Sathish worked as a Member Technical Staff for the L5 MPRAS-OS Support and

Maintenance project. He was involved in Network Module Team.

Project Title MPRAS-OS Support and Maintenance

Duration 3.3 Years

Programming C, gdb, kdb, bash

Languages/Tools

Project Description:

Enhancement to MP-RAS Intel 8254X Gigabit Ethernet driver:

The project targeted at improving the throughput and performance of the

Intel gigabit adapter. The memory management algorithm of the gigabit

driver on MP-RAS had to be re-designed to improve the throughput of the

adapter.

The new design was intended to reduce the number of kernel memory

allocation requests made by the driver by maintaining a private memory pool

for the driver and re-using the same.

New security package development for MP-RAS OS:

This is an effort to develop a new package for securing the file integrity

of the MPRAS file system. The newly developed package included security

tracking tools and associated secured Tracking files.

As a part of this effort a wrapper was also developed around the package

installation utilities Pkgadd and pkginstall to retain file integrity with

respect to secured tracking file.

Evaluate Intel 100pro Errata for MP-RAS Network driver:

This was an effort to evaluate the Intel 100pro network adapter errata

document and provide fix to MP-RAS Intel 100pro network driver. Also as a

part of this effort the intermittent link quality problem observed between

Cisco Catalyst 2950T. Switch port connected to a NCR S26 UNIX MP-RAS server

with Intel 82559 adapter was rectified.

Enhancement to Network statistics tool 'Netstat' in MP-RAS:

This is an effort to provide an enhancement in netstat tool to print the

process id associated with the port. Netstat is a tool to display the

contents of various network-related data structures. An option has been

added to display PID associated to a UNIX or TCP socket.

Developed diagnostics tools for MP-RAS and Linux:

The node diagnostics tools were designed to test the software and hardware

components of a typical MP-RAS node and minimally diagnose problems with

node configuration, functionality or performance.

This software was developed to facilitate decrease in down times of a node

by running periodic health checks on various components and by early

diagnosis of symptoms.

MP-RAS Vulnerability analysis:

This project is part of an ongoing effort towards strengthening security

aspects of NCR products. This project involved study of existing MP-RAS

implementation, verification of publicly known vulnerabilities existence in

various MP-RAS subsystems and providing solutions for fixing the

vulnerabilities. The verification effort involved reference to various

vulnerability databases such as CERT Advisories, SCO Security

vulnerabilities, Security Focus and usage of publicly available exploit

tools.

Automation of Generic UTP for Network adapters:

This is an effort to automate the generic test plan used to test the MP-RAS

network adapters (Ethernet, token ring or fddi). The automated test tool

was used to certify MP-RAS networking adapters and to test networking

modules ILD and INET.

The automated test tool was designed to perform the following

functionalities.

. Functionality testing of library commands and protocols.

. ILD tests.

. DLM tests

. TCP/IP tests

. Stress tests

Roles and Responsibilities in the Project:

. Provided solutions to defects at customer location.

. Implement Enhancement designs.
