* Ensure that 'rmi --force' evicts Podman containersMatthew Heon2020-07-30
| | | | | | | | | | | | | | | | | | | | | The logic for `podman rmi --force` includes a bit of code that will remove Libpod containers using Libpod's container removal logic - this ensures that they're cleanly and completely removed. For other containers (Buildah, CRI-O, etc) we fall back to manually removing the containers using the image from c/storage. Unfortunately, our logic for invoking the Podman removal function had an error, and it did not properly handle cases where we were force-removing an image with >1 name. Force-removing such images by ID guarantees their removal, not just an untag of a single name; our code for identifying whether to remove containers did not proper detect this case, so we fell through and deleted the Podman containers as storage containers, leaving traces of them in the Libpod DB.

| * Make changes to /etc/passwd on disk for non-read onlyMatthew Heon2020-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bind-mounting /etc/passwd into the container is problematic becuase of how system utilities like `useradd` work. They want to make a copy and then rename to try to prevent breakage; this is, unfortunately, impossible when the file they want to rename is a bind mount. The current behavior is fine for read-only containers, though, because we expect useradd to fail in those cases. Instead of bind-mounting, we can edit /etc/passwd in the container's rootfs. This is kind of gross, because the change will show up in `podman diff` and similar tools, and will be included in images made by `podman commit`. However, it's a lot better than breaking important system tools. Fixes #6953 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | Add podman image mountDaniel J Walsh2020-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | There are many use cases where you want to just mount an image without creating a container on it. For example you might want to just examine the content in an image after you pull it for security analysys. Or you might want to just use the executables on the image without running it in a container. The image is mounted readonly since we do not want people changing images.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was added with an earlier exec rework, and honestly is very confusing. Podman is printing an error message, but the error had nothing to do with Podman; it was the executable we ran inside the container that errored, and per `podman run` convention we should set the Podman exit code to the process's exit code and print no error.

Values of the filters map might be empty, so we need to account for that instead of uncondtitionally accessing the first item. Also apply a similar for race conditions as done in commit f4a2d25c0fca: Fix a race that could cause read errors to be masked. Masking such errors is likely to report red herrings since users don't see that reading failed for some reasons but that a given event could not be found. Another race was the handler closing event channel, which could lead to two kinds of panics: double close, send to close channel. The backend takes care of that. However, make sure that the backend stops working in case the context has been cancelled. Fixes: #6899 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of podman 1.8.0, because of commit da7595a, the default approach of providing port-forwarding in rootless mode has switched (and been hard-coded) to rootlessport, for the purpose of providing super performance. The side-effect of this switch is source within the container to the port-forwarded service always appears to originate from 127.0.0.1 (see issue #5138). This commit allows a user to specify if they want to revert to the previous approach of leveraging slirp4netns add_hostfwd() api which, although not as stellar performance, restores usefulness of seeing incoming traffic origin IP addresses. The change should be transparent; when not specified, rootlessport will continue to be used, however if specifying --net slirp4netns:slirplisten the old approach will be used. Note: the above may imply the restored port-forwarding via slirp4netns is not as performant as the new rootlessport approach, however the figures shared in the original commit that introduced rootlessport are as follows: slirp4netns: 8.3 Gbps, RootlessKit: 27.3 Gbps, which are more than sufficient for many use cases where the origin of traffic is more important than limits that cannot be reached due to bottlenecks elsewhere.

* | Preserve passwd on container restartMatthew Heon2020-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added code to create a `/etc/passwd` file that we bind-mount into the container in some cases (most notably, `--userns=keep-id` containers). This, unfortunately, was not persistent, so user-added users would be dropped on container restart. Changing where we store the file should fix this. Further, we want to ensure that lookups of users in the container use the right /etc/passwd if we replaced it. There was already logic to do this, but it only worked for user-added mounts; it's easy enough to alter it to use our mounts as well. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Fix container and pod create commands for remote createMatthew Heon2020-07-10
| | | | | | | | | | | | | | | | | | | | | | | In `podman inspect` output for containers and pods, we include the command that was used to create the container. This is also used by `podman generate systemd --new` to generate unit files. With remote podman, the generated create commands were incorrect since we sourced directly from os.Args on the server side, which was guaranteed to be `podman system service` (or some variant thereof). The solution is to pass the command along in the Specgen or PodSpecgen, where we can source it from the client's os.Args. This will still be VERY iffy for mixed local/remote use (doing a `podman --remote run ...` on a remote client then a `podman generate systemd --new` on the server on the same container will not work, because the `--remote` flag will slip in) but at the very least the output of `podman inspect` will be correct. We can look into properly handling `--remote` (parsing it out would be a little iffy) in a future PR. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Remove all instances of named return "err" from LibpodMatthew Heon2020-07-09
| | | | | | | | | | | | | | | | | This was inspired by https://github.com/cri-o/cri-o/pull/3934 and much of the logic for it is contained there. However, in brief, a named return called "err" can cause lots of code confusion and encourages using the wrong err variable in defer statements, which can make them work incorrectly. Using a separate name which is not used elsewhere makes it very clear what the defer should be doing. As part of this, remove a large number of named returns that were not used anywhere. Most of them were once needed, but are no longer necessary after previous refactors (but were accidentally retained). Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Implement --sdnotify cmdline option to control sd-notify behaviorJoseph Gooch2020-07-06
| | | | | | | | | | | | | | | | | | | --sdnotify container|conmon|ignore With "conmon", we send the MAINPID, and clear the NOTIFY_SOCKET so the OCI runtime doesn't pass it into the container. We also advertise "ready" when the OCI runtime finishes to advertise the service as ready. With "container", we send the MAINPID, and leave the NOTIFY_SOCKET so the OCI runtime passes it into the container for initialization, and let the container advertise further metadata. This is the default, which is closest to the behavior podman has done in the past. The "ignore" option removes NOTIFY_SOCKET from the environment, so neither podman nor any child processes will talk to systemd. This removes the need for hardcoded CID and PID files in the command line, and the PIDFile directive, as the pid is advertised directly through sd-notify.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The infra/abi code for pods was written in a flawed way, assuming that the map[string]error containing individual container errors was only set when the global error for the pod function was nil; that is not accurate, and we are actually *guaranteed* to set the global error when any individual container errors. Thus, we'd never actually include individual container errors, because the infra code assumed that err being set meant everything failed and no container operations were attempted. We were originally setting the cause of the error to something nonsensical ("container already exists"), so I made a new error indicating that some containers in the pod failed. We can then ignore that error when building the report on the pod operation and actually return errors from individual containers. Unfortunately, this exposed another weakness of the infra code, which was discarding the container IDs. Errors from individual containers are not guaranteed to identify which container they came from, hence the use of map[string]error in the Pod API functions. Rather than restructuring the structs we return from pkg/infra, I just wrapped the returned errors with a message including the ID of the container. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
