💅 qcom_scm_import_ice_key — Kernel API Manual ✨

okay bestie, so we're in the Kernel API Manual today and the star of the show is qcom_scm_import_ice_key(9) — yes it's a mouthful, yes it slays, let's get into it 🎀

✨ NAME ✨

qcom_scm_import_ice_key — the one that imports your key for storage encryption 🔐💖

🦋 SYNOPSIS 🦋

int qcom_scm_import_ice_key (const u8 *raw_key , size_t raw_key_size ,
u8 *lt_key , size_t lt_key_size );

that's the whole vibe check right there — one int coming back at you, four args going in 👑

🌸 ARGUMENTS 🌸

  • raw_key — the raw key you're importing, the actual main character of this operation 💫
  • raw_key_size — how big raw_key is, in bytes. yes, bytes, we measure things here 📏
  • lt_key — your output buffer, where the long-term wrapped key gets to live 🏡✨
  • lt_key_size — size of lt_key in bytes, and listen — it must be the exact wrapped key size that the SoC uses. not close, not approximate, exact. the SoC is not flexible about this and honestly respect 😭

💜 DESCRIPTION 💜

So what does it do? It imports a raw key and hands you back a long-term wrapped key. That's it, that's the plot 🫶

Under the hood it uses the SoC's HWKM to wrap the raw key using the platform-specific Key Encryption Key — hardware doing hardware things, no cap 🔥💅

⭐ RETURN ⭐

0 on success, -errno on failure. iconic behavior, no notes 🙈💖
