openvswitch: Fix net exit.

2015-02-20T20:32:08+00:00

Open vSwitch allows moving internal vport to different namespace while still connected to the bridge. But when namespace deleted OVS does not detach these vports, that results in dangling pointer to netdevice which causes kernel panic as follows. This issue is fixed by detaching all ovs ports from the deleted namespace at net-exit. BUG: unable to handle kernel NULL pointer dereference at 0000000000000028 IP: [] ovs_vport_locate+0x35/0x80 [openvswitch] Oops: 0000 [#1] SMP Call Trace: [] lookup_vport+0x21/0xd0 [openvswitch] [] ovs_vport_cmd_get+0x59/0xf0 [openvswitch] [] genl_family_rcv_msg+0x1bc/0x3e0 [] genl_rcv_msg+0x79/0xc0 [] netlink_rcv_skb+0xb9/0xe0 [] genl_rcv+0x2c/0x40 [] netlink_unicast+0x12d/0x1c0 [] netlink_sendmsg+0x34a/0x6b0 [] sock_sendmsg+0xa0/0xe0 [] ___sys_sendmsg+0x408/0x420 [] __sys_sendmsg+0x51/0x90 [] SyS_sendmsg+0x12/0x20 [] system_call_fastpath+0x12/0x17 Reported-by: Assaf Muller Fixes: 46df7b81454("openvswitch: Add support for network namespaces.")

openvswitch: Introduce ovs_tunnel_route_lookup

2015-01-14T21:32:06+00:00

Introduce ovs_tunnel_route_lookup to consolidate route lookup shared by vxlan, gre, and geneve ports. Signed-off-by: Fan Du Signed-off-by: David S. Miller

openvswitch: Extend packet attribute for egress tunnel info

2014-11-10T02:58:44+00:00

OVS vswitch has extended IPFIX exporter to export tunnel headers to improve network visibility. To export this information userspace needs to know egress tunnel for given packet. By extending packet attributes datapath can export egress tunnel info for given packet. So that userspace can ask for egress tunnel info in userspace action. This information is used to build IPFIX data for given flow. Signed-off-by: Wenyu Zhang Acked-by: Romain Lenglet Acked-by: Ben Pfaff Signed-off-by: Pravin B Shelar

ovs: Turn vports with dependencies into separate modules

2014-10-28T18:43:18+00:00

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.

openvswitch: Add support for Geneve tunneling.

2014-10-06T04:32:21+00:00

The Openvswitch implementation is completely agnostic to the options that are in use and can handle newly defined options without further work. It does this by simply matching on a byte array of options and allowing userspace to setup flows on this array.

openvswitch: Wrap struct ovs_key_ipv4_tunnel in a new structure.

2014-10-06T04:32:20+00:00

Currently, the flow information that is matched for tunnels and the tunnel data passed around with packets is the same. However, as additional information is added this is not necessarily desirable, as in the case of pointers. This adds a new structure for tunnel metadata which currently contains only the existing struct. This change is purely internal to the kernel since the current OVS_KEY_ATTR_IPV4_TUNNEL is simply a compressed version of OVS_KEY_ATTR_TUNNEL that is translated at flow setup.

openvswitch: change the data type of error status to atomic_long_t

2014-09-09T18:48:07+00:00

Change the date type of error status from u64 to atomic_long_t, and use atomic operation, then remove the lock which is used to protect the error status. The operation of atomic maybe faster than spin lock. Cc: Pravin Shelar Signed-off-by: Li RongQing Signed-off-by: David S. Miller

openvswitch: Allow each vport to have an array of 'port_id's.

2014-07-24T08:15:04+00:00

In order to allow handlers directly read upcalls from datapath, we need to support per-handler netlink socket for each vport in datapath. This commit makes this happen. Also, it is guaranteed to be backward compatible with previous branch. Signed-off-by: Alex Wang Acked-by: Thomas Graf Signed-off-by: Pravin B Shelar
