okay bestie, this is xt_find_jump_offset(9), straight from the Kernel API Manual, and we're about to make jump-offset checking make sense 💅✨

🌸 NAME 🌸

xt_find_jump_offset — checks if target is a valid jump offset, no cap 🎯

✨ SYNOPSIS ✨

bool xt_find_jump_offset (const unsigned int *offsets , unsigned int target , unsigned int size );

🎀 ARGUMENTS 🎀

• target — the jump target we're searching for, the one getting the vibe check 👀💅
