This is an easy buffer overflow chall, and you're even given the give_shell function. Just overwrite RSP with the address of the give_shell function to get shell.

Unfortunately you're not really providing enough detail. The "easy overflow" had a bit of a twist in that the buffer was circular and you couldn't just do a basic overflow. You also don't provide the contents of `run_circles_in.txt`, so there is nothing here for people to learn from. If you could share some more detail, that would be really great.
