* podman unshare: add --rootless-cni to join the nsPaul Holzinger2021-04-07
| | | | | | | | | | Add a new --rootless-cni option to podman unshare to also join the rootless-cni network namespace. This is useful if you want to connect to a rootless container via IP address. This is only possible from the rootless-cni namespace and not from the host namespace. This option also helps to debug problems in the rootless-cni namespace.

* rootless cni add /usr/sbin to PATH if not presentPaul Holzinger2021-04-06
| | | | | | | | | The CNI plugins need access to iptables in $PATH. On debian /usr/sbin is not added to $PATH for rootless users. This will break rootless cni completely. To prevent breaking existing users add /usr/sbin to $PATH in podman if needed. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman has, for a long time, had an internal concept of dependency management, used mainly to ensure that pod infra containers are started before any other container in the pod. We also have the ability to recursively start these dependencies, which we use to ensure that `podman start` on a container in a pod will not fail because the infra container is stopped. We have not, however, exposed these via the command line until now. Add a `--requires` flag to `podman run` and `podman create` to allow users to manually specify dependency containers. These containers must be running before the container will start. Also, make recursive starting with `podman start` default so we can start these containers and their dependencies easily.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the side-effects of the `--userns=keep-id` command is switching the default user of the container to the UID of the user running Podman (though this can still be overridden by the `--user` flag). However, it did this by setting the UID and GID in the OCI spec, and not by informing Libpod of its intention to switch users via the `WithUser()` option. Because of this, a lot of the code that should have triggered when the container ran with a non-root user was not triggering. In the case of the issue that this fixed, the code to remove capabilities from non-root users was not triggering. Adjust the keep-id code to properly inform Libpod of our intention to use a non-root user to fix this. Also, fix an annoying race around short-running exec sessions where Podman would always print a warning that the exec session had already stopped.

* | rootless cni without infra containerPaul Holzinger2021-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of creating an extra container create a network and mount namespace inside the podman user namespace. This ns is used to for rootless cni operations. This helps to align the rootless and rootful network code path. If we run as rootless we just have to set up a extra net ns and initialize slirp4netns in it. The ocicni lib will be called in that net ns. This design allows allows easier maintenance, no extra container with pause processes, support for rootless cni with --uidmap and possibly more. The biggest problem is backwards compatibility. I don't think live migration can be possible. If the user reboots or restart all cni containers everything should work as expected again. The user is left with the rootless-cni-infa container and image but this can safely be removed. To make the existing cni configs work we need execute the cni plugins in a extra mount namespace. This ensures that we can safely mount over /run and /var which have to be writeable for the cni plugins without removing access to these files by the main podman process. One caveat is that we need to keep the netns files at `XDG_RUNTIME_DIR/netns` accessible. `XDG_RUNTIME_DIR/rootless-cni/{run,var}` will be mounted to `/{run,var}`. To ensure that we keep the netns directory we bind mount this relative to the new root location, e.g. XDG_RUNTIME_DIR/rootless-cni/run/user/1000/netns before we mount the run directory. The run directory is mounted recursive, this makes the netns directory at the same path accessible as before. This also allows iptables-legacy to work because /run/xtables.lock is now writeable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of a fix for an earlier bug (#5698) we added the ability for Podman to chown volumes to correctly match the user running in the container, even in adverse circumstances (where we don't know the right UID/GID until very late in the process). However, we only did this for volumes created automatically by a `podman run` or `podman create`. Volumes made by `podman volume create` do not get this chown, so their permissions may not be correct. I've looked, and I don't think there's a good reason not to do this chwon for all volumes the first time the container is started. I would prefer to do this as part of volume copy-up, but I don't think that's really possible (copy-up happens earlier in the process and we don't have a spec). There is a small chance, as things stand, that a copy-up happens for one container and then a chown for a second, unrelated container, but the odds of this are astronomically small (we'd need a very close race between two starting containers).
