v3.6.0

CHANGES:

• The IPv4 implementation now supports reassembly of IPv4 fragments (#375 by @hannesm)

  • using a LRU cache using up to 256KB memory
  • out of order fragments are supported
  • maximum number of fragments is 16
  • timeout between first and last fragment is 10s
  • overlapping fragments are dropped

• IPv6: use correct timeout value after first NS message (#334 @djs55)

• Use Ipaddr.pp instead of Ipaddr.pp_hum due to upstream
  interface changes (#385 @hannesm).

v3.5.1

CHANGES:

• socket stack (tcp/udp): catch exception in recv_from and accept (#376 @hannesm)
• use mirage-random-test for testing (Stdlibrandom got removed from mirage-random>1.2.0, #377 @hannesm)

v3.5.0

v3.5.0 (2018-09-16)

• Ipv4: require Mirage_random.C, used for generating IPv4 identifier instead of using OCaml's stdlib Random directly (#371 @hannesm)
• Tcp: use entire 32 bits at random for the initial sequence number, thanks to Spencer Michaels and Jeff Dileo of NCC Group for reporting (#371 @hannesm)
• adjust to mirage-protocols 1.4.0 and mirage-stack 1.3.0 changes (#371 @hannesm)
  Arp no longer contains the type alias ethif
  Ethif no longer contains the type alias netif
  Static_ipv4 no longer contains the type alias ethif and prefix
  Ipv6 no longer contains the type alias ethif and prefix
  Mirage_protocols_lwt.IPV4 no longer contains the type alias ethif
  Mirage_protocols_lwt.UDPV4 and TCPV4 no longer contain the type alias ip
• remove unused types: 'a config, netif, and id from socket and direct stack (#371 @hannesm)
• remove usage of Result, depending on OCaml >= 4.03.0 (#372 @hannesm)

v3.4.2

Note the use of the new TCP keep-alive feature can cause excessive amounts
of memory to be used in some circumstances, see
#367

• Ensure a zero UDP checksum is sent as 0xffff, not 0x0000 (#359 @stedolan)
• Avoid leaking a file descriptor in the socket stack if the connection fails (#363 @hannesm)
• Avoid raising an exception with Lwt.fail when write fails in the socket stack (#363 @hannesm)
• Ignore EBADF errors in close in the socket stack (#366 @hannesm)
• Emit a warning when TCP keep-alives are used (#368 @djs55)

tcp_socket_options fix

• expose tcp_socket_options in the socket stack, fixing downstream builds (#356 @yomimono)
• add missing dependencies and constraints (#354 @yomimono, #353 @rgrinberg)
• remove leftover ocamlbuild files (#353 @rgrinberg)

TCP improvements

• Add support for TCP keepalives (#338 @djs55)
• Fix TCP deadlock (#343 @mfp)
• Update the CI to test OCaml 4.04, 4.05, 4.06 (#344 @yomimono)

v3.3.1

• Add an example for user-space ping, and some socket ICMPv4 fixes (#336 @djs55)
• Make tcpip safe-string-safe (and buildable by default on OCaml 4.06.0) (#341 @djs55)

v3.3.0

v3.3.0 (2017-08-08)

• Test with current mirage-www master (#323 @yomimono)
• Improve the Tcp.Wire API (#325 @samoht)
• Add dependency from stack-unix to io-page-unix (@avsm)
• Replace dependency on cstruct.lwt with cstruct-lwt (#322 @yomimono)
• Update to lwt 3.0 (#326 @samoht)
• Replace oUnit with alcotest (#329 @samoht)
• Fix stub linking on Xen (#332 @djs55)
• Add support for ICMP sockets on Windows (#333 @djs55)

port to Jbuilder

Port to jbuilder. Build time is now roughly 4-5x faster than the old oasis-based build system. Packs have been replaced with module aliases.

Avoid linking PPX into the generated binaries

• avoid linking to cstruct.ppx in the compiled library and only use it at build time (#316 @djs55)
• use improved packet size support in mirage-vnetif>=0.4.0 to test the MTU fixes in #313.
