STRUCT SA_CMDL_UPD_INFO(9)

🎀 struct sa_cmdl_upd_info — the kernel API manual, bestie edition 🎀

Hiii okay so we're talking about struct sa_cmdl_upd_info(9) from the Kernel API Manual today, and honestly? It's giving "command label updation info" and it ate. Buckle up, this one's a whole struct and she has a LOT of members. 💅

✨ NAME ✨

struct sa_cmdl_upd_info — command label updation info. Yes that's really what it's called, no I did not make that up, and yes the whole point of this struct is keeping track of update info for a command label. Iconic behavior tbh. 🫶

---

🌸 SYNOPSIS 🌸

Okay so here's the whole thing, character for character, look at her:

struct sa_cmdl_upd_info {
    u16 flags;
    u16 submode;
    struct sa_cmdl_param_info       enc_size;
    struct sa_cmdl_param_info       enc_size2;
    struct sa_cmdl_param_info       enc_offset;
    struct sa_cmdl_param_info       enc_iv;
    struct sa_cmdl_param_info       enc_iv2;
    struct sa_cmdl_param_info       aad;
    struct sa_cmdl_param_info       payload;
    struct sa_cmdl_param_info       auth_size;
    struct sa_cmdl_param_info       auth_size2;
    struct sa_cmdl_param_info       auth_offset;
    struct sa_cmdl_param_info       auth_iv;
    struct sa_cmdl_param_info       aux_key_info;
    u32 aux_key[SA_MAX_AUX_DATA_WORDS];
};

Like, she's long, she's detailed, she has a whole little struct sa_cmdl_param_info friend group. Main character energy fr fr. 👑

💖 Members 💖

Okay bestie, time for the roll call — every single member, no skipping, because we do NOT leave anyone out of the group chat:

• flags — flags in command label. Yeah, flags. In the command label. Keeping it simple, we love that for her. ✨
• submode — Encryption submodes. The vibes of the encryption, essentially. 🔥
• enc_size — Size of first pass encryption size. First pass!! There's a whole second pass coming, don't worry. 🦋
• enc_size2 — Size of second pass encryption size. See? Told you. 💜
• enc_offset — Encryption payload offset in the packet. Where the payload is chilling inside the packet. 📍
• enc_iv — Encryption initialization vector for pass2. (Yes, both enc_iv and enc_iv2 say pass2 in this manual. We're just reporting the facts, no cap. 🙈)
• enc_iv2 — Encryption initialization vector for pass2. Again. Second verse, same as the first. 😭
• aad — Associated data. That's it, that's the whole description, and honestly? Respect the brevity. 🎀
• payload — Payload info. The payload's info. The info about the payload. Chef's kiss of a description. 🍓
• auth_size — Authentication size for pass 1. Note the space before the 1, we keep it exactly as written, we are nothing if not accurate. ⭐
• auth_size2 — Authentication size for pass 2. The sequel. 🌈
• auth_offset — Authentication payload offset. Where the auth payload sits. 🌸
• auth_iv — Authentication initialization vector. The auth-side IV, doing her little cryptographic thing. 🧚
• aux_key_info — Authentication aux key information. All the ~info~ about the aux key. 💫
• aux_key — Aux key for authentication. It's literally u32 aux_key[SA_MAX_AUX_DATA_WORDS]; — an array, bestie, she contains multitudes. 🔑

Lowkey a reminder that this is the struct sa_cmdl_upd_info(9) page from the Kernel API Manual, so if you're out here shipping crypto driver code, cite your sources bestie. 📚

Okay that's the whole page, mwah 💋 — brought to you by ./drivers/crypto, dated October 2026, and yes the footer says struct sa_cmdl_upd_info(9) one more time just to make sure you remember her name. Periodt. 💅✨🫶
