* container restore/import: store networks from dbPaul Holzinger2021-12-14
| | | | | | | | It is important that we store the current networks from the db in the config. Also make sure to properly handle aliases and ignore static ip/mac addresses. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Add new networks format to spegecenPaul Holzinger2021-12-14
| | | | | | | | Add the new networks format to specgen. For api users cni_networks is still supported to make migration easier however the static ip and mac fields are removed. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* network connect allow ip, ipv6 and mac addressPaul Holzinger2021-12-14
| | | | | | | | | Network connect now supports setting a static ipv4, ipv6 and mac address for the container network. The options are added to the cli and api. Fixes #9883 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* network db: add new strucutre to container createPaul Holzinger2021-12-14
| | | | | | | | | | Make sure we create new containers in the db with the correct structure. Also remove some unneeded code for alias handling. We no longer need this functions. The specgen format has not been changed for now. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* network db rewrite: migrate existing settingsPaul Holzinger2021-12-14
| | | | | | | | | | | | | | The new network db structure stores everything in the networks bucket. Previously some network settings were not written the the network bucket and only stored in the container config. Instead of the old format which used the container ID as value in the networks buckets we now use the PerNetworkoptions struct there. To migrate existing users we use the state.GetNetworks() function. If it fails to read the new format it will automatically migrate the old config format to the new one. This is allows a flawless migration path. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* inotify: make sure to remove filesValentin Rothberg2021-12-09
| | | | | | | | | | | | | | | | Issue #11825 suggests that *rootless* Podman can run into situations where too many inotify fds are open. Indeed, rootless Podman has a slightly higher usage of inotify watchers than the root counterpart when using slirp4netns Make sure to not only close all watchers but to also remove the files from being watched. Otherwise, the fds only get closed when the files are removed. [NO NEW TESTS NEEDED] since we don't have a way to test it. Fixes: #11825 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to follow all symlinks in the /etc/resolv.conf path. Currently we would only check the last file but it is possible that any directory before that is also a link. Unfortunately this code is very hard to maintain and not well tested. I will try to come up with a unit test when I have more time. I think we could utilize some for of chroot for this. For now we are stucked with the default setup in the fedora/ubunutu test VMs. [NO NEW TESTS NEEDED] Fixes #12461 Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rootlessNetNS.Cleanup() has an issue with how it detects if cleanup is needed, reading the container state is not good ebough because containers are first stopped and than cleanup will be called. So at one time two containers could wait for cleanup but the second one will fail because the first one triggered already the cleanup thus making rootless netns unavailable for the second container resulting in an teardown error. Instead of checking the container state we need to check the netns state. Secondly, podman unshare --rootless-netns should not do the cleanup. This causes more issues than it is worth fixing. Users also might want to use this to setup the namespace in a special way. If unshare also cleans this up right away we cannot do this.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem with creating and storing the exit command when the container was created. It only contains the options the container was created with but NOT the options the container is started with. One example would be a CNI network config. If I start a container once, then change the cni config dir with `--cni-config-dir` ans start it a second time it will start successfully. However the exit command still contains the wrong `--cni-config-dir` because it was not updated. To fix this we do not want to store the exit command at all. Instead we create it every time the conmon process for the container is startet. This guarantees us that the container cleanup process is startet with the correct settings.

To fix it we use one netns for each libpod instances. To prevent name conflicts we use a hash from the static dir as part of the name. Previously this worked because we would use the CNI files to check if the netns was still in use. but this is no longer possible with netavark.

There is also a change to make sure we are backwards compatible with old config which include this plugin.
