skb_flow_get_icmp_tci(9)

💖 NAME 💖

okay so bestie, meet skb_flow_get_icmp_tci(9) from the Kernel API Manual — this icon is here to extract ICMP(6) Type, Code and Identifier fields. that's the whole assignment. 🎀✨

✨ SYNOPSIS ✨

void skb_flow_get_icmp_tci (const struct sk_buff *skb , struct flow_dissector_key_icmp *key_icmp , const void *data , int thoff , int hlen );

🫶 ARGUMENTS 🫶

• skb — the sk_buff to extract from, bestie. it's giving "this is the packet we're working with" energy. 💅
• key_icmp — a struct flow_dissector_key_icmp to fill. yes, we are filling it. main character struct behavior, no cap. 👑
• data — raw buffer pointer to the packet. literally the packet data hookup. 🦋
• thoff — offset to extract at. that's the spot, bestie. 🎯
• hlen — packet header length. gotta know how long the header is, fr fr. 📏
