STRUCT CAAM_HASH_CTX(9)

💖 struct caam_hash_ctx(9) 💖

okay bestie, buckle up — this is a page from the Kernel API Manual, and it's literally all about struct caam_hash_ctx, which is the ahash per-session context. that's the whole vibe. per-session. ahash. context. slay 💅

---

✨ NAME ✨

struct caam_hash_ctx — the ahash per-session context, no cap 🫶

---

🌸 SYNOPSIS 🌸

here's the whole struct, copied exactly because we do not mess with code in this house:

struct caam_hash_ctx {
    struct caam_flc flc[HASH_NUM_OP];
    u8 key[CAAM_MAX_HASH_BLOCK_SIZE];
    dma_addr_t flc_dma[HASH_NUM_OP];
    struct device *dev;
    int ctx_len;
    struct alginfo adata;
 };

---

🎀 Members 🎀

ok so these are the fields, and yes we're going through every single one because they all matter:

• flc — the Flow Contexts array. it's giving "array of flow contexts" and honestly? iconic ✨
• key — the authentication key 🔑 like, the actual key. keep it safe.
• flc_dma — the I/O virtual addresses of the Flow Contexts. yes, addresses, plural, it's an array too 🌈
• dev — the dpseci device. that's literally what it says, so that's what you get 💀
• ctx_len — size of the Context Register. a length. for the context. very demure, very mindful.
• adata — hashing algorithm details 🧚 the algorithm's whole little info packet

• struct caam_ctx(9) — its cousin, also a struct, also important 💜

lowkey reminder bestie: this lives under ./drivers/crypto/caam in the kernel tree, so that's where you'll find the friends 🍓
