package macaddr

v5.3.0 (2022-03-04)

• Add with_port_of_string function (@dinosaure, @hannesm, #108)

• breaking-change Be restrictive on Ipaddr.of_string (@dinosaure, @hannesm, #109) Before this release, Ipaddr.of_string accepts remaining bytes and returns a valid value such as "127.0.0.1aaaa" is valid. Now, ipaddr does not accept a string with remaining bytes.

v5.2.0 (2021-09-11)

• Use Cstruct.length instead of deprecated Cstruct.len (#106, @hannesm)

• Provide instantiated functors Set, Map, V4.Set, V4.Map, V6.Set, V6.Map (#106, @hannesm)

v5.1.0 (2021-06-08)

• Reject octal notation in IPv4 (cve-2021-29921, #104, @jsachs)

• CI fixes, upgrade to ocamlformat 0.18 (@hannesm)

v5.0.1 (2020-09-30)

• Fix V4.Prefix.broadcast and last with /32 prefixes (#102 @verbosemode)

v5.0.0 (2020-06-16)

• Do not zero out the non-prefix-length part of the address in {V4,V6}.Prefix.t (#99 @hannesm) Removed {V4,V6}.Prefix.of_address_string{,_exn} and {V4,V6}.Prefix.to_address_{string.buffer}

  To port code:

  • if you rely on Prefix.of_string to zero out the non-prefix-length address bits, call Prefix.prefix : t -> t subsequently.

  • Prefix.of_address_string{,_exn} can be replaced by Prefix.of_string{,_exn}, to retrieve the address use Prefix.address : t -> addr.

  • The Prefix.to_address_{string,buffer} can be replaced by Prefix.to_{string,buffer}, where Prefix.t already contains the IP address to be printed.

  • Instead of passing {V4,V6}.t * {V4,V6}.Prefix.t for an address and subnet configuration, {V4,V6}.Prefix.t is sufficient.

• Implement {V4,V6,}.succ, {V4,V6,}.pred, {V4,V6}.Prefix.first, and {V4,V6}.Prefix.last functions (#94 @NightBlues)

• Rename Prefix.of_netmask to Prefix.of_netmask_exn with labelled arguments (~netmask and ~address), provide Prefix.of_netmask which returns a (t, [> `Msg of string ]) result value (#95 @hannesm)

• Fix undefined behaviour of V4.Prefix.mem with a CIDR with prefix length 0 (#98 @verbosemode)

• Use stdlib-shims to prevent deprecation warnings on OCaml 4.08 (@avsm)

• Remove unnecessary "sexplib0" dependency (#95 @hannesm)

• Remove "{build}" directive from "dune" dependency (#93 @CraigFe)

v4.0.0 (2019-07-12)

• Rename the to/from_bytes functions to refer to octets instead. This distinguishes the meaning of human-readable addresses (strings in this library) and byte-packed representations(octets in this library) from the OCaml bytes type that represents mutable strings.

  Porting code should just be a matter of renaming functions such as:

  • Ipaddr.of_bytes becomes Ipaddr.of_octets

  • Macaddr.to_bytes becomes Macaddr.to_octets

• Introduce new write_octets functions that can write octet representations of IPv4/v6 into an existing bytestring.

• Use the domain-name library to produce domain names from IP addresses.

• Remove the ipaddr.sexp and macaddr.sexp ocamlfind subpackages and instead have ipaddr-sexp and macaddr-sexp to match the opam package names.

• Add new Ipaddr_cstruct and Macaddr_cstruct libraries for conversion to/from cstructs (#36 @nojb @avsm)

v3.1.0 (2019-03-02)

• Do not leak a Not_found exception when parsing [: in IPv6 and instead raise Parse_error as other errors do (found by fuzz testing in #84 by @dinosaure)

• Install automatic toplevel printers for the Ipaddr types via [@@ocaml.toplevel_printer]. This enables utop to automatically install the printers (@avsm)

3.0.0 (2019-01-02)

This release features several backwards incompatible changes, but ones that should increase the portability and robustness of the library.

• Remove the sexp serialisers from the main interface in favour of pp functions. Use the Ipaddr_sexp module if you still need a sexp serialiser.

  To use these with ppx-based derivers, simply replace the reference to the Ipaddr type definition with Ipaddr_sexp. That will import the sexp-conversion functions, and the actual type definitions are simply aliases to the corresponding type within Ipaddr. For example, you might do:

  type t = {
    ip: Ipaddr_sexp.t;
    mac: Macaddr_sexp.t;
  } [@@deriving sexp]
  

  The actual types of the records will be aliases to the main library types, and there will be two new functions available as converters. The signature after ppx has run will be:

  type t = {
    ip: Ipaddr.t;
    mac: Macaddr.t;
  }
  val sexp_of_t : t -> Sexplib0.t
  val t_of_sexp : Sexplib0.t -> t
  

• Break out the Macaddr module into a separate opam package so that the Ipaddr module can be wrapped. Use the macaddr opam library now if you need just the MAC address functionality.

• Replace all the of_string/bytes functions that formerly returned option types with the Rresult result types instead. This stops the cause of the exception from being swallowed, and the error message in the new functions can be displayed usefully.

• In the Ipaddr.V6.to_string and to_buffer functions, remove the optional labelled argument v4 and always output v4-mapped strings as recommended by RFC5952. (#80 by @hannesm).

• Remove pp_hum which was deprecated in 2.9.0.

• Sexplib0 is now used which is more lightweight tha the full Sexplib library. Minimum OCaml version is now 4.04.0+ as a result of this dependency.

• Improvements to the ocamldoc formatting strings for better layout and odoc compatibility.

2.9.0 (2018-12-11)

• Add pp functions for prettyprinting and deprecate pp_hum variants. The two functions are currently the same, so porting is just a matter of replacing existing uses of pp_hum with pp (#71 @verbosemode)

• Fix deprecation warnings on newer OCaml standard libraries (#74 @cfcs).

• Fix base-unix depopt to be a real dependency (#68 @rgrinberg).

• Fix missing sexplib dependency (#66 #67 @bmillwood).

• Port to Dune from jbuilder and update opam metadata to 2.0 format (#76 @avsm).

• Remove unused variable and bindings warnings in the implementation and signatures (#76 @avsm)

• Fix toplevel handling of the ipaddr.top package by linking to compiler-libs instead of compiler-libs.toplevel (#76 @avsm based on fix in mirage/ocaml-uri#130 by @yallop)

• Update Travis to test latest distros by using their aliases (#76 @avsm)

• Upgrade opam metadata to the 2.0 format (#76 @avsm)

2.8.0 (2017-06-01)

• Port to Jbuilder (#65 @vbmithr @avsm). There should be no observable changes, except that Ipaddr_unix is now in a separate subdirectory. This means that packages that implicitly depended on the module without including the ocamlfind ipaddr.unix package may now fail. Just adding the ocamlfind dependency will fix it, and is backwards compatible with older Ipaddr releases.

• Minimum version of OCaml required is now 4.03.0 (formerly was 4.02.2), due to the use of recent ppx_sexp_conv with Jbuilder also having that as the minimum supported compiler version.

2.7.2 (2017-02-16)
