3c74e48d9c was a bit too much, it updated
permissions of all files recursively, causing files to be readable by
the group.
This isn't a problem immediately after bootup, but on a new activation,
as tmpfiles.d get restarted then, updating the permission bits of
now-existing files.
This updates the `Z` to be a `z` (the non-recursive variant), and adds a
`d` to ensure a directory is created (which should be covered by the
initrd shell script anyway)
boot.specialFileSystems is used to describe mount points to be set up in
stage 1 and 2.
We use it to create /run/keys already there, so sshd-in-initrd scenarios
can consume keys sent over through nixops send-keys.
However, it seems the kernel only supports the gid=… option for tmpfs,
not ramfs, causing /run/keys to be owned by the root group, not keys
group.
This was/is worked around in nixops by running a chown root:keys
/run/keys whenever pushing keys [1], and as machines had to have pushed keys
to be usable, this was pretty much always the case.
This is causing regressions in setups not provisioned via nixops, that
still use /run/keys for secrets (through cloud provider startup scripts
for example), as suddenly being an owner of the "keys" group isn't
enough to access the folder.
This PR removes the defunct gid=… option in the mount script called in
stage 1 and 2, and introduces a tmpfiles rule which takes care of fixing
up permissions as part of sysinit.target (very early in systemd bootup,
so before regular services are started).
In case of nixops deployments, this doesn't change anything.
nixops-based deployments receiving secrets from nixops send-keys in
initrd will simply have the permissions already set once tmpfiles is
started.
Fixes #42344

We should wait until after `multi-user.target` is triggered to allow
hardware to finish initializing, such as network devices and USB drives.
This ensures `powertop --auto-tune` sets more tunables to "Good".
Fixes #66820
This commit moves all the virtual console related options
to a dedicated config/console.nix NixOS module.
Currently most of these are defined in config/i18n.nix
with a "console" prefix like `i18n.consoleFont`,
`i18n.consoleColors` or under `boot` and are implemented
in tasks/kbd.nix.
Since they have little to do with actual internationalisation
and are (informally) in an attrset already, it makes sense to
move them to a specific module.
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
Just maching all network interfaces caused many breakages, see #18962
and #71106.
We already don't support the global networking.useDHCP,
networking.defaultGateway(6) options if networking.useNetworkd is
enabled, but direct users to configure the per-device
networking.interfaces.<name?>.… options.
We don't want to ignore config that can mess up machines. In general
this should always fail evaluation, as you think you are changing
behaviour and don't, which can easily create run-time errors we can
catch early.
With systemd version 243 network units with empty match block will
generate warnigs. The reasoning seems to be that the intended behaviour
is hard to infere. Being explicit about really meaning any interface is
the reasonable thing here.
We want to get rid of this mechanism in the long run but as long as we
do not have a replacement we should stick with it and keep it in
reasonable good shape.
This fixes a serious bug on NixOS with swraid where mdadm arrays weren't
properly stopped on shutdown. Rather than fixing the unit by adding
`Before=final.target` we completely move to upstream units, which uses
systemd shutdown hooks instead. This also drives down maintenance costs
for us.
Introduces a trim timer similar to the fstrim service.
According to zpool(8) for consumer hardware periodic manual TRIM
is preferred over automatic TRIM that ZFS implements.
The period of one week is based on recommendations of fstrim.
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
Same as zfsUnstable for the moment.
We still keep the zfsUnstable expression as we likely
need it in the near future again.
Also remove spl since it is no longer needed.
With systemd v242 using the `Gateway` attribute of the `[Network]`
section will lead to "onlink" routes on all the device that are matched
by the default configuration (typically all devices) causing multiple
default routes (even on localhost).
We can only avoid that - while keeping our default route option - when
we mark the route as explicitly not on link. Only gateways that are
within a subnet of one of the assigned interface addresses will be
installed into the routing table.
Assert that autoResize is only used when fsType is explicitly set to a
supported filesystem: if it's set to "auto", the default, the required
resizing tools won't be copied into the initrd even if the actual
filesystem is supported.
27982b408e introduced a bug when
refactoring the encrypted-devices module, causing some encrypted
filesystem options to not be recognized anymore.
See e.g. https://hydra.nixos.org/build/88145490
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
When a bridge interface was reconfigured, running containers using
this bridge lost connectivity: restarting network-addresses-brN.service
triggered a restart of network-setup.service via a "partOf" relationship
introduced in 07e0c0e0a2.
This in turn restarted brN-netdev.service.
The bridge was thus destroyed and recreated with the same name but a new
interface id, causing attached veth interfaces to lose their connection.
This change removes the "partOf" relationship between
network-setup.service and network-addresses-brN.service for all bridges.
1. Simplify the command by reading directly from /etc/machine-id which
is already a random, lower-case hex string
2. Previously, the command output could be too short because of missing
leading digits. This is now fixed.
when the parent interface of a vlan interface is not up (yet), ip link cannot bring the vlan interface up
the vlan interface will be automatically brought up when the parent interface is up later
