist.
Many of the underlying primitives are there, so its a matter of putting
the right fields into the high-level objects and making sure that they
are serialized and deserialized correctly in the Add and List methods.
There are also a few pieces of low level netlink functionality that still
need to be implemented. Routing rules are not in place and some of the
more advanced link types. Hopefully there is decent structure and testing
in place to make these fairly straightforward to add.

# netns - network namespaces in go #
The netns package provides an ultra-simple interface for handling
network namespaces in go. Changing namespaces requires elevated
privileges, so in most cases this code needs to be run as root.
## Local Build and Test ##
You can use go get command:
go get github.com/vishvananda/netns
Testing (requires root):
sudo -E go test github.com/vishvananda/netns
## Example ##
```go
package main
import (
"fmt"
"net"
"runtime"
"github.com/vishvananda/netns"
)
func main() {
// Lock the OS Thread so we don't accidentally switch namespaces
runtime.LockOSThread()
defer runtime.UnlockOSThread()
// Save the current network namespace
origns, _ := netns.Get()
defer origns.Close()
// Create a new network namespace
newns, _ := netns.New()
netns.Set(newns)
defer newns.Close()
// Do something with the network namespace
ifaces, _ := net.Interfaces()
fmt.Printf("Interfaces: %v\n", ifaces)
// Switch back to the original namespace
netns.Set(origns)
}
```
