STRUCT TIPC_SERVICE(9)

💅 struct tipc_service(9) — like, the Kernel API Manual page bestie 💅

okay so picture this: it's struct tipc_service(9), straight out of the Kernel API Manual, and she is the container. The main character. Every published instance of a service type lives in her house and she keeps track of all of them. Slay.

✨ NAME ✨

struct tipc_service — the container for all published instances of a service type 🫶 (yes, all of them. she's holding the whole roster.)

✨ SYNOPSIS ✨

struct tipc_service {
    u32 type;
    u32 publ_cnt;
    struct rb_root ranges;
    struct hlist_node service_list;
    struct list_head subscriptions;
    spinlock_t lock;
    struct rcu_head rcu;
 };

🎀 Members 🎀

• type — the 32 bit 'type' value for this service. that's her whole identity ngl 💅
• publ_cnt — an increasing counter for the publications in this service. it only goes up bestie, we love a growth mindset ✨
• ranges — an rb tree holding all the service ranges for this service. very organized, very demure 🌸
• service_list — links to adjacent name ranges in the hash chain. it's giving networking, it's giving connections 🔥
• subscriptions — the list of subscriptions for this service type. everyone who signed up for the notifs 💖
• lock — a spinlock controlling access to the pertaining service ranges/publications. she's the bouncer at the door, no cap 🫶
• rcu — the RCU callback head used for deferred freeing. not me being freed later, so on brand 😭
