Your line of questioning doesn't really make any sense. Some operations ordinarily involve kernel syscalls, or trigger conditions which the kernel must handle. Others do not. However, the kernel can (if it "wishes" to) force the program to execute just one instruction at a time, with the kernel watching. Even something that involves the kernel may not be "sensed" unless some aspect of the kernel has been told to consider the fact that it happens noteworthy. So the real question is if the kernel has been primed to be looking for some type of operation or not. For various aspects of that, the answer is "usually", "depening on runtime options", "depending on compile time options" or "no, but you could modify it to" -- You received this message because you are subscribed to the Google Groups "Android Security Discussions" group.
