First: fix podman-registry script so it preserves the initial $PODMAN,
so all subsequent invocations of ps, logs, and stop will use the
same binary and arguments. Until now we've handled this by requiring
that our caller manage $PODMAN (and keep it the same), but that's
just wrong.
Next, simplify the golang interface: move the $PODMAN setting into
registry.go, instead of requiring e2e callers to set it. (This
could use some work: the local/remote conditional is icky).
IMPORTANT: To prevent registry.go from using the wrong podman binary,
the Start() call is gone. Only StartWithOptions() is valid now.
And, minor cleanup: comments, and add an actual error-message check
Reason for this PR is a recurring flake, #18355, whose multiple
failure modes I truly can't understand. I don't think this PR
is going to fix it, but this is still necessary work.

To debug a deadlock, we really want to know what lock is actually
locked, so we can figure out what is using that lock. This PR
adds support for this, using trylock to check if every lock on
the system is free or in use. Will really need to be run a few
times in quick succession to verify that it's not a transient
lock and it's actually stuck, but that's not really a big deal.

This is a general debug command that identifies any lock
conflicts that could lead to a deadlock. It's only intended for
Libpod developers (while it does tell you if you need to run
`podman system renumber`, you should never have to do that
anyways, and the next commit will include a lot more technical
info in the output that no one except a Libpod dev will want).
Hence, hidden command, and only implemented for the local driver
(recommend just running it by SSHing into a `podman machine` VM
in the unlikely case it's needed by remote Podman).
These conflicts should normally never happen, but having a
command like this is useful for debugging deadlock conditions
when they do occur.

There are quite a lot of places in podman were we have some signal
handlers, most notably libpod/shutdown/handler.go.
However when we rexec we do not want any of that and just send all
signals we get down to the child obviously. So before we install our
signal handler we must first reset all others with signal.Reset().
Also while at it fix a problem were the joinUserAndMountNS() code path
would not forward signals at all. This code path is used when you have
running containers but the pause process was killed.
Fixes#16091
Given that signal handlers run in different goroutines parallel it would
explain why it flakes sometimes in CI. However to my understanding this
flake can only happen when the pause process is dead before we run the
podman command. So the question still is what kills the pause process?

Add a new field `ExitCodePropagation` field to allow for configuring the
newly added functionality of controlling how the main PID of a kube
service exits.
Jira: issues.redhat.com/browse/RUN-1776
Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
Implement means for reflecting failed containers (i.e., those having
exited non-zero) to better integrate `kube play` with systemd. The
idea is to have the main PID of `kube play` exit non-zero in a
configurable way such that systemd's restart policies can kick in.
When using the default sdnotify-notify policy, the service container
acts as the main PID to further reduce the resource footprint. In that
case, before stopping the service container, Podman will lookup the exit
codes of all non-infra containers. The service will then behave
according to the following three exit-code policies:
- `none`: exit 0 and ignore containers (default)
- `any`: exit non-zero if _any_ container did
- `all`: exit non-zero if _all_ containers did
The upper values can be passed via a hidden `kube play
--service-exit-code-propagation` flag which can be used by tests and
later on by Quadlet.
In case Podman acts as the main PID (i.e., when at least one container
runs with an sdnotify-policy other than "ignore"), Podman will continue
to wait for the service container to exit and reflect its exit code.
Note that this commit also fixes a long-standing annoyance of the
service container exiting non-zero. The underlying issue was that the
service container had been stopped with SIGKILL instead of SIGTERM and
hence exited non-zero. Fixing that was a prerequisite for the exit-code
propagation to work but also improves the integration of `kube play`
with systemd and hence Quadlet with systemd.

the combination --pod and --userns is already blocked. Ignore the
PODMAN_USERNS variable when a pod is used, since it would cause to
create a new user namespace for the container.
Ideally a container should be able to do that, but its user namespace
must be a child of the pod user namespace, not a sibling. Since
nested user namespaces are not allowed in the OCI runtime specs,
disallow this case, since the end result is just confusing for the
user.

gvproxy listens on 127.0.0.1, using localhost as hostname can result in
the client trying to connect to the ipv6 localhost (`::1`). This will
fail as shown in the issue. This switches the hostname in the system
connection to 127.0.0.1 to fix this problem.
I switched the qemu, hyperV and WSL backend. I haven't touched the
applehv code because it uses two different ips and I am not sure what is
the correct thing there. I leave this to Brent to figure out.

These annotations can have security implications - crun, for
example, allows rootless containers to preserve the user's groups
through an annotation. We absolutely should not include
annotations from an untrusted image off the internet by default.
We may consider whitelisting some annotations (e.g. the legacy
WASM annotations), but given that there is now a more explicit
way of specifying an image uses the WASM runtime in the OCI image
spec, I'm just tearing this out entirely for now.

In rootFsSize(), instead of calculating the size of the diff for every
layer of the container's base image, ask the storage library for the sum
of the values it recorded when it first wrote those layers.
In a similar fashion, teach rwSize() to use the library's
ContainerSize() method instead of trying to roll its own.
Replace calls to pkg/util.SizeOfPath() with calls to
github.com/containers/storage/pkg/directory.Size(), which does the same
thing.
