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 is the recommended way for long-running services and ensures that
Taskserver will keep running until it has been stopped manually.

Using requiredBy is a bad idea for the initialisation units, because
whenever the Taskserver service is restarted the initialisation units
get restarted as well.
Also, make sure taskserver-init.service will be ordered *before*
taskserver.service.

The Taskserver doesn't need access to the full /dev nor does it need a
shared /tmp. In addition, the initialisation services don't need network
access, so let's constrain them to the loopback device.

As suggested by @matthiasbeyer:
"We might add a short note that this port has to be opened in the
firewall, or is this done by the service automatically?"
This commit now adds the listenPort to
networking.firewall.allowedTCPPorts as soon as the listenHost is not
"localhost".
In addition to that, this is now also documented in the listenHost
option declaration and I have removed disabling of the firewall from the
VM test.

No changes in functionality but rather just restructuring the module
definitions to be one mkMerge, which now uses mkIf from the top-level
scope of the CA initialization service so we can better abstract
additional options we might need there.

We want to make sure that the helper tool won't work if the automatic CA
wasn't properly set up. This not only avoids race conditions if the tool
is started before the actual service is running but it also fails if
something during CA setup has failed so the user can investigate what
went wrong.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
We need to explicitly make sure the CA is created before we actually
launch the main Taskserver service in order to avoid race conditions
where the preStart phase of the main service could possibly corrupt
certificates if it would be started in parallel.

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
PKI so it should be more clear which options you have to set if you want
to either manage your own CA or let the module create it automatically.

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
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).

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

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.

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

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

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
