[PATCH] Device.GeneveDevice: add external property
by Jan Tluka 31 May '21

31 May '21

This is to support so called lightweight tunnels when tunnel metadata is defined externally, e.g. using 'ip route .. encap' command. Since the external flag makes any mandatory options irrelevant, the mandatory options are defined dynamically.

[PATCH 00/11] Tunnel recipes enhancements
by Jan Tluka 27 May '21

27 May '21

This includes several enhancements for the recently added tunnel recipes. The L2TPTunnelRecipe is updated to automatically load the l2tp_eth kernel module that is required by the L2TPTunnelManager to function properly. A new parameter carrier_ipversion is added to this recipe. Rest of the patches adds specific HWConfigMixins to the recipes, to allow mtu, pause frames and offload settings configuration.

[PATCH-legacy-py3] lnst/Slave/NetConfigDevice: don't fail on restoring autoneg settings
by Jan Tluka 26 May '21

26 May '21

The command to restore the autoneg settings returns non-zero exit code after update from RHEL-8.3.0 to RHEL-8.4.0. This causes crash of the recipe on cleanup. To fix this, the die_on_err=False is used to ignore the exit code value.

[PATCH] Controller.Machine: fix moving a device to a network namespace
by Jan Tluka 17 May '21

17 May '21

When a device is moved to a network namespace an RTM_NEWLINK netlink message is generated and handled by InterfaceManager. The InterfaceManager creates a new instance of a generic Device class instead of a specific device class (e.g. VethDevice). This device also remains in disabled state so no actions or configurations can be made. This patch fixes that by following changes. The InterfaceManager is extended with remap_device() method that creates a new instance of the specific device class that replaces the generic Device instance. The SlaveMethods are extended with remap_device() method that serves as an rpc interface for calling InterfaceManager's method from the Controller. The Machine.remote_device_set_netns() method is updated to include an explicit rpc_call to remap the device to proper type.
