2013-08-23openvswitch: Mega flow implementationAndy Zhou1-19/+77
Add wildcarded flow support in kernel datapath. Wildcarded flow can improve OVS flow set up performance by avoid sending matching new flows to the user space program. The exact performance boost will largely dependent on wildcarded flow hit rate. In case all new flows hits wildcard flows, the flow set up rate is within 5% of that of linux bridge module. Pravin has made significant contributions to this patch. Including API clean ups and bug fixes.

2013-06-19openvswitch: Add gre tunnel support.Pravin B Shelar1-1/+17
Add gre vport implementation. Most of gre protocol processing is pushed to gre module. It make use of gre demultiplexer therefore it can co-exist with linux device based gre tunnels.

2013-06-19openvswitch: Optimize flow key match for non tunnel flows.Pravin B Shelar1-3/+3
Following patch adds start offset for sw_flow-key, so that we can skip tunneling information in key for non-tunnel flows. Signed-off-by: Pravin B Shelar <[email protected]> Acked-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-06-19openvswitch: Expand action buffer size.Pravin B Shelar1-1/+1
MAX_ACTIONS_BUFSIZE limits action list size, set tunnel action needs extra space on action list, for now increase max actions list limit. Signed-off-by: Pravin B Shelar <[email protected]> Acked-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-06-19openvswitch: Add tunneling interface.Pravin B Shelar1-0/+19
Add ovs tunnel interface for set tunnel action for userspace. Signed-off-by: Pravin B Shelar <[email protected]> Acked-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2013-06-19openvswitch: Copy individual actions.Pravin B Shelar1-1/+1
Rather than validating actions and then copying all actiaons in one block, following patch does same operation in single pass. This validate and copy action one by one. This is required for ovs tunneling patch. This patch does not change any functionality.

2013-03-29openvswitch: Refine Netlink message size calculation and kill FLOW_BUFSIZEThomas Graf1-21/+0
Kills the FLOW_BUFSIZE constant which needs to be calculated manually and replaces it with key_attr_size() based on nla_total_size(). Calculates the size of datapath messages instead of relying on NLMSG_DEFAULT_SIZE and moves the existing message size calculations into own functions for clarity.

2012-09-15Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller1-3/+5
Conflicts: net/netfilter/nfnetlink_log.c net/netfilter/xt_LOG.c Rather easy conflict resolution, the 'net' tree had bug fixes to make sure we checked if a socket is a time-wait one or not and elide the logging code if so. Whereas on the 'net-next' side we are calculating the UID and GID from the creds using different interfaces due to the user namespace changes from Eric Biederman. Signed-off-by: David S.

2012-09-03openvswitch: Increase maximum number of datapath ports.Pravin B Shelar1-1/+2
Use hash table to store ports of datapath. Allow 64K ports per switch. Signed-off-by: Pravin B Shelar <[email protected]> Signed-off-by: Jesse Gross <[email protected]>
2012-09-03openvswitch: Fix FLOW_BUFSIZE definition.Jesse Gross1-3/+5
The vlan encapsulation fields in the maximum flow defintion were never updated when the representation changed before upstreaming. In theory this could cause a kernel panic when a maximum length flow is used. In practice this has never happened (to my knowledge) because skb allocations are padded out to a cache line so you would need the right combination of flow and packet being sent to userspace.

2011-12-03net: Add Open vSwitch kernel components.Jesse Gross1-0/+199
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 <[email protected]>
