Flow lookup can happen either in packet processing context or userspace context but it was annotated as requiring RCU read lock to be held. This also allows OVS mutex to be held without causing warnings.

Over the time datapath.c and flow.c has became pretty large files. Following patch restructures functionality of component into three different components: flow.c: contains flow extract. flow_netlink.c: netlink flow api. flow_table.c: flow table api. This patch restructures code without changing logic. Signed-off-by: NPravin B Shelar <pshelar@nicira.com> Signed-off-by: NJesse Gross <jesse@nicira.com>

Rehashing in ovs-workqueue can cause ovs-mutex lock contentions in case of heavy flow setups where both needs ovs-mutex. So by moving rehashing to flow-setup we can eliminate contention. This also simplify ovs locking and reduces dependence on workqueue. Signed-off-by: NPravin B Shelar <pshelar@nicira.com> Signed-off-by: NJesse Gross <jesse@nicira.com>

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.

Currently OVS uses combination of genl and rtnl lock to protect datapath state. This was done due to networking stack locking. But this has complicated locking and there are few lock ordering issues with new tunneling protocols. Following patch simplifies locking by introducing new ovs mutex and now this lock is used to protect entire ovs state.

Until now, the optional OVS_USERSPACE_ATTR_USERDATA attribute had to be exactly 64 bits long, if it was present. However, 64 bits is not enough space to associate as much information with a flow as would be convenient for some userspace features now under development. This commit generalizes the attribute, allowing it to be any length. This generalization is backward-compatible: if userspace only uses 64-bit attributes, then it will not see any change in behavior.

It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: N"Eric W.

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.

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: NJesse Gross <jesse@nicira.com>
