      bonding: avoid NETDEV_CHANGEMTU event when unregistering slave · f51048c3
      WANG Cong authored
      As Hongjun/Nicolas summarized in their original patch:
      
      "
      When a device changes from one netns to another, it's first unregistered,
      then the netns reference is updated and the dev is registered in the new
      netns. Thus, when a slave moves to another netns, it is first
      unregistered. This triggers a NETDEV_UNREGISTER event which is caught by
      the bonding driver. The driver calls bond_release(), which calls
      dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in
      the old netns).
      "
      
      This is a very special case, because the device is being unregistered
      no one should still care about the NETDEV_CHANGEMTU event triggered
      at this point, we can avoid broadcasting this event on this path,
      and avoid touching inetdev_event()/addrconf_notify() path.
      
      It requires to export __dev_set_mtu() to bonding driver.

      Following up on the discussion at
        https://www.spinics.net/lists/netdev/msg442859.html
      - make rds_tcp_accept_one() call sock_create_lite()
      - add a WARN_ON() to sock_graft()
      
      Tested by running an infinite while() loop that does
      (module-load; rds-stress; module-unload) and monitors
      TCP slabinfo while the test is running.

      net/sock: add WARN_ON(parent->sk) in sock_graft() · 0ffdaf5b
      Sowmini Varadhan authored
      sock_graft() unilaterally sets up parent->sk based on the
      assumption that the existing parent->sk is null. If this
      condition is not true, then the existing parent->sk would
      be leaked, so add a WARN_ON() to alert callers who may fall
      in this category.

      rds: tcp: use sock_create_lite() to create the accept socket · 0933a578
      Sowmini Varadhan authored
      There are two problems with calling sock_create_kern() from
      rds_tcp_accept_one()
      1. it sets up a new_sock->sk that is wasteful, because this ->sk
         is going to get replaced by inet_accept() in the subsequent ->accept()
      2. The new_sock->sk is a leaked reference in sock_graft() which
         expects to find a null parent->sk
      
      Avoid these problems by calling sock_create_lite().

      vishnuvardhan authored
      As per the SAMA5D3 device specification it supports Jumbo frames.
      But the suggested flag and length of bytes it supports was not updated
      in this driver config_structure.
      The maximum jumbo frames the device supports :
      10240 bytes as per the device spec.
      
      While changing the MTU value greater than 1500, it threw error:
      sudo ifconfig eth1 mtu 9000
      SIOCSIFMTU: Invalid argument
      
      Add this support to driver so that it works as expected and designed.
