Types

type DatapathRegenerationLevel

type DatapathRegenerationLevel int

DatapathRegenerationLevel determines what is expected of the datapath when a regeneration event is processed.

const (
	// Invalid is the default level to enforce explicit setting of
	// the regeneration level.
	Invalid DatapathRegenerationLevel = iota
	// RegenerateWithoutDatapath indicates that datapath rebuild or reload
	// is not required to implement this regeneration.
	RegenerateWithoutDatapath
	// RegenerateWithDatapath indicates that the datapath must be
	// recompiled and reloaded to implement this regeneration.
	RegenerateWithDatapath
)

func (DatapathRegenerationLevel) String

func (r DatapathRegenerationLevel) String() string

String converts a DatapathRegenerationLevel into a human-readable string.

type ExternalRegenerationMetadata

type ExternalRegenerationMetadata struct {
	// Reason provides context to source for the regeneration, which is
	// used to generate useful log messages.
	Reason string

	// RegenerationLevel forces datapath regeneration according to the
	// levels defined in the DatapathRegenerationLevel description.
	RegenerationLevel DatapathRegenerationLevel

	ParentContext context.Context
}

ExternalRegenerationMetadata contains any information about a regeneration that the endpoint subsystem should be made aware of for a given endpoint.

type Owner

type Owner interface {
	// QueueEndpointBuild puts the given endpoint in the processing queue
	QueueEndpointBuild(ctx context.Context, epID uint64) (func(), error)

	// GetCompilationLock returns the mutex responsible for synchronizing compilation
	// of BPF programs.
	GetCompilationLock() datapath.CompilationLock

	// SendNotification is called to emit an agent notification
	SendNotification(msg monitorAPI.AgentNotifyMessage) error

	// Loader returns a reference to the loader implementation.
	Loader() datapath.Loader

	Orchestrator() datapath.Orchestrator

	BandwidthManager() datapath.BandwidthManager

	IPTablesManager() datapath.IptablesManager

	// GetDNSRules creates a fresh copy of DNS rules that can be used when
	// endpoint is restored on a restart.
	// The endpoint lock must not be held while calling this function.
	GetDNSRules(epID uint16) restore.DNSRules

	// RemoveRestoredDNSRules removes any restored DNS rules for
	// this endpoint from the DNS proxy.
	RemoveRestoredDNSRules(epID uint16)

	AddIdentity(*identity.Identity)
	RemoveIdentity(*identity.Identity)
	RemoveOldAddNewIdentity(*identity.Identity, *identity.Identity)
}

Owner is the interface defines the requirements for anybody owning policies.
