* Unset SocketLabel after system finishes checkpointingDaniel J Walsh2021-11-23
| | | | | | | | | | | | This should fix the SELinux issue we are seeing with talking to /run/systemd/private. Fixes: https://github.com/containers/podman/issues/12362 Also unset the XDG_RUNTIME_DIR if set, since we don't know when running as a service if this will cause issue.s Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Warn on failing to update container statusMatthew Heon2021-11-23
| | | | | | | | | | | | | failed to send a signal to the container's PID1, but ignored the results of that update. That's generally bad practice, since even if we can't directly take action on an error, we should still make an effort to report it for debugging purposes. I used Infof instead of something more serious to avoid duplicate reporting to the user if something has gone seriously wrong. [NO NEW TESTS NEEDED] this is just adding additional error reporting.

| | | | | | | | | | | | | | | | | | When generating kube of a container, the podname and container name in the yaml are identical. This offends rules in podman where pods and containers cannot have the same name. We now append _pod to the podname to avoid that collision. Signed-off-by: Brent Baude <bbaude@redhat.com>
* | Fix netavark error handling and teardown issuePaul Holzinger2021-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The return error was not returned by podman , instead a different error was created. Also make sure to free assigned ips on an error to not leak them. Lastly podman container cleanup uses the default network backend instead of the provided one, we need to add `--network-backend` to the exit command.

| * | Do not store the exit command in container configPaul Holzinger2021-11-18
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem with creating and storing the exit command when the container was created. It only contains the options the container was created with but NOT the options the container is started with. One example would be a CNI network config. If I start a container once, then change the cni config dir with `--cni-config-dir` ans start it a second time it will start successfully. However the exit command still contains the wrong `--cni-config-dir` because it was not updated. To fix this we do not want to store the exit command at all. Instead we create it every time the conmon process for the container is startet. This guarantees us that the container cleanup process is startet with the correct settings.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The netns cleanup code is checking if there are running containers, this can fail if you run several libpod instances with diffrent root/runroot. To fix it we use one netns for each libpod instances. To prevent name conflicts we use a hash from the static dir as part of the name. Previously this worked because we would use the CNI files to check if the netns was still in use. but this is no longer possible with netavark.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman adds a few environment variables by default, and currently there is no way to get rid of them from your container.

The podman-machine cni plugin is no longer needed. The following new features are supported: - works with cni, netavark and slirp4netns - ports can use the hostIP to bind instead of hard coding 0.0.0.0 - gvproxy no longer listens on 0.0.0.0:7777 (requires a new gvproxy version) - support the udp protocol With this we no longer need podman-machine-cni and should remove it from the packaging. There is also a change to make sure we are backwards compatible with old config which include this plugin. Fixes #11528 Fixes #11728 [NO NEW TESTS NEEDED] We have no podman machine test at the moment. Please test this manually on your system. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

The network bucket also has a bucket for each subnet, the subnet is used as key. Inside the subnet bucket an ip is used as key and the container ID as value.
