Types ¶
type Impl ¶
type Impl struct {
// ForwardTCPIn, if non-nil, handles forwarding an inbound TCP
// connection.
// TODO(bradfitz): provide mechanism for tsnet to reject a
// port other than accepting it and closing it.
ForwardTCPIn func(c net.Conn, port uint16)
// ProcessLocalIPs is whether netstack should handle incoming
// traffic directed at the Node.Addresses (local IPs).
// It can only be set before calling Start.
ProcessLocalIPs bool
// ProcessSubnets is whether netstack should handle incoming
// traffic destined to non-local IPs (i.e. whether it should
// be a subnet router).
// It can only be set before calling Start.
ProcessSubnets bool
// contains filtered or unexported fields
}
Impl contains the state for the netstack implementation, and implements wgengine.FakeImpl to act as a userspace network stack when Tailscale is running in fake mode.
func Create ¶ added in v1.6.0
func Create(logf logger.Logf, tundev *tstun.Wrapper, e wgengine.Engine, mc *magicsock.Conn, dialer *tsdial.Dialer, dns *dns.Manager) (*Impl, error)
Create creates and populates a new Impl.
func (*Impl) DialContextTCP ¶ added in v1.6.0
func (*Impl) DialContextUDP ¶ added in v1.10.0
func (*Impl) SetLocalBackend ¶ added in v1.20.4
func (ns *Impl) SetLocalBackend(lb *ipnlocal.LocalBackend)
SetLocalBackend sets the LocalBackend; it should only be run before the Start method is called.
