       "A moderately sized pile of fixes, some specifically for merge window
        introduced regressions although others are for longer standing items
        and have been queued up for -stable.
      
        I'm kind of tired of all the RDS protocol bugs over the years, to be
        honest, it's way out of proportion to the number of people who
        actually use it.
      
         1) Fix missing range initialization in netfilter IPSET, from Jozsef
            Kadlecsik.
      
         2) ieee80211_local->tim_lock needs to use BH disabling, from Johannes

         6) Fix UDP checksumming in bnx2x driver for 57710 and 57711 chips,
            fix from Dmitry Kravkov.
      
         7) Missing cfgspace_lock initialization in BCMA driver.
      
         8) Validate parameter size for SCTP assoc stats getsockopt(), from
            Guenter Roeck.
      
         9) Fix SCTP association hangs, from Lee A Roberts.
      
        10) Fix jumbo frame handling in r8169, from Francois Romieu.
      
        11) Fix phy_device memory leak, from Petr Malat.
      
        12) Omit trailing FCS from frames received in BGMAC driver, from Hauke
            Mehrtens.
      
        13) Missing socket refcount release in L2TP, from Guillaume Nault.
      
        14) sctp_endpoint_init should respect passed in gfp_t, rather than use
            GFP_KERNEL unconditionally.  From Dan Carpenter.
      
        15) Add AISX AX88179 USB driver, from Freddy Xin.
      
        16) Remove MAINTAINERS entries for drivers deleted during the merge
            window, from Cesar Eduardo Barros.
      
        17) RDS protocol can try to allocate huge amounts of memory, check
            that the user's request length makes sense, from Cong Wang.
      
        18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own,
            bogus, definition.  From Cong Wang.
      
        19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll,
            from Frank Li.  Also, fix a build error introduced in the merge
            window.
      
        20) Fix bogus purging of default routes in ipv6, from Lorenzo Colitti.
      
        21) Don't double count RTT measurements when we leave the TCP receive
            fast path, from Neal Cardwell."

        the first commit in the series and the minimal necessary bugfix, which

        The remanining commits enforce irq disabling in irq_exit(), sanitize

      hw_random: make buffer usable in scatterlist. · f7f154f1
      Rusty Russell authored
      virtio_rng feeds the randomness buffer handed by the core directly
      into the scatterlist, since commit bb347d98.
      
      However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address
      (at least on most archs).  We could fix this in virtio_rng, but it's actually
      far easier to just do it in the core as virtio_rng would have to allocate
      a buffer every time (it doesn't know how much the core will want to read).

      Neal Cardwell authored
      We should not update ts_recent and call tcp_rcv_rtt_measure_ts() both
      before and after going to step5. That wastes CPU and double-counts the
      receiver-side RTT sample.

      net: ipv6: Don't purge default router if accept_ra=2 · 3e8b0ac3
      Lorenzo Colitti authored
      Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel
      to accept RAs even when forwarding is enabled. However, enabling
      forwarding purges all default routes on the system, breaking
      connectivity until the next RA is received. Fix this by not
      purging default routes on interfaces that have accept_ra=2.

      rds: limit the size allocated by rds_message_alloc() · ece6b0a2
      Cong Wang authored
      Dave Jones reported the following bug:
      
      "When fed mangled socket data, rds will trust what userspace gives it,
      and tries to allocate enormous amounts of memory larger than what
      kmalloc can satisfy."

       "You'll be glad to here that the end is nigh for the UAPI patches.
        Only the fbdev/framebuffer piece remains now that the SCSI stuff has

        appears that Florian hasn't had time to deal with my patch, but back
        in December he did say he didn't mind if I pushed it forward."
      
      Yay.  No more uapi movement.  And hopefully no more big header file

      ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver · e2ca90c2
      Freddy Xin authored
      This is a resubmission.
      Added kfree() in ax88179_get_eeprom to prevent memory leakage.
      Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
      Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
      Fixed endianness issue on big endian systems and verified this driver on iBook G4.
      Removed steps that change net->features in ax88179_set_features function.
      Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
      Fixed the issue that the default MTU is not 1500.
      Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
      MTU higher than 1500.
      Fixed indentation and empty line coding style errors.
      The _nopm version usb functions were added to access register in suspend and resume functions.
      Serveral variables allocted dynamically were removed and replaced by stack variables.
      ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.
      
      This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
      to gigabit ethernet adapters. It's based on the AX88xxx driver but
      the usb commands used to access registers for AX88179 are completely different.
      This driver had been verified on x86 system with AX88179/AX88178A and
      Sitcomm LN-032 USB dongles.

      Pull btrfs update from Chris Mason:
       "The biggest feature in the pull is the new (and still experimental)
        raid56 code that David Woodhouse started long ago.  I'm still working
        on the parity logging setup that will avoid inconsistent parity after
        a crash, so this is only for testing right now.  But, I'd really like
        to get it out to a broader audience to hammer out any performance
        issues or other problems.
      
        scrub does not yet correct errors on raid5/6 either.
      
        Josef has another pass at fsync performance.  The big change here is
        to combine waiting for metadata with waiting for data, which is a big
        latency win.  It is also step one toward using atomics from the
        hardware during a commit.
      
        Mark Fasheh has a new way to use btrfs send/receive to send only the
        metadata changes.  SUSE is using this to make snapper more efficient
        at finding changes between snapshosts.
      
        Snapshot-aware defrag is also included.
      
        Otherwise we have a large number of fixes and cleanups.  Eric Sandeen
        wins the award for removing the most lines, and I'm hoping we steal
        this idea from XFS over and over again."
