Tcpip_stack_direct.MakeV6 · tcpip 5.0.1

Parameters

module Time : Mirage_time.S

module Random : Mirage_random.S

module Netif : Mirage_net.S

module Ethernet : Mirage_protocols.ETHERNET

module Ipv6 : Mirage_protocols.IP with type ipaddr = Ipaddr.V6.t

module Udpv6 : UDPV6_DIRECT

module Tcpv6 : TCPV6_DIRECT

Signature

include Mirage_stack.V6
  with module IP = Ipv6
   and module TCP = Tcpv6
   and module UDP = Udpv6

type t

The type representing the internal state of the IPv6 stack.

val disconnect : t -> unit Lwt.t

Disconnect from the IPv6 stack. While this might take some time to complete, it can never result in an error.

module UDP = Udpv6

module TCP = Tcpv6

module IP = Ipv6

val udp : t -> UDP.t

udp t obtains a descriptor for use with the UDPV6 module, usually to transmit traffic.

val tcp : t -> TCP.t

tcp t obtains a descriptor for use with the TCPV6 module, usually to initiate outgoing connections.

val ip : t -> IP.t

ip t obtains a descriptor for use with the IPV6 module, which can handle raw IPv6 frames, or manipulate IP address configuration on the stack interface.

val listen_udp : t -> port:int -> UDP.callback -> unit

listen_udp t ~port cb registers the cb callback on the UDPv6 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash.

val listen_tcp : 
  ?keepalive:Mirage_protocols.Keepalive.t ->
  t ->
  port:int ->
  ( TCP.flow -> unit Lwt.t ) ->
  unit

listen_tcp ~keepalive t ~port cb registers the cb callback on the TCPv6 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash. If ~keepalive is provided then these keepalive settings will be applied to the accepted connections before the callback is called.

val listen : t -> unit Lwt.t

listen t requests that the stack listen for traffic on the network interface associated with the stack, and demultiplex traffic to the appropriate callbacks.

val connect : Netif.t -> Ethernet.t -> Ipv6.t -> Udpv6.t -> Tcpv6.t -> t Lwt.t

connect assembles the arguments into a network stack, then calls `listen` on the assembled stack before returning it to the caller. The initial `listen` functions to ensure that the lower-level layers are functioning, so that if the user wishes to establish outbound connections, they will be able to do so.
