Functions

func GetLinuxInterfaceIndex

func GetLinuxInterfaceIndex(ifName string) int

GetLinuxInterfaceIndex returns the index of a Linux interface identified by its name. In Linux, interface index is a positive integer that starts at one, zero is never used. Function returns negative number in case of a failure, such as when the interface doesn't exist. TODO: move to the package with network utilities

Types

type LinuxInterfaceConfig

type LinuxInterfaceConfig struct {
	// contains filtered or unexported fields
}

LinuxInterfaceConfig is used to cache the configuration of Linux interfaces.

type LinuxInterfaceConfigurator

type LinuxInterfaceConfigurator struct {
	Log logging.Logger

	/* time measurement */
	Stopwatch *measure.Stopwatch // timer used to measure and store time
	// contains filtered or unexported fields
}

LinuxInterfaceConfigurator runs in the background in its own goroutine where it watches for any changes in the configuration of interfaces as modelled by the proto file "model/interfaces/interfaces.proto" and stored in ETCD under the key "/vnf-agent/{vnf-agent}/linux/config/v1/interface". Updates received from the northbound API are compared with the Linux network configuration and differences are applied through the Netlink API.

func (*LinuxInterfaceConfigurator) Close

func (plugin *LinuxInterfaceConfigurator) Close() error

Close stops all goroutines started by linuxplugin

func (*LinuxInterfaceConfigurator) ConfigureLinuxInterface

func (plugin *LinuxInterfaceConfigurator) ConfigureLinuxInterface(iface *intf.LinuxInterfaces_Interface) error

ConfigureLinuxInterface reacts to a new northbound Linux interface config by creating and configuring the interface in the host network stack through Netlink API.

func (*LinuxInterfaceConfigurator) DeleteLinuxInterface

func (plugin *LinuxInterfaceConfigurator) DeleteLinuxInterface(iface *intf.LinuxInterfaces_Interface) error

DeleteLinuxInterface reacts to a removed NB configuration of a Linux interface.

func (*LinuxInterfaceConfigurator) Init

func (plugin *LinuxInterfaceConfigurator) Init(ifIndexes ifaceidx.LinuxIfIndexRW) error

Init linuxplugin and start go routines

func (*LinuxInterfaceConfigurator) LookupLinuxInterfaces

func (plugin *LinuxInterfaceConfigurator) LookupLinuxInterfaces() error

LookupLinuxInterfaces looks up all currently unmanaged Linux interfaces in the current namespace and registers them into the name-to-index mapping. Furthermore, it triggers goroutine that will watch for newly added interfaces (by another party) unless it is already running.

func (*LinuxInterfaceConfigurator) ModifyLinuxInterface

func (plugin *LinuxInterfaceConfigurator) ModifyLinuxInterface(newConfig *intf.LinuxInterfaces_Interface,
	oldConfig *intf.LinuxInterfaces_Interface) error

ModifyLinuxInterface applies changes in the NB configuration of a Linux interface into the host network stack through Netlink API.

func (*LinuxInterfaceConfigurator) Resync

func (plugin *LinuxInterfaceConfigurator) Resync(interfaces []*interfaces.LinuxInterfaces_Interface) error

Resync configures an initial set of interfaces. Existing Linux interfaces are registered and potentially re-configured.

type Microservice

type Microservice struct {
	// contains filtered or unexported fields
}

Microservice is used to store PID and ID of the container running a given microservice.
