* Drop dependency on iproutePaul Holzinger2021-09-02
| | | | | | | | | | | We only use the `ip` util to remove a network interface. We can do this directly via the netlink lib, no need to call a external binary. [NO TESTS NEEDED] Fixes #11403 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* dual-stack network: fix duplicated subnet assignmentPaul Holzinger2021-07-26
| | | | | | | | | Make sure podman network create reads all subnets from existing cni configs and not only the first one. Fixes #11032 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Split libpod/network packagePaul Holzinger2021-03-15
| | | | | | | | | | | | The `libpod/network` package should only be used on the backend and not the client. The client used this package only for two functions so move them into a new `pkg/network` package. This is needed so we can put linux only code into `libpod/network`, see #9710.

* Fix podman network IDs handlingPaul Holzinger2021-02-22
| | | | | | | | | | | | | The libpod network logic knows about networks IDs but OCICNI does not. We cannot pass the network ID to OCICNI. Instead we need to make sure we only use network names internally. This is also important for libpod since we also only store the network names in the state. If we would add a ID there the same networks could accidentally be added twice. Fixes #9451 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* bump go module to v3Valentin Rothberg2021-02-22
| | | | | | | | | We missed bumping the go module, so let's do it now :) * Automated go code with github.com/sirkon/go-imports-rename * Manually via `vgrep podman/v2` the rest Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* 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>
* 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>
* 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>
* 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>
* 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>
* 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.
