Some of those topics are basic UNIX programming things (signals, threads, process state, controlling tty). Others are features of the operating system, so you would want something Linux-specific that tells you about kernel programming or kernel features you can use in your applications (security labels, scheduling classes, control groups, kernel threads, etc). Still others are features of the OS & cpu's execution of programs (instruction/stack pointers), you'll want to learn Assembly for that.
Sorry I don't have reading recommendations. I don't really read as much as just diving into man pages and looking up guides online. Hacker habits...
No problem. I do know what some of the points mean (signals, threads, control groups, instruction/stack pointers, etc.), just did not know some of the others (like security labels, threads vs. kernel threads, etc.). I guess some of those topics might not be found in one or a few books, more like scattered across books, articles, man pages etc. ...
