[PATCH] NetConfigDeviceVxlan: Allow to specify extra ip flags for vxlan device

by Roi Dayan

This is sometimes and the flags cannot be changed after the device is created. for example we need to allow zero ipv6 checksum when working with OVS vxlan interface against native vxlan interface. We need to set udp6zerocsumrx udp6zerocsumtx.

[PATCH LNST 00/11] L2 MC tests

by Nogah Frankel

This patchset adds some basic test for L2 MC behaviours. The first three patches add a MC related commands to LNST. The 4th patch adds the ability to count CPU traffic, so it will be possible to check if the traffic were really offloaded and hadn't gone via slowpath. Patches 5 & 6 update the current MDB test to be more generic and to check that the traffic is offloaded. Patch 7 adds a test to check that the MDB is ignored when MC is disabled. Patches 8-10 add tests for mrouter bridge config option (as in IGMP configuration, not to be confused with any L3 property). Patch 11 adds a test for unregistered MC packets. This patchset does not address: * LAG in MC. * static MDB, Nogah Frankel (11): common: add a consts file for mrouter port related consts Interface: add mcast flood and mrouter set functions Bridge: add set mcast bridge functions Interface: Add cpu ifstat function recipes: switchdev: TestLib: Change iperf_mc to be more generic recipes: switchdev: TestLib: Check whether packets goes in slowpath recipes: switchdev: Add the mdb mcast disabled test recipes: switchdev: Add basic mrouter test recipes: switchdev: Add mrouter learning test recipes: switchdev: Add a test for many floods with mrouters recipes: switchdev: Add a test for unregistered MC traffic lnst/Common/Consts.py | 16 +++ lnst/Controller/Machine.py | 20 +++ lnst/Controller/Task.py | 15 +++ lnst/Slave/BridgeTool.py | 10 ++ lnst/Slave/InterfaceManager.py | 42 ++++++ lnst/Slave/NetTestSlave.py | 43 +++++++ recipes/switchdev/TestLib.py | 94 +++++++------- recipes/switchdev/l2-020-bridge_mdb.py | 38 ++++-- .../switchdev/l2-022-bridge_mdb_mcast_disabled.py | 85 ++++++++++++ .../switchdev/l2-022-bridge_mdb_mcast_disabled.xml | 70 ++++++++++ .../l2-023-bridge_mdb_mc_router_port_basic.py | 108 ++++++++++++++++ .../l2-023-bridge_mdb_mc_router_port_basic.xml | 70 ++++++++++ .../l2-024-bridge_mdb_mc_router_port_learning.py | 91 +++++++++++++ .../l2-024-bridge_mdb_mc_router_port_learning.xml | 70 ++++++++++ .../l2-025-bridge_mdb_flood_with_mc_router.py | 142 +++++++++++++++++++++ .../l2-025-bridge_mdb_flood_with_mc_router.xml | 70 ++++++++++ recipes/switchdev/l2-026-bridge_mdb_unreg_flood.py | 92 +++++++++++++ .../switchdev/l2-026-bridge_mdb_unreg_flood.xml | 70 ++++++++++ 18 files changed, 1093 insertions(+), 53 deletions(-) create mode 100644 lnst/Common/Consts.py create mode 100644 recipes/switchdev/l2-022-bridge_mdb_mcast_disabled.py create mode 100644 recipes/switchdev/l2-022-bridge_mdb_mcast_disabled.xml create mode 100644 recipes/switchdev/l2-023-bridge_mdb_mc_router_port_basic.py create mode 100644 recipes/switchdev/l2-023-bridge_mdb_mc_router_port_basic.xml create mode 100644 recipes/switchdev/l2-024-bridge_mdb_mc_router_port_learning.py create mode 100644 recipes/switchdev/l2-024-bridge_mdb_mc_router_port_learning.xml create mode 100644 recipes/switchdev/l2-025-bridge_mdb_flood_with_mc_router.py create mode 100644 recipes/switchdev/l2-025-bridge_mdb_flood_with_mc_router.xml create mode 100644 recipes/switchdev/l2-026-bridge_mdb_unreg_flood.py create mode 100644 recipes/switchdev/l2-026-bridge_mdb_unreg_flood.xml -- 2.4.3

[PATCH] IRQ: parse msi_irqs directory if /proc/interrupts does not contain device name

by Jan Tluka

For some NICs, e.g. Mellanox ones, the /proc/interrupts file does not contain device name that we use to identify NIC IRQs. Based on Mellanox script get_irq_list I added parsing of msi_irqs under /sys/class/net directory if the former method returned empty list.

next branch updated

by Ondrej Lichtner

Hello everyone, I just pushed all my local changes to the next branch. This includes updates to the Device API that we've discussed and some other minor stuff. At this point it should be possible to start porting some basic recipes. Keep in mind that this will include some additional work in porting old test modules to equivalent test classes - such as IcmpPing or Netperf. As this is our first attempt at porting recipes, one of it's purposes is to also test out the new Device API to see if any changes need to be made, so be prepared for bugs or for things not working exactly as you'd like. Feel free to post any bugfix of feature patches to the mailing list, I'll be watching and reviewing. For anything more complicated I've created a 'next' label in the github issue tracker [1] where you can report bugs. -Ondrej [1] https://github.com/jpirko/lnst/labels/next
