We can jump to chase_one from two places. In the first 'todo' is set to
'buffer', which comes from path_make_absolute_cwd() and is nonnull In the
second 'todo' is set to 'joined' which is checked to be nonull a few lines
above the jump. So let's kill the code that deals with null todo there.
meson: recompile all sources for install_libudev_static and install_libsystemd_static
This means that when those targets are built, all the sources are built again,
instead of reusing the work done to create libbasic.a and other convenience static
libraries. It would be nice to not do this, but there seems to be no support in
our toolchain for joining multiple static libraries into one. When linking
a static library, any -l arguments are simply ignored by ar/gcc-ar, and .a
libraries given as positional arguments are copied verbatim into the archive
so they objects in them cannot be accessed.
https://stackoverflow.com/questions/2157629/linking-static-libraries-to-other-static-libraries
suggests either unzipping all the archives and putting them back togather,
or using a linker script. Unzipping and zipping back together seems ugly.
The other option is not very nice. The linker script language does not
allow "+" to appear in the filenames, and filenames that meson generates
use that, so files would have to be renamed before a linker script was used.
And we would have to generate the linker script on the fly. Either way, this
doesn't seem attractive. Since those static libraries are a niche use case,
it seems reasonable to just go with the easiest and safest solution and
recompile all the source files. Thanks to ccache, this is probably almost as
cheap as actually reusing the convenience .a libraries.
test-libsystemd-sym.c and test-libudev-sym.c compile fine with the generated
static libs, so it seems that they indeed provide all the symbols they should.
UserClass=
A DHCPv4 client can use UserClass option to identify the type or category of user or applications
it represents. The information contained in this option is an string that represents the user class
of which the client is a member. Each class sets an identifying string of information to be used by the DHCP service to classify clients. Takes a whitespace-separated list.
namespace: extend list of masked files by ProtectKernelTunables=
This adds a number of entries nspawn already applies to regular service
namespacing too. Most importantly let's mask /proc/kcore and
/proc/kallsyms too.
nspawn: move nspawn cgroup hierarchy one level down unconditionally
We need to do this in all cases, including on cgroupsv1 in order to
ensure the host systemd and any systemd in the payload won't fight for
the cgroup attributes of the top-level cgroup of the payload.
This is because systemd for Delegate=yes units will only delegate the
right to create children as well as their attributes. However, nspawn
expects that the cgroup delegated covers both the right to create
children and the attributes of the cgroup itself. Hence, to clear this
up, let's unconditionally insert a intermediary cgroup, on cgroupsv1 as
well as cgroupsv2, unconditionally.
This is also nice as it reduces the differences in the various setups
and exposes very close behaviour everywhere.
Let's not make /run too special and let's make sure the source file is
not guessable: let's use our regular temporary file helper calls to
create the source node.
nspawn: lock down a few things in /proc by default
This tightens security on /proc: a couple of files exposed there are now
made inaccessible. These files might potentially leak kernel internals
or expose non-virtualized concepts, hence lock them down by default.
Moreover, a couple of dirs in /proc that expose stuff also exposed in
/sys are now marked read-only, similar to how we handle /sys.
The list is taken from what docker/runc based container managers
generally apply, but slightly extended.
mount-setup: add a comment that the character/block device nodes are "optional" (#8893)
if we lack privs to create device nodes that's fine, and creating
/run/systemd/inaccessible/chr or /run/systemd/inaccessible/blk won't
work then. Document this in longer comments.
test: don't send image building output to /dev/null (#8886)
Yes, the output is sometimes annyoing, but /dev/null is not the right
place...
I figure this redirection was left in from some debugging session, let's
fix it, and make the setup_basic_environment invocation like in all
other test scripts.
timesync: try to reload DBus configuration when RequestName() fails
If dbus.service starts earlier than the dynamic user systemd-timesync
is realized, then the dbus policy file for timesyncd does not loaded
and timesyncd fails to request name.
To support such case, try to reload dbus configuration when requesting
name fails.

util: make signal_from_string() accept RTMIN, RTMAX, and RTMAX-n
Before this, `signal_from_string()` accepts simple signal name
or RTMIN+n. This makes the function also accept RTMIN, RTMAX,
and RTMAX-n.
Note that RTMIN+0 is equivalent to RTMIN, and RTMAX-0 is to RTMAX.
This also fixes the integer overflow reported by oss-fuzz #8064.

Nested KVM is very flaky as we learnt from our CI. Hence, let's avoid
KVM whenever we detect we are already running inside of KVM.
Maybe one day nested KVM is fixed, at which point we can turn this on
again, but for now let's simply avoid nested KVM, since reliable CI is
more important than quick CI, I guess.
And yes, avoiding KVM for our qemu runs does make things substantially
slower, but I think it's not a complete loss.
man: suffix all dir paths in file-hierarchy(7) with "/"
Our CODING_STYLE document suggests to suffix all paths referring to dirs
rather than regular files with a "/" in our docs and log messages.
Update file-hierarchy(7) to do just that.
