* datapath: lisp: Fix uninitialized field in tunnel_cfg.Yunjian Wang2018-09-121-0/+1
| | | | | | | | | The tunnel_cfg had the gro_receive and gro_complete fields uninitialized in function lisp_open(). This caused an uninitialized memory read. Signed-off-by: Yunjian Wang <wangyunjian@huawei.com> Signed-off-by: Ben Pfaff <blp@ovn.org> Reviewed-by: Greg Rose <gvrose8192@gmail.com>

* datapath: compat: Fix build on RHEL 7.5Yi-Hung Wei2018-05-141-0/+4
| | | | | | | | | | | | | | | | | | 1) OVS datapath compat modules breaks on RHEL 7.5, because it moves ndo_change_mtu function pointer from 'struct net_device_ops' to 'struct net_device_ops_extended'. 2) RHEL 7.5 introduces the MTU range checking as mentioned in 6c0bf091 ("datapath: use core MTU range checking in core net infra"). However, the max_mtu field is defined in 'struct net_device_extended' but not in 'struct net_device' as upstream kernel. This patch defines a new symbol HAVE_RHEL7_MAX_MTU that determines the previous 2 conditions, and fixes the backport issue.

* datapath: Fixup RTNL ops for kernel 4.13Greg Rose2017-09-221-11/+10
| | | | | | | | | | | | | The RTNL ops validate and newlink functions now take the extended netlink ack parameter. Use the new HAVE_EXT_ACK_IN_RTNL_LINKOPS define to check if the additional parameter is present and add the parameter if so. While in the modules remove the checks for Linux kernels < 2.3.39 since they are no longer supported since 2.5.x.

* compat: Implement upstream net device free change.Greg Rose2017-07-241-0/+4
| | | | | | | | | | | | Upstream commit cf124db566e6 ("net: Fix inconsistent teardown and release of private netdev state.") removed the destructor member of the net_device structure and replaced it with a boolean flag indicating that the net device resource needs freeing. Use compat flag HAVE_NEEDS_FREE_NETDEV to indicate whether the new flag should be used. Signed-off-by: Greg Rose <gvrose8192@gmail.com> Signed-off-by: Joe Stringer <joe@ovn.org>
* lisp: avoid using stale lisp socket.Pravin B Shelar2016-10-311-9/+25
| | | | | | | | | | | This patch is similar to earlier vxlan patch. Lisp device close operation frees lisp socket. This operation can race with lisp-xmit function which dereferences lisp socket. Following patch uses RCU mechanism to avoid this situation. Signed-off-by: Pravin B Shelar <pshelar@ovn.org> Acked-by: Joe Stringer <joe@ovn.org>

| | | | | | | | | | | | | upstream tunnel egress info is retrieved using ndo_fill_metadata_dst. Since we do not have it on older kernel we need to keep vport operation to do same on these kernels.

* datapath: Drop support for kernel older than 3.10Pravin B Shelar2016-03-141-7/+3
| | | | | | | | | | | | | | | | Currently OVS out of tree datapath supports a large number of kernel versions. From 2.6.32 to 4.3 and various distribution-specific kernels. But at this point major features are only available on more recent kernels. For example, stateful services are only available starting in kernel 3.10 and STT is available on starting with 3.5. Since these features are becoming essential to many OVS deployments, and the effort of maintaining the backports is high. We have decided to drop support for older kernel. Following patch drops supports for kernel older than 3.10. Signed-off-by: Pravin B Shelar <pshelar@ovn.org> Acked-by: Jesse Gross <jesse@kernel.org>
* datapath: lisp: Relax MTU constraints.Joe Stringer2016-02-191-1/+15
| | | | | | | | | | Currently, even if the entire path supports jumbo frames, the LISP netdev limits the path MTU to 1500 bytes, and cannot be configured otherwise. Relax the constraints on modifying the device MTU, and set it to the maximum by default. Signed-off-by: Joe Stringer <joe@ovn.org> Acked-by: Jesse Gross <jesse@kernel.org>
* datapath: Add support for lwtunnelPravin B Shelar2015-12-031-0/+711
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.
