Only umount it during cleanup if the $TESTDIR/root dir is a mountpoint.
This avoids adding noise to the stderr log such as:
mountpoint: /var/tmp/systemd-test.waLOFT/root: No such file or directory
To make debugging much easier, especially for crashes in tests under
QEMU, let's store the entire coredump bundle in the systemd journal,
which is usually kept around by various CIs. Right now, we usually end
up with a journal, but without the coredump itself, which is pretty
useless.
Otherwise, changing the default gateway doesn't purge old gateway routes
left on the system during daemon restart. This also fixes removing other
foreign gateway routes that don't match the expected configuration.
Tested:
Changed gateway addresses prior to the patch and they lingered on
the system during each reconfiguration. Applied this patch and
reconfigured gateways and other routes multiple times and it removed
the foreign routes that had gateways that didn't match.

The `coproc` implementation seems to be a little bit different in older
bash versions, so the `strace` is sometimes started AFTER `systemctl
daemon-reload`, which causes unexpected fails. Let's help it a little by
sleeping for a bit.
The MPOL_LOCAL constant is not recognized in current strace versions.
Let's match at least the numerical value of this constant until the
strace patch is approved & merged.
If networkctl crashes, like recently with SIGABRT, it returns absolutely
no output, which may be confusing during debugging. Help it a little
with a short informative message.
`adduser` is in certain cases a standalone package which provides a
better user experience. In other cases it's just a symlink to `useradd`.
And some distributions don't have `adduser` at all, like Arch Linux.
Let's use the `useradd` binary instead, which should provide the same
functionality everywhere.
This reworks how we load units from disk. Instead of chasing symlinks every
time we are asked to load a unit by name, we slurp all symlinks from disk
and build two hashmaps:
1. from unit name to either alias target, or fragment on disk
(if an alias, we put just the target name in the hashmap, if a fragment
we put an absolute path, so we can distinguish both).
2. from a unit name to all aliases
Reading all this data can be pretty costly (40 ms) on my machine, so we keep it
around for reuse.
The advantage is that we can reliably know what all the aliases of a given unit
are. This means we can reliably load dropins under all names. This fixes#11972.
I adjusted the tests to pass. I don't think the behaviour makes much sense,
even if we ignore the issue with "lazy loading" of aliases. E.g. in the
last section, the fact that dropins for yup@.service and yup@3.service are
not loaded seems to be a plain old bug.
This option is only used on reboot, not on other types of shutdown
modes, so it is misleading.
Keep the old name working for backward compatibility, but remove it
from the documentation.
Rather than always enabling the shutdown WD on kexec, which might be
dangerous in case the kernel driver and/or the hardware implementation
does not reset the wd on kexec, add a new timer, disabled by default,
to let users optionally enable the shutdown WD on kexec separately
from the runtime and reboot ones. Advise in the documentation to
also use the runtime WD in conjunction with it.
Fixes: a637d0f9ec ("core: set shutdown watchdog on kexec too")
It seems that old kernels do not support prefix routes with
non-default route tables. This adds a fallback logic when adding route
fails. In that case, prefix route is created by kernel and the default
route table is used.
Some distros install nologin as /usr/sbin/nologin, others as
/sbin/nologin.
Since we can't really on merged-usr everywhere (where the path wouldn't
matter), make the path build time configurable via -Dnologin-path=.
Closes#13028
without using -type f, the logs print an error such as:
E: E: modprobe: FATAL: Module asymmetric_keys not found in directory /lib/modules/4.15.0-54-generic
while this doesn't appear to cause problems, it can be extremely
distracting when trying to debug real failures.
Almost all tests were manually mounting/unmounting $TESTDIR/root
from the loopback image; this moves all that into test-functions
so the test setup functions are simplier.
Also add test_setup_cleanup() function, to cleanup what is mounted
by create_empty_image_rootdir()
Even if addresses provided by DHCP is assigned, the state file may not
be written yet, or resolved may not receive the state change signal
yet, or resolved may not process the signal yet...
Previously, event if link's setup state is in failed, tests may pass,
as systemd-networkd-wait-online success if the state is in failed state.
This makes tests be checked more strictly.
In Ubuntu CI, udev-test.pl is run from the debian/test/udev script,
in a test dir created for it; but udev-test.pl setup mounts a
dir, so if it doesn't cleanup/unmount before exiting, the test dir
autopkgtest created for it can't be removed, and autopkgtest
aborts the entire test suite, for example this output (from a
test run inside an armhf container):
autopkgtest [12:45:36]: test udev: [-----------------------

The `set -e` option is incompatible with a subshell/compound command,
which is followed by || <EXPR>. In such case, the -e option is ignored
in all affected subshells/functions (see man bash(1) for command `set`).
In certain cases we might attempt to install a binary which is already
present in the test image, yet it's missing from the host system.
In such cases, let's check if the binary indeed exists in the image
before doing any other chcecks. If it does, immediately return with
success.
This was discovered during installation of
/usr/lib/systemd/systemd-bless-boot, which was not present in Ubuntu CI
(as the installed systemd was from the Ubuntu repositories), and the
binary itself was already in the image thanks to `ninja install`.
However, during extraction of binaries from the systemd service files,
another attempt to install this binary was made, which failed due to
`find_binary` being unable to find it.
Before only one comparison was allowed. Let's make this more flexible:
ConditionKernelVersion = ">=4.0" "<=4.5"
Fixes#12881.
This also fixes expressions like "ConditionKernelVersion=>" which would
evaluate as true.
job_compare return value is undefined in case the jobs have a loop
between them, so better make a test to make sure transaction cycle
detection catches it.
The test-engine Test2 tests the cycle detection when units a, b and d
all start at once
,-------------------after-----------------,
v |
a/start ---after---> d/start ---after---> b/start
Extend the test with Test11 that adds i.service which causes a and d
stop (by unordered Conflicts=) while starting b. Because stops precede
starts, we effectively eliminate the job cycle and all transaction jobs
should be applicable.
,-------------------after-----------------,
v |
a/stop <---after--- d/stop <---after--- b/start

A class was used to put some utility functions under a namespace. But then this
namespace was inherited into classes, so the namespace split was undone. Let's
just define those functions in the module namespace.
(The Utilities class with a few functions still remain, because of the
unittest-style self.assert* craziness.)
For normal shell calls, python syntax is quite verbose. We don't need to punish
ourselves like that. In some places we would fork a shell to do argument splitting
for us. We know that our arguments can be safely split on whitespace, so let's do
that ourselves in all cases, without forking a shell.
We also expect command output to be valid text, so let's always set
universal_newlines=True.
This makes things shorter and easier to read. Development is also easier because
it's possible to paste many of the commands directly to/from a shell.
Adds the resumeflags= kernel command line option to allow setting a
custom device timeout for the resume device (defaults to the same as the
root device).
In certain situations, the systemctl commands may fail (e.g. due to
missing shared libraries), but the 'script' continues and creates a
/testok file, marking the test incorrectly as passed. Let's fix this and
bail out immediately when a command exits with a non-zero exit code.
Running integration tests with ASan is somewhat tricky to begin with, as
we need to pre-load the ASan runtime DSO for certain services (like
dbus), otherwise they won't start or behave as expected. In case of gcc
this is pretty easy, as we need the runtime DSO during compilation, so
it's already present on the host system. For clang things get more
complicated, as ASan is compiled in statically by default, thus to
enable the necessary dynamic-ish behavior one needs to compile with
-shared-libasan and then correctly set LD_PRELOAD_PATH, as the runtime
libraries are not in a standard library path.
These services are likely to coredump, and we expect that but aren't
interested in the coredump. Hence let's turn off processing by setting
RLIMIT_CORE to 0/0.
This patch adds netdev ipvtap that is based on the
IP-VLAN network interface, called ipvtap. An ipvtap device can be created
in the same way as an ipvlan device, using 'kind ipvtap', and then accessed
using the tap user space interface.
Certain distributions (e.g. Arch Linux) require booting with initrd, as
they lack support for commonly used filesystems in the kernel (i.e. the
support is compiled in as modules)
The `mount` utility has an unexpected behavior when run with libasan,
causing false-positives during the integration testing.
For example, on Arch Linux with LD_PRELOAD pointing to libasan:
```
bash-5.0# mount -o remount,rw -v /
mount: /dev/sda1 mounted on /.
bash-5.0# echo $?
1
```
However:
```
bash-5.0# LD_PRELOAD= mount -o remount,rw -v /
mount: /dev/sda1 mounted on /.
bash-5.0# echo $?
0
```
Further investigation with strace shows a LeakSanitizer error:
```
bash-5.0# strace -s 512 mount -o remount,rw -v /
...
write(2, "==355==LeakSanitizer has encountered a fatal error.\n", 52) = -1 EBADF (Bad file descriptor)
write(2, "ReportFile::Write() can't output requested buffer!\n", 51) = -1 EBADF (Bad file descriptor)
exit_group(1) = ?
+++ exited with 1 +++
```
Let's workaround this by clearing the LD_PRELOAD variable for
systemd-remount-fs.service
Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its
value from the IPv4 inner header. If the encapsulated protocol is IPv6 and
DF is configured to be inherited, always set it.
It makes more sense to call VXLAN ID as
1. the VXLAN Network Identifier (VNI) (or VXLAN Segment ID)
2. test-network: rename VXLAN Id to VNI
3. fuzzer: Add VXLAN VNI directive to fuzzer
