Vladimír Čunát 02cb604fd6 initrd.availableKernelModules: add support for keyboards
As explained in #2169, some keyboards need special drivers,
so these are always added, both on installation and normal systems.

Eelco Dolstra 1a1442db74 Don't restart systemd-journal-flush
It only needs to be started during boot. Starting it at other times
shouldn't hurt, except that if systemd-journald is restarting at the
same time, the latter might not have a SIGUSR1 signal handler
installed yet, so it might be killed by systemd-journal-flush. (At
least that's my theory about the dead systemd-journald instances in
the build farm...)

Eelco Dolstra 3b2609deec Don't restart systemd-remount-fs
It's only needed during early boot (in fact, it's probably not needed

of the root file system.

Eelco Dolstra bddd10d75c switch-to-configuration: Don't restart instances of user@.service
Restarting user@ instances is bad because it causes all user services

switch-to-configuration restart user units in a fine-grained way, but
for now we should just ignore user systemd instances.

Eelco Dolstra 6eaced3582 Don't mount /sys/fs/fuse/connections and /sys/kernel/config
These fail to mount if you don't have the appropriate kernel support,
and this confuses NixOps' ‘check’ command. We should teach NixOps not
to complain about non-essential mount points, but in the meantime it's
better to turn them off.

Eelco Dolstra e34a1589fe Add support for user units
With ‘systemd.user.units’ and ‘systemd.user.services’, you can specify
units used by per-user systemd instances.  For example,

  systemd.user.services.foo =
    { description = "foo";
      wantedBy = [ "default.target" ];
      serviceConfig.ExecStart = "${pkgs.foo}/bin/foo";
    };

declares a unit ‘foo.service’ that gets started automatically when the
user systemd instance starts, and is stopped when the user systemd
instance stops.

Note that there is at most one systemd instance per user: it's created
when a user logs in and there is no systemd instance for that user
yet, and it's removed when the user fully logs out (i.e. has no
sessions anymore). So if you're simultaneously logged in via X11 and a
virtual console, you get only one copy of foo.

Eelco Dolstra 179acfb664 Allow upstream systemd units to be extended
If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.

This makes the baseUnit option unnecessary, so I've removed it.

appropriate cleanup rules (which we don't have by default).

William A. Kennington III eda854d50f systemd: Add an assertion to guarantee oneshot units do not have restart set
This prevents insidious errors once systemd begins handling the unit. If
the unit is loaded at boot, any errors of this nature are logged to the
console before the journal service is running. This makes it very hard
to diagnose the issue. Therefore, this assertion helps guarantee the
mistake is not made.

Eelco Dolstra 29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

systemd: Add support for path units.
This allows to define systemd.path(5) units, for example like this:

{
  systemd = let
    description = "Set Key Permissions for xyz.key";
  in {
    paths.set-key-perms = {
      inherit description;
      before = [ "network.target" ];
      wantedBy = [ "multi-user.target" ];
      pathConfig.PathChanged = "/run/keys/xyz.key";
    };

    services.set-key-perms = {
      inherit description;
      serviceConfig.Type = "oneshot";
      script = "chown myspecialkeyuser /run/keys/xyz.key";
    };
  };
}

The example here is actually useful in order to set permissions for the
NixOps keys target to ensure those permisisons aren't reset whenever the
key file is reuploaded.

Eelco Dolstra 691c0cd72e systemd: Allow customisation of upstream units
You can now say:

  systemd.services.foo.baseUnit = "${pkgs.foo}/.../foo.service";

This will cause NixOS' generated foo.service file to include
foo.service from the foo package.  You can then apply local
customization in the usual way:

  systemd.services.foo.serviceConfig.MemoryLimit = "512M";

Note however that overriding options in the original unit may not
work.  For instance, you cannot override ExecStart.

It's also possible to customize instances of template units:

  systemd.services."getty@tty4" =
    { baseUnit = "/etc/systemd/system/getty@.service";
      serviceConfig.MemoryLimit = "512M";
    };

This replaces the unit options linkTarget (which didn't allow
customisation) and extraConfig (which did allow customisation, but in
a non-standard way).

Moritz Maxeiner 09f9af17b4 Update to the Yubikey PBA
Security-relevant changes:
 * No (salted) passphrase hash send to the yubikey, only hash of the salt (as it was in the original implementation).
 * Derive $k_luks with PBKDF2 from the yubikey $response (as the PBKDF2 salt) and the passphrase $k_user
   (as the PBKDF2 password), so that if two-factor authentication is enabled
   (a) a USB-MITM attack on the yubikey itself is not enough to break the system
   (b) the potentially low-entropy $k_user is better protected against brute-force attacks
 * Instead of using uuidgen, gather the salt (previously random uuid / uuid_r) directly from /dev/random.
 * Length of the new salt in byte added as the parameter "saltLength", defaults to 16 byte.
   Note: Length of the challenge is 64 byte, so saltLength > 64 may have no benefit over saltLengh = 64.
 * Length of $k_luks derived with PBKDF2 in byte added as the parameter "keyLength", defaults to 64 byte.
   Example: For a luks device with a 512-bit key, keyLength should be 64.
 * Increase of the PBKDF2 iteration count per successful authentication added as the
   parameter "iterationStep", defaults to 0.

Other changes:
 * Add optional grace period before trying to find the yubikey, defaults to 2 seconds.

Full overview of the yubikey authentication process:

  (1) Read $salt and $iterations from unencrypted device (UD).
  (2) Calculate the $challenge from the $salt with a hash function.
      Chosen instantiation: SHA-512($salt).
  (3) Challenge the yubikey with the $challenge and receive the $response.
  (4) Repeat three times:
    (a) Prompt for the passphrase $k_user.
    (b) Derive the key $k_luks for the luks device with a key derivation function from $k_user and $response.
        Chosen instantiation: PBKDF2(HMAC-SHA-512, $k_user, $response, $iterations, keyLength).
    (c) Try to open the luks device with $k_luks and escape loop (4) only on success.
  (5) Proceed only if luks device was opened successfully, fail otherwise.

  (6) Gather $new_salt from a cryptographically secure pseudorandom number generator
      Chosen instantiation: /dev/random
  (7) Calculate the $new_challenge from the $new_salt with the same hash function as (2).
  (8) Challenge the yubikey with the $new_challenge and receive the $new_response.
  (9) Derive the new key $new_k_luks for the luks device in the same manner as in (4) (b),
      but with more iterations as given by iterationStep.
 (10) Try to change the luks device's key $k_luks to $new_k_luks.
 (11) If (10) was successful, write the $new_salt and the $new_iterations to the UD.
      Note: $new_iterations = $iterations + iterationStep

Known (software) attack vectors:

 * A MITM attack on the keyboard can recover $k_user. This, combined with a USB-MITM
   attack on the yubikey for the $response (1) or the $new_response (2) will result in
   (1) $k_luks being recovered,
   (2) $new_k_luks being recovered.
 * Any attacker with access to the RAM state of stage-1 at mid- or post-authentication
   can recover $k_user, $k_luks, and  $new_k_luks
 * If an attacker has recovered $response or $new_response, he can perform a brute-force
   attack on $k_user with it without the Yubikey needing to be present (using cryptsetup's
   "luksOpen --verify-passphrase" oracle. He could even make a copy of the luks device's
   luks header and run the brute-force attack without further access to the system.
 * A USB-MITM attack on the yubikey will allow an attacker to attempt to brute-force
   the yubikey's internal key ("shared secret") without it needing to be present anymore.

Moritz Maxeiner 8e74e1fded Replace the current Yubikey PBA implementation with the previous one.
Rationale:
  * The main reason for choosing to implement the PBA in accordance
    with the Yubico documentation was to prevent a MITM-USB-attack
    successfully recovering the new LUKS key.
  * However, a MITM-USB-attacker can read user id and password when
    they were entered for PBA, which allows him to recover the new
    challenge after the PBA is complete, with which he can challenge
    the Yubikey, decrypt the new AES blob and recover the LUKS key.
  * Additionally, since the Yubikey shared secret is stored in the
    same AES blob, after such an attack not only is the LUKS device
    compromised, the Yubikey is as well, since the shared secret
    has also been recovered by the attacker.
  * Furthermore, with this method an attacker could also bruteforce
    the AES blob, if he has access to the unencrypted device, which
    would again compromise the Yubikey, should he be successful.
  * Finally, with this method, once the LUKS key has been recovered
    once, the encryption is permanently broken, while with the previous
    system, the LUKS key itself it changed at every successful boot,
    so recovering it once will not necessarily result in a permanent
    breakage and will also not compromise the Yubikey itself (since
    its secret is never stored anywhere but on the Yubikey itself).

Summary:
The current implementation opens up up vulnerability to brute-forcing
the AES blob, while retaining the current MITM-USB attack, additionally
making the consequences of this attack permanent and extending it to
the Yubikey itself.

Moritz Maxeiner e96f58ef5c Implement muli-user authentication for yubikey pba, i.e. multiple users can now share a single luks keyslot.
This is achieved by having multiple lines per storage file, one for each user (if the feature is enabled); each of these
lines has the same format as would be the case for the userless authentication, except that they are prepended with a
SHA-512 of the user's id.
