Allow to setup new bind mounts for a service at runtime (via either
DBUS or a new 'systemctl bind' verb) with a new helper that forks into
the unit's mount namespace.
Add a new integration test to cover this.
Useful for zero-downtime addition to services that are running inside
mount namespaces, especially when using RootImage/RootDirectory.
If a service runs with a read-only root, a tmpfs is added on /run
to ensure we can create the airlock directory for incoming mounts
under /run/host/incoming.
vcs_tag() is slow. When the version-tag meson option is set,
we can use configure_file() directly to speed up incremental
builds.

This adds the support for veritytab.
The veritytab file contains at most five fields, the first four are
mandatory, the last one is optional:
- The first field contains the name of the resulting verity volume; its
block device is set up /dev/mapper/</filename>.
- The second field contains a path to the underlying block data device,
or a specification of a block device via UUID= followed by the UUID.
- The third field contains a path to the underlying block hash device,
or a specification of a block device via UUID= followed by the UUID.
- The fourth field is the roothash in hexadecimal.
- The fifth field, if present, is a comma-delimited list of options.
The following options are recognized only: ignore-corruption,
restart-on-corruption, panic-on-corruption, ignore-zero-blocks,
check-at-most-once and root-hash-signature. The others options will
be implemented later.
Also, this adds support for the new kernel verity command line boolean
option "veritytab" which enables the read for veritytab, and the new
environment variable SYSTEMD_VERITYTAB which sets the path to the file
veritytab to read.
By default, systemd installs various sample configuration files
containing commented-out defaults. Systems seeking to minimize the
number of files in /etc may wish to install directories and
configuration files that have semantic effects, but not install not
commented-out sample configuration files.
Turn install-sysconfdir into a multi-valued option, with a "no-samples"
value to skip installing sample-only configuration files.
This change improves integration with distributions using locale-gen to
generate missing locale on-demand, like Debian-based distributions
(Debian/Ubuntu/PureOS/Tanglu/...) and Arch Linux.
We only ever enable new locales for generation, and never disable them.
Furthermore, we only generate UTF-8 locale.
This feature is only used if explicitly enabled at compile-time, and
will also be inert at runtime if the locale-gen binary is missing.
The next libblkid v2.37 is going to support session offsets for
multi-session CD/DVDs. This feature is implemented by "hint offsets".
These offsets are optional and prober specific (e.g., iso, udf, ...).
For this purpose, the library provides a new function
blkid_probe_set_hint(), and blkid(8) provides a new command-line
option --hint <name>=<offset>. For CD/DVD, the offset name is
"session_offset".
The difference between classic --offset and the new --hint is that
--offset is very restrictive and defines the probing area and the rest
of the device is invisible to the library. The new --hint works
like a suggestion, it provides a hint where the user assumes the
filesystem, but the rest of the device is still readable for the
library (for example, to get some additional superblock information
etc.).
If the --hint is without a value then it defaults to zero.
The option --hint implementation in udev-builtin-blkid.c is backwardly
compatible. If compiled against old libblkid, then the option is used in
the same way as --offset.

Normally ls-files prints the full path to files from the repo root. But when
$GIT_WORK_TREE is set, ls-files prints paths relative to the current
directory. When rebasing, $GIT_WORK_TREE is set in the commands executed from
'rebase -x'. This causes problems if meson config is touched and the meson
reconfigures itself. ($GIT_WORK_TREE shouldn't be relevant, since the paths that
ls-files reports don't depend on the work tree, but whatever.) Let's unset
GIT_WORK_TREE to avoid the issue.

Fixes#18148.
Back in 5248e7e1f1 (July 2017) we moved over to
"_gateway", with the old name declared to be temporary measure. Since we're
doing a bunch of changes to resolved now, it seems to be a good moment to make
this simplification and not add support for the compat name in new code.
This makes commands like 'ninja -C build fuzz-journal-remote' or
'ninja -C build fuzzers' work, even if we have -Dfuzz-tests=false.
Two advantages: correctness of the meson declarations is verified even
if fuzzers are not built, and it easier to do a one-off build to check for
regressions or such.
Follow-up for 1763ef1d49.
Other similar variables use the binary name underscorified and upppercased
(with "_BINARY" appended in some cases to avoid ambiguity). Add "S" to follow
the same pattern for systemd-cgroups-agent.
Based on the discussion in #16715.
A distro (Fedora in particular) may want to enable oomd in a unstable
branch for testing, even though the package as a whole is compiled in release
mode. Let's emit a warning but otherwise allow this.
This is useful for development where overwriting files out side
the configured prefix will affect the host as well as stateless
systems such as NixOS that don't let packages install to /etc but handle
configuration on their own.

There are downsides to using fexecve:
when fexecve is used (for normal executables), /proc/pid/status shows Name: 3,
which means that ps -C foobar doesn't work. pidof works, because it checks
/proc/self/cmdline. /proc/self/exe also shows the correct link, but requires
privileges to read. /proc/self/comm also shows "3".
I think this can be considered a kernel deficiency: when O_CLOEXEC is used, this
"3" is completely meaningless. It could be any number. The kernel should use
argv[0] instead, which at least has *some* meaning.
I think the approach with fexecve/execveat is instersting, so let's provide it
as opt-in.
For scripts, when we call fexecve(), on new kernels glibc calls execveat(),
which fails with ENOENT, and then we fall back to execve() which succeeds:
[pid 63039] execveat(3, "", ["/home/zbyszek/src/systemd/test/test-path-util/script.sh", "--version"], 0x7ffefa3633f0 /* 0 vars */, AT_EMPTY_PATH) = -1 ENOENT (No such file or directory)
[pid 63039] execve("/home/zbyszek/src/systemd/test/test-path-util/script.sh", ["/home/zbyszek/src/systemd/test/test-path-util/script.sh", "--version"], 0x7ffefa3633f0 /* 0 vars */) = 0
But on older kernels glibc (some versions?) implement a fallback which falls
into the same trap with bash $0:
[pid 13534] execve("/proc/self/fd/3", ["/home/test/systemd/test/test-path-util/script.sh", "--version"], 0x7fff84995870 /* 0 vars */) = 0
We don't want that, so let's call execveat() ourselves. Then we can do the
execve() fallback as we want.
We want to compile the new code in CI without having to explicitly specify
-Doomd=true everywhere. Let's enable it by default, and rely on distros
setting -Dmode=release to not have it enabled by default.
Latest glibc has deprecated mallinfo(), so it might become unavailable at some point
in the future. There is malloc_info(), but it returns XML, ffs. I think the information
that we get from mallinfo() is quite useful, so let's use mallinfo() if available, and
not otherwise.
This is just some refactoring: shifting around of code, not change in
codeflow.
This splits up the way too huge systemctl.c in multiple more easily
digestable files. It roughly follows the rule that each family of verbs
gets its own .c/.h file pair, and so do all the compat executable names
we support. Plus three extra files for sysv compat (which existed before
already, but I renamed slightly, to get the systemctl- prefix lik
everything else), a -util file with generic stuff everything uses, and a
-logind file with everything that talks directly to logind instead of
PID1.
systemctl is still a bit too complex for my taste, but I think this way
itc omes in a more digestable bits at least.
No change of behaviour, just reshuffling of some code.
Also, even if login.defs are not present, don't start allocating at 1, but at
SYSTEM_UID_MIN.
Fixes#9769.
The test is adjusted. Actually, it was busted before, because sysusers would
never use SYSTEM_GID_MIN, so if SYSTEM_GID_MIN was different than
SYSTEM_UID_MIN, the tests would fail. On all "normal" systems the two are
equal, so we didn't notice. Since sysusers now always uses the minimum of the
two, we only need to substitute one value.
All this test does is manipulate text files in a subdir specified with --testroot.
It can be a normal unittest without the overhead of creating a machine image.
As a bonus, also test the .standalone version.
We don't (and shouldn't I think) look at them when determining the type of the
user, but they should be used during user/group allocation. (For example, an
admin may specify SYS_UID_MIN==200 to allow statically numbered users that are
shared with other systems in the range 1–199.)
It makes little sense to make the boundary between systemd and user guids
configurable. Nevertheless, a completely fixed compile-time define is not
enough in two scenarios:
- the systemd_uid_max boundary has moved over time. The default used to be
500 for a long time. Systems which are upgraded over time might have users
in the wrong range, but changing existing systems is complicated and
expensive (offline disks, backups, remote systems, read-only media, etc.)
- systems are used in a heterogenous enviornment, where some vendors pick
one value and others another.
So let's make this boundary overridable using /etc/login.defs.
Fixes#3855, #10184.
After https://github.com/systemd/systemd/pull/16981 only the presence of crypt_gensalt_ra
is checked, but there are cases where that function is available but crypt_preferred_method
is not, and they are used in the same ifdef.
Add a check for the latter as well.
Error on meson 0.47:
```
meson.build:885:47: ERROR: Expecting colon got eol_cont.
crypt_header = conf.get('HAVE_CRYPT_H') == 1 ? \
^
```
This seems to have been fixed in meson 0.50 after a report from
https://github.com/mesonbuild/meson/issues/4720
This means that the dbus doc consistency checks will be enabled by default,
including in the CI. I think that will work better than current state where
people do not enable them and them follow-up patches for the docs like the
parent commit must be had.
RC_LOCAL_SCRIPT_PATH_START and RC_LOCAL_SCRIPT_PATH_STOP were was originally
added in the conversion to meson based on the autotools name. In
4450894653 RC_LOCAL_SCRIPT_PATH_STOP was dropped.
We don't need to use such a long name.
Since the loop to check various xcrypt functions is already in place,
adding one more is cheap. And it is nicer to check for the function
directly. People like to backport things, so we might get lucky even
without having libxcrypt.
Let's make libcryptsetup a dlopen() style dep for PID 1 (i.e. for
RootImage= and stuff), systemd-growfs and systemd-repart. (But leave to
be a regulra dep in systemd-cryptsetup, systemd-veritysetup and
systemd-homed since for them the libcryptsetup support is not auxiliary
but pretty much at the core of what they do.)
This should be useful for container images that want systemd in the
payload but don't care for the cryptsetup logic since dm-crypt and stuff
isn't available in containers anyway.
Fixes: #8249
"crypt-util.c" is such a generic name, let's avoid that, in particular
as libc's/libcrypt's crypt() function is so generically named too that
one might thing this is about that. Let's hence be more precise, and
make clear that this is about cryptsetup, and nothing else.
We already had cryptsetup-util.[ch] in src/cryptsetup/ doing keyfile
management. To avoid the needless confusion, let's rename that file to
cryptsetup-keyfile.[ch].
This makes use of the developer mode switch: the test is only done
if the user opted-in into developer mode.
Before the man/update-dbus-docs was using the argument form where
we don't need to run find_command(), but that doesn't work with test(),,
so find_command() is used and we get one more line in the config log.
Similarly to "setup" vs. "set up", "fallback" is a noun, and "fall back"
is the verb. (This is pretty clear when we construct a sentence in the
present continous: "we are falling back" not "we are fallbacking").
Was trying to run src/partition/test-repart.sh on CentOS 8 and the first
resize call kept failing with ERANGE. Turned out that CentOS 8 comes
with libfdisk-devel-2.32.1 which is missing
2f35c1ead6
(in libfdisk 2.33 and up).
Also, let's move the glue for this to src/shared/ so that we later can
reuse this in sysemd-firstboot.
Given that libpwquality is a more a leaf dependency, let's make it
runtime optional, so that downstream distros can downgrade their package
deps from Required to Recommended.
Currently, each change to NEWS triggers a meson reconfigure that
changes SOURCE_EPOCH which causes a full rebuild. Since NEWS changes
relatively often, we have a full rebuild each time we pull from
master even if we pull semi-regularly. This is further compounded
when using branches since NEWS has a relatively high chance to
differ between branches which causes git to update the modification
time, leading to a full rebuild when switching between branches.
We fix this by using the creation time of the latest git tag instead.
Since cryptsetup 2.3.0 a new API to verify dm-verity volumes by a
pkcs7 signature, with the public key in the kernel keyring,
is available. Use it if libcryptsetup supports it.
This way journalctl can make use of libqrencode if it's there, but will
quietly not use it if it isn't.
This means libqrencode remains a build-time dep, but not a strict
runtime dependency.
I figure we should do something similar for a bunch of other "leaf"
libraries we only use few symbols of. Specifically the following are
probably good candidates:
* pcre2
* libpwquality
* p11kit
* elfutils
and possibly:
* libcryptsetup (only in some parts. i.e. building systemd-cryptsetup
without it makes no sense. However building the dissect option with
libcryptsetup as optional dep does make sense)
* possibly the compression libraries (at least the ones we never use for
compression, but only as alternative ones for decompression)
Already covered like this is:
* libxkcommon
Previously we'd used the existance of a specific AF_UNIX socket in the
abstract namespace as lock for disabling lookup recursions. (for
breaking out of the loop: userdb synthesized from nss → nss synthesized
from userdb → userdb synthesized from nss → …)
I did it like that because it promised to work the same both in static
and in dynmically linked environments and is accessible easily from any
programming language.
However, it has a weakness regarding reuse attacks: the socket is
securely hashed (siphash) from the thread ID in combination with the
AT_RANDOM secret. Thus it should not be guessable from an attacker in
advance. That's only true if a thread takes the lock only once and
keeps it forever. However, if a thread takes and releases it multiple
times an attacker might monitor that and quickly take the lock
after the first iteration for follow-up iterations.
It's not a big issue given that userdb (as the primary user for this)
never released the lock and we never made the concept a public
interface, and it was only included in one release so far, but it's
something that deserves fixing. (moreover it's a local DoS only, only
permitting to disable native userdb lookups)
With this rework the libnss_systemd.so.2 module will now export two
additional symbols. These symbols are not used by glibc, but can be used
by arbitrary programs: one can be used to disable nss-systemd, the other
to check if it is currently disabled.
The lock is per-thread. It's slightly less pretty, since it requires
people to manually link against C code via dlopen()/dlsym(), but it
should work safely without the aforementioned weakness.
Use -Dstandalone-binaries=yes to enable building and installing this standalone
version of the binary without a dependency on the systemd-shared solib.
Also move the list of sources for systemd-tmpfiles to its own meson.build file.
This adds an option to build standalone binaries that do not depend on the
systemd-shared library. This option can be handy to build binaries that can be
useful on a non-systemd system, binaries such as systemd-sysusers and
systemd-tmpfiles have been previously requested, but installing them with all
the required dependencies pulls in too much code that isn't really relevant for
those use cases. The standalone use case is also relevant in containers, where
minimizing the size of the container image is quite relevant.
For now, only `systemd-sysusers` is also built as a standalone binary.
The standalone binaries are installed as `/usr/bin/%{name}.standalone`, the
packaging system is reponsible for renaming those into the correct names
during the packaging step. RPM is able to do so with RemovePathPostfixes:
The default behavior is to build shared binaries only, since this option is
mainly intended for building distribution packages.
Tested that a proper separate binary is built when using this option and
that having it disabled (or using the default Meson configuration) does not
produce a binary for this option.
Let systemd load a set of pre-compiled AppArmor profile files from a policy
cache at /etc/apparmor/earlypolicy. Maintenance of that policy cache must be
done outside of systemd.
After successfully loading the profiles systemd will attempt to change to a
profile named systemd.
If systemd is already confined in a profile, it will not load any profile files
and will not attempt to change it's profile.
If anything goes wrong, systemd will only log failures. It will not fail to
start.
Since the separate binaries contain mostly the same code,
this almost halves the size of the installation.

398K /bin/udevadm
391K /lib/systemd/systemd-udevd
after:
431K /bin/udevadm

This generator can be used by desktop environments to launch autostart
applications and services. The feature is an opt-in, triggered by
xdg-desktop-autostart.target being activated.
Also included is the new binary xdg-autostart-condition. This binary is
used as an ExecCondition to test the OnlyShowIn and NotShowIn XDG
desktop file keys. These need to be evaluated against the
XDG_CURRENT_DESKTOP environment variable which may not be known at
generation time.

The slow-tests= option already enables fuzzers as well, however, this
option can't be used in the "fully sanitized" runs, as certain slow
tests are affected by the performance quite significantly.
This option allows us to enable only fuzzers without the slow tests to
meet the needs of such runs.
Debian Policy encourages to preserve timestamps whenever possible in the
tarballs, thus stable release updates of systemd usually do not bump NEWS file
timestamp. And thus time-epoch remains the same for the lifetime of a release.
It would be better, if each new stable release rebuild of systemd would bump
the time epoch a bit. But at the same time remain
reproducible. SOURCE_DATE_EPOCH is an environmnet variable defined for this
purpose. Thus if available, prefer that, instead of the NEWS file modification
time.
For example, on Debian/Ubuntu under the reproducible builds the
SOURCE_DATE_EPOCH is set to the timestamp from the packaging metadata, thus it
is incremented on every new stable release update, whilst preserving
reproducible builds capability.

The kernel should not define the length of the array, but it does. We can't fix
that, so let's use a cast to avoid the warning.
For https://github.com/systemd/systemd/issues/6119#issuecomment-626073743.
v2:
- use #pragma instead of a cast. It seems the cast only works in some cases, and
gcc is "smart" enough to see beyond the cast. Unfortunately clang does not support
this warning, so we need to do a config check whether to try to suppress.
Ideally, assert_cc() would be used for this, so that it is not possible to even
compile systemd with something like '-Dfallback-hostname=.foo'. But to do a
proper check we need to call hostname_is_valid(), and we cannot depend on being
able to run code (e.g. during cross-compilation). So let's do a very superficial
check in meson, and a proper on in test-util.
There are two libc APIs for accessing the user database: NSS/getpwuid(),
and fgetpwent(). if we run in --root= mode (i.e. "offline" mode), let's
use the latter. Otherwise the former. This means tmpfiles can use the
database included in the root environment for chowning, which is a lot
more appropriate.
Fixes: #14806
In a few cases, the prefix was originally necessary because a different helper
script was used for automake, and a different one for meson. But now we use
meson exclusively, and the prefix isn't useful. This also synchronizes the
target name, file name, and variable name in meson.build. The targets exposed
by meson didn't have the prefix, so the user interface is unchanged.
(The prefix is retained in the few tools that are used for meson itself,
e.g. meosn-vcs-tag.sh, meson-make-symlink.sh, etc.)

Given that judging by https://github.com/systemd/systemd/issues/13039 it doesn't seem to be
the first time issues like that have been missed I think it would be better to turn nonnull on
and get around false positives on a case-by-case basis with DISABLE_WARNING_NONNULL .. REENABLE_WARNING
Reopens https://github.com/systemd/systemd/issues/6119
By using a newline after executable( and run_target(, we get less
indentation and the indentation level does not change when the returned
object is saved to a variable.
Enables building systemd without systemd-analyze, which in
return saves approx. 4 MB of space upon installing systemd.

On azure systemd.systemd ci, the build would fail with:
meson.build:53:0: ERROR: Program or command '/home/appuser/fuzzer/tools/add-git-hook.sh' not found or not executable
We use find_program() for all helpers, so let's do it for this one too.
This should solve the issue, whatever it exactly is.
Build option "link-timesyncd-shared" to build a statically linked
systemd-timesyncd by using
-Dlink-udev-shared=false -Dlink-timesyncd-shared=false
on systems with full systemd stack except systemd-timesyncd, such
as RHEL/CentOS 8.
Fixes systemd build in Fedora rawhide.
The old ldsdir option is not useful, because both the directory and the
file name changed. Let's remove the option and try to autodetect the file
name. If this turns out to be not enough, a new option to simply specify
the full path to the file can be added.
