tmpfiles: use casts instead of warning suppression
This warning got its own name only in gcc5, so the suppression does
not work in gcc4, and generates a warning of its own. Use a cast,
which is ugly too, but less so.

udev: event - move renaming of udev_device to libudev
This is not exposed in the public API. We want to simplify the internal libudev-device API as much as possible
so that it will be simpler to rip the whole thing out in the future.
tmpfiles: do not bump access times of directories we are cleaning up
Both plain opendir() and glob() will bump access time. Privileged
option O_NOATIME can be used to prevent the access time from being
updated. We already used it for subdirectories of the directories
which we were cleaning up. But for the directories specified directly
in the config files, we wouldn't do that. This means that,
paradoxically, our own temporary directories for PrivateTmp would stay
around forever, as long as one let systemd-tmpfiles-clean.service run
regularly, because they had their own glob patterns specified.
systemd-tmpfiles can be used by users, but it can be quite hard to
figure out the logic it follows, especially since the logic is in some
places rather torturous. Hopefuly this will make it easier for users
to understand what is happening.
Current systemd requires kernel >= 3.7 per the README file
but CONFIG_USB_DEVICEFS disappeared from the kernel in
upstream commit fb28d58b72aa9215b26f1d5478462af394a4d253
(kernel 3.5-rc1)
resolved: when rereading /etc/resolv.conf, always start using first DNS server again
Previously we tried to stick to a DNS server as long as it is available.
When /etc/resolv.conf changed, and the old DNS server we used was still
in there we'd continue to use it, even if it was at the end of the list.
With this change we'll now always start with the first DNS server in the
list again.
Rationale: certain network managing implementations (notably
NetworkManager) when connected to a VPN place both the VPN DNS server as
well as the local DNS server in /etc/resolv.conf. If we used the local
one before we would thus continue to use the local one, making VPN names
unresolvable. NetworkManager really should be fixed to only place the
VPN DNS servers in the file, but with this commit things are at least
similarly bad as they used to be...

systemctl: bugfix for systemctl reboot command with argument
According to systemctl man page, 'systemctl reboot [arg]' should work
without any errors. However, it does not work because of 'Invalid number
of arguments' error, except for 'reboot [arg]'. This patch fixes the bug
so that both of commands work in exactly the same way.
core,shutdown: don't bother with unmounting any mounts below /sys, /proc, /dev when shutting down
After all, mounts below these directories are pretty much guaranteed to
be virtual, and it's hence unnecessary to unmount them during shutdown.
Moreover, in less-priviliged containers we might lack the rights to
unmount them, hence don't even try.
nspawn: mount /tmp in the container, don't leave this to the container's init
We really want /tmp to be properly mounted, especially in containers
that lack CAP_SYS_ADMIN or that are not fully booted up and only get a
shell, hence let's do so in nspawn already.
importd: when listing transfers, show progress percentage
With this change the pull protocol implementation processes will pass
progress data to importd which then passes this information on via the
bus. We use sd_notify() as generic transport for this communication,
making importd listen to them, while matching the incoming messages to
the right transfer.

sd-dhcp-client: use RFC4361-complient ClientID by default
In addition to the benefits listed in the RFC, this allows DHCP to work also in
case several interfaces share the same MAC address on the same link (IPVLAN).
Note that this will make the ClientID (so probably the assigned IP address)
change on upgrades. If it is desired to avoid that we would have to remember and
write back the ID (which the library supports, but networkd currently does not).

tmpfiles: make t and a globby, add their recursive versions T and A
For types which adapt existing files it is generally more useful to accept
globs.
In analogy to z and Z, add recursive versions using uppercase letters.
Technically, making a accept globs is backwards incompatible, but in
practice it probably isn't yet widely used and we can assume that most
people don't create files with wildcards in names.
Functions which are used as callbacks, but not directly on items, are
renamed not to have "item_" prefix.
The data structure used by tmpfiles is changed: instead of hashmaps
mapping {path → Item*} we now have hashmaps containing
{path -> ItemArray}, where ItemArray contains a pointer
to an array of Items.
For current code it doesn't matter much, but when we add new types it
is easier to simply add a new Item for a given path, then to coalesce
multiple lines into one Item.
In the future, this change will also make it possible to remember the
file and line where each Item originates, and use that in reporting
errors. Currently this is not possible, since each Item can be created
from multiple lines.
int[] should not be used as pid_t[], even if happens to be same thing.
Also deduplicating in a quadratic loop right before sorting is unnecessary.
Remove custom greedy_realloc implementation.
import: introduce new mini-daemon systemd-importd, and make machinectl a client to it
The old "systemd-import" binary is now an internal tool. We still use it
as asynchronous backend for systemd-importd. Since the import tool might
require some IO and CPU resources (due to qcow2 explosion, and
decompression), and because we might want to run it with more minimal
priviliges we still keep it around as the worker binary to execute as
child process of importd.
machinectl now has verbs for pulling down images, cancelling them and
listing them.

sysv-generator: Replace Provides: symlinks with real units
Since commit b7e7184 the SysV generator creates symlinks for all "Provides:" in
the LSB header. However, this is too greedy; there are cases where the
creation of a unit .service file fails because of an already existing
symlink with the same name:
- Backup files such as /etc/init.d/foo.bak still have "Provides: foo", and
thus get a foo.service -> foo.bak.service link. foo.bak would not be enabled
in rcN.d/, but we (deliberately) create units for all executables in init.d/
so that a manual "systemctl start" works. If foo.bak is processed before,
the symlink already exists.
- init.d/bar has "Provides: foo", while there also is a real init.d/foo. The
former would create a link foo.service -> bar.service, while the latter
would fail to create the real foo.service.
If we encounter an existing symlink, just remove it before writing a real unit.
Note that two init.d scripts "foo" and "bar" which both provide the same name
"common" already work. The first processed init script wins and creates the
"common.service" symlink, and the second just fails to create the symlink
again. Thus create an additional test case for this to ensure that it keeps
working sensibly.
