MPA(3)

📦 version 3.2, in debian trixie, fedora 43, fedora 44, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

💖 MPA(3) — the mpa 1.1 era, bestie 💖

okay so like. hi. welcome to the MPA manual page, version 1.1, and I promise it's less scary than it looks 🫶

✨ NAME ✨

packet.transport.mpa — it's the MPA module, that's it, that's the name 💅

🌸 DESCRIPTION 🌸

It decodes the MPA layer. that's the whole vibe. you feed it stuff, it unwraps the MPA goodness for you ✨

and if you're the kind of girl who reads the source material (respect, honestly), this is all coming from:

RFC 5044 Marker PDU Aligned Framing for TCP Specification

like. she's canon. she's cited. periodt 📜

🎀 CLASSES 🎀

🌈 class FrameType(packet.utils.Enum)

enum OpCode

(yes that's the whole thing, it's a little enum, let her live 🙈)

💜 class MPA(baseobj.BaseObj)

the MPA object herself. main character energy fr fr 👑

Usage:

from packet.transport.mpa import MPA

x = MPA(pktt)

Object definition:

MPA(
    [
        # MPA Full Operation Phase
        psize = int,  # Length of ULPDU
        pad   = int,  # Length of Padding bytes
        crc   = int,  # CRC 32 check value
    ] | [
        # Connection Setup
        ftype    = int,   # Frame type
        marker   = int,   # Marker usage required
        use_crc  = int,   # CRC usage
        reject   = int,   # Rejected connection
        revision = int,   # Revision of MPA
        psize    = int,   # Size of private data
        data     = bytes, # Private data
    ]
)

so there's two modes she can be in, and the object picks based on what you're doing: the MPA Full Operation Phase one (psize, pad, crc) or the Connection Setup one (ftype, marker, use_crc, reject, revision, psize, data). not me thinking that's actually kinda elegant 😭✨

🦋 Methods defined here:

  • __init__(self, pktt) — Constructor 💖

Initializes the object's private data. that's her job. she's doing it.

  • pktt: the Packet trace object (packet.pktt.Pktt), so this layer can reach up and grab its parent layers. iykyk — she needs the context, she's nosy in a productive way 🫶

💀 BUGS 💀

No known bugs.

not a single one. she's flawless. she ate and left no crumbs 👑✨ (lowkey terrifying but okay we love a clean record)
