Changes the `Read` and `Write` error handling
logic to return the original error while closing
the connection. We still skip calling `handleEOF`
if already closing the connection.
Fixes the flaky `TestCloseWhileWriting` and
`TestCloseWhileReading` tests.

The daemon collects this information regardless if "debug" is
enabled. Print the debugging information if either the daemon,
or the client has debug enabled.
We should probably improve this logic and print any of these if
set (but some special rules are needed for file-descriptors, which
may use "-1".

The flag-set that was returned is a pointer to the command's Flags(), which
is in itself passed by reference (as it is modified / set up).
This patch removes the flags return, to prevent assuming it's different than
the command's flags.
While SetupRootCommand is exported, a search showed that it's only used internally,
so changing the signature should not be a problem.

This flag was kept separate from the other flags, because at the time, the
CLI code and Daemon code still used the same codebase, and shared some parts.
This option only applied to the `docker` CLI, and thus was kept separate when
migrating to Cobra in 0452ff5a4d
Now that this code is only used for the CLI (and plugins), we can move this
flag together with the other flags.

Add a const to allow documenting the environment variable in code. The location
of this const is a bit "unfortunate", due to CLI and Client-config to be spread
over the cli/config, cli/config/configfile, and docker/docker/client packages
(some options are for the client, others for the CLI), and some reorganizing
may be useful for easier consumption.

commit 8a30653ed5 introduced a sync.Once
to allow for the config-directory (and home-dir) to be looked up lazily
instead of in an `init()`.
However, the package-level `configDir` variable can be set through two
separate paths; implicitly (through `config.Dir()`), and explicitly,
through `config.SetDir()`. The existing code had no synchronisation for
this, which could lead to a potential race-condition (code requesting
`config.Dir()` and code setting a custom path through `config.SetDir()`).
This patch adds synchronisation by triggering the `sync.Once` as part of
`config.SetDir()` to prevent it being triggered later (overwriting the
value that was set). It also restores the `resetConfigDir()` utility that
was removed in 379122b033, to allow resetting
the `sync.Once` for this test.
In general, we should get rid of this package-level variable, and store
it as a config on the client (passing the option to locations where its
used instead).

support for kubernetes contexts was deprecated in docker 20.10 through
b639ea8b89, 0793f96394,
and 1d37fb3027, and removed altoghether in
23.0 through 193ede9b12.
This patch removes the remaining stubs for options that were deprecated
and no longer used.

More things to be done after this, to allow passing a custom user-agent,
but let's start with just using this utility.

go1.20.5 (released 2023-06-06) includes four security fixes to the cmd/go and
runtime packages, as well as bug fixes to the compiler, the go command, the
runtime, and the crypto/rsa, net, and os packages. See the Go 1.20.5 milestone
on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.20.5+label%3ACherryPickApproved
full diff: https://github.com/golang/go/compare/go1.20.4...go1.20.5
These minor releases include 3 security fixes following the security policy:
- cmd/go: cgo code injection
The go command may generate unexpected code at build time when using cgo. This
may result in unexpected behavior when running a go program which uses cgo.
This may occur when running an untrusted module which contains directories with
newline characters in their names. Modules which are retrieved using the go command,
i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e.
GO111MODULE=off, may be affected).
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-29402 and Go issue https://go.dev/issue/60167.
- runtime: unexpected behavior of setuid/setgid binaries
The Go runtime didn't act any differently when a binary had the setuid/setgid
bit set. On Unix platforms, if a setuid/setgid binary was executed with standard
I/O file descriptors closed, opening any files could result in unexpected
content being read/written with elevated prilieges. Similarly if a setuid/setgid
program was terminated, either via panic or signal, it could leak the contents
of its registers.
Thanks to Vincent Dehors from Synacktiv for reporting this issue.
This is CVE-2023-29403 and Go issue https://go.dev/issue/60272.
- cmd/go: improper sanitization of LDFLAGS
The go command may execute arbitrary code at build time when using cgo. This may
occur when running "go get" on a malicious module, or when running any other
command which builds untrusted code. This is can by triggered by linker flags,
specified via a "#cgo LDFLAGS" directive.
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-29404 and CVE-2023-29405 and Go issues https://go.dev/issue/60305 and https://go.dev/issue/60306.

3.18 doesn't look to play well with gotestsum, so sticking to

When passing a Dockerfile through stdin, it's not possible to specify the
name of the Dockerfile (using the `-f` option). When building with BuildKit
enabled, an error is already produced for this case, but the classic builder
silently ignored it.
This patch adds an error for this situation:
echo -e 'FROM busybox' | DOCKER_BUILDKIT=0 docker build -f some.Dockerfile -
DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
BuildKit is currently disabled; enable it by removing the DOCKER_BUILDKIT=0
environment-variable.
unable to prepare context: ambiguous Dockerfile source: both stdin and flag correspond to Dockerfiles

This error was only used in a single location, so no need to define a
package-level variable for this.
