Lennart Poettering 90810f7a37 sd-dhcp-server: some function prototype fix-ups
Let's use size_t for numbers of entries in memory.

Let's use const wherever appropriate.

Drop `_server` suffix from function name where we don't have it for
similar other cases.

Lennart Poettering fb29cdbef2 tree-wide: make sure our control buffers are properly aligned
We always need to make them unions with a "struct cmsghdr" in them, so
that things properly aligned. Otherwise we might end up at an unaligned
address and the counting goes all wrong, possibly making the kernel
refuse our buffers.

Also, let's make sure we initialize the control buffers to zero when
sending, but leave them uninitialized when reading.

Both the alignment and the initialization thing is mentioned in the
cmsg(3) man page.

Lennart Poettering a258f4915a tree-wide: use CMSG_SPACE() (and not CMSG_LEN()) to allocate control buffers
We need to use the CMSG_SPACE() macro to size the control buffers, not
CMSG_LEN(). The former is rounded up to next alignment boundary, the
latter is not. The former should be used for allocations, the latter for
encoding how much of it is actually initialized. See cmsg(3) man page
for details about this.

Given how confusing this is, I guess we don't have to be too ashamed
here, in most cases we actually did get this right.

Zbigniew Jędrzejewski-Szmek 38b38500c6 tree-wide: use "hostname" spelling everywhere
It's not that I think that "hostname" is vastly superior to "host name". Quite
the opposite — the difference is small, and in some context the two-word version
does fit better. But in the tree, there are ~200 occurrences of the first, and
>1600 of the other, and consistent spelling is more important than any particular
spelling choice.

David Wood 7354900ddd network: Fix split in SendOption= on client and server
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.

This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.

The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.

Zbigniew Jędrzejewski-Szmek 8ff4585ffa sd-dhcp-client: merge client_send_release() into sd_dhcp_client_send_release()
The public function and the implementation were split into two for
no particular reason.

We would assert() on the internal state of the client. This should not be done
in a function that is directly called from a public function. (I.e., we should
not crash if the public function is called at the wrong time.)
assert() is changed to assert_return().

And before anyone asks: I put the assert_returns() *above* the internal
variables on purpose. This makes it easier to see that the assert_returns()
are about the state that is passed in, and if they are not satisfied, the
function returns immediately. The compiler doesn't care either way, so
the ordering that is clearest to the reader should be chosen.

Siddharth Chandrasekara afe42aef39 dhcp4: make IPServiceType configurable
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.

Georg Müller ef90b6a4fb sd-radv: if lifetime < SD_RADV_DEFAULT_MAX_TIMEOUT_USEC, adjust timeout (#13491)
The RFC states that lifetime (AdvDefaultLifetime) must be at least
MaxRtrAdvInterval (which more or less corresponds to SD_RADV_DEFAULT_MAX_TIMEOUT_USEC
in systemd).

To fulfill this limit, virtually lower MaxRtrAdvInterval and MinRtrAdvInterval
accordingly.

Also check that min is not lower than 3s and max is not lower than 4s.

Zbigniew Jędrzejewski-Szmek adfafd88b2 Revert "shared/conf-parser,networkd: EXTRACT_UNQUOTE|EXTRACT_RETAIN_ESCAPE → EXTRACT_UNQUOTE"
This reverts commit 8a07b4033e.
The tests are kept. test-networkd-conf is adjusted to pass.

This fixes #13276. I think current rules are extremely confusing, as the
case in test-networkd-conf shows. We apply some kinds of unescaping (relating
to quoting), but not others (related to escaping of special characters).
But fixing this is hard, because people have adjusted quoting to match
our rules, and if we make the rules "better", things might break in unexpected
places.

Zbigniew Jędrzejewski-Szmek bc67342e94 libsystemd-network: make option_append() atomic and make the code a bit clearer
Comparisons are done in the normal order (if (need > available), not if (available < need)),
variables have reduced scope and are renamed for clarity.

The only functional change is that if we return -ENAMETOOLONG, we do that
without modifying the options[] array.

I also added an explanatory comment. The use of one offset to point into three
buffers is not obvious.

Coverity (in CID#1402354) says that sname might be accessed at bad offset, but
I cannot see this happening. We check for available space before writing anything.

Zbigniew Jędrzejewski-Szmek 8a07b4033e shared/conf-parser,networkd: EXTRACT_UNQUOTE|EXTRACT_RETAIN_ESCAPE → EXTRACT_UNQUOTE
It's hard to even say what exactly this combination means. Escaping is
necessary when quoting to have quotes within the string. So the escaping of
quote characters is inherently tied to quoting. When unquoting, it seems
natural to remove escaping which was done for the quoting purposes. But with
both flags we would be expected to re-add this escaping after unqouting? Or
maybe keep the escaping which is not necessary for quoting but otherwise
present? This all seems too complicated, let's just forbid such usage and
always fully unescape when unquoting.
