  • f30ab418a   pkt_sched: Remove qdisc->ops->requeue() etc. ... Browse Code »

    After implementing qdisc->ops->peek() and changing sch_netem into
    classless qdisc there are no more qdisc->ops->requeue() users. This
    patch removes this method with its wrappers (qdisc_requeue()), and
    also unused qdisc->requeue structure. There are a few minor fixes of
    warnings (htb_enqueue()) and comments btw.

    The idea to kill ->requeue() and a similar patch were first developed
    by David S. Miller.

  • c27f339af   net_sched: Add qdisc __NET_XMIT_BYPASS flag ... Browse Code »

    Patrick McHardy noticed that it would be nice to
    handle NET_XMIT_BYPASS by NET_XMIT_SUCCESS with an internal qdisc flag
    __NET_XMIT_BYPASS and to remove the mapping from dev_queue_xmit().

    David Miller spotted a serious bug in the first
    version of this patch.

  • 378a2f090   net_sched: Add qdisc __NET_XMIT_STOLEN flag ... Browse Code »

    Patrick McHardy noticed:
    "The other problem that affects all qdiscs supporting actions is
    TC_ACT_QUEUED/TC_ACT_STOLEN getting mapped to NET_XMIT_SUCCESS
    even though the packet is not queued, corrupting upper qdiscs'
    qlen counters."

    and later explained:
    "The reason why it translates it at all seems to be to not increase
    the drops counter. Within a single qdisc this could be avoided by
    other means easily, upper qdiscs would still increase the counter
    when we return anything besides NET_XMIT_SUCCESS though.

    This means we need a new NET_XMIT return value to indicate this to
    the upper qdiscs. So I'd suggest to introduce NET_XMIT_STOLEN,
    return that to upper qdiscs and translate it to NET_XMIT_SUCCESS
    in dev_queue_xmit, similar to NET_XMIT_BYPASS."

    David Miller noticed:
    "Maybe these NET_XMIT_* values being passed around should be a set of
    bits. They could be composed of base meanings, combined with specific
    attributes.

    So you could say "NET_XMIT_DROP | __NET_XMIT_NO_DROP_COUNT"

    The attributes get masked out by the top-level ->enqueue() caller,
    such that the base meanings are the only thing that make their
    way up into the stack. If it's only about communication within the
    qdisc tree, let's simply code it that way."

    This patch is trying to realize these ideas.

  • 5ce2d488f   pkt_sched: Remove 'dev' member of struct Qdisc. ... Browse Code »

    It can be obtained via the netdev_queue. So create a helper routine,
    qdisc_dev(), to make the transformations nicer looking.

    Now, qdisc_alloc() now no longer needs a net_device pointer argument.

  • bb949fbd1   netdev: Create netdev_queue abstraction. ... Browse Code »

    A netdev_queue is an entity managed by a qdisc.

    Currently there is one RX and one TX queue, and a netdev_queue merely
    contains a backpointer to the net_device.

    The Qdisc struct is augmented with a netdev_queue pointer as well.

    Eventually the 'dev' Qdisc member will go away and we will have the
    resulting hierarchy:

    net_device --> netdev_queue --> Qdisc

    Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue
    pointer argument.

    Make nlmsg_trim(), nlmsg_cancel(), genlmsg_cancel(), and

    Return -EMSGSIZE instead of -1 if the provided message buffer is not
    big enough.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
