Abstract:

A monitoring interface, includes logic responsive to a pre-fork event, the pre-fork event responsive to a vfork system call. The pre-fork event includes indicia that identifies a child process to be created in accordance with the vfork system call. A method for controlling the execution of a child process created from a parent process, where the parent process is monitored by a software tool includes, receiving indicia that a vfork system call will be executed by the parent process, suspending execution of the parent process, extracting a process identifier from the indicia of the vfork system call, the process identifier corresponding to a child process to be generated by the parent process when the parent process executes the vfork system call, setting a process monitor thread to observe the child process, and resuming execution of the parent process to enable the parent process to execute past the vfork system call.

US Classification:

711170, 714 5

Abstract:

Systems, methods, and device are provided for program stack handling. One method embodiment includes recognizing that a fault has occurred because a particular address range in a memory stack has been accessed. The method includes evaluating a current utilized size of regions in the memory stack. A particular address range between the current utilized size of regions in the memory stack is then relocated.

International Classification:

G06F 3/00
G06F 11/00

US Classification:

719310, 714100

Abstract:

To handle a signal received at an application context that employs a remote kernel service implemented in a server context different from the application context, the remote kernel service receives from the application context a first signal. Using a signal action vector file associated with the server context, a first action code associated with the first signal is ascertained. If the first action code represents a pseudo-handler, the remote kernel service is aborted.

Abstract:

In an embodiment of the invention, an apparatus and method for a target thread selection in a multi-threaded process perform the steps of receiving a signal that may or may not be masked by threads in the process; and searching a thread subset for a target thread that can handle the signal. A signal daemon may search for the target thread if the target thread is not found in the thread subset.

US Classification:

707/200000

Abstract:

A method in an operating system of a computer for allowing a plurality of application programs to interact with a plurality of subsystems, at least two application programs of the plurality of application programs being associated with two different personalities. The method includes providing a plurality of modules, each of the plurality of modules being associated with at least one personality and configured to interact with one of the plurality of subsystems, at least two modules of the plurality of modules being associated with the two different personalities. The method further includes providing a process state module for tracking personality data associated with the plurality of modules, thereby allowing a first application program of the two application programs to employ a first module of the two modules to interact with a given subsystem of the plurality of subsystems, the first application program and the first module being associated with one of the two different personalities, wherein the two application programs are configured to operate concurrently.

International Classification:

G06F007/00

US Classification:

707/201000

Abstract:

A file system in a computer is disclosed. The file system is configured to service file access requests between an application program and a first data storage subsystem. The file system includes a first persistent module coupled to receive a first file access request. The first persistent module is associated with the first data storage subsystem. The first file access request pertains to the first data storage subsystem. The file system includes a first transparently unloadable module coupled to the first persistent module to service the first file access request. The first transparently unloadable module is configured to be dynamically unloadable from the computer, wherein the first persistent module includes a blocking arrangement for blocking the first file access request at the first persistent module to allow the first transparently unloadable module to be unloaded without causing an error in the application program. The first persistent module includes memory for storing data necessary to allow the first file access request to be serviced in a manner substantially transparent to the application program after a substitute transparently unloadable module associated with the first data storage subsystem is loaded in place of the first transparently unloadable module.
