* use libnetwork from c/commonPaul Holzinger2022-01-12
| | | | | | | | The libpod/network packages were moved to c/common so that buildah can use it as well. To prevent duplication use it in podman as well and remove it from here. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* rename libpod nettypes fieldsPaul Holzinger2021-11-16
| | | | | | | | | | Some field names are confusing. Change them so that they make more sense to the reader. Since these fields are only in the main branch we can safely rename them without worrying about backwards compatibility. Note we have to change the field names in netavark too.

* Make networking code reusablePaul Holzinger2021-11-11
| | | | | | | | | | To prevent code duplication when creating new network backends move reusable code into a separate internal package. This allows all network backends to use the same code as long as they implement the new NetUtil interface. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* MAC address json unmarshal should allow stringsPaul Holzinger2021-11-03
| | | | | | | | | Create a new mac address type which supports json marshal/unmarshal from and to string. This change is backwards compatible with the previous versions as the unmarshal method still accepts the old byte array or base64 encoded string. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Document to not set K8S envars for CNIPaul Holzinger2021-10-26
| | | | | | | Setting these environment variables can cause issues with custom CNI plugins, see #12083. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* move network alias validation to container createPaul Holzinger2021-09-28
| | | | | | | | | | Podman 4.0 currently errors when you use network aliases for a network which has dns disabled. Because the error happens on network setup this can cause regression for old working containers. The network backend should not validate this. Instead podman should check this at container create time and also for network connect. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* standardize logrus messages to upper caseDaniel J Walsh2021-09-22
| | | | | | | | Remove ERROR: Error stutter from logrus messages also. [ NO TESTS NEEDED] This is just code cleanup. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Bump CNI to v1.0.1Paul Holzinger2021-09-22
| | | | | | | | | | | | | | | | | | | | | Update CNI so we can match wrapped errors. This should silence ENOENT warnings when trying to read the cni conflist files. Fixes #10926 Because CNI v1.0.0 contains breaking changes we have to change some import paths. Also we cannot update the CNI version used for the conflist files created by `podman network create` because this would require at least containernetwork-plugins v1.0.1 and a updated dnsname plugin. Because this will take a while until it lands in most distros we should not use this version. So keep using v0.4.0 for now. The update from checkpoint-restore/checkpointctl is also required to make sure it no longer uses CNI to read the network status. [NO TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Wire network interface into libpodPaul Holzinger2021-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make use of the new network interface in libpod. This commit contains several breaking changes: - podman network create only outputs the new network name and not file path. - podman network ls shows the network driver instead of the cni version and plugins. - podman network inspect outputs the new network struct and not the cni conflist. - The bindings and libpod api endpoints have been changed to use the new network structure. The container network status is stored in a new field in the state. The status should be received with the new `c.getNetworkStatus`. This will migrate the old status to the new format. Therefore old containers should contine to work correctly in all cases even when network connect/ disconnect is used. New features: - podman network reload keeps the ip and mac for more than one network. - podman container restore keeps the ip and mac for more than one network. - The network create compat endpoint can now use more than one ipam config. The man pages and the swagger doc are updated to reflect the latest changes. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Network interfacePaul Holzinger2021-08-24
Implement a new network interface to abstract CNI from libpod. The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.
