      Pull networking fixes from David Miller:
      
       1) L2TP doesn't get autoloaded when you try to open an L2TP socket due
          to a missing module alias, fix from Benjamin LaHaise.
      
       2) Netlabel and RDS should propagate gfp flags given to them by
          callers, fixes from Dan Carpeneter.
      
       3) Recursive locking fix in usbnet wasn't bulletproof and can result in
          objects going away mid-flight due to races, fix from Ming Lei.
      
       4) Fix up some confusion about a bool module parameter in netfilter's
          iptable_filter and ip6table_filter, from Rusty Russell.
      
       5) If SKB recycling is used via napi_reuse_skb() we end up with
          different amounts of headroom reserved than we had at the original
          SKB allocation.  Fix from Eric Dumazet.
      
       6) Fix races in TG3 driver ring refilling, from Michael Chan.
      
       7) We have callbacks for IPSEC replay notifiers, but some call sites
          were not using the ops method and instead were calling one of the
          implementations directly.  Oops.  Fix from Steffen Klassert.
      
       8) Fix IP address validation properly in the bonding driver, the
          previous fix only works with netlink where the subnet mask and IP
          address are changed in one atomic operation.  When 'ifconfig' ioctls
          are used the IP address and the subnet mask are changed in two
          distinct operations.  Fix from Andy Gospodarek.
      
       9) Provide a sky2 module operation to work around power management
          issues with some BIOSes.  From Stephen Hemminger.
      
      * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
        usbnet: consider device busy at each recieved packet
        bonding: remove entries for master_ip and vlan_ip and query devices instead
        netfilter: remove forward module param confusion.
        usbnet: don't clear urb->dev in tx_complete
        usbnet: increase URB reference count before usb_unlink_urb
        xfrm: Access the replay notify functions via the registered callbacks
        xfrm: Remove unused xfrm_state from xfrm_state_check_space
        RDS: use gfp flags from caller in conn_alloc()
        netlabel: use GFP flags from caller instead of GFP_ATOMIC
        l2tp: enable automatic module loading for l2tp_ppp

        tg3: Fix RSS ring refill race condition
        sky2: override for PCI legacy power management

      Linus Torvalds authored
      Pull NFS client updates for Linux 3.4 from Trond Myklebust:
       "New features include:
         - Add NFS client support for containers.
      
           This should enable most of the necessary functionality, including
           lockd support, and support for rpc.statd, NFSv4 idmapper and
           RPCSEC_GSS upcalls into the correct network namespace from which
           the mount system call was issued.
      
         - NFSv4 idmapper scalability improvements
      
           Base the idmapper cache on the keyring interface to allow
           concurrent access to idmapper entries.  Start the process of
           migrating users from the single-threaded daemon-based approach to
           the multi-threaded request-key based approach.
      
         - NFSv4.1 implementation id.
      
           Allows the NFSv4.1 client and server to mutually identify each
           other for logging and debugging purposes.
      
         - Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of
           having to use the more counterintuitive 'vers=4,minorversion=1'.
      
         - SUNRPC tracepoints.
      
           Start the process of adding tracepoints in order to improve
           debugging of the RPC layer.
      
         - pNFS object layout support for autologin.
      
        Important bugfixes include:
      
         - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to
           fail to wake up all tasks when applied to priority waitqueues.
      
         - Ensure that we handle read delegations correctly, when we try to
           truncate a file.
      
         - A number of fixes for NFSv4 state manager loops (mostly to do with
           delegation recovery)."

      mm: fix testorder interaction between two kswapd patches · 643ac9fc
      Hugh Dickins authored
      Adjusting cc715d99 "mm: vmscan: forcibly scan highmem if there are
      too many buffer_heads pinning highmem" for -stable reveals that it was
      slightly wrong once on top of fe2c2a10 "vmscan: reclaim at order 0
      when compaction is enabled", which specifically adds testorder for the
      zone_watermark_ok_safe() test.

      Pull regmap updates from Mark Brown:
       "Things are really quieting down with the regmap API, while we're still
        seeing a trickle of new features coming in they're getting much
        smaller than they were.  It's also nice to have some features which
        support other subsystems building infrastructure on top of regmap.
        Highlights include:
      
        - Support for padding between the register and the value when
          interacting with the device, sometimes needed for fast interfaces.
        - Support for applying register updates to the device when restoring
          the register state.  This is intended to be used to apply updates
          supplied by manufacturers for tuning the performance of the device
          (many of which are to undocumented registers which aren't otherwise
          covered).
        - Support for multi-register operations on cached registers.
        - Support for syncing only part of the register cache.
        - Stubs and parameter query functions intended to make it easier for
          other subsystems to build infrastructure on top of the regmap API.
      
        plus a few driver updates making use of the new features which it was

      Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter:
      
       - Some SBP-2 initiator fixes, side product from ongoing work on a target.
      
       - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
         stack (flush buffer completions); it was evidently rarely used but not
         actually unused.  Matching libraw1394 code is already available.

      bonding: remove entries for master_ip and vlan_ip and query devices instead · eaddcd76
      Andy Gospodarek authored
      The following patch aimed to resolve an issue where secondary, tertiary,
      etc. addresses added to bond interfaces could overwrite the
      bond->master_ip and vlan_ip values.
      
              commit 917fbdb3
              Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com>
              Date:   Wed Nov 23 23:37:15 2011 +0000
      
                  bonding: only use primary address for ARP
      
      That patch was good because it prevented bonds using ARP monitoring from
      sending frames with an invalid source IP address.  Unfortunately, it
      didn't always work as expected.
      
      When using an ioctl (like ifconfig does) to set the IP address and
      netmask, 2 separate ioctls are actually called to set the IP and netmask
      if the mask chosen doesn't match the standard mask for that class of
      address.  The first ioctl did not have a mask that matched the one in
      the primary address and would still cause the device address to be
      overwritten.  The second ioctl that was called to set the mask would
      then detect as secondary and ignored, but the damage was already done.
      
      This was not an issue when using an application that used netlink
      sockets as the setting of IP and netmask came down at once.  The
      inconsistent behavior between those two interfaces was something that
      needed to be resolved.
      
      While I was thinking about how I wanted to resolve this, Ralf Zeidler
      came with a patch that resolved this on a RHEL kernel by keeping a full
      shadow of the entries in dev->ifa_list for the bonding device and vlan
      devices in the bonding driver.  I didn't like the duplication of the
      list as I want to see the 'bonding' struct and code shrink rather than
      grow, but liked the general idea.
      
      As the Subject indicates this patch drops the master_ip and vlan_ip
      elements from the 'bonding' and 'vlan_entry' structs, respectively.
      This can be done because a device's address-list is now traversed to
      determine the optimal source IP address for ARP requests and for checks
      to see if the bonding device has a particular IP address.  This code
      could have all be contained inside the bonding driver, but it made more
      sense to me to EXPORT and call inet_confirm_addr since it did exactly
      what was needed.
      
      I tested this and a backported patch and everything works as expected.
      Ralf also helped with verification of the backported patch.
      
      Thanks to Ralf for all his help on this.

      Vosburgh and Dave Miller.
      
      v3: Fixup incorrect usage of rcu_read_unlock based on Dave Miller's
      suggestion.

      this works, but it's unclear, and the check that it's in range is not

      security: optimize avc_audit() common path · 48aab2f7
      Linus Torvalds authored
      avc_audit() did a lot of jumping around and had a big stack frame, all
      for the uncommon case.
      
      Split up the uncommon case (which we really can't make go fast anyway)
      into its own slow function, and mark the conditional branches
      appropriately for the common likely case.
      
      This causes avc_audit() to no longer show up as one of the hottest
      functions on the branch profiles (the new "perf -b" thing), and makes
      the cycle profiles look really nice and dense too.
      
      The whole audit path is still annoyingly very much one of the biggest
      costs of name lookup, so these things are worth optimizing for.  I wish
      we could just tell people to turn it off, but realistically we do need
      it: we just need to make sure that the overhead of the necessary evil is
      as low as possible.

      usbnet: increase URB reference count before usb_unlink_urb · 0956a8c2
      tom.leiming@gmail.com authored
      Commit 4231d47e(net/usbnet: avoid
      recursive locking in usbnet_stop()) fixes the recursive locking
      problem by releasing the skb queue lock, but it makes usb_unlink_urb
      racing with defer_bh, and the URB to being unlinked may be freed before
      or during calling usb_unlink_urb, so use-after-free problem may be
      triggerd inside usb_unlink_urb.
      
      The patch fixes the use-after-free problem by increasing URB
      reference count with skb queue lock held before calling
      usb_unlink_urb, so the URB won't be freed until return from
      usb_unlink_urb.

      xfrm: Access the replay notify functions via the registered callbacks · 1265fd61
      Steffen Klassert authored
      We call the wrong replay notify function when we use ESN replay
      handling. This leads to the fact that we don't send notifications
      if we use ESN. Fix this by calling the registered callbacks instead
      of xfrm_replay_notify().

      xfrm: Remove unused xfrm_state from xfrm_state_check_space · 26b2072e
      Steffen Klassert authored
      The xfrm_state argument is unused in this function, so remove it.
      Also the name xfrm_state_check_space does not really match what this
      function does. It actually checks if we have enough head and tailroom
      on the skb. So we rename the function to xfrm_skb_check_space.

      RDS: use gfp flags from caller in conn_alloc() · f0229eaa
      Dan Carpenter authored
      We should be using the gfp flags the caller specified here, instead of
      GFP_KERNEL.  I think this might be a bugfix, depending on the value of
      "sock->sk->sk_allocation" when we call rds_conn_create_outgoing() in
      rds_sendmsg().  Otherwise, it's just a cleanup.

      netlabel: use GFP flags from caller instead of GFP_ATOMIC · 64b5fad5
      Dan Carpenter authored
      This function takes a GFP flags as a parameter, but they are never used.
      We don't take a lock in this function so there is no reason to prefer
      GFP_ATOMIC over the caller's GFP flags.
      
      There is only one caller, cipso_v4_map_cat_rng_ntoh(), and it passes
      GFP_ATOMIC as the GFP flags so this doesn't change how the code works.
      It's just a cleanup.

      vfs: tidy up sparse warnings in fs/namei.c · f7493e5d
      Linus Torvalds authored
      While doing the fs/namei.c cleanups, I ran sparse on it, and it pointed
      out other large integers and a couple of cases of us using '0' instead
      of the proper 'NULL'.
      
      Sparse still doesn't understand some of the conditional locking going
      on, but that's no excuse for not fixing up the trivial stuff.

      Pull nouveau destaging + Kelper modesetting support from Dave Airlie:
       "This pull request is unexpected and not something I had mentioned
        previously.
      
        So NVIDIA announced new Kepler GPUs this morning, and Ben has killed
        himself getting modesetting support for them together to have on
        launch day.  Most of the code to support the new chips has already
        gone in, however this pull contains a few more pieces along with the
        final enables so the driver binds to the new Kepler cards.  Its quite
        amazing that nouveau can support a GPU on its launch day even if its
        just unaccelerated modesetting, and I'd like to have support in the
        next kernel.
      
        In order to sweeten the deal, Ben has also requested nouveau destage
        and become ABI stable, the only change is the version number bump
        which he prepared userspace for quite a long time ago.  The driver
        hasn't broken ABI since that one big break that caused a lot of fuss.
      
        It's also quite a small set of code, and not likely to break anything."

      Pull drm main changes from Dave Airlie:
       "This is the main drm pull request, I'm probably going to send two more
        smaller ones, will explain below.
      
        This contains a patch that is also in the fbdev tree, but it should be
        the same patch, it added an API for hot unplugging framebuffer
        devices, and I need that API for a new driver.
      
        It also contains some changes to the i2c tree which Jean has acked,
        and one change to moorestown platform stuff in x86.
      
        Highlights:
         - new drivers: UDL driver for USB displaylink devices, kms only,
           should support correct hotplug operations.
         - core: i2c speedups + better hotplug support, EDID overriding via
           firmware interface - allows user to load a firmware for a broken
           monitor/kvm from userspace, it even has documentation for it.
         - exynos: new HDMI audio + hdmi 1.4 + virtual output driver
         - gma500: code cleanup
         - radeon: cleanups, CS optimisations, streamout support and pageflip
           fix
         - nouveau: NVD9 displayport support + more reclocking work
         - i915: re-enabling GMBUS, finish gpu patch (might help hibernation
           who knows), missed irq fixes, stencil tiling fixes, interlaced
           support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
           semaphore fixes
      
        As well as the usual bunch of cleanups and fixes all over the place.
      
        I've got two things I'd like to merge a bit later:
      
         a) AMD support for all their new radeonhd 7000 series GPU and APUs.
            AMD dropped this a bit late due to insane internal review
            processes, (please AMD just follow Intel and let open source guys
            ship stuff early) however I don't want to penalise people who own
            this hardware (since its been on sale for 3-4 months and GPU hw
            doesn't exactly have a lifetime in years) and consign them to
            using closed drivers for longer than necessary.  The changes are
            well contained and just plug into the driver new gpu functionality
            so they should be fairly regression proof.  I just want to give
            them a bit of a run on the hw AMD kindly sent me.
      
         b) drm prime/dma-buf interface code.  This is just infrastructure
            code to expose the dma-buf stuff to drm drivers and to userspace.
            I'm not planning on pushing any driver support in this cycle
            (except maybe exynos), but I'd like to get the infrastructure code
            in so for the next cycle I can start getting the driver support
            into the individual drivers.  We have started driver support for
            i915, nouveau and udl along with I think exynos and omap in
            staging.  However this code relies on the dma-buf tree being
            pulled into your tree first since it needs the latest interfaces
            from that tree.  I'll push to get that tree sent asap.
      
        (oh and any warnings you see in i915 are gcc's fault from what anyone
        can see)."
      
      Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
      msic_thermal_platform_data() thermal function being added next to the
      tc35876x_platform_data() i2c device function..

      kdb: Add message about CONFIG_DEBUG_RODATA on failure to install breakpoint · 1ba0c172
      Jason Wessel authored
      On x86, if CONFIG_DEBUG_RODATA is set, one cannot set breakpoints
      via KDB.  Apparently this is a well-known problem, as at least one distribution
      now ships with both KDB enabled and CONFIG_DEBUG_RODATA=y for security reasons.
      
      This patch adds an printk message to the breakpoint failure case,
      in order to provide suggestions about how to use the debugger.
