STRUCT SE_CRYPTO_REQUEST(9)

💅 struct se_crypto_request(9) — kernel API manual, bestie edition

okay so picture this: you're deep in the kernel API manual (that's the manual name, iykyk) and you bump into struct se_crypto_request. She's the SE crypto request structure, and honestly? main character energy. Let's get into it 🎀

---

✨ NAME ✨

struct se_crypto_request — the SE crypto request structure. that's her. that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

here's the whole glow-up, verbatim, don't touch a single character:

struct se_crypto_request {
    u8 opcode;
    gfp_t gfp;
    u32 flags;
    u64 ctx_handle;
    struct gphdr gph;
    union se_req_ctrl ctrl;
    u64 *orh;
    u64 *comp;
    struct scatterlist *src;
    struct scatterlist *dst;
 };

like. look at her. iconic. 🫶

🦋 Members 🦋

time for the member-by-member vibe check, no cap:

• opcode — the request opcode (enc/dec). she's either encrypting or decrypting, pick a lane bestie ✨
• flags — flags from the crypto subsystem. the little stickers on the outside of the notebook, fr.
• ctx_handle — the crypto context handle. your VIP pass to the context 💅
• gph — GP Header.
• ctrl — Request Information. yes that's the whole description, and yes it's giving mysterious 🌈
• orh — ORH address.
• comp — completion address. where we all meet up when we're done 🎀
• src — the input sglist. what goes in 🍓
• dst — the output sglist. what comes out ⭐

quick note bestie: gfp is absolutely sitting up there in the struct being all gfp_t gfp; and living her life, but the Members list does not say anything about her. so we're not gonna make anything up. we simply respect her privacy 🙈
