STRUCT SSH_REQUEST(9)

💅 struct ssh_request(9) — Kernel API Manual 💅

okay so bestie, welcome to the struct ssh_request page — this is the Kernel API Manual and we are about to get into the SSH transport request lore. no cap, it's giving kernel internals but make it cute. ✨

🌸 NAME 🌸

struct ssh_request — SSH transport request. literally the whole point, and we're obsessed. 💖

✨ SYNOPSIS ✨

struct ssh_request {
    struct ssh_packet packet;
    struct list_head node;
    unsigned long state;
    ktime_t timestamp;
    const struct ssh_request_ops *ops;
 };

🫶 Members 🫶

• packet — the underlying SSH transport packet. that's the packet this request rides on, bestie. 🦋
• node — list node for the request queue and pending set. it's the lil link that lets the request sit in the queue and the pending set. 🎀
• state — state and type flags describing current request state (dynamic) and type (static). peep enum ssh_request_flags for possible options. this one is highkey doing double duty: dynamic state, static type. 💅
• timestamp — timestamp specifying when we start waiting on the response of the request. it gets set once the underlying packet has been completed, and it may be KTIME_MAX before that, or when the request does not expect a response. this is used for the request timeout implementation. ⏰
• ops — request Operations. the ops table for the request, periodt. 🔥
