c62c4628d9 networkd-dhcp6: Assign DHCPv6 addresses and prefix lengths
Once IPv6 addresses have been acquired, assign these to the interface
with the prefix lengths taken from the ICMPv6 Router Advertisement
handling code. The preferred and valid IPv6 address lifetimes are
handed to the kernel which will clean up them if not renewed in time.

When a prefix announced via Router Advertisements expires, find all
addresses that match that prefix and update the address to have a
prefix length of 128 causing the prefix to be off-link.

99af546d0e test-icmp6-nd: Add test cases for prefixes
Add test cases that feeds an Router Advertisement to the ICMPv6 code
and verify that the correct prefix lengths are returned given an IPv6
address.

Enhance the prefix verification test by adding a shorter prefix and
check that the intended prefix lengths are now updated.

d77bde34cf sd-icmp6-nd: Parse ICMPv6 prefix information
Save each new onlink IPv6 prefix and attach an expiry timer to it.
If the prefixes overlap, take the shorter prefix and write a debug
message about the event. Once the prefix is resent in a Router
Advertisement, update the timer. Add a new event for the expiring
prefix.

Add two helper functions, one for returning a prefix length given a
Router Advertisement and the other for generic prefix matching given
an IPv6 prefix and address.

09667885ba sd-icmp6-nd: Update Router Advertisement handling
As the IPv6 prefixes are needed, update the ICMPv6 Router Advertisement
code to dynamically allocate a suitably sized buffer. Iterate through
the ICMPv6 options one by one returning error if the option length is
too big to fit the buffer.

e7504d9547 sd-dhcp6-lease: Revise address iteration functions

second one fetches addresses one by one.

The test case is also updated.

10bc4cd469 build-sys: unbundle unifont
We should prefer the unifont.hex file from the system, instead of our
own. Upstream has made a few releases since our version was included,
and we should follow upstream changes. But adding 2.6MB to our source
repo every time upstream releases is not nice.

4a84f3e614 TODO: remove laccess conversion
I looked over all access invocations, and I think are using access()
correctly. Accepting dangling symlinks makes sense only in special
circumstances.

So far we do not allow "flag" files like "/fastboot" to be dangling
symlinks. We could, but I don't see a reason to.

7e26029ff3 timesyncd: set RLIMIT_NPROC to 2
This way timesyncd cannot be used to fork().

Note that it generally is not safe to use RLIMIT_NPROC, since it breaks
running the same daemon in multiple containers if they do not use user
namespacing. However, timesyncd is excepted from running in a container
anyway, hence it is safe in this case.

6b321a7901 system-update-generator: accept a dangling symlink
The offline update mechanism is explicitly designed to work with a
separate /var. systemd-update-generator is supposed to run early,
before filesystems are mounted, so it cannot check if the
/system-update symlink actually points to anything.

The update is run *after* filesystems are mounted, so it should be
able to access the target of the symlink without trouble.

b381de4197 sd-bus: change serialization of kdbus messages to qualify in their entirety as gvariant objects
Previously, we only minimally altered the dbus1 framing for kdbus, and
while the header and its fields where compliant Gvariant objects, and so
was the body, the entire message together was not.

As result of discussions with Ryan Lortie this is now changed, so that
the messages in there entirely are fully compliant GVariants. This
follows the framing description described here:

https://wiki.gnome.org/Projects/GLib/GDBus/Version2

Note that this change changes the framing of *all* messages sent via
kdbus, this means you have to reboot your kdbus system, after compiling
and installing this new version.

ebf31a1f58 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.

df99a9ef5b 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.

36a03ca2a8 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...

874d3404cb 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.
