📦 version 7.3.1, in nixpkgs unstable

💅 llc_conn_ac_send_rr_rsp_f_set_ackpf(9) 💅

okay so this is a page from the Kernel API Manual (yes, the actual kernel manual, we're being fancy today 🎀) and the header up top is out here abbreviating for its life — it literally says llc_conn_ac..._f_set_ackpf(9) — but the real, full government name is llc_conn_ac_send_rr_rsp_f_set_ackpf. bestie, it's a mouthful, but it ate. 💅

✨ NAME ✨

llc_conn_ac_send_rr_rsp_f_set_ackpf — ack all rx PDUs not yet acked 🫶

🌸 SYNOPSIS 🌸

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

like, that's the whole vibe. two arguments, one int coming back at you. 💖

🦋 ARGUMENTS 🦋

  • sk — the current connection structure. your main character struct ngl 👑
  • skb — the current event. yes it's called skb, yes it's a struct sk_buff *, no we're not gonna make it weird 🌸

💀 DESCRIPTION 💀

okay so picture this: this action sends an RR response with the f-bit set to the ack_pf flag — as an acknowledge to all received PDUs that have not been acknowledged yet, if there are any, periodt. 🔥

the ack_pf flag is out here indicating whether a PDU has been received with the p-bit set to one. iykyk. 👀

and the return? it's giving simple: returns 0 for success, 1 otherwise. that's it. that's the whole personality. 💅

💜 SEE ALSO 💜

bestie go touch the kernel file ./net/llc/llc_c_ac.c — that's where it lives 🧚 and here's the whole friend group, no cap:

ngl if you're reading a kernel manpage at 2am with a strawberry lemonade in hand, you're literally living the dream. 🍓

okay that's the page bestie, mwah 💋 — this lil slice of heaven comes to you from ./net/llc, dated October 2026, and the footer is still out here calling it llc_conn_ac..._f_set_ackpf(9) because consistency is iconic. bye bye, go ack those PDUs 🎀🦋✨
