func (*Endpoint) MarkCTGCTime added in v0.15.7 

func (e *Endpoint) MarkCTGCTime(now time.Time)

MarkCTGCTime is the START time of a GC run. It is used by the DNS garbage collector to determine whether a DNS zombie can be deleted. This is done by comparing the timestamp of the start CT GC run with the alive timestamps of specific DNS zombies IPs marked with MarkDNSCTEntry. NOTE: While the timestamp is the start of the run, it should be set AFTER the run completes. This avoids a race between the DNS garbage collector and the CT GC. This would occur when a DNS zombie that has not been visited by the CT GC run is seen by a concurrent DNS garbage collector run, and then deleted. The DNS garbage collector is in daemon/fqdn.go and the CT GC is in pkg/maps/ctmap/gc/gc.go

func (*Endpoint) MarkDNSCTEntry added in v0.15.7 

func (e *Endpoint) MarkDNSCTEntry(dstIP netip.Addr, now time.Time)

MarkDNSCTEntry records that dstIP is in use by a connection that is allowed by toFQDNs policy. The reverse lookup is attempted in both DNSHistory and DNSCTHistory, allowing short DNS TTLs but long-lived connections to persist there.DNSCTHistory is used to suppress delete handling of expired DNS lookups (in DNSHistory) and it relies on pkg/maps/ctmap/gc to call this function. Internally, the lookupTime is used to checkpoint this update so that dns-garbage-collector-job can correctly clear older connection data.

func (*Endpoint) MarshalJSON added in v0.15.7 

func (ep *Endpoint) MarshalJSON() ([]byte, error)

MarshalJSON marshals the Endpoint as its serializableEndpoint representation.

func (*Endpoint) ModifyIdentityLabels added in v0.15.7 

func (e *Endpoint) ModifyIdentityLabels(source string, addLabels, delLabels labels.Labels) error

ModifyIdentityLabels changes the custom and orchestration identity labels of an endpoint. Labels can be added or deleted. If a label change is performed, the endpoint will receive a new identity and will be regenerated. Both of these operations will happen in the background.

func (e *Endpoint) PolicyRevisionBumpEvent(rev uint64)

PolicyRevisionBumpEvent queues an event for the given endpoint to set its realized policy revision to rev. This may block depending on if events have been queued up for the given endpoint. It blocks until the event has succeeded, or if the event has been cancelled.

func (*Endpoint) ProcessChangeRequest added in v0.15.7 

func (e *Endpoint) ProcessChangeRequest(newEp *Endpoint, validPatchTransitionState bool) (string, error)

ProcessChangeRequest handles the update logic for performing a PATCH operation on a given Endpoint. Returns the reason which will be used for informational purposes should a caller choose to try to regenerate this endpoint, as well as an error if the Endpoint is being deleted, since there is no point in changing an Endpoint if it is going to be deleted.

Before adding any new fields here, check to see if they are assumed to be mutable after endpoint creation!

func (*Endpoint) Regenerate 

func (e *Endpoint) Regenerate(regenMetadata *regeneration.ExternalRegenerationMetadata) <-chan bool

Regenerate forces the regeneration of endpoint programs & policy Should only be called with e.state at StateWaitingToRegenerate, StateWaitingForIdentity, or StateRestoring

func (e *Endpoint) RunMetadataResolver(restoredEndpoint, blocking bool, baseLabels labels.Labels, bwm bandwidth.Manager, resolveMetadata MetadataResolverCB) (regenTriggered bool)

RunMetadataResolver starts a controller associated with the received endpoint which will periodically attempt to resolve the metadata for the endpoint and update the endpoint with the related. It stops resolving after either the first successful metadata resolution or when the endpoint is removed.

baseLabels contains the list of labels use as "base" for the endpoint. The labels retrieved from 'MetadataResolverCB' will be merged into the baseLabels and put into the endpoint. If this list is empty, the labels set on the endpoint will be replaced by the labels returned 'MetadataResolverCB' as long their source matches the source of the labels already present on the endpoint.

restoredEndpoint should be set to 'true' if the endpoint is being restored. If this is set to false and the resolver is unable to retrieve the endpoint labels from k8s, the endpoint will be set with the 'init' identity.

blocking - will block this function until the endpoint receives a new security identity, and it is regenerated. If 'false', this operation will be done in the background and 'regenTriggered' will always be 'false'.

This assumes that after the initial successful resolution, other mechanisms will handle updates (such as pkg/k8s/watchers informers).

UpdateLabels is called to update the labels of an endpoint for the given 'sourceFilter', if 'source' is 'LabelSourceAny' then all labels are replaced. Calls to this function do not necessarily mean that the labels actually changed. The container runtime layer will periodically synchronize labels.

The specified 'sourceFilter' will only remove the labels with that same source. For example: If the endpoint contains `k8s:foo=bar` and if 'sourceFilter' is 'cni' with labels `cni:bar=bar`, the result is: 

`k8s:foo=bar` + `cni:bar=bar` - The "foo=bar" label is kept.

if 'sourceFilter' is 'any' with labels `cni:bar=bar`, the result is: 

`cni:bar=bar` - The "foo=bar" gets removed.

If a net label changed was performed, the endpoint will receive a new security identity and will be regenerated. Both of these operations will run first synchronously if 'blocking' is true, and then in the background.

Returns 'true' if endpoint regeneration was triggered.
