Adds /dev/disk/by-{id,label}/* symlinks for bcache device nodes, in the
final rootfs.
Symlinks will only be created for bcache devices that contain
filesystems. So if you have a blank bcache device or run LVM on top of
bcache you will not get this kind of symlink.
Or else `services.udev.packages = [ bcache-tools ]` cannot be used.
To not break bcache in the initrd I'm modifying this in stage-1.nix:
- --replace /bin/sh ${extraUtils}/bin/sh
+ --replace ${bash}/bin/sh ${extraUtils}/bin/sh
Reasoning behind that change:
* If not modifying the /bin/sh pattern in any way, it will also match
${bash}/bin/sh, creating a broken path like
/nix/store/HASH-bash/nix/store/HASH-bash/bin/sh in the udev rule file.
* The addition of /bin/sh was done in 775f381a9e
("stage-1: add bcache support"). It seems somewhat plausible that
no new users have appeared since then and we can take this opportunity
to back out of this change without much fear of regressions.
If there _are_ regressions, they should be in the form of build time
errors, not runtime (boot), due to how the udev rule output is checked
for invalid path references. So low risk, IMHO.
* An alternative approach could be to copy the /bin/sh substitute rule
over to the non-initrd udev rules implementation in NixOS, but I think
this way is better:
- The rules file comes with a working path out of the box.
- We can use more precise pattern matching when modifying the udev
rules for the initrd.
The default font is unreadably small on some hidpi displays. This
makes it possible to specify a TrueType or OpenType font at any point
size, and it will automatically be converted to the format the Grub
uses.
This adds configuration options for the bind package so that the
interfaces that bind listens on can be configured rather than just
hardcoded as any. The default values preserve the old behavior to be
backwards compatible.
* Create "full.pem" from selfsigned certificate
* Tell simp_le to create "full.pem"
* Inject service dependency between lighttpd and the generation of certificates
Side note: According to the internet these servers also use the
"full.pem" format: pound, ejabberd, pure-ftpd.
Restructure the nixos-artwork to make it easy to selectively

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.

OVMF{,CODE,VARS}.fd are now available in a dedicated fd output, greatly

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.

Before NixOS 17.03, we were using dd-agent 5.5.X which

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

Move hidepid test from misc, so that misc can go back to testing a vanilla

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

This eliminates a theoretical risk of ASLR bypass due to the fixed address

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

an effort to make the transition smoother. For 17.09 all of it should
probably be pruned.

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"];

The xrandrHeads option has been there since a long time, so there is no

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.

The idea is to provide a convenient way to enable most vanilla hardening
features in one go. The hardened profile, then, will serve as a place for
features that enhance security but cannot be enabled for all deployments
because they interfere with legitimate use cases (e.g., using ptrace to
debug problems in an already running process).

The "simpleUefiGummiboot" installer test fails since this commit,
because that commit introduced a small check to verify whether the store
was altered.
While installing NixOS for the first time, the store is usually in
/mnt/nix/store and without the read-only bind mount that's preventing
programs from altering the store.
So after nixos-install is done creating the system closure and setting
it as the active system profile, the bootloader is written from the
closure inside the chroot. The systemd-boot-builder is invoked during
this step, which adds .pyc files for various Python modules of the
Python 3 store path, which in turn invalidates the hash of the Python 3
store path itself.
At the time the system is booted up again, the nix-store is verified and
fails with something like this:

The key distinction I'm drawing is that there's a component that deals
with the store of the machine being built, and another component for
the store building it. The inner part of it assumes nothing from the
builder (doesn't need chroot or root powers) so it can run comfortably
inside a Nix build, as well as nixos-rebuild. I have some upcoming work
that will use that to significantly speed up and streamline image builds
for NixOS, especially on virtualized hosts like EC2, but it's also a
reasonable speedup on native hosts.

This change fixes two major issues:

2. Newer versions of Plex keep metadata in the

we copy into `/var/lib/plex/.skeleton`. If we copy the empty

First of all, we're now using ImageMagick to improve the screenshot so
that Tesseract has an esier time to recognize the text. The resulting
image of this post-processing is a scaled up black-and-white version
with the backgrounds almost entirely removed and the text edges a bit
blurred, so the screen shots now more or less resemble an image from a
scanner rather. This is what Tesseract is trained for by default.
As mentioned in the previous commit we now also use Tesseract 4, which
further improves the quality of text recognition.
I've spent countless hours just to test different postprocessing
variants and testing what works best for our tests and this is the one
that worked best so far. It's certainly not perfect and I'd like to
avoid the scaling step but we're way better off than before.
In addition to this, the OCR process is now done without an intermediate
file, solely using pipes.
I've tested this using the following VM tests which have OCR enabled:
* nixos/tests/chromium.nix -A stable
* nixos/tests/emacs-daemon.nix
* nixos/tests/installer.nix -A luksroot
* nixos/tests/lightdm.nix
* nixos/tests/plasma5.nix
* nixos/tests/sddm.nix
All of the tests still succeed and comparing some of the recognition
results to the earlier results it now also detects a lot more text than
before this commit.

I've removed that attribute in 68bc260ca2,
because the language files no longer were distributed as seperate files,
but if we for example only want to use the English training data, the
closure size of Tesseract gets quite large (around 1.2 GB), which is a
bit much just to be able to run NixOS VM tests.
For this reason I've also switched the VM tests back to using only the
English language.
Tested using the following VM tests (the ones that have OCR enabled) on
x86_64-linux:

gyre-fonts provides high-quality TrueType substitutes for standard PostScript

The LUKS header can be on another device (e.g. a USB stick). In my case
it can take up to two seconds until the partition on my USB stick is
available (i.e. the decryption fails without this patch). This will also
remove some redundancy by providing the shell function `wait_target` and
slightly improve the output (one "." per second and a success/failure
indication after 10 seconds instead of always printing "ok").
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.
