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 ( + "fmt" + "github.com/vishvananda/netlink" +) + +func main() { + la := netlink.NewLinkAttrs() + la.Name = "foo" + mybridge := &netlink.Bridge{LinkAttrs: la} + err := netlink.LinkAdd(mybridge) + if err != nil { + fmt.Printf("could not add %s: %v\n", la.Name, err) + } + 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 ( + "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. + diff --git a/vendor/github.com/vishvananda/netlink/addr.go b/vendor/github.com/vishvananda/netlink/addr.go new file mode 100644 index 00000000..653f540d --- /dev/null +++ b/vendor/github.com/vishvananda/netlink/addr.go @@ -0,0 +1,57 @@ +package netlink + +import ( + "fmt" + "net" + "strings" +) + +// Addr represents an IP address from netlink.
