3.3.0 (2018-11-18)

New target: (via solo5) Genode: "Genode is a free and open-source operating system framework consisting of a microkernel abstraction layer and a collection of userspace components. The framework is notable as one of the few open-source operating systems not derived from a proprietary OS, such as Unix. The characteristic design philosophy is that a small trusted computing base is of primary concern in a security oriented OS." (from wikipedia, more at https://genode.org/ #942, by @ehmry)

User-visible changes

• use mirage-bootvar-unix instead of OS.Env.argv (deprecated since mirage-{xen,unix,os-shim}.3.1.0, mirage-solo5.0.5.0) on unix (#931, by @hannesm)

  WARNING: this leads to a different semantics for argument passing on Unix: all arguments are concatenated (using a whitespace " " as separator), and split on the whitespace character again (by parse-argv). This is coherent with all other backends, but the whitespace in "--hello=foo bar" needs to be escaped now.

• mirage now generates upper bounds for hard-coded packages that are used in generated code. When we now break the API, unikernels which are configured with an earlier version won't accept the new release of the dependency. This means API breakage is much smoother for us, apart from that we now track version numbers in the mirage utility. The following rules were applied for upper bounds:

  • if version < 1.0.0 then ~min:"a.b.c" ~max:"a.(b+1).0"

  • if version > 1.0.0 then ~min:"a.b.c" ~max:"(a+1).0.0"`

  • exceptions: tcpip (~min:"3.5.0" ~max:"3.6.0"), mirage-block-ramdisk (unconstrained)

  WARNING: Please be careful when release any of the referenced libraries by taking care of appropriate version numbering. (initial version in #855 by @avsm, final #946 by @hannesm)

• since functoria.2.2.2, the "package" function (used in unikernel configuration) is extended with the labeled argument ~pin that receives a string (e.g. ~pin:"git+https://github.com/mirage-random/mirage-random.git"), and is embedded into the generated opam file as pin-depends

• mirage-random-stdlib is now used for default_random instead of mirage-random (which since 1.2.0 no longer bundles the stdlib Random module). mirage-random-stdlib is not cryptographically secure, but "a lagged-Fibonacci F(55, 24, +) with a modified addition function to enhance the mixing of bits.", which is now seeded using mirage-entropy. If you configure your unikernel with "mirage configure --prng fortuna" (since mirage 3.0.0), a cryptographically secure PRNG will be used (read more at https://mirage.io/blog/mirage-entropy)

• mirage now revived its command-line "--no-depext", which removes the call to "opam depext" in the depend and depends target of the generated Makefile (#948, by @hannesm)

• make depend no longer uses opam pin for opam install --deps-only (#948, by @hannesm)

• remove unused io_page configuration (initial discussion in #855, #940, by @hannesm)

• charrua-client requires a Mirage_random interface since 0.11.0 (#938, by @hannesm)

• split implementations into separate modules (#933, by @emillon)

• improved opam2 support (declare ocaml as dependency #926)

• switch build system to dune (#927, by @emillon)

• block device writes has been fixed in mirage-solo5.0.5.0

3.2.0 (2018-09-23)

• adapt to solo5 0.4.0 changes (#924, by @mato) Upgrading from Mirage 3.1.x or earlier

Due to conflicting packages, opam will not upgrade mirage to version 3.2.0 or newer if a version of mirage-solo5 older than 0.4.0 is installed in the switch. To perform the upgrade you must run opam upgrade mirage explicitly.

Changes required to rebuild and run ukvm unikernels

As of Solo5 0.4.0, the ukvm target has been renamed to hvt. If you are working out of an existing, dirty, source tree, you should initially run:

mirage configure -t hvt
mirage clean
mirage configure -t hvt

and then proceed as normal. If you are working with a clean source tree, then simply configuring with the new hvt target is sufficient:

mirage configure -t hvt

Note that the build products have changed:

The unikernel binary is now named <unikernel>.hvt, the ukvm-bin binary is now named solo5-hvt.

• adapt to mirage-protocols, mirage-stack, tcpip changes (#920, by @hannesm)

This is a breaking change: mirage 3.2.0 requires mirage-protocols 1.4.0, mirage-stack 1.3.0, and tcpip 3.5.0 to work (charru-client-mirage 0.10 and mirage-qubes-ipv4 0.6 are adapted to the changes). An older mirage won't be able to use these new libraries correctly. Conflicts were introduced in the opam-repository.

In more detail, direct and socket stack initialisation changed, which is automatically generated by the mirage tool for each unikernel (as part of main.ml). A record was built up, which is no longer needed.

Several unneeded type aliases were removed: netif from Mirage_protocols.ETHIF ethif and prefix from Mirage_protocols.IP ip from Mirage_protocols.{UDP,TCP} netif and 'netif config from Mirage_stack.V4 'netif stackv4_config and socket_stack_config in Mirage_stack

• squash unnecessary warning from mirage build (#916, by @mato)

• use an int64 representing nanoseconds as the argument for TIME.sleep, instead of a float representing seconds. (#547, by @hannesm)

• expose new targets virtio and ukvm via the solo5 project. (#565, by @djwillia, @mato, and @hannesm).

• remove users of base_context, which includes command-line arguments --unix and --xen, and config.ml functions add_to_ocamlfind_libraries and add_to_opam_packages. As a side effect, fix a long-standing error message bug when invoking mirage against a config.ml that does not build. (#560, by @yomimono)

• link libgcc.a only on ARM & other build improvements (#544, by @hannesm)

• allow users to use crunch on unix with kv_ro; clean up crunch .mlis on clean (#556, by @yomimono)

• remove console arguments to network functors (#554, by @talex5 and @yomimono)

• standardize ip source and destination argument names as src and dst, and source and destination ports as src_port and dst_port (#546, by @yomimono)

• a large number of documentation improvements (#549, by @djs55)

• require pseudoheader function for IP module types. (#541, by @yomimono)

• always build with ocamlbuild -r, to avoid repetitive failure message (#537, by @talex5)

2.9.1 (2016-07-20)

• Warn users of command-line arguments --unix and --xen that support for these will soon be dropped. Instead, use -t unix and -t xen respectively. (see https://github.com/mirage/mirage-www/pull/475#issuecomment-233802501) (#561, by @yomimono)

• Warn users of functions add_to_opam_packages p and add_to_ocamlfind_libraries l that support for these will soon be dropped. Instead, use register ~libraries:l and register:~packages:p respectively. (#561, by @yomimono).

2.9.0 (2016-04-29)

• Add logging support. A new reporter parameter to register is now available. This parameter defines how to configure the log reporter, using Logs and Mirage_logs. Log reporters can also be configured at configuration AND runtime using on the new -l or --logs command-line argument. (#534, by @samoht, @talex5 and @Drup)

• Allow to disable command-line parsing at runtime. There is a new argv parameter to the register function to allow to pass custom command-line argument parsing devices. Use register ~argv:no_argv to disable command-line argument parsing. (#493, by @samoht and @Drup)

2.8.0 (2016-04-04)

• Define an ICMP and ICMPV4 module type. ICMPV4 is included in, and surfaced by, the STACKV4 module type. The previous default behavior of the IPv4 module with respect to ICMP is preserved by STACKV4 and the tcpip_stack_direct function provided by mirage. (#523, by @yomimono)

• Explicitly require OCaml compiler version 4.02.3 in opam files for mirage-types and mirage.

2.7.3 (2016-03-20)

• Fix another regression introduced in 2.7.1 which enable -warn-error by default. This is now controlled by a --warn-error flag on mirage configure. Currently it's default value is [false] but this might change in future versions (#520)

2.7.2 (2016-03-20)

• Fix regression introduced in 2.7.1 which truncates the ouput of opam install and breaks opam depext (#519, by @samoht)

2.7.1 (2016-03-17)

• Improve the Dockerfile (#507, by @avsm)

• Use Astring (by @samoht)

• Clean-up dependencies automatically added by the tool

  • do not require lwt.syntax, cstruct.syntax and sexplib, which should make the default unikernels camlp4-free (#510, #515 by @samoht)

  • always require mirage-platform (#512, by @talex5)

  • ensure that mirage-types and mirage-types-lwt are installed

• Turn on more warnings and enable "warning as errors".

• Check that the OCaml compiler is at least 4.02.3 (by @samoht)

2.7.0 (2016-02-17)

The mirage tool is now based on functoria. (#441 #450, by @drup @samoht) See https://mirage.io/blog/introducing-functoria for full details.

• Command line interface: The config file must be passed with the -f option (instead of being just an argument).

• Two new generic combinators are available, generic_stack and generic_kv_ro.

• get_mode is deprecated. You should use keys instead. And in particular Key.target and Key.is_xen.

• add_to_ocamlfind_libraries and add_to_opam_packages are deprecated. Both the foreign and the register functions now accept the ~libraries and ~packages arguments to specify library dependencies.

• If you were using tls without the conduit combinator, you will be greeted during configuration by a message like this:

The "nocrypto" library is loaded but entropy is not enabled! Please enable the entropy by adding a dependency to the nocrypto device. You can do so by adding ~deps:[abstract nocrypto] to the arguments of Mirage.foreign.

Data dependencies (such as entropy initialization) are now explicit.
In order to fix this, you need to declare the dependency like so:
```ocaml
open Mirage

let my_functor =
let deps = [abstract nocrypto] in
foreign ~deps "My_Functor" (foo @-> bar)

My_functor.start will now take an extra argument for each dependencies. In the case of nocrypto, this is ().

• Remove nat-script.sh from the scripts directory, to be available as an external script.

2.6.1 (2015-09-08)

• Xen: improve the .xl file generation. We now have

  • name.xl: this has sensible defaults for everything including the network bridges and should "just work" if used on the build box

  • name.xl.in: this has all the settings needed to boot (e.g. presence of block and network devices) but all the environmental dependencies are represented by easily-substitutable variables. This file is intended for production use: simply replace the variables for the paths, bridges, memory sizes etc. and run xl create as before.

2.6.0 (2015-07-28)

• Better ARP support. This needs mirage-tcpip.2.6.0 (#419, by @yomimono)

  • [mirage-types] Remove V1.IPV4.input_arp

  • [mirage-types] Expose V1.ARP and V1_LWT.ARP

  • Expose a Mirage.arp combinator

• Provide noop configuration for default_time (#435, by @yomimono)

• Add Mirage.archive and Mirage.archive_of_files to support attaching files via a read-only tar-formatted BLOCK (#432, by @djs55)

• Add a .merlin file (#428, by @Drup)

2.5.1 (2015-07-17)

• [mirage-types] Expose V1_LWT.FS.page_aligned_buffer = Cstruct.t

2.5.0 (2015-06-10)

• Change the type of the Mirage.http_server combinator. The first argument (the conduit server configuration) is removed and should now be provided at compile-time in unikernel.ml instead of configuration-time in config.ml:

(* [config.ml] ) ( in 2.4 ) let http = http_server (TCP (Port 80)) conduit ( in 2.5 *) let http = http_server conduit

(* [unikernel.ml] ) let start http = ( in 2.4 ) http (S.make ~conn_closed ~callback ()) ( in 2.5 *) http (`TCP 80) (S.make ~conn_closed ~callback ()) ```

• Change the type of the Mirage.conduit_direct combinator. Previously, it took an optional vchan implementation, an optional tls immplementation and an optional stackv4 implemenation. Now, it simply takes a stackv4 implementation and a boolean to enable or disable the tls stack. Users who want to continue to use vchan with conduit should now use the Vchan functors inside unikernel.ml instead of the combinators in config.ml. To enable the TLS stack:

(* [config.ml] *) let conduit = conduit_direct ~tls:true (stack default_console)

(* [unikernel.ml] *) module Main (C: Conduit_mirage.S): struct let start conduit = C.listen conduit (TLS (tls_config, TCP 443)) callback end ```

• [types] Remove V1.ENTROPY and V1_LWT.ENTROPY. The entropy is now handled directly by nocrypto.0.4.0 and the mirage-tool is only responsible to call the Nocrypto_entropy_{mode}.initialize function.

• Remove Mirage.vchan, Mirage.vchan_localhost, Mirage.vchan_xen and Mirage.vchan_default. Vchan users need to adapt their code to directly use the Vchan functors instead of relying on the combinators.

• Remove Mirage.conduit_client and Mirage.conduit_server types.

• Fix misleading "Compiling for target" messages in mirage build (#408 by @lnmx)

• Add --no-depext to disable the automatic installation of opam depexts (#402)

• Support @name/file findlib's extended name syntax in xen_linkopts fields. @name is expanded to %{lib}%/name

• Modernize the Travis CI scripts

2.4.0 (2015-05-05)

• Support mirage-http.2.2.0

• Support conduit.0.8.0

• Support tcpip.2.4.0

• Add time and clock parameters to IPv4 (#362, patch from @yomimono)

• Support for ocaml-tls 0.4.0.

• Conduit now takes an optional TLS argument, allowing servers to support encryption. (#347)

• Add the ability to specify Makefile.user to extend the generated Makefile. Also all, build and clean are now extensible make targets.

• Remove the mirage run command (#379)

• Call opam depext when configuring (#373)

• Add opam files for mirage and mirage-types packages

• Fix mirage --version (#374)

• Add a update-doc target to the Makefile to easily update the online documentation at http://mirage.github.io/mirage/

2.3.0 (2015-03-10)

• Remove the IO_PAGE module type from V1. This has now moved into the io-page pacakge (#356)

• Remove DEVICE.connect from the V1 module types. When a module is functorised over a DEVICE it should only have the ability to use devices it is given, not to connect to new ones. (#150)

• Add FLOW.error_message to the V1 module types to allow for generic handling of errors. (#346)

• Add IP.uipaddr as a universal IP address type. (#361)

• Support the entropy version 0.2+ interfaces. (#359)

• Check that the opam command is at least version 1.2.0 (#355)

• Don't put '-classic-display' in the generated Makefiles. (#364)

2.2.1 (2015-01-29)

• Fix logging errors when mirage output is not redirected. (#355)

• Do not reverse the order of C libraries when linking. This fixes Zarith linking in Xen mode. (#341).

• Fix typos in command line help. (#352).

2.2.0 (2014-12-18)

• Add IPv6 support. This alters some of the interfaces that were previously hardcoded to IPv4 by generalising them. For example:

type v4 type v6

type 'a ip type ipv4 = v4 ip type ipv6 = v6 ip ```

Full support for configuring IPv6 does not exist yet, as this release is intended for getting the type definitions in place before adding configuration support.

2.1.1 (2014-12-10)

• Do not reuse the Unix linker options when building Xen unikernels. Instead, get the linker options from the ocamlfind xen_linkopts variables (#332). See tcpip.2.1.0 for a library that does this for a C binding.

• Only activate MacOS X compilation by default on 10.10 (Yosemite) or higher. Older revisions of MacOS X will use the generic Unix mode by default, since the vmnet framework requires Yosemite or higher.

• Do not run crunched filesystem modules through camlp4, which significantly speeds up compilation on ARM platforms (from minutes to seconds!) (#299).

2.1.0 (2014-12-07)

• Add specific support for MacOSX as a platform, which enables network bridging on Yosemite (#329). The --unix flag will automatically activate the new target if run on a MacOS X host. If this breaks for you due to being on an older version of MacOS X, then use the new --target flag to set either Unix, MacOSX or Xen to the mirage configure command.

• Add mirage.runtime findlib library and corresponding Mirage_runtime module (#327).

• If net driver in STACKV4_direct can't initialize, print a helpful error (#164).

• [xen]: fixed link order in generated Makefile (#322).

• Make Lwt.tracing instructions work for Fish shell too by improving quoting (#328).

2.0.1 (2014-11-21)

• Add register ~tracing to enable tracing with mirage-profile at start-up (#321).

• Update Dockerfile for latest libraries (#320).

• Only build mirage-types if Io_page is also installed (#324).

2.0.0 (2014-11-05)

• [types]: backwards incompatible change: CONSOLE is now a FLOW; 'write' has a different signature and 'write_all' has been removed.

• Set on_crash = 'preserve' in default Xen config.

• Automatically install dependencies again, but display the live output to the user.

• Include C stub libraries in linker command when generating Makefiles for Xen.

• Add Vchan, Conduit and Resolver code generators.

• Generate a *.xe script which can upload a kernel to a XenServer.

• Generate a libvirt *.xml configuration file (#292).

• Fix determination of mirage-xen location for paths with spaces (#279).

• Correctly show config file locations when using a custom one.

• Fix generation of foreign (non-functor) modules (#293)

1.2.0 (2014-07-05)

The Mirage frontend tool now generates a Makefile with a make depend target, instead of directly invoking OPAM as part of mirage configure. This greatly improves usability on slow platforms such as ARM, since the output of OPAM as it builds can be inspected more easily. Users will now need to run make depend to ensure they have the latest package set, before building their unikernel with make as normal.

• Improve format of generated Makefile, and also colours in terminal output.

• Add make depend target to generated Makefile.

• Set OPAMVERBOSE and OPAMYES in the Makefile, which can be overridden.

• Add an ENTROPY device type for strong random sources (#256).

1.1.3 (2014-06-15)

• Build OPAM packages in verbose mode by default.

• [types] Add FLOW based on TCPV4.

• travis: build mirage-types from here, rather than 1.1.0.

1.1.2 (2014-04-01)

• Improvement to the Amazon EC2 deployment script.

• [types] Augment STACKV4 with an IPV4 module in addition to TCPV4 and UDPV4.

• Regenerate with OASIS 0.4.4 (which adds natdynlink support)

1.1.1 (2014-02-21)

• Man page fixes for typos and terminology (#220).

• Activate backtrace recording by default (#225).

• Fixes in the V1.STACKV4 to expose UDPv4/TCPv4 types properly (#226).

1.1.0 (2014-02-05)

• Add a combinator interface to device binding that makes the functor generation significantly more succinct and expressive. This breaks backwards compatibility with config.ml files from the 1.0.x branches.

• Integrate the mirage-types code into types. This is built as a separate library from the command-line tool, via the install-types Makefile target.

1.0.4 (2014-01-14)

• Add default build tags for annot, bin_annot, principal and strict_sequence.

• Renane KV_RO to Crunch

1.0.3 (2013-12-18)

• Do not remove OPAM packages when doing mirage clean (#143)

• [xen] generate a simple main.xl, without block devices or network interfaces.

• The HTTP dependency now also installs mirage-tcp-* and mirage-http-*.

• Fix generated Makefile dependency on source OCaml files to rebuild reliably.

• Support Fat_KV_RO (a read-only k/v version of the FAT filesystem).

• The Unix KV_RO now passes through to the underlying filesystem instead of calling crunch, via mirage-fs-unix.

1.0.2 (2013-12-10)

• Add HTTP support.

• Fix KV_RO configuration for OPAM autoinstall.

1.0.1 (2013-12-09)

• Add more examples to the FAT filesystem test case.

• Fix mirage-tcpip-* support

• Fix mirage-net-* support

1.0.0 (2013-12-09)

• Adapt the latest library releases for Mirage 1.0 interfaces.

0.10.0 (2013-12.08)

• Complete API rewrite

• [xen] XL configuration phase is now created during configure phase, was during run phase.

0.9.7 (2013-08-09)

• Generate code that uses the Ipaddr.V4 interface instead of Nettypes.

0.9.6 (2013-07-26)

• fix unix-direct by linking the unix package correctly (previously it was always dropped).

0.9.5 (2013-07-18)

• completely remove the dependency on obuild: use ocamlbuild everywhere now.

• adapt for mirage-0.9.3 OS.Netif interfaces (abstract type id).

• do not output network config when there are no ip-* lines in the .conf file.

• do not try to install mirage-fs if there is no filesystem to create.

• added nat-script.sh to setup xenbr0 with DNS, DHCP and masqerading under Linux.

0.9.4 (2013-07-09)

• build using ocamlbuild rather than depending on obuild.

• [xen] generate a symbol that can be used to produce stack traces with xenctx.

• mirari run --socket just runs the unikernel without any tuntap work.

• mirari run --xen creates a xl config file and runs xl create -c unikernel.xl.

0.9.3 (2013-06-12)

• Add a --socket flag to activate socket-based networking (UNIX only).

• Do not use OPAM compiler switches any more, as that's done in the packaging now.

• Use fd-passing in the UNIX backend to spawn a process.

0.9.2 (2013-03-28)

• Install obuild automatically in all compiler switches (such as Xen).

• Only create symlinks to mir-foo for a non-Xen target.

• Add a mirari clean command.

• Add the autoswitch feature via mirari --switch=<compiler> or the config file.

0.9.1 (2013-02-13)

• Fix Xen symlink upon build.

• Add a --no-install option to mirari configure to prevent invoking OPAM automatically.

0.9.0 (2013-02-12)

• Automatically install mirage-fs package if a filesystem crunch is requested.

• Remove the need for mir-run by including the final Xen link directly in Mirari.

• Add support for building Xen variants.

• Initial import of a unix-direct version.
