Previously, we'd always generate a packet on the wire, even for names
that are within our local zone. Shortcut this, and always check the
local zone first. This should minimize generated traffic and improve
security.
Instead of taking a DnsQuestion object (i.e. an array of keys) only take
a single key. This simplifies things a bit, and as DNS/LLMNR require a
single question per query message was unnecessary anyway.
This mimics a similar change that was done a while ago for the dns cache
logic.
Now we don't support the socket protocol like
sctp and udplite .
This patch add a new config param
SocketProtocol: udplite/sctp
With this now we can configure the protocol as
udplite = IPPROTO_UDPLITE
sctp = IPPROTO_SCTP
Tested with nspawn:
journald: turn ForwardToSyslog= off by default
After all, rsyslog and friends nowadays read their data directly from
the journal, hence the forwarding is unnecessary in most cases.

Previously, after a timer unit elapsed we'd leave it around for good,
which has the nice benefit that starting a timer that shall trigger at a
specific point in time multiple times will only result in one trigger
instead of possibly many. With this change a new option
RemainAfterElapse= is added. It defaults to "true", to mimic the old
behaviour. If set to "false" timer units will be unloaded after they
elapsed. This is specifically useful for transient timer units.
We only reorder a few things and modernize some constructs. No
functional changes.
- Move some if checks from the caller to the callee of a few functions.
- Use IN_SE() where we can
- Move status printing functions together
Previously we used the process ID to generate transient unit names.
However, that is problematic as PIDs get reused easily, and applying
them to remote systems makes little sense.
Fortunately, each bus peer gets a unique, non-reusable ID assigned when
attaching to a bus, hence let's use that, if we can. In some cases we
cannot however, because we connect directly to PID's private socket, and
thus are not a proper bus peer with a unique ID. In that case generate a
random UUID to name the unit after.
manager_load_unit() will dispatch the load queue anyway, but let's make
sure we also dispatch it immediately, after truning a unit into a
transient one and loading the properties from the message. That way the
know about the validity of the unit before we begin processing the next
auxiliary unit.
Lets introduce unit_is_pristine() that verifies whether a unit is
suitable to become a transient unit, by checking that it is no
referenced yet and has no data on disk assigned.
Let's move the validation checks into the loop that sets up the main and
auxiliary transient units, so that we can generate pretty error messages
for all units a transient unit transaction generates, not just for the
main unit.
Don't block indefinitely, when control has been passed on from NDisc to DHCPv6.
In this case there is likely no IPv6 support on the local link, so otherwise
this would block indefinitely.
The ndisc client may trigger the dhcpv6 client to be started (this is the common case),
so we should allocate the dhcpv6 client whenever we allocate the ndisc one.
