APAR status

  • Closed as program error.

Error description

  • Enabling tcp_fastlo will show tcp/ip packets with a wrong
    packet lenght in iptrace/ipreport.
    These tcp_fastlo packets will have a fake TCP/IP header
    anyway, but due to ip_len=40 we can't see any payload
    bytes
    with ipreport.
    

Local fix

Problem summary

  • When fastlo is enabled, iptrace is unable to capture
    packet pay load
    

Problem conclusion

  • Correct the code to capture packet pay load when fastlo enabled
    

Temporary fix
