  • This is a trivial patch against the hdlcdrv module that fixes its CRC
    calculation. The finished CRC was overwriting the first two bytes of
    each packet rather than being appended to the end.

    I've tested this with 2.6.8 and 2.6.10-rc1, but hdlcdrv hasn't changed
    much recently so it should work with many other kernel versions.

  • Move the line disciplines towards a conventional ->ops arrangement. For
    the moment the actual 'tty_ldisc' struct in the tty is kept as part of
    the tty struct but this can then be changed if it turns out that when it
    all settles down we want to refcount ldiscs separately to the tty.

    Pull the ldisc code out of /proc and put it with our ldisc code.

  • alloc_netdev_mq() now allocates an array of netdev_queue
    structures for TX, based upon the queue_count argument.

    Furthermore, all accesses to the TX queues are now vectored
    through the netdev_get_tx_queue() and netdev_for_each_tx_queue()
    interfaces. This makes it easy to grep the tree for all
    things that want to get to a TX queue of a net device.

    Problem spots which are not really multiqueue aware yet, and
    only work with one queue, can easily be spotted by grepping
    for all netdev_get_tx_queue() calls that pass in a zero index.

  • Add netif_addr_{lock,unlock}{,_bh}() helpers.

    Use them to protect operations that operate on or read
    the network device unicast and multicast address lists.

    Also use them in cases where the code simply wants to
    block calls into the driver's ->set_rx_mode() and
    ->set_multicast_list() methods.

  • If the RTNL is held when we invoke flush_scheduled_work() we could
    deadlock. One such case is linkwatch, it is a work struct which tries
    to grab the RTNL semaphore.

    The most common case are net driver ->stop() methods. The
    simplest conversion is to instead use cancel_{delayed_}work_sync()
    explicitly on the various work struct the driver uses.

    This is an OK transformation because these work structs are doing
    things like resetting the chip, restarting link negotiation, and so
    forth. And if we're bringing down the device, we're about to turn the
    chip off and reset it anways. So if we cancel a pending work event,
    that's fine here.

    Some drivers were working around this deadlock by using a msleep()
    polling loop of some sort, and those cases are converted to instead
    use cancel_{delayed_}work_sync() as well.

  • According to one of OOPSes reported by Jann softirq can break
    while skb is prepared for netif_rx. The report isn't complete,
    so the real reason of the later bug could be different, but
    IMHO this locking break in ax_bump is unsafe and unnecessary.

  • Every user of the network device notifiers is either a protocol
    stack or a pseudo device. If a protocol stack that does not have
    support for multiple network namespaces receives an event for a
    device that is not in the initial network namespace it quite possibly
    can get confused and do the wrong thing.

    To avoid problems until all of the protocol stacks are converted
    this patch modifies all netdev event handlers to ignore events on
    devices that are not in the initial network namespace.

    As the rest of the code is made network namespace aware these
    checks can be removed.

  • This patch modifies every packet receive function
    registered with dev_add_pack() to drop packets if they
    are not from the initial network namespace.

    This should ensure that the various network stacks do
    not receive packets in a anything but the initial network
    namespace until the code has been converted and is ready
    for them.

  • This patch makes /proc/net per network namespace. It modifies the global
    variables proc_net and proc_net_stat to be per network namespace.
    The proc_net file helpers are modified to take a network namespace argument,
    and all of their callers are fixed to pass &init_net for that argument.
    This ensures that all of the /proc/net files are only visible and
    usable in the initial network namespace until the code behind them
    has been updated to be handle multiple network namespaces.

    Making /proc/net per namespace is necessary as at least some files
    in /proc/net depend upon the set of network devices which is per
    network namespace, and even more files in /proc/net have contents
    that are relevant to a single network namespace.

  • The rcu_dereference() primitive needs to be applied to an l-value in order to
    ensure that compiler writers don't get an opportunity to apply reordering
    optimizations that could result in multiple fetches or in other misbehavior.
    This patch pulls the rcu_dereference() calls in bpq_seq_next() up to the point
    at which the fetched pointers are still l-values, rather than after
    list_entry() has transformed them into r-values.
