Types

type Client

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

Client is a flow update client

func NewClient

func NewClient(ctx context.Context) (*Client, error)

NewClient creates a new flow tracking client. s

func (*Client) Close

func (c *Client) Close() error

Close will close the connection of the client.

func (*Client) UpdateApplicationFlowMark

func (c *Client) UpdateApplicationFlowMark(ipSrc, ipDst net.IP, protonum uint8, srcport, dstport uint16, newmark uint32) error

UpdateApplicationFlowMark will update the mark for a flow based on the packet information received from an application. It will use the forward entries of conntrack for that.

func (*Client) UpdateMark

func (c *Client) UpdateMark(ipSrc, ipDst net.IP, protonum uint8, srcport, dstport uint16, newmark uint32, network bool) error

UpdateMark updates the mark of the flow. Caller must indicate if this is an application flow or a network flow.

func (*Client) UpdateNetworkFlowMark

func (c *Client) UpdateNetworkFlowMark(ipSrc, ipDst net.IP, protonum uint8, srcport, dstport uint16, newmark uint32) error

UpdateNetworkFlowMark will update the mark for a flow based on packet information received from the network. It will use the reverse tables in conntrack for that.
