* podman stats: calc CPU percentage correctlyPaul Holzinger2022-03-22
| | | | | | | | | | | | | | | | | | | | | When you run podman stats, the first interval always shows the wrong cpu usage. To calculate cpu percentage we get the cpu time from the cgroup and compare this against the system time between two stats. Since the first time we do not have a previous stats an empty struct is used instead. Thus we do not use the actual running time of the container but the current unix timestamp (time since Jan 1 1970). To fix this we make sure that the previous stats time is set to the container start time, when it is empty. [NO NEW TESTS NEEDED] No idea how I could create a test which would have a predictable cpu usage. See the linked bugzilla for a reproducer.

* | podman machine: remove hostip from portPaul Holzinger2022-03-17
|/ | | | | | | | | | | | | | | | Inside the podman machine vm we always remove the hostip from the port mapping because this should only be used on the actual host. Otherwise you run into issues when we would bind 127.0.0.1 or try to bind a host address that is not available in the VM. This was already done for cni/netavark ports and slirp4netns but not for the port bindings inside libpod which are only used as root. [NO NEW TESTS NEEDED] We still do not have machine tests!

* slirp: fix setup on ipv6 disabled systemsPaul Holzinger2022-03-14
| | | | | | | | | | | | | | | | | When enable_ipv6=true is set for slirp4netns (default since podman v4), we will try to set the accept sysctl. This sysctl will not exist on systems that have ipv6 disabled. In this case we should not error and just ignore the extra ipv6 setup. Also the current logic to wait for the slirp4 setup was kinda broken, it did not actually wait until the sysctl was set before starting slirp. This should now be fixed by using two `sync.WaitGroup`s.

* | container: workdir resolution must consider symlink if explicitly configuredAditya R2022-03-02
|/ | | | | | | | | | | | | | | | | | | | | | | While resolving `workdir` we mostly create a `workdir` when `stat` fails with `ENOENT` or `ErrNotExist` however following cases are not true when user explicitly specifies a `workdir` while `running` using `--workdir` which tells `podman` to only use workdir if its exists on the container. Following configuration is implicity set with other `run` mechanism like `podman play kube` Problem with explicit `--workdir` or similar implicit config in `podman play kube` is that currently podman ignores the fact that workdir can also be a `symlink` and actual `link` could be valid. Hence following commit ensures that in such scenarios when a `workdir` is not found and we cannot create a `workdir` podman must perform a check to ensure that if `workdir` is a `symlink` and `link` is resolved successfully and resolved link is present on the container then we return as it is. Docker performs a similar behviour. Signed-off-by: Aditya R <arajan@redhat.com>

* | Remove the runtime lockMatthew Heon2022-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This primarily served to protect us against shutting down the Libpod runtime while operations (like creating a container) were happening. However, it was very inconsistently implemented (a lot of our longer-lived functions, like pulling images, just didn't implement it at all...) and I'm not sure how much we really care about this very-specific error case? Removing it also removes a lot of potential deadlocks, which is nice. [NO NEW TESTS NEEDED] Signed-off-by: Matthew Heon <mheon@redhat.com>

* | Propagate $CONTAINERS_CONF to conmonDavid Gibson2022-02-18
|/ | | | | | | | | | | | | | | | | | | | | The CONTAINERS_CONF environment variable can be used to override the configuration file, which is useful for testing. However, at the moment this variable is not propagated to conmon. That means in particular, that conmon can't propagate it back to podman when invoking its --exit-command. The mismatch in configuration between the starting and cleaning up podman instances can cause a variety of errors. This patch also adds two related test cases. One checks explicitly that the correct CONTAINERS_CONF value appears in conmon's environment. The other checks for a possible specific impact of this bug: if we use a nonstandard name for the runtime (even if its path is just a regular crun), then the podman container cleanup invoked at container exit will fail. That has the effect of meaning that a container started with -d --rm won't be correctly removed once complete. Fixes #12917 Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

* Modify /etc/resolv.conf when connecting/disconnectingMatthew Heon2022-02-10
| | | | | | | | | | | | | | | | | | The `podman network connect` and `podman network disconnect` commands give containers access to different networks than the ones they were created with; these networks can also have DNS servers associated with them. Until now, however, we did not modify resolv.conf as network membership changed. With this PR, `podman network connect` will add any new nameservers supported by the new network to the container's /etc/resolv.conf, and `podman network disconnect` command will do the opposite, removing the network's nameservers from `/etc/resolv.conf`.

| | | | | | | | | | | | | | | | | | | | | | | | | | When running podman inside systemd user units, it is possible that systemd kills the rootless netns slirp4netns process because it was started in the default unit cgroup. When the unit is stopped all processes in that cgroup are killed. Since the slirp4netns process is run once for all containers it should not be killed. To make sure systemd will not kill the process we move it to the user.slice. Fixes #13153 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

When we want to users to migrate to the new network stack we recommend to run podman system reset. However this did not remove networks and if there were still networks around we would continue to use cni since this was considered an old system. There is one exception for the default network. It should not be removed since this could cause other issues when it no longer exists. The network backend detection logic ignores the default network so this is fine.
