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.

Types

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 C2NUpdateResponse 

type C2NUpdateResponse struct {
	// Err is the error message, if any.
	Err string

	// 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 = 72

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 {

	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.

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.

	// ShouldWait specifies whether the CLI should block and
	// wait for the user to enable the feature.
	//
	// If this is true, the enablement from the control server
	// is expected to be a quick and uninterrupted process for

	NodeKey key.NodePublic
	// Audience the token is being requested for.
	Audience string
}

TokenRequest is a request to get an OIDC ID token for an audience. The token can be presented to any resource provider which offers OIDC Federation.

It is JSON-encoded and sent over Noise to "/machine/id-token".

type TokenResponse 

type TokenResponse struct {
	// IDToken is a JWT encoding the following standard claims:
	//
	//   `sub` | the MagicDNS name of the node
	//   `aud` | Audience from the request
	//   `exp` | Token expiry
	//   `iat` | Token issuance time
	//   `iss` | Issuer
	//   `jti` | Random token identifier
	//   `nbf` | Not before time
	//
	// It also encodes the following Tailscale specific claims:
	//
	//   `key`       | the node public key
	//   `addresses` | the Tailscale IPs of the node
	//   `nid`       | the node ID
	//   `node`      | the name of the node
	//   `domain`    | the domain of the node, it has the same format as MapResponse.Domain.
	//   `tags`      | an array of <domain:tag> on the node (like alice.github:tag:foo or example.com:tag:foo)
	//   `user`      | user emailish (like alice.github:alice@github or example.com:bob@example.com), if not tagged
	//   `uid`       | user ID, if not tagged
	IDToken string `json:"id_token"`
}

TokenResponse is the response to a TokenRequest.

type User 

type User struct {
	ID            UserID
	LoginName     string `json:"-"` // not stored, filled from Login // TODO REMOVE
	DisplayName   string // if non-empty overrides Login field
	ProfilePicURL string // if non-empty overrides Login field
	Logins        []LoginID
	Created       time.Time
}

User is an IPN user.

A user can have multiple logins associated with it (e.g. gmail and github oauth). (Note: none of our UIs support this yet.)

Some properties are inherited from the logins and can be overridden, such as display name and profile picture.

Other properties must be the same for all logins associated with a user. In particular: domain. If a user has a "tailscale.io" domain login, they cannot have a general gmail address login associated with the user.

func (*User) Clone 

func (src *User) Clone() *User

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

func (*User) View 

func (p *User) View() UserView

View returns a readonly view of User.

type UserID 

type UserID ID

func (UserID) IsZero 

func (u UserID) IsZero() bool

func (UserID) String 

func (id UserID) String() string

type UserProfile 

type UserProfile struct {
	ID            UserID
	LoginName     string // "alice@smith.com"; for display purposes only (provider is not listed)
	DisplayName   string // "Alice Smith"
	ProfilePicURL string

	// Roles exists for legacy reasons, to keep old macOS clients
	// happy. It JSON marshals as [].
	Roles emptyStructJSONSlice

	// Groups contains group identifiers for any group that this user is
	// a part of and that the coordination server is configured to tell
	// your node about. (Thus, it may be empty or incomplete.)
	// There's no semantic difference between a nil and an empty list.
	// The list is always sorted.
	Groups []string `json:",omitempty"`
}

A UserProfile is display-friendly data for a user. It includes the LoginName for display purposes but *not* the Provider. It also includes derived data from one of the user's logins.

func (*UserProfile) Clone 

func (src *UserProfile) Clone() *UserProfile

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

func (*UserProfile) Equal 

func (p *UserProfile) Equal(p2 *UserProfile) bool

func (*UserProfile) View 

func (p *UserProfile) View() UserProfileView

View returns a readonly view of UserProfile.

type UserProfileView 

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

UserProfileView provides a read-only view over UserProfile.

Its methods should only be called if `Valid()` returns true.

func (v UserProfileView) AsStruct() *UserProfile

AsStruct returns a clone of the underlying value which aliases no memory with the original.

func (UserProfileView) DisplayName 

func (v UserProfileView) DisplayName() string

func (UserProfileView) Equal 

func (v UserProfileView) Equal(v2 UserProfileView) bool

Valid reports whether underlying value is non-nil.

type UserView 

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