      net: bonding: Fix transmit load balancing in balance-alb mode · cbf5ecb3
      Kosuke Tatsukawa authored
      balance-alb mode used to have transmit dynamic load balancing feature
      enabled by default.  However, transmit dynamic load balancing no longer
      works in balance-alb after commit 8b426dc5 ("bonding: remove
      hardcoded value").
      
      Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to
      send packets.  This function uses the parameter tlb_dynamic_lb.
      tlb_dynamic_lb used to have the default value of 1 for balance-alb, but
      now the value is set to 0 except in balance-tlb.
      
      Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb
      for balance-alb similar to balance-tlb.

      rds: Make sure updates to cp_send_gen can be observed · e623a48e
      Håkon Bugge authored
      cp->cp_send_gen is treated as a normal variable, although it may be
      used by different threads.
      
      This is fixed by using {READ,WRITE}_ONCE when it is incremented and
      READ_ONCE when it is read outside the {acquire,release}_in_xmit
      protection.
      
      Normative reference from the Linux-Kernel Memory Model:
      
          Loads from and stores to shared (but non-atomic) variables should
          be protected with the READ_ONCE(), WRITE_ONCE(), and
          ACCESS_ONCE().
      
      Clause 5.1.2.4/25 in the C standard is also relevant.

      net: ethernet: ti: cpsw: Push the request_irq function to the end of probe · 070f9c65
      Keerthy authored
      Push the request_irq function to the end of probe so as
      to ensure all the required fields are populated in the event
      of an ISR getting executed right after requesting the irq.
      
      Currently while loading the crash kernel a crash was seen as
      soon as devm_request_threaded_irq was called. This was due to
      n->poll being NULL which is called as part of net_rx_action
      function.

      ipv4: initialize fib_trie prior to register_netdev_notifier call. · 8799a221
      Mahesh Bandewar authored
      Net stack initialization currently initializes fib-trie after the
      first call to netdevice_notifier() call. In fact fib_trie initialization
      needs to happen before first rtnl_register(). It does not cause any problem
      since there are no devices UP at this moment, but trying to bring 'lo'
      UP at initialization would make this assumption wrong and exposes the issue.
      
      Fixes following crash

      rtnetlink: allocate more memory for dev_set_mac_address() · 153711f9
      WANG Cong authored
      virtnet_set_mac_address() interprets mac address as struct
      sockaddr, but upper layer only allocates dev->addr_len
      which is ETH_ALEN + sizeof(sa_family_t) in this case.
      
      We lack a unified definition for mac address, so just fix
      the upper layer, this also allows drivers to interpret it
      to struct sockaddr freely.

      The BCM53125 entry was missing an arl_entries member which would
      basically prevent the ARL search from terminating properly. This switch
      has 4 ARL entries, so add that.
