The reasons why most of these are disabled is because they usually require runtime support (which you in a basic kernel don't have). For a more thorough explanation, see the [[C++]] article. There is also an article about the [[GCC_Stack_Smashing_Protector|stack smashing protector]] if you want to enable --stack-protector. |
