Thomas Tuegel cc058eff70 kde5_latest: merge all package sets
The three KDE package sets now have circular dependencies between them,
so they can only be built if they are merged into a single package set
during evaluation.

obadz 9be012f0d4 lightdm & xserver service: add ability to spawn more than one X server
- if xserver.tty and/or display are set to null, then don't specify
  them, or the -logfile argument in the xserverArgs
- For lightdm, we set default tty and display to null and we determine
  those at runtime based on arguments passed. This is necessary because
  we run multiple X servers so they can't all be on the same display

nixos/tests: Revert setting min_free_kbytes
This reverts commit 02b568414d.

With a5bc11f and 6353f58 in place, we really don't need this anymore.

After running about 500 VM tests on my Hydra, it still didn't improve
very much.

nixos/qemu-vm: Disable cache for $NIX_DISK_IMAGE
As @domenkozar noted in #10828, cache=writeback seems to do more harm
than good:

https://github.com/NixOS/nixpkgs/issues/10828#issuecomment-164426821

He has tested it using the openstack NixOS tests and found that
cache=none significantly improves startup performance.

nixos/vm-tests: Remove msize mount option
This seems to be the root cause of the random page allocation failures
and @wizeman did a very good job on not only finding the root problem
but also giving a detailed explanation of it in #10828.

Here is an excerpt:

  The problem here is that the kernel is trying to allocate a contiguous
  section of 2^7=128 pages, which is 512 KB. This is way too much:
  kernel pages tend to get fragmented over time and kernel developers
  often go to great lengths to try allocating at most only 1 contiguous
  page at a time whenever they can.

  From the error message, it looks like the culprit is unionfs, but this
  is misleading: unionfs is the name of the userspace process that was
  running when the system ran out of memory, but it wasn't unionfs who
  was allocating the memory: it was the kernel; specifically it was the
  v9fs_dir_readdir_dotl() function, which is the code for handling the
  readdir() function in the 9p filesystem (the filesystem that is used
  to share a directory structure between a qemu host and its VM).

  If you look at the code, here's what it's doing at the moment it tries
  to allocate memory:

    buflen = fid->clnt->msize - P9_IOHDRSZ;

    rdir = v9fs_alloc_rdir_buf(file, buflen);

  If you look into v9fs_alloc_rdir_buf(), you will see that it will try
  to allocate a contiguous buffer of memory (using kzalloc(), which is a
  wrapper around kmalloc()) of size buflen + 8 bytes or so.

  So in reality, this code actually allocates a buffer of size
  proportional to fid->clnt->msize. What is this msize? If you follow
  the definition of the structures, you will see that it's the
  negotiated buffer transfer size between 9p client and 9p server. On
  the client side, it can be controlled with the msize mount option.

  What this all means is that, the reason for running out of memory is
  that the code (which we can't easily change) tries to allocate a
  contiguous buffer of size more or less equal to "negotiated 9p
  protocol buffer size", which seems to be way too big (in our NixOS
  tests, at least).

After that initial finding, @lethalman tested the gnome3 gdm test
without setting the msize parameter at all and it seems to have resolved
the problem.

The reason why I'm committing this without testing against all of the
NixOS VM test is basically that I think we can only go better but not
worse than the current state.

nixos/test-instrumentation: Set vm.min_free_kbytes
We hit page allocation failures a lot at random for VM tests, in case of
my own Hydra when it comes to the installer tests. The reason for this
is that once the memory of the VM gets heavily fragmented the kernel is
unable to allocate new pages.

Setting vm.min_free_kbytes to 16MB forces the kernel to keep a minimum
of 16 MB free.

I've done some testing accross repeated runs of the installer tests with
and without vm.min_free_kbytes set. So accross 30 test runs for each
settings, all of the tests with the option being set passed while 14
tests without that sysctl option triggered page allocation failures.

Sure, running 30 tests is not a guarantee that 16MB is enough, but we'll
see how it turns out in the long run across all VM tests.

Franz Pletz 612781e816 simp_le service: letsencrypt cert auto-renewal
This new service invokes `simp_le` for a defined set of certs on a regular
basis with a systemd timer. `simp_le` is smart enough to handle account
registration, domain validation and renewal on its own. The only thing
required is an existing HTTP server that serves the path
`/.well-known/acme-challenge` from the webroot cert parameter.

Example:

  services.simp_le.certs."foo.example.com" = {
    webroot = "/var/www/challenges";
    extraDomains = [ "www.example.com" ];
    email = "foo@example.com";
    validMin = 2592000;
    renewInterval = "weekly";
  };

Example Nginx vhost:

  services.nginx.appendConfig = ''
    http {
      server {
        server_name _;
        listen 80;
        listen [::]:80;

        location /.well-known/acme-challenge {
          root /var/www/challenges;
        }

        location / {
          return 301 https://$host$request_uri;
        }
      }
    }
  '';
