This enables picking up OTLP tracing context for the gRPC
requests.
Also sets up the in-memory recorder that BuildKit History API
can use to store the traces associated with specific build
in a database after build completes.
This doesn't enable Jaeger tracing endpoints from env
but this can be easily enabled by adding another import if
maintainers want it.

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.

daemon.generateNewName() already reserves the generated name, but its name
did not indicate it did. The daemon.registerName() assumed that the generated
name still had to be reserved, which could mean it would try to reserve the
same name again.
This patch renames daemon.generateNewName to daemon.generateAndReserveName
to make it clearer what it does, and updates registerName() to return early
if it successfully generated (and registered) the container name.

The most notable change here is that the OCI's type uses a pointer for `Created`, which we probably should've been too, so most of these changes are accounting for that (and embedding our `Equal` implementation in the one single place it was used).

This utility was only used in a single location (as part of `docker info`),
but the `pkg/rootless` package is imported in various locations, causing
rootlesskit to be a dependency for consumers of that package.
Move GetRootlessKitClient to the daemon code, which is the only location
it was used.

For configured runtimes with a runtimeType other than
io.containerd.runc.v1, io.containerd.runc.v2 and
io.containerd.runhcs.v1, the only supported way to pass configuration is
through the generic containerd "runtimeoptions/v1".Options type. Add a
unit test case which verifies that the options set in the daemon config
are correctly unmarshaled into the daemon's in-memory runtime config,
and that the map keys for the daemon config align with the ones used
when configuring cri-containerd (PascalCase, not camelCase or
snake_case).

When constructing the client, and setting the User-Agent, care must be
taken to apply the header in the right location, as custom headers can
be set in the CLI configuration, and merging these custom headers should
not override the User-Agent header.
This patch adds a dedicated `WithUserAgent()` option, which stores the
user-agent separate from other headers, centralizing the merging of
other headers, so that other parts of the (CLI) code don't have to be
concerned with merging them in the right order.

Some snapshotters (like overlayfs or zfs) can't mount the same
directories twice. For example if the same directroy is used as an upper
directory in two mounts the kernel will output this warning:
overlayfs: upperdir is in-use as upperdir/workdir of another mount, accessing files from both mounts will result in undefined behavior.
And indeed accessing the files from both mounts will result in an "No
such file or directory" error.
This change introduces reference counts for the mounts, if a directory
is already mounted the mount interface will only increment the mount
counter and return the mount target effectively making sure that the
filesystem doesn't end up in an undefined behavior.

Audit the OCI spec options used for Linux containers to ensure they are
less order-dependent. Ensure they don't assume that any pointer fields
are non-nil and that they don't unintentionally clobber mutations to the
spec applied by other options.

Many of the fields in LinuxResources struct are pointers to scalars for
some reason, presumably to differentiate between set-to-zero and unset
when unmarshaling from JSON, despite zero being outside the acceptable
range for the corresponding kernel tunables. When creating the OCI spec
for a container, the daemon sets the container's OCI spec CPUShares and
BlkioWeight parameters to zero when the corresponding Docker container
configuration values are zero, signifying unset, despite the minimum
acceptable value for CPUShares being two, and BlkioWeight ten. This has
gone unnoticed as runC does not distingiush set-to-zero from unset as it
also uses zero internally to represent unset for those fields. However,
kata-containers v3.2.0-alpha.3 tries to apply the explicit-zero resource
parameters to the container, exactly as instructed, and fails loudly.
The OCI runtime-spec is silent on how the runtime should handle the case
when those parameters are explicitly set to out-of-range values and
kata's behaviour is not unreasonable, so the daemon must therefore be in
the wrong.
Translate unset values in the Docker container's resources HostConfig to
omit the corresponding fields in the container's OCI spec when starting
and updating a container in order to maximize compatibility with
runtimes.

The daemon has made a habit of mutating the DefaultRuntime and Runtimes
values in the Config struct to merge defaults. This would be fine if it
was a part of the regular configuration loading and merging process,
as is done with other config options. The trouble is it does so in
surprising places, such as in functions with 'verify' or 'validate' in
their name. It has been necessary in order to validate that the user has
not defined a custom runtime named "runc" which would shadow the
built-in runtime of the same name. Other daemon code depends on the
runtime named "runc" always being defined in the config, but merging it
with the user config at the same time as the other defaults are merged
would trip the validation. The root of the issue is that the daemon has
used the same config values for both validating the daemon runtime
configuration as supplied by the user and for keeping track of which
runtimes have been set up by the daemon. Now that a completely separate
value is used for the latter purpose, surprising contortions are no
longer required to make the validation work as intended.
Consolidate the validation of the runtimes config and merging of the
built-in runtimes into the daemon.setupRuntimes() function. Set the
result of merging the built-in runtimes config and default default
runtime on the returned runtimes struct, without back-propagating it
onto the config.Config argument.

The existing runtimes reload logic went to great lengths to replace the
directory containing runtime wrapper scripts as atomically as possible
within the limitations of the Linux filesystem ABI. Trouble is,
atomically swapping the wrapper scripts directory solves the wrong
problem! The runtime configuration is "locked in" when a container is
started, including the path to the runC binary. If a container is
started with a runtime which requires a daemon-managed wrapper script
and then the daemon is reloaded with a config which no longer requires
the wrapper script (i.e. some args -> no args, or the runtime is dropped
from the config), that container would become unmanageable. Any attempts
to stop, exec or otherwise perform lifecycle management operations on
the container are likely to fail due to the wrapper script no longer
existing at its original path.
Atomically swapping the wrapper scripts is also incompatible with the
read-copy-update paradigm for reloading configuration. A handler in the
daemon could retain a reference to the pre-reload configuration for an
indeterminate amount of time after the daemon configuration has been
reloaded and updated. It is possible for the daemon to attempt to start
a container using a deleted wrapper script if a request to run a
container races a reload.
Solve the problem of deleting referenced wrapper scripts by ensuring
that all wrapper scripts are *immutable* for the lifetime of the daemon
process. Any given runtime wrapper script must always exist with the
same contents, no matter how many times the daemon config is reloaded,
or what changes are made to the config. This is accomplished by using
everyone's favourite design pattern: content-addressable storage. Each
wrapper script file name is suffixed with the SHA-256 digest of its
contents to (probabilistically) guarantee immutability without needing
any concurrency control. Stale runtime wrapper scripts are only cleaned
up on the next daemon restart.
Split the derived runtimes configuration from the user-supplied
configuration to have a place to store derived state without mutating
the user-supplied configuration or exposing daemon internals in API
struct types. Hold the derived state and the user-supplied configuration
in a single struct value so that they can be updated as an atomic unit.
