Bug#697357: bridging broken over bond interfaces

[Peter Palfrader <weasel@debian.org>]

Package: linux-image-3.2.0-4-amd64
Version: 3.2.35-2
Severity: important

Hi,

I tried to set up a new KVM host in the usual way:
  - have a bond0 interface over all physcial eth* interfaces
  - create a br0 over that bond0 and any vnet* interfaces for the
    guests.

on wheezy's 3.2.0-4-amd64 this setup results in network breaking in the
following way:
  - host can talk to guest and vice versa,
  - host can talk to other hosts on the network, and vice versa,
  - other hosts on the network can get arp replies from guests,
    but cannot talk IP to them.
    tcpdumping on the host suggests the br0 never even sees the packets
    intended for the guest.

*   Manually switching the eth* to promiscious mode makes stuff work.

Cheers,
weasel
