Currently, there's no way to restart the tasks of a service without
making an actual change to the service. This leads to us giving awkward
workarounds as in
https://github.com/docker/docker.github.io/pull/178/files, where we tell
people to scale a service up and down to restore balance, or make
unnecessary changes to trigger a restart.
This change adds a --force option to "docker service update", which
forces the service to be updated even if no changes require that.
Since rolling update parameters are respected, the user can use
"docker service --force" to do a rolling restart. For example, the
following is supported:
docker service update --force --update-parallelism 2 \
--update-delay 5s myservice
Since the default value of --update-parallelism is 1, the default
behavior is to restart the service one task at a time.

This adds support for two enhancements to swarm service rolling updates:
- Failure thresholds: In Docker 1.12, a service update could be set up
to either pause or continue after a single failure occurs. This adds
an --update-max-failure-ratio flag that controls how many tasks need to
fail to update for the update as a whole to be considered a failure. A
counterpart flag, --update-monitor, controls how long to monitor each
task for a failure after starting it during the update.
- Rollback flag: service update --rollback reverts the service to its
previous version. If a service update encounters task failures, or
fails to function properly for some other reason, the user can roll back
the update.
SwarmKit also has the ability to roll back updates automatically after
hitting the failure thresholds, but we've decided not to expose this in
the Docker API/CLI for now, favoring a workflow where the decision to
roll back is always made by an admin. Depending on user feedback, we may
add a "rollback" option to --update-failure-action in the future.

Unfortunately, `(f)` aka `(ps:\n:)` flag will not create an array when
there is only one line. The subsequent use of indexes will then affect
the string. This leads to `docker rmi <tab>` to complete on the header
line instead of nothing.
Therefore, for each use of `(f)`, we ensure that we have an extra new
line to be sure we get an array.

After building docker from the git repo, you can run
```
./contrib/mac-install-bundle.sh install
```
and this will tell Docker for Mac to look for a bundle at the current
path to run instead of the built in version of Docker. This will persist
until you do a factory reset or run
```
./contrib/mac-install-bundle.sh undo
```
A factory reset is advised to reset as a development Docker may break your
install.
The path must be a path that is shared with Docker for Mac so that the VM
can find it - nothing is installed into the image.
This is in `contrib/` as it is a best effort attempt to make it easier for
Docker for Mac users to test master or pull requests. If it breaks anything
a factory reset is your friend.

With the latest OL7.2, selinux policy that is shipped
might not be the latest for it to work or build with
selinux policy for docker-1.12.
To be able to achieve that here is what is done:
1. Added systemd_machined policy which is part of systemd.
2. Temporarily comment out unconfined_typebounds because the
current OL7's selinux doesn't have unconfineduser selinux policy,
to include this will be too much. Will revisit this once we have
updated the selinux policy.

Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.
This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.
The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:
```
$ docker service ps condescending_cori
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 13 minutes ago Running 6c6d232a5d0e

While testing #24510 I noticed that 32 bit syscalls were incorrectly being
blocked and we did not have a test for this, so adding one.
This is only tested on amd64 as it is the only architecture that
reliably supports 32 bit code execution, others only do sometimes.
There is no 32 bit libc in the buildpack-deps so we cannot build
32 bit C code easily so use the simplest assembly program which
just calls the exit syscall.

This changes the default behavior so that rolling updates will not
proceed once an updated task fails to start, or stops running during the
update. Users can use docker service inspect --pretty servicename to see
the update status, and if it pauses due to a failure, it will explain
that the update is paused, and show the task ID that caused it to pause.
It also shows the time since the update started.
A new --update-on-failure=(pause|continue) flag selects the
behavior. Pause means the update stops once a task fails, continue means
the old behavior of continuing the update anyway.
In the future this will be extended with additional behaviors like
automatic rollback, and flags controlling parameters like how many tasks
need to fail for the update to stop proceeding. This is a minimal
solution for 1.12.

There are currently problems with "swarm init" and "swarm join" when an
explicit --listen-addr flag is not provided. swarmkit defaults to
finding the IP address associated with the default route, and in cloud
setups this is often the wrong choice.
Introduce a notion of "advertised address", with the client flag
--advertise-addr, and the daemon flag --swarm-default-advertise-addr to
provide a default. The default listening address is now 0.0.0.0, but a
valid advertised address must be detected or specified.
If no explicit advertised address is specified, error out if there is
more than one usable candidate IP address on the system. This requires a
user to explicitly choose instead of letting swarmkit make the wrong
choice. For the purposes of this autodetection, we ignore certain
interfaces that are unlikely to be relevant (currently docker*).
The user is also required to choose a listen address on swarm init if
they specify an explicit advertise address that is a hostname or an IP
address that's not local to the system. This is a requirement for
overlay networking.
Also support specifying interface names to --listen-addr,
--advertise-addr, and the daemon flag --swarm-default-advertise-addr.
This will fail if the interface has multiple IP addresses (unless it has
a single IPv4 address and a single IPv6 address - then we resolve the
tie in favor of IPv4).
This change also exposes the node's externally-reachable address in
docker info, as requested by #24017.
Make corresponding API and CLI docs changes.

Fixes#23981
The selinux issue we are seeing in the report is related to the socket
file for docker and nothing else. By removing the socket docker starts
up correctly.
However, there is another motivation for removing socket activation from
docker's systemd files and that is because when you have daemons running
with --restart always whenever you have a host reboot those daemons
will not be started again because the docker daemon is not started by
systemd until a request comes into the docker API.
Leave it for deb based systems because everything is working correctly
for both socket activation and starting normally at boot.
