the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
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.
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.
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`.)

verbose is a debugging setting one step noisier than debug and should only be turned on when debugging because it leaks quite some credentials and tokens in the journalctl.
we expose it under settings instead of at the listener toplevel because
mosquitto seems to pick the addresses it will listen on
nondeterministically from the set of addresses configured on the
interface being bound to. encouraging its use by putting it into the
toplevel options for a listener seems inadvisable.

Tailscale uses policy routing to enable certain traffic to bypass
routes that lead into the Tailscale mesh. NixOS's reverse path
filtering setup doesn't understand the policy routing at play,
and so incorrectly interprets some of this traffic as spoofed.
Since this only breaks some features of Tailscale, merely warn
users about it, rather than make it a hard error.

In a previous PR [1], the conditional to generate a new host key file
was changed to also include the case when the file exists, but has zero
size. This could occur when the system is uncleanly powered off shortly
after first boot.
However, ssh-keygen prompts the user before overwriting a file. For
example:
$ touch hi
$ ssh-keygen -f hi
Generating public/private rsa key pair.
hi already exists.
Overwrite (y/n)?
So, lets just try to remove the empty file (if it exists) before running
ssh-keygen.

We remove the various lua wrappers introduced by

We should probably think about the migration from http_upload to
http_file_share for the NixOS module. It's not trivial, we need to

This commit refactors the way how configuration files are deployed to
the `/etc/asterisk` directory.
The current solution builds a Nix derivation containing all config files
and symlinks it to `/etc/asterisk`. The problem with that approach is
that it is not possible to provide additional configuration that should
not be written to the Nix store, i.e. files containing credentials.
The proposed solution changes the creation of configuration files so
that each configuration file gets symlinked to `/etc/asterisk`
individually so that it becomes possible to provide additional config
files to `/etc/asterisk` as well.
This avoids the scenario where you activate a new config over Tailscale,
and a long delay between the "stop services" and "start services" phases
of the activation script lead to your terminal freezing for tens of
seconds, until tailscaled finally gets started again and the session
recovers.
Per the documentation of stopIfChanged, this is only safe to do if the
service definition is robust to stopping the old process using the new
service definition. As the maintainer of the upstream systemd unit, I
can confirm that Tailscale is robust to this scenario: it has to be
in order to work right on several other distros that just do
unpack-then-restart, rather than the more complex stop-unpack-start
dance.

using freeform is the new standard way of using modules and should replace

This adds the option `networking.wg-quick.interfaces.<name>.autostart`, which defaults to `true`, which is the previous behavior. With this option set to `false`, the systemd-unit will no longer be set to `wantedBy = [ "multi-user.target" ]` and therefore the tunnel has to be enabled/disabled via `systemctl start/stop wg-quick-<name>`.

Since b9cfbcafdf, the lack of hexdump in
the closure lead to the generation of empty cookie files. This empty
cookie file is making pleroma to crash at startup now we correctly
read it.
We introduce a migration forcing these empty cookies to be
re-generated to something not empty.
We inject the release cookie path to the pleroma derivation in order
to wrap pleroma_ctl with it. Doing this allows us to remove the
systemd-injected RELEASE_COOKIE path, which was sadly
buggy (RELEASE_COOKIE should point to the *content* of the cookie, not
the file containing it).
We take advantage of this to factor out the cookie path.
Now, one can just use `networking.networkmanager.plugins = lib.mkForce [];`
if they want to get rid of the plug-ins.

New ntopng version supports running as specified user. Create a separate
user for ntopng with a separate Redis instance.
Separate instance is only used for new `system.stateVersion`s to avoid
breaking existing setups. To configure that we add two new options,
`redis.address` and `redis.createInstance`. They can also be used to
specify your own Redis address.
The module option type `nonEmptyStr` was introduced in commit
a3c5f0cba8
The hylafax module previously simply used
`addCheck str (s: s!="")` to prevent empty option strings,
but the new type is more thorough as
it also catches space-only strings.
I think calling i2pd directly in `ExecStart` is much nicer than having an extra shell script for no reason. It's also easier to see what's going on when looking at the generated systemd unit file.
* nixos/nftables: Allow use with iptables
Since iptables and nftables do not actually conflict with each other, there's no real reason to artificially prevent people from combining them.
In fact, this practice is known to cause issues like #88643, which is fixed by this commit.
Empty parantheses are not supported in regular expressions on
Darwin/macOS. The old regular expression produces an error during
evaluation. This commit fixes that.
Nix‘s `builtins.match` works with extend POSIX regular expressions. The
specification for these regular expression states[^1] that the result
for a left paranthesis immediately followed by a right paranthesis
outside of a bracket expression is undefined.

Since release 1.18.4, the ModemManager daemon no longer automatically
performs the FCC unlock procedure by default. The user must, under their
own responsibility, enable the automatic FCC unlock as shipped by
ModemManager.
Add a new type, inheriting 'types.str' but checking whether the value
doesn't contain any newline characters.
The motivation comes from a problem with the
'users.users.${u}.openssh.authorizedKeys' option.
It is easy to unintentionally insert a newline character at the end of a
string, or even in the middle, for example:
restricted_ssh_keys = command: keys:
let
prefix = ''
command="${command}",no-pty,no-agent-forwarding,no-port-forwarding,no-X11-forwarding
'';
in map (key: "${prefix} ${key}") keys;
The 'prefix' string ends with a newline, which ends up in the middle of
a key entry after a few manipulations.
This is problematic because the key file is built by concatenating all
the keys with 'concatStringsSep "\n"', with result in two entries for
the faulty key:
''
command="...",options...
MY_KEY
''
This is hard to debug and might be dangerous. This is now caught at
build time.
network.target is reached earlier, but with much fewer services
available. DNS is likely to be not functional before
network-online.target, so waiting for that seems better for that reason
alone. the existing backends for network-online.target all seem to do
reasonable things (wait until all links are in *some* stable state), so
we shouldn't lose anything from waiting.

It turns out it's actually possible to fall back to WPA2 in case the
authentication fails with WPA3. This was suggested to me in the hostapd
mailing list: add another network block with only WPA2 and lower
priority, for each network with WPA3. For clients with missing/broken
WPA3, wpa_supplicant will:
1. try the network block with higher priority first
2. fail and temporarily disable the network block
3. try the fallback network block and connect
This takes a little more time (still <5s) because wpa_supplicant
retries a couple times before disabling the network block, but it allows
old client to gracefully fall back to WPA2 on mixed WPA2/WPA3 networks.
To avoid downgrade attacks, clients with proper WPA3 should disable
this; in the future we may want to disable this option by default.
This is a useful utility for monitoring network performance over time
using a combination of MTR and Prometheus. Also adding a service definition.

Alternative solution to PR #152443.
This fixes authentication failures to WPA3 networks (issue #151729)
by enabling protected management frames.
Note: old client without 802.11w support will still fail.
When startWhenNeeded is enabled, a brute force attack on sshd will cause
systemd to shut down the socket, locking out all SSH access to the machine.
Setting TriggerLimitIntervalSec to 0 disables this behavior.
This never configured where SNI should log to, as it's up to the user to
provide the full sniproxy config (which can be configured to log to a
file).
This option only produced a ExecStartPre script that created the folder.
Let's use LogsDirectory to create it. In case users want to use another
directory for logs, they can override LogsDirectory or set their own
ExecStartPre script.
The systemd syntax is suprising to me, but I suppose it's worth being
compatible as people might be sharing it with other modules.
Our regexp is lenient on IPv6 address part, so this is actually
backwards compatible (i.e. you can put the scope at either place).
dhcpcd does not run properly with some of the hardened system mallocs
that are currently available. assert when an incompatible configuration
is detected, as a switch into such a config from eg auto-update can take
hosts offline.
link to search.nixos.org instead of pulling package metadata out of pkgs. this
lets us cache docs of a few more modules and provides easier access to package
info from the HTML manual, but makes the manpage slightly less useful since
package description are no longer rendered.
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.
in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.
Sometimes it is preferable to configure forwarding only for bind
instead of relying on direct lookups.
This patch makes it possible to configure the forward setting to
either "first" (the default) or "only".
This commit introduces `services.adguardhome.settings` and
`services.adguardhome.mutableSettings`.
The first option allows declarative configuration of
AdGuard Home, while the second one controls whether changes
made in the web interface are kept between service restarts.

- Add docs on using new defaults option to configure

- Update DNS docs to show using a service to configure

openFirewall is the much more common name for an option with this
effect. since the default was `true` all along, renaming it doesn't hurt
much and only improves consistency with other modules.
some options have default that are best described in prose, such as
defaults that depend on the system stateVersion, defaults that are
derivations specific to the surrounding context, or those where the
expression is much longer and harder to understand than a simple text
snippet.
escape interpolations in descriptions where possible, replace them with
sufficiently descriptive text elsewhere. also expand cfg.* paths in
descriptions.

Does this not completely break the service? It doesn't change the
owner to the same as the ddclient server (which is somewhat difficult
due to it being a DynamicUser), so this now makes the service
completely unusable because the config is only readable by its owner,
root:
ddclient[871397]: WARNING: file /run/ddclient/ddclient.conf: Cannot open file '/run/ddclient/ddclient.conf'. (Permission denied)
Given that the RuntimeDirectory was only readable by the ddclient
service, the warning this PR fixes was spurious and not indicative of
an actual information leak. I'm not sure of what a quick fix would be
due to DynamicUser, but would at least request a revert of this so the
service can work again?
