The update-resolve-conf script from the update-resolv-conf
package is very useful and should work in most of the common
cases, so this adds an option to enable it. The option is
disabled by default for backwards compatibility.
So far the module only allowed for the ccid driver, but there are a lot
of other PCSC driver modules out there, so let's add an option called
"plugins", which boils down to a store path that links together all the
paths specified.
We don't need to create stuff in /var/lib/pcsc anymore, because we
patched pcsclite to allow setting PCSCLITE_HP_DROPDIR.
Another new option is readerConfig, which is especially useful for
non-USB readers that aren't autodetected.
The systemd service now is no longer Type=forking, because we're now
passing the -f (foreground) option to pcscd.
Tested against a YubiKey 4, SCR335 and a REINER SCT USB reader.

This was originally removed in d4d0e449d7.
The intent was not to maintain hydra expression at two places.
Nowadays we have enough devs to maintain this despite copy/pasta.
This should encourage more people to use Hydra, which is a really
great piece of software together with Nix.
Tested a deploy using https://github.com/peti/hydra-tutorial
... 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.)
This reverts commit c25907d072.
I think this commit broke the NixOS service for NetworkManager. At least
with this, and the two previous reverts, everything is back to normal.
(With multiple-outputs split, it would have reduced the closure size by
3 MiB.)
This reverts commit 7ac1ef05fa.
One of a few reverts needed to unbreak networkmanager NixOS service
since the multiple-output split (to save 3 MiB of closure size).

Move Subsonic state directory from `/var/subsonic` to
`/var/lib/subsonic`, since the general convention is for each
application to put its state directory there.
Also, automatically set the home directory of the `subsonic` user to the
value of `config.services.subsonic.home`, rather than setting it to a
value hardcoded in the module. This keeps the home directory of the
`subsonic` user and the state directory for the Subsonic application in
sync.
leveraging users.users.<user>.createHome instead of a preStart script.
preStart script is still required to ensure proper creation of logging
directory.
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.
Instead of using this option, please modify the dovecot package by means of an

* 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.

Note: I ignored the C++ libraries, but it appears we're not currently
using them. Once we do, we'll probably want to put them in a separate
output as well (to prevent non-C++ users from depending on Boost).
Need to pass `cups.out` to `systemd.packages`, lest we end up with an invalid
generated unit containing only directives set in the service module.
This patch gives us a valid cups.service unit but, vexingly, does not fix the
test failure at NixOS/nixpkgs#14748
`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.

This adds a Taskserver module along with documentation and a small
helper tool which eases managing a custom CA along with Taskserver
organisations, users and groups.
Taskserver is the server component of Taskwarrior, a TODO list
application for the command line.
The work has been started by @matthiasbeyer back in mid 2015 and I have
continued to work on it recently, so this merge contains commits from
both of us.
Thanks particularly to @nbp and @matthiasbeyer for reviewing and
suggesting improvements.
I've tested this with the new test (nixos/tests/taskserver.nix) this
branch adds and it fails because of the changes introduced by the

This is simply to add configuration lines to the generated configuration
file. The reason why I didn't went for an attribute set is that the
taskdrc file format doesn't map very well on Nix attributes, for example
the following can be set in taskdrc:
server = somestring
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
we'd have to do something like this:
{ server._top = somestring;
server.key = anotherstring;
}
Of course, this would work as well but nothing is more simple than just
appending raw strings.

At least this should allow for some customisation of how the
certificates and keys are created. We now have two sub-namespaces within

Whenever the nixos-taskserver tool was invoked manually for creating an
organisation/group/user we now add an empty file called .imperative to
the data directory.
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

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.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
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

Right now the expiration_days is set to 10 years, but that's merely to

prompt for user input.

It doesn't do much harm to make the server certificate world readable,

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

What I have in mind is that instead of that crappy --service-helper

module option.

that organisations, users and groups get properly deleted if they're

It's not necessarily related to the PKI options, because this is also

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

well.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
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.
