PROBE::TCP.RECEIVE(3stap)

💖 PROBE::TCP.RECEIVE 💖

okay bestie, sit down, hydrate, because we're talking about probe::tcp.receive from the Networking Tapset — that's the SystemTap tapset reference, page PROBE::TCP.RECEIVE(3stap). it's giving "I watch every single TCP packet slide into the stack" and honestly? iconic behavior.

---

✨ NAME ✨

probe::tcp.receive — no cap, this probe fires the moment a TCP packet gets received. that's the whole vibe. 💅

---

🦋 SYNOPSIS 🦋

probe tcp.receive {}

look at her. no arguments, no drama, just a little probe point standing there in her main character energy. 🎀

---

🌸 VALUES 🌸

these are all the lil variables you get to play with once the probe fires. every single one, in order, zero skips:

• name — the name of the probe point. yes bestie, she knows her own name. self-aware queen. 👑
• family — the IP address family. v4, v6, whichever, she's not judging. 🌈
• fin — the TCP FIN flag. this is the "ok bye, closing the connection" flag. 😭
• iphdr — the IP header address. the receipts of where the header lives in memory. 🧚
• urg — the TCP URG flag. urgent, as the name suggests. she said it's urgent, so it's urgent. 💀
• syn — the TCP SYN flag. the classic "hi, can we talk?" handshake opener. 🫶
• ack — the TCP ACK flag. the "yes bb I heard you" flag. acknowledged, periodt.
• psh — the TCP PSH flag. push it, send it straight up to the app. 🔥
• saddr — a string representing the source IP address. who's calling? 💜
• dport — the TCP destination port. where is this packet trying to get in? 🚪
• daddr — a string representing the destination IP address. where's it headed?
• sport — the TCP source port. where it came from, fr fr.
• protocol — packet protocol from driver. straight from the driver, untouched, no filter. ✨
• rst — the TCP RST flag. the "nvm, conversation over" flag. harsh but fair. 💀
