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.

Both of these were deprecated in 55f675811a,
but the format of the GoDoc comments didn't follow the correct format, which
caused them not being picked up by tools as "deprecated".

This update:
- removes support for go1.11
- removes the use of "golang.org/x/crypto/ed25519", which is now part of stdlib:
> Beginning with Go 1.13, the functionality of this package was moved to the

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.

Turned out that the loadOrCreateTrustKey() utility was doing exactly the
same as libtrust.LoadOrCreateTrustKey(), so making it a thin wrapped. I kept
the tests to verify the behavior, but we could remove them as we only need this
for our integration tests.
The storage location for the generated key was changed (again as we only need
this for some integration tests), so we can remove the TrustKeyPath from the
config.

This addresses a regression introduced in 407e3a4552,
which turned out to be "too strict", as there's old images that use, for example;
docker pull python:3.5.1-alpine
3.5.1-alpine: Pulling from library/python
unsupported media type application/octet-stream
Before 407e3a4552, such mediatypes were accepted;

This syncs the seccomp-profile with the latest changes in containerd's
profile, applying the same changes as 17a9324035
Some background from the associated ticket:
> We want to use vsock for guest-host communication on KubeVirt
> (https://github.com/kubevirt/kubevirt). In KubeVirt we run VMs in pods.
>
> However since anyone can just connect from any pod to any VM with the
> default seccomp settings, we cannot limit connection attempts to our
> privileged node-agent.
>
> ### Describe the solution you'd like
> We want to deny the `socket` syscall for the `AF_VSOCK` family by default.
>
> I see in [1] and [2] that AF_VSOCK was actually already blocked for some
> time, but that got reverted since some architectures support the `socketcall`
> syscall which can't be restricted properly. However we are mostly interested
> in `arm64` and `amd64` where limiting `socket` would probably be enough.
>
> ### Additional context
> I know that in theory we could use our own seccomp profiles, but we would want
> to provide security for as many users as possible which use KubeVirt, and there
> it would be very helpful if this protection could be added by being part of the
> DefaultRuntime profile to easily ensure that it is active for all pods [3].
>
> Impact on existing workloads: It is unlikely that this will disturb any existing
> workload, becuase VSOCK is almost exclusively used for host-guest commmunication.
> However if someone would still use it: Privileged pods would still be able to
> use `socket` for `AF_VSOCK`, custom seccomp policies could be applied too.
> Further it was already blocked for quite some time and the blockade got lifted
> due to reasons not related to AF_VSOCK.
>
> The PR in KubeVirt which adds VSOCK support for additional context: [4]
