[ovs-dev] [PATCH v19 5/8] dpif-offload-netlink: Implement dpif-offload-provider API

Implement dpif-offload API for netlink datapath. And implement a dummy dpif-offload API for netdev datapath to make tests pass. Signed-off-by: Chris Mi Reviewed-by: Eli Britstein --- lib/automake.mk | 2 + lib/dpif-netdev.c | 8 +- lib/dpif-netlink.c | 4 +-

[ovs-dev] [PATCH v19 4/8] netdev-offload-tc: Introduce group ID management API

When offloading sample action to TC, userspace creates a unique ID to map sFlow action and tunnel info and passes this ID to kernel instead of the sFlow info. psample will send this ID and sampled packet to userspace. Using the ID, userspace can recover the sFlow info and send sampled packet to

[ovs-dev] [PATCH v19 8/8] system-offloads-traffic.at: Add sFlow offload test cases

Add two sFlow offload test caes: 3: sflow offloads with sampling=1 - ping between two ports - offloads enabled ok 4: sflow offloads with sampling=2 - ping between two ports - offloads enabled ok Signed-off-by: Chris Mi Acked-by: Eelco Chaudron --- tests/system-offloads-traffic.at | 101

[ovs-dev] [PATCH v19 7/8] netdev-offload-tc: Add offload support for sFlow

Create a unique group ID to map the sFlow info when offloading sFlow action to TC. When showing the offloaded datapath flows, translate the group ID from TC sample action to sFlow info using the mapping. Signed-off-by: Chris Mi Reviewed-by: Eli Britstein Acked-by: Eelco Chaudron --- NEWS

[ovs-dev] [PATCH v19 3/8] dpif-offload-provider: Introduce dpif-offload-provider layer

Some offload actions require functionality that is not netdev based, but dpif. For example, sFlow action requires to create a psample netlink socket to receive the sampled packets from TC or kernel driver. Create dpif-offload-provider layer to support such actions. Signed-off-by: Chris Mi

[ovs-dev] [PATCH v19 0/8] Add offload support for sFlow

This patch set adds offload support for sFlow. Psample is a genetlink channel for packet sampling. TC action act_sample uses psample to send sampled packets to userspace. When offloading sample action to TC, userspace creates a unique ID to map sFlow action and tunnel info and passes this ID to

Some sporadic false positive may be visible for the following tests: - conntrack - IPv6 HTTP - conntrack - FTP over IPv6 The failures show up randomly. The reason appears to be source address used when performing the request using wget:

[ovs-dev] [PATCH] conntrack: Check TCP state while testing established connections pick up.

When testing if an established connection is picked up, it could be useful to verify that the protocol state matches the expectation, that is, it moves to ESTABLISHED, as there's a chance that code modifications may break the TCP conn_update() in a way that it returns CT_UPDATE_VALID without
