  • 52d58aef5   llc: replace the socket list with a local address based hash ... Browse Code »

    For the cases where a lot of interfaces are used in conjunction with a
    lot of LLC sockets bound to the same SAP, the iteration of the socket
    list becomes prohibitively expensive.

    Replacing the list with a a local address based hash significantly
    improves the bind and listener lookup operations as well as the
    datagram delivery.

    Connected sockets delivery is also improved, but this patch does not
    address the case where we have lots of sockets with the same local
    address connected to different remote addresses.

    In order to keep the socket sanity checks alive and fast a socket
    counter was added to the SAP structure.

  • 6d2e3ea28   llc: use a device based hash table to speed up multicast delivery ... Browse Code »

    This patch adds a per SAP device based hash table to solve the
    multicast delivery scalability issue when we have large number of
    interfaces and a large number of sockets bound to the same SAP.

  • b76f5a842   llc: convert the socket list to RCU locking ... Browse Code »

    For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism,
    which require some extra checks in the lookup code:

    a) If the current socket was released, reallocated & inserted in
    another list it will short circuit the iteration for the current list,
    thus we need to restart the lookup.

    b) If the current socket was released, reallocated & inserted in the
    same list we just need to recheck it matches the look-up criteria and
    if not we can skip to the next element.

    In this case there is no need to restart the lookup, since sockets are
    inserted at the start of the list and the worst that will happen is
    that we will iterate throught some of the list elements more then
    once.

    Note that the /proc and multicast delivery was not yet converted to
    RCU, it still uses spinlocks for protection.

  • f2ccd8fa0   [NET]: Kill skb->real_dev ... Browse Code »

    Bonding just wants the device before the skb_bond()
    decapsulation occurs, so simply pass that original
    device into packet_type->func() as an argument.

    It remains to be seen whether we can use this same
    exact thing to get rid of skb->input_dev as well.

    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!
