dev_add_pack(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay bestie, this is dev_add_pack(9) — page title, iconic, and it's part of the Kernel API Manual (iykyk). its whole job? add packet handler. slay. ✨

🦋 SYNOPSIS 🦋

void dev_add_pack (struct packet_type *pt );

🎀 ARGUMENTS 🎀

  • pt — the packet type declaration. that's your ticket, bestie 🎟️

🌸 DESCRIPTION 🌸

So you're adding a protocol handler to the networking stack — main character move, honestly. The packet_type you pass in gets linked into kernel lists, and it may not be freed until it has been removed from the kernel lists. like, do not free it early, that is not the vibe 💀

This call does not sleep, so it can't guarantee that all CPUs that are in the middle of receiving packets will see the new packet type — nope, not until the next received packet. that's the caveat, fr fr 😭
