Minor incompatibilities due to moving to upstream defaults:
- capabilities are used instead of systemd.socket units
- the control socket moved:
/run/kresd/control -> /run/knot-resolver/control/1
- cacheDir moved and isn't configurable anymore
- different user+group names, without static IDs
Thanks Mic92 for multiple ideas.
There is no need to stop/start the unit when the machine is online or
offline.
This should fix the shutdown locking issues.
nixos zerotier: sometimes it doesn't shutdown
Deperecates the interfaces option which was used to generate a host:port
list whereas the port was always hardcoded to 53. This unifies the
listen configuration for plain and TLS sockets and allows to specify a
port without an address for wildcard binds.
Systemd dependencies for scripted mode
were refactored according to analysis in #34586.
networking.vswitches can now be used with systemd-networkd,
although they are not supported by the daemon, a nixos receipe
creates the switch and attached required interfaces (just like
the scripted version).
Vlans and internal interfaces are implemented following the
template format i.e. each interface is
described using an attributeSet (vlan and type at the moment).
If vlan is present, then interface is added to the vswitch with
given tag (access mode). Type internal enabled vswitch to create
interfaces (see openvswitch docs).
Added configuration for configuring supported openFlow version on
the vswitch
This commit is a split from the original PR #35127.
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
As part of the networking.* name space cleanup, connman should be moved
to services.connman. The same will happen for example with
networkmanager in a separate PR.
The new description should give more clear understanding of when to
edit the option.
I used NixOS to set up a DNS server that is authoritative for certain
zones. The description of the `cacheNetworks` option made me think I
needed to set it to `"any"` to allow people to query the zone I set
up. Reading the source of the module would have clarified my
understanding, but at the time I just read the description and thought
little of it. Later I discovered I was getting tons of DNS requests
and presumably being used for a DNS amplification attack or similar.
I have fixed the problem now, but I would like the option to have a
clearer description so others don't make the same mistake I did.
Add a virtual user system based around pam and a Berkeley

Ever since setting up bonding the `wpa_supplicant-unit-start` script has
been failing. This is because the file `bonding_masters` in
`/sys/class/net/` is *not* a directory containing `uevent`.
Adding a test to verify the `uevent` path to be sourced exists resolves
the problem.
The two new options make it possible to create the interface in one namespace
and move it to a different one, as explained at https://www.wireguard.com/netns/.
In cases where you boot up really quickly (like in the VM test on a
non-busy host), tinydns might want to bind before the loopback interface
is fully up. Order tinydns after network.target to fix that.
Incorrect merging of modules resulted in dhcpcd being enabled causing flaky network connection.
https://github.com/NixOS/nixpkgs/pull/64364
Fixing it uncovered an infinite recursion from the same commit, previously masked by the incorrect merge.
We can just drop the `mkDefault` for `networking.wireless.enable` as it is already `false` by default.
Closes: https://github.com/NixOS/nixpkgs/issues/72416
This change ensures that `dhcpcd.service` is restarted as soon as the
exit hook changes. I use this hook to do additional configuration for my
network (like setting a route via the given gateway to my WireGuard) and
when changing parts of this exit hook I'd expect to get this activated
when switching to my new configuration.
This is a good example of a package/module that should be distributed
externally (e.g. as a flake [1]): it's not stable yet so anybody who
seriously wants to use it will want to use the upstream repo. Also,
it's highly specialized so NixOS is not really the right place at the
moment (every NixOS module slows down NixOS evaluation for everybody).

It seems that dnsdist doesn't actually request CAP_NET_BIND_SERVICE, which is why normally it's executed and root and setuids to another, unprivileged, user. This means that as it is, dnsdist will be unable to bind to any port under 1024 and will fail with access denied.
Removing CAP_SETGID and CAP_SETUID is also related to this as we don't actually change the uid or gid after the fact as we use DynamicUser. (That part isn't strictly NEEDED but there's no reason to have those capabilities if we don't use them).
There are also some additional sandboxing we can remove from the service definition as they are assumed true or strict by DynamicUser: specifically PrivateTmp and ProtectSystem respectively.
ProtectHome is still there, despite being assumed read-only as setting it to true means they are seen as empty. I don't think it really matters as I don't know if systemd will ignore it or not, but I didn't see any reason to go hunting for excuses to make it a bigger change.
This option was removed because allowing (multiple) regular users to
override host entries affecting the whole system opens up a huge attack
vector. There seem to be very rare cases where this might be useful.
Consider setting system-wide host entries using networking.hosts,
provide them via the DNS server in your network, or use
networking.networkmanager.appendNameservers to point your system to
another (local) nameserver to set those entries.
Otherwise connecting simply fails:

This fixes a regression from bb649d96b0.
There were permission problems, when the preStart script tried to copy

This introduces an option wifi.backend to the networkmanager module.

Resolves#66650
These are the leftovers of an older PR.
a. Send messages to auditd if auditing is enabled.
b. Add missing dbus configuration if dnsmasq is used for DNS
Fixes problems such as:
systemd[1]: Failed to put bus name to hashmap: File exists
systemd[1]: dbus-org.freedesktop.nm-dispatcher.service: Two services allocated for the same bus name org.freedesktop.nm_dispatcher, refusing operation.
Problem is that systemd treats symlinks to files outside the service
path differently, causing our old workaround to look like two separate services.
These symlinks are intended to be a means for manually emulating
the behavior of the `Alias=` directive in these services.
Unfortunately even making these symlinks relative isn't enough,
since they don't make it to where it matters--
that only makes the links in /etc/static/systemd/system/*
relative, with systemd still being shown non-relative links
in /etc/systemd/system/*.
To fix this, drop all of this at the package level
and instead simply specify the aliases in the NixOS modules.
Also handle the same for modemmanager,
since the networkmanager NixOS module also handles that.

This option was added in 6336048c58 but it
is essentially a complete duplicate of the existing cfg.servers and
there seems to be no reason to keep maintaining it.
Furthermore, it requires annoying duplication if you try to do option
merging, e.g. merging in sets into your configuration.nix that add
`services.chrony.initstepslew` options will overwrite the servers option
unless you keep it, but that means you just have to duplicate
config.networking.timeServers again anyway which is an implementation
detail!

'iburst' allows chrony to make very quick adjustments to the clock by
doing a couple rapid measurements outside of the default 'minpoll'
option. This helps improve rapid time adjustment at boot, and is enabled
by default.

Since https://github.com/NixOS/nixpkgs/pull/61321, local-fs.target is
part of sysinit.target again, meaning units without
DefaultDependencies=no will automatically depend on it, and the manual
set dependencies can be dropped.
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).
As described in the NixOps manual[1], dependencies to keys should be
defined like this now:
``` nix
{
systemd.services.myservice = {
after = [ "secret-key.service" ];
wants = [ "secret-key.service" ];
};
}
```
However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.

When NetworkManager is configured to not manage all interfaces, it's
perfectly fine to have the rest be managed by the standard nixos
wireless scripts.
I use
networking.networkmanager.unmanaged = [
"*" "except:type:wwan" "except:type:gsm"
];
to control everything using networking.wireless except for the mobile
LTE modem which only works with NetworkManager.
The following configuration generates a systemd unit that doesn't
start.
```nix
{
services.syncthing = {
enable = true;
user = "my-user";
};
}
```
It fails with
```
systemd[1]: Started Syncthing service.
systemd[6745]: syncthing.service: Failed to determine group credentials: No such process
systemd[6745]: syncthing.service: Failed at step GROUP spawning /nix/store/n1ydz3i08nqp1ajc50ycy1zribmphqc9-syncthing-1.1.4-bin/bin/syncthing: No such process
systemd[1]: syncthing.service: Main process exited, code=exited, status=216/GROUP
systemd[1]: syncthing.service: Failed with result 'exit-code'.
```
This is due to the fact that `syncthing` group (default) is not
created if the user is overridden.
Add a separate check for setting up the default group, so that
user/group are created independently.
