      openvswitch: fix panic with multiple vlan headers · 2ba5af42
      Jiri Benc authored
      When there are multiple vlan headers present in a received frame, the first
      one is put into vlan_tci and protocol is set to ETH_P_8021Q. Anything in the
      skb beyond the VLAN TPID may be still non-linear, including the inner TCI
      and ethertype. While ovs_flow_extract takes care of IP and IPv6 headers, it
      does nothing with ETH_P_8021Q. Later, if OVS_ACTION_ATTR_POP_VLAN is
      executed, __pop_vlan_tci pulls the next vlan header into vlan_tci.
      
      This leads to two things:
      
      1. Part of the resulting ethernet header is in the non-linear part of the
         skb. When eth_type_trans is called later as the result of
         OVS_ACTION_ATTR_OUTPUT, kernel BUGs in __skb_pull. Also, __pop_vlan_tci
         is in fact accessing random data when it reads past the TPID.
      
      2. network_header points into the ethernet header instead of behind it.
         mac_len is set to a wrong value (10), too.

      net: ipv6: fib: don't sleep inside atomic lock · 793c3b40

      The function fib6_commit_metrics() allocates a piece of memory in mode
      GFP_KERNEL while holding an atomic lock from higher up in the stack, in
      the function __ip6_ins_rt(). This produces the following BUG:

      net: fec: ptp: avoid register access when ipg clock is disabled · 91c0d987
      Nimrod Andy authored
      The current kernel hang on i.MX6SX with rootfs mount from MMC.
      The root cause is that ptp uses a periodic timer to access enet register
      even if ipg clock is disabled.
      
      FEC ptp driver start one period timer to read 1588 counter register in the
      ptp init function that is called after FEC driver is probed.
      
      To save power, after FEC probe finish, FEC driver disable all clocks including
      ipg clock that is needed for register access.
      
      i.MX5x, i.MX6q/dl/sl FEC register access don't cause system hang when ipg clock
      is disabled, just return zero value. But for i.MX6sx SOC, it cause system hang.
      
      To avoid the issue, we need to check ptp clock status before ptp timer count access.

      The first patch is from Mirza Krak, it fixes the initialization of the hardware
      in the sja1000 driver. The next patch is contributed by Dan Carpenter, it fixes
      the error handling in the c_can's probe function. Then there are two patches
      for the flexcan driver, one by Alexander Stein, which fixes the resetting of
      the bus error interrupt mask, the other one by Sebastian Andrzej Siewior which
      adds an additional error state transition message.

      cxgb4: Fix race condition in cleanup · 29aaee65
      Anish Bhatt authored
      There is a possible race condition when we unregister the PCI Driver and then
      flush/destroy the global "workq". This could lead to situations where there
      are tasks on the Work Queue with references to now deleted adapter data
      structures. Instead, have per-adapter Work Queues which were instantiated and
      torn down in init_one() and remove_one(), respectively.

      sctp: not send SCTP_PEER_ADDR_CHANGE notifications with failed probe · 061079ac
      zhuyj authored
      Since the transport has always been in state SCTP_UNCONFIRMED, it
      therefore wasn't active before and hasn't been used before, and it
      always has been, so it is unnecessary to bug the user with a
      notification.

      bnx2x: Revert UNDI flushing mechanism · 7c3afd85
      Yuval Mintz authored
      Commit 91ebb929 ("bnx2x: Add support for Multi-Function UNDI") [which was
      later supposedly fixed by de682941 ("bnx2x: Fix UNDI driver unload")]
      introduced a bug in which in some [yet-to-be-determined] scenarios the
      alternative flushing mechanism which was to guarantee the Rx buffers are
      empty before resetting them during device probe will fail.
      If this happens, when device will be loaded once more a fatal attention will
      occur; Since this most likely happens in boot from SAN scenarios, the machine
      will fail to load.
      
      Notice this may occur not only in the 'Multi-Function' scenario but in the
      regular scenario as well, i.e., this introduced a regression in the driver's
      ability to perform boot from SAN.
      
      The patch reverts the mechanism and applies the old scheme to multi-function
      devices as well as to single-function devices.

      i40e: Fix for recent kernel panic · 478c9e74
      Anjali Singhai Jain authored
      Whenever we get a Tx hang we issue a PFR, which means we send AQ
      messages to VFS about the reset coming. Unfortunately with the recent
      fix to be able to send messages to all VFS which earlier was not
      happening at all we now are sending messages to not just the VFS that
      are up but also to VFS that are not up.  AQ complains about this and
      sends us an error in ARQ called LAN overflow event for a queue. We
      check if the queue belongs to a VF and if it does we try to send a
      vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled
      we will be entering this function with a non-active VF id. In this
      function we were assuming VF struct is populated but it won't be if
      the VF is not active.

       "These are a couple of regression fixes, cpuidle menu governor
        optimizations, fixes for ACPI proccessor and battery drivers,
        hibernation fix to avoid problems related to the e820 memory map,
        fixes for a few cpufreq drivers and a new version of the suspend
        profiling tool analyze_suspend.py.
      
        Specifics:
      
         - Fix for an ACPI-based device hotplug regression introduced in 3.14
           that causes a kernel panic to trigger when memory hot-remove is
           attempted with CONFIG_ACPI_HOTPLUG_MEMORY unset from Tang Chen
      
         - Fix for a cpufreq regression introduced in 3.16 that triggers a
           "sleeping function called from invalid context" bug in
           dev_pm_opp_init_cpufreq_table() from Stephen Boyd
      
         - ACPI battery driver fix for a warning message added in 3.16 that
           prints silly stuff sometimes from Mariusz Ceier
      
         - Hibernation fix for safer handling of mismatches in the 820 memory
           map between the configurations during image creation and during the
           subsequent restore from Chun-Yi Lee
      
         - ACPI processor driver fix to handle CPU hotplug notifications
           correctly during system suspend/resume from Lan Tianyu
      
         - Series of four cpuidle menu governor cleanups that also should
           speed it up a bit from Mel Gorman
      
         - Fixes for the speedstep-smi, integrator, cpu0 and arm_big_little
           cpufreq drivers from Hans Wennborg, Himangi Saraogi, Markus
           Pargmann and Uwe Kleine-König
      
         - Version 3.0 of the analyze_suspend.py suspend profiling tool from
           Todd E Brandt"

       "Part two of the PCI changes for v3.17:
      
          - Remove DEFINE_PCI_DEVICE_TABLE macro use (Benoit Taine)
      
        It's a mechanical change that removes uses of the
        DEFINE_PCI_DEVICE_TABLE macro.  I waited until later in the merge
        window to reduce conflicts, but it's possible you'll still see a few"
