Zbigniew Jędrzejewski-Szmek d7ceaf7261 shared/install: provide a nicer error message for invalid WantedBy=/Required= values 
$ build/systemctl --user cat badinstall
 # /home/zbyszek/.config/systemd/user/badinstall.service
[Service]
ExecStart=true

[Install]
WantedBy=asdf

$ build/systemctl --user enable badinstall
Failed to enable unit: "asdf" is not a valid unit name.

Fixes #4209.

Lennart Poettering d0556c55e7 nspawn: fix overlay with automatic temporary tree 
This makes --overlay=+/foobar::/foobar work again, i.e. where the middle
parameter is left out. According to the documentation this is supposed
to generate a temporary writable work place in the midle. But it
apparently never did. Weird.

Lennart Poettering db8728a60c blockdev-util: rework get_block_device() 
Let's open the specified path once, and use the same fd for all lookups.
Also, don't check for btrfs twice.

The behaviour remains unmodified.

Lennart Poettering 6047637645 strv: when growing strv arrays piecemeal actually allocate memory in exponential steps 
Let's improve memory allocation for call such as strv_extend() that just
one item to an strv: these are often called in a loop, where they used
to be very ineffecient, since we'd allocate byte-exact space. With this
change let's improve on that, by allocating exponentially by rounding up
to the next exponent of 2. This way we get GREEDY_REALLOC()-like
behaviour without passing around state.

In fact this should be good enough so that we could replace existing
loops around GREEDY_REALLOC() for strv build-up with plain strv_extend()
and get similar behaviour.

resolved, networkd: don't resolve the user if not root 
If a daemon is not started as root, most likely it also can't create its
directory and let's not try to resolve the user in that case either.

Create /run/systemd/netif/lldp with tmpfiles.d like other netif directories.

This is also very helpful for preparing a RootImage for the daemons as NSS crud
is not needed.

Susant Sahani 3295a461b3 network: introduce ifb (Intermediate Functional Block) 
Intermediate Functional Block

The Intermediate Functional Block (ifb) pseudo network interface acts as a QoS concentrator for multiple different sources of traffic. Packets from or to other interfaces have to be redirected to it using the mirred action in order to be handled, regularly routed traffic will be dropped. This way, a single stack of qdiscs, classes and filters can be shared between multiple interfaces.

Here's a simple example to feed incoming traffic from multiple interfaces through a Stochastic Fairness Queue (sfq):

(1) # modprobe ifb
(2) # ip link set ifb0 up
(3) # tc qdisc add dev ifb0 root sfq
