STRUCT FLOW_DISSECTOR_KEY_ADDRS(9)

💖 STRUCT FLOW_DISSECTOR_KEY_ADDRS(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for struct flow_dissector_key_addrs, and honestly? it's a whole vibe. it's the little container that holds all your address-y goodness, and it's serving main character energy in ./include/net/flow_dissector.h. no cap, it's iconic.

---

✨ NAME ✨

struct flow_dissector_key_addrs — literally just the address bucket, that's it, that's the whole name 🫶

---

🦋 SYNOPSIS 🦋

here's the shape of it, fr fr — a struct wrapping one anonymous union with three possible members inside:

struct flow_dissector_key_addrs {
    union {
      struct flow_dissector_key_ipv4_addrs v4addrs;
      struct flow_dissector_key_ipv6_addrs v6addrs;
      struct flow_dissector_key_tipc tipckey;
    };
 };

the way that union just holds one of these at a time — it's giving "pick a lane, queen" 💅

---

🎀 Members 🎀

• {unnamed_union} — anonymous 🌸 like, it has no name of its own, it just exists to hold the three below. lowkey mysterious, highkey useful.
• v4addrs — IPv4 addresses 💜 the classic, the OG, the one your router knows by heart.
• v6addrs — IPv6 addresses 🔥 the long ones, the future, the ones with all the colons.
• tipckey — TIPC key ⭐ the niche icon of the group, TIPC said "I'm here too bestie" and honestly, slay.

🌸 the cute sign-off 🌸

this page lives in ./include/net, dated October 2026, and if you ever forget what it's called it's struct flow...or_key_addrs(9) (yes the abbreviation is doing its own thing, we love her anyway 💀). mwah, go dissect some flows, bestie! 🧚‍♀️💖✨
