Wow, timekeeping is *complicated*. See the full discussion at http://www.freelists.org/post/rumpkernel-users/Implement-timekeeping-for-ru= mprunhw-x86 Any testing will be much appreciated.

I have plenty of segfaulting examples. I don't have time to work on that yet, so don't really consider it for testing. This was really a proof of concept to show that it is doable with OCaml (which was far from obvious when I started hacking). Currently this rely on gnu-(as/ld) specific behaviours and wasn't tested at all on anything else than my debian laptop. If you want to spend some time to track the bug. It is probably related to the change in the frame-descriptors representation or to the changes of https://github.com/ocaml/ocaml/pull/177 (also included in the branch). By the way if you are interested, one of the remaining questions is how to do that in a compatible way. The main difficulty being the representation of frame descriptors: to be able to reference them, yet not force them alive in the binary and have them alive if and only if the function they reference is alive. to do that I use a combination of trick: every frame descriptor and function is in its own section, the functions and associated frame descriptors sections are in the same section group and I add a symbol before the frame descriptor sections and another one after (that are not in the same sections as the frame descriptors).

I have created https://github.com/ocaml/opam-repository/pull/4383 to be able to test it a bit more easily. I suspect some libraries will not work fine with 4.03 so it will be difficult to test mirage-www with the compiler, but I'll try anyway. > Right, not a great success so far: the compilation is broken on OSX and I got segfaults when compiling camlp4, cmdliner and cppo on x86 :-) > > Is there anything more useful to report to help you fix the issues? and where should I report such issues? the bug tracker on your fork is not available. > > Best, > Thomas Don't bother reporting that yet. I have plenty of segfaulting examples. I don't have time to work on that yet, so don't really consider it for testing. This was really a proof of concept to show that it is doable with OCaml (which was far from obvious when I started hacking). Currently this rely on gnu-(as/ld) specific behaviours and wasn't tested at all on anything else than my debian laptop. If you want to spend some time to track the bug. It is probably related to the change in the frame-descriptors representation or to the changes of https://github.com/ocaml/ocaml/pull/177 (also included in the branch). By the way if you are interested, one of the remaining questions is how to do that in a compatible way. The main difficulty being the representation of frame descriptors: to be able to reference them, yet not force them alive in the binary and have them alive if and only if the function they reference is alive. to do that I use a combination of trick: every frame descriptor and function is in its own section, the functions and associated frame descriptors sections are in the same section group and I add a symbol before the frame descriptor sections and another one after (that are not in the same sections as the frame descriptors). The part that is probably not portable are: * section groups is probably a (almost undocumented...) feature of gnu-(as/ld) (I didn't verify that it exists elsewhere). * -gc-sections option may be a gnu-ld only feature * I rely on the order in which section ends up in the binary. There is a way to enforce that with gnu-ld (per object file linker scripts), but i'm not certain it exists elsewhere (and gnu-ld seems not to handle it on windows either).

We=E2=80=99ve just pushed a new post = live that describes how to create secure unikernels using mirage-seal. =  It also includes instructions for how to get (and sign) = certificates, which is typically one of the more laborious = tasks.

Please = do try it out and let us know how you get on!

Piles of upper bounds constraints are fine when a new version of a package is released, since it's then a valid upper bound. The issue was to do with having upper bounds by default, which make it very hard to pin development versions of packages. Default upper bounds are also pessimal: right now, the common case is that a new package release doesn't break the interface (and we add an upper bound when it does break). > > Specifically -- I was proposing that CI testing should be CI testing > (not simply "does it still build" testing), by building some of the > depends-on packages against the newly built library in question. > DavidS noted that REVDEPS (IIRC) is already a supported variable for > the ocaml-travisci-skeleton scripts and needn't be set to "*" as it > often currently is, but could be set to a few chosen reverse > dependencies to at least try and avoid (or detect anyway) major > downstream breakage. > > Ie., I think that with a few minor additions to relevant .travis.yml > files, this bit of the situation can probably be improved immediately. > (I have the impression that many Mirage libraries already use the > skeleton scripts.) What specific additions do you have in mind? Please do file issues on the ocaml-travis-ci-skeleton repo with any ideas. More importantly, it's worth sweeping through older libraries that haven't been updated in a while and making sure they all use the skeleton scripts. I've done this for around 20 or so libraries in recent months, so it's generally better. -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Tue Jul 07 18:23:00 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 07 Jul 2015 18:23:00 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCXW7-0004SX-BW; Tue, 07 Jul 2015 18:22:51 +0000 Received: from mail6.bemta14.messagelabs.com ([193.109.254.103]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCXW6-0004SJ-7c for mirageos-devel@lists.xenproject.org; Tue, 07 Jul 2015 18:22:50 +0000 Received: from [193.109.254.147] by server-15.bemta-14.messagelabs.com id 3D/F4-18947-9F81C955; Tue, 07 Jul 2015 18:22:49 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-12.tower-27.messagelabs.com!1436293368!30104459!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.7 required=7.0 tests=BODY_RANDOM_LONG, RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 16060 invoked from network); 7 Jul 2015 18:22:48 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-12.tower-27.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 7 Jul 2015 18:22:48 -0000 Received: from [192.168.1.75] (cpc7-cmbg14-2-0-cust238.5-4.cable.virginm.net [86.30.244.239]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 7ff9056b; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Tue, 7 Jul 2015 19:22:48 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: Date: Tue, 7 Jul 2015 19:22:46 +0100 Message-Id: <20A84A35-44E9-448F-9004-78B259EFB0AB@recoil.org> References: <43C2553A-7EB8-4227-9317-BB0D657F2BFE@recoil.org> To: Richard Mortier X-Mailer: Apple Mail (2.2098) Cc: mirageos-devel Subject: Re: [MirageOS-devel] MirageOS fortnightly call - Wednesday 1st at 4pm BST X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 6 Jul 2015, at 20:26, Richard Mortier wrote: >> *ThomasG:* Mirage is a set of libraries that work together and a frontend tool that glues >> them together.

I've put a trial PR in for ocaml-cohttp to see how it goes. -- Richard Mortier richard.mortier@cl.cam.ac.uk _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Wed Jul 08 10:57:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Wed, 08 Jul 2015 10:57:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCn2L-0006e5-EQ; Wed, 08 Jul 2015 10:57:09 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCn2K-0006di-3m for mirageos-devel@lists.xenproject.org; Wed, 08 Jul 2015 10:57:08 +0000 Received: from [85.158.139.211] by server-12.bemta-5.messagelabs.com id EF/EF-25925-3020D955; Wed, 08 Jul 2015 10:57:07 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-16.tower-206.messagelabs.com!1436353026!16846321!1 X-Originating-IP: [209.85.216.52] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 20833 invoked from network); 8 Jul 2015 10:57:06 -0000 Received: from mail-vn0-f52.google.com (HELO mail-vn0-f52.google.com) (209.85.216.52) by server-16.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 8 Jul 2015 10:57:06 -0000 Received: by vnbf62 with SMTP id f62so14618592vnb.8 for ; Wed, 08 Jul 2015 03:57:05 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=+CHL/9OmFaESut3weMVwTi4FRKr0fA9yXCR1Jzl2U1I=; b=m0B7kV/gJmgpZaC5rde96kqD0vllajnF/VJASw01Kn/jH3wXrGBiOR8KR5Qn7Y4L7Z /Wgg6NFx0cPoUs6+hGl5mwUQRD28AsHOrtAGATDaGkFgg6MMH4f2j4HK8meXDP/4m3y1 6Y3kswnOOB11ZdhxF/0fWLl9p5x++AIBLgGWt947slaLBy4j1BXsjVao8rwP31aaaekL A7pjcw6m3dMuIFPEzPJ6OmYVJGpQfNwIMVxC8tTRHj38kakbqh/cQn6tLT7gFCIdtrx+ K8V4YY2SuCEkWACS0RGlSSiIr+5iCc2AGIHBs1uoLv3MVWZGA22uUk9vfNOEOSRRlEv+ vW5Q== MIME-Version: 1.0 X-Received: by 10.52.52.114 with SMTP id s18mr9770493vdo.9.1436353025833; Wed, 08 Jul 2015 03:57:05 -0700 (PDT) Received: by 10.31.65.132 with HTTP; Wed, 8 Jul 2015 03:57:05 -0700 (PDT) In-Reply-To: References: Date: Wed, 8 Jul 2015 11:57:05 +0100 Message-ID: From: Thomas Leonard To: Kees van steenwyk Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] sshtunnel X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 8 July 2015 at 03:51, Kees van steenwyk wrote: > Hi, > > I have been trying to build a unikernel that will serve the "ssh -D ..." > command.

I haven't checked, but you might be able to use the ocaml-ssh library as a starting point: https://github.com/avsm/ocaml-ssh/ If you want to use the C implementation instead, you'll need to find out how it sends the data. If it provides a flexible API then you can just call into the C libraries as external functions and pass the data to the network stack from your OCaml code (see e.g. nocrypto for an example of calling C code from Mirage). If the C code needs a POSIX interface then you might be better off using a rumpkernel, though you could implement the necessary stubs in Mirage too. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Wed Jul 08 10:57:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Wed, 08 Jul 2015 10:57:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCn2L-0006e5-EQ; Wed, 08 Jul 2015 10:57:09 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZCn2K-0006di-3m for mirageos-devel@lists.xenproject.org; Wed, 08 Jul 2015 10:57:08 +0000 Received: from [85.158.139.211] by server-12.bemta-5.messagelabs.com id EF/EF-25925-3020D955; Wed, 08 Jul 2015 10:57:07 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-16.tower-206.messagelabs.com!1436353026!16846321!1 X-Originating-IP: [209.85.216.52] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 20833 invoked from network); 8 Jul 2015 10:57:06 -0000 Received: from mail-vn0-f52.google.com (HELO mail-vn0-f52.google.com) (209.85.216.52) by server-16.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 8 Jul 2015 10:57:06 -0000 Received: by vnbf62 with SMTP id f62so14618592vnb.8 for ; Wed, 08 Jul 2015 03:57:05 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=+CHL/9OmFaESut3weMVwTi4FRKr0fA9yXCR1Jzl2U1I=; b=m0B7kV/gJmgpZaC5rde96kqD0vllajnF/VJASw01Kn/jH3wXrGBiOR8KR5Qn7Y4L7Z /Wgg6NFx0cPoUs6+hGl5mwUQRD28AsHOrtAGATDaGkFgg6MMH4f2j4HK8meXDP/4m3y1 6Y3kswnOOB11ZdhxF/0fWLl9p5x++AIBLgGWt947slaLBy4j1BXsjVao8rwP31aaaekL A7pjcw6m3dMuIFPEzPJ6OmYVJGpQfNwIMVxC8tTRHj38kakbqh/cQn6tLT7gFCIdtrx+ K8V4YY2SuCEkWACS0RGlSSiIr+5iCc2AGIHBs1uoLv3MVWZGA22uUk9vfNOEOSRRlEv+ vW5Q== MIME-Version: 1.0 X-Received: by 10.52.52.114 with SMTP id s18mr9770493vdo.9.1436353025833; Wed, 08 Jul 2015 03:57:05 -0700 (PDT) Received: by 10.31.65.132 with HTTP; Wed, 8 Jul 2015 03:57:05 -0700 (PDT) In-Reply-To: References: Date: Wed, 8 Jul 2015 11:57:05 +0100 Message-ID: From: Thomas Leonard To: Kees van steenwyk Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] sshtunnel X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 8 July 2015 at 03:51, Kees van steenwyk wrote: > Hi, > > I have been trying to build a unikernel that will serve the "ssh -D ..." > command.

A possible workaround is to add prefix to the module names (Tftp_wirte and Tftp) and keep the two ocamlfind packages. If you have unix dependencies, one common scheme is to have Tftp_unix and tftp.unix. Same for mirage: Tftp_mirage and tftp.mirage. > 3.

We are still waiting for the new OCaml doc generator to improve that :-) A popular ocamldoc' style is Daniel's one. Could be enable by putting [3] in your doc directory and [4] in your myocamlbuild.ml.

So instead of: module Make(C:V1_LWT.CONSOLE)(FS:V1_LWT.KV_RO)(S:V1_LWT.STACKV4) : sig [blabla] end you could write: module type S = sig [blabla + some abstract types] end module Make(C:V1_LWT.CONSOLE)(FS:V1_LWT.KV_RO)(S:V1_LWT.STACKV4): S with type [type constraints] Sometimes the gain is not totally clear (as you have to define abstract types) but it usually makes the documentation is bit clearer. Thomas --- Here are a rough description of my workflow and random thoughts associated to it: ### Setup Starting from scratch on a new machine, I need: - `opam install ocp-indent tuareg merlin` - Set-up `.emacs` manually (by copying my [dotfiles](https://github.com/samoht/dotfiles)] What could be (or is) improving: - `opam install user-setup` ? [need to test] - `opam install opam-tools` [todo] ### Create a new project - copy _oasis from somewhere else - copy basic alcotest skeleton from another project - start writing code (first `.mli` and then `.ml`) - generate _oasis autogen (Makefile, _tags, setup.ml, ...) - create a repo on Github - create an opam file - copy ocaml-travisci-skeletons - activate testing on TravisCI website - edit Makefile to add version.ml generation - edit Makefile to add gh-pages generation - edit _tags to add nicer ocamldoc options - init gh-pages manually, copy Daniel's css from somewhere else - edit Makefile to add release scripts What can be or is improving: - `opam-publish` helps (but not fully) - need more tool - coverall (seems to work fine, but didn't try yet) ### Testing - create a branch for new commits, open a PR to run TracisCI - add tests ### Releasing - bump version number - regen `_oasis` auto-gen crap - `make release` (when the project is well configured) - look at TravisCI results on opam-repository - slow to get feedback (often 2h+ because of slow OSX workers on other builds) - usually fine, but sometime errors are not displayed properly (ex. cyclic dependency in my last PR) What can be or is improving: - need more precise feedback - need faster feedback ### Maintenance - online docs: `make gh-pages`, hosted on gh-pages What can be or is improving: - usual ocamldoc flows: - no cross-project references - missing module expansion - need better integration with the workflow. - could be a post-hook script on TravisCI scripts (as for deployment of unikernels) - could also be a crawler bot who creates PR on projects - could also be centralized on opam docs website > -- > Richard Mortier > richard.mortier@cl.cam.ac.uk > > _______________________________________________ > MirageOS-devel mailing list > MirageOS-devel@lists.xenproject.org > http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jul 09 11:01:44 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 09 Jul 2015 11:01:44 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZD9aD-0000hJ-OX; Thu, 09 Jul 2015 11:01:37 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZD9aC-0000gw-NJ for MirageOS-devel@lists.xenproject.org; Thu, 09 Jul 2015 11:01:36 +0000 Received: from [85.158.137.68] by server-1.bemta-3.messagelabs.com id 87/30-10437-0945E955; Thu, 09 Jul 2015 11:01:36 +0000 X-Env-Sender: thomas.gazagnaire@gmail.com X-Msg-Ref: server-5.tower-31.messagelabs.com!1436439690!24246747!1 X-Originating-IP: [209.85.212.181] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 5414 invoked from network); 9 Jul 2015 11:01:30 -0000 Received: from mail-wi0-f181.google.com (HELO mail-wi0-f181.google.com) (209.85.212.181) by server-5.tower-31.messagelabs.com with RC4-SHA encrypted SMTP; 9 Jul 2015 11:01:30 -0000 Received: by wiclp1 with SMTP id lp1so106262429wic.0 for ; Thu, 09 Jul 2015 04:01:30 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=sender:content-type:mime-version:subject:from:in-reply-to:date:cc :content-transfer-encoding:message-id:references:to; bh=vBQZaD5ZEH5bvPE/u4W0KDnnfnX7ihaBYvNSQ87/dM4=; b=Ox7DWTPbR1kpWP/wcHxNSi66PJ5uyqISyR+8vs/QlUHWahj1q2LOzAgs0suqvE3CpK 54UmehLcpWYA2/ZXH4B8BGgkHXb+aF02351+w/yi4GYVzUAC1KGzsPwkNRh/1NwjR5tn dUCHxRLasJKwO0Vvs9yg2PfXupbPehh5LFJ/P5l+GxaGJnUvfUGWiGta36FuwUIFuDan ME7MXbtx4qiyXW89+DGMeTFGm0qxzHu/Xx6wW1QkC/cK4CxsOt0UrxwwxLplR7lfyf6U 3D12WF7CKcaL5MNqncgXWHi7X/cgGv0Du0SfY3/8sSjrT8wDOIFkAXsr9dfKg3Z4tl43 dtZA== X-Received: by 10.180.103.194 with SMTP id fy2mr87855603wib.55.1436439689956; Thu, 09 Jul 2015 04:01:29 -0700 (PDT) Received: from piana.mac.cl.cam.ac.uk (piana.mac.cl.cam.ac.uk.

I was maybe planning to write something similar to publish docs (or adapt[2] to run as a script) but it is not done yet.

A possible workaround is to add prefix to the module names (Tftp_wirte and Tftp) and keep the two ocamlfind packages. If you have unix dependencies, one common scheme is to have Tftp_unix and tftp.unix. Same for mirage: Tftp_mirage and tftp.mirage. > 3.

We are still waiting for the new OCaml doc generator to improve that :-) A popular ocamldoc' style is Daniel's one. Could be enable by putting [3] in your doc directory and [4] in your myocamlbuild.ml.

So instead of: module Make(C:V1_LWT.CONSOLE)(FS:V1_LWT.KV_RO)(S:V1_LWT.STACKV4) : sig [blabla] end you could write: module type S = sig [blabla + some abstract types] end module Make(C:V1_LWT.CONSOLE)(FS:V1_LWT.KV_RO)(S:V1_LWT.STACKV4): S with type [type constraints] Sometimes the gain is not totally clear (as you have to define abstract types) but it usually makes the documentation is bit clearer. Thomas --- Here are a rough description of my workflow and random thoughts associated to it: ### Setup Starting from scratch on a new machine, I need: - `opam install ocp-indent tuareg merlin` - Set-up `.emacs` manually (by copying my [dotfiles](https://github.com/samoht/dotfiles)] What could be (or is) improving: - `opam install user-setup` ? [need to test] - `opam install opam-tools` [todo] ### Create a new project - copy _oasis from somewhere else - copy basic alcotest skeleton from another project - start writing code (first `.mli` and then `.ml`) - generate _oasis autogen (Makefile, _tags, setup.ml, ...) - create a repo on Github - create an opam file - copy ocaml-travisci-skeletons - activate testing on TravisCI website - edit Makefile to add version.ml generation - edit Makefile to add gh-pages generation - edit _tags to add nicer ocamldoc options - init gh-pages manually, copy Daniel's css from somewhere else - edit Makefile to add release scripts What can be or is improving: - `opam-publish` helps (but not fully) - need more tool - coverall (seems to work fine, but didn't try yet) ### Testing - create a branch for new commits, open a PR to run TracisCI - add tests ### Releasing - bump version number - regen `_oasis` auto-gen crap - `make release` (when the project is well configured) - look at TravisCI results on opam-repository - slow to get feedback (often 2h+ because of slow OSX workers on other builds) - usually fine, but sometime errors are not displayed properly (ex. cyclic dependency in my last PR) What can be or is improving: - need more precise feedback - need faster feedback ### Maintenance - online docs: `make gh-pages`, hosted on gh-pages What can be or is improving: - usual ocamldoc flows: - no cross-project references - missing module expansion - need better integration with the workflow. - could be a post-hook script on TravisCI scripts (as for deployment of unikernels) - could also be a crawler bot who creates PR on projects - could also be centralized on opam docs website > -- > Richard Mortier > richard.mortier@cl.cam.ac.uk > > _______________________________________________ > MirageOS-devel mailing list > MirageOS-devel@lists.xenproject.org > http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jul 09 12:24:37 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 09 Jul 2015 12:24:37 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZDAsQ-0006PB-9e; Thu, 09 Jul 2015 12:24:30 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZDAsP-0006P6-Mi for mirageos-devel@lists.xenproject.org; Thu, 09 Jul 2015 12:24:29 +0000 Received: from [85.158.137.68] by server-12.bemta-3.messagelabs.com id ED/1A-02952-DF76E955; Thu, 09 Jul 2015 12:24:29 +0000 X-Env-Sender: hannes@mehnert.org X-Msg-Ref: server-10.tower-31.messagelabs.com!1436444667!24210806!1 X-Originating-IP: [213.73.89.200] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 6142 invoked from network); 9 Jul 2015 12:24:28 -0000 Received: from mail.mehnert.org (HELO mail.mehnert.org) (213.73.89.200) by server-10.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 9 Jul 2015 12:24:28 -0000 Received: from [128.232.110.147] (c147.al.cl.cam.ac.uk [128.232.110.147]) (using TLSv1 with cipher DHE-RSA-AES128-SHA (128/128 bits)) (Client CN "hannes@mehnert.org", Issuer "mehnert root CA" (not verified)) by mail.mehnert.org (Postfix) with ESMTPS id B54DC3CFD for ; Thu, 9 Jul 2015 14:24:26 +0200 (CEST) Message-ID: <559E67D4.4080905@mehnert.org> Date: Thu, 09 Jul 2015 13:23:48 +0100 From: Hannes Mehnert User-Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:31.0) Gecko/20100101 Thunderbird/31.7.0 MIME-Version: 1.0 To: "mirageos-devel@lists.xenproject.org" References: <43C2553A-7EB8-4227-9317-BB0D657F2BFE@recoil.org> In-Reply-To: OpenPGP: id=11B5464249B5BD858FFF6328BC896588DF7C28EE Subject: Re: [MirageOS-devel] MirageOS fortnightly call - Wednesday 1st at 4pm BST X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA384 On 07/06/2015 17:06, Anil Madhavapeddy wrote: > #### Networking stack > > There were various issues around duplicate acks and TCP > retransmission which were exposed due to the TLS stack integration. > Many of these were just regressions or lurking issues due to Lwt > mvars, and are now fixed. > > To stop them from coming back, we now have tests that run per PR > within Travis.

I'm now quite convinced that this should be done and would like to support this both at the API level and internally in ptime (which currently only has millisecond precision). I propose that the canonical representation should be the following one which is basically what a POSIX timespec definition [1] gives us and is OCaml 32-bit clean: type posix_t = int64 * int Understood as a signed, second precision, time span paired with a non-negative number of nano seconds ranging from 0 to 999'999'999. Formally a tuple `(s, ns)` represents the time that happens at `s + 1e-9 * ns` from the epoch. It also seems that there is consensus that the current CLOCK interface [2] is absurd, forcing any clock source implementer to come up with calendar field decomposition functions (gmtime). I think that the following interface would be sufficient: module type CLOCK = sig val now_s : unit -> int64 * int (** [now_s ()] is [(s, ns)] the operating system's POSIX timestamp for the current time understood as the number of seconds [s] + 1e-9 * [ns] from the epoch 1970-01-01 00:00:00 UTC.

I'm now quite convinced that this should be done and would like to support this both at the API level and internally in ptime (which currently only has millisecond precision). I propose that the canonical representation should be the following one which is basically what a POSIX timespec definition [1] gives us and is OCaml 32-bit clean: type posix_t = int64 * int Understood as a signed, second precision, time span paired with a non-negative number of nano seconds ranging from 0 to 999'999'999. Formally a tuple `(s, ns)` represents the time that happens at `s + 1e-9 * ns` from the epoch. It also seems that there is consensus that the current CLOCK interface [2] is absurd, forcing any clock source implementer to come up with calendar field decomposition functions (gmtime). I think that the following interface would be sufficient: module type CLOCK = sig val now_s : unit -> int64 * int (** [now_s ()] is [(s, ns)] the operating system's POSIX timestamp for the current time understood as the number of seconds [s] + 1e-9 * [ns] from the epoch 1970-01-01 00:00:00 UTC. [ns] ranges from [0] to [999_999_999]. *) val current_tz_offset_s : unit -> int (** [current_tz_offset_s ()] is the operating system's current local time zone offset to UTC in seconds. *) end Would people agree on such an API and change for the next major release of mirage ? If so, I'd be willing to actually delve into the various repos to make that happen.

One "standard" (used by a class of network monitoring hardware, supported by wireshark etc, with some accessor functions implemented -- albeit probably quite poorly and with terrible taste -- in my branch of pcap-format, https://github.com/mor1/ocaml-pcap/blob/master/lib/erf.ml) is the ERF timestamp. Single int64 representation, accurate to 233 ps. https://wiki.wireshark.org/ERF "The time of arrival of the cell, a ERF 64-bit timestamp. Single little-endian 64-bit fixed point number. The high 32-bits contain the integer number of seconds since the start of time (unix epoch time). The lower 32-bits contain the binary fraction of the second allowing an ultimate resolution of approximately 233 picoseconds." Not clear this is really what we'd want but something along those lines (fixed point, binary fractions) might work out sensibly if the accessors can be efficient. What range and precision do we want?

The base representation should be fast and at least support nanosecond precision (for eg profiling use cases), but I think size is less important. > 2.

Does the "ping" command suggested on the instructions page show anything? Usual way to start debugging this is to look at the output of `ifconfig` and `route` to see how the interface has been named, what address it has, and whether there're appropriate routes setup.

Does the "ping" command suggested on the instructions page show anything? Usual way to start debugging this is to look at the output of `ifconfig` and `route` to see how the interface has been named, what address it has, and whether there're appropriate routes setup. Then try `tcpdump` on the interfaces in question to see what packets are actually flowing, if any. If no-one else picks this up in the meantime, ping me again tomorrow and I'll try and get a VM setup to test. On 11 July 2015 at 21:12, Carl Dong wrote: > Tried.

Should I be asking in another mailing list? Looks like a bug in the FreeBSD port of OPAM -- it should also depend on the "ocaml-camlp4" port as well as OCaml. Try pkg_add'ing the ocaml-camlp4 package and retrying the installation. Alternatively, you can workaround this by "opam switch 4.02.2" and it will compile a local version of camlp4 and let you continue. -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Sat Jul 11 20:29:37 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Sat, 11 Jul 2015 20:29:37 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZE1Oz-0007AV-CM; Sat, 11 Jul 2015 20:29:37 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZE1Ox-0007AQ-Jw for mirageos-devel@lists.xenproject.org; Sat, 11 Jul 2015 20:29:35 +0000 Received: from [85.158.139.211] by server-10.bemta-5.messagelabs.com id 28/E5-11201-EAC71A55; Sat, 11 Jul 2015 20:29:34 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-11.tower-206.messagelabs.com!1436646574!16370494!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.7 required=7.0 tests=BODY_DONG,RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 18487 invoked from network); 11 Jul 2015 20:29:34 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-11.tower-206.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 11 Jul 2015 20:29:34 -0000 Received: from [192.168.0.15] (91.84.189.80.dyn.plus.net [80.189.84.91]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 56a38ae5; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Sat, 11 Jul 2015 21:29:33 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: <1436645919.1418292.321252433.0BBBABBF@webmail.messagingengine.com> Date: Sat, 11 Jul 2015 21:29:30 +0100 Message-Id: References: <1436645919.1418292.321252433.0BBBABBF@webmail.messagingengine.com> To: Carl Dong X-Mailer: Apple Mail (2.2098) Cc: mirageos-devel@lists.xenproject.org Subject: Re: [MirageOS-devel] Problem installing mirage on FreeBSD X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 11 Jul 2015, at 21:18, Carl Dong wrote: > > Hi all, > > I started with a fresh install of FreeBSD 10.1 Release and installed > opam from FreeBSD's ports collection.

It seems that when conduit came in, and HTTP was supported differently, the "hello" part of that example was removed, leaving only the console echo service. At present, if you type into the telnet session, you should see output on the console of the mir-stackv4 process. I've filed an issue to check the samples and update the docs. Will try and get this fixed in the next few days if no-one beats me to it. On 11 July 2015 at 21:27, Carl Dong wrote: > So... I've managed to get some things working...

It seems that when conduit came in, and HTTP was supported differently, the "hello" part of that example was removed, leaving only the console echo service. At present, if you type into the telnet session, you should see output on the console of the mir-stackv4 process. I've filed an issue to check the samples and update the docs. Will try and get this fixed in the next few days if no-one beats me to it. On 11 July 2015 at 21:27, Carl Dong wrote: > So... I've managed to get some things working...

[ps] is in the range \[[0];[86_399_999_999_999_999L]\= ]. *) UTC leap seconds make this confusing. I.e. 'd' is not exactly the number of (UTC) days since the epoch, but it will _inevitably_ be used for that, leading to glitches around midnight. I think if you're going to have a two-part timestamp anyway it would be better to pick a break point with no semantics.

[ps] is in the range \[[0];[86_399_999_999_999_999L]\= ]. *) UTC leap seconds make this confusing. I.e. 'd' is not exactly the number of (UTC) days since the epoch, but it will _inevitably_ be used for that, leading to glitches around midnight. I think if you're going to have a two-part timestamp anyway it would be better to pick a break point with no semantics. E.g. 2^56 picoseconds is about the same size as a day, won't be so easily mistaken for one, and will make some of the calculations more efficient.

As part of their tutorial & training schedule on that day, they are interested in possibly holding a 4-hour Unikernel event. I know it's last minute, but I am trying to see if there is anyone who might want to present at this potential event. In particular, I'd like to hear from: - Developers who can discuss the architecture of their unikernel - Experts who can discuss how to use a particular unikernel - Users who can give war stories, howto info, and/or lessons learned from working with a particular unikernel We are short on time, so please ping me in the next day or so if you think you might be interested (it won't phase me if you can't commit on the spur of the moment, but please let me know that you're thinking about it). I need to determine this week if we will be able to get enough presenters to make this worthwhile. This is a community-driven event, so I don't think we can get any help with travel or expenses. If you know anyone who might be interested, please feel free to forward this message appropriately. Thank you!

Hi, Qiuying

I sometime use OpenSSL to encrypt and decrypt files (two-step = verification recover code) using AES-256-CBC symmetric cipher (not sure if = Hannes and David think it=E2=80=99s a good idea=E2=80=A6).

For example,

encrypt file:

$ openssl aes-256-cbc -in recover-code.txt -out recover-code.= dat

decrypt file:
$ openssl aes-256-cbc -d -in recover-code.dat -out recover-code.= txt

Nocrypto of course implemented AES cipher [1] so you may give a try.=


Thanks,

Runhang

Hello everyone,

I am currently looking to write OCaml versions of OpenSSL cmdline tools (using our nocrypto, x509 and tls libraries), and would love some advice on what would be most helpful to have/prioritize.

Any suggestions?

Many thanks!

Hello everyone,

I am currently looking to write OCaml versions of OpenSSL cmdline tools (using our nocrypto, x509 and tls libraries), and would love some advice on what would be most helpful to have/prioritize.

Any suggestions?

Many thanks!

The tutorial material is quite old and now that we have a considerably larger set of libraries and facilities, could probably do with an extensive refresh. I've updated the first three pages that are there so they match the current situation of mirage-skeleton better -- https://github.com/mirage/mirage-skeleton/pull/98 and https://github.com/mirage/mirage-www/pull/370 -- comments on either welcome. > I see various issues: > 1) mirage-www is not minimalistic.

The tutorial material is quite old and now that we have a considerably larger set of libraries and facilities, could probably do with an extensive refresh. I've updated the first three pages that are there so they match the current situation of mirage-skeleton better -- https://github.com/mirage/mirage-skeleton/pull/98 and https://github.com/mirage/mirage-www/pull/370 -- comments on either welcome. > I see various issues: > 1) mirage-www is not minimalistic.

It's indeed a good idea to put all of this things in one place that apps can reuse easily. Currently`mirage-types` is an interface file only, so I'm not sure that's the right place to put these kind of things here.

I'd really like to have a s_client [1] replacement, in fact I've already been working on something along the lines [2].

Any pointers are appreciated :) Best Jeremias _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Thu Jul 23 10:10:28 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 23 Jul 2015 10:10:28 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIDSM-0004XS-7J; Thu, 23 Jul 2015 10:10:26 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIDSK-0004XJ-F2 for mirageos-devel@lists.xenproject.org; Thu, 23 Jul 2015 10:10:24 +0000 Received: from [85.158.139.211] by server-15.bemta-5.messagelabs.com id 6C/08-12200-F8DB0B55; Thu, 23 Jul 2015 10:10:23 +0000 X-Env-Sender: richard.mortier@gmail.com X-Msg-Ref: server-11.tower-206.messagelabs.com!1437646223!19001946!1 X-Originating-IP: [209.85.212.172] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 23695 invoked from network); 23 Jul 2015 10:10:23 -0000 Received: from mail-wi0-f172.google.com (HELO mail-wi0-f172.google.com) (209.85.212.172) by server-11.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 23 Jul 2015 10:10:23 -0000 Received: by wibud3 with SMTP id ud3so16856811wib.1 for ; Thu, 23 Jul 2015 03:10:23 -0700 (PDT) X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20130820; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=pVLwYrnAcBDtX84lNM2EXn5deymY/wRyeJHIpdLO2d4=; b=DdQWYCQ8Ihgqh18o6AMt2L2pkDfZUtCsfD9JY/38GFYIcbMntktAv7NYF+pS2/buWB mG0HXkUgkmNOuqmbyn78Xp94m+/UYWIYABYot1rStBGVC7dnBD7i+w0TkpOlyEEQHlhx AEKNayV2Qu8UflbjLncBt3mPoPV0SV8EgibAZLVVt+XI8B+YoC36VVns4bp0CBXO/1qN xWgwT9ezPQVpx6nBCYDO0SryIBrGE2uD+7snCFUrsX7mtHJo1y4yL8DlBvYT6LAjJIZq DDtylUP6Rxr9DJr/9FBseX3pUP+AWFxqCCKgXxDpCkmoFqx0MXUIC2xWj3C6Y+BdPdvw 9LJQ== X-Received: by 10.180.77.129 with SMTP id s1mr15647422wiw.67.1437646222952; Thu, 23 Jul 2015 03:10:22 -0700 (PDT) Received: from mail-wi0-f173.google.com (mail-wi0-f173.google.com.

All things are possible, to some extent :) That's actually something we've discussed -- Mindy Preston was starting to work on it. The approach we were taking was roughly to use Irmin to serialise state -- a first prototype doing this for ARP is at https://github.com/yomimono/irmin-arp. Extending this to the full TCP/IP stack is definitely an interesting thing to try!

Yep -- pickling the TCP state should be fairly straightforward, since most of the stack supports s-expression converters. The trick is reconstructing it and ensuring that all the right hooks (such as timers) are all fired as a result. What sort of userland API did you have in mind for your application?

Do you mind linking directly against the OCaml TCP/IP stack? -anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Fri Jul 24 12:01:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Fri, 24 Jul 2015 12:01:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIbfG-0002sm-MM; Fri, 24 Jul 2015 12:01:22 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIbfF-0002sI-7n for mirageos-devel@lists.xenproject.org; Fri, 24 Jul 2015 12:01:21 +0000 Received: from [85.158.139.211] by server-3.bemta-5.messagelabs.com id 29/87-13798-01922B55; Fri, 24 Jul 2015 12:01:20 +0000 X-Env-Sender: geo.couprie@gmail.com X-Msg-Ref: server-7.tower-206.messagelabs.com!1437739279!23456147!1 X-Originating-IP: [209.85.217.172] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 26855 invoked from network); 24 Jul 2015 12:01:19 -0000 Received: from mail-lb0-f172.google.com (HELO mail-lb0-f172.google.com) (209.85.217.172) by server-7.tower-206.messagelabs.com with RC4-SHA encrypted SMTP; 24 Jul 2015 12:01:19 -0000 Received: by lbbzr7 with SMTP id zr7so13743855lbb.1 for ; Fri, 24 Jul 2015 05:01:19 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:sender:from:date:message-id:subject:to:content-type; bh=aKoFraDzp+8TwzsauDQW6Hy/ApFqvb1BdsyH2L7EZoc=; b=BJfjRnodGSJsG1MdUItslRMBGaDDDPfF01k/MY2Z/qf3EPO4oqPTMh5ffv0Cvslh2K R7Sfb4XUKl2m62UrTuGrh5YepCfEilDyfe+gEmdjU7Pn7qog8joujGZoWNwrcYdumOe5 zrrANb1+o74UqMGhUPylRNaFHxiuljRsxdms3hiPCXnma0xvmRuIr+sOzbWnCwvfN05z PdM/YkrIh1K3i2fGnfBsh8Cy4sYimh+El+859mnb18yuj+T9pgOBp0DXKqXLt/3WjpSV khGZWx6/nx1UK64fu3/eiDLw7XlBMZ3IbPK0OCNI4dC9fZw8VEWrfV8hQNAi/DFcjDb+ BhDA== X-Received: by 10.112.139.131 with SMTP id qy3mr13310621lbb.4.1437739278986; Fri, 24 Jul 2015 05:01:18 -0700 (PDT) MIME-Version: 1.0 Received: by 10.112.51.240 with HTTP; Fri, 24 Jul 2015 05:00:59 -0700 (PDT) From: Geoffroy Couprie Date: Fri, 24 Jul 2015 14:00:59 +0200 X-Google-Sender-Auth: LAcNGSe1rj_QP5wL2EtVFbQ6-r0 Message-ID: To: mirageos-devel@lists.xenproject.org Subject: [MirageOS-devel] Rust unikernels X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org Hello!

Hi Geoffroy, Have you thought about running Mirage on top of a minimal Rust OS kernel to start with? Then you could implement new drivers in Rust alongside existing Mirage code. As a garbage-collected language, OCaml can't be used to implement the very lowest levels of Mirage (e.g. malloc) and we currently use (my branch of) Mini-OS [1] for running as a unikernel on Xen. A common question is whether we could replace this C code with Rust. I'd be interested to help out if so - I've been meaning to take another look at Rust now it's stable. > A rough plan could be to take that project and: > - strenghten the rtl8139 driver If you target running under Xen, you only need to provide a simple Xen network driver, whatever the physical hardware is. Likewise for storage. This makes it easier to get started, and you'll support EC2, etc. > - write parsers and serializers for ARP, IP, TCP (it looks like > MirageOS does not even need DHCP, since the IP address is passed at > compilation time, is that right?). Mirage can use DHCP or static addresses. > This is something I am already > pushing for a parser combinators project I launched ( > https://github.com/Geal/nom ) > - building the API above that network stack > - the system can be monotask at first, but preemtive threading should > happen at some point If you have promises (and make all your low-level APIs non-blocking) then you can get a very long way without preemptive threading, although it would be good to have it eventually. > - a part of Rust standard library is already available, I do not know > how much is needed to support the use case of a HTTP server > - building monitoring tools inside the kernel When running under Xen, we share a trace buffer with dom0. This allows you to see what the system is doing, even if it is hung or crashed.

Hi Geoffroy, Have you thought about running Mirage on top of a minimal Rust OS kernel to start with? Then you could implement new drivers in Rust alongside existing Mirage code. As a garbage-collected language, OCaml can't be used to implement the very lowest levels of Mirage (e.g. malloc) and we currently use (my branch of) Mini-OS [1] for running as a unikernel on Xen. A common question is whether we could replace this C code with Rust. I'd be interested to help out if so - I've been meaning to take another look at Rust now it's stable. > A rough plan could be to take that project and: > - strenghten the rtl8139 driver If you target running under Xen, you only need to provide a simple Xen network driver, whatever the physical hardware is.

This is interesting, someone else proposed me that today too. This would be a good strategy to get something up and running quickly enough. Basically, Rust can build to a static library which can be linked to C code, but until there's a memory allocator available, things can be tricky. This is how RustOS does it: a small part written in C, which links to a Rust library that will handle the rest. The core parts of MiniOS could probably not be reimplemented right away, but drivers would be doable. From what I see, the first step is to communicate with the Xenbus and the Xenstore, right? Then have some ring buffers and a way for xen to signal that some data is available (I'm currently looking at netfront.c). > >> A rough plan could be to take that project and: >> - strenghten the rtl8139 driver > > If you target running under Xen, you only need to provide a simple Xen > network driver, whatever the physical hardware is.

The only driver needed for Mirage is the console driver, for early boot messages. Mirage has its own OCaml implementations of Xenbus and Xenstore, so replacing them isn't needed to get rid of the C. Much of Mini-OS is optional and unused (and it would be better to package the optional bits separately really).

This approach looks interesting. Every function in Mirage that might need to wait instead immediately returns a promise. e.g. the read function is defined as: val read: flow -> [`Ok of buffer | `Eof | `Error of error ] io (https://github.com/mirage/mirage/blob/d2d4502be0e53de16c915ac72dee008dcaf62991/types/V1.mli#L127) The type "X io" means "promise of an X" or "light-weight thread that will produce an X". Normally Mirage is used with the Lwt library, in which case "io" is defined to be "Lwt.t": https://github.com/mirage/mirage/blob/d2d4502be0e53de16c915ac72dee008dcaf62991/types/V1_LWT.mli#L25 Functions processing promises can be chained together in a similar way to non-promise functions, using the >>= operator. It's very useful, and most languages have something similar, though the names vary. A quick Google turned up this (incomplete-looking) Rust library: https://github.com/lucidd/rust-promise See https://mirage.io/wiki/tutorial-lwt for more details. >>> - a part of Rust standard library is already available, I do not know >>> how much is needed to support the use case of a HTTP server >>> - building monitoring tools inside the kernel >> >> When running under Xen, we share a trace buffer with dom0.

I'd probably start with the page allocator: https://github.com/talex5/mini-os/blob/master/mm.c /* * Initialise allocator, placing addresses [@min,@max] in free pool. * @min and @max are PHYSICAL addresses. */ static void init_page_allocator(unsigned long min, unsigned long max) This gets called early during boot with all the free RAM as the argument. It provides alloc_pages and free_pages to allocate from this range. Another possible starting place is the console driver: https://github.com/talex5/mini-os/blob/master/console/console.c That's a bit harder though because you're writing to memory shared with dom0, so you need to be careful about memory barriers and atomic operations. I assume Rust can handle this nicely? It would be fun to see how to use Rust's ownership types to ensure that other bits of code can't write to parts of a shared buffer that dom0 may be reading, etc. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Sat Jul 25 10:55:33 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Sat, 25 Jul 2015 10:55:33 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIx6v-0001FJ-Vo; Sat, 25 Jul 2015 10:55:21 +0000 Received: from mail6.bemta14.messagelabs.com ([193.109.254.103]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZIx6u-0001FE-OL for mirageos-devel@lists.xenproject.org; Sat, 25 Jul 2015 10:55:20 +0000 Received: from [193.109.254.147] by server-7.bemta-14.messagelabs.com id 96/D6-01469-81B63B55; Sat, 25 Jul 2015 10:55:20 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-16.tower-27.messagelabs.com!1437821717!27556709!1 X-Originating-IP: [209.85.216.45] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 27814 invoked from network); 25 Jul 2015 10:55:18 -0000 Received: from mail-vn0-f45.google.com (HELO mail-vn0-f45.google.com) (209.85.216.45) by server-16.tower-27.messagelabs.com with RC4-SHA encrypted SMTP; 25 Jul 2015 10:55:18 -0000 Received: by vnk197 with SMTP id 197so16904504vnk.3 for ; Sat, 25 Jul 2015 03:55:17 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=4NTgciniJuG51PhdXjfzf0AUgFeem5NCX/vkyIMYoDg=; b=MdA/05lc6/tIc4+f8Oh/TTtTFjH+AIKoMZ6ibW8sXZ0wGZeRWbH4DPu98PsIOnKwVZ WtXicZforwQ5wlRJCTG/fD4e4OI6HYsIQE+t6vdrdAVZroPgG2DS9pAe2EOMqVLbUFqi WY5K+vhdRvFa01zdd8g8gikhdtBrknuV+SdEpDzhtZLZj+u1BrPuWZ8YsfblIaE1mktU pf5/kAzRaVsa4y5GdOIUaOrIm2vzodjz70b4bIe2KNTtuuMw9ouxQOGAndRHMDVzbNTY xC1A4nRJh3NsDfhaArkNOMCkGwf8T+Enovx4fkI4QRN8lPkxR3DzjAvijng2dBmoXdV4 htXA== MIME-Version: 1.0 X-Received: by 10.52.114.196 with SMTP id ji4mr22463952vdb.24.1437821716813; Sat, 25 Jul 2015 03:55:16 -0700 (PDT) Received: by 10.31.65.144 with HTTP; Sat, 25 Jul 2015 03:55:16 -0700 (PDT) In-Reply-To: References: Date: Sat, 25 Jul 2015 11:55:16 +0100 Message-ID: From: Thomas Leonard To: Geoffroy Couprie Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] Rust unikernels X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 24 July 2015 at 23:28, Geoffroy Couprie wrote: > Hi Thomas, > > On Fri, Jul 24, 2015 at 3:02 PM, Thomas Leonard wrote: >> On 24 July 2015 at 13:00, Geoffroy Couprie wrote: >>> Hello! >>> >>> A chat on Twitter showed some interest in unikernels developed in >>> Rust, and I was pointed here for further discussion. >>> >>> First, I want to acknowledge the amazing work done on MirageOS by >>> everybody here.

Hardware is easiest to drive with callbacks, but traditional OS kernels go to a lot of trouble to present a blocking, synchronous API to userspace. Green threading libraries then have to mess around with OS threads to recover the asynchronous callback-based API. With Mini-OS, all that goes away. > Are multiple cores supported?

Our THEME OF THE MONTH: "The Reverse Yard Sale" For many of us in the northern hemisphere, this is the time of year when people sort through the things they own and put the things they no longer need into a yard sale. Well, instead of removing things we don't need, we want a reverse yard sale, where we add the things we *do* need.

Correction: Mini-OS's threading is also cooperative. However, it should be fairly easy to change it.

On x86, the interrupt handler uses the same stack as the rest of the code. Therefore, you must compile with the Rust equivalent of -mno-red-zone so Rust doesn't assume it can store things below the current stack pointer. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Tue Jul 28 08:29:37 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 28 Jul 2015 08:29:37 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZK0GO-000141-34; Tue, 28 Jul 2015 08:29:28 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZK0GM-00013p-7j for mirageos-devel@lists.xenproject.org; Tue, 28 Jul 2015 08:29:26 +0000 Received: from [85.158.137.68] by server-3.bemta-3.messagelabs.com id 16/79-01753-56D37B55; Tue, 28 Jul 2015 08:29:25 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-8.tower-31.messagelabs.com!1438072163!29842417!1 X-Originating-IP: [209.85.216.44] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 6.13.16; banners=-,-,- X-VirusChecked: Checked Received: (qmail 26567 invoked from network); 28 Jul 2015 08:29:23 -0000 Received: from mail-vn0-f44.google.com (HELO mail-vn0-f44.google.com) (209.85.216.44) by server-8.tower-31.messagelabs.com with RC4-SHA encrypted SMTP; 28 Jul 2015 08:29:23 -0000 Received: by vnaa140 with SMTP id a140so40336758vna.2 for ; Tue, 28 Jul 2015 01:29:22 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20120113; h=mime-version:in-reply-to:references:date:message-id:subject:from:to :cc:content-type; bh=R3sx1UEljhaxzdYaUM745GVGMp5tWWMqoKnzo4uBUy0=; b=nvcgAklKPulggMtMyuPgI3znunkV3ogappE+qu3Ad+m9Go1etNk9vaKJ50LDX9KRc4 S10JQw1i0WoV/MXEaSgmtx0mdl+BsJpc1oSzou6CnXVr+qbFOqT1jwcAe8SWm+npFO7B I2zXRiGFwzmKSiG1DuZww9XAs0jI8v5k7Qttgh+UZe5oV22BMkDNv9XIWddnRsjkyZnN KQA2sr/Iq2qGywh5GXnP84j04SggZ/DZnA7k1srbnD7RUDUzP7SrJLYNvWSDXupQjS3J zisSAxgU3ItXbCeKv4jlLEE1TfxyyCjhft/imvh6EVDZCXZUfpaxeTQybTdkzN53zJkZ tgYQ== MIME-Version: 1.0 X-Received: by 10.52.232.161 with SMTP id tp1mr18522823vdc.37.1438072162674; Tue, 28 Jul 2015 01:29:22 -0700 (PDT) Received: by 10.31.65.144 with HTTP; Tue, 28 Jul 2015 01:29:22 -0700 (PDT) In-Reply-To: References: Date: Tue, 28 Jul 2015 09:29:22 +0100 Message-ID: From: Thomas Leonard To: Geoffroy Couprie Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] Rust unikernels X-BeenThere: mirageos-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: Developer list for MirageOS List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 27 July 2015 at 15:54, Thomas Leonard wrote: > On 27 July 2015 at 09:36, Geoffroy Couprie wrote: >> Hi, >> >> On Sat, Jul 25, 2015 at 12:55 PM, Thomas Leonard wrote: >>> On 24 July 2015 at 23:28, Geoffroy Couprie wrote: >>>> Hi Thomas, >>>> >>>> On Fri, Jul 24, 2015 at 3:02 PM, Thomas Leonard wrote: >>>>> On 24 July 2015 at 13:00, Geoffroy Couprie wrote: >>>>>> Hello! >>>>>> >>>>>> A chat on Twitter showed some interest in unikernels developed in >>>>>> Rust, and I was pointed here for further discussion. >>>>>> >>>>>> First, I want to acknowledge the amazing work done on MirageOS by >>>>>> everybody here.

On x86, the interrupt handler uses the same stack as the rest of the code. Therefore, you must compile with the Rust equivalent of -mno-red-zone so Rust doesn't assume it can store things below the current stack pointer. -- Dr Thomas Leonard http://roscidus.com/blog/ GPG: DA98 25AE CAD0 8975 7CDA BD8E 0713 3F96 CA74 D8BA _______________________________________________ MirageOS-devel mailing list MirageOS-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel From mirageos-devel-bounces@lists.xenproject.org Tue Jul 28 17:28:33 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 28 Jul 2015 17:28:33 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZK8fw-0005cd-HS;

One other thing I should mention: Mini-OS runs in kernel mode a= nd can
be interrupted at any time. On x86, the interrupt handler uses the
same stack as the rest of the code. Therefore, you must compile with
the Rust equivalent of -mno-red-zone so Rust doesn't assume it can
store things below the current stack pointer.

I'm just starting to learn Rust, but I managed to create a simpl= e static lib and link it into a standalone Mini-OS build:
* build Rust from git with static musl libc support [1]
* compile libhello.a from [2]
* declare the Rust function as a= n extern in mini-os/kernel.c, call it from start_kernel()
* add -= L... -lhello to the Mini-OS linker flags
* make and run

Geoffroy, how does this compare to your approach?

To understand the interactions between Xen, Mini-OS, and Mi= rageOS, I found [3] and [4] useful starting points.

The zinc.rs [5] project, a Rust RTOS for A= RM, could provide some inspiration for modeling low-level operations in a t= ype-safe way.

One other thing I should mention: Mini-OS runs in kernel mode a= nd can
be interrupted at any time. On x86, the interrupt handler uses the
same stack as the rest of the code. Therefore, you must compile with
the Rust equivalent of -mno-red-zone so Rust doesn't assume it can
store things below the current stack pointer.

I'm just starting to learn Rust, but I managed to create a simpl= e static lib and link it into a standalone Mini-OS build:
* build Rust from git with static musl libc support [1]
* compile libhello.a from [2]
* declare the Rust function as a= n extern in mini-os/kernel.c, call it from start_kernel()
* add -= L... -lhello to the Mini-OS linker flags
* make and run

Geoffroy, how does this compare to your approach?

To understand the interactions between Xen, Mini-OS, and Mi= rageOS, I found [3] and [4] useful starting points.

The zinc.rs [5] project, a Rust RTOS for A= RM, could provide some inspiration for modeling low-level operations in a t= ype-safe way.

See my code here: https://github.com/Geal/mini-os/compare/master...rust Basically, I'm trying to replace some parts of Mini-OS with Rust code, as Thomas suggested.

Zinc looks great, and they do something that I was planning to: downloading the libcore part of Rust and linking to it directly. This is the easiest way to get Rust features as needed, without having too many dependencies.

This is nice, I did not know about musl usage. This may be a bit big=

We will need a Rust implementation of clients for Xenbus and Xen
events. Once code is running from start_kernel, the next step is
interacting with Xen's devices.

I&#= 39;ve started a learning exercise to see how much I can delete from Mini-OS= while still supporting Mirage.=C2=A0 Threading, POSIX emulation, HAVE_LIBC= , and all of the front/back devs can go (except console), and then I might = actually understand what's left.

Not knowing much about libcore = vs. libstd -- which parts of libstd are important to the task of replacing = C code in Mini-OS?

Thomas, what's mirage take on this?

See my code here: https://github.com/Gea= l/mini-os/compare/master...rust

Basically, I'm trying to replace some parts of Mini-OS with Rust code,<= br> as Thomas suggested. That way, we keep an architecture and a
bootloader that work well with Xen, and it can be tested right away
with Mirage.

We will need a Rust implementation of clients for Xenbus and Xen
events. Once code is running from start_kernel, the next step is
interacting with Xen's devices.

I&#= 39;ve started a learning exercise to see how much I can delete from Mini-OS= while still supporting Mirage.=C2=A0 Threading, POSIX emulation, HAVE_LIBC= , and all of the front/back devs can go (except console), and then I might = actually understand what's left.

Zinc looks great, and they do something that I was planning to:
downloading the libcore part of Rust and linking to it directly. This
is the easiest way to get Rust features as needed, without having too
many dependencies. And once there's a libcore, making a libstd gets
easier.

Not knowing much about libcore = vs. libstd -- which parts of libstd are important to the task of replacing = C code in Mini-OS?

Speaking of ARM, it would be in= teresting to see if the init_mm experiment runs on a Cubie:=C2=A0https://mirage.io/blog/= introducing-xen-minios-arm
