bonding: fix ad_select module param check

2014-07-14T21:36:58+00:00

Obvious copy/paste error when I converted the ad_select to the new
option API. "lacp_rate" there should be "ad_select" so we can get the
proper value.

bonding: Advertize vxlan offload features when supported

2014-06-18T23:49:51+00:00

When the underlying device supports TCP offloads for VXLAN/UDP
encapulated traffic, we need to reflect that through the hw_enc_features
field of the bonding net-device. This will cause the xmit path
in the core networking stack to provide bonding with encapsulated
GSO frames to offload into the HW etc.

bonding: Support macvlans on top of tlb/rlb mode bonds

2014-06-04T22:13:54+00:00

To make TLB mode work, the patch allows learning packets
to be sent using mac addresses assigned to macvlan devices,
also taking into an account vlans that may be between the
bond and macvlan device.

To make RLB work, all we have to do is accept ARP packets
for addresses added to the bond dev->uc list.  Since RLB
mode will take care to update the peers directly with
correct mac addresses, learning packets for these addresses
do not have be send to switch.

bonding: Turn on IFF_UNICAST_FLT on bond devices

2014-06-04T22:13:54+00:00

Bonding devices manage the unicast filters of the underlying
interfaces, but do not turn on IFF_UNICAST_FLT flag.  Thus
anytime a unicast address is added to the bond, the bond is
places in promiscuous mode.

Turn on IFF_UNICAST_FLT on the bond device so that the bond does
not go into promiscuous mode needlesly.  If an underlying device
does not support unicast filtering, that device will automaticall
enter promiscuous mode already.

Several cases of overlapping changes.

The xfrm6_output.c has a bug fix which overlaps the renaming
of skb->local_df to skb->ignore_df.

In the Altera TSE driver cases, the register access cleanups
in net-next overlapped with bug fixes done in net.

Similarly a bug fix to send ALB packets in the bonding driver using
the right source address overlaps with cleanups in net-next.

bonding: Send ALB learning packets using the right source

2014-05-22T19:47:58+00:00

ALB learning packets are currentlyalways sent using the slave mac
address for all vlans configured on top of bond.   This is not always
correct, as vlans may change their mac address.
This patch introduced a concept of strict matching where the
source of learning packets can either strictly match the address
passed in, or it can determine a more correct address to use.

There are 3 casese to consider:
  1) Switchover.  In this case, we have a new active slave and we need
     tell the switch about all addresses available on the slave.
  2) Monitor.  We'll periodically refresh learning info for all slaves.
     In this case, we refresh all addresses for current active, and just
     the slave address for other slaves.
  3) Teaching of disabled adddress.  This happens as part of the
     failover and in this case, we alwyas to use just the address
     provided.

bonding: remove NULL verification from bond_get_bond_by_slave()

2014-05-22T19:46:34+00:00

Every caller relies on the result being the actual bond, so this
verification just masks the real problem.

bonding: populate essential new_slave->bond/dev early

2014-05-22T19:46:34+00:00

The new bond_free_slave() needs new_slave->bond to verify if additional
structures were allocated, so populate it early so that, in case of failure
in bond_enslave(), we would be able to get it.

Also populate the new_slave->dev field, as it's too one of the most needed
things to assign early.

bonding: Don't assume 802.1Q when sending alb learning packets.

2014-05-22T19:44:58+00:00

TLB/ALB learning packets always assume 802.1Q vlan protocol, but
that is no longer the case since we now have support for Q-in-Q
on top of bonding.  Pass the vlan protocol to alb_send_lp_vid()
so that the packets are properly tagged.

bonding: fix vlan_features computing

2014-05-22T19:07:23+00:00

bond_compute_features() uses netdev_increment_features() to
combine vlan_features of slaves into vlan_features of the bond.
As netdev_increment_features() only adds most features and we
start with BOND_VLAN_FEATURES, we can end up with features none
of the slaves provided.

If there is at least one slave, initialize vlan_features only
with the flags in NETIF_F_ALL_FOR_ALL. Right now there is none
in BOND_VLAN_FEATURES but stating it explicitely will make the
code more future proof.
