openvswitch:: link upper device for port devices

2013-08-23T23:38:00+00:00

Link upper device properly. That will make IFLA_MASTER filled up.
Set the master to port 0 of the datapath under which the port belongs.

openvswitch: Remove unneeded ovs_netdev_get_ifindex()

2013-04-30T04:19:11+00:00

The only user is get_dpifindex(), no need to redirect via the port
operations.

openvswitch: Simplify datapath locking.

2013-04-15T21:38:40+00:00

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.

openvswitch: Move LRO check from transmit to receive.

2013-01-22T07:57:26+00:00

The check for LRO packets was incorrectly put in the transmit path
instead of on receive.  Since this check is supposed to protect OVS
(and other parts of the system) from packets that it cannot handle
it is obviously not useful on egress.  Therefore, this commit moves
it back to the receive side.

The primary problem that this caused is upcalls to userspace tried
to segment the packet even though no segmentation information is
available.  This would later cause NULL pointer dereferences when
skb_gso_segment() did nothing.

openvswitch: Use RCU callback when detaching netdevices.

2012-11-28T22:04:34+00:00

Currently, each time a device is detached from an OVS datapath
we call synchronize RCU before freeing associated data structures.
However, if a bridge is deleted (which detaches all ports) when
many devices are connected then there can be a long delay.  This
switches to use call_rcu() to group the cost together.

openvswitch: Print device when warning about over MTU packets.

2012-10-30T22:48:48+00:00

If an attempt is made to transmit a packet that is over the device's
MTU then we log it using the datapath's name.  However, it is much
more helpful to use the device name instead.
