STRUCT BATADV_TP_SENDER(9)

💅 struct batadv_tp_sender(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs for fun now, this is who we are 💖. Today's main character is struct batadv_tp_sender, aka the sender tp meter private variables per session. Say that five times fast, I dare you 😭.

---

✨ NAME ✨

struct batadv_tp_sender — the sender tp meter's private variables, one lil set per session 🎀

---

🌸 SYNOPSIS 🌸

struct batadv_tp_sender {
    struct batadv_tp_vars_common common;
    unsigned long start_time;
    atomic_t send_result;
    struct delayed_work finish_work;
    struct completion finished;
    u32 test_length;
    u8 icmp_uid;
    struct batadv_tp_sender_cc cc;
    spinlock_t cc_lock;
    atomic64_t tot_sent;
    wait_queue_head_t more_bytes;
    u32 prerandom_offset;
    spinlock_t prerandom_lock;
 };

look at her. twelve members. a whole vibe. no cap, she's serving struct realness 👑

🫶 Members 🫶

• common — the shared batadv_tp_vars_common bits, and heads up: it must be first member. like, the way that it has to be first, no negotiating 💀
• start_time — the start time, measured in jiffies ⏱️
• send_result — sits at 0 while sending is still ongoing, and otherwise it's an enum batadv_tp_meter_reason. so basically zero = we're still going, anything else = we have opinions 🔥
• finish_work — the work item for the finishing procedure, aka the cleanup era ✨
• finished — a completion that gets signaled when a sender thread exits. bye bestie, thread's done 🦋
• test_length — the test length in milliseconds 🍓
• icmp_uid — the local ICMP "socket" index (yes, "socket" in quotes, she's quirky like that) 🙈
• cc — the congestion control variables, the actual brain cell of this operation 🧠
• cc_lock — the lock that protects cc. don't touch cc without her 🔒
• tot_sent — how much data has been sent/ACKed so far. the humble flex counter 📈
• more_bytes — the waiting queue anchor you park on while waiting for more ack/retry timeout ⏳
• prerandom_offset — the offset inside the prerandom buffer 🎯
• prerandom_lock — the spinlock protecting access to prerandom_offset. again: lock first, look second 💅
