开源软件名称:vishvananda/netlink开源软件地址:https://github.com/vishvananda/netlink开源编程语言:Go 99.9%开源软件介绍:netlink - netlink library for goThe 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 Local Build and TestYou can use go get command:
Testing dependencies:
Testing (requires root):
ExamplesAdd a new bridge and add eth1 into it: 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 Add a new ip address to loopback: 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 WorkMany 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. |
