STRUCT PUBLICATION(9)

💅 NAME

struct publication — bestie, this struct is literally the little info card that says "hey, this service address (or range of addresses) is published" ✨ It's the tea about a published service address or a published service range 🎀

Ngl this one lives in the Kernel API Manual, so like… kernel-adjacent glamour, you know? 💜

🦋 SYNOPSIS

struct publication {
    struct tipc_service_range sr;
    struct tipc_socket_addr sk;
    u16 scope;
    u32 key;
    u32 id;
    struct list_head binding_node;
    struct list_head binding_sock;
    struct list_head local_publ;
    struct list_head all_publ;
    struct list_head list;
    struct rcu_head rcu;
 };

🌸 Members

• sr — the service range this publication is representing, periodt 💫
• sk — the address of the socket that's bound to this publication 🫶
• scope — the scope of the publication, and it's one of exactly two: TIPC_NODE_SCOPE or TIPC_CLUSTER_SCOPE 👑
• key — the publication key, and it's unique across the cluster, no cap 🔑
• id — the publication id 🎀
• binding_node — every publication from the same node that bound this one 💅 Check the receipts:
  • Remote publications: they live in node->publ_list; used by node/name distr to withdraw publications when the node is lost 😭
  • Local/node scope publications: they're in the name_table->node_scope list 🧚
  • Local/cluster scope publications: they're in the name_table->cluster_scope list 🌈
• binding_sock — all publications from the same socket which bound this one. Used by the socket to withdraw publications when the socket is unbound/released 💀
• local_publ — list of identical publications made from this node. Used by closest_first and multicast receive lookup algorithms 🍓
• all_publ — all publications identical to this one, whatever node and scope. Used by the round-robin lookup algorithm ⭐
• list — forms a list of publications in temporal order 🦋
• rcu — RCU callback head used for deferred freeing (it's giving "I'll clean up later" energy) 🙈
