The configDir (and "DOCKER_CONFIG" environment variable) is now only used
for the default location for TLS certificates to secure the daemon API.
It is a leftover from when the "docker" and "dockerd" CLI shared the same
binary, allowing the DOCKER_CONFIG environment variable to set the location
for certificates to be used by both.
This patch merges it into cmd/dockerd, which is where it was used.

The cli package is a leftover from when the "docker" and "dockerd" cli
were both maintained in this repository; the only consumer of this is
now the dockerd CLI, so we can move this code (it should not be imported
by anyone).

Moby is not a Go module; to prevent anyone from mistakenly trying to
convert it to one before we are ready, introduce a check (usable in CI
and locally) for a go.mod file.
This is preferable to trying to .gitignore the file as we can ensure
that a mistakenly created go.mod is surfaced by Git-based tooling and is
less likely to surprise a contributor.

To make the local build environment more correct and consistent, we
should never leave an uncommitted go.mod in the tree; however, we need a
go.mod for certain commands to work properly. Use a wrapper script to
create and destroy the go.mod as needed instead of potentially changing
tooling behavior by leaving it.
If a go.mod already exists, this script will warn and call the wrapped
command with GO111MODULE=on.

(*Daemon).registerLinks() calling the WriteHostConfig() method of its
container argument is a vestigial behaviour. In the distant past,
registerLinks() would persist the container links in an SQLite database
and drop the link config from the container's persisted HostConfig. This
changed in Docker v1.10 (#16032) which migrated away from SQLite and
began using the link config in the container's HostConfig as the
persistent source of truth. registerLinks() no longer mutates the
HostConfig at all so persisting the HostConfig to disk falls outside of
its scope of responsibilities.

(*Container).CheckpointTo() upserts a snapshot of the container to the
daemon's in-memory ViewDB and also persists the snapshot to disk. It
does not register the live container object with the daemon's container
store, however. The ViewDB and container store are used as the source of
truth for different operations, so having a container registered in one
but not the other can result in inconsistencies. In particular, the List
Containers API uses the ViewDB as its source of truth and the Container
Inspect API uses the container store.
The (*Daemon).setHostConfig() method is called fairly early in the
process of creating a container, long before the container is registered
in the daemon's container store. Due to a rogue CheckpointTo() call
inside setHostConfig(), there is a window of time where a container can
be included in a List Containers API response but "not exist" according
to the Container Inspect API and similar endpoints which operate on a
particular container. Remove the rogue call so that the caller has full
control over when the container is checkpointed and update callers to
checkpoint explicitly. No changes to (*Daemon).create() are needed as it
checkpoints the fully-created container via (*Daemon).Register().
Fixes#44512.

GetContainer() would return (nil, nil) when looking up a container
if the container was inserted into the containersReplica ViewDB but not
the containers Store at the time of the lookup. Callers which reasonably
assume that the returned err == nil implies returned container != nil
would dereference a nil pointer and panic. Change GetContainer() so that
it always returns a container or an error.

The List Images API endpoint has accepted multiple values for the
`since` and `before` filter predicates, but thanks to Go's randomizing
of map iteration order, it would pick an arbitrary image to compare
created timestamps against. In other words, the behaviour was undefined.
Change these filter predicates to have well-defined semantics: the
logical AND of all values for each of the respective predicates. As
timestamps are a totally-ordered relation, this is exactly equivalent to
applying the newest and oldest creation timestamps for the `since` and
`before` predicates, respectively.

Includes security fixes for net/http (CVE-2022-41717, CVE-2022-41720),
and os (CVE-2022-41720).
These minor releases include 2 security fixes following the security policy:
- os, net/http: avoid escapes from os.DirFS and http.Dir on Windows
The os.DirFS function and http.Dir type provide access to a tree of files
rooted at a given directory. These functions permitted access to Windows
device files under that root. For example, os.DirFS("C:/tmp").Open("COM1")
would open the COM1 device.
Both os.DirFS and http.Dir only provide read-only filesystem access.
In addition, on Windows, an os.DirFS for the directory \(the root of the
current drive) can permit a maliciously crafted path to escape from the
drive and access any path on the system.
The behavior of os.DirFS("") has changed. Previously, an empty root was
treated equivalently to "/", so os.DirFS("").Open("tmp") would open the
path "/tmp". This now returns an error.
This is CVE-2022-41720 and Go issue https://go.dev/issue/56694.
- net/http: limit canonical header cache by bytes, not entries
An attacker can cause excessive memory growth in a Go server accepting
HTTP/2 requests.
HTTP/2 server connections contain a cache of HTTP header keys sent by
the client. While the total number of entries in this cache is capped,
an attacker sending very large keys can cause the server to allocate
approximately 64 MiB per open connection.
This issue is also fixed in golang.org/x/net/http2 vX.Y.Z, for users
manually configuring HTTP/2.
Thanks to Josselin Costanzi for reporting this issue.

Kevin has been doing a lot of work helping modernize our CI, and helping
with BuildKit-related changes. Being our "resident GitHub actions expert",
I think it make sense to add him to the maintainers list as a curator (for
starters), to grant him permissions on the repository.
Perhaps we should nominate him to become a maintainer (with a focus on his
area of expertise) :)
