These are built from the same sources as the regular binaries, so we
end up with the same sources multiple times in the compilation database
but with different command line arguments, which trips up tooling that
uses the compilation database. Let's not define the standalone targets if
the option is not enabled to avoid this problem.
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.
The old description makes users wrongly assume that the cap of 4G
applied, even when the user specifies a value that will result in higher
than 4G. This commit avoids this misunderstanding.
conf-parser.h pulls in a lot of other headers as needed by all the
macros it defines. We can't easily move the implementations of these
macro to conf-parser.c, so let's instead introduce conf-parser-forward.h
with just the stuff in it needed by other header files.
We'll make use of this when cleaning up includes to only include the
minimal parts of conf-parser.h that are required by other headers without
pulling in the kitchen sink.
To make sure everything still compiles, we add a preliminary include
of forward.h to tests.h to make sure it is included in every test source
file. We'll clean up the tests.h includes in a later commit.
We also add a <errno.h> include to errno-list.h to keep test-errno-list.c
compiling. It'll be removed again when we clean up includes in src/basic.
Split out of #37344.
constants.h defines a bunch of constants that use macros from
time-util.h, so add the needed include. To avoid cyclic dependencies,
we move the HAS_FEATURE_MEMORY_SANITIZER and HAS_FEATURE_ADDRESS_SANITIZER
logic to macro.h and get rid of the constants.h include there.
The rest of this commit is adding missing constants.h includes where
needed due to it being removed from macro.h.
Various long standing issues (at least: #5573#14159#20485#21260#24532#32022#18056) have been asking for a way to delegate DNS
resolution of specific domains to very specific DNS servers.
This PR goes a major step towards that goal by adding a new concept "DNS
Delegate" which allows to configure just that. Basically, this adds a
third kind of DNS scope to resolved's logic: besides the per-link and
global DNS scopes there are now also "delegate" scopes, which can be
created by dropping in a new file /etc/systemd/dns-delegate/*.conf. They
carry DNS= and Domains= lines just like the global setting or what the
per-link configuration can carry.
And they are consulted the same way as link DNS scopes are considered,
following the same routing rules.
This allows to configure these DNS delegates statically via drop-in
files as mentioned, and only adds the most basic functionality. Later on
we might want to extend this:
1. Allow dynamic creation of DNS delegates via IPC with lifecycle bound
to IPC client (usecase: installing a DNS delegate that routes traffic to
some DNS-over-TLS server once basic setup is complete).
2. Allow configuration of protocol details per delegate the same way
this is currently allowed per-link.
3. Instead of strictly using DNS as delegation protocol, support an
alternative varlink based protocol (without retransmission problems and
so on) that systemd-machined and similar can implement.
This PR is not complete yet. Lacks docs and tests. Seems to work fine in
my local tests however.

Let's handle the per-link and the global dns server/search domain
property parsing the same. Let's use a flags field for three separate
booleans, and unify more code.
This permits configuration of additional "delegates" which ensure that
lookups for certain DNS zones are routed to specific sets of DNS
servers, in addition to the routes we create for each network interface.
For now, this allows only static configuration, but eventually we should
open this up to IPC.

(Fixes#32022, because now redundant)
This new enum field is supposed to indicate why a DnsScope came to be.
For now it distinguishes two origins: the "global" one (which is what is
configured in resolved.conf) and "link" ones (which are synthesized for
each link).
The field as is is pretty redundant, the same information can be
determined from whether the .link field is set or not.
This is pretty much just preparation for later commits that add
statically configured additional DnsScopes whose origin shall be encoded
with this.
Continuation of 7851732262 and
5a65d2e535. Absolute paths are always
nicer for the user because it's much easier to figure out where the
file is located. And printing some paths with the prefix and some
without was quite confusing.
Kernels are loaded from two partitions (XBOOTLDR and ESP). In the past this
wasn't always so, but a while ago the docs and the code were updated to load
from both locations. The $BOOT location specifies where to install only. So
rework the status output to print both locations and indicate which one is
$BOOT by appending ", $BOOT".
Also change the section title to "… Locations". We don't show *entries* here,
so the old title could be a bit confusing.
Example:
Boot Loader Entry Locations:
ESP: /efi (/dev/disk/by-partuuid/31659406-5a17-46ec-8195-0dea1667db58)
XBOOTLDR: /boot (/dev/disk/by-partuuid/4f8a8fe9-4b45-4070-9e9b-a681be51c902, $BOOT)
token: fedora
NetworkManager imports some systemd code, which we then build with
`-Wcast-align=strict`. This results in this warning:
```
../src/libnm-systemd-shared/src/basic/pidfd-util.c: In function 'pidfd_get_inode_id':
../src/libnm-systemd-shared/src/basic/pidfd-util.c:255:41: warning: cast increases required alignment of target type [-Wcast-align]
255 | *ret = *(uint64_t*) fh.file_handle.f_handle;
| ^
```
Since the address of `f_handle` should always be aligned at the word
boundary (it is preceded by 2 int`s` in `file_handle`), this patch uses
`CAST_ALIGN_PTR()` to avoid this warning.
