The Role of Threads
Explore the concept of threads in Linux core dump analysis, including how threads execute code, share process space, and maintain stack regions. Understand how thread stacks store execution history, and learn to interpret stack traces with GDB to diagnose process and kernel behaviors.
What are threads?
We will now look at another important fundamental concept of Linux core dump analysis: a thread or a lightweight process (LWP). A thread is a unit of execution, and there can be many threads, LWPs, for a given process (all of them share the same process space).
Every thread executes some code and performs various tasks. Every thread has its ID (LWP ID). In this course, we’ll also learn how to navigate between process threads.
Note: The threads transition to kernel space via the
