      Pull more networking fixes from David Miller:
      
       1) Eric Dumazet discovered and fixed what turned out to be a family of
          bugs.  These functions were using pskb_may_pull() which might need
          to reallocate the linear SKB data buffer, but the callers were not
          expecting this possibility.  The callers have cached pointers to the
          packet header areas, and would need to reload them if we were to
          continue using pskb_may_pull().
      
          So they could end up reading garbage.
      
          It's easier to just change these RAW4/RAW6/MIP6 routines to use
          skb_header_pointer() instead of pskb_may_pull(), which won't modify
          the linear SKB data area.
      
       2) Dave Jone's syscall spammer caught a case where a non-TCP socket can
          call down into the TCP keepalive code.  The case basically involves
          creating a raw socket with sk_protocol == IPPROTO_TCP, then calling
          setsockopt(sock_fd, SO_KEEPALIVE, ...)
      
          Fixed by Eric Dumazet.
      
       3) Bluetooth devices do not get configured properly while being powered
          on, resulting in always using legacy pairing instead of SSP.  Fix
          from Andrzej Kaczmarek.
      
       4) Bluetooth cancels delayed work erroneously, put stricter checks in
          place.  From Andrei Emeltchenko.
      
       5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in
          cfg80211, from Luis R.  Rodriguez.
      
       6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach.
      
       7) Missing module license in bcm87xx driver, from Peter Huewe.
      
       8) Team driver can lose port changed events when adding devices to a
          team, fix from Jiri Pirko.
      
       9) Fix endless loop when trying ot unregister PPPOE device in zombie
          state, from Xiaodong Xu.
      
      10) batman-adv layer needs to set MAC address of software device
          earlier, otherwise we call tt_local_add with it uninitialized.
      
      11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but
          that doesn't program the device properly.  From Marek Vasut.

      ipv6: mip6: fix mip6_mh_filter() · 96af69ea
      Eric Dumazet authored
      mip6_mh_filter() should not modify its input, or else its caller
      would need to recompute ipv6_hdr() if skb->head is reallocated.
      
      Use skb_header_pointer() instead of pskb_may_pull()

      icmpv6_filter() should not modify its input, or else its caller
      would need to recompute ipv6_hdr() if skb->head is reallocated.
      
      Use skb_header_pointer() instead of pskb_may_pull() and
      change the prototype to make clear both sk and skb are const.
      
      Also, if icmpv6 header cannot be found, do not deliver the packet,
      as we do in IPv4.

      c/r: prctl: fix build error for no-MMU case · be8cfc4a
      Mark Salter authored
      Commit 1ad75b9e ("c/r: prctl: add minimal address test to
      PR_SET_MM") added some address checking to prctl_set_mm() used by
      checkpoint-restore.  This causes a build error for no-MMU systems:
      
         kernel/sys.c: In function 'prctl_set_mm':
         kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function)
      
      The test for mmap_min_addr doesn't make a lot of sense for no-MMU code
      as noted in commit 6e141546 ("NOMMU: Optimise away the
      {dac_,}mmap_min_addr tests").
      
      This patch defines mmap_min_addr as 0UL in the no-MMU case so that the
      compiler will optimize away tests for "addr < mmap_min_addr".

      lib/flex_proportions.c: fix corruption of denominator in flexible proportions · b5bd6a0e
      Jan Kara authored
      When racing with CPU hotplug, percpu_counter_sum() can return negative
      values for the number of observed events.
      
      This confuses fprop_new_period(), which uses unsigned type and as a
      result number of events is set to big *positive* number.  From that
      moment on, things go pear shaped and can result e.g.  in division by
      zero as denominator is later truncated to 32-bits.
      
      This bug causes a divide-by-zero oops in bdi_dirty_limit() in Borislav's
      3.6.0-rc6 based kernel.
      
      Fix the issue by using a signed type in fprop_new_period().  That makes
      us bail out from the function without doing anything (mistakenly)
      thinking there are no events to age.  That makes aging somewhat
      inaccurate but getting accurate data would be rather hard.
