STRUCT TIPC_BC_BASE(9)

✨ struct tipc_bc_base(9) ✨

okay so bestie, this is a page from the Kernel API Manual and it's literally all about struct tipc_bc_base — the base structure for keeping broadcast send state 💅 it's giving "the group chat's admin settings" energy, no cap.

🌸 SYNOPSIS 🌸

struct tipc_bc_base {
    struct tipc_link *link;
    struct sk_buff_head inputq;
    int dests[MAX_BEARERS];
    int primary_bearer;
    bool bcast_support;
    bool force_bcast;
    bool rcast_support;
    bool force_rcast;
    int rc_ratio;
    int bc_threshold;
 };

like, that's the whole vibe right there 💖 every field is a little main character, so let's meet them 🫶

🎀 Members 🎀

• link — the broadcast send link structure. this is the icon holding the whole send situation together ✨
• inputq — the data input queue; it will only carry SOCK_WAKEUP messages. lowkey exclusive, it's a VIP queue only 💅
• dests — an array keeping the number of reachable destinations per bearer. think of it as the headcount per bearer 👑
• primary_bearer — a bearer having links to all broadcast destinations, if any. the one that knows everybody 🦋
• bcast_support — indicates if the primary bearer, if any, supports broadcast 🌈
• force_bcast — forces broadcast for multicast traffic. no discussion, broadcast it is periodt 🔥
• rcast_support — indicates if all peer nodes support replicast. a whole-cluster vibe check 💀
• force_rcast — forces replicast for multicast traffic. same energy, replicast edition 🍓
• rc_ratio — dest count as percentage of cluster size where the send method changes. this is the literal tipping point, the "we're switching things up" ratio 🧚
• bc_threshold — calculated from rc_ratio; if dests > threshold, use broadcast ⭐ so yeah, cross that line and broadcast takes over 👑
