datapath: Turn vports with dependencies into separate modules Upstream commit: The internal and netdev vport remain part of openvswitch.ko. Encap vports including vxlan, gre, and geneve can be built as separate modules and are loaded on demand. Modules can be unloaded after use. Datapath ports keep a reference to the vport module during their lifetime. Allows to remove the error prone maintenance of the global list vport_ops_list. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net> Also folds in the follow-up commits 9ba559d9ca3 to turned the non-GPL symbol exports to GPL exports, and fa2d8ff4e35 which fixes a module reference release bug. Exports various backwards compat functions linked into the main openvswitch module as GPL symbols to ensure vport modules can use them. Some fiddling with the Makefile was needed to work around the fact that Makefile variables can't contain '-' characters needed to define 'vport-xxx' module sources. Also, Kbuild complains heavily if a $(module)-y = $(module).o is defined which is actually backed with a .c file of the same name. Therefore, a new $(build_multi_modules) variable is defined which lists all module which consist of more than one source file.

datapath: Add Stateless TCP Tunneling protocol. The Stateless TCP Tunnel (STT) protocol encapsulates traffic in IPv4/TCP packets. STT uses TCP segmentation offload available in most of NIC. On packet xmit STT driver appends STT header along with TCP header to the packet. For GSO packet GSO parameters are set according to tunnel configuration and packet is handed over to networking stack. This allows use of segmentation offload available in NICs The protocol is documented at http://www.ietf.org/archive/id/draft-davie-stt-06.txt Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: Jesse Gross <jesse@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com>

datapath: Add conntrack action Expose the kernel connection tracker via OVS. Userspace components can make use of the CT action to populate the connection state (ct_state) field for a flow. This state can be subsequently matched. Exposed connection states are OVS_CS_F_*: - NEW (0x01) - Beginning of a new connection. - ESTABLISHED (0x02) - Part of an existing connection. - RELATED (0x04) - Related to an established connection. - INVALID (0x20) - Could not track the connection for this packet. - REPLY_DIR (0x40) - This packet is in the reply direction for the flow. - TRACKED (0x80) - This packet has been sent through conntrack. When the CT action is executed by itself, it will send the packet through the connection tracker and populate the ct_state field with one or more of the connection state flags above. The CT action will always set the TRACKED bit. When the COMMIT flag is passed to the conntrack action, this specifies that information about the connection should be stored. This allows subsequent packets for the same (or related) connections to be correlated with this connection. Sending subsequent packets for the connection through conntrack allows the connection tracker to consider the packets as ESTABLISHED, RELATED, and/or REPLY_DIR. The CT action may optionally take a zone to track the flow within. This allows connections with the same 5-tuple to be kept logically separate from connections in other zones. If the zone is specified, then the "ct_zone" match field will be subsequently populated with the zone id. IP fragments are handled by transparently assembling them as part of the CT action. The maximum received unit (MRU) size is tracked so that refragmentation can occur during output. IP frag handling contributed by Andy Zhou. Based on original design by Justin Pettit.

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.

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: 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.

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.

datapath: Add support for lwtunnel Following patch adds support for lwtunnel to OVS datapath. With this change OVS datapath detect lwtunnel support and make use of new APIs if available. On older kernel where the support is not there the backported tunnel modules are used. These backported tunnel devices acts as lwtunnel devices. I tried to keep backported module same as upstream for easier bug-fix backport. Since STT and LISP are not upstream OVS always needs to use respective modules from tunnel compat layer. To make it work on kernel 4.3 I have converted STT and LISP modules to lwtunnel API model. lwtunnel make use of skb-dst to pass tunnel information to the tunnel module. On older kernel this is not possible. So the in case of old kernel metadata ref is stored in OVS_CB and direct call to tunnel transmit function is made by respective tunnel vport modules. Similarly on receive side tunnel recv directly call netdev-vport-receive to pass the skb to OVS. Major backported components include: Geneve, GRE, VXLAN, ip_tunnel, udp-tunnels GRO.
