✨ ovpn_aead_crypto_req_sg ✨

Okay bestie, welcome to the ovpn_aead_crypto_req_sg(9) page — it's a kernel API manual situation and honestly it's a little niche but we're gonna slay it together 💅

🌸 NAME 🌸

ovpn_aead_crypto_req_sg — bestie, this one locates the scatterlist that sits right after the AEAD request inside a temporary buffer, and that buffer is the one you allocated using ovpn_aead_crypto_tmp_size. That's the whole vibe ✨

🦋 SYNOPSIS 🦋

struct scatterlist * ovpn_aead_crypto_req_sg (struct crypto_aead *aead ,
struct aead_request *req );

🎀 ARGUMENTS 🎀

• aead — the AEAD cipher handle, iconic, essential, the main character 🔥
• req — a pointer to the AEAD request structure, and it lives in the temporary buffer, no cap 🫶

💖 DESCRIPTION 💖

So like, here's the tea ☕: this function computes the starting address of the scatterlist — and that scatterlist is allocated immediately after the AEAD request structure. Like, right after. Adjacent. Besties in memory 🥰

And it aligns the pointer based on whatever the alignment requirements of the scatterlist structure are, because of course scatterlist has standards 💅

⭐ RETURN ⭐

It returns a pointer to the scatterlist. That's it, that's the gift 🎁

ngl bestie, go read those three siblings above before you start vibing with pointers in a temp buffer, iykyk 🙈

✨ ok that's the whole page, mwah 💋 ✨
