The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.
This patch moves our own uses of the package to use the new module.

Path prefixes were originally disallowed in the `--registry-mirrors`
option because the /v1 endpoint was assumed to be at the root of the
URI. This is no longer the case in v2.

The registry package contained code to automatically set the CertsDir() path,
based on wether or not the daemon was running in rootlessmode. In doing so,
it made use of the `pkg/rootless.RunningWithRootlessKit()` utility.
A recent change in de6732a403 added additional
functionality in the `pkg/rootless` package, introducing a dependency on
`github.com/rootless-containers/rootlesskit`. Unfortunately, the extra
dependency also made its way into the docker cli, which also uses the
registry package.
This patch introduces a new `SetCertsDir()` function, which allows
the default certs-directory to be overridden, and updates the daemon
to configure this location during startup.

The intent of this function is to return a copy of the service's configuration,
and to copy / dereference the options in its configuration.
The code was doing this in slightly complicated fashion. This patch;
- adds a `copy()` function to serviceConfig
- rewrites the code to use a slightly more idiomatic approach, using one of
the approaches described in "golang SliceTricks" https://github.com/golang/go/wiki/SliceTricks#copy
- changes defaultService.ServiceConfig() to use this function, and updates
its godoc to better describe that it returns a copy.

This removes the ugly hack where we stored the current config, tried to
reconfigure the service, and rolled back to the stored copy on failures.

This error was only returned in a single location, and not used anywhere
as a specific type.
The error returned by `validateNoScheme()` also appeared to only be used in
one case; in all other cases, the error itself was ignored, and replaced with
a custom error. Because of this, this patch also replace `validateNoScheme()`
with a `hasScheme()` function that returns a boolean, to better match how it's
used.

Un-export:

The config type is already un-exported; this also un-exports these functions
to be explicit they're internal only.

While this was intended t be a stop-gap solution, it's been there for years and
users depend on this. It's also still complicated to secure _localhost_, so
by now, we'd probably have to be realistic, and consider this to be "permanent".

This is more in line with other consts that are used for defaults, and makes it
slightly easier to consume than DefaultV2Registry, e.g. see:
https://github.com/oras-project/oras-go/blob/v1.1.0/pkg/auth/docker/resolver.go#L81-L84
Note that both the "index.docker.io" and "registry-1.docker.io" domains
are here for historic reasons and backward-compatibility. These domains
are still supported by Docker Hub (and will continue to be supported), but
there are new domains already in use, and plans to consolidate all legacy
domains to new "canonical" domains. Once those domains are decided on, we
should update these consts (but making sure to preserve compatibility with
existing installs, clients, and user configuration).

This header was used for fallbacks to v1 registries, but it's no longer
used, and marked optional / legacy in the OCI distribution-spec:

As people are using the UUID in `docker info` that was based on the v1 manifest signing key, replace

The --allow-nondistributable-artifacts daemon option specifies
registries to which foreign layers should be pushed. (By default,
foreign layers are not pushed to registries.)
Additionally, to make this option effective, foreign layers are now
pulled from the registry if possible, falling back to the URLs in the
image manifest otherwise.
This option is useful when pushing images containing foreign layers to a
registry on an air-gapped network so hosts on that network can pull the
images without connecting to another server.

This fix is based on:
https://github.com/docker/docker/issues/29936#issuecomment-277494885
Currently the insecure registry is only checked to see if it contains
scheme (`http(s)://`) or not. No fully validation is done and this
caused many confusions like in #29936.
This fix tries to address the issue.
This fix adds additional validation so that an insecure registry
is validated to make sure it is in `host:port` format where host
could be IPv4/IPv6 or a host name, and port could be an integer
between 0-65535.
Additional unit tests have been added.
This fix is related to #29936.

Remove forked reference package. Use normalized named values
everywhere and familiar functions to convert back to familiar
strings for UX and storage compatibility.
Enforce that the source repository in the distribution metadata
is always a normalized string, ignore invalid values which are not.
Update distribution tests to use normalized values.

While investigating 29936 I noticed one potential issue
in `LoadInsecureRegistries`.
The implementation of the func assumes that the format
of insecure registry should be `host:port` if not CIDR.
However, it is very common that user may incorrectly
provide a registry with a scheme (e.g, `http://myregistry.com:5000`)
Such a registry format with a scheme will cause docker pull to
always try https endpoint.
The reason is that the func of `isSecureIndex()` actually will
check for the map of the index server for `myregistry.com:5000`
while the insecure registry only has a record of `http://myregistry.com:5000`.
As a consequence, docker assumes that `myregistry.com:5000` is not
a insecure registry and will go ahead with https endpoint.
This fix addresses the issue by error out insecure registries with scheme.
A unit test has been added.
This fix is related to 29936.

All images in the default registry (AKA docker.io, index.docker.io, and
registry-1.docker.io) are available via the v2 protocol, so there's no
reason to use the v1 protocol. Disabling it prevents useless fallbacks.

This fixes the hard coded restriction for non-linux platforms to v2 registries. Previously, the check was above the flag parsing, which would overwrite the hard coded value and prevent correct operation. This change also removes the related daemon flag from Windows to avoid confusion, as it has no meaning when the value is going to always be hard coded to true.

Going forward, Docker won't use a different default registry on Windows.
This changes Windows to use the standard Docker Hub registry as the
default registry.
There is a plan in place to migrate existing images from the Windows
registry to Hub's normal registry, in advance of the 1.11 release. In
the mean time, images on the Windows registry can be accessed by
prefixing them with `registry-win-tp3.docker.io/`.
