rte_crypto_sym_vec(3)

💖 rte_crypto_sym_vec 💖

okay bestie, welcome to the rte_crypto_sym_vec(3) page — section 3, Library Functions Manual, we're in DPDK land, and this lil struct is so much less scary than it looks, i promise 🫶

---

✨ NAME ✨

rte_crypto_sym_vec — the raw data operation descriptor struct, and like, it's kind of a whole vibe check for a batch of crypto ops 👑

---

🌸 SYNOPSIS 🌸

#include <rte_crypto_sym.h>

🎀 Data Fields

• uint32_t num
• struct rte_crypto_sgl * src_sgl
• struct rte_crypto_sgl * dest_sgl
• struct rte_crypto_va_iova_ptr * iv
• struct rte_crypto_va_iova_ptr * digest
• int32_t * status

---

🦋 Detailed Description 🦋

It's the Raw data operation descriptor, bestie. It's supposed to be used with the synchronous CPU crypto API call, or with the asynchronous RAW data path API call — those are literally its two whole purposes, it's giving very "i have one job and i slay at it" energy 💅

ngl this struct has main character energy: it's defined at line 71 of the file rte_crypto_sym.h. remember that. it's in the lore. ✨

💜 Field Documentation 💜

🌈 uint32_t num

It's the number of operations to perform — like, how many things are we doing today, bestie? that many. 🍓

Defined at line 73 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_sgl* src_sgl

An array of SGL vectors. yes queen, arrays. we love a list of them. 💖

Defined at line 75 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_sgl* dest_sgl

An array of SGL vectors for OOP — and here's the important part, no cap: keep it NULL for inplace. like, do NOT fill this in if you're doing inplace, that's the whole rule, i don't make them i just report them 🙈

Defined at line 77 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_va_iova_ptr* iv

An array of pointers to cipher IV</array>. iv as in initialization vector, not as in the roman numeral, stay focused bestie 😭

Defined at line 79 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_va_iova_ptr* digest

An array of pointers to digest. mmm digest. like the algorithm ate your data and this is the receipt 💀

Defined at line 81 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_va_iova_ptr* auth_iv

An array of pointers to auth IV</array> — and this one is used for chain operation specifically. chain! not AEAD! keep them straight, i'm begging 🧚

Defined at line 86 of file rte_crypto_sym.h.

---

🌈 struct rte_crypto_va_iova_ptr* aad

An array of pointers to AAD</array> — that's Additional Authenticated Data, and it's used for AEAD operation. different field, different operation, don't mix them up or it's gonna be a bad time fr fr 🫶

Defined at line 88 of file rte_crypto_sym.h.

---

🌈 int32_t* status

An array of statuses for each operation, one per op, and the values are literally just:

• 0 on success 🎉
• errno on error 😭

so check your statuses. every single one. yes all of them. i said what i said. ⭐

Defined at line 96 of file rte_crypto_sym.h.
