Subject: [PATCH] core: do not spawn jobs or touch other units during
coldplugging
Because the order of coldplugging is not defined, we can reference a
not-yet-coldplugged unit and read its state while it has not yet been
set to a meaningful value.
This way, already active units may get started again.
We fix this by deferring such actions until all units have been at
least somehow coldplugged.

Subject: [PATCH] core: don't change removed devices to state "tentative"
Commit 628c89c introduced the "tentative" device state, which caused
devices to go from "plugged" to "tentative" on a remove uevent. This
breaks the cleanup of stale mounts (see commit 3b48ce4), as that only
applies to "dead" devices.
The "tentative" state only really makes sense on adding a device when
we don't know where it was coming from (i. e. not from udev). But when
we get a device removal from udev we definitively know that it's gone,
so change the device state back to "dead" as before 628c89c.

Subject: [PATCH] core: rework device state logic
This change introduces a new state "tentative" for device units. Device
units are considered "plugged" when udev announced them, "dead" when
they are not available in the kernel, and "tentative" when they are
referenced in /proc/self/mountinfo or /proc/swaps but not (yet)
announced via udev.
This should fix a race when device nodes (like loop devices) are created
and immediately mounted. Previously, systemd might end up seeing the
mount unit before the device, and would thus pull down the mount because
its BindTo dependency on the device would not be fulfilled.

Subject: [PATCH] core, shared: in deserializing, match same files reached via
different paths
When dbus.socket is updated like this:
-ListenStream=/var/run/dbus/system_bus_socket
+ListenStream=/run/dbus/system_bus_socket
... and daemon-reload is performed, bad things happen.
During deserialization systemd does not recognize that the two paths
refer to the same named socket and replaces the socket file with a new
one. As a result, applications hang when they try talking to dbus.
Fix this by finding a match not only when the path names are equal, but
also when they point to the same inode.
In socket_address_equal() it is necessary to move the address size
comparison into the abstract sockets branch. For path name sockets the
comparison must not be done and for other families it is redundant
(their sizes are constant and checked by socket_address_verify()).
FIFOs and special files can also have multiple pathnames, so compare the
inodes for them as well. Note that previously the pathname checks used
streq_ptr(), but the paths cannot be NULL.
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1186018

Subject: [PATCH] nspawn: when connected to pipes for stdin/stdout, pass them
as-is to PID 1
Previously we always invoked the container PID 1 on /dev/console of the
container. With this change we do so only if nspawn was invoked
interactively (i.e. its stdin/stdout was connected to a TTY). In all other
cases we directly pass through the fds unmodified.
This has the benefit that nspawn can be added into shell pipelines.

Commit 3f93da987 accidentally dropped the "return 0" after detection of a
duplicate line. Put it back, to get back the documented and intended "first

Subject: [PATCH] unit: use weaker dependencies between mount and device units
in --user mode
When running in user mode unmounting of mount units when a device
vanishes is unlikely to work, and even if it would work is already done
by PID 1 anyway. HEnce, when creating implicit dependencies between
mount units and their backing devices, created a Wants= type dependency
in --user mode, but leave a BindsTo= dependency in --system mode.

Subject: sd-dhcp-client: use RFC4361-complient ClientID by default
In addition to the benefits listed in the RFC, this allows DHCP to work also in
case several interfaces share the same MAC address on the same link (IPVLAN).
Note that this will make the ClientID (so probably the assigned IP address)
change on upgrades. If it is desired to avoid that we would have to remember and
write back the ID (which the library supports, but networkd currently does not).
