STRUCT SSH_FRAME(9)

🦋 struct ssh_frame(9) 🦋

okok so you're in the Kernel API Manual, bestie, and this page is allll about struct ssh_frame — the SSH communication frame. that's it, that's the NAME section, slay 💅

✨ SYNOPSIS ✨

struct ssh_frame {
    u8 type;
    __le16 len;
    u8 seq;
 };

like literally look at it. three fields. it's giving minimalist icon energy 🎀

🌸 Members 🌸

• type — what kind of frame this is, babe. it's a u8, and for the actual deets you gotta hit up enum ssh_frame_type. that's where the lore lives 👑
• len — the length of the frame payload that comes directly after the CRC for this frame. and no, it does not include the final CRC for that payload — do not come for me on this, it's right there in the spec 🙈 __le16, so keep your endianness in check fr fr.
• seq — the sequence number for this message/exchange. u8. lowkey just a lil counter doing its thing so everything stays in order ✨
