      ====================
      strp: Stream parser for messages
      
      This patch set introduces a utility for parsing application layer
      protocol messages in a TCP stream. This is a generalization of the
      mechanism implemented of Kernel Connection Multiplexor.
      
      This patch set adapts KCM to use the strparser. We expect that kTLS
      can use this mechanism also. RDS would probably be another candidate
      to use a common stream parsing mechanism.
      
      The API includes a context structure, a set of callbacks, utility
      functions, and a data ready function. The callbacks include
      a parse_msg function that is called to perform parsing (e.g.
      BPF parsing in case of KCM), and a rcv_msg function that is called
      when a full message has been completed.
      
      For strparser we specify the return codes from the parser to allow
      the backend to indicate that control of the socket should be
      transferred back to userspace to handle some exceptions in the
      stream: The return values are:
      
            >0 : indicates length of successfully parsed message
             0  : indicates more data must be received to parse the message
             -ESTRPIPE : current message should not be processed by the
                kernel, return control of the socket to userspace which
                can proceed to read the messages itself
             other < 0 : Error is parsing, give control back to userspace
                assuming that synchronization is lost and the stream
                is unrecoverable (application expected to close TCP socket)
      
      There is one issue I haven't been able to fully resolve. If parse_msg
      returns ESTRPIPE (wants control back to userspace) the parser may
      already have consumed some bytes of the message. There is no way to
      put bytes back into the TCP receive queue and tcp_read_sock does not
      allow an easy way to peek messages. In lieu of a better solution, we
      return ENODATA on the socket to indicate that the data stream is
      unrecoverable (application needs to close socket). This condition
      should only happen if an application layer message header is split
      across two skbuffs and parsing just the first skbuff wasn't sufficient
      to determine the that transfer to userspace is needed.
      
      This patch set contains:
      
        - strparser implementation
        - changes to kcm to use strparser
        - strparser.txt documentation
      
      v2:
        - Add copyright notice to C files
        - Remove GPL module license from strparser.c
        - Add report of rxpause
      
      v3:
        - Restore GPL module license
        - Use EXPORT_SYMBOL_GPL
      
      v4:
        - Removed unused function, changed another to be static as suggested
          by davem
        - Rewoked data_ready to be called from upper layer, no longer requires
          taking over socket data_ready callback as suggested by Lance Chao
      
      Tested:
        - Ran a KCM thrash test for 24 hours. No behavioral or performance
          differences observed.
