      Linus Torvalds 提交于
      Pull networking update from David Miller:
      
       1) Pairing and deadlock fixes in bluetooth from Johan Hedberg.
      
       2) Add device IDs for AR3011 and AR3012 bluetooth chips.  From
          Giancarlo Formicuccia and Marek Vasut.
      
       3) Fix wireless regulatory deadlock, from Eliad Peller.
      
       4) Fix full TX ring panic in bnx2x driver, from Eric Dumazet.
      
       5) Revert the two commits that added skb_orphan_try(), it causes
          erratic bonding behavior with UDP clients and the gains it used to
          give are mostly no longer happening due to how BQL works.  From Eric
          Dumazet.
      
       6) It took two tries, but Thomas Graf fixed a problem wherein we
          registered ipv6 routing procfs files before their backend data were
          initialized properly.
      
       7) Fix max GSO size setting in be2net, from Sarveshwar Bandi.
      
       8) PHY device id mask is wrong for KSZ9021 and KS8001 chips, fix from
          Jason Wang.
      
       9) Fix use of stale SKB data pointer after skb_linearize() call in
          batman-adv, from Antonio Quartulli.
      
      10) Fix memory leak in IXGBE due to missing __GFP_COMP, from Alexander
          Duyck.
      
      11) Fix probing of Gobi devices in qmi_wwan usbnet driver, from Bjørn
          Mork.
      
      12) Fix suspend/resume and open failure handling in usbnet from Ming
          Lei.
      
      13) Attempt to fix device r8169 hangs for certain chips, from Francois
          Romieu.
      
      14) Fix advancement of RX dirty pointer in some situations in sh_eth
          driver, from Yoshihiro Shimoda.
      
      15) Attempt to fix restart of IPV6 routing table dumps when there is an
          intervening table update.  From Eric Dumazet.
      
      16) Respect security_inet_conn_request() return value in ipv6 TCP.  From
          Neal Cardwell.
      
      17) Add another iPAD device ID to ipheth driver, from Davide Gerhard.
      
      18) Fix access to freed SKB in l2tp_eth_dev_xmit(), and fix l2tp lockdep
          splats, from Eric Dumazet.
      
      19) Make sure all bridge devices, regardless of whether they were
          created via netlink or ioctls, have their rtnetlink ops hooked up.
          From Thomas Graf and Stephen Hemminger.

      can: flexcan: use be32_to_cpup to handle the value of dt entry · 85f2f834
      Hui Wang 提交于
      The freescale arm i.MX series platform can support this driver, and
      usually the arm cpu works in the little endian mode by default, while
      device tree entry value is stored in big endian format, we should use
      be32_to_cpup() to handle them, after modification, it can work well
      both on the le cpu and be cpu.

      bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2) · 149ddd83
      stephen hemminger 提交于
      This ensures that bridges created with brctl(8) or ioctl(2) directly
      also carry IFLA_LINKINFO when dumped over netlink. This also allows
      to create a bridge with ioctl(2) and delete it with RTM_DELLINK.

      Jens Freimann 提交于
      On some architectures address spaces are set up in a way that this is
      not necessary to work properly but on some others (like s390) it is.
      Make sure we operate on the user address space to allow copy_xxx_user()
      from the vhost_worker() thread by setting it explicitly before calling
      use_mm() and revert it after unuse_mm().

      ixgbe: Do not pad FCoE frames as this can cause issues with FCoE DDP · 57efd44c
      Alexander Duyck 提交于
      FCoE target mode was experiencing issues due to the fact that we were
      sending up data frames that were padded to 60 bytes after the DDP logic had
      already stripped the frame down to 52 or 56 depending on the use of VLANs.
      This was resulting in the FCoE DDP logic having issues since it thought the
      frame still had data in it due to the padding.
      
      To resolve this, adding code so that we do not pad FCoE frames prior to
      handling them to the stack.

      It appears that like most virtual devices, l2tp should be converted to
      LLTX mode.
      
      This patch takes care of statistics using atomic_long in both RX and TX
      paths, and fix a bug in l2tp_eth_dev_recv(), which was caching skb->data
      before a pskb_may_pull() call.

      Revert "mmc: omap_hsmmc: Enable Auto CMD12" · fe852273
      Ming Lei 提交于
      This patch reverts the commit dba3c29e.
      
      After bisecting, this commit dba3c29e is found to ruin micro-SD card data
      (writing incorrect file, or fs is corrupt after several times mount)
      on the beagle-xm revB, and reverting the commit will fix the problem.
      
      Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about
      the Auto CMD12 Enable bit.
              - SDIO does not support this feature.
              - SD card only.
      Looks it is not suitable to always enable Auto CMD12 in host controller
      driver.
      
      Considered that the commit is not mature enough, so ask to revert it
      first.

      mmc: block: fix the data timeout issue with ACMD22 · d380443c
      Subhash Jadavani 提交于
      If multi block write operation fails for SD card, during
      error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22)
      to know how many blocks were already programmed by card.
      
      But mmc_sd_num_wr_blocks() function which sends the ACMD22
      calculates the data timeout value from csd.tacc_ns and
      csd.tacc_clks parameters which will be 0 for block addressed
      (>2GB cards) SD card. This would result in timeout_ns and
      timeout_clks being 0 in the mmc_request passed to host driver.
      This means host controller would program its data timeout timer
      value with 0 which could result in DATA TIMEOUT errors from
      controller.
      
      To fix this issue, mmc_sd_num_wr_blocks() should instead
      just call the mmc_set_data_timeout() to calculate the
      data timeout value. mmc_set_data_timeout() function
      ensures that non zero timeout value is set even for
      block addressed SD cards.
