STRUCT SSH_COMMAND(9)

💅 struct ssh_command(9) 💅

okay so bestie, we're deep in the Kernel API Manual today and the star of the show is struct ssh_command — it's literally the payload of a command-type frame. that's the whole vibe. it's the lil' bundle of bytes that rides inside an SSH frame when the frame is carrying a command. iconic behavior honestly 🎀

---

✨ NAME ✨

struct ssh_command — Payload of a command-type frame. yes that's it. that's the name. short, sweet, ate. 💖

---

🌸 SYNOPSIS 🌸

struct ssh_command {
    u8 type;
    u8 tc;
    u8 tid;
    u8 sid;
    u8 iid;
    __le16 rqid;
    u8 cid;
 };

look at it. seven little fields. so demure. so mindful. 🦋

👑 Members 👑

okay so let's meet the cast, because every single one of these matters and i'm not skipping a single one of them, periodt:

• type — the type of the payload. peep enum ssh_payload_type for the full menu. for this struct it should be SSH_PLD_TYPE_CMD. like, that's its whole personality. 💅
• tc — command target category.
• tid — Target ID. it's the field that indicates the target of the message. iykyk. 🎯
• sid — Source ID. indicates the source of the message. who sent it, basically. 🫶
• iid — Instance ID.
• rqid — Request ID. this one's a lil' matchmaker 💖 it's used to match requests with responses and to differentiate between responses and events. lowkey the most socially connected field in here.
• cid — Command ID.

reminder bestie: type should be SSH_PLD_TYPE_CMD for this struct — that's straight from the page, not me being dramatic (okay it's a little me being dramatic but it's also true 💀).

🌈 and that's the whole page, mwah 💋 this one came from ./include/linux/surface_aggreg... and it's dated October 2026 — so yeah, future vibes only. catch you in the next manpage, bestie! 🧚💜
