This performs the same semantic transformation as the Coccinelle
script 'strdupa.cocci'.
Somehow the existing semantic patch is not properly triggering on
this 'string_replace_char' test.
Then, try to drop multiple protocol specifiers at the end.
Strictly speaking, this breaks backward compatibility:
if eth0 and eth0.42 exists, then previously,
echo 'nameserver 192.168.0.1' | resolvconf -a eth0.42
adds the DNS server to eth0 instead of eth0.42, as we unconditionally
dropped the specifier after the last dot, and
echo 'nameserver 192.168.0.1' | resolvconf -a eth0.42.dhcp
adds the DNS server to eth0.42. However, with this commit, now
the both commands add the DNS server to eth0.42. But, hopefully,
this should be preferable behavior.
Fixes#25032.
We treat symlinks to unit files outside of the search path differently from
symlinks to unit files *in* the search path. The former are "linked" unit
files, while the latter are enablement symlinks and such and will be removed
when disabling the unit.
The history of the check for in_search_path() is interesting: this condition
was added already in the first version of the code in
830964834f. Since the beginning, matching
arguments would simply be ignored. I think this is dubious. The man page says:
> Link a unit file that is *not* in the unit file search paths
> into the unit file search path
But for backwards-compat, let's continue to silently do nothing for files
*in* the search path.
The case of symlinks to unit files underneath the search path, but in some
subdirectory, is less clear. We didn't check for this case, so it was
implicitly allowed. But that's just an oversight, we don't want to allow people
to create additional subhierarchies under our hierarchy. Let's check for this
case and refuse.
Closes#24605.
This adds a check for an allocation error for the calls to install_changes_add()
where we're plannig to return success from the call. In cases where we're
returning failure, it doesn't matter as much: the operation will fail anyway,
and if the allocation fails, we'll just get a less descriptive error message.
The machinery to report a good error message only works if the
error was registered with install_changes_add() and a file name. Otherwise
we only get a generic "Op failed: %m" message.
In some places -EINVAL is replaced by -EUCLEAN, so that we get the proper
error message.
The function was written to only return an error from internal allocation
failures, because when using it to create a bus message, we want to distinguish
a failed operation from an allocation error when sending the reply. But it
turns out that the only caller that makes this distinction checks that the
passed-in errno value ('type') is not negative beforehand. So we can make the
function pass 'type' value through, which makes most of the callers nicer.
No functional change.
Semi-quoting https://github.com/systemd/systemd/issues/25057:
clang-16 has made the choice to turn on -Werror=implicit-function-declaration,implicit-int.
(See Gentoo's tracker bug https://bugs.gentoo.org/870412).
Added in commit 132c73b57a, systemd now does a
check to see if libatomic is needed with some compile/link tests with e.g.
__atomic_exchange_1, but the tests don't provide a prototype for
__atomic_exchange_1 so with clang-16 the test fails, breaking the build.
Let's simplify things by linking to libatomic unconditionally if it is found
and seems to work. If actually unneeded, it might be dropped via --as-needed.
This seems to work with gcc and clang.
declare_dependency() is used instead of cc.find_library(), because the latter
picks up a symlink in gcc private directory (e.g.
/usr/lib/gcc/x86_64-redhat-linux/12/libatomic.so), and we don't want that.
Fixes#25057.
Also, unify the string quotation a bit and drop one unnecessary
expression syntax (as everything in `if` statements is automatically
evaluated as an expression).
This fix unfortunately introduced a much worse regression that
is affecting many users, so let's revert it for now and rework
it in the next release.
This reverts commit 5ded3917a1.

The precise bounds of the scheduling priority depend on the scheduling policy,
so depending on the order in which the two settings are specified the
validation might pass or fail.
When checking the setting only validate the outer range (valid values in general are 0 to 99),
and let the execution fail later if the priority does not match the
specified policy (1 to 99 for RR/FIFO, 0 for the rest).
Fixes https://github.com/systemd/systemd/issues/20320
Allow-listing a device implicitly blocks everything else, so this
has the opposite of the intended effect when PrivateDevices= is
not used.
Allow-list char-rtc only if there is a device policy set.

The test would fail when addresses were being removed in parallel. In general,
the check is only valid when the machine configuration is static, which in
general isn't true.

The logs show that there's a huge number of private addresses, probably from
some other test running in parallel.
This fixes a few unrelated issues:
- when ENABLE_MACHINED is false, machinectl is not installed, but _sd_machines
is still used in a few places that want to complete -M and such.
Also, bash completion calls machinectl in various places.
Make missing machinectl mean "no machines" in this case, so
that no error is generated in the callers.
- machinectl list --full would print multiple lines of output per machine,
breaking grep, issue introduced in e2268fa437.
Using --max-addresses=1 would fix the issue, but let's use
--max-addresses=0 because we now can.
- the lists used in various places were slightly different for no good reason.
- don't use a subshell if not necessary.
The code for bash still uses the same combined list of images and running
machines for various commands. The zsh code uses images for start/clone, and
running machines for the rest. Maybe something to fix in the future.
Replaces #25048.
