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.
At some point we probably want to replace this with a curated list
of configurations or even an upstreamed repository of examples, but
for now this is just noise.

These values match against the client IDs only, so let's rename it to
something that actually reflects that. Having client.cert in the same

Referring to the GnuTLS documentation isn't very nice if the user has to
use a search engine to find that documentation. So let's directly link
to it.
The type was "str" before, but it's actually a colon-separated string,
so if we set options in multiple modules, the result is one concatenated
string.
I know there is types.envVar, which does the same as separatedString ":"
but I found that it could confuse the reader of the Taskserver module.

We already document that we allow special values such as "all" and

Using nixos-taskserver is more verbose but less cryptic and I think it
fits the purpose better because it can't be confused to be a wrapper
around the taskdctl command from the upstream project as
nixos-taskserver shares no commonalities with it.

A small test which checks whether tasks can be synced using the
Taskserver.
It doesn't test group functionality because I suspect that they're not
yet implemented upstream. I haven't done an in-depth check on that but I
couldn't find a method of linking groups to users yet so I guess this
will get in with one of the text releases of Taskwarrior/Taskserver.

Finally, this is where we declaratively set up our organisations and
users/groups, which looks like this in the system configuration:
services.taskserver.organisations.NixOS.users = [ "alice" "bob" ];
This automatically sets up "alice" and "bob" for the "NixOS"
organisation, generates the required client keys and signs it via the
CA.
However, we still need to use nixos-taskdctl export-user in order to
import these certificates on the client.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
It's a helper for NixOS systems to make it easier to handle CA
certificate signing, similar to what taskd provides but comes preseeded
with the values from the system configuration.
The tool is very limited at the moment and only allows to *add*
organisations, users and groups. Deletion and suspension however is much
simpler to implement, because we don't need to handle certificate
signing.
Another limitation is that we don't take into account whether
certificates and keys are already set in the system configuration and if
they're set it will fail spectacularly.
For passing the commands to the taskd command, we're using a small C
program which does setuid() and setgid() to the Taskserver user and
group, because runuser(1) needs PAM (quite pointless if you're already
root) and su(1) doesn't allow for setting the group and setgid()s to the
default group of the user, so it even doesn't work in conjunction with
sg(1).
In summary, we now have a shiny nixos-taskdctl command, which lets us do
things like:
nixos-taskdctl add-org NixOS
nixos-taskdctl add-user NixOS alice
nixos-taskdctl export-user NixOS alice
The last command writes a series of shell commands to stdout, which then
can be imported on the client by piping it into a shell as well as doing
it for example via SSH:
ssh root@server nixos-taskdctl export-user NixOS alice | sh
Of course, in terms of security we need to improve this even further so
that we generate the private key on the client and just send a CSR to
the server so that we don't need to push any secrets over the wire.

The server starts up without that option anyway, but it complains about
its value not being set. As we probably want to have access to that
configuration value anyway, let's expose this via the NixOS module as
well.

Now the service starts up if only the services.taskserver.enable option
is set to true.
We now also have three systemd services (started in this order):
* taskserver-init: For creating the necessary data directory and also
includes a refecence to the configuration file in
the Nix store.
* taskserver-ca: Only enabled if none of the server.key, server.cert,
server.crl and caCert options are set, so we can
allow for certificates that are issued by another
CA.
This service creates a new CA key+certificate and a
server key+certificate and signs the latter using
the CA key.
The permissions of these keys/certs are set quite
strictly to allow only the root user to sign
certificates.
* taskserver: The main Taskserver service which just starts taskd.
We now also log to stdout and thus to the journal.
Of course, there are still a few problems left to solve, for instance:
* The CA currently only signs the server certificates, so it's
only usable for clients if the server doesn't validate client certs
(which is kinda pointless).
* Using "taskd <command>" is currently still a bit awkward to use, so
we need to properly wrap it in environment.systemPackages to set the
dataDir by default.
* There are still a few configuration options left to include, for
example the "trust" option.
* We might want to introduce an extraConfig option.
* It might be useful to allow for declarative configuration of
organisations and users, especially when it comes to creating client
certificates.
* The right signal has to be sent for the taskserver service to reload
properly.
* Currently the CA and server certificates are created using
server.host as the common name and doesn't set additional certificate
information. This could be improved by adding options that explicitly
set that information.
As for the config file, we might need to patch taskd to allow for
setting not only --data but also a --cfgfile, which then omits the
${dataDir}/config file. We can still use the "include" directive from
the file specified using --cfgfile in order to chainload
${dataDir}/config.

The descriptions for the options previously seem to be from the
taskdrc(5) manual page. So in cases where they didn't make sense for us
I changed the wording a bit (for example for client.deny we don't have a
"comma-separated list".
Also, I've reordered things a bit for consistency (type, default,
example and then description) and add missing types, examples and
docbook tags.
Options that are not used by default now have a null value, so that we
can generate a configuration file out of all the options defined for the
module.
The dataDir default value is now /var/lib/taskserver, because it doesn't
make sense to put just yet another empty subdirectory in it and "data"
doesn't quite make sense anyway, because it also contains the
configuration file as well.

Unetbootin works by altering the image and placing a boot loader on it.
For this reason, it cannot work with UEFI and the installation guides

Most of the desktop environments will spawn pulseaudio, but we can instead simply run it as a systemd service instead.
This patch also makes the system wide service run in foreground as recommended by the systemd projects and allows it to use sd_notify to signal ready instead of reading a pid written to a file. It is now also restarted on failure.
The user version has been tested with KDE and works fine there.
The system-wide version runs, but I haven't actually used it and upstream does not recommend running in this mode.
This patch makes dbus launch with any user session instead of
leaving it up to the desktop environment launch script to run it.
It has been tested with KDE, which simply uses the running daemon
instead of launching its own.
This is upstream's recommended way to run dbus.

A testcase each for

Seems odd to define the container IPs with their prefix length attached.
There should be a better way…
- declarative bridged container
Also fix the ping test by waiting for the container to start
When the ping was executed, the container might not have finished starting. Or
the host-side of the container wasn't finished with config. Waiting for
2 seconds in between fixes this.
This allows the containers to have their interface in a bridge on the host.
Also this adds IPv6 addresses to the containers both with bridged and unbridged
network.

NixOps has infrequent releases, so it's not the best place for keeping

I had the basic version of this laying around for some while but didn't
continue on it. Originally it was for testing support for the Neo layout
introduced back then (8cd6d53).
We only test the first three Neo layers, because the last three layers
are largely comprised of special characters and in addition to that the
support for the VT keymap seems to be limited compared to the Xorg
keymap.
Yesterday @NicolasPetton on IRC had troubles with the Colemak layout
(IRC logs: http://nixos.org/irc/logs/log.20160330, starting at 16:08)
and I found that test again, so I went for improving and adding to
<nixpkgs>.
While the original problem seemed to be related to GDM, we can still add
another subtest that checks whether GDM correctly applies the keyboard
layout. However I don't have a clue how to properly configure the
keyboard layout on GDM, at least not within the NixOS configuration.
The main goal of this test is not to test a complete set of all key
mappings but to check whether the keymap is loaded and working at all.
It also serves as an example for NixOS keyboard configurations.
The list of keyboard layouts is by no means complete, so everybody is
free to add their own to the test or improve the existing ones.

in subshells) doesn't hold. Note that we already have some convenience
aliases that don't work in subshells either (such as "ll").
Previously, the cisco resolver was used on the theory that it would
provide the best user experience regardless of location. The downsides
of cisco are 1) logging; 2) missing supoprt for DNS security extensions.
The new upstream resolver is located in Holland, supports DNS security,
and *claims* to not log activity. For users outside of Europe, this will
mean reduced performance, but I believe it's a worthy tradeoff.

When iodined tries to start before any interface other than loopback has an ip, iodined fails.
Wait for ip-up.target
The above is because of the following:
in iodined's code: src/common.c line 157
the flag AI_ADDRCONFIG is passed as a flag to getaddrinfo.
Iodine uses the function
get_addr(char *host,
int port,
int addr_family,
int flags,
struct sockaddr_storage *out);
to get address information via getaddrinfo().
Within get_addr, the flag AI_ADDRCONFIG is forced.
What this flag does, is cause getaddrinfo to return
"Name or service not known" as an error explicitly if no ip
has been assigned to the computer.

wanted to avoid this ambiguity entirely).

GnuPG 2.1.x changed the way the gpg-agent works, and that new approach no
longer requires (or even supports) the "start everything as a child of the

To configure the gpg-agent for your X session, add the following code to
~/.xsession or some other appropriate place that's sourced at start-up:
gpg-connect-agent /bye
GPG_TTY=$(tty)
export GPG_TTY
If you want to use gpg-agent for SSH, too, also add the settings
unset SSH_AGENT_PID
export SSH_AUTH_SOCK="${HOME}/.gnupg/S.gpg-agent.ssh"
and make sure that
enable-ssh-support
is included in your ~/.gnupg/gpg-agent.conf.

Probably not many people care about i686-linux any more, but building
all these images is fairly expensive (e.g. in the worst case, every

disk image, one to convert to OVA, one to add a hydra-build-products

us from hitting hydra-queue-runner's size limit of 2 GiB.

This splits a few NixOS tests (namely Chromium, VirtualBox and the
networking tests) into several subtests that are exposed via attributes.
The networking tests were already split up but they didn't expose an
attribute set of available tests but used a function attribute to

A new function callSubTests in nixos/release.nix is now responsible for
gathering subtests, which is also used for the installer and boot tests.
The latter is now placed in a tests.boot.* namespace rather than
"polluting" the tests attribute set with its subtest.

"Looks like that cleans things up quite a bit! Just one aesthetics note,
