[ovs-dev] [PATCH ovn] Fix conntrack entry leaks because of TCP RST packets not sent to conntrack.

From: Numan Siddique The commit [1] - 28097d5adb95("Fix tcp_reset action handling") fixed an issue with tcp_reset OVN action. In order to fix that issue, this commit added logical flows to skip all the TCP RST packets from conntrack. Ideally it should have skipped only the TCP RST packets generat

[ovs-dev] [RFC PATCH 3/4] dpif-netdev: Skip encap action during datapath execution

In this patch we check if action processing (apart from OUTPUT action), should be skipped for a given dp_netdev_flow. Specifically, we check if the action is TNL_PUSH and if it has been offloaded to HW, then we do not push the tunnel header in SW. The datapath only executes the OUTPUT action. The p

[ovs-dev] [RFC PATCH 0/4] RFC for Partial action offload

Hi, This RFC patchset extends the "Partial HW acceleration" mode to offload part of the action processing to HW, instead of offloading just lookup (MARK/RSS), for "vhost-user" ports. This is referred to as "Partial Action Offload". This mode does not require SRIOV/switchdev configuration. In this

[ovs-dev] [RFC PATCH 1/4] dpif-netdev: Refactor dp_netdev_flow_offload_put()

This patch refactors dp_netdev_flow_offload_put() to prepare for more changes to support partial action offload, in subsequent patches. - Add a wrapper function to allocate flow-mark. - Move netdev_ports_get() to before flow-mark allocation. Signed-off-by: Sriharsha Basavapatna --- lib/dpif-net

[ovs-dev] [RFC PATCH 2/4] dpif-netdev: Support partial-action-offload of VXLAN encap flow

In this patch, we support offloading of VXLAN_ENCAP action for a vhost-user port (aka "partial-action-offload"). At the time of offloading the flow, we determine if the flow can be offloaded to an egress device, if the input port is not offload capable such as a vhost-user port. We then offload the

For flows that offload partial actions in egress direction, provide the right netdev to fetch statistics. Signed-off-by: Sriharsha Basavapatna --- lib/dpif-netdev.c | 10 -- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/lib/dpif-netdev.c b/lib/dpif-netdev.c index 7fcc0b06

[ovs-dev] [PATCH ovn v2] Add SCTP load balancer test.

This is essentially a copy of existing load balancer tests that use TCP, but with a few modifications for SCTP. Userspace conntrack and SCTP do not currently mix. Therefore, the test has been added to a new kernel-only system testsuite file. If userspace conntrack support for SCTP is added in the
