When reading logs, timestamps should always be presented in UTC. Unlike
the "json-file" and other logging drivers, the "local" logging driver
was using local time.

The daemon currently provides support for API versions all the way back
to v1.12, which is the version of the API that shipped with docker 1.0. On
Windows, the minimum supported version is v1.24.
Such old versions of the client are rare, and supporting older API versions
has accumulated significant amounts of code to remain backward-compatible
(which is largely untested, and a "best-effort" at most).
This patch updates the minimum API version to v1.24, which is the fallback
API version used when API-version negotiation fails. The intent is to start
deprecating older API versions, but no code is removed yet as part of this
patch, and a DOCKER_MIN_API_VERSION environment variable is added, which
allows overriding the minimum version (to allow restoring the behavior from
before this patch).
With this patch the daemon defaults to API v1.24 as minimum:

The `ContainerCreateConfig` and `ContainerRmConfig` structs are used for
options to be passed to the backend, and are not used in client code.
Thess struct currently is intended for internal use only (for example, the
`AdjustCPUShares` is an internal implementation details to adjust the container's
config when older API versions are used).
Somewhat ironically, the signature of the Backend has a nicer UX than that
of the client's `ContainerCreate` signature (which expects all options to
be passed as separate arguments), so we may want to update that signature
to be closer to what the backend is using, but that can be left as a future
exercise.
This patch moves the `ContainerCreateConfig` and `ContainerRmConfig` structs
to the backend package to prevent it being imported in the client, and to make
it more clear that this is part of internal APIs, and not public-facing.

I noticed this log being logged as an error, but the kill logic actually

BaseFS is not serialized and is lost after an unclean shutdown. Unmount
method in the containerd image service implementation will not work
correctly in that case.
This patch will allow Unmount to restore the BaseFS if the target is
still mounted.
The reason it works with graphdrivers is that it doesn't directly
operate on BaseFS. It uses RWLayer, which is explicitly restored
immediately as soon as container is loaded.

DNS config is a property of each adapter on Windows, thus we've a
dedicated `EndpointOption` for that.
The list of `EndpointOption` that should be applied to a given endpoint
is built by `buildCreateEndpointOptions`. This function contains a
seemingly flawed condition that adds the DNS config _iff_:
1. the network isn't internal ;
2. no ports are published / exposed through another sandbox endpoint ;
While 1. does make sense, there's actually no justification for 2.,
hence this commit remove this part of the condition.
This logic flaw has been made obvious by 0fd0e82, but it was originally
introduced by d1e0a78. Commit and PR comments don't mention why this is
done like so. Most probably, this was overlooked both by the original
author and the PR reviewers.

The `buildCreateEndpointOptions` does a lot of things to build the list
of `libnetwork.EndpointOption` from the `EndpointSettings` spec. To skip
ports-related options, an early return was put in the middle of that
function body.
Early returns are generally great, but put in the middle of a 150-loc
long function that does a lot, they're just a potential footgun. And I'm
the one who pulled the trigger in 052562f. Since this commit, generic
options won't be applied to endpoints if there's already one with
exposed/published ports. As a consequence, only the first endpoint can
have a user-defined MAC address right now.
Instead of moving up the code line that adds generic options, a better
change IMO is to move ports-related options, and the early-return gating
those options, to a dedicated func to make `buildCreateEndpointOptions`
slightly easier to read and reason about.
There was actually one oddity in the original
`buildCreateEndpointOptions`: the early-return also gates the addition
of `CreateOptionDNS`. These options are Windows-specific; a comment is
added to explain that. But the oddity is really: why are we checking if
an endpoint with exposed / published ports joined this sandbox to decide
whether we want to configure DNS server on the endpoint's adapter? Well,
this early-return was most probably overlooked by the original author
and by reviewers at the time these options were added (in commit d1e0a78)
Let's fix that in a follow-up commit.

The DirCopy() function in "graphdriver/copy/copy.go" has a special case for

Significantly speeds up vfs's copy of a BusyBox filesystem (which
consists mainly of hard links to a single binary), making moby's

When starting a daemon in debug mode (such as used in CI), many log-messages
are printed during startup. As a result, the log message indicating whether
graph-drivers or snapshotters are used may appear far separate from the
informational log about the daemon (and selected storage-driver).
The existing log-driver also unconditionally uses the legacy "graph-driver"
terminology, instead of the more generic "storage-driver".
This patch changes the log message shown during startup to use the generic
"graph-driver" as field, and adds a new field that indicates wheter we're
using snapshotters or graph-drivers.
Given that snapshotters will be the default at some point, an alternative
could be to include the _type_ of driver used, for example;
`io.containerd.snapshotter.v1`, which may continue to be relevant after
snapshotters become the default, and at which point (potentially) the
type of snapshotter becomes more relevant.

commit def549c8f6 passed through the context
to the daemon.ContainerStart function. As a result, restarting containers
no longer is an atomic operation, because a context cancellation could
interrupt the restart (between "stopping" and "(re)starting"), resulting
in the container being stopped, but not restarted.
Restarting a container, or more factually; making a successful request on
the `/containers/{id]/restart` endpoint, should be an atomic operation.
This patch uses a context.WithoutCancel for restart requests.
It's worth noting that daemon.containerStop already uses context.WithoutCancel,
so in that function, we'll be wrapping the context twice, but this should
likely not cause issues (just redundant for this code-path).
Before this patch, starting a container that bind-mounts the docker socket,
then restarting itself from within the container would cancel the restart
operation. The container would be stopped, but not started after that:
docker run -dit --name myself -v /var/run/docker.sock:/var/run/docker.sock docker:cli sh
docker exec myself sh -c 'docker restart myself'
docker ps -a

With this patch: the stop still cancels the exec, but does not cancel the
restart operation, and the container is started again:
docker run -dit --name myself -v /var/run/docker.sock:/var/run/docker.sock docker:cli sh
docker exec myself sh -c 'docker restart myself'

When the default bridge is disabled by setting dockerd's `--bridge=none`
option, the daemon still creates a sandbox for containers with no
network attachment specified. In that case `NetworkDisabled` will be set
to true.
However, currently the `releaseNetwork` call will early return if
NetworkDisabled is true. Thus, these sandboxes won't be deleted until
the daemon is restarted. If a high number of such containers are
created, the daemon would then take few minutes to start.

When the daemon process or the host running it is abruptly terminated,
the layer metadata file can become inconsistent on the file system.
Specifically, `link` and `lower` files may exist but be empty, leading
to overlay mounting errors during layer extraction, such as:

Fixes#18864, #20648, #33561, #40901.
[This GH comment][1] makes clear network name uniqueness has never been
enforced due to the eventually consistent nature of Classic Swarm
datastores:
> there is no guaranteed way to check for duplicates across a cluster of
> docker hosts.
And this is further confirmed by other comments made by @mrjana in that
same issue, eg. [this one][2]:
> we want to adopt a schema which can pave the way in the future for a
> completely decentralized cluster of docker hosts (if scalability is
> needed).
This decentralized model is what Classic Swarm was trying to be. It's
been superseded since then by Docker Swarm, which has a centralized
control plane.
To circumvent this drawback, the `NetworkCreate` endpoint accepts a
`CheckDuplicate` flag. However it's not perfectly reliable as it won't
catch concurrent requests.
Due to this design decision, API clients like Compose have to implement
workarounds to make sure names are really unique (eg.
docker/compose#9585). And the daemon itself has seen a string of issues
due to that decision, including some that aren't fixed to this day (for
instance moby/moby#40901):
> The problem is, that if you specify a network for a container using
> the ID, it will add that network to the container but it will then
> change it to reference the network by using the name.
To summarize, this "feature" is broken, has no practical use and is a
source of pain for Docker users and API consumers. So let's just remove
it for _all_ API versions.

The daemon would pass an EndpointCreateOption to set the interface MAC
address if the network name and the provided network mode were matching.
Obviously, if the network mode is a network ID, it won't work. To make
things worse, the network mode is never normalized if it's a partial ID.
To fix that: 1. the condition under what the container's mac-address is
applied is updated to also match the full ID; 2. the network mode is
normalized to a full ID when it's only a partial one.

While working on this code, I noticed that there's currently an issue
with userns enabled. When userns is enabled, joining another container's
namespace must also join its user-namespace.
However, a container can only be in a single user namespace, so if a
container joins namespaces from multiple containers, latter user-namespaces
overwrite former ones.
We must add validation for this, but in the meantime, add notes / todo's.

This function didn't need the whole container, only its ID, so let's
use that as argument. This also makes it consistent with getIpcContainer.
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
`Daemon.getPidContainer()` was wrapping the error-message with a message
("cannot join PID of a non running container") that did not reflect the
actual reason for the error; `Daemon.GetContainer()` could either return
an invalid parameter (invalid / empty identifier), or a "not found" error
if the specified container-ID could not be found.
In the latter case, we don't want to return a "not found" error through
the API, as this would indicate that the container we're _starting_ was
not found (which is not the case), so we need to convert the error into
an `errdefs.ErrInvalidParameter` (the container-ID specified for the PID
namespace is invalid if the container doesn't exist).
This logic is similar to what we do for IPC namespaces. which received
a similar fix in c3d7a0c603.
This patch updates the error-types, and moves them into the getIpcContainer
and getPidContainer container functions, both of which should return
an "invalid parameter" if the container was not found.
It's worth noting that, while `WithNamespaces()` may return an "invalid
parameter" error, the `start` endpoint itself may _not_ be. as outlined
in commit bf1fb97575, starting a container
that has an invalid configuration should be considered an internal server
error, and is not an invalid _request_. However, for uses other than
container "start", `WithNamespaces()` should return the correct error
to allow code to handle it accordingly.
