Restarting them is useless since the filesystem is already
checked. Worse, restarting them causes the filesystem to be unmounted.
Also remove an override for systemd-rkill@.service which no longer
exists.
This reduces the time window during which IP addresses are gone during
switch-to-configuration. A complication is that with stopIfChanged =
true, preStop would try to delete the *new* IP addresses rather than
the old one (since the preStop script now runs after the switch to the
new configuration). So we now record the actually configured addresses
in /run/nixos/network/addresses/<interface>. This is more robust in
any case.

Unfortunately, somewhere between 16.09 and 17.03, paravirtualized
instances stopped working. They hang at the pv-grub prompt
("grubdom>"). I tried reverting to a 4.4 kernel, reverting kernel
compression from xz to bzip2 (even though pv-grub is supposed to
support xz), and reverting the only change to initrd generation
(5a8147479e). Nothing worked so I'm
giving up.
Docker socket is world writable. This means any user on the system is
able to invoke docker command. (Which is equal to having a root access
to the machine.)
This commit makes socket group-writable and owned by docker group.

Commit 75f131da02 added
`chown 'nginx:nginx' '/var/lib/acme'` to the pre-start script,
but since it doesn't use `chown -R`, it is possible that there
are older existing subdirs (like `acme-challenge`)
that are owned to `root` from before that commit went it.
AFAICT, this issue only occurs when sshd is socket-activated. It turns
out that the preStart script's stdout and stderr are connected to the
socket, not just the main command's. So explicitly connect stderr to
the journal and redirect stdout to stderr.
This reverts commit 1a74eedd07. It
breaks NixOps, which expects that
rm -f /etc/ssh/ssh_host_ed25519_key*

cat /etc/ssh/ssh_host_ed25519_key.pub
works.
When a user or group is revived, this allows it to be allocated the
UID/GID it had before.
A consequence is that UIDs and GIDs are no longer reused.

In order to use qt5ct (Qt5 Configuration Tool) to configure Qt5
settings (theme, font, icons, etc.) under DE/WM without Qt

set to "qt5ct".
It can be done automatically by this module, or by setting the
variable explicitly in the user or in the system configuration.

Having fixed the Google Compute Engine image build process's copying
of store paths in PR #24264, I ran `nixos-rebuild --upgrade switch`...
and the GCE image broke again, because it sets the NixOS configuration
option for the sysctl variable `kernel.yama.ptrace_scope` to
`mkDefault "1"`, i.e., with override priority 1000, and now the
`sysctl` module sets the same option to `mkDefault "0"` (this was
changed in commit 86721a5f78).
This patch raises the override priority of the Google Compute Engine
image configuration's definition of the Yama sysctl option to 500
(still lower than the priority of an unmodified option definition).
I have tested that this patch allows the Google Compute Engine image
to again build successfully for me.
And adopt the tests to add an interface and remove it again.
It should work when deactivating rstp, it will not work when activating

Currently, if you try to build a NixOS config including channel.nix, e.g.:
nix-build -I nixpkgs=. -I nixos-config=nixos/modules/installer/cd-dvd/installation-cd-minimal.nix nixos -A config.system.build.isoImage
twice in a row, you end up with two different build results. This is
caused by the 'result' symlink of the first build affecting the channel
contents of the second build.
If we use filterSource with a predicate that ignores the 'result'
symlinks, the problem is gone. Do the same thing for VIM/Emacs
swap/backup files to avoid even more 'spurious' rebuilds.
Additionally, filter out the '.git' directory at the same time, as we
'rm -rf' it from the result anyway. This avoids a considerable amount of
unnecessary file I/O copying and deleting the .git directory.
In `nixos/modules/virtualisation/google-compute-image.nix`, copy store
paths with `rsync -a` rather than `cp -prd`, because `rsync` seems
better able to handle the hard-links that may be present in the store,
whereas `cp` may fail to copy them.
I have tested that the Google Compute Engine image builds successfully
for me with this patch, whereas it did not without this patch.
This is the same fix applied for Azure images in commit

The inability to run strace or gdb is the kind of

This restriction can be re-enabled by setting

kimpanel does not show installed IBus engines or allow switching input
methods. kimpanel does show configured keyboard layouts through kxkb, so I
believe there is some problem communicating with IBus. No error messages are
produced in the log and I have been unable to discover the cause. I have no
intention of continuing to work on kimpanel at this time, so it should be
disabled. The GTK+ 3-based panel provided by IBus is perfectly serviceable in
the interim.
In the absence of XCURSOR_PATH, the function XcursorLibraryPath
in libXcursor will return a hardcoded value unsuitable for NixOS.
Some desktops as well as display managers in NixOS currently do
set XCURSOR_PATH, but there are combinations where neither does
(e.g. SDDM+XFCE), resulting in no cursor themes being available.
The new definition if XCURSOR_PATH is effectively the same as what
KDE's startkde currently does.

* The module uses `stringSplit` but it should be `splitString`
* `rmilter` doesn't actually support binding to multiple sockets.
Therefore, bind to the last one specified if `socketActivation` is
`false`.
I also believe there is a bug in this module related to systemd
`ListenStream`. If `socketActivation` is true, Postfix gets
connection timeouts trying to connect to one of the `ListenStream`
inet addresses. I don't know enough about `ListenStream` passing
connections on to `fd:3` to understand what's going on.
These changes are in production (with `socketActivation = false`) via NixOps.
This `tsocks` wrapper leaks DNS requests to clearnet, meanwhile Tor comes with

This option was initially added to make it easier to use an

From now on, you can either use a resolver listed by dnscrypt
upstream or a custom resolver.
Removes tcpOnly and ephemeralKeys: reifying them as nixos

Unless reifying an option is necessary for conditional

misconfiguration, it should go into extraArgs instead.

The Infinality bytecode interpreter is removed in favor of the new v40 TrueType
interpreter. In the past, the Infinality interpreter provided support for
ClearType-style hinting instructions while the default interpreter (then v35)
provided support only for original TrueType-style instructions. The v40
interpreter corrects this deficiency, so the Infinality interpreter is no longer
necessary.
To understand why the Infinality interpreter is no longer necessary, we should
understand how ClearType differs from TrueType and how the v40 interpreter
works. The following is a summary of information available on the FreeType
website [1] mixed with my own editorializing.
TrueType instructions use horizontal and vertical hints to improve glyph
rendering. Before TrueType, fonts were only vertically hinted; horizontal hints
improved rendering by snapping stems to pixel boundaries. Horizontal hinting is
a risk because it can significantly distort glyph shapes and kerning. Extensive
testing at different resolutions is needed to perfect the TrueType
hints. Microsoft invested significant effort to do this with its "Core fonts for
the Web" project, but few other typefaces have seen this level of attention.
With the advent of subpixel rendering, the effective horizontal resolution of
most displays increased significantly. ClearType eschews horizontal hinting in
favor of horizontal supersampling. Most fonts are designed for the Microsoft
bytecode interpreter, which implements a compatibility mode with
TrueType-style (horizontal and vertical) instructions. However, applying the
full horizontal hints to subpixel-rendered fonts leads to color fringes and
inconsistent stem widths. The Infinality interpreter implements several
techniques to mitigate these problems, going so far as to embed font- and
glyph-specific hacks in the interpreter. On the other hand, the v40 interpreter
ignores the horizontal hinting instructions so that glyphs render as they are
intended to on the Microsoft interpreter. Without the horizontal hints, the
problems of glyph and kerning distortion, color fringes, and inconsistent stem
widths--the problems the Infinality interpreter was created to solve--simply
don't occur in the first place.
There are also security concerns which motivate removing the Infinality patches.
Although there is an updated version of the Infinality interpreter for FreeType
2.7, the lack of a consistent upstream maintainer is a security concern. The
interpreter is a Turing-complete virtual machine which has had security
vulnerabilities in the past. While the default interpreter is used in billions
of devices and is maintained by an active developer, the Infinality interpreter
is neither scrutinized nor maintained. We will probably never know if there are
defects in the Infinality interpreter, and if they were discovered they would
likely never be fixed. I do not think that is an acceptable situtation for a
core library like FreeType.
Dropping the Infinality patches means that font rendering will be less
customizable. I think this is an acceptable trade-off. The Infinality
interpreter made many compromises to mitigate the problems with horizontal
hinting; the main purpose of customization is to tailor these compromises to the
user's preferences. The new interpreter does not have to make these compromises
because it renders fonts as their designers intended, so this level of
customization is not necessary.
The Infinality-associated patches are also removed from cairo. These patches
only set the default rendering options in case they aren't set though
Fontconfig. On NixOS, the rendering options are always set in Fontconfig, so
these patches never actually did anything for us!
The Fontconfig test suite is patched to account for a quirk in the way PCF fonts
are named.
The fontconfig option `hintstyle` is no longer configurable in NixOS. This
option selects the TrueType interpreter; the v40 interpreter is `hintslight` and
the older v35 interpreter is `hintmedium` or `hintfull` (which have actually
always been the same thing). The setting may still be changed through the
`localConf` option or by creating a user Fontconfig file.
Users with HiDPI displays should probably disable hinting and antialiasing: at
best they have no visible effect.
The fontconfig-ultimate settings are still available in NixOS, but they are no
longer the default. They still work, but their main purpose is to set rendering
quirks which are no longer necessary and may actually be
detrimental (e.g. setting `hintfull` for some fonts). Also, the vast array of
font substitutions provided is not an appropriate default; the default setting
should be to give the user the font they asked for.

Newer versions of DNSCrypt proxy *can* cache lookups (via

The nixbld group belongs to nix-daemon and you really don't want to be
in it. If you are in it, nix-daemon will kill your processes when you
least expect it :)
It'd be better to do the update as an unprivileged user; for
now, we do our best to minimize the surface available. We
filter mount syscalls to prevent the process from undoing the fs
isolation.
Resolve download.dnscrypt.org using hostip with a bootstrap
resolver (hard-coded to Google Public DNS for now), to ensure
that we can get an up-to-date resolver list without working name
service lookups. This makes us more robust to the upstream
resolver list getting out of date and other DNS configuration
problems.
We use the curl --resolver switch to allow https cert validation
(we'd need to do --insecure if using just the ip addr). Note
that we don't rely on https for security but it's nice to have
it ...
Use mkMerge to make the code a little more ergonomic and easier

After the change of the bonding options, the examples were not quite correct.

* "permanent": use the permanent MAC address of the device.
* "preserve": don’t change the MAC address of the device upon activation.
* "random": generate a randomized value upon each connect.
* "stable": generate a stable, hashed MAC address.

Version 2.0.0 is installed as a separate package called "couchdb2".
When setting the config option "package" attribute to pkgs.couchdb2, a
corresponding service configuration will be generated. If a previous
1.6 installation exists, the databases can still be found on the local
port (default: 5986) and can be replicated from there.
Note that single-node or cluster setup still needs to be configured
manually, as described in
http://docs.couchdb.org/en/2.0.0/install/index.html.
We only care about /nix/store because its contents might be out of
sync with /nix/var/nix/db. Syncing other filesystems might cause
unnecessary delays or hangs (e.g. I encountered a case where an NFS
mount was taking a very long time to sync).
The implicit behavior of pulling it out of the classpath seemed not
to work properly and could be thrown off by other things on the
classpath also providing the properties file. This guarantees that
our settings stick.
We now make it happen later in the boot process so that multi-user
has already activated, so as to not run afoul of the logic in
switch-to-configuration.pl. It's not my favorite solution, but at
least it works. Also added a check to the VM test to catch the failure
so we don't break in future.

phpfpm currently uses `readFile` to read the php.ini file from the
phpPackage. This causes php to be build at evaluation time.
This eliminates the use of readFile and builds the php.ini at build
time.
This reverts commit 29caa185a7.
Not clear what the proper thing to do is. cf94cdb59b renders this
question mostly moot. Reverting before 17.03 branch to avoid a repeat
of #19054.
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
This PR adds support for ```iio-sensor-proxy``` used by GNOME v3 and
others for reading data from the accelerometer, gps, compass and similar sensors
built into some relatively recent laptops.
Additionally, there is a NixOS module exposed via hardware.sensor.iio
for enabling services, udev rules and dbus services.
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
Using toJSON on a string value works because the allowed JSON escape
sequences is almost a subset of the systemd allowed escape sequences.
The only exception is `\/` which JSON allows but systemd doesn't.
Luckily this sequence isn't required and toJSON don't produce it making
the result valid for systemd consumption.
Examples of things that this fixes are environment variables with double
quotes or newlines.
Since systemd version 232 the install subcommand of bootctl opens the
loader.conf with fopen() modes "wxe", where the "e" stands for
exclusive, so the call will fail if the file exists.
For installing the boot loader just once this is fine, but if we're
using NIXOS_INSTALL_BOOTLOADER on a systemd where the bootloader is
already present this will fail.
Exactly this is done within the simpleUefiGummiboot installer test,
where nixos-install is called twice and thus the bootloader is also
installed twice, resulting in an error during the fopen call:
Failed to open loader.conf for writing: File exists
Removing the file prior to calling bootctl should fix this.
I've tested this using the installer.simpleUefiGummiboot test and it now
succeeds.

This leads to the following error when trying to install a new machine
where the machine ID wasn't yet initialized during boot:
Failed to get machine did: No such file or directory
In addition this was also detected by the simpleUefiGummiboot installer
test.
So let's generate a fallback machine ID by using
systemd-machine-id-setup before actually running bootctl.
Tested this by running the installer.simpleUefiGummiboot test, it still
fails but not because of the machine ID.

This is deliberate because using the taskd binary to configure
Taskserver has a good chance of messing up permissions.

there really is no need anymore to expose the taskd binary.
If people still want to use the taskd binary at their own risk they can
still add taskserver to systemPackages themselves.

Putting an include directive in the configuration file referencing a
store path with the real configuration file has the disavantage that
once we change the real configuration file the store path is also a
different one.
So we would have to replace that include directive with the new
configuration file, which is very much error-prone, because whenever
taskd modifies the configuration file on its own it generates a new one
with *only* the key/value options and without any include directives.
Another problem is that we only added the include directive on the first
initalization, so whenever there is *any* configuration change, it won't
affect anything.
We're now passing all the configuration options via command line,
because taskd treats everything in the form of --<name>=<value> to be a
configuration directive.
This also has the effect that we now no longer have extraConfig, because
configuration isn't a file anymore.
Instead we now have an attribute set that is mapped down to
configuration options.
Unfortunately this isn't so easy with the way taskd is configured,
because there is an option called "server" and also other options like
"server.cert", "server.key" and so on, which do not map very well to
attribute sets.
So we have an exception for the "server" option, which is now called
"server.listen", because it specifies the listening address.

The helper tool so far was only intended for use in automatic PKI
handling, but it also is very useful if you have an existing CA.
One of the main advantages is that you don't need to specify the data
directory anymore and the right permissions are also handled as well.
Another advantage is that we now have an uniform management tool for
both automatic and manual config, so the documentation in the NixOS
manual now applies to the manual PKI config as well.

reason: after the upgrade of iputils from 20151218 to 20161105
functionality of ping6 and tracepath6 was merged into ping and tracepath.
Ping is now mostly a drop-in replacment for ping6, except that selecting a

rather then specifing it with the `-I` flag.
To be able to use Wireshark as an ordinary user, the 'dumpcap' program
must be installed setuid root. This module module simplifies such a
configuration to simply:
programs.wireshark.enable = true;
The setuid wrapper is available for users in the 'wireshark' group.
Changes v1 -> v2:
- add "defaultText" to the programs.wireshark.package option (AFAIK,
that prevents the manual from being needlessly rebuilt when the
package changes)
Since the bonds interface changed to a lot more possible values we create a
mapping of kernel bond attribute names and values to networkd attributes.
Those match for the most part, but have to transformed slightly.
There is also an assert that unknown options won’t slip through silently.
Until now the four attributes available very selectively provided a small
subset, while copying upstream documentation.
We make driver options an arbitrary key-value set and point to kernel
documentation, which is always up-to-date. This way every option can be set.
The four already existing options are deprecated with a warning.
The initialization code is now a systemd service that explicitly
waits for network-online, so the occasional failure I was seeing
because the `nixos-rebuild` couldn't get anything from the binary
cache should stop. I hope!
* The source attribute is mandatory, not optional
* The program attribute is optional
* Move the info about the mandatory attribute first (most important,
IMHO)
Previously, netdev units for network interfaces defined in the nixos
configurations would bindTo the systemd device unit of the interface if
not in a container.
In situations where you switch to a new nixos configration with changes
to network-setup.service (like nameservers) and have stacked interfaces
like vlans on a bond, it would fail to propagate restarts to the netdevs
correctly resulting with broken networking. The bond would be present
but no vlan interfaces rendering the machine unreachable.
My fear is that the udev events fail to propagate correctly while a systemd
transaction that is also restarting the triggered netdev service is running.
This commit changes this behaviour so netdev services bindTo other netdev
services if present and otherwise fall back to the previous behaviour.
We also noticed that stacked interfaces would sometimes seemingly be stopped
in the wrong order. For instance in the above example, the bond interface
would be deleted before the vlan interfaces resulting in the vlan interfaces
not being present when their service is being stopped. This would cause the
systemd transaction to fail and thus break networking. Their postStop hooks
are now allowed to fail as we have reached the desired state.

Recent pvgrub (from Grub built with “--with-platform=xen”) understands
the Grub2 configuration format. Grub legacy configuration (menu.lst) is
ignored.
The GeoIP databases from MaxMind have no stable URLs and change every
month (or so). Our current method of packaging these database in Nix and
playing catch-up with ever-changing file hashes is a bad idea. For
instance, it makes it impossible to realize old NixOS configurations.
This patch adds a NixOS service that periodically updates the GeoIP
databases in /var/lib/geoip-databases. Moving NixOS modules over can be
done in later patches.
I tried adding MD5 check, but not all databases have them, so i skipped
it. We are downloading over HTTPS though, it should be good. I also
tried adding zip support, but the first zip file I extracted had a
different filename inside than the archive name, which breaks an
assumption in this service, so I skipped that too.
Changes v9 -> v10:
- Pass "--max-time" to curl to set upper bound on downloads (ensures
no indefinite hanging if there's problem with networking).
Timeout for network connectivity check: 60s.
Timeout for geoip database (each): 15m.
Changes v8 -> v9:
- Mention the random timer delay in the documentation for the
'interval' option.
Changes v7 -> v8:
- Add "RemainAfterExit=true" for the setup service, so it won't be
restarted needlessly. (Thanks @danbst!)
Changes v6 -> v7:
- Add --skip-existing flag to geoip-updater, which skips updating
existing database files. Pass that flag when we run the service on
boot (and on any NixOS configuration change).
(IMHO, this is somewhat a workaround for systemd persistent timers
not being triggered immediately when a timer has never expired
before. But it does have the nice side effect of ensuring that the
installed databases always correspond to the configured ones, since
the service is now always run after configuration changes.)
Changes v5 -> v6:
- Update database files atomically (per DB)
- If a database is removed from the configuration, it'll be removed
from /var/lib/geoip-databases too (on next run).
- Add NixOS module assertion so that if user inputs non- .gz or .xz
file there will be a build time error instead of runtime.
- Run updater as user "nobody" instead of "root".
- Rename NixOS service from "geoip-databases" to "geoip-updater".
- Drop RemainAfterExit, or else the timer won't trigger the unit.
- Bring back "curl --fail", or else we won't catch and log curl
failures.
Changes v4 -> v5:
- Add "GeoLite2-City.mmdb.gz" to default database list.
Changes v3 -> v4:
- Remove unneeded geoip-updater-setup.service after adding
'wantedBy = [ "multi-user.target" ]' directly to
geoip-updater.service
- Drop unneeded "Service" name from service descriptions.
Changes v2 -> v3:
- Network may be down when starting from a cold boot, so try a few
times. Possibly, if using systemd-networkd, it'll pass on the first
try. But with default DHCP on NixOS, the service is started before
hostnames can be resolved and thus we need a few extra seconds.
- Add error handling and mark service as failed if fatal error.
- Add proper syslog log levels.
- Add RandomizedDelaySec=3600 to the timer to not put high load on the
MaxMind servers. Suggested by @Mic92.
- Set RemainAfterExit on geoip-updater.service instead of
geoip-updater-setup.service. (The latter is only a proxy that pulls
in the former service).

nixos/geoip-databases: add `databases` option and fix initial setup
There were two great issues when using this service:
- When you just enable service, databases aren't downloaded, they are
downloaded when timer triggers. Fixed this with automatic download on
first system activation.
- When there is no internet, updater outputs nothing to logs, which is
IMO misbehavior. Fixed this with removing `--fail` option, better be
explicit here.
The Raspberry Pi boot loader was deleting all xx-initrd text files
(which simply contain the path to the actual initrd files) just after
having created them. The code was actually trying to delete real,
obsolete initrd files, which are named <hash>-initrd-initrd (after path
cleaning), but the glob was catching the other files as well.
Turns out all variants of start.elf and fixup.dat are needed (depending
on what's in config.txt). I was under the mistaken impression that you
were supposed to rename one of the variants to switch using them, but
nope.
A very simple skeleton for now that doesn't attempt to model any of
the agent configuration, but we can grow it later. Tested and works
on an EC2 instance with ECS.
Recent versions of libreswan seem to omit this file, but it may be added/changed in the future. It is silly to have the service fail because a file is missing that only enriches the environment.
