  • This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

  • Cleanup of dev_base list use, with the aim to simplify making device
    list per-namespace. In almost every occasion, use of dev_base variable
    and dev->next pointer could be easily replaced by for_each_netdev
    loop. A few most complicated places were converted to using
    first_netdev()/next_netdev().

  • Adjust the new netdevice scanning code provided by Patrick McHardy:

    (1) Restore the function banner comments that were dropped.

    (2) Rather than using an array size of 6 in some places and an array size of
    ETH_ALEN in others, pass a pointer instead and pass the array size
    through so that we can actually check it.

    (3) Do the buffer fill count check before checking the for_primary_ifa
    condition again. This permits us to skip that check should maxbufs be
    reached before we run out of interfaces.

  • Replace the large and complicated rtnetlink client by two simple
    functions for getting the MAC address for the first ethernet device
    and building a list of IPv4 addresses.
