A method of and system for encrypting and decrypting data on a computer system is disclosed. In one embodiment, the system comprises an encrypting operating system (EOS), which is a modified UNIX operating system. The EOS is configured to use a symmetric encryption algorithm and an encryption key to encrypt data transferred from physical memory to secondary devices, such as disks, swap devices, network file systems, network buffers, pseudo file systems, or any other structures external to the physical memory and on which can data can be stored. The EOS further uses the symmetric encryption algorithm and the encryption key to decrypt data transferred from the secondary devices back to physical memory. In other embodiments, the EOS adds an extra layer of security by also encrypting the directory structure used to locate the encrypted data. In a further embodiment a user or process is authenticated and its credentials checked before a file can be accessed, using a key management facility that controls access to one or more keys for encrypting and decrypting data.

An operating system directed to using special properties of a common inter-process communications mechanism (IPC), namely UNIX domain socket-pairs or stream-pipes alternatively as a storage medium for file-descriptors of UNIX processes. When a file-descriptor is written into a socket-pair, and closed in the UNIX process, the file remains open, but occupies no space in the process' file-table. The file-descriptor may later be read out of the socket-pair to reestablish it in the file-table, and access it. This property is implemented in an IPC mechanism of UNIX operating system whereby a process such as a dispatcher may manage more connections and processes than its file-table size allow. This provides scalability improvements of the UNIX operating system.

A method and apparatus for controlling the termination of one or more processes in an information handling system, such as UNIX processes running under the control of an UNIX operating system kernel, in response to a shutdown command. Processes may optionally register with a registration facility of the operating system kernel as permanent processes ineligible for process termination or as blocking processes entitled to advance notification of process termination. In response to receiving a shutdown command, a shutdown facility of the operating system kernel notifies each process that has registered as a blocking process of an impending shutdown. Upon the expiration of a predetermined time interval, the shutdown facility determines whether all of the processes that have registered as blocking processes have concurred in the shutdown, either by unregistering as blocking processes or by terminating. If all of the processes that have registered as blocking processes have concurred in the shutdown, the shutdown facility terminates processes that have not registered as permanent processes while allowing processes that have registered as permanent processes to continue to run. Otherwise, the shutdown facility aborts the shutdown without terminating any of the processes and generates a message identifying processes that have not concurred in the shutdown.
