      spi: Updates for v3.15
      A busy release for both cleanups and new drivers this time along with
      further factoring out of replicated code into the core:
       - Provide support in the core for DMA mapping transfers - essentially
         all drivers weren't implementing this properly, now there's no
       - Dual and quad mode support for spidev.
       - Fix handling of cs_change in the generic implementation.
       - Remove the S3C_DMA code from the s3c64xx driver now that all the
         platforms using it have been converted to dmaengine.
       - Lots of improvements to the Renesas SPI controllers.
       - Drivers for Allwinner A10 and A31, Qualcomm QUP and Xylinx xtfpga.
       - Removal of the bitrotted ti-ssp driver.

      AUDIT: Allow login in non-init namespaces · aa4af831
      Eric Paris authored
      It its possible to configure your PAM stack to refuse login if audit
      messages (about the login) were unable to be sent.  This is common in
      many distros and thus normal configuration of many containers.  The PAM
      modules determine if audit is enabled/disabled in the kernel based on
      the return value from sending an audit message on the netlink socket.
      If userspace gets back ECONNREFUSED it believes audit is disabled in the
      kernel.  If it gets any other error else it refuses to let the login
      Just about ever since the introduction of namespaces the kernel audit
      subsystem has returned EPERM if the task sending a message was not in
      the init user or pid namespace.  So many forms of containers have never
      worked if audit was enabled in the kernel.
      BUT if the container was not in net_init then the kernel network code
      would send ECONNREFUSED (instead of the audit code sending EPERM).  Thus
      by pure accident/dumb luck/bug if an admin configured the PAM stack to
      reject all logins that didn't talk to audit, but then ran the login
      untility in the non-init_net namespace, it would work!! Clearly this was
      a bug, but it is a bug some people expected.
      With the introduction of network namespace support in 3.14-rc1 the two
      bugs stopped cancelling each other out.  Now, containers in the
      non-init_net namespace refused to let users log in (just like PAM was
      configfured!) Obviously some people were not happy that what used to let
      users log in, now didn't!
      This fix is kinda hacky.  We return ECONNREFUSED for all non-init
      relevant namespaces.  That means that not only will the old broken
      non-init_net setups continue to work, now the broken non-init_pid or
      non-init_user setups will 'work'.  They don't really work, since audit
      isn't logging things.  But it's what most users want.
      In 3.15 we should have patches to support not only the non-init_net
      (3.14) namespace but also the non-init_pid and non-init_user namespace.
      So all will be right in the world.  This just opens the doors wide open
      on 3.14 and hopefully makes users happy, if not the audit system...

      ext4: atomically set inode->i_flags in ext4_set_inode_flags() · 00a1a053
      Theodore Ts'o authored
      Use cmpxchg() to atomically set i_flags instead of clearing out the
      S_IMMUTABLE, S_APPEND, etc. flags and then setting them from the
      EXT4_IMMUTABLE_FL, EXT4_APPEND_FL flags, since this opens up a race
      where an immutable file has the immutable flag cleared for a brief
      window of time.

      Pull networking fixes from David Miller:
       1) We've discovered a common error in several networking drivers, they
          put VLAN offload features into ->vlan_features, which would suggest
          that they support offloading 2 or more levels of VLAN encapsulation.
          Not only do these devices not do that, but we don't have the
          infrastructure yet to handle that at all.
          Fixes from Vlad Yasevich.
       2) Fix tcpdump crash with bridging and vlans, also from Vlad.
       3) Some MAINTAINERS updates for random32 and bonding.

       5) Bridge doesn't handle stacked vlans properly, fix from Toshiaki
       6) Fix deadlock in openvswitch, from Flavio Leitner.
       7) get_timewait4_sock() doesn't report delay times correctly, fix from
          Eric Dumazet.
       8) Duplicate address detection and addrconf verification need to run in
          contexts where RTNL can be obtained.  Move them to run from a

      bridge: Fix crash with vlan filtering and tcpdump · fc92f745
      Vlad Yasevich authored
      When the vlan filtering is enabled on the bridge, but
      the filter is not configured on the bridge device itself,
      running tcpdump on the bridge device will result in a
      an Oops with NULL pointer dereference.  The reason
      is that br_pass_frame_up() will bypass the vlan
      check because promisc flag is set.  It will then try
      to get the table pointer and process the packet based
      on the table.  Since the table pointer is NULL, we oops.
      Catch this special condition in br_handle_vlan().

      net: Account for all vlan headers in skb_mac_gso_segment · 53d6471c
      Vlad Yasevich authored
      skb_network_protocol() already accounts for multiple vlan
      headers that may be present in the skb.  However, skb_mac_gso_segment()
      doesn't know anything about it and assumes that skb->mac_len
      is set correctly to skip all mac headers.  That may not
      always be the case.  If we are simply forwarding the packet (via
      bridge or macvtap), all vlan headers may not be accounted for.
      A simple solution is to allow skb_network_protocol to return
      the vlan depth it has calculated.  This way skb_mac_gso_segment
      will correctly skip all mac headers.
