* Add rootless support for cni and --uidmapPaul Holzinger2021-04-01
| | | | | | This is supported with the new rootless cni logic. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | Make sure we do not display the expected error when using podman network reload. This is already done for iptables-legacy however iptables-nft creates a slightly different error message so check for this as well. The error is logged at info level. [NO TESTS NEEDED] The test VMs do not use iptables-nft so there is no way to test this. It is already tested for iptables-legacy. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

| * Ensure manually-created volumes have correct ownershipMatthew Heon2021-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Do not leak libpod package into the remote clientPaul Holzinger2021-03-15
| | | | | | | | | | | | | | | | | | Some packages used by the remote client imported the libpod package. This is not wanted because it adds unnecessary bloat to the client and also causes problems with platform specific code(linux only), see #9710. The solution is to move the used functions/variables into extra packages which do not import libpod. This change shrinks the remote client size more than 6MB compared to the current master. [NO TESTS NEEDED] I have no idea how to test this properly but with #9710 the cross compile should fail. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if you attempt to create a kube.yaml file off of a non running container where the container runs as a specific User, the creation fails because the storage container is not mounted. Podman is supposed to read the /etc/passwd entry inside of the container but since the container is not mounted, the c.State.Mountpoint == "". Podman incorrectly attempts to read /etc/passwd on the host, and fails if the specified user is not in the hosts /etc/passwd.

As such, we have to make sure that the deferred c.lock.Unlock() in c.StopWithTimeout() always runs on a locked container. There was a case in c.stop() where we could return an error after we unlock the container to stop it, but before we re-lock it - thus allowing for a double-unlock to occur.
