* specgen: improve heuristic for /sys bind mountGiuseppe Scrivano2021-01-15
| | | | | | | | | | | | | partially revert 95c45773d7dbca2880152de681c81f0a2afec99b restrict the cases where /sys is bind mounted from the host. The heuristic doesn't detect all the cases where the bind mount is not necessary, but it is an improvement on the previous version where /sys was always bind mounted for rootless containers unless --net none was specified.

| | | | | | | | | | | | | | | | | | | | | | | | We can't mount sysfs as rootless unless we manage the network namespace. Problem: slirp4netns is now creating and managing a network namespace separate from the OCI runtime, so we can't mount sysfs in many circumstances. The `crun` OCI runtime will automatically handle this by falling back to a bind mount, but `runc` will not, so we didn't notice until RHEL gating tests ran on the new branch.

* / Do not use "true" after "syslog" in exit commandsMatthew Heon2020-12-01
|/ | | | | | | | | | | | | | | | | | | | | Instead of being interpreted as an argument to the boolean flag, the 'true' is being intepreted as the Podman command to be run - so we're trying to run `podman true`, which does not exist. This causes the cleanup command to fail when `--log-level=debug` is set, so containers are not cleaned up or removed. This problem is easily reproduced with any command combining the `--rm`, `-d`, and `--log-level=debug` flags - the command will execute and exit, but the container will not be removed. Separate, but worth looking into later: the errors we get on trying `podman true` with any flags are terrible - if you just type `podman true` you get a quite sane "Unrecognized command" error, but if you try `podman true --rm` you get an "unknown flag --rm" error - which makes very little sense given the command itself doesn't exist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In k8s a persistent volume claim (PVC) allow pods to define a volume by referencing the name of a PVC. The PVC basically contains criterias that k8s then use to select which storage source it will use for the volume. Podman only provide one abtracted storage, the named volumes, and create them if they don't exists yet. So this patch simply use a volume with the name of the PVC.

This now fails later and only on the server and not the client. I don't think I can add a test for this because the CI runs server and client always on the same vm.
