This change updates the instructions for building a NixOS ISO so that it's clear how to do it.
Previously, the instructions stated to set NIXOS_CONFIG prior to running `nix-build`, yet the example provided by-passed NIXOS_CONFIG anyway. But the *really* important missing piece is the need for nixos/default.nix. See #21840.
This change removes the NIXOS_CONFIG verbiage, and adds steps to clone nixpkgs and (most importantly) cd'ing into nixpkgs/nixos. That way, the reader may think: *Oh, so I need a default.nix and a configuration.nix. Ahhh, OK.*
I purposely added the redundant default.nix argument.
* postgresql service: make 9.6 the default version for 17.09
* postgresql service: change default superuser for 17.09
Change the default superuser from `root` to `postgres` for state
version 17.09
* postgresql service: change default data directory for 17.09
The new directory includes the schema version of the database.
This makes upgrades easier and is more consistent with other distros.
* updated nixos release notes
While systemd suggests using the pre-defined graphical-session user
target, I found that this interface is difficult to use. Additionally,
no other major distribution, even in their unstable versions, currently
use this mechanism.
The window or desktop manager is supposed to run in a systemd user service
which activates graphical-session.target and the user services that are
binding to this target. The issue is that we can't elegantly pass the
xsession environment to the window manager session, in particular
whereas the PassEnvironment option does work for DISPLAY, it for some
mysterious reason won't for PATH.
This commit implements a new graphical user target that works just like
default.target. Services which should be run in a graphical session just
need to declare wantedBy graphical.target. The graphical target will be
activated in the xsession before executing the window or display manager.
Fixes#17858.

An iso containing metadatas is created and attached as a cdrom to the
qemu VM used for this test.
The cloudinit service is enabled. The test case ensures the root
authorized_keys file is populated and the cloudinit write_file module is
working well.
OVMF{,CODE,VARS}.fd are now available in a dedicated fd output, greatly
reducing the closure in the common case where only those files are used (a
few MBs versus several hundred MBs for the full OVMF).
Note: it's unclear why `dontPatchELF` is now necessary for the build to
pass (on my end, at any rate) but it doesn't make much sense to run this
fixup anyway,
Note: my reading of xen's INSTALL suggests that --with-system-ovmf should
point directly to the OVMF binary. As such, the previous invocation was
incorrect (it pointed to the root of the OVMF tree). In any case, I have
only built xen with `--with-system-ovmf`, I have not tested it.

Without this change there will be silent errors when enabling screen
sharing. The GUI thinks it enables the service when it in fact does not
(errors are seen in the system journal).
vino is already in the closure of gnome-control-center, so this is
basically free.
Configuration of screen sharing is done in GNOME control center.
error now adds the zone file in the output which makes 'reasonable' debugging possible!

... because `nixos-generate-config` currently understand it's running under virtualbox, and correctly adds the configuration in `/etc/nixos/hardware-configuration.nix`
printer driver and wrapper are often not written with security in mind.
While reviewing https://github.com/NixOS/nixpkgs/pull/25654 I found
a symlink-race vulnerability within the wrapper code, when writing
unique files in /tmp.
I expect this script to be reused in other models as well
as similar vulnerabilities in the code of other vendors. Therefore
I propose to make /tmp of cups.service private so that only processes
with the same privileges are able to access these files.
Since fat32 provides little recovery facilities after a crash,
it can leave the system in an unbootable state, when a crash/outage
happens shortly after an update. To decrease the likelihood of this
event sync the efi filesystem after each update.
Due the recent inclusion of broadcom-bt-firmware in enableAllFirmware,
it was required to set `nixpkgs.config.allowUnfree` to obtain the full
list. To make this dependency more explicit an assertion is added and an
alternative option `enableRedistributalFirmware` is provided to only
obtain firmware with an license allowing redistribution.
IPFS uses the environment variable IPFS_PATH to determine where to look for it's data, which wasn't set previously therefore ignoring the dataDir attribute

/etc/dd-agent/conf.d is used.
Before NixOS 17.03, we were using dd-agent 5.5.X which
used configuration from /etc/dd-agent/conf.d
In NixOS 17.03 the default conf.d location is first used relative,
meaning that $out/agent/conf.d was used without NixOS overrides.
This change implements similar functionality as PR #25288, without
breaking backwards compatibility.
(cherry picked from commit 77c85b0ecbc1070d7adff31b339bede92e4193fa)
Provide the option forwardDns in virtualisation.xen.bridge, which
enables forwarding of DNS queries to the default resolver, allowing
outside internet access for the xen guests.
When you have a setup consisting of multiple monitors, the default is
that the first monitor detected by xrandr is set to the primary monitor.
However this may not be the monitor you need to be set as primary. In
fact this monitor set to primary may in fact be disconnected.
This has happened for the original submitter of the pull request and it
affected these programs:
* XMonad: Gets confused with Super + {w,e,r}
* SDDM: Puts the login screen on the wrong monitor, and does not
currently duplicate the login screen on all monitors
* XMobar: Puts the XMobar on the wrong monitor, as it only puts the
taskbar on the primary monitor
These changes should fix that not only by setting a primary monitor in
xrandrHeads but also make it possible to make a different monitor the
primary one.
The changes are also backwards-compatible.
This test exercises the linux_hardened kernel along with the various
hardening features (enabled via the hardened profile).
Move hidepid test from misc, so that misc can go back to testing a vanilla
configuration.
Adds an option `security.lockKernelModules` that, when enabled, disables
kernel module loading once the system reaches its normal operating state.
The rationale for this over simply setting the sysctl knob is to allow
some legitmate kernel module loading to occur; the naive solution breaks
too much to be useful.
The benefit to the user is to help ensure the integrity of the kernel
runtime: only code loaded as part of normal system initialization will be
available in the kernel for the duration of the boot session. This helps
prevent injection of malicious code or unexpected loading of legitimate
but normally unused modules that have exploitable bugs (e.g., DCCP use
after free CVE-2017-6074, n_hldc CVE-2017-2636, XFRM framework
CVE-2017-7184, L2TPv3 CVE-2016-10200).
From an aestethic point of view, enabling this option helps make the
configuration more "declarative".

Use a solid black background when no background image (via
~/.background-image) is provided. In my case this fixes the really
strange behaviour when i3 without a desktop manager starts with the SDDM
login screen as background image.
This eliminates a theoretical risk of ASLR bypass due to the fixed address
mapping used by the legacy vsyscall mechanism. Modern glibc use vdso(7)
instead so there is no loss of functionality, but some programs may fail
to run in this configuration. Programs that fail to run because vsyscall
has been disabled will be logged to dmesg.

The xsession script was called with inconsistent (depending on the
display managers) and wrong parameters. The main reason for this where
the spaces the parameter syntax. In order to fix this the old syntax:
$1 = '<desktop-manager> + <window-manager>'
Will be replaced with a new syntax:
$1 = "<desktop-manager>+<window-manager>"
This assumes that neither "<desktop-manager>" nor "<window-manager>"
contain the "+" character but this shouldn't be a problem.
This patch also fixes the quoting by using double quotes (") instead of
single quotes (') [0].
Last but not least this'll add some comments for the better
understanding of the script.

Upstream has decided to make -testing patches private, effectively ceasing
free support for grsecurity/PaX [1]. Consequently, we can no longer
responsibly support grsecurity on NixOS.
This patch turns the kernel and patch expressions into build errors and
adds a warning to the manual, but retains most of the infrastructure, in
an effort to make the transition smoother. For 17.09 all of it should
probably be pruned.

The xen-bridge service accepts the option prefixLength, but does not
use it to set the actual netmask on the bridge. This commit makes
it set the correct netmask.
Right now the `programs.zsh.syntax-highlighting.highlighters` option
lacks appropriate validation which can cause confusing things when
mistyping a higlighter for zsh-syntax-highlighting.
Someone on IRC wanted to boot Fedora from another disk. While I'm not
too familiar with UEFI booting in conjunction with GRUB2 it took some
time to get it to work.
So in order to safe others from frustration I'm adding this as another
example to the extraEntries option.

QEMU can allow guests to access more than one host core at a time.
Previously, this had to be done via ad-hoc arguments:
virtualisation.qemu.options = ["-smp 12"];
Now you can simply specify:
virtualisation.cores = 12;
It was asked by @CMCDragonkai to elaborate on that, so let's just do
this by actually providing a code comment.

The xrandrHeads option has been there since a long time, so there is no
need to advertise it as a new feature.
Instead, let's focus on just what has changed, which is that we now
assign one head to be primary.

Using invalid module options in the submodule isn't very nice, because
it doesn't give very useful errors in case of type mismatch, also we
don't get descriptions of these options as they're effecively
nonexistent to the module system. Another downside of this is that
merging of these options isn't done correctly as well (eg. for
types.lines).
So we now have proper submodules for each xrandrHead and we also use
corcedTo in the type of xrandrHeads so that we can populate the
submodule's "output" option in case a plain string is defined for a list
item.
Instead of silently skipping multiple primary heads, we now have an
assertion, which displays a message and aborts configuration evaluation
appropriately.

This changes much of the make-disk-image.nix logic (and thus most NixOS
image building) to use LKL to set up the target directory structure rather
than a Linux VM. The only work we still do in a VM is less IO-heavy stuff
that while still time-consuming, is less of the overall load. The goal is
to kill more of that stuff, but that will require deeper changes to NixOS
activation scripts and switch-to-configuration.pl, and I don't want to
bite off too much at once.
* programs.zsh: factor zsh-syntax-highlighting out into its own module
* programs.zsh.syntax-highlighting: add `highlighters` option
* programs.zsh: document BC break introduced by moving zsh-syntax-completion into its own module
This is currently our default display manager, so I'm adding this to the
"tested" job as well to ensure we don't ship broken revisions where X is
most likely not working.
The test uses a custom SLiM theme that's specifically tailored for good
OCR results (mainly white background and black fonts without anything
else), because our default NixOS theme has a very small contrast between
background and fonts in some places.
