(Unofficial) wireguard packages for Debian Stretch (testing)

(Unofficial) wireguard packages for Debian Stretch (testing)

[-- Attachment #1: Type: text/plain, Size: 953 bytes --]

Mellow greetings,

In case it's of use to anyone, I've built wireguard packages for Debian
testing. I wanted to play with wireguard on my Debian Stretch systems, but
wireguard is currently locked to Sid only until 1.0 brings API stability
guarantees.

So, I set up a cronjob that rebuilds the Sid source package on a Stretch
system, and the result is wireguard packages that track the latest release,
but don't pull in unstable versions of libc and whatnot when you try to
install them, as would happen if you tried to install via package pinning.

Naturally, you have only my word that the packages are unmodified rebuilds
of Debian's original package, and you're trusting packagecloud to not
tamper with the packages (it's their signing keys, not mine) so caveat
emptor. It works for me, it might work for you as well.

With the warnings and disclaimers out of the way, here's the repo:
https://packagecloud.io/danderson/wireguard?filter=debs

Mellow yellow,

That's a great idea. Do you intend to track dkg's sid package more or
less faithfully? If so, I'd be happy to advertise this on the
wireguard.io/install/ page, since I'm sure a lot of people (including
myself!) would benefit immensely from that.

Could you send some bulletproof instructions -- 3 or 4 lines of
commands like what's there currently -- and I'll put it on the site?

Thanks,
Jason

In that package repository, I intend to track the sid package exactly. If I
ever take up hacking on wireguard, I'll use a separate repository for any
modified versions.

If so, I'd be happy to advertise this on the

Cool! I'll see about setting up debian stable as well.

The instructions you have on there now are fine if you're okay with
packagecloud's shell script. Manual instructions that work are:

sudo apt-get install -y apt-transport-https linux-headers-amd64 curl
curl -L https://packagecloud.io/danderson/wireguard/gpgkey | sudo apt-key
add -
echo "deb https://packagecloud.io/danderson/wireguard/debian/ stretch main"
| sudo tee /etc/apt/sources.list.d/wireguard.list
sudo apt-get update
sudo apt-get install -y wireguard-dkms wireguard-tools

Note that right now, only amd64 packages are available. If you think
there's demand for Debian on 32-bit x86, I can set up i386 builders as well.

Hi Dave,

Good idea. I don't like the scary pipe to bash one liners. I'll go
with what you suggested. However, is `linux-headers-amd64` really
required?

Thanks,
Jason

Hi,

Yes, linux-headers-amd64 is required, otherwise the wireguard-dkms package
won't build the kernel module, and leave a very confused user. I *think* I
saw a conversation in this list's archives about whether the headers should
be made a dependency of wireguard-dkms, but I can't find it now...

Okay, I've set up a Debian stable builder as well... However, Debian stable
has a 3.16 kernel, and wireguard-dkms requires >=3.18, so installation
fails. Assuming 3.18 is a hard lower-bound on kernel versions, it looks
like jessie will never run in-kernel wireguard. Fortunately it'll be moot
in a few months when stretch becomes the new stable.

I doubt anybody cares about i386, but likely armv{6,7} and arm64 are
in demand somewhat, at the very least due to Rasberrian users.

I probably could backport to 3.16... It's a bit of a PITA but still
possible if there's sufficient demand. I'll wait to see if people pipe
up.

Jessie-backports has linux 4.9, so it's probably much simpler to require
users to install this.

Hmm, I don't have functional arm-ish things on hand, but I'll see what I
can do with emulated setups. I'll skip i386 for now, if it turns out to be
in demand it's one VM spinup away.

Oh, excellent! I'll leave the jessie builder running then.

Jason: I'll get back to you once I've looked into setting up builds for
arm, to see how to revise the instructions. Given that each distro version
is likely to be slightly different, perhaps it'd be better to just link to
a readme on packagecloud.io, to avoid cluttering the install instructions
on wireguard.io?

I'm failing at setting up arm builds, raspbian/rpi emulation is not in a
great shape these days. In the meantime, debian stable for amd64 is up.
Updated instructions for both debian versions are at
https://packagecloud.io/danderson/wireguard#readme-scrollto . In
particular, the jessie install requires first installing a backported
kernel. I'll keep poking at arm builds for a bit, but I don't promise
anything.

Good idea. I'll link to that instead.

I appreciate your interest in getting wider distribution for wireguard,
David, but i'm not convinced this approach makes much sense.

It seems like a lot of extra work compared to just putting wireguard
into stretch-backports once stretch is released.

Until stretch releases, people running testing should be able to just
add the unstable repository and pin it to be lower priority than testing
(see apt_preferences(5)).

Using this standard approach, users won't need to:

 a) add a new key to their apt configuration, which increases the attack
    surface for all installed packages (btw, the proposed shell pipe
    into "apt-key add -" is deprecated, see for example commentary at
    https://bugs.debian.org/853858)
 
 b) be dependent on some alternate suite of build daemons -- if debian
    supports your build environment, the buildds will have the wireguard
    packages.

So I don't see much to recommend the proposed approach by comparison,
and i don't think that it should be documented as a recommended approach
upstream, unless there are clearer benefits that i'm missing here.  In
that case, i'd like to know what those benefits are :)

Hey Daniel,

That makes sense to me. I don't know much about Debian best practices,
so I'll defer to your judgement and revert the /install/ page
instruction. If David manages to convince you otherwise, I'll re-add
it then.

"Once stretch is released" could be a few months still, right? It's only
just gone into final freeze. I agree that once it's released, backports is
definitely the right way to distribute.

So, I'd initially tried doing this, by adding the unstable repository at a
negative priority. What turned me off is that even with that low
preference, attempting to install the wireguard packages seemed to pull in
some core system libraries (libc and such) from unstable as well. And while
I'm excited about wireguard, I'm not "install unstable base libraries"
excited :).

That said, it's quite possible I was just not using the preference system
correctly. If it's possible to express "Install *only* wireguard-* from
unstable, never anything else", then I agree, that's definitely the way to
go.

Fair enough, I defer to your greater experience with Debian packaging.
Fortunately, packagecloud's stats say that there were no installs from my
repository, so assuming I can get pinning to work properly, the only
systems that need cleanup are my own.

Yep, it could still be a few months, depending on how rapidly we're able
to fix the remaining outstanding release-critical bugs.

absolutely!  However, i'm a little surprised that this happened.  If you
could show a transcript of what you did specifically, and what the
resultant proposed apt changes were, i'd be interested in understanding
what went on there.

on a similar system i'm using (stretch, with unstable available but
pinned low), i see only packages from stretch being installed (aside
from wireguard itself, clearly)

Thanks for the hint, it worked fine on my stretch system!  Here are the
packages that got pulled:

The following NEW packages will be installed:
  dkms linux-compiler-gcc-6-x86 linux-headers-4.9.0-1-amd64
  linux-headers-4.9.0-1-common linux-headers-amd64 linux-kbuild-4.9
  wireguard-dkms wireguard-tools


On jessie, it worked exactly the same with the 4.9 kernel from
jessie-backports:

# cat /etc/apt/sources.list
deb http://httpredir.debian.org/debian jessie main
deb http://httpredir.debian.org/debian jessie-backports main
deb http://httpredir.debian.org/debian unstable main
# cat /etc/apt/preferences.d/limit-unstable
Package: *
Pin: release a=unstable
Pin-Priority: 200
# apt update
# apt install -t jessie-backports linux-image-amd64 linux-base
# reboot
# apt install wireguard-dkms wireguard-tools
# ./client.sh
# ping 192.168.4.1
PING 192.168.4.1 (192.168.4.1) 56(84) bytes of data.
64 bytes from 192.168.4.1: icmp_seq=1 ttl=64 time=15.1 ms

For the record, it also works fine with the 4.1.34.mptcp kernel from
multipath-tcp.org on jessie :)

Jason, can you write something up on the Wireguard website, since it's so
simple?

interesting, thanks for testing and reporting back!

are you sure that with this installation on jessie, the wireguard
packages are the only things that got pulled in from unstable?

If you have apt-show-versions installed, you might try grepping through
its output to make sure.

Apologies for the delay. I tried pinning again on a fresh Stretch VM. It
looks like I confused myself by assuming that all the extra packages to be
installed were from sid as well, whereas -d shows that the vast majority
are coming from stretch/main. Sorry about the confusion, given this
behavior I completely agree that this should be the documented way to get
wireguard before stretch gets released as stable.

The transcript below still shows one additional package being pulled from
sid/main, the dkms package. I find this strange: wireguard-dkms depends on
dkms >=2.1.0.0, stretch has dkms 2.3-2, and sid has dkms 2.3-3. Despite the
negative priority for unstable, apt picks 2.3-3 from sid, even though the
dependency could be satisfied out of stretch. What am I missing?

Yes, it pulled only dkms and menu (from jessie).  Though I probably had
the other dependencies already installed (from jessie or jessie-backports).

Hey guys,

Very nice investigation. I think adding some simple instructions on
this to the WireGuard website makes sense. If you've got a one or two
or three or four line command to magically add these files and sync
the repos, could you send it along? Then I'll include it on the page.

That is indeed weird.  what does "apt-cache policy dkms" show you?

what if you "apt install dkms" on its own first, which version do you
get?

Looks like installing just dkms correctly selects from Stretch, whereas
installing as a dependency of wireguard-dkms pulls in the sid version.

I for one would love to be able to try WireGuard on Debian Jessie on 3.16
kernel.

The reason being is I do not see myself upgrading and/or running a
backported linux kernel for the foreseeable future.

Are there any limitations in 3.16 kernel when it comes to Wireguard
capabilities ?

Thanks,
