STRUCT ATMEL_ECDH_CTX(9)

💜 struct atmel_ecdh_ctx(9) 💜

okay so this is a page from the Kernel API Manual — it's all about struct atmel_ecdh_ctx, bestie. literally one struct, four members, and a whole personality. let's get into it 🫶

---

✨ NAME ✨

struct atmel_ecdh_ctx — the transformation context 🦋 (yes that's its whole job description, and honestly? iconic.)

---

🌸 SYNOPSIS 🌸

here's the whole thing, verbatim, no cap:

struct atmel_ecdh_ctx {
    struct i2c_client *client;
    struct crypto_kpp *fallback;
    const u8 *public_key;
    bool do_fallback;
 };

like… look at her. four little members. main character energy fr fr 💅

---

🎀 Members 🎀

• client — the I2C client device 💖 that's the actual hardware buddy she's talking to.
• fallback — the ECDH fallback, and it's the one you use when the caller brings their own private key 🙈 iykyk.
• public_key — a cached copy of the public key, specifically the one that matches the private key the device generated ⭐ (caching queen.)
• do_fallback — a bool, and it's true whenever ECDH operations should be going through the fallback 🔥 simple as that.

---

🌈 Description 🌈

okay this is the important bit, so listen up 👑

The caller must not invoke set_secret while generate_public_key or compute_shared_secret are in flight. 🚨

like, genuinely — that's the rule. don't be doing it. no overlaps, no multitasking, no "oops I'll just sneak this in." the manpage is very clear and so am I 💀

and that's the tea 🍓 this page lives over in ./drivers/crypto and it's dated October 2026 — so like, future vibes. take care of her, she's struct atmel_ecdh_ctx(9) and she slayed 💅✨👑
