This PR includes these optimize changes:
- Remove the dependency on the container engine.
The old code uses runc to generate config.json and
Docker to export rootfs, that will be heavy and need
additional dependency.
Using a fixed config for busybox image can avoid
the heavy processing above.
- Moved duplicate code to pkg/katatestutils package

cri-containerd project has been merged into containerd repo, and
we should not reference it any more in code and docs.

Display a pseudo path to the sandbox socket in the output of
`kata-runtime env` for those hypervisors that use Hybrid VSOCK.
The path is not a real path since the command does not create a sandbox.
The output includes a `{ID}` tag which would be replaced with the real
sandbox ID (name) when the sandbox was created.
This feature is only useful for agent tracing with the trace forwarder
where the configured hypervisor uses Hybrid VSOCK.
Note that the features required a new `setConfig()` method to be added
to the `hypervisor` interface. This isn't normally needed as the
specified hypervisor configuration passed to `setConfig()` is also
passed to `createSandbox()`. However the new call is required by
`kata-runtime env` to display the correct socket path for Firecracker.
The new method isn't wholly redundant for the main code path though as
it's now used by each hypervisor's `createSandbox()` call.

The 'quiet' kernel parameter can avoid guest kernel logs while booting,
which can reduce boot time.
Fix: #2820
Signed-off-by: Bo Chen <chen.bo@intel.com>
We will need to have console output from the guest only for debugging
purposes. As a result, we can turn-off both the serial and
virtio-console devices by default for better boot time.

The variable for 'name' in config-settings.go.in was previously
hardcoded as "kata". In e7c42fb it was changed to the runtime name,
which is "kata-runtime". Add a variable to specify a syslog identifier
for consistency for tests and documentation that use it.

This patch adds an option "disable_seccomp" to the config
hypervisor.clh, from which users can disable the `seccomp`
feature from Cloud Hypervisor when needed (for debugging purposes).
Fixes: #2782
Signed-off-by: Bo Chen <chen.bo@intel.com>
This patch enables the `seccomp` feature from Cloud Hypervisor which
provides fine-grained allowed syscalls for each of its worker
threads. It brings important security benefits, while would increase
memory footprint.

Bump containerd to v1.5.7 in order to bring in a fix for CVE-2021-41103,
"insufficiently restricted permissions ons plugins directories
(https://github.com/advisories/GHSA-c2h3-6mxw-7mvq)".
dependabot found a potential security vulnerability and raised a PR to
fix it. However, dependabot does not properly follows nor understands
the needed of our CIs (mainly related to formatting the PR and whatnot),
thus I'm re-raising it.

Our check for the IP family is working as long as we have either a
gateway or a destination IP. Some routes are missing both.
The RT netlink messages provide the IP family information for each
route, so we can carry that piece of information up to the guest. That
will allow for a more reliable route IP family determination.
Signed-off-by: Samuel Ortiz <s.ortiz@apple.com>
We need to be able to get the IP family from the netlink route meesages,
and the Route.Family field only got recently added to the netlink
package.
The update generates static check warnings about the call for
nethandler.Delete() being deprecated in favor of a Close() call instead.
So we include the s/Delete()/Close()/ change as part of this PR.

Reduce the cloud-hypervisor log level from `Debug` to `Info` when hypervisor
debug is enabled. This is required since `Debug` level:
- Is overkill for debugging hypervisor failures.
- Effectively hides the output from the guest kernel and userland: CLH
generates so much output that the output from the guest gets "lost in
the noise" (experiments show that for each full CLH debug message, at most
1 _byte_ of guest output is displayed).
