Error description

  • The UDPTERM records (SMF type 119 subtype 10) do not have the
    SMF119UD_UCRIP or SMF119UD_UCRPort values set (all 0s) in some
    conditions, even though packets have flowed in both directions.
    This is a fix completion for PM68039, which did not address
    the problem for Fast UDP sockets.

    ****************************************************************
    The SMFCONFIG TYPE119 UDPTERM profile setting creates an SMF
    type 119 subtype 10 record to be written when a UDP socket is
    closed.  The SMF119UD_UCRIP field is supposed to contain the
    remote IP address of the last datagram received.  The
    SMF119UD_UCRPORT field is supposed to contain the remote port
    of the last datagram received.  These values are not being
    set for UDP Fast Local Sockets.

Problem conclusion

  • Routine EZBUDLCL (UDP Fast Local Socket Routine) within macro
    TOUUWP has been amended to load the socket address from the
    source UCB into umispdsa and umispdsa6 for IPv4 and IPv6
    sockets, respectively. The associated port value will also be
    loaded into umispdsp, and umisptype will be set accordingly.
    This will all be done upon return from the appropriate
    ?SLP_FIND_POLICY invocation.
    
    Loading these values in the data path will make them available
    for subsequent SMF 119 reporting by EZBUDSMF.  The values will
    appear in the fields SMF119UD_UCRIP/SMF119UD_UCRPORT (i.e.,
    remote IP address/port of the last datagram received on the
    socket).
