The initial version of libimage changed the order of layers which has
now been restored to remain backwards compatible.
Further changes:
* Fix a bug in the journald logging which requires to strip trailing
new lines from the message. The system tests did not pass due to
empty new lines. Triggered by changing the default logger to
journald in containers/common.
* Fix another bug in the journald logging which embedded the container
ID inside the message rather than the specifid field. That surfaced
in a preceeding whitespace of each log line which broke the system
tests.
* Alter the system tests to make sure that the k8s-file and the
journald logging drivers are executed.
* A number of e2e tests have been changed to force the k8s-file driver
to make them pass when running inside a root container.
* Increase the timeout in a kill test which seems to take longer now.
Reasons are unknown. Tests passed earlier and no signal-related
changes happend. It may be CI VM flake since some system tests but
other flaked.

died. This caused the container to lose network connectivity.
To fix this we have to start a new slirp4netns process.

Migrate the Podman code base over to `common/libimage` which replaces
`libpod/image` and a lot of glue code entirely.
Note that I tried to leave bread crumbs for changed tests.
Miscellaneous changes:
* Some errors yield different messages which required to alter some
tests.
* I fixed some pre-existing issues in the code. Others were marked as
`//TODO`s to prevent the PR from exploding.
* The `NamesHistory` of an image is returned as is from the storage.
Previously, we did some filtering which I think is undesirable.
Instead we should return the data as stored in the storage.
* Touched handlers use the ABI interfaces where possible.
* Local image resolution: previously Podman would match "foo" on
"myfoo". This behaviour has been changed and Podman will now
only match on repository boundaries such that "foo" would match
"my/foo" but not "myfoo". I consider the old behaviour to be a
bug, at the very least an exotic corner case.
* Futhermore, "foo:none" does *not* resolve to a local image "foo"
without tag anymore. It's a hill I am (almost) willing to die on.
* `image prune` prints the IDs of pruned images. Previously, in some
cases, the names were printed instead. The API clearly states ID,
so we should stick to it.
* Compat endpoint image removal with _force_ deletes the entire not
only the specified tag.

We originally added this in the *very early* days of Podman,
before a proper persistent state was written, so we had something
to test with. It was retained after the original SQLite state
(and current BoltDB state) were written so it could be used for
testing Libpod in unit tests with no requirement for on-disk
storage. Well, such unit tests never materialized, and if we were
to write some now the requirement to have a temporary directory
for storing data on disk is not that bad. I can basically
guarantee there are no users of this in the wild because, even if
you managed to figure out how to configure it when we don't
document it, it's completely unusable with Podman since all your
containers and pods will disappear every time Podman exits.

Podman has, for a long time, had an internal concept of
dependency management, used mainly to ensure that pod infra
containers are started before any other container in the pod. We
also have the ability to recursively start these dependencies,
which we use to ensure that `podman start` on a container in a
pod will not fail because the infra container is stopped. We have
not, however, exposed these via the command line until now.
Add a `--requires` flag to `podman run` and `podman create` to
allow users to manually specify dependency containers. These
containers must be running before the container will start. Also,
make recursive starting with `podman start` default so we can
start these containers and their dependencies easily.

One of the side-effects of the `--userns=keep-id` command is
switching the default user of the container to the UID of the
user running Podman (though this can still be overridden by the
`--user` flag). However, it did this by setting the UID and GID
in the OCI spec, and not by informing Libpod of its intention to
switch users via the `WithUser()` option. Because of this, a lot
of the code that should have triggered when the container ran
with a non-root user was not triggering. In the case of the issue
that this fixed, the code to remove capabilities from non-root
users was not triggering. Adjust the keep-id code to properly
inform Libpod of our intention to use a non-root user to fix
this.
Also, fix an annoying race around short-running exec sessions
where Podman would always print a warning that the exec session
had already stopped.

Instead of creating an extra container create a network and mount
namespace inside the podman user namespace. This ns is used to
for rootless cni operations.
This helps to align the rootless and rootful network code path.
If we run as rootless we just have to set up a extra net ns and
initialize slirp4netns in it. The ocicni lib will be called in
that net ns.
This design allows allows easier maintenance, no extra container
with pause processes, support for rootless cni with --uidmap
and possibly more.
The biggest problem is backwards compatibility. I don't think
live migration can be possible. If the user reboots or restart
all cni containers everything should work as expected again.
The user is left with the rootless-cni-infa container and image
but this can safely be removed.
To make the existing cni configs work we need execute the cni plugins
in a extra mount namespace. This ensures that we can safely mount over
/run and /var which have to be writeable for the cni plugins without
removing access to these files by the main podman process. One caveat
is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns`
accessible.
`XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`.
To ensure that we keep the netns directory we bind mount this relative
to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns
before we mount the run directory. The run directory is mounted recursive,
this makes the netns directory at the same path accessible as before.
This also allows iptables-legacy to work because /run/xtables.lock is
now writeable.

As part of a fix for an earlier bug (#5698) we added the ability
for Podman to chown volumes to correctly match the user running
in the container, even in adverse circumstances (where we don't
know the right UID/GID until very late in the process). However,
we only did this for volumes created automatically by a
`podman run` or `podman create`. Volumes made by
`podman volume create` do not get this chown, so their
permissions may not be correct. I've looked, and I don't think
there's a good reason not to do this chwon for all volumes the
first time the container is started.
I would prefer to do this as part of volume copy-up, but I don't
think that's really possible (copy-up happens earlier in the
process and we don't have a spec). There is a small chance, as
things stand, that a copy-up happens for one container and then
a chown for a second, unrelated container, but the odds of this
are astronomically small (we'd need a very close race between two
starting containers).

Traditionally, the path resolution for containers has been resolved on
the *host*; relative to the container's mount point or relative to
specified bind mounts or volumes.
While this works nicely for non-running containers, it poses a problem
for running ones. In that case, certain kinds of mounts (e.g., tmpfs)
will not resolve correctly. A tmpfs is held in memory and hence cannot
be resolved relatively to the container's mount point. A copy operation
will succeed but the data will not show up inside the container.
To support these kinds of mounts, we need to join the *running*
container's mount namespace (and PID namespace) when copying.
Note that this change implies moving the copy and stat logic into
`libpod` since we need to keep the container locked to avoid race
conditions. The immediate benefit is that all logic is now inside
`libpod`; the code isn't scattered anymore.
Further note that Docker does not support copying to tmpfs mounts.
Tests have been extended to cover *both* path resolutions for running
and created containers. New tests have been added to exercise the
tmpfs-mount case.
For the record: Some tests could be improved by using `start -a` instead
of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI
which forced me to use the more expensive start-exec option.

Instead of using the container's mountpoint as the base of the
chroot and indexing from there by the volume directory, instead
use the full path of what we want to copy as the base of the
chroot and copy everything in it. This resolves the bug, ends up
being a bit simpler code-wise (no string concatenation, as we
already have the full path calculated for other checks), and
seems more understandable than trying to resolve things on the
destination side of the copy-up.

Currently if the host shares container storage with a container
running podman, the podman inside of the container resets the
storage on the host. This can cause issues on the host, as
well as causes the podman command running the container, to
fail to unmount /dev/shm.
podman run -ti --rm --privileged -v /var/lib/containers:/var/lib/containers quay.io/podman/stable podman run alpine echo hello
* unlinkat /var/lib/containers/storage/overlay-containers/a7f3c9deb0656f8de1d107e7ddff2d3c3c279c11c1635f233a0bffb16051fb2c/userdata/shm: device or resource busy
* unlinkat /var/lib/containers/storage/overlay-containers/a7f3c9deb0656f8de1d107e7ddff2d3c3c279c11c1635f233a0bffb16051fb2c/userdata/shm: device or resource busy
Since podman is volume mounting in the graphroot, it will add a flag to
/run/.containerenv to tell podman inside of container whether to reset storage or not.
Since the inner podman is running inside of the container, no reason to assume this is a fresh reboot, so if "container" environment variable is set then skip
reset of storage.
Also added tests to make sure /run/.containerenv is runnig correctly.

This one is rather bizarre because it triggers only on some
systems. I've included a CI test, for example, but I'm 99% sure
we use images in CI that have volumes over empty directories, and
the earlier patch to change copy-up implementation passed CI
without complaint.
I can reproduce this on a stock F33 VM, but that's the only place
I have been able to see it.
Regardless, the issue: under certain as-yet-unidentified
environmental conditions, the copier.Get method will return an
ENOENT attempting to stream a directory that is empty. Work
around this by avoiding the copy altogether in this case.

Make sure that Podman's default OCI runtime is passed to Buildah in

defaults but the projects move at different speeds and it turns out
we caused a regression in v3.0.

Internally, Podman constructs a tree of layers in containers/storage to
quickly compute relations among layers and hence images. To compute the
tree, we intersect all local layers with all local images. So far,
lookup errors have been fatal which has turned out to be a mistake since
it seems fairly easy to cause storage corruptions, for instance, when
killing builds. In that case, a (partial) image may list a layer which
does not exist (anymore). Since the errors were fatal, there was no
easy way to clean up and many commands were erroring out.
To improve usability, turn the fatal errors into warnings that guide the
user into resolving the issue. In this case, a `podman system reset`
may be the approriate way for now.
[NO TESTS NEEDED] because I have no reliable way to force it.

When doing a container inspect on a container with unlimited ulimits,
the value should be -1. But because the OCI spec requires the ulimit
value to be uint64, we were displaying the inspect values as a uint64 as
well. Simple change to display as an int64.

The old copy-up implementation was very unhappy with symlinks,
which could cause containers to fail to start for unclear reasons
when a directory we wanted to copy-up contained one. Rewrite to
use the Buildah Copier, which is more recent and should be both
safer and less likely to blow up over links.
At the same time, fix a deadlock in copy-up for volumes requiring
mounting - the Mountpoint() function tried to take the
already-acquired volume lock.

Implement podman secret create, inspect, ls, rm
Implement podman run/create --secret
Secrets are blobs of data that are sensitive.
Currently, the only secret driver supported is filedriver, which means creating a secret stores it in base64 unencrypted in a file.
After creating a secret, a user can use the --secret flag to expose the secret inside the container at /run/secrets/[secretname]
This secret will not be commited to an image on a podman commit

When resolving the workdir of a container, we may need to create unless
the user set it explicitly on the command line. Otherwise, we just do a
presence check. Unfortunately, there was a missing return that lead us
to fall through into attempting to create and chown the workdir. That
caused a regression when running on a read-only root fs.

The allocated `tmpNetworkStatus` must be allocated with the length 0.
Otherwise append would add new elements to the end of the slice and
not at the beginning of the allocated memory.
This caused inspect to fail since the number of networks did not

The spec of a Kube Container has a `Command` and `Args`. While both are
slices, the `Command` is the counterpart of the entrypoint of a libpod
container. Kube is also happily accepting the arguments to as following
items in the slice but it's cleaner to move those to `Args`.

instead of using the --macvlan to indicate that you want to make a
macvlan network, podman network create now honors the driver name of
*macvlan*. Any options to macvlan, like the parent device, should be
specified as a -o option. For example, -o parent=eth0.
the --macvlan option was marked as deprecated in the man page but is
still supported for the duration of 3.0.

when creating kubernetes yaml from containers and pods, we should honor
any custom dns settings the user provided. in the case of generate kube,
these would be provided by --dns, --dns-search, and --dns-opt. if
multiple containers are involved in the generate, the options will be
cumulative and unique with the exception of dns-opt.
when replaying a kube file that has kubernetes dns information, we now
also add that information to the pod creation.
the options for dnspolicy is not enabled as there seemed to be no direct
correlation between kubernetes and podman.
