ABSTRACT:
Mechanisms for preventing IP spoofing and facilitating parsing of private data areas in system and network connection requests are provided. With these mechanisms, an identifier, such as the high order bit of a Q_Key, is utilized to determine if a communication connection request originates with a privileged process. A second identifier is used to specify whether a private data area of a communication connection request utilizes predefined fields of a predefined structure or format. Only when the first identifier specifies that the request originates from a privileged process is the processing of the request permitted to be performed. Based on the setting of the second identifier, specific information is retrieved from the predefined fields of the private data area for use in establishing the requested communication connection.
