skcipher_request_set_tfm(9)

skcipher_request_set_tfm(9) 💖

okay bestie, welcome to the Kernel API Manual — this one is short, sweet, and literally about updating the cipher handle reference in a request. ✨

🎀 NAME 🎀

skcipher_request_set_tfm — update cipher handle reference in request. No cap, that’s the whole name vibe.

🌸 SYNOPSIS 🌸

void skcipher_request_set_tfm (struct skcipher_request *req , struct crypto_skcipher *tfm );

🦋 ARGUMENTS 🦋

• req — the request handle to be modified. This is the one getting the little glow-up. 💅
• tfm — the cipher handle that shall be added to the request handle. Slay, that’s the swap. 🫶

✨ DESCRIPTION ✨

Okay so here’s the tea: this function lets the caller replace the existing skcipher handle in the request data structure with a different one. 💖 That’s it. That’s the whole flex. It’s giving “swap the handle, keep the request,” fr fr. 🌸

The return type is void, so there’s no return value to catch — it’s just doing the update and moving on. ✨
