Well, this should test if the database is encrypted but currently it is
still unencrypted and we need to notice if this behaviour changes in the
future (as it will cause data loss, see e.g. #108772).
Anyway, this doesn't really matter for security reasons but we need this
test to prevent data loss (unfortunately Signal-Desktop and SQLCipher
handle this badly... :o).
This test is important to confirm that $WAYLAND_DISPLAY is correctly
imported via "dbus-update-activation-environment --systemd" which is
done by default since #122605 (00e8e5b123f).
It ensures that the gnome3-pinentry pop-ups work as expected to avoid
regressions like #119445 (which also broke screen sharing).
The distinction between the inputs doesn't really make sense in the
mkShell context. Technically speaking, we should be using the
nativeBuildInputs most of the time.
So in order to make this function more beginner-friendly, add "packages"
as an attribute, that maps to nativeBuildInputs.
This commit also updates all the uses in nixpkgs.
Both networking.nat.enable and virtualisation.docker.enable now want to
make sure that the IP forwarding sysctl is enabled, but the module
system dislikes that both modules contain this option.
Realistically this should be refactored a bit, so that the Docker module
automatically enables the NAT module instead, but this is a more obvious
fix.
The essential commands from the NixOS installer as a package
With this package, you get the commands like nixos-generate-config and
nixos-install that you would otherwise only find on a NixOS system, such
as an installer image.
This way, you can install NixOS using a machine that only has Nix.
It also includes the manpages, which are important because the commands
rely on those for providing --help.
The default config.in template contains
"include @sysconfdir@/sway/config.d/*" but we've dropped it to better
support non-NixOS (which seems like a mistake in retrospect).
This restores that behaviour and extends the default configuration via
nixos.conf to fix#119445.
Note: The security configurations (security.d) where dropped entirely
(but maybe they'll return).
* add an example for services.tor.settings.HidServAuth
* fix HidServAuth validation to require ".onion"
Per https://manpages.debian.org/testing/tor/torrc.5.en.html :
> Valid onion addresses contain 16 characters in a-z2-7 plus ".onion"
ssm-agent expects files in /etc/amazon/ssm. The pkg substitutes a location in
the nix store for those default files, but if we ever want to adjust this
configuration on NixOS, we'd need the ability to modify that file.
This change to the nixos module writes copies of the default files from the nix
store to /etc/amazon/ssm. Future versions can add config, but right now this
would allow users to at least write out a text value to
environment.etc."amazon/ssm/amazon-ssm-agent.json".text to provide
their own config.
config.boot.kernelPackages.wireguard evaluates to null on machine
closure having a > 5.6 Linux kernels, hence making the evaluation of
this test fail.
Wireguard is now part of the mainline Linux kernel, we do not need to
to add it via a additional kernel module anymore for this test.
Annoyed with the interference of the python formatting of
generated code (see #72964), I took matters into my own hands
as maintainer of dockerTools.
Afterwards, I've created a PR, hoping to unstuck the discussion.
@aszlig took notice and thanks to his python ecosystem knowledge,
the testing efforts of @blaggacao and @Ma27, and a sense of
shared suffering and comraderie we were able to change the
situation for the better in #122201.
Now, we have a proper linter that actually helps contributors,
so it's time to turn it back on again.
I'm glad we could make it happen this quickly!
Thanks!
This reverts commit 4035049af3e45554ffc4d8b4c30fd43ae9cd328a.
There were a bunch of unnecessary f-strings in there and I also removed
the "# fmt: on/off" comments, because we no longer use Black and thus
won't need those comments anymore.

The new linter basically does
def testScript
# ...
before calling `pyflakes`. As this test-script is empty, it would lead
to a syntax-error unless `pass` is added.
Our test driver exposes a bunch of variables and functions, which
pyflakes doesn't recognise by default because it assumes that the test
script is executed standalone. In reality however the test driver script
is using exec() on the testScript.
Fortunately pyflakes has $PYFLAKES_BUILTINS, which are the attributes
that are globally available on all modules to be checked. Since we only
have one module, using this environment variable is fine as opposed to
my first approach to this, which tried to use the unstable internal API
of pyflakes.
The attributes are gathered by the main derivation of the test driver,
because we don't want to end up defining a new attribute in the test
driver module just to being confused why using it in a test will result
in an error.
Another way we could have gathered these attributes would be in
mkDriver, which is where the linting takes place. However, we do have a
different set of Python dependencies in scope and duplicating these will
again just cause confusion over having it at one location only.

So far, we have used "black" for formatting the test code, which is
rather strict and opinionated and when used inline in Nix expressions it
creates all sorts of trouble.
One of the main annoyances is that when using strings coming from Nix
expressions (eg. store paths or option definitions from NixOS modules),
completely unrelated changes could cause tests to fail, since eg. black
wants lines to be broken.
Another downside of enforcing a certain kind of formatting is that it
makes the Nix expression code inconsistent because we're mixing two
spaces of indentation (common in nixpkgs) with four spaces of
indentation as defined in PEP-8. While this is perfectly fine for
standalone Python files, it really looks ugly and inconsistent IMO when
used within Nix strings.
What we actually want though is a linter that catches problems early on
before actually running the test, because this is *actually* helping in
development because running the actual VM test takes much longer.
This is the reason why I switched from black to pyflakes, because the
latter actually has useful checks, eg. usage of undefined variables,
invalid format arguments, duplicate arguments, shadowed loop vars and
more.

I left one case due to fetching from their personal repo:

Since v2021.5.0 home-assistant uses the ifaddr library in the zeroconf
component to enumerate network interfaces via netlink. Since discovery
is all over the place lets allow AF_NETLINK unconditionally.
It also relies on pyroute2 now, which additionally tries to access files
in /proc/net, so we relax ProtectProc a bit by default as well.
This leaves us with these options unsecured:
✗ PrivateNetwork= Service has access to the host's network 0.5
✗ RestrictAddressFamilies=~AF_(INET|INET6) Service may allocate Internet sockets 0.3
✗ DeviceAllow= Service has a device ACL with some special devices 0.1
✗ IPAddressDeny= Service does not define an IP address allow list 0.2
✗ PrivateDevices= Service potentially has access to hardware devices 0.2
✗ PrivateUsers= Service has access to other users 0.2
✗ SystemCallFilter=~@resources System call allow list defined for service, and @resources is included (e.g. ioprio_set is allowed) 0.2
✗ RestrictAddressFamilies=~AF_NETLINK Service may allocate netlink sockets 0.1
✗ RootDirectory=/RootImage= Service runs within the host's root directory 0.1
✗ SupplementaryGroups= Service runs with supplementary groups 0.1
✗ RestrictAddressFamilies=~AF_UNIX Service may allocate local sockets 0.1
✗ ProcSubset= Service has full access to non-process /proc files (/proc subset=) 0.1
→ Overall exposure level for home-assistant.service: 1.6 OK 🙂
libbrotli wasn't listed as a dependency for the AppArmor profile of the transmission-daemon binary.
As a result, transmission wouldn't run and would fail, logging this audit message to dmesg:
