      r8169: call netif_napi_del at errpaths and at driver unload · ad1be8d3
      Devendra Naga authored
      when register_netdev fails, the init'ed NAPIs by netif_napi_add must be
      deleted with netif_napi_del, and also when driver unloads, it should
      delete the NAPI before unregistering netdevice using unregister_netdev.

      tcp: reflect SYN queue_mapping into SYNACK packets · fff32699
      Eric Dumazet authored
      While testing how linux behaves on SYNFLOOD attack on multiqueue device
      (ixgbe), I found that SYNACK messages were dropped at Qdisc level
      because we send them all on a single queue.
      
      Obvious choice is to reflect incoming SYN packet @queue_mapping to
      SYNACK packet.
      
      Under stress, my machine could only send 25.000 SYNACK per second (for
      200.000 incoming SYN per second). NIC : ixgbe with 16 rx/tx queues.
      
      After patch, not a single SYNACK is dropped.

      tcp: do not create inetpeer on SYNACK message · 7433819a
      Eric Dumazet authored
      Another problem on SYNFLOOD/DDOS attack is the inetpeer cache getting
      larger and larger, using lots of memory and cpu time.

      8139cp/8139too: terminate the eeprom access with the right opmode · 0bc777bc
      Jason Wang authored
      Currently, we terminate the eeprom access through clearing the CS by:
      
      RTL_W8 (Cfg9346, ~EE_CS); or writeb (~EE_CS, ee_addr);
      
      This would left the eeprom into "Config. Register Write Enable:"
      state which is not expcted as the highest two bits were set to
      0x11 ( expected is the "Normal" mode (0x00)). Solving this by write
      0x0 instead of ~EE_CS when terminating the eeprom access.

      cipso: handle CIPSO options correctly when NetLabel is disabled · 20e2a864
      Paul Moore authored
      When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system
      receives a CIPSO tagged packet it is dropped (cipso_v4_validate()
      returns non-zero).  In most cases this is the correct and desired
      behavior, however, in the case where we are simply forwarding the
      traffic, e.g. acting as a network bridge, this becomes a problem.
      
      This patch fixes the forwarding problem by providing the basic CIPSO
      validation code directly in ip_options_compile() without the need for
      the NetLabel or CIPSO code.  The new validation code can not perform
      any of the CIPSO option label/value verification that
      cipso_v4_validate() does, but it can verify the basic CIPSO option
      format.
      
      The behavior when NetLabel is enabled is unchanged.

      net/mlx4_en: Fix improper use of "port" parameter in mlx4_en_event · 13bf58b7
      Jack Morgenstein authored
      Port is used as an array index before we know if that is proper.
      
      For example, in the catas event case, port is zero; however,
      the port index should lie in the range (1..2).
      
      Fix this by using 'port' only in the events where it is of interest.
      
      Test for port out of range in the default (unhandled event) case,
      and do not output a message if it is not an ethernet port.

      net/mlx4_core: Fix number of EQs used in ICM initialisation · 3fc929e2
      Marcel Apfelbaum authored
      In SRIOV mode, the number of EQs used when computing the total ICM size
      was incorrect.
      
      To fix this, we do the following:
      1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA
         capabilities.  The PPF uses the phys capabilities when it computes things
         like ICM size.
      
         The dev_caps structure will then contain the paravirtualized values, making
         bookkeeping much easier in SRIOV mode. We add a structure rather than a
         single parameter because there will be other fields in the phys_caps.
      
         The first field we add to the mlx4_phys_caps structure is num_phys_eqs.
      
      2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter
         passed to the FW is the number of EQs per VF/PF; each function (PF or VF)
         has this number of EQs available.
      
         However, the total number of EQs which must be allowed for in the ICM is
         (1 << log_num_eqs) * (#VFs + #PFs).  Rather than compute this quantity,
         we allocate ICM space for 1024 EQs (which is the device maximum
         number of EQs, and which is the value we place in the mlx4_phys_caps structure).
      
         For INIT_HCA, however, we use the per-function number of EQs as described
         above.

        I've thrown it through basic testing locally as well, works fine.  The
        one contentious part is the patch that Greg complained about (sysfs
        file with multiple values, should be a debugfs file), which is
        perfectly valid, but not a regression from what the file contains now.
        That will be fixed up separately."

      Pull Sparc updates from David S. Miller:
      
       1) Remove the idiotic situation wherein Leon was a special case in all
          of the TLB/cache handling code.
      
          The worst side effect of this bogosity is that you couldn't build a
          kernel with Leon support enabled (to get better build coverage), and
          test boot it on a non-LEON cpu.
      
          Leon is, in all core respects, programatically identical to the
          32-bit SRMMU.  Except that they put the TLB registers in a different
          alternate address space location.
      
          Through code patching (for fast paths) and run time checks, this
          issue is now a thing of the past.
      
          From Sam Ravnborg.
      
       2) There was a mis-merge of arch/sparc/Kconfig for one of the
          clockevents changes that went in, causing 32-bit sparc to start
          failing to build.
      
          I merged in your tree to get those clockevents changes (and added a
          note to the merge commit) then added Stephen Rothwell's fix for the
          merge error.
      
       3) Software quad floating point emulation was not working properly on
          more recent Niagara chips, because the way the situation is reported
          by the cpu has changed.
      
          Nobody noticed because gcc emits calls to software emulation
          routines in glibc.

      BUG: soft lockup - CPU#3 stuck for 22s ! [mountall.1603]
      
      Fix this by making create_task_io_context() returns -EBUSY in this case
