Moritz Maxeiner 407a770161 Rewrite as a pre-boot authentication module (mostly) comforming to the design specification of
'YubiKey Integration for Full Disk Encryption Pre-Boot Authentication (Copyright) Yubico, 2011 Version: 1.1'.

Used binaries:
  * uuidgen - for generation of random sequence numbers
  * ykchalresp - for challenging a Yubikey
  * ykinfo - to check if a Yubikey is plugged in at boot (fallback to passphrase authentication otherwise)
  * openssl - for calculation of SHA-1, HMAC-SHA-1, as well as AES-256-CTR (de/en)cryption

Main differences to the specification mentioned above:
  * No user management (yet), only one password+yubikey per LUKS device
  * SHA-512 instead of CRC-16 for checksum

Main differences to the previous implementation:
  * Instead of changing the key slot of the LUKS device each boot,
    the actual key for the LUKS device will be encrypted itself
  * Since the response for the new challenge is now calculated
    locally with openssl, the MITM-USB-attack with which previously
    an attacker could obtain the new response (that was used as the new
    encryption key for the LUKS device) by listening to the
    Yubikey has ideally become useless (as long as uuidgen can
    successfuly generate new random sequence numbers).

Remarks:
  * This is not downwards compatible to the previous implementation

Eelco Dolstra 1b5e860f65 Make /etc/localtime a direct symlink to the zoneinfo file
Some programs (notably the Java Runtime Environment) expect to be able
to extract the name of the time zone from the target of the
/etc/localtime symlink.  That doesn't work if /etc/localtime is a
symlink to /etc/static/localtime.  So make it a direct symlink.

Song Wenwu c4885173b6 systemd: add services.journald.extraConfig option 2013-11-30 22:42:01 +01:00
Eelco Dolstra 9ee30cd9b5 Add support for lightweight NixOS containers
You can now say:

  systemd.containers.foo.config =
    { services.openssh.enable = true;
      services.openssh.ports = [ 2022 ];
      users.extraUsers.root.openssh.authorizedKeys.keys = [ "ssh-dss ..." ];
    };

which defines a NixOS instance with the given configuration running
inside a lightweight container.

You can also manage the configuration of the container independently
from the host:

  systemd.containers.foo.path = "/nix/var/nix/profiles/containers/foo";

where "path" is a NixOS system profile.  It can be created/updated by
doing:

  $ nix-env --set -p /nix/var/nix/profiles/containers/foo \
      -f '<nixos>' -A system -I nixos-config=foo.nix

The container configuration (foo.nix) should define

  boot.isContainer = true;

to optimise away the building of a kernel and initrd.  This is done
automatically when using the "config" route.

On the host, a lightweight container appears as the service
"container-<name>.service".  The container is like a regular NixOS
(virtual) machine, except that it doesn't have its own kernel.  It has
its own root file system (by default /var/lib/containers/<name>), but
shares the Nix store of the host (as a read-only bind mount).  It also
has access to the network devices of the host.

Currently, if the configuration of the container changes, running
"nixos-rebuild switch" on the host will cause the container to be
rebooted.  In the future we may want to send some message to the
container so that it can activate the new container configuration
without rebooting.

Containers are not perfectly isolated yet.  In particular, the host's
/sys/fs/cgroup is mounted (writable!) in the guest.

Eelco Dolstra 0e333688ce Big cleanup of the NixOS module system
The major changes are:

* The evaluation is now driven by the declared options.  In
  particular, this fixes the long-standing problem with lack of
  laziness of disabled option definitions.  Thus, a configuration like

    config = mkIf false {
      environment.systemPackages = throw "bla";
    };

  will now evaluate without throwing an error.  This also improves
  performance since we're not evaluating unused option definitions.

* The implementation of properties is greatly simplified.

* There is a new type constructor "submodule" that replaces
  "optionSet".  Unlike "optionSet", "submodule" gets its option
  declarations as an argument, making it more like "listOf" and other
  type constructors.  A typical use is:

    foo = mkOption {
      type = type.attrsOf (type.submodule (
        { config, ... }:
        { bar = mkOption { ... };
          xyzzy = mkOption { ... };
        }));
    };

  Existing uses of "optionSet" are automatically mapped to
  "submodule".

* Modules are now checked for unsupported attributes: you get an error
  if a module contains an attribute other than "config", "options" or
  "imports".

* The new implementation is faster and uses much less memory.
