      gianfar: Don't reset TBI<->SerDes link if it's already up · bdb59f94
      Trent Piepho 提交于
      The link may be up already via the chip's reset strapping, or though action
      of U-Boot, or from the last time the interface was brought up.  Resetting
      the link causes it to go down for several seconds.  This can significantly
      increase the time from power-on to DHCP completion and a device being
      accessible to the network.

      gianfar: Fix race in TBI/SerDes configuration · c132419e
      Trent Piepho 提交于
      The init_phy() function attaches to the PHY, then configures the
      SerDes<->TBI link (in SGMII mode).  The TBI is on the MDIO bus with the PHY
      (sort of) and is accessed via the gianfar's MDIO registers, using the
      functions gfar_local_mdio_read/write(), which don't do any locking.
      
      The previously attached PHY will start a work-queue on a timer, and
      probably an irq handler as well, which will talk to the PHY and thus use
      the MDIO bus.  This uses phy_read/write(), which have locking, but not
      against the gfar_local_mdio versions.
      
      The result is that PHY code will try to use the MDIO bus at the same time
      as the SerDes setup code, corrupting the transfers.
      
      Setting up the SerDes before attaching to the PHY will insure that there is
      no race between the SerDes code and *our* PHY, but doesn't fix everything.
      Typically the PHYs for all gianfar devices are on the same MDIO bus, which
      is associated with the first gianfar device.  This means that the first
      gianfar's SerDes code could corrupt the MDIO transfers for a different
      gianfar's PHY.
      
      The lock used by phy_read/write() is contained in the mii_bus structure,
      which is pointed to by the PHY.  This is difficult to access from the
      gianfar drivers, as there is no link between a gianfar device and the
      mii_bus which shares the same MDIO registers.  As far as the device layer
      and drivers are concerned they are two unrelated devices (which happen to
      share registers).
      
      Generally all gianfar devices' PHYs will be on the bus associated with the
      first gianfar.  But this might not be the case, so simply locking the
      gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup
      code is going to use.
      
      We solve this by having the code that creates the gianfar platform device
      look in the device tree for an mdio device that shares the gianfar's
      registers.  If one is found the ID of its platform device is saved in the
      gianfar's platform data.
      
      A new function in the gianfar mii code, gfar_get_miibus(), can use the bus
      ID to search through the platform devices for a gianfar_mdio device with
      the right ID.  The platform device's driver data is the mii_bus structure,
      which the SerDes setup code can use to lock the current bus.

      bonding: fix panic when taking bond interface down before removing module · ce39a800
      Andy Gospodarek 提交于
      A panic was discovered with bonding when using mode 5 or 6 and trying to
      remove the slaves from the bond after the interface was taken down.
      When calling 'ifconfig bond0 down' the following happens:
      
          bond_close()
              bond_alb_deinitialize()
                  tlb_deinitialize()
      		kfree(bond_info->tx_hashtbl)
                      bond_info->tx_hashtbl = NULL
      
      Unfortunately if there are still slaves in the bond, when removing the
      module the following happens:
      
          bonding_exit()
              bond_free_all()
                  bond_release_all()
                      bond_alb_deinit_slave()
                          tlb_clear_slave()
                              tx_hash_table = BOND_ALB_INFO(bond).tx_hashtbl
      			u32 next_index = tx_hash_table[index].next
      
      As you might guess we panic when trying to access a few entries into the
      table that no longer exists.
      
      I experimented with several options (like moving the calls to
      tlb_deinitialize somewhere else), but it really makes the most sense to
      be part of the bond_close routine.  It also didn't seem logical move
      tlb_clear_slave around too much, so the simplest option seems to add a
      check in tlb_clear_slave to make sure we haven't already wiped the
      tx_hashtbl away before searching for all the non-existent hash-table
      entries that used to point to the slave as the output interface.

      bonding: Clean up resource leaks · a434e43f
      Jay Vosburgh 提交于
      This patch reworks the resource free logic performed at the time
      a bonding device is released.  This (a) closes two resource leaks, one
      for workqueues and one for multicast lists, and (b) improves commonality
      of code between the "destroy one" and "destroy all" paths by performing
      final free activity via destructor instead of explicitly (and differently)
      in each path.
