systemd[1]: Listening on Journal Audit Socket.
systemd[1]: Starting Journal Audit Socket.

The reason is that the job completes before the ->start() method returns

The same thing happens when stopping units.
Rather than fixing the order of the messages, let's just not emit the
Starting/Stopping message at all when the job completes instantaneously.

Older greeters, however, implement take-overs when they start sessions on

sd-bus: properly match ID changes
If the caller does not specify arg1 for NameOwnerChanged matches, we
really must take the ID from arg2 or arg3, if provided. They are
guaranteed to be identical to arg1 if either is supplied, but there is no
strict requiredment that arg1 is supplied. Hence, make sure to always
take the more restrictive match. Otherwise, we install rather wide
matches without anyone requiring them.

sd-bus: destination-matches cannot match NameOwnerChanged
Make sure we don't install NameOwnerChanged matches if the caller passed
a destination='' match (except if it is the broadcast address). Per spec,
all NameOwnerChanged signals are broadcasts.
Only the NameLost/NameAcquired signals are unicasts, but those are never
received through sd-bus. Instead, the bus-proxy synthesizes them and it
already installs proper matches for them.

sd-bus: fix invalid stack access on test-bus-marshal
Make sure we actually parse "unsigned long long" if we encode a uint64_t.
Otherwise, we will get random data from the stack.

bitmap: use external iterator
Reuse the Iterator object from hashmap.h and expose a similar API.
This allows us to do
{
Iterator i;
unsigned n;
BITMAP_FOREACH(n, b, i) {
Iterator j;
unsigned m;
BITMAP_FOREACH(m, b, j) {
...
}
}
}
without getting confused. Requested by David.

sd-bus: fix gvariant structure encoding
In gvariant, all fixed-size objects need to be sized a multiple of their
alignment. If a structure has only fixed-size members, it is required to
be fixed size itself. If you imagine a structure like (ty), you have an
8-byte member followed by an 1-byte member. Hence, the overall inner-size
is 9. The alignment of the object is 8, though. Therefore, the specs
mandates final padding after fixed-size structures, to make sure it's
sized a multiple of its alignment (=> 16).
On the gvariant decoder side, we already account for this in
bus_gvariant_get_size(), as we apply overall padding to the size of the
structure. Therefore, our decoder correctly skips such final padding when
parsing fixed-size structure.
On the gvariant encoder side, however, we don't account for this final
padding. This patch fixes the structure and dict-entry encoders to
properly place such padding at the end of non-uniform fixed-size
structures.
The problem can be easily seen by running:
$ busctl --user monitor
and
$ busctl call --user org.freedesktop.systemd1 / org.foobar foobar "(ty)" 777 8
The monitor will fail to parse the message and print an error. With this
patch applied, everything works fine again.
This patch also adds a bunch of test-cases to force non-uniform
structures with non-pre-aligned positions.
Thanks to Jan Alexander Steffens <jan.steffens@gmail.com> for spotting
this and narrowing it down to non-uniform gvariant structures. Fixes #597.

build: add convenience target 'build-sources'
This target allows to trigger a build of $(BUILT_SOURCES) manually. This
is handy if you tend to use 'make systemd-foobar' to directly build a
single binary. Those do not pull in $(BUILT_SOURCES), unfortunately. See
automake docs for that.

sd-bus: fix object tree to be deeper than 2 levels
So right now our object-tree is limited to 2 levels at most
('/' and '/foo/...../bar'). We never link any intermediate levels, even
though that was clearly the plan. Fix the bus_node_allocate() helper to
actually link all intermediate nodes, too, not just the root node.
This fixes a simple inverse ptr-diff bug.
The downside of this fix is that we clearly never tested (nor used) the
object tree in any way. The only reason that the introspection works is
that our enumerators shortcut the object tree.
Lets see whether that code actually works..
Thanks to: Nathaniel McCallum <nathaniel@themccallums.org>
..for reporting this. See #524 for an actual example code.

sd-device: never return NULL+0
It is highly confusing if a getter function returns 0, but the value is
set to NULL. This, right now, triggers assertions as code relies on the
returned values to be non-NULL.
Like with sd-bus-creds and friends, return 0 only if a value is actually
available.
Discussed with Tom, and actually fixes real bugs as in #512.

sd-boot: ignore missing /etc/machine-id
If /etc/machine-id is missing (eg., gold images), we should not fail
installing sd-boot. This is a perfectly fine use-case and we should simply
skip installing the default loader config in that case.
