95e104e049 sd-radv: make prefix/route prefix lifetime can be specified with independently with valid_until
Previously, valid_until (or preferred_until for preferred lifetime) was
calculated from lifetime. So, when an upstream interface acquire a
dynamic prefix (e.g. through DHCPv6-PD) with long lifetime, then sd-radv
advertise the same lifetime. It may not be desired for some situations.

6663b509d8 bootctl: refuse parsing unknown special '@' entry ids
Let's make sure '@' is never written as entry ID into any EFI variable,
as we want the ability to add new ids like this later on, with them
resulting in a clear error on older implementations.

change indicator used for later versions of VirtualBox (#21127)
Detection of VirtualBox is accomplished in the existing code by *either* `innotek GmbH`
or `Oracle Corporation` existing in any of:

- /sys/class/dmi/id/product_name
- /sys/class/dmi/id/sys_vendor
- /sys/class/dmi/id/board_vendor
- /sys/class/dmi/id/bios_vendor

With Oracle's physical servers, both `/sys/class/dmi/id/sys_vendor` and
`/sys/class/dmi/id/board_vendor` contain `Oracle Corporation`, so those
servers are detected as `oracle` (VirtualBox).

VirtualBox has the following values in the latest versions:

- /sys/class/dmi/id/product_name: `VirtualBox`
- /sys/class/dmi/id/sys_vendor: `innotek GmbH`
- /sys/class/dmi/id/board_vendor: `Oracle Corporation`
- /sys/class/dmi/id/bios_vendor: `innotek GmbH`

Presumably the existing check for `innotek GmbH` is meant to detect
older versions of VirtualBox, while changing the second checked value
from `Oracle Corporation` to `VirtualBox` will reliably detect later and future
versions.

8f1daefce6 json: do something remotely reasonable when we see NaN/infinity
JSON doesn't have NaN/infinity/-infinity concepts in the spec.
Implementations vary what they do with it. JSON5 + Python simply
generate special words "NAN" and "Inifinity" from it. Others generate
"null" for it.

At this point we never actually want to output this, so let's be
conservative and generate RFC compliant JSON, i.e. convert to null.

One day should JSON5 actually become a thing we can revisit this, but in
that case we should implement things via a flag, and only optinally
process nan/infinity/-infinity.

This patch is extremely simple: whenever accepting a
nan/infinity/-infinity from outside it converts it to NULL. I.e. we
convert on input, not output.

the behavior.

079f94edfa network: dhcp6: do not reconfigure/restart DHCPv6 clients when a new downstream appears
Previously, when a downstream appears which requests delegated prefix to
be assigned, then possibly restart all DHCPv6 clients for another
interfaces.

This makes networkd always honor the UseDelegatedPrefix= setting, and
not restart DHCPv6 clients.

0f5ef9b62a network: dhcp6: introduce UseDelegatedPrefix= setting and enable by default
Previously, the prefix delegation is enabled when at least one
downstream interfaces request it. But, when the DHCPv6 client on the
upstream interface is configured, some downstream interfaces may not
exist yet, nor have .network file assigned.

Also, if a system has thousands of interfaces, then the previous logic
introduce O(n^2) search.

This makes the prefix delegation is always enabled, except when it is
explicitly disabled. Hopefully, that should not break anything, as the
DHCPv6 server should ignore the prefix delegation request if the server
do not have any prefix to delegate.

b4564f4e8f network: delay dropping addresses or so on reloading .network files
When a .network file is updated but its change is not so big, it is not
necessary to first drop all configs and then reassign later again.
This slightly optimize such situation. First foreignize all configs, and
then drop later when it is not requested by the updated .network file.
