rte_security_macsec_sa(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💖 rte_security_macsec_sa — the MACsec SA glow-up 💖

okay so bestie, welcome to the rte_security_macsec_sa page from the DPDK Library Functions Manual 🌸 this one's a struct, and honestly? she's giving "secure association configuration, but make it fashion" ✨

✨ NAME ✨

rte_security_macsec_sa — literally the MACsec secure association (SA) configuration structure, no cap 👑

🦋 SYNOPSIS 🦋

#include <rte_security.h>

🎀 Data Fields 🎀

enum rte_security_macsec_direction dir
struct {
   const uint8_t * data
   uint16_t length
} key
uint8_t salt [RTE_SECURITY_MACSEC_SALT_LEN]
uint8_t an: 2
uint32_t ssci
uint32_t xpn
uint32_t next_pn

that's the whole squad right there 💅 nine-ish fields, all iconique, all accounted for.

🌈 Detailed Description 🌈

rte_security_macsec_sa is the MACsec secure association (SA) configuration structure 💖 that's it, that's the vibe. she holds the config for one SA and she does it well.

💜 Field Documentation 💜

💫 enum rte_security_macsec_direction dir

direction of SA 🧭 — which way the traffic's headed, bestie.

definition line 354 of file rte_security.h.

💫 const uint8_t* data

pointer to key data 🔑 — like, the actual key material lives over there, this is just the pointer.

definition line 357 of file rte_security.h.

💫 uint16_t length

key length in bytes 📏 — how many bytes we're working with, fr fr.

definition line 358 of file rte_security.h.

💫 struct { ... } key

MACsec SA key for AES-GCM 128/256 🔐 — both flavours, she's flexible like that.

💫 uint8_t salt[RTE_SECURITY_MACSEC_SALT_LEN]

96-bit value distributed by key agreement protocol 🧂✨ — not the kind of salt you put on fries, the cryptographic kind, iykyk.

definition line 361 of file rte_security.h.

💫 uint8_t an

association number to be used 🔢 — which AN slot we're rolling with.

definition line 363 of file rte_security.h.

💫 uint32_t ssci

Short Secure Channel Identifier, to be used for XPN cases 🆔 — yes, only for the XPN situations, don't come for her otherwise.

definition line 365 of file rte_security.h.

💫 uint32_t xpn

Extended packet number 🔢🔥 — the extended one, obviously.

definition line 367 of file rte_security.h.

💫 uint32_t next_pn

Packet number expected/ to be used for next packet of this SA 📬 — like, the next packet's number, this SA's business only.

definition line 369 of file rte_security.h.
