      tcp: len check is unnecessarily devastating, change to WARN_ON · 2fceec13
      Ilpo Järvinen authored
      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 authored
      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.
