      drivers: net: cpsw: remove cpsw_ale_stop from cpsw_ale_destroy · 4484d052
      Mugunthan V N authored
      when cpsw is build as modulea and simple insert and removal of module
      creates a deadlock, due to delete timer. the timer is created and destroyed
      in cpsw_ale_start and cpsw_ale_stop which are from device open and close.

      net: mv643xx_eth: reclaim TX skbs only when released by the HW · 2c2a9cbd
      Karl Beldan authored
      ATM, txq_reclaim will dequeue and free an skb for each tx desc released
      by the hw that has TX_LAST_DESC set. However, in case of TSO, each
      hw desc embedding the last part of a segment has TX_LAST_DESC set,
      losing the one-to-one 'last skb frag'/'TX_LAST_DESC set' correspondance,
      which causes data corruption.
      
      Fix this by checking TX_ENABLE_INTERRUPT instead of TX_LAST_DESC, and
      warn when trying to dequeue from an empty txq (which can be symptomatic
      of releasing skbs prematurely).

      nodes and serves as preparatory patch for the fix.

      Kept a WARN_ON as this problem indicates a broken or misconfigured NIC.

      a ndo_init function to keep the configured setting.

      macvtap: Fix csum_start when VLAN tags are present · 3ce9b20f
      Herbert Xu authored
      When VLAN is in use in macvtap_put_user, we end up setting
      csum_start to the wrong place.  The result is that the whoever
      ends up doing the checksum setting will corrupt the packet instead
      of writing the checksum to the expected location, usually this
      means writing the checksum with an offset of -4.
      
      This patch fixes this by adjusting csum_start when VLAN tags are
      detected.

      The root cause is that eth1 is not opened and clock is not enabled, and .suspend() still
      call .fec_enet_clk_enable() to disable clock.
      
      To avoid the broken, let it check network device up status by calling .netif_running()
      before disable/enable clocks.

      ====================
      tun: Fix csum_start and TUN_PKT_STRIP
      
      The first patch fixes a serious problem that breaks checksum offload
      in VMs while the second patch fixes a problem that probably affects
      no one.

      tun: Fix TUN_PKT_STRIP setting · 2eb783c4
      Herbert Xu authored
      We set the flag TUN_PKT_STRIP if the user buffer provided is too
      small to contain the entire packet plus meta-data.  However, this
      has been broken ever since we added GSO meta-data.  VLAN acceleration
      also has the same problem.
      
      This patch fixes this by taking both into account when setting the
      TUN_PKT_STRIP flag.
      
      The fact that this has been broken for six years without anyone
      realising means that nobody actually uses this flag.

      tun: Fix csum_start with VLAN acceleration · a8f9bfdf
      Herbert Xu authored
      When VLAN acceleration is in use on the xmit path, we end up
      setting csum_start to the wrong place.  The result is that the
      whoever ends up doing the checksum setting will corrupt the packet
      instead of writing the checksum to the expected location, usually
      this means writing the checksum with an offset of -4.
      
      This patch fixes this by adjusting csum_start when VLAN acceleration
      is detected.

      uapi: add missing network related headers to kbuild · 7071cf7f
      stephen hemminger authored
      The makefile for sanitizing kernel headers uses the kbuild file
      to determine which files to do. Several networking related headers
      were missing. Without these headers iproute2 build would break.
