💅 irdma_check_syn — a Kernel API Manual moment (section 9, bestie)

Okay so picture this: you're deep in the Kernel API Manual, section 9, and you've landed on irdma_check_syn. The whole job? Check for an error on a received syn ack. That's it. That's the vibe check. 🎀

✨ NAME ✨

irdma_check_syn — check for error on received syn ack 🦋

Like, it looks at a syn-ack that just showed up and goes "hmm, is something wrong here?" fr fr.

✨ SYNOPSIS ✨

int irdma_check_syn (struct irdma_cm_node *cm_node , struct tcphdr *tcph
);

Yep, that's the whole signature, no cap. Returns an int, takes two pointers, slays. 💅

🌸 ARGUMENTS 🌸

  • cm_node — the connection's node 🫶 (your main character struct — the connection you're checking on)
  • tcph — a pointer to the tcp header 👑 (the actual packet bits you're inspecting)

🦋 SEE ALSO 🦋

Soooo many cousins, bestie. Start with the kernel file itself — ./drivers/infiniband/hw/irdma/cm.c — and then the whole friend group:

That's the whole group chat, everyone showed up. 🔥

Heads up bestie: this page only tells you the name, the signature, the two arguments and the friend list — that's literally everything the original gives you, so don't go reading extra behaviour into it, mwah. 💖

Bye bestie! 🧚 This lil' page lives under ./drivers/infiniband/hw/irdma and it's stamped October 2026 — go forth and check those syn acks, you gorgeous genius. ⭐💜
