containerd has two objects with regard to containers.
There is a "container" object which is metadata and a "task" which is
manging the actual runtime state.
When docker starts a container, it creartes both the container metadata
and the task at the same time. So when a container exits, docker deletes
both of these objects as well.
This ensures that if, on start, when we go to create the container metadata object
in containerd, if there is an error due to a name conflict that we go
ahead and clean that up and try again.

A git bundle allows us keep the same SHA, giving us the ability to
validate our patch against a known entity and allowing us to push
directly from our private forks to public forks without having to
re-apply any patches.

This avoids the corner case where `via` is not nil, but has a length of 0,
so the updated code does not panic in that situation.

@sw-pschmied originally post this in #38285
While looking through the Moby source code was found /proc/asound to be
shared with containers as read-only (as defined in
https://github.com/moby/moby/blob/master/oci/defaults.go#L128).
This can lead to two information leaks.
---
**Leak of media playback status of the host**
Steps to reproduce the issue:
- Listen to music/Play a YouTube video/Do anything else that involves
sound output
- Execute docker run --rm ubuntu:latest bash -c "sleep 7; cat
/proc/asound/card*/pcm*p/sub*/status | grep state | cut -d ' ' -f2 |
grep RUNNING || echo 'not running'"
- See that the containerized process is able to check whether someone
on the host is playing music as it prints RUNNING
- Stop the music output
- Execute the command again (The sleep is delaying the output because
information regarding playback status isn't propagated instantly)
- See that it outputs not running
**Describe the results you received:**
A containerized process is able to gather information on the playback
status of an audio device governed by the host. Therefore a process of a
container is able to check whether and what kind of user activity is
present on the host system. Also, this may indicate whether a container
runs on a desktop system or a server as media playback rarely happens on
server systems.
The description above is in regard to media playback - when examining
`/proc/asound/card*/pcm*c/sub*/status` (`pcm*c` instead of `pcm*p`) this
can also leak information regarding capturing sound, as in recording
audio or making calls on the host system.
