We don't entirely have an "owner" for this particular distribution yet, so I've got it on my queue to look at the next time I reinstall my Cubieboard. The three major components in there are the dom0 kernel, the base installation filesystem and the Xen/ARM hypervisor. Your patch touches the "difficult" part with a kernel modification, so we just need to decide if it's a Cubieboard-specific fork or not.

We don't entirely have an "owner" for this particular distribution yet, so I've got it on my queue to look at the next time I reinstall my Cubieboard. The three major components in there are the dom0 kernel, the base installation filesystem and the Xen/ARM hypervisor. Your patch touches the "difficult" part with a kernel modification, so we just need to decide if it's a Cubieboard-specific fork or not.

I think it's really important to distinguish between the mechanism uses for copying, and the APIs that are exposed at the Mirage API level. Some things to consider if the API bakes in copying: - stacking abstractions gets linearly more expensive, whereas with a zero-copy API references to memory can just be passed around through multiple depths. In Xen, grant references (which are handles to pages that contain the data) can be passed across multiple levels of backend/frontend drivers before the data itself is accessed. - copying is fast on modern x86, but other architectures with different memory/CPU tradeoffs will suffer. Those poor Cubieboards... - on the same point, memory bandwidth may be in surplus now, but is certainly not an infinite resource. On a modern NUMA system, you need to get "lines" of parallel bandwidth out of a multiqueue NIC, through the memory, via a CPU, and back out again. If the scheduler decides to cross NUMA domains, latency will rise and throughput will drop quite suddenly. I gave a talk about some measurement work we did on this at FOSDEM a few years ago: http://anil.recoil.org/talks/fosdem-io-2012.pdf http://fable.io (for raw data) - some application domains like proxies really benefit from a zero-copy API since they are passing through the bulk of the data untouched. Note that with a zero-copy API, the low-level mechanism we use to do the data transfer might still be a memory copy. This is indeed what Xen does at the device driver level, but it can always be shifted back to a page-table flip at any point. We're doing "ok" with zero-copy APIs in Mirage at the low-levels, but it falls apart slightly in the higher level libraries when regexps and other niceties are needed. Cohttp for example drops backs to strings, and it would be amazing to have it just take Cstruct vectors instead and process them in-place so that higher-level apps would all be able to do zero-copy instead. cheers, 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 Sun Nov 01 20:40:39 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Sun, 01 Nov 2015 20:40:39 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZszQT-0000Xy-O8; Sun, 01 Nov 2015 20:40:29 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZszQS-0000Xt-Kx for mirageos-devel@lists.xenproject.org; Sun, 01 Nov 2015 20:40:28 +0000 Received: from [85.158.137.68] by server-1.bemta-3.messagelabs.com id BF/20-01421-BB876365; Sun, 01 Nov 2015 20:40:27 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-7.tower-31.messagelabs.com!1446410424!31583!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: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 46535 invoked from network); 1 Nov 2015 20:40:24 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-7.tower-31.messagelabs.com with AES256-GCM-SHA384 encrypted SMTP; 1 Nov 2015 20:40:24 -0000 Received: by bark.recoil.org (OpenSMTPD) with ESMTPSA id 6087229b TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Sun, 1 Nov 2015 20:40:23 +0000 (GMT) Mime-Version: 1.0 (Mac OS X Mail 9.1 \(3096.5\)) From: Anil Madhavapeddy In-Reply-To: <5635F385.3040201@mehnert.org> Date: Sun, 1 Nov 2015 20:40:32 +0000 Message-Id: References: <5635F385.3040201@mehnert.org> To: Hannes Mehnert X-Mailer: Apple Mail (2.3096.5) Cc: mirageos-devel Subject: Re: [MirageOS-devel] copying packets 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 1 Nov 2015, at 11:12, Hannes Mehnert wrote: > > Hi (sorry if you already saw this), > > recently Luke Gorrie explained whether packet copies are expensive or > not -- https://github.com/SnabbCo/snabbswitch/issues/648 -- on modern > CPUs.

Specifically, if you were looking for more to do with this, I had been thinking about: 1. Adding this facility into [dog](https://github.com/samoht/dog) -- don't know what the status of dog is at the moment, but perhaps that would be a reasonable thing to do (@samoht?). 2. Some form of authentication/integrity protection for messages -- [RFC5425](http://tools.ietf.org/html/rfc5425) appears to be the place to start. (Also, I note that this was actually one my [Pioneer Projects](https://github.com/mirage/mirage-www/wiki/Pioneer-Projects), which you've done without any mentoring or assistance as far as I know -- so much for being a "beginner and non-professional programmer"! I guess I'll mark it mostly done on that list now :) -- 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 Tue Nov 03 10:31:43 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 03 Nov 2015 10:31:43 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZtYsI-00052J-S1; Tue, 03 Nov 2015 10:31:34 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZtYsH-00052D-E9 for mirageos-devel@lists.xenproject.org; Tue, 03 Nov 2015 10:31:33 +0000 Received: from [85.158.137.68] by server-6.bemta-3.messagelabs.com id E4/B1-29649-40D88365; Tue, 03 Nov 2015 10:31:32 +0000 X-Env-Sender: richard.mortier@gmail.com X-Msg-Ref: server-4.tower-31.messagelabs.com!1446546601!527930!1 X-Originating-IP: [209.85.212.180] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 25996 invoked from network); 3 Nov 2015 10:30:01 -0000 Received: from mail-wi0-f180.google.com (HELO mail-wi0-f180.google.com) (209.85.212.180) by server-4.tower-31.messagelabs.com with AES128-GCM-SHA256 encrypted SMTP; 3 Nov 2015 10:30:01 -0000 Received: by wikq8 with SMTP id q8so68484022wik.1 for ; Tue, 03 Nov 2015 02:30:00 -0800 (PST) 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=0AWkLf3z82nnwF7Phv2e5BWsdYRyPNF8t78QqQPjsCc=; b=F6dXEg/6z2F97j20uTWPyI+KPSpIHBf8O4JQvvfQwLr3uM6TwBaXMQAI5arAzqMhpw JKOJIQTBGHrZ549SrFQ6XBjiZSsfE85+jQsUZiL6lIn/m1ddsBGSZqL0es7vKnlD3vtd CBs/FgKuKt3T0P6I+4NGQekZbwbGdiyznyeFV1pAhseSOlXsylFQTF2VcIFs2HJqrgES os7dcZzAJWXMFrFU6ejsHUiUrB8l50u7XDjsNEvy3xWD5YoDylU8SVG11UnPTTPs0Ojl TrACudJOwCwPcdQEJcec2zaZzLP3j0vjnjUP7psYRq4a6b0S4NBego+mcZGxijMy0NJT 0fEA== X-Received: by 10.194.184.145 with SMTP id eu17mr27962111wjc.82.1446545026063; Tue, 03 Nov 2015 02:03:46 -0800 (PST) Received: from mail-wm0-f48.google.com (mail-wm0-f48.google.com.

Specifically, if you were looking for more to do with this, I had been thinking about: 1. Adding this facility into [dog](https://github.com/samoht/dog) -- don't know what the status of dog is at the moment, but perhaps that would be a reasonable thing to do (@samoht?). 2. Some form of authentication/integrity protection for messages -- [RFC5425](http://tools.ietf.org/html/rfc5425) appears to be the place to start. (Also, I note that this was actually one my [Pioneer Projects](https://github.com/mirage/mirage-www/wiki/Pioneer-Projects), which you've done without any mentoring or assistance as far as I know -- so much for being a "beginner and non-professional programmer"! I guess I'll mark it mostly done on that list now :) -- 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 Tue Nov 03 20:25:21 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 03 Nov 2015 20:25:21 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zti8k-0006O2-Vz; Tue, 03 Nov 2015 20:25:10 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zti8j-0006Nx-EG for mirageos-devel@lists.xenproject.org; Tue, 03 Nov 2015 20:25:09 +0000 Received: from [85.158.137.68] by server-1.bemta-3.messagelabs.com id 60/EA-13183-42819365; Tue, 03 Nov 2015 20:25:08 +0000 X-Env-Sender: stefanxe@gmx.net X-Msg-Ref: server-11.tower-31.messagelabs.com!1446582307!158860!1 X-Originating-IP: [212.227.17.20] X-SpamReason: No, hits=0.5 required=7.0 tests=sa_preprocessor: QmFkIElQOiAyMTIuMjI3LjE3LjIwID0+IDI4MDcx\n,sa_preprocessor: QmFkIElQOiAyMTIuMjI3LjE3LjIwID0+IDI4MDcx\n,BODY_RANDOM_LONG X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 64880 invoked from network); 3 Nov 2015 20:25:08 -0000 Received: from mout.gmx.net (HELO mout.gmx.net) (212.227.17.20) by server-11.tower-31.messagelabs.com with AES256-GCM-SHA384 encrypted SMTP; 3 Nov 2015 20:25:08 -0000 Received: from [192.168.178.45] ([93.220.69.149]) by mail.gmx.com (mrgmx102) with ESMTPSA (Nemesis) id 0LcVOE-1aLwCz1ZLC-00jq0U for ; Tue, 03 Nov 2015 21:25:07 +0100 To: mirageos-devel From: Stefan Xenon Message-ID: <56391822.5010009@gmx.net> Date: Tue, 3 Nov 2015 21:25:06 +0100 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Thunderbird/38.3.0 MIME-Version: 1.0 X-Provags-ID: V03:K0:oFa8IB9XrvSnaPMGWT8TMRneh1WY6SbA7TDvu7Ke1nUZfEsDNsa JX77pWpGR1ve07Ac6d+mYnk0ltI5taFreslpwLZsb3+bKurliZT7Txjc9u4Id3DWX5V6QsX 9Y7aiATLvbZFYEwg8NtDik2r/5EjBXFc5Udqmrnm7+ZY9zWgvWO9BaEnsJ0yEfisFUMZEw9 +VOMk60MCrc2jeEUtq0og== X-UI-Out-Filterresults: notjunk:1;V01:K0:3CvRQURypvY=:PXRmtELlPXAqAyCz72WWeG 70KwDd1e/Qur4qY2CX0WwJGTYN84KExE8xmQg32Qal6YBK6YZM+5hBtofDR6U/5TFZtdQ3CjK i9gtD4qfFCqyXhiCZJucC4CWuxUb3KRFRuHPz41rpVw4sQc0RIXET59xJ+Jd9YuJTBezfdaPL 8mgbF20DWu98lPxFAL3Jo/ljXvdgjNiyJtH+zqN1a4yJXkabZL9MZRgCV0X5WQSuva674rzw4 EKpYqb6v6BmH9RPjInQXByUDqU4yuXagbI0obylN67Yk4V/il58dP4QXsErF8kGCaqnTMgEAI CspzMPnks59UuagjpRrGsJTcR0Z9IsthQ6r+YMsEQKMVhrEZsgasuUC2JitZx+gqTalA5RlQt 66j6Kfzh/KEm4jNGbD7TP5wCGPhdAUhlEmOiTw2VJIHm0t70CKr4vHVr9I91Ml6NoYM7pexCl sSMyY+jCcxWkgssZ8XKSPlDyXzclkskvkRX0nYql7WpJRdP7gBy4HnDrC6/2Nnt669L2rszp7 hxuxufvtSqqDdFuAe+n2koPiVGixeFmVKSNcMJTuclDW/ubo9FHbe1xx51TIYy7uoWKQSOEyb cpBhImEOtcAo1Oj3wkoUNU2jKKsD+1J79AkyrS80MiI3ROlpCAtHgMkt4rk+kzAQWakoeknpw YB2DpuQQ3lEROVroW2J+TThGwZIfhsAuADFgvEX7RLjmhwmCwijeUjpPLK6CJ/KpZUey3nxb5 uKqFcN8Ezuq0dbr++DQrzi6hWCoffV43r4eCHHddX0OIkeBg4qo/b008CtTrRFF79fOr7catI OwD8XLb Subject: [MirageOS-devel] Security of XEN vs. Barebone 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 Hi! The recently fixed security bug in XEN brought attention to XEN's security quality. MirageOS is primarily based on XEN but also a barebone/rumpkernel setup seems to be an option (I'm not sure how mature it is but I leave this aside for the purpose of this discussion). MirageOS on top of XEN segregates domains which--for instance--protects the actual application against potentially vulnerable device drivers. On the other hand this protection is not 100% (e.g. security bugs) and XEN's own complexity increases the attack vector theoretically. A barebone setup has a smaller footprint and smaller attack vector but no segregation (AFAIK). Which setup would you recommend from a security point of view?

- HowTo talks for particular Unikernels:  Tell people how to get and b= uild a specific Unikernel.  Maybe demonstrate your favorite "Hell= o World" application.

- Use Cases for particular Unikernels:  Exactly what is your Unikernel= of choice suited for?  Why?  What attributes will grip users and= make them say, "I need to try that!"?

- Success Stories: Who is actually using your Unikernel and for what? = I have been asked multiple times for real world stories of Unikernels in a= ction.  This is your chance to make an impact on people hungry to hear= about some successes.

- War Stories: How did you build or employ a Unikernel?  What problems= did you face?  What solutions did you come up with?  Give the au= dience an account of some real world experiences to take home with them.
- Unikernel Tools: What tools have you used and/or developed to further the= use of Unikernels?  Tools for debugging, testing, instantiating, inte= grating... whatever.

We want talks to electrify a group of Unikernel novices and to encourage th= em to begin playing with Unikernels.

Interested?  Please let me know so we can give you an opportunity to m= ake some real noise at what could be the largest Unikernel user event ever = held!

If you think you might want in, drop me a line.

Thanks!

Running a single Mirage VM under Xen is almost certainly going to be at least as secure as running Mirage on bare metal. A Xen vulnerability may allow a compromised driver to attack the Mirage VM, but you'd still have the same or similar driver bugs on bare metal (and there with no protection at all). It may also allow another VM to attack the Mirage one, but if you don't mind running bare metal then you won't mind only running one Xen guest, either. > Disclaimer: I don't have experience coding MirageOS but follow the > project on a conceptual level. -- 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 Nov 04 16:51:42 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Wed, 04 Nov 2015 16:51:42 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zu1HY-00014X-OF; Wed, 04 Nov 2015 16:51:32 +0000 Received: from mail6.bemta14.messagelabs.com ([193.109.254.103]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zu1HX-00014O-5h for mirageos-devel@lists.xenproject.org; Wed, 04 Nov 2015 16:51:31 +0000 Received: from [193.109.254.147] by server-12.bemta-14.messagelabs.com id 2F/64-18744-2973A365; Wed, 04 Nov 2015 16:51:30 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-11.tower-27.messagelabs.com!1446655889!458386!1 X-Originating-IP: [209.85.160.174] X-SpamReason: No, hits=0.8 required=7.0 tests=BODY_RANDOM_LONG, RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 8557 invoked from network); 4 Nov 2015 16:51:29 -0000 Received: from mail-yk0-f174.google.com (HELO mail-yk0-f174.google.com) (209.85.160.174) by server-11.tower-27.messagelabs.com with AES128-GCM-SHA256 encrypted SMTP; 4 Nov 2015 16:51:29 -0000 Received: by ykba4 with SMTP id a4so82192716ykb.3 for ; Wed, 04 Nov 2015 08:51:28 -0800 (PST) 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=hwo+ZA5/38sxK2WcQXhrvwkryV+0jYWF1AtkT01oE3w=; b=bhhdx0BWhQv9KLxs/Q4dZLVdErYuGa3AxxFnivFHewwTeJGdW3VoqADhX1jPhsY7gE Yj13j6byJxxwZGilfOuUktExbmpT/FD4FL2cqRUfJItqTOEGL8Ztv2VszglMIPdsW9pr R9gyeznpeDrBMe2S5YuxoEM5huWgc8/Pyaxm4RrQhK4hdPNOO+q6H/4pGheeDrIbr3G+ ySsNr50TR2RuNDPznKVhk1CjeGxHMLBjdrdm9PjXMoJgyLGcyPq2phEDgD8VDV7PClXm GQfXW/lXLVj0gy+9nX8wSkrfYFigGJ5vDOeYtVuoI91WOnb4sOyczHoeLexSnHrliFmR Aewg== MIME-Version: 1.0 X-Received: by 10.31.49.10 with SMTP id x10mr2869880vkx.46.1446655888777; Wed, 04 Nov 2015 08:51:28 -0800 (PST) Received: by 10.31.63.66 with HTTP; Wed, 4 Nov 2015 08:51:28 -0800 (PST) In-Reply-To: <56391822.5010009@gmx.net> References: <56391822.5010009@gmx.net> Date: Wed, 4 Nov 2015 16:51:28 +0000 Message-ID: From: Thomas Leonard To: Stefan Xenon Cc: mirageos-devel Subject: Re: [MirageOS-devel] Security of XEN vs. Barebone 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 3 November 2015 at 20:25, Stefan Xenon wrote: > Hi! > The recently fixed security bug in XEN brought attention to XEN's > security quality.

Before I do this though, I wanted to let you know that the 2016 Developer Summit will most likely be in Berlin in October (I am in the process of finalising space, budget and contract details which will need to be approved by the Advisory Board). We do have two options for a Hackathon: China (either Shanghai, Hangzhou or Beijing - details TBC) and Cambridge, UK. We are still in the early planning phase and the budget for the Hackathon has not yet been approved. Do let me know of your preference, and I will see whether I can work with the vendor(s) who are willing to host the 2016 Hackathon and choose a location, which suits a majority of developers.

(Aside: Why did we decide we needed all past images in the current checkout of the deployment repos anyway?) -- 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 Tue Nov 10 11:13:06 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 10 Nov 2015 11:13:06 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zw6rI-0001dd-35;

raw device backends, although I'm not sure what the idea is there.

Hi Rupert,

The main thing is to implement Irmin's AO signature:

http= s://github.com/mirage/irmin/blob/4ccccb5d3117e4cc1ecff4a83cc508da59006423/l= ib/irmin.mli#L360

i.e. given a block of data, write it to disk and return its hash.
Given a hash, return the file data.

You could write the data sequentially to the disk and keep an index of
where everything has been stored.

=
I guess a first version of this could keep the whole index cached in m= emory for convenience and write updates to a log, flushing a copy to disk e= very now and again using double-buffering for example. See mirage-block-vol= ume[1]'s use of shared-block-ring[2] for an example of this. For bigger= amounts of data we'd probably want to keep the index on disk too -- pe= rhaps we should have some kind of on-disk b-tree library? I was wondering a= bout the format used by Linux's dm-thin driver[3]

Or, you coul= d perhaps use the file's
hash to decide where to store it. There's also irmin-chunk
(https://github.com/mirage/irmin-chunk) which says it might= help with
raw device backends, although I'm not sure what the idea is there.

http= s://github.com/mirage/irmin/blob/4ccccb5d3117e4cc1ecff4a83cc508da59006423/l= ib/irmin.mli#L360

i.e. given a block of data, write it to disk and return its hash.
Given a hash, return the file data.

You could write the data sequentially to the disk and keep an index of
where everything has been stored.

=
I guess a first version of this could keep the whole index cached in m= emory for convenience and write updates to a log, flushing a copy to disk e= very now and again using double-buffering for example. See mirage-block-vol= ume[1]'s use of shared-block-ring[2] for an example of this. For bigger= amounts of data we'd probably want to keep the index on disk too -- pe= rhaps we should have some kind of on-disk b-tree library? I was wondering a= bout the format used by Linux's dm-thin driver[3]

Or, you coul= d perhaps use the file's
hash to decide where to store it. There's also irmin-chunk
(https://github.com/mirage/irmin-chunk) which says it might= help with
raw device backends, although I'm not sure what the idea is there.

That's a very good idea and relatively easy to do, depending on which kind of syntax you want the parameter to be in. If that just strings, e.g. { "key": "ip", "value": "10.0.0.1" } that's easy. If you want the values to be JSON objects it'd be a bit harder / a bit more annoying / a bigger patch to functoria. Do you already have a syntax in mind?

That's a very good idea and relatively easy to do, depending on which kind of syntax you want the parameter to be in. If that just strings, e.g. { "key": "ip", "value": "10.0.0.1" } that's easy. If you want the values to be JSON objects it'd be a bit harder / a bit more annoying / a bigger patch to functoria. Do you already have a syntax in mind?

Hmm, it seems like that is built on top of = a few packages that don't exist any more to interface between Baardskee= rder and Mirage.

Do you think it's worth doing a simple B-= Tree implementation myself, or would it be better to try and build a new in= terface module for Mirage and Baardskeerder?

A B-Tree implemen= tation would certainly be good for the project write-up, but let me know wh= at you think.

There may be most of such a thing already I think -- Chris Greenhalgh
at Nottingham lashed something up a while ago based on Baardskeerder,

much earlier version of Mirage :)

Hmm, it seems like that is built on top of = a few packages that don't exist any more to interface between Baardskee= rder and Mirage.

Do you think it's worth doing a simple B-= Tree implementation myself, or would it be better to try and build a new in= terface module for Mirage and Baardskeerder?

A B-Tree implemen= tation would certainly be good for the project write-up, but let me know wh= at you think.

Hi Luis (+CC OPAM/Mirage lists as FYI),

I've uploaded OCaml 4.02.3 and OPAM 1.2.2 PPA builds for Wily to = Launchpad, where they're building in the experimental repository.  = Once that's completed (which takes a while due to the ARM builds), I = will move them over to the stable PPAs.

Note that OPAM 1.2.2 is already packaged up in Wily, so all that these = PPAs do is to upgrade the OCaml system version to 4.02.3 (from = 4.02.1).

Since it's for a project, take all of this with a pinch = of salt: (random thoughts follow)

A simple b-tree on disk would probably be much like an in-he= ap b-tree, except the nodes would be naturally wider and you would also nee= d to track and reclaim free blocks (which the GC would normally do for you)= . You could do something really minimal at first (eg allocate by pointer bu= mp, no deallocation) and then perhaps do a big stop-the-world thing (like f= sck) and, if there's enough time, try something more incremental. Perha= ps the "root" block would reference the tree root+a free list? Yo= u could also analyse or profile the costs in terms of disk seeks?

If it were me, I'd be happier in a project implementing = a relatively pure algorithm than binding together much bigger things (like = baardskeerder) which were designed for something much bigger (eg clustering= ?) and where impedance mismatches are more likely.

A B-Tree implementation would certai= nly be good for the project write-up, but let me know what you think.

There may be most of such a thing already I think -- Chris Greenhalgh
at Nottingham lashed something up a while ago based on Baardskeerder,
see https://github.com/cgreenhalgh/ocaml-btree (though= based on a much
much earlier version of Mirage :)

Since it's for a project, take all of this with a pinch = of salt: (random thoughts follow)

A simple b-tree on disk would probably be much like an in-he= ap b-tree, except the nodes would be naturally wider and you would also nee= d to track and reclaim free blocks (which the GC would normally do for you)= . You could do something really minimal at first (eg allocate by pointer bu= mp, no deallocation) and then perhaps do a big stop-the-world thing (like f= sck) and, if there's enough time, try something more incremental. Perha= ps the "root" block would reference the tree root+a free list? Yo= u could also analyse or profile the costs in terms of disk seeks?

If it were me, I'd be happier in a project implementing = a relatively pure algorithm than binding together much bigger things (like = baardskeerder) which were designed for something much bigger (eg clustering= ?) and where impedance mismatches are more likely.

Do you think it's worth doing a simple B-Tree implementation= myself, or would it be better to try and build a new interface module for = Mirage and Baardskeerder?

A B-Tree implementation would certai= nly be good for the project write-up, but let me know what you think.

Simple and in-memory is (surely!) still good to start with though!

There may be most of such a thing already I think -- Chris Greenhalgh
at Nottingham lashed something up a while ago based on Baardskeerder,
see https://github.com/cgreenhalgh/ocaml-btree (though= based on a much
much earlier version of Mirage :)

Hi all,

We are preparing the next release of the mirage tool, which will bring nice= enhancement on configuration and runtime command-line parameters developed= by Gabriel Radanne this summer. If you want to test it you can do:

=C2=A0 =C2=A0 opam pin add functoria https://github.com/mirag= e/functoria.git
=C2=A0 =C2=A0 opam pin add mirage --dev

then you can test the result on the functoria branch of Drup's mirage-s= keleton:

=C2=A0 =C2=A0 git clone -b functoria https://github.com/D= rup/mirage-skeleton.git
=C2=A0 =C2=A0 cd mirage-skeleton/network
=C2=A0 =C2=A0 mirage describe
=C2=A0 =C2=A0 mirage configure --help # see the configuration time options<= br> =C2=A0 =C2=A0 make
=C2=A0 =C2=A0./mir-network --help # see the runtime options

You can play with the command-line options and see how the command-time opt= ions can influence the presence and default values of runtime options.

Early feedback=C2=A0 (good or bad :p) is much appreciated!

Enjoy,
Thomas, on behalf on the merry MirageOS crew

Just wanted to give a general thumbs up for Functoria, I a= dded another module to mirage-types and it was a really simple experience t= o get it into the code generation.

Hi all,

We are preparing the next release of the mirage tool, which will bring nice= enhancement on configuration and runtime command-line parameters developed= by Gabriel Radanne this summer. If you want to test it you can do:

=C2=A0 =C2=A0 opam pin add functoria https://github.com/mirag= e/functoria.git
=C2=A0 =C2=A0 opam pin add mirage --dev

then you can test the result on the functoria branch of Drup's mirage-s= keleton:

=C2=A0 =C2=A0 git clone -b functoria https://github.com/D= rup/mirage-skeleton.git
=C2=A0 =C2=A0 cd mirage-skeleton/network
=C2=A0 =C2=A0 mirage describe
=C2=A0 =C2=A0 mirage configure --help # see the configuration time options<= br> =C2=A0 =C2=A0 make
=C2=A0 =C2=A0./mir-network --help # see the runtime options

You can play with the command-line options and see how the command-time opt= ions can influence the presence and default values of runtime options.

Early feedback=C2=A0 (good or bad :p) is much appreciated!

Enjoy,
Thomas, on behalf on the merry MirageOS crew

The main new feature in this version is the ability to have optional backends to manage unikernels. Previously all backends where compiled in by default, but this didn't work well as not all backends would be available on every platform. With this change Jitsu can be installed on OS X again (with libvirt) and on older Ubuntu's (without xenctrl). To make it easier to install Jitsu with a specific backend I've added virtual packages for jitsu-libxl, jitsu-libvirt and jitsu-xapi in opam. Backends can also be installed manually and installing multiple backends will enable all of them. Changes since the last opam release (v0.2.0): - Support modular backends (xenctrl, libvirt and xen-api-client). Only available backends are compiled in by default. - Add virtual packages for jitsu-libvirt, jitsu-libxl, jitsu-xapi - Add/fix support for multiple DNS entries per VM - Update README with links to paper, recent blog posts and new installation instructions - Add VERSION file to track version in builds and releases - Support xenctrl > 0.9.26 - Support xen-api-client > 0.9.8 - Update storage backend to support latest Irmin API (>= 0.10.0) The full change log is available here [2]. 1. https://github.com/mirage/jitsu 2. https://github.com/mirage/jitsu/blob/master/CHANGES.md -- Magnus _______________________________________________ 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 Nov 12 12:19:52 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 12 Nov 2015 12:19:52 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zwqqu-0001Yl-83; Thu, 12 Nov 2015 12:19:44 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zwqqt-0001Yf-Hc for mirageos-devel@lists.xenproject.org; Thu, 12 Nov 2015 12:19:43 +0000 Received: from [85.158.139.211] by server-6.bemta-5.messagelabs.com id 93/50-22089-ED384465; Thu, 12 Nov 2015 12:19:42 +0000 X-Env-Sender: magnus@v0.no X-Msg-Ref: server-11.tower-206.messagelabs.com!1447330781!3076525!1 X-Originating-IP: [66.111.4.28] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 32736 invoked from network); 12 Nov 2015 12:19:42 -0000 Received: from out4-smtp.messagingengine.com (HELO out4-smtp.messagingengine.com) (66.111.4.28) by server-11.tower-206.messagelabs.com with DHE-RSA-AES256-GCM-SHA384 encrypted SMTP; 12 Nov 2015 12:19:42 -0000 Received: from compute4.internal (compute4.nyi.internal [10.202.2.44]) by mailout.nyi.internal (Postfix) with ESMTP id 55EFE20B93 for ; Thu, 12 Nov 2015 07:19:41 -0500 (EST) Received: from web6 ([10.202.2.216]) by compute4.internal (MEProxy); Thu, 12 Nov 2015 07:19:41 -0500 DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d=v0.no; h= content-transfer-encoding:content-type:date:from:message-id :mime-version:subject:to:x-sasl-enc:x-sasl-enc; s=mesmtp; bh=jZ7 L2UK83GhclVEPST720gG+3Eo=; b=XYwnV2Erlyi515pEdh4ytCkfWYxaBUutiXV YYKms3eoUPdJBwbyNfyZDcnWgQYrZTLAzNWCT53yqsrVfCIcGtkTijFg+qQ0nAry n/zX5of3ir2FQ9PjEgkSNZ4+tHOAV85elIy5Y7Hdd5+DKnhtYCXg542gIbexYtXU pbb9aEMs= DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d= messagingengine.com; h=content-transfer-encoding:content-type :date:from:message-id:mime-version:subject:to:x-sasl-enc :x-sasl-enc; s=smtpout; bh=jZ7L2UK83GhclVEPST720gG+3Eo=; b=lANcb Z4XdagsNNjwn4sgg+bW6VBCOpG6HTuE4qU7PVCGhcAJYbuQjO96NKU+coXh8QYxN sv/VybqUWns7PbdkiaQYoTQ7+jBygAvjQlYiIw9jBJEcj7ReZ1VLIaaPbK5iJzbU yiSAlVM0gqqsaz+rnbf2sssfEsZO1AQMS+U+rM= Received: by web6.nyi.internal (Postfix, from userid 99) id 0E8284C383; Thu, 12 Nov 2015 07:19:41 -0500 (EST) Message-Id: <1447330781.2732957.437007329.46557F96@webmail.messagingengine.com> X-Sasl-Enc: bUQmyLR5PVvaJW6/6cFBioqSTCh63CvR8RNlbngoKib4 1447330781 From: Magnus Skjegstad To: mirageos-devel@lists.xenproject.org MIME-Version: 1.0 X-Mailer: MessagingEngine.com Webmail Interface - ajax-643af86c Date: Thu, 12 Nov 2015 13:19:41 +0100 Subject: [MirageOS-devel] [ANN] Jitsu 0.3.0 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 Hi all, I've just released version 0.3.0 of Jitsu[1] in opam.

Only available backends are compiled in by default. - Add virtual packages for jitsu-libvirt, jitsu-libxl, jitsu-xapi - Add/fix support for multiple DNS entries per VM - Update README with links to paper, recent blog posts and new installation instructions - Add VERSION file to track version in builds and releases - Support xenctrl > 0.9.26 - Support xen-api-client > 0.9.8 - Update storage backend to support latest Irmin API (>= 0.10.0) The full change log is available here [2]. 1. https://github.com/mirage/jitsu 2. https://github.com/mirage/jitsu/blob/master/CHANGES.md -- Magnus _______________________________________________ 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 Nov 12 13:42:32 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 12 Nov 2015 13:42:32 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zws8v-0007kn-LV; Thu, 12 Nov 2015 13:42:25 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Zws8u-0007kc-Bd for mirageos-devel@lists.xenproject.org; Thu, 12 Nov 2015 13:42:24 +0000 Received: from [85.158.137.68] by server-4.bemta-3.messagelabs.com id 0A/32-09570-F3794465; Thu, 12 Nov 2015 13:42:23 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-11.tower-31.messagelabs.com!1447335742!2514170!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.5 required=7.0 tests=MAILTO_TO_SPAM_ADDR, RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 1035 invoked from network); 12 Nov 2015 13:42:22 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-11.tower-31.messagelabs.com with DHE-RSA-AES256-GCM-SHA384 encrypted SMTP; 12 Nov 2015 13:42:22 -0000 Received: by bark.recoil.org (OpenSMTPD) with ESMTPSA id 1918d5d1 TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Thu, 12 Nov 2015 13:42:21 +0000 (GMT) Mime-Version: 1.0 (Mac OS X Mail 9.1 \(3096.5\)) From: Anil Madhavapeddy In-Reply-To: <7C85D096-40CA-42DD-B408-0EC9E066DAE8@cam.ac.uk> Date: Thu, 12 Nov 2015 13:42:21 +0000 Message-Id: <5C54DF5F-52FE-45D1-A885-CE4FF3B6DF49@recoil.org> References: <20151109113322.GY3006@annexia.org> <75B08AC5-B781-4998-9A72-C5A8C214BD2F@recoil.org> <396AD0C1-31B4-4DA2-BF09-421AB8DFD455@recoil.org> <5643D916.6040205@luminar.eu.org> <7C85D096-40CA-42DD-B408-0EC9E066DAE8@cam.ac.uk> To: Amir M Chaudhry X-Mailer: Apple Mail (2.3096.5) Cc: mirageos-devel@lists.xenproject.org Subject: Re: [MirageOS-devel] Hardware choices for ARM64 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="windows-1252" Content-Transfer-Encoding: quoted-printable Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org > On 12 Nov 2015, at 11:43, Amir Chaudhry wrote: > = >> = >> On 12 Nov 2015, at 00:11, Vincent Bernardoff wrote: >> = >> On 09/11/2015 15:21, Anil Madhavapeddy wrote: >>> Just fyi, I also got another off-list reply pointing to: >>> = >>>> The gigabyte MP30-AR0 boards are nice and very affordable: >>>> = >>>> http://b2b.gigabyte.com/products/product-page.aspx?pid=3D5422#ov >>>> = >>>> includes the X-gene 1 processor.

Hi Luis (+CC OPAM/Mirage lists as = FYI),

I've uploaded OCaml 4.02.3 and OPAM 1.2.2 PPA builds for Wily to Launch= pad, where they're building in the experimental repository.=C2=A0 Once = that's completed (which takes a while due to the ARM builds), I will mo= ve them over to the stable PPAs.

Note that OPAM 1.2.2 is already packaged up in Wily, so all that these PPAs= do is to upgrade the OCaml system version to 4.02.3 (from 4.02.1).

Anil

I've uploaded OCaml 4.02.3 and OPAM 1.2.2 PPA builds for Wily to Launch= pad, where they're building in the experimental repository.=C2=A0 Once = that's completed (which takes a while due to the ARM builds), I will mo= ve them over to the stable PPAs.

Note that OPAM 1.2.2 is already packaged up in Wily, so all that these PPAs= do is to upgrade the OCaml system version to 4.02.3 (from 4.02.1).

Anil

Obviously Cubieboard2 works but I couldn't find information about other supported devices. In particular I'm interested in faster devices than the Cubieboard2. Could anybody list other working boards and summarize the requirements to look for? Thanks a lot.

The goal is that the protocol logic is independent of any side effects, but has an explicit API what action the effectful client should do (which a test harness could also check for, instead of putting the bytes onto the wire). I think the design space of software implementations is very thinly populated, and we should try out more approaches.

I think protocols have 3 APIs - there's "lower le= vel" i/o, there's "upper level" i/o, and there's env= ironmental (timers, resource exhausation or relief, lie out of buffer or he= re's some more) - the APIs can be refined a bit (init, config, and fire= , read/write)

believe it or not, the OSI model is quite = nice in that it describes the abstraction that a protocol provides (the hig= her level API offers a service, the lower level one is a use of a service, = the thing in between, the state and state machine, implement something that= turns the lower one into the, hopefully, simpler upper one.

=
the canonical example in the internet word is the reliable, flow= controlled transport protocol....running over the unreliable, uncontrolled= internet protocol....

so the sock stream service = is effectively the pipe emulation, to make everything above tcp allegedly a= s simple as writing programmes that talk to infinite files (unix style)
and the datagram service below is unexpected, unreliable, and unorde= red messages/packets
and the machinery in the middle, your state = machine, plus the api to resource management (most crucially timers), makes= one out of the other...

the simplest mapping onto= an implementation is to build the system as 3 cooperating threads, sharing= 1 state structure (atomically:) to structure how they coordinate..but ther= e are lots of other ways one could build that (including just a single big = wait()/select()/polling:)

the other bit of the API= to the lower level is what you mostly put in yr bog article - which is pac= ket parsing (and construction) - my personal take on this is that this ough= t to be an easy part of the problem, but I am biased, coz I think only ad p= eople would use ASN.1 and BER for any real world protocol, and the design o= f TCP and IP (without options) was cool because for a C compiler and a PDP-= 11 (16 bit) or vax (32 bit) it was obvious what the headers looked like (th= ere's 20 bytes and fields are all processable in registers, and only a = mad c-compiler writer would not map a c struct defined correctly into the r= ight thing in memory (and therefore also on the wire, given a non-mad NIC),= with the only glotch being the introduction of htons/htonl coz of DEC vax = (and later intel) being barking mad about byte significance across words (a= ka unsigned ints)

I think protocols have 3 APIs - there's "lower le= vel" i/o, there's "upper level" i/o, and there's env= ironmental (timers, resource exhausation or relief, lie out of buffer or he= re's some more) - the APIs can be refined a bit (init, config, and fire= , read/write)

believe it or not, the OSI model is quite = nice in that it describes the abstraction that a protocol provides (the hig= her level API offers a service, the lower level one is a use of a service, = the thing in between, the state and state machine, implement something that= turns the lower one into the, hopefully, simpler upper one.

the canonical example in the internet word is the reliable, flow= controlled transport protocol....running over the unreliable, uncontrolled= internet protocol....

so the sock stream service = is effectively the pipe emulation, to make everything above tcp allegedly a= s simple as writing programmes that talk to infinite files (unix style)
and the datagram service below is unexpected, unreliable, and unorde= red messages/packets
and the machinery in the middle, your state = machine, plus the api to resource management (most crucially timers), makes= one out of the other...

the simplest mapping onto= an implementation is to build the system as 3 cooperating threads, sharing= 1 state structure (atomically:) to structure how they coordinate..but ther= e are lots of other ways one could build that (including just a single big = wait()/select()/polling:)

the other bit of the API= to the lower level is what you mostly put in yr bog article - which is pac= ket parsing (and construction) - my personal take on this is that this ough= t to be an easy part of the problem, but I am biased, coz I think only ad p= eople would use ASN.1 and BER for any real world protocol, and the design o= f TCP and IP (without options) was cool because for a C compiler and a PDP-= 11 (16 bit) or vax (32 bit) it was obvious what the headers looked like (th= ere's 20 bytes and fields are all processable in registers, and only a = mad c-compiler writer would not map a c struct defined correctly into the r= ight thing in memory (and therefore also on the wire, given a non-mad NIC),= with the only glotch being the introduction of htons/htonl coz of DEC vax = (and later intel) being barking mad about byte significance across words (a= ka unsigned ints)

Hey,

I just revived a draft on how to write protocols in a purely functional
way.=C2=A0 The goal is that the protocol logic is independent of any side effects, but has an explicit API what action the effectful client should do (which a test harness could also check for, instead of putting the
bytes onto the wire).

I think the design space of software implementations is very thinly
populated, and we should try out more approaches.=C2=A0 The draft is based = on
experience developing TLS with David (which was my first OCaml project), and OTR, but also experience from implementing TCP/IP in Dylan (a LISP
dialect) back in 2005 (retrospectively I can find shortcomings of that
approach much easier).

I'm eager to discuss it in further detail on this list (I'm pretty = sure
it is incomplete and partially wrong).

many modularisation abstractions can be overused - either = coz excess abstraction is done (there just aren't that many really diff= erent types/cases of use) or coz it turns into an efficiency killer (or bot= h) - this showed up in a big open source router project called Xorp at berk= eley where they made the dubious decision to use C++ - talk to people about= the nightmare of coding conventions they ended up with - dunno if it was w= ritten up anywhere but people that tried re-purposing the code (a primary t= est of the appropriateness of an abstraction or modular decision) ended up = re-writing it....oops (and I mean that most linguistically)

I may have phrased it wrongly: my intention is that you shouldn'= t
abstract over all potential modules (such as IO), but rather provide a
simple interface (exposing intended actions).

I personally find the cohttp and TCP/IP code hard to read due to the use of lots of functors / module abstractions, which are not necessarily
needed IMHO.

Feedback welcome, Thanks for writing it -- I've found it useful to refer to while refactoring https://github.com/mor1/ocaml-tftp, which I believe is now a lot cleaner than it was as a result :) -- 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 Sat Nov 14 16:02:12 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Sat, 14 Nov 2015 16:02:12 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZxdHG-0001QU-EE; Sat, 14 Nov 2015 16:02:10 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1ZxdHF-0001QL-2O for mirageos-devel@lists.xenproject.org; Sat, 14 Nov 2015 16:02:09 +0000 Received: from [85.158.137.68] by server-10.bemta-3.messagelabs.com id 91/C0-02804-00B57465; Sat, 14 Nov 2015 16:02:08 +0000 X-Env-Sender: richard.mortier@gmail.com X-Msg-Ref: server-16.tower-31.messagelabs.com!1447516927!3108812!1 X-Originating-IP: [74.125.82.52] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 22079 invoked from network); 14 Nov 2015 16:02:07 -0000 Received: from mail-wm0-f52.google.com (HELO mail-wm0-f52.google.com) (74.125.82.52) by server-16.tower-31.messagelabs.com with AES128-GCM-SHA256 encrypted SMTP; 14 Nov 2015 16:02:07 -0000 Received: by wmdw130 with SMTP id w130so63089164wmd.0 for ; Sat, 14 Nov 2015 08:02:07 -0800 (PST) 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:content-transfer-encoding; bh=2up3Kp9twvO7qvebtFsBTS9Orec1g+FElo2QjBeBtQE=; b=Mr1lsiP3ogmfB33zyDBhCD+dVyFuZwcSaXX98XhBMvyVC3bZYAf+VWvREaQThUiu4o +RzorKcclKtZXdNTx81+kxpjD9xt/0OzPLDNks1RKcfcplze3dFsTMsiDw/WshxPZFm5 1AMyiVAS7cYxXPTXI87+uqTvsgyTfaMySSGIXXRdYIvBr/gza1mjCSbOJxQnVM6OldlD 943Y1SboD/JbTTlNoDHLb6kRlAyiJ13LZYCJz+vNLYPbP+i7bdQGM2AaOmMOKcuX1z1G znI2dPMHeDiKYJ7uWcinWW0b3jQD326LIpyWXctdQOhfCLfA3AFj+tQa86zPRXRGnjJl myDg== X-Received: by 10.28.146.82 with SMTP id u79mr9391218wmd.96.1447516927305; Sat, 14 Nov 2015 08:02:07 -0800 (PST) Received: from mail-wm0-f47.google.com (mail-wm0-f47.google.com.

Not only they are not needed, it's also the wrong way of handlin= g this as it is well known that factoring out module dependencies as functo= rs doesn't scale in practice. The question to ask yourself for using a = functor is: do I need multiple instances of the functor in *the same progra= m* =E2=80=94 good examples: {Map,Set}.Make.

One of the design goals of Cohttp was to allow multiple, completely = independent network stacks (including sockets and direct stacks) to run wit= hin the same program.=C2=A0 It has also been fairly successful at getting t= hird parties to port the appropriate part of the interface that they need t= o different backends, such as Andy Ray doing a JavaScript version that uses= only the higher-level parts of the stack.

It's also worth noting that you can even use Cohttp_async and Cohttp_lw= t within the same program, as Jeremie Diminio did an Lwt-on-Async adapter.= =C2=A0 This isn't necessarily advisable, but it is possible :-)=C2=A0 A= gain, this will all be consolidated when we have a more standard concurrenc= y story within OCaml, but functorising IO wasn't an entirely terrible d= ecision.

Where functors fall over is the terrible documentation and tooling assistan= ce when faced with using one, and this is being addressed by codoc and Merl= in.

> Other than that the document feels like unstructured, poorly written [= 1], random rumblings.

Grumpy day, eh?=C2=A0 I thought it was an excellent first cut that l= aid out some of the issues to consider for beginners wishing to build their= own protocol.=C2=A0 We can iterate on it, which is Hannes' intention f= or sending it to this list.

One of the design goals of Cohttp was to allow multiple, completely = independent network stacks (including sockets and direct stacks) to run wit= hin the same program.=C2=A0 It has also been fairly successful at getting t= hird parties to port the appropriate part of the interface that they need t= o different backends, such as Andy Ray doing a JavaScript version that uses= only the higher-level parts of the stack.

It's also worth noting that you can even use Cohttp_async and Cohttp_lw= t within the same program, as Jeremie Diminio did an Lwt-on-Async adapter.= =C2=A0 This isn't necessarily advisable, but it is possible :-)=C2=A0 A= gain, this will all be consolidated when we have a more standard concurrenc= y story within OCaml, but functorising IO wasn't an entirely terrible d= ecision.

Where functors fall over is the terrible documentation and tooling assistan= ce when faced with using one, and this is being addressed by codoc and Merl= in.

Grumpy day, eh?=C2=A0 I thought it was an excellent first cut that l= aid out some of the issues to consider for beginners wishing to build their= own protocol.=C2=A0 We can iterate on it, which is Hannes' intention f= or sending it to this list.

dif= ferent abstractions have
different cognitive overhead,
different time overhead and a
different runtime overhead -

we're driven by tradeoffs
in systems programming goals and
in a real world project resources (human programmer time) which
may mean we choose something that takes
less time to write, and is less generic -
it can be made more generic later (with more work)
we might choose something that has a steeper learning curve
(sockets won as an abstraction of internet protocols over other
APIs/services because=C2=A0 they were easier to learn - they are a pain in<= br> other regards) -

and (as discussed and thanks to jeremy et al for pointers)
some language features have more or less compile v. runtime - even at
the trivial function level, inlining might work - templates in C++
looked good at the time, but require peppering the declartion with all
sorts of quid pro quos about the type assumptions (hard to write,
hard to read) but compile to=C2=A0 faster code than functors (an old
polymorphic type systems design tradeoff etc etc...

more readable doesn't mean more writeable;)

Forgot to add....language tools change (especially at module= level, as per c++ or OCaml toolchains) and contributor skill levels grow, = so all choice of abstraction level is an ephemeral compromise...

dif= ferent abstractions have
different cognitive overhead,

different runtime overhead -

we're driven by tradeoffs
in systems programming goals and
in a real world project resources (human programmer time) which
may mean we choose something that takes
less time to write, and is less generic -
it can be made more generic later (with more work)
we might choose something that has a steeper learning curve
(sockets won as an abstraction of internet protocols over other
APIs/services because=C2=A0 they were easier to learn - they are a pain in<= br> other regards) -

and (as discussed and thanks to jeremy et al for pointers)
some language features have more or less compile v. runtime - even at
the trivial function level, inlining might work - templates in C++
looked good at the time, but require peppering the declartion with all
sorts of quid pro quos about the type assumptions (hard to write,
hard to read) but compile to=C2=A0 faster code than functors (an old
polymorphic type systems design tradeoff etc etc...

more readable doesn't mean more writeable;)

Hi,
 
Questions regarding changes in Irmin 0.10.0:
 
1- Is there any equivalence for "Irmin.watch_tags" in the previous releases?
2- This is somehow related to the first question, that is how to create a store similar to "Store.of_head config task head" (for instance, from the heads that watch_tag sends to the callback function) in the older versions.
 
Thanks.

The problem with doing an additional redundant verification in Mirage is that when two local VMs are talking then the Xen driver, which has offered checksum offload, does not do any actual checksum computation. So all packets arrive with invalid checksums. The particular call to the null function is there just as a marker that this is where it should be checked. A proper solution would be to correctly process the offload offers, which mirage doesn't, AFAIK. Clearly if the driver offers offload then checksum computation should not be done on the way out or verification on the way in, else it should. There is a complication that checksum offload can be turned on or off midstream so it may have to change per packet. A good project for someone interested.

The short answer is that the checksum is assumed to have b= een verified before the packet is handed to the Mirage stack. =C2=A0
The problem with doing an additional redundant verification in= Mirage is that when two local VMs are talking then the Xen driver, which h= as offered checksum offload, does not do any actual checksum computation.= =C2=A0 So all packets arrive with invalid checksums.

The= particular call to the null function is there just as a marker that this i= s where it should be checked.

A proper solut= ion would be to correctly process the offload offers, which mirage doesn= 9;t, AFAIK.=C2=A0 Clearly if the driver offers offload then checksum comput= ation should not be done on the way out or verification on the way in, else= it should.=C2=A0 There is a complication that checksum offload can be turn= ed on or off midstream so it may have to change per packet.

Specifically, https://github.com/mi= rage/mirage-tcpip/blob/master/tcp/pcb.ml#L99
appears to define `verify_checksum` to always return `true`; but it is
then called at https://github.com/= mirage/mirage-tcpip/blob/master/tcp/pcb.ml#L510
in the `input` function in a way that probably expects checksums to
have actually been verified.

Which seems rather odd -- am I missing something?

There is discussion on the qubes mailing list at the moment about
using unikernel VMs:

=C2=A0 https://groups.google.com/foru= m/#!topic/qubes-users/h03-1hiNMCc

I've written a simple test unikernel [1] that supports Qubes' qrexe= c
protocol. This allows other domains to send command requests to the
VM. If approved by the dom0 policy, a two-way channel (stdin/stdout)
is established between the requesting VM and the unikernel. qrexec is
built on top of vchan, which was easy to support thanks to David
Scott's ocaml-vchan library.

A smal= l nitpick: although I've written a lot of vchan code recently, the orig= inal fully-working version was by Vincent Bernadoff (vbmithr on github)

Apart from that, awesome -- makes me want to buy a PC= laptop and install Qubes :-)

Cheers,
Da= ve
=C2=A0

I've also written a tool [2] to let you upload unikernels built in an AppVM to dom0 and run them easily.

For example:

$ mirage configure --xen
$ make
$ test-mirage mir-qubes-test.xen
Waiting for 'Ready'... OK
Uploading 'mir-qubes-test.xen' (4187256 bytes)
Waiting for 'Booting'... OK
--> Creating volatile image: /var/lib/qubes/appvms/mirage-test/volatile.= img...
--> Loading the VM (type =3D AppVM)...
--> Starting Qubes DB...
--> Setting Qubes DB info for the VM...
--> Updating firewall rules...
--> Starting the VM...
--> Starting the qrexec daemon...

It currently offers "echo" and "quit" services. e.g. fr= om dom0:

Hi user! Please enter a string:
Hello
You wrote "Hello". Bye.

If anyone is interested in helping out, let me know! I've added a
pioneer project [3] to replace their existing FirewallVM with a Mirage
unikernel, as one possibility. We also need basic QubesDB support and
some kind of GUId so that Qubes will believe the VM has started (it
assumes every VM provides a GUI currently).

There is discussion on the qubes mailing list at the moment about
using unikernel VMs:

=C2=A0 https://groups.google.com/foru= m/#!topic/qubes-users/h03-1hiNMCc

I've written a simple test unikernel [1] that supports Qubes' qrexe= c
protocol. This allows other domains to send command requests to the
VM. If approved by the dom0 policy, a two-way channel (stdin/stdout)
is established between the requesting VM and the unikernel. qrexec is
built on top of vchan, which was easy to support thanks to David
Scott's ocaml-vchan library.

A smal= l nitpick: although I've written a lot of vchan code recently, the orig= inal fully-working version was by Vincent Bernadoff (vbmithr on github)

Apart from that, awesome -- makes me want to buy a PC= laptop and install Qubes :-)

Cheers,
Da= ve
=C2=A0

I've also written a tool [2] to let you upload unikernels built in an AppVM to dom0 and run them easily.

For example:

$ mirage configure --xen
$ make
$ test-mirage mir-qubes-test.xen
Waiting for 'Ready'... OK
Uploading 'mir-qubes-test.xen' (4187256 bytes)
Waiting for 'Booting'... OK
--> Creating volatile image: /var/lib/qubes/appvms/mirage-test/volatile.= img...
--> Loading the VM (type =3D AppVM)...
--> Starting Qubes DB...
--> Setting Qubes DB info for the VM...
--> Updating firewall rules...
--> Starting the VM...
--> Starting the qrexec daemon...
Waiting for VM's qrexec agent.connected

Initialising console ... done.

A newbie question -- is there a decent PC ultrabook that anyone can recommend to start running Qubes with working power management? I've heard good things about Dell XPSes... Also, I just ran across this nicely privilege separated TLS daemon: https://www.opsmate.com/titus/ This seems like a good direction for TLStunnel to go in as well -- explicit fine-grained process/VM separation for even the private keys.

The deadline for this is tomorrow. I think a good one would be to submit the Unikernels+Docker integration from Barcelona. Although we didn't show it off in the short 10 minute Cool Hack slot, there's a really good story emerging around Mirage backed by Rumpkernel libraries.

After introducing unikernels, we will discuss the relationship between MirageOS (clean-slate) and Rumprun unikernels, and Linux Containers. We will then show how it is getting steadily easier to extend everyday workflows and deployments with unikernel technology. # Abstract (3-6 paragraphs, bullets welcome) Unikernels are a growing technology movement that augment existing virtual machine and container deployments with compact, single-purpose appliances. Two main flavours exist: clean-slate unikernels, often language-specific, such as MirageOS (OCaml, https://mirage.io) and HaLVM (Haskell); and more evolutionary unikernels that leverage existing OS technology recreated in library form, notably Rump Kernel (http://rumpkernel.org) used to build Rumprun unikernels. To date, these have been something of a specialist game: promising technology, but requiring considerable effort and expertise to actually deploy. After a brief introduction for newcomers to unikernels, we will demonstrate the great strides that have been taken recently to integrate unikernels with existing deployments. Specifically, we will show various ways in which Rumprun and MirageOS unikernels can be used to deploy a LAMP stack, all managed using the popular Docker toolchain (`docker build ...`, `docker run ...` and the Docker Hub). The result is that unikernels can be used to augment and evolve existing Linux container- and VM-based deployments one microservice at a time. We no longer need a revolution -- Welcome to the Evolution! # Audience takeway Unikernels are leveraging the Docker toolchain and ecosystem to make them easier to deploy and integrate with existing workflows.

Hi Wassim,

It's definitely possible to get the image size of MirageOS builds down = from where they are right now.=C2=A0 As background, there are two ways to b= uild unikernel images:

- Native code compilation: this generates fast x86_64/ARM unikernels that l= ink against the OCaml 'libasmrun' runtime to run as native executab= les.=C2=A0 In this mode, touching a single module will link the whole thing= in, even if only one function is used.=C2=A0 Thus, as modules grow, the he= llo world library size also grows.

- Bytecode compilation: this generates portable bytecode that is interprete= d by the 'ocamlrun' or 'libcamlrun' runtime.=C2=A0 There ex= ists a utility called 'ocamlclean' that does dead-code elimination = that eliminates all unused functions: https://github.com/avsm/ocamlclean.=C2=A0 T= his is how we got our sub-300k unikernels for DNS.

Now, we need to do a little work to get these back.=C2=A0 Either a native c= ode ocamlclean, or add a bytecode backend to the latest MirageOS (which is = native code only).=C2=A0 I suspect the easiest path is to build the bytecod= e backend in again, and then get ocamlclean working with the latest OCaml (= shouldnt be hard), and then investigate a native code ocamlclean as a Pione= er Project.

Hi Wassim,

It's definitely possible to get the image size of MirageOS builds down = from where they are right now.=C2=A0 As background, there are two ways to b= uild unikernel images:

- Native code compilation: this generates fast x86_64/ARM unikernels that l= ink against the OCaml 'libasmrun' runtime to run as native executab= les.=C2=A0 In this mode, touching a single module will link the whole thing= in, even if only one function is used.=C2=A0 Thus, as modules grow, the he= llo world library size also grows.

- Bytecode compilation: this generates portable bytecode that is interprete= d by the 'ocamlrun' or 'libcamlrun' runtime.=C2=A0 There ex= ists a utility called 'ocamlclean' that does dead-code elimination = that eliminates all unused functions: https://github.com/avsm/ocamlclean.=C2=A0 T= his is how we got our sub-300k unikernels for DNS.

Now, we need to do a little work to get these back.=C2=A0 Either a native c= ode ocamlclean, or add a bytecode backend to the latest MirageOS (which is = native code only).=C2=A0 I suspect the easiest path is to build the bytecod= e backend in again, and then get ocamlclean working with the latest OCaml (= shouldnt be hard), and then investigate a native code ocamlclean as a Pione= er Project.

Hi Mindy. Are you looking for a library that is compatible= with MirageOS? If so, what are those requirements, e.g. must it use Lwt or= be functorized against specific signatures? Is a dependency on Core_kernel= okay? Do you also want any compatibility with js_of_ocaml, e.g. there are = 2 ways to sign requests, one of which can be used on the client side.

Def not SOAP-based. = Uses the JSON descriptions provided by botocore[0], along with static type = overrides from amazonka[1] to generate code that uses the query API.
The error parsing's a little busted right now (produces un= helpful messages), which is the last thing that needs to be fixed before it= can be released. I'll try and dedicate some time to it this week. Mind= y, if you want to get a head start I can give you access the the repo befor= e the release.

Hi Mindy. Are you looking for a library that is compatible= with MirageOS? If so, what are those requirements, e.g. must it use Lwt or= be functorized against specific signatures? Is a dependency on Core_kernel= okay? Do you also want any compatibility with js_of_ocaml, e.g. there are = 2 ways to sign requests, one of which can be used on the client side.

Def not SOAP-based. = Uses the JSON descriptions provided by botocore[0], along with static type = overrides from amazonka[1] to generate code that uses the query API.
The error parsing's a little busted right now (produces un= helpful messages), which is the last thing that needs to be fixed before it= can be released. I'll try and dedicate some time to it this week. Mind= y, if you want to get a head start I can give you access the the repo befor= e the release.

Here's hoping that Spiros' version isn't a SOAP-based ge= nerator... :-)

However I haven't opened an issue, because I wasn't sure if there is a problem with my installation. My brute force approach to fix the issue was deleting $HOME/.opam/4.02.3/lib/userconf first and then after the next error I've also deleted $HOME/.opam/4.02.3/lib/plugin-loader.

However I haven't opened an issue, because I wasn't sure if there is a problem with my installation. My brute force approach to fix the issue was deleting $HOME/.opam/4.02.3/lib/userconf first and then after the next error I've also deleted $HOME/.opam/4.02.3/lib/plugin-loader. Then I was able to install the new version of oasis.

The OpenPGP message format is documented in RFC4880, including a custom run-length encoding of numbers, and various versions etc. I'm not sure (and couldn't easily find) whether it makes sense to support old versions (I think signature versions 3 and 4 are sensible, but maybe 3 could be dropped as well).

The OpenPGP message format is documented in RFC4880, including a custom run-length encoding of numbers, and various versions etc. I'm not sure (and couldn't easily find) whether it makes sense to support old versions (I think signature versions 3 and 4 are sensible, but maybe 3 could be dropped as well).

I was imagining the gpg-agent would run in a Qubes Mirage AppVM, which would also store the private keys (in a FAT filesystem maybe). When other (Linux) AppVMs want something signed or decrypted, they run the regular gpg binary, which calls a gpg-agent stub that uses `qvm-run mirage-gpg` to get a vchan to the Mirage agent. That way, private keys never leave the Mirage VM. Prompting the user for the password might be a problem, but we could call out to another AppVM for that (or maybe even to dom0). -- 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 Thu Nov 26 20:38:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 26 Nov 2015 20:38:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1a23JC-0003bW-RM; Thu, 26 Nov 2015 20:38:26 +0000 Received: from mail6.bemta14.messagelabs.com ([193.109.254.103]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1a23JB-0003av-8Q for mirageos-devel@lists.xenproject.org; Thu, 26 Nov 2015 20:38:25 +0000 Received: from [193.109.254.147] by server-15.bemta-14.messagelabs.com id 4B/1A-10115-0CD67565; Thu, 26 Nov 2015 20:38:24 +0000 X-Env-Sender: talex5@gmail.com X-Msg-Ref: server-4.tower-27.messagelabs.com!1448570302!6647984!1 X-Originating-IP: [209.85.213.41] X-SpamReason: No, hits=0.3 required=7.0 tests=RCVD_BY_IP X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 8558 invoked from network); 26 Nov 2015 20:38:23 -0000 Received: from mail-vk0-f41.google.com (HELO mail-vk0-f41.google.com) (209.85.213.41) by server-4.tower-27.messagelabs.com with AES128-GCM-SHA256 encrypted SMTP; 26 Nov 2015 20:38:23 -0000 Received: by vkay187 with SMTP id y187so58610309vka.3 for ; Thu, 26 Nov 2015 12:38:22 -0800 (PST) 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=51jvDvJK3tqUsahmvz0bSZYbVy1NkG6bhqa6YLms0ww=; b=JMY6pK1IpiDu1kJ/CXWF450VuOlxw71CBANcu9Aik3WtyyuvR9aBRe/lK7aRnJ5VpS vCbmsp+H+kODAac7jHBXQ2A7piNs3D2GImDsCE/diBhCVt9HwUSByOPblCX57u9xJBjN DkDoJDaJbUt6HZJE9bBBWc2fSgyeDn7+7n898UnF7/CKgkIGWsKZE3jHHkSq/2edR+XP eLQ9u2R/h5gzBWk0XTAYkDpJ6RCe7brcFEsu9V/1d0W1QanhJR6xYgg+sqp/n8rK1lTy L09Y5oRpPrRI53bW4fRzXxdKV2RwLY0H+PY8dcjslhyO5ZnL2BXUzW6nsxEOcvnLKpSK E1Ow== MIME-Version: 1.0 X-Received: by 10.31.54.136 with SMTP id d130mr40258775vka.124.1448570302320; Thu, 26 Nov 2015 12:38:22 -0800 (PST) Received: by 10.31.132.196 with HTTP; Thu, 26 Nov 2015 12:38:22 -0800 (PST) In-Reply-To: <56576AED.3040908@mehnert.org> References: <565729F4.8050701@mehnert.org> <56576AED.3040908@mehnert.org> Date: Thu, 26 Nov 2015 20:38:22 +0000 Message-ID: From: Thomas Leonard To: Hannes Mehnert Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] MirageOS AppVMs on Qubes 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 26 November 2015 at 20:26, Hannes Mehnert wrote: > On 11/26/2015 20:38, Thomas Leonard wrote: >> What about doing only the agent protocol (mainly PKDECRYPT and PKSIGN)? > > What would the benefit be?

Prompting the user for the password might be a problem, but we could call out to another AppVM for that (or maybe even to dom0). -- 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 Thu Nov 26 22:54:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 26 Nov 2015 22:54:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1a25Qi-00085J-KP; Thu, 26 Nov 2015 22:54:20 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1a25Qh-00085E-0E for mirageos-devel@lists.xenproject.org; Thu, 26 Nov 2015 22:54:19 +0000 Received: from [85.158.139.211] by server-14.bemta-5.messagelabs.com id 66/78-22142-A9D87565; Thu, 26 Nov 2015 22:54:18 +0000 X-Env-Sender: hannes@mehnert.org X-Msg-Ref: server-5.tower-206.messagelabs.com!1448578457!6815058!1 X-Originating-IP: [213.73.89.200] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 7.19.2; banners=-,-,- X-VirusChecked: Checked Received: (qmail 47684 invoked from network); 26 Nov 2015 22:54:17 -0000 Received: from mail.mehnert.org (HELO mail.mehnert.org) (213.73.89.200) by server-5.tower-206.messagelabs.com with DHE-RSA-CAMELLIA256-SHA encrypted SMTP; 26 Nov 2015 22:54:17 -0000 Received: from [192.168.0.11] (cpc30-cmbg15-2-0-cust247.5-4.cable.virginm.net [86.4.51.248]) (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 167181F32 for ; Thu, 26 Nov 2015 23:54:16 +0100 (CET) To: "mirageos-devel@lists.xenproject.org" References: <565729F4.8050701@mehnert.org> <56576AED.3040908@mehnert.org> From: Hannes Mehnert Openpgp: id=11B5464249B5BD858FFF6328BC896588DF7C28EE Message-ID: <56578D79.9010701@mehnert.org> Date: Thu, 26 Nov 2015 23:53:45 +0100 User-Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:38.0) Gecko/20100101 Thunderbird/38.3.0 MIME-Version: 1.0 In-Reply-To: Subject: Re: [MirageOS-devel] MirageOS AppVMs on Qubes 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: multipart/mixed; boundary="===============6848474718430302107==" Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --===============6848474718430302107== Content-Type: multipart/signed; micalg=pgp-sha384; protocol="application/pgp-signature"; boundary="JucnmnlxLaIX4guORv6aQlJTUVoNMWwPM" This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --JucnmnlxLaIX4guORv6aQlJTUVoNMWwPM Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable On 11/26/2015 21:38, Thomas Leonard wrote: > On 26 November 2015 at 20:26, Hannes Mehnert wrote= : >> On 11/26/2015 20:38, Thomas Leonard wrote: >>> What about doing only the agent protocol (mainly PKDECRYPT and PKSIGN= )? >> >> What would the benefit be?
