* Remove per-container CGroup parentsMatthew Heon2018-07-06
| | | | | | | | | | | | | | | | | | | Originally, it seemed like a good idea to place Conmon and the container it managed under a shared CGroup, so we could manage the two together. It's become increasingly clear that this is a potential performance sore point, gains us little practical benefit in managing Conmon, and adds extra steps to container cleanup that interfere with Conmon postrun hooks. Revert back to a shared CGroup for conmon processes under the CGroup parent. This will retain per-pod conmon CGroups as well if the pod is set to create a CGroup and act as CGroup parent for its containers.

* libpod/runtime_pod: Make removePod per-platformW. Trevor King2018-07-06
| | | | | | | | | | | | | | | | | | | | b96be3af (changes to allow for darwin compilation, 2018-06-20, #1015) made RemovePod per-platform, but left out docs for the unsupported version [1]: libpod/runtime_pod_unsupported.go:14:1:warning: exported method Runtime.RemovePod should have comment or be unexported (golint) To keep the docs DRY, I've restored RemovePod and its docs to their previous location, and named a new, internal removePod for the per-platform implementations.

| | | | | | | | | | | | | | | | | | This function was added in cc6f0e85 (more changes to compile darwin, 2018-07-04, #1047), but it has no consumers and no Linux analog. Remove it, which also fixes the [1]: libpod/networking_unsupported.go:9:1:warning: exported function JoinNetworkNameSpace should have comment or be unexported (golint) lint issue.

* more changes to compile darwinbaude2018-07-05
| | | | | | | | | | | | | | | | this should represent the last major changes to get darwin to **compile**. again, the purpose here is to get darwin to compile so that we can eventually implement a ci task that would protect against regressions for darwin compilation. i have left the manual darwin compilation largely static still and in fact now only interject (manually) two build tags to assist with the build. trevor king has great ideas on how to make this better and i will defer final implementation of those to him.

* libpod/container: Replace containerState* with containerPlatformStateW. Trevor King2018-07-05
| | | | | | | | | | | | | | | This way we don't need to stub in structures for other OSes (e.g. the Darwin stub in a Linux-only file). Matthew was concerned about errors unmarshalling, say, a Linux state object on a Windows box [1], but we can address that in checks when loading the database [2].

| | | | | | | | | | | | | The destination path of the built-in volume was not being created but a relabel was being attempted on it, this was causing issues with all images that have built-in volumes.

* Add `podman container cleanup` to CLIDaniel J Walsh2018-06-29
| | | | | | | | | | | | | When we run containers in detach mode, nothing cleans up the network stack or the mount points. This patch will tell conmon to execute the cleanup code when the container exits. It can also be called to attempt to cleanup previously running containers.

* Returning joining namespace error should not be fatalDaniel J Walsh2018-06-29
| | | | | | | | | | | | | | | | | | | | | | I got my database state in a bad way by killing a hanging container. It did not setup the network namespace correctly listing/remove bad containers becomes impossible. podman run alpine/nginx ^c got me in this state. I got into a state in the database where podman ps -a was returning errors and I could not get out of it, Makeing joining the network namespace a non fatal error fixes the issue.

* Errors from closing a netns on removal from DB are nonfatalMatthew Heon2018-06-19
| | | | | | | | | | | | | | | | Upon updating a container, if its network namespace has been removed, we attempt to clean up the network namespace locally, to ensure we don't leave hanging file descriptors. This triggers cleanup code which assumes the network namespace still exists, but it almost certainly was removed by whoever removed it from the database. As such, we end up with unavoidable errors if we don't want to leak FDs. Make these errors nonfatal and log them because of this.
