caam_decap_blob(9)

🦋 NAME 🦋

okay so bestie, this is caam_decap_blob(9) from the Kernel API Manual, and its whole thing is literally decapsulate blob. That’s the name, that’s the vibe, we move. 💅✨

🌸 SYNOPSIS 🌸

int caam_decap_blob (struct caam_blob_priv *priv , struct caam_blob_info
*info );

🎀 ARGUMENTS 🎀

• priv — the instance returned by caam_blob_gen_init. Like, that’s where your blob setup came from, bestie. 🫶
• info — a pointer to blobbing info describing output key, input blob and key modifier buffers. It’s carrying the details for the output key, the input blob, and the key modifier buffers — very “paperwork but make it kernel” energy. 📋✨

💖 RETURN 💖

On success it returns 0 and sets info->output_len. On not-success it returns a negative error code. That’s it. No cap. 😭👑
