nixos/nsd: symlink conf file to /etc/nsd
We remove the configFile build flag override in the NixOS module.

Instead of embedding the conf file link to the binaries, we symlink it
to /etc/nsd/nsd.nix, the hardcoded config file location for the
various CLI nsd utilities.

This config file build option override is triggerring a nsd rebuild
for each configuration change. This prevent us to use the nixos cache
in many cases.

nixos/treewide: drop dependencies to keys.target
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).

As described in the NixOps manual[1], dependencies to keys should be
defined like this now:

``` nix
{
  systemd.services.myservice = {
    after = [ "secret-key.service" ];
    wants = [ "secret-key.service" ];
  };
}
```

However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.

nixos/nsd: Improve checking for empty dnssec zones
While at it (see previous commit), using attrNames in combination with
length is a bit verbose for checking whether the filtered attribute set
is empty, so let's just compare it against an empty attribute set.

nixos/nsd: Don't override bind via nixpkgs.config
When generating values for the services.nsd.zones attribute using values
from pkgs, we'll run into an infinite recursion because the nsd module
has a condition on the top-level definition of nixpkgs.config.

While it would work to push the definition a few levels down, it will
still only work if we don't use bind tools for generating zones.

As far as I could see, Python support for BIND seems to be only needed
for the dnssec-* tools, so instead of using nixpkgs.config, we now
directly override pkgs.bind instead of globally in nixpkgs.

To illustrate the problem with a small test case, instantiating the
following Nix expression from the nixpkgs source root will cause the
mentioned infinite recursion:

  (import ./nixos {
    configuration = { lib, pkgs, ... }: {
      services.nsd.enable = true;
      services.nsd.zones = import (pkgs.writeText "foo.nix" ''
        { "foo.".data = "xyz";
          "foo.".dnssec = true;
        }
      '');
    };
  }).vm

With this change, generating zones via import-from-derivation is now
possible again.

nixos/nsd: Allow to configure root zone
When trying to run NSD to serve the root zone, one gets the following
error message:

error: illegal name: '.'

This is because the name of the zone is used as the derivation name for
building the zone file. However, Nix doesn't allow derivation names
starting with a period.

So whenever the zone is "." now, the file name generated is "root"
instead of ".".

I also added an assertion that makes sure the user sets
services.nsd.rootServer, otherwise NSD will fail at runtime because it
prevents serving the root zone without an explicit compile-time option.

Tested this by adding a root zone to the "nsd" NixOS VM test.

553a3295c1 nsd: 4.1.9 -> 4.1.12
4.1.12
======

Bugfixes
--------

Fix malformed edns query assertion failure, reported by Michal Kepien (NASK).

4.1.11
======

Features
--------

* When tcp is more than half full, use short timeout for tcp session.
* Patch for {max,min}-{refresh,retry}-time from YAMAGUCHI Takanori.
* Fix #790: size-limit-xfr can stop NSD from downloading infinite zone transfer data size, from Toshifumi Sakaguchi. Fixes CVE-2016-6173 JVN#63359718 JPCERT#91251865.

Bugfixes
--------

* Fix build without IPv6, patch from Zdenek Kaspar.
* Fix #783: Trying to run a root server without having configured it silently gives wrong answers.
* Fix #782: Serve DS record but parent zone has no NS record.
* Fix nsec3 missing for nsec3 signed parent and child for DS at zonecut.

4.1.10
======

Features
--------

* ip-freebind: yesno option in nsd.conf sets IP_FREEBIND socket option for Linux, binds to interfaces and addresses that are down.
* NSD includes AAAA before A for queries over IPV6 (in delegations). And TC is set if no glue can be provided with a delegation because of packet size.
* print notice that nsd is starting before taking off.

Bugfixes
--------

* Fix for openssl 1.1.0, HMAC_CTX size not exported from openssl.
* Fix #751: NSD fails to occlude names below a DNAME.
* If set without nsd.db print "" as the default in the man pages.
* Fix #755: NSD spins after a zone update and a lot of TCP queries.
* Fix for NSEC3 with zone signed without exact match for empty nonterminals, the answer for that domain gets closest encloser.
* #772 Document that recvmmsg has IPv6 problems on some linux kernels.

4.1.9
=====

Bugfixes
--------

* Change the nsd.db file version because of nanosecond precision fix.
