When a uevent is received during the relevant interface is in
LINK_STATE_PENDING, then the interface may be initialized twice.
To prevent that, this introduces LINK_STATE_INITIALIZED.
kernel-4.15's if_ether.h has a bug that the header does not provide
'struct ethhdr'. The bug is introduced by
6926e041a8920c8ec27e4e155efa760aa01551fd (4.15-rc8)
and fixed by da360299b6734135a5f66d7db458dcc7801c826a (4.16-rc3).
This makes systemd built with kernel-4.15 headers.
Fixes#12319.
The L2TP_ATTR_UDP_ZERO_CSUM6_{TX,RX} attributes are introduced by
6b649feafe10b293f4bd5a74aca95faf625ae525, which is included in
kernel-3.16. To support older kernel, let's import the header.
Fixes#12300.
Now linux/in.h has better conflict detection with glibc's
netinet/in.h. So, let's import the headers.
Note that our code already have many workarounds for the conflict,
but in this commit does not drop them. Let's do that in the later
commits if this really helps.
tmp.conf was dealing with 2 different kind of paths: one dealing with general
temporary paths such as /var/tmp and /tmp and the other one dealing with
temporary directories owned by systemd.
If for example a user wants to adjust the age argument of the general paths
only, he had to overload the whole file which is cumbersome and error prone
since any future changes in tmp.conf shipped by systemd will be lost.
So this patch splits out tmp.conf so the systemd directories are dealt
separately in a dedicated conf file. It's named "systemd-tmp.conf" based on the
naming recommendation made in tmpfiles.d man page.
In practice it shouldn't cause any regression since it's very unlikely that
users override paths owned by systemd.
With gcc-9.0.1-0.10.fc30.x86_64:
../src/network/netdev/macsec.c: In function ‘config_parse_macsec_port’:
../src/network/netdev/macsec.c:584:24: warning: taking address of packed member of ‘struct <anonymous>’ may result in an unaligned pointer value [-Waddress-of-packed-member]

../src/network/netdev/macsec.c:592:24: warning: taking address of packed member of ‘struct <anonymous>’ may result in an unaligned pointer value [-Waddress-of-packed-member]
592 | dest = &b->sci.port;

(The alignment was probably OK, but it's nicer to avoid the warning anyway.)
When shooting down a service with SIGABRT the user might want to have a
much longer stop timeout than on regular stops/shutdowns. Especially in
the face of short stop timeouts the time might not be sufficient to
write huge core dumps before the service is killed.
This commit adds a dedicated (Default)TimeoutAbortSec= timer that is
used when stopping a service via SIGABRT. In all other cases the
existing TimeoutStopSec= is used. The timer value is unset by default
to skip the special handling and use TimeoutStopSec= for state
'stop-watchdog' to keep the old behaviour.
If the service is in state 'stop-watchdog' and the service should be
stopped explicitly we still go to 'stop-sigterm' and re-apply the usual
TimeoutStopSec= timeout.

I think improve readability or consistency.]

In cgroup v2 we have protection tunables -- currently MemoryLow and
MemoryMin (there will be more in future for other resources, too). The
design of these protection tunables requires not only intermediate
cgroups to propagate protections, but also the units at the leaf of that
resource's operation to accept it (by setting MemoryLow or MemoryMin).
This makes sense from an low-level API design perspective, but it's a
good idea to also have a higher-level abstraction that can, by default,
propagate these resources to children recursively. In this patch, this
happens by having descendants set memory.low to N if their ancestor has
DefaultMemoryLow=N -- assuming they don't set a separate MemoryLow
value.
Any affected unit can opt out of this propagation by manually setting
`MemoryLow` to some value in its unit configuration. A unit can also
stop further propagation by setting `DefaultMemoryLow=` with no
argument. This removes further propagation in the subtree, but has no
effect on the unit itself (for that, use `MemoryLow=0`).
Our use case in production is simplifying the configuration of machines
which heavily rely on memory protection tunables, but currently require
tweaking a huge number of unit files to make that a reality. This
directive makes that significantly less fragile, and decreases the risk
of misconfiguration.
After this patch is merged, I will implement DefaultMemoryMin= using the
same principles.
