      Pull networking fixes from David Miller:
      
      1) GRE tunnel drivers don't set the transport header properly, they also
         blindly deref the inner protocol ipv4 and needs some checks.  Fixes
         from Isaku Yamahata.
      
      2) Fix sleeps while atomic in netdevice rename code, from Eric Dumazet.
      
      3) Fix double-spinlock in solos-pci driver, from Dan Carpenter.
      
      4) More ARP bug fixes.  Fix lockdep splat in arp_solicit() and then the
         bug accidentally added by that fix.  From Eric Dumazet and Cong Wang.
      
      5) Remove some __dev* annotations that slipped back in, as well as all
         HOTPLUG references.  From Greg KH
      
      6) RDS protocol uses wrong interfaces to access scatter-gather elements,
         causing a regression.  From Mike Marciniszyn.
      
      7) Fix build error in cpts driver, from Richard Cochran.
      
      8) Fix arithmetic in packet scheduler, from Stefan Hasko.
      
      9) Similarly, fix association during calculation of random backoff in
         batman-adv.  From Akinobu Mita.

      i2c: remove __dev* attributes from subsystem · 0b255e92
      Bill Pemberton authored
      CONFIG_HOTPLUG is going away as an option.  As result the __dev*
      markings will be going away.
      
      Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
      and __devexit.

      This reverts commit 79f77bf9.
      
      This is obviously wrong, and I have no idea how I missed seeing the
      warning in testing: I must just not have looked at the right logs.  The
      caller bumps rq_resused/rq_next_page, so it will always be hit on a
      large enough read.

      Bug is from arp_solicit(), releasing the neigh lock after arp_send()
      In case of vxlan, we eventually need to write lock a neigh lock later.
      
      Its a false positive, but we can get rid of it without lockdep
      annotations.
      
      We can instead use neigh_ha_snapshot() helper.

      tuntap: dont use a private kmem_cache · 9fdc6bef
      Eric Dumazet authored
      Commit 96442e42 (tuntap: choose the txq based on rxq)
      added a per tun_struct kmem_cache.
      
      As soon as several tun_struct are used, we get an error
      because two caches cannot have same name.
      
      Use the default kmalloc()/kfree_rcu(), as it reduce code
      size and doesn't have performance impact here.

      net: devnet_rename_seq should be a seqcount · 30e6c9fa
      Eric Dumazet authored
      Using a seqlock for devnet_rename_seq is not a good idea,
      as device_rename() can sleep.
      
      As we hold RTNL, we dont need a protection for writers,
      and only need a seqcount so that readers can catch a change done
      by a writer.
      
      Bug added in commit c91f6df2 (sockopt: Change getsockopt() of
      SO_BINDTODEVICE to return an interface name)

      ip_gre: fix possible use after free · f7e75ba1
      Eric Dumazet authored
      Once skb_realloc_headroom() is called, tiph might point to freed memory.
      
      Cache tiph->ttl value before the reallocation, to avoid unexpected
      behavior.

      ip_gre: make ipgre_tunnel_xmit() not parse network header as IP unconditionally · 412ed947
      Isaku Yamahata authored
      ipgre_tunnel_xmit() parses network header as IP unconditionally.
      But transmitting packets are not always IP packet. For example such packet
      can be sent by packet socket with sockaddr_ll.sll_protocol set.
      So make the function check if skb->protocol is IP.

      dm snapshot: do not use map_context · ee18026a
      Mikulas Patocka authored
      Eliminate struct map_info from dm-snap.
      
      map_info->ptr was used in dm-snap to indicate if the bio was tracked.
      If map_info->ptr was non-NULL, the bio was linked in tracked_chunk_hash.
      
      This patch removes the use of map_info->ptr. We determine if the bio was
      tracked based on hlist_unhashed(&c->node). If hlist_unhashed is true,
      the bio is not tracked, if it is false, the bio is tracked.

      dm raid1: dont use map_context · 0045d61b
      Mikulas Patocka authored
      Don't use map_info any more in dm-raid1.
      
      map_info was used for writes to hold the region number. For this purpose
      we add a new field dm_bio_details to dm_raid1_bio_record.
      
      map_info was used for reads to hold a pointer to dm_raid1_bio_record (if
      the pointer was non-NULL, bio details were saved; if the pointer was
      NULL, bio details were not saved). We use
      dm_raid1_bio_record.details->bi_bdev for this purpose. If bi_bdev is
      NULL, details were not saved, if bi_bdev is non-NULL, details were
      saved.
