This renames and splits link_may_have_ipv6ll() into
link_ipv6ll_enabled_harder() and link_multicast_enabled(),
as they are completely irrelevant to each other.
Also, this makes link_ipv6ll_enabled_harder() work non-Wireguard
interfaces.
We use symbols provided by unistd.h without including it. E.g.
open(), close(), read(), write(), access(), symlink(), unlink(), rmdir(),
fsync(), syncfs(), lseek(), ftruncate(), fchown(), dup2(), pipe2(),
getuid(), getgid(), gettid(), getppid(), pipe2(), execv(), _exit(),
environ, STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO, F_OK, and their
friends and variants, so on.
Currently, unistd.h is indirectly included mainly in the following two paths:
- through missing_syscall.h, which is planned to covert to .c file.
- through signal.h -> bits/sigstksz.h, which is new since glibc-2.34.
Note, signal.h is included by sd-eevent.h. So, many source files
indirectly include unistd.h if newer glibc is used.
Currently, our baseline on glibc is 2.31. We need to support glibc older
than 2.34, but unfortunately, we do not have any CI environments with
such old glibc. CIFuzz uses glibc-2.31, but it builds only fuzzers, and
many files are even not compiled.

We specify >= 0.62 as the supported version, so drop the duplicate name in all cases
where it is the same as outputs[0], i.e. almost all cases.

This also makes ip6tnl can be created without specifying Mode= setting,
as the kernel accepts new-link netlink message without the
IFLA_IPTUN_PROTO attribute.
No effective functional change, just refactoring and preparation for
later change.
With 9ccc369ff3, PersistLeases= is
disabled on the host side virtual interfaces for containers.
However, even it is not necessary to save the leases for containers
on a persistent storage, still we should save them on somewhere.
Otherwise, leases will be lost when networkd on the host is restarted
or the host side interface is reconfigured.
This introduce PersistLeases=runtime to save and load leases on runtime
storage.
Add the following network option to enable BOOTP:
[DHCPv4]
Bootp=yes
This will allow a two message request / reply sequence that doesn't
require DHCP message types.

Previously, the property was checked only when an uevent is received,
so even if an interface has ID_NET_MANAGED_BY property, the interface
will be configured by networkd when reconfiguration is triggered e.g.
when interface state is changed.
Follow-up for ba87a61d05.
Fixes#36997.
While the `port_vlan_id` field was already present in the
`sd_lldp_neighbor`, it wasn't currently parsed from the LLDP packet.
Added support for that as well as a small parsing test.
Closes#28354.
In function `tc_init`, hz is parsed from the content of file
`"/proc/net/psched"` and can be 0.
In function `hierarchy_token_bucket_class_verify`, hz is directly used
as a divisor in
`htb->buffer = htb->rate / hz + htb->mtu;` without any check. This adds a check on hz before using it as a divisor.

If master ifindex is non-zero, then the carrier state and operational
state of the interface may be the enslaved state.
As the operational state is saved in link state file, and read by
wait-online, we need to update the state file when the master ifindex is
changed.
When an interface leaved from the master interface, then reading
IFLA_MASTER attribute causes ENODATA. When the interface was previously
enslaved to another interface, we need to remove reference to the
interface from the previous master interface.
This is especially important when
```
ip link set dev eth0 nomaster
```
is called.
Fixes a bug introduced by 0d411b7f8f (v249).
Fixes#37629.
clang-include-cleaner has a hard time figuring out unused includes
with all the macro string concatentation we're doing in test_table().
Let's help it out a little by also passing the enum type into test_table().
While technically not needed, this makes the tests a bit more self-descriptive
and not really much more verbose so it feels like a good chance regardless,
even if the primary purpose is to help clang-include-cleaner figure out
used and unused includes.
Let's ensure all of our source file names are unique without having
to take the directory into account.
This allows us to create meson targets or unit tests identified by the
the name of the source file they operate on without having to include
the full path of the source file in the target or test name to avoid
conflicts.
