Since systemd version 230, it is required to have a machine-id file
prior to the startup of the container. If the file is empty, a transient
machine ID is generated by systemd-nspawn.
See systemd/systemd#3014 for more details on the matter.
This unbreaks all of the containers-* NixOS tests.

Closes: #15808
The primary motivation here is to get rid of builderDefs, but now the
resulting font directory is also linked into /run/current-system/sw,
which fixes #15194.
VBoxService needs dbus in order to work properly, which failed to start
up so far, because it was searching in /run/current-system/sw for its
configuration files.
We now no longer run with the --system flag but specify the
configuration file directly instead.
This fixes at least the "simple-gui" test and probably the others as
well, which I haven't tested yet.

The existence of $root/var/lib/private/host-notify as a socket
prevented a bind mount:
container foo[8083]: Failed to create mount point /var/lib/containers/foo/var/lib/private/host-notify: No such device or address
The VirtualBox tests so far ran the X server as root instead of user
"alice" and it did work, because we had access control turned off by
default.
Fortunately, it was changed in 1541fa351b.
As a side effect, it caused all the VirtualBox tests to fail because
they now can't connect to the X server, which is a good thing because
it's a bug of the VirtualBox tests.
So to fix it, let's just start the X server as user alice.

Regression introduced by d84741a4bf.
The mentioned commit actually is a good thing, because we now get the
output from the X session.
Unfortunately, for the i3wm test, the i3-config-wizard prints out the
raw keyboard symbols directly coming from xcb, so the output isn't
necessarily proper UTF-8.
As the XML::Writer already expects valid UTF-8 input, we assume that
everything that comes into sanitise() will be UTF-8 from the start. So
we just decode() it using FB_DEFAULT as the check argument so that
every invalid character is replaced by the unicode replacement
character:
https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character
We simply re-oncode it again afterwards and return it, so we should
always get out valid UTF-8 in the log XML.

This allows setting options for the same LUKS device in different
modules. For example, the auto-generated hardware-configuration.nix
can contain
boot.initrd.luks.devices.crypted.device = "/dev/disk/...";
while configuration.nix can add
boot.initrd.luks.devices.crypted.allowDiscards = true;
Also updated the examples/docs to use /disk/disk/by-uuid instead of
/dev/sda, since we shouldn't promote the use of the latter.
... rather than ~/.xsession-errors. It might make sense to make this
the default, in order to eliminate ad hoc, uncentralised, poorly
discoverable log files.
This ensures that "journalctl -u display-manager" does what you would
expect in 2016. However, the main reason is to ensure that our VM
tests show the output of the X server.
A slight problem is that with KDE user switching, messages from the
various X servers end up in the same place. However, that's an
improvement over the previous situation, where the second X server
would overwrite the /var/log/X.0.log of the first. (This was caused by
the fact that we were passing a hard-coded value for -logfile.)
For now, leave the old implementation under `man-old` attribute.
Small warning: I had a leftover ~/.nix-profile/man from an old package,
which caused man-db's man prefer it and ignore ~/.nix-profile/share/man.

Move Subsonic state directory from `/var/subsonic` to

application to put its state directory there.
Also, automatically set the home directory of the `subsonic` user to the

value hardcoded in the module. This keeps the home directory of the
`subsonic` user and the state directory for the Subsonic application in

The chroot caps restriction disallows chroot'ed processes from running
any command that requires `CAP_SYS_ADMIN`, breaking `nixos-rebuild`. See
e.g., https://github.com/NixOS/nixpkgs/issues/15293
This significantly weakens chroot protections, but to break
nixos-rebuild out of the box is too severe.
The list of public proxies is updated now and again and it's probably a
good idea to always work from the most recent list, rather than the one
that is shipped with the release. This can be crucial in case of
resolvers that are revealed to have gone rogue or otherwise have been
compromised.
As @edolstra pointed out that the kernel module might be painful to
maintain. I strongly disagree because it's only a small module and it's
good to have such a canary in the tests no matter how the bootup process
looks like, so I'm going the masochistic route and try to maintain it.
If it *really* becomes too much maintenance burden, we can still drop or
disable kcanary.

We already have a small regression test for #15226 within the swraid
installer test. Unfortunately, we only check there whether the md
kthread got signalled but not whether other rampaging processes are
still alive that *should* have been killed.
So in order to do this we provide multiple canary processes which are
checked after the system has booted up:
* canary1: It's a simple forking daemon which just sleeps until it's
going to be killed. Of course we expect this process to not
be alive anymore after boot up.
* canary2: Similar to canary1, but tries to mimick a kthread to make
sure that it's going to be properly killed at the end of
stage 1.
* canary3: Like canary2, but this time using a @ in front of its
command name to actually prevent it from being killed.
* kcanary: This one is a real kthread and it runs until killed, which
shouldn't be the case.
Tested with and without 67223ee and everything works as expected, at
least on my machine.

Unfortunately, pkill doesn't distinguish between kernel and user space
processes, so we need to make sure we don't accidentally kill kernel
threads.
Normally, a kernel thread ignores all signals, but there are a few that
do. A quick grep on the kernel source tree (as of kernel 4.6.0) shows
the following source files which use allow_signal():
drivers/isdn/mISDN/l1oip_core.c
drivers/md/md.c
drivers/misc/mic/cosm/cosm_scif_server.c
drivers/misc/mic/cosm_client/cosm_scif_client.c
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c
drivers/staging/rtl8188eu/core/rtw_cmd.c

drivers/target/iscsi/iscsi_target_nego.c
drivers/usb/atm/usbatm.c
drivers/usb/gadget/function/f_mass_storage.c
fs/jffs2/background.c
fs/lockd/clntlock.c
fs/lockd/svc.c
fs/nfs/nfs4state.c
fs/nfsd/nfssvc.c
While not all of these are necessarily kthreads and some functionality
may still be unimpeded, it's still quite harmful and can cause
unexpected side-effects, especially because some of these kthreads are
storage-related (which we obviously don't want to kill during bootup).
During discussion at #15226, @dezgeg suggested the following
implementation:
for pid in $(pgrep -v -f '@'); do
if [ "$(cat /proc/$pid/cmdline)" != "" ]; then
kill -9 "$pid"
fi
done
This has a few downsides:
* User space processes which use an empty string in their command line
won't be killed.
* It results in errors during bootup because some shell-related
processes are already terminated (maybe it's pgrep itself, haven't
checked).
* The @ is searched within the full command line, not just at the
beginning of the string. Of course, we already had this until now, so
it's not a problem of his implementation.
I posted an alternative implementation which doesn't suffer from the
first point, but even that one wasn't sufficient:
for pid in $(pgrep -v -f '^@'); do
readlink "/proc/$pid/exe" &> /dev/null || continue
echo "$pid"
done | xargs kill -9
This one spawns a subshell, which would be included in the processes to
kill and actually kills itself during the process.
So what we have now is even checking whether the shell process itself is
in the list to kill and avoids killing it just to be sure.
Also, we don't spawn a subshell anymore and use /proc/$pid/exe to
distinguish between user space and kernel processes like in the comments
of the following StackOverflow answer:
http://stackoverflow.com/a/12231039
We don't need to take care of terminating processes, because what we
actually want IS to terminate the processes.
The only point where this (and any previous) approach falls short if we
have processes that act like fork bombs, because they might spawn
additional processes between the pgrep and the killing. We can only
address this with process/control groups and this still won't save us
because the root user can escape from that as well.

Instead of disabling the channels via removing the channel mapping from
the tests themselves, let's just explicitly reference the stable test in

It's not the job of Nixpkgs to distribute beta versions of upstream
packages. More importantly, building these delays channel updates by
several hours, which is bad for our security fix turnaround time.
* Perform HTTP HEAD request instead of full GET (lighter weight)
* Don't log output of curl to the journal (it's noise/debug)
* Use explicit http:// URL scheme
* Reduce poll interval from 10s to 2s (respond to state changes
quicker). Probably not relevant on boot (lots of services compete for
the CPU), but online service restarts/reloads should be quicker.
* Pass --fail to curl (should be more robust against false positives)
* Use 4 space indent for shell code.
The current postStart code holds Jenkins off the "started" state until
Jenkins becomes idle. But it should be enough to wait until Jenkins
start handling HTTP requests to consider it "started".
More reasons why the current approach is bad and we should remove it,
from @coreyoconnor in
https://github.com/NixOS/nixpkgs/issues/14991#issuecomment-216572571:
1. Repeatedly curling for a specific human-readable string to
determine "Active" is fragile. For instance, what happens when jenkins
is localized?
2. The time jenkins takes to initializes is variable. This (at least
used to) depend on the number of jobs and any plugin upgrades requested.
3. Jenkins can be requested to restart from the UI. Which will not
affect the status of the service. This means that the service being
"active" does not imply jenkins is initialized. Downstream services
cannot assume jenkins is initialized if the service is active. Might
as well accept that and remove the initialized test from service
startup.

A user noticed the example for `hosts`, took the `mode` permissions literally, and ended up with surprising behavior on their system. Updating the documentation to not reference a real config file which might have real permissions requirements.
The pre-sleep service exits if any command fails. Unloading facetimehd
without it being loaded blocks subsequent commands from running.
Note: `modprobe -r` works a bit better when unloading unused modules,
and is preferrable to `rmmod`. However, the facetimehd module does not
support suspending. In this case, it seems preferable to forcefully
unload the module. `modprobe` does not support a `--force` flag when
removing, so we are left with `rmmod`.

This command was useful when NixOS was spread across multiple

`dbus-launch` is executed early in the script, before desktop managers
had a chance to setup the environment. If DBus activation is used,
applications launched by this may therefore lack necessary environment
variables. This patch sends the complete environment to DBus after
launching the desktop manager.
With the merge of the closure-size branch, most packages now have
multiple outputs. One of these packages is gnutls, so previously
everything that we needed was to reference "${gnutls}/bin/..." and now
we need to use "${gnutls.bin}/bin/...".
So it's not a very big issue to fix.

My first attempt to do this was to just use a conditional <refsection/>
in order to not create exact references in the manpage but create the
reference in the HTML manual, as suggested by @edolstra on IRC.
Later I went on to use <olink/> to reference sections of the manual, but
in order to do that, we need to overhaul how we generate the manual and
manpages.
So, that's where we are now:
There is a new derivation called "manual-olinkdb", which is the olinkdb
for the HTML manual, which in turn creates the olinkdb.xml file and the
manual.db. The former contains the targetdoc references and the latter
the specific targetptr elements.
The reason why I included the olinkdb.xml verbatim is that first of all
the DTD is dependent on the Docbook XSL sources and the references
within the olinkdb.xml entities are relative to the current directory.
So using a store path for that would end up searching for the manual.db
directly in /nix/store/manual.db.
Unfortunately, the <olinks/> that end up in the output file are
relative, so for example if you're clicking on one of these within the
PDF, the URL is searched in the current directory.
However, the sections from the olink's text are still valid, so we could
use an alternative URL for that in the future.
The manual doesn't contain any links, so even referencing the relative
URL shouldn't do any harm.

This is simply to add configuration lines to the generated configuration

the following can be set in taskdrc:

server.key = anotherstring
In order to use a Nix attribute set for that, it would be way too
complicated, for example if we want to represent the mentioned example

During the preStart of the Taskserver service, we use process-json which
in turn now checks whether those .imperative files exist and if so, it
doesn't do anything with it.
This should now ensure that whenever there is a manually created user,
it doesn't get killed off by the declarative configuration in case it
shouldn't exist within that configuration.
In addition, we also add a small subtest to check whether this is
happening or not and fail if the imperatively created user got deleted
by process-json.

We only print the output whenever there is an error, otherwise let's
shut it up because it only shows information the user can gather through
other means. For example by invoking certtool manually, or by just
looking at private key files (the whole blurb it's outputting is in
there as well).

We were putting the whole output of "nixos-taskserver export-user" from
the server to the respective client and on every such operation the
whole output was shown again in the test log.
Now we're *only* showing these details whenever a user import fails on
the client.

Now we finally can delete organisations, groups and users along with
certificate revocation. The new subtests now make sure that the client
certificate is also revoked (both when removing the whole organisation
and just a single user).
If we use the imperative way to add and delete users, we have to restart
the Taskserver in order for the CRL to be effective.
However, by using the declarative configuration we now get this for
free, because removing a user will also restart the service and thus its
client certificate will end up in the CRL.

Unfortunately we don't have a better way to check whether the reload has
been done successfully, but at least we now *can* reload it without
figuring out the exact signal to send to the process.
Note that on reload, Taskserver will not reload the CRL file. For that
to work, a full restart needs to be done.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
If we want to revoke client certificates and want the server to actually
notice the revocation, we need to have a valid certificate revocation
list.
Right now the expiration_days is set to 10 years, but that's merely to
actually get certtool to actually generate the CRL without trying to
prompt for user input.

It doesn't do much harm to make the server certificate world readable,
because even though it's not accessible anymore via the file system,
someone can still get it by simply doing a TLS handshake with the
server.
So this is solely for consistency.

We now no longer have the stupid --service-helper option, which silences
messages about already existing organisations, users or groups.
Instead of that option, we now have a new subcommand called
"process-json", which accepts a JSON file directly from the specified
NixOS module options and creates/deletes the users accordingly.
Note that this still has a two issues left to solve in this area:
* Deletion is not supported yet.
* If a user is created imperatively, the next run of process-json will
delete it once deletion is supported.
So we need to implement deletion and a way to mark organisations, users
and groups as "imperatively managed".

The Click functions really are for the command line and should be solely
used for that.
What I have in mind is that instead of that crappy --service-helper
argument, we should really have a new subcommand that is expecting JSON
which is directly coming from the services.taskserver.organisations
module option.
That way we can decrease even more boilerplate and we can also ensure
that organisations, users and groups get properly deleted if they're
removed from the NixOS configuration.

With <olink/> support in place, we can now reference the Taskserver
section within the NixOS manual, so that users reading the manpage of
configuration.nix(5) won't miss this information.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
My first attempt to do this was to just use a conditional <refsection/>
in order to not create exact references in the manpage but create the
reference in the HTML manual, as suggested by @edolstra on IRC.
Later I went on to use <olink/> to reference sections of the manual, but
in order to do that, we need to overhaul how we generate the manual and
manpages.
So, that's where we are now:
There is a new derivation called "manual-olinkdb", which is the olinkdb
for the HTML manual, which in turn creates the olinkdb.xml file and the
manual.db. The former contains the targetdoc references and the latter
the specific targetptr elements.
The reason why I included the olinkdb.xml verbatim is that first of all
the DTD is dependent on the Docbook XSL sources and the references
within the olinkdb.xml entities are relative to the current directory.
So using a store path for that would end up searching for the manual.db
directly in /nix/store/manual.db.
Unfortunately, the <olinks/> that end up in the output file are
relative, so for example if you're clicking on one of these within the
PDF, the URL is searched in the current directory.
However, the sections from the olink's text are still valid, so we could
use an alternative URL for that in the future.
The manual doesn't contain any links, so even referencing the relative
URL shouldn't do any harm.

We're now using .pki.server.* and .pki.ca.* so that it's entirely clear
what these keys/certificates are for. For example we had just .pki.key
before, which doesn't really tell very much about what it's for except
if you look at the option description.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
The improvement here is just that we're adding a big <note/> here so
that users of these options are aware that whenever they're setting one
of these the certificates and keys are _not_ created automatically.

This is clearly a server configuration option and has nothing to do with
certificate creation and signing, so let's move it away from the .pki
namespace.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
It's not necessarily related to the PKI options, because this is also
used for setting the server address on the Taskwarrior client.
So if someone doesn't have his/her own certificates from another CA, all
options that need to be adjusted are in .pki. And if someone doesn't
want to bother with getting certificates from another CA, (s)he just
doesn't set anything in .pki.

After moving out the PKI-unrelated options, let's name this a bit more
appropriate, so we can finally get rid of the taskserver.server thing.
This also moves taskserver.caCert to taskserver.pki.caCert, because that
clearly belongs to the PKI options.

Having an option called services.taskserver.server.host is quite
confusing because we already have "server" in the service name, so let's
first get rid of the listening options before we rename the rest of the
options in that .server attribute.

As the nixos-taskserver command can also be used to imperatively manage
users, we need to test this as well.

In the comments of the pull request @nbp wrote:
"Why is it implemented in 3 different languages: Nix, Bash and C?"
And he's right, it doesn't make sense, because we were using C as a
runuser replacement and used Nix to generate the shellscript
boilerplates.
Writing this in Python gets rid of all of this and we also don't need
the boilerplate as well, because we're using Click to handle all the
command line stuff.
Note that this currently is a 1:1 implementation of what we had before.

The option is solely for debugging purposes (particularly the unit tests
of the project itself) and doesn't make sense to include it in the NixOS
module options.
If people want to use this, we might want to introduce another option so
that we can insert arbitrary configuration lines.

Commit 98d9bba introduced this option as a nullOr type and it actually
checks whether null has been set and only appends -dpi if that's the
case. So let's actually set the default to null instead of 0.

This module adds an option `security.hideProcessInformation` that, when
enabled, restricts access to process information such as command-line
arguments to the process owner. The module adds a static group "proc"
whose members are exempt from process information hiding.
Ideally, this feature would be implemented by simply adding the
appropriate mount options to `fileSystems."/proc".fsOptions`, but this
was found to not work in vmtests. To ensure that process information
hiding is enforced, we use a systemd service unit that remounts `/proc`
after `systemd-remount-fs.service` has completed.
To verify the correctness of the feature, simple tests were added to
nixos/tests/misc: the test ensures that unprivileged users cannot see
process information owned by another user, while members of "proc" CAN.
Thanks to @abbradar for feedback and suggestions.
