The NetworkMode "default" is now normalized into the value it
aliases ("bridge" on Linux and "nat" on Windows) by the
ContainerCreate endpoint, the legacy image builder, Swarm's
cluster executor and by the container restore codepath.
builder-next is left untouched as it already uses the normalized
value (ie. bridge).
Going forward, this will make maintenance easier as there's one
less NetworkMode to care about.

When this was called concurrently from the moby image
exporter there could be a data race where a layer was
written to the refs map when it was already there.
In that case the reference count got mixed up and on

The names of extended attributes are not completely freeform. Attributes
are namespaced, and the kernel enforces (among other things) that only
attributes whose names are prefixed with a valid namespace are
permitted. The name of the attribute therefore needs to be known in
order to diagnose issues with lsetxattr. Include the name of the
extended attribute in the errors returned from the Lsetxattr and
Lgetxattr so users and us can more easily troubleshoot xattr-related

The only use is in `builder/builder-next/adapters/snapshot.EnsureLayer()`,
which always calls the function with an _empty_ `oldTarDataPath`;
7082aecd54/builder/builder-next/adapters/snapshot/layer.go (L81)
When called with an empty `oldTarDataPath`, this function was an alias for
`checksumForGraphIDNoTarsplit`, so let's make it that.
Note that this code was added in 500e77bad0, as

The `ExecBackend.ContainerKill()` function was called before removing a build-
container.
This function is backed by `daemon.ContainerKill()` which, if no signal is passed,
performed a `daemon.Kill()`, using `SIGKILL` as signal. However, the
`ExecBackend.ContainerRm()` (backed by `daemonContainerRm()`), which is called
after this, is executed with the `ForceRemove` option set, which calls
`daemon.cleanupContainer()` with `ForceRemove` set, which also results in
`daemon.Kill()` being called:
1a0c15abbb/daemon/delete.go (L84-L95)
This makes the `ExecBackend.ContainerKill()` redundant, so removing this from
the interface.
While looking at this code, one (possible) race-condition was found in
`daemon.cleanupContainer()`, where `daemon.Kill()` could return a `errdefs.Conflict`
if the container was already stopped. An extra check was added for this case to
prevent `daemon.cleanupContainer()` from terminating early.

This was just a very thin wrapper for backend.ContainerRm(), and the
error it returned was not handled, so moving this code inline.
Moving it inline also allows differentiating the error message to
distinguish the "removing all intermediate containers" from "removing container"
(when cancelling a build).

This repository is not yet a module (i.e., does not have a `go.mod`). This
is not problematic when building the code in GOPATH or "vendor" mode, but
when using the code as a module-dependency (in module-mode), different semantics
are applied since Go1.21, which switches Go _language versions_ on a per-module,
per-package, or even per-file base.
A condensed summary of that logic [is as follows][1]:
- For modules that have a go.mod containing a go version directive; that
version is considered a minimum _required_ version (starting with the
go1.19.13 and go1.20.8 patch releases: before those, it was only a
recommendation).
- For dependencies that don't have a go.mod (not a module), go language
version go1.16 is assumed.
- Likewise, for modules that have a go.mod, but the file does not have a
go version directive, go language version go1.16 is assumed.
- If a go.work file is present, but does not have a go version directive,
language version go1.17 is assumed.
When switching language versions, Go _downgrades_ the language version,
which means that language features (such as generics, and `any`) are not
available, and compilation fails. For example:
# github.com/docker/cli/cli/context/store
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/storeconfig.go:6:24: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
/go/pkg/mod/github.com/docker/cli@v25.0.0-beta.2+incompatible/cli/context/store/store.go:74:12: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
Note that these fallbacks are per-module, per-package, and can even be
per-file, so _(indirect) dependencies_ can still use modern language
features, as long as their respective go.mod has a version specified.
Unfortunately, these failures do not occur when building locally (using
vendor / GOPATH mode), but will affect consumers of the module.
Obviously, this situation is not ideal, and the ultimate solution is to
move to go modules (add a go.mod), but this comes with a non-insignificant
risk in other areas (due to our complex dependency tree).
We can revert to using go1.16 language features only, but this may be
limiting, and may still be problematic when (e.g.) matching signatures
of dependencies.
There is an escape hatch: adding a `//go:build` directive to files that
make use of go language features. From the [go toolchain docs][2]:
> The go line for each module sets the language version the compiler enforces
> when compiling packages in that module. The language version can be changed
> on a per-file basis by using a build constraint.
>
> For example, a module containing code that uses the Go 1.21 language version
> should have a `go.mod` file with a go line such as `go 1.21` or `go 1.21.3`.
> If a specific source file should be compiled only when using a newer Go
> toolchain, adding `//go:build go1.22` to that source file both ensures that
> only Go 1.22 and newer toolchains will compile the file and also changes
> the language version in that file to Go 1.22.
This patch adds `//go:build` directives to those files using recent additions
to the language. It's currently using go1.19 as version to match the version
in our "vendor.mod", but we can consider being more permissive ("any" requires
go1.18 or up), or more "optimistic" (force go1.21, which is the version we
currently use to build).
For completeness sake, note that any file _without_ a `//go:build` directive
will continue to use go1.16 language version when used as a module.

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.
