tee_client_system_session(9)

💅 NAME 💅

tee_client_system_session — okay bestie, this is the one that declares a session as a system session. Manual name: Kernel API Manual. Slay.

✨ SYNOPSIS ✨

int tee_client_system_session (struct tee_context *ctx , u32 session );

🎀 ARGUMENTS 🎀

• ctx — the TEE Context. Like, the whole TEE context vibe for this call.
• session — the Session id. The specific session we're hyping up.

🦋 DESCRIPTION 🦋

So this function requests TEE to provision an entry context that's ready to use for that session only. The provisioned entry context is used for command invocation and session closure — not for command cancelling requests. TEE releases the provisioned context upon session closure. Cleanup queen behavior, honestly.

Return < 0 on error, else 0 if an entry context has been provisioned.
