STRUCT BATADV_ICMP_PACKET_RR(9)

💅 struct batadv_icmp_packet_rr — ICMP RouteRecord packet 🦋

Okay so bestie, welcome to the Kernel API Manual ✨ (that's the manual name, iykyk) — and today's main character is this little struct: struct batadv_icmp_packet_rr, aka the ICMP RouteRecord packet. It's giving networking royalty 👑.

---

🌸 NAME 🌸

struct batadv_icmp_packet_rr — ICMP RouteRecord packet. That's it, that's the vibe 🎀

---

✨ SYNOPSIS ✨

struct batadv_icmp_packet_rr {
    __u8 packet_type;
    __u8 version;
    __u8 ttl;
    __u8 msg_type;
    __u8 dst[ETH_ALEN];
    __u8 orig[ETH_ALEN];
    __u8 uid;
    __u8 rr_cur;
    __be16 seqno;
    __u8 rr[BATADV_RR_LEN][ETH_ALEN];
 };

Not me typing out every single field so you don't have to 😭 Copy it exactly, no cap — those are the exact types and those are the exact names 💖

Every field gets its moment, periodt. Let's do a vibe check on each one:

• packet_type — batman-adv packet type, part of the general header. Literally the "what kind of packet am I" field 🌈
• version — batman-adv protocol version, part of the general header. She's the version tag, iconic ✨
• ttl — time to live for this packet, part of the general header. Lowkey the countdown clock 💀
• msg_type — ICMP packet type. Tells you which flavour of ICMP we're dealing with 🍓
• dst — address of the destination node. Where the packet's going, its final destination 🎯
• orig — address of the source node. Where it came from, its origin story 💜
• uid — local ICMP socket identifier. The socket's little name tag 🏷️
• rr_cur — number of entries the rr array. (Yes, that's the original wording — I'm not touching the facts, only the flair 😌)
• seqno — ICMP sequence number. Keeping track of order, main character energy 🔥
• rr — route record array. The whole route, recorded, the way that it holds the tea 🦋
