Foundations of Linux ARM64: Debug, Disassemble, and Reverse
Gain insights into debugging C/C++ programs on Linux ARM64, delve into program disassembly, probe memory/register changes using GDB, and discover techniques for core dump analysis and assembly-level debugging.
The GNU Debugger (GDB) is used for debugging C/C++ programs in LINUX/UNIX environments. It is a good tool to investigate what is happening inside a program and how the contents inside the memory are changed with the execution of the program.
The main focus of the course is the disassembly of the program. You’ll use the Linux ARM64 which is a popular RISC architecture. You’ll use simple operations in C/C++ such as assignment, increment, addition, multiplication. With the help of the GDB, you will probe into the contents of the registers and memory. You'll learn how they are changed while executing basic operations. With the help of the disassembly output, you’ll learn how a simple C/C++ program can be reconstructed. The disassembly output is important for debugging and core dump analysis.
By the end of this course, you should be able to debug the programs and memory contents at assembly level when a program executes or probe into the problem when a program crashes.
