Overview

Package ipnstate captures the entire state of the Tailscale network.

It's a leaf package so ipn, wgengine, and magicsock can all depend on it.

Types

type PeerStatus 

type PeerStatus struct {

	Tags *views.Slice[string] `json:",omitempty"`

	// PrimaryRoutes are the routes this node is currently the primary
	// subnet router for, as determined by the control plane. It does
	// not include the IPs in TailscaleIPs.
	PrimaryRoutes *views.IPPrefixSlice `json:",omitempty"`

	// Endpoints:
	Addrs   []string
	CurAddr string // one of Addrs, or unique if roaming
	Relay   string // DERP region

	LastSeen       time.Time // last seen to tailcontrol; only present if offline
	LastHandshake  time.Time // with local wireguard
	Online         bool      // whether node is connected to the control plane
	KeepAlive      bool
	ExitNode       bool // true if this is the currently selected exit node.
	ExitNodeOption bool // true if this node can be an exit node (offered && approved)

	// Active is whether the node was recently active. The
	// definition is somewhat undefined but has historically and
	// currently means that there was some packet sent to this
	// peer in the past two minutes. That definition is subject to
	// change.
	Active bool

	PeerAPIURL   []string
	Capabilities []string `json:",omitempty"`

	// SSH_HostKeys are the node's SSH host keys, if known.
	SSH_HostKeys []string `json:"sshHostKeys,omitempty"`

	// ShareeNode indicates this node exists in the netmap because
	// it's owned by a shared-to user and that node might connect
	// to us. These nodes should be hidden by "tailscale status"
	// etc by default.
	ShareeNode bool `json:",omitempty"`

	// InNetworkMap means that this peer was seen in our latest network map.
	// In theory, all of InNetworkMap and InMagicSock and InEngine should all be true.
	InNetworkMap bool

	// InMagicSock means that this peer is being tracked by magicsock.
	// In theory, all of InNetworkMap and InMagicSock and InEngine should all be true.
	InMagicSock bool

	// InEngine means that this peer is tracked by the wireguard engine.
	// In theory, all of InNetworkMap and InMagicSock and InEngine should all be true.
	InEngine bool
}

type PeerStatusLite added in v1.6.0 

type PeerStatusLite struct {
	// TxBytes/RxBytes is the total number of bytes transmitted to/received from this peer.
	TxBytes, RxBytes int64
	// LastHandshake is the last time a handshake succeeded with this peer.
	// (Or we got key confirmation via the first data message,
	// which is approximately the same thing.)
	LastHandshake time.Time
	// NodeKey is this peer's public node key.
	NodeKey key.NodePublic
}

type PingResult added in v1.2.0 

type PingResult struct {
	IP       string // ping destination
	NodeIP   string // Tailscale IP of node handling IP (different for subnet routers)
	NodeName string // DNS name base or (possibly not unique) hostname

	Err            string
	LatencySeconds float64

	// Endpoint is the ip:port if direct UDP was used.
	// It is not currently set for TSMP pings.
	Endpoint string

	// DERPRegionID is non-zero DERP region ID if DERP was used.
	// It is not currently set for TSMP pings.
	DERPRegionID int

	// DERPRegionCode is the three-letter region code
	// corresponding to DERPRegionID.
	// It is not currently set for TSMP pings.
	DERPRegionCode string

	// PeerAPIPort is set by TSMP ping responses for peers that
	// are running a peerapi server. This is the port they're
	// running the server on.
	PeerAPIPort uint16 `json:",omitempty"`

	// PeerAPIURL is the URL that was hit for pings of type "peerapi" (tailcfg.PingPeerAPI).
	// It's of the form "http://ip:port" (or [ip]:port for IPv6).
	PeerAPIURL string `json:",omitempty"`

	// IsLocalIP is whether the ping request error is due to it being
	// a ping to the local node.
	IsLocalIP bool `json:",omitempty"`
}

PingResult contains response information for the "tailscale ping" subcommand, saying how Tailscale can reach a Tailscale IP or subnet-routed IP. See tailcfg.PingResponse for a related response that is sent back to control for remote diagnostic pings.

func (*PingResult) ToPingResponse added in v1.24.0 

func (pr *PingResult) ToPingResponse(pingType tailcfg.PingType) *tailcfg.PingResponse

type Status 

type Status struct {
	// Version is the daemon's long version (see version.Long).
	Version string

	// BackendState is an ipn.State string value:
	//  "NoState", "NeedsLogin", "NeedsMachineAuth", "Stopped",
	//  "Starting", "Running".
	BackendState string

	AuthURL      string       // current URL provided by control to authorize client
	TailscaleIPs []netaddr.IP // Tailscale IP(s) assigned to this node
	Self         *PeerStatus

	// Health contains health check problems.
	// Empty means everything is good. (or at least that no known
	// problems are detected)
	Health []string

	// This field is the legacy name of CurrentTailnet.MagicDNSSuffix.
	//
	// Deprecated: use CurrentTailnet.MagicDNSSuffix instead.
	MagicDNSSuffix string

	// CurrentTailnet is information about the tailnet that the node
	// is currently connected to. When not connected, this field is nil.
	CurrentTailnet *TailnetStatus

	// CertDomains are the set of DNS names for which the control
	// plane server will assist with provisioning TLS
	// certificates. See SetDNSRequest for dns-01 ACME challenges
	// for e.g. LetsEncrypt. These names are FQDNs without
	// trailing periods, and without any "_acme-challenge." prefix.
	CertDomains []string

	Peer map[key.NodePublic]*PeerStatus
	User map[tailcfg.UserID]tailcfg.UserProfile
}

Status represents the entire state of the IPN network.

func (*Status) Peers 

func (s *Status) Peers() []key.NodePublic

func (*Status) WriteHTML 

func (st *Status) WriteHTML(w io.Writer)

type StatusBuilder 

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

func (*StatusBuilder) AddPeer 

func (sb *StatusBuilder) AddPeer(peer key.NodePublic, st *PeerStatus)

AddPeer adds a peer node to the status.

Its PeerStatus is mixed with any previous status already added.

func (*StatusBuilder) AddTailscaleIP added in v1.0.0 

func (sb *StatusBuilder) AddTailscaleIP(ip netaddr.IP)

AddIP adds a Tailscale IP address to the status.

func (*StatusBuilder) AddUser 

func (sb *StatusBuilder) AddUser(id tailcfg.UserID, up tailcfg.UserProfile)

AddUser adds a user profile to the status.

func (*StatusBuilder) MutateSelfStatus added in v1.8.0 

func (sb *StatusBuilder) MutateSelfStatus(f func(*PeerStatus))

MutateSelfStatus calls f with the PeerStatus of our own node to mutate.

It may not assume other fields of status are already populated, and may not retain or write to the Status after f returns.

MutateStatus acquires a lock so f must not call back into sb.

func (*StatusBuilder) MutateStatus added in v1.8.0 

func (sb *StatusBuilder) MutateStatus(f func(*Status))

MutateStatus calls f with the status to mutate.

It may not assume other fields of status are already populated, and may not retain or write to the Status after f returns.

MutateStatus acquires a lock so f must not call back into sb.

func (*StatusBuilder) Status 

func (sb *StatusBuilder) Status() *Status

type StatusUpdater 

type StatusUpdater interface {
	UpdateStatus(*StatusBuilder)
}

type TailnetStatus added in v1.22.0 

type TailnetStatus struct {
	// Name is the name of the network that's currently in use.
	Name string

	// MagicDNSSuffix is the network's MagicDNS suffix for nodes
	// in the network such as "userfoo.tailscale.net".
	// There are no surrounding dots.
	// MagicDNSSuffix should be populated regardless of whether a domain
	// has MagicDNS enabled.
	MagicDNSSuffix string

	// MagicDNSEnabled is whether or not the network has MagicDNS enabled.
	// Note that the current device may still not support MagicDNS if
	// `--accept-dns=false` was used.
	MagicDNSEnabled bool
}

TailnetStatus is information about a Tailscale network ("tailnet").
