      bonding: alternate agg selection policies for 802.3ad · fd989c83
      Jay Vosburgh 提交于
      	This patch implements alternative aggregator selection policies
      for 802.3ad.  The existing policy, now termed "stable," selects the active
      aggregator by greatest bandwidth, and only reselects a new aggregator
      if the active aggregator is entirely disabled (no more ports or all ports
      down).
      
      	This patch adds two new policies: bandwidth and count, selecting
      the active aggregator by total bandwidth (like the stable policy) or by
      the number of ports in the aggregator, respectively.  These two policies
      also differ from the stable policy in that they will reselect the active
      aggregator when availability-related changes occur in the bond (e.g.,
      link state change).
      
      	This permits "gang failover" within 802.3ad, allowing redundant
      aggregators along parallel paths to always maintain the "best" aggregator
      as the active aggregator (rather than having to wait for the active to
      entirely fail).
      
      	This patch also updates the driver version to 3.5.0.

      bonding: Fix ALB mode to balance traffic on VLANs · 6146b1a4
      Jay Vosburgh 提交于
      	The current ALB function that processes incoming ARPs
      does not handle traffic for VLANs configured above bonding.  This causes
      traffic on those VLANs to all be assigned the same slave.  This patch
      corrects that misbehavior by locating the bonding interface nested below
      the VLAN interface.
      
      	Bug reported by Sven Anders <anders@anduras.de>, who also
      tested an earlier version of this patch and confirmed that it resolved
      the problem.

      bonding: send IPv6 neighbor advertisement on failover · 305d552a
      Brian Haley 提交于
      This patch adds better IPv6 failover support for bonding devices,
      especially when in active-backup mode and there are only IPv6 addresses
      configured, as reported by Alex Sidorenko.
      
      - Creates a new file, net/drivers/bonding/bond_ipv6.c, for the
         IPv6-specific routines.  Both regular bonds and VLANs over bonds
         are supported.
      
      - Adds a new tunable, num_unsol_na, to limit the number of unsolicited
         IPv6 Neighbor Advertisements that are sent on a failover event.
         Default is 1.
      
      - Creates two new IPv6 neighbor discovery functions:
      
         ndisc_build_skb()
         ndisc_send_skb()
      
         These were required to support VLANs since we have to be able to
         add the VLAN id to the skb since ndisc_send_na() and friends
         shouldn't be asked to do this.  These two routines are basically
         __ndisc_send() split into two pieces, in a slightly different order.
      
      - Updates Documentation/networking/bonding.txt and bumps the rev of bond
         support to 3.4.0.
      
      On failover, this new code will generate one packet:
      
      - An unsolicited IPv6 Neighbor Advertisement, which helps the switch
         learn that the address has moved to the new slave.
      
      Testing has shown that sending just the NA results in pretty good
      behavior when in active-back mode, I saw no lost ping packets for example.

      net: Guaranetee the proper ordering of the loopback device. · ae33bc40
      Eric W. Biederman 提交于
      I was recently hunting a bug that occurred in network namespace
      cleanup.  In looking at the code it became apparrent that we have
      and will continue to have cases where if we have anything going
      on in a network namespace there will be assumptions that the
      loopback device is present.   Things like sending igmp unsubscribe
      messages when we bring down network devices invokes the routing
      code which assumes that at least the loopback driver is present.
      
      Therefore to avoid magic initcall ordering hackery that is hard
      to follow and hard to get right insert a call to register the
      loopback device directly from net_dev_init().    This guarantes
      that the loopback device is the first device registered and
      the last network device to go away.
