System Programming Vol I

– This book aims at making readers a programming expert and an excellent software architect using portable standard POSIX APIs at the operating system API level. It offers a very systematic education of all required knowledge, concepts, technologies, techniques, skills and problem solutions for programming at the system level. – This book contains the knowledge, skills and training that a computer science/engineering or software engineering student must have. – It’s a book that one must read if you are a software engineer developing system software in operating systems, database management systems, distributed systems, clustered systems, networking software, computer network security and client-server applications. – This book is intended as a textbook for system programming course at college, either a one-year System Programming course or a one-semester System Programming followed by another semester of Network Programming. It is also a reference or self-study guide for computer software engineers already working in the industry. – This book contains the best of author’s 30+ years of experiences across many fields in the U.S. computer software industry. – It features software design principles and programming tips for developing first-class software and author’s definition of first-class software. – Author presents elegant and very simple solutions for many common real-world problems such as update loss, cross-endian, alignment, backward and forward compatibility, socket applications, distributed applications, network security and PKI. – Following are some of the highlights from the book. – Pthreads programming. Using pthread local storage to solve reentrant deadlock problems, using mutex and condition variables to solve producer-consumer problems. Fix dangling mutex. Thread cancellation points. – Concurrency control using the fastest locking routines of your own, gaining performance improvements up to 80+%, ways to prevent deadlocks. – Strength and weakness of various interprocess communication mechanisms. Real program examples for designing shared memory and concurrent updates of shared memory. – In network socket programming, supporting IPv4 and IPv6, asynchronous connect, automatic reconnect, multicast, multithreaded server, looking up port number at run-time, fixed or dynamic ports, socket options, platform discrepancies and performance tuning. – In distributed system programming, cross-endian, alignment issues, versioning, maintaining backward and forward compatibility, and designing in defense of Denial of Service (DOS) attacks are discussed and program examples are provided. – On computer network security, aspects of security covered include authentication, secrecy, message integrity and non-repudiation. Symmetric and asymmetric cryptography. Client-server programs doing encryption/decryption, message digest, HMAC, digital signature, and SSL/TLS are provided. SSL handshake messages. SSL/TLS programming using OpenSSL. PKI. Creating all self-signed X.509 certificates, converting between different certificate file formats, verifying certificates signed by multiple chains of CAs, requiring client authentication in SSL/TLS. – 200+ ready-to-use example C programs which were tested in RedHat Linux, IBM AIX, Oracle/Sun Solaris, HP HP-UX, and Apple Darwin. The networking example programs were tested in Windows as well. – Volume I contains chapters 1-11. Volume II contains chapters 12-16. – Read this book to become an expert in computer system programming and an excellent software architect. – In August 2021, this book is recommended by Bookauthority as one of the best Network Programming books. And it has had sales in US, Canada and Germany.
