1* Note the globalbuf ...  to simplify things.
2* Also the volatile mergecmdline ... to ensure the compiler does not optimize
3* You may need to turn off ASLR as follows:
    $ echo 0 | sudo tee /proc/sys/kernel/randomize_va_space
4* A simple python script like the one attached should help you create the required command line arguments
5* Use the makefile attached for compilation.
6* A good way to start is to just try to print the operating system as output:
   - For example, the output of the program can simply be "Linux"
   - Then, try to add more details in the output, like the version number, etc.

7* Hint 1: The first part, ie. just getting the Linux printed onscreen, is the standard ret-to-libc attack
   Hint 2: Getting more details printed, would require a bit more thought.
