Let's support enumerating over devices that match all of the given
properties instead of any of the given properties by adding a new
function sd_device_enumerator_add_match_property_required() which
specifies properties that should all be matched instead of just one.
Fixes#28372
It might happen that a method call handler already generated an error
reply and then still propagated the error back to the varlink logic.
Let's not try to generate a 2nd reply from that error code then, but
simply proceed without. This simplifies handling of errors in method
call handlers, because they can uniformly return errno-style error
codes, and only if they want return a full Varlink errror.
Various Varlink calls only make sense if they are called with more=true
(i.e. in a mode where multiple replies are expected to be sent). If a
method call assumes it is called with more (manifested in the fact it
calls varlink_notify(), the call to reply to such messages) let's return
a recognizable error code for the violated expectation.
This adds a new error for this, org.varlink.service.ExpectedMore. Note
we are squatting the official org.varlink.service namespace, but for
such a basic thing it makes sense to add it there.
One of the steps in setting up NTP is to enable/disable the
'systemd-timesyncd.service' and then perform a daemon reload.
we use an extra-long timeout for reload in timedated as same as used in
systemd daemon reload to avoiding certain situation have longer reload
times (which exceed the 25 second default timeout used for
dbus-communication), potentially leading to setting NTP failure.
Let's show which fds are closed as part of the left-over fd set logic on
daemon reload/reexec cycles.
This is useful to debug accidentally unclaimed fds.
We have the "tasks.max" cgroup attribute only if we run in a cgroup
namespace, but not on the host. Hence let's handle ENODATA silently
simply to reduce the debug noise generated.
