📦 version 7.3.1, in nixpkgs unstable

💅 llc_conn_ac_..._npta_by_rnr(9) 💅

okay so bestie, welcome to section 9 of the Kernel API Manual — the one where we talk about llc_conn_ac_adjust_npta_by_rnr. yes the header up top is abbreviated with ... because apparently even kernel devs get tired of typing. it's giving "we shortened the filename but not the vibes" ✨

🌸 NAME 🌸

llc_conn_ac_adjust_npta_by_rnr — decreases npta by one. that's it. that's the whole job. one (1) unit of decrease. a little subtraction moment. 💅

🦋 SYNOPSIS 🦋

int llc_conn_ac_adjust_npta_by_rnr (struct sock *sk , struct sk_buff
*skb );

look at that signature, she's iconic, she takes exactly two arguments, and she returns an int. no cap. 🔥

🎀 ARGUMENTS 🎀

  • sk — the current connection structure. like, the connection we're currently in, the main character of this operation 👑
  • skb — the current event. yes babe, the event itself is a struct sk_buff, that's just how this house rolls 🏠

✨ DESCRIPTION ✨

so here's the tea ☕ — after receiving dec_cntr times an RNR command, this action decreases npta by one. yep. it's a counter doing counter things.

and the return values? listen up:

  • returns 0 for success 🥳
  • returns 1 otherwise 🙈
ngl the "otherwise" is doing a LOT of heavy lifting there, but that's what the manpage says and we don't invent lore in this group chat. fr fr.

💜 SEE ALSO 💜

the kernel file lives at ./net/llc/llc_c_ac.c 🗂️ and bestie there is an entire squad of friends here, so let's give them all their moment:

like, the whole friend group showed up to the function's birthday party 🎂 and honestly? obsessed. iykyk 🌈

and that's the page, bestie 🫶 — brought to you by ./net/llc, dated October 2026, and filed under llc_conn_ac_..._npta_by_rnr(9) because apparently we're still abbreviating. mwah 💋✨
