1d84a3c779 network/dhcp4: accept local subnet routes from DHCP
RFC3442 specifies option 121 (Classless Static Routes) that allow a DHCP
server to push arbitrary routes to a client. It has a Local Subnet
Routes section expliciting the behavior of routes with a null (0.0.0.0)
gateway.

Such routes are to be installed on the interface with a Link scope, to
mark them as directly available on the link without any gateway.

Networkd currently drops those routes, which is against the RFC, as
Linux has proper support for such routes.

Fixes: 7f20627 ("network: dhcp4: ignore gateway in static routes if destination is link-local or in the same network")

9c45bfb2ac ukify: don't install ukify man page if ukify is not enabled
Checking for gnu-efi is not enough, since ukify can be explicitly
disabled.

907046282c bpf: fix restrict_fs on s390x
Linux kernel's bpf-next contains BPF LSM support for s390x. systemd's
test-bpf-lsm currently fails with this kernel.

This is an endianness issue: in the restrict_fs bpf program,
magic_number has type unsigned long (64 bits on s390x), but magic_map
keys are uint32_t (32 bits). Accessing magic_map using 64-bit keys may
work by accident on little-endian systems, but fails hard on big-endian
ones.

Fix by casting magic_number to uint32_t.

181eea677d importd: Always specify file unpacked by tar
Despite popular belief, the default file extracted by GNU tar is not stdin.  It
is the value of the TAPE environment variable, falling back on a compile-time
constant.  On my system, the default value is /dev/full, which causes tar to
just spin forever due to --ignore-zeros.  Always specifying this flag is the
safe thing to do.

  ~$ tar --show-defaults
  --format=gnu -f/dev/full -b20 --quoting-style=escape
  --rmt-command=/usr/sbin/grmt

60f42f7ec2 test-systemd-tmpfiles: Fix execution when user is not in /etc/passwd
We might be running in a chroot as a uid that doesn't exist in /etc/passwd.
Let's make sure we don't fail in this scenario.

We pass $HOME when resetting the env so that we can find a home directory
and skip tests that depend on user name/group.

a7795a4ecf sleep: introduce siphash24_compress_id128()
Also, rename get_battery_identifier() to siphash24_compress_device_sysattr().

This also makes any errors in sd_id128_get_machine() or id128_get_product()
ignored. For the machine ID, the failure should not be significant unless
the file stored in the discharge level is reused by another system, which
is quite unusual. For the product ID, if the firmware provides useless
ID (all zero or all 0xFF), then loading/storing the discharge rate
becomes completely broken, that should be avoided.

Note, now sysattrs are used instead of properties in uevent files, but
both provide the same information, hence no functionality should be
changed.

4f58b656d9 sleep: introduce SuspendEstimationSec=
Before v252, HibernateDelaySec= specifies the maximum timespan that the
system in suspend state, and the system hibernate after the timespan.

However, after 96d662fa4c, the setting is
repurposed as the default interval to measure battery charge level and
estimate the battery discharging late. And if the system has enough
battery capacity, then the system will stay in suspend state and not
hibernate even if the time passed. See issue #25269.

To keep the backward compatibility, let's introduce another setting
SuspendEstimationSec= for controlling the interval to measure
battery charge level, and make HibernateDelaySec= work as of v251.

This also drops implementation details from the man page.

Fixes #25269.

b6033b7060 tmpfiles: automatically create /etc/credstore/ and friends
This adds a tmpfiles.d/ snippet for LoadCredential= style credentials
directories in /etc/ and /run/.

This is done primarily to ensure that the access modes for the dirs are
set up properly, in the most restrictive ways. Specifically these are
set to 0000, so that CAP_DAC_OVERRIDE is necessary to enumerate and read
the credentials, and being UID=0 is not sufficient to do so.

This creates /etc/credstore/, but leaves /run/credstore/ absent if
missing, for now. Thinking is: the latter being non-persistent is
created by software usually, not manually by users, and hence more
likely right. But dunno, we might want to revisit this sooner or later.

This is ultimately an exercise to advertise the LoadCredential= concept
a bit, and do so in a reasonably secure way, underlining the safety of
the concept.
