const DerpMagicIP = "127.3.3.40"

DerpMagicIP is a fake WireGuard endpoint IP address that means to use DERP. When used (in the Node.DERP field), the port number of the WireGuard endpoint is the DERP region ID number to use.

Mnemonic: 3.3.40 are numbers above the keys D, E, R, P.

Functions

func CheckTag

func CheckTag(tag string) error

CheckTag validates tag for use as an ACL tag. For now we allow only ascii alphanumeric tags, and they need to start with a letter. No unicode shenanigans allowed, and we reserve punctuation marks other than '-' for a possible future URI scheme.

Because we're ignoring unicode entirely, we can treat utf-8 as a series of bytes. Anything >= 128 is disqualified anyway.

We might relax these rules later.

func Clone

func Clone(dst, src any) bool

Clone duplicates src into dst and reports whether it succeeded. To succeed, <src, dst> must be of types <*T, *T> or <*T, **T>, where T is one of User,Node,Hostinfo,NetInfo,Login,DNSConfig,RegisterResponse,RegisterResponseAuth,RegisterRequest,DERPHomeParams,DERPRegion,DERPMap,DERPNode,SSHRule,SSHAction,SSHPrincipal,ControlDialPlan,Location,UserProfile.

func UnmarshalCapJSON

func UnmarshalCapJSON[T any](cm PeerCapMap, cap PeerCapability) ([]T, error)

UnmarshalCapJSON unmarshals each JSON value in cm[cap] as T. If cap does not exist in cm, it returns (nil, nil). It returns an error if the values cannot be unmarshaled into the provided type.

func UnmarshalNodeCapJSON

func UnmarshalNodeCapJSON[T any](cm NodeCapMap, cap NodeCapability) ([]T, error)

UnmarshalNodeCapJSON unmarshals each JSON value in cm[cap] as T. If cap does not exist in cm, it returns (nil, nil). It returns an error if the values cannot be unmarshaled into the provided type.

Types

type C2NAppConnectorDomainRoutesResponse

type C2NAppConnectorDomainRoutesResponse struct {
	// Domains is a map of lower case domain names with no trailing dot,
	// to a list of resolved IP addresses.
	Domains map[string][]netip.Addr
}

C2NAppConnectorDomainRoutesResponse contains a map of domains to slice of addresses, indicating what IP addresses have been resolved for each domain.

type C2NPostureIdentityResponse

type C2NPostureIdentityResponse struct {
	// SerialNumbers is a list of serial numbers of the client machine.
	SerialNumbers []string `json:",omitempty"`

	// PostureDisabled indicates if the machine has opted out of
	// device posture collection.
	PostureDisabled bool `json:",omitempty"`
}

C2NPostureIdentityResponse contains either a set of identifying serial number from the client or a boolean indicating that the machine has opted out of posture collection.

type C2NSSHUsernamesRequest

type C2NSSHUsernamesRequest struct {
	// Exclude optionally specifies usernames to exclude
	// from the response.
	Exclude map[string]bool `json:",omitempty"`

	// Max is the maximum number of usernames to return.
	// If zero, a default limit is used.
	Max int `json:",omitempty"`
}

C2NSSHUsernamesRequest is the request for the /ssh/usernames. A GET request without a request body is equivalent to the zero value of this type. Otherwise, a POST request with a JSON-encoded request body is expected.

type C2NSSHUsernamesResponse

type C2NSSHUsernamesResponse struct {
	// Usernames is the list of usernames to suggest. If the machine has many
	// users, this list may be truncated. If getting the list of usernames might
	// be too slow or unavailable, this list might be empty. This is effectively
	// just a best effort set of hints.
	Usernames []string
}

C2NSSHUsernamesResponse is the response (from node to control) from the /ssh/usernames handler.

It returns username auto-complete suggestions for a user to SSH to this node. It's only shown to people who already have SSH access to the node. If this returns multiple usernames, only the usernames that would have access per the tailnet's ACLs are shown to the user so as to not leak the existence of usernames.

type C2NTLSCertInfo

type C2NTLSCertInfo struct {
	// Valid means that the node has a cached and valid (not expired)
	// certificate.
	Valid bool `json:",omitempty"`
	// Error is the error string if the certificate is not valid. If error is
	// non-empty, the other booleans below might say why.
	Error string `json:",omitempty"`

	// Missing is whether the error string indicates a missing certificate
	// that's never been fetched or isn't on disk.
	Missing bool `json:",omitempty"`

	// Expired is whether the error string indicates an expired certificate.
	Expired bool `json:",omitempty"`

	NotBefore string `json:",omitempty"` // RFC3339, if Valid
	NotAfter  string `json:",omitempty"` // RFC3339, if Valid

}

C2NTLSCertInfo describes the state of a cached TLS certificate.

type C2NUpdateResponse

type C2NUpdateResponse struct {
	// Err is the error message, if any.
	Err string `json:",omitempty"`

	// Enabled indicates whether the user has opted in to updates triggered from
	// control.
	Enabled bool

	// Supported indicates whether remote updates are supported on this
	// OS/platform.
	Supported bool

	// Started indicates whether the update has started.
	Started bool
}

C2NUpdateResponse is the response (from node to control) from the /update handler. It tells control the status of its request for the node to update its Tailscale installation.

type CapGrant

type CapGrant struct {
	// Dsts are the destination IP ranges that this capability
	// grant matches.
	Dsts []netip.Prefix

	// Caps are the capabilities the source IP matched by
	// FilterRule.SrcIPs are granted to the destination IP,
	// matched by Dsts.
	// Deprecated: use CapMap instead.
	Caps []PeerCapability `json:",omitempty"`

	// CapMap is a map of capabilities to their values.
	// The key is the capability name, and the value is a list of
	// values for that capability.
	CapMap PeerCapMap `json:",omitempty"`
}

CapGrant grants capabilities in a FilterRule.

type CapabilityVersion

type CapabilityVersion int

CapabilityVersion represents the client's capability level. That is, it can be thought of as the client's simple version number: a single monotonically increasing integer, rather than the relatively complex x.y.z-xxxxx semver+hash(es). Whenever the client gains a capability or wants to negotiate a change in semantics with the server (control plane), peers (over PeerAPI), or frontend (over LocalAPI), bump this number and document what's new.

Previously (prior to 2022-03-06), it was known as the "MapRequest version" or "mapVer" or "map cap" and that name and usage persists in places.

const CurrentCapabilityVersion CapabilityVersion = 87

CurrentCapabilityVersion is the current capability version of the codebase.

DERPRegion is a geographic region running DERP relay node(s).

Client nodes discover which region they're closest to, advertise that "home" DERP region (previously called "home node", when there was only 1 node per region) and maintain a persistent connection that region as long as it's the closest. Client nodes will further connect to other regions as necessary to communicate with peers advertising other regions as their homes.

EarlyNoise is the early payload that's sent over Noise but before the HTTP/2 handshake when connecting to the coordination server.

This exists to let the server push some early info to client for that stateful HTTP/2+Noise connection without incurring an extra round trip. (This would've used HTTP/2 server push, had Go's client-side APIs been available)

type Endpoint

type Endpoint struct {
	Addr netip.AddrPort
	Type EndpointType

	//
	// CapGrant and DstPorts are mutually exclusive: at most one can be non-nil.
	CapGrant []CapGrant `json:",omitempty"`
}

FilterRule represents one rule in a packet filter.

A rule is logically a set of source CIDRs to match (described by SrcIPs and SrcBits), and a set of destination targets that are then allowed if a source IP is matches of those CIDRs.

MapResponse is the response to a MapRequest. It describes the state of the local node, the peer nodes, the DNS configuration, the packet filter, and more. A MapRequest, depending on its parameters, may result in the control plane coordination server sending 0, 1 or a stream of multiple MapResponse values.

When the client sets MapRequest.Stream, the server sends a stream of MapResponses. That long-lived HTTP transaction is called a "map poll". In a map poll, the first MapResponse will be complete and subsequent MapResponses will be incremental updates with only changed information.

The zero value for all fields means "unchanged". Unfortunately, several fields were defined before that convention was established, so they use a slice with omitempty, meaning this type can't be used to marshal JSON containing non-nil zero-length slices (meaning explicitly now empty). The control plane uses a separate type to marshal these fields. This type is primarily used for unmarshaling responses so the omitempty annotations are mostly useless, except that this type is also used for the integration test's fake control server. (It's not necessary to marshal a non-nil zero-length slice for the things we've needed to test in the integration tests as of 2023-09-09).

func (*Node) Clone

func (src *Node) Clone() *Node

Clone makes a deep copy of Node. The result aliases no memory with the original.

func (*Node) DisplayName

func (n *Node) DisplayName(forOwner bool) string

DisplayName returns the user-facing name for a node which should be shown in client UIs.

Parameter forOwner specifies whether the name is requested by the owner of the node. When forOwner is false, the hostname is never included in the return value.

Return value is either "Name" or "Name (Hostname)", where Name is the node's MagicDNS base name (for normal non-shared-in nodes), FQDN (without trailing dot, for shared-in nodes), or Hostname (if no MagicDNS). Hostname is only included in the return value if it varies from Name and forOwner is provided true.

DisplayName is only valid if InitDisplayNames has been called.

func (*Node) DisplayNames

func (n *Node) DisplayNames(forOwner bool) (name, hostIfDifferent string)

DisplayName returns the decomposed user-facing name for a node.

Parameter forOwner specifies whether the name is requested by the owner of the node. When forOwner is false, hostIfDifferent is always returned empty.

Return value name is the node's primary name, populated with the node's MagicDNS base name (for normal non-shared-in nodes), FQDN (without trailing dot, for shared-in nodes), or Hostname (if no MagicDNS).

Return value hostIfDifferent, when non-empty, is the node's hostname. hostIfDifferent is only populated when the hostname varies from name and forOwner is provided as true.

DisplayNames is only valid if InitDisplayNames has been called.

type NodeCapMap map[NodeCapability][]RawMessage

NodeCapMap is a map of capabilities to their optional values. It is valid for a capability to have no values (nil slice); such capabilities can be tested for by using the Contains method.

See NodeCapability for more information on keys.

func (NodeCapMap) Contains

func (c NodeCapMap) Contains(cap NodeCapability) bool

Contains reports whether c has the capability cap. This is used to test for the existence of a capability, especially when the capability has no associated argument/data values.

func (c NodeCapMap) Equal(c2 NodeCapMap) bool

Equal reports whether c and c2 are equal.

type NodeCapability

type NodeCapability string

NodeCapability represents a capability granted to the self node as listed in MapResponse.Node.Capabilities.

It must be a URL like "https://tailscale.com/cap/file-sharing", or a well-known capability name like "funnel". The latter is only allowed for Tailscale-defined capabilities.

Unlike PeerCapability, NodeCapability is not in context of a peer and is granted to the node itself.

These are also referred to as "Node Attributes" in the ACL policy file.

}

PingRequest with no IP and Types is a request to send an HTTP request to prove the long-polling client is still connected. PingRequest with Types and IP, will send a ping to the IP and send a POST request containing a PingResponse to the URL containing results.

	// the user, and blocking allows them to immediately start
	// using the feature once enabled without rerunning the
	// command (e.g. no need to re-run "funnel on").
	//
	// The CLI can watch the IPN notification bus for changes in
