[bug#52555] [RFC PATCH 0/3] Decentralized substitute distribution with ERIS

[pukkamustard]

Hello Guix,

This is an initial patch and proposal towards decentralizing substitute
distribution with ERIS.

ERIS (Encoding for Robust Immutable Storage) [1] is an encoding of content into
uniformly sized, encryped and content-addressed blocks. The original content
can be reconstructed only with access to a read capability, which can be
encoded as an URN.

One key advantage of ERIS is that the encoding is protocol agnostic. Any
protocol that can transfer small (32KiB) sized blocks referenced by the hash of
their content will do. This can be done with things such as GNUNet, IPFS,
OpenDHT, HTTP or a USB stick on a bicycle.

The following patch allows substitutes to be published over IPFS using ERIS.
This is inspired and very similar to previous work on distributing substitutes
over IPFS [2].

The narinfos served by `guix publish` look like this:

For every compressed nar the ERIS URN is computed and added.

If the `--ipfs` is used for `guix publish` then the encoded blocks are also
uploaded to the IPFS daemon. The nar could then be retrieved from anywhere like
this:

--8<---------------cut here---------------start------------->8---
(use-modules (eris)
	     (eris blocks ipfs))

(eris-decode->bytevector
 "urn:erisx2:BIBC2LUTIQH43S2KRIAV7TBXNUUVPZTMV6KFA2M7AL5V6FNE77VNUDDVDAGJUEEAFATVO2QQT67SMOPTO3LGWCJFU7BZVCF5VXEQQW25BE"
 eris-blocks-ipfs-ref)
--8<---------------cut here---------------end--------------->8---

These patches do not yet retrieve content from IPFS (TODO). But in principle,
anybody connected to IPFS can get the nar with the ERIS URN. This could be used
to reduce load on substitute server as they would only need to publish the ERIS
URN directly - substitutes could be delivered much more peer-to-peer.

Other transports that I have been looking in to and am pretty sure will work
include: HTTP (with RFC 2169 [3]), GNUNet, OpenDHT. This is, imho, the
advantage of ERIS over IPFS directly or GNUNet directly. The encoding and
identifiers (URN) are abstracted away from specific transports (and also
applications). ERIS is almost exactly the same encoding as used in GNUNet
(ECRS).

Blocks can be stored in any kind of databases (see for example the GDBM
bindings [4]).

A tricky things is figuring out how to multiplex all these different
transports and storages...

The ERIS specification is still considered "experimental". However we feel
confident to stabilize it and intend to do so around February/March 2022 with a
release 1.0.0 of the specification. This will ensure that the identifiers
remain stable for the forseeable future (until the crypto breaks). Before that
there is also a small external security audit of the specification planned
(thanks to NGI0/NLnet!).

This is just a little demo of the idea and some food for thought and
discussion. Give it a try and let me know what you think!

I've also pushed the patches to my personal Guix mirror if you want to check it
out from there:

https://inqlab.net/git/guix.git/log/?h=wip-eris

Also CCing ~pukkamustard/eris@lists.sr.ht where there is some general ERIS
related discussion.

Thanks,

[bug#52555] [RFC PATCH 0/3] Decentralized substitute distribution with ERIS

Hi pukkamustard,

Woohoo, sounds exciting!

Yes, that’s nice.

Do we really need one URN per compression method?  Couldn’t we leave
compression (of individual chunks, possibly) as a “detail” handled by
the encoding or the transport layer?

Nice.  So adjusting ‘guix substitute’ should be relatively easy?

As a first step, ‘guix publish’ could implement RFC 2169, too.

I gather implementing the HTTP and IPFS backends in ‘guix substitute’
should be relatively easy, right?

Yes.  We don’t know yet what performance and data availability will be
like on IPFS, for instance, so it’s important for users to be able to
set priorities.  It’s also important to gracefully fall back to direct
HTTP downloads when fancier p2p methods fail, regardless of how they
fail.

Neat.

This is all very exciting.  I look forward to playing around with it!

I agree that it would be nice to leave this to the encoding layer as
that would allow certain optimizations (e.g. de-duplication).

Unfortunately, we haven't figured out yet what the most suitable
compression/format would be. Something like EROSFS seems good (as it
aligns data to fixed block sizes) [1]. But this seems a bit "clunky" for
just an archive format and there do not seem to be any libraries that we
could use to neatly integrate. It seems possible to block-align a Tar
archive, but that seems a bit hackey [2]. Other things to look into
might be Tarlz [3] and ZPAQ [4].

To get started I suggest just using one of the compressions/formats
already in Guix. zstd seems to be a reasonable choice (for the same
reasons why it makes sense to use zstd with `--discover` [5]).

Does that sound like a plan?

Yes, relatively! :)

I meant to send in a V2 that does this before going on holidays, but I'm
afraid I won't make it. V2 will come in early January!

Yes, those seem to be the two easiest backends to implement.

Yeah.  Though it may be that deduplication at the block level doesn’t
buy us much.  That was the conclusion I reached a long time ago[a], and
also seems to be supported by the recent guix-daemon deduplication
improvements[b].

[bug#52555] [RFC PATCH v2 0/5] Decentralized substitute distribution with ERIS

[pukkamustard]

Hello Guix,

Here comes the V2 of a proposal towards decentralizing substitute distribution
with ERIS.

A quick summary (as this has become quite long):

- This adds support for publishing and getting substitutes over IPFS.
- By using the ERIS encoding we are not limited to using IPFS as transport. We
  can also use GNUNet, Named Data Networking (possibly) or just plain old HTTP. Support
  for these can be added in (guix eris).
- These patches are still very rough and we need better logic for when to use
  IPFS et. al. and when to fallback to HTTP.
- There might be performance issues when using IPFS via the IPFS daemon HTTP
  API.

I found the setup for testing this a bit tricky. I will try and describe how I
have been testing it. Please let me know how this can be improved!

** Authorize local substitutes

We will be running a local substitute server so we need to add the local
signing key to the list of authorized keys. In the system configurations:

#+BEGIN_SRC scheme
  (modify-services %base-services
    (guix-service-type
     config =>
     (guix-configuration
      (inherit config)
      (authorized-keys
       (cons*
        ;; allow substitutes from ourselves for testing purposes
        (local-file "/etc/signing-key.pub")
        %default-authorized-guix-keys)))))
#+END_SRC

** Configure the local Guix checkout

#+BEGIN_SRC shell
./bootstrap && ./configure --localstatedir=/var --sysconfdir=/etc
#+END_SRC

The ~--sysconfdir~ is required so that guix will use the ACL in ~/etc/guix/acl~.

** Start the IPFS daemon

#+BEGIN_SRC shell
guix shell go-ipfs -- ipfs daemon
#+END_SRC

Start a local substitute server:

#+BEGIN_SRC shell
  sudo -E ./pre-inst-env guix publish --public-key=/etc/guix/signing-key.pub --private-key=/etc/guix/signing-key.sec --cache=/tmp/guix-publish-cache/ --port=8081 --compression=zstd:19
#+END_SRC

We use port 8081 as IPFS is running on 8080.

We use the temporary cache directory ~/tmp/guix-publish-cache~.

** Build some package locally

First we build some package:

#+BEGIN_SRC shell
./pre-inst-env guix build hello --no-substitutes --no-offload
#+END_SRC

#+RESULTS:
: /gnu/store/khaaib6s836bk5kbik239hlk6n6ianc4-hello-2.11

** Trigger the substitute server to "bake" a susbtitute

#+BEGIN_SRC shell

If you do this again after a few seconds you will get a different response that
has the ERIS URN and the FileSizes. The reason for this is that Guix publish
bakes the nars asyncrhonisly in the background:

These patches have added the ERIS and ERISFormat fields. Eventually we would
have figured out what the best format for use over ERIS is, for now we encode
it in the ERISFormat field.

** Removing a package from the store

This is necessary in order to make guix look for a substitute.

#+BEGIN_SRC shell
./pre-inst-env guix gc -D /gnu/store/khaaib6s836bk5kbik239hlk6n6ianc4-hello-2.11
#+END_SRC

#+BEGIN_SRC shell
sudo -E ./pre-inst-env guix-daemon --build-users-group=guixbuild  --debug  --substitute-urls=http://localhost:8081/
#+END_SRC

Note this will probably stop your system Guix daemon. Run ~sudo herd restart
guix-daemon~ to restart it.

We have just retreived the substitute for the hello package from IPFS. Hello
decentralized substitutes!

I have only tested this for fairly small packages (up to a few MB).

One issue with IPFS might be that we have to create a new HTTP connection to
the IPFS daemon for every single block (32KiB).  The IPFS daemon does not seem
to support HTTP connection re-use and neither does the Guile (web client).  I
fear this might become a performance issue. It seems possible to use IPFS more
directly by exposing the Go code as a C library and then using that with the
Guile FFI [1]. This is however a bit complicated and adds a lot of
dependencies. In particular, this should not become a dependency of Guix
itself. The performance of IPFS itself also needs to be evaluated, maybe the
IPFS HTTP API will not be the bottle-neck.

As mentioned in previous mail a simple HTTP transport for blocks would be a
good fallback. This would allow users to get missing blocks (things that
somehow got dropped from IPFS) directly from a substitute server. This is
different then getting the entire NAR from a substitute server. A user might be
missing a single 32KiB block and should be able to get only that. However, such
a HTTP fallback would also suffer from the one-connection-per-block issue. As
part of general ERIS research we are investigating CoAP as a better fallback
transport.

In any case, it would be necessary for the substitute server to store encoded
blocks of the NAR. For this I think it makes sense to use a small database. We
have bindings to use ERIS with GDBM [2]. It might also make sense to use
SQLite, especially if there are other use-cases for such a database.

I will be looking into the HTTP fallback and also using BitTorrent and GNUNet
as transports.

Thanks for making it so far and happy hacking!

There's an ipfs-service-type nowadays, so starting the daemon manually
isn't required (if using Guix System).

I have been writing a (Guile) Scheme port of GNUnet's client libraries
(https://git.gnunet.org/gnunet-scheme.git/).  Currently only NSE is
supported, but I'm working on DHT.  DHT search/put already works to a
degree (see examples/web.scm), but there are plenty of sharp edges
(see TODOs about disconnecting, reconnecting and stopping fibers,
and see guix.scm for Guile bugs that are patched out and extra guile-
fibers features).

Tests are being written a edge cases will be addressed.

Greetings,
Maxime.

Why are exceptions turned into #f (in (stat nar #f))?
Should this be done for all I/O errors, including, say, EOVERFLOW,
ENOMEM or ENAMETOOLONG, or only for ENOENT?

Is a race condition possible here?  If so, maybe consider doing
something like

  (catch 'system-error
    (lambda () (call-with-input-file ...))
    (lambda exception
      (and it-is-a-ENOENT
           (apply throw exception))))

to avoid it?

This should preferably only be catching exceptions indicating that
the daemon is down (exceptions indicating 404s, or system-errors
indicating network errors, ...).

This (ipfs-daemon-alive?) seems racy, although it's probably not.
Can we do

(define guix-eris-block-reducer
  (case-lambda
    (() (guard (c (oops-it-fails-because-the-daemon-cannot-be-
contacted? c)
                  #false)
          (eris-block-ipfs-reducer))
    [...]))

instead? (I don't think this will work as-is, because from the name and
thunkiness, it would appear that eris-block-ipfs-reducer returns a
procedure ...

guile-eris is an optional dependency, so this needs to be autoloaded.
Or guix/eris.scm must only be compiled when guile-eris is available.

IIUC (and quite probably I don't, because I've only being reading
things cursorly), eris-encode returns #false when the IPFS daemon is
down (because then guix-eris-block-reducer returns #false).

In that case, (uri->string eris-urn) = (uri->string #false) would
throw an exception:

scheme@(guile-user)> ((@ (web uri) uri->string) #false)
ice-9/boot-9.scm:1669:16: In procedure raise-exception:

'guix-eris-block-ref' just calls 'eris-blocks-ipfs-ref',
so I'm not seeing the point of this procedure.

guile-eris (which has the eris-read-capability? procedure) is an
optional dependency, so you have to check here is Guix was compiled
with guile-eris.

When Guix is compiled without guile-eris support, 
'(and eris? (narinfo-eris-urn narinfo))' is the worst, not the best.

Why is ERIS the best here?  Fast download speeds, decentralisation,
less network I/O, less heat production, more pronouncable than HTTPS?

Hi,

Is it possible for the following situation to happen?
If so, why not?

  1. server A is authentic
  2. server M is malicious, it tries to trick the client into
     installing an incorrect substitute
  3. (key of) server A is authorised
  4. (key of) server M is _not_ authorised
  5. server A and M are both in substitute-urls
  6. server A only serves ‘classical’ substitutes, server B also serves
     via ERIS+ipfs
  7. Both A and M set the same FileHash, References, etc. in the
     narinfo
  8. However, M set an ERIS URN pointing to a backdoored substitute.
  9. The client trusts A, and A and B have the same FileHash etc.,
     so the client considers the narinfo of B to be authentic
     because it has the same FileHash.
 10. The client prefers ERIS above HTTP(S), so it downloads via M.
 11. The client now installed a backdoored substitute!

Greetings,
Maxime.

According to <https://github.com/ipfs/go-ipfs/issues/3767>, the IPFS
daemon supports connection reuse according to some people and doesn't
according to other people.

Guix supports connection reuse, see 'call-with-cached-connection'
in (guix scripts substitute).

> I fear this might become a performance issue.

IIUC, the performance problem primarily lies in the round-tripping
between the client and the server.  If the client and the server are on
the same machine, then this round trip time is presumably small
compared to, say, localhost contacting ci.guix.gnu.org.

Still, connection reuse would be nice.

Security-wise, libipfs doesn't seem great: libipfs starts the IPFS
daemon inside the process and guix/scripts/substitute.scm is run
as root.

Seems a good idea to me -- DHTs can be unreliable.  I presume this will
be implemented with some kind of timeout: if no block is received
within N seconds, fallback to HTTP?

Also, don't forget to insert this missing block back into
IPFS/GNUnet/BitTorrent/..., otherwise less and less blocks will be
available until nothing is available anymore.

Wouldn't this be a huge database?  IIRC, according to logs.guix.gnu.org
the size of the nars of the substitute servers are somewhere in the
200G-2T range or something like that.

To reduce the size of the database, perhaps you could let the database
be a mapping from block ids to the name of the nar + the position in
the nar, and encode the block on-demand?

The database doesn't seem necessary, the substitute server could have
some end-point

  /publish-this-nar-again-into-IPFS/name-of-the-nar

which, when contacted, inserts the nar again into IPFS.  Then when a
block was unavailable, the client contacts this end-point and retries.

Maxime.

Good point. Starting the daemon manually is only necessary if you don't

Very interesting! I have been following your work on that a bit.

From what I understand gnunet-scheme interacts with the GNUNet services
and sends messages to the various GNUNet services. Is that correct?

Have you considered implementing the GNUNet protocols themeselves in
Guile? I.e. instead of connecting with the GNUNet services and sending
messages, implement R5N completely in Guile. IMHO this would be very
nice as one could use GNUNet protocols completely in Guile and not rely
on the GNUNet C code.

I believe this is somewhat the direction being taken with the GNUNet Go
implementation (https://github.com/bfix/gnunet-go) and also in line with
recent efforts to specify the individual GNUNet components and protocols
more independantly of one another (e.g. R5N is specified to work over IP
- https://lsd.gnunet.org/lsd0004/).

Yes, currently it is an unnecessary level of abstraction.

The idea is that when there are multiple backends/transports they are
multiplexed here. E.g. guix-eris-block-ref would attempt to use
HTTP/IPFS or whatever to get the block. Whatever calls
guix-eris-block-ref does not need to know from where the blocks come.

I hope to make this more clear in a V3 that will add HTTP transport.

A valid question. But (stat nar #f) is not something I introduced. It is
already in guix/scripts/publish.scm like that.

To me turning all exceptions to #f makes sense. Here we only want to
know if the file is readable. As the NAR is baked in the background by
another thread the case where the compressed NAR does exist yet will
happen. In that case we don't worry, we just don't publish the
`FileSize` and `ERIS` fields in the narinfo.

No, eris-encode will still return the ERIS URN. The blocks will just not
be stored in IPFS if the IPFS daemon is not running. See also my

Yes, I guess it could be checked a bit finer. But at the end if an
exception happens then the IPFS daemon is probably not reachable, right?
If we don't care about the reason why it is not reachable then why
bother with catching finer grained exceptions?

Yes, eris-block-ipfs-reducer returns and SRFI-171 reducer. This is a
3-arity procedure that is either initialized, called with a block to
reduce and finalized.

The #f that the initialization case returns (0-arity call) is the state
of the reducer. In the block reducing case (2-ary call) the state (the
ipfs variable) is checked if ipfs is alive. If not the blocks are just
forgotten.

So guix-eris-block-reducer always returns a SRF-171 reducer, regardless
of if IPFS is alive or not. This is important as the ERIS URN can still
be computed without the IPFS daemon running.

Those are all possible reasons. I think we first need to do some
experiments to see if any of those claims can be justified.

In general, the logic for when to use ERIS transports needs more
thought.

For one, I think it should be user configurable. I can imagine that
certain users do not want to use decentralized substitutes at all. Users
should be able to deactivate the entire ERIS thing.

For the default, I personally think it would be ok to try and use
ERIS. The only thing we absolutely need is a clean fallback logic that
transparently falls back to getting the entire NAR by HTTP. Currently
such a fallback is not yet implemented.

Hm, from what I understand connection re-use is something introduced in
HTTP/2 and go-ipfs does not do HTTP/2
(https://github.com/ipfs/go-ipfs/issues/5974).

Remains to be seen if this is a problem.

It is considerably more pronounced than with regular usage of IPFS as we
make a HTTP request to IPFS for every 32KiB block instead of for an
entire file (what most people do when using the IPFS daemon).

This might be a bit of a burden for users. As you mention the size of
such a database might become considerable.

Yes! I've also been thinking of this - a "in-file" block store. I think
this makes a lot of sense for Guix but also other things (e.g. sharing
your music collection).

Another problem with IPFS/GNUNet is that they have their own storage. So
even if are clever about storing blocks in Guix, IPFS and GNUNet will
have their own copy of the blocks on disk. I think it would be much
nicer if DHTs/transport layers don't do block storage but are provided
with a callback from where they can get stored blocks. I believe this is
what OpenDHT does
(https://github.com/savoirfairelinux/opendht/wiki/API-Overview).

I think we should propose such a change to the GNUNet R5N specification
(https://lsd.gnunet.org/lsd0004/).

But for a HTTP block endpoint we would still need such a database/block
storage.

I think it is important that we do not rely on IPFS for block
storage. The decentralized block distribution should work even if the
IPFS daemon is not available.

Yes, it works like the C GNUnet client libraries, except it's in Guile
Scheme and a few different design decisions were made, e.g. w.r.t.
concurrency.

I didn't, at least not _yet_.  As-is, things are already complicated
enough and the client code seems a lot simpler than the service code.
Though perhaps in the future ...

E.g., for testing the DHT service, the test code effectively creates a
tiny, limited, in-memory DHT service (not communicating to any peers)
that's buggy in some respects (not yet committed, but will be in
tests/distributed-hash-table.scm).

> IMHO this would be very nice as one could use GNUNet protocols completely
> in Guile and not rely on the GNUNet C code.

While it's not a priority, I'm not opposed to someday implementing the
services in Guile and testing whether they can communicate with C
peers.

However, keep in mind that GNUnet is supposed to be able to eventually
replace the TCP/IP stack, and running the DHT, NSE, NAT, FS, CADET,
TRANSPORT ... services in every web browser, in every mail client, in
all "guix substitute" and "guix perform-download" processes, etc. is
rather wasteful (memory-wise and CPU-wise), so I'd prefer this not to
be the _default_ option.

(I'm not sure if you were referring to that.)

Greetings,
Maxme.

No this should not work.

The ERIS URN is only used if the entire narinfo is signed with a
authorized signature. The FileHash is not used when getting substitutes
via ERIS (being able to decode ERIS content implies integrity).

The interesting case that would be allowed with ERIS is following:

1. Server A is authentic and its key is authorized.
2. Servers M1 to MN are potentially malicious and their keys are not
   authorized.
3. Server A and servers M1 to MN are in the substitute-urls.
4. Client gets Narinfo from server A and uses the ERIS URN from there.
5. Client can get blocks simultaneously from Server A and servers M1 to
   MN.
6. Client decodes content with the ERIS URN and can be sure that they
   have the valid substitute.

So client only needs to trust A but can use M1-MN (simultaneously) for
fetching the content.

Do we need a database at all?

E.g., if the client cannot download the data in the range [start, end]
because the corresponding block has disappeared, can it not simply
download that range from https://ci.guix.gnu.org/nar/[...]
(not sure about the URI) using a HTTP range request?

(Afterwards, the client should insert the block(s) back into
IPFS/GNUnet/whatever, maybe using this proposed ‘in-file block store’
such that other clients (using the same DHT mechanism) can benefit.)

Maxime.

This does not work as the mapping from block reference to location in
NAR can not be known by the client who only holds the ERIS
URN. Furthermore, some blocks will be intermediary nodes - they hold
references to content blocks (or other intermediary nodes) but not
content itself.

It might make sense for some clients to make content available to other
clients and to go trough the extra effort of putting blocks back into
IPFS/GNUNet/whatever. But this should be optional. Maybe we can call
such clients "caching peers"?

IMO A client should by default only deal with things that are strictly
necessary for getting substitutes. The substistute servers (and caching
peers) should make sure substitutes are available to clients, whether
over IPFS/GNUNet/whatever or plain old HTTP.

If re-inserting missing blocks back into the IPFS/GNUnet/whatever is
made optional and is off by default, then almost nobody will enable the
‘caching peer’ option and we will have freeloaders, somewhat defeating
the point of GNUnet/whatever.

In a classic setting (‘plain old HTTP’), serving and downloading is a
separate thing.  But in a P2P setting, downloading cannot be separated
from uploading -- strictly speaking, a peer might be able to download
without uploading (depending on the P2P system), but that's anti-
social, not something that should be done by default.

However, if re-inserting missing blocks is _on_ by default, then there
doesn't seem to be any trouble.

Greetings,
Maxime.

The client not only knows the ERIS URN, it also knows the location of
the nar (over classical HTTP) because it's in the narinfo.

> Furthermore, some blocks will be intermediary nodes - they hold

> content itself.

If an intermediary node (responsible for, say, bytes 900--10000)
is missing, then the bytes 900--10000 could be downloaded via HTTP.
Whether the node is close to the top, or close to the bottom, in ERIS'
variant of Merkle trees, doesn't matter much.

Granted, if the nar is, say, 1 GiB, and the top-level block is missing,
then we'll have to download 1 GiB over HTTP, even if most lower blocks
exist on IPFS/GNUnet/whatever, which isn't really great.

We could also do some combination of the GDBM database and HTTP
Content-Range requests: most nodes are leaf nodes (*).  Instead of
representing all nodes in the database, we could include only
(intermediate) nodes responsible for data of size, say, 4MiB.

(*) At least, that's the case for binary trees, presumably something
similar holds for ERIS.

I don't know the specifics for ERIS, but for (balanced) binary trees,
not storing the leaf nodes would save about 50% (**), which is a rather
nice space saving.

(**) This assumes the ‘block size’ is the size for storing two pointers
to the children, but in practice the block size would be quite a bit
larger, so there would be more space savings?

Perhaps we are overthinking things and the GDBM (***) database isn't
overly large, or perhaps missing blocks are sufficiently rare such that
we could simply download the _entire_ nar from classical HTTP in case
of missing blocks ...

(***) Guix uses SQlite databases, so I would use SQLite instead of GDBM
unless there's a compelling reason to use GDBM instead.

Maxime.

The exception could be caused by, say:

  * an unbound variable
  * wrong arity
  * type error
  * stack overflow
  * prompt tag does not exist in current environment
  * out of memory

Except for the last one, these causes are all bugs and hence shouldn't
be surpressed.  Granted, this is a bit unlikely since this use of
'http-post' is very simple, but it's far from impossible for
(web client) to have a bug.

Perhaps I'm missing something here, but in that case, shouldn't "ERIS"
be added to %mandatory-fields in (guix narinfo)?

Anyway, I don't see what prevents an unauthorised narinfo with a ERIS
URN to be used: the narinfo is chosen with

  (define narinfo
    (lookup-narinfo cache-urls store-item
                    (if (%allow-unauthenticated-substitutes?)
                        (const #t)
                        (cut valid-narinfo? <> acl))))

where lookup-narinfo is a tiny wrapper around lookup-narinfos/diverse.
lookup-narinfos/diverse considers both unauthorised and authorised
narinfos, and can choose an unauthorised narinfo if it's ‘equivalent’
to an authorised narinfo (using equivalent-narinfo?)

equivalent-narinfo? only looks at the hash, path, references and size,
and ignores the ERIS.  As such, an unauthorised narinfo with a
malicious ERIS URN could be selected.

However, it turns out that all this doesn't really matter: whether the
port returned by 'fetch' in (guix scripts substitute) came from
file://, http://, https:// or ERIS, the file hash is verified later
anyway:

                  ;; Compute the actual nar hash as we read it.
                  ((algorithm expected)
                   (narinfo-hash-algorithm+value narinfo))
                  ((hashed get-hash)
                   (open-hash-input-port algorithm input)))

      [...]

      ;; Check whether we got the data announced in NARINFO.
      (let ((actual (get-hash)))
        (if (bytevector=? actual expected)
            [...]

False alarm I guess!

Maxime.

You're right. I was not aware that parts of unauthorized narinfos are
used when they are deemed equavelent to authorized narinfos with
equivalent-narinfo?.

Yeah, good that the hash is checked. Still, I think we should not even
try downloading a ERIS URN that is not authorized.

I think adding a check to equivalent-narinfo? that makes sure that the
ERIS URNs are equivalent if present would fix this. wdyt?

At least in GNUnet, there are quota on the size of the datastore
(and presumably, whatever the DHT service uses as database).  When it's
exceeded, old blocks are removed.  So I don't see a burden here,
assuming that the quota aren't overly large by default.

[bug#52555] [PATCH v3 0/8] Decentralized substitute distribution with ERIS

[pukkamustard]

Hello Guix,

I'm very happy to present a V3 of a proposal towards decentralizing substitute
distribution with ERIS. An initial version [1] and a V2 [2] are now almost a
years old!

The idea is to use ERIS (Encoding for Robust Immutable Storage) [3] to allow
more decentralized substitute distribution. ERIS defines an encoding of
content into uniformly sized, encrypted and content-addressed blocks
(32KiB). The content can be decoded from the blocks given a short identifier
called the read capability. It allows a network-optimized form of
content-addressing.

Blocks can be transported over many different transport protocols, such as
HTTP, CoAP, GNUnet, IPFS or a SD card sent via pigeons. Only the read
capability must be transmited securely. Given an authentic read capability,
the content can be decoded correctly from blocks that might have been
transported over unreliable (and untrusted) protocols.

For Guix, substitutes (Nar files) are encoded using ERIS and the read
capability is added to the signed Narinfos. The read capability published in
the Narinfo can then be used to decode the Nar from blocks that are fetched
from many peers over many different protocols.

This version of the patches allows blocks to be fetched over HTTP and IPFS.

A summary of this patch series:

- Use the stable version of the ERIS encoding (version 1.0.0)
- Add two fields to Narinfos (ERIS and ERISFormat)
- Store blocks of published substitutes in a local block store (in
  `/var/guix/eris`)
- Add an endpoint for resolving ERIS blocks over HTTP (a la RFC 2169)
- Use ERIS when fetching substitutes
- Use IPFS for de-referencing ERIS blocks

Testing procedure is a bit tedious, but described in the V2:
https://issues.guix.gnu.org/52555#8-lineno16

Please give it a try or a read.

Two commits are marked as WIP and have some todos regarding
configuration. Suggestions in how to go about Guix wide configuration are very
welcome.

Some further ideas include:

- We've been researching CoAP (RFC 7252) as a transport protocol for
  blocks. It is lightweight, performant, well-specified and optimized for
  small implementations, meaning it can be reasonably implemented in pure
  Guile. This would allow more light-weight peer connections (over UDP) and
  also discovery of local peers via CoAP service discovery [4] - very similar
  to how Avahi is currently used.
- Publish substitutes to IPFS. Currently substitutes are not published to
  IPFS. It might make sense to add a CLI command that does this. In a previous
  verion of the series this was done when a substitute is requested over
  HTTP. But it seems to make sense to publish on IPFS (or other protocols)
  independantly of the HTTP endpoints.
- Use an optimized format for encoding Nars. Based on some investigation into
  SquashFS, EROFS and de-duplication of files in substitutes [5], we have an
  initial proposal of how to encode Nars (and in general file system trees) in
  ERIS so that common files are de-duplicated:
  https://codeberg.org/eris/eer/pulls/2.
- More transport protocols.

Thanks for making it so far! :) I'd be very happy for your thoughs and
ideas. There might also be opportunity to discuss these ideas at Guix Days in
February.

Best regards and a happy new year,
pukkamustard

[bug#52555] [PATCH v3 6/8] WIP: eris: Use HTTP to get ERIS blocks.

[pukkamustard]

- guix/eris.scm (guix-eris-block-ref): Refactor from call-with-eris-block-ref
and use eris-http-block-ref.
- guix/eris/fs-store.scm (eris-fs-store-ref): Refactor to take keyword
arguments.
- guix/scripts/substitute.scm (download-nar): Use guix-eris-block-ref.
- guix/scripts/publish.scm (make-request-handler): Use refactored
eris-fs-store-ref.

TODO:

- default value for %eris-peers parameter in (eris)

Neat!  (Do we have an implementation yet for SD-cards-over-pigeons?)

Nice.

> - Store blocks of published substitutes in a local block store (in

OK.  There are still I guess a number of unknowns, including the cost of
ERIS support for publishers (how much disk space ‘guix publish’ will use
for blocks, how much CPU is needed to compute those blocks, bandwidth
usage over IFPS/HTTP) and for consumers (performance of substitution
over HTTP+ERIS or IPFS+ERIS CPU-wise and bandwidth-wise).

To address that, we’ll need to make it easy to test, and to make it easy
to disable it if things don’t work as expected.

(Perhaps this is already the case, I’m thinking out loud.)

Definitely!  I think it would be great if you could present what you’re
up to and maybe make a quick demo.

Thanks for the great news to begin the year!

I think you remove the ‘let’ and just call ‘eris-encode’ in tail
position (Guile truncates multiple-value returns.)

Where is ‘eris-encode’ storing the blocks?  I don’t see any parameter
here.

I guess it should go to /var/cache/guix/publish/eris or similar.

Would be nice to make ERIS encoding optional, with a command-line
switch to turn it on.

Maybe this should be private to (guix scripts publish)?

Also, the store directory should be /var/cache/guix/publish/eris by

Could you add docstrings, remove tabs, and use (ice-9 match) instead of
car/cdr?  :-)

Whole files (blocks, right?) get loaded in memory.  Is that OK or should
it be avoided?

There are time-of-check-to-time-of-use race conditions with those
‘file-exists?’ calls.  In the case of ‘ref’, you can instead write:

  (catch 'system-error
    (lambda ()
      (call-with-input-file …))
    (lambda args
      (if (= ENOENT (system-error-errno args))
          #f
          (apply throw args))))

In the case of ‘reducer’, perhaps it’d be safer to write the block
atomically with ‘with-atomic-file-output’?  (And remove the
‘file-exists?’ check too?)

Write “file” rather than “path” (the latter is used to refer to “search
paths”).  :-)

[bug#52555] [PATCH v4 0/7] Decentralized substitute distribution with ERIS

[pukkamustard]

Dear Guix,

This is the V4 of a proposal towards decentralized subsitute distirbution
using the ERIS encoding. The initial proposal was submitted in December 2021,
V2 and V3 a year later in 2022. All is still very much work-in-progress, but
I'm happy to submit it as is to keep up with good old traditions.

Thank you also for all the valuable comments and feedback via mail and live at
Guix Days last year. Sorry for being so slow to react.

The general idea of the proposal is to use ERIS (http://purl.org/eris) for
substitute distribution. This allows substitutes to be shared over various
protocols such as IPFS, GNUnet, NNCP, HTTP, CoAP, a USB stick or some
Spritely-esque fun.

ERIS itself defines an encoding of content into uniformly sized, encrypted and
content-addressed blocks. The original content can be decoded with a short
read capability that can be encoded as an URN and access to the blocks that
make up the content. Blocks can be shared over different protocols with low
security requirements on the transport layer itself. Read capabilities need to
be shared in a secure manner.

This series does following:

- Adds an `ERIS` field holding the ERIS read capability of a substitute to the
  Narinfo as published by `guix publish`
- Allows the daemon/substitute script to decode content using the ERIS URN
  instead of fetching a substitute via HTTP.
  
## Changes to previous version

### Fibers

When encoding and decoding it is important for performance to be able to fetch
multiple blocks concurrently (from potentially multiple peers). For this we
use Guile fibers.

Fiberization is currently very crude as there seem to be weird interactions
with the parallization strategies currently used by `guix publish` and `guix
substitute`. Help here is extremely welcome.

### ERIS-FS

In previous versions we encoded the Nar-file of the susbstitute. In this
version we use a specialized encoding of file-system trees for ERIS: ERIS-FS
(https://eris.codeberg.page/eer/eris-fs.xml).

ERIS-FS allows de-duplication of files and much easier parlallized decoding of
substitutes. The ideas are similar to the custom encoding defined for
substitutes over IPFS (https://issues.guix.gnu.org/33899).

One major consequence is that the SHA256 sum of the Nar file as published in
the Narinfo is no longer used to verify integrity of downloaded
susbtitute. Instead we must ensure that the `ERIS` field in the Narinfo is
trusted, `equivalent-narinfo?` and such have been changed towards this. Thanks
to Maxime for pointing out this subtlety!

### External Block Store Daemon

Ludovic Courtès <ludo@gnu.org> writes:

> Also, the store directory should be /var/cache/guix/publish/eris by
> default IMO.

This comment caused a lot of pondering and hacking! :)

The problem seems to be that two processes need to be able to access the block
store securely: `guix publish` when publishing substitutes and the Guix daemon
when fetching substitutes (blocks need to be stored when fetching for
de-duplication). `guix publish` is usually run as a non-privileged user,
whereas the Guix daemon runs with much higher privileges. The block store
needs to be secure in the sense that manipulating blocks should be prevented
by less privileged processes.

I'm afraid the only solution I came up with is that the block store is not a
Unix directory or database, but a daemon that listens on a Unix Socket.

Enter Kapla (https://codeberg.org/eris/kapla). Kapla is a Guile program that
stores and transports blocks. The Guix daemon (via substitute scripts) and the
`guix publish` server talk to Kapla over a Unix socket. Kapla stores blocks in
a database (SQlite) and connects with multiple peers and/or services such as
IPFS/GNUnet to get blocks.

I was fighting such an architecture for a long time. I would have preferred if
the Guix daemon and `guix publish` simply use a library for everything instead
of relying on another external service. However, there seem to be some advantages:

- Managing peers seem to be quite complex and stateful. Maybe better if this
  is externalized from Guix proper.
- The block storage and transport mechanisms can be used to share any files
  (try `kapla encode my-file` and `kapla decode ...`).
- We can experiment with more transports quicker in a service external to Guix
  and include dependencies that might not make sense to have in Guix proper.
  
The protocol that is used to talk to the external block store is CoAP over
Unix Sockets or TCP. Kapla is not the only software that speaks this
protocol. There is also a Golang block store that can be used
(https://codeberg.org/eris/eris-go).

### CoAP for block transport

Currently the protocol over which blocks are transported over networks is the
Constrained Application Protocol (CoAP)
(https://eris.codeberg.page/eer/coap.xml). CoAP is well suited as it allows
multiple asynchronous in-flight requests (unlike HTTP 1.1). This is important
for parallizing block retrieval. It also allows bi-directional requests,
making it attractive for more peer-to-peer systems where some peers might not
have a public IP.

As it is designed for constrained environment it is quite simple and the
implementation we use is in pure Guile.

More block transports can be added by implementing them in Kapla (e.g. IPFS or
GNUnet) or using something completely different than Kapla that speaks CoAP
over Unix Sockets (such as eris-go that also can use NNCP for block
transport).

### Comments to V3

I hope to have addressed all comments to the V3 (Thanks Ludo!). This included
things like organizing commits differently, using (ice-9 match) and how to
handle multiple return values.

## Testing

Testing is a bit complicated. We need to find a better and more systematic way
of doing so. Suggestions are very welcome!

Manually this is how to do it:

1. Authorize local substitutes

We will be running a local substitute server so we need to add the local
signing key to the list of authorized keys. In the system configurations:

```
  (modify-services %base-services
    (guix-service-type
     config =>
     (guix-configuration
      (inherit config)
      (authorized-keys
       (cons*
        ;; allow substitutes from ourselves for testing purposes
        (local-file "/etc/signing-key.pub")
        %default-authorized-guix-keys)))))
```

2. Configure the local Guix checkout

#+BEGIN_SRC shell
./bootstrap && ./configure --localstatedir=/var --sysconfdir=/etc && make
#+END_SRC

The ~--sysconfdir~ is required so that guix will use the ACL in ~/etc/guix/acl~.

3. Start a Kapla daemon:

```
./pre-inst-env guix build kapla -- kaplad -d
```

The `-d` option enables debug output. Kapla will listen for connection on a
Unix socket. The path will be output, e.g.:

```
2023-12-23 15:10:23 (INFO): Listening on Unix socket /run/user/1000/eris.sock
```

3. Build some package that we will 

```
$ ./pre-inst-env guix build libchop --no-grafts
/gnu/store/60m6qih391rq95ck64am8ir64z0sv0zr-libchop-0.5.2
```

4. Start a local publish server

```
sudo -E ./pre-inst-env guix publish --public-key=/etc/guix/signing-key.pub --private-key=/etc/guix/signing-key.sec --cache=/tmp/guix-publish-cache/ --eris=coap+unix:///run/user/1000/eris.sock
```

I need to run it with sudo in order to be able to use the proper signing keys.

The `--eris=STORE_URL` option defines where to store blocks. `--eris` can also
be provided without a URL which will cause the ERIS read capability to be
computed but blocks won't be stored anywhere. See "Proposed Deployment" on
when this might make sense.

5. Get the narinfo from the publish server

```
$ curl http://localhost:8080/60m6qih391rq95ck64am8ir64z0sv0zr.narinfo

```

Note the new `ERIS` field. You might have to get the narinfo twice for all the
fields to appear.

The ERIS read capability URN (urn:eris:BIARSURIJ...) contains enough
information to decode the substitute. If you look at the kaplad log output you
will see that some blocks were stored. You could now run:

```
kapla decode urn:eris:BIARSURIJ3WYLEINE6W5ZF7LKTIHL42AE367TQ355ORW5UZVSTQGT5H5T2OLKF7XICML3VHLTLMDWXLUCQVKHRKNVREV3GMVX3J5RMT4GU out
```

to decode the substitute to the folder out. The Guix daemon can do the same
when getting substitutes.

6. Remove the libchop store item:

```
guix gc -D /gnu/store/60m6qih391rq95ck64am8ir64z0sv0zr-libchop-0.5.2
```

7. Start the guix daemon from the checkout:


```
sudo -E ./pre-inst-env guix-daemon --build-users-group=guixbuild --eris-store-url=coap+unix:///run/user/1001/eris.sock --substitute-urls=http://localhost:8080/
```

Note that the `--eris-store-url` argument points to the same store as what we
used for the publish server - the blocks come go to and come from the same
place. 

We need to use the local publish server for getting the narinfo with the
`ERIS` field.

8. Get the substitute:

```
./pre-inst-env guix build libchop --no-grafts
substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'.substitute: updating substitutes from 'http://localhost:8080/'... 100.0%

/gnu/store/60m6qih391rq95ck64am8ir64z0sv0zr-libchop-0.5.2
```

Substitute was fetched using ERIS!

The daemon automatically tries to use ERIS when the `--eris-store-url` is
passed and the narinfo has a signed ERIS field. If not it will fetch
substitutes using HTTP. On failures while using ERIS it will also revert back
to getting substitutes via HTTP.

9. Restart your system guix daemon

```
sudo herd restart guix-daemon
```

10. Figure out a better way to test this.

## Proposed Deployment

As an initial deployment it would be nice if the official Guix substitute
servers include the ERIS read capability in the Narinfo withouth making blocks
available. This only requires a bit of CPU for computing the ERIS read
capability. No additional disk space or bandwidth is required by the official
substitute servers.

Users can get the signed ERIS read capability from the official Guix
susbtitute servers but can fetch blocks from anywhere while still being sure
to get the right substitutes.

This would allow community members to make blocks available independently and
experiment with various transports while not changing the trust-model when
fetching substitutes.

## TODOs

- [ ] Better fiberization of `guix publish` and `guix/scripts/substitute.scm`
- [ ] Debug issue where blocks of large substitutes are not properly stored
      (possibly related to hackey fiberization).
- [ ] Add Guix tests
- [ ] Add documentation.
- [ ] Write a RFC along the proposed Request-For-Comment process
      (https://issues.guix.gnu.org/66844)
- [ ] Allow encoding of blocks without running `guix publish` (maybe an `eris`
      format for `guix pack`).
- [ ] Dependencies (guile-eris and guile-coap) contain some fixes that need to
      be properly released.
- [ ] Implement CoAP peer connections and maybe IPFS transport in Kapla.
- [ ] Release initial version of Kapla.
- [ ] Update service definitions for `guix-publish`, `guix-daemon` with an
      option to enable decentralized substitute stuff and add service
      definition for `kapla`.

## Hic Sunt Dracones

Everything is still quite fragile. The fiberization of `guix substitute` and
`guix publish` is hackey. Kapla is still very limited and unreleased. But I
hope to have been able to capture the current state of things and paint a
picture of the plan.

Thanks for making it so far and for your comments, questions and hackings.

Greetings,
pukkamustard
