STRUCT UDP_BEARER(9)

✨ struct udp_bearer(9) ✨

okay so bestie, this page is fresh out of the Kernel API Manual, and we're doing a full vibe check on struct udp_bearer — it's literally the ip/udp bearer data structure. no cap, every field is main character energy, so let's get into it 💅

---

🌸 NAME 🌸

struct udp_bearer — ip/udp bearer data structure

---

🦋 SYNOPSIS 🦋

here's the whole struct, exactly as it appears, no edits fr fr:

       struct udp_bearer {
           struct tipc_bearer *bearer;
           struct sock *sk;
           u32 ifindex;
           struct work_struct work;
           struct udp_replicast rcast;
           spinlock_t rcast_lock;
           bool disabled;
        };

🎀 Members 🎀

okay so field-by-field, no skips, we're obsessed with details here:

• bearer — associated generic tipc bearer
• sk — bearer associated socket
• ifindex — local address scope
• work — used to schedule deferred work on a bearer
• rcast — associated udp_replicast container
• rcast_lock — serialize updates to rcast.list against concurrent updaters
• disabled — bearer is being torn down; reject further rcast.list additions

periodt. that's the whole cast 💖
