John : Many people misunderstand that the principle of hacking is stack overflow. However,  I tell you it's wrong.  Why ? See the 1st picture.  The clock line and output line of R1 are virtual. 

.

Me: That mean it's 2nd level. 

.

John : You gotta hack the 1st level of clock line and the 1st level of output line cause they are real and at the 1st level.

Me: Fine. 

.

John : There's a "packaged" Wave which is generated by Clock line of RJ45.  It's at the down cycle. 

.

John : Correct.  Inside this "Packaged" wave,  there're 2 carrier waves.  They are the carrier wave of R0 and the carrier wave of R1.

.

Me: Between the carrier wave of R0 and R1, there is a gap.

.

John : This Gap point block R0 from overflowing to R1. This Gap point also block R1 from Left Shifting to R0.

.

Me: Therefore,  Stack overflow and Left Shifting aren't the principle of hacking.
