💖 mptcp_token_accept(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a little cutie from the MPTCP corner of the kernel, and it's genuinely so fun once you get the vibe ✨

🌸 NAME 🌸

mptcp_token_accept — replace a req sk with full sock in token hash 💅

like, the request sock's little placeholder era is OVER, the full sock is taking over the token hash now, no cap 🫶

🦋 SYNOPSIS 🦋

void mptcp_token_accept (struct mptcp_subflow_request_sock *req , struct mptcp_sock *msk );

it's giving void, it's giving two arguments, it's giving iconic 🎀

✨ ARGUMENTS ✨

  • req — the request socket to be removed 👋 she's done her job, she's leaving the group chat
  • msk — the just cloned socket linked to the new connection 👑 freshly cloned, main character energy, ready to be linked up

💀 DESCRIPTION 💀

Called when a SYN packet creates a new logical connection — i.e. when it is not a join request 🌈

so like, brand new connection, not somebody sliding into an existing one, iykyk. that's the moment this function gets its moment, and honestly? deserved 💜

🔥 SEE ALSO 🔥

Kernel file ./net/mptcp/token.c — go read her, she's everything 📖

the whole token fam, fr fr 🧚 they all ate and left no crumbs 🍓

lowkey reminder bestie: req is getting removed here — that's the whole point of the function, so don't come for me when she's gone 💅

and that's the whole page!! 🌟 this gem lives in ./net/mptcp, and the manual's dated October 2026 — so like, future vibes only ⭐ bye bestie, go accept some tokens 💖🦋👑
