Problem summary

  • APAR NUMBER:  PJ41115
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  TCP/IP NATIVE STACK
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    With TCP/IP socket trace enabled, the gethostid() API may
    corrupt the socket block header.
    
    COMMENTS:
    The gethostid() API within segment ctsj.asm does not take in a
    socket descriptor. In processing the gethostid() API, the code
    within ctsj.asm attempts to write socket trace information into
    the socket block entry. However, since gethostid() does not
    take in a socket descriptor, Register 4 is never set up and
    still points to the socket block header that was used to obtain
    the socket block lock. This causes the corruption of the socket
    block header when the gethostid() API is issued and TCP/IP
    socket trace is enabled.
    

Problem conclusion

  • SOLUTION:
    Segment ctsj.asm has been updated properly initialize register
    4 during gethostid() processing, and to check in the dotrace()
    function for whether Register 4 contains a valid socket block
    address before attempting to write trace information into the
    socket block entry.
