    Pull more rdma updates from Doug Ledford:
    "This is the second group of code for the 4.7 merge window. It looks
    large, but only in one sense. I'll get to that in a minute. The list
    of changes here breaks down as follows:

    - Dynamic counter infrastructure in the IB drivers

    This is a sysfs based code to allow free form access to the
    hardware counters RDMA devices might support so drivers don't need
    to code this up repeatedly themselves

    - SendOnlyFullMember multicast support

    - IB router support

    - A couple misc fixes

    - The big item on the list: hfi1 driver updates, plus moving the hfi1
    driver out of staging

    There was a group of 15 patches in the hfi1 list that I thought I had
    in the first pull request but they weren't. So that added to the
    length of the hfi1 section here.

    As far as these go, everything but the hfi1 is pretty straight
    forward.

    The hfi1 is, if you recall, the driver that Al had complaints about
    how it used the write/writev interfaces in an overloaded fashion. The
    write portion of their interface behaved like the write handler in the
    IB stack proper and did bi-directional communications. The writev
    interface, on the other hand, only accepts SDMA request structures.
    The completions for those structures are sent back via an entirely
    different event mechanism.

    With the security patch, we put security checks on the write
    interface, however, we also knew they would be going away soon. Now,
    we've converted the write handler in the hfi1 driver to use ioctls
    from the IB reserved magic area for its bidirectional communications.
    With that change, Intel has addressed all of the items originally on
    their TODO when they went into staging (as well as many items added to
    the list later).

    As such, I moved them out, and since they were the last item in the
    staging/rdma directory, and I don't have immediate plans to use the
    staging area again, I removed the staging/rdma area.

    Because of the move out of staging, as well as a series of 5 patches
    in the hfi1 driver that removed code people thought should be done in
    a different way and was optional to begin with (a snoop debug
    interface, an eeprom driver for an eeprom connected directory to their
    hfi1 chip and not via an i2c bus, and a few other things like that),
    the line count, especially the removal count, is high"

  • b40f4757d   IB/core: Make device counter infrastructure dynamic ... Browse Code »

    In practice, each RDMA device has a unique set of counters that the
    hardware implements. Having a central set of counters that they must
    all adhere to is limiting and causes many useful counters to not be
    available.

    Therefore we create a dynamic counter registration infrastructure.

    The driver must implement a stats structure allocation routine, in
    which the driver must place the directory name it wants, a list of
    names for all of the counters, an array of u64 counters themselves,
    plus a few generic configuration options.

    We then implement a core routine to create a sysfs file for each
    of the named stats elements, and a core routine to retrieve the
    stats when any of the sysfs attribute files are read.

    To avoid excessive beating on the stats generation routine in the
    drivers, the core code also caches the stats for a short period of
    time so that someone attempting to read all of the stats in a
    given device's directory will not result in a stats generation
    call per file read.

    Future work will attempt to standardize just the shared stats
    elements, and possibly add a method to get the stats via netlink
    in addition to sysfs.

  • 9baa0b036   IB/ipoib: Add rtnl_link_ops support ... Browse Code »

    Add rtnl_link_ops to IPoIB, with the first usage being child device
    create/delete through them. Childs devices are now either legacy ones,
    created/deleted through the ipoib sysfs entries, or RTNL ones.

    Adding support for RTNL childs involved refactoring of ipoib_vlan_add
    which is now used by both the sysfs and the link_ops code.

    Also, added ndo_uninit entry to support calling unregister_netdevice_queue
    from the rtnl dellink entry. This required removal of calls to
    ipoib_dev_cleanup from the driver in flows which use unregister_netdevice,
    since the networking core will invoke ipoib_uninit which does exactly that.

    Below you will find an updated version from the original series bunching all patches into one big patch
    updating broken web addresses that are located in Documentation/*
    Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
    the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
    Now there are also some addresses pointing to .spec files some are located, but some(after searching
    on the companies site)where still no where to be found. In this case I just changed the address
    to the company site this way the users can contact the company and they can locate them for the users.

  • 2be8e3ee8   IB/umad: Add P_Key index support ... Browse Code »

    Add support for setting the P_Key index of sent MADs and getting the
    P_Key index of received MADs. This requires a change to the layout of
    the ABI structure struct ib_user_mad_hdr, so to avoid breaking
    compatibility, we default to the old (unchanged) ABI and add a new
    ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware
    of the new ABI to opt into using it.

    We plan on switching to the new ABI by default in a year or so, and
    this patch adds a warning that is printed when an application uses the
    old ABI, to push people towards converting to the new ABI.

    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!
