When unmounting user runtime directory, only UID is necessary,
and the corresponding user may not exist anymore.
This makes first try to parse the input by parse_uid(), and only if it
fails, prase the input by get_user_creds().
Fixes#9541.
When a slot is disconnected, then slot->match_callback.install_slot
is also disconnected. So, bus_slot_disconnect() removes the install_slot
from the list of slots in bus, although it is a floating object.
This makes install_slot unreffed from bus when it is disconnected.
Fixes#9505 and #9510.
The only known consumer of this property was libinput but it stopped using
this property since libinput 1.9 (released Oct 2017). This property is
arguably not one that should be in systemd anyway - it's not a
hardware-specific property but rather a factor of the acceleration method
employed by whatever userspace handles the events.
Deprecate it but leave the values in place for backwards compatibility.
The kernel added support for a new cgroup memory controller knob memory.min in
bf8d5d52ffe8 ("memcg: introduce memory.min") which was merged during v4.18
merge window.
Add MemoryMin to support memory.min.
This fixes the following valgrind warning:

If --dev-kvm-mode is set to something different then 0666, which we
explicitly support, it makes sense to still apply the uaccess tag to
/dev/kvm. For distros which opt to use the default 0666, this change is
a nop.
This partially reverts commit b8fd3d8220.
Mount tmpfses over the networkd and resolved config and state
directories, and stop the services beforehand. This ensures that the
test does not mess with an existing networkd/resolved setup. At least
for ethernet setups, this does not sever existing links, so is good
enough for the CI cases we are interested in (QEMU and LXC).
Relax the skip check to only skip the test when trying to run this on
real iron, but start running it in virtual machines now.
This allows us to run the test on Ubuntu 18.04 LTS in CI, which uses
both services by default.
Like s-networkd.service itself, it can happen that s-resolved.service
runs into restart limits. Don't enforce a successful call, as on
machines without resolved the unit might not be loaded.
Use <literallayout> to keep each reference on a separate line. With all the
pages jumbled together into a paragraph, it is quite hard to find anything in
that list.
Also add the missing pages to the list. And remove the nonexistent ones — not
much point in advertisting pages that haven't been written yet.
Prior to this commit, a .link file with a [Match] section containing
MACAddress= would match any device without a MAC. This restores the
matching logic prior to e90d037.
This is useful if someone wants to recreate the original syslog datagram. We
already include timestamp information as _SOURCE_REALTIME_TIMESTAMP=, and in
normal use that timestamp, converted back to the form used by syslog
(Mth dd HH:MM:SS) would usually give the value. But there are various
circumstances where this might not be true. Most obviously, if the datagram is
sent a bit later after being prepared, the time is rounded to the nearest
second, and it might be off. This is especially bad around New Year when the
syslog timestamp wraps around. Then the same timezone and locale need to be
used to recreate the original timestamp. In the end doing this reliably is
complicated, and it seems much easier to just unconditionally include the
original timestamp.
If the original timestamp cannot be located, we store the full log line.
This way, it should be always possible to recreate the original input.
Example:
MESSAGE=x
SYSLOG_TIMESTAMP=Sep 15 15:07:58
SYSLOG_RAW
^]^@^@^@^@^@^@^@<13>Sep 15 15:07:58 HOST: x^@y
_PID=3318
_SOURCE_REALTIME_TIMESTAMP=1530743976393553
Fixes#2398.
