| * libpod: improve heuristic to detect cgroupGiuseppe Scrivano2021-11-24
| | | | | | | | | | | | | | | | | | | | | | improve the heuristic to detect the scope that was created for the container. This is necessary with systemd running as PID 1, since it moves itself to a different sub-cgroup, thus stats would not account for other processes in the same container.

| * stats: get the memory limit from the specGiuseppe Scrivano2021-11-24
| | | | | | | | | | | | | | | | | | | | OCI runtimes may set the memory limits in different ways, e.g., crun creates a sub-cgroup where the limits are applied, while runc applies them directly on the created cgroup. Since there is standardization on the cgroup path to use, just use the limit specified in the spec file. Signed-off-by: Giuseppe Scrivano <gscrivan@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.

Also make sure to free assigned ips on an error to not leak them.

|\ \ | | | | | | Do not store the exit command in container config
| * | 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. This option will allow you to specify which defaults you don't want. --unsetenv-all will remove all default environment variables.

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.
