16115b0a7b socket: introduce SELinuxContextFromNet option
This makes possible to spawn service instances triggered by socket with
MLS/MCS SELinux labels which are created based on information provided by
connected peer.

Implementation of label_get_child_mls_label derived from xinetd.

fb7661a602 man: use the escape for "-" in example instead of space.
This sentence can be misread to mean that "\x20" is the escape code for
"-" which is the only character explicitly mentioned. This lead to at
least one user loosing hair over why a mount unit for "/foo/bar-baz"
didn't work. The example escape is arbitrary so lets prevent hair loss.

8e3ba3772c udev: allow removing tags via TAG-="foobar"
This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.

This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.

84b5b79a8f networkd: allow specification of DHCP route metric
This lets the routing metric for links to be specified per-network,
still defaulting to DHCP_ROUTE_METRIC (1024) if unspecified. Hopefully
this helps with multiple interfaces configured via DHCP.

5019962312 bus: parse BusPolicy directive in service files
Add a new directive called BusPolicy to define custom endpoint policies. If
one such directive is given, an endpoint object in the service's ExecContext is
created and the given policy is added to it.

36f5ace2db man: reword sd-hibernate-resume description and add link
"each device" was suggesting that this service might be instantiated
multiple times. "hibernation resume" was too jargon-y.

d2c68822c4 hibernate-resume-generator: add a generator for instantiating the resume unit.
hibernate-resume-generator understands resume= kernel command line parameter
and instantiates the systemd-resume@.service accordingly if it is passed.

This enables resume from hibernation using device specified on the kernel
command line, and it may be specified either as "/dev/disk/by-foo/bar"
or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel
implementation.

So now resume= is brought on par with root= in terms of possible ways to
specify a device.

42483a7474 hibernate-resume: add a tool to write a device node's major:minor to /sys/power/resume.
This can be used to initiate a resume from hibernation by path to a swap
device containing the hibernation image.

The respective templated unit is also added. It is instantiated using
path to the desired resume device.

2928b0a863 core: add support for a configurable system-wide start-up timeout
When this system-wide start-up timeout is hit we execute one of the
failure actions already implemented for services that fail.

This should not only be useful on embedded devices, but also on laptops
which have the power-button reachable when the lid is closed. This
devices, when in a backpack might get powered on by accident due to the
easily reachable power button. We want to make sure that the system
turns itself off if it starts up due this after a while.

When the system manages to fully start-up logind will suspend the
machine by default if the lid is closed. However, in some cases we don't
even get as far as logind, and the boot hangs much earlier, for example
because we ask for a LUKS password that nobody ever enters.

Yeah, this is a real-life problem on my Yoga 13, which has one of those
easily accessible power buttons, even if the device is closed.

730836403a journalctl: add "-t --identifier=STRING" option
This turns journalctl to the counterpart of systemd-cat.
Messages sent with

systemd-cat --identifier foo --prioritiy debug

can now be shown with

journalctl --identifier foo --prioritiy debug

"--identifier" is not merged with "--unit" to make a clear
distinction between syslog and systemd units.
syslog identifiers can be chosen freely by anyone.

cc567c9bea socket: Add support for TCP defer accept
TCP_DEFER_ACCEPT Allow a listener to be awakened only when data
arrives on the socket. If TCP_DEFER_ACCEPT set on a server-side
listening socket, the TCP/IP stack will not to wait for the final
ACK packet and not to initiate the process until the first packet
of real data has arrived. After sending the SYN/ACK, the server will
then wait for a data packet from a client. Now, only three packets
will be sent over the network, and the connection establishment delay
will be significantly reduced.

tcp_keepalive_probes: The maximum number of TCP keep-alive probes to
send before giving up and killing the connection if no response is
obtained from the other end.

tcp_keepalive_time: The number of seconds a connection needs to be
idle before TCP begins sending out keep-alive probes.

9528592ff8 socket: add support for TCP fast Open
TCP Fast Open (TFO) speeds up the opening of successiveTCP)
connections between two endpoints.It works by using a TFO cookie
in the initial SYN packet to authenticate a previously connected
client. It starts sending data to the client before the receipt
of the final ACK packet of the three way handshake is received,
skipping a round trip and lowering the latency in the start of
transmission of data.
