- Fully get rid of `parseKeyValues` and use systemctl features for that
- Add some regex modifiers recommended by perlcritic
- Get rid of a postfix if
- Sort units when showing their status
- Clean the logic for showing what failed from `elif` to `next`
- Switch from `state` to `substate` for `auto-restart` because that's
actually where the value is stored
- Show status of units with one single systemctl call and get rid of
COLUMNS in favor of --full
- Add a test for failing units
This replaces the naive K=V unit parser with a proper INI parser from a
library and adds proper support for override files. Also adds a bunch of
comments about parsing, I hope this makes it easier to understand and
maintain in the future.
There are multiple reasons to do so, the first one is just general
correctness with is nice imo. But to get to more serious reasons (I
didn't put in all that effort for nothing) is that this is the first
step torwards more clever restart/reload handling. By using a library
like Data::Compare a future PR could replace the current way of
fingerprinting units (which is to compare store paths) by comparing the
hashes. This is more precise because units won't get restarted because
the order of the options change, comments are added, some dependency of
writeText changes, .... Also this allows us to add a feature like
`X-Reload-Triggers` so the unit can either be reloaded when these change
or restarted when everything else changes, giving module authors the
ability to have their services reloaded without having to fear that
updates are not applied because the service doesn't get restarted.
Another reason why this feature is nice is that now that the unit files
are parsed correctly (and values are just extracted from one section),
potential future rewrites can just rely on some INI library without
having to implement their own weird parser that is compatible with this
script.
This also comes with a new subroutine to handle systemd booleans because
I thought the current way of handling it was just ugly. This also allows
overriding values this script reads in an override file.
Apart from making this script more compatible with the world around it,
this also fixes two issues I saw bugging exactly 0 (zero) people. First
is that this script now supports multiple override files, also ones that
are not called override.conf and the second one is that `1` and `on` are
treated as bools by systemd but were previously not parsed as such by
switch-to-configuration.
Update the example config to show a working example for xmonad 0.17.0, which
added an argument to the `launch` function and adjusted the location of the
recompiled binary.
Webclient only allows serving a web directory under /_matrix/client
This only incentivizes running the client under the same domain as the homeserver.
Which is not recommended due to CORS.
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.
This commit introduces a new option
`services.nextcloud.nginx.recommendedHttpHeaders` that can be used to
optionally disable serving recommended HTTP Response Headers in nginx.
This is especially useful if some headers are already configured
elsewhere to be served in nginx and thus result in duplicate headers.
Resolves#120223
The `extraConfig` parameter only handles text - it doesn't support
arbitrary secrets and, with the way it's processed in the setup
script, it's very easy to accidentally unescape the echoed string and
run shell commands / feed garbage to bash.
To fix this, implement a new option, `config`, which instead takes a
typed attribute set, generates the `.env` file in nix and does
arbitrary secret replacement. This option is then used to provide the
configuration for all other options which change the `.env` file.
When upgrading bookstack, if something in the cache conflicts with the
new installation, the artisan commands might fail. To solve this, make
the cache lifetime bound to the setup service. This also removes the
`cacheDir` option, since the path is now handled automatically by
systemd.
Commit 9a5b5d9fe8 added Haskell
dependencies (GHC and packages) to the xmonad binary's environment even
if xmonad had been preconfigured (via the "config" option). The intent
was to enable one-off recompiling using a local config file (e.g.
~/.config/xmonad/xmonad.hs), so the user can get quick feedback while
developing their config.
While this works, it may not be a common use-case, and it requires some
careful crafting in xmonad.hs itself. On top of that, it significantly
increases the size of the closure.
Given all that, commit b69d9d3c23 removed
GHC and packages from the binary's environment.
But there are still those among us who want to be able to recompile from
a preconfigured xmonad, so let's provide a way to opt-into configured
recompilation.
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.
This removes `/run/nixos/activation-reload-list` (which we will need in
the future when reworking the reload logic) and makes
`/run/nixos/activation-restart-list` honor `restartIfChanged` and
`reloadIfChanged`. This way activation scripts don't have to bother with
choosing between reloading and restarting.
Instead of referencing all library functions through `lib.` and
builtins through `builtins.` at every invocation, inherit them into
the appropriate scope.
The module option type `nonEmptyStr` was introduced in commit
a3c5f0cba8
The tsm modules previously simply used
`strMatching ".+"` to prevent empty option strings,
but the new type is more thorough as
it also catches space-only strings.
This enables some systemd sandboxing
options for the `tsm-backup.service`.
Those settings have been determined by expermentation.
This commit tries hard to protect the filesystem from
write access, but not to hide anything from read access,
so users can backup all files they choose to backup.
An exception are API filesystems (`/dev`, `/proc`, `/sys`):
As their "files" are not stored on persistent storage,
they are sandboxed away as much as possible.
Note that the service still has to run with root
privileges to reach files with limited access permissions.
The obvious alternative to use a dedicated user account and
the `CAP_DAC_READ_SEARCH` capability to permit system-wide
read access while blocking write access does not work.
Experiments have shown that `dsmc` verifies access permissions
for each file before attempting to open it for reading.
Hence `dsmc` refuses to copy files where the file permission
mode blocks read access -- even if process capabilities
would allow it to proceed irrespective of permissions.
Use systemd's LoadCredential mechanism to make the secret files
available to the service.
This gets rid of the privileged part of the ExecPreStart script which
only served to copy these files and assign the correct
permissions. There's been issues with this approach when used in
combination with DynamicUser, where sometimes the user isn't created
before the ExecPreStart script runs, causing the error
install: invalid user ‘keycloak’
This should fix that issue.
Unfortunately, all of the ExecPreStart script had to be moved to
ExecStart, since credentials aren't provided to ExecPreStart. See
https://github.com/systemd/systemd/issues/19604.
Without this option `DefaultSearchProviderSearchURL` and
`DefaultSearchProviderSuggestURL` are really wastefull as it does not
set search engine, at least for me.

This together with extraConfig:
{
"subsystem=undertow"."server=default-server"."http-listener=default"."proxy-address-forwarding" = true;
"subsystem=undertow"."server=default-server"."https-listener=https"."proxy-address-forwarding" = true;
}
Allows to run Keycloak behind a reverse proxy that provides
X-Forwarded-* headers.
Allow update commands in the script to be ordered using `mkOrder`.
If we encounter ordered sub-objects we sort them by priority.
To implement this we now explicitly pass current node in `recurse`,
which also allows us to clean up edge case for top-level node.
Also refactor `recurse` to avoid passing result text argument; we
weren't tail recursive before anyway.
Still actively developed and yet stuck on python2. Also marked as

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.
I was confused why I couldn't find a mention of udev.log_priority in
systemd-udevd.service(8). It turns out that it was renamed[1] to
udev.log_level. The old name is still accepted, but it'll avoid
further confusion if we use the new name in our documentation.

The programs.ssh.knownHosts.*.publicKeyFile is broken, because it's
scoped to a set of host names, but to insert those host names on each
line of the file we'd have to parse out blank lines and comments, so
only the first line works. It would be much easier all round if users
just provided known hosts files in the normal format, and we pointed
ssh directly to them. This way, it would be possible to have multiple
keys for a single host (which is extremely common due to multiple
algorithms being commonplace).
We add an option for this instead of relying on extraConfig, because
we need to make sure /etc/ssh/ssh_known_hosts is always included to
ensure programs.ssh.knownHosts keeps working.
/etc/ssh/ssh_known_hosts2 is another OpenSSH default that seems a bit
weird, but there's no real reason to change that so we'll leave it.
The Intel SGX DCAP driver makes the SGX application enclave device and
the SGX provisioning enclave available below the path `/dev/sgx/`. Since
Linux 5.11, a derivation of the DCAP driver is part of the kernel and
available through the X86_SGX config option; NixOS enables this option
by default.
In contrast to the out-of-tree DCAP driver, the in-tree SGX driver uses
a flat hierarchy for the SGX devices resulting in the paths
`/dev/sgx_enclave` for the application enclave device and
`/dev/sgx_provison` for the provisioning enclave device.
As of this commit, even the latest version of the Intel SGX PSW
libraries still tries to open the (legacy) DCAP paths only. This means
that SGX software currently cannot find the required SGX devices even if
the system actually supports SGX through the in-tree driver. Intel wants
to change this behavior in an upcoming release of intel/linux-sgx.
Having said that, SGX software assuming the SGX devices below
`/dev/sgx/` will prevail. Therefore, this commit introduces the NixOS
configuration option `hardware.cpu.intel.sgx.enableDcapCompat` which
creates the necessary symlinks to support existing SGX software. The
option defaults to true as it is currently the only way to support SGX
software. Also, enabling the SGX AESM service enables the option.
The permissions of the devices `/dev/sgx_enclave` and
`/dev/sgx_provison` remain the same, i.e., are not affected regardless
of having the new option enabled or not.
This option makes the complete netdata configuration directory available for
modification. The default configuration is merged with changes
defined in the configDir option.

During working on #150837 I discovered that `google-oslogin` test
started failing, and so did some of my development machines. Turns out
it was because nscd doesn't start by default; rather it's wanted by
NSS lookup targets, which are not always fired up.
To quote from section on systemd.special(7) on `nss-user-lookup.target`:
> All services which provide parts of the user/group database should be
> ordered before this target, and pull it in.
Following this advice and comparing our unit to official `sssd.service`
unit (which is a similar service), we now pull NSS lookup targets from
the service, while starting it with `multi-user.target`.
This renames our `firmwareLinuxNonfree` package to `linux-firmware`.
There is prior art for this in multiple other distros[1][2][3].
Besides making the package more discoverable by those searching for the
usual name, this also brings it in-line with the `kebab-case` we
normally see in `nixpkgs` pnames, and removes the `Nonfree` information
from the name, which I consider redundant given it's present in
`meta.license`.
The corresponding alias has been added, so this shouldn't break
anything.

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.
Previously we allocated subuids automatically for all normal users.
Make this explicitly configurable, so that one can use this for system
users too (or explicitly disable for normal users). Also don't allocate
automatically by default if a user already has ranges specified statically.
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.
a few things should've used buildPackages/nativeBuildInputs to not not require
the host architecture for building docs. tested by building aarch64-linux docs
on x86_64-linux, and the result looks good.
In https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/merge_requests/153
the user target names for GSD components has been renamed for example
from `gsd-a11y-settings.target` to `org.gnome.SettingsDaemon.A11ySettings.target`,
and nowadays `gsd-*.target` are just symbolic links of `/dev/null` and will be
removed in the future.
At the same time, as mentioned in d27212d466,
we are adding `systemd.user.targets.<name>.wants` stuff here only because
systemd.packages doesn't pick the .wants directories. Nowadays those GSD components
are managed in `/etc/systemd/user/gnome-session@gnome.target.d/gnome.session.conf`
so it should be safe to remove them.
In this commit we also try to pick up those new .wants directories, see also

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.
