      Pull networking fixes from David Miller:
 "Things seem to be settling down as far as networking is concerned,
  let's hope this trend continues...

   1) Add iov_iter_revert() and use it to fix the behavior of
      skb_copy_datagram_msg() et al., from Al Viro.

   2) Fix the protocol used in the synthetic SKB we cons up for the
      purposes of doing a simulated route lookup for RTM_GETROUTE
      requests. From Florian Larysch.

   3) Don't add noop_qdisc to the per-device qdisc hashes, from Cong
      Wang.

   4) Don't call netdev_change_features with the team lock held, from
      Xin Long.

   5) Revert TCP F-RTO extension to catch more spurious timeouts because
      it interacts very badly with some middle-boxes. From Yuchung
      Cheng.

   6) Fix the loss of error values in l2tp {s,g}etsockopt calls, from
      Guillaume Nault.

   7) ctnetlink uses bit positions where it should be using bit masks,
      fix from Liping Zhang.

   8) Missing RCU locking in netfilter helper code, from Gao Feng.

   9) Avoid double frees and use-after-frees in tcp_disconnect(), from
      Eric Dumazet.

  10) Don't do a changelink before we register the netdevice in
      bridging, from Ido Schimmel.

  11) Lock the ipv6 device address list properly, from Rabin Vincent"

      Pull x86 fixes from Thomas Gleixner:
 "A set of small fixes for x86:

   - fix locking in RDT to prevent memory leaks and freeing in use
     memory

   - prevent setting invalid values for vdso32_enabled which cause
     inconsistencies for user space resulting in application crashes.

   - plug a race in the vdso32 code between fork and sysctl which causes
     inconsistencies for user space resulting in application crashes.

   - make MPX signal delivery work in compat mode

   - make the dmesg output of traps and faults readable again"

      irq/affinity: Fix extra vecs calculation · 3412386b
      Keith Busch authored 
      This fixes a math error calculating the extra_vecs. The error assumed
only 1 cpu per vector, but the value needs to account for the actual
number of cpus per vector in order to get the correct remainder for
extra CPU assignment.

      Current codes invoke wrongly nf_ct_netns_get in the destroy routine,
it should use nf_ct_netns_put, not nf_ct_netns_get.
It could cause some modules could not be unloaded.

      Merge branch 'netlink_ext_ACK' · ce071832
      David S. Miller authored 
      Johannes Berg says:

====================
netlink extended ACK reporting

Changes since v4:
 * use __NLMSGERR_ATTR_MAX instead of NUM_NLMSGERR_ATTRS

Changes since v3:
 * Add NLM_F_CAPPED and NLM_F_ACK_TLVS flags, to allow entirely
   stateless parsing of the ACK messages by looking at the new
   flags. Need to check NLM_F_ACK_TLVS first, since capping can
   be done in kernels before this patchset without setting the
   flag.
 * Remove "missing_attr" functionality - this can obviously be
   added back rather easily, but I'd rather have more discussion
   about the nesting problem there.
 * Improve documentation of NLMSGERR_ATTR_OFFS
 * Improve message structure documentation, documenting that the
   request message is always capped for success cases
 * fix nlmsg_len of the outer message by calling nlmsg_end()
 * fix memcpy() of the request in success cases, going back to
   the original code that I'd changed before due to the payload
   adjustments that I reverted when introducing tlvlen

Changes since v2:
 * add NUM_NLMSGERR_ATTRS, NLMSGERR_ATTR_MAX
 * fix cookie length to 20 (sha-1 length)
 * move struct members for cookie to patch 3 where they should be
 * another cleanup suggested by David Ahern

Changes since v1:
 * credit Pablo and Jamal
 * incorporate suggestion from David Ahern
 * fix compilation in decnet

      netlink: pass extended ACK struct where available · fe52145f

      netlink: pass extended ACK struct to parsing functions · fceb6435
      Johannes Berg authored 
      Pass the new extended ACK reporting struct to all of the generic
netlink parsing functions. For now, pass NULL in almost all callers
(except for some in the core.)
