Otherwise, some tests may disturb others, e.g.,
NetworkdNetWorkTests.test_routing_policy_rule_port_range and
NetworkdNetWorkTests.test_routing_policy_rule.
Not sure how I missed this, but we of course need to wait for the
"systemd-run" commands to finish before we can check the output files
this generated.
It tests importing and exporting, and a few other machinectl commands.
It currently does not test pulling (i.e. http downloads), but we might
want to add that later on.
For netdev, config files are loaded twice, and the first time,
only Match and NetDev setions are read. So, the test given by
the previous commit covers only the second loading.
This adds another test that also covers the first loading.
systemd only uses functions that are as of Linux 4.15+ provided
externally to the CPU controller (currently usage_usec), so if we have a
new enough kernel, we don't need to set CGROUP_MASK_CPU for
CPUAccounting=true as the CPU controller does not need to necessarily be
enabled in this case.
Part of this patch is modelled on an earlier patch by Ryutaroh Matsumoto
(see PR #9665).
It's possible for sscanf to receive strings containing all three fields
and not matching the template at the same time. When this happens the
value of k doesn't change, which basically means that process_audit_string
tries to access memory randomly. Sometimes it works and sometimes it doesn't :-)

This removes the ability to configure which cgroup controllers to mount
together. Instead, we'll now hardcode that "cpu" and "cpuacct" are
mounted together as well as "net_cls" and "net_prio".
The concept of mounting controllers together has no future as it does
not exist to cgroupsv2. Moreover, the current logic is systematically
broken, as revealed by the discussions in #10507. Also, we surveyed Red
Hat customers and couldn't find a single user of the concept (which
isn't particularly surprising, as it is broken...)
This reduced the (already way too complex) cgroup handling for us, since
we now know whenever we make a change to a cgroup for one controller to
which other controllers it applies.
Fedora Rawhide renamed dbus.service to dbus-daemon.service - that
breaks tests which require working DBus (e.g. TEST-03-JOBS)
Excerpt from the dbus.spec:
The 'dbus' package is only retained for compatibility purposes. It will
eventually be removed and then replaced by 'Provides: dbus' in the
dbus-daemon package. It will then exclusively be used for other packages to
describe their dependency on a system and user bus. It does not pull in any
particular dbus *implementation*, nor any libraries. These should be pulled
in, if required, via explicit dependencies.
Unfortunately we can't check the 6rd attribute, because it's not
exposed in /sys or anywhere other than netlink... But at least we
can check that networkd brings up an interface that looks right.
