* Network interfacePaul Holzinger2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new network interface to abstract CNI from libpod. The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.

* / | Implement SD-NOTIFY proxy in conmonDaniel J Walsh2021-08-20
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This leverages conmon's ability to proxy the SD-NOTIFY socket. This prevents locking caused by OCI runtime blocking, waiting for SD-NOTIFY messages, and instead passes the messages directly up to the host. NOTE: Also re-enable the auto-update tests which has been disabled due to flakiness. With this change, Podman properly integrates into systemd.

* Volumes: Only remove from DB if plugin removal succeedsMatthew Heon2021-08-18
| | | | | | | | | | | | | | | | | | Originally, Podman would unconditionally remove volumes from the DB, even if they failed to be removed from the volume plugin; this was a safety measure to ensure that `volume rm` can always remove a volume from the database, even if the plugin is misbehaving. However, this is a significant deivation from Docker, which refuses to remove if the plugin errors. These errors can be legitimate configuration issues which the user should address before the volume is removed, so Podman should also use this behaviour.

* | Fix rootless cni dns without systemd stub resolverPaul Holzinger2021-08-16
|/ | | | | | | | | | | | | | | | | When a host uses systemd-resolved but not the resolved stub resolver the following symlinks are created: `/etc/resolv.conf` -> `/run/systemd/resolve/stub-resolv.conf` -> `/run/systemd/resolve/resolv.conf`. Because the code uses filepath.EvalSymlinks we put the new resolv.conf to `/run/systemd/resolve/resolv.conf` but the `/run/systemd/resolve/stub-resolv.conf` link does not exists in the mount ns. To fix this we will walk the symlinks manually until we reach the first one under `/run` and use this for the resolv.conf file destination. This fixes a regression which was introduced in e73d4829900c. Fixes #11222 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | this is the first pass at implementing init containers for podman pods. init containersare made popular by k8s as a way to run setup for pods before the pods standard containers run. unlike k8s, we support two styles of init containers: always and oneshot. always means the container stays in the pod and starts whenever a pod is started. this does not apply to pods restarting. oneshot means the container runs onetime when the pod starts and then is removed.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To match Docker's behavior, in the `--net=host` case, we need to use the host's `/etc/hosts` file, unmodified (without adding an entry for the container). We will still respect hosts from `--add-host` but will not make any automatic changes. Fortuntely, this is strictly a matter of removal and refactoring as we already base our `/etc/hosts` on the host's version - just need to remove the code that added entries when net=host was set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman info takes >20s on Gentoo, because equery is s..l..o..w. qfile is much faster and, I suspect, present in most Gentoo installations, so let's try it first. And, because packageVersion() was scarily unmaintainable, refactor it. Define a simple (string) list of packaging tools to query (rpm, dpkg, ...) and iterate until we find one that works. IMPORTANT NOTE: the Debian (and, presumably, Ubuntu) query does not include version number! There is no standard way on Debian to get a package version from a file path, you can only do it via pipes of chained commands, and I have no desire to implement that.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rootlessport forwarder requires a child IP to be set. This must be a valid ip in the container network namespace. The problem is that after a network disconnect and connect the eth0 ip changed. Therefore the packages are dropped since the source ip does no longer exists in the netns. One solution is to set the child IP to 127.0.0.1, however this is a security problem. [1] To fix this we have to recreate the ports after network connect and disconnect. To make this work the rootlessport process exposes a socket where podman network connect/disconnect connect to and send to new child IP to rootlessport. The rootlessport process will remove all ports and recreate them with the new correct child IP. Also bump rootlesskit to v0.14.3 to fix a race with RemovePort().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support to checkpoint containers out of pods and restore container into pods. It is only possible to restore a container into a pod if it has been checkpointed out of pod. It is also not possible to restore a non pod container into a pod. The main reason this does not work is the PID namespace. If a non pod container is being restored in a pod with a shared PID namespace, at least one process in the restored container uses PID 1 which is already in use by the infrastructure container. If someone tries to restore container from a pod with a shared PID namespace without a shared PID namespace it will also fail because the resulting PID namespace will not have a PID 1.
