      Pull networking update from David Miller:
       "A couple weeks of bug fixing in there.  The largest chunk is all the
        broken crap Amerigo Wang found in the netpoll layer."
      
       1) netpoll and it's users has several serious bugs:
          a) uses GFP_KERNEL with locks held
          b) interfaces requiring interrupts disabled are called with them
             enabled
          c) and vice versa
          d) VLAN tag demuxing, as per all other RX packet input paths, is not
             applied
      
          All from Amerigo Wang.
      
       2) Hopefully cure the ipv4 mapped ipv6 address TCP early demux bugs for
          good, from Neal Cardwell.
      
       3) Unlike AF_UNIX, AF_PACKET sockets don't set a default credentials
          when the user doesn't specify one explicitly during sendmsg().
          Instead we attach an empty (zero) SCM credential block which is
          definitely not what we want.  Fix from Eric Dumazet.
      
       4) IPv6 illegally invokes netdevice notifiers with RCU lock held, fix
          from Ben Hutchings.
      
       5) inet_csk_route_child_sock() checks wrong inet options pointer, fix
          from Christoph Paasch.
      
       6) When AF_PACKET is used for transmit, packet loopback doesn't behave
          properly when a socket fanout is enabled, from Eric Leblond.
      
       7) On bluetooth l2cap channel create failure, we leak the socket, from
          Jaganath Kanakkassery.
      
       8) Fix all the netprio file handling bugs found by Al Viro, from John
          Fastabend.
      
       9) Several error return and NULL deref bug fixes in networking drivers
          from Julia Lawall.
      
      10) A large smattering of struct padding et al.  kernel memory leaks to
          userspace found of Mathias Krause.
      
      11) Conntrack expections in netfilter can access an uninitialized timer,
          fix from Pablo Neira Ayuso.
      
      12) Several netfilter SIP tracker bug fixes from Patrick McHardy.
      
      13) IPSEC ipv6 routes are not initialized correctly all the time,
          resulting in an OOPS in inet_putpeer().  Also from Patrick McHardy.
      
      14) Bridging does rcu_dereference() outside of RCU protected area, from
          Stephen Hemminger.
      
      15) Fix routing cache removal performance regression when looking up
          output routes that have a local destination.  From Zheng Yan.

      af_netlink: force credentials passing [CVE-2012-3520] · e0e3cea4
      Eric Dumazet authored
      Pablo Neira Ayuso discovered that avahi and
      potentially NetworkManager accept spoofed Netlink messages because of a
      kernel bug.  The kernel passes all-zero SCM_CREDENTIALS ancillary data
      to the receiver if the sender did not provide such data, instead of not
      including any such data at all or including the correct data from the
      peer (as it is the case with AF_UNIX).
      
      This bug was introduced in commit 16e57262
      (af_unix: dont send SCM_CREDENTIALS by default)
      
      This patch forces passing credentials for netlink, as
      before the regression.
      
      Another fix would be to not add SCM_CREDENTIALS in
      netlink messages if not provided by the sender, but it
      might break some programs.
      
      With help from Florian Weimer & Petr Matousek
      
      This issue is designated as CVE-2012-3520

      ipv4: fix ip header ident selection in __ip_make_skb() · a9915a1b
      Eric Dumazet authored
      Christian Casteyde reported a kmemcheck 32-bit read from uninitialized
      memory in __ip_select_ident().
      
      It turns out that __ip_make_skb() called ip_select_ident() before
      properly initializing iph->daddr.
      
      This is a bug uncovered by commit 1d861aa4 (inet: Minimize use of
      cached route inetpeer.)

      ipv4: Use newinet->inet_opt in inet_csk_route_child_sock() · 1a7b27c9
      Christoph Paasch authored
      Since 0e734419 ("ipv4: Use inet_csk_route_child_sock() in DCCP and
      TCP."), inet_csk_route_child_sock() is called instead of
      inet_csk_route_req().
      
      However, after creating the child-sock in tcp/dccp_v4_syn_recv_sock(),
      ireq->opt is set to NULL, before calling inet_csk_route_child_sock().
      Thus, inside inet_csk_route_child_sock() opt is always NULL and the
      SRR-options are not respected anymore.
      Packets sent by the server won't have the correct destination-IP.
      
      This patch fixes it by accessing newinet->inet_opt instead of ireq->opt
      inside inet_csk_route_child_sock().

      [ 2866.310254] BUG TCP (Not tainted): Object already free
      [ 2866.310254] -----------------------------------------------------------------------------
      [ 2866.310254]
      
      The bug comes from the fact that timer set in sk_reset_timer() can run
      before we actually do the sock_hold(). socket refcount reaches zero and
      we free the socket too soon.
      
      timer handler is not allowed to reduce socket refcnt if socket is owned
      by the user, or we need to change sk_reset_timer() implementation.
      
      We should take a reference on the socket in case TCP_DELACK_TIMER_DEFERRED
      or TCP_DELACK_TIMER_DEFERRED bit are set in tsq_flags
      
      Also fix a typo in tcp_delack_timer(), where TCP_WRITE_TIMER_DEFERRED
      was used instead of TCP_DELACK_TIMER_DEFERRED.
      
      For consistency, use same socket refcount change for TCP_MTU_REDUCED_DEFERRED,
      even if not fired from a timer.

       "This update became slightly bigger than usual for rc3, but most of the
        commits are small and trivial.  A large chunk is found for HD-audio
        ca0132 codec, which is mostly a clean up of the specific code, to make
        SPDIF working properly, and also in the new ASoC Arizona driver.
      
        One important fix is for usb-audio Oops fix since 3.5.  We still see
        some EHCI related bandwidth problem, but usb-audio should be more
        stabilized now.
      
        Other than that, a Kconfig fix is spread over files, and various
        HD-audio and ASoC fixes as usual, in addition to Julia's error path
        fixes."

      task_work: add a scheduling point in task_work_run() · f341861f
      Eric Dumazet authored
      It seems commit 4a9d4b02 ("switch fput to task_work_add") re-
      introduced the problem addressed in 944be0b2 ("close_files(): add
      scheduling point")
      
      If a server process with a lot of files (say 2 million tcp sockets) is
      killed, we can spend a lot of time in task_work_run() and trigger a soft
      lockup.

      fbcon: fix race condition between console lock and cursor timer · ec5da7f8
      Dave Airlie authored
      So we've had a fair few reports of fbcon handover breakage between
      efi/vesafb and i915 surface recently, so I dedicated a couple of
      days to finding the problem.
      
      Essentially the last thing we saw was the conflicting framebuffer
      message and that was all.
      
      So after much tracing with direct netconsole writes (printks
      under console_lock not so useful), I think I found the race.
      
        Thread A (driver load)    Thread B (timer thread)
          unbind_con_driver ->              |
          bind_con_driver ->                |
          vc->vc_sw->con_deinit ->          |
          fbcon_deinit ->                   |
          console_lock()                    |
              |                             |
              |                       fbcon_flashcursor timer fires
              |                       console_lock() <- blocked for A
              |
              |
        fbcon_del_cursor_timer ->
          del_timer_sync
          (BOOM)
      
      Of course because all of this is under the console lock,
      we never see anything, also since we also just unbound the active
      console guess what we never see anything.
      
      Hopefully this fixes the problem for anyone seeing vesafb->kms
      driver handoff.

      ALSA: snd-als100: fix suspend/resume · 53e1719f
      Ondrej Zary authored
      snd_card_als100_probe() does not set pcm field in struct snd_sb.
      As a result, PCM is not suspended and applications don't know that they need
      to resume the playback.
      
      Tested with Labway A381-F20 card (ALS120).
