Similar to the `user` option, the added `group` option sets the group of
the executing process. If not `null`, it also sets `DynamicUser=false`.
In case `user` is set to `null` (the default), systemd would run the
service as root implicitly. As this is dangerous and most certainly not
what users want, we force them to set `user = "root"` explicitly if
that's really their intention. That's achieved through an assertion.
After 4b128008c5 it took me a while in a
test setup to find out why `root` didn't have the password anymore I
declared in my config.
Because of that I got reminded how the order of preference works for the
password options:
hashedPassword > password > hashedPasswordFile
If the user is new, initialPassword & initialHashedPassword are also
relevant. Also, the override is silent in contrast to any other
conflicting definition in NixOS.
To make this less surprising I decided to warn in such a case -
assertions would probably break too much that technically works as
intended.
Also removed the `initialHashedPassword` for `root`. This would cause a
warning whenever you set something in your own config and a `!` is added
automatically by `users-groups.pl`.
`systemd-sysusers` also seems to implement these precedence rules, so
having the warning for that case also seems useful.
The `github-runner` package only supports `nodejs_20` since `nodejs_16`
was removed in a2976db919.
It still makes sense to keep the `nodeRuntimes` option as this is
probably not the last Node.js we'll deprecate with at least some grace
period.
Exposes two options, `path` and `mode`, to configure the location and
permissions on the socket file.
The `mode` needs to be specified as string in octal and will be converted
into a decimal integer, so it correctly passes through the YAML parser
and arrives at the `os.chmod` call in the Twisted codebase. What a fun
detour.
Adds an assertion, that either `path` or `bind_addresses` and `port` are
configured on every listener.
Migrates the default replication listener of the main instance to a UNIX
domain socket, because it is more efficient.
Introduces the `enableRegistrationScript` option, to gracefully disable
the user registration script, when the client listener listens on a UNIX
domain socket, which is something the script does not support.
- Make the token a required option
- Drop the proto from the listen parameter
- Use systemd credentials to pass the token file
- Drop debug flag, use extraArgs instead
- Actually hook up extraArgs
- Escape shell arguments
- Drop overly broad `with lib` statement
Gitlab stays running at redis and postgresql restarts as if these
components were on a different host anyways. Handling reconnetctions is
part of the application logic.

right now, we have php81 and php (which points to php82), which means that:
- php-fpm uses php81
- the update preStart uses php81
- the actual updater uses php82
This change replaces the previously hard-coded `/boot` path with a
reference to `efiSysMountPoint` and more importantly this change makes
it possible to override these rules in scenarios in which they are not
desired.
One such scenario would be when `systemd-gpt-auto-generator(8)` is used
to automount the ESP. Consider this section from the mentioned manpage:
> The ESP is mounted to /boot/ if that directory exists and is not used
> for XBOOTLDR, and otherwise to /efi/. Same as for /boot/, an automount
> unit is used. The mount point will be created if necessary.
Prior to this change, the ESP would be automounted under `/efi` on first
boot, then the previous tmpfiles rules caused `/boot` to be created.
Following the quote above, this meant that the ESP is mounted under
`/boot` for each subsequent boot.
A recent release added systemd notify support, so I migrated our unit
towards that. The NixOS test did not reveal that the unit would not fully
activate.

Closes: #286977
Murmur provides an official systemd service file in their repo,
which contains various service hardening settings:
c4b5858d14/auxiliary_files/config_files/mumble-server.service.in (L7)
The service configuration in nixpkgs does not include these hardening settings.
This commit adds the hardening settings to the murmur service in nixpkgs.
This drops the `systemd-analyze security` score of murmur.service from 9.2 (UNSAFE) to 2.1 (OK).
* Make services.archisteamfarm.bots.*.passwordFile Nullable
This adds support for alternate password specification methods, such as through the web-ui.
* Update description for services.archisteamfarm.bots.*.passwordFile
Adds note about omitting or setting to null to provide the password through the web-ui.
Not a mkRenamedOptionModule, because user intervention is required
to determine whether they have a problem. mkRenamed* does not let
us explain anything to the user.
Currently there are a bunch of really wacky hacks required to get nixpkgs
path correctly set up under flake configs such that `nix run
nixpkgs#hello` and `nix run -f '<nixpkgs>' hello` hit the nixpkgs that
the system was built with. In particular you have to use specialArgs or
an anonymous module, and everyone has to include this hack in their
own configs.
We can do this for users automatically.
I have tested these manually with a basic config; I don't know if it is
even possible to write a nixos test for it since you can't really get a
string-with-context to yourself unless you are in a flake context.
Older versions of the github-runner package might not have the
`nodeRuntimes` argument yet causing an error as the NixOS module always
tries to override the argument.
The commit makes sure we only override `nodeRuntimes` if the configured
package has a `nodeRuntimes` argument.
With DefaultDependencies enabled, systemd adds "After=basic.target" to
service units. `basic.target` has a dependency on `sockets.target`, so
the `nftables` has (amongst others) the following order constraints:
* Before=network-pre.target
* After=sockets.target
Those constraints are often unsatisfiable. For example, `systemd-networkd`
has a dependency `After=network-pre.target`. When a socket unit now uses
`BindToDevice=` on a device managed by `networkd`, a timeout occurs
because `networkd` waits for `network-pre.target`, but
`network-pre.target` depends (through nftables) on `sockets.target`, but
the device to bind the socket to is never brought up, as this would
happen through `networkd`.
This is fixed by removing the implicit dependency on `basic.target`.
Lists are convenient to have in sysupdate configuration when using
multiple `MatchPattern` under `Target` when the target can have multiple
filenames. This use-case is helpful for BootLoaderSpec bootcounting where the target file on
disk can have multiple filenames, and in order for sysupdate to properly
ensure only N number of instances of this target exist at one time, we
need to have multiple match patterns.
Previously any user-provided config for boot.uki.settings would need to
either specify a full set of config for ukify or a combination of
mkOptionDefault to merge the "settings" attribute set with the module's
defaults and then mkOverride or mkForce to override a contained
attribute.
Now it is possible to trivially override parts of the module's default
config, such as the initrd or kernel command line, but overriding the
full set of settings now requires mkOverride / mkForce.
Even if the tools that assemble /etc can handle leading slashes, this
still is not correct. For example, you could have both /X11 and X11 in
environment.etc which makes overriding hard.
Borrowing from here to match hardened profile with more recent kernels:
* https://madaidans-insecurities.github.io/guides/linux-hardening.html?#boot-parameters
* https://github.com/a13xp0p0v/kernel-hardening-checker/
Removed "slub_debug" as that option disables kernel memory address
hashing. You also see a big warning about this in the dmesg:
"This system shows unhashed kernel memory addresses via the console, logs, and other interfaces."
"init_on_alloc=1" and "init_on_free=1" zeroes all SLAB and SLUB allocations. Introduced in 6471384af2a6530696fc0203bafe4de41a23c9ef. Also the default for the Android Google kernel btw. It is on by default through the KConfig.
"slab_nomerge" prevents the merging of slab/slub caches. These are
effectively slab/slub pools.
"LEGACY_VSYSCALL_NONE" disables the older vsyscall mechanic that relies on
static address. It got superseeded by vdsos a decade ago. Read some
LWN.net to learn more ;)
"debugfs=off" I'm sure there are some few userspace programs that rely on
debugfs, but they shouldn't.
Most other things mentioned on the blog where already the default on a
running machine or may not be applicable.
Most other Kconfigs changes come from the kernel hardening checker and
were added, when they were not applied to the kernel already.
Unsure about CONFIG_STATIC_USERMODEHELPER. Would need testing.
This will gracefully shut down the service instead of resulting in errors like
this:
```

The current build of livebook does not work with the new [Livebook
Teams](https://livebook.dev/teams/) features. The problem can be observed by
running the current version of livebook, adding a new team and going to the team
page. The process will crash and the team page will show a 500 error.
The base of the problem is that the escript build method is not officially
supported. This commit changes the livebook package to use the `mix release`
workflow, which is also the one used to build the official Docker container.
Unfortunately, the binary built with `mix release` does not support command line
arguments like the `escript` binary does. Instead, users need to pass in most of
the configuration as environment variables, as documented
[here](https://hexdocs.pm/livebook/readme.html#environment-variables). As a
result, this commit also changes the Livebook service to reflect this new way of
configuring Livebook.
Finally, the Livebook release configuration specifically excludes the
ERTS (Erlang Runtime System), which means that the resulting release cannot run
without Erlang installed.
I have tested the results (both of the package and the service) locally.
Since this is supposed to be a secret, use a file path as an input
instead of making it part of the expression, which would expose it in
the nix store.
There were several modules, critically including NetworkManager, which
were not prepared for this change. Most of the change was good,
however. Let's bring back the dependency and change the assertion to a
warning for now.
Plugin configuration is pesky in dovecot2, let's warn about potential conflicts
in the module system by using a fancy regex.
This is only band-aid, this should be removed ASAP.
We clean up also a 21.05-era warning.
Just moved to hyprland module to programs/wayland.
This has no effect on the module side (still accessed the same way in
the module `programs.hyprland`) just moved to be inline with other
wayland compositors.
Also edit the module list to reflect where the file is located.
The fwupd daemon refuses to start when there is an uefi_capsule key without any
values in the config file, so I modified the module to only include this
key when there are actually values that go inside.
