skb_frag_ref(9)

💅 skb_frag_ref — like, the kernel API manual, section 9 btw 🎀

okay so bestie, welcome to skb_frag_ref(9) — yes that's the manual section, we're in the big-kid kernel docs now, main character energy only ✨

🦋 NAME 🦋

skb_frag_ref — takes an addition reference on a paged fragment of an skb. that's it, that's the whole vibe 💅 (yes, the original really says "addition", not "additional" — we respect the lore 🫶)

---

✨ SYNOPSIS ✨

void skb_frag_ref (struct sk_buff *skb , int f );

literally the whole signature, no cap. it returns void, so don't go looking for a return value, there isn't one 🌸

---

💖 ARGUMENTS 💖

• skb — the buffer 🧚
• f — the fragment offset.

---

🔥 DESCRIPTION 🔥

so what it actually does: it takes an additional reference on the f'th paged fragment of skb. that's the entire plot, and honestly? it ate 💀👑

like, you point at fragment number f inside skb and you're like "mine now, also mine again" and the refcount goes up. iconic behavior, no notes 🌈
