openvswitch: Move LRO check from transmit to receive.

2013-01-22T07:57:26Z

The check for LRO packets was incorrectly put in the transmit path instead of on receive. Since this check is supposed to protect OVS (and other parts of the system) from packets that it cannot handle it is obviously not useful on egress. Therefore, this commit moves it back to the receive side. The primary problem that this caused is upcalls to userspace tried to segment the packet even though no segmentation information is available. This would later cause NULL pointer dereferences when skb_gso_segment() did nothing. Signed-off-by: Jesse Gross

openvswitch: Use RCU callback when detaching netdevices.

2012-11-28T22:04:34Z

Currently, each time a device is detached from an OVS datapath we call synchronize RCU before freeing associated data structures. However, if a bridge is deleted (which detaches all ports) when many devices are connected then there can be a long delay. This switches to use call_rcu() to group the cost together.

openvswitch: Print device when warning about over MTU packets.

2012-10-30T22:48:48Z

If an attempt is made to transmit a packet that is over the device's MTU then we log it using the datapath's name. However, it is much more helpful to use the device name instead. Signed-off-by: Jesse Gross

openvswitch: Add support for network namespaces.

2012-08-22T21:48:55Z

Following patch adds support for network namespace to openvswitch. Since it must release devices when namespaces are destroyed, a side effect of this patch is that the module no longer keeps a refcount but instead cleans up any state when it is unloaded.

net: Add Open vSwitch kernel components.

2011-12-03T17:35:17Z

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. See http://openvswitch.org for more information and userspace utilities. Signed-off-by: Jesse Gross
