Always install all tests if install-tests is set to true, as they might
be useful for CI. This includes manual and unsafe tests. Install those
in subdirectories of /usr/lib/systemd/tests.
Fixes#6163.
Device is gone and most likely it will get garbage collected. However in
cases when it doesn't get gc'ed (because it is referenced by some
other unit, e.g. mount from fstab) we need to unset sysfs. This is
because when device appears next time, possibly, with different sysfs
path we need to update the sysfs path. Current code could end up caching
stale sysfs path forever.
In reality this is not a problem for normal disks (unless you swap them
during system runtime). However this issue causes failures to mount
filesystems on LVM where sysfs path depends on activation
order (i.e. logical volumes from volume group that is activated first
get assigned lower dm-X numbers and corresponding syspaths).
Fixes#6126.
When a DBus name is released, NameOwnerChanged signal contains an empty string
as new_owner. Commit bbc2908 changed interpretation of the empty string to a
valid name, which is not consistent with values that are sent by dbus-daemon.
As a side effect, this masks symptoms of systemd-logind dbus disconnections
(#2925) by completely restarting it so it can freshly reconnect to dbus.
For now, let's just special-case this in the sources. If more partition
types like this show up we should probably find some other solution.
Fixes: #5806
Recent systemd compiled in a build root which had libidn2-devel installed would
not run in the default installation root which had just libidn and did not have
libidn2. Since a8a2a0ed64 libidn2-devel (or equivalent) is installed in
the build root. Normally, since we install systemd in the installation root,
all dependencies that are needed for the compiled systemd to run are present,
but libidn2 is a new dependency, so the distro packages would just pull in
libidn, and not libidn2.
Temporily add libdn2 to explicitly specified Packages. We can remove that once
distro-compiled systemds have moved to libind2.
These buttons were added specifically for joysticks with lots of buttons, no
other device should be using them. See kernel commit
cf2f765f18960 "HID: handle joysticks with large number of buttons"
We only test for BTN_TRIGGER_HAPPY (an alias for BTN_TRIGGER_HAPPY1) here, a
device that sets buttons 2 and above but doesn't set 1 is considered buggy.

/var can be on a remote filesystem, thus hooking it to local-fs.target is not correct.
Also, only install the mount unit when machined is enabled, because
machined is the one managing the underlying device, and thus makes no
sense without machined.
Fixes#1175
Previously we'd propagate errors returned by user callbacks configured
in vtables back to the users only for method handlers and property
get/set handlers. This does the same for child enumeration and when we
check whether a fallback unit exists.
Without this the failure will be treated as a non-recoverable connection
error and result in connection termination.
Fixes: #6059
Three binaries would fail to link when ld.bfd was used and link-udev-shared was
false. Add -pthreads (again) to the failing binaries and synchronize the
dependency list between libsystemd-shared .a and .so versions.
Apart from allowing the build to succeed, this shouldn't have much effect becuase
systemd-networkd was already using pthreads.
Fixes#5828.
Also called "ANSI-C Quoting" in info:(bash) ANSI-C Quoting.
The escaping rules are a POSIX proposal, and are described in
http://austingroupbugs.net/view.php?id=249. There's a lot of back-and-forth on
the details of escaping of control characters, but we'll be only using a small
subset of the syntax that is common to all proposals and is widely supported.
Unfortunately dash and fish and maybe some other shells do not support it (see
the man page patch for a list).
This allows environment variables to be safely exported using show-environment
and imported into the shell. Shells which do not support this syntax will have
to do something like
export $(systemctl show-environment|grep -v '=\$')
or whatever is appropriate in their case. I think csh and fish do not support
the A=B syntax anyway, so the change is moot for them.
Fixes#5536.
v2:
- also escape newlines (which currently disallowed in shell values, so this
doesn't really matter), and tabs (as $'\t'), and ! (as $'!'). This way quoted
output can be included directly in both interactive and noninteractive bash.
This is a fixup of commit a2df3ea4ae.
When there is a running job with JobRunningTimeoutSec= and systemd serializes
its state (e.g. during daemon-reload), the timer event source won't be properly
restored in job_coldplug().
Thus save and serialize begin_running_usec too and reinitialize the timer based
on that value.
This prevents udev from reading the data after freeing it.

We would write
[Slice]
CPUQuota=1844674407370955%
which is (numerically) correct, but it seems better to just write
[Slice]
CPUQuota=
which is interpreted as USEC_INFINITY by the parser in config_parse_cpu_quota().
Fixes#5965.
We open the target path with O_DIRECTORY|O_NOFOLLOW, and if that doesn't work,
we call unlink() on the path. In neither case we will follow the symlink, so
we can relax our check to also not follow symlinks.
Fixes#5864.
"-c", which is short for "--no-canonicalize", tells /bin/umount
that the path name is canonical (no .. or symlinks etc).
systemd always uses a canonical name, so this flag is appropriate
for systemd to use.
Knowing that the path is canonical allows umount to avoid
some calls to lstat() on the path.
From v2.30 "-c" goes further and causes umount to avoid all
attempts to 'lstat()' (or similar) the path. This is important
when automatically unmounting a filesystem, as lstat() can
hang indefinitely in some cases such as when an NFS server
is not accessible.
"-c" has been supported since util-linux 2.17 which is before the
earliest version supported by systemd.
So "-c" is safe to use now, and once util-linux v2.30 is in use,
it will allow mounts from non-responsive NFS servers to be
unmounted.
This prevents udev from double-freeing and crashing.

This adds /sys/firmware lookup for sysname when creating a new device,
which allows device-tree properties lookup. This look-up can then be
used in udev rules, allowing device-tree-based model detection.
