90558f3158 logind: add a new UserTasksMax= setting to logind.conf
This new setting configures the TasksMax= field for the slice objects we
create for each user.

This alters logind to create the slice unit as transient unit explicitly
instead of relying on implicit generation of slice units by simply
starting them. This also enables us to set a friendly description for
slice units that way.

eb55ec9fec util-lib: when parsing time values, accept "M" as short for "month"
nginx defines an uppercase "M" that way (in contrast to the lowercase
"m" for "minute"), and it sounds like an OK logic to follow, so that we
understand a true superset of time values nginx understands.

765afd5c4d networkd: stop managing per-interface IP forwarding settings
As it turns out the kernel does not support per-interface IPv6 packet
forwarding controls (unlike as it does for IPv4), but only supports a
global option (#1597). Also, the current per-interface management of the
setting isn't really useful, as you want it to propagate to at least one
more interface than the one you configure it on. This created much grief
(#1411, #1808).

Hence, let's roll this logic back and simplify this again, so that we
can expose the same behaviour on IPv4 and IPv6 and things start to work
automatically again for most folks: if a network with this setting set
is set up we propagate the setting into the global setting, but this is
strictly one-way: we never reset it again, and we do nothing for network
interfaces where this setting is not enabled.

Fixes: #1808, #1597.

d68e2e59b3 networkd: rearrange checks when to write something into sysctl a bit
Move check whether ipv6 is available into link_ipv6_privacy_extensions()
to keep it as internal and early as possible.

Always check if there's a network attached to a link before we apply
sysctls. We do this for most of the sysctl functions already, with this
change we do it for all.

eb3da9012f util-lib: optionally, when writing a string to a file, verify string on failure
With this change, the idiom:

    r = write_string_file(p, buf, 0);
    if (r < 0) {
           if (verify_one_line_file(p, buf) > 0)
                   r = 0;
    }

gets reduced to:

    r = write_string_file(p, buf, WRITE_STRING_FILE_VERIFY_ON_FAILURE);

i.e. when writing the string fails and the new flag
WRITE_STRING_FILE_VERIFY_ON_FAILURE is specified we'll not return a
failure immediately, but check the contents of the file. If it matches
what we wanted to write we suppress the error and exit cleanly.

e7eb5a8d88 udev/path_id: improve and enhance bus detection for Linux on z Systems
Improve and enhance the path_id udev builtin to correctly handle bus'
available on Linux on z Systems (s390).

Previously, the CCW bus and, in particular, any FCP devices on it, have
been treated separately.  This commit integrates the CCW bus into the
device chain loop.  FCP devices and their associated SCSI disks are now
handled through the common SCSI handling functions in path_id.

This implies also a change in the naming of the symbolic links created
by udev.  So any backports of this commit to existing Linux distribution
must be done with care.  If a backport is required, a udev rule must be
created to also create the "old-style" symbolic links.

Apart from the CCW bus, this commit adds bus support for the:

- ccwgroup bus which manages network devices, and
- ap bus which manages cryptographic adapters
- iucv bus which manages IUCV devices on z/VM

5fd534d919 generator: order initrd fsck-root after local-fs-pre
The initrd version of systemd-fsck-root.service must wait for
local-fs-pre.target just like systemd-fsck@.service to prevent
modifications to the filesystem prior to resuming from hibernation.
As-is my laptop routinely fails to resume due to fsck errors. The rest
of the time it is probably silently corrupting the filesystem.

Unlike normal boot, in the initrd systemd-fsck-root.service has no
special significance so it needs to be kept in sync with
systemd-fsck@.service. The name systemd-fsck-root.service is only used
to preserve state across switch-root.

f6d6bad146 nspawn: add new --network-veth-extra= switch for defining additional veth links
The new switch operates like --network-veth, but may be specified
multiple times (to define multiple link pairs) and allows flexible
definition of the interface names.

This is an independent reimplementation of #1678, but defines different
semantics, keeping the behaviour completely independent of
--network-veth. It also comes will full hook-up for .nspawn files, and
the matching documentation.

f32b43bda4 core: remove support for RequiresOverridable= and RequisiteOverridable=
As discussed at systemd.conf 2015 and on also raised on the ML:

http://lists.freedesktop.org/archives/systemd-devel/2015-November/034880.html

This removes the two XyzOverridable= unit dependencies, that were
basically never used, and do not enhance user experience in any way.
Most folks looking for the functionality this provides probably opt for
the "ignore-dependencies" job mode, and that's probably a good idea.

Hence, let's simplify systemd's dependency engine and remove these two
dependency types (and their inverses).

The unit file parser and the dbus property parser will now redirect
the settings/properties to result in an equivalent non-overridable
dependency. In the case of the unit file parser we generate a warning,
to inform the user.

The dbus properties for this unit type stay available on the unit
objects, but they are now hidden from usual introspection and will
always return the empty list when queried.

This should provide enough compatibility for the few unit files that
actually ever made use of this.

79413b673b core: simplify handling of %u, %U, %s and %h unit file specifiers
Previously, the %u, %U, %s and %h specifiers would resolve to the user
name, numeric user ID, shell and home directory of the user configured
in the User= setting of a unit file, or the user of the manager instance
if no User= setting was configured. That at least was the theory. In
real-life this was not ever actually useful:

- For the systemd --user instance it made no sense to ever set User=,
  since the instance runs in user context after all, and hence the
  privileges to change user IDs don't even exist. The four specifiers
  were actually not useful at all in this case.

- For the systemd --system instance we did not allow any resolving that
  would require NSS. Hence, %s and %h were not supported, unless
  User=root was set, in which case they would be hardcoded to /bin/sh
  and /root, to avoid NSS. Then, %u would actually resolve to whatever
  was set with User=, but %U would only resolve to the numeric UID of
  that setting if the User= was specified in numeric form, or happened
  to be root (in which case 0 was hardcoded as mapping). Two of the
  specifiers are entirely useless in this case, one is realistically
  also useless, and one is pretty pointless.

- Resolving of these settings would only happen if User= was actually
  set *before* the specifiers where resolved. This behaviour was
  undocumented and is really ugly, as specifiers should actually be
  considered something that applies to the whole file equally,
  independently of order...

With this change, %u, %U, %s and %h are drastically simplified: they now
always refer to the user that is running the service instance, and the
user configured in the unit file is irrelevant. For the system instance
of systemd this means they always resolve to "root", "0", "/bin/sh" and
"/root", thus avoiding NSS. For the user instance, to the data for the
specific user.

The new behaviour is identical to the old behaviour in all --user cases
and for all units that have no User= set (or set to "0" or "root").

0ec0deaa30 install: follow unit file symlinks in /usr, but not /etc when looking for [Install] data
Some distributions use alias unit files via symlinks in /usr to cover
for legacy service names. With this change we'll allow "systemctl
enable" on such aliases.

Previously, our rule was that symlinks are user configuration that
"systemctl enable" + "systemctl disable" creates and removes, while unit
files is where the instructions to do so are store. As a result of the
rule we'd never read install information through symlinks, since that
would mix enablement state with installation instructions.

Now, the new rule is that only symlinks inside of /etc are
configuration. Unit files, and symlinks in /usr are now valid for
installation instructions.

This patch is quite a rework of the whole install logic, and makes the
following addional changes:

- Adds a complete test "test-instal-root" that tests the install logic
  pretty comprehensively.

- Never uses canonicalize_file_name(), because that's incompatible with
  operation relative to a specific root directory.

- unit_file_get_state() is reworked to return a proper error, and
  returns the state in a call-by-ref parameter. This cleans up confusion
  between the enum type and errno-like errors.

- The new logic puts a limit on how long to follow unit file symlinks:
  it will do so only for 64 steps at max.

- The InstallContext object's fields are renamed to will_process and
  has_processed (will_install and has_installed) since they are also
  used for deinstallation and all kinds of other operations.

- The root directory is always verified before use.

- install.c is reordered to place the exported functions together.

- Stricter rules are followed when traversing symlinks: the unit suffix
  must say identical, and it's not allowed to link between regular units
  and templated units.

- Various modernizations

- The "invalid" unit file state has been renamed to "bad", in order to
  avoid confusion between UNIT_FILE_INVALID and
  _UNIT_FILE_STATE_INVALID. Given that the state should normally not be
  seen and is not documented this should not be a problematic change.
  The new name is now documented however.
