get_mangled_key(9)

✨ NAME ✨

okay so bestie, this is get_mangled_key(9) from the Kernel API Manual 💅 and it does exactly what it says: mangles the key if a mangle act exists. That's the whole assignment, no cap 🫶

🌸 SYNOPSIS 🌸

void * get_mangled_key (struct flow_rule *rule , void *buf , u32 offset
, size_t key_sz , enum flow_action_mangle_base htype );

🎀 ARGUMENTS 🎀

• rule — the rule that carries the actions, like it's the main character holding the action bag 👜
• buf — pointer to the key that's getting mangled ✨
• offset — used to adjust the mangled offset in the L2/L3/L4 header 🧚
• key_sz — the key size, periodt 📏
• htype — the mangling type, iykyk 👑

💖 DESCRIPTION 💖

It returns buf, which is where the mangled key stores. That's literally the whole glow-up: the return value is the buffer where the mangled key lives 🫶
