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:

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.
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.
One mention of --user was missing the surrounding <option> tag, making
the table look inconsistent (though the inconsistency is less obvious
after the reordering in 709f4c472c, since the four specifiers mentioning
the --user option are no longer immediately adjacent).
- Reset systemd-networkd.service before each test run, to avoid running
into restart limits.
- Our networkd-test-router.service unit needs to run as root and thus
can't use `User=`; but networkd still insists on the
`systemd-network` system user to exist, so create it.
There are some modern programming languages use userspace context switches
to implement coroutine features. PowerPC (32-bit) needs syscall "swapcontext" to get
contexts or switch between contexts, which is special.
Adding this rule should fix#9485.
The D-Bus library supplies a va_list variant of
`sd_bus_message_append()` called `sd_bus_message_appendv()`,
but failed to provide a va_list variant of its opposite,
`sd_bus_message_read()`. This commit publicizes a previously static
function as `sd_bus_message_readv()`.
