[PATCH 1/3] lnst.Tests.TestPMD: adapt to two executable names
by olichtne＠redhat.com 29 Jun '21

29 Jun '21

From: Ondrej Lichtner <olichtne(a)redhat.com> Added a property that returns the name of the base testpmd executable. At some point in the dpdk upstream development the name of the binary changed to "dpdk-testpmd", breaking the use of this TestModule on rhel8. This also adds an additional "sanity check" by testing to see if the executable is actually installed with "is_installed" and raising an exception in case it isn't.

[PATCH 00/13] Additional namespace fixes
by Jan Tluka 24 Jun '21

24 Jun '21

This patch set fixes several problems with the movement of devices between namespaces. All devices are set to readonly cache mode on machine cleanup. This resolves an issue when the RecipeRun results are inspected after it has completed. For example when printing the DeviceCreateResult description a query is sent to the LNST agents and a soft device may not exist anymore which raises an exception. A new dictionary of devices moved between namespaces is added to Machine object that serves as a temporary cache of the devices for the time when they are removed from a namespace and appear in the new namespace. This resolves an issue with previous implementation when a duplicate RemoteDevice was created in the Machine's device database. With the new implementation the initial instance of the device is used. A fix of the peer and peer_name properties of VethDevice is included. These properties need to be implemented on the controller side in the RemoteDevice class because of missing facility to get the peer device on an LNST agent. Finally, the IFLA_NEW_IFINDEX attribute is included in the notification message since the ifindex of the moved device may change if there's already a device with the same index in the namespace. Jan Tluka (13): Slave.NetTestSlave: fix set_dev_netns RemoteDevice: return immediately from enable_readonly_cache if already cached Controller.Machine: add methods to set device readonly cache Controller.Machine: set cacheonly mode for all devices on a machine cleanup Machine: remove commented out code Device: handle unsupported features exceptions Devices.VethDevice: peer property fixes Controller.Machine: add _find_device_in_any_namespace Devices.RemoteDevice: add peer property Devices.RemoteDevice: add peer_name property Slave.InterfaceManager: include IFLA_NEW_IFINDEX when a device is moved to a net namespace Controller.Machine: add cache for devices moved to a namespace Controller.Machine: handle device namespace movement lnst/Controller/Machine.py | 88 +++++++++++++++++++++++++++++++--- lnst/Devices/Device.py | 27 +++++++++-- lnst/Devices/RemoteDevice.py | 15 ++++++ lnst/Devices/VethDevice.py | 27 +++++------ lnst/Slave/InterfaceManager.py | 1 + lnst/Slave/NetTestSlave.py | 2 - 6 files changed, 132 insertions(+), 28 deletions(-) -- 2.26.3

[ANNOUNCEMENT] update to README.md wrt contacts and contributions
by Ondrej Lichtner 16 Jun '21

16 Jun '21

Hi all, just a small announcement: * due to the freenode situation I have removed the info about the #lnst channel on freenode and I will not be joining it anymore. As the channel wasn't really active anyway I have not created a replacement channel anywhere either. As such if you want to contact us, please do so over github issues or via this mailing list. * at the same time I decided to try out accepting pull requests and issues for contributions. For now I still want to keep the commit history linear so any reviews I'll do will mention this and I'll enforce it. But this may change in the future. * I also added a link to the read the docs documentation page. It's not "complete" but should be somewhat useful already. Thanks, -Ondrej

[PATCH 00/43] Netns fixes and tunnel recipes
by Jan Tluka 11 Jun '21

11 Jun '21

This is an aggregation of my previous patch series: * Recipes.ENRT: add L2TPTunnelRecipe to ENRT module imports * Device.GeneveDevice: add external property * Various tunnel recipes * Tunnel recipes enhancements There was a major issue with loopback device and also multiple issues with how the devices were handled in namespaces which is fixed now by additional patches. The original series that were merged here are identical, only the new patches should be reviewed. Additional patches fixes several bugs with the namespaces. In particular: * Machine's device_database is now namespace aware * loopback device is handled separately while initializing InterfaceManager * Machine's device_delete method is now namespace aware * added special handler for RTM_DELLINK event on device net namespace changes Summary of the original series cover letters follows. Series: Various tunnel recipes This patch series extends the ENRT test recipe set with additional tunnel recipes. The series also includes updates to VxlanDevice and a bug fix for Device class required by VxlanGpeTunnelRecipe. Series: Tunnel recipes enhancements 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. Jan Tluka (43): Recipes.ENRT: add L2TPTunnelRecipe to ENRT module imports Recipes.ENRT: add Ip6GreNetnsTunnelRecipe.py Device.GeneveDevice: add external property Devices.GreDevice: add external property Devices.VxlanDevice: add external property Devices: add LoopbackDevice Machine: remove unused get_configuration method NetTestSlave: include netns when forwarding a from_netns message Controller.MessageDispatcher: pass netns argument to device_created method Slave.InterfaceManager: use LoopbackDevice for loopback devices Controller.Machine: change _namespaces to dictionary Controller.Machine: make device_database namespace aware Controller.Machine: handle loopback devices in device_create() call Controller.Namespace: handle LoopbackDevice assignment Controller.Namespace: update device's _id in device_database in special cases Controller.Machine: make device_delete netns-aware Controller.MessageDispatcher: pass netns in device_delete call Controller/Slave: handle RTM_DELLINK on net namespace changes Recipes.ENRT.ConfigMixins: enable usage of individual HWConfigMixins Recipes.ENRT: add GeneveLwtTunnelRecipe Recipes.ENRT: add GreLwtTunnelRecipe Recipes.ENRT: add VxlanLwtTunnelRecipe Recipes.ENRT: add GreOvsTunnelRecipe Recipes.ENRT: add GeneveOvsTunnelRecipe Recipes.ENRT: add VxlanOvsTunnelRecipe Recipes.ENRT: add

Devices.Device: handle RTM_NEWLINK messages without any IFLA_ADDRESS Recipes.ENRT: add VxlanGpeTunnelRecipe Recipes.ENRT.L2TPTunnelRecipe: add carrier_ipversion parameter Recipes.ENRT.L2TPTunnelRecipe: load l2tp_eth module before creating the tunnel Recipes.ENRT.L2TPTunnelRecipe: add PauseFramesHWConfigMixin Recipes.ENRT.GeneveTunnelRecipe: add OffloadSubConfigMixin
