network: neighbor: Always add neighbors with replace
We were duplicating setting flags for the message and a combination of
NLM_F_APPEND and NLM_F_CREATE which does not make sense. We should have
been using NLM_F_REPLACE and NLM_F_CREATE since the kernel can
dynamically create neighbors prior to us adding an entry. Otherwise, we
can end up with cases where the message will time out after ~25s even

bpf: add socket-bind BPF program code sources
Introduce BPF program compiled from BPF source code in
restricted C - socket-bind.
It addresses feature request [0].
The goal is to allow systemd services to bind(2) only to a predefined set
of ports. This prevents assigning socket address with unallowed port
to a socket and creating servers listening on that port.
This compliments firewalling feature presenting in systemd:
whereas cgroup/{egress|ingress} hooks act on packets, this doesn't
protect from untrusted service or payload hijacking an important port.
While ports in 0-1023 range are restricted to root only, 1024-65535
range is not protected by any mean.
Performance is another aspect of socket_bind feature since per-packet
cost can be eliminated for some port-based filtering policies.
The feature is implemented with cgroup/bind{4|6} hooks [1].
In contrast to the present systemd approach using raw bpf instructions,
this program is compiled from sources. Stretch goal is to
make bpf ecosystem in systemd more friendly for developer and to clear
path for more BPF programs.

It's OK to specify the root dir as target directory when copying

Let's address that by moving the call further down into the loop, when
we made sure that the target dir doesn't exist yet (the root dir always
exists, hence this check is sufficient).
Moreover, in the branch for copying regular files, also move the calls
down, and generate friendly error messages in case people try to
overwrite dirs with regular files (and the root dir is just a special

When we copy files into the freshly formatted file system, the mount

journald: Retry if posix_fallocate returned -1 (EINTR)
On some conditions (particularly when mobile CPUs are going to sleep),
the posix_fallocate(), which is called when a new journal file is allocated,
can return -1 (EINTR). This is counted as a fatal error. So the journald
closes both old and journals, and simply throwing away further incoming
events, because of no log files open.
Introduce posix_fallocate_loop() that restarts the function in the case
of EINTR. Also let's make code base more uniform by returning negative
values on error.
Fix assert in test-sigbus.c that incorrectly counted positive values as
success. After changing the function return values, that will actually work.

generator: write out special systemd-fsck-usr.service
So far all file systems where checked by instances of
systemd-fsck@.service, with the exception of the root fs which was
covered by systemd-fsck-root.service. The special handling is necessary
to deal with ordering issues: we typically want the root fs to be
checked before all others, and — weirdly — allow mounting it before the
fsck done (for compat with initrd-less boots).
This adds similar special handling for /usr: if the hierarchy is placed
on a separate file system check it with a special
systemd-fsck-usr.service instead of a regular sysemd-fsck@.service
instance. Reason is again ordering: we want to allow mounting of /usr
without the root fs already being around in the initrd, to cover for
cases where the root fs is created on first boot and thus cannot be
mounted/checked before /usr.

network: enable DHCP broadcast flag if required by interface
Some interfaces require that the DHCPOFFER message is sent via broadcast
if they can't receive unicast messages before they've been configured
with an IP address.
E.g., s390 ccwgroup network interfaces operating in layer3 mode face
this limitation. This can prevent the interfaces from receiving an
IP address via DHCP, if the have been configured for layer3.
To allow DHCP over such interfaces, we're introducing a new device
property ID_NET_DHCP_BROADCAST which can be set for those.
The networkd DHCP client will check whether this property is set
for an interface, and if so will set the broadcast flag, unless
the network configuration for the interface has an explicit
RequestBroadcast setting.
Besides that, we're adding a udev rule to set this device property
for ccwgroup devices operating in layer3 mode, which is the case
if the ID_NET_DRIVER property is qeth_l3.
