Functions

func FmtDefineAddress

func FmtDefineAddress(name string, addr []byte) string

FmtDefineAddress returns the a define string from the given name and addr. Example: fmt.Print(FmtDefineAddress("foo", []byte{1, 2, 3})) // "#define foo { .addr = { 0x1, 0x2, 0x3 } }\n"

func NewHeaderfileWriter

func NewHeaderfileWriter(p WriterParams) (datapath.ConfigWriter, error)

Types

type HeaderfileWriter

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

HeaderfileWriter is a wrapper type which implements datapath.ConfigWriter. It manages writing of configuration of datapath program headerfiles.

func (*HeaderfileWriter) WriteEndpointConfig

func (h *HeaderfileWriter) WriteEndpointConfig(w io.Writer, e datapath.EndpointConfiguration) error

WriteEndpointConfig writes the BPF configuration for the endpoint to a writer.

func (*HeaderfileWriter) WriteNetdevConfig

func (h *HeaderfileWriter) WriteNetdevConfig(w io.Writer, cfg datapath.DeviceConfiguration) error

WriteNetdevConfig writes the BPF configuration for the endpoint to a writer.

func (*HeaderfileWriter) WriteNodeConfig

func (h *HeaderfileWriter) WriteNodeConfig(w io.Writer, cfg *datapath.LocalNodeConfiguration) error

WriteNodeConfig writes the local node configuration to the specified writer.

func (*HeaderfileWriter) WriteTemplateConfig

func (h *HeaderfileWriter) WriteTemplateConfig(w io.Writer, e datapath.EndpointConfiguration) error

WriteTemplateConfig writes the BPF configuration for the template to a writer.

type WriterParams

type WriterParams struct {
	cell.In

	Log                logrus.FieldLogger
	NodeAddressing     datapath.NodeAddressing
	NodeExtraDefines   []dpdef.Map `group:"header-node-defines"`
	NodeExtraDefineFns []dpdef.Fn  `group:"header-node-define-fns"`
	BandwidthManager   bandwidth.Manager
