find-libs is currently choking when it finds the dynamic linker
as a DT_NEEDED dependency (from glibc) and bails out like this
(as glibc doesn't have a RPATH):
Couldn't satisfy dependency ld-linux-x86-64.so.2
Actually the caller of find-libs ignores the exit status, so the issue
almost always goes unnoticed and happens to work by chance. But
additionally what happens is that indirect .so dependencies are
left out from the dependency closure calculation, which breaks
latest cryptsetup as libssl.so isn't found anymore.
Kubernetes dashboard currently has cluster admin permissions,
which is not recommended.
- Renamed option "services.kubernetes.addons.dashboard.enableRBAC" to "services.kubernetes.addons.dashboard.rbac.enable"
- Added option "services.kubernetes.addons.dashboard.rbac.clusterAdmin", default = false.
- Setting recommended minimal permissions for the dashboard in accordance with https://github.com/kubernetes/dashboard/wiki/Installation
- Updated release note for 18.09.
Adds a module for running the journaldriver log forwarding agent via
systemd.
The agent can be deployed on both GCP instances and machines hosted
elsewhere to forward all logs from journald to Stackdriver Logging.
Consult the module options and upstream documentation for more
information.
Implementation notes:
* The service unit is configured to use systemd's dynamic user feature
which will let systemd set up the state directory and appropriate
user configuration at unit launch time instead of hardcoding it.
* The module depends on `network-online.target` to prevent a situation
where journaldriver is failing and restarting multiple times before
the network is online.
- Added option 'cni.configDir' to allow for having CNI config outside of nix-store
Existing behavior (writing verbatim CNI conf-files to nix-store) is still available.
- Removed unused option 'apiserver.publicAddress' and changed 'apiserver.address' to 'bindAddress'
This conforms better to k8s docs and removes existing --bind-address hardcoding to 0.0.0.0
- Fixed c/p mistake in apiserver systemd unit description
- Updated 18.09 release notes to reflect changes to existing options
And fixed some typos from previous PR
- Make docker images for Kubernetes Dashboard and kube-dns configurable
The usage of nixpkgs.config.packageOverrides is deprecated and we do
have overlays since quite a while.

This reverts a part of 5bd12c694b.
Apparently there's no way to specify user for RuntimeDirectory in systemd
service file (it's always root) but tor won't create control socket if the dir
is owned by anybody except the tor user.
These hardenings were adopted from the upstream service file, checked
against systemd.service(5) and systemd.exec(5) manuals, and tested to
actually work with all the options enabled.
`PrivateDevices` implies `DevicePolicy=closed` according to systemd.exec(5),
removed.
`--RunAsDaemon 0` is the default value according to tor(5), removed.
The `zsh-autosuggestions` package provides several configuration options
such as a different highlight style (like `fg=cyan` which is easier to
read).
With `rename.nix` the old `programs.zsh.enableAutosuggestions` is still
functional, but yields the following warning like this during evaluation:
```
trace: warning: The option `programs.zsh.enableAutosuggestions' defined in `<unknown-file>' has been renamed to `programs.zsh.autosuggestions.enable'.
```
The module provides the most common `zsh-autosuggestions` (highlight
style and strategy) as options that will be written into the interactive
shell init (`/etc/zshrc` by default). Further configuration options can
be declared using the `extraConfig` attr set:
```
{
programs.zsh.autosuggestions.extraConfig = {
"ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE" = "buffer_size";
};
}
```
A full list of available configuration options for `zsh-autosuggestions`
can be viewed here: https://github.com/zsh-users/zsh-autosuggestions/blob/v0.4.3/README.md
[x] Support transparent proxying. This means services behind sslh (Apache, sshd and so on) will see the external IP and ports as if the external world connected directly to them.
[x] Run sslh daemon as unprivileged user instead of root (it is not only for security, transparent proxying requires it)
[x] Removed pidFile support (it is not compatible with running sslh daemon as unprivileged user)
[x] listenAddress default changed from "config.networking.hostName" (which resolves to meaningless "127.0.0.1" as with current /etc/hosts production) to "0.0.0.0" (all addresses)
Adds programs.mosh.withUtempter (default: true).
The option enables -with-utempter for mosh, allowing it to write to
/var/run/utmp and thus making connected sessions appear in the output
of `who -a`.
For that, a guid-wrapper is required. Also, the path to the `utempter` was
hardcoded in the resulting binary until now (so it could never been found),
thus, libutempter was patched accordingly to point to
/run/wrappers/bin/utempter which at least works when the wrapper is
configured.

DBus seems to resolve user IDs directly via glibc, circumventing nscd. In more
advanced setups this leads to user's coming from LDAP or SSSD not being
resolved by the dbus system bus daemon. The effect for such users is, that all
access to the system bus (e.g. busctl or nmcli) is denied.
Adding the respective NSS modules to the service's environment solves the issue
the same way it does for nscd.

The correct way to override a single value would be to use something
like this:
systemd.services.nagios.serviceConfig.Restart = lib.mkForce "no";
However, this doesn't work because the check is applied for the attrsOf
type and thus the attribute values might still contain the attribute set
created by mkOverride.
The unitOption type however did already account for this, but at this
stage it's already too late.
So now the actual value is unpacked while checking the values of the
attribute set, which should allow us to override values in
serviceConfig.

The nixos module adds a new derivation to
systemPackages to make sure that the binaries
get the generated config file. This derivation
did not contain the man pages so far.
Activating the module now makes the man pages
available in the system environment.
This change allows users to specify an alternative database method. For
example an mpd satellite setup where another mpd on the network shares
it's database with the local instance. The `dbFile` parameter must not be
configured in that case.
BIND doesn't allow the options section (or any section I'd guess) to be
defined more than once, so whenever you want to set an additional option
you're stuck using weird hacks like this:
services.bind.forwarders = lib.mkForce [ "}; empty-zones-enable no; #" ];
This basically exploits the fact that values coming from the module
options aren't escaped and thus works in a similar vain to how SQL
injection works.
Another option would be to just set configFile to a file that includes
all the options, including zones. That obviously makes the configuration
way less extensible and more awkward to use with the module system.
To make sure this change does work correctly I added a small test just
for that. The test could use some improvements, but better to have a
test rather than none at all. For a future improvement the test could be
merged with the NSD test, because both use the same zone file format.
This change has been reviewed in #40053 and after not getting any
opposition, I'm hereby adding this to master.

Ideally I'd like the whole `nixos`/`nixpkgs` channel distinction to disappear, but this is a step along that path. After a while being in this state, we can stop creating the magic `nixpkgs -> .` symlink inside our `nixos` channel tarballs and simplify that whole mess a bit.
Wireguard is now split into two pretty much independent packages:

`xsslock` (which was originally packaged in 6cb1d1aaaf)
is a simple screensaver which connects a given screen locker (e.g.
`i3lock`) with `logind`. Whenever `loginctl lock-sessions` is invoked
the locker will be used to lock the screen. This works with its power
management features (e.g. `lid switch`) as well, so the PC can be locked
automatically when the lid is closed.
The module can be used like this:
```
{
services.xserver.enable = true;
programs.xss-lock.enable = true;
programs.xss-lock.lockerCommand = "i3lock";
}
```
My c6f7d43678 made the mistake of not

the other default (projected), as that would cause a cycle, but `{
system = builtins.currentTime; }` just as nixpkgs itself does it.

When doing source routing/multihoming, it's practical to give names to routing

The original `nexus` derivation required `/run/sonatype-work/nexus3`
which explicitly depended on the NixOS path structure.
This would break `nexus` for everyone using `nixpkgs` on a non-NixOS
system, additionally the module never created `/run/sonatype-work`, so
the systemd unit created in `services.nexus` fails as well. The issue
wasn't actively known as the `nixos/nexus` test wasn't registered in
Hydra (see #40257).
This patch contains the following changes:
* Adds `tests.nexus` to `release.nix` to run the test on Hydra.
* Makes JVM parameters configurable: by default all JVM options were located
in `result/bin/nexus.vmoptions` which made it quite hard to patch
these parameters. Now it's possible to override all parameters by
running `VM_OPTS_FILE=custom-nexus.vmoptions ./result/bin/nexus run`
(after patching the `nexus` shell script), additionally it's possible
to override these parameters with `services.nexus.vmoptions`.
* Bumped Nexus from 3.5.1 to 3.11.0
* Run the `nexus` test on Hydra with `callTest` in `nixos/release.nix`,
furthermore the test checks if the UI is available on the specified
port.
* Added myself as maintainer for the NixOS test and the package to have

The pull request that added dhparams (#39507) was made at the time where
the dhparams module overhaul (#39526) wasn't done yet, so it's still
using the old mechanics of the module.
As stated in the release notes:
Module implementers should not set a specific bit size in order to let
users configure it by themselves if they want to have a different bit
size than the default (2048).
An example usage of this would be:
{ config, ... }:
{
security.dhparams.params.myservice = {};
environment.etc."myservice.conf".text = ''
dhparams = ${config.security.dhparams.params.myservice.path}
'';

Regression introduced by d4468bedb5.
No systemd messages are shown anymore during VM test runs, which is not
very helpful if you want to find out about failures.
There is a bit of a conflict between testing and the change that
introduced the regression. While the mentioned commit makes sure that
the primary console is tty0 for virtualisation.graphics = false, our VM
tests need to have the serial console as primary console.
So in order to support both, I added a new virtualisation.qemu.consoles
option, which allows to specify those options using the module system.
The default of this option is to use the changes that were introduced
and in test-instrumentation.nix we use only the serial console the same
way as before.
For test-instrumentation.nix I didn't add a baudrate to the serial
console because I can't find a reason on top of my head why it should
need it. There also wasn't a reason stated when that was introduced in
7499e4a5b9.

after seeing
`adjtime failed: Invalid argument` in my syslog, I tried using
`ntpd -s` but it would trigger
`/etc/ntpd.conf: No such file or directory`
see https://github.com/NixOS/nixpkgs/issues/31885
Instead of running the daemon with a specific config file, use the
standard file so that user are able to use the ntp executable without
having to look for the current config file.
Tracking scripts in particular, cannot be included in extraOpts, because script declaration has to be above script usage in keepalived.conf.
Changes are fully backward compatible.
This introduces an option that allows us to turn off stateful generation
of Diffie-Hellman parameters, which in some way is still "stateful" as
the generated DH params file is non-deterministic.
However what we can avoid with this is to have an increased surface for
failures during system startup, because generation of the parameters is
done during build-time.
Aside from adding a NixOS VM test it also restructures the type of the
security.dhparams.params option, so that it's a submodule.
A new defaultBitSize option is also there to allow users to set a
system-wide default.
I added a release notes entry that described what has changed and also
included a few notes for module developers using this module, as the
first usage already popped up in NixOS/nixpkgs#39507.
Thanks to @Ekleog and @abbradar for reviewing.
Always enable both tty and serial console, but set preferred console
depending on cfg.graphical.
Even in qemu graphical mode, you can switch to the serial console via
Ctrl+Alt+3.
With that being done, you also don't need to specify
`systemd.services."serial-getty@ttyS0".enable = true;` either as described in
https://nixos.wiki/wiki/Cheatsheet#Building_a_service_as_a_VM_.28for_testing.29,
as systemd automatically spawns a getty on consoles passwd via cmdline.
This also means, vms built by 'nixos-rebuild build-vm' can simply be run
properly in nographic mode by appending `-nographic` to `result/bin/run-*-vm`,
without the need to explicitly add platform-specific QEMU_KERNEL_PARAMS.
This allows to set the default bit size for all the Diffie-Hellman
parameters defined in security.dhparams.params and it's particularly
useful so that we can set it to a very low value in tests (so it doesn't
take ages to generate).
Regardless for the use in testing, this also has an impact in production
systems if the owner wants to set all of them to a different size than
2048, they don't need to set it individually for every params that are
set.
I've added a subtest to the "dhparams" NixOS test to ensure this is
working properly.

When trying to run NSD to serve the root zone, one gets the following
error message:
error: illegal name: '.'
This is because the name of the zone is used as the derivation name for
building the zone file. However, Nix doesn't allow derivation names
starting with a period.
So whenever the zone is "." now, the file name generated is "root"
instead of ".".
I also added an assertion that makes sure the user sets
services.nsd.rootServer, otherwise NSD will fail at runtime because it
prevents serving the root zone without an explicit compile-time option.
Tested this by adding a root zone to the "nsd" NixOS VM test.

Without fcrontab being setuid, every attempt by an user in the fcron

following error:

```
Adding setuid by hand has resolved this issue and aligns with the way
fcrontab is installed on other distributions.
lib.optional returns a singleton or an empty list. Therefore the
argument does not need to be wrapped in a list.
An alternative patch could have used lib.optionals but seems like no
more elements are going to be added to the optional list.

Leaving it unspecified caused gdm-wayland to crash on boot, see #39615.
The change made other display managers not quit plymouth properly however. By
removing "multi-user.target" from `plymouth-quit.after` this is resolved.
The following changes have been applied:
- the property `http.headers.X-Content-Type-Options` must a list of
strings rather than a serialized list
- instead of `/etc/docker/registry/config.yml` the configuration will be
written with `pkgs.writeText` and the store path will be used to run
the registry. This reduces the risk of possible impurities by relying
on the Nix store only.
- cleaned up the property paths to easy readability and reduce the
verbosity.
- enhanced the testcase to ensure that digests can be deleted as well
- the `services.docker-registry.extraConfig` object will be merged with
`registryConfig`

The ability to specify "-drive if=scsi" has been removed in QEMU version
2.12 (introduced in 3e3b39f173).
Quote from https://wiki.qemu.org/ChangeLog/2.12#Incompatible_changes:
> The deprecated way of configuring SCSI devices with "-drive if=scsi"
> on x86 has been removed. Use an appropriate SCSI controller together
> "-device scsi-hd" or "-device scsi-cd" and a corresponding "-blockdev"

So whenever the diskInterface is "scsi" we use the new way to specify
the drive and fall back to the deprecated way for the time being. The
reason why I'm not using the new way for "virtio" and "ide" as well is
because there is no simple generic way anymore to specify these.
This also turns the type of the virtualisation.qemu.diskInterface option
to be an enum, so the user knows which values are allowed but we can
also make sure the right value is provided to prevent typos.
I've tested this against a few non-disk-related NixOS VM tests but also
the installer.grub1 test (because it uses "ide" as its drive interface),
the installer.simple test (just to be sure it still works with
"virtio") and all the tests in nixos/tests/boot.nix.
In order to be able to run the grub1 test I had to go back to
8b1cf100cd (which is a known commit where
that test still works) and apply the QEMU update and this very commit,
because right now the test is broken.
Apart from the tests here in nixpkgs, I also ran another[1] test in
another repository which uses the "scsi" disk interface as well (in
comparison to most of the installer tests, this one actually failed
prior to this commit).
All of them now succeed.

Previously the script would contain an empty `if` block (which is invalid
syntax) if both `data.activationDelay == null` and `data.postRun == ""`. Fix
this by adding a no-op `true`.
As suggested in https://github.com/NixOS/nixpkgs/pull/39416#discussion_r183845745
the versioning attributes in `lib` should be consistent to
`nixos/version` which implicates the following changes:
* `lib.trivial.version` -> `lib.trivial.release`
* `lib.trivial.suffix` -> `lib.trivial.versionSuffix`
* `lib.nixpkgsVersion` -> `lib.version`
As `lib.nixpkgsVersion` is referenced several times in `NixOS/nixpkgs`,
`NixOS/nix` and probably several user's setups. As the rename will cause
a notable impact it's better to keep `lib.nixpkgsVersion` as alias with
a warning yielded by `builtins.trace`.
mke2fs has this annoying property that it uses getrandom() to get random
numbers (for whatever purposes) which blocks until the kernel's secure
RNG has sufficient entropy, which it usually doesn't in the early boot
(except if your CPU supports RDRAND) where we may need to create the
root disk.
So let's give the VM a virtio RNG to avoid the boot getting stuck at
mke2fs.
Ubiquiti has both a LTS and current version of their Unifi controller software.
The latter adds new features, but may drop support for some devices.
This adds the capability to use either for the unifi module but defaults

Previously we indirectly suggested that the user use
services.printing.extraConf to set this, but this doesn't work with the
default merge ordering. Fix this by making it an independent option.

quotes in the same line:
$ find -name '*.nix' -exec sed -n -e '/=$/ { n; /'\'\''/p }' {} + | wc -l
817
$ find -name '*.nix' -exec grep "= *'' *\$" {} + | wc -l
14818
The next point is to get the type, default and example attributes on top
of the description because that's the way it's rendered in the manual.
Most services have their enable option close to the beginning of the
file, so let's move it to the top.
Also, I found the script attribute for dhparams-init.service a bit hard
to read as it was using string concatenation to split a "for" loop.
Now for the more substantial clean ups rather than just code style:
* Remove the "with lib;" at the beginning of the module, because it
makes it easier to do a quick check with "nix-instantiate --parse".
* Use ConditionPathExists instead of test -e for checking whether we
need to generate the dhparams file. This avoids spawning a shell if
the file exists already and it's probably more common that it will
exist, except for the initial creation of course.
* When cleaning up old dhparams file, use RemainAfterExit so that the
unit won't be triggered again whenever we stop and start a service
depending on it.
* Capitalize systemd unit descriptions to be more in par with most
other unit descriptions (also see 0c5e837b66).
* Use "=" instead of "==" for conditionals using []. It's just a very
small nitpick though and it will only fail for POSIX shells. Bash on
the other side accepts it anyway.

This option allows us to turn off stateful generation of Diffie-Hellman
parameters, which in some way is still stateful as the generated DH
params file is non-deterministic.
However what we can avoid with this is to have an increased surface for
failures during system startup, because generation of the parameters is
done during build-time.
Another advantage of this is that we no longer need to take care of
cleaning up the files that are no longer used and in my humble opinion I
would have preferred that #11505 (which puts the dhparams in the Nix
store) would have been merged instead of #22634 (which we have now).
Luckily we can still change that and this change gives the user the
option to put the dhparams into the Nix store.
Beside of the more obvious advantages pointed out here, this also
effects test runtime if more services are starting to use this (for
example see #39507 and #39288), because generating DH params could take
a long time depending on the bit size which adds up to test runtime.
If we generate the DH params in a separate derivation, subsequent test
runs won't need to wait for DH params generation during bootup.
Of course, tests could still mock this by force-disabling the service
and adding a service or activation script that places pre-generated DH
params in /var/lib/dhparams but this would make tests less readable and
the workaround would have to be made for each test affected.
Note that the 'stateful' option is still true by default so that we are
backwards-compatible with existing systems.

We're going to implement an option which allows us to turn off stateful
handling of Diffie-Hellman parameter files by putting them into the Nix
store.
However, modules now might need a way to reference these files, so we
add a now path option to every param specified, which carries a
read-only value of the path where to find the corresponding DH params
file.
I've also improved the description of security.dhparams.params a bit so
that it uses <warning/> and <note/>.
The NixOS VM test also reflects this change and checks whether the old
way to specify the bit size still works.

Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

* checks using package providing the nix-daemon that we'll be using
* made optional (unlike some other config checks) "just in case":
since this requires running the new Nix on the builder, this
won't work in a few (AFAIK very uncommon) situations such as
cross-compiling NixOS or using `include` directives in nix.conf
This does rely on Nix2 but not by the builder.
Since we only offer Nix2+ in-tree this should be fine,
and may otherwise be required anyway.
I know that "devinfo" output does not currently exist, but so does "devman".
It is mentioned in the nixpkgs manual, but no derivation in nixpkgs actually uses it.
HA doesn't mind the configuration being JSON instead of YAML but since YAML is
the official language, use that as it allows users to easily exchange config
data with other parties in the community.
Additionally, some settings based on NixOS configuation is set via defaultConfig
which is then merged with the user provided configration.
For now that just means http port and time zone but others can easily be added.
This partially reverts a change from e88f28965a
which removed the `mount --rbind /sys`.
While true that the activation scripts will mount `sysfs` at `/sys`,
none of the mountpoints lower in the `/sys` tree are handled by the
activation script, which includes `efivarfs`.
This fixes#38477 since it ensures the presence of `efivarfs` in the
`/sys` tree, which is why the systemd-boot installation failed.
This is more in line with what other services do; also looks cleaner.
It changes configuration entries for pre-and post-hooks type to lines from
lists of strings which are more logical for them; coersion is provided for
backwards compatibility.
Finally, add several steps to improve robustness:
1. Load kernel module on start if not loaded;
2. Don't remove wireguard interface on start; it is removed on service stop. If
it's not something is wrong.
This is needed because simp_le expects two certificates in fullchain.pem, leading to error:
> Not enough PEM encoded messages were found in fullchain.pem; at least 2 were expected, found 1.
We now create a CA and sign the key with it instead, providing correct fullchain.pem.
Also cleanup service a bit -- use PATH and a private temporary directory (which
is more suitable).
Do cleanup of user-created additional rules.
Of course it'd be much better to just use iptables-{save,restore} for
declarative management, but as it's still not there...
Introduced in 286b007bd3 and then
in 2e6b796761.
This a proper fix for what 70c6f6572d tried to do.
Removing the "config" prefix triggers the bug on pure nixos too, not only
on nixops.
Nothing probably uses this, but let's be pedantic and have the
pre-included channel on the install media be as close as possible to
what 'nix-channel --update' will give them.
The only remaining difference is that the channel adds programs.sqlite,
which is fundamentally unfixable.
a) Some providers can update multiple domains - support that.
b) Make "zone" and "script" configurable. Some providers require these.
c) Instead of leaving the ddclient daemon running all the time, use a systemd
timer to kick it off.
d) Don't use a predefined user - run everything via DynamicUser
e) Add documentation
Because it improves out-of-the-box user experience a lot (IMHO).
(zsh completion is already on by default.)
Remove "programs.bash.enableCompletion = true" from
nixos-generate-config.pl, which feels superflous now.
