Fixes: #14846
Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
This addresses:
Symlinks don't work on podman machine on macOS Monterey when using volumes feature #13784
This change does NOT exactly fix the bug, but it does allow the user to
work around it via 'podman init' option, e.g.:
podman machine init -v "$HOME/git:$HOME/git:ro:security_model=none"
If the default security model were to be changed to 'none', then that
would fix the bug, at the possible cost of breaking any use cases that
depend on 'mapped-xattr'.
The documentation of the purpose and behavior of the different security
models seems to be rather light:
https://wiki.qemu.org/Documentation/9psetup#Starting_the_Guest_directly
From testing, it appears that the mapped-xattr security model intends to
manage symlinks such that the guest can see the symlinks but the host
only sees regular files (with extended attributes). As far as I can
tell, this behavior only makes sense when the guest is the only thing
that ever needs to create and read symlinks. Otherwise, symlinks created
on the host are unusable on the guest, and vice versa.
As per the original commit: 8e7eeaa4dd

Podman Machine crashes if run as root. When creating the machine, we write the ignition so that the UID of the core user matches the UID of the user on the host.

Libpod requires that all volumes are stored in the libpod db. Because
volume plugins can be created outside of podman, it will not show all
available plugins. This podman volume reload command allows users to
sync the libpod db with their external volume plugins. All new volumes
from the plugin are also created in the libpod db and when a volume from
the db no longer exists it will be removed if possible.
There are some problems:
- naming conflicts, in this case we only use the first volume we found.
This is not deterministic.
- race conditions, we have no control over the volume plugins. It is
possible that the volumes changed while we run this command.

Add the notion of an "exit policy" to a pod. This policy controls the
behaviour when the last container of pod exits. Initially, there are
two policies:
- "continue" : the pod continues running. This is the default policy
when creating a pod.
- "stop" : stop the pod when the last container exits. This is the
default behaviour for `play kube`.
In order to implement the deferred stop of a pod, add a worker queue to
the libpod runtime. The queue will pick up work items and in this case
helps resolve dead locks that would otherwise occur if we attempted to
stop a pod during container cleanup.
Note that the default restart policy of `play kube` is "Always". Hence,
in order to really solve #13464, the YAML files must set a custom
restart policy; the tests use "OnFailure".

add a new option to completely disable xfs quota usage for a volume.
xfs quota set on a volume, even just for tracking disk usage, can
cause weird errors if the volume is later re-used by a container with
a different quota projid. More specifically, link(2) and rename(2)
might fail with EXDEV if the source file has a projid that is
different from the parent directory.
To prevent such kind of issues, the volume should be created
beforehand with `podman volume create -o o=noquota $ID`

This is an enhancement proposal for the checkpoint / restore feature of
Podman that enables container migration across multiple systems with
standard image distribution infrastructure.
A new option `--create-image <image>` has been added to the
`podman container checkpoint` command. This option tells Podman to
create a container image. This is a standard image with a single layer,
tar archive, that that contains all checkpoint files. This is similar to
the current approach with checkpoint `--export`/`--import`.
This image can be pushed to a container registry and pulled on a
different system. It can also be exported locally with `podman image
save` and inspected with `podman inspect`. Inspecting the image would
display additional information about the host and the versions of
Podman, criu, crun/runc, kernel, etc.
`podman container restore` has also been extended to support image
name or ID as input.
