openvswitch: Validation of IPv6 set port action uses IPv4 header 2012-05-08T00:23:10+00:00 Pravin B Shelar pshelar@nicira.com 2012-05-08T00:21:53+00:00 072ae6314a191e3a9fc309b1e4e539ac7abc48ad When the kernel validates set TCP/UDP port actions, it looks at the ports in the existing flow to make sure that the L4 header exists. However, these actions always use the IPv4 version of the struct. Following patch fixes this by checking for flow ip protocol first.

openvswitch: Honor dp_ifindex, when specified, for vport lookup by name. 2012-03-06T23:04:04+00:00 Ben Pfaff blp@nicira.com 2012-03-06T23:04:04+00:00 651a68ea2ce9738b84e928836053b2e0fb5db2ba When OVS_VPORT_ATTR_NAME is specified and dp_ifindex is nonzero, the logical behavior would be for the vport name lookup scope to be limited to the specified datapath, but in fact the dp_ifindex value was ignored.

net: Add Open vSwitch kernel components. 2011-12-03T17:35:17+00:00 Jesse Gross jesse@nicira.com 2011-10-26T02:26:31+00:00 ccb1352e76cff0524e7ccb2074826a092dd13016 Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules.
