* Instead of erroring, clean up after dangling IDs in DBMatthew Heon2022-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For various (mostly legacy) reasons, Podman presently maintains a unified namespace for pods and containers - IE, we cannot have both a pod and a container named "test" at the same time. To implement this, we use a global database table of every pod and container ID (and another of every pod and container name). These entries should be added when containers/pods are added, and removed when containers/pods are removed, with the database's transactional integrity providing a guarantee that this is batched with the overall removal and that the DB should remain sane and consistent no matter what. As such, we treat a dangling ID as a hard error that stops the use of Podman. Unfortunately, we have someone run into this last Friday. I'm still not certain how exactly their DB got into this state, but without further clarification there, we can consider removing the error and making Podman instead clean up and remove any dangling IDs, which should restore Podman to a serviceable state. Drop an error message if we do this, though, because people should know that the DB is in a bad state. [NO NEW TESTS NEEDED] it is deliberately impossible to produce a configuration that would test this without hex-editing the DB file. Signed-off-by: Matthew Heon <mheon@redhat.com>

* Make errors on removing exec sessions nonfatalMatthew Heon2022-06-14
| | | | | | | | | | | | | | | | | Removing exec sessions is guaranteed to evict them from the DB, but in the case of a zombie process (or similar) it may error and block removal of the container. A subsequent run of `podman rm` would succeed (because the exec sessions have been purged from the DB), which is potentially confusing to users. So let's just continue, instead of erroring out, if removing exec sessions fails. [NO NEW TESTS NEEDED] I wouldn't want to spawn a zombie in our test VMs even if I could.

* Don't complain about XDG_RUNTIME_DIR, Closes #1424Kevin Downey2022-06-14
| | | | | | | | | | | | | | Code is not directly reading XDG_RUNTIME_DIR, it is reading a value in the state that may initially be from XDG_RUNTIME_DIR, but then is overriden by a value from the boltdb that podman stores some state in. XDG_RUNTIME_DIR and the RunRoot path may not have the same value, so complaining about XDG_RUNTIME_DIR here may cause confusion when trying to debug things.

* libpod: unset networks before storing container confPaul Holzinger2022-05-03
| | | | | | | | | | | | Since networks must always be read from the db bucket directly we should unset them in config to avoid caller from accidentally using them. I already tried this but it didn't work because the networks were unset after the config was marshalled. [NO NEW TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* libpod: host netns keep same /etc/resolv.confPaul Holzinger2022-05-03
| | | | | | | | | | | | When a container is run in the host network namespace we have to keep the same resolv.conf content and not use the systemd-resolve detection logic. But also make sure we still allow --dns options. Fixes #14055 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| | | | | | | | | | | | | | The files /etc/hosts, /etc/hostname and /etc/resolv.conf should always be owned by the root user in the container. This worked correct for /etc/hostname and /etc/hosts but not for /etc/resolv.conf. A container run with --userns keep-id would have the reolv.conf file owned by the current container user which is wrong.

* volume: add new option -o o=noquotaGiuseppe Scrivano2022-05-03
| | | | | | | | | | | | | | | | | add a new option to completely disable xfs quota usage for a volume. xfs quota set on a volume, even just for tracking disk usage, can cause weird errors if the volume is later re-used by a container with a different quota projid. More specifically, link(2) and rename(2) might fail with EXDEV if the source file has a projid that is different from the parent directory. To prevent such kind of issues, the volume should be created beforehand with `podman volume create -o o=noquota $ID` Closes: https://github.com/containers/podman/issues/14049 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* | enable gocritic linterPaul Holzinger2022-04-26
|/ | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image <image>` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.
