If a host key file is a symlink pointing to an as of yet non-existent
file, we don't want to remove it, but instead follow the symlink and
create the file at that location.
See https://github.com/nix-community/impermanence/issues/101 for more
information on the issue the original behavior creates.
Setting `cgroup-driver=systemd` was originally necessary to match with
docker, else the kubelet would not start (#111835)
However, since then, docker support has been dropped from k3s (#177790).
As such, this option is much less necessary.
More importantly, it now seems to be actively causing issues. Due to an
upstream k3s bug, it's resulting in the kubelet and containerd having
different cgroup drivers, which seems to result in some difficult to
debug failure modes.
See
https://github.com/NixOS/nixpkgs/issues/181790#issuecomment-1188840862
for a description of this problem.
Removing this flag entirely seems reasonable to me, and it results in
k3s working again on my machine.
The group configuration parameter allow to share access to yggdrasil
control socket with the users in the system. In the version we propose,
it is null by default so that only root can access the control socket,
but let user create their own group if they need.
Remove User= durective in systemd unit. Should a user with the specified
name already exist in the system, it would be used silently instead of a
dynamic user which could be a security concern.
Since version 0.4 Yggdrasil works again using systemd's DynamicUser option.
This patch reenables it to improve security.
We tested this with both persistent and non-persistent keys. Everything
seems to work fine.
The option `services.jira.sso.applicationPassword` has been replaced by
`applicationPasswordFile` that needs to be readable by the `jira`-user
or group.
The new `crowd.properties` is created on startup in `~jira` and the
secret is injected into it using `replace-secret`.
The current authentication code is broken against newer jenkins:
jenkins-job-builder-start[1257]: Asking Jenkins to reload config

jenkins-job-builder-start[1357]: curl: (22) The requested URL returned error: 403
Fix it by using `jenkins-cli` instead of messing with `curl`.
This rewrite also prevents leaking the password in process listings. (We
could probably do it without `replace-secret`, assuming `printf` is a
shell built-in, but this implementation should be safe even with shells
not having a built-in `printf`.)
Ref https://github.com/NixOS/nixpkgs/issues/156400.
Instead of hard-coding a single `configFile` for
`privacyidea-ldap-proxy.service` which is pretty unmergable with other
declarations it now uses a RFC42-like approach. Also to make sure that
secrets can be handled properly without ending up in the Nix store, it's
possible to inject secrets via envsubst
{
services.privacyidea.ldap-proxy = {
enable = true;
environmentFile = "/run/secrets/ldap-pw";
settings = {
privacyidea.instance = "privacyidea.example.org";
service-account = {
dn = "uid=readonly,ou=serviceaccounts,dc=example,dc=org";
password = "$LDAP_PW";
};
};
};
}
and the following secret file (at `/run/secrets`):
LDAP_PW=<super-secret ldap pw>
For backwards-compat the old `configFile`-option is kept, but it throws
a deprecation warning and is mutually exclusive with the
`settings`-attrset. Also, it doesn't support secrets injection with
`envsubst` & `environmentFile`.
It has been like this since the module was added, but it hasn't caused
problems because greetd assumes a default user of "greeter"[1] when it
isn't found anyway
[1]: d700309623/item/greetd/src/config/mod.rs (L127)
Suppose you want to provide a LDAP-based directory search to your
homeserver via a service-user with a bind-password. To make sure that
this doesn't end up in the Nix store, it's now possible to set a
substitute for the bindPassword like
services.mxisd.extraConfig.ldap.connection = {
# host, bindDn etc.
bindPassword = "$LDAP_BIND_PW";
};
and write the actual secret into an environment file that's readable for
`mxisd.service` containing
LDAP_BIND_PW=<your secret bind pw>
and the following setting in the Nix expression:
services.mxisd.environmentFile = "/runs/ecrets/mxisd";
(cherry picked from commit aa25ce7aa1a89618e4257fd46c7d20879f54c728)
...by using `replace-secret` instead of `sed` when injecting the
password into the ddclient config file. (Verified with `execsnoop`.)

* Update to the latest upstream version of pass-secret-service that includes
systemd service files.
* Add patch to fix use of a function that has been removed from the Python
Cryptography library in NixOS 22.05
* Install systemd service files in the Nix package.
* Add NixOS test to ensure the D-Bus API activates the service unit.
* Add myself as a maintainer to the package and NixOS test.
* Use checkTarget instead of equivalent custom checkPhase.
The `bash` binary is needed for running some plugins, notably the alarm notify plugins. If the binary isn't in the path, alarms notifications aren't sent and the netdata error log instead contains `/usr/bin/env: 'bash': No such file or directory`.
Due to lack of maintenance. It is not compatible with the default
Python version (due to the tornado 5) dependency, and doesn't look
like it will be any time soon.
I was under the impression that setting `services.redis.servers.<name>.save = []` would disable RDB persistence as no schedule would mean no persistence. However since the code did not handle this case specially it actually results in no `save` setting being written and the internal Redis default is used.
This patch handles the empty case to disable RDB persistence.
Disabling RDB persistence is useful in a number of scenarios:
1. Using Redis in a pure-cache mode where persistence is not desired.
2. When using the (generally superior) AOF persistence mode this file is never read so there is little point to writing it.
3. When saving is handled manually
For more information see https://redis.io/docs/manual/persistence/
This is a breaking change as the user may have been relying on `[]` using Redis defaults. However I believe that updating the behaviour for the next release is beneficial as IMHO it is less surprising and does what the user would expect. I have added release notes to warn about this change.
* nixos/vault: add option to start in dev mode.
This is not only useful for nixos tests i.e. when testing vault agent
setups but also when playing around with vault in local setups. In our
tests we can now make use of this option to test more vault features.
i.e. adding this feature has uncovered the need for a `StateDirectory`.
* Update nixos/modules/services/security/vault.nix

When using the example without the square brackets, nginx fails to start:
```
nginx-pre-start: nginx: [emerg] invalid port in "::1:80" of the "listen" directive in /nix/store/xyz-nginx.conf:29
nginx-pre-start: nginx: configuration file /nix/store/xyz-nginx.conf test failed
```
* Update attribute names in code examples (* -> settings.*).
* Use `nix-shell -p` rather than `nix run` because the example won't
work with the current default Nix.
* Update config values for `element-web`.
* Fix link to `element-web` security considerations.
* Make the synapse expression even smaller and use callout-lists to
explain the code.
* Document how to correctly deploy the shared registration secret.

Running `nixos/tests/keepassxc.nix` shows:
```
machine # [ 18.705390] xsession[985]: /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession: line 13: nn: command not found
```
This garbled bash script runs without `set -o errexit` and thus skips
"\n\n" as invalid command:
```
$ cat -n /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession
...
\n\n
if [ -e $HOME/.background-image ]; then

fi
...
```
KeePassXC uses it through
`nixos/modules/services/x11/display-managers/default.nix`:
```
...
# Script responsible for starting the window manager and the desktop manager.
xsession = dm: wm: pkgs.writeScript "xsession" ''
#! ${pkgs.bash}/bin/bash
# Legacy session script used to construct .desktop files from
# `services.xserver.displayManager.session` entries. Called from
# `sessionWrapper`.
# Start the window manager.
${wm.start}
# Start the desktop manager.
${dm.start}
...
'';
...
```
The bogus line was introduced in PR #160752:
```
commit 0bc0dc8090
Author: Shaw Vrana <shaw@vranix.com>
Date: Fri Feb 18 11:27:42 2022 -0800
desktop manager script: start properly
Adds a missing line feed when X is enabled to the start script name
and the appended if check. Resolves#160735
```
I have not tried to reproduce the original issue and thus don't know
why "\n\n" apparently gets interpreted fine in one place but remains
literal the `xsession` case.
However, using a literal newline must be valid for all cases and
certainly fixes the warning seen in KeePassXC tests.
Furthermore, starting the nix string (`''`) with a newline as usual also
fixes its overall indentation.
