      net: convert unicast addr list · ccffad25
      Jiri Pirko 提交于
      This patch converts unicast address list to standard list_head using
      previously introduced struct netdev_hw_addr. It also relaxes the
      locking. Original spinlock (still used for multicast addresses) is not
      needed and is no longer used for a protection of this list. All
      reading and writing takes place under rtnl (with no changes).
      
      I also removed a possibility to specify the length of the address
      while adding or deleting unicast address. It's always dev->addr_len.
      
      The convertion touched especially e1000 and ixgbe codes when the
      change is not so trivial.

      net: release dst entry in dev_hard_start_xmit() · 93f154b5
      Eric Dumazet 提交于
      One point of contention in high network loads is the dst_release() performed
      when a transmited skb is freed. This is because NIC tx completion calls
      dev_kree_skb() long after original call to dev_queue_xmit(skb).
      
      CPU cache is cold and the atomic op in dst_release() stalls. On SMP, this is
      quite visible if one CPU is 100% handling softirqs for a network device,
      since dst_clone() is done by other cpus, involving cache line ping pongs.
      
      It seems right place to release dst is in dev_hard_start_xmit(), for most
      devices but ones that are virtual, and some exceptions.
      
      David Miller suggested to define a new device flag, set in alloc_netdev_mq()
      (so that most devices set it at init time), and carefuly unset in devices
      which dont want a NULL skb->dst in their ndo_start_xmit().
      
      List of devices that must clear this flag is :
      
      - loopback device, because it calls netif_rx() and quoting Patrick :
          "ip_route_input() doesn't accept loopback addresses, so loopback packets
           already need to have a dst_entry attached."
      - appletalk/ipddp.c : needs skb->dst in its xmit function
      
      - And all devices that call again dev_queue_xmit() from their xmit function
      (as some classifiers need skb->dst) : bonding, vlan, macvlan, eql, ifb, hdlc_fr

      netdev: Allocate multiple queues for TX. · e8a0464c
      David S. Miller 提交于
      alloc_netdev_mq() now allocates an array of netdev_queue
      structures for TX, based upon the queue_count argument.
      
      Furthermore, all accesses to the TX queues are now vectored
      through the netdev_get_tx_queue() and netdev_for_each_tx_queue()
      interfaces.  This makes it easy to grep the tree for all
      things that want to get to a TX queue of a net device.
      
      Problem spots which are not really multiqueue aware yet, and
      only work with one queue, can easily be spotted by grepping
      for all netdev_get_tx_queue() calls that pass in a zero index.

      macvlan: Fix memleak on device removal/crash on module removal · 73120964
      Patrick McHardy 提交于
      As noticed by Ben Greear, macvlan crashes the kernel when unloading the
      module. The reason is that it tries to clean up the macvlan_port pointer
      on the macvlan device itself instead of the underlying device. A non-NULL
      pointer is taken as indication that the macvlan_handle_frame_hook is
      valid, when receiving the next packet on the underlying device it tries
      to call the NULL hook and crashes.
      
      Clean up the macvlan_port on the correct device to fix this.

      [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctls · 88d3aafd
      Jeff Garzik 提交于
      For the operations
      	get-tx-csum
      	get-sg
      	get-tso
      	get-ufo
      the default ethtool_op_xxx behavior is fine for all drivers, so we
      permit op==NULL to imply the default behavior.
      
      This provides a more uniform behavior across all drivers, eliminating
      ethtool(8) "ioctl not supported" errors on older drivers that had
      not been updated for the latest sub-ioctls.
      
      The ethtool_op_xxx() functions are left exported, in case anyone
      wishes to call them directly from a driver-private implementation --
      a not-uncommon case.  Should an ethtool_op_xxx() helper remain unused
      for a while, except by net/core/ethtool.c, we can un-export it at a
      later date.

      [NET]: Make the device list and device lookups per namespace. · 881d966b
      Eric W. Biederman 提交于
      This patch makes most of the generic device layer network
      namespace safe.  This patch makes dev_base_head a
      network namespace variable, and then it picks up
      a few associated variables.  The functions:
      dev_getbyhwaddr
      dev_getfirsthwbytype
      dev_get_by_flags
      dev_get_by_name
      __dev_get_by_name
      dev_get_by_index
      __dev_get_by_index
      dev_ioctl
      dev_ethtool
      dev_load
      wireless_process_ioctl
      
      were modified to take a network namespace argument, and
      deal with it.
      
      vlan_ioctl_set and brioctl_set were modified so their
      hooks will receive a network namespace argument.
      
      So basically anthing in the core of the network stack that was
      affected to by the change of dev_base was modified to handle
      multiple network namespaces.  The rest of the network stack was
      simply modified to explicitly use &init_net the initial network
      namespace.  This can be fixed when those components of the network
      stack are modified to handle multiple network namespaces.
      
      For now the ifindex generator is left global.
      
      Fundametally ifindex numbers are per namespace, or else
      we will have corner case problems with migration when
      we get that far.
      
      At the same time there are assumptions in the network stack
      that the ifindex of a network device won't change.  Making
      the ifindex number global seems a good compromise until
      the network stack can cope with ifindex changes when
      you change namespaces, and the like.
