* add network prunebaude2021-02-06
| | | | | | | | | add the ability to prune unused cni networks. filters are not implemented but included both compat and podman api endpoints. Fixes :#8673 Signed-off-by: baude <bbaude@redhat.com>
* Honor network options for macvlan networksbaude2021-02-02
| | | | | | | | | when creating a macvlan network, we should honor gateway, subnet, and mtu as provided by the user. Fixes: #9167 Signed-off-by: baude <bbaude@redhat.com>
* add macvlan as a supported network driverbaude2021-02-01
| | | | | | | | | | | | instead of using the --macvlan to indicate that you want to make a macvlan network, podman network create now honors the driver name of *macvlan*. Any options to macvlan, like the parent device, should be specified as a -o option. For example, -o parent=eth0. the --macvlan option was marked as deprecated in the man page but is still supported for the duration of 3.0. Signed-off-by: baude <bbaude@redhat.com>
* disable dnsname when --internalbaude2021-01-25
| | | | | | | | when doing a network creation, the dnsname plugin should be disabled when the --internal bool is set. a warning is displayed if this happens and docs are updated. Signed-off-by: baude <bbaude@redhat.com>
* Move the cni lock file into the cni config dirPaul Holzinger2021-01-21
| | | | | | | | | | | | | | Commit(fe3faa517e1b) introduced a lock file for network create/rm calls. There is a problem with the location of the lock file. The lock file was stored in the tmpdir. Running multiple podman network create/remove commands in parallel with different tmpdirs made the lockfile inaccessible to the other process, and so parallel read/write operations to the cni config directory continued to occur. This scenario happened frequently during the e2e tests and caused some flakes. Fixes #9041 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Fix problems reported by staticcheckPaul Holzinger2021-01-12
| | | | | | | | | | | | | | `staticcheck` is a golang code analysis tool. https://staticcheck.io/ This commit fixes a lot of problems found in our code. Common problems are: - unnecessary use of fmt.Sprintf - duplicated imports with different names - unnecessary check that a key exists before a delete call There are still a lot of reported problems in the test files but I have not looked at those.

* Always add the default gateway to the cni config filePaul Holzinger2020-12-16
| | | | | | | | | | | | `podman network create` should always add a gateway to the cni config. If no gateway is given use the first ip in the subnet. CNI does not require the gateway field but we need it because of network inspect. This worked with previous version but was dropped in Commit(e7a72d72fd59). Fixes #8748 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Add support for network idsPaul Holzinger2020-12-02
| | | | | | | | | | | | | | | | | | | The network ID is not stored. It is just the sha256 hash from the network name. There is a risk of a potential hash collision. However it's very unlikely and even if we hit this it will complain that more than network with this ID exists. The main benefit is that the compat api can have proper network ID support. Also this adds the support for `podman network ls --format "{{.ID}}"` and `--filter id=<ID>`. It also ensures that we can do network rm <ID> and network inspect <ID>. Since we use a hash this commit is backwards compatible even for already existing networks. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

Use the `args` field in the cni config file to store the podman labels. Use `podman_labels` as key name and store the labels as map[string]string. For reference: https://github.com/containernetworking/cni/blob/master/CONVENTIONS.md#args-in-network-config https://github.com/containernetworking/cni/blob/spec-v0.4.0/SPEC.md#network-configuration Example snippet: ``` ... "args": { "podman_labels": { "key1":"value1", "key2":"value2" } } ... ``` Make podman network list support several filters. Supported filters are name, plugin, driver and label. Filters with different keys work exclusive. Several label filters work exclusive and the other filter keys are working inclusive. Also adjust the compat api to support labels in network create and list. Breaking changes: - podman network ls -f shortform is used for --filter instead --format This matches docker and other podman commands (container ps, volume ps) - libpod network list endpoint filter parameter is removed. Instead the filters paramter should be used as json encoded map[string][]string. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* | Fix problems with network removePaul Holzinger2020-11-26
|/ | | | | | | | | First, make sure we are only trying to remove the network interface if we are root. Second, if we cannot get the interface name (e.g macvlan config) then we should not fail. Just remove the config file. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Fix custom mac address with a custom cni networkPaul Holzinger2020-11-24
| | | | | | | | | | | The cni plugin `tuning` is required to set a custom mac address. This plugin is configured in the default cni config file which is packaged with podman but was not included the generated config form `podman network create`.

* Fix ip-range for classless subnet masksPaul Holzinger2020-11-23
| | | | | | | | | | | The `LastIPInSubnet` function worked only for classful subnet masks (e.g. /8, /16, /24). For non standard subnet masks this returned the wrong ip address. This works now for all subnet mask. A unit test is added to ensure this. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* add network connect|disconnect compat endpointsbaude2020-11-17
| | | | | | | | | | | this enables the ability to connect and disconnect a container from a given network. it is only for the compatibility layer. some code had to be refactored to avoid circular imports. additionally, tests are being deferred temporarily due to some incompatibility/bug in either docker-py or our stack.

* prevent unpredictable results with network create|removebaude2020-10-07
due to a lack of "locking" on cni operations, we could get ourselves in trouble when doing rapid creation or removal of networks. added a simple file lock to deal with the collision and because it is not considered a performent path, use of the file lock should be ok. if proven otherwise in the future, some generic shared memory lock should be implemented for libpod and also used here. moved pkog/network to libpod/network because libpod is now being pulled into the package and it has therefore lost its generic nature. this will make it easier to absorb into libpod as we try to make the network closer to core operations.
