Types ¶
type CompileTimeConfig ¶
type CompileTimeConfig interface {
DeviceConfig
// RequireEgressProg returns true if the endpoint requires an egress
// program attached to the InterfaceName() invoking the section
// "to-container"
RequireEgressProg() bool
// RequireRouting returns true if the endpoint requires BPF routing to
// be enabled, when disabled, routing is delegated to Linux routing
RequireRouting() bool
// RequireEndpointRoute returns true if the endpoint wishes to have a
// per endpoint route installed in the host's routing table to point to
// the endpoint's interface
RequireEndpointRoute() bool
// IsHost returns true if the endpoint is the host endpoint.
IsHost() bool
}
CompileTimeConfig provides datapath implementations a clean interface to access endpoint-specific configuration that can only be changed at compile time.
type Config ¶
type Config interface {
CompileTimeConfig
LoadTimeConfig
}
Config provides datapath implementations a clean interface to access endpoint-specific configuration when configuring the datapath.
type DeviceConfig ¶
type DeviceConfig interface {
// GetOptions fetches the configurable datapath options from the owner.
GetOptions() *option.IntOptions
}
DeviceConfig is an interface for injecting configuration of datapath options that affect lookups and logic applied at a per-device level, whether those are devices associated with the endpoint or associated with the host.
type Endpoint ¶
type Endpoint interface {
Config
InterfaceName() string
Logger(subsystem string) *slog.Logger
StateDir() string
}
Endpoint provides access endpoint configuration information that is necessary to compile and load the datapath.
type LoadTimeConfig ¶
type LoadTimeConfig interface {
// GetID returns a locally-significant endpoint identification number.
GetID() uint64
// StringID returns the string-formatted version of the ID from GetID().
StringID() string
// GetIdentity returns a globally-significant numeric security identity.
GetIdentity() identity.NumericIdentity
IPv4Address() netip.Addr
IPv6Address() netip.Addr
GetNodeMAC() mac.MAC
GetIfIndex() int
GetEndpointNetNsCookie() uint64
// GetPolicyVerdictLogFilter returns the PolicyVerdictLogFilter for the endpoint
GetPolicyVerdictLogFilter() uint32
// GetPropertyValue returns the endpoint property value for this key.
GetPropertyValue(key string) any
// GetRTInfo returns the routing domain info for the pod and its encoding.
GetRTInfo() (uint32, RTInfoEncoding)
// RequireARPPassthrough returns true if the datapath must implement
// ARP passthrough for this endpoint
RequireARPPassthrough() bool
}
LoadTimeConfig provides datapath implementations a clean interface to access endpoint-specific configuration that can be changed at load time.
type Orchestrator ¶
type Orchestrator interface {
Reinitialize(ctx context.Context) error
DatapathInitialized() <-chan struct{}
ReloadDatapath(ctx context.Context, ep Endpoint, stats *metrics.SpanStat) (string, error)
EndpointHash(cfg Config) (string, error)
WriteEndpointConfig(w io.Writer, cfg Config) error
Unload(ep Endpoint)
}
type RTInfoEncoding ¶
type RTInfoEncoding string
RTInfoEncoding describes a possible encoding of the RTInfo field of an endpoint.
const ( RTInfoNone RTInfoEncoding = "" RTInfoFIB RTInfoEncoding = "fib" )
