It's a shame every distribution package manager needs to duplicate the language-specific packaging. opam already puts each program in its own folder (mostly), allows switching and doesn't grant root privileges to installed software.

It's a shame every distribution package manager needs to duplicate the language-specific packaging. opam already puts each program in its own folder (mostly), allows switching and doesn't grant root privileges to installed software.

Good day,
 
To get straight to the point, I've been interested in Mirage over the last couple of weeks, and would like to continue using it over the coming years. My target platform is the cubietruck (CT); however, I've been running into a number of problems in trying to get it up and running.
 
Currently, the main issue I'm facing is that 'opam install mirage' doesn't proceed beyond the following point: "Processing  4/17: [ocamlfind: make all]". I've actually left it overnight, twice, using cleanly built images sourced from two completely seperate computers for each respective run, but it always gets stuck here.
 
This could be caused by the time not being set correctly. Does it work if you run "sudo ntpdate pool.ntp.org" ?

Currently, the main issue I'm facing is that 'opam install mirage' doesn't proceed beyond the following point: "Processing  4/17: [ocamlfind: make all]".

Ok,=C2=A0

I modified mirage-net-unix to= output a reasonable error message and apparently tun0 is being considered = "disconnected" during a read operation.
I have the test= s for it at least printing out just one "got packet of len [length]&qu= ot; now and then the interface gets "disconnected". This is the c= ode that detects the disconnection:

Lwt_cstruct.read t.dev buf >>=3D function |(-1) -> (* = EAGAIN or EWOULDBLOCK *) read t page |0 -> (* EOF *) return (`Error `Disconnected)

Is 0 really an EOF? Should it be considere= d a disconnect?

Anyway, I got the tests for mirage= -net-unix=C2=A0fully=C2=A0working with Ubuntu 12.04.5, and I assume I'l= l be able to get Mirage OS proper working now.

Should I submit a pull request for the modifications I made to mirage-net= -unix?

Thanks for all your help!

However, I don't have any "terminating" problem with tap0, so= I think
that problem is most likely unrelated to the persistence.

Ok,=C2=A0

I modified mirage-net-unix to= output a reasonable error message and apparently tun0 is being considered = "disconnected" during a read operation.
I have the test= s for it at least printing out just one "got packet of len [length]&qu= ot; now and then the interface gets "disconnected". This is the c= ode that detects the disconnection:

Lwt_cstruct.read t.dev buf >>=3D function |(-1) -> (* = EAGAIN or EWOULDBLOCK *) read t page |0 -> (* EOF *) return (`Error `Disconnected)

Is 0 really an EOF? Should it be considere= d a disconnect?

Anyway, I got the tests for mirage= -net-unix=C2=A0fully=C2=A0working with Ubuntu 12.04.5, and I assume I'l= l be able to get Mirage OS proper working now.

Should I submit a pull request for the modifications I made to mirage-net= -unix?

Thanks for all your help!

Actually, I just tried it and I have the same pr= oblem with tap0 not
being persistent on Ubuntu 14.04, and this is because
https:= //github.com/mirage/ocaml-tuntap hasn't been released yet since
PR #9.

However, I don't have any "terminating" problem with tap0, so= I think
that problem is most likely unrelated to the persistence.

However, I don't have any "terminating" problem with tap0, so I think

Actually, I just = tried it and I have the same problem with tap0 not
being persistent on Ubuntu 14.04, and this is because

PR #9.

However, I don't have any "terminating" problem with tap0, so I think
that problem is most likely unrelated to the persistence.

Hi,

I've been having a lot of fun with = bisect[1] recently-- I've been using it to see which parts of the = mirage-block-volume[2] and shared-block-ring[3] libraries are completely = untouched by their unit tests. I found the following game to be quite = addictive:

1. = "make coverage", and load result in web-browser
2. = spot a big chunk of obvious red (danger, danger, danger)
3. (thinking carefully about what could go wrong) devise an = interesting test to stress the red bits (obviously you could cover it = with a 'noddy' test but there is probably no point)
4. "make coverage", reload in browser and see the red go = green!

I've = hooked it up with coveralls.io (admittedly in a bit of a hacky way[4]) such = that the master branch is firmly in "development" mode, linking against = bisect, and without checking in the oasis autogen rubbish. The = .travis.yml runs both the travisci-skeleton script and then invokes = ocveralls[5] to upload the results.

I've added a separate "make release" = step which removes bisect and checks in the autogen (presumably into a = release branch). Perhaps eventually this could make a github pull = request (with the "hub" tool?) and make an opam package?

I think the game is made = even more addictive when the coveralls badge changes colour, = see:

https://coveralls.io/r/mirage/mirage-block-volume?branch=3Dmast= er

Here's an example bisect report (the code is a = work-in-progress):

If = you haven't given bisect a go -- I recommend playing with it.

Also, if you can think = of a nicer way to integrate this -- I admit using 'sed' on the _oasis = file is a bit of a hack -- please let me know!

Along with the mentioned Puppet module I'm writing a set of acceptance tests. These can be set to run periodically, or just be run manually. They will spin up a virtual machine, run the Puppet code (to install mirage), build a unix unikernel, build a xen unikernel, run the unix unikernel and assert that all of that worked (ie. no errors) and that the unikernel works (probably a simple http server).

Bisect is GPL. Is it compatible with Mirage's license?= BTW, what is Mirage's license? I don't see it in the main repo.

Hi,

I've been ha= ving a lot of fun with bisect[1] recently-- I've been using it to see w= hich parts of the mirage-block-volume[2] and shared-block-ring[3] libraries= are completely untouched by their unit tests. I found the following game t= o be quite addictive:

1. "make coverage"= , and load result in web-browser
2. spot a big chunk of obvious r= ed (danger, danger, danger)
3. (thinking carefully about what cou= ld go wrong) devise an interesting test to stress the red bits (obviously y= ou could cover it with a 'noddy' test but there is probably no poin= t)
4. "make coverage", reload in browser and see the re= d go green!

I've hooked it up with coveralls.io (admittedly in a bi= t of a hacky way[4]) such that the master branch is firmly in "develop= ment" mode, linking against bisect, and without checking in the oasis = autogen rubbish. The .travis.yml runs both the travisci-skeleton script and= then invokes ocveralls[5] to upload the results.

= I've added a separate "make release" step which removes bisec= t and checks in the autogen (presumably into a release branch). Perhaps eve= ntually this could make a github pull request (with the "hub" too= l?) and make an opam package?

I think the game is = made even more addictive when the coveralls badge changes colour, see:


Here'= s an example bisect report (the code is a work-in-progress):

If you haven't given bisect a go -- I recommend pla= ying with it.

Also, if you can think of a nicer wa= y to integrate this -- I admit using 'sed' on the _oasis file is a = bit of a hack -- please let me know!

Cheers,

Bisect is GPL. Is it compatible with Mirage's license?= BTW, what is Mirage's license? I don't see it in the main repo.

Hi,

I've been ha= ving a lot of fun with bisect[1] recently-- I've been using it to see w= hich parts of the mirage-block-volume[2] and shared-block-ring[3] libraries= are completely untouched by their unit tests. I found the following game t= o be quite addictive:

1. "make coverage"= , and load result in web-browser
2. spot a big chunk of obvious r= ed (danger, danger, danger)
3. (thinking carefully about what cou= ld go wrong) devise an interesting test to stress the red bits (obviously y= ou could cover it with a 'noddy' test but there is probably no poin= t)
4. "make coverage", reload in browser and see the re= d go green!

I've hooked it up with coveralls.io (admittedly in a bi= t of a hacky way[4]) such that the master branch is firmly in "develop= ment" mode, linking against bisect, and without checking in the oasis = autogen rubbish. The .travis.yml runs both the travisci-skeleton script and= then invokes ocveralls[5] to upload the results.

= I've added a separate "make release" step which removes bisec= t and checks in the autogen (presumably into a release branch). Perhaps eve= ntually this could make a github pull request (with the "hub" too= l?) and make an opam package?

I think the game is = made even more addictive when the coveralls badge changes colour, see:


Here'= s an example bisect report (the code is a work-in-progress):

If you haven't given bisect a go -- I recommend pla= ying with it.

Also, if you can think of a nicer wa= y to integrate this -- I admit using 'sed' on the _oasis file is a = bit of a hack -- please let me know!

Cheers,

Examples include Redis or PostgreSQL for this (and probably many more

There's an interesting ongoing effort to port existing databases into a unikernel by Martin Lucina, so we should be able to run them in a
separate address space shortly.=C2=A0 For now though, a database in a Linux=
VM with the frontend as a unikernel client makes most sense.=C2=A0 What
sort of database access patterns do you anticipate?

There's an interesting ongoing effort to port existing databases into a unikernel by Martin Lucina, so we should be able to run them in a
separate address space shortly.=C2=A0 For now though, a database in a Linux=

That's one of the things I'd like to fix, or at least make i= t easy to
see whether it's working.

Along with the mentioned Puppet module I'm writing a set of acceptance<= br> tests. These can be set to run periodically, or just be run manually.
They will spin up a virtual machine, run the Puppet code (to install
mirage), build a unix unikernel, build a xen unikernel, run the unix
unikernel and assert that all of that worked (ie. no errors) and that
the unikernel works (probably a simple http server). If you wanted to
run a shell script instead of run Puppet you should be able to drop
that in easily enough.

I have this partially working with Trusty now. Once I've got that
actually working I'll ship it and probably work on verifying Vivid
support.

That's one of the things I'd like to fix, or at least make i= t easy to
see whether it's working.

Along with the mentioned Puppet module I'm writing a set of acceptance<= br> tests. These can be set to run periodically, or just be run manually.
They will spin up a virtual machine, run the Puppet code (to install
mirage), build a unix unikernel, build a xen unikernel, run the unix
unikernel and assert that all of that worked (ie. no errors) and that
the unikernel works (probably a simple http server). If you wanted to
run a shell script instead of run Puppet you should be able to drop
that in easily enough.

I have this partially working with Trusty now. Once I've got that
actually working I'll ship it and probably work on verifying Vivid
support.

I have sent a pull request to fix the requires root issue - it was trying to bring the interface up which requires root, so long as it is already up this is fine, I use: sudo ip tuntap add dev tap0 mode tap user justin && sudo ip link set dev tap0 up to create interfaces. The disappearing thing is the interface going down again, it is not a persistence thing, as it is not actually removed.

I have sent a pull request to fix the requires root issue - it was trying to bring the interface up which requires root, so long as it is already up this is fine, I use: sudo ip tuntap add dev tap0 mode tap user justin && sudo ip link set dev tap0 up to create interfaces. The disappearing thing is the interface going down again, it is not a persistence thing, as it is not actually removed. In addition it seems that some types of Linux tap devices return 0 when there is nothing to read, rather than EAGAIN as you would expect, will send another pull request to work around this...

Is there a standard Puppet module used for the virtual machine spinup (i.e. does it use libxl, or xm, or something else for Xen?).

I've = hooked it up with coveralls.io (admittedly in a bit of a hacky way[4]) such = that the master branch is firmly in "development" mode, linking against = bisect, and without checking in the oasis autogen rubbish.

I've added a separate "make release" = step which removes bisect and checks in the autogen (presumably into a = release branch). Perhaps eventually this could make a github pull = request (with the "hub" tool?) and make an opam package?

I think the game is made = even more addictive when the coveralls badge changes colour, = see:

Here's an example bisect report (the code is a = work-in-progress):

If = you haven't given bisect a go -- I recommend playing with it.

Also, if you can think = of a nicer way to integrate this -- I admit using 'sed' on the _oasis = file is a bit of a hack -- please let me know!

I've = hooked it up with coveralls.io (admittedly in a bit of a hacky way[4]) such = that the master branch is firmly in "development" mode, linking against = bisect, and without checking in the oasis autogen rubbish. The = .travis.yml runs both the travisci-skeleton script and then invokes = ocveralls[5] to upload the results.

I've added a separate "make release" = step which removes bisect and checks in the autogen (presumably into a = release branch). Perhaps eventually this could make a github pull = request (with the "hub" tool?) and make an opam package?

I think the game is made = even more addictive when the coveralls badge changes colour, = see:

https://coveralls.io/r/mirage/mirage-block-volume?branch=3Dmast= er

Here's an example bisect report (the code is a = work-in-progress):

http://dave.recoil.org/tmp/report/file0000.html

If = you haven't given bisect a go -- I recommend playing with it.

Also, if you can think = of a nicer way to integrate this -- I admit using 'sed' on the _oasis = file is a bit of a hack -- please let me know!

Cheers,
Dave

Odd, I can't replicate that, in fact I can't create any interfaces which don't have multicast and broadcast set. On the other hand, IFF_UP is the only flag that actually matters at this point, so just testing for that would be sufficient.

I tried that, and what I usually use as it is always installed by default: sudo ip tuntap add dev tap0 mode tap user justin && sudo ip link set dev tap0 up Both but broadcast and multicast flags on - indeed, looking at my network interfaces they all have those flags on except loopback (eg just use ifconfig or ip link to show).

I'm releasing tcpip 2.4.3 with the fix and it will be in opam shortly: https://github.com/ocaml/opam-repository/pull/4051 As usual, any contribution in term of new tests is always very welcome: https://github.com/mirage/mirage-tcpip/tree/master/lib_test Best, Thomas > On 30 Apr 2015, at 12:29, Anil Madhavapeddy wrote: > > Thanks Mindy and Thomas!

I'm not sure it was ever announced on this list, so here's the link for people interested in the ARP-cache-on-Irmin experiments (I assume this is what you're referring to): http://www.somerandomidiot.com/blog/2015/04/24/what-a-distributed-version-controlled-ARP-cache-gets-you/ We do need more Irmin tutorials though.

I'm starting a new thread to avoid potentially hijacking a more general conversation on testing with this rather more specific proposal, but most of what I'm discussing is quite related to problems and solutions enumerated in "Notes on Testing" from a few hours ago, and some item are reflected in ARs there. I thought I'd take a run at writing down what I've gotten out of corridor and backchannel conversations with many other Mirage-seekers around restructuring the lump of code we currently keep in the `tcpip` repository (probably the most-used set of `impl`s in Mirage). TL;DR - We should have each protocol in `tcpip` expose serializing and deserializing APIs for external use, in addition to including its own test suite and having clearer documentation of expectations around data ingress and egress (as included in Mort's notes). I further propose that it may be useful to split each protocol into its own package for use in situations other than "a full ethernet/ip/tcp/udp/dhcp stack assembled by the mirage frontend tool". We should also 1) figure out which of the error exposing/handling proposals won and 2) start using whichever one it is. The long version: What I've read, heard, and thought some reasonable goals are: * make it easier to test the code we have that does stuff with packets (and if we do a good job, we might find a more generally useful model) * write and automatically perform some tests on our packet-handling code * make it clearer when errors occur at low levels so higher-level applications can deal with them appropriately * make API contracts between layers clearer (what blocks?) * make it easier to reuse code across projects when that code needs to know stuff about packets Code reuse might be a surprising thing to see here mixed in with quality and testing. Here's some stuff that's in at least two places I know of for "a network stack", i.e. /ethernet/arp-and-ipv4,6/icmp/udp/tcp: * wire format definitions (i.e. Cstructs) - Wire_structs (from `tcpip`), the module for serializing and deserializing wire formats of static size via the autogenerated Cstruct interface, doesn't seem to be explicitly intended to be exposed in `tcpip`. - ocaml-packet (all in `Packet.ml`) - ocaml-pcap (each format in its own .ml) * serializing/deserializing code - all over `tcpip`, usually inaccessible or side-effecting (notable exception: dhcp) - ocaml-packet . notably ocaml-packet currently depends on `tcpip` for `tcpip_checksum.ml` and required externs - ocaml-pcap 0.4.0 also has serializing and deserializing code per protocol, bundled with wire formats. ocaml-pcap doesn't currently duplicate many application-layer protocols, although a more featureful `ocaml-pcap` will likely want to either do that or make common reference to parsing code. - mirage-nat and mirage-mimic, because I needed more than Wire_structs but less than a full listener Here's what *isn't* all over the place: * state machines/side-effecting operations/protocol implementations - `tcpip` is the only library I know of that implements anything beyond a parser/printer for a protocol below the application layer, although I'm certainly one of the less knowledgeable people about non-Mirage OCaml codebases on the list * automated test code for any of the aforementioned * ocaml-packet checks that deserializing a type and then serializing the result gets you the original type * `tcpip`: now with tests (TM) ...but it could use some more ;) * application-layer code is doing a better job, but that doesn't get it much if the code beneath is unreliable Things that might help with both reuse and accessibility for testing: * pull Wire_structs into a separate library and make its wider usability clear and stable, where appropriate - currently some things are treated as constant-size cstructs that shouldn't be, e.g. ipv4 packets which might have options and therefore be larger than Wire_structs expects; exposing these widely without richer options for serializing and deserializing might be counterproductive.

Mort's writeup of notes from a conversation on testing raises some questions on how to actually go about testing `tcpip`.=C2=A0 I'm star= ting a new thread to avoid potentially hijacking a more general conversation on testing with this rather more specific proposal, but most of what I'm discussing is quite related to problems and solutions enumerated in "Notes on Testing" from a few hours ago, and some item are reflected in ARs there.=C2=A0 I thought I'd take a run = at writing down what I've gotten out of corridor and backchannel conversations with many other Mirage-seekers around restructuring the lump of code we currently keep in the `tcpip` repository (probably the most-used set of `impl`s in Mirage).

TL;DR - We should have each protocol in `tcpip` expose serializing and deserializing APIs for external use, in addition to including its own test suite and having clearer documentation of expectations around data ingress and egress (as included in Mort's notes).=C2=A0 I further propose that it may be useful to split each protocol into its own package for use in situations other than "a full ethernet/ip/tcp/udp/dhcp stack assembled by the mirage frontend tool".

We should also 1) figure out which of the error exposing/handling proposals won and 2) start using whichever one it is.

The long version:

What I've read, heard, and thought some reasonable goals are:
=C2=A0 * make it easier to test the code we have that does stuff with packets (and if we do a good job, we might find a more generally useful model)
=C2=A0 * write and automatically perform some tests on our packet-handling code
=C2=A0 * make it clearer when errors occur at low levels so higher-le= vel applications can deal with them appropriately
=C2=A0 * make API contracts between layers clearer (what blocks?)
=C2=A0 * make it easier to reuse code across projects when that code needs to know stuff about packets

Code reuse might be a surprising thing to see here mixed in with quality and testing.=C2=A0 Here's some stuff that's in at least two places I know of for "a network stack", i.e. /ethernet/arp-and-ipv4,6/icmp/udp/tcp:

* wire format definitions (i.e. Cstructs)
=C2=A0 - Wire_structs (from `tcpip`), the module for serializing and deserializing wire formats of static size via the autogenerated Cstruct interface, doesn't seem to be explicitly intended to be exposed in `tcpip`.
=C2=A0 - ocaml-packet (all in `Packet.ml`)
=C2=A0 - ocaml-pcap (each format in its own .ml)
* serializing/deserializing code
=C2=A0 - all over `tcpip`, usually inaccessible or side-effecting (notable exception: dhcp)
=C2=A0 - ocaml-packet .=C2=A0 notably ocaml-packet currently depends = on `tcpip` for `tcpip_checksum.ml` and required externs
=C2=A0 - ocaml-pcap 0.4.0 also has serializing and deserializing code= per protocol, bundled with wire formats.=C2=A0 ocaml-pcap doesn't current= ly duplicate many application-layer protocols, although a more featureful `ocaml-pcap` will likely want to either do that or make common reference to parsing code.
=C2=A0 - mirage-nat and mirage-mimic, because I needed more than Wire_structs but less than a full listener

Here's what *isn't* all over the place:
* state machines/side-effecting operations/protocol implementations
=C2=A0 - `tcpip` is the only library I know of that implements anythi= ng beyond a parser/printer for a protocol below the application layer, although I'm certainly one of the less knowledgeable people about non-Mirage OCaml codebases on the list
* automated test code for any of the aforementioned
=C2=A0 * ocaml-packet checks that deserializing a type and then serializing the result gets you the original type
=C2=A0 * `tcpip`: now with tests (TM) ...but it could use some more ;= )
=C2=A0 * application-layer code is doing a better job, but that doesn= 't get it much if the code beneath is unreliable

Things that might help with both reuse and accessibility for testing:
* pull Wire_structs into a separate library and make its wider usability clear and stable, where appropriate
=C2=A0 - currently some things are treated as constant-size cstructs = that shouldn't be, e.g. ipv4 packets which might have options and therefore be larger than Wire_structs expects; exposing these widely without richer options for serializing and deserializing might be counterproductive.=C2=A0 Libraries that duplicate Wire_structs seem t= o all share this problem, so a common solution would likely be useful.

* pull per-protocol serializing and deserializing code into its own modules
=C2=A0 - improve and formalize error communication for invalid data, = and express these in mirage-types module types
=C2=A0 - write tests for serializing and deserializing modules

* possibly pull the serializing/deserializing modules into their own package (packages?) on which `tcpip` depends (or maybe a separate library within `tcpip`?), for common use outside of `tcpip` itself

* attempt to improve and write tests on the code in `tcpip` that *isn't* digging around in or making packets, which should be logic for acting on write and read requests (at a low level)
=C2=A0 - improve and formalize (create?) error communication for bad state transitions, syntactically OK but semantically bogus packets, etc
=C2=A0 - possibly it makes sense to break this package up entirely in= to separate protocol implementations and rely on the `mirage` frontend tool (or user request, outside of the Mirage ecosystem) to manage dependencies between them - see below

Most of the above is focused on splitting up the code in `tcpip`; there are probably other ways to do it, and likely some of them make more sense than what I'm proposing.=C2=A0 It seems to me that there a= re (at least) two reasonable ways to split up some of the code in `tcpip`:
* horizontally layerwise, i.e. all code to do with ARP is in one package (serializing/deserializing, state machine/side effects), same for ipv4, ipv6, etc
* vertically concernwise, i.e. all serializing/deserializing code is in the same place, all action-taking code (probably with some more sensible subdivision) is in the same place, etc
* some other way I haven't thought of that makes way more sense (your proposal here!)

I'm starting a new thread to avoid potentially hijacking a more general conversation on testing with this rather more specific proposal, but most of what I'm discussing is quite related to problems and solutions enumerated in "Notes on Testing" from a few hours ago, and some item are reflected in ARs there. I thought I'd take a run at writing down what I've gotten out of corridor and backchannel conversations with many other Mirage-seekers around restructuring the lump of code we currently keep in the `tcpip` repository (probably the most-used set of `impl`s in Mirage). TL;DR - We should have each protocol in `tcpip` expose serializing and deserializing APIs for external use, in addition to including its own test suite and having clearer documentation of expectations around data ingress and egress (as included in Mort's notes). I further propose that it may be useful to split each protocol into its own package for use in situations other than "a full ethernet/ip/tcp/udp/dhcp stack assembled by the mirage frontend tool". We should also 1) figure out which of the error exposing/handling proposals won and 2) start using whichever one it is. The long version: What I've read, heard, and thought some reasonable goals are: * make it easier to test the code we have that does stuff with packets (and if we do a good job, we might find a more generally useful model) * write and automatically perform some tests on our packet-handling code * make it clearer when errors occur at low levels so higher-level applications can deal with them appropriately * make API contracts between layers clearer (what blocks?) * make it easier to reuse code across projects when that code needs to know stuff about packets Code reuse might be a surprising thing to see here mixed in with quality and testing. Here's some stuff that's in at least two places I know of for "a network stack", i.e. /ethernet/arp-and-ipv4,6/icmp/udp/tcp: * wire format definitions (i.e. Cstructs) - Wire_structs (from `tcpip`), the module for serializing and deserializing wire formats of static size via the autogenerated Cstruct interface, doesn't seem to be explicitly intended to be exposed in `tcpip`. - ocaml-packet (all in `Packet.ml`) - ocaml-pcap (each format in its own .ml) * serializing/deserializing code - all over `tcpip`, usually inaccessible or side-effecting (notable exception: dhcp) - ocaml-packet . notably ocaml-packet currently depends on `tcpip` for `tcpip_checksum.ml` and required externs - ocaml-pcap 0.4.0 also has serializing and deserializing code per protocol, bundled with wire formats. ocaml-pcap doesn't currently duplicate many application-layer protocols, although a more featureful `ocaml-pcap` will likely want to either do that or make common reference to parsing code. - mirage-nat and mirage-mimic, because I needed more than Wire_structs but less than a full listener Here's what *isn't* all over the place: * state machines/side-effecting operations/protocol implementations - `tcpip` is the only library I know of that implements anything beyond a parser/printer for a protocol below the application layer, although I'm certainly one of the less knowledgeable people about non-Mirage OCaml codebases on the list * automated test code for any of the aforementioned * ocaml-packet checks that deserializing a type and then serializing the result gets you the original type * `tcpip`: now with tests (TM) ...but it could use some more ;) * application-layer code is doing a better job, but that doesn't get it much if the code beneath is unreliable Things that might help with both reuse and accessibility for testing: * pull Wire_structs into a separate library and make its wider usability clear and stable, where appropriate - currently some things are treated as constant-size cstructs that shouldn't be, e.g. ipv4 packets which might have options and therefore be larger than Wire_structs expects; exposing these widely without richer options for serializing and deserializing might be counterproductive.

Mort's writeup of notes from a conversation on testing raises some questions on how to actually go about testing `tcpip`.=C2=A0 I'm star= ting a new thread to avoid potentially hijacking a more general conversation on testing with this rather more specific proposal, but most of what I'm discussing is quite related to problems and solutions enumerated in "Notes on Testing" from a few hours ago, and some item are reflected in ARs there.=C2=A0 I thought I'd take a run = at writing down what I've gotten out of corridor and backchannel conversations with many other Mirage-seekers around restructuring the lump of code we currently keep in the `tcpip` repository (probably the most-used set of `impl`s in Mirage).

TL;DR - We should have each protocol in `tcpip` expose serializing and deserializing APIs for external use, in addition to including its own test suite and having clearer documentation of expectations around data ingress and egress (as included in Mort's notes).=C2=A0 I further propose that it may be useful to split each protocol into its own package for use in situations other than "a full ethernet/ip/tcp/udp/dhcp stack assembled by the mirage frontend tool".

We should also 1) figure out which of the error exposing/handling proposals won and 2) start using whichever one it is.

The long version:

What I've read, heard, and thought some reasonable goals are:
=C2=A0 * make it easier to test the code we have that does stuff with packets (and if we do a good job, we might find a more generally useful model)
=C2=A0 * write and automatically perform some tests on our packet-handling code
=C2=A0 * make it clearer when errors occur at low levels so higher-le= vel applications can deal with them appropriately
=C2=A0 * make API contracts between layers clearer (what blocks?)
=C2=A0 * make it easier to reuse code across projects when that code needs to know stuff about packets

Code reuse might be a surprising thing to see here mixed in with quality and testing.=C2=A0 Here's some stuff that's in at least two places I know of for "a network stack", i.e. /ethernet/arp-and-ipv4,6/icmp/udp/tcp:

* wire format definitions (i.e. Cstructs)
=C2=A0 - Wire_structs (from `tcpip`), the module for serializing and deserializing wire formats of static size via the autogenerated Cstruct interface, doesn't seem to be explicitly intended to be exposed in `tcpip`.
=C2=A0 - ocaml-packet (all in `Packet.ml`)
=C2=A0 - ocaml-pcap (each format in its own .ml)
* serializing/deserializing code
=C2=A0 - all over `tcpip`, usually inaccessible or side-effecting (notable exception: dhcp)
=C2=A0 - ocaml-packet .=C2=A0 notably ocaml-packet currently depends = on `tcpip` for `tcpip_checksum.ml` and required externs
=C2=A0 - ocaml-pcap 0.4.0 also has serializing and deserializing code= per protocol, bundled with wire formats.=C2=A0 ocaml-pcap doesn't current= ly duplicate many application-layer protocols, although a more featureful `ocaml-pcap` will likely want to either do that or make common reference to parsing code.
=C2=A0 - mirage-nat and mirage-mimic, because I needed more than Wire_structs but less than a full listener

Here's what *isn't* all over the place:
* state machines/side-effecting operations/protocol implementations
=C2=A0 - `tcpip` is the only library I know of that implements anythi= ng beyond a parser/printer for a protocol below the application layer, although I'm certainly one of the less knowledgeable people about non-Mirage OCaml codebases on the list
* automated test code for any of the aforementioned
=C2=A0 * ocaml-packet checks that deserializing a type and then serializing the result gets you the original type
=C2=A0 * `tcpip`: now with tests (TM) ...but it could use some more ;= )
=C2=A0 * application-layer code is doing a better job, but that doesn= 't get it much if the code beneath is unreliable

Things that might help with both reuse and accessibility for testing:
* pull Wire_structs into a separate library and make its wider usability clear and stable, where appropriate
=C2=A0 - currently some things are treated as constant-size cstructs = that shouldn't be, e.g. ipv4 packets which might have options and therefore be larger than Wire_structs expects; exposing these widely without richer options for serializing and deserializing might be counterproductive.=C2=A0 Libraries that duplicate Wire_structs seem t= o all share this problem, so a common solution would likely be useful.

* pull per-protocol serializing and deserializing code into its own modules
=C2=A0 - improve and formalize error communication for invalid data, = and express these in mirage-types module types
=C2=A0 - write tests for serializing and deserializing modules

* possibly pull the serializing/deserializing modules into their own package (packages?) on which `tcpip` depends (or maybe a separate library within `tcpip`?), for common use outside of `tcpip` itself

* attempt to improve and write tests on the code in `tcpip` that *isn't* digging around in or making packets, which should be logic for acting on write and read requests (at a low level)
=C2=A0 - improve and formalize (create?) error communication for bad state transitions, syntactically OK but semantically bogus packets, etc
=C2=A0 - possibly it makes sense to break this package up entirely in= to separate protocol implementations and rely on the `mirage` frontend tool (or user request, outside of the Mirage ecosystem) to manage dependencies between them - see below

Most of the above is focused on splitting up the code in `tcpip`; there are probably other ways to do it, and likely some of them make more sense than what I'm proposing.=C2=A0 It seems to me that there a= re (at least) two reasonable ways to split up some of the code in `tcpip`:

* vertically concernwise, i.e. all serializing/deserializing code is in the same place, all action-taking code (probably with some more sensible subdivision) is in the same place, etc
* some other way I haven't thought of that makes way more sense (your proposal here!)

Thanks for your email Mindy!

We should also 1) figure out which of the error exposing/handling proposals won and 2) start using whichever one it is.

I had a first experimentation[1] with the new error handling based on Rresult[2]. The branch needs to be rebased and need more feedback, but I think that's the direction in which we should go.


An other point which is cruelly missing is a proper logging system - which is central when debugging runtime errors.

Most of the above is focused on splitting up the code in `tcpip`; there are probably other ways to do it, and likely some of them make more sense than what I'm proposing.  It seems to me that there are (at least) two reasonable ways to split up some of the code in `tcpip`:
* horizontally layerwise, i.e. all code to do with ARP is in one package (serializing/deserializing, state machine/side effects), same for ipv4, ipv6, etc
* vertically concernwise, i.e. all serializing/deserializing code is in the same place, all action-taking code (probably with some more sensible subdivision) is in the same place, etc
* some other way I haven't thought of that makes way more sense (your proposal here!)

A horizontal division is the only thing that really potentially gives any benefit for users that I can see - linking in only the layers we need makes for smaller binaries (at least until we have dead code elimination).  It also seems to have less potential for external API breakage causing other repositories to become unbuildable (thinking of the case where e.g. I want to support a new DHCP option, which might require me to both expose a new variant type for DHCP.Option.t and write some handling code in what's currently dhcpv4_client.ml); in a regime where the serializing/deserializing code and the actual implementations which receive and send data are in separate packages, they need separate, coordinated releases.  As a bonus, we already have module types in `mirage-types` for defining reasonable interfaces between these layers.

I think both splits make sense:

- you want an horizontal split for opam packages, as you want to be able to select which part of the network layer you want to assemble in your final application, and do not worry about installing the rest of the stack

- you want a vertical split in each packages (separate libraries for instance) to separate the IO code (serialization/deserialization) from the "pure" state-machine logic. The TLS code is a good example of that.

To go in that direction, I really would like to split the channel library from tcpip, so I'll probably do that today :-)

Best,
Thomas

charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org As mentioned a few days ago, I've just pushed an initial release of a Puppet module to install OCaml, OPAM and Mirage. https://github.com/garethr/garethr-mirageos https://forge.puppetlabs.com/garethr/mirageos This currently supports Ubuntu 12.04 and 14.04. If you have Puppet installed then getting setup with Mirage is as simple as 'include mirageos'. More details in the README for those interested. Some folks might just be interested in the testing approach, as it's applicable to any method of installation and could be extracted from the module. I've used Test Kitchen (http://kitchen.ci/) here, which supports multiple backends. I didn't find a Xen backend, but the current example uses the Vagrant backend, and I think you could use the Vagrant Xen provider to get there. The tests themselves use both ServerSpec (http://serverspec.org) and Bats (https://github.com/sstephenson/bats). The general approach is: * Test Kitchen spin up virtual machines (one per supported OS) * Install Puppet * Use the module to install OCaml, OPAM, Mirage, etc. * Run some tests verifying packages have been installed and mirage and opam are working (https://github.com/garethr/garethr-mirageos/blob/master/test/integration/default/serverspec/mirageos_spec.rb) * Run some tests that configure and build a unix unikernel, run the resulting binary and test that it works (https://github.com/garethr/garethr-mirageos/blob/master/test/integration/default/bats/mirageos.bats) (Only the install and run puppet steps are specific to Puppet. You could use the same config to run a shell provisioner and test a shell script if you wanted.) I don't have Travis running the tests at the moment, but the easiest way of doing that would be to use a different Test Kitchen backend spinning up remote machines (I tend to use Digital Ocean as it's very cost effective for short jobs).

If you have Puppet installed then getting setup with Mirage is as simple as 'include mirageos'. More details in the README for those interested. Some folks might just be interested in the testing approach, as it's applicable to any method of installation and could be extracted from the module. I've used Test Kitchen (http://kitchen.ci/) here, which supports multiple backends. I didn't find a Xen backend, but the current example uses the Vagrant backend, and I think you could use the Vagrant Xen provider to get there. The tests themselves use both ServerSpec (http://serverspec.org) and Bats (https://github.com/sstephenson/bats). The general approach is: * Test Kitchen spin up virtual machines (one per supported OS) * Install Puppet * Use the module to install OCaml, OPAM, Mirage, etc. * Run some tests verifying packages have been installed and mirage and opam are working (https://github.com/garethr/garethr-mirageos/blob/master/test/integration/default/serverspec/mirageos_spec.rb) * Run some tests that configure and build a unix unikernel, run the resulting binary and test that it works (https://github.com/garethr/garethr-mirageos/blob/master/test/integration/default/bats/mirageos.bats) (Only the install and run puppet steps are specific to Puppet. You could use the same config to run a shell provisioner and test a shell script if you wanted.) I don't have Travis running the tests at the moment, but the easiest way of doing that would be to use a different Test Kitchen backend spinning up remote machines (I tend to use Digital Ocean as it's very cost effective for short jobs). I'll try and write a blog post about it when I get a moment but if anyone has an questions, or wants a hand getting it up and running, let me know.

Hi,

How can mirage trace viewer be used on Citrix xenserver? I was trying to run the binary version (x86_64) on xenserver 6.5.0 but it requires glibc 2.7, while the latest version on xenserver is 2.5. Compiling from source on xenserver would be a pain.

Any instructions?

Thanks.

Now that the TLS stack is spooled up for integration (and running live on https://mirage.io!), this is actually top of my list. There are a few properties I want from a logging library: - An extremely small core interface, with just the "log" function (and associated format string ones). This lets us have a trivial, dependency free implementation that just logs to stdout or the Xen console. - Ability to branch logging contexts, to have hierarchical logs. This lets us map to both Irmin and the JavaScript logging interface very effectively. See [1] for the Firebug console.group() function. - Build more complex backends over this basis. For instance, the conventional "info/error/debug" one would be a layer that does the branches appropriately for each type. Another guideline is Thomas Leonard's profiling library, which should hook into this logging layer. Finally, the Xen backend should use Irmin to provide a Git logging backend, where log branches are actual Git branches. - Ban all uses of console logging from all of our protocol libraries. We should *never* be logging directly to the console, as this is both a denial-of-service opportunity and something that is very difficult to aggregate and track. My thinking is that by keeping the core interface down to one function, it should be possible for the application to be passed a logging function very easily (~log), and for the build system to assemble the appropriate logging backend for the environment at hand. We could then add a ~log function to Cohttp, DNS, TCPIP etc, with a PPX/Camlp4 extension to make it a lazy function for when we don't want it to be evaluated all the time. What I don't want is something like Dolog, which is a fine logging library, but a bit too specific to be used pervasively throughout our protocol libraries that must remain portable and lightweight across multiple compilation environments. Thoughts on this most welcome... I feel that building this library is quite simple, but getting the design right is critical as it will be a dependency on every library that we have.

Expensive logging can just be hidden behind an explicit if/else, since we really do want logging to be turned on by default in production deployments (and so it should be cheap enough by default, and factored into performance benchmarks). -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 May 12 16:06:01 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 12 May 2015 16:06:01 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YsCgz-0006Ke-9X; Tue, 12 May 2015 16:06:01 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YsCgx-0006KL-Vh for mirageos-devel@lists.xenproject.org; Tue, 12 May 2015 16:06:00 +0000 Received: from [85.158.139.211] by server-16.bemta-5.messagelabs.com id 58/B6-02824-7E422555; Tue, 12 May 2015 16:05:59 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-5.tower-206.messagelabs.com!1431446758!14408222!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.2 required=7.0 tests=RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.14; banners=-,-,- X-VirusChecked: Checked Received: (qmail 12294 invoked from network); 12 May 2015 16:05:58 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-5.tower-206.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 12 May 2015 16:05:58 -0000 Received: from [10.0.0.96] (host81-149-102-120.in-addr.btopenworld.com [81.149.102.120]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id 6f4a0470; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Tue, 12 May 2015 17:05:58 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: <555220B9.8000302@zoho.com> Date: Tue, 12 May 2015 17:05:58 +0100 Message-Id: <9CC63A6E-41B8-4BF2-BFCA-9D49AEE987C4@recoil.org> References: <5549E190.7080505@somerandomidiot.com> <7A8FE72F-2BDC-4E72-A6DE-CA56379F7C20@recoil.org> <4382CFB50FD64AFDA863FB6244D3FEA5@erratique.ch> <32C35BEB-47BF-4BC6-ACBB-844A7D778BD4@recoil.org> <555220B9.8000302@zoho.com> To: Drup X-Mailer: Apple Mail (2.2098) Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] Logging 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 12 May 2015, at 16:48, Drup wrote: > >> Agreed.

Expensive logging can just be hidden behind an explicit if/else, since we really do want logging to be turned on by default in production deployments (and so it should be cheap enough by default, and factored into performance benchmarks). -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 May 12 16:08:00 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 12 May 2015 16:08:00 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YsCiu-0006iy-Cc; Tue, 12 May 2015 16:08:00 +0000 Received: from mail6.bemta5.messagelabs.com ([195.245.231.135]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YsCit-0006iY-Ao for mirageos-devel@lists.xenproject.org; Tue, 12 May 2015 16:07:59 +0000 Received: from [85.158.139.211] by server-7.bemta-5.messagelabs.com id ED/3B-03739-E5522555; Tue, 12 May 2015 16:07:58 +0000 X-Env-Sender: anil@recoil.org X-Msg-Ref: server-12.tower-206.messagelabs.com!1431446877!14443300!1 X-Originating-IP: [5.153.225.51] X-SpamReason: No, hits=0.2 required=7.0 tests=RCVD_ILLEGAL_IP X-StarScan-Received: X-StarScan-Version: 6.13.14; banners=-,-,- X-VirusChecked: Checked Received: (qmail 6551 invoked from network); 12 May 2015 16:07:57 -0000 Received: from bark.recoil.org (HELO bark.recoil.org) (5.153.225.51) by server-12.tower-206.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 12 May 2015 16:07:57 -0000 Received: from [10.0.0.96] (host81-149-102-120.in-addr.btopenworld.com [81.149.102.120]); by bark.recoil.org (OpenSMTPD) with ESMTPSA id d3d02f05; TLS version=TLSv1/SSLv3 cipher=ECDHE-RSA-AES256-SHA bits=256 verify=NO; Tue, 12 May 2015 17:07:57 +0100 (BST) Mime-Version: 1.0 (Mac OS X Mail 8.2 \(2098\)) From: Anil Madhavapeddy In-Reply-To: Date: Tue, 12 May 2015 17:07:57 +0100 Message-Id: <8380EC23-480F-44BA-AA20-FCF95779FA5C@recoil.org> References: <5549E190.7080505@somerandomidiot.com> <7A8FE72F-2BDC-4E72-A6DE-CA56379F7C20@recoil.org> <4382CFB50FD64AFDA863FB6244D3FEA5@erratique.ch> <32C35BEB-47BF-4BC6-ACBB-844A7D778BD4@recoil.org> To: Richard Mortier X-Mailer: Apple Mail (2.2098) Cc: "mirageos-devel@lists.xenproject.org" Subject: Re: [MirageOS-devel] Logging (was: test, quality, tcpip) 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 12 May 2015, at 17:04, Richard Mortier wrote: > >>> >>> + within each component branch, there is a hierarchy of subordinate >>> branches, branching each time a message appears at a lower (finer >>> grained) debug level >> >> And this doesn't :) > > I was trying to capture the sequencing in the branching structure > rather than requiring reconstruction based on timestamps.

For example, can I use Lwt_unix.sleep? Correct; you cannot use Unix, Lwt_unix, etc. In Mirage, you can use OS.Time.sleep instead of Lwt_unix.sleep. Sometimes an existing library can be modified easily (e.g. by moving non-Unix code into a separate "core" module), so it might be worth trying that first. You should also try to avoid using C libraries where possible. e.g. you'd want to replace curl with cohttp here. > 2. Since the unikernel needs to make HTTPS request, I'd like to try out > OCaml-TLS.

Thank you for the suggestions.

I design my library using functor and start to appreciate how functor = helps to abstract design and easily target different backend (Unix, Xen).= =C2=A0

I still have two questions which are related to OS dependency.

1. How could I know if a library has any OS dependency=3F Do I need to= read their source code, or there is a easier way I don=E2=80=99t = know=3F

2. Is there any good crypto library (e.g. generating nonce, = calculating HMAC=5FSHA1) that can be used on Mirage=3F I am using Cryptokit= on my unix machine. It seems like I cannot use it in Mirage. Reason is = here (https://github.com/msimon/cryptokit/blob/master/src/cryptokit.= mli#L233). You may realize this problem is actually the reason I asked my = first question.=C2=A0

Thank you!

Correct; you cannot use Unix, Lwt=5Funix, etc. In Mirage, you can = use
OS.Time.sleep instead of Lwt=5Funix.sleep.

Sometimes an existing library can be modified easily (e.g. by = moving
non-Unix code into a separate =22core=22 module), so it might be worth
trying that first.

You should also try to avoid using C libraries where possible. e.g.=
you'd want to replace curl with cohttp here.

There are some examples in the tls repository:

https://github.com/mirleft/ocaml-tls/tree/master/mirage/example

I think there will be more information soon, as I see various
TLS-related releases being prepared.

Thank you for the suggestions.

I design my library using functor and start to appreciate how functor = helps to abstract design and easily target different backend (Unix, Xen).= =C2=A0

I still have two questions which are related to OS dependency.

1. How could I know if a library has any OS dependency=3F Do I need to= read their source code, or there is a easier way I don=E2=80=99t = know=3F

2. Is there any good crypto library (e.g. generating nonce, = calculating HMAC=5FSHA1) that can be used on Mirage=3F I am using Cryptokit= on my unix machine. It seems like I cannot use it in Mirage. Reason is = here (https://github.com/msimon/cryptokit/blob/master/src/cryptokit.= mli#L233). You may realize this problem is actually the reason I asked my = first question.=C2=A0

Thank you!

Correct; you cannot use Unix, Lwt=5Funix, etc. In Mirage, you can = use
OS.Time.sleep instead of Lwt=5Funix.sleep.

Sometimes an existing library can be modified easily (e.g. by = moving
non-Unix code into a separate =22core=22 module), so it might be worth
trying that first.

You should also try to avoid using C libraries where possible. e.g.=
you'd want to replace curl with cohttp here.

There are some examples in the tls repository:

https://github.com/mirleft/ocaml-tls/tree/master/mirage/example

I think there will be more information soon, as I see various
TLS-related releases being prepared.

The CPU of the Allwinner R8 is an ARM Cortex-A8, so the question transits to the Xen support for Cortex-A8. Btw, is there a list somewhere that summarises the Xen support for the various ARM processors? Most SBCs these days are based on Cortex-A7 (low-end ones line the RPi2), Cortex-A9 (mid-end ones like the Cubox-i family or Radxa Rock Pro), or Cortex-A15 or even Cortex-A17 (for higher-end ones like the Radxa 2). I think the A7 and A17 work with Xen, but not the other ones (but I may be wrong).

The goal is to have the file contents (once expanded on the filesystem) serialised as the raw string, not at the string with a prefix. While I agree that this breaks composability, I'm not sure how to fix it properly. I'd probably wrap the contents in Ir_slice.t into something that make bin-prot happy. I've moved the bug is tracked to the issue tracker[1]. Note that the HTTP client/server code is using to_json/of_json to exchange slices, so they don't hit that bug. Would be nice to have a binary RPC backend exercising this code path. That might be an interesting project if ones want to learn about Irmin API (see [2]).

The unikernel will just be sitting blocked when there's no IO, so this is accurate. Memory can be obtained via the OCaml GC module; Mindy's reply has a link to the easy way to use it to generate HTML. A more subtle question: are you trying to get this information from *within* the unikernel to alter its behaviour in response to load? In that case you'll need a slightly more sophisticated way to measure CPU usage from within the VM. -anil > On 18 May 2015, at 10:56, Masoud Koleini wrote: > > Hi all, > > Is the any way for a Mirage unikernel to get its CPU and memory utilisation? > > Thanks. > > > > > > > This message and any attachment are intended solely for the addressee > and may contain confidential information.

Rumprun provides a unikernel stack with a POSIXy (NetBSD-HEAD) userspace and can run on Xen, QEMU/KVM, bare metal and POSIX userspace. The resulting Mirage + rumprun unikernel will thus be able to run on all of the platforms rumprun supports. The first step to get this working is building an OCaml cross compiler that uses the rumprun cross compiler as its backend for building C code and linking. I've researched the various cross-compilation options for OCaml and for now have based my code off the approach used by Peter Zotov in his `opam-android' repository[2]. My work in progress OPAM repository is here: https://github.com/mato/opam-rumprun This is enough to get an OCaml "Hello, World" running on rumprun, and I've also tested that the Unix package works as expected. So far so good. However, in order to get Mirage to compile, I need to cross-compile Lwt and that does not work as expected: $ OCAMLFIND_TOOLCHAIN=rumprun ocaml setup.ml -configure --prefix /home/mato/.opam/system/x86_64-rumprun-netbsd/ --disable-libev Results in: not checking for pkg-config not checking for libev testing for pthread: ........................... unavailable not checking for glib The following recquired C libraries are missing: pthread. The reason this happens is that discover.ml is invoking the following compile command: /home/mato/projects/rumpkernel/rumprun/app-tools/rumprun-xen-cc -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -I/usr/include -o /tmp/lwt_stubf12ac7.o -I/home/mato/.opam/system/x86_64-rumprun-netbsd/lib/ocaml /tmp/lwt_stubf12ac7.c Note the inclusion of -I/usr/include -- this is presumably there so that the system OCaml compiler's headers are available, however it results in a conflict between the NetBSD headers provided by rumprun and the system headers. What can be done to fix the above? Should I be using a host compiler built and installed by OPAM rather than the system compiler (4.02.1-1ppa3~precise on Debian wheezy). [I'll try this and see if it helps...] I tried to hack around the problem by using --enable-android-target, that causes discover.ml to succeed and the build then proceeds, failing on a different problem: E: Failure("Expected built file '_build/src/unix/dlllwt-unix_stubs.so' doesn't exist.") This is expected; the rumprun toolchain does not support dynamic linking and I have configured the ocaml-rumprun compiler with -no-shared-libs. Is there some way to tell OASIS to not expect any shared libraries to be built? General questions: 1) Is this the right strategy for building an OCaml cross-compiler and integrating with OPAM? AFAICS there are multiple approaches being used in the wild and OCaml upstream *claims* to include support for cross-compiling via -host and -target, however that support is not actually functional? For the rumprun support to be as user-friendly as possible, we need an easy way of switching the backend rumprun cross-compiler and linker used by ocaml when the user wants to switch platforms or architectures. The approach used by the android repository I based my work off implies either: a) the user would have to *reinstall* the cross compiler (specifying eg. RUMPRUN_CC in the environment) and all packages using native code whenever they want to switch the backend compiler. b) we would have to provide different opam packages of the compiler and native libraries (Lwt) for each platform/arch combination supported by rumprun. This is unmanageable. 2) Is there an easy way to switch ocamlc and the various other parts of the build system(s) involved into a verbose mode so that I can see what compilers are being invoked and why they fail? At the moment I'm using `strace' for this :-/ All ideas and help much appreciated, Cheers, Martin [1] http://wiki.rumpkernel.org/Repo%3A-rumprun [2] https://github.com/whitequark/opam-android _______________________________________________ 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 May 19 08:48:28 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Tue, 19 May 2015 08:48:28 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YudCH-0004Qk-7q; Tue, 19 May 2015 08:48:21 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YudCG-0004Qe-2w for mirageos-devel@lists.xenproject.org; Tue, 19 May 2015 08:48:20 +0000 Received: from [85.158.137.68] by server-2.bemta-3.messagelabs.com id 21/55-03079-3D8FA555; Tue, 19 May 2015 08:48:19 +0000 X-Env-Sender: martin@lucina.net X-Msg-Ref: server-12.tower-31.messagelabs.com!1432025298!11727559!1 X-Originating-IP: [62.176.169.44] X-SpamReason: No, hits=0.0 required=7.0 tests= X-StarScan-Received: X-StarScan-Version: 6.13.15; banners=-,-,- X-VirusChecked: Checked Received: (qmail 26567 invoked from network); 19 May 2015 08:48:18 -0000 Received: from smtp.lucina.net (HELO smtp.lucina.net) (62.176.169.44) by server-12.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 19 May 2015 08:48:18 -0000 Received: from nodbug.lucina.net (chello089173222227.chello.sk [89.173.222.227]) by smtp.lucina.net (Postfix) with ESMTPSA id E2AB1122811; Tue, 19 May 2015 10:47:31 +0200 (CEST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=lucina.net; s=dkim-201309; t=1432025251; bh=GvzF60nKSBieKUvpw9suamLFg8P3UWB+7kP4u5ERHeI=; h=Date:From:To:Cc:Subject:From; b=YDFCFJ4VmjyABeXmj64+n79R2o5xf+cPSDv7SJezradX8O0OgvkeMCsdlEwKCeiTY y+GiafsWGutWs638yX3XRP9ddgNL53zFpAO6F1FLi72JJ81pU3VBhrjsWdFCrDYf/Q +w7BHIyG06T9ZbyZfmgjhCYJpeloDtaZLV+0WjlSfEC7PkZIHuTpyB+bsm2xJwvOHa JwruMv6XQSQSTk2quJEtxtWyvNXeb/sKIYURhdL+Uc7IxvKjUi3y4pGR9emq3hg0dS 8fd0y507JjYZuxGIX/PZ+QukC+timN9TrdfklEjLXZeCvp6Y8LENXmyx5dBCRaAjFa gepWtdRrfroDg== Received: by nodbug.lucina.net (Postfix, from userid 1000) id 309154C0E2C; Tue, 19 May 2015 10:48:30 +0200 (CEST) Date: Tue, 19 May 2015 10:48:30 +0200 From: Martin Lucina To: mirageos-devel@lists.xenproject.org Message-ID: <20150519084830.GA10420@nodbug.lucina.net> Mail-Followup-To: mirageos-devel@lists.xenproject.org, opam-devel@lists.xenproject.org, Anil Madhavapeddy , Peter Zotov MIME-Version: 1.0 Content-Disposition: inline User-Agent: Mutt/1.5.21 (2010-09-15) Cc: opam-devel@lists.xenproject.org, Peter Zotov , Anil Madhavapeddy Subject: [MirageOS-devel] Cross-compiling OCaml, Mirage OS for rumprun, OPAM integration 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'm working on getting OCaml and Mirage OS running on top of the rumprun unikernel stack[1].

Rumprun provides a unikernel stack with a POSIXy (NetBSD-HEAD) userspace and can run on Xen, QEMU/KVM, bare metal and POSIX userspace. The resulting Mirage + rumprun unikernel will thus be able to run on all of the platforms rumprun supports. The first step to get this working is building an OCaml cross compiler that uses the rumprun cross compiler as its backend for building C code and linking. I've researched the various cross-compilation options for OCaml and for now have based my code off the approach used by Peter Zotov in his `opam-android' repository[2]. My work in progress OPAM repository is here: https://github.com/mato/opam-rumprun This is enough to get an OCaml "Hello, World" running on rumprun, and I've also tested that the Unix package works as expected. So far so good. However, in order to get Mirage to compile, I need to cross-compile Lwt and that does not work as expected: $ OCAMLFIND_TOOLCHAIN=rumprun ocaml setup.ml -configure --prefix /home/mato/.opam/system/x86_64-rumprun-netbsd/ --disable-libev Results in: not checking for pkg-config not checking for libev testing for pthread: ........................... unavailable not checking for glib The following recquired C libraries are missing: pthread. The reason this happens is that discover.ml is invoking the following compile command: /home/mato/projects/rumpkernel/rumprun/app-tools/rumprun-xen-cc -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -I/usr/include -o /tmp/lwt_stubf12ac7.o -I/home/mato/.opam/system/x86_64-rumprun-netbsd/lib/ocaml /tmp/lwt_stubf12ac7.c Note the inclusion of -I/usr/include -- this is presumably there so that the system OCaml compiler's headers are available, however it results in a conflict between the NetBSD headers provided by rumprun and the system headers. What can be done to fix the above? Should I be using a host compiler built and installed by OPAM rather than the system compiler (4.02.1-1ppa3~precise on Debian wheezy). [I'll try this and see if it helps...] I tried to hack around the problem by using --enable-android-target, that causes discover.ml to succeed and the build then proceeds, failing on a different problem: E: Failure("Expected built file '_build/src/unix/dlllwt-unix_stubs.so' doesn't exist.") This is expected; the rumprun toolchain does not support dynamic linking and I have configured the ocaml-rumprun compiler with -no-shared-libs. Is there some way to tell OASIS to not expect any shared libraries to be built? General questions: 1) Is this the right strategy for building an OCaml cross-compiler and integrating with OPAM? AFAICS there are multiple approaches being used in the wild and OCaml upstream *claims* to include support for cross-compiling via -host and -target, however that support is not actually functional? For the rumprun support to be as user-friendly as possible, we need an easy way of switching the backend rumprun cross-compiler and linker used by ocaml when the user wants to switch platforms or architectures. The approach used by the android repository I based my work off implies either: a) the user would have to *reinstall* the cross compiler (specifying eg.

Rumprun provides a unikernel stack with a POSIXy (NetBSD-HEAD) userspace and can run on Xen, QEMU/KVM, bare metal and POSIX userspace. The resulting Mirage + rumprun unikernel will thus be able to run on all of the platforms rumprun supports. The first step to get this working is building an OCaml cross compiler that uses the rumprun cross compiler as its backend for building C code and linking. I've researched the various cross-compilation options for OCaml and for now have based my code off the approach used by Peter Zotov in his `opam-android' repository[2]. My work in progress OPAM repository is here: https://github.com/mato/opam-rumprun This is enough to get an OCaml "Hello, World" running on rumprun, and I've also tested that the Unix package works as expected. So far so good. However, in order to get Mirage to compile, I need to cross-compile Lwt and that does not work as expected: $ OCAMLFIND_TOOLCHAIN=rumprun ocaml setup.ml -configure --prefix /home/mato/.opam/system/x86_64-rumprun-netbsd/ --disable-libev Results in: not checking for pkg-config not checking for libev testing for pthread: ........................... unavailable not checking for glib The following recquired C libraries are missing: pthread. The reason this happens is that discover.ml is invoking the following compile command: /home/mato/projects/rumpkernel/rumprun/app-tools/rumprun-xen-cc -fno-defer-pop -Wall -D_FILE_OFFSET_BITS=64 -D_REENTRANT -c -I/usr/include -o /tmp/lwt_stubf12ac7.o -I/home/mato/.opam/system/x86_64-rumprun-netbsd/lib/ocaml /tmp/lwt_stubf12ac7.c Note the inclusion of -I/usr/include -- this is presumably there so that the system OCaml compiler's headers are available, however it results in a conflict between the NetBSD headers provided by rumprun and the system headers. What can be done to fix the above? Should I be using a host compiler built and installed by OPAM rather than the system compiler (4.02.1-1ppa3~precise on Debian wheezy). [I'll try this and see if it helps...] I tried to hack around the problem by using --enable-android-target, that causes discover.ml to succeed and the build then proceeds, failing on a different problem: E: Failure("Expected built file '_build/src/unix/dlllwt-unix_stubs.so' doesn't exist.") This is expected; the rumprun toolchain does not support dynamic linking and I have configured the ocaml-rumprun compiler with -no-shared-libs. Is there some way to tell OASIS to not expect any shared libraries to be built? General questions: 1) Is this the right strategy for building an OCaml cross-compiler and integrating with OPAM? AFAICS there are multiple approaches being used in the wild and OCaml upstream *claims* to include support for cross-compiling via -host and -target, however that support is not actually functional? For the rumprun support to be as user-friendly as possible, we need an easy way of switching the backend rumprun cross-compiler and linker used by ocaml when the user wants to switch platforms or architectures. The approach used by the android repository I based my work off implies either: a) the user would have to *reinstall* the cross compiler (specifying eg. RUMPRUN_CC in the environment) and all packages using native code whenever they want to switch the backend compiler. b) we would have to provide different opam packages of the compiler and native libraries (Lwt) for each platform/arch combination supported by rumprun. This is unmanageable. 2) Is there an easy way to switch ocamlc and the various other parts of the build system(s) involved into a verbose mode so that I can see what compilers are being invoked and why they fail?

In this talk, we will describe an alternative to network simulators and emulators by using several OCaml libraries to build a persistent, interactive network stack from off-the-shelf OCaml libraries that are present in OPAM. Irmin (the database that never forgets) presents users with an API allowing DVCS-like access to ordinary program data [1]. Using Irmin, we can construct data structures that are commonly found in network protocols (such as distributed hash tables), and manipulate them across nodes via DVCS pull/push/merge operations. MirageOS [2] is a library operating system written in OCaml where all structures are ordinary program data, even ones that normally live deep within the kernel in traditional architectures. Mirage provides a network stack that provides a complete TCP/IP implementation, including Ethernet, ARP, ICMP, IP, UDP, TCP, and DHCP. We combine both Irmin and the existing MirageOS stack to build a persistent network stack. With Irmin, we can manage updates for structures like the ARP cache, which is mutated by both incoming network traffic and the passage of time, with clear semantics, history, and conflict resolution. It also becomes possible, through Irmin's sync interface or Git filesystem backend, to make this data persistent in a consistent and convenient way. Using Irmin's Git filesystem backend, it's also possible to interact with this data with Git tools. One can, for example, examine the history of the cache with `gitk` and observe whether an expiration thread is correctly removing old entries on its branch. It's even possible to make edits to the serialized cache data and commit them from the command line, resulting in live changes to the cache! From an implemented example of an ARP cache, we'll motivate further possibilities in more complicated protocols and their related data stores, including TCP and its associated state. We will also discuss potential future uses in the context of many MirageOS unikernels running in a hypervisor, including coordination that traditionally uses broadcast traffic across a local area network.

[I'll try this and see if it helps...] No. This is an issue with Lwt's discover.ml script.

Nope. OASIS is painfully inflexible, especially when cross-compiling. You can probably patch setup.ml so that it thinks that the current OCaml is built without dynlink, but this is package-specific. > > General questions: > > 1) Is this the right strategy for building an OCaml cross-compiler and > integrating with OPAM? > > AFAICS there are multiple approaches being used in the wild and OCaml > upstream *claims* to include support for cross-compiling via -host and > -target, however that support is not actually functional?

Turns out it's a two-line patch, at least in the case of Lwt: https://github.com/mato/opam-rumprun/commit/3d3a9f0b46a21370c7b619e14cbfdde= c90acf433 > >AFAICS there are multiple approaches being used in the wild and OCaml > >upstream *claims* to include support for cross-compiling via -host and > >-target, however that support is not actually functional? > = > Cross-compiling is not there yet.

This is what opam-android uses. And, as I just found out now, it's not just the native packages, it's *all* packages that need to be rebuilt. So, for Mirage I'd have to produce -rumprun variants of all its dependent packages, right? This would include teaching the "mirage configure" script about them. This begs the question, why did you use the approach of building the cross-compiler as a normal OPAM package, rather than as a compiler package? If I understand correctly how "OPAM switch" works, then the latter option would at least get rid of the need to deal with the -android (or -rumprun) renaming of packages since each compiler has its own set of packages. Obviously, there'd still have to be some way of getting the OCAMLFIND_TOOLCHAIN and/or other cross-compilation patches into the system but at first glance it seems like it would be more flexible than adding suffixes to package names. Thoughts?

Because the cross-compiler needs a normal compiler (and its runtime) to build and execute. Because many packages (from camlp4 to ppx) depend on build-time components that execute on the host arch.

We already partly do that to cross-compile the C stubs for Xen (such as gmp for the TLS stack to work on Xen). The upcoming 2.5.0 release of mirage will have improved support for this. See gmp-xen[1] and some ugly ocamlfind hackery to pass the right options at link time, used by mirage configure[2] when generating the Makefile. Clearly the situation will not scale well as we will have to patch every package using C stubs.

In the 4.02.1 INSTALL file[1], which documents a "-target"= option and says
it will produce a cross-compiler.=C2=A0 The switch is even accepted by
configure, but the guts don't actually work.

Perhaps some commit snuck in to 4.02.1 which shouldn't have?

Indeed, this seems to be a side-effect of the partial merg= e of Adrien Nader's patches; he was working on cross-compilation in tru= nk between releases 4.01 and 4.02.

In the 4.02.1 INSTALL file[1], which documents a "-target"= option and says

configure, but the guts don't actually work.

Perhaps some commit snuck in to 4.02.1 which shouldn't have?

I think that's a good think. Sorry to spam the list again. This obviously won't be as easy as it could be in mirage-decks as we are using the cow syntax extension in various places. So to fix you bug, you might want to edit the SYNTAX flag in the Makefile to add ": -syntax(camlp4o)" (similar to "static*.*" one). This will tell ocamlbuild to not use camlp4 on that file.

I think that's a good think. Sorry to spam the list again. This obviously won't be as easy as it could be in mirage-decks as we are using the cow syntax extension in various places. So to fix you bug, you might want to edit the SYNTAX flag in the Makefile to add ": -syntax(camlp4o)" (similar to "static*.*" one). This will tell ocamlbuild to not use camlp4 on that file.

Le=C2=A0mar. 19 mai 201= 5 =C3=A0=C2=A010:50, Martin Lucina <martin@lucina.net> a =C3=A9crit=C2=A0:
[Re-sending with correct opam-devel address]

Hi all,

I'm working on getting OCaml and Mirage OS running on top of the rumpru= n
unikernel stack[1].

Rumprun provides a unikernel stack with a POSIXy (NetBSD-HEAD) userspace and can run on Xen, QEMU/KVM, bare metal and POSIX userspace.=C2=A0 The
resulting Mirage + rumprun unikernel will thus be able to run on all of the=
platforms rumprun supports.

The first step to get this working is building an OCaml cross compiler that=
uses the rumprun cross compiler as its backend for building C code and
linking.

I've researched the various cross-compilation options for OCaml and for= now
have based my code off the approach used by Peter Zotov in his
`opam-android' repository[2].

My work in progress OPAM repository is here:

https://= github.com/mato/opam-rumprun

This is enough to get an OCaml "Hello, World" running on rumprun,= and I've
also tested that the Unix package works as expected. So far so good.

However, in order to get Mirage to compile, I need to cross-compile Lwt and=
that does not work as expected:

=C2=A0 =C2=A0 $ OCAMLFIND_TOOLCHAIN=3Drumprun ocaml setup.ml -configure --prefix /home/mato/.opam/sy= stem/x86_64-rumprun-netbsd/ --disable-libev

Results in:

=C2=A0 =C2=A0 not checking for pkg-config
=C2=A0 =C2=A0 not checking for libev
=C2=A0 =C2=A0 testing for pthread: ........................... unavailable<= br> =C2=A0 =C2=A0 not checking for glib

=C2=A0 =C2=A0 The following recquired C libraries are missing: pthread.

The reason this happens is that discover.ml is invoking the following
compile command:

/home/mato/projects/rumpkernel/rumprun/app-tools/rumprun-xen-cc -fno-defer-= pop -Wall -D_FILE_OFFSET_BITS=3D64 -D_REENTRANT -c -I/usr/include -o /tmp/l= wt_stubf12ac7.o -I/home/mato/.opam/system/x86_64-rumprun-netbsd/lib/ocaml /= tmp/lwt_stubf12ac7.c

Note the inclusion of -I/usr/include -- this is presumably there so that the system OCaml compiler's headers are available, however it results i= n a
conflict between the NetBSD headers provided by rumprun and the system
headers.

What can be done to fix the above? Should I be using a host compiler built<= br> and installed by OPAM rather than the system compiler (4.02.1-1ppa3~precise=
on Debian wheezy). [I'll try this and see if it helps...]

I tried to hack around the problem by using --enable-android-target, that causes discover.ml to = succeed and the build then proceeds, failing on a
different problem:

E: Failure("Expected built file '_build/src/unix/dlllwt-unix_stubs= .so' doesn't exist.")

This is expected; the rumprun toolchain does not support dynamic linking and I have configured the ocaml-rumprun compiler with -no-shared-libs. Is there some way to tell OASIS to not expect any shared libraries to be
built?

I suppose it will require to pat= ch src/oasis/OASISLibrary l201 to have ext_lib be an option rather than a s= tring. OASIS can be forked and PR sent on github, feel free to send a PR ab= out that.
=C2=A0

General questions:

1) Is this the right strategy for building an OCaml cross-compiler and
integrating with OPAM?

AFAICS there are multiple approaches being used in the wild and OCaml
upstream *claims* to include support for cross-compiling via -host and
-target, however that support is not actually functional?

For the rumprun support to be as user-friendly as possible, we need an easy=
way of switching the backend rumprun cross-compiler and linker used by
ocaml when the user wants to switch platforms or architectures. The
approach used by the android repository I based my work off implies either:=

a) the user would have to *reinstall* the cross compiler (specifying eg. RUMPRUN_CC in the environment) and all packages using native code whenever<= br> they want to switch the backend compiler.

b) we would have to provide different opam packages of the compiler and
native libraries (Lwt) for each platform/arch combination supported by
rumprun. This is unmanageable.

2) Is there an easy way to switch ocamlc and the various other parts of the=
build system(s) involved into a verbose mode so that I can see what
compilers are being invoked and why they fail? At the moment I'm using<= br> `strace' for this :-/

All ideas and help much appreciated,

Cheers,

Martin

Le=C2=A0mar. 19 mai 201= 5 =C3=A0=C2=A010:50, Martin Lucina <martin@lucina.net> a =C3=A9crit=C2=A0:
[Re-sending with correct opam-devel address]

Hi all,

I'm working on getting OCaml and Mirage OS running on top of the rumpru= n
unikernel stack[1].

Rumprun provides a unikernel stack with a POSIXy (NetBSD-HEAD) userspace and can run on Xen, QEMU/KVM, bare metal and POSIX userspace.=C2=A0 The
resulting Mirage + rumprun unikernel will thus be able to run on all of the=
platforms rumprun supports.

The first step to get this working is building an OCaml cross compiler that=
uses the rumprun cross compiler as its backend for building C code and
linking.

I've researched the various cross-compilation options for OCaml and for= now
have based my code off the approach used by Peter Zotov in his
`opam-android' repository[2].

My work in progress OPAM repository is here:

https://= github.com/mato/opam-rumprun

This is enough to get an OCaml "Hello, World" running on rumprun,= and I've
also tested that the Unix package works as expected. So far so good.

However, in order to get Mirage to compile, I need to cross-compile Lwt and=
that does not work as expected:

=C2=A0 =C2=A0 $ OCAMLFIND_TOOLCHAIN=3Drumprun ocaml setup.ml -configure --prefix /home/mato/.opam/sy= stem/x86_64-rumprun-netbsd/ --disable-libev

Results in:

=C2=A0 =C2=A0 not checking for pkg-config
=C2=A0 =C2=A0 not checking for libev
=C2=A0 =C2=A0 testing for pthread: ........................... unavailable<= br> =C2=A0 =C2=A0 not checking for glib

=C2=A0 =C2=A0 The following recquired C libraries are missing: pthread.

The reason this happens is that discover.ml is invoking the following
compile command:

/home/mato/projects/rumpkernel/rumprun/app-tools/rumprun-xen-cc -fno-defer-= pop -Wall -D_FILE_OFFSET_BITS=3D64 -D_REENTRANT -c -I/usr/include -o /tmp/l= wt_stubf12ac7.o -I/home/mato/.opam/system/x86_64-rumprun-netbsd/lib/ocaml /= tmp/lwt_stubf12ac7.c

Note the inclusion of -I/usr/include -- this is presumably there so that the system OCaml compiler's headers are available, however it results i= n a
conflict between the NetBSD headers provided by rumprun and the system
headers.

What can be done to fix the above? Should I be using a host compiler built<= br> and installed by OPAM rather than the system compiler (4.02.1-1ppa3~precise=
on Debian wheezy). [I'll try this and see if it helps...]

I tried to hack around the problem by using --enable-android-target, that causes discover.ml to = succeed and the build then proceeds, failing on a
different problem:

E: Failure("Expected built file '_build/src/unix/dlllwt-unix_stubs= .so' doesn't exist.")

This is expected; the rumprun toolchain does not support dynamic linking and I have configured the ocaml-rumprun compiler with -no-shared-libs. Is there some way to tell OASIS to not expect any shared libraries to be
built?

I suppose it will require to pat= ch src/oasis/OASISLibrary l201 to have ext_lib be an option rather than a s= tring. OASIS can be forked and PR sent on github, feel free to send a PR ab= out that.
=C2=A0

General questions:

1) Is this the right strategy for building an OCaml cross-compiler and
integrating with OPAM?

AFAICS there are multiple approaches being used in the wild and OCaml
upstream *claims* to include support for cross-compiling via -host and
-target, however that support is not actually functional?

For the rumprun support to be as user-friendly as possible, we need an easy=
way of switching the backend rumprun cross-compiler and linker used by
ocaml when the user wants to switch platforms or architectures. The
approach used by the android repository I based my work off implies either:=

a) the user would have to *reinstall* the cross compiler (specifying eg. RUMPRUN_CC in the environment) and all packages using native code whenever<= br> they want to switch the backend compiler.

b) we would have to provide different opam packages of the compiler and
native libraries (Lwt) for each platform/arch combination supported by
rumprun. This is unmanageable.

2) Is there an easy way to switch ocamlc and the various other parts of the=
build system(s) involved into a verbose mode so that I can see what
compilers are being invoked and why they fail? At the moment I'm using<= br> `strace' for this :-/

All ideas and help much appreciated,

Cheers,

Martin

I saw these sorts of segmentation faults due to bad memory on one of my first Cubieboards.

Getting further through the list of Mirage dependencies, trying to get
sexplib building for rumprun hits another different problem with OASIS:

I use the following commands to build sexplib-rumprun, similar to what the<= br> android build does:

=C2=A0 ["ocaml" "setup.ml" "-configure" "--prefix" "${p= refix}/x86_64-rumprun-netbsd" "--disable-syntax"]
=C2=A0 ["ocamlbuild" "-use-ocamlfind" "-just-plugi= n"]
=C2=A0 ["env" "OCAMLFIND_TOOLCHAIN=3Drumprun" "oca= ml" "setup.ml&q= uot; "-build"]
=C2=A0 ["env" "OCAMLFIND_TOOLCHAIN=3Drumprun" "oca= ml" "setup.ml&q= uot; "-install"]
=C2=A0 ["find" sexplib:lib "-name" "pa_sexp_conv.*= " "-exec" "ln" "-sf" "{}" &quo= t;%{prefix}%/x86_64-rumprun-netbsd/lib/sexplib/" ";"] { type= _conv-rumprun:installed }

Now, sexplib tries to build a .cmxs which won't work with the rumprun toolchain, so I've patched its setup.ml to force native_dynlink to be
false:

https://github.com/mato/opam-rumprun/blob/master/packages/sexplib-rum= prun.112.24.01/files/patches/oasis-disable-dynlink.patch


I think it would be far easier to add = '--override native_dynlink false' to the configure step.
= =C2=A0
The problem I'm seeing is that if I run "opam install sexplib-rump= run
--verbose", it fails in the setup.ml -install setup with a stack overflow:

- Installed /home/mato/.opam/system/x86_64-rumprun-netbsd/lib/sexplib_unix/= sexplib_unix.cmx
- Installed /home/mato/.opam/system/x86_64-rumprun-netbsd/lib/sexplib_unix/= META
- E: Stack overflow
[ERROR] The compilation of sexplib-rumprun failed at "env
=C2=A0 =C2=A0 =C2=A0 =C2=A0 OCAMLFIND_TOOLCHAIN=3Drumprun ocaml setup.ml -install".

However: If I run the OPAM build commands from a shell in the build
directory for sexplib, the install step works fine.

Any ideas?

Now, sexplib tries to build a .cmxs which won't work with the rumprun toolchain, so I've patched its setup.ml to force native_dynlink to be
false:

https://github.com/mato/opam-rumprun/blob/master/packages/sexplib-rum= prun.112.24.01/files/patches/oasis-disable-dynlink.patch


I think it would be far easier to add = '--override native_dynlink false' to the configure step.
= =C2=A0
The problem I'm seeing is that if I run "opam install sexplib-rump= run
--verbose", it fails in the setup.ml -install setup with a stack overflow:

- Installed /home/mato/.opam/system/x86_64-rumprun-netbsd/lib/sexplib_unix/= sexplib_unix.cmx
- Installed /home/mato/.opam/system/x86_64-rumprun-netbsd/lib/sexplib_unix/= META
- E: Stack overflow
[ERROR] The compilation of sexplib-rumprun failed at "env
=C2=A0 =C2=A0 =C2=A0 =C2=A0 OCAMLFIND_TOOLCHAIN=3Drumprun ocaml setup.ml -install".

However: If I run the OPAM build commands from a shell in the build
directory for sexplib, the install step works fine.

Any ideas?

Andrew, if you're seeing the site hanging for some connections, this may be due to some of the retransmit timer settings in the TCP stack due to you coming in from a high latency high bandwidth connection. I'm planning to setup a permanent pcap trace on the live mirage.io site so that we can debug and trace through these issues a lot more easily. If you can get us a pcap trace of a hang from one of your servers, that would be most helpful in tracking this down. cheers, Anil > On 21 May 2015, at 10:11, Nick Betteridge wrote: > > Hi Amir, > > Well, I was actually trying to read http://openmirage.org/blog/intro-tcpip as I was initially trying to get some of the skeleton examples to work. > > The above link didn't work, but does now.

What I'd like to get to is being able to build systems which use the best of both worlds. For example, have a Mirage unikernel serve TLS and/or HTTP, and talk FastCGI to a PHP backend running on a rumprun unikernel. The other interesting aspect is using Jitsu [1] to spawn just-in-time unikernels on demand. This would let you have a bunch of unikernels which are dormant and are only booted when the service they provide is actually accessed.

Hi

I've been trying to ru= n two unikernals on the cubieboard=2C but each time I try and xl create the= second one=2C it always comes up with the following error:

sudo xl = create www.xl
Parsing config from www.xl
libxl: notice: libxl_numa.c:= 494:libxl__get_numa_candidate: NUMA placement failed=2C performance might b= e affected

If I destroy the first=2C r= unning unikernel and then reverse the order of creation=2C the same error w= ill occur again on the second create.

Does anyone have any ideas on = this?

Hi

I've been trying to ru= n two unikernals on the cubieboard=2C but each time I try and xl create the= second one=2C it always comes up with the following error:

sudo xl = create www.xl
Parsing config from www.xl
libxl: notice: libxl_numa.c:= 494:libxl__get_numa_candidate: NUMA placement failed=2C performance might b= e affected
xc: error: panic: xc_dom_boot.c:191: xc_dom_boot_domU_map: fa= iled to mmap domU pages 0x88000+0x1 [mmap=2C errno=3D14 (Bad address)]: Int= ernal error
libxl: error: libxl_dom.c:427:libxl__build_pv: xc_dom_build_= image failed: Bad address
libxl: error: libxl_create.c:1022:domcreate_re= build_done: cannot (re-)build domain: -3

If I destroy the first=2C r= unning unikernel and then reverse the order of creation=2C the same error w= ill occur again on the second create.

Does anyone have any ideas on = this?

Cheers

My talk is g= oing to be quite high-level, and focus on my experiences and motivations fo= r wanting to learn about MirageOS, as well as showing off various cool proj= ects (Jitsu springs to mind) that will hopefully encourages others to explo= re MirageOS. Anyway, I hope this is an acceptable topic for a beginner like= me to talk about! If it's OK, I might run a few of the slides (*) past= the list. Looking forward to meeting some of you on the 21st.
thanks,

Matt

(*) which hopefully will be hosted using Mirage!

I'm going to get = them up and running as a mirage-seal (or otherwise Mirage OS) website = somewhere soon as well, and write about how that went.

Nice to meet a some of = you on Thursday!

Hello all,

The = event page is here: http://www.meetup.com/devs-in-the-ditch/events/221972483/ = , I can see a few familiar names from this list have already signed = up.

My talk is = going to be quite high-level, and focus on my experiences and = motivations for wanting to learn about MirageOS, as well as showing off = various cool projects (Jitsu springs to mind) that will hopefully = encourages others to explore MirageOS.

Looking forward to = meeting some of you on the 21st.

thanks,

Matt

(*) which hopefully will be hosted = using Mirage!

This other reason is the one I see as the extremely interesting one. It's curious, the longer the current implementation provided by rump kernels (*) stays useful, the more disappointed I am since we have failed to provide better options to legacy software. That said, even with newer languages existing, I will be extremely surprised if the current implementation will be obsolete in 10 or even 20 years -- the Tarzan who rewrites everything in safe languages in production quality simply doesn't exist. I do hope people try to prove me wrong, though either way I win: either I'm right, or I have vastly better software at my fingertips. For users, these types of synergies are truly exciting: being able to ride the wave of the latest omelette research while at all times having access to a fully equipped, working kitchen. Getting more users and deployers on board also gives us good feedback on which reality-derived problem/component is currently in most urgent need of a solution. *) the concept is generic, and I hope that future operatin^Wbottom layers of the software stack will retain separation between driver implementation and the environments the driver is usable in. _______________________________________________ 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 May 27 13:47:29 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Wed, 27 May 2015 13:47:29 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Yxbg1-00006E-OX; Wed, 27 May 2015 13:47:21 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1Yxbg0-00005P-CU for mirageos-devel@lists.xenproject.org; Wed, 27 May 2015 13:47:20 +0000 Received: from [85.158.137.68] by server-11.bemta-3.messagelabs.com id 80/4B-16518-7EAC5655; Wed, 27 May 2015 13:47:19 +0000 X-Env-Sender: pooka@rumpkernel.org X-Msg-Ref: server-10.tower-31.messagelabs.com!1432734439!13005488!1 X-Originating-IP: [130.233.192.7] X-SpamReason: No, hits=0.5 required=7.0 tests=BODY_RANDOM_LONG X-StarScan-Received: X-StarScan-Version: 6.13.15; banners=-,-,- X-VirusChecked: Checked Received: (qmail 2805 invoked from network); 27 May 2015 13:47:19 -0000 Received: from mail.cs.hut.fi (HELO mail.cs.hut.fi) (130.233.192.7) by server-10.tower-31.messagelabs.com with SMTP; 27 May 2015 13:47:19 -0000 Received: from [127.0.0.1] (mannerheim.cs.hut.fi [130.233.193.8]) by mail.cs.hut.fi (Postfix) with ESMTPS id A2DE8308C33; Wed, 27 May 2015 16:47:17 +0300 (EEST) Message-ID: <5565CAE4.9020005@rumpkernel.org> Date: Wed, 27 May 2015 13:47:16 +0000 From: Antti Kantee MIME-Version: 1.0 To: anil@recoil.org, Martin Lucina References: <20150522153559.GA11907@nodbug.lucina.net> <555F5685.2010909@rumpkernel.org> <20150522163357.GD11907@nodbug.lucina.net> In-Reply-To: Cc: rumpkernel-users@freelists.org, mirageos-devel@lists.xenproject.org, Anil Madhavapeddy , Richard Mortier Subject: Re: [MirageOS-devel] OCaml and Mirage now running on rumprun, including bare metal 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-Transfer-Encoding: 7bit Content-Type: text/plain; charset="us-ascii"; Format="flowed" Sender: mirageos-devel-bounces@lists.xenproject.org Errors-To: mirageos-devel-bounces@lists.xenproject.org On 24/05/15 16:41, Anil Madhavapeddy wrote: >>> Good show!

I was following the tutorial on openmirage, specifically at [1], when I faced a few problems at the Linux DomU part.

Hello,

I hope you're all having a w= onderful day.

I was following the tutorial on open= mirage, specifically at [1], when I faced a few problems at the Linux DomU = part.=C2=A0
The only differences between the tutorial and how I w= ent about it is in my choice for some variables i.e. hostname, ssh settings= , etc.=C2=A0
1- Using the "/root/dom0_kernel" zImage, r= unning xl create causes it to enter an endless loop. All I get back is:
```
mirage@cubietruck:/media/disk$ sudo xl create= domU_test -c
Parsing config from domU_test
```

'sudo xl list' shows that the guest is = in a paused state.=C2=A0
Unpausing it, the guest enters a sort of= limbo (no state present, just dashes).
```
mirage= @cubietruck:/media/disk$ sudo xl unpause Ubuntu-14.04

2- Compiling the linux kernel seperately using gcc-4.9 on= the CT, and changing the cfg file to use the zImage kernel instead I get t= he following error:
```
mirage@cubietruck:/media/d= isk$ sudo xl create -c XenGuest2.cfg

libxl: error: libxl_dm.c:1388:device_model_spawn_outcome: d= omain 5 device model: spawn failed (rc=3D-3)

libxl: error: libxl_dm.c:1492:kill_device_model: Device Model alrea= dy exited
```

Currently, my cfg fi= le looks like this:
```
device_model_version =3D &= quot;qemu-xen"
device_model_override =3D "/usr/bin/qemu= -arm-static"
kernel =3D "/media/disk/zImage"

vcpus =3D= 2
serial=3D"pty"
disk =3D [ 'phy:/media/= disk/XenGuest2.img,xvda1,w', 'phy:/media/disk/XenGuest2.swap,xvda2,= w']
vif =3D ['bridge=3Dxenbr0']
root =3D &q= uot;/dev/xvda1 ro"
#extra =3D 'console=3Dhvc0 xencons=3D= tty root=3D/dev/xvda1'
```
But I've messe= d with it quite a bit, changing the device_model_override value, disk and r= oot/extra options.

Has anyone successfully created= Xen guests on the cubietruck?
Care to share how you went about g= etting it to work?

Note: The unikernels work fine.=

Thanks in advance.

2- Com= piling the linux kernel seperately using gcc-4.9 on the CT, and changing th= e cfg file to use the zImage kernel instead I get the following error:
```

Currently, my cfg file looks like this:

root =3D "/dev/xvda1 ro"= ;
#extra =3D 'console=3Dhvc0 xencons=3Dtty root=3D/dev/xvda1&= #39;
```
But I've messed with it quite a bit,= changing the device_model_override value, disk and root/extra options.

Has anyone successfully created Xen guests on the cub= ietruck?

It does seem to be a configuration issue of some kind. At least the capture looks consistent with the console messages from the unikernel. I understand that the ping was done from your Mac to the unikernel? What I meant to ask is to see a working capture (e.g. ping Mac -> dom0, or capture Mac -> Ubuntu domU HTTP) in addition to the non-working one (Mac to unikernel). If you set your unikernel MAC address to the same as your working Ubuntu domU (while the Ubuntu domU is stopped of course), does it make any difference to the problem? Even if it doesn't help, it would be a more direct comparison between the good and bad captures. Perhaps attach the pcap files if it is not too much trouble?

Thanks for noticing, I've created https://github.com/mirage/mi= rage-seal/issues/4 to track that. Patches are welcome :-)

I see mirage-seal as a default way to publish static contents with mirage i= n the near future. I plan to add a mode to serve HTTP contents only (but ye= s, currently the goal is to test the other libraries).

Thanks for noticing, I've created https://github.com/mirage/mi= rage-seal/issues/4 to track that. Patches are welcome :-)

I see mirage-seal as a default way to publish static contents with mirage i= n the near future. I plan to add a mode to serve HTTP contents only (but ye= s, currently the goal is to test the other libraries).

(and revert the rest of domU_test to the original from the article, including the original kernel) I don't know much about how Xen memory allocation works but given that dom0 has 512 MB it might be too optimistic to expect 512 MB to be available to a guest. Of course if that fixes your problem then the article should be updated (it might have been tested on the Cubietruck when it was written).
