configure: add configure option to disable building brcompat This adds ability to do: ./configure --disable-brcompat to disable building userspace and kernel module associated with providing linux bridge compatibility. Sources should still be distributed w/ make dist. While there, update comment referring to long removed veth driver which is now relevant for brcompat module.

datapath: Consolidate checksum compatibility code. Checksum offloading has changed quite a bit across different kernel and Xen versions. Since it is part of the skb data structure it is unfortunately difficult to separate out into compatibility code. This consolidates all of the checksum code in one place which makes it easier read and remove as we prepare for upstreaming. On newer kernels it also puts everything in inline functions, eliminating the need to run through the compat code or make extra function calls.

datapath: Add vlan acceleration field for older kernels. Kernels prior to 2.6.27 did not have a vlan_tci field in struct sk_buff for vlan acceleration. It's very convenient to use this field for manipulating vlan tags, so we would like to use it as the primary mechanism. To enable this, this commit adds similar infrastructure to the OVS_CB on the kernels that need it and a set of functions to use the correct location.

vlan.c \
datapath: Add generic virtual port layer. Currently the datapath directly accesses devices through their Linux functions. Obviously this doesn't work for virtual devices that are not backed by an actual Linux device. This creates a new virtual port layer which handles all interaction with devices. The existing support for Linux devices was then implemented on top of this layer as two device types. It splits out and renames dp_dev to internal_dev. There were several places where datapath devices had to handled in a special manner and this cleans that up by putting all the special casing in a single location.

vport.c \
datapath: Add support for CAPWAP UDP transport. Add support for the transport portion of the CAPWAP protocol as an alternative to GRE for L2 over L3 tunneling. This is not full support for the CAPWAP protocol. CAPWAP covers management of wireless access points and describes a control protocol for setting those devices up. It also describes a data plane protocol that allows packets to be tunneled to a controller for inspection. This data plane protocol is the only component covered by this commit.

vport: Extract common functions for virtual devices. Pull some generic implementations of vport functions out of the GRE vport so they can be used by others. Also move the code to set the MTUs of internal devices to the minimum of attached devices to the generic vport_set_mtu layer.

vport-generic.c \
tunneling: Add datapath GRE support. Add a new vport type that implements GRE support inside of the datapath instead of relying on Linux devices. This provides greater scalability, performance, and control. The new GRE implementation supports nearly all features of the Linux implementation. It does not currently support multicast, NBMA tunnels, or non-Ethernet devices. This implementation of GRE has several important benefits over the existing Linux implementation. The first is simply that is not a Linux device. Linux devices are fairly heavy weight both in terms of memory consumption and interactions with the rest of the system (notifications, processes polling, etc.). There are many pieces of code that make assumptions about the maximum reasonable number of ports. Simply maintaining the state of several thousand devices is enough to full occupy the CPU. A tighter coupling between the GRE implementation and datapath also allows more flexibility. The key can be set and retrieved from the flow table, which allows even greater scalability. There will probably be additional use cases in the future.

checksum.h \
datapath: Use compat directory only for backported code. Most necessary compatibility code is simply backported versions of kernel functions from newer kernels. These belong in the compat directory, where they can be transparently picked up when necessary. However, in some situations there is code that is different depending on the kernel version but is always needed in some form. Here it is desirable to segregate the code but it does not really belong in the compat directory because it does not exist in upstream kernels. This moves those functions to a compat file, which makes the meaning clear and prevents problems when Open vSwitch is integrated into other projects.

datapath: Describe policy for extending flow key, implement needed changes. When the datapath was converted to use Netlink attributes for describing flow keys, I had a vague idea of how it could be smoothly extensible, but I didn't actually implement extensibility or carefully think it through. This commit adds a document that describes how flow keys can be extended in a compatible fashion and adapts the existing interface to match what it says. This commit doesn't actually implement extensibility. I already have a separate patch series out for that. This patch series borrows from that one heavily, but the extensibility series will need to be reworked somewhat once this one is in. This commit is only lightly tested because I don't have a good test setup for VLANs. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com>
