      tcp: len check is unnecessarily devastating, change to WARN_ON · 2fceec13
      Ilpo Järvinen 提交于
      All callers are prepared for alloc failures anyway, so this error
      can safely be boomeranged to the callers domain without super
      bad consequences. ...At worst the connection might go into a state
      where each RTO tries to (unsuccessfully) re-fragment with such
      a mis-sized value and eventually dies.

      sctp: malloc enough room for asconf-ack chunk · 2cab86be
      Wei Yongjun 提交于
      Sometime the ASCONF_ACK parameters can equal to the fourfold of
      ASCONF parameters, this only happend in some special case:
      
        ASCONF parameter is :
          Unrecognized Parameter (4 bytes)
        ASCONF_ACK parameter should be:
          Error Cause Indication parameter (8 bytes header)
           + Error Cause (4 bytes header)
             + Unrecognized Parameter (4bytes)
      
      Four 4bytes Unrecognized Parameters in ASCONF chunk will cause panic.

      net: Fix dev dev_ethtool_get_rx_csum() for forced NETIF_F_RXCSUM · 4dd5ffe4
      Michał Mirosław 提交于
      dev_ethtool_get_rx_csum() won't report rx checksumming when it's not
      changeable and driver is converted to hw_features and friends. Fix this.
      
      (dev->hw_features & NETIF_F_RXCSUM) check is dropped - if the
      ethtool_ops->get_rx_csum is set, then driver is not coverted, yet.

      usbnet: use eth%d name for known ethernet devices · c261344d
      Arnd Bergmann 提交于
      The documentation for the USB ethernet devices suggests that
      only some devices are supposed to use usb0 as the network interface
      name instead of eth0. The logic used there, and documented in
      Kconfig for CDC is that eth0 will be used when the mac address
      is a globally assigned one, but usb0 is used for the locally
      managed range that is typically used on point-to-point links.
      
      Unfortunately, this has caused a lot of pain on the smsc95xx
      device that is used on the popular pandaboard without an
      EEPROM to store the MAC address, which causes the driver to
      call random_ether_address().
      
      Obviously, there should be a proper MAC addressed assigned to
      the device, and discussions are ongoing about how to solve
      this, but this patch at least makes sure that the default
      interface naming gets a little saner and matches what the
      user can expect based on the documentation, including for
      new devices.
      
      The approach taken here is to flag whether a device might be a
      point-to-point link with the new FLAG_POINTTOPOINT setting in
      the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT
      and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one
      of the two.  The usbnet framework only looks at the MAC address
      for device naming if both flags are set, otherwise it trusts the
      flag.
