STRUCT SEC_ALG_TFM_CTX(9)

okay bestie, welcome to the struct sec_alg_tfm_ctx(9) manual page — this is the Kernel API Manual, and we're about to make this struct make sense 💖✨

✨ NAME ✨

struct sec_alg_tfm_ctx — hardware specific tranformation context 💅

🦋 SYNOPSIS 🦋

       struct sec_alg_tfm_ctx {
           enum sec_cipher_alg cipher_alg;
           u8 *key;
           dma_addr_t pkey;
           struct sec_bd_info req_template;
           struct sec_queue *queue;
           struct mutex lock;
           u8 *auth_buf;
           struct list_head backlog;
        };

🎀 Members 🎀

• cipher_alg — the cipher algorithm that's enabled, and it includes the encryption mode ✨
• key — where the key storage lives, if key storage is required 🔑
• pkey — the DMA address for the key storage, bestie 💫
• req_template — a request template so setup doesn't have to start from scratch — it saves time, fr fr ⏱️
• queue — the hardware queue associated with this tfm context 👑
• lock — a mutex that protects key and pkey to make sure they stay consistent, no cap 🔒
• auth_buf — the current context buffer for auth operations 🫶
• backlog — the backlog queue used for cases where our buffers aren't large enough 😭
