6.4.0

CHANGES:

• Adapt to mirage-protocols 6.0.0 API (#457 @hannesm)
• TCP and UDP now have a listen and unlisten function (fixes #452)
• type ipinput (in TCP and UDP) and listener (in TCP) have been removed

6.3.0

CHANGES:

• Use Cstruct.length instead of deprecated Cstruct.len (#454 @hannesm)
• Avoid deprecated Fmt functions (#455 @hannesm)
• Remove rresult dependency (#455 @hannesm)
• Require OCaml 4.08
• Record TCP statistics via metrics library (#455 @hannesm)

v6.2.0

CHANGES:

• This allows to listen on the same port as sending via UDP in the dual socket
  stack, and avoids file descriptor leaks in the socket stack.
• Socket stack: avoid file descriptor leaks (remember opened file descriptors in
  data structure, close them in disconnect)
  (#449 @reynir @hannesm, fixes #446 #450)
• Socket stack: convert an incoming packet on a dual socket to v4 source IP if
  received via IPv4 (#451 @reynir @hannesm)
• Allow freestanding compilation without opam (#447 @sternenseemann)
• Adapt to alcotest 1.4.0 breaking change (#448 @craigfe)

v6.1.0

CHANGES:

• checksum stubs: Drop caml_ from their name (@hannesm, #445)
• Add cancelation on tcpip.stack-socket (@dinosaure, @talex5, @hannesm, #443)
• Ensure that listen really binds the given socket before
  creating a task on tcpip.stack-socket (@dinosaure, @hannesm, #439)
• Add ppx_cstruct as a dependency (@hannesm, @dinosaure, #439)
• Upgrade to ocamlformat.0.17.0 (@dinosaure, #442)
• Drop the support of OCaml 4.08.0 (@dinosaure, #442)
• Use the usual layout to compile freestanding C stubs and link them to
  a Solo5 unikernel (@dinosaure, @hannesm, #441)
  breaking changes
  C stubs are prepended by mirage_. Symbols such as checksum's
  symbols are caml_mirage_tcpip_* instead of caml_tcpip_*
tcpip.unix is a fake sub-package and user does not it anymore, he can
  safely remove it from its project.
• Conflict with < ocaml-freestanding.0.4.1 (@hannesm, #441)

v6.0.0

CHANGES:

• Dual IPv4 and IPv6 socket and direct stack support, now requires
  mirage-stack 2.2.0 and mirage-protocols 5.0.0 (#433 @hannesm)
• The above change also unified arguments passed to connect functions which
  are API-breaking changes
• IPv6 waits for timeout after sending neighbour advertisement (for duplicate
  address detection)
• Remove Xen cross-compilation runes, with mirage-xen 6.0.0 they're provided
  by mirage-xen (#434 @hannesm)
• Move to dune 2.7.0 (and bisect instrumentation if desired) (#436 @hannesm)

v5.0.1

CHANGES:

• Assorted IPv6 improvements (#428 #431 #432 @MagnusS @hannesm)
  • set length in packets to be sent
  • preserve updated ctx from Ndv6.handle
  • fix ICMP checksum computation
  • implement Mirage_stack.V6 signature
  • add connect, mtu, iperf tests
  • fix DAD protocol implementation (and test it)
  • avoid out of bounds accesses of IPv6 packets (check length before accessing)
• Fix 32 bit issues (@MagnusS)
• Implement stack-direct and tcp disconnect: tear down existing connections (#429 @hannesm)
• Treat broadcast address of network as broadcast as well (#430 @hannesm, reported in #427)

v5.0.0

CHANGES:

• Static_ipv4.connect API change: takes a cidr:Ipaddr.V4.Prefix.t instead of
  ip:Ipaddr.V4.t and network:Ipaddr.V4.Prefix.t (#426 @hannesm)
• Adapt to ipaddr 5.0.0 API changes (#426 @hannesm)

v4.1.0

CHANGES:

• Revert "Ipv4.Fragments use a Lru.M.t instead of Lru.F.t" (#423 by @hannesm)
  A Lru.M.t allocates a Hashtbl.t of size = capacity (= 256 * 1024 in our case),
  this leads to excessive ~2MB memory consumption for each Fragment cache,
  reported by @xaki23 in mirage/qubes-mirage-firewall#93
• use SOCK_RAW for an ICMP socket in the unix sockets API (previously used
  SOCK_DGRAM which did not work)
  reported by @justinc1 in #358, fixed in #424 by @hannesm
• tcp is now compatible with lwt >= 5.0.0 (where Lwt.async requires a function
  of (unit -> unit Lwt.t) (#370 #425 @cfcs @hannesm, issue #392 @emillon)
• Add a dependency on dune-configurator to support dune 2.0.0 (#421 @avsm)

v4.0.0

CHANGES:

• Adapt to mirage-protocols 4.0.0, mirage-net 3.0.0, mirage-time 2.0.0,
  mirage-clock 3.0.0, mirage-stack 2.0.0 interface changes (#420 @hannesm)
• Revise Static_ipv4.connect signature (for more safety):
  val connect : ip:(Ipaddr.V4.Prefix.t * Ipaddr.V4.t) -> ?gateway:Ipaddr.V4.t ->
  ?fragment_cache_size:int -> E.t -> A.t -> t Lwt.t
  it used to be:
  val connect : ?ip:Ipaddr.V4.t -> ?network:Ipaddr.V4.Prefix.t ->
  ?gateway:Ipaddr.V4.t option -> C.t -> E.t -> A.t -> t Lwt.t
  The clock C.t is gone (due to mirage-clock 3.0.0), ~ip and ~network are
  now required and passed as pair ~ip. The optional argument ?gateway is
  of type Ipaddr.V4.t. The new optional labeled argument ~fragment_cache_size
  specifies the byte size of the IPv4 fragment cache (#420 @hannesm)

v3.7.9

CHANGES:

• Add ?ttl:int parameter to Udp and Icmp write (#416 @phaer)
• Ipv4.Fragments use a Lru.M.t instead of Lru.F.t (#418 @hannesm)
• Adapt to mirage-protocols 3.1.0 changes (#419 @hannesm)
  • removed IP.set_ip
  • added `Would_fragment to Ip.error
