As described in https://golang.org/s/generatedcode, Go has
a formalized format that should be used to indicate that a
file is generated.
Matching that format helps linters to skip generated files;
From https://golang.org/s/generatedcode (https://github.com/golang/go/issues/13560#issuecomment-288457920);
> Generated files are marked by a line of text that matches the regular expression, in Go syntax:
>
> ^// Code generated .* DO NOT EDIT\.$
>
> The `.*` means the tool can put whatever folderol it wants in there, but the comment
> must be a single line and must start with `Code generated` and end with `DO NOT EDIT.`,
> with a period.
>
> The text may appear anywhere in the file.
This patch updates the template used for our generated types
to match that format.

This commit adds the image variant to the image.(Image) type and
updates related functionality. Images built from another will
inherit the OS, architecture and variant.
Note that if a base image does not specify an architecture, the
local machine's architecture is used for inherited images. On the
other hand, the variant is set equal to the parent image's variant,
even when the parent image's variant is unset.
The legacy builder is also updated to allow the user to specify
a '--platform' argument on the command line when creating an image
FROM scratch. A complete platform specification, including variant,
is supported. The built image will include the variant, as will any
derived images.

Commit 77b8465d7e added a secret update
endpoint to allow updating labels on existing secrets. However, when
implementing the endpoint, the DebugRequestMiddleware was not updated
to scrub the Data field (as is being done when creating a secret).
When updating a secret (to set labels), the Data field should be either
`nil` (not set), or contain the same value as the existing secret. In
situations where the Data field is set, and the `dockerd` daemon is
running with debugging enabled / log-level debug, the base64-encoded
value of the secret is printed to the daemon logs.
The docker cli does not have a `docker secret update` command, but
when using `docker stack deploy`, the docker cli sends the secret
data both when _creating_ a stack, and when _updating_ a stack, thus
leaking the secret data if the daemon runs with debug enabled:
1. Start the daemon in debug-mode
dockerd --debug
2. Initialize swarm
docker swarm init
3. Create a file containing a secret
echo secret > my_secret.txt
4. Create a docker-compose file using that secret
cat > docker-compose.yml <<'EOF'
version: "3.3"
services:
web:
image: nginx:alpine
secrets:
- my_secret
secrets:
my_secret:
file: ./my_secret.txt
EOF
5. Deploy the stack
docker stack deploy -c docker-compose.yml test
6. Verify that the secret is scrubbed in the daemon logs

7. Re-deploy the stack to trigger an "update"
docker stack deploy -c docker-compose.yml test
8. Notice that this time, the Data field is not scrubbed, and the base64-encoded secret is logged

This patch modifies `maskSecretKeys` to unconditionally scrub `Data` fields.
Currently, only the `secrets` and `configs` endpoints use a field with this
name, and no other POST API endpoints use a data field, so scrubbing this
field unconditionally will only scrub requests for those endpoints.
If a new endpoint is added in future where this field should not be scrubbed,
we can re-introduce more fine-grained (path-specific) handling.
This patch introduces some change in behavior:
- In addition to secrets, requests to create or update _configs_ will
now have their `Data` field scrubbed. Generally, the actual data should
not be interesting for debugging, so likely will not be problematic.
In addition, scrubbing this data for configs may actually be desirable,
because (even though they are not explicitely designed for this purpose)
configs may contain sensitive data (credentials inside a configuration
file, e.g.).
- Requests that send key/value pairs as a "map" and that contain a
key named "data", will see the value of that field scrubbed. This
means that (e.g.) setting a `label` named `data` on a config, will
scrub/mask the value of that label.
- Note that this is already the case for any label named `jointoken`,
`password`, `secret`, `signingcakey`, or `unlockkey`.

Running a cluster in a two-manager configuration effectively *doubles*
the chance of loosing control over the cluster (compared to running
in a single-manager setup). Users may have the assumption that having

they're using this configuration.
This patch adds a warning to the `info` response if Swarm is configured
with two managers:

no fault tolerance, and poses a high risk to loose control over the cluster.

Also fixes https://github.com/moby/moby/issues/22874
This commit is a pre-requisite to moving moby/moby on Windows to using
Containerd for its runtime.
The reason for this is that the interface between moby and containerd
for the runtime is an OCI spec which must be unambigious.
It is the responsibility of the runtime (runhcs in the case of
containerd on Windows) to ensure that arguments are escaped prior
to calling into HCS and onwards to the Win32 CreateProcess call.
Previously, the builder was always escaping arguments which has
led to several bugs in moby. Because the local runtime in
libcontainerd had context of whether or not arguments were escaped,
it was possible to hack around in daemon/oci_windows.go with
knowledge of the context of the call (from builder or not).
With a remote runtime, this is not possible as there's rightly
no context of the caller passed across in the OCI spec. Put another
way, as I put above, the OCI spec must be unambigious.
The other previous limitation (which leads to various subtle bugs)
is that moby is coded entirely from a Linux-centric point of view.
Unfortunately, Windows != Linux. Windows CreateProcess uses a
command line, not an array of arguments. And it has very specific
rules about how to escape a command line. Some interesting reading
links about this are:
https://blogs.msdn.microsoft.com/twistylittlepassagesallalike/2011/04/23/everyone-quotes-command-line-arguments-the-wrong-way/https://stackoverflow.com/questions/31838469/how-do-i-convert-argv-to-lpcommandline-parameter-of-createprocesshttps://docs.microsoft.com/en-us/cpp/cpp/parsing-cpp-command-line-arguments?view=vs-2017
For this reason, the OCI spec has recently been updated to cater
for more natural syntax by including a CommandLine option in
Process.
What does this commit do?
Primary objective is to ensure that the built OCI spec is unambigious.
It changes the builder so that `ArgsEscaped` as commited in a
layer is only controlled by the use of CMD or ENTRYPOINT.
Subsequently, when calling in to create a container from the builder,
if follows a different path to both `docker run` and `docker create`
using the added `ContainerCreateIgnoreImagesArgsEscaped`. This allows
a RUN from the builder to control how to escape in the OCI spec.
It changes the builder so that when shell form is used for RUN,
CMD or ENTRYPOINT, it builds (for WCOW) a more natural command line
using the original as put by the user in the dockerfile, not
the parsed version as a set of args which loses fidelity.
This command line is put into args[0] and `ArgsEscaped` is set
to true for CMD or ENTRYPOINT. A RUN statement does not commit
`ArgsEscaped` to the commited layer regardless or whether shell
or exec form were used.
- Don't set `PidsLimit` when creating a container and
no limit was set (or the limit was set to "unlimited")
- Don't set `PidsLimit` if the host does not have pids-limit
support (previously "unlimited" was set).
- Do not generate a warning if the host does not have pids-limit
support, but pids-limit was set to unlimited (having no
limit set, or the limit set to "unlimited" is equivalent,
so no warning is nescessary in that case).
- When updating a container, convert `0`, and `-1` to
"unlimited" (`0`).

This changes the default ipc mode of daemon/engine to be private,
meaning the containers will not have their /dev/shm bind-mounted
from the host by default. The benefits of doing this are:
1. No leaked mounts. Eliminate a possibility to leak mounts into
other namespaces (and therefore unfortunate errors like "Unable to
remove filesystem for <ID>: remove /var/lib/docker/containers/<ID>/shm:
device or resource busy").
2. Working checkpoint/restore. Make `docker checkpoint`
not lose the contents of `/dev/shm`, but save it to
the dump, and be restored back upon `docker start --checkpoint`
(currently it is lost -- while CRIU handles tmpfs mounts,
the "shareable" mount is seen as external to container,
and thus rightfully ignored).
3. Better security. Currently any container is opened to share
its /dev/shm with any other container.
Obviously, this change will break the following usage scenario:
$ docker run -d --name donor busybox top
$ docker run --rm -it --ipc container:donor busybox sh
Error response from daemon: linux spec namespaces: can't join IPC
of container <ID>: non-shareable IPC (hint: use IpcMode:shareable
for the donor container)
The soution, as hinted by the (amended) error message, is to
explicitly enable donor sharing by using --ipc shareable:
$ docker run -d --name donor --ipc shareable busybox top
Compatibility notes:
1. This only applies to containers created _after_ this change.
Existing containers are not affected and will work fine
as their ipc mode is stored in HostConfig.
2. Old backward compatible behavior ("shareable" containers
by default) can be enabled by either using
`--default-ipc-mode shareable` daemon command line option,
or by adding a `"default-ipc-mode": "shareable"`
line in `/etc/docker/daemon.json` configuration file.
3. If an older client (API < 1.40) is used, a "shareable" container
is created. A test to check that is added.

Monitoring systems and load balancers are usually configured to use HEAD
requests for health monitoring. The /_ping endpoint currently does not
support this type of request, which means that those systems have fallback
to GET requests.
This patch adds support for HEAD requests on the /_ping endpoint.
Although optional, this patch also returns `Content-Type` and `Content-Length`
headers in case of a HEAD request; Refering to RFC 7231, section 4.3.2:
The HEAD method is identical to GET except that the server MUST NOT
send a message body in the response (i.e., the response terminates at
the end of the header section). The server SHOULD send the same
header fields in response to a HEAD request as it would have sent if
the request had been a GET, except that the payload header fields
(Section 3.3) MAY be omitted. This method can be used for obtaining
metadata about the selected representation without transferring the
representation data and is often used for testing hypertext links for
validity, accessibility, and recent modification.
A payload within a HEAD request message has no defined semantics;
sending a payload body on a HEAD request might cause some existing
implementations to reject the request.
The response to a HEAD request is cacheable; a cache MAY use it to
satisfy subsequent HEAD requests unless otherwise indicated by the
Cache-Control header field (Section 5.2 of [RFC7234]). A HEAD
response might also have an effect on previously cached responses to
GET; see Section 4.3.5 of [RFC7234].
With this patch applied, either `GET` or `HEAD` requests work; the only
difference is that the body is empty in case of a `HEAD` request;

`time.After` keeps a timer running until the specified duration is
completed. It also allocates a new timer on each call. This can wind up
leaving lots of uneccessary timers running in the background that are
not needed and consume resources.
Instead of `time.After`, use `time.NewTimer` so the timer can actually
be stopped.
In some of these cases it's not a big deal since the duraiton is really
short, but in others it is much worse.

This fix add MemoryKernelTCP to HostConfig, and pass
the config to runtime-spec.
Additional test case has been added.
This fix fixes 37038.

This commit contains changes to configure DataPathPort
option. By default we use 4789 port number. But this commit
will allow user to configure port number during swarm init.
DataPathPort can't be modified after swarm init.

Adds support for sysctl options in docker services.
* Adds API plumbing for creating services with sysctl options set.
* Adds swagger.yaml documentation for new API field.
* Updates the API version history document.
* Changes executor package to make use of the Sysctls field on objects
* Includes integration test to verify that new behavior works.
Essentially, everything needed to support the equivalent of docker run's
`--sysctl` option except the CLI.
Includes a vendoring of swarmkit for proto changes to support the new
behavior.

This should eliminate a bunch of new (go-1.11 related) validation
errors telling that the code is not formatted with `gofmt -s`.
No functional change, just whitespace (i.e.
`git show --ignore-space-change` shows nothing).

When requesting information about the daemon's configuration through the `/info`
endpoint, missing features (or non-recommended settings) may have to be presented
to the user.
Detecting these situations, and printing warnings currently is handled by the
cli, which results in some complications:
- duplicated effort: each client has to re-implement detection and warnings.
- it's not possible to generate warnings for reasons outside of the information
returned in the `/info` response.
- cli-side detection has to be updated for new conditions. This means that an
older cli connecting to a new daemon may not print all warnings (due to
it not detecting the new conditions)
- some warnings (in particular, warnings about storage-drivers) depend on
driver-status (`DriverStatus`) information. The format of the information
returned in this field is not part of the API specification and can change
over time, resulting in cli-side detection no longer being functional.
This patch adds a new `Warnings` field to the `/info` response. This field is
to return warnings to be presented by the user.
Existing warnings that are currently handled by the CLI are copied to the daemon
as part of this patch; This change is backward-compatible with existing
clients; old client can continue to use the client-side warnings, whereas new
clients can skip client-side detection, and print warnings that are returned by
the daemon.
Example response with this patch applied;
```bash
curl --unix-socket /var/run/docker.sock http://localhost/info | jq .Warnings
```
```json
[
"WARNING: bridge-nf-call-iptables is disabled",
"WARNING: bridge-nf-call-ip6tables is disabled"
]

This feature allows user to specify list of subnets for global
default address pool. User can configure subnet list using
'swarm init' command. Daemon passes the information to swarmkit.
We validate the information in swarmkit, then store it in cluster
object. when IPAM init is called, we pass subnet list to IPAM driver.

* Expose license status in Info
This wires up a new field in the Info payload that exposes the license.

Although specs.Platform is desirable in the API, there is more work
to be done on helper functions, namely containerd's platforms.Parse
that assumes the default platform of the Go runtime.
That prevents a client to use the recommended Parse function to
retrieve a specs.Platform object.
With this change, no parsing is expected from the client.

This adds MaskedPaths and ReadOnlyPaths options to HostConfig for containers so

Adds functionality to parse and return network attachment spec
information. Network attachment tasks are phony tasks created in
swarmkit to deal with unmanaged containers attached to swarmkit. Before
this change, attempting `docker inspect` on the task id of a network
attachment task would result in an empty task object. After this change,
a full task object is returned

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

Docker daemon has a 16K buffer for log messages. If a message length
exceeds 16K, it should be split by the logger and merged at the
endpoint.
This change adds `PartialLogMetaData` struct for enhanced partial support
- LastPartial (bool) : indicates if this is the last of all partials.
- ID (string) : unique 32 bit ID. ID is same across all partials.
- Ordinal (int starts at 1) : indicates the position of msg in the series of partials.
Also, the timestamps across partials in the same.
