Types

type NetworkMap

type NetworkMap struct {
	SelfNode   *tailcfg.Node
	NodeKey    key.NodePublic
	PrivateKey key.NodePrivate
	Expiry     time.Time
	// Name is the DNS name assigned to this node.
	Name          string
	Addresses     []netaddr.IPPrefix // same as tailcfg.Node.Addresses (IP addresses of this Node directly)
	LocalPort     uint16             // used for debugging
	MachineStatus tailcfg.MachineStatus
	MachineKey    key.MachinePublic
	Peers         []*tailcfg.Node // sorted by Node.ID
	DNS           tailcfg.DNSConfig
	// TODO(maisem) : replace with View.
	Hostinfo     tailcfg.Hostinfo
	PacketFilter []filter.Match
	SSHPolicy    *tailcfg.SSHPolicy // or nil, if not enabled/allowed

	// CollectServices reports whether this node's Tailnet has
	// requested that info about services be included in HostInfo.
	// If set, Hostinfo.ShieldsUp blocks services collection; that
	// takes precedence over this field.
	CollectServices bool

	// DERPMap is the last DERP server map received. It's reused
	// between updates and should not be modified.
	DERPMap *tailcfg.DERPMap

	// Debug knobs from control server for debug or feature gating.
	Debug *tailcfg.Debug

	// ControlHealth are the list of health check problems for this
	// node from the perspective of the control plane.
	// If empty, there are no known problems from the control plane's
	// point of view, but the node might know about its own health
	// check problems.
	ControlHealth []string

	User tailcfg.UserID

	// Domain is the current Tailnet name.
	Domain string

	UserProfiles map[tailcfg.UserID]tailcfg.UserProfile
}

NetworkMap is the current state of the world.

The fields should all be considered read-only. They might alias parts of previous NetworkMap values.

func (*NetworkMap) Concise

func (nm *NetworkMap) Concise() string

func (*NetworkMap) ConciseDiffFrom

func (b *NetworkMap) ConciseDiffFrom(a *NetworkMap) string

func (*NetworkMap) JSON

func (nm *NetworkMap) JSON() string

func (*NetworkMap) MagicDNSSuffix

func (nm *NetworkMap) MagicDNSSuffix() string

MagicDNSSuffix returns the domain's MagicDNS suffix (even if MagicDNS isn't necessarily in use).

It will neither start nor end with a period.

func (*NetworkMap) VeryConcise

func (nm *NetworkMap) VeryConcise() string

type WGConfigFlags

type WGConfigFlags int

WGConfigFlags is a bitmask of flags to control the behavior of the wireguard configuration generation done by NetMap.WGCfg.

const (
	AllowSingleHosts WGConfigFlags = 1 << iota
	AllowSubnetRoutes
)
