APAR status

  • Closed as program error.

Error description

  • When soreceive is called, the 2nd argument is a pointer
    to an address which should be filled in with the source
    address of the packet.  The symptom is the address is now
    filled in with a part of the data from the packet.
    
    One symptom is SNA Enterprise Extender (EE) links fail to
    activate.
    

Local fix

Problem summary

  • When a customer uses soreceive( ) in their own kernel extension
    to receive UDP data and Source IP address, soreceive() returns
    invalid source IP address. This causes UDP communication
    failure.  The failure would be seen only in limited AIX
    releases.
    

Problem conclusion

  • Code is modified to return correct source IP address when
    soreceive is called to read the UDP data and source IP address.
